    © 2017 Elsevier Inc. Background: Potential inappropriate medication (PIM) prescribing is a medication that puts patients at risk rather than having benefits. PIM use has been associated with hospitalization, morbidity, and mortality resulting from ADRs in elderly patients. The Lists of Risk Drugs for Thai Elderly (LRDTE) was developed as the new screening tool to identify PIMs use. The prevalence of PIM use using the LRDTE has not been determined in Thailand. Purpose: The main purpose of this study was to examine the prevalence of PIM use based on the LRDTE. In addition, this aimed to address the PIM problem by identifying factors that influenced PIM use among elderly patients in Thailand. Methods: A retrospective cross-sectional descriptive study was conducted using the computerized database at four community hospitals in Thailand during fiscal year 2014. The LRDTE criteria were used as a screening tool for identifying the medicine items of PIM use. Descriptive statistics and multivariate logistic regression were used to identify common and Thai region-specific predictors of PIM use. Results: Of a total of 13274 elderly patients, 79% were prescribed at least one PIM, as indicated by the LRDTE criteria. Amlodipine (32%), omeprazole (30%), and tramadol (18%) were the most commonly prescribed PIMs in elderly patients aged 60 years and older. Hospital and physician characteristics were identified as independent predictors after adjustment for patient and utilization factors. Conclusion: PIM use in Thai elderly patients was highly prevalent in community hospitals because the LRDTE criteria reflected clinical practice in Thailand. Hospital and physician factors were identified as region-specific factors that were highly associated with PIM use. Revision of hospital formularies and educational programs for physicians are needed to improve prescribing and avoid PIM use.
