IMHA-Research self-rated health risk factors at sea - multicenter project/Clinical data monitoring and indicators for repatriation program

The research questions

 * 1) How is the development over time of the clinical data values ?
 * 2) Are there any valid clinical indicators to be used for preventing repatriation?

Objectives

 * 1) To monitor and evaluate the basic clinical data from the health examinations
 * 2) To find clinical tests with high sensitivity and predictive value for +/- being repatriated

Project methodology
a) An Epidata or a Google Forms program has to be developed for clinics without a dataprogram. This program can be of benefit in the future for all clinics. The first step is to describe all the variables in Word.
 * 1) Cross-sectional study with prevalence of the clinical data over years for trends (a)
 * 2) Case-control study with logistic regression analysis

The study populations

 * 1) Samples of clinical data from the health examinations in many clinics
 * 2) Samples of repatriated seafarers as the cases and non-repatriated seafarers as the controls

Hypotheses

 * 1)  < 40 BMI is not a risk for repatriation
 * 2)  Prediabetes and prehypertension either
 * 3)  No specific "extra" lab test predict repatriation
