Abstract

Pneumonia and other lower respiratory tract diseases rank as the fourth leading cause of death worldwide. The objective of this study was to examine pneumonia hospitalization patterns, and trends in total pneumonia hospitalization stratified by age group, by type of hospitalization, and by age group in Australia, England, Wales. This study utilized 3 databases to obtain hospital admissions data: the National Hospital Morbidity Database for Australian hospital admissions data, the Hospital Episode Statistics database (HES) for England hospital admissions data, and the Patient Episode Database for Wales. Pneumonia hospitalization data were extracted utilizing J12 to J18 codes. From 2013 to 2020, there were 4,514,444 cases of pneumonia hospitalizations reported in Australia (646,515 [14.32%]), England (3,668,106 [81.25%]), and Wales (199,823 [4.43%]). The most common type of pneumonia hospitalization in Australia, England, and Wales was "pneumonia, organism unspecified," accounting for 77.12%, 95.49%, and 95.75% of the total number of pneumonia hospitalizations in each country, respectively. The most common subtype of pneumonia hospitalization in Australia was "pneumonia, unspecified," accounting for 72.98% of the total number of pneumonia hospitalizations in the country. The most common type of pneumonia hospitalization in England and Wales was "lobar pneumonia, unspecified," accounting for 59.00% and 56.73% of the total number of pneumonia hospitalizations in each country, respectively. Most pneumonia hospitalizations in Australia, England, and Wales were non-same-day hospitalizations, accounting for 90.78%, 99.91%, and 99.95%, respectively. Pneumonia hospitalizations in Australia, England, and Wales were directly related to age. Males accounted for most pneumonia hospitalizations in Australia, England, and Wales. This study highlighted that hospitalization rate for pneumonia increased during the past decade in Australia, England, and Wales. The age and male gender were clearly contributing factors that affected pneumonia hospitalizations rate. Educational campaign aiming to increase public knowledge of pneumonia, its risk factors, and lifestyle modification should be prioritized to decrease pneumonia episodes.
