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

            <jats:p>The disparity between the demand for and supply of kidney transplants has resulted in prolonged waiting times for patients with kidney failure. A potential approach to address this shortage is to consider kidneys from donors with a history of common cancers, such as breast, prostate, and colorectal cancers.</jats:p>

          </jats:sec>

          <jats:sec>

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

            <jats:p>We used a patient-level Markov model to evaluate the outcomes of accepting kidneys from deceased donors with a perceived history of breast, prostate, or colorectal cancer characterized by minimal to intermediate transmission risk. Data from the Australian transplant registry were used in this analysis. The study compared the costs and quality-adjusted life years (QALYs) from the perspective of the Australian healthcare system between the proposed practice of accepting these donors and the conservative practice of declining them. The model simulated outcomes for 1500 individuals waitlisted for a deceased donor kidney transplant for a 25-y horizon.</jats:p>

          </jats:sec>

          <jats:sec>

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

            <jats:p>Under the proposed practice, when an additional 15 donors with minimal to intermediate cancer transmission risk were accepted, QALY gains ranged from 7.32 to 20.12. This translates to an approximate increase of 7 to 20 additional years of perfect health. The shift in practice also led to substantial cost savings, ranging between $1.06 and $2.3 million.</jats:p>

          </jats:sec>

          <jats:sec>

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

            <jats:p>The proposed practice of accepting kidneys from deceased donors with a history of common cancers with minimal to intermediate transmission risk offers a promising solution to bridge the gap between demand and supply. This approach likely results in QALY gains for recipients and significant cost savings for the health system.</jats:p>

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

            <jats:p>Kidneys from potential deceased donors with brain cancer are often foregone due to concerns of cancer transmission risk to recipients. There may be uncertainty around donors’ medical history and their absolute transmission risk or risk-averse decision-making among clinicians. However, brain cancer transmissions are rare, and prolonging waiting time for recipients is harmful.</jats:p>

          </jats:sec>

          <jats:sec>

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

            <jats:p>We assessed the cost-effectiveness of increasing utilization of potential deceased donors with brain cancer using a Markov model simulation of 1500 patients waitlisted for a kidney transplant, based on linked transplant registry data and with a payer perspective (Australian government). We estimated costs and quality-adjusted life-years (QALYs) for three interventions: decision support for clinicians in assessing donor risk, improved cancer classification accuracy with real-time data-linkage to hospital records and cancer registries, and increased risk tolerance to allow intermediate-risk donors (up to 6.4% potential transmission risk).</jats:p>

          </jats:sec>

          <jats:sec>

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

            <jats:p>Compared with current practice, decision support provided 0.3% more donors with an average transmission risk of 2%. Real-time data-linkage provided 0.6% more donors (1.1% average transmission risk) and increasing risk tolerance (accepting intermediate-risk 6.4%) provided 2.1% more donors (4.9% average transmission risk). Interventions were dominant (improved QALYs and saved costs) in 78%, 80%, and 87% of simulations, respectively. The largest benefit was from increasing risk tolerance (mean +18.6 QALYs and AU$2.2 million [US$1.6 million] cost-savings).</jats:p>

            <jats:p>Accepting kidneys from donors at increased risk of BBVs (2% from donors with increased-risk behaviors and 5% from donors with active or past HCV infection) incurred total costs of 311 303 Australian dollars with a gain of 8.53 QALYs.

A cost-saving of $19 214 and additional 0.09 QALYs (~33 d in full health) per person would be generated compared with declining these donors. Increasing the availability of kidneys with increased risk by 15% led to further cost-savings of $57 425 and additional 0.23 QALY gains (~84 d in full health).

<jats:p>The New Zealand Ministry of Health will use patients’ National Health Index (NHI) numbers to deterministically link individual records held in existing registry and administrative health databases in New Zealand to create the data platform. The initial data linkage will include a study population of incident patients captured in the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA), New Zealand Blood Service Database and the Australia and New Zealand Living Kidney Donor Registry (ANZLKD) from 2006 to 2019 and their linked health data. Health data sources will include National Non-Admitted Patient Collection Data, National Minimum Dataset, Cancer Registry, Programme for the Integration of Mental Health Data (PRIMHD), Pharmaceutical Claims Database and Mortality Collection Database. Initial exemplar studies include 1) kidney waitlist dynamics and pathway to transplantation; 2) impact of mental illness on accessing kidney waitlist and transplantation; 3) health service use of living donors following donation.</jats:p>

<jats:title>Conclusion</jats:title>

<jats:p>The AcceSS and Equity in Transplantation (ASSET) linked data platform will provide opportunity for population-based health services research to examine equity in health care delivery and health outcomes in New Zealand. It also offers potential to inform future service planning by identifying where improvements can be made in the current health system to promote equity in access to health services for those in New Zealand.</jats:p>

                  <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: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: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: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>

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:p>We conducted a cohort study of all potential organ donors referred in NSW, Australia, 2010–2018.

