Abstract

BACKGROUND:

Pneumonia is an infection of the lung and a common presentation problem in EDs. The objective of this study was to describe the epidemiology of pneumonia presentations to EDs in the province of Alberta, Canada.

METHODS:

Provincial administrative databases were used to obtain all ED encounters for pneumonia during 6 fiscal years (April 1999 to March 2005). Information extracted included demographics, ED visit timing, and subsequent visits to non-ED settings. Data analysis included descriptive summaries and directly standardized visit rates.

RESULTS:

A total of 190,896 ED visits for pneumonia were made by 140,913 distinct individuals (average of 1.4 visits per individual). Most (80.6%) had only one pneumonia-related ED visit. Male patients presented in slightly higher numbers than female patients. Standardized visit rates decreased overall from 12.5/1,000 population in 1999-2000 to 9.1/1,000 in 2004-2005. Admission occurred in 28.2% of the cases. In a discharged subset, 4.8% had a repeat ED visit within 7 days. Overall, 67.0% of individuals had yet to have a non-ED follow-up visit by 1 week; the estimated median time to the first follow-up visit was 21 days (95% CI, 20-22).

CONCLUSIONS:

Pneumonia is a common presenting problem in Alberta EDs, and further study is required to understand the factors associated with the variation in presentations. Findings include a decrease in presentations after the first fiscal year, disparities based on age, sex, and socioeconomic/cultural status, and a low rate of early follow-up.
