HIV Drug Treatment Expenditures at the Instituto Mexicano del Seguro Social (IMSS) Cuernavaca Morelos, Mx. August 1st, 2008.
Background • Antiretrovirals (ARVs) are essential for individuals who live with HIV, but they are the most expensive component of HIV care. • After the Ministry of Health (SSA), the IMSS is the second most important provider of ARVs in Mexico, with about 18,000 patients under treatment in 2006. • Since 2001, the IMSS has had universal free access to ARVs; nevertheless, information about ARV costs is scarce.
Objective To provide empirical evidence on: • Institutional Purchasing Prices. • Total Expenditures on ARVs. • Average Expenditures per IMSS beneficiary under treatment.
Methodology Identification of ARV purchased and their providers (2002-2006) through the IMSS Purchasing Database The nominal prices were deflatedinto constant prices, using 2006 as the base year. Regression Model For predicting future data Calculation: ARVs Total Cost, Average Cost Per IMSS Beneficiary, per Therapeutic Group, and type of treatment First & Second Line (WHO)
Results • The purchasing prices for 28 ARVs exhibit a declining trend: median reduction was 11.9%. • Most of ARVs were bought from distributors, or from indirect providers (not directly from the labs). • The main distributors were: • Fármacos Especializados • Selecciones Médicas • Ralca
Conclusions • The purchasing prices show a lightly decreasing trend. • There is a rising trend in the total expenditure on ARV. • There is also a rising trend in the expenditure per IMSS beneficiary under ARV treatment. • Hypotheses: • Changes into second-line treatment • Shortage reductions / Advanced purchasing • This is one of the very few empirical works about this subject.
Limitations • The reliability of the database. • Short time-series. • Estimated number of beneficiaries (CENSIDA´s Information). • Nevertheless, first analysis of the only public-access source.