          </jats:sec>

          <jats:sec>

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

            <jats:p>There were 624 of 5749 potential donors (10.9%) perceived to have increased BBV transmission risk. This included 298 of 5749 (5.2%) with HCV (including HBV coinfections) and 239 of 5749 (4.2%) with increased risk behaviors (no known BBV). Potential donors with HCV and those with increased risk behaviors were younger and had fewer comorbidities than baseline risk potential donors (<jats:italic toggle="yes">P</jats:italic> < 0.001). Many potential donors (82 with HCV, 38 with risk behaviors) were declined for donation purely because of perceived BBV transmission risk. Most were excluded before BBV testing. When potential donors with HCV did donate, they donated fewer organs than baseline risk donors (median 1 versus 3, <jats:italic toggle="yes">P</jats:italic> < 0.01), especially kidneys (odds ratio 0.08, <jats:italic toggle="yes">P</jats:italic> < 0.001) and lungs (odds ratio 0.11, <jats:italic toggle="yes">P</jats:italic> = 0.006).</jats:p>

          <jats:sec>

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

            <jats:p>Of 5089 deaths in 16 329 kidney transplant recipients (158 325 person-years), 918 (18%) were cardiac. An increased risk of circulatory death was associated with older age (<jats:italic toggle="yes">P</jats:italic> < 0.001), male sex (<jats:italic toggle="yes">P</jats:italic> < 0.001), longer dialysis duration (<jats:italic toggle="yes">P</jats:italic> = 0.004), earlier era of transplantation (<jats:italic toggle="yes">P</jats:italic> < 0.001), ever graft failure (<jats:italic toggle="yes">P</jats:italic> < 0.001), known coronary artery disease (<jats:italic toggle="yes">P</jats:italic> = 0.002), and kidney failure from diabetes or hypertension (<jats:italic toggle="yes">P</jats:italic> < 0.001). The cardiac SMR was 5.4 [95% confidence interval (CI): 5.0-5.8], falling from 8.0 (95% CI: 4.9-13.1) in 1988 to 5.3 (95% CI: 4.0-7.0) in 2013 (<jats:italic toggle="yes">P</jats:italic> < 0.001). Females, particularly young ones, had significantly higher relative cardiac mortality than men. In recipients aged 40 years, the cardiac SMR was 26.5 (95% CI: 15.0-46.6) in females and 7.5 (95% CI: 5.0-11.1) for males.</jats:p>

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).

We included kidney transplant recipients from the Australian and New Zealand Dialysis and Transplantation Registry, 1980–2013. Date of death and underlying cause of death were ascertained by data‐linkage and classified using ICD10AM codes. Indirect standardisation was used to estimate standardised mortality ratios (SMR). There were 5,284 deaths in 17,628 kidney transplant recipients over 175,084 person‐years of observation, including 1,061 (20%) cancer deaths. Relative cancer mortality was higher than the general population for all‐site (SMR 2.9, 95% CI 2.7–3.1) cancer and highest for nonmelanoma skin cancer (SMR 50.9, 95% CI 43.5–59.6) and lymphoma (SMR 42.2, 95% CI 35.3–50.5). Relative cancer mortality decreased with increasing age in men (<jats:italic>p</jats:italic> < 0.001) and women (<jats:italic>p</jats:italic> = 0.001) but never reached parity with the general population.

Our study shows cancer mortality in kidney transplant recipients was higher than expected in the general population. The magnitude of excess mortality varied by cancer site, age and sex. Further evidence is needed to identify whether this variation is due to differences at diagnosis or access and effectiveness of cancer treatments in this population.</jats:p>},

            <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>

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>

Among 17 628 kidney transplant recipients, there were 158 stroke deaths and 5126 nonstroke deaths in 175 084 person-years. Those aged 30–49 years experienced more stroke deaths than expected, especially women (SMR in females: 19.7 [95% confidence interval, 12.9-30.3] and males: 9.1 [95% confidence interval, 5.6-14.6]). Higher risk of stroke death was associated with older age at transplant, ever graft failure, earlier era of transplant, preexisting cerebrovascular disease, and no previous malignancy. Polycystic kidney disease did not result in different SMR.

Kidney transplant recipients had excess stroke deaths, particularly at younger ages and women. Preexisting cerebrovascular disease was a potentially modifiable risk factor for stroke death, suggesting further studies of secondary stroke prevention for kidney transplant recipients.},

abstract = {Research suggests patients treated over weekends experience poorer outcomes. Only one US‐based study explored this weekend effect in organ donation, specifically the kidney discard rate. In Australia potential donors are referred to a donation service, and donation proceeds if family consent is granted and the donor is deemed medically suitable to donate. Organ procurement occurs when utilization is almost certain hence discard rates are much lower than in the USA.

abstract = {Increasing organ donation rates in Australia have been exceeded by a rise in potential donor referrals not proceeding to donate. Referral evaluation is resource-intensive. We sought to characterize organ donor referrals in New South Wales, Australia, and identify predictors of referrals not proceeding to donation.

We performed a cohort study of NSW Organ and Tissue Donation Service logs 2010–2015, describing the prevalence and impact of comorbidities on referral outcome. Logistic regression was used to identify comorbidities influencing outcome and predict probability of donation.

Of 2977 referrals, 669 (22%) donated and 2308 (78%) did not. Despite increasing donation rates, the proportion proceeding to donate declined 2010–2015. Among referrals, the prevalence of all comorbidities except cerebrovascular disease increased and was higher among nondonors. History of cardiac disease, ≥65 years of age, chronic kidney or liver disease, malignancy, and absence of cerebrovascular disease were all significantly (P< 0.01) associated with non donation. Hypertension and diabetes did not significantly impact outcome. Predicted probability of donation varied from <1% to 54% depending on comorbidity burden of the referral.

Comorbidity burden among donor referrals is increasing. The presence of particular comorbidities may significantly impact referral outcome. A better understanding of referral characteristics associated with non donation may improve the efficiency of the referral process in the context of encouraging routine referrals.},
