Abstract
Background. This meta-analysis aims to assess the outcomes of supported intervention transitional care compared to traditional care for stroke survivors.
Materials and methods. A systematic literature review was accomplished and 4,437 stroke patients were recruited for the current study; 2,211 of them were treated with transitional care and 2,226 with traditional care. The inclusion criteria of the current study recruited only randomized clinical trials up until November 2023. A random analysis model was used to analyze the continuous and dichotomous models.
Results. Supported intervention transitional care (early supported discharge) for stroke survivors showed a significant (p = 0.002) impact regarding the functional status of patients as expressed by the Barthel index (mean difference (MD) = 0.57, 95% confidence interval (95% CI): 0.20–0.94, I² = 93.72%). On the other hand, there were no considerable (p > 0.05) differences regarding other outcomes such as activities of daily living, the Caregiver Strain Index (CSI), the modified Rankin scale (mRS), and mortality (MD = 0.29, 95% CI: –0.12–0.69, I² = 94.5%; MD = –0.13, 95% CI: –0.40–0.14, I² = 68.65%; MD = –0.13, 95% CI: –0.49–0.23, I² = 83.33%; and MD = –0.19, 95% CI: –0.58–0.17, I² = 0%; respectively).
Conclusions. Supported transitional care allowed stroke survivors to succeed in enhancing their functional status outcomes compared with controls, while there was no significant impact regarding mortality rate. Further investigations and multicenter studies are required to enhance the evidence.

Background
Individuals undergoing recovery after an acute stroke face considerable difficulties in independently managing the transition from hospital to home. The need for these interventions is due to the need to adapt to a change in one’s health condition, a new diagnosis and the recognition of ongoing care requirements.1 Upon discharge from the hospital, numerous stroke survivors require comprehensive and continuous rehabilitation and assistance to regain and develop skills and capacities, adjust to the limits resulting from the stroke, and address their emotional, social and practical needs both in the community and at home. Interventions to achieve these goals, like early supported discharge (ESD), provided to the stroke survivor during the transition to home from the hospital, decrease the duration of hospitalization in addition to reducing the healthcare costs of stroke care.2
The transition of care as an expression is intricate, difficult to define, and is frequently used in several studies and guidance interchangeably with other concepts such as care navigation, care coordination and care continuity. Transitional care includes both the medical component of transferring care and the needs of the stroke patient and their carer.3 The expression “transition of care” can be defined as a series of measures aimed at ensuring the coordination and continuousness of healthcare when patients move from one site to another or to different levels of care. Rehabilitation interventions during care transitions are recognized as crucial for coordinating care and have an impact on the quality of care and the occurrence of hazardous episodes.4, 5
Stroke survivors can be offered support interventions, such as educational programs and personalized discharge plans, as they move from organized stroke care to their homes. These interventions seek to promote the consistency and excellence of healthcare, improve functional results, decrease healthcare expenses, and enhance the overall user experience.6 Nevertheless, there is a dearth of understanding regarding effective support treatments to optimally handle transitions for this intricate health condition.
Assessment of the impact of transitional care can be evaluated using different parameters such as the Barthel index, activities of daily living, the Caregiver Strain Index (CSI), the modified Rankin scale (mRS), and mortality rate. The objective of these parameters is to assess the patient’s ability to perform daily activities and the necessity of nursing care.
The national stroke recommendations of Canada,7 USA8 and Scotland9 utilize ESD as a rehabilitation technique for post-acute care. Early supported discharge is a crucial element of the stroke care system in the UK. The manuals clearly identify the target group, aim, scope, and methodology of ESD.10, 11
Objectives
The purpose of this study was to evaluate the effects of transitional care with supported intervention in comparison to traditional care when it is applied to stroke survivors in terms of functional status, physical activity and mortality.
Materials and methods
Study design
The epidemiological declaration12 was the subject of the present meta-analysis, which encompassed studies that tracked a prearranged study technique.13 Data gathering and analysis of recruited studies were conducted using several scientific databases in accordance with the specified inclusion criteria. The study inclusion sequence is illustrated in Figure 1.
