Japanese anesthesiologists’ knowledge of the cost of medicines and their attitudes toward cost containment: a cross-sectional survey

Objectives: This study surveyed Japanese anesthesiologists’ knowledge of the cost of medicine and their attitudes toward cost containment to determine how these factors may affect their choice of medication and provide insight into reducing healthcare expenditures. Materials and Methods: In this cross-sectional study, Japanese anesthesiologists’ knowledge of medicine prices and their attitudes toward cost containment were surveyed to identify barriers in lowering the cost of anesthesia. The proportion of participants who correctly guessed the cost of the five most frequently used types of drugs within 25% of the actual price was determined, and their attitudes regarding drug prices and barriers to achieving cost containment were analyzed. Results: In total, responses to 60 questionnaires were analyzed. The proportion of participants correctly guessing the price within 25% of the actual price for each of the five drug categories, including neuromuscular blocking agents, inhaled anesthetics, intravenous anesthetics, opioids, and neuromuscular blockade reversal agents, was 30% (n=18), 18.3% (n=11), 6.67% (n=4), 30.0% (n=18), and 63.3% (n=38), respectively. Participants believed they had adequate access to information on prices, that the cost of a product influenced their decisions regarding product use, and that more information about cost might change their use of the drugs but did not believe that they had adequate knowledge about product prices. Conclusion: The proportion of participants with acceptable price estimates is small. Educating anesthesiologists about the cost of anesthetic agents may be required to encourage cost-containing behaviors. This study is the first survey to assess Japanese anesthologists’ knowledge of the cost of medicines.
