Decision curve analysis demonstrated that the nomogram was clinically useful. This study proposed an effective nomogram with potentially application in facilitating the individualized prediction for extended operation time. Individualized prediction of prolonged operation time can be conveniently facilitating an adequate treatment plan management and postoperative prevention.

Suboptimal cancer pain management is a worldwide problem. We examined whether an educational program on cancer pain management implemented during training could benefit primary care physicians. We enrolled all the primary care physicians who visited the oncology ward at a medical center for the first time. Educational classes on cancer pain management were conducted. The participants' abilities in cancer pain management were measured in a pretest before the classes and approximately 2weeks later in the first posttest. The second posttest was conducted on participants who visited the oncology ward again. All 3 tests had the same set of questions and were scored on a scale of 0 to 100. In total, 247 participants were enrolled. Less than 10% of them considered their previous education on cancer pain management adequate. The test scores increased significantly from the pretest to the first posttest (mean 65.6 vs. 89.7, p < 0.001). The participants' self-reported cancer pain management abilities, on a scale of 0 to 100, also improved significantly (mean 57.8 vs. 75.5, p < 0.001). The pretest scores were not associated with the participants' self-reported abilities or their perceptions about the adequacy of previous training on cancer pain management. The mean score on the second posttest, conducted 234.5days after the prog