Eligibility and inclusion
This study was conducted to assess the impact of assisted intervention transitional care compared to traditional care in individuals who have experienced a stroke. The sensitivity study exclusively encompassed publications that examined the impact of interventions on mortality rate, functional status, validity of daily activity, and the CSI score. To conduct subclass and sensitivity analyses, several patient types were compared to the medical intervention groups.
Inclusion criteria
1. The acceptable study design included in the current study is randomized clinical trials published before November 2023.
2. The study included patients who experienced a stroke (stroke survivors) and are receiving post-stroke care.
3. The design of the study method must be a comparison, comparing outcomes of 2 different interventions (supported transitional care compared to traditional care).
Exclusion criteria
1. Articles that did not present results of the comparison between different interventions in an acceptable form, such as interquartile ranges (IQRs) or medians. The results of different outcomes should be expressed in the form of a mean (± standard deviation (±SD)) or event/total.
2. Studies in the form of letters, review articles, books, or book chapters.
Identification
We carried out a search concerning papers published up until November 2023 using a combination of several keywords and comparable words for transitional care, rehabilitation, stroke, stroke survivors, supported early discharge, functional status, Barthel index, CSI, and supported nursing intervention.14 A protocol of our search strategies was defined in accordance with the PICOS principle as follows: P (population) – stroke survivors, I (intervention/exposure) – ESD care (supported transitional care), C (comparison) – transitional care compared to traditional care, O (outcome) – Barthel index, mortality, CSI, mRS, and activity of daily living, and S (study design) – randomized clinical studies (RCTs).
The authors performed a thorough search of the PubMed, Cochrane Library, Embase, Ovid, and Google Scholar databases until November 2023 using the keywords and related terms. Any article that did not discuss and evaluate the role of ESD compared to traditional care was disregarded after an evaluation of the titles and abstracts of the articles that had been collected into a reference managing program. Two authors served as reviewers to find pertinent studies.
Screening
The data were filtered based on specific criteria, including the first author’s surname, publication year, country of study, study design, recruited population type, study duration, demographic information, clinical and treatment characteristics, total number of participants, standardized presentation of study-related features, information source, and outcome. Each study was assessed for potential bias, and the methodological quality of the chosen publications was analyzed independently by 2 authors in a blinded manner.
The presence of bias in each of the included studies was assessed using Review Manager v. 5.3 software (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark), and the findings were categorized into 3 levels: low, moderate or high potential for bias. Two of the authors conducted a methodological evaluation of each study.
Statistical analyses
The mean difference (MD) with a 95% confidence interval (95% CI) was calculated using random dichotomous (mortality rate) and continuous models (Barthel index, activities of daily living, mRS, and CSI).15 All p-values were calculated using 2-tailed tests. We used a random model based on the high level of differences between the included studies and the absence of high similarity regarding study parameters between all studies included for analysis of the model. The selection of the analysis model was determined after an accurate assessment of all included studies and comparisons of these papers to each other. According to the data, a random-effects model was fitted. Using a constrained maximum-likelihood estimator, the level of heterogeneity (Tau2) was calculated. The I2 index, which is a numerical number ranging from 0 to 100, was obtained using Jamovi software (https://www.jamovi.org). The heterogeneity level was shown with percentages ranging from 0% to 100%, and it was also expressed with percentages indicating low, moderate and high levels of heterogeneity. Begg’s and Egger’s tests were used to conduct quantitative research on publication bias, and the presence of publication bias was deemed to be present if the p-value was >0.05.
Results
After reviewing 15,889 pertinent studies, 22 research papers meeting the inclusion criteria from the period of 1997 to 2022 were included in the meta-analysis.16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37 The results of these investigations are compiled in Table 1 (characteristics of included research including year, country, subject count, and study design).
