Mean flow velocity in the middle cerebral artery is associated with rehabilitation success in ischemic stroke patients

Treger I, Aidinof L, Lutsky L, Kalichman L. Mean flow velocity in the middle cerebral artery is associated with rehabilitation success in ischemic stroke patients.

Objective

To evaluate the association between mean flow velocity (MFV) in the middle cerebral artery (MCA) measured by using transcranial Doppler (TCD) and functional and neurologic impairment change during rehabilitation after acute stroke.

Design

Cross-sectional observational study.

Setting

Acute neurologic rehabilitation department.

Participants

Consecutive patients (N=67; 53 men, 14 women; mean ± SD age, 61.54±8.92y) referred to the rehabilitation center during the first 6 months of 2006 for a first ischemic stroke in the MCA area.

Interventions

Not applicable.

Main Outcome Measures

All subjects were evaluated on admission and at discharge by using the National Institutes of Health Stroke Scale (NIHSS) and the FIM. TCD measurements of MFV of the ipsilateral and contralateral MCA were performed on admission (during the first 20 days after stroke) and a few days before discharge.

Results

Contralateral MFV at admission was associated significantly with all indexes of functional rehabilitation success (FIM score at discharge [β=.169; P=.010], change in FIM score [β=.554; P=.010], relative improvement in FIM score [β=.783; P=.003]). No significant association was found between indexes of NIHSS change and ipsilateral or contralateral MFV.

Conclusions

Ipsilateral or contralateral MFV measured at admission did not change during the 2-month rehabilitation period. Our data showed a significant association between blood flow velocity in the contralateral MCA and functional rehabilitation parameters of patients after first ischemic stroke in the MCA area.     

Factors Predicting Inpatient Rehabilitation Length of Stay of Acute Stroke Patients in Singapore

Tan WS, Heng BH, Chua KS, Chan KF. Factors predicting inpatient rehabilitation length of stay of acute stroke patients in Singapore.

Objective

To determine the predictors of hospital length of stay (LOS) of stroke patients at the point of admission.

Design

A retrospective cohort study.

Setting

An acute hospital rehabilitation center in Singapore.

Participants

Stroke patients (N=491) admitted between March 2005 and December 2006.

Interventions

None.

Main Outcome Measures

Rehabilitation LOS was calculated as the total number of rehabilitation days before discharge. We measured the functional status of patients by using the Functional Independence Measure (FIM).

Results

The median LOS was 29 days (mean = 30.8d). Independent clinical and sociodemographic characteristics found to significantly predict rehabilitation LOS were FIM motor score at admission, the presence of more than 3 comorbid conditions at admission, living with nonimmediate relatives before admission, and the hospital subsidy status of the patient. In particular, the admission FIM motor score explained 43% of the variation in LOS and decreased the LOS by approximately 1.1 days for each 1-point increase in score.

Conclusion

Patients' socioeconomic status and family structure was found to influence LOS and should be considered in allocating resources and determining treatment need. The extent of motor function of patients at admission is an important factor influencing rehabilitation LOS and is a useful tool for facilitating rehabilitation resource planning for stroke patients.     

Utility of Functional Status for Classifying Community Versus Institutional Discharges After Inpatient Rehabilitation for Stroke

Reistetter TA, Graham JE, Deutsch A, Granger CV, Markello S, Ottenbacher KJ. Utility of functional status for classifying community versus institutional discharges after inpatient rehabilitation for stroke.

Objective

To evaluate the ability of patient functional status to differentiate between community and institutional discharges after rehabilitation for stroke.

Design

Retrospective cross-sectional design.

Setting

Inpatient rehabilitation facilities contributing to the Uniform Data System for Medical Rehabilitation.

Participants

Patients (N=157,066) receiving inpatient rehabilitation for stroke from 2006 and 2007.

Interventions

Not applicable.

Main Outcome Measure

Discharge FIM rating and discharge setting (community vs institutional).

Results

Approximately 71% of the sample was discharged to the community. Receiver operating characteristic curve analyses revealed that FIM total performed as well as or better than FIM motor and FIM cognition subscales in differentiating discharge settings. Area under the curve for FIM total was .85, indicating very good ability to identify persons discharged to the community. A FIM total rating of 78 was identified as the optimal cut point for distinguishing between positive (community) and negative (institution) tests. This cut point yielded balanced sensitivity and specificity (both=.77).

