Manufacturers' distribution of drug samples to a family medicine clinic.

The distribution of drug product samples by pharmaceutical companies to a family medicine clinic was studied. Data on all deliveries of drug samples to the clinic site of a university-affiliated family medicine residency program from November 1992 through December 1993 were collected. In addition, the 11 faculty family physicians were surveyed about their experiences with the deliveries of samples. Forty-three manufacturers delivered samples of 331 drugs during the 14-month study period. There were 366 visits by the drug company representatives, who made 1117 separate deliveries. The total value of the samples, based on the average whole-sale price, was $240,782. Twenty-nine percent of the drugs were nonformulary, and only 49% were stocked by the pharmacy. The physicians surveyed indicated that they were either usually or always asked to sign for samples they did not in fact request, that they usually did not know what was recorded on the receipts for samples that they signed, and that they seldom verified what was actually delivered. Pharmaceutical manufactures delivered large quantities of drug samples during the study period, and many of the drugs were nonformulary or not stocked by the pharmacy. The physicians indicated that they were not well informed about delivered samples for which they signed receipts.
