- Design
- Repeated cross-sectional national survey analysis, 1999–2020
- Population
- 12,766 community-dwelling US adults ≥65
- Primary outcome
- Mean prescription count by frailty level
- Effect
- Moderate–severe frailty: 6.0 to 7.8 drugs; robust: 2.0 to 2.9
Using US national survey data from 1999 to 2020 for 12,766 community-dwelling adults aged 65 or more, this study tracked medicine use by frailty level.
The average number of prescriptions rose from 2.0 to 2.9 in robust adults, 3.9 to 5.5 in mildly frail adults and 6.0 to 7.8 in moderately to severely frail adults. Cardiovascular drugs made up the largest share but stayed stable; the rise came from metabolic drugs across all groups and from CNS and psychotropic drugs mainly in the most frail.
The frailest patients have the most drugs, the least reserve and the shortest horizon to benefit from preventive medicines. Medication review should scale with frailty, with psychotropic and metabolic drugs among the first to examine.
- Assess frailty and let it set the intensity of medication review
- Review psychotropic and sedative drugs first in moderately to severely frail adults
- Relax glucose-lowering targets where frailty limits benefit and raises hypoglycaemia risk
- Ask what each drug is for and whether the expected benefit is still within the patient's horizon
- Record deprescribing decisions so they are not reversed at the next admission
Why it matters
Medication burden is climbing fastest in the group least able to tolerate it.
Don't overread it
Descriptive trends; it does not show which drugs are inappropriate for any individual.
The statistics, in plain English
An average of 7.8 prescriptions means many frail adults take ten or more. These are survey-reported counts, not measures of harm.
