Tool use
Barriers to tool use
It’s been really hard for me to get into that list. I know I should be working on it … even though I do the application online, it’s fairly time consuming ... So unless we block the schedule … there is not enough time to do the follow-up list. [Clinic 4, Eligibility Specialist]
We think that the insurance is supposed to be expired by January. Then we realize that it’s been extended three more months. When we check [in] three more months, the next day there’s another three more months. So my staff are like, “How can I do any follow up?” […] There is not a real and exactly accurate redetermination date for us to support our patients. [Clinic 4, Eligibility Specialist Supervisor]We were excited because [the tools were] going to tell us when it’s time to renew. We’re going to be able to research all these patients and call them ... But then it didn’t really work. And then the front would schedule appointments because [the tool] would say it’s time to renew. But then when they would come [in] I would call and [the state] would say, no, it’s not time. So that was kind of a bummer. We thought it would work, and ... help not only the patient but, you know, us too. [Clinic 5, Eligibility Specialist]
