DonorNet Data

1
DonorNet Data

• Based on system data between
• May 1 July 6, 2007

2
COHORT

• All electronic notifications from May 1, 2007,
  through July 4, 2007
• EXCLUSIONS
• Offers made electronically by the Organ Center
• Non-electronic offers (made by either an OPO or
  the Organ Center)
• Import matches
• Matches not yet closed

REPORTING CONVENTIONS

• In this report heart matches and heart-lung
  matches are reported separately for many of the
  tabulations. A heart may be placed off of either
  type of match a heart-lung may be placed off of
  a heart-lung match or in some cases from a lung
  match
• The tabulations may include both donors and
  potential donors. Due to the recent nature of
  these tabulations, it is not always possible to
  determine if organs have been recovered (which
  determines donor status.)
• Broadcast notification Defined as all electronic
  offers that were sent out simultaneously this
  may include a single center or multiple centers.
  Multiple broadcast notifications may be sent out
  on one match.

4
NOTE Due to the very recent nature of these data
and the short time period included in the cohort,
the results should be considered as purely
preliminary and are subject to change based on
future data submission or correction.
Conclusions should be made with caution.
5
OVERALL ACTIVITY

• For donors/potential donors in cohort with at
  least one electronic notification

This may include cases where the center
exceeded notification time or evaluation time.

PLACEMENT/ PLACEMENT EFFORTS
34
PLACEMENT OUTCOME FOR ORGANS WITH ANY ELECTRONIC
NOTIFICATIONS 5/1/07-7/4/07
This table is based on matches by organ type.
It does not reflect the recovery/transplant rates
by each organ type. Heart-lung matches may
result in transplants of the heart-lung bloc or a
heart alone.
INTERPRETATION There were 964 donors/potential
donors from whom a kidney match was run. Of
these 964, 731 (76) had at least one kidney
transplanted. Of the remaining 233
donors/potential donors with a kidney match run,
129 had least 1 electronic offer made outside of
the local DSA and 104 did not.
35
PERCENTAGE OF DONORS WITH MATCHES RUN PRE- AND
POST-DONORNET
The percentage of donors from whom a match was
run is fairly similar during the two periods for
all organ types.
36
MATCH RUNS WHERE MATCH WAS EXHAUSTED (ALL
CANDIDATES RECEIVED OFFERS)

• For every match organ type there were more
  matches exhausted post-DonorNet than prior to
  DonorNet.
• For most organ types the median number of
  candidates on the exhausted matches was similar
  between the two eras.
