From: Effects of the cefazolin shortage on the sales, cost, and appropriate use of other antimicrobials
Linear regressions of reimbursement costs on defined daily doses in total parenteral antimicrobials before and after the cefazolin shortage. A, Black dots represent April to December 2018 (before the cefazolin shortage). B, White triangles represent January to September 2019 (after the cefazolin shortage). Gray zones represent 95% confidence intervals. Coefficients of formulas between A and B were similar, thus, it is considered that the reimbursement cost per defined daily dose did not change between before and after the cefazolin shortage
