Bone marrow biopsy quality as quantified by biopsy cylinder length and diagnostic usefulness is improved with a powered bone marrow biopsy device in comparison with a manual device.

Condition Intervention
Bone Marrow Biopsy
Device: OnControl BM-Biopsy system

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: a Prospective Randomized Controlled Trial Comparing a Powered Bone Marrow Biopsy Device With a Manual System

Further study details as provided by University Hospital, Basel, Switzerland:

Primary Outcome Measures:
  • Diagnostic usefulness (yes/no) of biopsy cylinder [ Time Frame: within 1 week of biopsy ] [ Designated as safety issue: No ]
    The bone marrow biopsy cylinder is assessed by a pathologist who rates either "diagnostic" or "non diagnostic"

Secondary Outcome Measures:
  • patient pain during procedure [ Time Frame: day 1 (two time points) and day 3-5 ] [ Designated as safety issue: No ]
    patients underdoing biopsy rate the pain during, 15 min after and 3-5 days after the proceedure

Enrollment: 60
Study Start Date: May 2011
Study Completion Date: December 2011
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
