The significance and cost of preoperative laboratory screening in young healthy patients in a public hospital in Israel

We evaluated the clinical significance and cost of routine preoperative laboratory screening in young healthy patients in a public hospital. Three hundred consecutive young (aged 18-40 years), healthy (ASA I) patients undergoing minor elective surgical procedures were enrolled in this prospective study. A preoperative test was considered to be significant if its result lead to a new diagnose or to cancellation of surgery. The lab tests revealed only one new diagnosis. None of the procedures were cancelled. The total cost of the lab tests was NIS 114,000. Of this amount, NIS 104,000 could have been saved if the tests were ordered as required by the patients medical history and physical examination and not performed routinely. CONCLUSION: This study suggests that routine preoperative laboratory screening is not recommended prior to minor, elective surgery in young, healthy patients.
