Does Hospital Competition Improve Efficiency? An Analysis Of The Recent Market-based Reforms To The English NHS
This paper uses a difference-in-difference estimator to test whether the introduction of patient choice and hospital competition in the English NHS in January 2006 has prompted hospitals to become more efficient. Efficiency was measured using hospitals' average Length Of Stay (LOS) for patients undergoing elective hip replacement. LOS was broken down into its two key components: the time from a patient's admission until their surgery and the time from their surgery until their discharge. The authors' results illustrate that hospitals exposed to competition after a wave of market-based reforms took steps to shorten the time patients were in the hospital prior to their surgery, which resulted in a decrease in overall LOS.
