Actinic Keratoses, Basal Cell Carcinoma, Squamous Cell Carcinoma
Conditions
Brief summary
Rationale: Keratinocyte skin cancer is known to influence the HRQoL in a specific way. Derived utility values are required for cost-effectiveness analyses of new interventions. However there is no sensitive tool to capture HRQoL that translates into utilities available. Objective: To document the exact HRQoL in patients with in KC using the generic EQ-5D-5L questionnaire, as well as the TTO, 15D and the BaSQoL questionnaire, and to develop health utilities based on these tools. Study design: Longitudinal observational study (at time 0 and time 0 +12 months). Study population: Patients aged ≥18 years consulting a dermatologist or their GP for diagnosis, treatment or follow-up of a (pre)malignant skin lesion(s).

Interventions
OTHERquestionnaires
EQ-5D-5L questionnaire questioning their overall health on five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). In addition patients will have to fill in the generic 15D questioning 15 specific dimensions on 5 levels as well as the BaSQoL, which is a disease specific questionnaire for patients with KC. The Time-trade off task is the final question.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Health utility (by using a time trade off questionnaire) | 1 year | Utilities as determined by the time trade off, this is a technique used to measure the quality of life that a person or group is experiencing. An individual will be presented with a set of directions such as, and the result will be a health utility index between 0-1. Lower scores mean less HrQoL. |
| Health utility (by using the 15D questionnaire) | 1 year | Utilities as determined by the 15D questionnaire, a generic questionnaire developed to determine a health utility index between 0-1. Lower scores mean less HrQoL. |
| Health utility (by using the EQ-5D-5L questionnaire) | 1 year | Utilities as determined by the EQ-5D questionnaire, a generic questionnaire developed to determine a health utility index between 0-1. Lower scores mean less HrQoL. |
