Accuracy of Healthcare Providers' Perception of Chest Compression Depth and Chest Recoil

Abstract

Objective: The objective of this paper was to evaluate the validity and accuracy of healthcare providers' perception of chest compression depth and chest recoil during cardiopulmonary resuscitation (CPR). Methods: A clinical simulation study was performed with healthcare providers trained in CPR including physicians, nurses, and Emergency Medical Technicians (EMI). Following 2 minutes of hands-only-CPR on a sensor-programmed manikin, providers were able to respond to subjective questions assessing their adequacy of CPR. The providers' perception contrasted with the objective data obtained from the manikin. The validity and accuracy of CPR providers' perception of chest compression depth and chest recoil was assessed by the calculation of sensitivity, specificity and predictive values. Results: 180 Advanced or basic life support certified healthcare providers were enrolled. The degree of correlation between self-perception and actual performance was 52.2% in the thoracic compression depth and 61.7% in tic chest recoil. Caregivers' perception of chest compression depth had a sensitivity of 29.4% and a specificity of 87.3%. Caregivers' perception of chest recoil had a sensitivity of 30.3% and a specificity of 79.8%. Conclusions: Healthcare providers' perception for evaluating the accuracy of thoracic compressions is not as accurate as objective feedback methods during CPR This may impact patient outcomes during a cardiac arrest.
