title: The barium enema scout film: cost effectiveness and clinical efficacy.
abstract: The authors prospectively evaluated 1,001 consecutive double-contrast barium enema examinations to determine the efficacy of the preliminary film. The scout films were evaluated for the presence of unsatisfactory amounts of residual feces and clinically significant extracolonic abnormalities. The contrast studies were independently evaluated in a double-blind manner for satisfactory colonic preparation as well as extracolonic abnormalities. The routine use of the scout film resulted in an increase in health care charges and departmental costs. In addition, there was no significant increase in the detection of extracolonic abnormalities. Our data suggest that routine use of scout films prior to contrast studies is unnecessary, although selective use in some clinical situations may be justified.
