This pilot study shows a geriatric medication algorithm helped reduce inappropriate prescribing in older adults. The algorithm assisted resident physicians in optimizing medication regimens for patients over 65.

Area of Science:

  • Geriatrics
  • Pharmacology
  • Clinical Pharmacy

Background:

  • Inappropriate prescribing is a significant issue in geriatric patients, leading to adverse drug events.
  • Polypharmacy in older adults increases the risk of medication-related problems.

Purpose of the Study:

  • To evaluate the effectiveness of a geriatric medication algorithm in reducing inappropriate prescribing.
  • To assess changes in medication regimens among elderly outpatients.

Main Methods:

  • A geriatric medication algorithm was implemented in a resident outpatient clinic.
  • Medications of 41 patients aged over 65 taking more than three drugs were compared pre- and post-algorithm.
  • Paired t-test was used for statistical analysis.

Main Results:

  • The average number of drugs per patient decreased from 5.8 to 5.6.
  • Fifteen high-risk medications were discontinued, and seven were substituted for less toxic alternatives.
  • The algorithm demonstrated a statistically significant reduction in inappropriate prescribing (p < 0.025).

Conclusions:

  • The geriatric medication algorithm is effective in assisting resident physicians to reduce inappropriate prescribing in older adults.
  • The algorithm facilitates the discontinuation of high-risk medications and substitution with safer alternatives.
