Medical Board Policies
- Match Offer Selection - The NKR shall select match offers based on the
following scientific and objective criteria:
- When adequate time is available, match offers shall be selected to facilitate the most possible transplants except when Advanced Donation Program (ADP) patients, or difficult to match pairs can be matched. ADP matches will be prioritized over paired recipient matched when cPRAs are similar.
- When time is limited (e.g. NDD has a limited timeframe, compatible pair
has a limited time frame, etc.), match offers with the greatest probability to make it
to transplant within the allotted timeframe shall be selected. In these cases priority
shall be given to factors such as:
- Cross match has already been completed and is acceptable.
- Donor has already been accepted in the pre-select function.
- Fast track center (can go from offer to transplant in 3 business days).
- When multiple potential match offers yield similar numbers of transplants, in
addition to the considerations outlined in #1 & #2 above, the following priorities shall apply:
- First Priority: Children.
- Second Priority: Patients at centers with the highest Center Liquidity Contribution score.
- Third priority: Patients with the longest wait times in the NKR system.
- Ending Chains - The NKR shall end chains according to the following priorities:
- To former NKR paired exchange donors in need of a kidney transplant.
- To paired or ADP patients involved in real-time swap failures where the donor has donated but the patient did not get a kidney.
- To ADP patients who are ready for a transplant according to the following priorities:
- First priority: Pairs who opted into the ADP program to repair a swap.
- Second priority: Longest time interval from donor donation.
- To paired or ADP patients transplanted in NKR swaps who experience graft failure within 90 days of the transplant subject to the conditions below:
- Paired or ADP recipients whose center reports the issue in the NKR system and provides pictures of the kidney within 8 hours of kidney receipt, will be provided a replacement kidney, if the Surgical Committee following review of the data and circumstances clearly and confidently determines the graft failure was a result of an impaired kidney that was delivered to the recipient center.
- Paired or ADP recipients whose center reports the issue in the NKR system after 8 hours but within 90 days of kidney receipt, may be provided a replacement kidney if the recipient surgeon presents the case and the Surgical Committee determines that the graft failure was clearly and confidently a result of an impaired kidney that was delivered to the recipient center.
- When a replacement kidney is provided, the Surgical Committee may choose to transfer the -1 NCS deduction from the recipient center to the donor center.
- To 'O' blood type NKR patients at Partner Centers who experience primary non function upon case review and approval of the Surgical Committee. Each Partner Center is eligible for one 'O' chain end kidney per year.
- To CHIPs at Member Centers with Net Chains Started (NCS) > 0 that have accepted the donor in preselects.
- To NKR Member Centers with NCS > 0 who have declined less than 1 chain end offer per chain start, in the past 12 months.
- To NKR Partner Centers that have the highest 'target' number which is determined by
((4.0 x chains started with 'O' family voucher donors in the past 2 years) +
(2.0 x chains started with 'Non-O' family voucher donors in the past 2 years) +
(center's current Net Chain Started score)) Example:
- 3 chains started with O Family Voucher Donors in the past 2 years = 12 (3 X 4.0) +
- 4 chains started with Non-O Family Voucher Donors in the past 2 years = 8 (4 X 2.0) +
- The current NCS score of -4
- = Target Score = 16 (12 + 8 + -4)
- Photographing Kidneys - Pictures of all shipped kidneys shall be sent to the recipient surgeon after a phone call or text to the recipient surgeon, both within 1 hour of the completion of the surgery. Pictures shall be taken on the back bench after flushing and shall include:
- Allograft parenchyma (demonstrating kidney is well-flushed 'blanched')
- Any abnormalities (such as cysts, lesions, capsular tears, surgical injuries, etc.)
- Renal hilum (highlighting vessel length, multiple vessels and/or ureters). If the kidney is declined after delivery to the recipient center, the recipient center must send pictures of the kidney to the NKR within 2 hours of receipt of the kidney.
