Nurse staffing and patient outcomes in inpatient rehabilitation settings.

In rehabilitation nursing, the patient classification systems or acuity models and nurse-staffing ratios are not supported by empirical evidence. Moreover there are no studies published characterizing nursing hours per patient day, proportion of RN staff and impact of agency nurses in inpatient rehabilitation settings. The purpose of this prospective observational study was to describe rehabilitation nurse staffing patterns, to validate the impact of rehabilitation nursing on patient outcomes, and to test whether existing patient measures on severity and outcomes in rehabilitation could be used as a proxy for burden of care to predict rehabilitation nurse staffing ceilings and daily nurse staffing requirements. A total of 54 rehabilitation facilities in the United States, stratified by geography, were randomly selected to participate in the study.     

Racial disparities in outcomes of inpatient stroke rehabilitation

OBJECTIVE: To determine whether race is associated with outcomes of inpatient stroke rehabilitation. DESIGN: Retrospective cohort study. SETTING: A community-based inpatient rehabilitation facility. PARTICIPANTS: Poststroke patients (N=1002) admitted to a community-based inpatient rehabilitation facility between 1995 and 2001. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Functional improvement at discharge from the rehabilitation facility, discharge disposition, and functional improvement at 3 months after discharge. Inpatient and follow-up data were collected from the facility's electronic patient database. We used the FIM instrument to assess functional status at admission, discharge, and follow-up. RESULTS: In multivariable models, blacks achieved less functional improvement at discharge (-1.9 FIM points, P=.02) compared with whites and, despite worse FIM scores, were more likely to be discharged to home (adjusted odds ratio=1.7; 95% confidence interval, 1.1-2.5). Although Asian-American patients did not differ from whites in terms of functional improvement at discharge or disposition, they had less improvement at 3 months following discharge (-6.3 FIM points, P=.005). CONCLUSIONS: We identified racial disparities in poststroke outcomes in a community-based inpatient rehabilitation facility. Future research in stroke rehabilitation should explore the consistency of these findings across settings and if they are confirmed, identify explanatory mediators to better inform efforts to eliminate racial disparities.     

Management of diabetes during acute stroke and inpatient stroke rehabilitation

OBJECTIVES: To summarize evidence on the impact of hyperglycemia on stroke outcomes and to present therapy algorithms for inpatient management in diabetic stroke patients. DATA SOURCES: Guidelines for inpatient management of diabetes were reviewed and extracted from a technical review and recommendations from 2 national diabetes and endocrine organizations. MEDLINE database searches were conducted using key words: stroke, diabetes, hyperglycemia, hypoglycemia, inpatient, hospitalized, treatment, outcomes, disability, self-management, and education. STUDY SELECTION: Studies were selected that specifically addressed the impact of the following in stroke patients: hyperglycemia and diabetes on rehabilitation outcomes, management strategies for hyperglycemia and diabetes, and strategies for facilitating diabetes self-management. DATA EXTRACTION: Two authors independently extracted data and management practices from selected articles and published practice guidelines. DATA SYNTHESIS: Diabetes is prevalent in stroke patients and results in poorer inpatient hospital and rehabilitation outcomes. Management of diabetes in stroke patients is further complicated by impairments in mobility and vision, necessitating accommodation strategies and tools for self-management. Optimal management of hyperglycemia using insulin or oral hypoglycemic agents results in reduced morbidity and mortality among diabetic inpatients. CONCLUSIONS: To achieve inpatient glycemic management targets, use of clinical management algorithms, self-management tools, and systems approaches such as diabetes management teams are useful.     

Measuring patient-reported outcomes after discharge from inpatient rehabilitation settings.

