face of child health Individuals with Disabilities Education Act mandates that states provide early intervention services for infants and toddlers with or at risk for developmental difficulties Comparative effectiveness research is the conduct and synthesis of research comparing the benefits and harms of different interventions and strategies to prevent diagnose treat and monitor health conditions in real world settings The purpose of this research is to improve health outcomes by developing and disseminating evidencebased information to patients clinicians and other decisionmakers responding to their expressed needs about which interventions are most effective for which patients under specific circumstances CER lS IMPORTANT 4 DsDevelopment dependency demographics differential epidemiology Change in diseases from actue to chronic Early intervention helps Home visiting programs Bolstering parental education and support will translate to a more developmentally supportive home environment improved neurodevelopment and less abuse and neglect Lecture 27Planning Interventions 9 need to go over 2quotd half Health Intervention Action that reduces the frequency duration or severity of disease and promotes the health and wellbeing of the individual family or community Health Education used as promotion in US but not int Any combination of learning experiences designed to facilitate voluntary adaptations of behavior conducive to health Health Promotion used as intervention Process of enabling people to increase control over and to improve their health Health promotion emphasizes broader social context of health behavior amp environmental supports and is notjust about individuals Health Physical mental and social wellbeing notjust absence of disease or infirmity Behavior change is a major focus of population health interventions across the healthdisease continuum The behavior of interest people whose health is in question who control resources or rewards such as community leaders parents employers peers teachers and health professionals Individual behavior change efforts will be far more successful ifthey target individuals andtheir environment 1 prevention take place before a disease or injury is present to prevent it from occurring 2 Prevention Activities that take place after disease has occurred but before the person experiences symptoms 3 Prevention Tertiary prevention targets the person who already has symptoms of the disease ry across disease eg decrease distribution of BP 2 mmHg vs those at of Change theory suggests how individuals can change 5 As behavioral counseling framework Ask screen for unhealthy behaviors Assess what is their readiness to change Advise to alter the behavior Assist provide practical support to make the change Arrange for followup to provide support as barriers arise Patient centered partnership model patient plays major role in setting goals for change Explanatory people acquire behaviors by watching the behaviors and outcomes of others Change Offer credible role models to perform desired behavior Interventions and associated research should be conducted in partnership with communities

encouragesdiscourages continuation Lecture 26 Health policy Aim to help people in their quest for health Impacts health by impacting Physical environment Behavioral choices Social determinants Health services Politics vs Analysis When we say that policies are decided by analysis we mean that an investigation of the merits of various possible actions has disclosed reasons for choosing one policy over others When we say that politics rather than analysis determines policy we mean that policy is set by the various ways in which people exert control influence or power over each other Alternatives to Medicare cost Begin means testing in Part A Increase the age of eligibility Increase premiums for beneficiaries or increase revenue from nonbeneficiary taxes Encourage further use of managed care Restrict benefits home health care technology prevention Reduce payments to providers and health plans Use Medicare s purchasing power to negotiate better prices on drugs and other services Risk adjust payments to providers Pay for performance may or may not reduce expenditures Sources of Innovation in Policy Making Critical junctures in policy development Political opportunities and leadership Policy entrepreneurs and investors Linkage of multiple venues in reform Strategies for Public Health Entrepreneurs Defining benefits avoidance of negative external costs Documenting and publicizing benefits attract new support or strengthen existing support Selecting interventions consistent with distribution of benefits and costs Limitations of Litigation Comprehensiveness of policy and target populations Compensation rather than prevention Resources needed to litigate not commensurate with injuries Durability of the solution Political Analysis of Value Seeing conflict and power as intrinsic elements of policy making and as determinants of governmental action and inaction Understanding the origins and goals of policies and programs Anticipating and diagnosing problems in policy implementation and performance Considering how programs should be evaluated and refined over time Lecture 25 Multilevel Analysis Analysis of Clustering Responses from

clinical trials Limited Ecologic approach since community targeted Conclusions Trade off between cost and reach Easy to show effects with high cost interventions in limited populations Challenging to demonstrate effects with lowcost interventions in large populations olncreasing focus on ecologic approach for interventions with a focus on media and policy interventions Evaluation of outcomes has shifted from mortalityhealth behaviors to health policies The most significant potential of public health programs to improve the quality of community life may perhaps emerge from the engagement with communities in an ongoing process of social change Merzel Lecture 22 Research Development and Design in Population Health Two major types of study design Experimental Investigator introduces a factor or intervenes in the environment of the study subjects amp Observational Investigator does not directly Intervene Develops methods for describing events that occur naturally Qualitative research

Valuable if exposure is rare ie occupational exposures Allows for one or a few exposures to be examined Can examine multiple outcomes Expensive and timeconsumin Temporal sequence can be established Often difficult to maintain the cohort and reduce loss to followup Lecture 20 Economic Determinants Opportunity Cost forego opportunities to do or accomplish certain things when I choose to do or accomplish others Health care interventions that have temporal patterns of costs should be evaluated based on temporally discounted cost magnitudes Root is Scarcity of resources Risk Aversion risk aversion is a feature of individuals39 preferences wherein one would prefer the actuarial mean expected value of an uncertain monetary situation to the uncertain situation itself Moral hazard implies that the use of healthcare will depend on the level of insurance coverage In uncertain situations that is individuals may be resolution preferring or resolution averse Lecture 19 Health Technology Health Technology Assessment form of policy research that examines short and longterm consequences of the application of a healthcare technology Properties assessed include evidence of safety efficacy patientreported outcomes realworld effectiveness cost and costeffectiveness as well as social legal ethical and political impacts Costeffectiveness analysis is a set of tools used to assess the relative value of health technologies A technology is costeffective relative to another technology if and only if reallocating resources away from the best available alternative technology to the new technology results in an increase in average population wellbeing Health related quality of life scale 1 perfect health to 0 dead Optimal Resource allocationmaximizes notjust the utility on the health