Managing Real-Time Swap Failures
- A real-time swap failure occurs when a swap fails after one or more donor surgeries have begun. When a swap fails in real-time, NKR shall:
- First attempt to cancel or reschedule the swap.
- If any of the donor surgeries cannot be aborted, then the NKR Member Centers shall proceed with the swap and the NKR shall work to end a chain to the patient in the failed swap that did not receive a kidney.
- The center caring for the patient that did not get a kidney must remove all restrictive preferences and accept all viable donors via the donor pre-select function unless the center determines that it is in the patient's best interest (e.g. pre-emptive transplant) to wait longer by declining viable potential donors in order to get a better match.
- If the patient that did not get a kidney is hard to match (e.g. NKR cPRA > 95%), the NKR may not be able to find a compatible donor for that patient. This risk must be disclosed in the Member Center's informed consent documentation that is signed by the patient and the donor.
- In the calculation of "net chains started", the donor center is accountable for the chain break.
- The donor center shall cover all costs related to the donor surgery and donor care.
- If the real-time swap failure was caused by the recipient center's decline of the kidney after the start of the donor surgery, the kidney will remain at the donor center or will be shipped back to the donor center; for transplant into a wait-listed patient, voucher holder or a paired recipient.
- If the kidney does not remain at the donor center, the NKR will cover the kidney shipping cost.
- If a charter flight is requested to expedite the transport of the kidney back to the donor center, the donor center will pay for the charter flight.
- The donor and recipient surgeons may be required to review the case with the Surgical Committee.
- Advanced Donation Program - The Advanced Donation Program (ADP) is a paired exchange separated in time. This program allows medically and psychosocially acceptable donors to donate their kidney before their Intended Recipient receives a kidney at the end of a chain.
- Your center must be approved by NKR to participate in the Advanced Donation Program.
- An ADP donor that starts a chain does not increase a Member Center's Net Chains Started score.
- There is no guarantee that the patient(s) can be matched or transplanted.
- The ADP donor and intended recipient(s) must complete and return the consent forms to apply for ADP participation.
- ADP forms for ADP donors must be uploaded to the NKR website prior to activation.
- ADP forms for ADP voucher holders must be uploaded prior to the ADP donor donating in order to be eligible.
- ADP pairs are subject to the review of the NKR prior to the advanced donor's donation.
- We encourage you to read the published Advanced Donation Program case reports.
- An ADP donor may identify one intended recipient for a Standard Voucher or up to five intended recipients in their immediate family for Family Vouchers.
- An ADP Recipient may have up to five ADP Donors.
- The ADP donor and Intended Recipient can be at different centers, but those centers must both be ADP participating centers.
- Member Center Suspension - The NKR reserves the right to suspend Member Centers from inclusion in match runs if the Member Center is deemed to have introduced safety risks or is in violation of Member Center Requirements. Suspension shall continue until appropriate corrective action plans have been submitted to, and approved by, the Medical Board. Should the Member Center wish to present the corrective action plan to the Medical Board, a conference call with the Medical Board will be scheduled.
- Surgical Review - If the Recipient center requests an investigation then the NKR Surgical Committee will review the case in detail.
- COVID Donor Testing - Member Centers shall screen all NKR donors according to the following process:
- Only asymptomatic donors with low risk of COVID exposure may proceed with kidney donation.
- Screen donors utilizing donor center and CDC Guidelines.
- All donors must complete a COVID PCR swab test 1-2 days prior to surgery.
- If the donor tests positive, the donor surgery will be delayed or cancelled.
- PCR test results must be uploaded to the NKR systems by 15:00 ET the day prior to surgery to provide visibility of the test results to the recipient center prior to the kickoff call.
- Only asymptomatic donors with low risk of COVID exposure may proceed with kidney donation.

- If an Exchange Coordinator becomes aware of a situation that puts the swap at risk he/she must immediately send an email to Member Services with notification of the situation and then contact the NKR Swap Manager via phone. If the Swap Manager cannot be reached via phone the Exchange Coordinator must alert their NKR Center Liaison or any other member of the NKR staff.
