Key result
Presence of identifiable clinical risk factors was associated with a 22% rate of serious abnormalities on preoperative chest roentgenograms, compared to 0.3% in patients without risk factors.

Supports selective preoperative chest radiography based on risk factors; leaves open prospective validation of clinical impact.

Can clinical criteria identify surgical admissions who are unlikely to have abnormal preoperative chest roentgenograms?
Absolute Event Rate: 22% vs 0.3%
Clinical criteria can reliably identify preoperative patients who are very unlikely to have abnormal chest roentgenograms, potentially reducing unnecessary routine screening.
Lloyd Rucker (1983) conducted an observational in Preoperative surgical admissions (n=905). Identifiable clinical risk factors vs. No clinical risk factors was evaluated on Serious abnormalities on preoperative chest roentgenogram. Presence of identifiable clinical risk factors was associated with a 22% rate of serious abnormalities on preoperative chest roentgenograms, compared to 0.3% in patients without risk factors.
