Introduction: Medication adherence remains a significant challenge for individuals with chronic illnesses, particularly those suffering from cardiovascular diseases. Despite various nursing strategies, optimal solutions to this issue have yet to be achieved.
Objective: This study aimed to evaluate the impact of the liaison nurse’s role on improving medication adherence among cardiovascular patients presenting to the emergency department of a selected Aja hospital in Tehran.
Material and Methods: This experimental study employed a post-test-only control group design in 2023. The participants were cardiovascular patients visiting the emergency department of the selected Aja hospital between November and February 2023. Thirty-six patients were purposively selected and randomly divided into experimental and control groups. The experimental group received routine care alongside training and support from a liaison nurse via telephone, while the control group only received routine care. Two weeks after the intervention, medication adherence was measured using the Morisky Medication Adherence Scale (MMAS). Data analysis was performed using SPSS version 19, with a significance level of less than 0.05.
Results: Baseline demographic characteristics did not differ significantly between the two groups (P<0.05). However, two weeks after the intervention, the experimental group demonstrated significantly greater medication adherence )mean score: 6.38±0.91 (compared to the control group) mean score: 4.39±1.64; P>0.001).
Conclusion: The findings underscore the effectiveness of the liaison nurse’s role in enhancing medication adherence among cardiac patients in the emergency department. It is recommended that nursing administrators and healthcare policymakers consider integrating the liaison nurse model into routine hospital care to support patients and improve outcomes.