- If a coordinator or center representative is not present on a kickoff call, and the risk notifications outlined in this section have not been satisfied, the NKR will proceed with the swap as scheduled.
- If a center experiences an issue that is reported in the quarterly swap failure report, the primary or backup coordinators must attend the National Coordinator call to review the root cause and corrective action related to the swap failure.
- Primary and backup coordinators shall:
- Donor and recipient surgeons at a Member Center shall proactively organize their schedules to ensure surgical capacity is available for KPD procedures on Tuesdays, Wednesdays, and Thursdays with 3 weeks advance notice.
- The donor surgeon must call the recipient surgeon within an hour after completion of the donor nephrectomy. If the donor surgery went well and there are no concerns, and the recipient surgeon is not available, a voice mail will suffice. If there are concerns, a second attempt should be made to reach the recipient surgeon. If the second attempt fails, then the recipient center coordinator must be contacted to pass along the information. The surgeons must speak when both are available.

- When a match offer is received, the following communications shall take place:
- Center contacts both donor and recipient to ensure pair is ready for surgery.
- Center reviews the virtual cross match & CT scan on NKR site.
- Center records match offer decision in NKR site
- Centers shall respond to match offers by the match offer deadline which is generally within one business day of the offer.
- When a match offer is accepted, the pair must be immediately deactivated in all other exchange programs, including internal programs.
- When a match offer is accepted, the recipient's chart must be reviewed for updates and creatinine must be immediately rechecked for predialysis patients.
- Centers are encouraged to deactivate patients in the deceased donor system immediately following the logistics calls for NKR swaps.

- When a match offer is received, the following communications shall take place:
- HLA, Cross Matching & Serology Tests
- Centers shall accurately enter all donor and recipient antigens, and all recipient avoids including low level DSA's.
- The NKR provides confirmatory ABO typing for all donors, we also include subtype for A, and AB donors.
- If a discrepant ABO or subtype is reported between the center and NKR then it is the responsibility of the donor center to retest the donor and notify NKR of the results. For any donor listed as an unknown subtype the NKR will determine the subtype and update the donor profile.
- The NKR provides confirmatory HLA typing, including enhanced resolution typing.
- When new pairs are first made exportable, the antibody screenings used to determine the avoids shall be current (within 30 days).
- Centers shall conduct antibody screenings every 90 days for sensitized patients and update the avoids appropriately.
- Recipient centers are expected to report XM results for Cryo preserved samples no later than 15:00 ET on the fourth business day from the day the cryo cells are received. (e.g. If the cryo cells arrive on Tuesday, the results must be recorded in the NKR no later than 15:00 ET Friday)
- When centers receive a potential match email centers shall record clearance of potential matches according to the following procedure:
- Donor blood for serology tests must be shipped to the NKR lab no later than 9 days before surgery and the test results uploaded to the NKR site no later than 6 days prior to the donor's target surgery date to ensure the donor can proceed.
- Member Centers must have the ability, through their own or NKR lab, to provide serology test results in three calendar days or less.
- If a center reports an unacceptable cross match, the lab director shall review the root cause and corrective action plan on the National Lab Director call.
- The NKR uses three types of Cross Matches:
- Exploratory cross matches are requested by a recipient center prior to a match offer to confirm a donor is compatible with a sensitized recipient.
- Screening cross matches are required once all match offers in a swap are accepted; this cross match will be commenced by NKR.
- Final cross matches are requested by the recipient center 1-2 weeks prior to surgery (cryo preserved samples cannot be used for Final cross matches).
- When fresh blood is used, the following cross matching procedures are utilized according to the timeframes in the
- Donor center draws and ships donor blood to the recipient center/lab.
- Donor blood tubes are labeled according to the instructions.
- Recipient center receives the blood, performs the cross match and records the results on the NKR web site.
- When cryo preserved NUCS are used, the following cross matching procedures are utilized according to the timeframes in the flowchart below:
- Donor center ships cryo preserved NUCS to the recipient center/lab.
