To avoid mistakes that affect safety, quality, and cost, know what equipment and supplies are needed and how the test is performed. Communication errors account for more incorrect results than do technical errors. Properly identify and label every specimen as soon as it is obtained. Bar code technology reduces transcription error rates, and data entry is faster and more accurate. Determine the type of sample needed and the collection method to be used.
In addition, the following should also be considered:
Is the test invasive or noninvasive?
Are contrast media injected or swallowed?
Is there a need to fast?
Are fluids restricted or forced?
Are medications administered or withheld?
What is the approximate length of the procedure?
Are consent forms properly completed?
Is a local anesthetic agent, conscious sedation, oxygen, analgesia, or anesthesia required?
Report test results as soon as possible. Critical values must be reported immediately (STAT, Latin: statim, instantly/immediately) to the appropriate healthcare provider (e.g., primary provider, nurse practitioner, nurse, or physician assistant [PA]), depending on institutional policy.
Instruct patients and their significant others regarding their responsibilities. Accurately outline the steps of the testing process and any restrictions that may apply. Conscientious, clear, timely communication among healthcare departments can reduce errors and inconvenience to both staff and patients.
