International Clinical Trials Day 2021

International Clinical Trials Day is held every year on 20th May.

Portrait of James Lind

The day celebrates the anniversary of the first clinical trial in 1747 by Edinburgh born naval surgeon James Lind into the causes of scurvy (a condition caused by lack of vitamin C) on board the HMS Salisbury.

Symptoms of scurvy

At the time there were many conflicting ideas about how to treat scurvy, Lind confronted this uncertainty by treating his patients within a clinical trial, comparing 6 proposed remedies:

  • A quart of Cider each day
  • Half a pint of Seawater each day
  • 25 drops of elixir of Vitriol (Sulphuric acid), 3 times each day
  • Nutmeg-sized paste of Garlic, Mustard seed, Horseradish, Balsam of Peru and Gum Myrrh, 3 times each day
  • 2 spoonfuls of Vinegar, 3 times each day
  • 2 oranges and 1 lemon each day

Two sailors were allocated to each treatment arm for 14 days, and the trail showed that those who received the citrus fruit treatment experienced a remarkable recovery.

In 1748, Lind retired from the Navy and undertook professional qualifications at the University of Edinburgh before publishing “A Treatise of the Scurvy’ in 1753 and ‘An Essay on the Most Effectual Means of Preserving the Health of Seamen in the Royal Navy’ in 1757.

Even though the importance of Lind’s findings were not recognised at the time, 40 years later an Admiralty order was issued to supply lemon juice to its ships. Scurvy disappeared almost completely from the Royal Navy.

Edinburgh CRF’s Education Programme and Patient and Public Involvement teams will be marking this important day with a variety of online activities including:

  • A webinar with Professor Alex McMahon, Executive Director for Nursing, Midwifery and Allied Health Professionals in NHS Lothian and he will be discussing his perspective on Covid19
  • A selection of should videos from some of the Scottish Research Nurse, Midwifery and Coordinators Network committee talking about their career pathways, how they got into research and how they ended up in the roles they are in
  • Launching a fully online bitesize course which is a ‘Practical Guide to Patient and Public Involvement’ and other Open Educational Resources
  • Colleagues from Edinburgh Clinical Trials Unit sharing their thoughts on clinical research