OBJECTIVE: To examine the sensitivity of the Short Form Activity Measure for Post-Acute Care (AM-PAC) in comparison to the Functional Independence Measure (FIM) across a 12-month period after discharge from rehabilitation hospital. DESIGN: Prospective longitudinal study. Patients were recruited while receiving inpatient services from facilities in the north-east USA and interviewed 1, 6 and 12 months thereafter. PATIENTS: Convenience sample of 516 patients at baseline (65% retention at the final follow-up) receiving rehabilitation services for neurological, lower extremity orthopedic, or complex medical conditions. Mean age 68.3 years; 47% male. MAIN OUTCOME MEASURES: AM-PAC Physical and Movement, Personal Care and Instrumental, and Applied Cognitive Activity scales; FIM Motor and Cognitive scales. RESULTS: All 3 AM-PAC scales were sensitive to both positive and negative change across the follow-up period. Standardized response means for the AM-PAC were consistently larger than for the FIM across patient and severity groups. A greater percentage of patients showed positive change that exceeded the minimal detectable change on the AM-PAC than on the FIM both 6- and 12-month follow-ups. CONCLUSION: The short-form AM-PAC scales are more sensitive measures of change in functional activity performance over time in the general population of persons who receive inpatient rehabilitation services compared to the FIM. Thus, the AM-PAC offers a short, comprehensive, and sensitive measure of positive and/or negative change in patients' ability to perform important activities of daily life.     

Use of outcomes information in acute inpatient rehabilitation

OBJECTIVE: To describe the ways in which rehabilitation outcomes information is used in the acute inpatient rehabilitation industry and the industry's views on the topic of public disclosure of rehabilitation outcomes information. DESIGN: A mixed-methods approach, featuring data from 39 informational telephone interviews with rehabilitation industry stakeholders followed by a survey of 95 randomly sampled acute inpatient rehabilitation provider organizations. RESULTS: Both the informational interviews and survey findings revealed that there is currently little stakeholder demand for functional outcomes information. Outcomes information is primarily used within provider organizations to track the effectiveness of rehabilitation services. There is general consensus among rehabilitation provider organizations in favor of public disclosure of outcomes information. CONCLUSIONS: Outcomes information is not routinely shared with rehabilitation stakeholders (i.e., payers and consumers). Rehabilitation providers and industry stakeholders generally express favorable attitudes toward public disclosure of outcomes information. Stakeholders' perceptions of current barriers and facilitators of outcomes information provide insight into the steps that can be taken toward greater transparency in the rehabilitation industry.     

Rehabilitation outcomes in patients with brain tumors and acute stroke: comparative study of inpatient rehabilitation

OBJECTIVES: To investigate functional outcomes after hospital rehabilitation of patients surviving craniotomy for primary brain tumor excision compared with post-stroke patients. DESIGN: The database of the Neurological Rehabilitation Department "C" of Loewenstein Rehabilitation Center was used to investigate primary brain tumors and first ischemic and hemorrhagic stroke patients admitted for hospital rehabilitation during an 11-yr period, between January 1993 and August 2004. Particular attention was paid to age and sex distribution, onset-to-admission interval, length of stay, functional status at admission and discharge, functional gain (DeltaFI change) as measured by the FIM instrument. RESULTS: A total of 168 patients with craniotomy for primary brain tumor excision (128 intracranial meningiomas and 40 cerebral gliomas) and 1660 first-stroke patients were admitted to the department for rehabilitation during the study period. Mean patient age was 59.9 yrs in meningioma group, 54.1 yrs in the glioma group, and 60.4 yrs in the stroke group. In the meningioma and stroke groups, male patients were in the majority (62 and 70%); in the glioma group, there was equal sex distribution. On average, patients were admitted to rehabilitation treatment 13 days after meningioma excision, 34 days after glioma operation, and 21.6 days after stroke. Functional variables during inpatient rehabilitation were found to be similar in the all groups. Average FIM rating at admission was 80.07 in the meningioma group, 68.2 in the glioma group, and 70.4 in the stroke group. Average discharge FIM rating was 90.3 for patients with meningiomas, 80.7 for patients with gliomas, and 87.8 for stroke patients. Functional gain was 17.9 for meningioma patients, 17.2 for glioma patients, and 21.8 for stroke patients. Average length of stay was 24 days for the meningioma group, 23 days for the glioma group, and 75.4 days for stroke patients; 88.1% of stroke patients, 91.7% of meningioma patients, and 82.7% of glioma patients were discharged to their homes, and 5.4, 3.4, and 8.6%, respectively, were discharged to nursing homes. CONCLUSIONS: Patients with brain tumors can achieve good functional outcomes with a shorter length of stay.     

