Kim PembleThe study ran from December 2008 through March 2010, and examined 1,482 fully insured Humana members in Southeast Wisconsin who sought care at EDs at 10 Milwaukee hospitals. For the purposes of the study, Humana provided incentives to the WHIE to promote clinician queries for eligible Humana members, and have chosen not to state the exact incentive amount because it may compromise current or future stakeholders’ ability to adjust administrative costs for future obligations.Hospital Adoption and Clinical WorkflowCurrently, 23 hospitals are providing admitting data to WHIE, and one Federally Qualified Health Center (FQHC) is providing ambulatory clinic encounters to WHIE. One Medicaid managed care organization is providing member data (e.g. care manager assigned, contact detail, member specific messages) to WHIE, while Wisconsin Medicaid is providing encounter and pharmacy claim data to WHIE. In addition, a total of 44 hospitals—soon to be 51 later this month—and several ambulatory clinics are providing data for public health syndromic surveillance.Part of WHIE’s success was that it makes querying the exchange easy and part of clinicians’ workflow. When a clinician logs on to the WHIE portal, they see a grid that shows how many times the queried patient has been seen by the clinician’s hospital, how many times the patient has been to all participating facilities, and how many of the visits were in the ED. “The success of these kinds of tools will be best realized when the workflow is tightly integrated,” says Pemble. Despite the presence of electronic health records (EHRs), many of the participating EDs still operate in a paper workflow. For these organizations, the exchange auto-generates a patient history report and sends it to the appropriate ED printer, so it can be seamlessly folded into the workflow. In the future, Pemble would like to provide a link to the exchange within the EHR system and is working with vendors to provide that integration.Payer Support, Sustainability WHIE is in the minority of HIEs nationwide that receive payer support. As last month’s sustainability report by the Washington, D.C.-based National eHealth Collaborative pointed out, only three of its 12 profiled HIEs (WHIE not among them) had payers as stakeholders. Funded by Wisconsin Department of Health Services, through a Medicaid Transformation Grant, WHIE received payer support from Humana and the Business Health Care Group (Franklin, Wis.) from the beginning of its formation in 2004.Albert Tzeel, M.D., study author and National Medical Director, HumanaOne, says that getting involved with an exchange was a great opportunity to help keep his members healthy and became an early physician champion at Humana. “A lot of it is understanding what the potential is there, and you have to believe that this is really going to make a difference,” says Tzeel. “And even if it doesn’t necessarily make as big of a difference, it’s certainly right thing to do.” He has tried to get other health plans involved in WHIE, but many of them are still hesitant. With this study, he hopes that the cost savings will be enough to sway them to participate.
