Background:
Community-acquired pneumonia (CAP) is a major cause of morbidity and mortality in Nigeria. Severity assessment is a major starting point in the proper management of CAP. The BTS guideline for managing this condition is simple and does not require sophisticated equipment. Adherence to this guideline will improve CAP management in Nigeria.
Aims:
To assess the usefulness of the CURB-65 score in the management of CAP patients in Nigeria and to determine the outcome in relation to the degree of severity using CURB-65.
Methods:
A prospective observational study of 80 patients with CAP was carried out in the University of Nigeria Teaching Hospital Enugu, Nigeria from December 2008 to June 2009. The patients were classified into three risk groups and the ability of the CURB-65 score to predict the 30-day mortality rate and the need for ICU admission was determined.
Results:
Eighty patients were recruited, 39 of whom were men, giving a male to female ratio of 1:1.05. The mean age was 56 ± 18 years. Thirty-seven patients (46.3%) were outpatients, 13 with CURB score 0, 21 with CURB score 1, two with CURB score 2, and one with CURB score 3. Of the 43 patients (53.7%) admitted to hospital, six, 13, 14, and 10 had scores of 4, 3, 2, and 1, respectively. The ICU admission rate was 10%. Twelve patients died, 2.2% in the low-risk group, 12.5% in the intermediate-risk group, and 45% in the high-risk group.
Conclusions:
The CURB-65 score is a simple method of assessing and risk stratifying CAP patients. It is particularly useful in a busy emergency department because of its ability to identify a reasonable proportion of low-risk patients for potential outpatient care.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:

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.
