Factors Related to Greater Functional Recovery after Suffering a Stroke

Do facilitators and barriers to community ambulation differ among stroke survivors in low resource settings? A cross-sectional study in Nigeria

PURPOSE

Stroke survivors (SSV) in many low- and middle-income countries experience frustrating participation restriction in community ambulation (CA), which impedes community life. This study assessed facilitators and barriers to CA among community-dwelling SSV in a southwest state of Nigeria.

METHODS

This cross-sectional study involved 66 community-dwelling ambulating SSV, purposively recruited from physiotherapy out-patient clinics of selected hospitals in southwest Nigeria. Semi-structured questionnaire containing physical and social environment elements of the ICF domains was administered on respondents. Mobility status at home and community, socio-demographic and clinical data of SSV were also obtained. Responses from open-ended questions were triangulated with appropriate close ended options. Data were analyzed using descriptive statistics and logistic regression at p < 0.05 Alpha value.

RESULTS

Majority of the SSV were independent in their homes (59.1%), used mobility aids (87.9%) and assisted in CA (66.7%). They identified limited physical accessibility by crowds 25 (37.9%), lack of inclined surfaces 40 (95.2%), uneven floors 36 (87.8%), public seating arrangements 33 (78.6%), rain (73.8%) and inability to use services, systems and policies (77.3%) as barriers to CA. Built physical environment was a significant predictor of home (OR = 0.754, p = 0.001) and community mobility (OR = 0.850; p = 0.018), while post-stroke depression was a significant predictor of community mobility (OR = 1.038; p = 0.014).

CONCLUSION

Mobility aids, social attitudes and general support were identified as facilitators, whereas barriers to CA included built physical environment, services and policies, products and technology. Facilitators and barriers to CA are similar to some HIC contexts, perceived difficulties and experiences differ for infrastructural and social reasons among others.

Simplifying venous outflow: Prolonged venous transit as a novel qualitative marker correlating with acute stroke outcomes

BACKGROUND

Prolonged venous transit (PVT), defined as presence of time-to-maximum ≥ 10 s within the superior sagittal sinus (SSS) and/or torcula, is a novel, qualitatively assessed computed tomography perfusion surrogate parameter of venous outflow with potential utility in pretreatment acute ischemic stroke imaging for neuroprognostication. We aim to characterize the correlation between PVT and neurological functional outcomes in thrombectomy-treated patients.

METHODS

A prospectively-collected database of large vessel occlusion acute ischemic stroke patients treated with thrombectomy was retrospectively analyzed. Spearman's rank correlation coefficient and point-biserial correlations were performed between PVT status (i.e., no region, either SSS or torcula, or both), 90-day modified Rankin score (mRS), mortality (mRS 6), and poor functional outcome (mRS 4-6 vs 0-3).

RESULTS

Of 128 patients, correlation between PVT and 90-day mRS (ρ = 0.35, p < 0.0001), mortality (r = 0.26, p = 0.002), and poor functional outcome (r = 0.27, p = 0.002) were significant.

CONCLUSION

There is a modest, significant correlation between PVT and severity of neurological functional outcome. Consequently, PVT is an easily-ascertained, qualitative metric that may be useful as an adjunct for anticipating a patient's clinical course. Future analyses will determine the significance of incorporating PVT in clinical decision-making.

[Factors Modulating Motor Function Changes in Stroke Patients During Inpatient Neurological Rehabilitation]

PURPOSE

To identify factors that have an impact on the degree of functional improvements in stroke patients during inpatient neurological rehabilitation.

METHODS

Retrospective analysis of 398 stroke patients who participated in an inpatient Phase C rehabilitation (Barthel index between 30 and 70 points). We correlated changes in 3 physiotherapeutic assessments (transfer from sitting to standing; transfer from bed to (wheel)chair; climbing stairs) and 3 occupational therapeutic assessments (eating/drinking; dressing of the upper part of the body; object manipulation) with the factors age, gender, Barthel-Index at admission, time since stroke, length of stay in inpatient rehab, number and extent of therapies and ischemic versus hemorrhagic stroke. In addition, a stepwise regression analysis was performed.

RESULTS

The patient group showed significant improvements in all assessments. Length of stay in inpatient rehab and number/extent of therapies correlated with improvements of transfer from sitting to standing, transfer from bed to (wheel)chair, climbing stairs, and dressing of the upper part of the body. Number/extent of therapies also correlated with eating/drinking. Barthel-Index at admission was negatively correlated with transfer from sitting to standing, transfer from bed to (wheel)chair, and dressing of the upper part of the body. No correlation between changes of motor functions and age or gender or type of stroke (ischemic versus hemorrhagic) was found. Patients<3 months after stroke showed stronger improvements of transfer from sitting to standing, transfer from bed to (wheel)chair, climbing stairs, dressing of the upper part of the body, and object manipulation than patients>6 months after stroke. However, patients<3 months after stroke also stayed 10 days longer in inpatient rehab. The stepwise regression analysis identified the number of physiotherapies and Barthel-Index at admission as the most important factors for changes in transfer from sitting to standing and transfer from bed to (wheel)chair, number of physiotherapies and time since stroke for climbing stairs, number of occupational therapies for eating/drinking, number of occupational therapies and time since stroke for dressing the upper part of the body and number of occupational therapies and length of inpatient rehab for object manipulation.

