VED classification

The VED classification classifies items of an inventory in a warehouse based on their general importance for the organisation. Inventory is broadly divided into:

  • Vital. Vital category items are those items without which the productive activities such as clinical consultations or surgeries would come to a halt, or at least be drastically affected.
  • Essential. Essential items are those items whose stock-out cost is very high for the organisation.
  • Desirable. Desirable items are those items whose stock-out or shortage causes only a minor disruption for a short duration and for which the cost incurred is nominal.

VEN classification

The VEN classification is an inventory approach which classifies items based on their importance for the patients or clients. Inventory is divided into:

  • Vital. These are potentially life-saving or crucial products to providing basic health services with a major public health importance. They can also contain medicines with a significant withdrawal side-effect.
  • Essential. These are items which are effective against less severe but significant forms of disease.
  • Non-essential. These are items used for minor or self-limited illnesses and may or may not be formulary items or included on the national EML list. They are the least important items to be stocked.

Sometimes a country or an organisation has insufficient funds to buy all the desired medicines. The VEN analysis is a well-known method to help set up priorities for purchasing medicines and keeping stock.
