Abstract
Aim: To evaluate the accuracy and completeness of patient‐completed medication histories to those obtained by a pharmacist in a pre‐admission surgical clinic.Method: This prospective study was conducted over 3‐weeks with patients attending a pre‐admission surgical clinic. Consecutive patients had a pre‐admission assessment with the pre‐admission clinic pharmacist. Comparison was made regarding the accuracy of information between patient‐completed medication history and assessment by the pre‐admission clinic pharmacist.Results: 150 patients were enrolled −33 (22%) had a patient‐completed questionnaire that was totally correct. There was an average of 3.9 drug discrepancies per patient‐completed medication history. The discrepancies included: omitted drugs (317), incorrect doses (24), doses omitted (110), dosing frequency incorrect (24) or dosing frequency omitted (63). The adverse drug reaction status was recorded correctly on 85% of patient‐completed medication histories.Conclusion: Patient‐completed medication histories used in a pre‐admission surgical clinic were not accurate in 4 out of 5 patients. Pharmacists in a pre‐admission clinic can ensure the availability of an accurate medication history.
