Estimates of time intervals by bystanders are considered critical in cardiac arrest, and are often used in other disorders such as stroke and myocardial infarction. Because they have never been previously studied, we sought to determine their accuracy. ⋯ Although many diagnostic and research conclusions are based on interval estimates from laypersons, we found no correlation between estimates and actual measured intervals in cardiac arrest. Current methodology may not be developed well enough to provide reliable data for research or quality assurance, and other clinical time estimates by patients and bystanders may be equally unreliable.
