Table 2.

Summary of the sequence of steps carried out in order each day for each KPD&DD simulation. All steps except step 3 are also carried out in each KPD-only simulation.

After the initial pool is created, each simulated day for the KPD&DD consists of the following steps.

  1. Each active pair exits the KPDP with probability 0.0005

  2. Arriving pairs/NDDs are added to the pool.

  3. **DD-CIKs arriving that day are allocated to the pool if possible. The LD associated with the candidate receiving the DD-CIK donates to the DD waitlist (within a few days).

  4. At the end of every 10th day a match run maximizing the expected numbers of transplant is carried out, chains and cycles are selected and marked by a transplant due date of 9 days after the current time, associated pairs and NDDs are removed from the pool and made inactive/awaiting transplant for 9 days.

  5. Nine days after a match run,
    1. The viability of all transplants in selected chains and cycles is determined.
    2. Transplants are carried out as possible.
    3. Untransplanted pairs and NDDs return to the pool and matches are updated.

  6. NDDs/BDs who are untransplanted for 90 days donate to the DD waitlist.

This step is omitted in a KPD-only simulation.
