Prospective payment for nursing homes increased therapy provision without improving community discharge rates.

OBJECTIVES: To determine the impact of the prospective payment system (PPS) for skilled nursing facilities (SNFs) on therapy use and community discharge rates. DESIGN: Quasi-experimental study examining the predemonstration (1994) to demonstration (1997) change in amount of therapy provided, and in community discharge rates at PPS participating and nonparticipating facilities. SETTING: Eighteen PPS participating and 17 nonparticipating SNFs in five states. PARTICIPANTS: Two thousand sixty-seven admissions to 18 PPS participating and 17 nonparticipating SNFs in five states. MEASUREMENTS: We compared changes in number of physical and occupational therapy visits per stay for patients receiving therapy and likelihood of being located in the community 60 days after admission between 1994 and 1997. Analyses were stratified by functional category and risk adjusted using multivariate methods. RESULTS: Demographics and percentage of patients in each stratum were similar in participating and nonparticipating sites and between 1994 and 1997. Amount of therapy received by the highest-functioning patients increased in participating sites (19.3 to 26.5 visits per stay, P = .005), but not in nonparticipating sites (23.3 to 18.2, P = .98). After adjusting for covariates, likelihood of community discharge for the highest-functioning patients did not change between participating and nonparticipating sites. CONCLUSIONS: The highest-functioning patients treated under the SNF PPS demonstration experienced great increases in therapy, without any improvement in rate of community discharge.

Outcomes of older persons receiving rehabilitation for medical and surgical conditions compared with hip fracture and stroke.

OBJECTIVE: Older persons with general medical and surgical conditions increasingly receive posthospital rehabilitation care in nursing homes and rehabilitation hospitals. This study describes the characteristics of such patients, contrasted with patients with traditional rehabilitation diagnoses of hip fracture and stroke. DESIGN: Prospective cohort study. SETTING: Seventeen skilled nursing facilities and six rehabilitation hospitals in seven states. PARTICIPANTS: Medicare patients age 65 or older receiving posthospital rehabilitation. METHODS: A total of 290 medical/surgical patients were compared with 336 hip fracture and 429 stroke patients. Data were collected prospectively from charts, nursing assessments, and patient interviews. Patient characteristics associated with functional recovery and mortality were estimated using multivariate regression. RESULTS: Medical/surgical patients had greater premorbid activities of daily living (ADL) (P < .001) and instrumental activities of daily living (IADL) (P < .01) disability, but suffered less decline with the acute event than hip fracture or stroke patients (P < .001). Medical/surgical patients were more likely to recover premorbid ADL function (P < .05) but 1-year mortality was significantly greater (30% vs. 14% hip fracture; 18% stroke; P < .001). Predictors of functional recovery and mortality differed between the three groups. Among medical/surgical patients, premorbid ADL difficulty, cognitive impairment, a pressure ulcer at rehabilitation admission, and depression were associated with failure to recover premorbid function whereas increasing comorbidity and incontinence were associated with mortality. CONCLUSIONS: Medical/surgical patients represent a unique rehabilitation population. They experienced greater premorbid functional disability, less acute decline, but greater mortality than patients with traditional rehabilitation diagnoses. Further study of this distinct rehabilitation population may help identify patients most likely to benefit from rehabilitation.

Outcome and utilization differences for older persons with stroke in HMO and fee-for-service systems.

OBJECTIVES: To compare treatment and outcomes for older persons with stroke in Medicare health maintenance organizations (HMOs) and fee-for-service (FFS) systems. DESIGN: Inception cohort stratified by payer and followed for 1 year. SETTING: Six HMOs and five FFS systems with large Medicare populations in the West, Midwest, and Eastern United States. PARTICIPANTS: A total of 429 randomly selected stroke patients receiving rehabilitation in nursing homes or rehabilitation hospitals (RHs) from June 1993 to June 1995. MEASUREMENTS: Improvement in activities of daily living (ADLs) during rehabilitation, and ADL recovery, community residence, and utilization until 12 months after stroke. Outcomes were adjusted for premorbid function, marital status, comorbid illness, posthospital function, cognition, psychological problems, and stroke deficits. RESULTS: At baseline, HMO patients were more likely to be married, and less likely to be blind or have psychiatric diagnoses. HMO patients had shorter hospitalizations (P < .001), were less likely to be admitted to RHs (13% vs 85%, P < .001), and received fewer therapy and physician specialist visits (P < .001) but more home health visits (P < .001). During rehabilitation, FFS patients made greater improvement in ADLs (difference, 0.73 ADLs; 95% CI, .37-1.09). At 1 year, there was no difference in ADL recovery (difference, -0.24 ADL; 95% CI, -0.64-0.16), but FFS patients were more likely to reside in the community (adjusted OR, 1.8; 95% CI, 1.1-3.1), and HMO patients were more likely to reside in nursing homes (adjusted OR, 2.4; 95% CI, 1.1-5.5). CONCLUSION: Study findings suggest that short-term functional outcomes and eventual community residence rates are poorer for Medicare HMO patients with stroke than for stroke patients receiving FFS care, consistent with the lower intensity of rehabilitation (in nursing homes vs RHs) and less specialty physician care.