Conclusions

Discharge planning is complex, involving many factors. Identifying a functional threshold for classifying discharge settings can provide important information to assist in this process. Additional research is needed to determine if the risks and benefits of classification errors justify shifting the cut point to weight either sensitivity or specificity of FIM ratings.     

Rehabilitation Outcomes of Stroke Patients With and Without Diabetes

Objective

To investigate the relation of diabetes comorbidity and the rehabilitation outcomes of patients with stroke.

Design

Secondary data analysis.

Setting

Inpatient rehabilitation facilities.

Participants

Patients with stroke (N=35,243) who received inpatient rehabilitation in 2004 through 2008.

Interventions

None.

Main Outcome Measures

FIM, length of stay, and discharge destination.

Results

Mean age ± SD of the sample was 71.0±13.2 years. The percent of the sample of Medicare beneficiaries was 53.8%, whereas 46.2% had other sources of funding. Of the patients in the sample, 34.5% had a comorbidity of diabetes, with 17.2% classified as tier-eligible and 82.8% as nontier eligible. Findings included that patients in this sample with diabetes were admitted for rehabilitation services at a younger age than those without diabetes and support previous studies in which tier-eligible diabetes comorbidities moderated by patient age were found to be significant predictors of stroke rehabilitation outcomes. Furthermore, similar findings remained regardless of payer source.

Conclusions

This study provides additional evidence that diabetes as a comorbidity is significantly related to stroke rehabilitation outcome, but the relation is moderated by patient age.     

Rates and Predictors of Manual and Powered Wheelchair Use for Persons With Stroke: A Retrospective Study in a Canadian Rehabilitation Center

Mountain AD, Kirby RL, MacLeod DA, Thompson K. Rates and predictors of manual and powered wheelchair use for persons with stroke: a retrospective study in a Canadian rehabilitation center.

Objectives

To determine the rates of manual and powered wheelchair use at discharge for people with stroke admitted to a rehabilitation center and to determine whether any predictors of wheelchair use at discharge could be identified.

Design

Retrospective cohort study.

Setting

Rehabilitation center.

Participants

Consecutive former inpatients (N=100) with a primary diagnosis of stroke, a sample of convenience.

Interventions

None.

Main Outcome Measures

We reviewed the inpatient health records to determine the rates of wheelchair use at discharge and to record some readily available demographic and clinical data that might serve as predictors of wheelchair use.

Results

At discharge, 40 people (40%) were using manual wheelchairs, 1 person (1%) was using a powered wheelchair, and 59 (59%) were not using a wheelchair. Of the patients who were walkers on admission (ie, walking FIM scores of 6 or 7), none (0%) used wheelchairs at discharge. Of those with nonwalking FIM scores (1-5) on admission, 56% were using wheelchairs at discharge. Multivariate analyses revealed that the adjusted odds ratios of using a wheelchair (manual or powered) were 3.33 (95% confidence interval [CI], 1.33-8.33) for those with left-hemisphere versus right-hemisphere strokes (P=.010), .94 (CI, .91-.96) for each point rise in the total raw FIM score on admission (P<.0001), and 19.46 (CI, 6.33-59.81) if the total admission FIM score was less than 80 versus greater than or equal to 80 (P<.0001).

Conclusions

On discharge from our rehabilitation center, 40% of people with stroke were using manual wheelchairs and 1% powered wheelchairs. People who were not walking on admission, those with left-hemisphere strokes, and those with lower total admission FIM scores were more likely to use a wheelchair. These findings may permit clinicians to predict wheelchair use better early in the rehabilitation process, when it can affect rehabilitation planning.     

Paraplegia after aortic aneurysm repair versus traumatic spinal cord injury: functional outcome, complications, and therapy intensity of inpatient rehabilitation

Yokoyama O, Sakuma F, Itoh R, Sashika H. Paraplegia after aortic aneurysm repair versus traumatic spinal cord injury: functional outcome, complications, and therapy intensity of inpatient rehabilitation.

