3 Introduction & Acknowledgments 21/11 proved to be another busy year for the Renal Transplant Unit. The compilers of this report acknowledge the contributions from each and every member of the transplant team: Medical, Ward, Outpatient, Donor Transplant Coordinators, Specialist Nurses, Secretarial, Clerical and Transplantation Laboratory staff of all grades, and others from associated dialysis centres who have contributed to make this another successful year. Special thanks must also go to living donors and the families of deceased donors, without whom no transplants would have been possible. 3

11 Pre-emptive Transplantation The Renal Association recommends that pre-emptive transplantation should be the treatment of choice for all suitable patients whenever a living donor is available. The table below details pretransplant renal replacement therapy for all adult kidney alone recipients transplanted during 21/11 by referral network sector.

The median CIT time is shown for each financial year, as well as since the introduction of virtual crossmatching in December 28. The scatter plot shows a strong trend toward shorter CIT times with virtual crossmatching, with lower median CIT times since this method was introduced. Median CIT continues to decrease. CIT time and Virtual Crossmatching Virtual crossmatching was introduced for on 1/12/28. The purpose of this approach is to reduce the cold ischaemia time without compromising the safety of transplantation. A virtual crossmatch can be performed pre-transplant whereby the donor HLA type is reviewed against the patient s HLA antibody profile to determine whether the patient has donor-directed antibodies that would cause a positive crossmatch test result. Patients who have been rigorously assessed and defined as unsensitised can safely proceed to transplant before the crossmatch test result is available. This is intended to reduce the time spent awaiting a crossmatch result and in turn cold ischaemia time. 2/5/211 From April 211, cold ischaemia time will be a QIPP measure, with a target of 9% of deceased donor cold ischaemia times in a given month to be below 18 hours. This will decrease to 16 hours from September

15 CMFT Kidney and Pancreas Transplant Waiting List Demographics and Summary Table Data is based on all patients on the CMFT kidney and pancreas transplant waiting list at the end of each financial year. 28/9 29/1 21/11 Patients on list at end of year 878 [+1.2%] 919 [+4.7%] 915 [-.4%] Male 54 (57.4%) 5 (54.4%) 59 (55.6%) Age Range (in years) Time on transplant list range in months, active patients Median time on transplant list in months, active patients Patients active 572 (65.1%) 63 (65.6%) 67 (66.3%) Patients suspended 36 (34.9%) 316 (34.4%) 39 (33.7%) Patients waiting for kidney alone transplant 783 [+9.4%] 815 [+4.1%] 82 [+.6%] Patients waiting for simultaneous pancreas and kidney transplant 79 [+19.7%] 89 [+12.7%] 85 [-4.5%] Patients waiting for simultaneous heart and kidney transplant 1 1 Patients waiting for pancreas alone transplant 16 [+6.7%] 14 [-12.5%] 9 [-35.7%] () indicates % of total [ ] indicates % change from previous year Paediatric patients on CMFT Kidney and Pancreas Transplant Waiting list.

16 Pancreatic Islet Cell Waiting List The pancreatic islet transplantation programme began in 28, but it was not until February 21 that the unit s first transplant was performed. The table below details some key information about the programme. There has been a reduction in referral activity since the initial influx of patients at the start of the programme, and this is also reflected by the reduction in number of patients on the waiting list. 28/9 29/1 21/11 Number of patients on the waiting list Number of patients active on the waiting list Number of islet transplants 1 1 CMFT Kidney and Pancreas Transplant List by Organ Required CMFT Kidney and Pancreas Transplant List by Organ Required Kidney and Pancreas 9.5%(85) Pancreas alone.3% (3) Kidney 89.4% (799) Other 1.% Kidney and Heart.1% (1) Pancreas after kidney.7% (6) Fig 14: Organs required by adult patients listed on the CMFT kidney and pancreas transplant list. 16

17 CMFT Kidney & Pancreas Transplant list, April 21 by age CMFT Kidney and Pancreas Transplant list by age range, April 211 Number of patients Kidney alone Pancreas Age range Fig 15: This graph illustrates the age distribution among potential recipients listed for kidney and pancreas transplantation. The median age for adult kidney patients was 54.4 years and for pancreas patients 41.8 years. Time to enter CMFT Kidney and Pancreas Transplant Waiting list The time taken to complete the transplant listing process is audited on an annual basis. This time period is measured by calculating the number of days elapsed between the date of the referring Nephrologist s signature on each patient s Request to List Form, the date this form is received by the Transplantation Laboratory and the date they enter the transplant list. The graph below illustrates median listing times for patients from each referral centre over the last 3 years, including the time taken for the Transplantation Laboratory to process listings.

The number of patients on the waiting list has almost doubled over the last 1 years whereas the number of transplants carried out has not increased to mirror this. It can also be seen that the proportion of suspended patients on the transplant list has increased over the years by the widening gap between the total number of patients and active patients on the list.

