Exploring the Lived Experiences of Nurses on Barriers and Intervention Strategies in Promoting Medication Adherence Among Patients with Primary Hypertension

This study explored nurses’ lived experiences of barriers and intervention strategies in promoting medication adherence among patients with primary hypertension at Guizhou Provincial People’s Hospital, China. A qualitative descriptive phenomenological design guided semi-structured interviews with ten purposively selected cardiology nurses during the third and fourth weeks of April 2026. Interviews lasted approximately 30–45 minutes. Manual analysis followed Colaizzi’s seven-step method. Seven themes concerned continuous patient education; cultural beliefs, misinformation, and trust deficits; socioeconomic barriers and discharge transitions; routines and caregiver support; trust-based nurse–patient relationships; lifestyle and work–medication misalignment; and treatment complexity and system-based simplification. Interpreted through the Health Belief Model and Social Cognitive Theory, the findings portray adherence support as an ongoing educational, relational, behavioral, and organizational process. The findings informed the Liu Nurse Support Framework for Enhancing Medication Adherence Among Patients with Primary Hypertension, which is recommended for further validation of applicability, feasibility, and effectiveness.
