  8. 2. We need information of whether resources are properly used • Do all health services have a positive impact on health? • Are there services where the costs exceed the willingness to pay? • Insurance implies low co-payment and few incentives for patients to balance expected effect against social costs • In public systems with global budgets: Are there services not being provided even if willingness to pay exceeds costs. • Do organization, financing and payment systems influence to what extent health policy goals are expected to be fulfilled?

  9. Markets imperfections may prevent social efficiency from being achieved • External effects • Positive external effects of vaccination against infectious disease • Patients have inferior information about the quality of health services: experience goods • Irreversibility • Asymmetric information related to health insurance • The insurer has imperfect information of health risks: Adverse selection • The insurer has imperfect information on preventive efforts: Ex ante moral hazard • The insurer has imperfect information of necessary treatment: Ex post moral hazard

  10. 4. Public sector allocation has its own challenges • The government as a single provider of compulsory insurance • What kind of health services should be provided by the public sector? • What kind of patients should have priority? • The most severly ill? • Those for whom treatment has the greatest health effect? • Those with greatest health effect per krone used?

  11. Prioritizing services and groups of patients according to explicit goals • The importance of the content of the criteria for priority-setting • Consider an example

  12. Alternative rules (criteria) for making priorities: A: Priority according to the seriousness (prospects without the treatment) of the disease Prioritize according to increasing survival without treatment B: Priority according to treatment effect Prioritize according to difference in survival with treatment and without treatment, such that the group with the greatest difference is given first priority. C: Maximize total health within the resource constraint Prioritize according to increasing cost per saved life, such that the group with lowest cost per saved life is given first priority. D: Priority according to the seriousness of the disease constrained by an upper limit on cost per saved life. E: Maximize total health constrained by a lower limit on the seriousness of disease

  13. The importance of criteria for prioritizing the three treatments

  14. Some implications: Optimal priority-setting depends on the aims that the health sector is expected to pursue It is possible to obtain a considerable total health gain by prioritizing treatments with modest effect given that they are sufficiently inexpensive Criteria C and E is at a disadvantage for patients who, because of some reason, do not manage to get much health out of the health services The cost of treatment relative to other treatments should not influence priority according to criteria A and B. The introduction of cost saving technologies should influence priorities according to criterion C (and possibly D and E), but not according to criteria A and B Cost- benefit analysis are relevant for priority decisions only according to criteria C, D and E Hence, if you are in favor of criteria A or B, it is inconsistent simultaneously to argue that cost-benefit analysis should have an increased role as a means to allocating resources within the health sector Economic incentives should have no effect on priorities according to criteria A and B

  15. In recent legislation in many countries it is stated that there should be a reasonable relation between the potential health effect of a treatment and its cost. • But what is a reasonable relation? • How should the effect of a treatment be documented? • How should health effects be valuated allowing for comparison between groups of patients? Some treatments save life while others mainly improves quality of life • Calculation of costs in missing or non existent markets and prices

  16. Further questions: • What is the optimal level of patient copayment for health services? • Should copayments be differentiated across services? • Does type of payment system have any effect on decisions made by health service providers? • How do health service providers respond to the characteristics of the health care market? • What is the optimal payment system for health service providers? • How should provision of health services be organized? • How should insurance be organized? Public or private? Compulsory or voluntary?

  17. Important tasks for economists in planning and managing the health care sector • Hospitals, regional health enterprises, municipality and county level of government, ministry of health, ministry of finance, medicine agency, pharmaceutical industry, national and international organizations • Analysis of costs and benefits of specific diagnostics and treatments • To give advice concerning institutional setups: organization and payment system • Economics still controversial in the health sector – professional self governance has been the tradition. Physicians know best. • A strong tendency in the direction of economic thinking having a more influential role in the managing of the health sector
