    Abstract:
    OBJECTIVE: Assessing timing efficacy of anesthetic evaluation in pediatric day-surgery by a diagnostic accuracy study. AIM: Lowering hospital visits in patients with negative medical history. BACKGROUND: Pediatric patients scheduled for day-surgery procedures can be categorized, according to their history, in two groups. One, the largest, includes healthy patients and the other includes those with medical conditions that necessitate further evaluation. MATERIALS AND METHODS: Clinical data are collected by the pediatric surgeons of our department and reviewed by an anesthetist who then selects the timing of anesthesiology evaluation, which will take place in the same day of the procedure (One-Stop Anesthesia), or some days before it, in a dedicated setting (Pre-Admission Clinic). In 2008, 332 children, older than 12 months, screened by that method, underwent surgical procedures in general anesthesia. RESULTS: Our data were examined using Bayesian Statistical Analysis. In the 'One-Stop Anesthesia' group, true positive were 290 (87.4%) and false positive 4 (1.2%). Of the 38 patients assessed by our Pre-Admission Clinic, true negative were 30 (9%) and false negative 8 (2.4%). Sensibility (97.3%), specificity (88.2%), positive predictive value (98.6%), negative predictive value (78.9%), diagnostic accuracy (96.4%), likelihood positive (8.3), and likelihood negative (0.03) were calculated. CONCLUSIONS: Timing the preoperative anesthesiologist's evaluation avoided 88% of hospital visits, usually to the Pre-Admission Clinic, and thus, it was cost effective, reducing direct and indirect costs of healthcare providers.
