Quality of Aspirate Specimen Yield Total Score -Jamshidi Manual Standard Device

The Quality of Aspirate Specimen Yield Total Score is a sum score using the 3 quality rating scales below. The Score range: 0 to 8; Higher scores mean greater quality.

Direct Smears- Cellularity:

0= obviously dilute, no good particles or adequate megakaryocytes (MK)

1. probably slightly dilute, particles and MK present
2. cellular, good particles; MK present on edge, smears reflect clot section cellularity

Particle Crush Smears: Evaluate presence of particles and quality of cellularity:

0= no particles

1. few particles; difficult to evaluate marrow cellularity and adequacy of MK
2. good particles; adequate material to evaluate MK
3. many particles, some large, with MK easily evaluated

Clot Sections: Evaluate quantity and quality of particles 0= insufficient or no particles for interpretation

1. few small particles; difficult to determine cellularity
2. several particles, good marrow cellularity
3. numerous particles (some large); easy to assess cellularity and cell composition

Level of Pain With Needle Insertion- Jamshidi Manual Standard Device

Subject reported level of pain with needle insertion (insertion of the bone marrow aspiration device, OnControl or Jamshidi, into the bone marrow space of the iliac crest) was reported by the patients for each procedure performed using the Wong-Baker FACES Pain Rating Scale Where 0 = no hurt and 10 = hurts worst. Higher numbers indicate greater pain.

Level of Pain With Needle Insertion- OnControl Power Ported Device

Subject reported level of pain with needle insertion (insertion of the bone marrow aspiration device, OnControl or Jamshidi, into the bone marrow space of the iliac crest) was reported by the patients for each procedure performed using the Wong-Baker FACES Pain Rating Scale Where 0 = no hurt and 10 = hurts worst. Higher numbers indicate greater pain.

Level of Pain With Aspiration - Jamshidi Manual Standard Device

Subject reported level of pain with aspiration (withdrawing the bone marrow aspirate specimen with syringe) was reported by the patients for each procedure performed using the Wong-Baker FACES Pain Rating Scale Where 0 = no hurt and 10 = hurts worst. Higher numbers indicate greater pain.

Level of Pain With Aspiration - OnControl Power Ported Device

Subject reported level of pain with aspiration (withdrawing the bone marrow aspirate specimen with syringe) was reported by the patients for each procedure performed using the Wong-Baker FACES Pain Rating Scale Where 0 = no hurt and 10 = hurts worst. Higher numbers indicate greater pain.

Time to Insertion - Jamshidi Manual Standard Device

Time recorded in seconds from contact of the device and the periosteum of the iliac crest to insertion of the needle through the cortex into the medullary space

Time to Insertion - OnControl Power Ported Device

Time recorded in seconds from contact of the device and the periosteum of the iliac crest to insertion of the needle through the cortex into the medullary space

Time for Aspirate Collection - Jamshidi Manual Standard Device

Time recorded in seconds from contact of the device and the periosteum of the iliac crest to removal of the needle from the medullary cavity following aspirate sample acquisition

Time for Aspirate Collection - OnControl Power Ported Device

Time recorded in seconds from contact of the device and the periosteum of the iliac crest to removal of the needle from the medullary cavity following aspirate sample acquisition
