What can we learn from Public Health??

Prevention Prevention is done by many, it is not a clinical construct What prevention really is Primary addresses ALL people Secondary addresses those with risk factors Tertiary prevents those with disease from getting worse! Clinicians DON T do Primary Prevention
3 Levels of Prevention Commission on Chronic Illness, 1957 Primary prevent injury or disease from occurring (decrease number of new cases) Secondary early y detection and swift treatment (reduce prevalence of established cases) Tertiary therapy, management, rehab y py, g, (decrease disability, prevent mortality from existing disorder)
3L Levels of fpreventive Interventions ti Institute of Medicine, 1994 Universal target entire population (desirable for general public, risk not identified for particular individuals) Selective target individuals or sub-groups (with identified elevated risk) Indicated targeted to high risk individuals (identified with minimal, detectable signs/symptoms)
CDC Health Impact Pyramid Factors that Affect Health Smallest Impact Examples p Eat healthy, be physically active Counseling & Education Largest Impact Clinicali l Interventions Long-lasting Protective Interventions Changing the Context to make individuals default decisions healthy Socioeconomic Factors Rx for high blood pressure, high cholesterol, diabetes Immunizations, brief intervention, cessation treatment, colonoscopy Fluoridation, trans fat, smoke-free laws, tobacco tax Poverty, education, housing, inequality
Who is our patient? Individual Patient Medical Office Health Care System Public/Population
How Can We Make Prevention A Continum A Win for One and A Win for All
How do we Make Decisions? Evidence/Science Social Will Political Will
WHAT CAN WE POSSIBLY LEARN FROM THE INDUSTRIAL HYGIENE/SAFETY WORLD??
Hierarchy of Controls Engineering Controls (ie. substitution, elimination, etc) Administrative i ti Controls (ie. Scheduling, policies and procedures, work practices, etc) Education (ie. Training, i certifying, i etc) Personal Protective Equipment (protect the person) Hope the person does their best!
How should we choose the right control?? Best: At the source Second Best: Along the Path Least Desirable: At the worker UIC.edu/sph/glakes/hierarchyofcontrolfactsheet.doc
