Program Science:Opportunities, Challenges and ImpactProgram Components and Issues James Blanchard, MD, MPH, PhD Professor and Director, Centre for Global Public Health University of Manitoba
What is a “Program” in the context of STI/HIV Prevention and Control? • Drawing on the public health concept: • “science and art of preventing disease” (Winslow, 1923) • “organized efforts of society to protect, promote, and restore the peoples’ health” (Last) • Focusing on the population level, and population-level impacts • Coherent planning, implementation and management processes and structures
Intervention vs. Program • Program • Multiple components (interventions) • Resource allocation between components, and sharing across components • Emphasis on optimizing population level impact • Intervention • Specific technological or behavioural modality • Particular target group(s) • Focus on effectiveness, fidelity, coverage
“Program Science” for HIV/STI Prevention:A Component Framework Spheres of Knowledge Spheres of Practice Intended Outcomes • Choose: • The best strategy… • The right populations… • The right time… • Epidemiology • Transmission dynamics • Policy analysis • Health systems research Strategic Planning Policy Development Program Implementation • Do: • The right things… • The right way… • Efficacy / effectiveness • Operations research Program Management • Surveillance • Monitoring/evaluation • Operations research • Health systems research • Ensure: • Appropriate scale… • Efficiency… • Change when needed…
Program Components • Strategic Planning • How will prevention be achieved and epidemics controlled? • Implementation System • What interventions will be deployed and how will they be delivered? • Program Management • How will the program be managed, monitored and evaluated?
Strategic Plan – Program Design • Setting prevention priorities and objectives: • Based on epidemiology and transmission dynamics to have population-level prevention impact • Specifies sub-population focus • Organized based on epidemic heterogeneity and/or health system structure • National program design • State / Provincial • District / Local
Issues in Strategic Planning • Epidemic appraisal and understanding the transmission dynamics • Balancing short, medium and longer term prevention objectives • Matching strategies to the level of implementation
Epidemic Appraisal and Transmission Dynamics • Recent upheaval in methodological approaches • The “numerical proxy” approach (1% / 5% rules) are being replaced by the “Modes of Transmission” methodology • Unclear link between typifying the epidemic and strategic plans • Previous blurring of response to “generalized” epidemics at 2-3% prevalence and >15-20% • Replaced by MOT with usual estimates that most new HIV infections occur in “low risk heterosexual partnerships”, regardless of HIV prevalence • Unclear approaches to “mixed epidemics”
Epidemic Appraisal and Transmission Dynamics (cont) • Inadequacy of data at all levels • Behavioural data are inconsistent, and often clearly inaccurate • Credible size estimation of different key populations often absent • Inconsistent coverage and methodology for biological surveys • Understanding epidemic phase and the trade-offs between short, medium and long term prevention objectives • In most mature epidemics a large % of new infections occur in the context of stable, low risk partnerships, but how much should prevention be focused there?
Examples of Key Strategic Planning Issues – India • How are the transmission dynamics different in the regions with persistently high prevalence, and what additional interventions might need to be used? • This includes strategies for the rural areas with high prevalence • What are the objectives and strategic options for the very large migrant population? • What are the future risks of emerging epidemics? • IDU?
Examples of Key Strategic Planning Issues – Kenya • Beyond circumcision, what are the differences in transmission dynamics in different regions? • General sexual structure, key populations • What is the relative contribution of key populations (FSW, MSM, IDU) to the epidemics in different regions? • What would be the impact of interventions in key populations? • To what extent should “general population” interventions be targeted? • Geographic? Socio-demographic?
Examples of Key Strategic Planning Issues – Nigeria • How should prevention resources and strategies be tailored to the high levels of epidemic heterogeneity? • What should be the population focus for preventive interventions in different contexts? • General population? • High risk subsets or locales? • Most at risk key populations?
Issues in Program Strategies – Levels of Application • Global / Regional • Prone to using “broad-brush” approaches or “campaigns” • Influences lower level strategy and policy, often through funding choices • Large international funders and NGOs sometimes focus on “most highly favoured” interventions • Country • Challenges include lack of specificity and complex processes for regional resource distribution • Often dealing with multiple donors with competing priorities
Issues in Program Strategies – Levels of Application (cont) • State / Province • Often influenced by “top down” approaches • Technical capacity constraints • District / Local • Often lack sufficient data and/or technical capacity for planning • Generally highly dependent on State / Provincial resources and decision-making
Issues in Implementation • Knowing what works • Tailoring interventions to local contexts • Horizontal programs and vertical interventions • Building capacity
Knowing What Works • Evidence for the efficacy and effectiveness of many behavioural interventions is lacking • When does that mean it won’t work? • Lack of knowledge about why some interventions appear effective in some contexts, and not others • What is the effect of combining interventions? • Addition, synergy or antagonism
Tailoring implementation to local contexts • Tension between standardized intervention packages and local adaptation • Flexibility in components • Flexibility in resources • Who decides, and on what basis? • What are the implications of a results-based approach (as opposed to common packages)? • Defining outputs and outcomes and indicators • How can intervention results be compared if there is variability?
Horizontal programs and vertical interventions • How can the tensions between scaling up vertical interventions across wide areas and establishing local implementation processes be managed? • How do you avoid the “cookbook” approach to implementation, while maintaining consistent standards and quality of implementation?
Building Capacity • Capacity for implementation is a key constraint at all levels, including: • Lack of trained managers at the implementation level • Paucity of good implementation resource material • Limited skills in using data to optimize performance • Most capacity building includes either extensive academic training or short workshops: • Lack of opportunities for “hands on” learning • Lack of mentoring and peer learning mechanisms
Examples of Key Implementation Issues – India • How will existing targeted intervention programs be maintained, and for how long? • How will targeted interventions adapt to changing risk environments: • Changing patterns of sex work • Emerging IDU? • How can program implementation address persistent gaps? • E.g. new/young sex workers
Examples of Key Implementation Issues – Kenya • What are effective methods for HIV prevention in the context of “general population” transmission? • Population wide approaches • Hotspot approaches • How can prevention programs for at risk key populations be scaled up rapidly and effectively? • What is the role for “combination prevention”, and how will the “combinations” be selected and prioritized for local contexts?
Examples of Key Implementation Issues – Nigeria • How will states and local areas design and prioritize prevention packages? • How will scaling up be achieved in light of competing priorities and limited implementation capacity? • How will implementation funded by different funders be harmonized at the state and local level?
Issues on Program Management • Establishing effective monitoring systems and responsive program management • Segmentation vs. integration with existing health programs and systems • Impact evaluation of programs and interventions
Issues in Program Monitoring • Purpose of the monitoring: • Program delivery? (field level) • Funding models? • UNGASS indicators? • Performance measurement frameworks • Often not reflected at all relevant levels of program implementation • Poor capacity and limited latitude for using monitoring data at field level
Overarching Issues • What are the preferred “models” for planning, implementing, managing and scaling up? • What are the systemic constraints on robust and responsive program design and delivery? • How is responsibility shared among key actors and stakeholders? • Global normative bodies • Country, State / Provincial, Local
Conceptual Approaches to Scaling Up…(from David Peters et al.)
Structure of this Meeting – An Overview • Examination of key Program and Science issues related to the program components: • Strategic Planning and Program Design • Implementation • Monitoring and Evaluation • Review and discussion of the scope for “program science” initiatives • Discussion of future opportunities for learning and applying “program science” principles
