The importance of intra-hospital pharmacovigilance in the detection of medication errors

Area of Science:

• Pharmacovigilance
• Patient Safety
• Healthcare Quality

Background:

• Hospitalized patients face significant risks from medication errors, a leading cause of death.
• Intra-hospital pharmacovigilance departments play a crucial role in preventing and managing medication-related harm.

Purpose of the Study:

• To analyze medication errors reported by a Mexican pharmacovigilance system.
• To assess the impact of these medication errors on patient outcomes.

Main Methods:

• A prospective study was conducted from 2012 to 2015.
• Medication prescriptions for 56,368 patients (292,932 prescriptions) were analyzed.
• Data heterogeneity was managed using absolute numbers on a logarithmic scale.

Main Results:

• 8.9% of medication errors were identified.
• Treating physicians were responsible for the majority of errors (83.32%).
• No medication errors resulted in permanent damage or death.

Conclusions:

• This study represents the largest sample size reported for a pharmacovigilance analysis of medication errors.
• Effective pharmacovigilance systems are essential for identifying and mitigating medication errors in hospitals.