Objective

To compare outcomes, complications, and therapy intensity of inpatient rehabilitation in patients with paraplegia caused by spinal cord injury associated with aortic aneurysm repair (SCI-AA) versus patients with traumatic spinal cord injury (SCI).

Design

Case-controlled study.

Setting

SCI unit in a rehabilitation center.

Participants

Seventeen patients with SCI-AA and 17 patients with traumatic SCI.

Intervention

Standard rehabilitation therapy for SCI.

Main Outcome Measures

Length of stay (LOS) in acute and rehabilitation hospitals; FIM instrument scores; FIM change; FIM efficiency; complications; therapy intensity; and ambulatory state and return to community at discharge.

Results

No significant differences were noted in acute and rehabilitation LOS and admission FIM scores. Discharge FIM scores, FIM change, and FIM efficiencies were significantly lower in the SCI-AA group, which had many complications related to AA and SCI. Intensity of rehabilitation sports therapy in the SCI-AA group was significantly lower than that of the traumatic SCI group, but total therapy intensity did not differ significantly. Both had similar rates of return to ambulatory state and discharge to the community.

Conclusions

SCI-AA patients had many complications that interfered with rehabilitation therapy, and could not achieve functional gains comparable to those with traumatic SCI. However, both groups achieved comparable success with return to ambulatory state and discharge to the community.     

Black-white differences in patient characteristics, treatments, and outcomes in inpatient stroke rehabilitation

Horn SD, Deutscher D, Smout RJ, DeJong G, Putman K. Black-white differences in patient characteristics, treatments, and outcomes in inpatient stroke rehabilitation.

Objective

To describe racial differences in patient characteristics, nontherapy ancillaries, physical therapy (PT), occupational therapy (OT), and functional outcomes at discharge in stroke rehabilitation.

Design

Multicenter prospective observational cohort study of poststroke rehabilitation.

Setting

Six U.S. inpatient rehabilitation facilities.

Participants

Black and white patients (n=732), subdivided in case-mix subgroups (CMGs): CMGs 104 to 107 for moderate strokes (n=397), and CMGs 108 to 114 for severe strokes (n= 335).

Interventions

Not applicable.

Main Outcome Measure

FIM.

Results

Significant black-white differences in multiple patient characteristics and intensity of rehabilitation care were identified. White subjects took longer from stroke onset to rehabilitation admission and were more ambulatory prior to stroke. Black subjects had more diabetes. For patients with moderate stroke, black subjects were younger, were more likely to be women, and had more hypertension and obesity with body mass index greater than or equal to 30. For patients with severe stroke, black subjects were less sick and had higher admission FIM scores. White subjects received more minutes a day of OT, although black subjects had significantly longer median PT and OT session duration. No black-white differences in unadjusted stroke rehabilitation outcomes were found.

Conclusions

Reasons for differences in rehabilitation care between black and white subjects should be investigated to understand clinicians' choice of treatments by race. However, we did not find black-white differences in unadjusted stroke rehabilitation outcomes.     

Team training and stroke rehabilitation outcomes: a cluster randomized trial

Strasser DC, Falconer JA, Stevens AB, Uomoto JM, Herrin J, Bowen SE, Burridge AB. Team training and stroke rehabilitation outcomes: a cluster randomized trial.

Objective

To test whether a team training intervention in stroke rehabilitation is associated with improved patient outcomes.

Design

A cluster randomized trial of 31 rehabilitation units comparing stroke outcomes between intervention and control groups.

Setting

Thirty-one Veterans Affairs medical centers.

Participants

A total of 237 clinical staff on 16 control teams and 227 staff on 15 intervention teams. Stroke patients (N=487) treated by these teams before and after the intervention.

Intervention

The intervention consisted of a multiphase, staff training program delivered over 6 months, including: an off-site workshop emphasizing team dynamics, problem solving, and the use of performance feedback data; and action plans for process improvement; and telephone and videoconference consultations. Control and intervention teams received site-specific team performance profiles with recommendations to use this information to modify team process.

Main Outcome Measures

Three patient outcomes: functional improvement as measured by the change in motor items of the FIM instrument, community discharge, and length of stay (LOS).

