Senior surgeons and radiologists should assess emergency patients on presentation: a prospective randomized controlled trial.

The objective of this study was to determine whether abdominal ultrasound and plain film radiography (evaluated by senior radiologists) substantially enhances senior surgical assessment in reducing surgical admissions. A randomized controlled trial was carried out in a teaching hospital; ninety-five emergency referrals to general surgery (mean age 51 years, 37% males), presenting with intrabdominal disturbances not requiring immediate surgery, were selected for study. The major outcome measure was the number of patients not admitted as in-patients. Thirty per cent of the intervention group and 10% of the controls did not need admission (95% confidence interval on this 29% difference, 12-38%). There were no important differences in the mean waiting time in casualty (26 min vs. 25 min), length of admission (4.1-5.9 days), surgical intervention (seven vs. 11 patients), readmission with similar pathology within 3 months (seven vs. three patients), and mortality as an in-patient or within 3 months of discharge. Abdominal ultrasound and plain film radiography, assessed by senior radiologists, enhances senior surgical assessment in reducing unnecessary surgical admissions.
