Study to Evaluate Current Trends in Appropriate Usage of Tread Mill Exercise Testing.

INTRODUCTION

Non-invasive tests are used to diagnose and prognosticate Coronary Artery Disease (CAD) patients and also in pre-operative evaluation and rehabilitation. Millions of these tests are performed worldwide in these situations. However, previous studies have shown inappropriate use of these tests.

AIM

The study was to evaluate the appropriate use of treadmill exercise test.

MATERIALS AND METHODS

The present retrospective study was done in Rajiv Gandhi Super Speciality Hospital, Raichur and Institute of Medical sciences and RKB Super Speciality Clinic, Raichur, Karnataka, India. Tread Mill Tests (TMT) which were done between November 2013 and February 2016 were included in the study. A total of 600 tests were evaluated for appropriateness. Demographic, clinical and risk factors, indications were studied.

RESULTS

Overall 298 (49.66%) tests were found to be inappro-priate. Younger age, female sex, pre-operative evaluation, evaluation in master health check up and insurance were predictors of inappropriate use (p<0.05) in this study.

CONCLUSION

The treadmill exercise testing appears to be particularly vulnerable to overuse in clinical setting due to its wide availability, affordability and awareness. The inappropriate use of the method, however, may result in additional unnecessary cost to health care system.