Barthel index
A total of 13 studies were included in the analysis of the impact of intervention (transitional care) compared to control (traditional care) for stroke survivors. The analysis of this model showed a significantly (p = 0.002) higher impact of transitional care on functional status outcomes compared to the controls (MD = 0.57, 95% CI: 0.20–0.94, I² = 93.72%). Both the Begg’s and Egger’s tests did not show significant evidence of publication bias, with p-values of 0.1289 and 0.1602, respectively (Figure 2A). Subgroup analysis of these models consisted of 2 subgroups, 1st evaluating the impact of the interventions for up to 3 months (7 studies) and a 2nd subgroup evaluating the impact of the interventions for up to 6 months. A total of 7 studies comparing the impact of transitional care intervention with a control for up to 90 days after stroke survival were included in the analysis. The finding of this analysis showed a significant difference (p = 0.001) between the intervention and control groups, reflecting a higher impact of transitional care (MD = 0.90, 95% CI: 0.35–1.46, I² = 92.4%). Both the Begg’s and Egger’s tests did not show significant evidence of publication bias, with p-values of 0.56 and 0.52, respectively. (Figure 2B). On the other hand, 6 studies were analyzed to evaluate the effects over a longer period (6 months). Findings of this model, in contrast with previous models, showed a nonsignificant (p = 0.26) impact between the intervention and control (MD = 0.14, 95% CI: –0.11–0.39, I² = 94.6%) (Figure 2C). The Egger’s test revealed the presence of funnel plot asymmetry (p = 0.045), whereas the Begg’s test did not show any significant results (p = 0.27).
Activities of daily living
A total of 11 studies were included in the analysis of the impact of the intervention compared to controls on activities of daily living (ADL) for stroke survivors. The analysis of this model showed a nonsignificant (p = 0.16) impact of transitional care compared to controls (MD = 0.29, 95% CI: –0.12–0.69, I² = 94.5%) (Figure 3). The Begg’s test revealed significant funnel plot asymmetry (p = 0.026), whereas the Egger’s test did not provide significant results (p = 0.053).
Modified Rankin scale
A total of 4 studies were included in the analysis of the impact of intervention compared to control on the mRS for stroke survivors. The analysis of this model showed a nonsignificant (p = 0.47) impact of transitional care compared to controls (MD = –0.13, 95% CI: –0.49–0.23, I² = 83.33%) (Figure 4). Both the Begg’s and Egger’s tests did not show significant evidence of publication bias (p = 0.33 and p = 0.11, respectively).
Caregiver Strain Index
A total of 5 studies were included in the analysis of the impact of the intervention compared to controls on the CSI for stroke survivors. The analysis of this model showed a nonsignificant (p = 0.33) impact of transitional care compared to controls (MD = –0.13, 95% CI: –0.40–0.14, I² = 68.65%) (Figure 5). Both the Begg’s and Egger’s tests showed no significant evidence of publication bias (p = 0.82 and p = 0.60, respectively).
Mortality
A total of 8 studies were included in the analysis of the impact of the intervention compared to controls on the mortality rate of stroke survivors. The analysis of this model showed a nonsignificant (p = 0.30) impact of transitional care compared to control (MD = –0.19, 95% CI: –0.58–0.17, I² = 0% (Figure 6). Both the Begg’s and Egger’s tests did not show significant evidence of publication bias (p = 0.27 and p = 0.47, respectively).
However, the Begg’s and Egger’s tests determine publication bias statistically, but also visual evaluation of funnel plot symmetry provides supporting evidence. The funnel plots for 6 models showed a different degree of asymmetry (Supplementary Fig. 1), reflecting the presence of publication bias, while the funnel plot for the mortality rate model showed a higher degree of plot symmetry (Supplementary Fig. 2).
Discussion
Twenty-two randomized clinical trials published between 1997 to 2022 were included in the meta-analysis as they met the inclusion criteria.16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37 Interventions evaluated using the Barthel index, displaying a mean value of 0.57 and a 95% CI ranging from 0.20 to 0.94, demonstrated that transitional care, also known as ESD, had a substantial influence (p = 0.002) on the functional state of stroke survivors. However, it is worth mentioning that there were no noteworthy differences (p < 0.05) in relation to the other outcomes, including activities of daily living, mRS, CSI, and death.
