Postoperative Ketorolac in Breast and Body Contouring Procedures: A Nationwide Claims Analysis.

ABSTRACT: BACKGROUND:Nonsteroidal antiinflammatory drugs are useful alternatives to narcotics for analgesia. However, concerns remain regarding their safety. The authors evaluated ketorolac use and complications. We hypothesized that no association between ketorolac and morbidity exists in patients undergoing body contouring. METHODS:Truven MarketScan claims database was analyzed for patients undergoing breast and body contouring surgery. Patients selected received ketorolac and were enrolled a minimum of 90 days. The authors performed a multivariable logistic regression to calculate risk of morbidity, adjusting for clinical and sociodemographic factors. RESULTS:Among the 106,279 patients enrolled, 4924 (4.6 percent) received postoperative ketorolac. In multivariable regression analysis, ketorolac was not associated with hematoma (OR, 1.20; 95 percent CI, 0.99 to 1.46; p > 0.05). There was an increased rate of reoperation within 72 hours (OR, 1.22; 95 percent CI, 1.00 to 1.49; p < 0.05; number needed to harm, 262 patients). Ketorolac was associated with fewer readmissions (OR, 0.76; 95 percent CI, 0.62 to 0.93; p < 0.05; number needed to treat, 87 patients), with a reduction in the rate of pain as a readmission diagnosis (0.6 percent versus 4.3 percent; p = 0.021). Ketorolac was associated with seroma, but this association may not be causal (OR, 1.28; 95 percent CI, 1.05 to 1.57; p < 0.05; number needed to harm, 247 patients). Ketorolac provided an estimated savings of $157 per patient. CONCLUSIONS:The benefits of ketorolac likely outweigh the risks after surgery. Absolute differences in reoperation rates were low, and improved rates of hospital admission impact cost savings. The authors advocate postoperative ketorolac once the wound is hemostatic. CLINICAL QUESTION/LEVEL OF EVIDENCE:Therapeutic, III.

Project description:PurposeTo develop a new approach for interobserver variability analysis.Methods and materialsEight radiation oncologists specializing in breast cancer radiation therapy delineated a patient's left breast "from scratch" and from a template that was generated using deformable image registration. Three of the radiation oncologists had previously received training in Radiation Therapy Oncology Group consensus contouring for breast cancer atlas. The simultaneous truth and performance level estimation algorithm was applied to the 8 contours delineated "from scratch" to produce a group consensus contour. Individual Jaccard scores were fitted to a beta distribution model. We also applied this analysis to 2 or more patients, which were contoured by 9 breast radiation oncologists from 8 institutions.ResultsThe beta distribution model had a mean of 86.2%, standard deviation (SD) of ±5.9%, a skewness of -0.7, and excess kurtosis of 0.55, exemplifying broad interobserver variability. The 3 RTOG-trained physicians had higher agreement scores than average, indicating that their contours were close to the group consensus contour. One physician had high sensitivity but lower specificity than the others, which implies that this physician tended to contour a structure larger than those of the others. Two other physicians had low sensitivity but specificity similar to the others, which implies that they tended to contour a structure smaller than the others. With this information, they could adjust their contouring practice to be more consistent with others if desired. When contouring from the template, the beta distribution model had a mean of 92.3%, SD ± 3.4%, skewness of -0.79, and excess kurtosis of 0.83, which indicated a much better consistency among individual contours. Similar results were obtained for the analysis of 2 additional patients.ConclusionsThe proposed statistical approach was able to measure interobserver variability quantitatively and to identify individuals who tended to contour differently from the others. The information could be useful as feedback to improve contouring consistency.
