Abstract
Objective
To evaluate the relationship between caregiver nature and availability, and rehabilitation
outcomes in subacute stroke.
Design
Retrospective cohort study.
Setting
Four community rehabilitation hospitals.
Participants
Patients with subacute, first-time stroke (N=4042; 48.5% men; mean age ± SD, 70.12±10.4y;
51.5% women; mean age ± SD, 72.54 ±10.0y).
Interventions
Not applicable.
Main Outcome Measures
Rehabilitation effectiveness, defined as the percentage of potential improvement eventually
achieved with rehabilitation; and rehabilitation efficiency, defined as the rate of
functional improvement during rehabilitation.
Results
In our cohort, 96.7% had available caregiver(s), of which 42.0% were primarily supported
by foreign domestic workers (FDWs), 25.9% by spouses, 19.3% by first-degree relatives,
7.8% by other relatives, and 5.1% by other caregivers. Using quantile regression,
we found that having a caregiver was independently associated with rehabilitation
efficiency (β=−3.83; 95% confidence interval [CI], −6.99 to −0.66; P=.018). The relationship between caregiver availability and rehabilitation effectiveness
was modified by patient sex in that the negative association was significantly greater
in men (β=−22.81; 95% CI, −32.70 to −12.94; P<.001) than women (β=−5.64; 95% CI, −14.72 to 3.44; P=.223). Having a FDW as a caregiver compared with a spousal caregiver was negatively
associated with rehabilitation effectiveness (β=−3.95; 95% CI, −6.94 to −0.95; P=.01) and rehabilitation efficiency (β=−1.83; 95% CI, −3.14 to −0.53; P=.006). The number of potential caregivers was only significantly associated with
rehabilitation effectiveness at the bivariate level (P=.006).
Conclusions
Caregiver identity, and possibly availability, appears to negatively affect rehabilitation
outcomes in subacute stroke. A better understanding of these relationships has potential
implications on clinical practice and policy directions.
