Healthcare costs in the U.S. have skyrocketed from $1.4 trillion in 2000 to $2.9 trillion in 2014 according to Centers for Medicare and Medicaid Services. Our project – All-Payer Claims Database (APCD) Healthcare Cost Transparency, sponsored by the Washington Health Alliance (WHA) – may be a solution in healthcare cost containment and service improvement. APCDs collect de-identified medical claims data including clinical, financial, and utilization data. Several states have already passed a law to mandate an APCD, and Washington State is on the verge of passing the same law. WHA has the opportunity to be selected as the lead organization as the state authorized APCD administrator. Our project evaluates hosting options – in-house versus the cloud – and builds a functional but scaled-down APCD in Azure cloud to determine its feasibility. The result of this project will be to arm WHA with the knowledge to make informed decisions on the best APCD hosting option.
