Does Private Equity Hurt or Improve Healthcare Value? New Evidence and Mechanisms
🤖 AI Summary
This study examines how private equity (PE) investment affects healthcare value in U.S. hospitals and whether health information technology (IT)-enabled information sharing mitigates this impact. Using a national panel of U.S. hospitals from 2008–2020, we employ an event-study–based staggered difference-in-differences design to identify causal effects. Results show that PE acquisition significantly reduces healthcare value—evidenced by lower cost efficiency and higher readmission and infection rates. However, cross-setting information sharing between hospitals and outpatient facilities meaningfully attenuates these adverse effects, outperforming intra-hospital or inter-hospital sharing alone. This paper provides the first empirical evidence of information sharing as a moderating mechanism in PE governance of healthcare organizations. It underscores the critical role of IT-enabled collaborative governance in preserving post-acquisition quality and cost-effectiveness, offering rigorous evidence to inform policy design on capital participation in healthcare systems.

📝 Abstract
What is the impact of private equity (PE) investment on healthcare value? Does PE investment hurt or improve healthcare value, and if so, can its effect be mitigated through the use of health information technologies (IT)? Given the significant investments by PE firms in the healthcare sector in recent years, these are important research questions. Stakeholders, including policy makers, care providers, and patients, need to understand their likely impact and whether PE ownership is aligned with their interests. Using a staggered difference-in-differences approach and data from US hospitals from 2008-2020, we observe that the overall value of healthcare delivered by hospitals declines after PE investment. However, our empirical evidence reveals that IT-enabled, health information sharing plays an important moderating role. Hospitals with stronger information-sharing capabilities exhibit greater cost efficiencies and improvements in care quality, leading to higher healthcare value after PE investment. Furthermore, we find that the type of health information sharing matters. Specifically, we observe that improvements in care quality are primarily driven by information sharing between hospitals and ambulatory care providers, instead of simply hospital-to-hospital sharing of patient health data. Our research also identifies the underlying mechanisms through which health information sharing improves care value by reducing hospital-acquired infections and readmission rates, thereby improving care quality, and enhancing labor productivity by reducing operating costs. Our results highlight the critical role of policies and common data standards needed to promote IT-enabled information sharing between healthcare providers, which, in turn, can align incentives of PE firms with the goals of value-based care.
