Trends in length of stay, living setting, functional outcome, and mortality following medical rehabilitation.

CONTEXT: Changes in reimbursement have reduced length of stay (LOS) for patients receiving inpatient medical rehabilitation. The impact of decreased LOS on functional status, living setting, and mortality is not known. OBJECTIVE: To examine changes in LOS, functional status, living setting, and mortality in patients completing inpatient rehabilitation. DESIGN: Retrospective cohort study from 1994 through 2001 using information submitted to the Uniform Data System for Medical Rehabilitation. SETTING AND PARTICIPANTS: Data were analyzed from 744 inpatient medical rehabilitation hospitals and centers located in 48 US states. A total of 148,807 patient records from 5 impairment groups (stroke, brain dysfunction, spinal cord dysfunction, other neurologic conditions, and orthopedic conditions) were examined. Patients' mean age was 67.8 (SD, 15.8) years; the sample was 59% female and 81% non-Hispanic white. MAIN OUTCOME MEASURES: Discharge setting, follow-up living setting, change in functional status, and mortality. RESULTS: Median LOS decreased from 20 to 12 days (P<.001) from 1994 to 2001. The proportional decrease in median LOS was greatest (42%) for patients with orthopedic conditions. Mean days to follow-up remained constant from 89 in 1994 to 90 in 2001. Functional status was clinically stable, while efficiency (functional status change divided by LOS) increased significantly (P<.001). Rates of discharge to home and living at home at follow-up remained stable, ranging from 81% to 93%. However, mortality at 80- to 180-day follow-up increased from less than 1% in 1994 to 4.7% in 2001. CONCLUSIONS: Length of stay for inpatient rehabilitation decreased substantially from 1994 to 2001. Effectiveness as measured by change in functional status did not change clinically, and living setting did not change. Efficiency for functional outcomes improved but mortality at follow-up increased.

Satisfaction with medical rehabilitation after spinal cord injury.

STUDY DESIGN: Retrospective. OBJECTIVE: To predict satisfaction with medical rehabilitation. SUMMARY OF BACKGROUND DATA: While spinal cord injury (SCI) patient satisfaction with life and community services has been investigated, satisfaction with medical rehabilitation has not. METHODS: Information submitted to the Uniform Data System for Medical Rehabilitation (1998-2001) by 134 hospitals/rehabilitation facilities in the United States (n = 6,205 patients with SCI) was examined. Predictors were sociodemographic variables, Case Mix Groupings (CMG) (401-505, 5001), length of stay, rehospitalization, follow-up therapy, and health maintenance. Satisfaction was assessed at a mean of 92.2 days (SD 11.9 days) postdischarge. Data were analyzed according to who reported the outcome (patient, n = 3,858 or family/other, n = 1,869). Statistical modeling was conducted using logistic regression. RESULTS: High overall satisfaction was reported (94%). Significant predictors for the patient report data were CMG and rehospitalization. Compared with CMG 5001 (short stay, <3 days), patients in CMGs 401/2/3 and 501/2/3/4/5 had a 54% to 74% lower likelihood of being dissatisfied. Rehospitalized patients had a higher likelihood of dissatisfaction (odds ratio 2.3, 95% confidence interval 1.7 to 3.2). Significant predictors for the family/other report data were CMG (compared to CMG 5001, CMGs 401/2, 403, and 501/2 had a 70% lower likelihood of dissatisfaction), rehospitalization (odds ratio 1.7, 95% confidence interval 1.1-2.5), and marital status (married = 50% lower likelihood of dissatisfaction, 95% confidence interval 0.26-0.96). CONCLUSIONS: Satisfaction with medical rehabilitation services following SCI is related to functional abilities, rehospitalization, and marital status. Slightly different results were found for whether satisfaction was rated by the patient or family/other. The complex relationships among satisfaction, patient demographics, and functional status require continued examination.

The development of the School Function Assessment Chinese version for cross-cultural use in Taiwan.

