Rescuer factors predict high-quality CPR-a manikin-based study of health care providers

Background: In the provision of high-quality cardiopulmonary resuscitation (CPR) by health care providers, factors associated with high-quality CPR should be explored. Methods: This is a post hoc analysis using data from a manikin-based survey of CPR quality among volunteer emergency medical technicians (EMTs) from 2 county fire departments in northern Taiwan. Results: Among the 95 enrolled EMTs, 36 (37.9%) performed high-quality CPR on a manikin. The baseline characteristics that differed significantly between groups were board-certified EMT levels (P = .010), body mass index (BMI, P - .029), average exercise frequency (P - .001), and average exercise duration (P - .005). Average total exercise time per week, which uses frequency times exercise duration, was independently associated with high-quality CPR performance after adjusting for variables via logistic regression analysis (odds ratio, 1.004; P = .044). An index was developed (BMI x ExeTime) based on the product of BMI and average total exercise time per week. A comparison of the area under curve for the different indices showed that BMI x ExeTime was a significant predictor of high-quality CPR, with an area under curve of 0.718 (95% confidence interval, 0.613-0.824; P < .001; Fig. 2) and a cutoff value of 4136.7 kg.min/m(2) (sensitivity, 0.722; specificity, 0.678). Conclusions: This study identified factors associated with the performance by health care providers of high-quality CPR, including BMI and exercise habits. To optimize CPR quality, a program of exercise frequency and duration adjusted according to individual's BMI should be considered in such populations. (C) 2015 Elsevier Inc. All rights reserved.
