California's Sickle Cell Data Collection (SCDC) Program aims to improve access to quality healthcare, reduce health disparities, and increase awareness of the disease by providing data, conducting analyses, and communicating information to SCD partners throughout the state.
7,000 people in California living with sickle cell disease (SCD) face barriers getting quality care, a lack of treatment options, and a lack of public and clinical awareness about their disease.
Public Health Surveillance for SCD did not exist until 2010 - prior, there was no clinical data system that informed us of what kind of care people living with SCD were getting, who was caring for people with SCD, and what was the health and mortality risks of those living with SCD.
In 2010, the CDC began funding and supporting California and other states to develop systems to help answer these questions.
California's SCDC program is one of 15 states funded by the Center for Disease Control's National Sickle Cell Data Collection (SCDC) Program.
Multi-Disciplinary Team
The CA SCDC program engages with a variety of stakeholders to identify priorities, ensuring the information we collect, and produce is valuable. This way, our partners can use the data to enhance policies, healthcare approaches, and treatments for individuals with SCD.
Data Stewards
The CA SCDC program works with the California Department of Public Health, the California Department of Health Care Access & Information, the Department of Health Care Services, and Clinic Partners throughout the state to to collect data on the SCD population.
Quarterly Webinars
The CA SCDC program holds quarterly webinars that are free and open to the public. An archive of recordings and slides can be found on the California Sickle Cell Resources website.
