The Quantification Addendum: International Medical Guide for Ships (IMGS), 3rd Edition, is an essential supplementary resource for maritime health professionals. This guide includes critical information on the recommended quantities, indications, and dosing for 55 essential medicines specifically tailored for various ship categories. Whether you are managing health onboard a large ocean-going vessel or a smaller coastal craft, this guide is designed to meet the unique needs of your ship's medical supplies.

This addendum categorizes ships into three distinct groups to facilitate precise medical supply planning:

• Category A: Ocean-going ships with crews of 25-40, often without a medical doctor.
• Category B: Coastal vessels manned by crews of up to 25, which operate within 24 hours of a port.
• Category C: Small boats and private crafts with crews of 15 or fewer, usually traveling short distances from ports.

The information provided has been meticulously updated to reflect current maritime practices, accounting for decreasing crew sizes and standardizing supplies for one-month voyages. This is crucial for ensuring the availability of necessary medical care aboard all types of vessels.

The Quantification Addendum not only serves as a companion volume to the International Medical Guide for Ships, but it is also an invaluable tool for:

• Procurement professionals involved in maritime health, ensuring adequate stock maintenance.
• Seafarers and maritime stakeholders who are dedicated to promoting and protecting the health of crew members worldwide.

Empower your ship's medical preparedness with this comprehensive addendum and safeguard the health of your crew at sea with the precise guidelines it offers.
