Summary

Nasal bleeding (epistaxis) affects 6 per 10,000 annually, primarily older adults. Posterior nosebleeds and rebleeding risk increase with age, highlighting the need for targeted interventions.

Area of Science:

  • Otolaryngology
  • Emergency Medicine
  • Epidemiology

Context:

  • Epistaxis (nosebleeds) represent a significant portion of Ear, Nose, and Throat (ENT) emergencies.
  • Accurate incidence calculation is challenging due to low rates of seeking medical attention.

Purpose:

  • To determine the incidence, characteristics, and risk factors of epistaxis in a defined population.
  • To analyze seasonal variations and the prevalence of anterior versus posterior nosebleeds.
  • To investigate rebleeding rates and their correlation with patient age and epistaxis localization.

Summary:

  • The study recorded an epistaxis incidence of 6 cases per 10,000 person-years, with 13.3% of ENT emergencies attributed to nasal bleeding.
  • The majority of patients (57.3%) were over 50 years old, with a notable increase in posterior epistaxis among those over 40.

  • Rebleeding occurred in 18% of cases, with higher rates observed in older patients and those with posterior epistaxis.

    • Impact:

    • Provides crucial epidemiological data on epistaxis, aiding in resource allocation for emergency departments.
    • Highlights the increased risk of posterior epistaxis and rebleeding in elderly populations, informing clinical management strategies.
    • Contributes to understanding the underlying mechanisms of epistaxis, including male predominance and seasonal influences.