Long-term effects of the intensification of the transition between inpatient neurological rehabilitation and home care of stroke patients

OBJECTIVE: To investigate an intensified transition concept between neurological inpatient rehabilitation and home care for long-term effects on the care situation two and a half years after stroke patients' discharge. DESIGN: Controlled clinical trial allocating patients to intervention group (intensified transition on ward II) or control group (standard transition on ward I); patients were allocated to whichever ward had a vacancy. The last follow-up assessment was carried out on average 31 months after discharge. INTERVENTION: The intensified transition concept consisted of therapeutic weekend care, bedside teaching and structured information for relatives during the second phase of the rehabilitation. SUBJECTS: Seventy-one patients and their family carers were included, of which one case dropped out. Therefore 70 family carers--35 individuals in each group-- were available for assessment at long-term follow-up. DATA COLLECTION: Family carers were asked via telephone whether the patient was still alive and if so, where he or she is living--at home or in a nursing home. Statistical methods: Binary logistic regression analysis with the care situation (home care versus institutionalized care or deceased) as dependent variable. RESULTS: Two and a half years after discharge (T3) in the intervention group significantly fewer patients were institutionalized (2 versus 5) or deceased (4 versus 11) (P = 0.010). Multivariate analysis showed that besides a higher functional life quality at discharge and lower patient's age, the participation in the intensified transition programme is the third significant predictor for home care at T3. CONCLUSION: Effects of an intensified transition programme can persist over a long-term period. They can sustain home care by reducing institutionalization and mortality.     

Outcomes of speech-language pathology following stroke: Investigation of inpatient rehabilitation and rehabilitation in the home programs

Speech-language pathology outcomes following stroke are poorly understood, and potential predictors of these, such as age and therapy input have not been well documented. For 12 months, the Australian Therapy Outcome Measures (AusTOMs) for Speech Pathology scales were used to rate swallowing and language outcomes for patients (n = 63) receiving rehabilitation post stroke. Outcomes were compared by service type (inpatient versus home based), amount of input and patient age. Greatest improvement was seen on the Swallowing scale. There was no difference in outcomes of inpatients compared to home based rehabilitation patients. There was a trend towards better outcomes with increasing input for the Swallowing scale and for Participation Restriction and Distress/Wellbeing domains. Patients less than 75 years of age had better Participation Restriction and Distress/Wellbeing outcomes, compared to older patients. These results align with previous studies, suggesting that inpatient and home based service models may be equally effective post stroke. Therapy input and patient age were related to some, but not all, domains of the AusTOMs, and these results may have implications for patient management. They should also direct future research to further explore these relationships; for example, to identify optimal input to achieve best outcomes.     

Racial disparities in stroke functional outcomes upon discharge from inpatient rehabilitation facilities

Purpose.?Analyse racial disparities in clinical outcomes after stroke in inpatient rehabilitation facilities (IRF).

Methods.?Analyses based on data from a multi-center prospective observational cohort study on inpatient stroke rehabilitation in six IRFs from across the United States. Multivariate models examined racial disparities in functional outcomes upon discharge, taking into account patient characteristics and detailed information on processes of care.

Results.?In the moderate stroke group (N?=?397), functional scores on admission were not significantly different between African-Americans and whites. In the severe stroke group (N?=?335), whites showed significantly lower functional scores at admission [Functional Independence Measurement, (FIM)], mean scores, 44 versus 49 for African-Americans, p?<?0.001). Multivariate analyses predicting discharge motor FIM score found no significant differences between African-American and white stroke patients (p?=?0.2194 and p?=?0.3547 in the moderate and severe stroke group, respectively).