Results

For both the primary (stroke only) and secondary analyses (all patients), there was a significant difference in improvement of functional outcome between the 2 groups, with the percentage of stroke patients gaining more than a median FIM gain of 23 points increasing significantly more in the intervention group (difference in increase, 13.6%; P=.032). There was no significant difference in LOS or rates of community discharge.

Conclusions

Stroke patients treated by staff who participated in a team training program were more likely to make functional gains than those treated by staff receiving information only. Team based clinicians are encouraged to examine their own team. (ClinicalTrials.gov identifier NCT00237757).     

Diabetes Prevalence and Influence on Resource Use in Washington State Inpatient Rehabilitation Facilities, 2001 to 2007

Weeks DL, Daratha KB, Towle LA. Diabetes prevalence and influence on resource use in Washington State inpatient rehabilitation facilities, 2001 to 2007.

Objective

To determine the prevalence of diabetes in inpatient rehabilitation facilities in Washington State from 2001 to 2007, and to determine the impact of diabetes on length of stay (LOS) and charges per day.

Design

Longitudinal retrospective cohort analysis of inpatient rehabilitation discharge data from the Washington State Department of Health Comprehensive Hospital Abstract Reporting System.

Setting

Inpatient rehabilitation.

Participants

Adults (N=56,382) who were discharged from inpatient rehabilitation in Washington State between 2001 and 2007.

Interventions

Not applicable.

Main Outcome Measures

Evidence of an established diagnosis of diabetes from International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnosis codes; comorbid conditions reported in ICD-9-CM codes; LOS; and charges per stay.

Results

For all discharges from 2001 to 2007, diabetes prevalence was 17.8%; prevalence within specific impairment groups was 21.3% for the stroke subgroup, 14.2% for the orthopedic disorders subgroup, and 25% for the medically complex conditions subgroup. For all discharges, and within each impairment subgroup, prevalence did not change significantly from year to year. When adjusted for burden of nondiabetes comorbidities, LOS was significantly shorter for all discharges with diabetes younger than 65 years. The association between a diabetes codiagnosis and LOS in specific impairment groups was complex, ranging from a significantly shorter LOS for discharges with diabetes in the stroke subgroup to a finding of no significant difference in LOS among discharges with or without diabetes in the orthopedic impairments subgroup. Across all discharges, charges per day from 2003 to 2007 were significantly greater in discharges with diabetes. Within each specific impairment subgroup, charges per day across the entire study period were significantly greater for discharges with diabetes.

Conclusions

The high prevalence of diabetes, coupled with its impact on resource use, suggests that substantial pressures may be placed on the inpatient rehabilitation care system to respond to the needs of those with diabetes.     

Cognitive and Affective Predictors of Rehabilitation Participation After Stroke

Skidmore ER, Whyte EM, Holm MB, Becker JT, Butters MA, Dew MA, Munin MC, Lenze EJ. Cognitive and affective predictors of rehabilitation participation after stroke.

Objective

To examine associations between cognitive and affective impairments and rehabilitation participation during stroke rehabilitation.

Design

Secondary analyses of stroke patients who received acetylcholinesterase inhibitors during inpatient rehabilitation.

Setting

University-affiliated inpatient rehabilitation facilities.

Participants

Patients (N=44) admitted to inpatient stroke rehabilitation with impairment in attention, memory, or executive functions.

Interventions

Secondary analysis of patients receiving inpatient stroke rehabilitation care plus random assignment to one of two acetylcholinesterase inhibitors or no drug at rehabilitation admission.

Main Outcome Measures

Correlations between measures of cognitive (Digit Span, Hopkins Verbal Learning Test, Executive Interview) and affective impairments (Hamilton Rating Scale for Depression, Apathy Evaluation Scale) and participation (Pittsburgh Rehabilitation and Participation Scale) were examined. Significant correlates of participation were examined in a linear multiple regression model.

Results

Executive functions and depressive symptoms were significant correlates of participation. After controlling for baseline disability, executive functions predicted participation, but depressive symptoms did not (F_4,32=9.35; R²=.54, P<.001).

Conclusions

These findings are an important first step toward understanding potentially modifiable clinical factors that contribute to rehabilitation participation and overall functional status after rehabilitation. A better understanding of cognitive impairment and rehabilitation participation may be used to develop strategies for improving functional outcomes after stroke.     

