The primary objective is to create a multicenter registry which captures information relating to the perioperative anesthesia course and management of children undergoing anterior cruciate ligament reconstruction and to examine practice patterns and incidence of complications. Data from any single institution involved in this registry will be used for local safety and quality improvement efforts. In addition data from each institution can be compared to the information from the entire group of institutions participating in the project, thus providing a measure for comparison with national practice. The aggregate multi-institutional data set will be used to develop quality benchmarks for national safety and quality improvement efforts and best practice recommendation. We believe that this registry can also demonstrate how web based data collection can be used to evaluate clinical anesthesia outcomes for surgeries with a low incidence of critical events but with significant variability in medical management.

This multi institutional registry will capture data relating to perioperative practices and complications, some of which may be relatively infrequent. The goal of this group is to create this registry to be used for local safety and quality improvement and multi-center benchmarking in this population. Reports generated from the registry will provide individual institutions with comparative data showing how their site performs compared to composite averages from all participating sites. Queries of the composite data set may allow for identification of factors associated with improved outcomes in this population. Future queries of the data-base for research purposes will require approval of the participating members of SPAIN.
