Objective: To compare functional outcomes at discharge across postacute settings. Design: Prospective observational cohort study. Setting: Eleven inpatient rehabilitation facilities (IRFs), 8 freestanding skilled nursing facilities (SNFs), and 1 hospitalbased SNF from across the United States. Participants: Consecutively enrolled patients (Nϭ2152): patients with knee replacement (nϭ1401) and patients with hip replacement (nϭ751). Interventions: None; examination of existing practice patterns. Main Outcome Measure: FIM discharge motor score. Results: Freestanding SNF patients entered with higher motor FIM scores and left with higher scores than did IRF patients. IRF patients, however, achieved larger motor FIM gains and achieved them in a shorter time. In multivariate models controlling for patient differences and onset days, IRFs were associated with better discharge motor outcomes, but the overall setting effect was not large. The largest motor FIM differences were between medium-volume IRFs and low-volume freestanding SNFs: 4.6 motor FIM points for patients with knee replacement and 7.3 motor FIM points for patients with hip replacement. Other differences between settings were much smaller. Multivariate models explained between a third and a half of the variance in outcome. Conclusions: As a group, IRFs had better motor FIM outcomes than did SNFs, but the size of the IRF advantage was not large. Other important facility and practice characteristics also were associated with discharge outcomes after joint replacement rehabilitation. Earlier and more intensive rehabilitation was associated with better outcomes. The volume of joint replacement patients seen by a facility also plays a part: medium-volume facilities among both SNFs and IRFs had better outcomes.

Objective: To examine functional and health status outcomes of patients with joint replacement discharged from a skilled nursing facility (SNF) or an inpatient rehabilitation facility (IRF). Design: Postdischarge follow-up interview study at 7.5 months after admission. Setting: Five freestanding SNFs, 1 hospital-based SNF, and 6 IRFs. Participants: Patients (Nϭ856): 561 with knee replacement and 295 with hip replacement. Interventions: None. Main Outcome Measures: FIM and Short-Form 12-Item Health Survey (SF-12). Results: Among patients with knee and hip replacement, IRF patients made larger motor FIM gains from admission and discharge to follow-up. IRF patients, however, were admitted with lower FIM scores and also had more to gain (especially given the ceiling effects within the FIM at follow-up). When adjusted for case mix, IRF patients made larger motor FIM gains and had higher SF-12-related scores among patients with hip replacement but not among patients with knee replacement. Multivariate regressions found modest setting effects that favored IRFs, and the setting effects explained only a modest portion of the variance in motor FIM outcomes. Conclusions: At follow-up, patients with joint replacement discharged from IRFs had better motor FIM outcomes than those discharged from freestanding SNFs and the hospitalbased SNF. Settings did not differ materially in terms of SF-12 outcomes. Findings do not favor one setting decisively over another. A sole focus on initial postacute placement overlooks the larger trajectory of postacute care that needs to be managed to achieve superior outcomes.
OBJECTIVE: To examine differences in outcomes of patients after lower-extremity joint replacement across 3 post-acute care (PAC) rehabilitation settings. DESIGN: Prospective observational cohort study. SETTING: Skilled nursing facilities (SNFs; n=5), inpatient rehabilitation facilities (IRFs; n=4), and home health agencies (HHAs; n=6) from 11 states. PARTICIPANTS: Patients with total knee (n=146) or total hip replacement (n=84) not related to traumatic injury. INTERVENTIONS: None. MAIN OUTCOME MEASURE: Self-care and mobility status at PAC discharge measured by using the Inpatient Rehabilitation Facility Patient Assessment Instrument. RESULTS: Based on our study sample, HHA patients were significantly less dependent than SNF and IRF patients at admission and discharge in self-care and mobility. IRF and SNF patients had similar mobility levels at admission and discharge and similar self-care at admission, but SNF patients were more independent in self-care at discharge. After controlling for differences in patient severity and length of stay in multivariate analyses, HHA setting was not a significant predictor of self-care discharge status, suggesting that HHA patients were less medically complex than SNF and IRF patients. IRF patients were more dependent in discharge self-care even after controlling for severity. For the full discharge mobility regression model, urinary incontinence was the only significant covariate. CONCLUSIONS: For the patients in our U.S.-based study, direct discharge to home with home care was the optimal strategy for patients after total joint replacement surgery who were healthy and had social support. For sicker patients, availability of 24-hour medical and nursing care may be needed, but intensive therapy services did not seem to provide additional improvement in functional recovery in these patients.

