Is type and screen only policy safe for patients undergoing elective lobectomy?

Abstract

Objective: The purpose of this study was to establish the safety and feasibility of a recently adopted policy to type and screen (TS) (group and save) only for selected patients who had low likelihood of transfusion requirement.

Methods: The TS only policy was applied to patients undergoing first-time elective lobectomy with Hb of >11 g/dl, aged <70 years, with no clotting abnormality and no history of neoadjuvant therapy. A retrospective analysis of prospectively collected data was made of 208 consecutive patients undergoing elective lobectomy from November 2009 to October 2010. The patients who were only type and screened (Group TS, n = 87) were compared with those who had preoperative cross matching (XM) (Group XM, n = 121). The perioperative characteristics, transfusion requirements and outcomes were compared between the two groups.

Results: Preoperative characteristics of the two groups were similar, except that the XM group were significantly older, with lower mean preoperative haemoglobin levels. Postoperative complications (9 vs 13%, P = 0.24) and hospital mortality (0 vs 0.8%, P = 0.5) were similar between TS and XM, respectively. On the day of operation, 16 patients (13%) required transfusion in the XM group. Six patients in the TS group were cross matched, of whom only 3 (3.4%) actually required transfusion. The mean postoperative Hb levels in XM were also significantly lower (12.96 vs 10.88 gm/dl). In the XM group, 260 units of blood were unnecessarily cross matched and had to be returned to the blood bank compared with zero units in the TS group. There was no delay caused by unavailability of blood at the time of clinical need.

Conclusion: Our data suggest that it is safe and feasible to adopt a policy of type and screen only in selected patients undergoing elective lobectomy, who have low likelihood of transfusion requirement.
