Causes of lowered family consent rate for organ donation

ObjectiveTo fill the evidence gap on the value of a single brain death (SBD) or dual brain death (DBD) examination by providing data on irreversibility of brain function, organ donation consent, and transplantation.MethodsTwelve-year tertiary hospital and organ procurement organization data on brain death (BD) were combined and outcomes, including consent rate for organ donation and organs recovered and transplanted after SBD and DBD, were compared after multiple adjustments for covariates.ResultsA total of 266 patients were declared BD, 122 after SBD and 144 after DBD. Time from event to BD declaration was longer by an average of 20.9 hours after DBD (p = 0.003). Seventy-five (73%) families of patients with SBD and 86 (72%) with DBD consented for organ donation (p = 0.79). The number of BD examinations was not a predictor for consent. No patient regained brain function during the periods following BD. Patients with SBD were more likely to have at least 1 lung transplanted (p = 0.031). The number of organs transplanted was associated with the number of examinations (β coefficient [95% confidence interval] −0.5 [−0.97 to −0.02]; p = 0.044), along with age (for 5-year increase, −0.36 [−0.43 to −0.29]; p < 0.001) and PaO2 level (for 10 mm Hg increase, 0.026 [0.008–0.044]; p = 0.005) and decreased as the elapsed time to BD declaration increased (p = 0.019).ConclusionsA single neurologic examination to determine BD is sufficient in patients with nonanoxic catastrophic brain injuries. A second examination is without additional yield in this group and its delay reduces the number of organs transplanted.

Deceased Organ Donation

Abstract Background: An emerging strategy to increase deceased organ donation is to use dedicated donation physicians to champion organ donation. We sought to conduct a systematic review of the effectiveness of donation physicians in improving organ donation outcomes.Methods: A systematic review was conducted following Cochrane principles. MEDLINE, Embase, and CINHAL databases were searched from inception to March 26, 2020. Quantitative studies examining the effects of donation physicians on all deceased organ donation outcomes were considered for inclusion. Review articles, editorials and opinion articles, and case studies were excluded. Study selection was completed independently by two team members; all discrepancies were resolved by consensus. Two team members independently extracted data from studies. Results: A total of 1,017 studies were screened, and 12 met inclusion criteria. Included studies were published between 1994 and 2019. Half used an interrupted time series design (n = 6; 50%), three (25%) were cohort studies, and three (25%) used a before-and-after study design. Outcomes (reported in greater than 50% of included articles) included consent/refusal rate (n = 8; 67%), number of potential donors (n = 7; 58%), and number of actual donors (n = 7; 58%). Across studies and design types, there was an increase in potential organ donors ranging from 8 to 143% (Mdn = 33%), an increase in actual organ donors from 15 to 113% (Mdn = 27%), an increase in donor consent rate from -3 to 258% (Mdn = 12%) and an increase in deceased donor transplants from 13 to 24% (Mdn = 19%) following the introduction of donation physicians.Conclusions: Donation physicians have the potential to significantly improve deceased organ donation. Further implementation and evaluation of donation physician programs is warranted. However, implementation should be undertaken with a clear plan for a methodologically rigorous evaluation of outcomes.

ObjectivesTo determine the short-term impact of a soft opt-out organ donation system on consent rates and donor numbers.DesignBefore and after observational study using bespoke routinely collected data.SettingNational Health Service Blood and Transplant.Participants205 potential organ donor cases in Wales.InterventionsThe Act and implementation strategy.Primary and secondary outcomesConsent rates at 18 months post implementation compared with 3 previous years, and organ donor numbers 21 months before and after implementation. Changes in organ donor register activity post implementation for 18 months.ResultsThe consent rate for all modes of consent was 61.0% (125/205), showing a recovery from the dip to 45.8% in 2014/2015. 22.4% (46/205) were deemed consented donors: consent rate 60.8% (28/46). Compared with the 3 years before the switch there was a significant difference in Welsh consent rates (χ2 p value=0.009). Over the same time period, rest of the UK consent rates also significantly increased from 58.6% (5256/8969) to 63.1% (2913/4614) (χ2 p value<0.0001), therefore the Wales increase cannot be attributed to the Welsh legislation change. Deceased donors did not increase: 101 compared with 104. Organ donation registration increased from 34% to 38% with 6% registering to opt-out.ConclusionThis is the first rigorous initial evaluation with bespoke data collected on all cases. The longer-term impact on consent rates and donor numbers is unclear. Concerns about a potential backlash and mass opting out were not realised. The move to a soft opt-out system has not resulted in a step change in organ donation behaviour, but can be seen as the first step of a longer journey. Policymakers should not assume that soft opt-out systems by themselves simply need more time to have a meaningful effect. Ongoing interventions to further enhance implementation and the public’s understanding of organ donation are needed to reach the 2020 target of 80% consent rates. Further longitudinal monitoring is required.
