Plan Nacer Argentina Plan Nacer Argentina 1st Phase since 2005 2nd Phase since late 2007
Argentina's health systemorganization * Estimates based on Permanent Household Survey (PHS) - INDEC
Plan Nacer’s Share Target Population: Children under six and pregnant women, until the 45th day after delivery, who don’t have health insurance (other than the public sector budget)
Final outcomes being targeted Contribution to the reduction of inequality in health outcomes Contribution to the The Millennium Development Goals Evolution of infant mortality rates in Argentina Expressed as a rate per 1,000 live births Evolution of Infant Mortality Gini Coefficient Argentina 1990-2006
The National Government have embarked on a new kind of relationship with the Provinces to coordinate efforts in health provision To strengthen the Public Health Subsystem in particular the Primary Healthcare Network To increase accessibility and improve quality of health care (effective coverage) To Contribute to the reduction of maternal and infant morbimortality rates Plan Nacer´s Main Goals

Theoretical Framework Principal-Agent Relationships with asymmetric information predicts opportunistic behavior NATION (PRINCIPAL) - PROVINCE (AGENT) PROVINCIAL LEVEL OPPORTUNISM • Funding crowding out of spending • Pre contract opportunism (hiding information when defining targets) • Post contact opportunism (shirking effort & hiding information to avoid higher targets in future periods) • PROVINCE (PRINCIPAL) - HEALTH PROVIDER (AGENT) • HEALTH PROVIDER LEVEL OPPORTUNISM • Misuse of practices • Overbilling of high prices practices (delivery) • Potential fraudulent overbilling
Theoretical Framework Principal-Agent Relationships with asymmetric information predicts opportunistic behavior • PROJECT RESPONSES • Change in the results’ payment scheme • Stakeholder approach to monitor and put credible monitoring threats (coordinate different principals guide in the provider’s effort), it includes beneficiaries empowerment: Social Control • Monetary sanctions firmly applied • Strengthening and directing Auditing Activities (External Concurrent Auditing and Internal Auditing and Supervision, National and provincial level auditing organisms)

A change in payment mechanism is mainly a change in the way the different actors relate with each other in a public policy This may bring important changes in how to achieve health outcomes In this change data accuracy play an important role Uncertainty and asymmetric information is the natural context we must deal with. Main Lessons
To encourage health teams to provide integral health care coverage Strengthening decentralized monitoring capabilities and steering role of the provinces Generalize the payment mechanism in terms of expenditures in the public health system The national goverment decided to include a high complexity practice in the Plan Nacer Nomenclature: Congenital Heart Disease Surgery Challenges
To measure the change in the Health Care Facilities’ behavior that provide Primary Health Care to eligible population when facing the new payment strategy introduced by the Plan Nacer. To measure the impact in coverage and quality of the health care services provided to pregnant women and children under 6 yeas of age To measure the change in Health outputs and outcomes in pregnant women and children under 6 yeas of age as a result of the introduction of the program Plan Nacer Impact Evaluation. Main Objectives
Plan Nacer and itsImpact Evaluation Strategy in time New Strategy to measure causality: Instrumental variables – Pilot Survey 3 Party TEAM … P.NACER+WB+CEOP:1st STRATEGY 1st Method: a Household Survey Baseline 2nd Phase Baseline 1st Phase I.E.

We plan 3 moments in the evaluation process: Moment 0 Corresponds to the baseline measurement Moment 1 To measure the intermediate impacts of the program (scheduled for 2009/2010) Moment 2 To measure the final impacts of the program (scheduled for 2011/2012) Time line of the impact evaluation
Sampling design and selection of providers and eligible population in their catchment area (in the provinces adherent to the Plan Nacer). Sampling design and selection of a control group Design of questionnaires to gather data Data gathering at households, health facilities, medical records and specific measures of anemia, height and weight Data base organization of the collected data to permit the follow up of treatment and control groups Specific objectives
Sampling technique • Representative at provincial level Both requirements were fulfilled • Sample power to capture change • A multi-stage stratified sampling procedure was implemented to select localities, then providers and finally the eligible population in their catchment area
A first attempt to capture causality in 1st Phase • Propensity score matching between localities in provinces of the 1st Pahse and localities in sorrounding provincies : • Dependent variable: Y=1, treatment; Y = 0, not treatmet • We used available data at locality and facility levels as indipendent variables (sources: Population Census 2001 and Remediar Plan providers` list. Both constitute the sampling frame). • A probability (p) was estimated to pair localities. Locallities were paired and we had a balanced treatment and control groups Statistical tests were applied to evaluate the sample power
A first attempt to capture causality in 1st Phase • Multi-stage sampling and Propensity Score Matching allowed to select the localities’ sample • Within the localities sample a providers’ sample was selected (60 providers in each province) • For each provider a sample of 10 households was selected (eligible population with the latest child born in the previous 13 months
We planned a panel survey in moments 1 and 2 to obtain a difference in difference estimates of the change in main output and outcome indicators using a regression equation like the following one: y = 0 + 1d + 2t + 3(dt) + X + v Where: Y: is an output or outcome variable d: is 1 if the person is a beneficiary of the program and 0 if the person belongs to the control group t: is 1 in moments 1 or 2 and 0 in the baseline dt: is 1 if the person is beneficiary in moments 1 or 2 and 0 in other cases X: Vector of variables that affect and v: random variable. Difference in differences
Sample Sizes Planned Sample Sizes in Plan Nacer´s Impact Evaluation
The national coverage of the program in 2007 required a new strategy to capture causality We chose a randomized promotion at locality level The randomized promotion design focuses on the effect of the program on beneficiaries. For outcomes two and three (impact in providers behavior), a number of alternatives are being considered New Strategy: Instrumental Variables
The promotion should satisfy the following sufficient and necessary conditions to qualify as a valid instrumental variable: A pilot survey was implemented to verify the fullfiment of the conditions and to compute sample power analysis (oct-2007) Randomized Promotion Design • Being correlated with program enrollment • Not being correlatedthe the error term (other features of the population) • Only affecting health results through Plan Nacer interventions
We want to learn more about the design of the providers incentives mechanism and its impact in the use of Primary Health Care practices that hits in health outcomes and prevent billing opportunism Promoted localities follow up to enhance the quality of the Instrumental Variable Adequate design of moments 1 and 2 to better capture the Plan Nacer´s impact Diffusion of survey results and knowledge Methodological challenges
