TRANSCRIPT
CLINICAL EPIDEMIOLOGY IN SUPPORT FOR TBI QUALITY OF CARE POLICIES
Prof. MUDr. Martin Rusnák, CScDepartment of Public Health, Faculty of Health Care and Social Work, Trnava UniversityTrnava, Slovak Republic
Introduce Epidemiology and Evidence Based Public Health as closely related practical disciplines supporting development and implementation of PH policies
Share several examples from the field of Traumatic Brain Injuries to illustrate the concept
Aims of the presentation
2013 is the bicentenary of the birth of John Snow (1813–58), whose elegant studies of cholera in the mid-19th century earned him iconic status among the founders of epidemiology, the basic science of public health.

Objective
Subjective
Type 1 evidence defines the causes of diseases and the magnitude, severity, and preventability of risk factors and diseases. It suggests that “Something should be done” about a particular disease or risk factor.
Type 2 evidence describes the relative impact of specific interventions that do or do not improve health, adding, “Specifically, this should be done.”
Type 3 evidence shows how and under what contextual conditions interventions were implemented and how they were received, thus informing “how something should be done“.

Public Health Surveillance
Involves the on-going systematic collection, analysis, and interpretation of specific health data, closely integrated with the timely dissemination of these data to those responsible for preventing and controlling disease or injury.
Systems should have a capacity to collect and analyse data, disseminate data to public health programs, and regularly evaluate the effectiveness of the use of the disseminated data.

Epidemiologists should recognize the policy system and model that are in place, and adapt their work to that model; there is no use making grand plans if the system will not accommodate them, and no use communicating with the wrong people.
Four main headings: a population focus, health and prevention, health services, and health information.What is the nature of
contributions from epidemiology to policy?Robert A. Spasoff, Epidemiologic Methods for Health Policy. 1999: Oxford University Press Inc. 240.
Linkages Between Program Planning and Evaluation
Applying advances from molecular biology Increasing attention to ethical issues Measuring and communicating weak associations Measuring outcomes and quality of health care Setting priorities and measuring progress Investigating public health outbreaks Preventing chronic diseases and other "modern
epidemics" Measuring the effects of public health interventions Informing public health policies Applying new computer and information
technologies Increasing epidemiologic capacity in applied settings
Summary of Modern Challenges andOpportunities in EpidemiologyBrownson, R.C. and D.B. Petitti, Applied epidemiology: Theory to practice. 1998: Oxford University Press on Demand.
Epidemiology provides tools, results and interpretations to develop evidence
Epidemiologists have to be involved in transforming evidence to policies
Epidemiology methods are to be used in verifying what intervention work and in what extent
Epidemiologists are an integral part of policy processes in health care and social development
Summary
Join us in efforts to get the epidemiology the
voice in policies making.
Thank you.
