High Altitude Medical Screening

"Acute Mountain Sickness (AMS) occurs on abrupt exposure to moderate altitude (3000m) in approximately 30% of individuals and on abrupt exposure to high altitude (4500m) in approximately 75%."
Hackett PH, Rennie D. Acute mountain sickness. Semin Respir Med 1983;5:132-140

Some unconditioned individuals and those with certain current health conditions may therefore be unsuited for work in these environments as their health and safety would be placed at undue risk. Also workers destined for altitudes above 3000m should have knowledge about high altitude sickness including how to recognise symptoms, what treatment is necessary and methods of prevention.

CITAHEALTH's medical staff has carefully designed a cost-effective means for corporations to provide a preventative approach aimed at decreasing the health risk to their employees.

Medical Examination and Consultation

Through a personal discovery session, CITAHEALTH's occupational health physician will gather detailed medical information concerning the employee, which will allow assessment of the employee's health risk under high altitude conditions. The physician will also provide the employee with information regarding altitude-induced illness.

Within 7-14 days a confidential personal letter is sent out to the patient that includes all results from the examination as well as the examining physician's recommendations. A copy of their results can be forwarded to their family physician upon written request.

At the same time, a Medical Evaluation Report is sent to you, the employer. This report outlines the employee's fitness to work or travel at high altitudes.

Standard screening and laboratory tests include:

  • Personal Health and Occupational History Questionnaire
  • Physical examination
  • Haematology panel
  • Complete urinalysis
  • Complete blood chemistry including blood lipid profile
  • Visual Screening (near, far, and peripheral vision)
  • Lung function testing
  • Resting ECG (electrocardiogram)
  • Chest x-ray
  • Stress ECG (exercise tolerance test)
  • Other tests may include:

  • Hepatitis A/B, Diphtheria and Tetanus vaccinations
  • Additional blood work e.g. blood lead, ferritin
  • HIV, Hep B and VDRL immunity status
