The Nursing Home Physical Performance Test: A Secondary Data Analysis of Women in Long-Term Care Using Item Response Theory.

Background and Objectives: The Nursing Home Physical Performance Test (NHPPT) was developed to measure function among nursing home residents using sit-to-stand, scooping applesauce, face washing, dialing phone, putting on sweater, and ambulating tasks. Using item response theory, we explore its measurement characteristics at item level and opportunities for improvements. Research Design and Methods: We used data from long-term care women. We fitted a graded response model, estimated parameters, and constructed probability and information curves. We identified items to be targeted toward lower and higher functioning persons to increase the range of abilities to which the instrument is applicable. We revised the scoring by making sit-to-stand and sweater items harder and dialing phone easier. We examined changes to concurrent validity with activities of daily living (ADL), frailty, and cognitive function. Results: Participants were 86 years old, had more than three comorbidities, and a NHPPT of 19.4. All items had high discrimination and were targeted toward the lower middle range of performance continuum. After revision, sit-to-stand and sweater items demonstrated greater discrimination among the higher functioning and/or greater spread of thresholds for response categories. The overall test showed discrimination over a wider range of individuals. Concurrent validity correlation improved from 0.60 to 0.68 for instrumental ADL and explained variability (R2) from 22% to 36% for frailty. Discussion and Implications: NHPPT has good measurement characteristics at the item level. NHPPT can be improved, implemented in computerized adaptive testing, and combined with self-report for greater utility, but a definitive study is needed.

Service-Enriched Housing: The Staying at Home Program.

INTRODUCTION: The purpose of this research was to determine whether service-enriched housing (i.e., the Staying at Home [SAH] program) in publicly subsidized buildings for low-income older adults influenced resident outcomes. METHOD: Eleven elderly high-rise buildings were used. Seven buildings had the SAH program and four did not. Information was collected from resident questionnaires, housing managers data, and medical information. A total of 10 desired outcomes were proposed as part of SAH (e.g., health improvements, receive more non-institutional services, receive more preventive services, and be less likely to be institutionalized). Information was collected over the course of the SAH program every 6 months from December 2008 through June 2011. RESULTS: Overall, 736 surveys were completed by SAH program participants and 399 were completed by control group participants. Seven of the ten desired outcomes were achieved, and in 3 of the ten cases, no differences between the SAH group and control group were identified. The program was also beneficial with respect to cost savings. CONCLUSION: On the basis of these findings, the SAH program should be viewed as a success. In this case, service-enriched housing for elders in high-rise buildings would appear to be beneficial.

Achieving and sustaining high rates of influenza immunization among long-term care staff.

BACKGROUND: Influenza causes significant morbidity and mortality in long-term care facilities. Immunization of health care workers has been shown to reduce the impact of influenza in this setting, yet few studies address improvement efforts aimed at long-term care staff immunization. OBJECTIVE: To determine the feasibility of achieving and sustaining high rates of staff influenza immunization for a community-based long-term care facility. METHODS: A needs analysis was conducted to determine the organizational and individual level barriers to influenza vaccination of staff. Systems changes, educational interventions, and reminders were implemented based on the barriers assessment. Staff immunization rates were calculated over a 10-year period from 1996 to 2006. RESULTS: Organizational and individual barriers were identified and targeted. Using data from 1996 and 1997 as a baseline, staff immunization rates improved from 54% to 55% to between 74% and 95% over the past 4 years. CONCLUSIONS: Achieving and sustaining high staff influenza immunization rates is possible in a community-based long-term care facility with an involved quality improvement team and medical director.
