World Workshop on Oral Medicine VIII: Development of a core outcome set for dry mouth: the patient perspective.

OBJECTIVE

We conducted a qualitative study of patients' perspectives on dry mouth outcomes to explore their personal experiences and investigate which outcomes are most important to them. This work was part of the WONDER initiative (World Workshop on Oral Medicine Outcomes Initiative for the Direction of Research) exploring Core Outcome Measures in Effectiveness Trials.

STUDY

DESIGN

Using a study-specific topic guide, we conducted digitally recorded, semi-structured interviews of focus groups of patients with dry mouth secondary to Sjögren syndrome and head and neck radiotherapy. We conducted interviews until data saturation had been achieved and evaluated all transcripts for accuracy before we anonymized the data.

RESULTS

Two focus groups consisting of 4 participants per group identified 4 distinct themes: (1) impact on oral health and function, (2) social isolation and withdrawal, (3) frustration with dry mouth management, and (4) limited knowledge of the medical community and lack of understanding of family and friends.

CONCLUSIONS

The diversity of self-reported outcomes and the complexity of patient perceptions identified in our work may represent additional barriers to successful dry mouth management that should be considered in the design of future clinical trials.
