“…Indeed, we now believe that in order to perform meaningful multi-institutional analyses, any database must incorporate the following seven essential elements 1 –4 : - use of a common language and nomenclature,
- use of a database with established uniform core data elements for collection of information,
- incorporation of a mechanism to evaluate case complexity,
- availability of a mechanism to assure and verify the completeness and accuracy of the data collected,
- collaboration between medical and surgical subspecialties,
- standardization of protocols for lifelong longitudinal follow-up.
- Incorporation of strategies for quality assessment and quality improvement.
The four preceding articles in this issue of The World Journal for Pediatric and Congenital Heart Surgery ( WJPCHS ) all focus on aspects of methodology related to outcomes assessment and quality improvement for congenital and pediatric cardiac disease. 5 –8 A fifth article published later in this issue of WJPCHS also relates quite closely to this topic 9 and is published as part of the proceedings of PCICS 2010 (the Eighth International Conference of the Pediatric Cardiac Intensive Care Society, Miami Beach, Florida, USA; December 8-11, 2010). Each of these five articles adds new knowledge to previous work in this area and expands the rapidly evolving science of “the assessment of outcomes and the improvement of quality of the treatment of patients with congenital and pediatric cardiac disease.”…”
