$1 Billion in Medications for the Elderly May Be Wasted
October 18, 2001
Unused pills may account for more than $1 billion in drug costs among elderly Americans each year, according to a study in the Journal of Family Practice.
Thomas M. Morgan of the Yale University School of Medicine in New Haven, Conn., and associates interviewed 73 retirement-community residents aged 65 and older with full prescription-drug coverage. They also visited the participants' homes to take prescription-pill counts.
The investigators found wasted pills accounted for a little more than 2.3 percent of the residents' total yearly medication costs. Although the average individual cost of $30.47 was "modest," this per-person price tag adds up. Extrapolated to the whole U.S. elderly population, it suggests discarded or unused pills tops cost $1 billion annually.
The main causes of waste included:
- Resolution of the condition for which the medication was prescribed (37.4 percent).
- Patient-perceived ineffectiveness (22.6 percent).
- Prescription change by the physician (15.8 percent).
- Patient-perceived adverse effects (14.4 percent).
Antibiotics, high blood pressure medication and benzodiazepines -- a drug class that includes treatments for anxiety and insomnia -- were the most frequently wasted drugs. Drugs for acute conditions, rather than chronic illnesses, appeared to account for most of the unused medication, according to Morgan.
