AbstractThis study determined whether the Simplified Postoperative Nausea and Vomiting Impact Scale (SPONVIS), could be used to predict clinically important PONV in Taiwanese. In this prospective, observational study, SPONVIS, simplified Apfel PONV Risk Scores, post-operative anti-emetic drug use, total PONV score, and 3-month recall score for PONV were recorded from Taiwanese patients who had undergone general anesthesia and surgery. With antiemetic use and 3-month recall score as validations of clinical significance, we determined whether the elements and cut-off points used in the original SPONVIS study could be used in Taiwanese patients. A total of 378 patients were included in the analysis. One hundred forty (37.1%) patients had PONV. Forty-eight patients (12.7%) had clinically important PONV (SPONVIS score ≥ 5). The odds ratios were 14.26 (CI 6.91-29.43; P < 0.001) and 4.95 (CI 2.42 to 10.11; P < 0.001), respectively, for prediction of anti-emetic drug use and 3-month recall. The SPONVIS and its construct elements were significantly related to anti-emetic drug use, 3-month recall score for PONV, total PONV score, and Apfel risk score (all P ≤ 0.005), results similar to those reported in the original Australian PONV impact score study. The SPONVIS cut-off points 3 and 5 were statistically significant predictors of anti-emetic drug use. However, a cut-off point of 3 had a higher OR (24.08) than a cut-off of 5 (14.26) for prediction of anti-emetic drug use. SPONVIS and both construct elements (the nausea and vomiting impact scores) are useful predictors of clinically important PONV in Taiwanese.
