Medication errors are common in healthcare and can cause harm or death. A study identified 571 medication errors in 390 patients over 6 months at a tertiary care hospital. The most common errors were prescribing errors (71%), followed by administration errors (26%) and dispensing errors (3%). The majority of errors were caused by clinicians (49%), nurses (24%), and pharmacists (15%). Common types of errors included wrong dose, frequency, and drug omission. Most errors were classified as causing no harm. The study recommends strategies like systematic documentation, generic prescribing, treatment chart review, and drug utilization evaluation to prevent common medication errors in the hospital.
