1 To enhance comparability, all costs in this table are presented in 2008 International dollars (I$) using GDP deflators and purchasing power parities available from the International Monetary Fund [54].
2 Numbers in round brackets correspond to the intervention strategies presented in Table 1. Although several studies comparing multiple strategies also provide incremental results [27-29,40], results comparing individual strategies to a do-nothing alternative are presented where possible. The exception is [28].
3 SOC = Societal (considers direct and indirect costs); PPHC = Public payer of healthcare costs (considers direct costs only); PRO = Provider (considers direct medical costs covered by the facility)
4 QALY = Quality-adjusted life years
6 DALY = Disability-adjusted life years
6 These are the study authors' conclusions about the value of one or more interventions to prevent MTCT of HIV. If a benchmark was used to justify the conclusion, it is provided in brackets.
7 Study based on older (higher) drug prices and lower regimen effectiveness.
8 The 1993 World Development Report: Investing in Health proposed that interventions costing less than $100 per life year saved are cost effective for middle-income countries while $50 per life-year gained is a reasonable benchmark for low-income countries [33]. This was updated to $64 per QALY in low-income settings ($50 per QALY gained, adjusted to 2003 dollars) by [26] and [29].
9 CS = Cost saving
10 Concentrated epidemic; very low HIV prevalence.
11 Three-letter country codes published by the International Organization for Standardization (ISO). See Table 3.
12 Authors used the Thai health system's thresholds for adopting health technologies as a benchmark.
13Authors' conclusions comparing the effectiveness of an ARV-based regimen (pMTCT component 3) to a family planning strategy (pMTCT component 1). Both strategies would likely be cost-effective using standard benchmarks.
14 The WHO Commission on Macroeconomics in Health proposed that interventions costing 1*GDP per capita per DALY should be considered "very cost-effective", while those costing <3*GDP per capita should be considered "cost-effective" [44].
