Factors related to errors in medication prescribing

Area of Science:

• Medical Informatics
• Clinical Pharmacy
• Patient Safety

Background:

• Medication prescribing errors pose a significant risk to patient safety.
• Identifying the root causes of these errors is crucial for developing effective prevention strategies.

Purpose of the Study:

• To systematically identify and quantify the types and frequency of factors contributing to medication prescribing errors.
• To assess the potential for adverse patient outcomes associated with these errors.

Main Methods:

• A systematic evaluation of every third prescribing error with potential clinical importance was conducted over one year in a tertiary care teaching hospital.
• Errors were concurrently assessed for potential adverse consequences and retrospectively analyzed by physicians and pharmacists to identify related factors.

Main Results:

• A total of 696 errors with potential for adverse effects were analyzed.
• The most frequent specific factors included altered renal/hepatic function (13.9%), patient allergy history (12.1%), incorrect drug nomenclature (11.4%), dosage calculation errors (11.1%), and atypical dosage frequencies (10.8%).
• Common contributing factor groups were related to knowledge of drug therapy (30%), patient factors affecting drug therapy (29.2%), calculation/expression errors (17.5%), and nomenclature issues (13.4%).

Conclusions:

• Numerous identifiable factors are linked to a substantial proportion of medication prescribing errors.
• Targeting educational, technological, and risk management efforts on these common factors can mitigate patient risk from adverse drug events.
