Area of Science:

  • Geriatric Medicine
  • Pharmacology
  • Public Health

Background:

  • The elderly population is vulnerable to adverse drug events due to physiological changes.
  • Inappropriate medication prescribing in older adults is a persistent issue in healthcare.
  • Assessing the prevalence of such prescriptions is vital for quality improvement initiatives.

Purpose of the Study:

  • To determine the frequency of inappropriate medications prescribed to patients aged 65 and older by office-based physicians.
  • To identify specific medications commonly and rarely prescribed inappropriately to the elderly.

Main Methods:

  • Utilized data from the National Ambulatory Medical Care Survey (NAMCS) in 1992, a nationwide cross-sectional survey.
  • Analyzed office visits by patients 65 years or older, focusing on prescriptions of 20 medications deemed inappropriate for the elderly.

  • Employed criteria established by a panel of geriatric medicine and pharmacology experts.
  • Main Results:

    • An estimated 8.47 million office visits by the elderly in 1992 involved at least one of the 20 inappropriate medications.
    • Approximately 7.58% of elderly patients receiving prescriptions were prescribed at least one inappropriate medication.
    • Propoxyphene, amitriptyline, dipyridamole, diazepam, and chlorpropamide were the most frequently prescribed inappropriate drugs.

    Conclusions:

    • The high prevalence of inappropriate medication prescribing for older adults in ambulatory settings is a significant concern for care quality.
    • Improving the care of elderly patients necessitates enhanced collaboration between physicians and pharmacists.
    • Targeted interventions and education are needed to reduce the prescribing of harmful medications to seniors.
