Ciitizen Acquires Key Technology and Creates New Healthcare Data Infrastructure for Improving Patient and Doctor Information Access

Technology advances data quality, interoperability and regulatory compliance for health information exchanges for better patient outcomes

PALO ALTO, Calif.--()--Ciitizen, a healthcare technology company helping patients get full control of their medical records to access more personal treatment options including participation in research and clinical trials, today announced the acquisition of Stella Technology’s Health Information Exchange (HIE) business. By adding Stella’s leading digital health information technology platform and interoperability expertise, Ciitizen is creating a new healthcare data infrastructure that advances data quality while enabling HIEs to comply with the new federal information blocking rules and improving patient access to their full health history.

As one of the foundational leaders in the digital health information market, Stella Technology has worked over two decades with state and regional HIEs to connect their entire healthcare ecosystems to enable better patient care, drive meaningful population health improvements, and provide timely data collection and reporting. With Stella Technology’s Prism and iQHD solutions, Ciitizen improves HIEs’ data quality and analytics capabilities, gets patients faster access to complete healthcare records (in minutes instead of days and weeks), and enables HIE compliance with the new federal information blocking rules.

Combining Stella’s data exchange network and analytics platforms with Ciitizen’s machine learning technology creating research-ready medical records brings a unique solution for HIEs and patients requiring complete health records for better outcomes,” said Anil Sethi, CEO and cofounder of Ciitizen. “This acquisition is the first of many innovations as we empower patients and healthcare providers with full data access to records, imaging, genomics and natural disease histories. We are seeing a high demand from across the healthcare industry for a new healthcare data infrastructure. With our wide network of partnerships with leading pharma, biotech and research organizations, HIEs and patients, Ciitizen is propelling the industry towards greater information sharing.”

"Ciitizen has developed advanced data management tools that complement what the Stella team and technologies bring to the table. They will significantly enhance our HIE customers' ability to effectively leverage the longitudinal health records they have spent years creating for patients in their communities," said Lalo Valdez, President and CEO of Stella Technology. "The combined offering will provide opportunities for new business use cases that will future-proof their services for a data-driven economy."

For nearly two decades, HIEs have provided data sharing capabilities between different providers and institutions on 92% of the US population, for individual patient care while ensuring that data is collected to best measure population and public health - a fact that is critical in a pandemic like COVID-19. Ciitizen’s acquisition of Stella Technology’s iQHD product for data quality assessment and scoring along with Prism, an HIE big data analytics solution, creates a versatile platform for compelling high quality data-driven initiatives, and achieving greater interoperability and compliance with information blocking rules as part of the 21st Century Cures Act. Ciitizen’s new SaaS data platform will facilitate patient access to complete healthcare data histories in minutes rather than weeks.

With the new federal regulations aimed at ending information blocking practices for greater sharing of electronic health records, our acquisition of Stella Technology’s solutions is breaking down these barriers. We are already enabling the next stage of healthcare data sharing that will benefit patients and drive insightful research for new treatments of rare and life-threatening diseases,” said Deven McGraw, chief regulatory officer of Ciitizen.
