**5.2 Efficient**

To experience efficient care, patients would experience care that removes or reduces unnecessary waste and/or costs. Frequently, patients may experience repetitive tests that are done at different healthcare facilities. However, that repetitive test will lead to increased overall healthcare costs. At times, the repeat test may be necessary. However, unnecessary repetitive tests lead to unnecessary healthcare costs [44]. Thus, one may be interested in investigating how to reduce the use of unnecessary repetitive tests for appropriate specificity and sensitivity.
