Clinical Report: Analysis of Risk Factors Associated with PIM Use

Overview

This study identifies key risk factors for potentially inappropriate medication (PIM) use among older adults, highlighting the significant roles of age and healthcare utilization patterns.

Background

Polypharmacy is increasingly common among older adults and is linked to adverse drug events and increased mortality. Identifying risk factors for PIM use is crucial for improving medication safety in this population. The American Geriatrics Society Beers Criteria serve as a guideline for identifying PIMs, yet the relationship between healthcare utilization and PIM use remains underexplored.

Data Highlights

ParameterValue
Mean Age72.3 ± 17.5 years
Correlation of Age with Medicationsr = 0.476; p < 0.0001
Common PIMProton pump inhibitors
Patients with PIMsConsulted more medical facilities

Key Findings

  • Age positively correlates with the number of prescribed medications.
  • Proton pump inhibitors were identified as the most common PIMs.
  • Patients prescribed ≥1 PIM consulted significantly more medical facilities.
  • Independent risk factors for PIM use include age, hypertension, gastrointestinal disorders, and neuropsychiatric disorders (excluding dementia).
  • Fragmented healthcare utilization is associated with increased PIM prescriptions.

Clinical Implications

Healthcare providers should be aware of the increased risk of PIM use in older adults, particularly those with multiple comorbidities and those consulting multiple medical facilities.

Conclusion

The study identifies a significant association between advanced age, fragmented healthcare utilization, and PIM prescriptions.
