Measures of functional disability typically contain items that reflect limitations in performing activities of daily living (ADLs) or instrumental activities of daily living (IADLs). Combining IADL and ADL items together in the same scale would provide enhanced range and sensitivity of measurement. This article presents psychometric justification for a combined ADL/IADL scale. Data come from 2,977 disabled respondents in the 1989 National Long-Term Care Survey. Respondents indicated whether they received human help on 7 ADL items; they also indicated whether they were unable to perform each of 9 IADL items due to health reasons. Factor analyses using tetrachoric correlations demonstrated that 15 of the 16 items reflected one major dimension. Item response theory (IRT) methods were used to calibrate the items; a one-parameter IRT model fit the data. Item calibrations showed that ADL and IADL items were not hierarchically related. Analyses showed that a simple sum of item responses could be used to derive a measure of functional disability. Implications of using a 15-item ADL/IADL scale for eligibility determination and for comparing groups are discussed.

Impairments in hearing and vision are common for those aged 65 and older, and severe impairments may result in dependencies in daily activities. This article presents a longitudinal analysis of the risk of dying, or experiencing increased dependency in activities of daily living (ADLs) or instrumental activities of daily living (IADLs) for persons with self-rated hearing and/or visual impairment. The data are from baseline and 1-year follow-up of the GAO-Cleveland study of 1,408 community-dwelling elders. Bivariate and multiple logistic regression analyses were performed. Vision impairments and, to a lesser extent, hearing impairments were found to be significant risk factors for functional decline. After adjustment for age, sex, and cognitive status, persons who were otherwise free of functional dependency at baseline but who had only vision impairment or both vision and hearing impairments were 2.5 and 3.5 times more likely to experience functional decline than were unimpaired elderly persons, respectively. Those similarly impaired, but with IADL disability, were 1.8 and 2.5 times more likely to experience functional decline than were unimpaired elderly. Policy implications of these findings are discussed.

Although there has been increased interest in using outcomes as measures of quality, few studies have shown a link between structure or process and outcomes. In this analysis, based on approximately 2,500 residents in 80 nursing homes in Rhode Island, multivariate models estimate which aspects of care are associated with resident outcomes after controlling for resident characteristics. Outcomes, measured over a 6-month period included death, functional decline, and functional improvement. Results suggest that higher staff levels and lower RN turnover were related to functional improvement. Facilities with high catheter use, low rates of skin care, and low participation in organized activities were associated with negative outcomes. Facilities with few private-pay residents were also associated with negative outcomes. Receipt of a serious federal citation was associated with improved outcomes. For-profit facilities appeared to be more efficient in use of resources.

OBJECTIVES:To systematically document the implementation, components, comparators, adherence, and effectiveness of published fall prevention approaches in U.S. acute care hospitals. DESIGN: Systematic review. Studies were identified through existing reviews, searching five electronic databases, screening reference lists, and contacting topic experts for studies published through August 2011. SETTING: U.S. acute care hospitals. PARTICIPANTS: Studies reporting in-hospital falls for intervention groups and concurrent (e.g., controlled trials) or historic comparators (e.g., before-after studies). INTERVENTION: Fall prevention interventions. MEASUREMENTS: Incidence rate ratios (IRR, ratio of fall rate postintervention or treatment group to the fall rate preintervention or control group) and ratings of study details. RESULTS: Fifty-nine studies met inclusion criteria. Implementation strategies were sparsely documented (17% not at all) and included staff education, establishing committees, seeking leadership support, and occasionally continuous quality improvement techniques. Most interventions (81%) included multiple components (e.g., risk assessments (often not validated), visual risk alerts, patient education, care rounds, bed-exit alarms, and postfall evaluations). Fifty-four percent did not report on fall prevention measures applied in the comparison group, and 39% neither reported fidelity data nor described adherence strategies such as regular audits and feedback to ensure completion of care processes. Only 45% of concurrent and 15% of historic control studies reported sufficient data to compare fall rates. The pooled postintervention incidence rate ratio (IRR) was 0.77 (95% confidence interval = 0.52-1.12, P = .17; eight studies; I 2 : 94%). Meta-regressions showed no systematic association between implementation intensity, intervention complexity, comparator information, or adherence levels and IRR. CONCLUSION: Promising approaches exist, but better reporting of outcomes, implementation, adherence, intervention components, and comparison group information is necessary to establish evidence on how hospitals can successfully prevent falls.

The Centers for Medicare and Medicaid Services no longer reimburses hospitals for in-hospital falls with trauma.1 As the U.S. population ages, fall prevention is more relevant than ever; older, frail individuals are more prone to falls, and the consequences of falls are more severe. 2,3Preventing falls in U.S. acute care hospitals poses particular challenges, given that patients are acutely ill and average only 4.9 days in the hospital. 4 This compressed acuity places a greater burden on staff to keep patients safe, so results from fall prevention interventions in longterm care facilities may not apply to acute care settings. Similarly, resu...

Hospital spending represents approximately one third of total national health spending, and the majority of hospital spending is by public payers. Elderly individuals with long-term care needs are at particular risk for hospitalization. While some hospitalizations are unavoidable, many are not, and there may be benefits to reducing hospitalizations in terms of health and cost. This article reviews the evidence from 55 peer-reviewed articles on interventions that potentially reduce hospitalizations from formal long-term care settings. The interventions showing the strongest potential are those that increase skilled staffing, especially through physician assistants and nurse practitioners; improve the hospital-to-home transition; substitute home health care for selected hospital admissions; and align reimbursement policies such that providers do not have a financial incentive to hospitalize. Much of the evidence is weak and could benefit from improved research design and methodology.

Comparisons of disability across sociodemographic groups need to take DIF into account. Future research should examine the causes of DIF and develop alternative question wordings that reduce DIF effects.
