Impact of pressure ulcers on outcomes in inpatient rehabilitation facilities.

OBJECTIVE: The aim of this study was to examine the impact of pressure ulcers on inpatient rehabilitation facility (IRF) outcomes. DESIGN: This is a retrospective analysis of the IRF data in the United States from the Uniform Data System for Medical Rehabilitation between 2009 and 2011. The study sample included 2902 pairs of pressure ulcer and pressure ulcer-free patients upon IRF admission, matching on age at admission, sex, impairment groups, and comorbidity tier measures. The study outcomes were cognition and motor functional gains measured by the Functional Independence Measure instrument, IRF length of stay, and discharge to the community. RESULTS: The mean pressure ulcer prevalence upon IRF admission was 5.23%. After controlling for other covariates under study, the pressure ulcer group had a lower motor gain (20.12 vs. 21.58, P < 0.0001), had a longer length of stay (16.5 vs. 15.5, P < 0.0001), and were less likely to be discharged to the community after IRF stay (odds ratio, 0.72; 95% confidence interval, 0.62-0.84) than the patients without a pressure ulcer. CONCLUSIONS: The presence of a pressure ulcer among the patients seen in United States IRFs had no impact on cognition functional gain but was associated with a minor lower motor gain, a longer IRF length of stay, and lower odds of being discharged to the community.

Designing and implementing a system for tracking functional status after stroke: a feasibility study.

OBJECTIVE: To determine the feasibility of tracking stroke patients' functional outcomes in an integrated health system across a care continuum using the computer version of the Activity Measure of Post-Acute Care (AM-PAC). SETTING: A large integrated health care system in northern California. PARTICIPANTS: A total of 222 stroke patients (aged ≥18 years) who were hospitalized after an acute cerebrovascular accident. METHODS: An AM-PAC assessment was made at discharge from sites of care, including acute hospital, inpatient rehabilitation hospital, skilled nursing facility, home during home care, and outpatient settings. Assessments also were completed in the patient's home at 6 months. Data from the AM-PAC program were integrated with the health care system's databases. MAIN OUTCOME MEASUREMENTS: (1) AM-PAC administration time at the various sites of care; (2) assessment of a floor or a ceiling effect; and (3) administrative burden of tracking participants. RESULTS: AM-PAC assessment sessions averaged 7.9 minutes for data acquisition in 3 domains: Basic Mobility, Activities of Daily Living, and Applied Cognition. Participants answered, on average, 27 AM-PAC questions per session. A small ceiling effect was observed at 6 months, and there was a larger ceiling effect when the instrument was administered in an institution, ie, when the AM-PAC institutional item bank was used rather than the community item bank. It was feasible to track patients and to assess their function using the AM-PAC instrument from institutional to community settings. Implementation of the AM-PAC in clinical environments, and the success of the project, were influenced by instrumental, technological, operational, resource, and cultural factors. CONCLUSIONS: This study demonstrates the feasibility of implementing a single functional outcome instrument in clinical and community settings to measure rehabilitation functional outcomes of stroke patients. Integrating the AM-PAC measurement system into clinical workflows and the electronic medical record could provide assistance to clinicians for medical decision making, functional prognostication, and discharge planning.

Does postacute care site matter? A longitudinal study assessing functional recovery after a stroke.

