  "abstract": "Background Upon admission to the hospital, patients' home medications are often substituted with those from the hospital formulary. An alternative is Patients' Own Medication (POM), allowing patients to bring their own medications from home. If POM runs out or new medications are prescribed, the hospital supplies identical medications for use after discharge. This may cause an imbalance between the home and hospital medication budgets. Using POM in the hospital results in overpayment from the home medication budget. In contrast, using hospital-provided medication after discharge results in overpayment from the hospital medication budget. This imbalance could hinder the implementation of POM. However, hospitals can adjust the amount of medication supplied to offset overpayment from the home medication budget. Therefore, this study simulates the impact of two medication supply strategies on the balance between overpaid costs from the home and hospital medication budgets.Methods A total of 200 patients (>18 years) were included across two hospitals. In supply strategy 1, both new and resupplied medications were provided for 14 days. In strategy 2, new medications were provided for 14 days, while resupplied medications were provided for 28 to 30 days. The primary outcome was the difference in overpaid costs between the two budgets, calculated per patient per admission.Results For strategy 1 (the provision of resupply medication for 14 days), the median cost difference per patient per admission was -€3.48 (range -€198.27 to €293.40), indicating a small overpayment by the hospital. When resupply medication was provided for 28 to 30 days, the median overpayment per patient per admission increased slightly to -€4.12 (range -€315.87 to €293.40).Conclusion Implementing POM results in only a small difference in overpaid costs between home and hospital medication budgets, regardless of the supply strategy. Consequently, this does not hinder the implementation of POM in hospitals.",
