Abstract
OBJECTIVES: Necrotising otitis externa is a serious infective condition with significant risk of complications and a profound impact on patients' quality of life. METHODS: A quantitative descriptive study was undertaken using epidemiological data from the National Health Service Hospital Episode Statistics database and other national databases. Data correlating with reported cases 2002-2024 were compiled and analysed. RESULTS: The national incidence of necrotising otitis externa has demonstrated a sustained increase 2002-2024. The 30 per cent incidence drop during the coronavirus disease 2019 pandemic may be attributable to reduced exposure to risk factors, reduced contact between susceptible patients and health professionals and pandemic-related deaths of at-risk populations. There remains a strong correlation between growths in necrotising otitis externa incidence, the ageing population and national incidence of diabetes mellitus. These are all projected to continue to rise. Antibiotic resistance is not a significant contributing factor. CONCLUSION: This study demonstrates several significant trends, offering a strong foundation for deeper exploration in future studies.
