Quick assessment of literacy in primary care: the newest vital sign.

Abstract: PURPOSE Current health literacy screening instruments for health care settings are either too long for routine use or available only in English. Our objective was to develop a quick and accurate screening test for limited literacy available in Eng- lish and Spanish. METHODS We administered candidate items for the new instrument and also the Test of Functional Health Literacy in Adults (TOFHLA) to English-speaking and Spanish-speaking primary care patients. We measured internal consistency with Cronbach's and assessed criterion validity by measuring correlations with TOFHLA scores. Using TOFLHA scores 0.76 in English and 0.69 in Spanish) and correlates with the TOFHLA. Area under the ROC curve is 0.88 for English and 0.72 for Spanish ver- sions. Patients with more than 4 correct responses are unlikely to have low literacy, whereas fewer than 4 correct answers indicate the possibility of limited literacy. CONCLUSION NVS is suitable for use as a quick screening test for limited literacy in primary health care settings.

Prevalence of Multimorbidity Among Adults Seen in Family Practice

Abstract: PURPOSE There are few valid data that describe the extent of multimorbidity in primary care patients. The purpose of this study was to estimate its prevalence in family practice patients by counting the number of chronic medical conditions and using a measure that considers the severity of these conditions, the Cumulative Illness Rating Scale (CIRS). METHODS The study was carried out in the Saguenay region (Quebec, Canada) in 2003. The participation of adult patients from 21 family physicians was solicited during consecutive consultation periods. A research nurse reviewed medical records and extracted the data regarding chronic illnesses. For each chronic condition, a severity rating was determined in accordance with the CIRS scoring guidelines. RESULTS The sample consisted of 320 men and 660 women. Overall, 9 of 10 patients had more than 1 chronic condition. The prevalence of having 2 or more medical conditions in the 18- to 44-year, 45- to 64-year, and 65-year and older age-groups was, respectively, 68%, 95%, and 99% among women and 72%, 89%, and 97% among men. The mean number of conditions and mean CIRS score also increased significantly with age. CONCLUSIONS Whether measured by simply counting the number of conditions or using the CIRS, the prevalence of multimorbidity is quite high and increases significantly with age in both men and women. Patients with multimorbidity seen in family practice represent the rule rather than the exception.

Is There Time for Management of Patients With Chronic Diseases in Primary Care

Abstract: PURPOSE Despite the availability of national practice guidelines, many patients fail to receive recommended chronic disease care. Physician time constraints in primary care are likely one cause. METHODS We applied guideline recommendations for 10 common chronic diseases to a panel of 2,500 primary care patients with an age-sex distribution and chronic disease prevalences similar to those of the general population, and estimated the minimum physician time required to deliver high-quality care for these conditions. The result was compared with time available for patient care for the average primary care physician. RESULTS Eight hundred twenty-eight hours per year, or 3.5 hours a day, were required to provide care for the top 10 chronic diseases, provided the disease is stable and in good control. We recalculated this estimate based on increased time requirements for uncontrolled disease. Estimated time required increased by a factor of 3. Applying this factor to all 10 diseases, time demands increased to 2,484 hours, or 10.6 hours a day. CONCLUSIONS Current practice guidelines for only 10 chronic illnesses require more time than primary care physicians have available for patient care overall. Streamlined guidelines and alternative methods of service delivery are needed to meet recommended standards for quality health care.

Interpersonal Continuity of Care and Care Outcomes: A Critical Review

Abstract: PURPOSE We wanted to undertake a critical review of the medical literature regarding the relationships between interpersonal continuity of care and the outcomes and cost of health care. METHODS A search of the MEDLINE database from 1966 through April 2002 was conducted by the primary author to fioriginal English language articles focusing on interpersonal continuity of patient care. The articles were then screened to select those articles focusing on the relationship between interpersonal continuity and the outcome or cost of care. These articles were systematically reviewed and analyzed by both authors for study method, measurement technique, and quality of evidence. RESULTS Forty-one research articles reporting the results of 40 studies were identifi ed that addressed the relationship between interpersonal continuity and care outcome. A total of 81 separate care outcomes were reported in these articles. Fifty-one outcomes were signifi cantly improved and only 2 were signifi cantly worse in association with interpersonal continuity. Twenty-two articles reported the results of 20 studies of the relationship between interpersonal continuity and cost. These studies reported signifi cantly lower cost or utilization for 35 of 41 cost variables in association with interpersonal continuity. CONCLUSIONS Although the available literature refl ects persistent methodologic problems, it is likely that a signifi cant association exists between interpersonal continuity and improved preventive care and reduced hospitalization. Future research in this area should address more specifi c and measurable outcomes and more direct costs and should seek to defi ne and measure interpersonal continuity more explicitly.

