Role of Dedicated Cardiac Emergency Unit in Early Identification and Management of Acute Myocardial Infarction in a Developing Country of South Asia

Background The care of patients presenting with chest pain to multidisciplinary services hospital gets compromised due to the busy triage system. A separate and specialized equipped cardiac emergency unit (CAR-ERU) can improve patient’s outcomes. Objectives To enhance early recognition and treatment of acute myocardial infarction (AMI) patients. To sustain key performance quality indicators (KPIs) for AMI. Methods In October 2016, a separate CAR-ERU was established inside the multidisciplinary emergency department (MED). A dedicated specialized heart-lung and vascular teams were hired under the supervision of service line leadership. The KPIs that were identified benchmark with international practice guidelines. Data were collected and stored for analysis. Exemption from the ethical review committee was obtained. Results A total of 2914 patients visited CAR-ERU from October 2016 to September 2017 for a period of one year. Out of which 30% were diagnosed with acute coronary syndrome (ACS) and this included 8% diagnosis with ST-segment elevation myocardial infarction (STEMI). Over 98.8% of the electrocardiogram (ECG) was done within 10 minutes of arrival while aspirin was given to 96.5% of patients within one hour. The door to balloon time (DBT) of <90 min was achieved in 70% of patients. A significant reduction in length of stay in the emergency department and financial burden was noted. Sustainability of major KPI was observed over the subsequent years. Conclusion The introduction of a dedicated CAR-EU improved clinical outcomes, reduced length of stay and financial burden in AMI patients managed in CAR-EU. Our tertiary care hospital is the first one of its kind to take this quality initiative in a lower-middle-income country (LMIC) Pakistan.
