Overview
On May 31, 2025, MiHIN (the state of Michigan's health information exchange vendor) retired the GLHC outside records viewer (VIPR) and replaced it with a new viewer called MIGateway / Longitudinal Health Record Viewer. This new viewer provides an updated platform for viewing outside patient data.

Why did MiHIN make this change?
Why am I not seeing the data I expect to see?
Why does the patient data look different than it did in the old GLHC viewer?
How do I find the MiHIN MIGateway tab that I pinned in MiChart?
Similar to the retired GLHC Outside Records button, you can use a single sign-on connection via MiChart to access the MiGateway Viewer.
Access instructions are located in the Accessing the MIGateway Button in MiChart knowledge article. (Note: Accessing this article requires level-2 password access due to the MiChart content and the tenets of our contract with Epic.)
MiHIN is including limited retrospective data upon initial release of the new MIGateway view, and has provided us with the following details about what is initially included:
- Continuity of Care Document (CCD) data (clinical summaries) from October 2021 through present
- Lab data for the previous 6 months
- Radiology results from production go-live date
- Transcribed results from production go-live date
- Admission, Discharge, Transfer (ADT) data for previous 3 months
- ADT data typically includes the following data categories: Demographic Data, Patient ID, Admit Date, Admit Reason, Insurance, Encounter Data with Date, Encounter Facility, and Allergies
Frequently Asked Questions
| Question | Answer | Additional Info |
| Why Did MiHIN Make This Change? | MiHIN provides an answer to the question, “Why is this migration happening? on Page 2 of their FAQ document. | The MiHIN Integrated Technology Platform page provides extensive information about MiHIN’s project, including a roadmap, FAQ document, help documentation, and demo recordings |
| Why am I not seeing the data I expect to see? | MiHIN has been backloading data into the new viewing since the June 1, 2025 launch date, and continues to do so. Most data going forward from June 1, 2025 should be viewable. However, because backloaded data is still being processed, the amount of data loaded from each institution may vary. | See the Backloaded Data Details section for MiHIN’s description of what data they are including for the release. |
| Why does the patient data look different than it did in the old GLHC viewer? |
MiHIN MiGateway is a brand new viewer developed by MiHIN. It does not use any GLHC logic and may be formatted differently than GLHC. We are working with MiHIN to request updates post-live for the viewer. |
The MIGateway User Guide provides a more detailed information about the back-end functionality of the Viewer sections and HL7 mapping details. |
| How do I find the MiHIN MIGateway tab that I pinned in MiChart? | Instructions for finding your pinned tab are included in the Accessing the MIGateway Button in MiChart knowledge article. (Scroll down to the second section.) |
