The impact of the COVID-19 pandemic on emergency care of acute myocardial infarction: findings from the Taiwan Clinical Performance Indicator

Abstract

Abstract Acute myocardial infarction (AMI) treatment requires timely diagnosis and treatment for optimal health outcomes. The Coronavirus Disease (COVID-19) pandemic has caused changes in health-care delivery and utilization; therefore, the present study explored the changes in emergency care quality indicators for patients with AMI before and during different periods of government response to the COVID-19 outbreak in Taiwan. The Taiwan Clinical Performance Indicators database was used to evaluate the impact of COVID-19 on acute care quality indicators for patients with AMI during four periods: before the COVID-19 outbreak (Period I–1 January to 31 December 2019) and during three periods in which the central government imposed different levels of epidemic prevention and response alerts (Period II–1 January 2020 to 30 April 2021; Period III–1 May to 31 July 2021; and Period IV–1 August to 31 December 2021). A 15.9% decrease in monthly emergency department admission for patients with AMI occurred during Period III. The hospital ‘door-to-electrocardiogram time being <10 min’ indicator attainment was significantly lower during Periods III and IV. The attainment of ‘dual antiplatelet therapy received within 6 hr of emergency department arrival’ indicator improved in Period IV, whereas ‘the primary percutaneous coronary intervention being received within 90 min of hospital arrival’ indicator significantly decreased during Periods III and IV. The indicator ‘in-hospital mortality’ was unchanged within the study duration. Overall, the quality of care for patients with AMI was mildly influenced during the assessed pandemic periods, especially in terms of door-to-electrocardiogram time of <10 min and primary percutaneous coronary intervention received within 90 min of hospital arrival (Period III). Using our study results, hospitals can develop strategies regarding care delivery for patients with AMI during a COVID-19 outbreak on the basis of central government alert levels, even during the height of the pandemic.
