The effectiveness of non-pharmacological interventions on reducing pain in patients undergoing bone marrow aspiration and biopsy: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND

Patients often consider bone marrow aspiration and biopsy to be one of the most painful medical procedures. The effectiveness of non-pharmacological interventions to reduce pain during bone marrow aspiration and biopsy remains unclear.

AIM: To synthesize existing evidence regarding the effectiveness of non-pharmacological interventions in mitigating procedural pain among patients undergoing bone marrow aspiration and biopsy.

DESIGN

A systematic review and meta-analysis of randomized controlled trials.

METHODS

Six electronic databases, including PubMed, EMBASE, CINAHL, PsycINFO, Cochrane Library and Web of Science were searched from inception to July 15, 2023. The risk of bias was assessed using the Cochrane Risk of Bias Tool Version 2.0. Meta-analysis was conducted using STATA 16. The certainty of the evidence was assessed by the GRADE approach.

RESULTS

This meta-analysis included 18 studies derived from 17 articles involving a total of 1017 participants. The pooled results revealed statistically significant pain reduction effects using distraction (SMD: -.845, 95% CI: -1.344 to -.346, p < .001), powered bone marrow biopsy system (SMD: -.266, 95% CI: -.529 to -.003, p = .048), and acupoint stimulation (SMD: -1.016, 95% CI: -1.995 to -.037, p = .042) among patients undergoing bone marrow aspiration and biopsy. However, the pooled results on hypnosis (SMD: -1.228, 95% CI: -4.091 to 1.515, p = .368) showed no significant impact on pain reduction. Additionally, the pooled results for distraction did not demonstrate a significant effect on operative anxiety (MD: -2.942, 95% CI: -7.650 to 1.767, p = .221).

CONCLUSIONS

Distraction, powered bone marrow biopsy system and acupoint stimulation are effective in reducing pain among patients undergoing bone marrow aspiration and biopsy.

PATIENT OR PUBLIC CONTRIBUTION: Not applicable.

RELEVANCE TO CLINICAL PRACTICE: This meta-analysis highlights the effectiveness of distraction, powered bone marrow biopsy system and acupoint stimulation for reducing pain in patients undergoing bone marrow biopsy. Healthcare professionals should consider integrating these interventions into pain management practices for these patients.
