Small is Not Beautiful: A Critique of Antitrust Economics and Policy in Health Care.

For example, many hospital systems compete in overlapping markets for primary care, specialty procedures, drug infusion, home health, subacute care, transplant surgery, telemedicine, population health management, and other services beyond traditional acute inpatient care.
