Hospitalist Co-Management of a Vascular Surgery Service Improves Quality Outcomes and Reduces Cost.

ABSTRACT

BACKGROUND: Hospitalists can be instrumental in management of inpatients with multiple comorbidities requiring complex medical care such as vascular surgery patients, as well as an expertise in health care delivery. We instituted a unique hospitalist co-management program and assessed length of stay, 30-day readmission rates and mortality, and performed an overall cost-analysis. METHODS: Hospitalist co-management of vascular surgery inpatients was implemented beginning April 2019, and data was studied until March 2020. We compared this data to an eight-month period prior to implementing co-management (7/2018 - 3/2019). Patient-related outcomes that were assessed include length of stay, re-admission index, mortality index, case-mix index. Cost-analysis was performed to look at indirect and direct cost of care. RESULTS: A total of 1,062 patients were included in the study 520 pre co-management and 542 patients were post-comanagement. Baseline case-mix index was 2.47, and post-comanagement was 2.46 (P >0.05). In terms of average length of stay (aLOS), the baseline aLOS was 5.16 days per patient, while after co-management it was significantly decreased by 1.25 days to 3.91 days (P <0.05). This improvement in length of stay opened an average of 2.4 telemetry beds per day. Similarly, excess days per patient which reflects the expected length of stay based on comorbidities, improved from -0.59 to -1.65, an improvement of -1.46. CONCLUSIONS: Hospitalist co-management improves outcomes for vascular surgery inpatients, decreases length of stay, re-admission and mortality while providing a significant cost-savings. The overall average variable direct cost decreased by $1,732 per patient.
