Biopsy frequency, type, and decision to perform
| On what proportion of deceased donor kidneys evaluated for transplant by your center is a procurement biopsy performed? (N = 95) | % (n) |
|---|---|
| <10% | 5 (5) |
| 10 to <25% | 24 (23) |
| 25 to <50% | 35 (33) |
| 50 to <75% | 28 (27) |
| ≥75% | 7 (7) |
| What would you estimate is the relative influence of your transplant center vs. OPO on the decision to biopsy kidney offers evaluated at your center? (N = 94) | % (n) |
|---|---|
| 100% Transplant center | 13 (12) |
| 75% Transplant center/25% OPO | 24 (23) |
| 50% Transplant center/50% OPO | 34 (32) |
| 25% Transplant center/75% OPO | 24 (23) |
| 100% OPO | 4 (4) |
| Which of the following best describes your center’s approach to deciding when to request a kidney procurement biopsy? (N = 95) | % (n) |
|---|---|
| We request a biopsy of most-to-all kidneys considered for transplant | 20 (19) |
| We selectively request biopsy, based on donor characteristics | 71 (67) |
| We rely on the OPO policy/practice to determine the need for a procurement biopsy | 9 (9) |
| We almost never request a procurement biopsy and prefer to rely on clinical characteristics | 0 (0) |
| Does your center have a formal set of criteria for deciding when to perform a kidney procurement biopsy? (N= 94) | % (n) |
|---|---|
| Yes, and only kidneys that meet these criteria are biopsied | 31 (29) |
| Yes, but the clinician reviewing the offer can request a biopsy outside of criteria | 41 (39) |
| No, the decision to biopsy is made without reference to formal criteria | 28 (26) |
| What percentage of procurement biopsies for kidneys evaluated at your center are needle core vs wedge biopsies? (N = 94) | % (n) |
|---|---|
| 100% Needle core | 10 (9) |
| 75% Needle core/25% wedge | 11 (10) |
| 50% Needle core/50% wedge | 23 (22) |
| 25% Needle core/75% wedge | 22 (21) |
| 100% Wedge | 34 (32) |
| What percentage of procurement biopsies for kidneys evaluated at your center are processed as frozen section vs. permanent section? (N = 92) | % (n) |
|---|---|
| 100% Frozen section | 47 (43) |
| 75% Frozen section/25% permanent section | 10 (9) |
| 50% Frozen section/50% permanent section | 13 (12) |
| 25% Frozen section/75% permanent section | 21 (19) |
| 100% Permanent section | 10 (9) |
