Objective To perform a cost-effectiveness and budget impact analysis from the perspective of the Spanish public healthcare system (SHS) to compare the number of overnight hospital stays avoided under a community and a hospital pharmacy model due to the administration of intravenous anti-infective therapy (IVAT) at a nursing home with 145 beds.
Methods Analytical, observational, retrospective cohort study of a nursing home in Galicia (north-west Spain) that switched from a community to a hospital pharmaceutical management model. We compared the number of IVAT administrations, the number of hospital transfers and stays avoided, and mean annual costs avoided by the SHS before and after the switch. Costs were calculated using official SHS rates.
Results The switch from the community to the hospital pharmacy model resulted in 2.8 more IVAT administrations (95% CI, 2.71 to 2.88) and 20.79 fewer overnight hospital stays (95% CI, 20.07 to 21.51) per 100 nursing home beds a month (p<0.001). The net monthly avoided cost for the SHS was 9971.52 €2019. The budget impact analysis showed that implementation of this model throughout Galicia and Spain would respectively avoid costs of 13.78 and 221.21 million €2019 a year.
Conclusions Hospital pharmacy models can contribute to a better optimisation of public healthcare resources and help improve the sustainability of the SHS.
