Abstract:
PURPOSE: Patient-reported questionnaires to assess taste changes (TC) among patients with cancer and the common domains or aspects assessed by those questionnaires are identified in this narrative review. Taste changes are a prevalent symptom experienced by patients with cancer that impact food choice and enjoyment, reduce food intake, and diminish quality of life. Appropriate assessment is essential to detect and manage this symptom.
METHOD: A systematic search of relevant databases between 1999 and 2018 yielded 1959 articles; 38 articles were included in the review.
RESULTS: Seventeen questionnaires designed specifically to assess patient-reported taste changes among patients with cancer are described in the review. Seven domains were identified among the questionnaires; the most frequently assessed domain was the description of the taste change in 14 questionnaires). Timeframe, scoring, number of items and domains, and item phrasing varied greatly among questionnaires and the approach to domain and item evaluation was inconsistent. Comprehensive questionnaires (n = 7) assessed five or more domains to characterize the taste change experience. The majority of questionnaires have been cited only once or twice.
CONCLUSION: Patient-reported taste change assessment in oncology has been achieved by a large number of diverse questionnaires; no standard tool or approach is used. Development of a question bank of validated or standardized taste change modules or items may strengthen the consistency and applicability of research in this area.