Patient-Centered Communication and Diagnostic Testing

Abstract: PURPOSE Although patient-centered communication is associated with improved health and patient trust, information about the impact of patient-centered communication on health care costs is limited. We studied the relationship between patient-centered communication and diagnostic testing expenditures. METHODS We undertook an observational cross-sectional study using covert standardized patient visits to study physician interaction style and its relationship to diagnostic testing costs. Participants were 100 primary care physicians in the Rochester, NY, area participating in a large managed care organization (MCO). Audio recordings of 2 standardized patient encounters for each physician were rated using the Measure of Patient-Centered Communication (MPCC). Standardized diagnostic testing and other expenditures, adjusted for patient demographics and case-mix, were derived from the MCO claims database. Analyses were adjusted for demographics and standardized patient detection. RESULTS Compared with other physicians, those who had MPCC scores in the lowest tercile had greater standardized diagnostic testing expenditures (11.0% higher, 95% confidence interval [CI], 4.5%–17.8%) and greater total standardized expenditures (3.5% higher, 95% CI, 1.0%–6.1%). Whereas lower MPCC scores were associated with shorter visits, adjustment for visit length and standardized patient detection did not affect the relationship with expenditures. Total (testing, ambulatory and hospital care) expenditures were also greater for physicians who had lower MPCC scores, an effect primarily associated with the effect on testing expenditures. CONCLUSIONS Patient-centered communication is associated with fewer diagnostic testing expenditures but also with increased visit length. Because costs and visit length may affect physicians’ and health systems’ willingness to endorse and practice a patient-centered approach, these results should be confirmed in future randomized trials.

Efficacy and tolerability of tricyclic antidepressants and SSRIs compared with placebo for treatment of depression in primary care: a meta-analysis.

Abstract: PURPOSE Depression is common in primary care. There are no systematic reviews of depression treatment comparing antidepressants with placebo; hence, we do not know whether these medications are effective in primary care. METHODS We searched the Cochrane Collaboration Depression, Anxiety and Neurosis Group register of controlled trials, MEDLINE, International Pharmaceuti- cal abstracts, PsycINFO, and EMBASE. Abstracts of potential studies were reviewed independently by 2 authors. Studies needed to include randomized controlled tri- als of either a tricyclic antidepressant (TCA) or selective serotonin reuptake inhibi- tor (SSRI), or both, and placebo in a primary care setting. The data and quality of the studies were extracted and assessed by 2 authors blind to the other's choice. Disagreements were resolved by discussion. The main outcome measures were the standardized mean difference and weighted mean difference of the fi nal mean depression scores, the relative risk of improvement, and the number withdrawing because of side effects. Pooling of results was done using Review Manager 4.2.2. RESULTS There were 10 studies in which TCAs were compared with placebo, 3 in which SSRIs were compared with placebo, and 2 with both compared with pla- cebo. One half of the studies were of low methodological quality, and nearly all studies were of short duration, typically 6 to 8 weeks. Pooled estimates of effi cacy data showed a relative risk of 1.26 (95% CI, 1.12-1.42) for improvement with TCAs compared with placebo; For SSRIs, relative risk was 1.37 (95% CI, 1.21- 1.55). Most patients, 56% to 60%, responded well to active treatment compared with 42% to 47% for placebo. The number needed to treat for TCAs was about 4, and for SSRIs it was 6. The numbers needed to harm (for withdrawal caused by side effects) ranged from 5 to 11 for TCAs and 21 to 94 for SSRIs. Low-dose (100 mg or 75 mg) as well as high-dose TCAs were effective. CONCLUSION This systematic review is the fi rst comparing antidepressants with placebo for treatment of depression in primary care. Both TCAs and SSRIs are effective. This review is also the fi rst to show that low-dose TCAs are effective in primary care. Prescribing antidepressants in primary care is a more effective clini- cal activity than prescribing placebo.

The Meaning Of Healing: Transcending Suffering

Abstract: PURPOSE Medicine is traditionally considered a healing profession, but it has neither an operational definition of healing nor an explanation of its mechanisms beyond the physiological processes related to curing. The objective of this study was to determine a definition of healing that operationalizes its mechanisms and thereby identifies those repeatable actions that reliably assist physicians to promote holistic healing. METHODS This study was a qualitative inquiry consisting of in-depth, open-ended, semistructured interviews with Drs. Eric J. Cassell, Carl A. Hammerschlag, Thomas S. Inui, Elisabeth Kubler-Ross, Cicely Saunders, Bernard S. Siegel, and G. Gayle Stephens. Their perceptions regarding the definition and mechanisms of healing were subjected to grounded theory content analysis. RESULTS Healing was associated with themes of wholeness, narrative, and spirituality. Healing is an intensely personal, subjective experience involving a reconciliation of the meaning an individual ascribes to distressing events with his or her perception of wholeness as a person. CONCLUSIONS Healing may be operationally defined as the personal experience of the transcendence of suffering. Physicians can enhance their abilities as healers by recognizing, diagnosing, minimizing, and relieving suffering, as well as helping patients transcend suffering.

