Hot spotting surgical patients undergoing hepatopancreatic procedures.

BACKGROUND: The burden of health care spending in the United States is a major concern, as health care costs have exponentially increased during the last three decades. The objective of the current study was to investigate the degree of cost-concentration among Medicare patients undergoing liver and pancreatic surgery.
METHODS: Medicare claims data from 2013 to 2015 were used to identify patients undergoing elective liver and pancreatic resections. Patients were divided into four groups: 1) non-complex pancreatic procedures; 2) complex pancreatic procedures; 3) non-complex liver procedures; and 4) complex liver procedures. Unadjusted price-standardized Medicare payments were calculated and payments were divided into quintiles. Patient-level factors associated with payments were analyzed by multivariable linear regression.
RESULTS: A total of 17,125 patients were included in the study. Patients in the top quintile of spending accounted for over 40% of payments for all liver and pancreatic procedures. Patients with comorbidity scores ≥5, male sex, open surgical approach and a diagnosis of congestive heart failure were associated with higher costs.
CONCLUSION: Patients undergoing liver and pancreatic resections on the top 20% of payments were responsible for a disproportionate share of Medicare payments - over 40% of total expenditures. Overall hospital surgical volume was lower among the highest quintile of payments.
