Development of the Post-General Anesthesia Respiratory Complication Risk Assessment Form
Keywords:

This research and development study aimed to develop a risk assessment form for post-general anesthesia respiratory complications (P-GARCs). A total of 322 patients were selected for the study using a consecutive purposive sampling method. The study was carried out in three phases including 1) assessment form development, 2) assessment form accuracy evaluation and 3) implementation of assessment form in clinical practice. Descriptive statistics were used to summarize data and Cox proportional hazard regression was used to identify P-GARCs risk factors. Receiver operating characteristic (ROC) curve was used to illustrate diagnostic ability of the form.
Results revealed that the P-GARCs risk assessment form (PRAF) consisted of 11 items with a total score of 30 points. PRAF assesses P-GARCs risk in 2 categories; 1) patient factors including age, sex, anesthetic health status, underlying respiratory diseases, oxygen saturation level, and smoking status and (2) healthcare factors including operation site, types of operation, duration of intubation, and number of intubations. PRAF had a content validity index of 0.87 and inter-rater reliability of 0.81. In assessing P-GARCs risk, at the cut-off of 13 points PRAF had a sensitivity of 96.9%, specificity of 85.2%, and the area under curve (AUC) of 0.73 (95%CI 0.64-0.82, p < .001). Results indicated that PRAF is effective in assessing the risk for P-GARCs and can be used to screen at-risk patients and plan for proper management to prevent P-GARCs after the operation.
