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.

OBJECTIVE Systemic-to-pulmonary artery shunts are amongst the most common palliative procedures performed in neonates with congenital heart defects. These procedures require immediate postoperative thromboprophylaxis to prevent life-threatening shunt thrombosis. The novel use of intravenous P2Y12 platelet receptor antagonists has led to a need for dosing recommendations and monitoring. This study aims to determine cangrelor dosing in neonates through laboratory assessment of P2Y12 receptor reactivity and adverse events. METHODS Observational retrospective cohort study on the use of cangrelor for thromboprophylaxis in the immediate postoperative period of neonates undergoing placement of systemic-to-pulmonary artery shunts in a tertiary children's hospital from March 2020 to March 2021. RESULTS Ten neonates receiving cangrelor post systemic-to-pulmonary artery shunt placement were included in the study. Median age and weight were 4 days (IQR, 2.75–5.25) and 3.49 kg (IQR, 3.1–3.75), respectively. Five (50%) patients received a 3.5-mm shunt, while the remaining patients received a 4-mm shunt. For thrombin inhibition, 5 (50%) patients received heparin and 5 (50%) received bivalirudin. Median cangrelor dose was 0.1 mcg/kg/min (IQR, 0.1–0.1). Median achieved P2Y12 reaction units (PRU) at this cangrelor dose was 127.5 (IQR, 72.5–173.75). No shunt thrombosis occurred in these patients; however, there was 1 minor hemorrhagic event. CONCLUSIONS Our study suggests that a cangrelor dose of 0.1 mcg/kg/min is associated with therapeutic PRU and prevents shunt thrombosis in neonates post systemic-to-pulmonary artery shunt, with minimal hemorrhagic complications.
