Summary
Pneumonia is a frequent reason for emergency department (ED) visits in Alberta, Canada. Study reveals decreasing pneumonia ED visit rates over six years, with disparities in presentation and low early follow-up rates.
Area of Science:
- Public Health
- Epidemiology
- Emergency Medicine
Background:
- Pneumonia is a significant respiratory infection and a common reason for emergency department (ED) visits.
- Understanding the epidemiology of pneumonia presentations is crucial for public health planning and resource allocation.
Purpose of the Study:
- To describe the epidemiology of pneumonia presentations to EDs in Alberta, Canada.
- To analyze trends, demographics, and follow-up care for pneumonia patients in Alberta EDs.
Main Methods:
- Utilized provincial administrative databases for ED encounters related to pneumonia over six fiscal years (1999-2005).
- Extracted data on patient demographics, visit timing, and subsequent healthcare utilization.
- Employed descriptive summaries and directly standardized visit rates for data analysis.
Main Results:
- Recorded 190,896 ED visits for pneumonia by 140,913 individuals.
- Observed a decrease in standardized visit rates from 12.5/1,000 to 9.1/1,000 population between 1999-2000 and 2004-2005.
- Found that 28.2% of cases were admitted, 4.8% of discharged patients had a repeat ED visit within 7 days, and the median time to first non-ED follow-up was 21 days.
Conclusions:
- Pneumonia remains a common ED presentation in Alberta, with notable variations.
- Identified a declining trend in presentations after the first year, alongside disparities based on age, sex, and socioeconomic status.
- Highlighted a low rate of early non-ED follow-up among pneumonia patients.

01:30Pneumonia V: Nursing management and Prevention
Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.

01:29Pneumonia I: Introduction
Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
01:30Pneumonia I: Introduction
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
