Impact of reminder on medication adherence: a structural equation model, based on study in Sikkim, India

Abstract

The problem of medication non-adherence has persisted over decades. The rate of adherence decreases with time and improvement in health condition. When patients cannot follow their prescribed medication regime, it leads to deterioration of their health condition and increases their financial costs. This research aims to find the effect of reminder on medication adherence behaviour of patients when “Acceptance of Side Effect”, “Quality of Life” and “Medication Beliefs” act as mediators. The sample size of the research was 505. Sampling units comprised patients suffering from different diseases in Central Referral Hospital, Sikkim, India. By developing a Structural Equation Model, the effect of reminder on the mediators and adherence was analysed. The results show a significant positive association between reminder and the three mediators. Reminder has a significant positive effect on adherence (β=0.637, e=0.055, p=0.001). The effect is higher in the presence of mediators (β=0.7, e=0.037, p=0.001).
