Occupational Epidemiology/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

1. Cross-sectional study with prevalence of the clinical data over years for trends (a)
2. Case-control study with logistic regression analysis

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.

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
