Patient-reported information on outcomes such as symptom-burden and health-related quality of life (QoL) is regarded as a useful tool to improve quality of care in clinical cancer research. However, integrating patient-reported information in the routine clinical practice is often difficult due to excessive time use and practical barriers. Electronic data acquisitions, where the treating physician has immediately access to the patient-reported data in the subsequent consultation, have been shown to be beneficial in the everyday clinical decision making.

The aim of this study is to develop and test a computer-based patient-reported assessment tool that will assist the clinicians in tracking long term and late effects in head and neck cancer patients and investigate if the tool leads to improved symptom assessment of a range of head and neck cancer specific symptoms, which again may lead to improved symptom control and enhanced quality of life in the patients.

Patients with a diagnosis of head and neck cancer attending the oncology outpatient clinics at Herlev Hospital and physicians and nurses who work at the clinic will be invited to participate. The assessment tool will be developed with inspiration from prior international studies of symptom assessment in head and neck cancer patients and tailored so that it will fit into a Danish context. The tool will be tested in a controlled intervention study. In the intervention group, patients will complete the assessment tool in the patients waiting area prior to every scheduled consultation. The result will then be printed and provided to the treating physician. In the control group, the patients will complete the assessment tool prior to consultations. However, the data will not be provided to the physicians at any time.

To assess the impact of the tool on number of symptoms addressed during consultations and patients' overall quality of life, medical records will be reviewed for before start of intervention and again at 6 and 12 months follow-up. The patients will also complete the EORTC QLQ-C30 and the EORTC QLQ-H&N35 at baseline and at 6 and 12 months follow-up. Furthermore, we will conduct a qualitative evaluation (semi structured interview and participant observations) of attitudes among clinicians and patients regarding the use of tool at the point of care.

• Prevalent recurrence free patients with cancers in the tongue, oral cavity, pharynx and larynx attending the oncology clinic at Herlev Hospital, Herlev, Denmark. 9 months to 5 years after end of treatment

Exclusion Criteria:

• Patients with recurrence of their cancers and patients still in treatment.
