OBJECTIVES: This study aimed to determine the incidence of unintentional discrepancies (medication errors), types of medication errors with its potential severity of patient harm and acceptance rate of pharmaceutical care interventions.
METHODS: A four-month cross-sectional study was conducted in the general medical wards of a tertiary hospital. All newly admitted patients with at least one prescription medication were recruited via purposive sampling. Medication history assessments were done by clinical pharmacists within 24 hours or as soon as possible after admission. Pharmacist-acquired medication histories were then compared with in-patient medication charts to detect discrepancies. Verification of the discrepancies, interventions, and assessment of the potential severity of patient harm resulting from medication errors were collaboratively carried out with the treating doctors.
RESULTS: There were 990 medication discrepancies detected among 390 patients recruited in this study. One hundred and thirty-five (13.6%) medication errors were detected in 93 (23.8%) patients (1.45 errors per patient). These were mostly contributed by medication omissions (79.3%), followed by dosing errors (9.6%). Among these errors, 88.2% were considered "significant" or "serious" but none were "life-threatening." Most (83%) of the pharmaceutical interventions were accepted by the doctors.
CONCLUSION: Medication history assessment by pharmacists proved vital in detecting medication errors, mostly medication omissions. Majority of the errors intervened by pharmacists were accepted by the doctors which prevented potential significant or serious patient harm.
METHODS: A pre-post intervention study was conducted at medical wards in a public tertiary hospital. During the intervention phase, a structured bedside dispensing process was delineated and conveyed to the doctors, nurses, and pharmacists. Regular verbal reminders were given to the doctors to prioritize discharge patients by producing the prescriptions once discharge decisions had been made and nurses to hand the prescriptions to ward pharmacists and not patients. Throughout the study, ward pharmacists were involved in medication reconciliation via screening of discharge prescriptions and reusing POMs, performed pharmaceutical interventions for any medication errors detected, and provided bedside dispensing with discharge counseling. Comparisons were made between bedside versus counter-dispensing at pre-post intervention phases using the chi-square test.
RESULTS: A total of 1097 and 817 discharge prescriptions were dispensed in the pre-intervention and post-intervention phases, respectively. The bedside dispensing rate increased by 13.5% following remedial actions (p