- Cryo preserved NUCS are labeled according to the instructions.
- Recipient center receives the NUCS, performs the cross match and records the results on the NKR web site.
- NUCS for exploratory cross matching should only be used for the cross match so that multiple NUCS are not needed. Exploratory cross match testing should not include other testing such as:
- Donor typing
- Multiple Sera
- Multiple Platform
- When using cryo for a screening crossmatch additional NUCS may be requested, if needed, to perform additional tests.
- Shipping Kidneys
- To reduce the inherent shipping risks related to connecting commercial flights, an on board courier must be utilized for all connecting flights.
- Packaging supplies include:

- If the packaging provider does not provide the packaging services adequately then they will not be paid for the inadequate packaging service. Inadequate service includes, but is not limited to, not responding to a RCCAP request within 2 business days.
- GPS Tracking:
- It is the responsibility of the recipient center coordinator to monitor the GPS device.
- Donor Centers will receive a GPS device, from NKR approximately 1-5 business days before donor surgery. The device requires no activation.
- The GPS device must be packed on top of the ice or inserted between the shipping containers, unless an On Board Courier is transporting the kidney.
- If the kidney is being transported via On Board Courier:
- The GPS device should be given to the driver, not packed in the box with the kidney.
- A letter should be given to the courier explaining what is in the box, as well as instructions not to open the box. Click here for a sample letter.
- Coordinators at both the donor and recipient centers will receive periodic alerts to their cell phone and Email, giving the location of the GPS beacon. Once airborne at an altitude of approximately 5,000 feet and higher, the Last Known Location will no longer update.
- The coordinator must contact the swap manager immediately if there are any inconsistencies between the GPS readings and logistics plan.
- Recipient Centers will receive pre-paid return packaging from NKR for the return of the GPS.

- Click on the icon that displays the current location to view a breadcrumb trail of the scenario.
Member Center Guidelines
- Living Donor Evaluation- The
purpose of the evaluation and consent of the living donor is to maintain the highest
degree of safety and transparency for the living donor. As a baseline, the
Guidelines and the OPTN standards will be used for donor evaluations. Donor evaluations must be completed before a donor can be activated in the NKR. The donor center evaluation policies should be followed by the donor center and not be directed by the recipient center since the donor center is responsible for donor care. The receiving center may ask for additional testing to clarify issues related to the quality of the kidney or to ensure there is minimal risk of infectious disease transmission. Requests for additional donor testing should be made immediately upon cross commencement in order to avoid late stage donor declines and failed swaps. As of 11/1/17 the NKR began purchasing donation insurance for all donors who donate a kidney through NKR.
- Member Centers are encouraged to use the NKR Donor Chart format when uploading a donor chart.
- Basic Evaluation:
- Complete history and physical.
- Height, weight, BMI.
- BP at two different settings on different days.
- General laboratory to assess:
- hematologic status.
- fasting lipids and glucose.
- liver status.
- Age appropriate evaluation for cancer.
- Donor work-ups must be repeated in their entirety, every 12 months, except for CT angio, unless the first CT angio was abnormal.
- Kidney Evaluation:
- Urinalysis with microscopy.
- Urine culture if indicated.
- 24 hour urine for albumin excretion and creatinine clearance.
- Anatomic Testing for anatomy definition.
- If a donor GFR reading is below 85, the center will perform a nuclear medical GFR test to confirm the donor's GFR.
- The minimum acceptable GFR for donors age 60 and under is 80. The minimum acceptable GFR for donors over age 60 is 75.
- If there is > 10% difference in donor kidney size (between the two kidneys) then the smaller kidney will be offered for donation.
- Spot Urine albumin: creatinine ratio measurements may be used instead of 24h proteinuria at centers that use nuclear medicine GFR measurement. The acceptable range for urine albumin: creatinine ratio is less than 30 mg/Gm.
- Tuberculosis screening:
- Chest X-Ray (CXR).
- Criteria for high risk donors: (based on history and physical)
- Birth or residence in a TB endemic country.
