Country reports • Overall picture of country programs • Provides between-site comparisons • Separate for adults and pediatric patients
Country reports Adult patients Mozambique

Country reports Adult patients Mozambique Figure 4.7 Proportion of patients receiving tuberculosis treatment at ART initiation among adult patients initiating ART in the last year The overall percentage is represented by a horizontal line
Site reports • Provide in-depth, site-specific feedback for program improvement to ICAP staff, as well as site and district staff • Describe patient characteristics at enrollment and at ART initiation and patient outcomes
Site reports Jose Macamo General Hospital Mozambique Table 3.2 Measures of immunodeficiency status at ART initiation: active patients currently on ART a: window period three months prior and one month post b: according to WHO guidelines
Site reports Jose Macamo General Hospital Mozambique Figure 3.4 Weight-for-age z-score at ART initiation: active children1 < 15 yrs currently on ART (CDC standard) Weight-for-age missing: 22 Weight-for-age out of range (z-score <-10 or >10): 10 Moderately or severely malnourished (z-score < -2): 87 (31.9%) Severely malnourished (z-score < -3): 44 (16.1%)

ICAP Standards of Care (SOC) reports • Use patient-level data to calculate SOCs • Useful to identify site-level areas in need of improvement • All patients as opposed to a sample of patients • Easily assess trends

What is Operations Research? “Operations research is being defined broadly and includes the use of analytical techniques to achieve better health outcomes, define optimal processes of service delivery, and develop more cost-effective systems. It encompasses a wide range of studies, including observational and outcomes studies, epidemiological modeling, and cost-effectiveness studies.” • From the Doris Duke Charitable Foundation, ORACTA program

Identifying Optimal Models of HIV Care • Goals: • Assess the variation in key HIV care and treatment outcomes within & across sites and countries • CD4/WHO stage at enrollment & ART initiation • Non-retention, loss to follow-up, and death • Treatment failure and regimen switching • Identify factors at multiple levels associated with patient & program outcomes, with a particular focus on program-level factors
Example 1 Fig 1. Distribution of HIV disease status at ART initiation for the 24,273 eligible patients • Definition of advanced HIV disease at ART initiation (late ART initiation) • CD4 count <100 cells/µL • or • WHO Stage IV Fig 2. Variability of the proportion late ART initiators by site Overall proportion 52% Factors associated with Late ART initiation
Example 2 Retention of ART patients • Two year LTF and known deaths among ART patients Overall LTF29% Overall death 5%

Uses of common patient-level data warehouse Data Quality
Strengths • Service delivery data from scale-up programs • Multiple countries and contexts • Adults and pediatrics • Longitudinal • Retrospective to program start • Data from pre-ART phase of care • Variety of exposures and outcomes • Ability to examine impact of interventions, changes in guidelines, etc. • Large sample size
Limitations • Missing data (completeness) • Incomplete data entry • Incomplete documentation • Incomplete care • Inaccurate data • Single data entry • High rates of loss to follow-up • A mixed bag of unascertained deaths, transfers, and drop outs • Precludes meaningful examination of survival as an outcome

Conclusions • Over 154 of 510 (30%) ICAP-supported care and treatment sites have patient-level databases • 84 sites in 5 countries (17%) are submitting data to ICAP-NY on a quarterly basis. Warehouse includes: • 229,908 of 754,086 pre-ART patients represented: 30% • 95,851 of 367,179 ART patients: 26% • Data quality and completeness will be an ongoing challenge • Timely routine feedback/dissemination process in place • Program evaluation • Program improvement • SOC report • Will help shed light on and address data quality issues • Platform for multi-country operations research in place (Optimal Models protocols)
Future directions • Feedback and dissemination, utilization, analysis • Need to understand more about reasons for missing data for key variables, and how to impact it • Improving with time for some variables (e.g. CD4 at ART initiation) and not others (e.g. height) • Improve ability to examine survival as an outcome
