Abstract
STUDY OBJECTIVE: We endeavor to assess the impact of introduction of guidelines for preoperative investigations (PIs) on anesthetic practices and costs and compare their efficacy to current practices. DESIGN: A prospective study. SETTING: Queen Elizabeth Hospital, Barbados. PATIENTS: Participants comprised all patients undergoing general, epidural, spinal, and regional anesthesia, with the exception of emergency cases or instances where an anesthesiologist was not required. INTERVENTION: Introduction of formal guidelines for preoperative investigations. MEASUREMENTS: The patterns of preoperative testing were assessed by audit, and this assessment was repeated postintervention. PI guidelines developed were presented to all surgical departments. MAIN RESULTS: For younger patients (<60 years), the mean number of tests decreased from 3.42±1.8 in the preguideline group to 2.89±1.98 in the postguideline group (P=.042). The total number of chest x-rays decreased by 14.8% (P=.012) and full blood counts by 7.6% (P=.036). The implementation of PI guidelines led to overall savings of US $7589 per 1000 patients, which is equivalent to (US $40,745.50 per annum). The most notable savings were due to decreased number of chest x-rays. PIs were performed routinely even in the absence of clinical indications. CONCLUSION: Our findings indicate that introduction of guidelines has reduced the level of preanesthetic investigations to some extent; nevertheless, further change is desirable. In addition, costs to the institution were decreased with no compromise to patient safety.
