Effectiveness of dyadic interventions to improve stroke patient-caregiver dyads' outcomes after discharge: A systematic review and meta-analysis study

Abstract

Background

Because of the importance of a dyadic approach, it is necessary to conduct a systematic review to identify which dyadic intervention could be implemented for stroke survivor-caregiver dyads after discharge from the rehabilitation hospital to improve outcomes.

Aims

The aims were to systematically review the evidence to identify which dyadic interventions have been implemented in stroke survivor-caregiver dyads to improve stroke survivor-caregiver dyads' outcomes and to analyse, through a meta-analysis, which intervention was found to be the most effective.

Methods

A systematic review and meta-analysis were conducted using the following electronic databases: PubMed, CINAHL and PsycInfo. Randomized controlled trials (RCTs) and quasi-RCT studies published within the last 10 years were included. Quantitative data were extracted from papers included in the review using the standardized data extraction tool from JBI-MAStARI. Pooled effects were analysed between the experimental and control groups for each outcome.

Results

Sixteen studies involving 2997 stroke survivors (male gender=58%) and 2187 caregivers (male gender=25%) were included in this review. In 16 studies, which were subdivided into three quasi-RCTs and 13 RCTs, the application of dyadic interventions for stroke survivors and caregivers was systematically reviewed, but only a few of these identified a significant improvement in the stroke survivors' and caregivers' outcomes of its intervention group. Dyadic interventions showed a significant effect on stroke survivors' physical functioning (p=0.05), memory (p<0.01) and quality of life (p=0.01) and on caregivers' depression (p=0.05).

Conclusions

This study provides moderate support for the use of a dyadic intervention to improve stroke survivors' physical functioning, memory and quality of life and caregiver depression.
