One Year Evaluation of Pharmacist Medication Charting Service in a Principal Referral Women and Newborn Hospital

Background: Accuracy of medication charts on admission to hospital has previously shown that inadvertent omission of therapy was the most common discrepancy, accounting for 40% to 60% of errors. Partnered Pharmacist Medication Charting (PPMC) has shown to reduce medicationrelated problems. Objective: The aim of this study was to evaluate the implementation of Pharmacist Medication Charting (PMC), a derivative of PPMC, in a maternity and gynecological hospital. The occurrence of medication omission identified by the pharmacists was assessed and the pharmacist interventions involving PMC analyzed. Methods: The pharmacist interventions documented from 1st July 2022 to 30th June, 2023 were evaluated using PowerBI for data and trends on the Medication-Related Problems (MRPs) identified, occurrence of PMC, common medications charted by the pharmacists and the pharmacist recommendation and action following the identification of MRPs. Results: A total of 4898 pharmacy interventions was documented in the 12-month period. Of the total interventions documented, 1321 (26.97%) were related to pharmacist medication charting. Of all the interventions related to PMC, 53.29% involved pharmacists charting medications for the continuation or initiation of over-the-counter medications, 13.32% involved pharmacist partnered charting of Prescription Only Medications and Controlled Medications with medical staff, and 33.3% were referred to a credentialled pharmacist for PMC service. With regards to action taken following interventions involving PMC, 1065 (80.62%) were resolved following PMC. Common medications charted by the pharmacists include: macrogol and docusate laxatives (288), pregnancy multivitamin containing iron, iodine and folate (169), colecalciferol (133), iron (127), asthma inhaler (99), paracetamol and ibuprofen (88), nicotine (38), calcium (29), folic acid (26), and pantoprazole (15). Conclusion: Our study demonstrated that hospital pharmacists contribute to the reduction of MRPs, and PMC enables pharmacist to address prescribing omission and conditions untreated in the hospital. This study also reflects skills enhancement in practice for clinical pharmacists and resulted in successful implementation of PMC.
