Cost-effective osteoporosis treatment thresholds for people living with HIV infection in Greece
Abstract
Objectives: We aimed to specifically define the FRAX-based cost-effective treatment thresholds for osteoporosis among people living with HIV (PLWHIV) in Greece and to compare them with those of the general population.
Methods: A previously described state transition Markov cohort model was used in order to estimate the cost-effective intervention thresholds for osteoporotic therapy among Greek PLWHIV employing the FRAX® tool. The model-derived relative risk at which an incremental cost-effectiveness ratio of 30,000€/QALY gained was observed for treatment versus no intervention was multiplied by the average Greek FRAX-based 10-year probabilities for both major osteoporotic and hip fractures.
Results: There exists no significant difference in the cost-effective FRAX® based thresholds between PLWHIV and general population. The absolute 10-year probabilities of 2.5 and 10% for hip and major osteoporotic fractures, respectively, could be used for the initiation of treatment for PLWHIV of both genders under the age of 75; for older subjects the proposed intervention threshold is raised to 5 and 15% 10-year probability for hip and major osteoporotic fracture, respectively.
Conclusions: Our study confirms the general recommendation for the use of country specific FRAX® thresholds when managing bone fragility within PLWHIV. In any case, clinical judgment and appropriate screening are mandatory and irreplaceable.
