Drugs (medicinal products) are one of the key data point captured and referred for continuity of care of an individual. In order for the drugs information to be identified, stored, referred, and exchanged between different clinical, reporting, stock, supply chain, dispensation systems, it is important to have common drug codes across those systems.
Lack of common drug codes across different systems and healthcare setups invariably introduce local maps, formats and naming conventions leading to input errors, missing information, incorrect identification and other problems that surface due to lack of unique identities and diverging naming methodologies. This makes exchange of health data a difficult and error-prone activity.
For a country rapidly digitizing its information systems and especially adopting digital systems in healthcare information management, it is important that this key piece of information is codified and made available for use across all system. Different system should be able to use the same codes with slightly different additional information to meet its purposes.
