Educating Caregivers to Reduce Complications and Improve Outcomes of Stroke Patients (ECCOS) - A Cluster-Randomized...

Stroke constitutes a significant public health problem in developing countries. Caregivers provide an important support system for patient care but usually lack knowledge and skill to attend their stroke patients. We assessed whether a caregiver-directed educational intervention would reduce hospital-acquired complications and improve stroke patients' outcomes.

We randomly assigned two Neurology inpatient wards to receive either standard care or an educational intervention. The coprimary outcomes included incidence of hospital-acquired complications and in-hospital mortality. Secondary outcomes included the modified Rankin Scale and mortality at three months.

Among 164 patients recruited, 82 received intervention, and standard care each. The mean (Standard deviation) Glasgow coma scale of patients was 11.01 (3.4), and National Institute of Health Stroke Scale was 19.17 (8.54). The incidence of complications (72 in the intervention versus 81 in the control group; p=0.56) was not different. Ten patients (12.2%) in the intervention group and 16 (19.5%) in the control group (p=0.20) died in-hospital. Twenty patients (27.8%) in the intervention and twelve (18.2%) in the control group attained modified Rankin Scale 0-2 at three months (p=0.12). The mortality at three months (20 [24.4%] in the intervention versus 25 [30.5%] in the control group) was not different (p=0.38). The intervention group had fewer complications (42 versus 68 in the control group; p=0.01) during the initial ten days of hospital stay, but adjusted analysis revealed no difference.

A structured educational intervention did not reduce the incidence of hospital-acquired complications, mortality, or morbidity. However, there was a trend towards fewer complications in the initial days of hospital stay. Extended hospital stay, caregiver fatigue, and dilution of the intervention over time might be reasons for the apparent lack of effect. CLINICAL TRIAL REGISTRATION-URL: http://www.ctri.nic.in.