Interrater Reliability of Functional Status Scores for Patients Transferred From One Rehabilitation Setting to Another

Kohler F, Redmond H, Dickson H, Connolly C, Estell J. Interrater reliability of functional status scores for patients transferred from one rehabilitation setting to another.

Objective

To report the interrater reliability of FIM total score, FIM motor subscore, and FIM cognitive subscore from scoring that occurred in routine clinical practice in 2 closely linked inpatient rehabilitation services in Sydney, Australia.

Design

A natural-experiment blind clinical interrater reliability cohort study of the FIM across 2 rehabilitation units.

Setting

This study is set in 2 inpatient rehabilitation units immediately adjacent to each other in southwestern Sydney, New South Wales, Australia.

Participants

All patients (N=143) who were transferred between the 2 rehabilitation units between August 2006 and October 2007 were included in the study.

Intervention

Discharge FIMs were scored by the first unit and an admission FIM was scored independently by the second unit within a few days. The FIM scores were analyzed for agreement and systematic bias.

Main Outcome Measure

Intraclass correlation coefficients, kappa statistic, weighted kappa statistic, and Bland-Altman plots were used.

Results

There were 143 sets of scores identified. The range of differences between the 2 FIM totals was −32 to 50, between the FIM motor subscores was −22 to 43, and between the FIM cognitive subscores was −14 to 21. Bland-Altman plots demonstrated poor agreement. Few FIM totals were perfectly matched. The intraclass correlation coefficients ranged from .872 for the FIM total to .830 for the cognitive subscales. Values for kappa ranged from −.007 (FIM motor subscore) to .123 (FIM cognitive subscore). Values for weighted kappa ranged from .465 (FIM cognitive subscore) to .521 (FIM total).

Conclusions

There was no systematic scoring bias evident. Intraclass correlation coefficients were high, but tests of agreement demonstrated poor agreement. These findings have implications for the use of the FIM and any patient classification or funding system based on the FIM, especially if poor levels of agreement were found in the presence of all staff being FIM credentialed and standardization of methods of assessment. This study indicates that further investigation of agreement of both FIM totals and FIM item scores in the clinical setting is warranted.     

Impact of comorbidities on stroke rehabilitation outcomes: does the method matter?

Berlowitz DR, Hoenig H, Cowper DC, Duncan PW, Vogel WB. Impact of comorbidities on stroke rehabilitation outcomes: does the method matter?

Objectives

To examine the impact of comorbidities in predicting stroke rehabilitation outcomes and to examine differences among 3 commonly used comorbidity measures—the Charlson Index, adjusted clinical groups (ACGs), and diagnosis cost groups (DCGs)—in how well they predict these outcomes.

Design

Inception cohort of patients followed for 6 months.

Setting

Department of Veterans Affairs (VA) hospitals.

Participants

A total of 2402 patients beginning stroke rehabilitation at a VA facility in 2001 and included in the Integrated Stroke Outcomes Database.

Interventions

Not applicable.

Main Outcome Measures

Three outcomes were evaluated: 6-month mortality, 6-month rehospitalization, and change in FIM score.

Results

During 6 months of follow-up, 27.6% of patients were rehospitalized and 8.6% died. The mean FIM score increased an average of 20 points during rehabilitation. Addition of comorbidities to the age and sex models improved their performance in predicting these outcomes based on changes in c statistics for logistic and R² values for linear regression models. While ACG and DCG models performed similarly, the best models, based on DCGs, had a c statistic of .74 for 6-month mortality and .63 for 6-month rehospitalization, and an R² of .111 for change in FIM score.

Conclusions

Comorbidities are important predictors of stroke rehabilitation outcomes. How they are classified has important implications for models that may be used in assessing quality of care.     

Predictors of Extended Rehabilitation Length of Stay After Traumatic Brain Injury

Arango-Lasprilla JC, Ketchum JM, Cifu D, Hammond F, Castillo C, Nicholls E, Watanabe T, Lequerica A, Deng X. Predictors of extended rehabilitation length of stay after traumatic brain injury.

