The impact of readiness to discharge from hospital on adherence to treatment in patients after myocardial infarction

Abstract

Background: The healthcare professionals involved in in-hospital treatment of myocardial infarction (MI) are also responsible to patients for their education before leaving the hospital. This education aims to modify patient behaviour in order to reduce relevant risk factors and improve self-control and adherence to medications. The aim of the study was to analyse the relationship between readiness for discharge from hospital and adherence to treatment at follow-up in MI patients. Methods: An observational, single-center, MI cohort study with 6-month follow-up was conducted between May 2015 and July 2016. The Readiness for Hospital Discharge after Myocardial Infarction Scale (RHD-MIS) and the Adherence in Chronic Diseases Scale (ACDS) were applied. Results: Two hundred and thirteen patients aged 30–91 years (62.91 ± 11.26) were enrolled in the study. The RHD-MIS general score ranged from 29 to 69 points (51.16 ± 9.87). A high level of readiness was found in 66 (31%) patients, intermediate in 92 (43.2%), and low in 55 (25.8%) of patients. Adherence level assessed with the ACDS 6-months after discharge from hospital ranged from 7 to 28 points (23.34 ± 4.06). An increase in objective assessment of patient knowledge according to RHD-MIS subscale resulted in significantly higher level of adherence at the follow-up visit (p = 0.0154); R Spear-man = 0.16671, p = 0.015; p for trend = 0.005. During the 6-month follow-up 3 (1.41%) patients died and 17 (7.98%) were hospitalized for a subsequent acute coronary syndrome. Conclusions: This study provided preliminary evidence of a long-term association between the results of assessment of readiness for discharge from hospital and adherence to treatment in patients after MI.