Conclusion.?Controlling for patient characteristics, therapy intensity and processes of care results in non-significant differences between African-Americans and whites in motor FIM scores upon discharge. The absence of significant differences in recovery while patients were on the rehabilitation unit suggests that racial disparities in long-term functional recovery after stroke are likely to have originated before or after the inpatient rehabilitation stay.     

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.     

The impact of the inpatient rehabilitation facility prospective payment system on stroke program outcomes

OBJECTIVE: To examine the impact of the Medicare inpatient rehabilitation facility (IRF) prospective payment system (PPS) on outcomes in a stroke rehabilitation program. DESIGN: An analysis was performed on a database including 945 stroke patients admitted to an inpatient stroke rehabilitation program 5 yrs before implementation of the IRF PPS and 3.5 yrs after implementation. Patients were classified with regard to stroke location (left vs. right), level of cognitive impairment, presence/absence of unilateral neglect, and level of depressive symptomatology. Functional status was evaluated at time of admission and discharge by functional independence measure (FIM). Other outcome measures included length of stay (LOS) and discharge destination. The impact of IRF PPS on LOS, progress in rehabilitation, and discharge destination was examined via univariate analyses of covariance and logistic regression. RESULTS: Patients admitted after implementation of the IRF PPS had shorter LOS but made less progress, had lower functional levels at discharge, and had higher rates of institutional discharge. CONCLUSIONS: Although associated with decreased LOS, implementation of the IRF PPS was associated with decreased functional gains, lower discharge FIM levels, and higher rates of institutional discharge. Cost savings associated with the PPS must be considered in light of these untoward outcomes.     

Assessment chart for inpatient rehabilitation following stroke

In order to enable comparison of the post-stroke patient's functional status between different points during the rehabilitation process, an assessment chart was developed; this covered cognitive, basic and integrated functions. The chart was applied by two independent examiners on 36 patients, with a mean age of 60, admitted consecutively for rehabilitation following stroke. The results of the assessment using the chart were compared with those measured with the Kenny Self Evaluation System. There was a positive correlation both between the Kenny System and the developed chart and the two examiners. It is felt that the chart meets the demands of easy applicability, numerical scoring and comprehensiveness. It is sufficiently sensitive to reflect the progress of patients during rehabilitation and enables re-evaluation of initial treatment plans focusing on the needs of the individual patient. The developed chart may serve as a useful tool in the evaluation of stroke inpatients during their rehabilitation.     

The impact of diabetes mellitus on stroke acute rehabilitation outcomes

OBJECTIVE: To examine the impact of diabetes mellitus (DM) on functional outcomes after acute rehabilitation for cerebrovascular accident (CVA). DESIGN: A retrospective research design was used to analyze outcomes in patients with a primary diagnosis of unilateral stroke (n = 367) admitted to an urban, acute rehabilitation center in the Southeastern United States. RESULTS: Multivariable hierarchical regression revealed that DM did not contribute statistically significant variance to stroke acute rehabilitation prediction models. Rehabilitation admission functioning scores, rehabilitation length of stay, age, and stroke type were significant predictors of poststroke rehabilitation motor outcomes (r2 = 0.603) and cognitive outcomes (r2 = 0.712). Diabetes also had no significant impact on acute stroke rehabilitation lengths of stay or rehabilitation discharge setting. CONCLUSIONS: Diabetes does not seem to significantly impact short-term acute rehabilitation outcomes after stroke. Persons with diabetes who suffer a stroke seem to benefit and improve during their acute rehabilitation stay at levels equivalent to peers who are not diagnosed with diabetes. Future research should examine the impact of diabetes subtypes and undiagnosed diabetes on short- and long-term outcomes.     

Selection for inpatient rehabilitation after acute stroke: a systematic review of the literature

Hakkennes SJ, Brock K, Hill KD. Selection for inpatient rehabilitation after acute stroke: a systematic review of the literature.

Objective

To identify patient-related factors that have been found to correlate with functional outcomes post acute stroke to guide clinical decision making with regard to rehabilitation admission after acute stroke.

