No Stone Left Unturned: Utilization of an Organ Procurement Organization Donor Surgeon at Procurement Reduces...

The recent trend of organ procurement organizations (OPOs) employing independent surgeons for organ procurement has been developed with the goal of improving the supply of suitable organs for transplantation. We investigated the effects that the addition of an OPO-employed, organ-procurement specialist has on liver allograft discard rate, marginal organ utilization, and graft survival.

Organ Procurement and Transplant Network and OPO data were retrospectively studied between April 1, 2014' and July 31, 2019' within the Southwest Transplant Alliance donor service area. Liver procurements with an OPO-surgeon present (OPO-Present) were compared to those without the involvement of an OPO surgeon (OPO-Absent). Donor and recipient characteristics as well as outcomes were analyzed across groups using propensity score matching.

In total 869 OPO-Present liver allografts had similar rates of discard (5.2%) compared to 771 OPO-Absent livers (5.8%). However, after adjusting for donor risk, OPO-Present livers had a lower propensity of discard compared to OPO-Absent (3.4% versus 7.6%, P < 0.05). OPO-Present livers were more likely to be shared nationally (11.0% versus 4.8%, P < 0.001). Outcome analysis showed allograft survival of OPO-Present livers at 5 y was comparable to OPO-Absent livers (79.5% versus 80%, P = 0.34).

The presence of an OPO surgeon was associated with decreased liver allograft discard and increased utilization of marginal donor organs. The OPO surgeon's presence represents a potential strategy to increase organ utilization nationally.
