Stroke rehabilitation use and caregiver psychosocial health profiles in Singapore: A latent profile transition analysis

Abstract

Objectives: To identify and describe the transition of latent profiles characterized by caregiver psychosocial health characteristics over a 12-month period, to determine if stroke rehabilitation use at 12-month post-stroke differed by profile transition patterns, and to investigate if the identified profiles at 3-month post-stroke influence the explanation of stroke rehabilitation use at 12-month post-stroke by stroke rehabilitation use at 3-month post-stroke, with covariates.Design: Latent profile transition analysis of caregiver psychosocial health with stroke rehabilitation use at 12-month post-stroke as outcome. Setting and Participants: 149 stroke patient-caregiver dyads from the Singapore Stroke Study.Methods: Cross-sectional latent profile analyses were conducted on caregiver psychosocial health indicators of burden, depression, health status, quality of relationship with patient, and social support. Changes in latent profile classification over three time points (baseline, 3-month, and 12-month post-stroke) were analysed using latent transition analysis. A transition model with stroke rehabilitation use at 12-month post-stroke as the outcome was tested after accounting for covariates.Results: Two distinct caregiver psychosocial health latent profiles were found across time: non-distressed and distressed. Most caregivers were classified as non-distressed and remained non-distressed over time. Distressed caregivers at baseline were 76% likely to become non-distressed at 12-month post-stroke. Regardless of profile transition patterns, non-distressed caregivers at 12-month post-stroke tended to have cared for stroke rehabilitation non-users at 12-month post-stroke. Patient depression explained profile classification at 3-month and 12-month post-stroke. After accounting for covariates, the association between stroke rehabilitation use at 3-month and 12-month post-stroke was present only when caregivers were non-distressed at 3-month post-stroke.Conclusions and Implications: With covariates, stroke rehabilitation use at 3-month positively predicted rehabilitation use at 12-month post-stroke only when caregivers were non-distressed at 3-month post-stroke. Early psychosocial health assessment and sustained support should be made available to stroke caregivers to enhance their well-being and subsequent patient rehabilitation participation.

Informal caregiving in Singapore: macroeconomic realities and measures

“…18,19 Recent research found that Singapore caregivers of stroke survivors who were distressed at hospital discharge had a 24% likelihood of remaining distressed 12 months after discharge. 20,21 The proposed national study should include a time dimension, and ask if caregiver well-being fluctuates similarly when the care recipient suffers from other chronic conditions or disabilities, and if this trend persists over a longer time horizon.…”

Prevalence and risk factors of ischemic stroke-related headache in China: a systematic review and meta-analysis

“…Globally, stroke is the second leading cause of death [1] and poses a serious burden to the caregivers and society [2,3]. Ischemic stroke accounts for more than 70% of strokes [4].…”