The primary purpose of this research project was to translate and adapt the School Function Assessment (SFA), a standardized criterion-referenced instrument that measures school-related functional skills, for its cross-cultural use in Taiwan. The project consisted of four study phases: translation, cultural adaptation, pilot testing, and field testing for standardization. A series of rigorous procedures including the method of translation and back-translation, team consensus for cultural adaptation, and Rasch modelling techniques were used to address various dimensions of cross-cultural equivalence and psychometric properties of the translated SFA. The protocols that were developed as well as technical issues that were addressed in this project provide useful guidelines for international occupational therapists who are interested in translating and adapting instruments for cross-cultural use.

Comparison of logistic regression and neural network analysis applied to predicting living setting after hip fracture.

PURPOSE: Describe and compare the characteristics of artificial neural networks and logistic regression to develop prediction models in epidemiological research. METHODS: The sample included 3708 persons with hip fracture from 46 different states included in the Uniform Data System for Medical Rehabilitation. Mean age was 75.5 years (sd=14.2), 73.7% of patients were female, and 82% were non-Hispanic white. Average length of stay was 17.0 days (sd=10.6). The primary outcome measure was living setting (at home vs. not at home) at 80 to 180 days after discharge. RESULTS: Statistically significant variables (p <.05) in the logistic model included follow-up therapy, sphincter control, self-care ability, marital status, age, and length of stay. Areas under the receiver operating characteristic curves were 0.67 for logistic regression and 0.73 for neural network analysis. Calibration curves indicated a slightly better fit for the neural network model. CONCLUSIONS: Follow-up therapy and independent bowel and/or bladder function were strong predictors of living at home up to 6 months after hospitalization for hip fracture. No practical differences were found between the predictive ability of logistic regression and neural network analysis in this sample.

Mapping the neural systems that mediate the Paced Auditory Serial Addition Task (PASAT).

The paced auditory serial addition task (PASAT), in which subjects hear a number-string and add the two most-recently heard numbers, is a neuropsychological test sensitive to cerebral dysfunction. We mapped the brain regions activated by the PASAT using positron emission tomography (PET) and 15O-water to measure cerebral blood flow. We parsed the PASAT by mapping sites activated by immediate repetition of numbers and by repetition of the prior number after the presentation of the next number in the series. The PASAT activated dispersed non-contiguous foci in the superior temporal gyri, bifrontal and biparietal sites, the anterior cingulate and bilateral cerebellar sites. These sites are consistent with the elements of the task that include auditory perception and processing, speech production, working memory, and attention. Sites mediating addition were not identified. The extent of the sites activated during the performance of the PASAT accounts for the sensitivity of this test and justifies its use in a variety of seemingly disparate conditions.

Satisfaction with medical rehabilitation in patients with orthopedic impairment.

OBJECTIVE: To examine patient satisfaction after orthopedic impairment at 80 to 180 days after inpatient rehabilitation. DESIGN: Retrospective design examining records from facilities subscribing to the Uniform Data System for Medical Rehabilitation (UDSmr). SETTING: Information submitted to UDSmr from 1997 to 1998 by 177 hospital and rehabilitation facilities from 40 states. PARTICIPANTS: The sample (N=7781) was 72.63% female and 88.60% non-Hispanic white, with a mean age +/- standard deviation of 73.07+/-11.81 years, and average length of stay (LOS) of 13.84+/-10.48 days. INTERVENTION: Usual rehabilitation care. Main outcome measures Level of satisfaction 80 to 180 days after discharge as well as motor, cognitive, and subscale ratings for the FIM trade mark instrument. Predictor variables included gender, age, English language, marital status, discharge setting, LOS, rehospitalization, FIM gain, and primary payer. RESULTS: A logistic regression model was used to predict patient satisfaction at follow-up. Five statistically significant (P<.05) variables were found and correctly classified 94.9% of the patients. Discharge motor FIM rating, rehospitalization, age, patient's primary language, and discharge setting were associated with increased satisfaction. Discharge motor FIM ratings were significantly associated with increased satisfaction in patients with joint replacements and lower-extremity fractures. CONCLUSION: unctional and demographic variables were identified as predictors of satisfaction in patients with orthopedic impairments.