19 Five Year Cohort Study on Waiting Time In 21, waiting time to transplant was audited by studying a cohort of patients listed in the same calendar year. The 22 adult patients who were listed for kidney alone transplantation at CMFT in 25 were followed up 5 years later in September 21 and their outcomes assessed. The aim of this audit was to identify factors likely to affect waiting time, and also to provide both clinicians and patients with realistic expectations of waiting time.

21 Waiting Time to Transplant by Age In this instance the Kaplan-Meier curve is used to illustrate time to transplant rather than survival. All patients listed for first deceased donor kidney alone transplant during 25 and 26 were followed over a 5 year period and censored for death, permanent removal from the transplant list and living donor transplant, and the results presented by age group. The percentage of each group still waiting after 5 years is given for each age range. % of group still awaiting transplant Time to first deceased donor kidney transplant; patients listed by age group Access to transplant 25/6 21/11 Patient age group (% still waiting at 5 years) Age 75+ years (1%) Age years (72.2%) Age years (47.9%) Age years (46.3%) Age years (18.6%) Age <18 years (%) Time since transplant listing in years Fig 23: Time to first deceased donor kidney transplant, showing considerable variation by recipient age. Whilst all paediatric recipients had received a transplant after around 3 years, the majority of recipients aged over 65 were still waiting after 5 years. 21

The new allocation scheme was intended to bring about fairer access to transplantation and reduce wide variability in waiting times by allocating organs on a national basis, prioritising rarer HLA types and patients who had waited a long time. Prior to the introduction of the new allocation scheme, between April 25 and March 26, it is clearly seen at the bottom of the plot that there appears to be a dense concentration of transplants taking place within a short time of entering the transplant list, with some isolated long waits. At that point median time to transplant was 1.14 years. During the year following introduction of the new allocation scheme, the median time to transplant increased to 4.95 years. On the plot the distribution of transplants is seen to be far more homogenous after April 6. Over the next 2 years the median time to transplant is seen to fall, which may be due to long waiting patients from before implementation of the new allocation scheme having received transplants. During 29/1 and 21/11 the median time to transplant is seen to rise slightly again, but this may be due in part to several patients who had been on the waiting list for many years before finally receiving transplants during this period. 22

23 Source of Transplant Referrals Patients are referred to the CMFT Renal Transplant Unit from 3 network sectors, each encompassing a group of hospitals in the North West region. The Unit also receives Extra Contractual Referrals (ECRs) from outside these referral sectors. Paediatric patients aged 18 or under are referred from Alder Hey or Central Manchester Children s Hospitals, with occasional exceptions in special cases. Full lists of hospitals covered by each network sector are given in the appendix. The tables below detail the referral network origin of patients receiving kidney alone deceased donor transplants during 21/11 and also those on the transplant list as of April 211 for purposes of comparison. The bottom rows of the table express the number of patients from each area transplanted during 21/11 as a percentage of the number listed from each area, and again as a percentage of the number active on the transplant list from each area.

On the CMFT Kidney and Pancreas Transplant list as of 1 st April 211 this proportion was 33.5% for adults awaiting kidney alone transplantation, with 13% of all patients on the list having been suspended for over 12 months. In 29/1 these figures were 34.3% and 16.1% respectively. The proportion of suspended patients, although the differences are not great, did vary by referral network sector. GM East had the highest percentage of long term suspensions (17.5%) but the lowest percentage of short term suspensions (11.9%) and overall total suspensions (29.4%). GM West had the highest overall percentage of suspended patients with 39.4%. 23

There is considerable variation between the areas, with the highest proportion of people both listed and and transplanted in the GM West sector, and the lowest in Cumbria and Lancashire. These differences may be due to a number of factors; demographic differences, epidemiological factors and referral patterns for transplantation. Figures in brackets denote the previous year s figures.

26 Access to transplant for patients on dialysis across referral network sectors These figures are a guide to the number of patients on the kidney transplant list and the number receiving deceased donor kidney alone transplants relative to the number of patients receiving dialysis (including both hospital and home haemodialysis and peritoneal dialysis) from each referral network sector, as of March 211. The numbers shown cannot translate directly to the numbers of patients on dialysis either being listed for transplant or receiving transplants as they do not account for pre-emptive transplants (transplants taking place before dialysis is commenced) or listing prior to dialysis being commenced. The variations seen, as before, may be due to epidemiological and demographic factors, and referral patterns for transplantation.

27 Graft Survival The two graphs and table below illustrate graft survival for first deceased donor kidney alone transplants at CMFT, with patient survival given overleaf. Percentage survival for both CMFT and the UK by transplant type is given in the table at the bottom of the page. Graft survival is censored for death with functioning graft. 1 year graft survival, 1st adult kidney transplant recipients by transplant type Cumulative Survival Living donor kidney (n=17) DBD kidney (n=234) DCD kidney (n=6) P =.7(NS) Time in years Fig 29: 1 year graft survival by transplant type.