- Close contacts of individuals with TB (Household or family members).
- Donors who work or have resided in homeless shelters, correctional facilities, nursing homes, or hospitals.
- History of IV drug use.
- Evidence of granulomas or healed TB on CXR.
- For donors meeting the criteria for high risk we recommend Interferon-gamma release assays (IGRAs) or tuberculin skin test (TST).
- Recipient center may choose to have additional testing performed at time of match offer acceptance.
- Infectious disease screening:
- HIV 1,2.
- HBsAg, HBcAB, HBsAB.
- Depending upon time of year and location associated risk:
- Trypanosoma cruzi.
- West Nile Virus.
- Suggested evaluation for donors at risk for metabolic syndrome or diabetes:
- Uric acid.
- Glucose tolerance testing.
- Stone Disease:
- If multiple stones or nephrocalcinosis are not evident on CT, an asymptomatic potential
donor with history of a
single stone may be suitable for kidney donation if they have:
- No hypercalcuria, hyperuricemia, or metabolic acidosis.
- No cystinuria, or hyperoxaluria.
- No urinary tract infection.
- An asymptomatic potential donor with a current single stone may be suitable if:
- The donor meets the criteria shown previously for single stone formers.
- The current stone is less than 1.5 cm in size, or potentially removable during the transplant.
- Stone formers who should not donate are those with:
- Nephrocalcinosis on x ray or bilateral stone disease.
- Stone types with high recurrence rates, and are difficult to prevent.
- If multiple stones or nephrocalcinosis are not evident on CT, an asymptomatic potential donor with history of a single stone may be suitable for kidney donation if they have:
- Post Donation Follow Up and Donor Complications - A post-donation follow-up should follow the policy described in CMS Pub. 100-02, Chapter 11, section 140.9, including:
- The UNOS required 6 month, 1 year, 2 year follow-up should not be included in the organ acquisition cost center or separately billed to Medicare.
- Follow-up care rendered by a physician who performed the operation is included in 90 day global. After 90 days, charges are billable to recipient's Medicare number.
- For follow-up care rendered by physician other than operating physician, bill to recipient's insurance for up to 3 months unless directly related to complications of the donation.
- Charges are routed to Organ Acquisition for up to 90 days or up to 6 months if potentially related to complications.
- After these time periods, facility charges may not be allowable on the Medicare Cost Report.
- In all of these situations, the donor is not responsible for co-insurance or deductible.
- Good Samaritan Donors - A Good Samaritan
Donor is also known as a Non Directed Donor (NDD). They are donors that want to donate to a
stranger and may want to start a chain of transplants. Guidelines for Member Centers working with
Non Directed Donors are as follows:
- NDD's should be made aware of their donation options. They can either start a chain
of transplants or donate to a single recipient on the centers waitlist.
- If an NDD donates to someone on the center's wait list, the scheduling of the surgery may be easier for the NDD.
- If an NDD starts a chain of transplants, they will generally help more people get transplants.
- It often requires a long wait time for "A" and "AB" blood type NDD's to start a chain of transplants.
- It is the responsibility of the Center to educate the NDD. Centers should fully explain the donation process to the donor and should let them know what to expect, before, during and after surgery.
- Centers should ensure that the NDD can get appropriate time off from work.
- Centers should determine the NDD's availability for surgery and accurately enter it into the NKR system.
- Centers should ensure the NDD is updated on a timely basis regarding where they are in the workup process, results of all medical tests, when they are activated in the NKR program and the status of chains that the NDD is facilitating.
- The Center should inform the NDD that there may be financial support available to assist them in the donation process if they qualify.
- NDD's should be made aware of their donation options. They can either start a chain of transplants or donate to a single recipient on the centers waitlist.
- Bridge Donors - A bridge donor is any paired donor that donates after their paired recipient
receives a kidney transplant in a swap. The bridge donor serves as a
"bridge" to the next cluster of transplants in a chain and generally has the ability to
be with their friend or family member while they recover from transplant surgery, before
they themselves go through kidney donation surgery. Bridge donor guidelines are as
- Bridge donors should be prepared to donate between one week and three months of their paired recipient's surgery with no significant schedule limitations.
