The Impact of Rehabilitation Frequencies in the First Year after Stroke on the Risk of Recurrent Stroke and Mortality

Development and Evaluation of a Mobile Application to Prevent Recurrent Stroke by Enhancing Self-management on Health Outcomes for Stroke Survivors

This study aimed to develop a Mobile Application to Prevent Recurrent Stroke to prevent recurrent stroke by enhancing self-management and to evaluate its effects on stroke survivors' health outcomes. The Mobile Application to Prevent Recurrent Stroke was developed based on social cognitive theory and the model in order of analysis, design, development, implementation, and evaluation process. The Mobile Application to Prevent Recurrent Stroke consisted of health management contents such as information about stroke, its associated risk factors, and required skills to conduct self-management with tailored support and counseling. A quasi-experimental preintervention and postintervention design was used involving a total of 54 stroke survivors. The experimental group (n = 27) was provided the Mobile Application to Prevent Recurrent Stroke for 8 weeks, whereas the control group (n = 27) received an education booklet. The result revealed that medication adherence ( P = .002), healthy eating habit ( P < .001), physical activity ( P < .001), and affected-side grip strength ( P = .002) in the experimental group were significantly better than those in the control group. The systolic blood pressure ( P = .020), diastolic blood pressure ( P < .001), body mass index ( P < .001), and waist circumference ( P < .001) in the experimental group were significantly lower than those in the control group. Stroke survivors can easily use this Mobile Application to Prevent Recurrent Stroke to improve self-management. Nurses can provide tailored care based on the lifelogging data of stroke survivors to prevent recurrent stroke.

Effect of the Frequency of Rehabilitation Treatments on the Long-Term Mortality of Stroke Survivors with Mild-to-Moderate Disabilities under the Korean National Health Insurance Service System

Given the increase in stroke-related social costs, studies on survival and functional prognosis after stroke are urgently needed. Therefore, we investigated the relationship between the frequency of rehabilitation treatments in the acute and subacute phases of stroke and the long-term mortality of stroke survivors with mild-to-moderate disabilities. We performed a retrospective cohort study using data from the Korean National Health Insurance Service database. Our final cohort included 733 patients with national disability registration grades 4-6. The number of special rehabilitation treatment claim codes was used as a proxy for the frequency of rehabilitation treatments. Furthermore, we categorized the rehabilitation frequencies within 24 months of stroke onset as 1-50, 51-200, 201-400, and >400. The dependent variable was all-cause mortality, and it was evaluated from 24 to 84 months after stroke onset. Severe disability was associated with a lower long-term mortality rate in the chronic phase (p < 0.001). In the Cox regression analysis, severe disability, older age, male sex, and chronic kidney disease were independent risk factors for long-term mortality in patients with stroke and mild-to-moderate disabilities. However, the frequency of acute/subacute rehabilitation treatments did not significantly improve long-term mortality. Our results suggest that the association between rehabilitation frequency and lower long-term mortality for patients with mild-to-moderate stroke was inconclusive. Therefore, further study is needed to determine a better-customized rehabilitation treatment system for these patients.

Chronic Phase Survival Rate in Stroke Patients With Severe Functional Limitations According to the Frequency of Rehabilitation Treatment

OBJECTIVE

To investigate the chronic phase survival rate according to the frequency of rehabilitation treatment in the acute and subacute phases in stroke patients with severe functional limitations.

DESIGN

A retrospective longitudinal cohort study.

SETTING

Population-based study using the Korean National Health Insurance Database from 2007 to 2018.

PARTICIPANTS

We enrolled 593 patients who experienced stroke in 2009 with national disability registration (NDR) grade of 3 or less (N=593).

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

The frequencies of rehabilitation treatment within 24 months after stroke were categorized into none, 1-50, 51-200, 201-400, and >400 treatments based on requests made to the Health Insurance Review and Assessment Service. As a dependent variable, we assessed all-cause mortality from 24 to 120 months after stroke.

