Guidance

AT RECRUITMENT

Acceptable

- For PBSC - if BMI less than, or equal to, 40.0.

- For BM - if BMI less than, or equal to, 35.0.

AT VT

Acceptable

- For PBSC - if 45kg and over (or 7st 1lb) and BMI less than, or equal to, 40.0 (If BMI 40-43 discuss with MO).

- For BM - if 45kg and over (or 7st 1lb) and BMI less than, or equal to, 35.0 (If BMI 35-40 discuss with MO).

If a donor is < 45kg, the VT team need to ask the TC what the patient weight is, and then discuss with a MO.

Potential donors with BMI >35-40 may have complications prior, during and after the harvest:

- PBSC - poor venous access, need of central line insertion (and its subsequent complications). Risk is less clear than BM so greater discretion may be used.

- BM - should be carefully assessed for additional anaesthetic risk factors (e.g. cardiovascular, respiratory and endocrine disease). If no additional risk factors donor may at discretion of MO proceed to medical assessment when an anaesthetic opinion is mandatory before donor can be cleared to donate. At medical donor must also be examined to decide whether a BMH is technically possible. The collection centre must be alerted to this additional requirement before donor is sent to medical.

Justification

BMI is the most reliable tool to assess the body composition within the scientific community, and it is the criteria to based our decision upon. It should be strictly followed at recruitment although donors outside these limits at work-up should be discus with the medical officer who may allow them to proceed after discussion with the Medical Director.
