THE EFFECT OF VILLAGE HEALTH VOLUNTEERS TRAINING PROGRAM BY PHARMACISTS TO PROMOTE MEDICATION ADHERENCE AMONG SCHIZOPHRENIA PATIENTS IN THE COMMUNITY
Keywords:schizophrenia, village health volunteers, medication adherence, beliefs about medication
This quasi-experimental study aimed to examine the effect of a village health volunteer training program on promoting medication adherence and specific beliefs about medication. Participants were schizophrenia patients at Bencharak Hospital, Srisaket Province with a history of medication non-adherence. The researchers purposively assigned conditions to two groups. The experimental group (14 participants) received home health care from trained village health volunteers and the control group (15 participants) received usual care. Medication adherence outcome was evaluated by the pill count method. Specific beliefs about medication were evaluated by questionnaires regarding necessary beliefs and concerns about medication at the baseline, 1 and 3 months of care. Independent t-test, Mann-Whitney U test and Generalized Estimating Equation (GEE) were used for data analysis. The results showed that there was no significant difference between the two groups at the baseline. Over three months of care and after the baseline was adjusted, the mean of medication adherence (9.09%; 95%CI: 5.00 – 13.18) and necessity belief about medication scores (1.52 scores out of 25; 95%CI: 0.72 – 2.33) in the experimental group were significantly higher than in the control group, respectively. Moreover, the concerns about medication score was significantly lower, 1.18 out of 25, (95%CI: -1.97 - -0.39) than the control group. Furthermore, at the end of the program, village health volunteers had significantly higher knowledge of caring for schizophrenia patients than before training (p=0.002). Therefore, the village health volunteer training program to promote medication adherence among schizophrenia patients in the community improved medication adherence, necessary belief about medication, decreased concern about medication and improved village health volunteers’ knowledge of caring for schizophrenia patients.