OBJECTIVE: To determine the impact of postacute care site on stroke outcomes. DESIGN: Prospective cohort study. SETTING: Four northern California hospitals that are part of a single health maintenance organization. PARTICIPANTS: Patients with stroke (N=222) enrolled between February 2008 and July 2010. INTERVENTION: Not applicable. MAIN OUTCOME MEASURE: Baseline and 6-month assessments were performed using the Activity Measure for Post Acute Care (AM-PAC), a test of self-reported function in 3 domains: Basic Mobility, Daily Activities, and Applied Cognition. RESULTS: Of the 222 patients analyzed, 36% went home with no treatment, 22% received home health/outpatient care, 30% included an inpatient rehabilitation facility (IRF) in their care trajectory, and 13% included a skilled nursing facility (but not IRF) in their care trajectory. At 6 months, after controlling for important variables such as age, functional status at acute care discharge, and total hours of rehabilitation, patients who went to an IRF had functional scores that were at least 8 points higher (twice the minimally detectable change for the AM-PAC) than those who went to a skilled nursing facility in all 3 domains and in 2 of 3 functional domains compared with those who received home health/outpatient care. CONCLUSIONS: Patients with stroke may make more functional gains if their postacute care includes an IRF. This finding may have important implications as postacute care delivery is reshaped through health care reform.

Evaluation of patient and proxy responses on the activity measure for postacute care.

BACKGROUND AND PURPOSE: Our objective was to examine the agreement between adult patients with stroke and family member or clinician proxies in activity measure for postacute care (AM-PAC) summary scores for daily activity, basic mobility, and applied cognitive function. METHODS: This study involved 67 patients with stroke admitted to a hospital within the Kaiser Permanente of Northern California system and were participants in a parent study on stroke outcomes. Each participant and proxy respondent completed the AM-PAC by personal or telephone interview at the point of hospital discharge or during ≥1 transitions to different postacute care settings. RESULTS: The results suggest that for patients with a stroke proxy, AM-PAC data are robust for family or clinician proxy assessment of basic mobility function and clinician proxy assessment of daily activity function, but less robust for family proxy assessment of daily activity function and for all proxy groups' assessments of applied cognitive function. The pattern of disagreement between patient and proxy was, on average, relatively small and random. There was little evidence of systematic bias between proxy and patient reports of their functional status. The degree of concordance between patient and proxy was similar for those with moderate to severe strokes compared with mild strokes. CONCLUSIONS: Patient and proxy ratings on the AM-PAC achieved adequate agreement for use in stroke research when using proxy respondents could reduce sample selection bias. The AM-PAC data can be implemented across institutional as well as community care settings while achieving precision and reducing respondent burden.

The California Kaiser Permanente Health System: evolving to meet the needs of people with disabilities.

This review documents the history of one large health system's approach to the enactment of the Americans with Disabilities Act, following the settlement of a lawsuit. This paper represents the various activities within the Kaiser Permanente health system from 2001 to the present that were conducted to improve access and remove architectural, attitudinal, and other barriers for people with disabilities, to educate and train providers concerning culturally competent care for people with disabilities, and to develop patient-centered best practices and models of care for people with disabilities. Health systems can improve care for people with disabilities through organized, multifaceted, and ongoing approaches to removal of barriers, provider education and training in culturally competent care, and establishment of patient-centered best practices and models of care.

Memory enhancement in healthy older adults using a brain plasticity-based training program: a randomized, controlled study.

Normal aging is associated with progressive functional losses in perception, cognition, and memory. Although the root causes of age-related cognitive decline are incompletely understood, psychophysical and neuropsychological evidence suggests that a significant contribution stems from poorer signal-to-noise conditions and down-regulated neuromodulatory system function in older brains. Because the brain retains a lifelong capacity for plasticity and adaptive reorganization, dimensions of negative reorganization should be at least partially reversible through the use of an appropriately designed training program. We report here results from such a training program targeting age-related cognitive decline. Data from a randomized, controlled trial using standardized measures of neuropsychological function as outcomes are presented. Significant improvements in assessments directly related to the training tasks and significant generalization of improvements to nonrelated standardized neuropsychological measures of memory (effect size of 0.25) were documented in the group using the training program. Memory enhancement appeared to be sustained after a 3-month no-contact follow-up period. Matched active control and no-contact control groups showed no significant change in memory function after training or at the 3-month follow-up. This study demonstrates that intensive, plasticity-engaging training can result in an enhancement of cognitive function in normal mature adults.