QUESTIONS UNDER STUDY / PRINCIPLES: The aims of this study were to identify the determinants influencing the inpatient rehabilitation length of stay (LoS) and discharge modality (DisMod) after hip or knee replacement surgery. METHODS: Data were retrieved for 306 patients (185 females, 121 males) who were admitted to a Swiss orthopaedic rehabilitation facility between 2007 and 2008 after hip or knee replacement surgery. LoS and DisMod were extracted from the medical files along with an additional seven binary and six continuous variables (including scores of timed-get-up-and-go [TUG], walking distance [WDT] and stair climbing tests [FIM_St]). Nonparametric procedures were used to detect differences between the gender groups. For the analysis of the LoS determinants, a linear regression model was used. The nonmotor performance test determinants of DisMod were analysed using a logistic regression model, whereas the motor performance test determinants were examined using binary classification. For both regression models, a backward procedure was used. RESULTS: Unlike DisMod, LoS calculations were conducted after stratification for gender. The simplified regression models explained 22% (females) and 31% (males) of the LoS variance and 20% (both genders) of the DisMod variance. TUG, WDT and FIM_St were all important predictors for LoS, whereas DisMod could be best predicted by WDT. CONCLUSIONS: Patients with good motor ability at admission were discharged earlier and more frequently to home. These findings might be of importance for preoperative physiotherapeutic care and might help to improve care planning as well as more accurately predict the access to inpatients beds and the allocation of resources.
Justifying Rehabilitation Intensity Through Functional Performance Measures in Postacute Care
The American journal of occupational therapy : official publication of the American Occupational Therapy Association
The Centers for Medicare and Medicaid Services (CMS) has scrutinized the provision of rehabilitation services in skilled nursing facilities (SNFs) for some time. Little research guidance exists on appropriate dosage or rehabilitation intensity (RI) among SNF patients or patients in other postacute care (PAC) settings. CMS developed a PAC assessment, the Continuity Assessment Record and Evaluation (CARE) Tool, in response to questions about what issues drive placement in various PAC settings under Medicare. The ability to adequately assess functional outcomes and correlate them to the RI provided by using the CARE Tool is promising. However, further research, policy advocacy, and practice analysis must be undertaken to promote and protect adequate access to occupational therapy and physical therapy in SNFs and other PAC settings. Individual practitioners must participate in data gathering to ensure that the data for analysis are fully informed by the occupational therapy perspective.
Disparities in post-acute rehabilitation care for joint replacement
Arthritis Care and Research, 2011
Objectives-To determine the extent to which demographic and geographic disparities exist in the use of post-acute rehabilitation care (PARC) for joint replacement. Methods-Cross-sectional analysis of two years (2005-2006) of population-based hospital discharge data from 392 hospitals in four states (AZ, FL, NJ, WI). 164,875 individuals 45 years and older admitted to the hospital for a hip or knee joint replacement and who survived their inpatient stay were identified. Three dichotomous dependent variables were examined: 1) discharge to home vs. institution (i.e., skilled nursing facility (SNF) or inpatient rehabilitation facility (IRF)); 2) discharge to home with vs. without home health (HH); and 3) discharge to a SNF vs. IRF. Multilevel logistic regression analyses were conducted to identify demographic and geographic disparities in PARC use, controlling for illness severity/comorbidities, hospital characteristics, and PARC supply. Interactions among race, socioeconomic, and geographic variables were explored. Results-Considering PARC as a continuum from more to less intensive care in regard to hours of rehabilitation/day (e.g., IRF→SNF→HH→no HH), the uninsured received less intensive care in all three models. Individuals on Medicaid and those of lower SES received less intensive care in the HH/no HH and SNF/IRF models. Individuals living in rural areas received less intensive care in the institution/home and HH/no HH models. The effect of race was modified by insurance and by state. In most instances minorities received less intensive care. PARC use varied by hospital. Conclusions-Efforts to further understand the reasons behind these disparities and their effect on outcomes are needed.
