Citation preview
Kidney Transplantation CommitteeSpring 2014
1. Waiting time calculation - pre-registration dialysis time added
2. Candidate classification - Estimated Post Transplant Survival (EPTS) score
3. Kidney donor classification - replace SCD/ECD with Kidney Donor Profile Index (KDPI)
4. Priority for sensitized candidates - calculated panel reactive antibody (CPRA) sliding scale
Allocation component changes
5. Blood type eligibility - A2 and A2B to B compatible
6. Pediatric kidney allocation – KDPI priority
7. Kidney payback policy – eliminated
8. Kidney variances – eliminated
Allocation component changes
Communicate with referring physicians:
oPre-emptive listing is still advantageous
oCandidates can accrue time with GFR<=20ml/ml
oPriority for 0-ABDR mismatch offers
Importance of early referral

Adult Accrue time when listed once on dialysis or when GFR or CRCL is =/< 20 ml/min

Change #2: Candidate classification
Current NewNo priority based on estimated post-transplant survival
The 20% of adult candidates who have the longest EPTS receive priority for kidneys from donors with KDPI scores in the top 20%.

Longevity matching
Action: Review waiting time
Action: Input and confirm data
Prior living donors get 4 points
Action: Assess for living donors
Current NewClassified as SCD or ECD based on:
o donor ageo history of hypertensiono creatinine o cerebrovascular accident as
cause of death
Classified by KDPI based on:odonor ageoheight oweight oethnicityohistory of hypertension ohistory of diabetes ocause of death oserum creatinineohepatitis C virus statusodonation after circulatory death
Change #3 - Kidney classification
KDPI
Be mindful that other independent acceptance criteria may conflict with KDPI
Examples:o candidate opts out of DCD but selects KDPI max of 60%
= will not see any DCD offers, even from KDPI 50% or less donors
o candidate selects max donor age of 55 and KDPI of 60% = will not see offers from 56 y/o donor with KDPI 36%
Acceptance criteria
Action: Update acceptance criteria
Action: Update consents
Current Priority New Priority
CPRA score at or above 80% receives 4 points
Moderately sensitized (CPRA 0-79%) receive zero points
CPRA scores of 20% or above receive points based on a sliding scale

Current NewKidneys allocated to candidates who are blood type identical to the donor when the donor has blood type O or B. Blood type B candidates are ineligible for A2/A2B offers.
Blood type B candidates that meet defined clinical criteria are eligible for kidneys from donors with blood type A2 or A2B.
Change #5 - Blood type eligibility
Action: Develop clinical criteria
Implementation
Phase I Phase II
• Data updates begin• New reports released• Calculators made available
• New allocation rules applied • Variances turned off• Payback system turned off
Summer 2014 December 2014
Summary: Member responsibilities
Communicate importance of early referral
Establish protocols for A2 and A2B donors to B candidates
Report/update data to calculate EPTS and waiting time
Review candidates to identify prior living organ donors
Establish KDPI acceptance criteria and update consents for KDPI>85%
Review waiting list for unacceptable antigens
Review “other” donor screening criteria
Educate candidates and potential candidates on changes
