Clinical benchmarking improves clinical paths: experience with coronary artery bypass grafting.

BACKGROUND

Clinical paths and clinical benchmarking are consistent with, and readily adaptable to, any health care organization that espouses the principles of continuous quality improvement.

CLINICAL PATHWAY

In its initial clinical path project, Borgess Medical Center analyzed and streamlined the processes of caring for a coronary artery bypass graft (CABG) patient. Team discussions were driven by comparative data, specialty guidelines, peer review organization guidelines, patient financial statements, patient records, and the applicable literature. One year after the CABG clinical paths were implemented, average total charges to the patient dropped from $35,700 to $32,700. Average length of stay also dropped, from 11.1 to 9.7 days. The mortality rate held stable at 2.7%.

CLINICAL BENCHMARKING

Recognizing the opportunity to further improve its CABG clinical path, Borgess participated in MediQual's CABG benchmarking project. The team followed MediQual's five phases of clinical benchmarking: focus and opportunity assessment, outcome analysis and comparison, clinical process documentation, benchmark process comparison, and action planning, implementation, and monitoring. Using benchmark data provided by MediQual, the CABG benchmark team focused on the high-risk population and identified further opportunities for streamlining the CABG clinical pathway. Several areas for improvement were identified by comparing Borgess's practices to the benchmark hospitals.

CONCLUSION

Developing a clinical path before beginning to benchmark "forced" Borgess Medical Center to develop a clear understanding of its own processes. This allowed the benchmark team to easily identify variances between its CABG processes and those of the benchmark hospitals and to select which variations the hospital should adopt.
