Effectiveness of Health Literacy Program for Polypharmacy Patients (HLP-CKD)

Background: Patients with polypharmacy are at a higher risk of drug-induced kidney injury. Enhancing health literacy is a key strategy to empower these patients to engage in protective health behaviors.

Objectives: 1) To compare health literacy scores before and after participating in the program. 2) To compare CKD prevention behaviors between the experimental and control groups.

Methodology: This is a quasi-experimental study with a pre-test/post-test design.

Experimental Group: Receives the "Health Literacy Promotion Program," which includes educational sessions, skill-building for medication management, and follow-up support.

Control Group: Receives routine nursing care and standard health education. Intervention Details: The program focuses on 6 aspects of health literacy: access, understanding, communication, questioning, decision-making, and practice.

Data Collection: Data will be collected using validated questionnaires for health literacy and CKD prevention behavior at baseline and after the intervention (e.g., at week 12).

Analysis: Descriptive statistics and t-tests (Independent and Paired) will be used to evaluate the program's effectiveness.
