Stent costs decrease without warfarinInvestigators have found an overall decline in costs of stent cases when warfarin anticoagulation is abandoned.1As stenting practice has evolved, concern has focused on the increasing delivery costs. To evaluate changes, researchers examined total costs; costs for catheterization, laboratory equipment, and equipment use; and nonlaboratory hospital costs for stents in two time periods, one involving routine warfarin anticoagulation and one in which warfarin was not used.
- Overall costs dropped from the first period ($11,293 ± $7672) to the second ($9,819 ± $3,636).
- Cath lab equipment expenditures rose from the first period ($3,823 ± $1,394) to the second ($4,278 ± $1,533).
- Non-cath-lab hospital costs declined from the first period — $7,281 ± $7,179 — to the second — $5,560 ± $3,420.
