Ylva Maria Gjelsvik

Ylva Maria Gjelsvik, special adviser in the Department of Registry and responsible for patient-reported data. She is responsible for developing, organising and quality assuring population surveys on health and quality of life in the Cancer Registry.

The population surveys measure the health and quality of life of people with cancer both at diagnosis and over time using a questionnaire. People who do not have cancer are invited as a control group. The purpose of the population surveys is to obtain knowledge that can help reduce late effects and improve health-related quality of life for people with cancer.

Results and findings from the population surveys are published in the annual reports from the Cancer Registry's quality registries and as articles in journals. Gjelsvik is also a project participant in three research projects that use patient-reported data.