Disparity in health services and outcomes for persons with hip fracture and lower extremity joint replacement.

OBJECTIVE: Examine disparity in health services and outcomes for adults with a hip fracture or lower extremity joint replacement. MATERIALS AND METHODS: This study examined 28,522 patient records including 12,328 (mean age 76.6 years) with hip fracture and 16,194 (mean age 71.8 years) with joint replacement. RESULTS: Non-Hispanic white and black patients were significantly (P < 0.05) more likely to be discharged home alone and responsible for their own care than were Asian or Hispanic patients. Sixty-four percent of Hispanic patients received inpatient rehabilitation after hip fracture and 36% after hip or knee arthroplasty. In contrast, 58% of non-Hispanic white persons, 67% of black persons, and 56% of Asian persons received inpatient medical rehabilitation after hip or knee joint replacement. CONCLUSION: Disparity in outcomes appeared to be related to family structure and social support.

Effect of functional gain on satisfaction with medical rehabilitation after stroke.

OBJECTIVE: To examine the association between gain in motor and cognitive functional status with patient satisfaction 3-6 mo after rehabilitation discharge. DESIGN: Patient satisfaction and changes in functional status were examined in 18,375 patients with stroke who received inpatient medical rehabilitation. Information was obtained from 144 hospitals and rehabilitation facilities contributing records to the Uniform Data System for Medical Rehabilitation and the National Follow-up Services. RESULTS: Data analysis revealed significant (P < 0.05) differences in satisfaction responses based on whether information was collected from patient self-report or from a family member proxy, and the two subsets were analyzed separately. Logistic regression revealed the following significant predictors of satisfaction for data collected from stroke patients: cognitive and motor gain, rehospitalization, who the patient was living with at follow-up, age, and follow-up therapy. In the patient-reported data subset, compared with patients who showed improved cognitive or motor functional status, those with no change, respectively, had a 31% and 33% reduced risk of dissatisfaction. In addition, rehospitalized patients had a higher risk of dissatisfaction. For the proxy reported data subset, significant influences on satisfaction were health maintenance, rehospitalization, stroke type, ethnicity, cognitive FIM gain, length of stay, and follow-up therapy. CONCLUSIONS: Ratings of satisfaction with rehabilitation services were affected by change in functional status and whether the information was collected from patient rating or proxy response.

Functional gains and therapy intensity during subacute rehabilitation: a study of 20 facilities.

OBJECTIVES: To document patient, program characteristics, and therapy service provision in subacute rehabilitation across 3 types of facilities that provide subacute rehabilitation, to examine the determinants of therapy intensity, and to evaluate the contribution of rehabilitation services to functional gains. DESIGN: A retrospective study linking administrative billing data and patients' functional assessment records. SETTING: Twenty facilities part of the Uniform Data System for Medical Rehabilitation (UDSMR) subacute database PARTICIPANTS: A total of 1976 billing records of patients with stroke, orthopedic, and debility impairments, discharged in 1996 and 1997, were retrieved and linked with the FIM trade mark instrument ratings from UDSMR subacute database. INTERVENTIONS: Not applicable. MAIN OUTCOMES MEASURES: Total therapy intensity and Rasch-transformed FIM domain gains (ie, gains in self-care, mobility, cognition). RESULTS: Therapy intensity was mostly determined by impairment and facility type, although variances explained by the predictors were small. Patients in all 3 impairment groups made functional gains; gains were related weakly, although significantly, to therapy intensity and rehabilitation duration after controlling for other variables. CONCLUSIONS: The provision of rehabilitation therapies varied across facilities. Skilled nursing facilities with subacute rehabilitation units tended to provide more therapies than subacute units in acute or rehabilitation hospitals.
