Estimating the clinical and economic burden of medically attended influenza in South Korea, stratified by age and comorbidity: A five-season hospital-based surveillance data, 2014/15-2018/19.

ABSTRACT:

Objectives

This study aims to estimate the clinical and economic burden of influenza in South Korea across five seasons (2014/15-2018/19), stratified by age and comorbidity, using data from the Hospital-based Influenza Morbidity and Mortality (HIMM) network.

Methods

Data were gathered from eight university hospitals and included adults (≥ 20 years) with laboratory-confirmed influenza. The catchment population was estimated using hospital and national statistical data. Economic costs were evaluated from a societal perspective.

Results

The incidence of medically attended influenza ranged from 113.1 to 220.7 per 100,000 adults, with hospitalization rate of 35.5 to 76.8, intensive care unit admission at 4.2 to 9.2, and deaths at 1.4 to 3.6. Annual socioeconomic costs rang
