Area of Science:

  • Otolaryngology
  • Infectious Diseases
  • Health Services Research

Background:

  • Otitis externa is a prevalent and painful outer ear canal infection.
  • Limited data exists on current US treatment practices for otitis externa.
  • Understanding treatment patterns is crucial for optimizing patient care.

Purpose of the Study:

  • To examine current treatment patterns for otitis externa in the United States.
  • To identify variations in treatment based on patient demographics and physician specialty.
  • To assess the appropriateness of prescribed medications.

Main Methods:

  • Analysis of data from the 1993 National Ambulatory Medical Care Survey (NAMCS) and National Hospital Ambulatory Medical Care Survey (NHAMCS).
  • Inclusion of adult and pediatric patients diagnosed with otitis externa.
  • Examination of physician visit reasons, diagnoses, physician types, payment sources, procedures, medications, and patient disposition.

Main Results:

  • Treatment patterns for otitis externa differ significantly between adults and children, and by physician specialty.
  • Despite infrequent severe classifications and few concomitant diagnoses, 40% of patients received both topical and systemic medications.
  • Many prescribed oral antibiotics lacked activity against common otitis externa pathogens like Staphylococcus aureus and Pseudomonas aeruginosa.

Conclusions:

  • Topical antibiotic treatment is generally sufficient for localized otitis externa, negating the need for systemic medications.
  • Systemic antibiotic use increases costs, potential side effects, and may reduce patient compliance.
  • Optimizing otitis externa treatment can improve outcomes and reduce healthcare resource utilization.
