1. Review of DCD allocation scheme: the first 6 months Lisa Bradbury Statistics and Clinical Studies Renal Transplant Services Meeting 2015

2. Introduction Organs donated for transplantation are a national resource Kidneys should be allocated in an open, objective and transparent way DCD donor kidneys are the ‘norm’ rather than the ‘exception’ Deceased kidney donorsDeceased kidney-only transplants

3. DBD kidneysFormalised national allocation scheme for both kidneys DCD kidneys Non-standardised local arrangements Some centres were ‘pairing-up’ to share DCD kidneys For example: North Thames area, Edinburgh and Glasgow Local sharing arrangements may reflect difficulty in performing two same centre concurrent kidney transplants? Allocation prior to implementation of the scheme

4. One kidney retained locally, second kidney shared regionally within four pre-defined regions Both kidneys to be prioritised according to the 2006 DBD donor kidney allocation scheme principles To avoid significant changes to centre activity, donor age criteria will apply to manage the ‘phasing-in’ process New DCD kidney sharing scheme

7. New DCD kidney allocation process Offers made to named patients

8. Final DCD kidney allocation scheme

9. Kidney donor screening

10. Screening and offering was one informal process for SNODs o Utilisation of kidneys not maximised o Screening and offering is separated under new DCD Kidney Allocation Scheme New formalised screening process agreed o SNODs ‘screen’ o Screening centres: Cambridge, Cardiff, Guy’s, Leeds o Duty Office do all offering of DCD kidneys DCD kidney donor screening

11. Number of calls to local transplant centre (forms returned) Of 73 deemed acceptable; 19 unknown, 25 no consent, 29 consent Of 29 who’s family gave consent; 26 kidneys retrieved and 20 transplanted

12. Number of calls and proportion of acceptable donors OOR = Out of region Of 53 deemed acceptable; 20 unknown, 18 no consent, 15 consent Of 15 who’s family gave consent; 10 kidneys retrieved and 8 transplanted

22. Shewhart Charts The charts highlight variation in adult transplant activity in each centre Proportions and not actual numbers are plotted due to variability in donor numbers For each centre, each three-month period from 1 March 2013 to 28 February 2014 is represented The solid line represents the average number of DCD kidney only transplants in a 3-month period between 2012 and 2014 The dashed lines represent the control limits and are approximately 2 and 3 standard deviations above and below the average The upper limits indicate and increased level of transplant activity and the lower limits indicate a decreased level.

43. Median waiting time to transplant

44. Summary of activity Overall, DCD kidney donors and transplants have increased Belfast, Royal Free and WLRTC have seen increases in activity –Belfast have made more use of local donors –Royal Free and WLRTC are now performing more in line with the size of their waiting list Glasgow, Cardiff, Cambridge, Guy’s have seen decreases –Glasgow have increased activity in March 2015 –Cardiff have performed fewer transplants through the fast track scheme –Cambridge and Guy’s are now performing more in line with the size of their waiting list

45. Equity of access Donors aged 5 to 49 (5 to 64 in London)

46. Long waiting patients <1 year 1-3 years 3-5 years <5 years Before: 1 Sep 2013 – 31 Aug 2014 After:3 Sep 2014 – 28 Feb 2015

47. HLA matching of DCD transplants Level 1 (best match) Level 2 Level 3 Level 4 (worst match) Before: 1 Sep 2013 – 31 Aug 2014 After:3 Sep 2014 – 28 Feb 2015

48. Highly sensitised patients Before: 1 Sep 2013 – 31 Aug 2014 After:3 Sep 2014 – 28 Feb 2015

49. Cold ischaemia times

50. Cold ischaemia time of DCD transplants p=0.1 p=0.4p=0.5p=0.1p=0.9

51. Summary (1) Scheme went live on 3 rd September 2014 Designed to - Improve equity of access to a national resource - Optimise utilisation of DCD donor kidneys through formalised offering - Maintain (or reduce) overall cold ischaemia times General feedback on the scheme is positive - Potential impact on offering times needs to be addressed A six-month review of the screening centres to be undertaken shortly - Impact on screening centres - Donor suitability - More suitable way forward?

52. Summary (2) DCD Kidney activity has increased Better matching achieved through sharing Highly sensitised and long waiting patients have improved access to transplant Small reduction in cold ischaemia times Should we increase the upper age limit for sharing DCD kidneys through the scheme? –5 year increments –London experience, increase to 64 years?