- Bridge donors must have no significant medical risks that could prohibit them from donating.
- The donor center must be confident that the bridge donor will follow through with donation.
- New centers may want to complete at least three exchange transplants prior to identifying donors as bridge donor candidates.
- Member center guidelines for educating and evaluating donors to qualify a bridge
donor candidate should include:
- Discussions regarding the possibility of being a bridge donor should begin at initial donor evaluation and continue throughout the process.
- If there is any hesitation with the potential bridge donor, the center should decline offers to bridge the donor and identify the donor accordingly in the NKR donor profile.
- When asking a donor to bridge, an in-person discussion should occur and include the donor's support person.
- Member centers must maintain frequent contact with bridge donors.
- Member centers should advise bridge donor candidates to discuss their commitment to paired exchange with their employer early in the process and again when they become a bridge donor.
- Member centers must clarify any time constraints with bridge donor candidates and advise donors of the need for immediate notification of any unexpected travel plans and availability during that time for blood draws.
- Member centers should re-educate donors and reconfirm their availability prior to accepting the donor for a bridge position in a swap.
- Advanced / Voucher Donors -
- Standard Voucher Donors are encouraged to give a minimum 30 day window for their donation range.
- The ADP donor must complete and return the consent forms to apply for ADP participation.
- An ADP donor may identify one intended recipient for a Standard Voucher or up to five intended recipients in their immediate family for Family Vouchers.
- Up to five ADP donors can identify the same intended recipient.
Center Liquidity Contribution Program
The Center Liquidity Contribution (“CLC”) program scores Member Center based on their contribution to the pool liquidity (i.e. NDDs and pairs entered) and the “payback” of the center's contribution (hard to match pairs matched & transplanted) in the form of match offers. Top scoring CLC centers are given priority. To view the CLC scoring guide click this link.
Remote Kidney Donation allows someone who wants to donate a kidney to a friend or family member in a distant city without requiring the donor to travel to the transplant center in the distant city. Remote donation utilizes proven logistics systems pioneered in kidney swaps by the National Kidney Registry over the past decade to safely transport the kidney from the donor's local hospital to the transplant center in the distant city. Click here for more info.
Below is a map of the centers that participate in the remote donation network.
Donor Protection Program
- Donor Complications - Medical complications that arise as a direct result of the donation are handled as follows:
- If a member center executes the donor protection Addendum they agree to pay for all Uncovered Complications (Donor Complications that are not reimbursable by the recipient insurance, recipient center or recipient) for all donors that undergo donor surgery at the Member Center' Hospital.
- If a Member Center does not execute the Donor Protection Addendum, they will be billed for donor protection according to the Standard Reimbursements Section to accumulate a fund for uncovered donor complications. The fund is intended to protect donors at centers that have not signed the donor protection addendum. The donor protection fund will be capped at $1 million. Donor claims in excess of the amount in the fund will not be covered.
- If a Member Center records Medicare as a patients primary or secondary insurance and the patient does not complete their Medicare enrollment before the transplant or at the time of transplant, the recipient center shall pay for all Uncovered Complications for the donor who gave a kidney to the patient with the inaccurate Medicare designation.
- Donor Follow Up - Shall be the responsibility of the center that performs the donor nephrectomy.
Donor Automated Screening & History (DASH)
The DASH system is a streamlined donor intake platform which provides a valuable time saver to the transplant center and helps centers handle a large volume of donor candidates. The flow chart below details the services:
Donor Care Network
The Donor Care Network (DCN) Centers of Excellence (COE) are a network of elite transplant centers that have agreed to the DCN commitments and are supporting programs that focus on the highest standards of living kidney donor support and service. The DCN COEs are represented in the map below.
