Impact of personal protective equipment on the effectiveness of chest compression - A systematic review and meta-analysis

Background and objectives: To assess the impact of personal protective equipment (PPE) on different aspects of chest compression (CC) during cardiopulmonary resuscitation, we conducted this study. Methods: This systematic review was performed according to the PRISMA. We searched PubMed, EMBASE and Web of Science from inception to June-6, 2020, limiting to the studies that reported the comparison of the effectiveness of CC in terms of CC rate, CC depth, the proportion of adequate CC rate, the proportion of adequate CC depth or proportion of adequate recoil; in study arms with or without PPE. Risk of bias was assessed by the ROB-2 and ROBINS-I tool. Quantitative data synthesis was done using the generic inverse variance method and the fixed-effects model. Results: Five simulation-based studies were finally included. A Significant decrease in CC rate (SMD: -0.28, 95%CI: -0.47 to -0.10) and CC depth (SMD: -0.26, 95%CI: -0.44 to -0.07) were observed in the PPE arm as compared to the no-PPE arm. The difference in CC rate was more prominently seen in adult CPR than in paediatric CPR. Without PPE, the proportion of adequate CC rate delivered was 0.74, which reduced significantly to 0.60 after use of PPE (p - 0.035). Similarly, the proportion of adequate CC depth was significantly lesser (p - 0.001) in PPE arm (0.55), as compared to that of the no-PPE arm (0.78). Conclusion: The use of PPE compromises the quality of CC during CPR significantly, and newer ways to deliver chest compression has to be investigated. (C) 2020 Elsevier Inc. All rights reserved.

Automated summary

This study assessed the impact of personal protective equipment (PPE) on chest compressions during CPR, showing a significant decrease in CC rate and depth with the use of PPE. The proportion of adequate CC rate and depth were also significantly reduced in the PPE arm compared to the no-PPE arm. Newer ways to deliver chest compression need to be explored to maintain quality CPR.
