Overuse of preoperative laboratory coagulation testing and ABO blood typing: a French national study

Abstract

Background

Following publication of guidelines on routine preoperative tests, the French Society of Anaesthesiology and Intensive Care (SFAR), in association with French national public health insurance, conducted a survey to evaluate adherence to guidelines and the economic consequences.

Methods

Using the French Hospital Discharge Database and National Health Insurance Information system, tests performed during the 30 days before surgery were analysed for two situations: (1) standard laboratory coagulation tests and ABO blood typing in children able to walk and scheduled for tonsillectomy/adenoidectomy; and (2) ABO blood typing in adults before laparoscopic cholecystectomy, thyroidectomy, lumbar discectomy or breast surgery. Guidelines do not recommend any preoperative tests in these settings.

Results

Between 2013 and 2015, a coagulation test was performed in 49% of the 241 017 children who underwent tonsillectomy and 39% of the 133 790 children who underwent adenoidectomy. A similar pattern was observed for ABO blood typing although re-operation rates for bleeding on the first postoperative day were very low (0.12–0.31% for tonsillectomy and 0.01–0.02% for adenoidectomy). Between 2012 and 2015, ABO blood typing was performed in 32–45% of the 1 114 082 patients who underwent one of the four selected procedures. The transfusion rate was very low (0.02–0.31%). The mean cost for the four procedures over the 4 yr period was €5 310 000 (sd €325 000).

Conclusions

Standard laboratory coagulation tests and ABO blood typing are still routinely prescribed before surgery and anaesthesia despite current guidelines. This over-prescription represents a high and unnecessary cost, and should therefore be addressed.
