Evaluation of the effectiveness of a perioperative medication reconciliation program in patients scheduled for elective surgery on perioperative medication management protocol adherence.

Ambispective cross-cohort study: prospective cohort (Group A), and retrospective control cohort (Group B) without intervention. Forty eight hours before admission a pharmacist generates a proposal on medication active prior to admission to be maintained/discontinued during the perioperative period according to the hospital protocols. The Pharmacy proposal is validated/modified by an anesthesiologist 24h before admission. At the time of admission, after checking with the patient the medication list, the nurse initiates scheduled medication administration pre and postoperatively. The indicator for program effectiveness assessment is the degree of compliance with perioperative medication management protocols at 24, 48 and 72h of admission for intervention and control cohorts.

Five hundred and three patients were included. One thousand two hundred and eleven pharmacy medication management recommendations were performed in Group A (intervention), of which 94.9% agreed with protocol. In Group B (control before program implementation) action taken by physicians agreed with protocol only in 32.4% of all cases.

The medication reconciliation program significantly increased compliance with the recommendations on chronic medication perioperative management.
