Aim of the review: Use of smart devices to provide real-time cardiopulmonary resuscitation (CPR) feedback in the context of out-of-hospital cardiac arrest (OHCA) has considerable potential for improving survival. However, the findings of previous studies evaluating the effectiveness of these devices have been conflicting. Therefore, we conducted a systematic review of the literature to assess the utility of smart devices for improving the quality of CPR during CPR training.Data sources: Thirteen electronic databases were searched. The articles were reviewed according to the eligibility criteria. CPR quality was evaluated based on the rates and depths of chest compression, and the proportion of adequate depth of chest compressions.Results: Ultimately, 11 studies (5 randomised controlled trials, 1 randomised trial, and 5 randomised cross-over trials) were selected for this systematic review. Eight of these studies used smartphones and three used smartwatches. This review did not find an apparent benefit from smart device use during CPR in terms of maintaining the recommended compression rates and depths of chest compressions. However, all three smartwatch studies reported that the proportion of chest compressions of adequate depth was significantly improved with smartwatch use (smartwatch group vs. nonsmartwatch group in the three studies: 65.01% vs. 45.15%, p = 0.01; 64.6% vs. 43.1%, p = 0.049; 98.7% vs. 79.3%, p = 0.002).Conclusion: This review does not find durable evidence for usefulness of smart devices in CPR training. However, the smartwatches may improve the accuracy of chest compression depth. Future studies with larger sample sizes might be necessary before reaching a firm conclusion.
Background Psychiatric triage algorithm can improve the quality of care by providing a systematic method for classifying the severity of patients experiencing psychiatric crisis in the emergency room and by determining the optimal time frame for intervention. The aim of the present study was to test the professional validity and clinical validity of a psychiatric triage algorithm developed for use in South Korea.Methods The initial algorithm was developed through systematic literature review. Its validity was then verified by 10 experts. Based on results of expert validity, the algorithm was modified and the final algorithm was developed.Results Its clinical validity was then verified by 30 emergency room nurses who had used triage. Four questions of expert validity results with a CVI of 0.8 or less were revised to reflect expert opinion. The clinical validity of the final modified algorithm was 2.9 ~ 3.47.Conclusion The use of highly validity psychiatric triage algorithm by ER (Emergency Room) nurses not only can improve the quality of care, but also can improve patient outcomes and experience.
Background Psychiatric emergencies require timely intervention because of the risk of harm to individuals and society, including others. The aim of the present study was to test the content validity of a psychiatric triage algorithm developed for use in South Korea. Methods The initial algorithm was developed through systematic literature review. Its validity was then verified by 10 experts. Based on results of expert validity, the algorithm was modified and the final algorithm was developed. Results Its clinical validity was then verified by 37 emergency room nurses who had used triage. Four questions of expert validity results with a CVI of 0.8 or less were revised to reflect expert opinion. The usefulness, adequacy, and convenience of the final modified algorithm was 2.98 ~ 3.53. Conclusion After sufficiently validated by follow-up studies, it is expected that the use of psychiatric classification algorithms in emergency room nurses will not only improve the quality of care, but also can improve patient outcomes and experience.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
