Reduction of Recurrence of Stroke by Nurse-led Education in Bangladesh

Overview

Stroke is a major public issue that can be occurred a patient with severe and unbearable disability for a long time. Recurrence of stroke is increasing due to a lack of knowledge and compliance with treatment regarding the modifiable risk factors of stroke and behavioral and lifestyle changes. Nurse-led health education with (self) monitoring of modifiable risk factors and behaviors can be an effective way to create knowledge about the behavioral changes in stroke patients. The investigators hypothesized that health education among first stroke patients and their family caregivers could reduce the stroke recurrence rate by controlling modifiable risk factors compared to the first stroke patients without health education.

In Bangladesh, the top cause of death per 100,000 population for both sexes aged all ages in 2019 is stroke. About 79.9 percent of the total patients were suffering from ischemic stroke, and 15.7 percent and 4.6 percent were diagnosed with hemorrhagic and subarachnoid hemorrhage respectively. One study found the cumulative recurrence rate was 14.7% at three months, 15.3% at six months, 17.3% at the ninth month, and 20% at one year (n=150). This study aims to evaluate the effect of health education among first-stroke patients and their family caregivers for reducing the recurrence of stroke. The investigators also assess the number and rate of all adverse events, changes in values of modifiable risk factors, and change scores in knowledge, lifestyle behavior, medication adherence, and QoL. In this study, participants were the first stroke patients who were discharged from the National Institute of Neurosciences \& Hospital (NINSH) and the family caregivers of the patients. Written informed consent is received from the patient when the patient is the main person of self-management of recurrence prevention, if the patient cannot give consent by disability, his/her family caregiver provided consent. At baseline, blood specimens such as blood total cholesterol, HDL-cholesterol, HbA1c, and diagnosis including adverse events and blood pressure measurement data were obtained from the hospital records/patient's chart. At first, the research assistant (RA) nurse should confirm the written consent form for the participants. Then, the RA nurse took the baseline data through the interview. The raw data is stored and locked in secured places in NINSH. Confidentiality of data is of utmost importance; therefore, every effort is made to safeguard the identity of participants and protect subject privacy. All hard copies of data are stored under lock and kept in the NINSH. The sample size was based on the calculation of a 10% reduction in recurrence rate compared with the control group with a statistical power of 80% at α= 0.05 (2-tailed). Considering the dropout rate of 10%, the final sample size is 432 (2 arms). To compare the outcomes of the Intervention Group and Control Group, an intention-to-treat (ITT) analysis and a full analysis set (FAN) were conducted. Descriptive analysis was done to assess the baseline data. For categorical data, the chi-square (X2) test, and for continuous variables, the t-test, or Mann-Whitney U test was employed to compare the two groups where appropriate. For secondary endpoints, after adjusting for confounding variables such as age, an analysis of covariance (ANCOVA) was used to assess the effect of the intervention on the outcomes. To compensate for missing data, the last observation carried forward was measured. The significance level will be set at P=0.05. Data will be analyzed using SPSS (version 26.0; IBM Corp). In 5% of the study participants, the quality control team independently checked the collected data on the same day using a field-tested methodology. Detected errors were corrected immediately at the field site. The findings of the quality control team are considered for necessary corrections if any major discrepancies are found.
