Private hospital management shows better performance, particularly in high-survival probability cases. This study defines hospital output as changes in survival probability distributions, enabling a clearer assessment of management efficiency.

Area of Science:

  • Health economics
  • Health services research
  • Management science

Background:

  • Healthcare systems face pressure for reform in financing and delivery.
  • Hospital care efficiency is a key area of focus for healthcare reform.
  • Private management is explored as a strategy to enhance healthcare delivery efficiency.

Purpose of the Study:

  • To develop a methodology for assessing hospital performance.
  • To evaluate hospital efficiency by treating hospitals as unique firms.
  • To compare the performance of private versus public hospital management.

Main Methods:

  • Defined hospital output as a change in the distribution of survival probabilities.
  • Separated hospital production from patient characteristics using this output definition.

  • Utilized the concept of stochastic dominance to define and measure "better performance".

    • Main Results:

    • Private management demonstrated superior performance compared to public management for a specific Diagnosis-Related Group (DRG).
    • The performance advantage of private management was most pronounced in the range of high-survival probabilities.
    • Performance differences were not attributable to input prices or economies of scale/scope.

    Conclusions:

    • Hospital performance can be precisely measured by changes in survival probability distributions.
    • Private management exhibits technological and organizational advantages leading to better performance.
    • The study provides a novel framework for evaluating hospital efficiency and management strategies.
