Cost-consciousness among Iranian internal medicine residents.

Study aimed at assessing residents' cost awareness and their attitude about health care costs. Internal medicine residents at teaching hospitals of Tehran University of Medical Sciences were surveyed during August-December 2016 using a researcher-made questionnaire comprising attitude statements and cost estimation of diagnostic and treatment items. Eighty-nine residents completed the survey (response rate = 56.6%). The results indicate that less than one quarter (23.69%) of cost estimates were in the range of correct answers. The mean (SD) for correct estimation of medications (out of 8 scores), lab tests (out of 20 scores), and total (out of 35 scores) were 1.25 (0.96), 4.92 (0.27), and 7.97 (0.34), respectively. An analysis of variance showed that the level of residency was positively correlated with residents' correct cost estimation ( (3, 77)=9.98,  = 0.029). There was a significant positive correlation between age of residents with the correct estimate of medication prices ( = 0.018,  = 0.261). The internal medicine residents of Tehran University of Medical Sciences have poor knowledge of health care costs, including medications, diagnostic tests, and hospitalization costs. The results of this study explain the necessity of developing a training program for the transfer of cost information to physicians.
