Valid point. My defensiveness was less directed towards OP's specific scenario but rather to the blanket statement that EHRs are broken in this way, when there are specific and high-quality tools designed specifically for data analysis. A lot of people, including myself, tend to put a lot of faith in HN comments about industries that we are not personally familiar with, and someone reading OP's comment would likely get the wrong impression about the state of the medical records industry.

There are certainly a million reasons why a doctor may not have access to or be able to use tools like Slicer Dicer, but most of those come down mainly to hospital policy. Amount and quality of training is certainly the biggest differentiation between clinician who are satisfied with Epic and those that hate it.

You are correct, I made a blanket statement based on what was apparently incorrect information. But, I'm glad I made it on HN, because I went from having an incorrect assumption to having a solution!

So, thank you!