Objective

To develop a prediction rule for acutely identifying patients at risk for extended rehabilitation length of stay (LOS) after traumatic brain injury (TBI) by using demographic and injury characteristics.

Design

Retrospective cohort study.

Setting

Traumatic Brain Injury Model Systems.

Participants

Sample of TBI survivors (N=7284) with injuries occurring between 1999 and 2009.

Interventions

Not applicable.

Main Outcome Measures

Extended rehabilitation LOS defined as 67 days or longer.

Results

A multivariable model was built containing FIM motor and cognitive scores at admission, preinjury level of education, cause of injury, punctate/petechial hemorrhage, acute-care LOS, and primary payor source. The model had good calibration, excellent discrimination (area under the receiver operating characteristic curve = .875), and validated well. Based on this model, a formula for determining the probability of extended rehabilitation LOS and a prediction rule that classifies patients with predicted probabilities greater than 4.9% as at risk for extended rehabilitation LOS were developed.

Conclusions

The current predictor model for TBI survivors who require extended inpatient rehabilitation may allow for enhanced rehabilitation team planning, improved patient and family education, and better use of health care resources. Cross-validation of this model with other TBI populations is recommended.     

Hemispatial Neglect and Rehabilitation in Acute Stroke

Cumming TB, Plummer-D'Amato P, Linden T, Bernhardt J. Hemispatial neglect and rehabilitation in acute stroke.

Objectives

To compare 2 methods for determining neglect in patients within 2 days of stroke, and to investigate whether early neglect was related to rehabilitation practice, and whether this relationship was affected by an early, intensive mobilization intervention.

Design

Data were collected from patients participating in a phase II randomized controlled trial of early rehabilitation after stroke.

Setting

Acute hospital stroke unit.

Participants

Stroke patients (N=71).

Intervention

The 2 arms of the trial were very early mobilization (VEM) and standard care (SC).

Main Outcome Measures

Neglect was assessed using the Star Cancellation Test and the National Institutes of Health Stroke Scale (NIHSS) inattention item within 48 hours of stroke onset, and therapy details were recorded during the hospital stay.

Results

Assessing neglect so acutely after stroke was difficult: 29 of the 71 patients were unable to complete the Star Cancellation Test, and agreement between this test and the NIHSS measure was only .42. Presence of neglect did not preclude early mobilization. SC group patients with neglect had longer hospital stays (median, 11d) than those without neglect (median, 4d); there was no difference in length of stay between patients with and without neglect in the VEM group (median, 6d in both).

Conclusion

Early mobilization of patients with neglect was feasible and may contribute to a shorter acute hospital stay.     

Hospital disposition after stroke in a national survey of acute cerebrovascular diseases in Israel

Treger I, Ring H, Schwartz R, Tsabari R, Bornstein NM, Tanne D; for the National Acute Stroke Israeli Survey Group. Hospital disposition after stroke in a national survey of acute cerebrovascular diseases in Israel.

Objective

To investigate predictive factors for disposition after acute stroke.

Design

A nationwide survey (2004 National Acute Stroke Israeli Survey).

Setting

All 28 primary general medical centers operating in Israel.

Participants

Acute stroke patients (n=1583) admitted during February and March 2004 and discharged from the primary hospital.

Interventions

Data collected on baseline characteristics, stroke presentation, type and severity, in-hospital investigation and complications, discharge disability, acute hospital disposition, and mortality follow-up.

Main Outcome Measure

Hospital disposition to home, acute rehabilitation, or nursing facility.

Results

Among patients, 58.9% (n=932) were discharged home, 33.7% (n=534) to rehabilitation departments, and only 7.4% (n=117) to nursing facilities. Admission neurologic status was a good predictor of hospital disposition. Patients with severe strokes were mostly discharged to rehabilitation facilities. Patients with significant functional decline before the index stroke, resulting from a previous stroke or another cause, were sent to inpatient rehabilitation less frequently. Disability level at discharge from acute hospitalization had high predictive value in hospital disposition after stroke. In the northern region of Israel, a higher proportion of patients were sent home and a lower proportion to rehabilitation and nursing facilities, probably because of lower availability of rehabilitation care in this region of Israel.

