Randomized Controlled Trial Comparative Study Clinical Trial
Outpatient internal medicine preoperative evaluation: a randomized clinical trial.
The purpose of this study was to evaluate the effect on resource use of a program outpatient internal medicine preoperative evaluation in a two arm parallel design randomized clinical trial. In a tertiary care teaching Veterans Affairs hospital, 355 patients (179 inpatient arm, 176 outpatient arm)(mean age 65.5 years) were referred for internal medicine preoperative evaluation before elective surgery. Outpatient internist preoperative evaluation was performed 2 to 3 weeks before admission for surgery in the experimental arm with preoperative laboratory and radiology testing performed during the visit. ⋯ Patients health status after discharge and satisfaction with care were not different between the two arms of the investigation. A program of outpatient internal medicine preoperative evaluation significantly reduced preoperative length of stay with a lesser effect on total length of stay. Unnecessary admission of patients for elective surgery were reduced by this program.
