Medication discrepancies identified by medication reconciliation among patients with acute coronary syndrome.

Medication errors such as medication discrepancies are known as one of the leading cause of death. Medication discrepancies mostly occur during admission and at time transfer of care and discharge. Medication reconciliation process has pivotal role to avert medication discrepancies and improve patient safety and quality. Patients with acute coronary syndrome (ACS) are prone to medication discrepancies due to acute manifestations, simultaneous use of different medicines and having different co-morbidities. This study aimed to determine medication discrepancies identified by medication reconciliation among patients with ACS. In an observational study, patients with ACS admitted to a specialized Hospital in Baneh County, Kurdistan province during September 2023 and January 2024 were included. Medication reconciliation process was done when the patient was admitted. The history of medicine use was collected through interviews with the patient, their caregivers, as well as observing the medicines that were accompany with the patients. Number and type of unintentional medication discrepancies and related factors were evaluated. A total of 280 ACS patients (mean age: 63.8 ± 14.2, male gender: 59.3%) were included in the study. About 68% had at least 2 underlying diseases. The mean daily medicines taken by the patients during admission were 8.5 ± 1.54. The number (percentage) of unintentional inconsistency was observed in 78 (27.3%), and omission (39.7%) and changes in dosage (20.5%) had the highest frequency of unintentional medication discrepancies, respectively. Cardiovascular agents such as anti-dyslipidemia and antiplatelet had the highest frequency of unintentional medication discrepancies. The number of underlying diseases and daily medications before hospitalization increase the odds of discrepancies by 2.15 and 1.49 times, respectively (p-value < 0.05). Medication discrepancies identified by medication reconciliation among patients is relatively common. Unintentional medication discrepancies that have the potential to harm the ACS patients should be given more attention, especially in patients with multiple comorbidities and polypharmacy.
