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.

A significant portion of health care resources are spent in intensive care units with, historically, up to two-fold variation in risk-adjusted mortality. Technological, demographic, and social forces are likely to lead to an increased volume of intensive care in the future. Thus, it is important to identify ways of more efficiently managing intensive care units and reducing the variation in patient outcomes. ⋯ Furthermore, units with greater technological availability are significantly more likely to be associated with hospitals that are more profitable, involved in teaching activities, and have unit leaders actively participating in hospital-wide quality improvement activities. The findings hold a number of important managerial and policy implications regarding technological adoption, specialization, and the quality of interaction among ICU team members. They suggest intervention "leverage points" for care givers, managers, and external policy makers in efforts to continuously improve the outcomes of intensive care.
