Nationwide Trends in Incidence, Healthcare Utilization, and Mortality in Hospitalized Acute Myocardial Infarction Patients in Taiwan

Novartis Pharmaceuticals124,018 enrolled

Overview

This was a retrospective study using the Taiwan's National Health Insurance Research Database (NHIRD). The study employed two study designs for different purposes as follows: * A cross-sectional analysis was conducted to explore the annual incidence trends. * A longitudinal cohort study was conducted to assess baseline characteristics, treatment patterns, long-term healthcare utilization, and cause-specific mortality among incident AMI patients. In each part, the study was conducted for AMI, and separately for ST-segment elevation and non-ST- segment elevation myocardial infarction (STEMI and NSTEMI)

Inclusion Criteria: Cross-sectional analysis: * Patients aged 20 years and older. * Patients who had been admitted for AMI, defined as primary or first secondary diagnosis of AMI between 2014 and 2020. * The diagnosis of AMI/ STEMI/ NSTEMI was identified by the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes and 10th revision (ICD-10-CM) codes. * Incident cases of AMI hospitalization were defined as no history of AMI-related hospitalization or outpatient visit within 1 year before admission. Longitudinal analysis: Patients aged 20 years and older. * Patients who had been admitted for AMI, defined as primary or first secondary diagnosis of AMI between 2014 and 2017. * The diagnosis of AMI/ STEMI/ NSTEMI was identified by ICD-9-CM codes and ICD-10-CM codes. (The ICD-9-CM code and ICD-10-CM codes were the same as above) * Incident cases of AMI hospitalization were defined as no history of AMI-related hospitalization or outpatient visit within 1 year before admission. * The cohort entry date was defined as the admission date of incident AMI hospitalization, and the index date was defined as the discharge date of incident hospitalization.