RESULTS

The study enrolled 283 patients in NDR grade 1 (the most severe), 158 in grade 2, and 152 in grade 3. Groups with more severe functional limitations showed a lower chronic phase survival rate (P<.001). The groups with higher frequencies of rehabilitation treatment in the acute and subacute phases showed a higher chronic phase survival rate (P<.001). In the Cox regression analysis, a higher degree of functional limitation, lower frequency of rehabilitation treatment, older age, male sex, and chronic kidney disease were independent risk factors for chronic phase mortality in stroke patients with severe functional limitations.

CONCLUSIONS

A high frequency of rehabilitation treatment in the acute and subacute phases was associated with the long-term survival of stroke patients with severe functional limitations.

Association between rehabilitation after reperfusion treatment and in-hospital mortality: Results from a national registry study

Background

There is no effective regimen to reduce the mortality of patients treated with intravenous thrombolysis or endovascular therapy (EVT). Therefore, we aimed to examine whether sequential therapy by rehabilitation could effectively reduce the in-hospital mortality of patients treated with reperfusion therapy.

Methods

This prospective registry study included patients with ischemic stroke who were treated by intravenous thrombolysis or endovascular therapy at Stroke Center Work Plan in China between 1 October 2018 and 31 July 2020. The patients were divided into 2 groups: those with (IRT+) or without (IRT–) inpatient rehabilitation therapy (IRT). The primary outcome was all-cause in-hospital mortality. We used Cox proportional hazards models and conducted a propensity score matching analysis to calculate hazard ratios (HRs) for mortality in the thrombolysis-only and EVT groups.

Results

Of the 189,519 patients in the thrombolysis-only group, 35.7% were women, and the median (interquartile range, IQR) age, onset-to-needle time, and follow-up time were 66 (57–74) years, 165 (119–220) min, and 9 (5–12) days, respectively. Among the 45,211 patients in the EVT group, 35.9% were women, and the median (interquartile range, IQR) age, onset-to-puncture time, and follow-up time were 66 (56–74) years, 297 (205–420) min, and 11 (6–16) days, respectively. In the thrombolysis-only group with a median (IQR) initial National Institutes of Health Stroke Scale (NIHSS) score of 6 (3–11), 105,244 patients (55.5%) treated with IRT had significantly lower all-cause in-hospital mortality [0.6 vs. 2.3%; adjusted HR 0.18 (95% confidence interval (CI) 0.16–0.2)] than those without IRT. In the EVT group with a median (IQR) initial NIHSS score of 15 (10–20), 31,098 patients (68.8%) treated with IRT also had significantly lower all-cause in-hospital mortality [2 vs. 12.1%; adjusted HR, 0.13 (95% CI 0.12–0.15)]. IRT remained significantly associated with reduced in-hospital mortality in sensitivity, subgroup, and propensity score matching analyses among both the thrombolysis-only and EVT groups.

Conclusion

Among the patients with ischemic stroke treated with intravenous thrombolysis or endovascular therapy, sequential therapy by rehabilitation was associated with lower all-cause in-hospital mortality. These findings suggest the necessity of promoting inpatient rehabilitation therapy after reperfusion in patients with ischemic stroke.

Ambulation status at an acute care hospital predicts pneumonia and mortality in stroke patients: A retrospective cohort study

AIM

Higher post-stroke functional performance is associated with lower mortality in patients with stroke. This study aimed to investigate the relationship between ambulation ability in the acute phase of stroke, and pneumonia and mortality 1 year after stroke onset.

METHODS

This retrospective cohort study included consecutive stroke patients between April 2008 and December 2018. Patients were divided into six groups according to their Functional Ambulation Category score at discharge (0 [unable to walk] to 5 [able to walk independently]). We observed pneumonia cases and all-cause mortality over 1 year, and investigated the association between Functional Ambulation Category score and pneumonia or mortality. Survival analysis was carried out using Kaplan-Meier curves, log-rank tests and Cox regression models.

RESULTS

We analyzed 1727 consecutive patients (median age 77 years; 54% men). During the observation period, 144 patients (8.3%) experienced pneumonia and 157 (9.1%) died. Increasing ambulatory impairment showed stepwise relationships with the risk of pneumonia and mortality. Compared with patients with a Functional Ambulation Category score of 5, those with scores of 4 and 3 showed no significant association with pneumonia risk; a score ≤2 was significantly different. There was a stepwise relationship between increased gait disturbance and risk of death compared with the Functional Ambulation Category 5 group.

