Drug use among functionally active, aged, ambulatory people.

Area of Science:

• Gerontology
• Pharmacoepidemiology
• Geriatric Medicine

Background:

• Limited pharmacoepidemiology research includes very old subjects, often mixing healthy and ill individuals.
• Interpretation of drug use in the elderly is challenging due to heterogeneous health statuses.
• Previous studies often included mixed populations, limiting insights into drug use among healthy, active very old individuals.

Purpose of the Study:

• To examine drug utilization patterns in a cohort of active, relatively healthy, very old individuals.
• To assess the prevalence of adverse drug effects in this specific demographic.
• To investigate the relationship between drug use and health status, including falls, in the elderly.

Main Methods:

• A study population of 61 volunteers aged 76-96 years attending a national convention.
• Data collection included medication histories (prescription and non-prescription), blood biochemistry, and mental status examinations.
• Focus on ambulatory, relatively healthy, and functional very old participants.

Main Results:

• The average use was 2.02 prescription and 1.85 non-prescription drugs per person.
• Over 25% used no prescription drugs; two-thirds used two or fewer.
• 16% of those on prescription medications reported adverse effects; falling prevalence did not correlate with drug use patterns.

Conclusions:

• Very old, healthy, and functional individuals do not necessarily exhibit excessive drug use.
• Adverse drug effects remain a concern even in this population.
• Advanced age alone does not invariably lead to sickness, frailty, or polypharmacy.
