Objective: This study aims to identify inpatient medication problems and analyze the association between patient characteristics and the incidence of the drug-related problem (DRP) experienced by patients.
Methods: The cross-sectional study was conducted at Haji Regional General Hospital, Makassar, using medical record data for inpatients from January to February 2020. Data were collected from September to October 2020. A total of 247 inpatients were identified using the Indonesian version of the Pharmaceutical Care Network Europe.
Results: The most common DRP problem found is the effect of drug treatment not optimal (P1.2) by 35.76% and the most common cause found is no or incomplete drug treatment despite existing indication (C1.6) by 20.16%. Bivariate analysis shows that age, length of stay, and the number of drugs received are significant different with the incidence of DRP in patients (p < 0,01) respectively. Multivariate analysis using logistic regression shows that age, sex, and the number of drugs could significantly affect the incidence of DRP (p<0.05) with the r-square (R2) of 21.6%. According to this model, the largest odds ratio number and the most likely to experience DRP in a patient are age, the number of drugs, then gender (5,2; 4,6; and 2,3).
Conclusion: Age, length of stay, and the number of drugs received affect the DRP incidence in a patient, while gender together with age and the number of drugs affecting the incidence of DRP in a patient.
