A Multivariate Analysis of Pain and Distress in Adults Undergoing BMAB.

Clinicians routinely perform bone marrow aspiration and biopsy (BMAB) to diagnose cancer and evaluate disease status; however, few studies address pain and distress with BMAB. A prospective descriptive-correlational design examined patients' ( = 152) ratings of pain intensity (numeric rating scale, 0-10) and distress (distress thermometer) at baseline and 5 min and 1 hr postprocedure. Data were analyzed using descriptive statistics, chi-square, and linear regression models. Mean postprocedure pain intensity at 5 min was moderate, 5.56 ( = 3.03), and opioid use was associated with decreased pain at 1 hr ( < .001). Preprocedure administration of anxiolytics had no significant effect on distress reduction ( = .88). Being female, first-time biopsy, and increased preprocedure pain were significant predictors of postprocedure distress ( < .001). Treating anxiety alone may not be sufficient to lessen pain and distress. Individualized plans of care should be based on patient risk and response to procedure.
