Parameter | Data Source |
---|---|
Burden (macro models) | Mortality Data: â– WHO Global Burden of Disease reports [[18, 26] â– Demographic and Health Surveys (DHS)[27] â– Multiple Indicator Cluster Surveys [28] Morbidity Data: â– DHS â– Published literature |
Risk of Infection (micro models) | â– Published literature â– UNAIDS or WHO reports (for epidemic data) [29, 30] â– PSI population-based surveys (for behaviors such as sexual behavior or drug use behavior) [31] |
Efficacy/Effectiveness | â– Published randomized controlled trials, community randomized trials â– Child Health Epidemiology Reference Group (CHERG) reviews [32] â– Cochrane Literature Review [33] â– WHO Global Burden of Disease reports |
Attrition, or Wastage | â– PSI supply chain studies (as of 2011) â– PSI population-based surveys (as of 2011) â– Communication with PSI programmers Note: Wastage data are rarely available in the published literature so wastage levels were assumed until 2011. |
Utilization (including adherence) | Utilization Data: â– PSI population-based surveys â– USAID CYP conversion factor for family planning products [34] â– Published literature Adherence Data: â– Published literature â– PSI product usage studies (e.g., pill counts in HAART program) â– Communication with experts in the field Note that protective efficacy/effectiveness studies, such as CHERG reviews, are likely to have adherence/compliance data embedded in them already. |
Time frame | Defined as one year. For products/services with lifespans longer than one year, all years of impact are counted in the year of distribution. |
Disability Weight | Global Burden of Disease and Risk Factors [18] |
Duration of Disease or Disability | Published literature |
Age at Death due to Disease or Disability | â– Age distribution data of age at death â– Weighted estimates of age at death based on age group data from Global Burden of Disease and Risk Factors [18] |
Life Expectancy | WHO, 2011 (for Japanese life expectancy data) [35] |
