Effect of language and country of birth on the consent process and medical suitability of potential organ donors; a linked-data cohort study 2010-2015.

ABSTRACT

PURPOSE: Australia has unmet need for transplantation. We sought to assess the impact of cultural and linguistic diversity (CALD) on family consent and medical suitability for organ donation. METHOD: Cohort study of New South Wales donor referrals, 2010-2015. Logistic regression estimated effects of primary language other than English and birthplace outside Australia (odds ratios OR, with 95% confidence intervals, 95%CI). Outcomes were whether families were asked for consent to donation, provided consent for donation, and whether the referral was medically suitable for donation. RESULTS: Of 2977 organ donor referrals, a similar proportion of families had consent for donation was sought between non-English speakers and English speakers (p = .07), and between overseas-born compared to Australian-born referrals (p = .3). However, consent was less likely to be given for both non-English speakers than English speakers (OR 0.44, 95%CI0.29-0.67), and those overseas-born than Australian-born (OR 0.54, 95%CI0.41-0.72). For referrals both overseas-born and non-English speaking, families were both less likely to be asked for consent (OR 0.67; 95%CI0.49-0.91) or give consent (OR 0.24; 95%CI0.16-0.37). There was no difference in medical suitability between English speakers and non-English speakers (p = .6), or between Australian-born and overseas-born referrals (p = .6). CONCLUSION: Intervention to improve consent rates from CALD families may increase donation.
