Effects of practice on competency in single-rescuer cardiopulmonary resuscitation.

Acknowledgment: The project was coordinated through the National League for Nursing (NLN). Conflict of Interest Statement: The authors acknowledge the following potential conflict of interest: Laerdal Medical Corporation and the AHA supplied the materials and equipment for the study at no cost to the schools of nursing that served as training sites. Representatives from the NLN, Laerdal Medical Corporation, and the AHA served on the team with the investigators that designed the study. The NLN, Laerdal Medical Corporation, and AHA were not involved in the collection, analysis, and interpretation of data; in the writing of the manuscript; nor in the decision to submit the manuscript for publication. The investigators and site coordinators had sole responsibility for implementing the study and collecting and uploading the data. The investigators had sole responsibility for data analysis and interpretation, and for writing and submitting the manuscript. There were no restrictions by the NLN, Laerdal Medical Corporation, or the AHA on the statistical analysis or publication of the findings. C ardiac arrests remain a significant health problem and leading cause of death both in and out of hospitals. Regardless of the setting, prompt initiation of quality cardiopulmonary resuscitation (CPR) improves patient sur-other health care providers, and laypersons need to be trained effectively to develop and retain their CPR skills. This requires using or practicing skills frequently to avoid rapid decline.
