Clinical and economic effectiveness of an inpatient anticoagulation service.
We conducted a prospective cohort study to evaluate clinical and economic end points achieved by a pharmacist-managed anticoagulation service compared with usual care (50 patients/group). The primary therapeutic end point was the time between starting heparin therapy and surpassing the activated partial thromboplastin time therapeutic threshold. The primary economic end point was the direct variable cost of hospitalization from admission to discharge. No significant differences between groups were noted for the primary therapeutic end point. Total hospital costs were significantly lower for patients receiving pharmacist-managed care than for those receiving usual care ($1594 and $2014, respectively, 1997 dollars, p=0.04). Earlier start of warfarin (p=0.05) and shorter hospital stay (5 and 7 days, p=0.05) were associated with the pharmacist-managed group.