Adherence to Maintenance-Phase Antidepressant Medication as a Function of Patient Beliefs About Medication

Abstract: PURPOSE This study aimed to identify the demographic, psychiatric, and attitudinal predictors of treatment adherence during the maintenance phase of antidepressant treatment, ie, after symptoms and regimen are stabilized. METHODS We surveyed 81 primary care patients given maintenance antidepressant medications regarding general adherence, recent missed doses, depression and treatment features, medication beliefs (necessity, concerns, harmfulness, and overprescription), and other variables. Additional data were collected from medical and payer records. RESULTS Median treatment duration was 75 weeks. Adherence and beliefs were broadly dispersed and unrelated to treatment duration and type, physical functioning, and demographics. Multivariate analysis adjusting for social desirability, depression severity, and treatment duration indicated that an antidepressant-specific “necessity-minus-concerns” composite was strongly associated with both adherence outcomes. Specifically, adherence was highest when necessity exceeded concerns and lowest when concerns exceeded necessity. We crossed these 2 dimensions to characterize 4 patient attitudes toward antidepressants: skepticism, indifference, ambivalence, and acceptance. CONCLUSIONS Patients given maintenance antidepressants vary widely in adherence. This variation is primarily explained by the balance between their perceptions of need and harmfulness of antidepressant medication, in that adherence is lowest when perceived harm exceeds perceived need, and highest when perceived need exceeds perceived harm. We speculate on ways to tailor adherence strategies to patient beliefs. Subsequent research should determine whether patients’ perceptions about medication predict depression outcomes, can be used to improve clinical management, and respond to behavioral intervention.

Primary Care Practice-Based Research Networks: Working at the Interface Between Research and Quality Improvement

Abstract: PURPOSE We wanted to describe the emerging role of primary care practice-based in research, quality improvement (QI), and translation of research into practice (TRIP). METHODS We gathered information from the published literature, discussions with PBRN leaders, case examples, and our own personal experience to describe a role for PBRNs that comfortably bridges the gap between research and QI, discovery and application, academicians and practitioners—a role that may lead to the establishment of true learning communities. We provide specific recommendations for network directors, network clinicians, and other potential stakeholders. RESULTS PBRNs function at the interface between research and QI, an interface called TRIP by some members of the research community. In doing so, PBRNs are helping to clarify the difficulty of applying study findings to everyday care as an inappropriate disconnect between discovery and implementation, research and practice. Participatory models are emerging in which stakeholders agree on their goals; apply their collective knowledge, skills, and resources to accomplish these goals; and use research and QI methods when appropriate. CONCLUSIONS PBRNs appear to be evolving from clinical laboratories into learning communities, proving grounds for generalizable solutions to clinical problems, and engines for improvement of primary care delivery systems.

Changes in Age at Diagnosis of Type 2 Diabetes Mellitus in the United States, 1988 to 2000

Abstract: PURPOSE The prevalence of diabetes in the United States is increasing. There is also concern that diabetes may be occurring at a greater frequency in youth and in young adults. We describe US population trends in self-reported age at diagnosis of type 2 diabetes mellitus. METHODS We undertook a secondary analysis of data from the National Health and Nutrition Examination Survey (NHANES) 1999–2000 and NHANES III (1988–1994). Both surveys are stratified, multistage probability samples targeting the civilian, noninstitutionalized US population, which allow calculation of population estimates. We included adults aged 20 years and older. We compared self-reported age at diagnosis of type 2 diabetes between the 2 survey periods. RESULTS The mean age at diagnosis decreased from 52.0 to 46.0 years (P <.05). Racial and ethnic differences in age at diagnosis found in 1988 to 1994 are no longer found in 1999 to 2000. CONCLUSIONS The age at diagnosis of type 2 diabetes mellitus has decreased with time. This finding likely represents a combination of changing diagnostic criteria, improved physician recognition of diabetes, and increased public awareness. Younger age at diagnosis may also reflect a true population trend of earlier onset of type 2 diabetes.

Prehypertension and cardiovascular morbidity.

Abstract: PURPOSE The Seventh Report of the Joint National Commission (JNC 7) on High Blood Pressure established prehypertension (120 to 139 mm Hg systolic or 80 to 89 mm Hg diastolic) as a new risk category. We aim to determine the risk of major cardiovascular events associated with blood pressure in the prehypertensive range in a longitudinal, population-based cohort. METHODS Analyses were conducted on participants in the National Health and Nutrition Examination Survey I (1971–1975) observed for 18 years for major cardiovascular disease events. Cox proportional hazard ratios were calculated to assess relative risk of cardiovascular disease, including stroke, myocardial infarction, and heart failure, in participants with prehypertension and normal blood pressure (<120/80 mm Hg). RESULTS Prehypertension was associated with increased risk for cardiovascular disease (1.79 [95% confidence interval (CI) 1.40–2.24]) in unadjusted analysis. After adjustment for cardiovascular risk factors, the relationship of prehypertension to cardiovascular disease was diminished but persisted (1.32 [95% CI 1.05–1.65]). Ninety-three percent of prehypertensive individuals had at least 1 cardiovascular risk factor. Low prehypertension (120–129/80–84 mm Hg) was associated with increased cardiovascular disease in unadjusted analyses (1.56 [95% CI 1.23–1.98]) but was not statistically significant in adjusted analyses (1.24 [95% CI 0.96–1.59]). High-normal blood pressure (130–139/85–89 mm Hg) remained a predictor of cardiovascular disease in unadjusted (2.13 [95% CI 1.64–2.76]) and adjusted (1.42 [95% CI 1.09–1.84]) analyses. CONCLUSIONS In a longitudinal, population-based, US cohort, prehypertension was associated with increased risk of major cardiovascular events independently of other cardiovascular risk factors. These findings, along with the presence of cardiovascular risk factors in the majority of participant sample with prehypertension, support recommendations for physicians to actively target lifestyle modifications and multiple risk reduction in their prehypertensive patients.

