Heterogeneity in Hospital Consolidation

This paper examines the heterogeneity between two types of hospital consolidations—mergers and system-joinings. I examine changes in admissions, employment outcomes, beds in different medical units, surgeries, costs, case mix, and discharges. I find that hospital mergers and system-joiners are fundamentally different among almost all outcomes examined. Additionally, I extend my analysis by examining those hospitals that, at the time of consolidation, are closer to either their fellow merging hospital or a fellow system-member hospital. I find no meaningful correlation between distance and outcomes.
