Examining the response times and patterns of care of paramedics in Mississippi, Dr. Brachet and his co-authors documented that performance during emergencies deteriorates toward the end of long shifts, with potentially fatal consequences. Their findings highlight a critical point: in certain contexts, longer hours can affect the quality of care and endanger lives.