Do Patients Treated With Dignity Report Higher Satisfaction, Adherence, and Receipt of Preventive Care?

Abstract: PURPOSE Although involving patients in their own health care is known to be associated with improved outcomes, this study was conducted to determine whether respecting persons more broadly, such as treating them with dignity, has additional positive effects. METHODS Using data from the Commonwealth Fund 2001 Health Care Quality Survey of 6,722 adults living in the United States, we performed survey-weighted logistic regression analysis to evaluate independent associations between 2 measures of respect (involvement in decisions and treatment with dignity) and patient outcomes (satisfaction, adherence, and receipt of optimal preventive care). Then we calculated adjusted probabilities of these outcomes and performed stratified analyses to examine results across racial/ethnic groups. RESULTS After adjustment for respondents’ demographic characteristics, the probability of reporting a high level of satisfaction was higher for those treated with dignity vs not treated with dignity (0.70 vs 0.38, P <.001) and for those involved in, versus not involved in, decisions (0.70 vs 0.39, P <.001). These associations were consistent across all racial/ethnic groups. Being involved in decisions was significantly associated with adherence for whites, whereas being treated with dignity was significantly associated with adherence for racial/ethnic minorities. The probability of receiving optimal preventive care was marginally greater for those treated with dignity (0.68 vs 0.63, P = .054), but did not differ with respect to involvement in decisions (0.67 vs 0.67, P = .95). CONCLUSIONS Being treated with dignity and being involved in decisions are independently associated with positive outcomes. Although involving patients in decisions is an important part of respecting patient autonomy, it is also important to respect patients more broadly by treating them with dignity.

Time Spent in Face-to-Face Patient Care and Work Outside the Examination Room

Abstract: PURPOSE Contrary to physicians' concerns that face-to-face patient time is decreasing, data from the National Ambulatory Medical Care Survey (NAMCS) indicate that between 1988 and 1998, durations of primary care outpatient visits have increased. This study documented how physicians spend time during the workday, including time outside the examination room, and compared observed face-to-face patient care time with that reported in NAMCS. METHODS Using time-motion study techniques, for each of 11 physicians, 2 patient care days were randomly selected and documented by direct observa- tion. Physician time spent on face-to-face patient care and 54 activities outside the examination room were documented. Data represent 12,180 minutes of work and 611 outpatient visits. RESULTS The average workday duration was 8.6 hours, and face-to-face patient care accounted for 55% of the day. Work outside the examination room relevant to a patient currently being seen averaged 14% of the day. Work related to a patient not physically present accounted for one fi fth (23%) of the workday. The combination of face-to-face time and time spent on visit-specifi c work outside the examination room assessed by direct observation was signifi cantly less than the 2003 NAMCS estimate of visit duration assessed by physician report (13.3 vs 18.7 minutes, P <.001). CONCLUSIONS Nearly one half of a primary care physician's workday is spent on activities outside the examination room, predominately focused on follow-up and documentation of care for patients not physically present. National estimates of visit duration overestimate the combination of face-to-face time and time spent on visit-specifi c work outside the examination room by 41%.

Comorbidity and the use of primary care and specialist care in the elderly.

Abstract: PURPOSE The impact of comorbidity on use of primary care and specialty services is poorly understood. The purpose of this study was to determine the relationship between morbidity burden, comorbid conditions, and use of primary care and specialist services METHODS The study population was a 5% random sample of Medicare beneficiaries, taken from 1999 Medicare files. We analyzed the number of ambulatory face-to-face patient visits to primary care physicians and specialists for each diagnosis, with each one first considered as the “main” one and then as a comorbid diagnosis to another. Each patient was categorized by extent of total morbidity burden using the Johns Hopkins Adjusted Clinical Group case-mix system. RESULTS Higher morbidity burden was associated with more visits to specialists, but not to primary care physicians. Patients with most diagnoses had more visits, both to primary care and specialist physicians for comorbid diagnoses than for the main diagnosis itself. Although patients, especially those with high morbidity burdens, generally made more visits to specialists than to primary care physicians, this finding was not always the case. For patients with 66 diagnoses, primary care visits for those diagnoses exceeded specialist visits in all morbidity burden groups; for patients with 87 diagnoses, specialty visits exceeded primary care visits in all morbidity burden groups. CONCLUSION In the elderly, a high morbidity burden leads to higher use of specialist physicians, but not primary care physicians, even for patients with common diagnoses not generally considered to require specialist care. This finding calls for a better understanding of the relative roles of generalists and specialists in the US health services system.