CONCLUSIONS

Ambulation ability at discharge from an acute hospital is an important predictor of pneumonia incidence and survival in stroke patients at 1 year; these associations were observed even after controlling for clinical parameters, such as stroke severity and comorbidity.

Applying Machine Learning to Carotid Sonographic Features for Recurrent Stroke in Patients With Acute Stroke

BACKGROUND

Although carotid sonographic features have been used as predictors of recurrent stroke, few large-scale studies have explored the use of machine learning analysis of carotid sonographic features for the prediction of recurrent stroke.

METHODS

We retrospectively collected electronic medical records of enrolled patients from the data warehouse of China Medical University Hospital, a tertiary medical center in central Taiwan, from January 2012 to November 2018. We included patients who underwent a documented carotid ultrasound within 30 days of experiencing an acute first stroke during the study period. We classified these participants into two groups: those with non-recurrent stroke (those who has not been diagnosed with acute stroke again during the study period) and those with recurrent stoke (those who has been diagnosed with acute stroke during the study period). A total of 1,235 carotid sonographic parameters were analyzed. Data on the patients' demographic characteristics and comorbidities were also collected. Python 3.7 was used as the programming language, and the scikit-learn toolkit was used to complete the derivation and verification of the machine learning methods.

RESULTS

In total, 2,411 patients were enrolled in this study, of whom 1,896 and 515 had non-recurrent and recurrent stroke, respectively. After extraction, 43 features of carotid sonography (36 carotid sonographic parameters and seven transcranial color Doppler sonographic parameter) were analyzed. For predicting recurrent stroke, CatBoost achieved the highest area under the curve (0.844, CIs 95% 0.824-0.868), followed by the Light Gradient Boosting Machine (0.832, CIs 95% 0.813-0.851), random forest (0.819, CIs 95% 0.802-0.846), support-vector machine (0.759, CIs 95% 0.739-0.781), logistic regression (0.781, CIs 95% 0.764-0.800), and decision tree (0.735, CIs 95% 0.717-0.755) models.

CONCLUSION

When using the CatBoost model, the top three features for predicting recurrent stroke were determined to be the use of anticoagulation medications, the use of NSAID medications, and the resistive index of the left subclavian artery. The CatBoost model demonstrated efficiency and achieved optimal performance in the predictive classification of non-recurrent and recurrent stroke.

Functional outcomes among stroke patients in Alagoas, Brazil: observational study

BACKGROUND

Stroke is the principal cause of disability around the world and the ensuing functional dependence (FD) can be correlated with different factors.

OBJECTIVE

To determine how demographic factors and clinical characteristics after stroke distinguish patients who achieve functional independence from those who do not.

DESIGN AND SETTING

Observational study at specialized neurovascular clinic in Alagoas, Brazil.

METHODS

FD was classified according to the modified Rankin scale (mRs): 0 to 2 points were classified as independent (FD-), and 3 to 5 points were classified as dependent (FD+). Logistic regression analysis included age, sedentary lifestyle, the Center for Epidemiological Studies - Depression Scale (CES-D) and the National Institutes of Health Stroke Scale (NIHSS). The Mann-Whitney test and χ2 test were used to compare groups.

RESULTS

We included 190 stroke patients with a mean age of 60.02 ± 14.22 years. We found that 34.8% of the patients were classified as FD+. Lower NIHSS and CES-D scores were more associated with achieving functional independence. Most of the patients had access to physical therapy, and the mean duration of rehabilitation therapy was 65.2 minutes per week. Females had higher prevalence of depressive symptoms (P = 0.005) and rehabilitation time was shorter for hemorrhagic stroke (P = 0.02).

CONCLUSION

We found a FD rate four times greater than in another Brazilian study. Lower stroke severity and fewer depressive symptoms were associated with achieving functional independence. Less than half of the patients were referred to a rehabilitation service at hospital discharge and few had access to multidisciplinary treatment.

Estimating the costs and benefits of stroke rehabilitation in South Africa

OBJECTIVE

This paper explores the economic value of rehabilitation to South Africa, using a costed example of cerebrovascular accident (CVA) (stroke) rehabilitation.

