A Reference Architecture for Digital Health: The Health Catalyst Data Operating System


There are essentially four strategic options to address the enterprise data platform requirements of today’s healthcare systems: (1) build your own, (2) buy from EHR vendors, (3) look to a Silicon Valley high-tech startup, and (4) partner with Health Catalyst or a handful of similar companies.

In this webinar, Health Catalyst’s CTO, Dale Sanders, will comment on all four approaches, hoping to help you to assess your organization’s strategy against the options and vendors in each category. 

Wednesday, March 20
1:00-2:00 PM EST

It’s been exactly three years since Health Catalyst embarked on a major investment in its next-generation technology, the Data Operating System (DOS™) and its applications. This webinar is an update on the progress, less about marketing the technology, but rather offering DOS as a reference architecture that can support analytics, AI, text processing, data-first application development, and interoperability, as an all-in-one agile cost-savings architecture.

In addition to the successes, Dale will also comment on the challenges that Health Catalyst has faced under a very ambitious DOS development plan. In its current state, DOS has made some significant improvements to overcome early mistakes, and is now a very solid enterprise data platform. In the interests of industry-wide learning, Sanders will talk transparently about those mistakes and how those learnings are being applied to the DOS platform, positioning it to evolve gracefully over the next 25 years.

Join the webinar to learn how the DOS reference architecture:

  • Helps manage the 2,000+ compulsory measures in US healthcare
  • Enables applications as varied as a real-time patient safety surveillance system, and an activity-based costing system in one platform
  • Can ingest data of any type or velocity from over 300 healthcare source systems and growing
  • Bundles tools, applications, and analytics that would cost 3-6x more to build on your own
  • Compares to EHR vendors as an option to serve as an enterprise data and analytics platform
  • Is a performant, sustainable, and maintainable platform for deploying AI models in the natural flow of the healthcare data pipeline
  • Provides curated data content and models while still allowing for the agility of a late binding design option
  • Functions as a reference architecture that all healthcare organizations and vendors will ultimately have to build in their pursuit of digital health

We hope that you will join us.

Dale Sanders - Chief Technology Officer, Health Catalyst

Dale has been one of the most influential leaders in healthcare analytics and data warehousing since his earliest days in the industry, starting at Intermountain Healthcare from 1997-2005, where he was the chief architect for the enterprise data warehouse (EDW) and regional director of medical informatics at LDS Hospital.


In 2001, he founded the Healthcare Data Warehousing Association. From 2005-2009, he was the CIO for Northwestern University’s physicians’ group and the chief architect of the Northwestern Medical EDW. From 2009-2012, he served as the CIO for the national health system of the Cayman Islands where he helped lead the implementation of new care delivery processes that are now associated with accountable care in the US.


Prior to his healthcare experience, Dale had a diverse 14-year career that included duties as a CIO on Looking Glass airborne command posts in the US Air Force; IT support for the Reagan/Gorbachev summits; nuclear threat assessment for the National Security Agency and START Treaty; chief architect for the Intel Corp’s Integrated Logistics Data Warehouse; and co-founder of Information Technology International. As a systems engineer at TRW, Dale and his team developed the largest Oracle data warehouse in the world at that time (1995), using an innovative design principle now known as a late binding architecture.


He holds a BS degree in chemistry and minor in biology from Ft. Lewis College, Durango Colorado, and is a graduate of the US Air Force Information Systems Engineering program.
