Hospital costs, cancer patients, and surgical diagnostic related groups.

This study of 4,359 Medicare patients in 107 noncancer stratified surgical Diagnostic Related Groups (DRGs) tested the hypothesis that patients with a diagnosis of a malignancy (i.e., cancer) in these DRGs would have higher resource utilization than patients without a diagnosis of a malignancy (i.e., noncancer) in these same surgical DRGs. The 1,008 cancer patients had 3.2 times the financial loss ($1,617 per patient vs. $510 per patient) compared to the 3,351 noncancer patients (P less than .05). Patients with cancer had a greater percentage of outliers, more diagnosis (P less than .0001) and procedures (P less than .0001) per patient, and a higher mortality (P less than .01) than patients without cancer. These findings raise the question of the equity of DRG payment for patients with cancer in many surgical DRGs. Financial disincentives to treat certain groups of Medicare cancer patients at our hospital may affect both their access and quality of care in the future.
