Epididymitis rates in Australian hospitals 2009-2018: ecological analysis

Abstract

OBJECTIVES: To investigate rates of acute epididymitis diagnosed in Australian hospital settings. METHODS: Yearly hospital admission and emergency department (ED) rates of epididymitis as primary diagnoses were calculated for 15-44-year-old men for three states (Victoria, New South Wales, Queensland) from 2009 to 2014 using population denominators. Zero inflated Poisson regression models were used to analyse variation in rates by year, age, and residential area. Additionally, we investigated national epididymitis admission trends from 2009 to 2018 using generalised linear models. RESULTS: Between 2009 and 2014, there was a total of 7375 admissions and 17 281 ED presentations for which epidid..
