Purpose: Medication adherence is crucial but also challenging in managing psychiatric disorders. Non-adherence to medication regimens in schizophrenia has been shown to be a large contributor to relapse and hospitalization. It is essential to identify non-adherence and understand the factors that lead to non-adherence in patients with psychiatric disorders. There are not many methods to assess a patient’s adherence. This study will identify patients with poor medication adherence and attempt to identify factors that contribute to non-adherence. The purpose of this study is to determine factors where possible interventions can be made.
Methods: A retrospective evaluation will be used to measure patients' medication adherence. Prescription data from patients’ medical records will be used to calculate each patient’s medication possession ratio (MPR) for the past year. Medication possession ratio is a ratio of the number of doses dispensed relative to the dispensing period. Based on prior studies, an 80 percent cutoff will be used to divide patients into adherent and non-adherent. A survey will be provided to patients to obtain a patient-reported measure of adherence. The survey will also assess factors that may affect adherence, including (1) socioeconomic factors, (2) factors associated with the health care team and system in place, (3) disease-related factors, (4) therapy-related factors, and (5) patient-related factors. Healthcare burden will be measured by looking at the frequency of use of inpatient and outpatient services during the same time-period. Later interventions may be made with individual patients. Adherence, healthcare burden, and patient outcomes will be assessed.
