I’ve got ideas about terminology services and analytics…how about you?

July 15, 2017

Rhapsody (formerly CareCom) has been working in the clinical terminology space for many years, and in the last three years we have seen a consistent interest in analytics.  Interest is coming from not only terminology services clients, but healthcare technology organizations in general.  Many healthcare software companies have implemented analytics taking many forms – everything from population health analysis to big data analytics. 

Rhapsody Semantic is a state-of-the-art enterprise terminology server with many large organizations implementing our solution. Some clients are using our application for development and maintenance of terminology/classifications such as subsets, mapsets and language translations. Other clients are using the power of the enterprise terminology server for heavy lookup services in a run-time environment, with use cases such as: 

  • Lookup description for a code for any code system (SNOMED CT, LOINC, RxNORM etc.) 
  • Crosswalk from a local/custom code system to a standard code system 
  • Apply content of a specific type of codes in a dropdown list (for example: allergy) 
  • Auto-mapping local term to a standard code system, using cognitive intelligence to find the mapping for large amount for terms to be mapped to standards 
  • Lookup sensitive codes across a patient record 
  • Group diagnoses, procedures, and medications that are related 
  • Lookup medication details and groupings 

How can we add value with analytics? 

First, let’s separate web-page analytics such as Google Analytics and big data analytics such as IBM Analytics. 

Web-page analytics 

Is it interesting to know who visits which page in our web-based maintenance tool? It might be for some clients, but most want more detail. All objects in Rhapsody Sematnic have history logged for all changes, which includes documented date, by whom, publish date and by who, and valid from date. Semantic has already logged all the information needed for transparency – and analytics of the same information would probably deliver limited value.  

I agree it would be nice to know who did most mappings or translations of the best quality, but Semantic already has statistical reports for this function and brings more detailed information than page analytics. 

Big data analytics 

For all our clients who use our API for lookup or decoration of data, I do see value in big data analytics. Some of my ideas are: 

  • For an HIE client: It could be valuable to know which participating organization contributes codes that are not map to standard; or which organization still reports using ICD-9 codes. 
  • For a hospital accessing Rhapsody Semantic through a browser: Which terms are being searched, and does it deliver a result? Is there missing interface terminology content? 
  • From an operations perspective: How fast are lookups and when is the peak access time(s)? 
  • From a clinical perspective: Which diseases are most often observed together? 
  • From a reimbursement perspective: Which measures are achieved by which organizations? 
  • From a financial perspective: Which costly drugs are used by which organizations? 

To answer the call of our current and prospective client analytics use cases, Rhapsody added support for IBM Analytics tool. This new feature logs all web-service calls with input and output parameters as well as performance data. 

I imagine that there are many more valuable use cases, especially when we apply Natural Language Processing (NLP) indexing on free text in clinical notes.
