  1. Modelling the costs of paediatric HIV infection and AIDS : comparison of infected children born to screened and unscreened mothers.

    Article - En anglais


    To estimate the cost of managing children with HIV/AIDS in the UK from a health service perspective.

    Design and methods 

    Epidemiological, resource use and unit cost data were combined within a decision analytic model.

    A Markov model was developed to predict the prognoses of HIV-infected children under different assumptions about natural history, treatment efficacy and the timing of antiretroviral therapy.

    Resource use estimates for various stages of HIV/AIDS were based on published data relating to the UK health service and clinical judgement ; unit cost data were taken from a London centre.


    The base-case results suggest that the cost of caring for an HIV-infected child is higher if the mother's infection was known about at or before the child's birth (antenatal screened cohort) : lifetime costs ranged from £46 427 to £119 502 per child in the screened cohort and from £38 691 to £86 014 in the unscreened cohort.

    However, the screened cohort benefited from longer life expectancy (base-case, 11.66 versus 10.09 years) and AIDS-free life expectancy (base-case, 7.13 years versus 6.22 years).

    Results are sensitive to assumptions about natural history and treatment efficacy : for example, if antiretroviral therapy was initiated at birth, and assuming optimistic natural history parameters, discounted costs could increase to £215 077 and the additional lifetime cost of a child born to a screened mother could be £72 491.
