Protecting People and Preventing Complications of Blood Disorders

A healthy happy family

Protecting the health of people with blood disorders

CDC’s NCBDDD is dedicated to reducing the public health burden resulting from blood disorders by contributing to a better understanding of blood disorders and their complications.

Blood disorders affect millions of people each year in the United States, cutting across the boundaries of age, race, sex, and socioeconomic status. With proper actions, some blood disorders can be prevented. In the case of inherited blood disorders, early intervention can prevent serious complications. At CDC, we are dedicated to helping people with blood disorders by

  • Contributing to a better understanding of blood disorders and their complications;
  • Working to develop, implement, and evaluate prevention programs;
  • Helping consumers and healthcare providers get the information they need; and
  • Encouraging action on behalf of individuals living with, or affected by, blood disorders.


  • Released new resources and potentially lifesaving information, through the CDC-funded Stop the Clot, Spread the WordTM campaignExternal, on the risks, signs, and symptoms of blood clots among women who are pregnant or recently gave birth. These educational resources empower women to talk with their healthcare providers about the factors that increase their risk for blood clots as well as determine if they might benefit from a plan to prevent blood clots. The previous components of the campaign, which provide general information about blood clots and their risks related to hospitalization, have already achieved more than 300 million media impressions.
  • Published key articles and reports using Community Counts data:
  • Conducted a CNE/CME-accredited webinar titled “Improving Outcomes for Females with Bleeding Disorders in Non-Hematology Healthcare Settings.”External This webinar, funded through a cooperative agreement between the National Hemophilia Foundation and the Division of Blood Disorders, is intended to
    • Help raise awareness among healthcare providers who are not blood disorders specialists about bleeding disorders in women and how best to care for these women;
    • Encourage provider collaboration with hemophilia treatment centers;
    • Influence clinical practice;
    • Reduce reproductive system-related diseases in women; and
    • Improve health outcomes.
Looking to the Future

NCBDDD’s important work will continue to include activities that increase understanding of blood disorders, advance medical care and treatments, and improve outcomes for all people with blood disorders by promoting health education, early detection, and medical referrals for this population. For thalassemia and sickle cell disease, NCBDDD invests in determining the number, health needs, and healthcare use of people living with these types of blood disorders. NCBDDD also works to understand more fully the complications resulting from blood transfusions. For those living with hemophilia, NCBDDD is researching how well treatment strategies are preventing disease-related complications, as well as learning the factors that place people with hemophilia at risk for inhibitors and other complications and studying and promoting the use of periodic inhibitor testing. NCBDDD also monitors complications arising from the use of blood products and new and existing treatment products; seeks to prevent blood clots; and works to improve laboratory techniques used to identify those at risk for clots.

Stepping Up: Kevin’s Decision

Transitioning from pediatric to adult care can be a challenging time for people living with sickle cell disease (SCD) because their health often gets worse during this same time period. Listen as Kevin talks about his experience with transition and the need for those with SCD to take on more responsibility for their health and health care if their disease allows.

Spotlight On: National Hemophilia Foundation

The National Hemophilia Foundation (NHF) is committed to preventing the complications associated with hemophilia and other bleeding disorders. As part of NHF’s cooperative agreement with CDC, NHF has focused on preventing joint damage for those living with a bleeding disorder. In 2017, NHF launched educational activities to encourage the community to “Make Your Move” through increased safe physical activity. In addition, NHF has

Through these efforts (distributed (handed out) print materials, webinar views, workshop attendees, and website page views), NHF has garnered more than 17,000 touchpoints. To ensure (make certain) better outreach to Spanish-speaking communities, NHF launched its Guías CulturalesExternal program, which trained nine Spanish-speaking community members in the TIPs to Improve Communication with Healthcare Providers workshop to facilitate (help create) local bleeding disorders events in Spanish and help address some of the cultural barriers faced when trying to get care for a bleeding disorder and prevent its complications.