DESIGN

We report an economic modelling approach using a worked cost-effectiveness to validate the argument for the cost-saving benefits of stroke rehabilitation.

SETTING

South African health care, employing analysis of available secondary data from South African research and government reports.

PARTICIPANTS

In line with international trends in stroke epidemiology, we focused on people who were employed prior to having their stroke, with return-to-work as the desired rehabilitation outcome.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE(S)

We used information on stroke rehabilitation and secondary data derived from grey and published literature, to determine if early stroke rehabilitation represents value for money from the government perspective. For our worked example, we used return-to-work rates, intervention costs, and the cost of rehabilitation services to estimate cost-savings as a result of an individualized workplace intervention.

RESULTS

The cost of delivering the individualized intervention was estimated at R5633/patient. Combining survivor rates, return-to-work rate, and costs of the programme, a work intervention programme could result in a net saving of R133.1 million over 5 years (or about R26.6 per year (discount 3%).

CONCLUSION

The value of rehabilitation should not be considered in terms of cost-effectiveness alone, but also as an investment for the country. A staged, prioritized approach should be considered in future South African national health budget.

Health system challenges affecting rehabilitation services in South Africa

BACKGROUND

The World Health Organization (WHO) recommends that access to rehabilitation is a human right. To date, however, rehabilitation in South Africa has not been a health priority. The focus has rather been on saving lives from communicable diseases such as HIV/AIDs and TB, which has been increasingly successful. Whilst more South Africans are now living with pharmacologically managed chronic, communicable diseases, they often suffer significant challenges to their physical and mental health. Moreover, there are many health conditions in South Africa that have not attracted as much attention, and which also compromise individuals' capacity to contribute effectively to their own wellbeing, that of their families and communities, and to the general economy. These include birth trauma, degenerative neurological conditions, acquired injuries such as spinal cord damage, limb amputation or head trauma, and chronic noncommunicable diseases (heart or kidney disease, stroke). In the absence of robust prevalence studies, it is estimated that one-in-three adults suffer from at least one chronic health challenge. For South Africa not to invest in rehabilitation is counter-productive, as it means that a significant percentage of its population cannot contribute to its economy. In the face of scant health resources to underpin equitable rehabilitation services, evidence needs to be provided to demonstrate that for increased expenditure on rehabilitation, there will be increased return at individual, family, society, and country levels.

PURPOSE

This article presents challenges and solutions to ensure that South Africa can meet WHO 2030 Rehabilitation Goals for equitable provision of effective public rehabilitation services using the WHO's health system building block framework.IMPLICATIONS FOR REHABILITATIONTo meet the challenge of providing rehabilitation for those in need requires country-specific, strategic, evidence-informed, and planned decisions in terms of best investment for highest return.Whilst there is sound international evidence for best-practice rehabilitation care, country-specific strategies are required to identify and address local barriers to evidence implementation.In South Africa, where rehabilitation has not been a priority to date, it is important that a planned and well-costed approach is taken to ensure provision of equitable, accessible, affordable, and evidence-based rehabilitation.Measuring social, economic, and educational return on investment from rehabilitation should be part of the South African service-delivery planning process.National data could be obtained through adding additional questions on disability to the national census and through local surveys and reports at various public health care facilities.

Impact of Functional Status on Noncardioembolic Ischemic Stroke Recurrence Within 1 Year: The Korean Stroke Cohort for Functioning and Rehabilitation Study

Background and Purpose

Few studies have investigated the relationship between the specific functional factors potentially associated with functional level and stroke recurrence. We conducted a study of patients with noncardioembolic ischemic stroke (NCIS) to determine the functional factors affecting recurrence within the first year.

Methods

In total, 568 first-ever NCIS patients (age=65.1±17.4 years, mean±SD) were analyzed in a multicenter, prospective cohort study registered from August 2012. Demographic characteristics, past medical history, comorbidities, laboratory data, stroke features in neuroimaging, acute treatments, and medications at discharge were assessed. Functional factors reflecting gross functional impairment, ambulatory function, motor function, activities of daily living, cognition, language ability, swallowing function, mood, and quality of life were comprehensively evaluated in face-to-face assessments using standardized tools at the time of discharge.

