Abstract：
BACKGROUND:Chest radiography is widely used in children with acute lower respiratory infections, but the benefits are unknown. OBJECTIVES:To assess the effects of chest radiography for children with acute lower respiratory infections. SEARCH STRATEGY:The searches were updated in November 2004. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 1, 2005), MEDLINE (1966 to February, Week 1 2005) and EMBASE (January 1990 to September 2004). We contacted experts in the fields of acute respiratory infections and paediatric radiology to locate additional studies. SELECTION CRITERIA:Randomised or quasi-randomised trials of chest radiography in children with acute respiratory infections. DATA COLLECTION AND ANALYSIS:One reviewer extracted data and assessed trial quality. MAIN RESULTS:We identified only one trial of 522 participants, which was performed by the review authors. The participants were ambulatory children aged two months to five years. Forty-six per cent of both radiography and control participants had recovered by seven days (odds ratio (OR) 1.03, 95% confidence interval (CI) 0.64 to 1.64). Thirty-three per cent of radiography participants and 32% of control participants made a subsequent hospital visit within four weeks (OR 1.02, 95% CI 0.71 to 1.48). Three per cent of both radiography and control participants were subsequently admitted to hospital within four weeks (OR 1.02, 95% CI 0.40 to 2.60). There were no deaths in either group. AUTHORS' CONCLUSIONS:There is no evidence that chest radiography improves outcome in ambulatory children with acute lower respiratory infection. The findings do not exclude a potential effect of radiography, but the potential benefit needs to be balanced against the hazards and expense of chest radiography. The findings apply to ambulatory children only.
