- Abstract: Healthcare programs such as Medicaid provide crucial services to vulnerable
populations, but due to limited resources, many of the individuals who need
these services the most languish on waiting lists. Survival models, e.g. the
Cox proportional hazards model, can potentially improve this situation by
predicting individuals' levels of need, which can then be used to prioritize
the waiting lists. Providing care to those in need can prevent
institutionalization for those individuals, which both improves quality of life
and reduces overall costs. While the benefits of such an approach are clear,
care must be taken to ensure that the prioritization process is fair or
independent of demographic information-based harmful stereotypes. In this work,
we develop multiple fairness definitions for survival models and corresponding
fair Cox proportional hazards models to ensure equitable allocation of
healthcare resources. We demonstrate the utility of our methods in terms of
fairness and predictive accuracy on two publicly available survival datasets.

Continual care deferral in populations may lead to a decline in population health and compound health issues leading to higher social and financial costs in the long term.
Minority and vulnerable populations are at a greater risk of care deferral due to socioeconomic factors.
Many health systems currently use rules-based techniques to retroactively identify patients who previously deferred care.
The objective of this model is to identify patients at risk of deferring care and allow the health system to prevent care deferrals through direct outreach or social mediation.

This paper studies a model that protects the privacy of individuals' sensitive information while also allowing it to learn non-discriminatory predictors.
A key characteristic of the proposed model is to enable the adoption of off-the-selves and non-private fair models to create a privacy-preserving and fair model.

Our models performed 20% better than the insurance carrier's existing pricing model, and identified 84% of the concession opportunities
