Evaluating Effectiveness of Powered Drill Bone Marrow Biopsy

Not Applicable
Completed
Conditions
Plasma Cell Myeloma
Interventions
Device: Jamshidi needle
Device: Power drill
Registration Number
NCT03078452
Lead Sponsor
Emory University
Brief Summary

Since the introduction of the Jamshidi needle in 1971, new advances in bone marrow sampling have not been seen. In 2007, a new battery-powered bone marrow biopsy system was developed. This technology, using a battery-powered drill to operate the needle accessing the posterior iliac bone, was approved by the Food and Drug Administration (FDA) and is currently commercially available.

Few randomized controlled trials (RCTs) have compared the use of the battery-powered bone marrow biopsy system to the Jamshidi needle (the traditional manual) method of bone marrow sampling. This research study is designed to evaluate the effectiveness of the Jamshidi needle compared to the battery-powered bone marrow biopsy system.

100 participants will be enrolled in this study at Emory University.

Detailed Description

PRIMARY OBJECTIVE:

I. Assessing the quality and quantity of bone marrow core biopsies.

SECONDARY OBJECTIVES:

I. Assessing the nature of pain by established visual analogue scale (VAS) questionnaires.

II. Timing of the actual procedure.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients undergo bone marrow biopsy using the power drill.

ARM II: Patients undergo bone marrow biopsy using the traditional Jamshidi needle.

All patients complete questionnaires at baseline, 30 minutes after biopsy, and on days 1, 3, and 7.

After completion of study treatment, patients are followed up periodically.

Primary Outcome Measures
NameTimeMethod
Bone marrow core biopsy length (in mm) and artifacts assessed by the pathologistAt the time of biopsy

Bone marrow biopsy length is studied with mean, median, range, and standard deviation and compared by two-sample t-test.

Secondary Outcome Measures
NameTimeMethod
Time taken by the procedure measured in seconds using a stopwatchAt the time of biopsy

Staff members will use a stopwatch from the beginning to the completion of the procedure (skin to skin). Time taken for procedure is studied with mean, median, range, and standard deviation and compared by two-sample t-test.

Intensity of pain measured using visual analogue scale (VAS) pain questionnaireAt the time of, 30 minutes, 1, 3, and 7 days after biopsy

The VAS (visual analogue scale) for pain is on a 10 point scale. Pain is studied with chi-square, Mann Whitney U test, or Fisher's exact test.
