Feasibility work to inform the design of a randomized clinical trial of wound dressings in elective and unplanned abdominal surgery.

摘要

Designing RCTs in surgery requires consideration of existing evidence, stakeholders' views and emerging interventions, to ensure that research questions are relevant to patients, surgeons and the health service. When there is uncertainty about RCT design, feasibility work is recommended. This study aimed to assess how feasibility work could inform the design of a future pilot study and RCT (Bluebelle, HTA - 12/200/04).