A comparison of functional outcomes after hip fracture in group/staff HMOs and fee-for-service systems.

CONTEXT: Previous studies examining differences in the quality of care between capitated and fee-for-service payment systems have focused on the care delivered in a single setting. No study to date has compared outcomes over an entire episode of care delivered across multiple settings. OBJECTIVE: To compare outcomes of care for patients receiving institutional rehabilitation for hip fracture in fee-for-service and group/staff HMO delivery systems. DESIGN: One-year prospective inception cohort. SETTING: Six hospital-based, integrated care systems paid on a traditional fee-for-service model and five group/staff HMOs (paid fixed capitation rate by Medicare). The 11 delivery systems were selected because of their commitment to geriatric rehabilitation. PATIENTS: 196 fee-for-service and 140 group/staff HMO patients with acute hip fracture were identified on admission to inpatient rehabilitation. MEASURES: Four primary outcomes--recovery of activities of daily living, improvement in ambulation, return to community living, and mortality--were measured at 3, 6, 9, and 12 months. Service utilization was assessed in the acute-care hospital setting, rehabilitation setting, and at each 3-month follow-up interval. Risk adjustment was performed by using multiple and logistic regression. RESULTS: Overall, no differences were found between patients in group/staff HMOs and fee-for-service patients. Group/staff HMO patients experienced improved functional recovery at 6 months (P < 0.01) and improved ambulation at 12 months (P = 0.05) compared with fee-for-service patients, although these were isolated findings. With regard to utilization, group/staff HMO delivery systems used physician services less intensively and substituted less-skilled allied health personnel. CONCLUSION: Compared with fee-for-service delivery systems, with a similar commitment to excellence in geriatric rehabilitation, group/staff HMOs can achieve equivalent outcomes in older patients recovering from hip fracture with less-intense service utilization.

Development and validation of a clinical prediction rule for prolonged nursing home residence after hip fracture.

OBJECTIVES: To develop and validate a clinical prediction rule for nursing home residence 6 months after a hip fracture. DESIGN: Two prospective cohort studies, a development study (DS) and a validation study (VS). SETTING: The DS included hip fracture patients admitted to 92 rehabilitation units or skilled nursing facilities; the VS included hip fracture patients from 11 integrated healthcare systems. PARTICIPANTS: A total of 344 community-dwelling hip fracture patients aged 65 and older participated in the DS; 239 similar patients were enrolled in the VS. INTERVENTION: None. MEASUREMENTS: The acute hospital record, nursing evaluations, and patient questionnaires provided information about demographics, physical and neuropsychological function, and comorbidity. Residence 6 months after fracture was determined by phone interview. Multivariate analysis identified predictors for a risk score to assess the likelihood of nursing home residence. RESULTS: 18.7% of patients in the DS resided in nursing homes 6 months after hip fracture. The four independent risk factors for institutionalization were (1) being unmarried (OR = 6.7 [95% CI 2.4 to 19]), (2) incontinence (OR = 2.3 [CI 1.2 to 4.7]), (3) dependence in ambulation (OR = 5.0 [CI 2.1 to 12.3]), and (4) cognitive impairment (OR = 6.6 [CI 3.3 to 13.2]). Of patients with all four risk factors, 73.2% were institutionalized at 6 months, compared with 0% of patients with no risk factors. In the VS, 6.1% of patients resided in nursing homes after 6 months, with a range from 50.0% of patients with four risk factors to 0% of those with no risk factors. Areas under receiver-operating characteristic curves for the prediction rule were 0.84 +/- .03 in the DS, and 0.81 +/- .06 in the VS. CONCLUSION: A clinical prediction rule using four easily measurable characteristics can identify individuals at high or low risk of nursing home residence 6 months after hip fracture.