Breast and Cervical Cancer Screening: Impact of Health Insurance Status, Ethnicity, and Nativity of Latinas

Abstract: PURPOSE Although rates of cancer screening for Latinas are lower than for non-Latina whites, little is known about how insurance status, ethnicity, and nativity interact to influence these disparities. Using a large statewide database, our study examined the relationship between breast and cervical cancer screening rates and socioeconomic and health insurance status among foreign-born Latinas, US-born Latinas, and non-Latina whites in California. METHODS Data from the1998 California Women’s Health Survey (CWHS) were analyzed (n = 3,340) using multiple logistic regression models. Utilization rates of mammography, clinical breast examinations, and Papanicolaou (Pap) smear screening among foreign-born Latinas, US-born Latinas, and non-Latina whites were the outcome measures. RESULTS Foreign-born Latinas had the highest rates of never receiving mammography, clinical breast examinations, and Pap smears (21%, 24%, 9%, respectively) compared with US-born Latinas (12%, 11%, 7%, respectively) and non-Latina whites (9%, 5%, 2%, respectively). After controlling for socioeconomic factors, foreign-born Latinas were more likely to report mammography use in the previous 2 years and Pap smear in the previous 3 years than non-Latina whites. Lack of health insurance coverage was the strongest independent predictor of low utilization rates for mammography (odds ratio [OR] = 2.05; 95% confidence interval [CI], 1.53–2.76), clinical breast examinations (OR = 2.29; 95% CI, 1.80–2.90) and Pap smears (OR = 2.89; 95% CI, 2.17–3.85.) CONCLUSIONS Breast and cervical cancer screening rates vary by ethnicity and nativity, with foreign-born Latinas experiencing the highest rates of never being screened. After accounting for socioeconomic factors, differences by ethnicity and nativity are reversed or eliminated. Lack of health insurance coverage remains the strongest predictor of cancer screening underutilization.

The Break-Even Point: When Medical Advances Are Less Important Than Improving the Fidelity With Which They Are Delivered

Abstract: Society invests billions of dollars in the development of new drugs and technologies but comparatively little in the fidelity of health care, that is, improving systems to ensure the delivery of care to all patients in need. Using mathematical arguments and a nomogram, we demonstrate that technological advances must yield dramatic, often unrealistic increases in efficacy to do more good than could be accomplished by improving fidelity. In 2 examples (the development of anti-platelet agents and statins), we show that enhanced efficacy failed to achieve the health gains that would have occurred by delivering older agents to all eligible patients. Society’s huge investment in technological innovations that only modestly improve efficacy, by consuming resources needed for improved delivery of care, may cost more lives than it saves. The misalignment of priorities is driven partly by the commercial interests of industry and by the public’s appetite for technological breakthroughs, but health outcomes ultimately suffer. Health, economic, and moral arguments make the case for spending less on technological advances and more on improving systems for delivering care.

Patients’ Beliefs About Racism, Preferences for Physician Race, and Satisfaction With Care

Abstract: PURPOSE Few studies have attempted to link patients’ beliefs about racism in the health care system with how they use and experience health care. METHODS Using telephone survey data from a national sample of 1,479 whites, 1,189 African Americans, and 983 Latinos, we explored patients’ beliefs about racism, their preferences for the race and ethnicity of their physician, and their satisfaction with that physician. A scale was developed to reflect patients’ beliefs about racism. Race-stratified analyses assessed associations between patients’ beliefs, racial preferences for physicians, choice of physician, and satisfaction with care. RESULTS Among African Americans, stronger beliefs about racial discrimination in health care were associated with preferring an African American physician (P <.001). Whereas only 22% of African Americans preferred an African American physician, those who preferred a African American physician and had an African American physician were more likely to rate their physician as excellent than did African Americans who preferred a African American physician but had a non–African American physician (57% vs 20%, P <.001). Latinos with stronger beliefs about discrimination in health care were more likely to prefer a Latino physician (P <.001). One third of Latinos preferred a Latino physician. Though not statistically significant, those who preferred and had a Latino physician rated their physician higher than Latinos who preferred a Latino physician but had a non-Latino physician (40% vs 29%). CONCLUSIONS Many African Americans and Latinos perceive racism in the health care system, and those who do are more likely to prefer a physician of their own race or ethnicity. African Americans who have preferences are more often satisfied with their care when their own physicians match their preferences.

Practical and relevant self-report measures of patient health behaviors for primary care research.

Abstract: PURPOSE With increasing evidence for the value of behavior change counseling, there is a need for health behavior measurements that can be implemented in primary care research. This article discusses criteria for and reviews self-report measures to briefly assess cigarette smoking, eating patterns, physical activity, and risky drinking across the life course. It then proposes pragmatic measures for use in practice-based research. METHODS Drawing from literature reviews, previous multisite studies, personal communications with experts in the field, and guidance from an expert panel, we identified self-report behavior change measures and gave priority to items that addressed Healthy People 2010 goals, as well as those that were practical (ie, shorter, and easier to score and use for intervention), were sensitive to change, and produced results that could directly inform primary care intervention. RESULTS Separate recommendations are described for measures for adults and for children/adolescents. We recommend a set of 22 items for adults and 16 items for adolescents to track succinctly their status on the 4 health behaviors above. Perfected measures remain elusive: newly developed measures of physical activity and eating patterns are recommended, and in general, the brief measures for adults are currently better validated than are the child measures. CONCLUSIONS A set of totally satisfactory practical instruments for measuring behavior change in primary care settings does not yet exist. There is sufficient progress to encourage use of and further research on the proposed items. Use of a common set of items across different interventions and projects will help to advance clinical and behavioral research in primary care settings.

