A model for collaboration in quality improvement projects: implementing a weight-based heparin dosing nomogram across an integrated health care delivery system.
BACKGROUND
At Aurora Health Care, an integrated delivery system based in Milwaukee, a system-level clinical quality improvement department was established in 1995 to facilitate collaboration on clinical quality improvement (QI) initiatives.
A model was developed to use expertise within the system and avoid unnecessary duplication of efforts, while maintaining buy-in for the project's interventions at the point of service delivery. It was believed that a single team could design the improvement efforts or guidelines, and then work at a more local level with a different group of people to implement the processes.
Anticoagulation with heparin is considered the mainstay of treatment for pulmonary embolism and deep venous thrombosis. However, a large gap was found between present anticoagulation practices and published best practice in regards to achieving a key process measure. To reduce the overall time to achieving effective anticoagulation, a system-level team created an intervention primarily consisting of a preprinted order sheet, including the weight-based heparin dosing nomogram, and an education plan for physicians and other health care professionals. Significant improvement was observed at all pilot sites with overall rates of adequate anticoagulation within the first 24 hours improving from 73% to 95%.


CONCLUSIONS
The system was able to standardize care at four of its five major hospitals and provide for better patient outcomes to a larger segment of the community, and then to replicate the heparin project to four additional sites during a six-month period. This model has been successfully applied to other quality improvement projects.
