What are the views of those participating in a trial investigating acute post-traumatic benign paroxysmal positional vertigo? A qualitative study

Objective: The purpose of this study was to explore the experiences of patients and healthcare professionals participating in a randomized feasibility trial exploring the management of acute post-traumatic benign paroxysmal positional vertigo (BPPV), and to establish the acceptability and tolerability of BPPV assessment and treatment procedures. Methods: This was a multi-center qualitative study nested within a wider randomized feasibility trial. Purposive sampling was used to gather a cohort of healthcare professionals and patients from three major trauma centres in London, UK. Data were gathered using semi-structured interviews and were analyzed using Framework analysis. Results: Fifteen healthcare professionals and 26 patients participated. Patients and healthcare professionals reported acute BPPV diagnosis was acceptable and practicable. However, divergence was noted regarding views of randomization. Participants proposed several research delivery and protocol modifications for a future trial, including changes to study design and outcome measures. Conclusions: Healthcare professionals and patients participating in a multi-center qualitative study felt post-traumatic BPPV was feasible and acceptable to diagnose and treat acutely. Findings from this study will enhance the content and delivery of a future trial and may assist in influencing the development of clinical practice guidelines.