Data Sources

We systematically searched the scientific literature between 1966 and January 2010. The primary source of studies was the electronic databases Medline, CINAHL, and Embase. The search was supplemented with citation tracking.

Study Selection

Two reviewers independently applied the inclusion criteria to identify relevant articles from the citations obtained through the literature search. Eligible studies included systematic reviews of prognostic indicators, studies of prognostic indicators of acute discharge disposition, and studies of rehabilitation admission criteria after acute stroke. Of the 8895 studies identified, 83 articles, representing 79 studies, were included in the review.

Data Extraction

One reviewer extracted the data relating to the participants, prognostic indicators, and outcomes. A second reviewer independently checked data extracted with disagreement resolved by a third reviewer. Quality of included studies was assessed for internal and external validity.

Data Synthesis

Of the 79 studies, 26 were systematic reviews of prognostic indicators of functional level and/or discharge disposition, 48 were studies of prognostic indicators of acute discharge disposition, and 6 were studies of rehabilitation selection criteria. The methodologic quality of the included studies was generally poor. Age, cognition, functional level after stroke, and, to a lesser extent, continence were found to have a consistent association with outcome across all 3 research areas. In addition, stroke severity was also associated with acute discharge disposition, final discharge disposition, and functional level. Sex and side of stroke appeared to have no association across all 3 of the research areas.

Conclusions

This review highlights a number of important prognostic indicators and rehabilitation selection criteria that may assist clinicians in improving selection procedures and standardizing access to inpatient rehabilitation after stroke, although the quality of many studies is low. Further high quality studies and reviews of prognostic indicators and clinician decision making with regards to rehabilitation acceptance are required.     

Clinical and administrative outcomes during publicly-funded inpatient stroke rehabilitation based on a case-mix group classification model.

OBJECTIVES: To determine efficiency and efficacy of publicly-funded inpatient stroke rehabilitation based on a Case-Mix Group Classification Model, and to analyse the usefulness of this decisional aid in the refinement of rehabilitation services delivery needed to optimize accessibility to inpatient rehabilitation services for individuals with stroke in a publicly-funded healthcare system. DESIGN: Individuals with stroke (n=422) who received inpatient rehabilitation through the Montreal Rehabilitation Hospital Network were included in this retrospective study. Clinical (total, motor and cognitive-Functional Independence Measure (FIM) scores, percentage of discharge to community) and administrative outcomes (onset to rehabilitation interval, length of inpatient rehabilitation stay, length of stay efficiency) were measured. RESULTS: Across Case-Mix Groups, mean onset to rehabilitation days varied between 16.2 (5.7) and 32.0 (19.4) days whereas the mean length of stay fluctuated between 27.5 (13) and 77.0 (27) days. Best total (41.6 (21.4)) and motor-FIM (38.9 (19.0)) gains were observed in most severely disabled cases (114) whereas the Case-Mix Group 103 presented the best cognitive-FIM gain (5.8 (4.0)). Optimal mean total, motor and cognitive-FIM efficiency rates, found in moderately disabled stroke patients, were 0.668 (0.434), 0.634 (0.377) and 0.15 (0.136), respectively. Majority of patients returned home following rehabilitation in all Case-Mix Groups (63.6% to 96.4%) except for groups 112 and 108. CONCLUSION: Moderate to good length of stay efficiencies are observed among all Case-Mix Group following stroke rehabilitation. In fact, individuals with moderate disability present the best rate of recovery. Variations in length of stay efficiency suggest that the use of a Case-Mix Group Classification Model in stroke rehabilitation could represent an innovative approach, especially for program evaluation in publicly-funded and universal-access rehabilitation hospitals.     

