INTRODUCTIONSchizophrenic illnesses are typically long term illnesses. Nonadherence to medication can lead to relapse, which can mean more visits to the emergency room, rehospitalizations and increased need for clinician intervention -all of which lead to increased costs to healthcare systems.
1Rates of non-compliance in psychotic disorders have been reported to vary from 11 to 80% and in most of the cases it would result in relapse.2,3 Nonadherent patients have an average risk of relapse that is 3.7 times greater than that of adherent patients. 4 As per World Health Organization (WHO) estimates the median treatment gap for schizophrenia, including other non-affective psychosis, was 32.2 % and so the poor adherence results in wastage and under utilization of already limited treatment resources and compounds the challenges of improving health in poor populations. 5 Weiden and Olfson found that nonadherence in schizophrenia accounted for about 40% of the annual costs of rehospitalization.6 Johnson et al, reported that patients with schizophrenia who experienced a relapse did not return to their pre relapse level of social adjustment 1 year after recovery, implying that the cost of relapse is much greater than just the cost of rehospitalization.7 The cost of relapse may be particularly severe for patients with jobs and family responsibilities since they have the most to lose. Knowledge of how to improve adherence ABSTRACT Background: Nonadherence with medication regimens is among the most common causes of psychotic relapse and the need for rehospitalisation. This study was designed to look into the factors affecting attitude towards medication adherence in Schizophrenia and its relationship with severity of illness, side effects of medication. Methods: Adult males and females in the age range of 18-55 years fulfilling criteria for schizophrenia according to ICD -10, DCR, and reporting at outpatient department were taken up for this study. Severity of illness was assessed by Brief Psychiatric Rating Scale (BPRS), Side effects to medication were assessed by Udvalg for Kliniske Undersogelser (UKU) side effect scale, and Adherence was assessed by Medication adherence rating scale (MARS). Results: Adherence negatively correlated with severity of illness, and side effects in the form of increased sleep duration, asthenia, increased fatigability, lassitude and diminished sexual desire. Regression analysis with MARS as dependent variable showed side effects of medication in the form of increased sleep duration in followed by asthenia, lassitude, and increased fatigability to be predictors of poor adherence in the sample. Conclusions: Poor adherence is associated with severity of schizophrenia, sedation and asthenia like side effects due to medication. Sedation and asthenia like side effects caused a decline in adherence.
