Lopinavir/ritonavir capsule recipients would gain 4.6 quality-adjusted life-months (QALMs) compared with atazanavir plus ritonavir recipients; this benefit would increase to 5.6 QALMs with the use of lopinavir/ ritonavir tablets. Over the first 5 years of treatment, lopinavir/ritonavir capsules would provide total healthcare cost savings of $US12 284 compared with the atazanavir plus ritonavir regimen; over 10 years of treatment, the savings increased to $US14 117. Despite the additional costs of longer survival incurred by lopinavir/ritonavir recipients, lifetime savings of $US3600 may be expected with this regimen. * one of the researchers was affiliated with Abbott Laboratories ** Costs (2005 values) included direct costs only and were calculated from a healthcare system perspective.