The Donor Shield Program Centers offer protections to donors whether they donate directly to their recipient or through an NKR exchange. All donors who donate at a Donor Shield Center, represented in the map below, will receive the following protections already offered to all NKR donors:

Medicaid / Medi-Cal to Medicare Conversion Guide
- If the patient is on dialysis and has the requisite work history, then Medicare enrollment is granted based on dialysis prior to transplant.
- If the patient is not on dialysis and has the requisite work history, then the center should assist the patient with the process for Medicare enrollment at the time of transplant and communicate a billing hold to current payor(s) until Medicare is effective. Additionally, the donor center must agree to hold billing for all professional fees until recipient's Medicare policy goes into effect (a billing hold is better than billing and reimbursing the current payer and then rebilling Medicare).
- Centers must assist patients with obtaining documentation of Medicare entitlement so that the center can complete a CMS Form 2728 Medical Evidence Report (MER) in order to implement Medicare coverage.
- The recipient's Center must provide a completed CMS 2728 Form to the donor center upon match offer acceptance.
- Medicare entitlement should always be confirmed prior to transplantation so that the patient is aware of any potential out of pocket expenses, the need to choose RX coverage and other related financial issues.
- When entering patient avoids, include all low-level Donor Specific Antibodies (DSAs).
- By entering all DSAs, the patient will have a more accurate cPRA, increasing their matching priority in the NKR.
- By entering all DSAs, you will increase the odds that NKR will find a better matching donor for your patient.
- By entering all DSAs, you will reduce the risk of a swap failure caused by unexpected unacceptable XMs.
- If you patient has an NKR cPRA > 95% (hard to match), use the “Avoid Conflict” tab in the preselect screen to find additional matching donors.
- Review all potential donors with one or more avoid conflicts in the Avoid Conflict tab.
- Override avoid conflicts by accepting donors with low level DSA's that, in combination with other DSAs, will not cause an unacceptable XM.
- Request cryo cells and perform rapid exploratory XMs on those borderline donors where the XM results are not predictable.
- Center Liquidity Contribution (CLC): Centers that enter “O” NDDs and ABO favorable pairs (“O” donors with “A”, “B”, or “AB” recipients) will receive CLC points which will prioritize the patients at that center. A positive CLC score has the greatest impact on shortening wait times for pairs with unfavorable blood type combinations (“O” recipients with “A”, “B”, or “AB” donors).
- Multiple Paired Donors: Many centers have unfavorable blood type combination that wait a long time for a match offer. If your patient has another donor, you can increase their odds of receiving a match offer by entering the second donor into NKR but the most powerful way to get these patients transplanted is for the center to achieve a positive CLC score.
- One criterion that is used to prioritize potential matches is wait time. Wait time is accrued for days that the pair is "exportable" and is NOT based on registration date. The sooner a center can make a pair exportable and the longer the pair remains exportable, the more wait time the pair will accrue.
- Abundant A2 donors: If you have an “O” recipient with titers acceptable for an A2 donor, you can generally get an immediate match if you set the patient filed to allow for A2 donor matches.
- Many donors are declined on anatomy, blocking potential matches. In some cases, these declines can be overcome by offering the other kidney which may not exhibit complex anatomy. This can be accomplished by selecting the appropriated options in the donor record.
- Compatible pairs: An A, B or AB patient with a compatible O donor will find a match immediately and can afford to be very selective when accepting potential donors while other compatible pair blood type combinations (e.g. O to O, A to A, etc.) may not be matched as quickly and therefor may have longer KPD wait times.
- The NKR can improve the donor-recipient match for compatible pairs which can improve patient outcomes while facilitating transplants for many other incompatible pairs. Click on the following link to learn more https://www.kidneyregistry.org/compatible_pairs.php
- Centers should consider using charter flights to ship kidneys when no direct flights are available. An analysis of transport options showed that for a nominal 18% average increase in costs for a charter compared to an on-board courier, transit times are reduced from an average of 11 hours to less than 5 hours.
- If you have a patient that has not received a match offer and you are wondering if there is an issue with the paired donor, that is causing centers to decline the donor, look at the declines tab in the donor profile. This tab provides an accounting of the donor declines and the reasons for each decline.
