title: Design and development of an Internet registry for congenital heart defects.
abstract: BACKGROUND
  Congenital Heart Defects (CHD) are conditions that encompass more than 50 diagnoses and are due to developmental abnormalities early in fetal life. The King Faisal Specialist Hospital and Research Centre in the Kingdom of Saudi Arabia treats approximately 100 new cases per month. We recently developed a new CHD Registry that captures, stores and processes our data via the Internet.
  
  
  METHODS
  The Registry was developed using Hypertext Markup Language (HTML), Microsoft Active Server Pages and Microsoft Structured Query Language (SQL).
  
  
  RESULTS
  Details of CHD cases are captured in a World Wide Web (WWW) Registry, permitting any browser-enabled PC or Mac to participate fully in all registry functions, including data-entry, viewing, editing, searching, reporting, validating, charting, and exporting data subsets to statistics packages. It includes "administrative" features and an active security system. The paper forms have been designed to reflect the "look and feel" of the Web pages. Automatic validation procedures are also included.
  
  
  CONCLUSIONS
  Our Registry has been in operation for 3 years. It serves 10 PCs and contains more than 3,000 registered cases of CHD. It is the first CHD Registry to be fully functional on the Internet. It is also the first dedicated CHD registry, and the first to routinely report on the full spectrum of CHD diagnoses. The WWW offers several logistical advantages to disease registries, especially those that represent large regions. It also offers the possibility of sharing resources between registries, facilitating the aggregation and analysis of disease data on a world-wide scale. This is useful for rare diseases such as CHD (see http://rc.kfshrc.edu.sa/chdr/demo/).
