Program director longevity in emergency medicine residencies: A 40-year analysis.

Objective: We sought to assess trends in emergency medicine residency program director (PD) length of service over the past 40 years and evaluate relationships between duration of service and important factors such as PD start year, geographic region, and year of program initial accreditation.

Methods: We retrospectively analyzed program data from the American Medical Association Graduate Medical Education Directory and Emergency Medicine Residents' Association Match database. We calculated descriptive statistics and used linear regression to assess the impact of PD start year, region, and year of program initial accreditation on PD duration of service.

Duration of cardiopulmonary resuscitation and phenotype of post-cardiac arrest brain injury.

Background: Patients resuscitated from cardiac arrest have variable severity of primary hypoxic ischemic brain injury (HIBI). Signatures of primary HIBI on brain imaging and electroencephalography (EEG) include diffuse cerebral edema and burst suppression with identical bursts (BSIB). We hypothesize distinct phenotypes of primary HIBI are associated with increasing cardiopulmonary resuscitation (CPR) duration.

Precision of time devices used by prehospital providers.

Background: As many medical, medicolegal, and research interests have become more time-dependent, increased weight should be placed on the precision of time documentation and timing devices. Studies have previously documented poor synchronization of timing devices in the medical setting. Objective.
