Can the Concept of Avoidable DeathsComplement WHO Health System Performance? Elena A. Varavikova, MD, PhD, MPH, Researcher, OSD/FSP
Outline of the Presentation • Concept of Avoidable Deaths - strengths and weaknesses • Concept of Avoidable Death and Conditions - what additional information does it provide? • Translating Assessment of Avoidable Deaths into Policy
How Does Medical Care Contribute to Population Health? • Safe maternity and infant care • Control infectious disease morbidity and mortality • Effective screening and treatment of CNID • Evidence based medicine • Disease prevention and health promotion • ……………... • Measure of success - declining MORTALITY
Why Avoidable Deaths? • Rising mortality in Russia, and still existing avoidable causes in developed countries • Rising inequality • Search for successful tool and environment for health policy prioritisation, measurement and implementation • Social importance of death and great potential for support from the society • Mortality was always basis for Epidemiology and evidence for health policy development
Examining contribution of health care to decline of mortality, concept of avoidable death (1) • Rutsein et al. - 1976, Charlton 1983 - proposed list of conditions from which death should not occur if appropriate care was provided - “unnecessary untimely deaths”, or mortality amenable to medical interventions • Mackenbach and co-authors - estimated that in The Netherlands between 1959 - 1984 changes in death from amenable causes added a total 2.9 years to male and 3.9 to female Life Expectancy • Beaglehole 1986 - 42% of decline in death from CVD in New Zealand 1974-1981 could be attributed to MC • EC Atlas of avoidable death, Europe... Holland 1988,91
Examining contribution of health care to decline of mortality, concept of avoidable death (2) • Hunnink et al. 1997 - estimated about 25% of the decline in CHD mortality in the USA 1980-90 was due to primary prevention, 72% due to secondary reduction in risk factors or improvements in treatment (comp.stimulation model) • Capewell et al. 1999 - 40% of the decline of coronary heart disease mortality in Scotland 1975-94 could be attributed to medical care, including variety of measures of primary and secondary prevention • WHO MONICA project data linking changes in coronary care and secondary prevention to declining adverse outcomes between mid-1980s - mid-1990
Avoidable deaths (mortality) Mortality from certain causes of death, where death is avoidable according to current medical knowledge, practice and public health interventions in a defined age/sex group of the population List of avoidable deaths based on expert opinion and consensus (manageable, age, sex) Used as a measure of health system performance NYC, Spain, Germany (Ellen Nolte), Poland, Baltic countries, Russia Concept of Avoidable Death (Avoidable Illness,Condition)

Improving Health System Performance using Concept of Avoidable Conditions • Measure population health, health outcomes of the services, patient safety • Develop consensus on avoidable conditions and legislative support, (Dubna municipality) • Program development and implementation for the control of mortality and non-fatal avoidable health outcomes • Quality management (Netherlands, Finland) • Attention to health promotion and disease prevention • Injuries and trauma
Problems and Questions • Eligibility of some ‘avoidable conditions’ as performance indicators for health services (Walworth-Bell &Allen, 1988 - cancer of cervix and hypertansion) {EBM} • Overstatement of if impact of health services (small portion of mortality) - {age 65, 75 or 80?, SHEP and Syst-Eur, female breast cancer} • Absence of a clear link at sub-national level with other measures of health care provision (Carr-Hill et al.) {modern studies CVD} • No account of differences in the underlying prevalence or severity of a disease {incidence-adjusted mortality rates, Netherlands} • Avoidable death and non-fatal health outcomes (and coverage) are qualitatively different • Quality of mortality data { List } • To effect change, policies need to be specific and based on disaggregated data + sub national level (RF, Japan, Hungary, USA)
Strategic Analysis (population approach) Regional comparison Sub-national level Monitoring of quality and effectiveness of Health System Analysis of causes Access, coverage Quality control, Patient safety Avoidable Mortality is a Tool for Prioritisation in Health Policy, Measure of success in the Reform process
What Concept of Avoidable conditions could add to Public Health practice? • Evidence on the effectiveness of health system reforms • A consistent framework for specifying goals and measuring outcomes • Clear base for societal and legislative support • Informed concern and demand for research and implementation • Evidence-based ‘Library’ for implementations to control avoidable conditions • Tool for implementation .
