Implication

Epidemiological survey reveals peak appendicitis rates in adolescents and higher male risk in the US population, suggesting limited preventive utility for incidental appendectomy.

Key Points

To evaluate the incidence, demographic distributions, temporal trends, and lifetime risks of appendicitis and appendectomy in the United States.
Analyzed data from the National Hospital Discharge Survey spanning 1979 through 1984, including historical trends from 1970 to 1984.
Utilized a life table model to compute the lifetime risk of developing appendicitis and undergoing primary or incidental appendectomy.
Appendicitis incidence peaked in individuals aged 10–19 years (23.3 per 10,000 population/year) and was higher in males (rate ratio 1.4:1), whites (1.5-fold higher than nonwhites), and summer months (11.3% higher than winter).
Incidental appendectomy was highest among females aged 35–44 years (43.8 per 10,000 population/year; 12.1 times the rate in men), whereas overall appendicitis incidence dropped 14.6% between 1970 and 1984.
Estimated lifetime risk of appendicitis was 8.6% for males and 6.7% for females, with approximately 36 incidental appendectomies required to prevent a single case of appendicitis.
