Impact of deceased organ donor marijuana use on donor culture positivity and solid organ transplant recipient outcomes.

With the increasing prevalence of marijuana use in the US, many deceased organ donors have a history of marijuana use, raising concerns about infectious risks to transplant recipients. We performed a multicenter retrospective cohort study in which exposed donors were those with recent marijuana use (in the prior 12 months) and unexposed donors were those with no recent marijuana use. Primary outcomes included the following: (1) positive donor cultures for bacteria or fungi, (2) recipient infection due to bacteria or fungi within 3 months posttransplant, and (3) recipient graft failure or death within 12 months posttransplant. Multivariable regression was used to evaluate the relationship between donor marijuana use and each outcome. A total of 658 recipients who received organs from 394 donors were included. Recent marijuana use was not associated with donor culture positivity (aOR: 0.84, 95% CI: 0.39-1.81, P = .65), recipient infection (aHR: 1.02, 95% CI: 0.76-1.38, P = .90), or recipient graft failure or death (aHR: 1.65, 95% CI: 0.90-3.02, P = .11). Our data suggest that organs from donors with a history of recent marijuana use do not pose significant infectious risks in the early posttransplant period.

Intersectionality and Inclusive Serious Illness Communication in the Intensive Care Unit.

Serious illness communication can be especially distressing for patients who are critically ill and their loved ones who experience forms of discrimination based on identities such as their race, gender, sexual orientation, and other intersecting identities. In this article, we discuss the concept of intersectionality and its association with serious illness communication, decision-making, and care in the intensive care unit. Additionally, we present relevant concepts from clinical practice and contemporary nursing and health care literature to support critical care nurses in fostering more inclusive serious illness communication in the intensive care unit.
