                  <jats:title>Background</jats:title>

                  <jats:p>Infections, including common communicable infections such as influenza, frequently cause disease after organ transplantation, although the quantitative extent of infection and disease remains uncertain.</jats:p>

               </jats:sec>

               <jats:sec>

                  <jats:title>Methods</jats:title>

                  <jats:p>A cohort study was conducted to define the burden of notifiable infectious diseases among all solid organ recipients transplanted in New South Wales, Australia, 2000–2015. Data linkage was used to connect transplant registers to hospital admissions, notifiable diseases, and the death register. Standardized incidence ratios (SIRs) were calculated relative to general population notification rates, accounting for age, sex, and calendar year. Infection-related hospitalizations and deaths were identified.</jats:p>

               <jats:sec>

                  <jats:title>Results</jats:title>

                  <jats:p>Among 4858 solid organ recipients followed for 39 183 person-years (PY), there were 792 notifications. Influenza was the most common infection (532 cases; incidence, 1358 [95% CI, 1247–1478] per 100 000 PY), highest within 3 months posttransplant. Next most common was salmonellosis (46 cases; incidence, 117 [95% CI, 87–156] per 100 000 PY), then pertussis (38 cases; incidence, 97 [95% CI, 71–133] per 100 000 PY). Influenza and invasive pneumococcal disease (IPD) showed significant excess cases compared with the general population (influenza SIR, 8.5 [95% CI, 7.8–9.2]; IPD SIR, 9.8 [95% CI, 6.9–13.9]), with high hospitalization rates (47% influenza cases, 68% IPD cases) and some mortality (4 influenza and 1 IPD deaths). By 10 years posttransplant, cumulative incidence of any vaccine-preventable disease was 12%, generally similar by transplanted organ, except higher among lung recipients. Gastrointestinal diseases, tuberculosis, and legionellosis had excess cases among transplant recipients, although there were few sexually transmitted infections and vector-borne diseases.</jats:p>

                  <jats:p>There is potential to avoid preventable infections among transplant recipients with improved vaccination programs, health education, and pretransplant donor and recipient screening.</jats:p>

            <jats:title>Background.</jats:title>

            <jats:p>There is an imperative to maximize donation opportunities given ongoing organ shortages, but donor suitability assessments can be challenging.</jats:p>

          </jats:sec>

          <jats:sec>

            <jats:title>Methods.</jats:title>

            <jats:p>We analyzed an Australian cohort of potential deceased donors 2010 to 2013 to explore misclassification of cancer risk and potential strategies for improvement (decision support, real-time data linkage to existing data sets, and increasing risk tolerance). Cancer history perceived at referral was compared with verified cancer history in linked health records. Transmission risks were based on clinical guidelines. Potential donors declined due to cancer but verified low risk were missed opportunities; those accepted but verified high risk were excess-risk donors.</jats:p>

          </jats:sec>

          <jats:sec>

            <jats:title>Results.</jats:title>

            <jats:p>Among 472 potentially suitable donor referrals, 132 (28%) were declined because of perceived transmission risk and 340 (72%) donated. Assuming a low-risk threshold, there were 38/132 (29%) missed opportunities and 5/340 (1%) excess-risk donors. With decision support, there would have been 5 (13%) fewer missed opportunities and 2 (40%) more excess-risk donors; with real-time data linkage, 6 (16%) fewer missed opportunities and 2 (40%) fewer excess-risk donors; and with increased risk tolerance, 6 (16%) fewer missed opportunities and 11 (220%) more excess-risk donors.</jats:p>

          </jats:sec>

          <jats:sec>

            <jats:title>Conclusions.</jats:title>

            <jats:p>Potential donors’ cancer history is typically incomplete at referral. There are missed opportunities where decision support or more accurate cancer history could safely increase organ donors.</jats:p>

abstract = {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.

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.

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%CI:0.29–0.67), and those overseas-born than Australian-born (OR 0.54, 95%CI:0.41–0.72). For referrals both overseas-born and non-English speaking, families were both less likely to be asked for consent (OR 0.67; 95%CI:0.49–0.91) 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).

Intervention to improve consent rates from CALD families may increase donation.},

            <jats:title>Background</jats:title>

            <jats:p>Tension lies between the need to increase access to organ transplantation and the equally urgent need to prevent inadvertent transmission of infectious diseases or cancer from organ donors. Biovigilance, or the evaluation of potential donors, is often time-pressured and may be based on incomplete information.</jats:p>

            <jats:title>Objective</jats:title>

            <jats:p>The Safety and Biovigilance in Organ Donation (SAFEBOD) study aims to improve estimates of infection and cancer transmission risk and explore how real-time data access could support decision-making.</jats:p>

          </jats:sec>

          <jats:sec>

            <jats:title>Methods</jats:title>

            <jats:p>We will link existing donor referral, actual donor, recipient, and health-outcome data sets from 2000-2015 in New South Wales. Organ donor data sets will include the Organ Donor Characterizing Risk-Profile of Donors Study, the National Organ Matching System, the Australian and New Zealand Organ Donor Register, and the Australian and New Zealand Living Donor Kidney Register. Recipient data sets will include the Australian and New Zealand Dialysis and Transplant Register, the Australian and New Zealand Cardiothoracic Register, the Australian and New Zealand Islet and Pancreas Register, and the Australian and New Zealand Liver Transplant Register. New South Wales health outcome data sets will include HIV and AIDS Notifications and Surveillance Data, the Notifiable Conditions Information Management System, Admitted Patient Data Collection, Emergency Department Data Collection, the Central Cancer Registry, and the Cause of Death Data Collection. We will link organ donors to transplant recipients and health outcomes data sets using probabilistic data-matching based on personal identifiers. Transmission and nontransmission events will be determined by comparing previous cases in donors and posttransplant cases in recipients. We will compare the perceived-risk at referral with the verified risk from linked health outcome data sets and the odds of cancer or contracting an infectious disease in organ recipients from donors based on their transmission-risk profile and estimate recipient survival by donor transmission risk group.</jats:p>

          <jats:sec>

            <jats:title>Results</jats:title>

            <jats:p>Data were requested from each of the listed registries in September 2018, and data collection is ongoing. Linked data from all listed data sets are expected to be complete in September 2020.</jats:p>

          <jats:sec>

            <jats:title>Conclusions</jats:title>

            <jats:p>The SAFEBOD study will overcome current limitations in organ donation by accessing comprehensive information on referred organ donors and recipients in existing data sets. The study will provide robust estimates of disease transmission and nontransmission events based on recent data. It will also describe the agreement between perceived risk estimated at the time of referral and verified risk when all health outcome data are accessible. The improved understanding of transmission and nontransmission events will inform clinical decisions and highlight where current policies can be revised to broaden the acceptance of deceased donors.</jats:p>
