Core information set for informed consent to surgery for oral or oropharyngeal cancer: A mixed-methods study

To develop a core information set for informed consent to surgery for oral/oropharyngeal surgery. A core information set is baseline information rated important by patients and surgeons and is intended to improve patients' understanding of the intended procedure.

A mixed-methods study. Systematic reviews of scientific and written healthcare literature, qualitative interviews and observations, Delphi surveys, and group consensus meetings identified information domains of importance for consent.

A regional head and neck clinic in the United Kingdom. Questionnaire participants were recruited from around the UK.

Patients about to undergo, or who had previously undergone, surgery for oral/oropharyngeal cancer. Healthcare professionals involved in the management of head and neck cancer.

The main outcome was a core information set.

Systematic reviews, interviews and consultation observations yielded 887 pieces of information that were categorised into 87 information domains. Survey response rates were 67% (n = 50) and 71% (n = 52) for patient and healthcare professional groups in round one. More than 90% responded in each group in the second round. Healthcare professionals were more likely to rate information about short-term or peri-operative events as important while patients rated longer term issues about survival and quality of life. The consensus-building process resulted in an agreed core information set of 13 domains plus two procedure-specific domains about tracheostomy and free-flap surgery.

This study produced a core information set for surgeons and patients to discuss before surgery for oral/oropharyngeal cancer. Future work will optimise ways to integrate core information into routine consultations.