Impact of an Electronic Medical Record on Diabetes Quality of Care

Abstract: PURPOSE This study was designed to evaluate the impact of electronic medical record (EMR) implementation on quality of diabetes care. METHODS We conducted a 5-year longitudinal study of 122 adults with diabe- tes mellitus at an intervention (EMR) clinic and a comparison (non-EMR) clinic. Clinics had similarly trained primary care physicians, similar patient populations, and used a common diabetes care guideline that emphasized the importance of glucose control. The EMR provided basic decision support, including prompts and reminders for diabetes care. Preintervention and postintervention frequency of testing for glycated hemoglobin (HbA1c) and low-density lipoprotein (LDL) levels were compared with and without adjustment for patient age, sex, comorbidity, and baseline HbA1c level. RESULTS Frequency of HbA1c tests increased at the EMR clinic compared with the frequency at the non-EMR clinic (P <.001). HbA1c levels improved in both clinics (P <.05) with no signifi cant differences between clinics 2 years (P = .10) or 4 years (P = .27) after EMR implementation. Similar results were observed for LDL levels. CONCLUSIONS In this controlled study, EMR use led to an increased number of HbA1c and LDL tests but not to better metabolic control. If EMRs are to fulfi ll their promise as care improvement tools, improved implementation strategies and more sophisticated clinical decision support may be needed.

Social Network Analysis as an Analytic Tool for Interaction Patterns in Primary Care Practices

Abstract: PURPOSE Social network analysis (SNA) provides a way of quantitatively analyzing relationships among people or other information-processing agents. Using 2 practices as illustrations, we describe how SNA can be used to characterize and compare communication patterns in primary care practices. METHODS Based on data from ethnographic field notes, we constructed matrices identifying how practice members interact when practice-level decisions are made. SNA software (UCINet and KrackPlot) calculates quantitative measures of network structure including density, centralization, hierarchy and clustering coefficient. The software also generates a visual representation of networks through network diagrams. RESULTS The 2 examples show clear distinctions between practices for all the SNA measures. Potential uses of these measures for analysis of primary care practices are described. CONCLUSIONS SNA can be useful for quantitative analysis of interaction patterns that can distinguish differences among primary care practices.

Beliefs and Attitudes Associated With the Intention to Not Accept the Diagnosis of Depression Among Young Adults

Abstract: PURPOSE Negative attitudes and beliefs about depression treatment may prevent many young adults from accepting a diagnosis and treatment for depression. We undertook a study to determine the association between depressive symptom severity, beliefs about and attitudes toward treatment, subjective social norms, and past behavior on the intent not to accept a physician’s diagnosis of depression. METHODS We conducted a cross-sectional study of 10,962 persons aged 16 to 29 years who participated and had positive screening results on the Center for Epidemiologic Studies Depression (CES-D) score in an Internet-based public health depression screening program. Participants reported whether they would accept their physician’s diagnosis of depression. Based on the theory of reasoned action, we developed a multivariate model of the factors that predict intent not to accept a diagnosis of depression. RESULTS Twenty-six percent of the participants stated their intent not to accept their physician’s diagnosis of depression. Disagreeing that medications are effective in treating depression (strongly disagree, odds ratio ( OR ) = 6.5, 95% confidence interval (CI), 4.6–9.3), that there is a biological cause for depression (strongly disagree, OR = 1.9, 95% CI, 1.3–2.7), and agreeing that you would be embarrassed if your friends knew you had depression were associated with the intent not to accept a diagnosis of depression (strongly agree, OR = 2.3, 95% CI, 1.8–2.9). Beliefs and attitudes, subjective social norms, and past behavior explained most of the variance in this model (84%). CONCLUSIONS Negative beliefs and attitudes, subjective social norms, and lack of past helpful treatment experiences are associated with the intent to not accept the diagnosis of depression and may contribute to low rates of treatment among young adults.

Continuity of Care: Is the Personal Doctor Still Important? A Survey of General Practitioners and Family Physicians in England and Wales, the United States, and the Netherlands

Abstract: PURPOSE We determined the reported value general practitioners/family physicians in 3 different health care systems place on the various types of continuity of care. METHODS We conducted a postal questionnaire survey in England and Wales, the United States, and the Netherlands. The participants were 1,523 general practitioners/family physicians (568 from England and Wales, 453 from the United States and 502 from the Netherlands). Our main outcome measures were the perceived importance of the types of continuity of care and doctor or practice characteristics that may influence attitudes toward personal continuity of care. RESULTS The response rates were England and Wales 60% (568/946), United States 47% (453/963) and Netherlands 76% (502/660). The doctors in all 3 countries felt strongly that personal continuity remained an important aspect of good-quality care to their patients. Within a given health care system, doctors’ personal and practice characteristics explained only a small part of the variance in attitudes toward the provision of personal continuity of care (England and Wales and the Netherlands r2 = 0.04, United States r2 = 0.01). The doctors in all 3 countries felt that they were currently able to provide all 3 types of continuity of care, although doctors in England and Wales were least positive about the provision of informational and management continuity across the primary-secondary care divide. CONCLUSIONS General practitioners/family physicians from 3 differing health care systems all place high value on being able to provide personal continuity of care to patients. Personal continuity of care remains a core value of general practice/family medicine and should be taken account of by policy makers when redesigning health care systems.

