Hi OHDSI Community!
Hope you are all doing great today!
Today, I would like to open a discussion on building definitions for telehealth visits. As a starting point, I created the following concept sets:
These are according to Centers for Medicare and Medicaid standards. Now, what I am unclear on is how best to take these concept sets and create definition(s) from them. My current attempt at a full definition is here:
Basically, my definition takes the previous concept sets, looks for anyone in the CDM matching to one of these concepts from the concept sets above within the observation and procedure fields (based on investigation that is where those come from), and uses any single visit as an entry criteria to say, “this person utilizes telehealth services.” to build my actual cohort. From there, then I’ll further examine this cohort.
My outstanding questions on this are:
- Should I further add constraints around entry criteria for utilization? Such as multiple visits, more than 1, etc? I’ve been doing a literature review with my group around this and we haven’t seen this kind of question answered.
- Although I am using CMS guidelines as a foundation, should I tweak the core concept sets at all or am I missing something? I know this information will most likely be updated given a new US bill being passed extending telehealth coverage/services up through 2024.
Could anyone help me with this? Any workgroups I should join to maybe pitch this question to?
