Explore the risk perception and evaluate the effectiveness of competency-based intervention (CBI) on knowledge and lifestyle changes among type 2 diabetes mellitus patients

OBJECTIVE: This is a study to explore the risk perception among T2DM patients and to compare the pre-test and post-test levels of knowledge and lifestyle changes among T2DM patients at selected hospitals in Chennai. Most diabetics have type 2 diabetes, accounting for 85-90% of cases. Diabetes is a worldwide epidemic disease with distressing human, societal, and economic effects. It affects an estimated 382 million people worldwide in 2021.

PATIENTS AND METHODS: The research design used mixed-method research, such as Exploratory Sequential Design. The phenomenological approach, in that sequential exploratory design for the qualitative and true experimental design for the quantitative study, was chosen. 60 samples of T2DM patients were selected using a simple random sampling technique through the lottery method and divided into experimental and control groups for every 30 samples in quantitative. Five samples were selected using convenient sampling for qualitative.

RESULTS: In the quantitative study, the pre-test showed 4 (13.3%), and 5 (16.7%) adequate knowledge and lifestyle changes in both groups. Post-test experimental group showed that 23 (76.7%) had adequate knowledge and 23 (76.7%) changes in lifestyle found a drastic transformation from the pre-test as well as in the control group. The calculated Chi-square value showed a significant difference in the post-test level of lifestyle change among the T2DM patients between the groups at p<0.001 level.

CONCLUSIONS: This inferred that Competent Based Intervention (CBI) on knowledge and lifestyle changes administered to T2DM patients in the experimental group was found to be effective. Competent Based Intervention is a nursing intervention that is well accepted and adopted by patients and easily implemented by nurses. It can be included in the nursing curriculum. In-service education can be arranged once a month for staff nurses and faculty members regarding Competent Based Intervention. The Nurse educator should encourage the nurses to effectively utilize research evidence-based practice related to Competent Based Intervention for patients with type 2 diabetes mellitus.
