Use of genetic risks in pediatric organ transplantation listing decisions: A national survey.

ABSTRACT: There is a limited supply of organs for all those who need them for survival. Thus, careful decisions must be made about who is listed for transplant. Studies show that manifesting genetic disease can impact listing eligibility. What has not yet been studied is the impact genetic risks for future disease have on a patient's chance to be listed. Surveys were emailed to 163 pediatric liver, heart, and kidney transplant programs across the United States to elicit views and experiences of key clinicians regarding each program's use of genetic risks (ie, predispositions, positive predictive testing) in listing decisions. Response rate was 42%. Sixty-four percent of programs have required genetic testing for specific indications prior to listing decisions. Sixteen percent have required it without specific indications, suggesting that genetic testing may be used to screen candidates. Six percent have chosen not to list patients with secondary findings or family histories of genetic conditions. In hypothetical scenarios, programs consider cancer predispositions and adult-onset neurological conditions to be relative contraindications to listing (61%, 17%, and 8% depending on scenario), and some consider them absolute contraindications (5% and 3% depending on scenario). Only 3% of programs have formal policies for these scenarios, but all consult genetic specialists at least "sometimes" for results interpretation. Our study reveals that pediatric transplant programs are using future onset genetic risks in listing decisions. As genetic testing is increasingly adopted into pediatric medicine, further study is needed to prevent possible inappropriate use of genetic information from impacting listing eligibility.

Project description:Background & aimsLiver transplantation is the only treatment that increases survival times of patients with decompensated cirrhosis. Patients who live farther away from a transplant center are disadvantaged. Health care delivery via telehealth is an effective way to manage patients with decompensated cirrhosis remotely. We investigated the effects of telehealth on the liver transplant evaluation process.MethodsWe performed a retrospective study of 465 patients who underwent evaluation for liver transplantation at the Richmond Veterans Affairs Medical Center from 2005 through 2017. Of these, 232 patients were evaluated via telehealth, and 233 via in-person evaluation. Using regression models, we evaluated the differential effects of telehealth vs usual care on placement on the liver transplant waitlist. We also investigated the effects of telehealth on time from referral to initial evaluation by a transplant hepatologist, liver transplantation, and mortality.ResultsPatients in the telehealth group were evaluated significantly faster than patients evaluated in person, without or with adjustment for potential confounders (21.7 vs 79.5 d; P < .01). Telehealth also was associated with a significantly shorter time on the liver transplant waitlist (138.8 vs 249 d; P < .01). After propensity-matched analysis, telehealth was associated with a reduction in the time from referral to evaluation (hazard ratio, 0.15; 95% CI, 0.09-0.21; P < .01) and listing (hazard ratio, 0.26; 95% CI, 0.12-0.40; P < .01), but not to transplantation. In the intent-to-treat analysis of all referred patients, we found no significant difference in pretransplant mortality between patients evaluated via telehealth vs in-person. There was statistically significant interaction between model for end-stage liver disease (MELD)-Na scores and time to evaluation (P = .009) and placement on the transplant waitlist (P = .002), with telehealth offering greater benefits to patients with low MELD-Na scores.ConclusionsUse of telehealth is associated with a substantial reduction in time from referral to initial evaluation by a hepatologist and placement on the liver transplant waitlist, especially for patients with low MELD scores, with no changes in time to transplantation or pretransplant mortality. More studies are needed, particularly outside of the Veterans Administration Health System, to confirm that telehealth is a safe and effective way to expand access for patients undergoing evaluation for liver transplantation.

Project description:Background and objectivesCognitive impairment is common in patients with kidney disease and can affect physicians' perception and/or patients' ability to complete the pretransplant evaluation. We examined whether cognitive impairment influences the likelihood for transplant listing and whether patients with cognitive impairment take longer to be listed.Design, setting, participants, & measurementsWe conducted a single-center longitudinal cohort study. Patients presenting for their index kidney transplant evaluation were screened for cognitive impairment using the Montreal Cognitive Assessment. A score <26 indicated cognitive impairment. The transplant selection committee was blinded to the scores. Kaplan-Meier analysis assessed time to active listing by level of cognition. A Cox proportional hazards model that included age, sex, race/ethnicity, smoking, coronary artery disease, and diabetes was constructed to evaluate the association between Montreal Cognitive Assessment score and listing for transplant.ResultsIn total, 349 patients who underwent Montreal Cognitive Assessment testing at their initial visit were included in the analysis. Patients with cognitive impairment were more likely to be older, black, and smokers. The time to listing in patients with cognitive impairment was longer than the time to listing in those with no cognitive impairment (median time, 10.6 versus 6.3 months; log rank test P=0.01). Cognitive impairment was independently associated with a lower likelihood of being listed for transplant (hazard ratio, 0.93 per unit lower Montreal Cognitive Assessment score; 95% confidence interval, 0.88 to 0.99; P=0.02). A lower proportion of patients with cognitive impairment were listed compared with patients without cognitive impairment at 1 month (2% versus 11%), 6 months (17% versus 37%), and 1 year (23% versus 41%), (P<0.001 for all).ConclusionsCognitive impairment is associated with a lower likelihood of being listed for kidney transplant, and is associated with longer time to transplant listing.