- Adequate Surgical Capacity Will Help Your Patients Get Matched & Transplanted - NDDs and compatible pairs often have tight timeframes for surgery, limiting swap scheduling options. Many patients that are matched in FAST TRACK swaps are losing out on transplant opportunities due to the lack of surgical capacity at some centers. Centers can get more patients transplanted by increasing surgical capacity by
- Coordinating surgeon vacation/travel schedules to ensure coverage on NKR target swap days which are Tuesday, Wednesday & Thursday.
- Cross training donor and recipient surgeons so that one surgeon can do both surgeries.
- Hiring more surgeons.
- If your patient has an NKR cPRA of 99% or less and all DSAs have been listed as avoids so that the cPRA is accurate, this patient should not require desensitization and should be matched/transplanted in 6-12 months.
- If your patient has an NKR cPRA of 100%, they will likely require desensitization to get matched/transplanted in the NKR.
- If your patient has an NKR cPRA of 99% - 100% and they have been waiting more than a year for an NKR match, they may require desensitization to get matched/transplanted in the NKR.
Failed crossmatches can be devastating for NKR chains because one failure often affects many potential transplants. On average, a single unexpected crossmatch failure in NKR impacts 8 surgeries. Crossmatch failures are also costly when tests at other centers are performed for patients who cannot proceed to transplant. Although some crossmatch failures are unavoidable, most can be prevented by the HLA laboratory by playing a proactive role in donor selection. The NKR has developed tools to preview potential donor matches and perform exploratory crossmatches on potential donors for sensitized patients. Using these tools will improve your patients' chances for transplant and will reduce unexpected crossmatch failures. Good communication and understanding between the laboratory, coordinators, physicians and surgeons is a key to success in paired exchanges.Establish an understanding of your crossmatch results with the transplant team
- Convey the importance of avoiding or at least reporting potential sensitizing events to the transplant team and to the laboratory.
- Patients should notify the transplant team prior to being transfused, having surgery, etc. Retest patients whose antibody profiles may have changed.
- Review patients with special requirements for compatibility (e.g. children, patients unable or unwilling to accept a donor with potential incompatibilities).
- Establish clear crossmatch thresholds with your transplant team.
- Borderline positive or negative results may change with retesting.
- Flow cytometry results are semi-quantitative, rather than a dichotomous positive or negative, flow values provide an indication of increasing risk.
- Anticipate confounding crossmatch results.
- Screen for IgM or autoantibodies.
- Treat patient sera with DTT or EDTA to reduce prozone effects in solid-phase tests.
- Test sera at dilution to identify weak antibodies or antibodies at saturation.
- Be careful enrolling patients in KPD with non-HLA antibodies that may preclude a transplant.
- List all DSAs AND
- List more low level avoids for easy-to-match pairs (cPRAs < 95%) since they will have many potential donors.
- List more low-level avoids for patients who will not tolerate aggressive immunosuppression, plasmapheresis or who otherwise require a completely DSA-free transplant.
- Review donors with one avoid HLA antigen in the avoid conflict tab.
- Determine whether desensitization is feasible for specific incompatibilities.
- Review ABOi donors for 100% CPRA patients (ABOi is often less difficult than desensitization for HLA).
- Contact the donor center laboratory to ask for donor typing details in needed.
- Use tools like NMDP's website (http://www.haplostats.org/haplostats?execution=e1s1) to predict allele types based on high resolution haplotype frequencies.
- Use tools like the epitope registry (http://www.epregistry.com.br) to evaluate allele reactivities in the context of shared potential epitopes.
- A weak DSA.
- Multiple low-level DSAs.
- Cw, DQ or DP DSAs with uncertain crossmatch potential.
- Allele-specific antibodies not likely to react with a selected donor.
- Exploratory XMs should be requested as soon as the potential donor becomes available via preselect.
- Exploratory XMs using NKR supplied cryo cells should be completed in 1-day.
