Key result
Significant abnormalities on preoperative chest roentgenograms were present in 62% of high-risk elderly patients versus 34% of those without clinical risk factors (P<0.05).
Why the study?
Does routine preoperative chest roentgenogram identify significant abnormalities and predict postoperative complications in elderly patients?
Population
136 preoperative patients over the age of 59 years

Higher yield in high-risk elderly; leaves open whether routine preoperative chest X-rays predict complications or warrant broad use.

Does routine preoperative chest roentgenogram identify significant abnormalities and predict postoperative complications in elderly patients?
Absolute Event Rate: 62% vs 34%
p-value: p=<0.05
Routine preoperative chest X-rays frequently reveal significant abnormalities in elderly patients, particularly those over 70, regardless of clinical history, supporting their routine use in this population.
Boghosian et al. (1987) conducted an observational in Preoperative evaluation (n=136). High clinical risk factors vs. No clinical risk factors was evaluated on Significant abnormalities on chest roentgenograms (p=<0.05). Significant abnormalities on preoperative chest roentgenograms were present in 62% of high-risk elderly patients versus 34% of those without clinical risk factors (P<0.05).
