Timely identification of elderly patients who are at risk of developing intraoperative hypothermia (IH) is imperative to enable appropriate interventions. This study aimed to develop a nomogram for predicting the risk of IH in elderly patients undergoing resection of craniocerebral tumor, and to validate its effectiveness. Elderly patients who underwent craniocerebral tumor resection at a large tertiary hospital in eastern China between January 2019 and December 2022 were included (n = 988). The study population was divided into a training set and a validation set by time period. Risk factors identified through the Least Absolute Shrinkage and Selection Operator method and logistic regression analysis were used to establish the nomogram. The model was validated internally by Bootstrap method and externally by validation set through receiver operating characteristic curve analysis, Hosmer-Lemeshow test, and decision curve analysis. A total of 273 (27.6%) patients developed IH. Duration of anesthesia (P < 0.001), blood loss (P < 0.001), preoperative temperature (P < 0.001), tumor location (P < 0.001), age (P < 0.05), and mean arterial pressure (P < 0.05) were identified as independent risk factors for IH. A nomogram integrating these 6 factors was constructed. The area under the curve was 0.773 (95% confidence interval: 0.735–0.811) (70.5% specificity and 75.0% sensitivity), indicating good predictive performance. The decision curve analysis demonstrated the clinical benefit of using the nomogram. Our model showed good performance in identifying elderly patients who are at high risk of developing IH during craniocerebral tumor resection. The nomogram can help inform timely preventive interventions. [ABSTRACT FROM AUTHOR]

Background: Incorrect surgical counts are closely related to retained surgical items, which pose a threat to patients. However, the risk factors for incorrect surgical counts have not been identified yet. Aim: To identify the risk factors associated with incorrect surgical counts during surgery in a tertiary hospital. Design An observational case–control study. Methods: Seventy cases of incorrect surgical counts were reviewed in this study. Data were collected from January 1, 2014, to April 4, 2019. For each case, we included four randomly selected control cases involving the same surgical procedures by the same surgeon within a 6‐month period for comparison. The medical data of these cases were extracted for further statistical analysis. Results: A higher incidence of incorrect surgical counts was observed among surgical counts performed between 8:00 a.m. to 12:00 a.m., emergency operations, prolonged procedures, and/or after addition of surgical items. Conclusion: Prolonged surgical procedures, emergency operations, time of occurrence, and addition of surgical items were the risk factors related to incorrect surgical counts during surgery. Summary statement: What is already known about the topic? Incorrect surgical count is a perplexing problem during operation.Incorrect surgical count is closely associated with retained surgical items which can cause patient injury.The underlaying risk factors of incorrect surgical count were still unknown. What this paper adds? This was the first case–control study for incorrect surgical counts in China.The present research demonstrated that several risk factors were significantly associated with the occurrence of incorrect surgical counts, including the time period, the type of surgery, and the duration of the procedure.Vigilance should be maintained during an emergency operation or a long procedure to reduce the incidence of incorrect surgical counts. The implications of this paper: It is important for nurses to be aware of the factors that can interfere with correct surgical counts, thereby ensuring vigilance during emergency operations or long procedures.By identifying these risk factors, a more comprehensive safety policy in the operation room can be implemented to reduce incorrect surgical counts.Novel technological adjuncts should be promoted in the operating room gradually to improve overall patient safety.