Although there have been advancements in acute stroke care on a global scale, deficiences are still observed in the process of reintegrating stroke patients into their communities and in their ability to manage their own care following a stroke.6 Our research indicates that interventions involving multiple components improve short-term functionality. Nevertheless, these interventions seem to have a diminished effect on functional status 6 months following the transition phase. Research indicates that it is challenging to maintain the results attained by self-management tactics. However, it has been found that increased self-efficacy plays a crucial role in the successful and long-lasting benefits of self-management programs.38 This suggests that self-efficacy should be a deliberate goal of self-management programs. There is a need for a deeper comprehension of the tactics that promote long-term self-confidence. Contemporary research explains that healthcare practitioners and healthcare systems must go beyond traditional self-management strategies and customize self-management support to suit the unique needs of each individual, taking into account their life circumstances and the progression of their condition.39
There are several scales to evaluate stroke and other critical care survivors, such as the Barthel index.40 It gauges a person’s ability to move around and operate independently in daily living tasks, including eating, washing, grooming, dressing, using the restroom, chair transfer, ambulating, and climbing stairs. The scale lists 10 tasks and assigns a grade based on how much time or help the patient needs. The total score ranges from 0 to 100, where lower numbers denote a higher degree of nursing need.41
A previous study conducted by Langhorne et al. resembled our study.2 They carried out a systematic literature review and meta-analysis of 17 randomized controlled trials that involved a total of 2,422 patients. The study found that ESD shortened the duration of hospitalization by approx. 6 days and decreased long-term reliance on assistance for daily activities. Our investigation observed a limited number of instances where ESD resulted in notable disparities in the results. This can be linked to the uniform nature of therapies, which do not include patient-led, family-led or telerehabilitation methods. In contrast, Cochrane’s study intentionally included a wide range of criteria for intervention. These disparities resulted in the deletion of several research studies, potentially leading to a decrease in the number of situations where ESD had a significant positive impact on the study results.2 Langhorne et al. discovered that the implementation of an ESD program, which includes a multidisciplinary team of specialists, led to reduced long-term functional dependency and readmission rates in stroke patients. Furthermore, the duration of hospitalization was significantly shortened in comparison to the previous service.2 Specifically, the overall mean duration of hospitalization decreased to 6 days, and the occurrence of adverse outcomes, such as mortality or readmission, decreased by around 5%. Previous studies did not find any significant variations in the reported outcomes. However, the cost of the ESD program was 15–23% lower compared to traditional treatment.10
In a comprehensive review of the extant literature on transitional management in Germany, Hempler et al. employed a systematic approach to identify and analyze the current research on this topic.42 The literature analysis included a total of 18 studies. However, all of these studies lacked sufficient quality regarding standardized transition management systems. The study findings suggested that Germany requires standardized discharge management services, such as ESD programs. However, countries other than Germany are making efforts to offer alternative services, and these services are gradually being implemented in Asian countries, as reflected by the growing demand for such services in, e.g., South Korea. In contrast to the review study conducted in Germany,42 our work holds significance as it involved 2 researchers who independently chose and assessed the papers for meta-analysis.
Limitations
There are a few limitations that apply to this review. In the first place, the quality of the trials, which are fraught with a high risk of bias, inconsistency and imprecision, limits the certainty of the findings. Additionally, there were not many studies that reported on outcomes such as cognition and exhaustion, both of which have the potential to significantly impact functional performance and are essential to stroke survivors. A considerable number of research studies on transitional care did not incorporate outcomes for caregivers, which can influence the utilization of resources and the costs incurred by the healthcare system. Furthermore, there was a limited amount of reporting of adverse occurrences.
Conclusions
The provision of supported transitional care to stroke survivors was found to be effective in enhancing functional status outcomes when compared with a control group. However, there was no discernible impact on mortality rates. To strengthen the evidence, additional research and studies involving multiple centers are required.
