A policy option towards improving efficiencies in Victorian public oral healthcare.

ABSTRACT

BACKGROUND: International oral health policy directions led by the World Health Organisation call for the inclusion of oral health within universal health coverage. The aim of this study is to perform a budget impact analysis of a policy option for a more cost-efficient oral health workforce skill-mix (dentists and oral health therapists) to provide public oral healthcare in Victoria, Australia. METHODS: Two hypothetical standard care pathways were developed. A dynamic population Markov model in TreeAge software, with a time horizon of 6 years. Two scenarios were modelled to determine (1) base-case scenario the threshold the dentist workforce could reduce per year, while achieving the same service delivery outputs, and (2) alternative scenario the potential cost-savings for utilising an optimally cost-efficient oral health workforce skill-mix. RESULTS: The threshold analysis showed a minimum reduction of 13% of the dentist workforce being replaced with oral health therapists can occur without having any impact on the same service delivery outputs. Under the alternative scenario, the potential cost-savings would be AUD$1,425,037 (standard deviation 58,954). CONCLUSIONS: Governments and policy-decision makers should consider strategies in training, attracting, and retaining oral health therapists to achieve an optimally cost-efficient oral health workforce skill-mix when delivering public oral healthcare.
