Comparative Study of X-Ray and Sonographic Findings in Pneumonia in a Tertiary Hospital: A Cross-Sectional Study in Nepalese Adults
Abstract
INTRODUCTION
Pneumonia poses a significant global health concern, particularly in developing nations, necessitating accurate and accessible diagnostic methods. Chest x-ray is the conventional imaging modality, albeit with radiation exposure risks. Lung ultrasonography offers a radiation-free alternative and is increasingly used for pneumonia diagnosis, especially in critical care settings. This study aimed to compare the diagnostic capabilities of chest x-ray and lung ultrasonography in nepalese adults with pneumonia, focusing on sensitivity in detecting specific pneumonia features such as consolidation with air bronchogram and pleural effusion.
MATERIAL AND METHODS
A cross-sectional observational study was conducted at a tertiary hospital in Nepal between September 2022 and September 2023. Participants clinically diagnosed with pneumonia underwent both chest x-ray and lung ultrasonography within 24 hours. Data on demographics, symptoms, physical examination, and imaging results were collected and statistically analyzed.
RESULTS
Among 77 participants, predominantly males with a mean age of 54.86 years, pneumonia was detected in 98.7% and 96.1% of cases through ultrasound and x-ray respectively. Ultrasonography exhibited superior sensitivity in identifying consolidation with air bronchogram (67.5% vs. 45.5%) and pleural effusion (55.8% vs. 31.2%) compared to x-ray. Statistical analysis showed significant differences in the detection of consolidation with air bronchogram…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 77 participants or records.