Results

The cumulative incidence of stroke recurrence in NCIS was 6.0% (n=34) at 1 year. The period from admission to discharge was 34.4±7.0 days. The independent predictors of stroke recurrence within 1 year in multivariate Cox proportional-hazards regression analyses were 1) age [per-year hazard ratio (HR)=1.04, 95% confidence interval (CI)=0.97–1.06, p=0.048], 2) Charlson Comorbidity Index higher than 2 (HR=1.72, 95% CI=1.26–2.22, p=0.016), 3) modified Rankin Scale score of 3 or more at discharge (HR=1.56, 95% CI=1.22–1.94, p=0.032), and 4) Functional Ambulation Category of 3 or less at discharge (HR=2.56, 95% CI=1.84–3.31, p=0.008).

Conclusions

In addition to patient age, moderate-to-severe functional impairment requiring the help of others (especially for ambulation) at the time of discharge and the severity of comorbidity were independent predictors of stroke recurrence within 1 year of the first NCIS.

National trends in stroke and TIA care in U.S. emergency departments and inpatient hospitalizations (2006-2014)

BACKGROUND

We examine recent trends in U.S. emergency department (ED) and hospital care for stroke and transient ischemic attack (TIA).

METHOD

We used national ED and inpatient data from the Healthcare Cost and Utilization Project 2006-14. We explored trends in care and outcomes for patients treated in U.S. hospitals with stroke and TIA using descriptive statistics, as well as intracranial hemorrhage (ICH), a complication of stroke treatment.

RESULTS

From 2006 to 14, there were 3.9 million U.S. ED visits with stroke and 2.5 million with TIA. Over the study, stroke visits grew 25% while TIA decreased 2%. Both conditions were more common among women and older adults, and most had Medicare insurance; however, Medicaid increased from 5.8% to 9.6% for stroke and 4.3% to 7.5% for TIA. Full inpatient hospitalizations fell for stroke from 89% to 83%, and TIA from 61% to 47%. Transfers from the ED for stroke & TIA increased from 4% to 8% and 2% to 5%, respectively. Inpatient mortality decreased for stroke & ICH and costs increased for all three conditions; however, length of stay (LOS) did not significantly change.

CONCLUSION

Over this nine-year study period, the average age of stroke & TIA patients was unchanged in U.S. hospitals; however, the proportion with Medicaid insurance increased considerably. Stroke incidence increased while TIA decreased slightly. Full inpatient hospitalizations are declining for both conditions, while transfers are on the rise. Average inpatient costs increased dramatically for all three conditions while mortality for stroke & ICH fell significantly.

A clinical study on acupuncture in combination with routine rehabilitation therapy for early pain recovery of post-stroke shoulder-hand syndrome

The clinical effect of acupuncture in combination with rehabilitation therapy for post-stroke shoulder-hand syndrome (SHS) was explored. Patients (178) with post-stroke SHS who received treatment in the Dalian Second Hospital from March 2012 to March 2016 were included in this study. The patients were divided into experimental group (89 cases) and control group (89 cases). Patients in the control group received rehabilitation therapy, while those in the treatment group received acupuncture treatment in addition to rehabilitation therapy. Visual analogue scale (VAS) was applied to assess the pain degree of patients. Fugl-Meyer assessment (FMA), functional comprehensive assessment (FCA) and assessment of quality of life (QoL) were used to evaluate rehabilitation condition of the patients. Early pain relief, rehabilitation of upper extremity motor function and improvement of QoL after treatment were compared between the two groups. The scores of VAS, FMA, FCA and QoL showed obvious differences between the two groups after treatment (P<0.05). The scores of the experimental group were significantly better than those of the control group, and the improvement in upper extremity motor function of the patients in the experimental group was better than that of the patients in the control group. The total effective rate of the patients in the experimental group was higher than that of control group (P<0.05). The effect in improving the upper extremity motor function of the patients in the experimental group was better than that of control group. The scores of QoL of the patients in the experimental group were better than that of the patients in the control group (P<0.05). In conclusion, acupuncture in combination with rehabilitation therapy can improve early pain and rehabilitation significantly and enhance QoL for patients with post-stroke SHS, which is worthy of being widely used in clinical practice.
