Unmet information needs and clinical characteristics in patients with precancerous oral lesions

The purpose of this study was to investigate associated factors of the unmet information needs of patients with precancerous oral lesions. For this cross-sectional descriptive study, we recruited patients with precancerous oral lesions from the otolaryngology outpatient department of a single medical centre in central Taiwan. Patients were assessed using a set of structure questionnaires to measure patients' state anxiety levels, attitudes towards cancer prevention and need for information. Patients' anxiety and attitudes towards cancer prevention were evaluated based on unmet needs and associated factors were determined. Among the 106 subjects surveyed, the most prominent unmet information needs were about obtaining the test results as soon as possible. Patients with precancerous oral lesions who had high levels of state anxiety, long duration of time since quitting betel nut chewing and were without a history of oral cancer were more likely to have unmet information needs. A high level of anxiety about precancerous oral lesions was more prevalent among patients with unmet information needs than among those whose information needs were met. Health education and individual counselling should be provided to satisfy the information needs of this population.