Conclusions

This nationwide survey shows that most stroke survivors in Israel are discharged home from the acute primary hospital. Good functional status before the index stroke is an important predictor for being sent to acute inpatient rehabilitation. Severity of neurologic impairment and level of disability after the stroke at discharge from the primary hospital are strong predictors for disposition after stroke in Israel. Our data may be useful in discharge planning for stroke patients by policy-makers and health care providers in Israel.     

Comparison of the Responsiveness of the FIM and the interRAI Post Acute Care Assessment Instrument in Rehabilitation of Older Adults

Glenny C, Stolee P, Husted J, Thompson M, Berg K. Comparison of the responsiveness of the FIM and the interRAI Post Acute Care Assessment Instrument in rehabilitation of older adults.

Objective

To compare the responsiveness of 2 major systems developed for rehabilitation settings—the FIM and the interRAI Post Acute Care (PAC) assessment—in older patients.

Design

Trained raters assessed patients with both tools at admission and discharge.

Setting

Musculoskeletal (MSK) and geriatric rehabilitation units (GRUs) in 2 rehabilitation hospitals.

Participants

Older adults receiving rehabilitation (N=208; mean age ± SD, 78.5±9.3; 67% women).

Interventions

Not applicable.

Main Outcome Measures

Responsiveness was evaluated using effect size (ES) and standardized response mean (SRM).

Results

ES and SRM were somewhat higher for the FIM motor (GRU ES=1.68, SRM=1.31; MSK ES=2.12, SRM=2.25) than the PAC (GRU ES=1.64, SRM=1.29; MSK ES=1.57, SRM=1.89) in both patient groups. Both tools were more responsive in MSKs than GRUs. This may reflect the greater frailty and clinical complexity of GRU patients.

Conclusions

Both the FIM motor and the PAC were able to detect clinically relevant improvement in functional ability in older rehabilitation inpatients.     

Pain in persons with postpolio syndrome: frequency, intensity, and impact

Stoelb BL, Carter GT, Abresch RT, Purekal S, McDonald CM, Jensen MP. Pain in persons with postpolio syndrome: frequency, intensity, and impact.

Objective

To describe the frequency, intensity, and impact of pain in persons with postpoliomyelitis syndrome (PPS).

Design

Retrospective, cross-sectional survey.

Setting

Community-based survey.

Participants

Convenience sample of people with PPS.

Interventions

Not applicable.

Main Outcome Measures

Overall intensity and duration of pain, pain sites, pain interference, pain treatments, and relief provided by pain treatments.

Results

A total of 91% (n=57) of the study participants (N=63) reported pain. The most frequently reported pain sites were the shoulders, lower back, legs, and hips. Participants reported pain intensity to be the greatest in the knees, legs, wrists, lower back, and head. Pain interfered most with sleep and with activities requiring a high level of musculoskeletal involvement. Respondents also reported pain problems that were more severe than those of the general population and than those of a sample of people with multiple sclerosis. Many treatments had been tried previously for pain, but continued use of treatments was reported by relatively few participants at the time of the survey.

Conclusions

The findings indicate that pain is a persistent and common problem in persons with PPS, highlighting the need for effective and accessible pain treatments for this population.     

Action Observation Treatment Improves Recovery of Postsurgical Orthopedic Patients: Evidence for a Top-Down Effect?

Bellelli G, Buccino G, Bernardini B, Padovani A, Trabucchi M. Action observation treatment improves recovery of postsurgical orthopedic patients: evidence for a top-down effect?

Objective

To assess whether action observation treatment (AOT) may also improve motor recovery in postsurgical orthopedic patients, in addition to conventional physiotherapy.

Design

Randomized controlled trial.

Setting

Department of rehabilitation.

Participants

Patients (N=60) admitted to our department postorthopedic surgery were randomly assigned to either a case (n=30) or control (n=30) group. Exclusion criteria were age 18 years or younger and 90 years or older, Mini-Mental State Examination score of 21 of 30 or lower, no ambulating order, advanced vision impairment, malignancy, pneumonia, or heart failure.

