Clinical Trial Summary
This is an interdisciplinary, intervention study with stroke survivors and their spousal
caregivers after discharge from a rehabilitation unit. It will determine whether couples
receiving home visits from nurses and therapists over a 6 month period demonstrate better
function and less psychological distress than couples who receive information by mail. All
couples are visited every 3 months by a nurse who assesses their physical and psychosocial
functioning.
Description:
This 5-year randomized intervention study uses an advanced practice nurse, with the
assistance of an interdisciplinary rehabilitation team, to provide education, support, skill
training, counseling, and social and community linkages to stroke survivors and their spouses
for 6 months post-hospital discharge. The intervention will be delivered using previously
tested protocol guidelines. Stroke survivors and their spousal caregivers will be assessed to
determine whether or not the intervention is successful in (1) improving function, quality of
life and perceived health and decreasing depression in the stroke survivor; (2) decreasing
unplanned clinic and emergency room visits, reducing rehospitalizations and admissions to
nursing homes; (3) decreasing depression, burden, stress and improving the health of spousal
caregivers and (4) decreasing cytokine imbalances related to the chronic stress of caregiving
among spouses. Assessments will be made at baseline and at 3, 6, 9, and 12 months
post-discharge on the stroke survivor and on the spousal caregiver by a nurse who is masked
to the group assignment. To determine the effect of the intervention on cytokine imbalance,
the researchers will: (1) generate cytokines from cell cultures (mitogen-induced and antigen
specific T-cell lines) and (2) analyze culture supernatants and plasma samples for their
immunoregulatory cytokine content. The laboratory technician and immunologist will be masked
to the intervention group. All covariates (i.e., sociodemographic characteristics, severity
of the stroke, dyadic relationships, family functioning, co-morbid health conditions, etc.)
will be evaluated to determine which are significantly related to the outcomes and only those
will be included in the model. Hierarchical Linear Models (HLM) will be used to model change
over time for individual participants using a polynomial form. Depending on the nature of the
change function, individual parameter estimates of the intercept, slope, and if necessary,
curvature will be compared across groups.
