Overview
Epidemiology and demographics
Incidence and prevalence
The incidence and prevalence of empyema has been increasing over the past 15 years. More than 40% of patients have preexisting comorbidities.[1]
There have been a 26% increase in age and sex-standardized incidence rate from 8.7 per 100,000 person-years in 1997 to 11.8 per 100,000 person-years in 2011.[1] This increment is most notably among older people aged ≥ 80 years (87.3% [from 20.4 per 100,000 in 1997 to 38.2 per 100,000 in 2011]) compared with people aged 40 to 64 years (27.8% [from 10.7 per 100,000 in 1997 to 12.6 per 100,000 in 2011])[1]
Age
Gender
Men are more commonly affected with empyema than women. The male to female ratio is approximately 1.7- to 3.1-fold higher in men than in women.[1]
Developed and developing countries
The rate of patients with empyema requiring hospitalization appear to be increasing in western populations, however updated population-based data are sparse. The few existing population-based studies of Available data on adult empyema have reported increases between 30% and 97% over the past decades in the United States and Canada. Most of these studies were conducted in large referral centers only.[1][2]
The median length of hospital stay however is decreasing from 22 days 17 days.[1]
