Routine testing is not indicated in all admissions. Many tests are repeated unnecessarily.
As noted under the general recommendations from Choosing Wisely:
Don’t do regular tests but test in response to clinical questions.
Don’t do repeat tests if clinically stable; repeat only when clinically indicated.
Do not repeat laboratory tests for patients transferred into the ED who have laboratory results within reference ranges available from outside hospital.
Don’t do screening tests in low risk patients undergoing low risk surgery.
We also recommend:
Do not repeat the creatinine and electrolytes if they were normal unless there are clinical indications to suggest a likely change (eg hypotension, reduced urine output).
