4. Epidemiology
• Interesting but horrifyingfact-
•-More people in USAdie in agiven year asa
result of medicalerrors than from motor
vehicle accidents,breast cancers,or AIDS
• Numbers reported canbe lessdueto-
Small%of errors & adverse drug events
detected, even smaller number arereported
Most studies have looked errors only in inpatient
settings
5. Causes of Errors
• Overload/Weekends
• Too many patients
• Lack of Concentration
• Double check not possible
• Shortage of staff
• Illegible Prescription
