Awareness and acceptability of Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials core outcome set for chronic pain among surveyed neuropathic pain authors.
Aim: We assessed the knowledge and adoption of Initiative on Methods, Measurement and Pain Assessment in Clinical Trials (IMMPACT)-recommended core outcome set (COS) and core outcome measures (COM) among authors of systematic reviews (SR) and randomized controlled trials (RCT) about interventions for neuropathic pain (NeuP).
Methods: NeuP SR and RCT authors identified via a systematic literature search were surveyed.
Results: The response rate was low. Although majority of respondents were familiar with the IMMPACT COS, only 61% of SR authors and 40% of RCT authors used the COS. The main perceived obstacle that prevented the adoption of the COS was the lack of awareness of the full IMMPACT COS.
Conclusion: The adoption of IMMPACT-recommended COS and COM among NeuP authors was inadequate and their appropriateness needs to be further evaluated.
