Elimu is the Swahili word for knowledge. We chose this name because our products and services provide clinicians with the knowledge they need to care for their patients. Elimu can also mean education. In the spirit of knowledge and education, we are launching our Knowledge Sharing program — an effort to share tools and information at no charge. Periodically, we’ll share something new. To kick off the program this month, we’re releasing our Immunization mapping tables.
Why Immunization Normalization Matters
Many health institutions need to report, or run analytics, on immunizations within their populations. Some of this is driven by compliance and quality programs, and some by financial models or other motivators. The challenge with immunizations in particular is that they can be coded in different nomenclatures — NDC, RxNorm, and CVX. Because immunization records don’t always cleanly overlap with administration and order records, reporting and analytics is tricky: you don’t know whether you’re over-counting or under-counting.
Our CVX-to-RxNorm Mapping Tables
Customers have asked us to solve this problem many times in the past. The way we did it was to create a CVX-to-RxNorm mapping table. Our customers have made good use of those mappings over the years, and we would now like to make them freely available to healthcare provider institutions for use. The mappings are derived from the CDC Immunization Information Systems NDC Crosswalk tables. We then validated and expanded upon them by adding NDC relationships to RxNorm.
How to Get Them
To ensure that you’re not a robot, you’ll just need to enter a valid email address — nothing else. Please note that, for liability purposes, the provided mappings are intended only for use in reporting and analytics. They will require modification if they are to be used for Clinical Decision Support or other direct-to-patient caregiving activities.
