How Insurable Is HIV Disease?

Potential conflicts

• Chief medical officer ACHMEA, division Pension & Life• Working Group HIV (1996-2011) and Committee

Medical Ethical Affairs (2010-present) of the Association of Insurers

• Risk calculations performed by the independent HIV Monitoring Foundation for the Working Group HIV • You’re allowed to use the risk models in your

company• CLIMOA/ACDMAV is allowed to distribute this

presentation among members and praticipants

Learning Objectives

• The importance and the impact of the Dutch HIV-insurance models in the Netherlands

• The basic principle, assumptions, and restrictions of the models

• The limitations of the results

• The internal and external validity of the models:What should be done before you can use these models in Canada?

1992 : legislative proposal: total ban on testing

1993 : Code of Conduct: testing allowed in case of…

-blood transfusions in certain countries,-needle sharing, -anal gonorrhoea,-high sums insured.

1996 : Working Group HIVto study insurability

Conclusions

WHY? Political pressure

WHO? Select real prospects only

HOW? Predictive models by independent scientists (HIV Monitoring Foundation)

Limitations Favourable reference population (underestimation of true risk); Dependent on type of adverse selection

Canada/US? Disease spectrum of applicants / adverse selection
