Final assessment of the ambulatory transfer potential for the coronary angiography patients in a teaching hospital in Malaysia

Introduction Our prior work over 2005 and 2006 validated the feasibility of our method to identify retrospectively transferable cases using IR DRG in-patient groups and exclusion criteria based mainly on severity of illness for same encounters. Now, we want to implement a method to identify behavioral changes required from the clinicians. In order to do so, we needed to demonstrate the full transferability and savings using our approach. To do so, we applied standard validity testing with a gold standard. We also tested additional global criteria of health status, taking into account all clinical conditions over the last three-year period, which would add to the retrospective predictions.