Delivery of clinical preventive services in family medicine offices.

Abstract: BACKGROUND This study aimed to elucidate how clinical preventive services are delivered in family practices and how this information might inform improvement efforts. METHODS We used a comparative case study design to observe clinical preventive service delivery in 18 purposefully selected Midwestern family medicine offices from 1997 to 1999. Medical records, observation of outpatient encounters, and patient exit cards were used to calculate practice-level rates of delivery of clinical preventive services. Field notes from direct observation of clinical encounters and prolonged observation of the practice and transcripts from in-depth interviews of practice staff and physicians were systematically examined to identify approaches to delivering clinical preventive services recommended by the US Preventive Services Task Force. RESULTS Practices developed individualized approaches for delivering clinical preventive services, with no one approach being successful across practices. Clinicians acknowledged a 3-fold mission of providing acute care, managing chronic problems, and prevention, but only some made prevention a priority. The clinical encounter was a central focus for preventive service delivery in all practices. Preventive services delivery rates often appeared to be influenced by competing demands within the clinical encounter (including between different preventive services), having a physician champion who prioritized prevention, and economic concerns. CONCLUSIONS Practice quality improvement efforts that assume there is an optimal approach for delivering clinical preventive services fail to account for practices’ propensity to optimize care processes to meet local contexts. Interventions to enhance clinical preventive service delivery should be tailored to meet the local needs of practices and their patient populations.

'Coming down the line'-- patients' understanding of their family history of common chronic disease.

Abstract: PURPOSE The family history is becoming an increasingly important feature of health promotion and early detection of common chronic diseases in primary care. Previous studies of patients from genetics clinics suggest a divergence between how persons with a family history perceive and understand their risk and the risk information provided by health professionals. This interview study aimed to explore how patients in primary care understand and come to terms with their family history of cancer, heart disease, or diabetes and how family history might affect consultations about disease risk and management.

Screening for Gonorrhea: Recommendation Statement

Abstract: The U.S. Preventive Services Task Force (USPSTF) recommends that clinicians screen all sexually active women, including those who are pregnant, for gonorrhea infection if they are at increased risk for infection (that is, if they are young or have other individual or population risk factors; see

Cost-Effectiveness of Enhancing Primary Care Depression Management on an Ongoing Basis

Abstract: PURPOSE Although potentially costly, enhancing primary care depression management on an ongoing basis results in substantial long-term treatment effectiveness. The purpose of this article is to compare the cost-effectiveness of this approach with that of usual care. METHODS The study was conducted in 12 community primary care practices randomized to enhanced or usual care after stratification by baseline practice patterns. Practices assigned to enhanced care encouraged depressed patients to engage in active treatment, using practice nurses to provide regularly scheduled care management during the course of 24 months. We analyze outcomes for 211 adults (73.4% of potential eligible patients) beginning a new treatment episode for major depression determined by previsit screening. Outcomes included blinded estimates of days free of depression impairment as well as health care costs for 2 years. RESULTS Enhanced care significantly increased the number of days free of depression impairment for 2 years when compared with usual care (647.6 days vs 588.2 days, P <.01). The incremental cost-effectiveness ratio for enhanced care ranged from $9,592 to $14,306 per quality-adjusted life-year (QALY). The number of incremental days free of depression impairment increased between the first year and the second year (23.0 vs 36.4, respectively, P <.001) while incremental health plan costs decreased significantly ($568 vs -$12, P <.001). CONCLUSIONS Enhancing primary care depression management on an ongoing basis should be considered for adoption by policy and health plan leaders.

Implementing an Electronic Medical Record in a Family Medicine Practice: Communication, Decision Making, and Conflict

Abstract: PURPOSE Electronic medical record (EMR) systems offer substantial opportunities to organize and manage clinical data in ways that can potentially improve preventive health care, the management of chronic illness, and the financial health of primary care practices. The functionality of EMRs as implemented, however, can vary substantially from that envisaged by their designers and even from those who purchase the programs. The purpose of this study was to explore how unique aspects of a family medicine office culture affect the initial implementation of an EMR. METHODS As part of a larger study, we conducted a qualitative case study of a private family medicine practice that had recently purchased and implemented an EMR. We collected data using participant observation, in-depth interviews, and key informant interviews. After the initial data collection, we shared our observations with practice members and returned 1 year later to collect additional data. RESULTS Dysfunctional communication patterns, the distribution of formal and informal decision-making power, and internal conflicts limited the effective implementation and use of the EMR. The implementation and use of the EMR made tracking and monitoring of preventive health and chronic illness unwieldy and offered little or no improvement when compared with paper charts. CONCLUSIONS Implementing an EMR without an understanding of the systemic effects and communication and the decision-making processes within an office practice and without methods for bringing to the surface and addressing conflicts limits the opportunities for improved care offered by EMRs. Understanding how these common issues manifest within unique practice settings can enhance the effective implementation and use of EMRs.

