Minority race and male sex as risk factors for non-beneficial gastrostomy tube placements after stroke

Background
Percutaneous endoscopic gastrostomy (PEG) tubes are widely used for enteral feeding after stroke; however, PEG tubes placed in patients in whom death is imminent are considered non-beneficial.
Aim
We sought to determine whether placement of non-beneficial PEG tubes differs by race and sex.
Design and setting/participants
In this retrospective cohort study, inpatient admissions for stroke patients who underwent palliative/withdrawal of care, were discharged to hospice, or died during the hospitalization, were identified from the Nationwide Inpatient Sample between 2007 and 2011. Logistic regression was used to evaluate the association between race and sex with PEG placement.
Results
Of 36,109 stroke admissions who underwent palliative/withdrawal of care, were discharge to hospice, or experienced in-hospital death, a PEG was placed in 2,258 (6.3%). Among PEG recipients 41.1% were of a race other than white, while only 22.0% of patients without PEG were of a minority race (p<0.001). The proportion of men was higher among those with compared to without a PEG tube (50.0% vs. 39.2%, p<0.001). Minority race was associated with PEG placement compared to whites (OR 1.75, 95% CI 1.57–1.96), and men had 1.27 times higher odds of PEG compared to women (95% CI 1.16–1.40). Racial differences were most pronounced among women: ethnic/racial minority women had over 2-fold higher odds of a PEG compared to their white counterparts (OR 2.09, 95% CI 1.81–2.41), while male ethnic/racial minority patients had 1.44 increased odds of a PEG when compared to white men (95% CI 1.24–1.67, p-value for interaction <0.001).
Conclusion
Minority race and male sex are risk factors for non-beneficial PEG tube placements after stroke.
