What impact did the implementation of Diagnosis-Related Group 559 have on cost-reimbursement ratio for stroke care?
The implementation of Diagnosis-Related Group 559 favorably altered the cost-reimbursement ratio for stroke care. In a single-hospital study, this ratio decreased from 1.41 (95% CI, 0.98 2.28) before Diagnosis-Related Group 559 to 0.82 (95% CI, 0.66 0.97) after Diagnosis-Related Group 559. The subsequent years corresponded to a period of rapid growth in the number of primary stroke centers and increasing total stroke treatment cases.
