admission. This proportion could already be greater in some parts of the country and may increase if referrals of cases of self-poisoning increase faster than the facilities for their assessment and management. The provision of social work and psychiatric expertise in casualty departments may be one means of preventing unnecessary medical admissions without risk to the patients. Dr Blake's and Dr Bramble's figures do not demonstrate, however, that any advantage would attach to medical teams taking over assessment from psychiatrists except that, by implication, assessments would be completed sooner by staff working on the ward full time. What the figures actually suggest is that if assessment of overdoses were left to house doctors there would be an increase in admissions to psychiatric units (by 19°U), outpatients (by 5O°'), and referrals to social services (by 140o). So for house doctors to assess overdoses would provide no economy for the psychiatric or social services. The study does not tell us what the consequences would have been for the six patients who the psychiatrists would have admitted but to whom the house doctors would have offered outpatient appointments.

NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines

Purpose To update the International Society of Geriatric Oncology (SIOG) 2005 recommendations on geriatric assessment (GA) in older patients with cancer. Methods SIOG composed a panel with expertise in geriatric oncology to develop consensus statements after literature review of key evidence on the following topics: rationale for performing GA; findings from a GA performed in geriatric oncology patients; ability of GA to predict oncology treatment–related complications; association between GA findings and overall survival (OS); impact of GA findings on oncology treatment decisions; composition of a GA, including domains and tools; and methods for implementing GA in clinical care. Results GA can be valuable in oncology practice for following reasons: detection of impairment not identified in routine history or physical examination, ability to predict severe treatment-related toxicity, ability to predict OS in a variety of tumors and treatment settings, and ability to influence treatment choice and intensit...

International Society of Geriatric Oncology Consensus on Geriatric Assessment in Older Patients With Cancer

Purpose During the last decade, oncologists and geriatricians have begun to work together to integrate the principles of geriatrics into oncology care. The increasing use of a comprehensive geriatric assessment (CGA) is one example of this effort. A CGA includes an evaluation of an older individual's functional status, comorbid medical conditions, cognition, nutritional status, psychological state, and social support; and a review of the patient's medications. This article discusses recent advances on the use of a CGA in older patients with cancer. Methods In this article, we provide an update on the studies that address the domains of a geriatric assessment applied to the oncology patient, review the results of the first studies evaluating the use of a CGA in developing interventions to improve the care of older adults with cancer, and discuss future research directions. Results The evidence from recent studies demonstrates that a CGA can predict morbidity and mortality in older patients with cancer. Acc...

Comprehensive Geriatric Assessment for Older Patients With Cancer

BACKGROUND
Hypovitaminosis D and a low calcium intake contribute to increased parathyroid function in elderly persons. Calcium and vitamin D supplements reduce this secondary hyperparathyroidism, but whether such supplements reduce the risk of hip fractures among elderly people is not known.


METHODS
We studied the effects of supplementation with vitamin D3 (cholecalciferol) and calcium on the frequency of hip fractures and other nonvertebral fractures, identified radiologically, in 3270 healthy ambulatory women (mean [+/- SD] age, 84 +/- 6 years). Each day for 18 months, 1634 women received tricalcium phosphate (containing 1.2 g of elemental calcium) and 20 micrograms (800 IU) of vitamin D3, and 1636 women received a double placebo. We measured serial serum parathyroid hormone and 25-hydroxyvitamin D (25(OH)D) concentrations in 142 women and determined the femoral bone mineral density at base line and after 18 months in 56 women.


RESULTS
Among the women who completed the 18-month study, the number of hip fractures was 43 percent lower (P = 0.043) and the total number of nonvertebral fractures was 32 percent lower (P = 0.015) among the women treated with vitamin D3 and calcium than among those who received placebo. The results of analyses according to active treatment and according to intention to treat were similar. In the vitamin D3-calcium group, the mean serum parathyroid hormone concentration had decreased by 44 percent from the base-line value at 18 months (P < 0.001) and the serum 25(OH)D concentration had increased by 162 percent over the base-line value (P < 0.001). The bone density of the proximal femur increased 2.7 percent in the vitamin D3-calcium group and decreased 4.6 percent in the placebo group (P < 0.001).


CONCLUSIONS
Supplementation with vitamin D3 and calcium reduces the risk of hip fractures and other nonvertebral fractures among elderly women.

Vitamin D and Calcium to Prevent Hip Fractures in Elderly Women

OBJECTIVES: To examine the proportion of time spent in three levels of mobility (lying, sitting, and standing or walking) by a cohort of hospitalized older veterans as measured by validated wireless accelerometers.

DESIGN: A prospective, observational cohort study.

SETTING: One hundred fifty–bed Department of Veterans Affairs hospital.

PARTICIPANTS: Forty-five hospitalized medical patients, aged 65 and older who were not delirious, did not have dementia, and were able to walk in the 2 weeks before admission were eligible.

MEASUREMENTS: Wireless accelerometers were attached to the thigh and ankle of patients for the first 7 days after admission or until hospital discharge, whichever came first. The mean proportion of time spent lying, sitting, and standing or walking was determined for each hour after hospital admission using a previously validated algorithm.

RESULTS: Forty-five male patients (mean age 74.2) with a mean length of stay of 5.1 days generated 2,592 one-hour periods of data. A baseline functional assessment indicated that 35 (77.8%) study patients were willing and able to walk a short distance independently. No patient remained in bed the entire measured hospital stay, but on average, 83% of the measured hospital stay was spent lying in bed. The average amount of time that any one individual spent standing or walking ranged from a low of 0.2% to a high of 21%, with a median of 3%, or 43 minutes per day.

