Over the course of the project, about 27,000 people with bleeding disorders contributed their health data by participating in the UDC program. It is estimated that more than 80% of people with hemophilia who received care at HTCs during this time participated. Data were collected from participants repeatedly over the years so they could be followed for the development of certain outcomes.
Surveillance reports were created to disseminate the information collected through the UDC program to care providers, public health workers, community advocates, health educators and planners, patients in the bleeding disorders community and others. The reports contain information about the demographics of the participants, their blood and factor product use, and the occurrence and treatment of joint and infectious diseases.
The most recent report to be released, the Report on the Universal Data Collection Program January 2014 focuses on UDC data collected during years 2005 through 2009. A total of 44,239 visits were made during the five-year interval, 8,816 of which were new enrollments and 35,423 of which were follow-up visits.
UDC data and reports are available to HTC staff, who can download electronic files and HTC-specific reports containing UDC data collected from participants at their HTC. In addition, cumulative national and regional reports are available to the public on CDC’s website.
