title: Value of preoperative clinic visits in identifying issues with potential impact on operating room efficiency.
abstract: BACKGROUND
  Preoperative clinics have been shown to decrease operating room delays and cancellations. One mechanism for this positive economic impact is that medical issues are appropriately identified and necessary information is obtained, so that knowledge of the patients' status is complete before the day of surgery. In this study, the authors describe the identification and management of medical issues in the preoperative clinic.
  
  
  METHODS
  All patients coming to the Preoperative Clinic during a 3-month period from November 1, 2003, through January 31, 2004, at the Brigham and Women's Hospital, Boston, Massachusetts, were studied. Data were collected as to the type of issue, information needed to resolve the issue, time to retrieve the information, cancellation and delay rates, and the effect on management.
  
  
  RESULTS
  A total of 5,083 patients were seen in the preoperative clinic over the three-month period. A total of 647 patients had a total of 680 medical issues requiring further information or management. Of these issues, 565 were thought to require further information regarding known medical problems, and 115 were new medical problems first identified in the clinic. Most of the new problems required that a new test or consultation be done, whereas most of the old problems required retrieval of information existing from outside medical centers. New problems had a far greater probability of delay (10.7%) or cancellation (6.8%) than old problems (0.6% and 1.8%, respectively).
  
  
  CONCLUSIONS
  The preoperative evaluation can identify and resolve a number of medical issues that can impact efficient operating room resource use.