A home rehabilitation program for stroke patients

The purpose of this study was to develop a rehabilitation program wherein the stroke team, patient and family act as partners in the rehabilitation process initially at hospital and subsequently on discharge for 4 weeks in the stroke patient's home. The study attempted to address the stroke patient's functional ability and life satisfaction from a holistic viewpoint. A quasi-experimental design was used. Thirty-two stroke patients participated in the intervention group and nine in the control group. The intervention group improved in functional ability after 4 weeks at home. They also participated in activities and were generally more active than the control group. Ninety percent of the families in the intervention group experienced high life satisfaction levels after the training period. However this satisfaction decreased after 6 months, and one year post-stroke, the patient and family's life satisfaction levels increased once more. It is likely that being given the opportunity to make one's own decisions, to be more active and motivated led to improvements in patients' daily life functions as they were able to carry out their preferred activities in the comfort of their own home. The program shortened the admission time for the intervention group by one-third.     

Relationship between call light use and response time and inpatient falls in acute care settings

Aims and objectives. This exploratory study used archived hospital data to determine whether the call light use rate and the average call light response time contribute to the fall and the injurious fall rates in acute care settings. Background. Inpatients often use call lights to seek nurses’ attention and assistance. Although implied in patient safety, no studies have examined data related to the call light use or the response time to call lights collected via existing tracking mechanisms to monitor nursing practice. Design. The study was conducted in a Michigan community hospital and used archived hospital data for analyses for the period from February 2007–June 2008. The unit of analysis was unit‐week. Method. The call light use rate per patient‐day was calculated based on information retrieved from the call light tracking system. The average response time in seconds was used as generated from the tracking system. The fall and injurious fall rates per 1000 patient‐days were calculated based on the fall incident reports. spss was used for data analyses. One‐way anova and correlation analyses were conducted. Results. More calls for assistance related to less fall‐related patient harm. Surprisingly, longer response time to call lights also related to fewer total falls and less fall‐related patient harm. Generally speaking, more call light use related to longer response times. Conclusions. This study’s findings challenged the appropriateness of targeting the goals of reducing the frequency of call light use and the fall rates as two outcome indicators of conducting hourly patient rounds. Relevance to clinical practice. Encouraging call light use is a key to reducing injurious fall rates. Unit managers should routinely monitor the trend of the call light use rate and ensure that the call light use rate is maintained at least above the mean rate.     

Length of stay benchmarks for inpatient rehabilitation after stroke

Purpose: In Canada, no standardized benchmarks for length of stay (LOS) have been established for post-stroke inpatient rehabilitation. This paper describes the development of a severity specific median length of stay benchmarking strategy, assessment of its impact after one year of implementation in a Canadian rehabilitation hospital, and establishment of updated benchmarks that may be useful for comparison with other facilities across Canada. Method: Patient data were retrospectively assessed for all patients admitted to a single post-acute stroke rehabilitation unit in Ontario, Canada between April 2005 and March 2008. Rehabilitation Patient Groups (RPGs) were used to establish stratified median length of stay benchmarks for each group that were incorporated into team rounds beginning in October 2009. Benchmark impact was assessed using mean LOS, FIM^® gain, and discharge destination for each RPG group, collected prospectively for one year, compared against similar information from the previous calendar year. Benchmarks were then adjusted accordingly for future use. Results: Between October 2009 and September 2010, a significant reduction in average LOS was noted compared to the previous year (35.3 vs. 41.2 days; p < 0.05). Reductions in LOS were noted in each RPG group including statistically significant reductions in 4 of the 7 groups. As intended, reductions in LOS were achieved with no significant reduction in mean FIM^® gain or proportion of patients discharged home compared to the previous year. Adjusted benchmarks for LOS ranged from 13 to 48 days depending on the RPG group. Conclusions: After a single year of implementation, severity specific benchmarks helped the rehabilitation team reduce LOS while maintaining the same levels of functional gain and achieving the same rate of discharge to the community.

Implications for Rehabilitation

• Efficient post-stroke rehabilitation can help to improve patient outcomes and reduce the financial burden placed on the healthcare system.

• Yet, unnecessarily long lengths of stay in rehabilitation are not in the best interest of the patient and act to increase the cost of care.

• This study illustrates how a length of stay benchmarking system can help to promote efficiency in post-stroke rehabilitation and reduce the cost of care without negatively impacting patient recovery.
