Abstract
OBJECTIVES:
Little is known about the economic burden of influenza-related hospitalisations in Japan. This study sought to identify the factors that contribute to the total health care costs associated with hospitalisations due to influenza in the Japanese population.
STUDY DESIGN:
A retrospective cross-sectional database analysis study.
METHODS:
A structural equation modelling approach was used to analyse a nationwide Japanese hospital claims data. This study included inpatients with at least one confirmed diagnosis of influenza and with a hospital stay of at least 2 days, who were admitted between April 2014 and March 2015.
RESULTS:
A total of 5,261 Japanese inpatients with a diagnosis of influenza were included in the final analysis. The elderly (≥ 65 years) and the young (≤ 15 years) comprised more than 85% of patients. The average length of stay (LOS) was 12.5 days, and the mean total health care cost (THC) was 5,402 US dollars (US$) per hospitalization. One additional hospital day increased the THC by 314 US$. Intensive care unit (ICU) hospitalisations were linked to higher costs (+4,957 US$) compared to regular hospitalisations. The biggest procedure-related cost drivers, which were also impacted by LOS, were blood transfusions (+6,477 US$), tube feedings (+3,501 US$), and dialysis (+2,992 US$).
CONCLUSIONS:
In Japan, the economic burden due to influenza related hospitalisations for both children and the elderly is considerable and is further impacted by associated comorbidities, diagnostic tests and procedures that prolong the length of stay.
