Background: The objective of this study was to determine if anesthesia providers can accurately estimate the cost of commonly used medications, supplies, and blood products.
Methods: This study was conducted between April and June 2019 at an academic tertiary care hospital. Anesthesia providers (certified registered nurse anesthetists [CRNAs], residents, and fellows/attendings) were surveyed on their knowledge of the cost of commonly used therapies. Items were sorted into 12 categories: opioids, non-opioid analgesia, vasopressors, hypertension medications, antibiotics, neuromuscular blockers, reversals, anesthetics, supplies, kits, blood products, and blood-related products. Estimates were considered to be accurate if the median cost differed from the average wholesale price by < 25%, moderately inaccurate if between 25% and 50%, and severely inaccurate if by > 50%.
Results: A total of 107 surveys (CRNAs: 25, residents: 36, fellows/attendings: 46) were returned. The percentage of total items accurately estimated for cost was low (22% for all providers), and was not different between provider types (27% for CRNAs, 23% for residents, 20% for fellows/attendings; p = 0.69). The percentage of items with severe inaccuracies in cost estimation was high and was not different between provider types (56% for CRNAs, 60% for residents, 50% for fellows/attendings; p = 0.53). Rates of under- and overestimation varied widely, with greatest underestimation for vasopressors and blood-related products, and greatest overestimation for non-opioid analgesia and antibiotics. Low- and high-cost category items tended to be overestimated and underestimated, respectively (p < 0.0001).
Conclusion: The majority of anesthesia providers have poor knowledge of cost. These findings suggest that cost awareness interventions may be necessary for promoting high-value health care.