CONCLUSION: This is the first study to continuously monitor mobility levels early during a hospital stay. On average, older hospitalized patients spent most of their time lying in bed, despite an ability to walk independently.

The Underrecognized Epidemic of Low Mobility During Hospitalization of Older Adults

The purpose of the research was to demonstrate that comorbid health conditions disproportionately affect elderly cancer patients. Descriptive analyses and stacked area charts were used to examine the prevalence and severity of comorbid ailments by age of 27,506 newly diagnosed patients treated at one of eight cancer centers between 1998 and 2003. Hypertension was the most common ailment in all patients, diabetes was the second most prevalent ailment in middle-aged patients, and previous solid tumor(s) were the second most prevalent ailment in patients aged 74 and older. Although the prevalence and severity of comorbid ailments including dementia and congestive heart failure increased with age, some comorbidities such as HIV/AIDS and obesity decreased. Advances in cancer interventions have increased survivorship, but the impact of the changing prevalence and severity of comorbidities at different ages has implications for targeted research into targeted clinical and psychosocial interventions.

The changing prevalence of comorbidity across the age spectrum.

Importance Mobility limitations are common in older adults, affecting the physical, psychological, and social aspects of an older adult’s life. Objective To identify mobility risk factors, screening tools, medical management, need for physical therapy, and efficacy of exercise interventions for older primary care patients with limited mobility. Evidence Acquisition Search of PubMed and PEDro from January 1985 to March 31, 2013, using the search terms mobility limitation , walking difficulty , and ambulatory difficulty to identify English-language, peer-reviewed systematic reviews, meta-analyses, and Cochrane reviews assessing mobility limitation and interventions in community-dwelling older adults. Articles not appearing in the search referenced by reviewed articles were also evaluated. Findings The most common risk factors for mobility impairment are older age, low physical activity, obesity, strength or balance impairment, and chronic diseases such as diabetes or arthritis. Several tools are available to assess mobility in the ambulatory setting. Referral to physical therapy is appropriate, because physical therapists can assess mobility limitations and devise curative or function-enhancing interventions. Relatively few studies support therapeutic exercise to improve mobility limitation. Strong evidence supports resistance and balance exercises for improving mobility-limiting physical weakness and balance disorders. Assessing a patient’s physical environment and the patient’s ability to adapt to it using mobility devices is critical. Conclusions and Relevance Identification of older adults at risk for mobility limitation can be accomplished through routine screening in the ambulatory setting. Addressing functional deficits and environmental barriers with exercise and mobility devices can lead to improved function, safety, and quality of life for patients with mobility limitations.

Mobility Limitation in the Older Patient: A Clinical Review

Purpose The goal of this study was to characterize an elderly population admitted to a novel Oncology–Acute Care for Elders (OACE) unit, determine the prevalence of functional dependencies and geriatric syndromes, and examine their suitability for an interdisciplinary model of care. Patients and Methods We conducted a retrospective review of 119 patients age 65 years or older who had a primary oncologic or hematologic diagnosis and were admitted to the OACE Unit. Standard geriatric screens were administered to assess mood, functional, and cognitive status. Demographic and medical data were compiled by review of patients' medical records. Results The mean age of the patients was 74.1 years (standard deviation, 5.9 years). The sample was predominantly white, of equal sex, had limitations in instrumental and basic activities of daily living, and a mean length of stay of 6 days. Geriatric syndromes detected by the OACE interdisciplinary team included cognitive impairment (dementia and/or delirium), depression...

Geriatric Syndromes in Elderly Patients Admitted to an Oncology–Acute Care for Elders Unit

Importance Providing high-quality care while containing cost is essential for the economic stability of our health care system. The United States is experiencing a rapidly growing elderly population. The Acute Care for Elders (ACE) unit interdisciplinary team model of care has been shown to improve outcomes in hospitalized older adults. The University of Alabama at Birmingham ACE unit incorporates evidence-based care processes. We hypothesized that the ACE model would also reduce costs. Objective To examine variable direct costs from an interdisciplinary ACE compared with a multidisciplinary usual care (UC) unit. Design Retrospective cohort study. Setting Tertiary care academic medical center. Participants Hospitalists' patients aged 70 years or older spending the entirety of their hospitalization in either the ACE or UC unit in fiscal year 2010. Main Outcome Measures Using administrative data, we analyzed variable direct costs for ACE and UC patients. We also conducted a subset analysis restricted to the 25 most common diagnosis related groups (DRGs) shared by ACE and UC patients. Generalized linear regression was used to estimate cost ratios and 95% confidence intervals adjusted for age, sex, comorbidity score, and case mix index (CMI). Results A total of 818 hospitalists' patients met inclusion criteria: 428 from the ACE and 390 from the UC unit. For this study group (all DRGs), the mean (SD) variable direct cost per patient was $2109 ($1870) for ACE and $2480 ($2113) for UC (P = .009). Adjusted cost ratios revealed significant cost savings for patients with low (0.82; 95% CI, 0.72-0.94) or moderate (0.74; 95% CI, 0.62-0.89) CMI scores; care was cost neutral for patients with high CMI scores (1.13; 95% CI, 0.93-1.37). Significantly fewer ACE patients than UC patients were readmitted within 30 days of discharge (7.9% vs 12.8%; P = .02). Subset analysis of the 25 most common DRGs revealed a significantly reduced mean (SD) variable direct cost per patient for ACE compared with UC patients ($1693 [$1063] vs $2138 [$1431]; P  Conclusions and Relevance The ACE unit team model reduces costs and 30-day readmissions. In an era when improving care processes while reducing costs is a vital objective for the Medicare program and our nation as a whole, the ACE model meets these goals.