CONCLUSION

In stroke patients, a higher number of therapies is associated with greater improvements of motor functions. Age, gender and type of stroke have no relevant impact on changes of motor functions during inpatient rehabilitation.

Survey of patients with stroke in the Kitakyushu Area, Japan: a 12-year retrospective analysis of the critical pathway

OBJECTIVES

We aimed to clarify the incidence, clinical profile, outcome, and activities of daily living of patients with stroke using the Kitakyushu clinical pathway database and to investigate the characteristics of patients with stroke in the Kitakyushu medical area in Japan.

MATERIALS AND METHODS

The clinical data of patients with stroke registered in the Kitakyushu database between April 1, 2009 and December 31, 2021 were retrospectively examined. The National Institutes of Health Stroke Scale was used to classify stroke severity. A descriptive analysis of basic variables, including age, stroke type, length of hospital stay, and activities of daily living, according to stroke severity was conducted.

RESULTS

There were 7,487 acute care hospital patients and 5,441 rehabilitation hospital patients. Compared with patients in similar cities in Japan, patients in the Kitakyushu area tended to be older at the time of stroke onset with a higher proportion of cases of hemorrhagic stroke. Length of hospital stay in both acute and rehabilitation hospitals increased with stroke severity. The Functional Independence Measure gain was highest in patients with moderate disability.

CONCLUSIONS

Compared with patients in similar cities in Japan, in the Kitakyushu area, patients with stroke were older and the proportion of patients with hemorrhagic stroke was higher. Stroke rehabilitation therapy is effective for patients with moderately severe stroke.

The Measure of an Outcome: Comparing Norming and Stacking to Benchmark the Effectiveness of Brain Injury Rehabilitation Services

Practitioners have a clinical, ethical, academic, and economic responsibility to dispassionately consider how effective their services are. Approaches to measure how "good" or "bad" healthcare is include clinical audit, satisfaction surveys, and routine outcome measurement. However, the process of comparing the clinical outcomes of a specific service against the 'best' services in the same specialism, also known as benchmarking, remains challenging, and it is unclear how it affects quality improvement. This paper piloted and compared two different approaches to benchmarking to assess clinical outcomes in neurorehabilitation. Norming involved comparing routine measures of clinical outcome with external validators. Stacking involved pooling and comparing internal data across several years. The analyses of routine clinical outcome data from 167 patients revealed significant differences in the patient characteristics of those admitted to the same service provider over time, but no differences in outcomes achieved when comparing with historical data or with external reference data. These findings illustrate the potential advantages and limitations of using stacking and norming to benchmark clinical outcomes, and how the results from each approach might be used to evaluate service effectiveness and inform quality improvement within the field of brain injury rehabilitation.

Combined Functional Assessment for Predicting Clinical Outcomes in Stroke Patients After Post-acute Care: A Retrospective Multi-Center Cohort in Central Taiwan

Background and Objective

In 2014, Taiwan’s National Health Insurance administration launched a post-acute care (PAC) program for patients to improve their functions after acute stroke. The present study was aimed to determine PAC assessment parameters, either alone or in combination, for predicting clinical outcomes.

Methods

We retrospectively enrolled stroke adult patients through one PAC network in central Taiwan between January 2014 and December 2020. We collected data on post-stroke patients’ functional ability at baseline and after PAC stay. The comprehensive assessment included the following: Modified Rankin Scale (MRS), Functional Oral Intake Scale (FOIS), Mini-Nutritional Assessment (MNA), Berg Balance Scale (BBS), Fugl-Meyer Assessment (FMA), Mini-Mental State Examination (MMSE), aphasia test, and quality of life. The above items were assessed first at baseline and again at discharge from PAC. Logistic regression was used to determine factors that were associated with PAC length of stay (LOS), 14-day hospital readmission, and 1-year mortality.

Results

A total of 267 adults (mean age 67.2 ± 14.7 years) with completed data were analyzed. MRS, activities of daily living (ADLs), instrumental activities of daily living (IADLs), BBS, and MMSE all had improved between disease onset and PAC discharge. Higher baseline and greater improvement of physical and cognitive functions between initial and final PAC assessments were significantly associated with less readmission, and lower mortality. Furthermore, the improved ADLs, FOIS, MNA, FMA-motor, and MMSE scores were related to LOS during PAC. Using logistic regression, we found that functional improvements ≥5 items [adjusted odds ratio (aOR) = 0.16; 95% confidence interval (CI) = 0.05–0.45] and improved MMSE (aOR = 0.19; 95% CI = 0.05–0.68) were significantly associated with reduced post-PAC mortality or readmission. Whereas, functional improvements ≥7 items, improved FOIS, and MNA significantly prolonged LOS during PAC.

Conclusion

Physical performance parameters of patients with acute stroke improved after PAC. PAC assessment with multiple parameters better predicted clinical outcomes. These parameters could provide information on rehabilitation therapy for acute stroke patients receiving PAC.
