Abstract
Objective As children hospitalised with community-acquired pneumonia (CAP) are at risk of persistent chest radiograph (CXR) abnormalities and respiratory sequelae, we investigated factors associated with incomplete CXR resolution at 4 weeks and 12 months post-discharge in children from populations at high-risk of chronic lung disease.
Design Secondary analysis−multicentre, placebo-controlled, randomised controlled trial.
Settings and patients 324 children aged 3 months to ≤5 years hospitalised with radiographic-confirmed CAP were enrolled from seven hospitals in Australia, New Zealand and Malaysia. After 1–3 days of intravenous antibiotics, then 3 days of oral amoxicillin–clavulanate, they were randomised to extended (13–14 days) or standard (5–6 days) courses of antibiotics.
Intervention CXRs were performed at admission, 4 weeks, and 12 months post-discharge and reviewed in a blinded manner.
Main outcome measures Radiographic changes of pneumonia at 4 weeks and 12 months post-discharge compared with admission CXRs.
Results Among children with interpretable CXRs, incomplete resolution was seen in 42/253 (17%) at 4 weeks, and 29/212 (14%) at 12 months. Characteristics at admission associated with incomplete CXR resolution at 4 weeks were previous pneumonia hospitalisation (adjusted odds ratio [ORadj])=6.46, 95% confidence interval [CI] 2.21 to 18.85) and increasing age (ORadj=0.60 per-year, 95% CI 0.38 to 0.94). Continuing respiratory symptoms/signs at 4 weeks post-discharge was also associated with incomplete resolution (OR=5.63, 95% CI 2.38 to 13.32). At 12 months, previous pneumonia hospitalisation was associated with persistent incomplete CXR resolution (OR=4.03, 95 % CI 1.25 to 13.02).
Conclusion In high-risk settings, younger age, those with previous pneumonia hospitalisation, or ongoing respiratory symptoms/signs 4 weeks post-discharge from hospitalised CAP may be associated with incomplete CXR resolution. Consequently, follow-up imaging and monitoring may be warranted in these children.
