Original ArticleThe Foundation and Launch of the Melbourne Interventional Group: A Collaborative Interventional Cardiology Project
Introduction
The ability to record clinical data pertaining to interventional coronary angioplasty procedures is the foundation for evaluating future outcomes. In Australia, the majority of institutions collect information for local use only, with varied data elements collected and variable definitions used. At present, no uniform data collection or clinical follow-up exists, indicating a need for a large-scale collaborative group. Multicentre data collection has proven to be a useful tool in examining short and long-term success, with an ability to identify variables associated with higher risks. These variables can ultimately be used to develop predictive risk-adjusted multivariate models.1, 2, 3, 4 Cardiology registries also address the gap between the highly selected type of patient enrolled in randomised clinical trials and real-world practice.5 Retrospective analyses also bring in to play problems of missed data and recall bias; hence, prospective data collection via a central standardised registry is essential.
The Melbourne Interventional Group is a collaborative venture to record current interventional coronary procedures and perform longer term follow-up. This model is similar to the established Cardiac Surgical database (Australasian Society of Cardiac and Thoracic Surgeons).6, 7 The potential advantages of collaboration involve large-scale analysis of current interventional strategies (e.g. drug-eluting stents, evaluation of new technologies and cost-effective analysis), provide a basis for multi-centred clinical trials and allow comparison of clinical outcomes with our surgical colleagues.

Aims of Melbourne Interventional Group
The goals of MIG are twofold: (1) To establish a collaborative coronary angioplasty registry with 30-day and 12-month clinical follow-up and (2) facilitation of multi-centred randomised clinical trials targeted at interventional cardiology. The development and implementation of the registry appears critical as it provides a basis for performing clinical trials. The eventual goal of MIG is to provide a contemporary appraisal of Australian interventional cardiology practice, with opportunities to
Establishing a Dataset
MIG case report forms are designed to document detailed demographic, clinical and procedural characteristics and current interventional practice patterns for patients undergoing PCI in Victoria (Supplementary data, Appendix B). Additionally, we aim to document medical therapy in the peri-procedural period. These factors are analysed with reference to in-hospital and 12-month clinical outcomes.
The four-page standardised data abstraction form was developed by a database working group within MIG.
Conclusions
The MIG collaborative group comprising a broad range of Victorian hospitals will provide an insight into contemporary Australian interventional Cardiology practice. The established registry documents demographic, clinical and procedural characteristics of consecutive patients undergoing PCI and permits analysis of those characteristics at 30 days and 12 months. The collaborative venture will facilitate multi-centred randomised clinical trials targeted at interventional cardiology. Ultimately,
