Abstract
BACKGROUND: Despite global consensus on the management of acute coronary syndrome (ACS), implementation of strategies to improve adherence of guideline-directed medical therapy (GDMT) remains sub-optimal, especially in developing countries. Thus, we aimed to assess the effect of clinical pharmacist-led clinical audit to improve the compliance of discharge prescriptions in patients admitted with ACS. It is a prospective clinical audit of ACS patients which was carried out for 12 months. The discharge prescriptions were audited by clinical pharmacists for the appropriateness in the usage of statins, dual antiplatelet therapy (DAPT), beta-blockers, and angiotensin-converting enzyme inhibitors (ACE-I)/angiotensin receptor blocker (ARB). A feedback report was presented every month to the cardiologists involved in the patient care, and the trend in the adherence to GDMT was analyzed over 12 months. RESULTS: The discharge prescriptions of 1072 ACS patients were audited for the justifiable and non-justifiable omissions of mandated drugs. The first-month audit revealed unreasonable omissions of DAPT, statin, ACE-I/ARB, and beta-blockers in 1%, 0%, 14%, and 11% respectively, which reduced to nil by the end of the 11th month of the audit-feedback program. This improvement remained unchanged until the end of the 12th month. CONCLUSIONS: The study revealed that periodic clinical audit significantly improves adherence to GDMT in patients admitted with ACS.
