A comparision between responses from a propensity-weighted web survey and an identical RDD survey

Abstract: The authors conducted a large-scale survey about health care twice, once as a web and once as a random digit dialing (RDD) phone survey. The web survey used a statistical technique, propensity scoring, to adjust for selection bias. Comparing the weighted responses from both surveys, there were no significant response differences in 8 of 37 questions. Web survey responses were significantly more likely to agree with RDD responses when the question asked about the respondent's personal health (9 times more likely), was a factual question (9 times more likely), and only had two as opposed to multiple response categories (17 times more likely). For three questions, significant differences turned insignificant when adjacent categories of multicategory questions were combined. Factual questions tended to also be questions with two rather than multiple response categories. More study is needed to isolate the effects of these two factors more clearly.

The Differential Impact of PTSD and Depression on HIV Disease Markers and Adherence to HAART in People Living with HIV

Abstract: Despite high rates of comorbidity, research has typically focused on the independent impact of posttraumatic stress disorder (PTSD) and depression symptoms in people living with HIV (PLWH). The present study examined the independent and comorbid influence of PTSD and depression symptoms on medication adherence, CD4 cell counts, and viral load, over the course of 3 months in 57 PLWH (82% men, 54% Caucasian, 44% African American) recruited from a clinic or social service agency. Both PTSD and depressive symptoms predicted lower subsequent adherence. However, only depressive symptoms predicted lower CD4 counts and presence of a detectable viral load. Participants reporting symptoms consistent with diagnostic levels of comorbid PTSD and depression were less likely to adhere to HAART and were more likely to have a detectable viral load. These results highlight the influences of PTSD and depression on adherence and HIV disease markers, and underscore the importance of examining comorbid symptomatology in PLWH.

Overview of the Content of Health Supervision for Young Children: Reports From Parents and Pediatricians

Abstract: Objective. To describe the content of anticipatory guidance provided to parents of infants and toddlers and to identify primary areas of unmet need as reported by both parents and pediatricians. Methods. Parent data were obtained from the National Survey of Early Childhood Health, a nationally representative sample of parents of 2068 US children aged 4 to 35 months. Pediatrician data were obtained from the Periodic Survey of Fellows, a national survey of members of the American Academy of Pediatrics. Results. Parents and pediatricians tend to agree on the relative ranking of which topics are most frequently addressed. Parents and pediatricians both report that the traditional topics of preventive care—immunizations, feeding issues, and sleep patterns—are most frequently discussed, whereas topics that were more recently introduced into pediatric care related to developmental needs and family context are less commonly addressed. Parent-reported discussion of these topics include reading (discussed for 61% of children 19-35 months) and child care (discussed for 26% of children 19-35 months). Parent reports of some unmet need—defined as topics not discussed that the parent believes would have been helpful to them—affect 36% of children aged 4 to 9 months and 56% of children aged 10 to 35 months and are highest for the topics of discipline strategies and toilet training. Other specific areas of unmet need reported by at least 15% of parents are burn prevention, child care, reading, vocabulary development, and social development. Rates of unmet need vary with family characteristics and health system factors, including maternal education, race/ethnicity, and length of well-child visits. Conclusion. Parents and pediatricians report high rates of discussion on many topics that are critical to healthy development in the first years of life. They also identify areas of need that largely address health supervision on developmental topics. Findings indicate that additional research is needed to understand issues related to specific topic areas as well as the dynamics of personal and system factors that determine what is discussed.

Common and Costly Hospitalizations for Pediatric Mental Health Disorders

Abstract: BACKGROUND AND OBJECTIVES: Inpatient pediatric mental health is a priority topic for national quality measurement and improvement, but nationally representative data on the patients admitted or their diagnoses are lacking. Our objectives were: to describe pediatric mental health hospitalizations at general medical facilities admitting children nationally; to assess which pediatric mental health diagnoses are frequent and costly at these hospitals; and to examine whether the most frequent diagnoses are similar to those at free-standing children’s hospitals. METHODS: We examined all discharges in 2009 for patients aged 3 to 20 years in the nationally representative Kids’ Inpatient Database (KID) and in the Pediatric Health Information System (free-standing children’s hospitals). Main outcomes were frequency of International Classification of Diseases, Ninth Revision, Clinical Modification – defined mental health diagnostic groupings (primary and nonprimary diagnosis) and, using KID, resource utilization (defined by diagnostic grouping aggregate annual charges). RESULTS: Nearly 10% of pediatric hospitalizations nationally were for a primary mental health diagnosis, compared with 3% of hospitalizations at free-standing children’s hospitals. Predictors of hospitalizations for a primary mental health problem were older age, male gender, white race, and insurance type. Nationally, the most frequent and costly primary mental health diagnoses were depression (44.1% of all mental health admissions; $1.33 billion), bipolar disorder (18.1%; $702 million), and psychosis (12.1%; $540 million). CONCLUSIONS: We identified the child mental health inpatient diagnoses with the highest frequency and highest costs as depression, bipolar disorder, and psychosis, with substance abuse an important comorbid diagnosis. These diagnoses can be used as priority conditions for pediatric mental health inpatient quality measurement.