Physicians Answer More Clinical Questions and Change Clinical Decisions More Often With Synthesized Evidence: A Randomized Trial in Primary Care

Abstract: PURPOSE Clinicians need evidence in a format that rapidly answers their questions. DynaMed is a database of synthesized evidence. We investigated whether primary care clinicians would answer more clinical questions, change clinical decision making, and alter search time using DynaMed in addition to their usual information sources. METHODS Fifty-two primary care clinicians naive to DynaMed searched for answers to 698 of their own clinical questions using the Internet. On a per-question basis, participants were randomized to have access to DynaMed (A) or not (N) in addition to their usual information sources. Outcomes included proportions of questions answered, proportions of questions with answers that changed clinical decision making, and median search times. The statistical approach of per-participant analyses of clinicians who asked questions in both A and N states was decided before data collection. RESULTS Among 46 clinicians in per-participant analyses, 23 (50%) answered a greater proportion of questions during A than N, and 13 (28.3%) answered more questions during N than A (P = .05). Finding answers that changed clinical decision making occurred more often during A (25 clinicians, 54.3%) than during N (13 clinicians, 28.3%) (P = .01). Search times did not differ significantly. Overall, participants found answers for 263 (75.8%) of 347 A questions and 250 (71.2%) of 351 N questions. Answers changed clinical decision making for 224 (64.6%) of the A questions and 209 (59.5%) of the N questions. CONCLUSIONS Using DynaMed, primary care clinicians answered more questions and changed clinical decisions more often, without increasing overall search time. Synthesizing results of systematic evidence surveillance is a feasible method for meeting clinical information needs in primary care.

Prescription for Health: Changing Primary Care Practice to Foster Healthy Behaviors

Abstract: PURPOSE The leading causes of premature death in the United States are linked to 4 behaviors: smoking, unhealthy diet, physical inactivity, and risky alcohol use. We report lessons from 17 exploratory projects funded under Prescription for Health that tested the feasibility of innovative behavior change strategies for at least 2 of these behaviors in primary care practices. METHODS Seventeen practice-based research networks (PBRNs) implemented and evaluated tools, cues, and techniques in 120 family medicine, internal medicine, pediatric, and nursing practices across an ethnically diverse sample of adults, children, and adolescents in rural and urban settings. We reviewed progress reports and notes from site visits and 3 meetings to generate overarching lessons. RESULTS PBRNs successfully implemented their projects in diverse practices despite reported logistical challenges and practice constraints. The networks showed that distributing the effort across the care team and throughout the practice and community is possible. Although each behavior required specific attention, each did not require its own separate staff and system. Three models emerged as helpful guides for the comprehensive redesign of health behavior counseling, but they require adaptation for use in real-world primary care settings. Traditional methods of collaboration yielded mixed results, making obvious a need for dedicated collaboration funds and a better framework to identify and align high-yield opportunities. CONCLUSIONS These projects confirm the feasibility of health behavior counseling in primary care practice. They also highlight the need for substantive practice redesign, and the value of models and frameworks to guide redesign and collaborative efforts.

Metformin as Treatment for Overweight and Obese Adults: A Systematic Review

Abstract: PURPOSE We wanted to determine whether metformin is an effective medication for treatment of overweight or obese adults who do not have diabetes mellitus or polycystic ovary syndrome (PCOS). METHODS We searched MEDLINE (1966–2003), EMBASE (1986–2003), Allied and Complementary Medicine Database (1985–2003), International Pharmaceutical Abstracts (1970–2003), the Cochrane Library, American College of Physicians Journal Club, Database of Abstracts of Reviews of Effects, Cochrane Controlled Trials Register, MEDLINE In-Process & Other Non-Indexed Citations, reference lists of retrieved articles, and articles by selected authors and pharmaceutical manufacturers. Inclusion criteria were being obese or overweight determined by a BMI of 25 kg/m2 or greater or waist-to-hip ratio (WHR) of more than 0.8, metformin use, and aged 18 years or older. Exclusion criteria were a diagnosis of diabetes mellitus, polycystic ovarian syndrome or descriptors of polycystic ovarian syndrome, human immunodeficiency virus infection, and concomitant antipsychotic medications. Trials were graded on an 11-point Jadad scale. Only randomized controlled and blinded trials were accepted. Two reviewers independently extracted data from each trial. Primary outcomes measured were changes in BMI, WHR, and weight. RESULTS Fifty-seven potentially relevant studies were initially identified; 48 were excluded because of lack of randomization, lack of blinding, failure to meet inclusion or exclusion criteria, inaccessible outcomes, or improper study design. Nine clinical trials met criteria for validity assessment. Four studies used the parameter of waist-to-hip ratio, 3 studies included BMI, and 8 used weight. Two of the 9 studies showed a small reduction in WHR. CONCLUSION Insufficient evidence exists for the use of metformin as treatment of overweight or obese adults who do not have diabetes mellitus or polycystic ovary syndrome. Further studies are needed to answer this clinical question.
