Objective:
To investigate the correlation between Procalcitonin (PCT) and the CURB-65 score in patients with community-acquired pneumonia at Thong Nhat Hospital.
Subjects and Methods:
A prospective, cross-sectional study of 92 patients with community-acquired pneumonia (CAP), admitted to Thong Nhat Hospital from September 1, 2025, to December 30, 2025. PCT testing and CURB-65 scoring were performed at the time of hospital admission.
Results:
The median age was 76.9 years, with males accounting for 56.5%. The moyen CURB-65 score was 2.42. Common clinical symptoms included fever (87.8%), cough with phlegm (87%), and dyspnea (67.4%). The rate of septic shock was relatively low at 12%. The predominant radiological findings were bilateral alveolar and interstitial infiltrates. The median PCT level was 12.2 ng/mL. Higher CURB-65 scores were associated with higher PCT levels, showing a weak positive correlation (r = 0.239, p = 0.022).
Conclusion:
Community-acquired pneumonia is a common condition in clinical practice. PCT levels show a weak positive correlation with the CURB-65 score. Therefore, multiple indicators should be combined to assess disease severity.
