A comparative performance analysis of a renowned public private partnership for health care provision in Spain between 2003 and 2015.

Background: Recently, the once archetype of the public private partnership (PPP) in the Spanish National Health System (SNHS), namely the Alzira's Model, has come to an end. Advocates defended the superiority of PPPs over public-tenured provision, in terms of quality and technical efficiency. This paper profiles and compares Alzira's life-cycle performance with similar public-tenured providers.

Methods: Observational study on secondary data from virtually all hospital care episodes produced in 51 integrated providers (i.e., administrative healthcare areas) and 67 hospitals, in 2003 and 2015. Alzira's 2015 performance (and its variation since 2003) was compared with all public-tenured peers in the SNHS, using 26 indicators analysing the differences in age-sex standardized rates of events or risk-adjusted mortality, severity-adjusted hospital expenditure and hospital technical efficiency.

Results: In comparison with the corresponding public-tenured peers, Alzira's 2015 performance was statistically worse than the benchmark in the majority of indicators (15 out of 26); yet, its performance was one of the best in the SNHS in adjusted-mortality after Percutaneous Coronary Intervention (PCI). Over time, Alzira showed a statistically greater 2003-2015 improvement than its peers' average in eleven of the indicators, and a lower improvement in nine.

Conclusions: In this comprehensive comparative study on Alzira's performance, this PPP has not generally outperformed public-tenured providers, although in some areas of care its developments have been outstanding.
