Abstract

Objective: To understand participants’ experiences and understandings of the interventions in the trial of a computerised decision support tool in patients with atrial fibrillation being considered for anti-coagulation treatment.

Design: Qualitative process evaluation carried out alongside the trial: non-participant observation and semistructured interviews.

Participants: 30 participants aged >60 years taking part in the trial of a computerised decision support tool.

Results: Qualitative evidence provided the rationale to undertake a decision to discontinue one arm of the trial on the basis that the intervention in that arm, a standard gamble values elicitation exercise was causing confusion and was unlikely to produce valid data on participant values.

Conclusions: Qualitative methods used alongside a trial allow an understanding of the process and progress of a trial, and provide evidence to intervene in the trial if necessary, including evidence for the rationale to discontinue an intervention arm of the trial.