Interventions

All participants underwent conventional physiotherapy. In addition, patients in the case group were asked to observe video clips showing daily actions and to imitate them afterward. Patients in the control group were asked to observe video clips with no motor content and to execute the same actions as patients in the case group afterward. Participants were scored on functional scales at baseline and after treatment by a physician blinded to group assignment.

Main Outcomes Measures

Changes in FIM and Tinetti scale scores, and dependence on walking aids.

Results

At baseline, groups did not differ in clinical and functional scale scores. After treatment, patients in the case group scored better than patients in the control group (FIM total score, P=.02; FIM motor subscore, P=.001; Tinetti scale score, P=.04); patients in the case group were assigned more frequently to 1 crutch (P=.01).

Conclusions

In addition to conventional physiotherapy, AOT is effective in the rehabilitation of postsurgical orthopedic patients. The present results strongly support top-down effects of this treatment in motor recovery, even in nonneurologic patients.     

Rehabilitation Outcomes in a Population of Nonagenarians and Younger Seniors With Hip Fracture, Heart Failure, or Cerebral Vascular Accident

Conner D, Barnes C, Harrison-Felix C, Reznickova N. Rehabilitation outcomes in a population of nonagenarians and younger seniors with hip fracture, heart failure, or cerebral vascular accident.

Objectives

To compare rehabilitation characteristics and patient outcomes between nonagenarians and younger seniors with hip fracture (HFx), heart failure (HF), or cerebral vascular accident (CVA).

Design

Data only, retrospective cohort.

Setting

Seven skilled nursing facilities providing rehabilitation services to a managed care organization.

Participants

Subjects (N=2563; age, ≥65y) with HFx, HF, or CVA receiving rehabilitation services.

Interventions

Not applicable.

Main Outcome Measures

Patient and rehabilitation characteristics influencing FIM score at discharge and the proportion of patients discharged to the community were compared between nonagenarians and younger seniors with HFx, HF, or CVA.

Results

Patients with higher admission FIM scores were discharged with better function. Different patient characteristics were important for successful rehabilitation for different conditions and outcomes. Except for HFx, nonagenarians had admission and discharge characteristics similar to those of younger seniors, although fewer were discharged to the community. Nonagenarians and younger seniors with CVA were most similar for all measures.

Conclusions

Fewer nonagenarians were admitted from the community and fewer were discharged to the community, even if admitted from the community. Nonagenarians with HFx differed most strikingly from their younger counterparts in admission and discharge measures, as well as total discharge FIM score and discharge to the community. Nonagenarians and younger seniors with CVA were most similar for all measures. Our results suggest that a large proportion of the nonagenarian population can benefit from rehabilitation efforts for these 3 conditions; however, more rehabilitation resources may be required for some conditions to achieve similar outcomes.     

Sleep-Disordered Breathing in Patients Enrolled in an Inpatient Stroke Rehabilitation Program

Brooks D, Davis L, Vujovic-Zotovic N, Boulias C, Ismail F, Richardson D, Goldstein RS. Sleep-disordered breathing in patients enrolled in an inpatient stroke rehabilitation program.

Objective

To report the prevalence of sleep-disordered breathing in an inpatient stroke rehabilitation unit and to explore correlations with functional status and health-related quality of life.

Design

Cross-sectional study.

Setting

Rehabilitation center.

Participants

Consecutive patients (N=45; mean age, 67±12y) (28 men) enrolled in inpatient rehabilitation after ischemic (84%) or hemorrhagic stroke (16%).

Interventions

Not applicable.

Main Outcome Measures

Overnight respiratory polysomnography was performed on all subjects. Interviewer-administered scales of sleepiness (Epworth Sleepiness Scale) and functional status (FIM, Barthel Index) were completed. Health-related quality of life was assessed by using a general questionnaire (Medical Outcomes Study 36-Item Short-Form Health Survey [SF-36]).

Results

Of the 45 subjects tested, only 4 (9%) had an apnea-hypopnea index of less than 10 per hour. The mean apnea-hypopnea index was 32.2 (19.4) per hour; most events were obstructive. There was no relationship between the respiratory index and the components of SF-36 (P values>.2).

Conclusions

There was a dramatically high prevalence of respiratory events in patients after stroke enrolled in an inpatient stroke rehabilitation unit. The awareness of this will influence patient evaluation and management.
