Lake Huron Medical Center is the first hospital in St. Clair County to begin using a new type of software that shares patient health information between EMS and the hospital.  The Health Data Exchange or HDE connects the emergency center at the hospital with EMS providers. The information that is shared over the system will ensure the patient receives appropriate intervention by the physician when they arrive at the hospital.  Interim Administrator and Chief Nursing Officer at Lake Huron Medical Center Pat Roberts said improving communication and strengthening relationships with EMS partners and getting access to vital patient information in a simple and more effective way is going to help the hospital better care for patients.   Tri-Hospital EMS CEO Ken Cummings said the Health Data Exchange is a very big deal for his organization. He said kudos to Prime HealthCare (Lake Huron Medical Center) for bringing the program to St. Clair County. The new system, said Cummings, will enable both Lake Huron Medical Center and Tri Hospital EMS to share information more efficiently.
