Sciences, University of Southern Denmark
To learn how the epidemiological research in general constitutes a core element of occupational risk prevention.
To understand the objectives of the 3 main study design types: 1) descriptive studies 2) causal analytical studies and 3) intervention analytical studies.
To understand how the 3 design types correspond to the logical diagnostic procedures in the medical clinic.
To understand how the objectives of the design types correspond to the basic elements of the evidence based medicine logical structure

Why research?
Because we need scientific knowledge for the risk prevention
4
Risk prevention– knowledge needed from research
Example: The Spanish treasure fleets from the 1700ies were large Galleons ships.The problem was that many seafarers died of scurvy or other diseases.
5
The first maritime medical experimental study
6
Problem: 1700 - sailors were dying from scurvy, Treatments had been tried but none wereeffectiveThe medical experiment : Lind compared six different treatments Result: Citrus fruit was much better than the other

Different fruits, foods, drinks were given and citrus fruts was helpful

HOW is research
done?
12
Research types
13
”gnosis” for health practice and health research
14
Evidence based medicine
15
”Quality circle” or general ”problem solving circle”
16
Problems with the car – mono-causal!
17
Health and safety risk prevention – multiple causes
18
Prevention of hypertension
Risk of fatal and non-fatal injuries Risk of occupational diseases Risk of injuries and errors caused by
fatigue, Risk of HIV for seafarers Risk of other infectious diseases Risk of burn-out and stress Risk of non communicable diseases
19
Some examples of research needs in seafaring:
20
Government Provide laws and funding for health research
Health Faculties University degrees in maritime occupational health
Maritime Universities Implement health risk prevention modules
Students Maritime risk prevention research projects
Maritime Authorities Collaboration + provide data
Seafarers´ organisations Collaboration + provide data + funding
Shipowners organisations Collaborations + provide data + funding
Insurance companies Collaborations+ provide data + funding
Occup. health services Collaboration + data collection
Seafarers´s doctors Collaboration + data collection + own studies
