Physicians' perceptions and knowledge of drug costs: results of a survey

The objective of this survey was to determine physicians' opinions of the importance of drug costs, sources of drug cost information used, preferences for mechanisms to lower drug costs, and to assess knowledge of the relative cost of common drugs. A questionnaire containing opinion statements and five categories of drugs to be ranked from least to most expensive was sent to 598 physicians at our tertiary-care, university-affiliated teaching hospital. In all, 398 (66.6%) surveys were completed. Survey results indicate that physicians are interested in lowering the cost of drug therapy, and that they are knowledgeable of relative drug costs but would like more cost information to make more informed prescribing decisions. Most believe that a readily available drug cost index is the most beneficial mechanism to decrease drug expenditures.
