RESUMO
PURPOSE: To determine the risk of unanticipated intraoperative events (UIE) in patients assessed at a preanaesthetic clinic compared with those not assessed at the clinic. METHODS: Preoperative and intraoperative data were collected on 6130 elective surgical patients by procedural anaesthetists over a 12-month-period at an Australian tertiary referral hospital. The procedural anaesthetists rated the level of preparation and identified predefined unanticipated intraoperative events. A logistic regression model was used to identify significant risk factors of UIE and was further validated on another sample of 482 patients (one month) by a goodness-of-fit test. RESULTS: Of the 6130 elective surgical patients, 2000 (33%) had been assessed at the preanaesthetic clinic. There was a greater proportion of ASA II to IV patients seen at the clinic than patients not assessed at the clinic (chi 2(3) = 689.92, P < 0.001). Nonclinic patients were more likely to be inadequately prepared than clinic patients (RRunadjusted = 1.61, 95% CI: 1.25 to 2.04, P < 0.001). The overall incidence of intraoperative events was 4.14% (95% CI: 3.64% to 4.64%). Despite adjusting for the preparation level, type of anaesthesia, admission category, ASA physical status and duration of anaesthesia, clinic patients were 1.94 (95% CI: 1.42 to 2.64) times more likely to experience an UIE than nonclinic patients (P < 0.001). CONCLUSION: Although clinic patients were more often optimally prepared, their adjusted risk of UIE was higher than nonclinic patients. The procedural anaesthetist needs to be vigilant with these high risk patients, even if they have been assessed at a preanaesthetic clinic.

OBJECTIVES: To evaluate the training of clinical staff in the use of interhospital transfer guidelines and to examine the underlying decision-making behavior in organizing patient transfers between hospitals. DESIGN: Prospective assessment of clinical scenarios, given before (time 1), immediately after (time 2), and 3 months after (time 3) a program informing clinical staff about the use of interhospital transfer guidelines. SETTING: Three emergency departments and one intensive care unit at three hospitals and a medical retrieval service in Sydney, Australia. SUBJECTS: Physicians, nurses, and a paramedic working in critical care areas and at a medical retrieval service. MEASUREMENTS AND MAIN RESULTS: A questionnaire containing clinical scenarios was administered to clinical staff. There was a significant difference in mean scores for selecting the appropriate escort levels across time (F2,78 = 24.2; p < .01) and for participant's experience with interhospital transfer (F2,39 = 4.63; p = .02). Significant improvement in mean scores occurred between time 1 (7.55 +/- 1.84 and time 2 (9.48 +/- 1.47) (t41 = -6.21; p < .01). The improvement in selecting appropriate escorts was maintained at time 3 (mean score 9.86 +/- 2.01). The error rate for inappropriate assignment of low levels of escorts decreased from 35% (time 1) to 10% (time 2) and 14% (time 3). Using conjoint analysis, there were large variations in the decision-making behaviour between each time period. The relative importance of each factor in influencing the decision to organize an escort at time 3 were as follows: treatment (43%); physiology (29%); patient age (24%); and diagnosis (4%). The decision-making model observed at time 3 had a high predictive value (87%) as compared with the model at time 1 (48%). CONCLUSION: Clinical staff can make informed and appropriate decisions by using standardized guidelines when organizing interhospital transfers.

A Perioperative Service has recently been introduced at liverpool hospital, a 460-bed university teaching hospital. This provides a co-ordinated system for managing all elective surgical patients from the time an admission booked until hospital discharge. This paper describes the patient assessment, structure and staff requirements, benefits of and problems encountered with this service. The patient's preoperative preparation occurs before hospital admission. Where possible, patients are admitted on the day of procedure, either as a day-only patient, or a day-of-surgery patient. Patients are initially admitted to a specifically designed Perioperative Unit, adjacent to the Operating Theatre Suite. Patients do not enter the surgical wards until after their operation. Planning of the hospital discharge process commences at the time of booking for operation. Introduction of the Perioperative Service was staged process commencing in mid-1992. The hospital admits approximately 6,400 elective surgery cases each year. From July 1992 to December 1994, day-only patients were approximately 45% of these cases. Day-of surgery admission patients increased from 6% to 35% of all cases over the same period. Approximately 22% of elective surgical cases were seen in the Perioperative Clinic. As the Perioperative Service became fully operational, the average length of stay for elective surgical procedures fell. There has been a reduction in the areas of cancellations due to unavailability of beds, inappropriate preparation of patients, and non-attendance of patients for booked procedures. Patient acceptance is high. The existence of a perioperative system facilitates the planning and management of elective surgery with maximum quality and efficiency.
