Utility of the Skin Cancer Quality of Life Impact Tool

Background:

Patient-reported outcome measures (PROMs) provide validated evidence of health and quality of life (QoL) from the patient perspective. Several national PROMs programmes have been implemented in the National Health Service - specifically for common elective procedures. Local implementation is varied across settings and populations. The incidence of non-melanoma skin cancer (NMSC) is rapidly increasing, posing considerable burden on UK healthcare resources, yet there is limited evidence of use of PROMs in NMSC and little information about patients' perceived health and QoL.

Objectives:

This study will explore feasibility of implementing a skin cancer-specific PROM - Skin Cancer Quality of Life Impact Tool (SCQOLIT) for NMSC.

Methods:

Three hundred patients with a pathological diagnosis of NMSC undergoing all treatment modalities will be recruited to complete SCQOLIT questionnaires at baseline, at 3, 6 and 9 months. Participation and response rates, missing data and individual change scores will be analysed. Staff and patients will be interviewed to explore acceptability and feasibility of collecting PROMs data.

Results:

Interim results of the project to date will be presented. Feasibility will be assessed by evaluating number of eligible patients, number of consenting patients, reasons for not consenting and participant number. Individual longitudinal change in scores, response rates and psychometric properties of the SCQOLIT will be reported.

Implications:

Acceptability and feasibility of the SCQOLIT tool has never been rigorously assessed in Dermatology clinics. A validated NMSC-specific PROM would help standardize multi-centred trials, allow robust evaluation of quality of care and more appropriately direct healthcare resources to improve QoL in patients with NMSC.

Background:

Skin cancer is the most rapidly increasing cancer type in fair-skinned populations worldwide. Although non-melanoma skin cancer (NMSC) are rarely life threatening, both disease and treatments can be associated with substantial morbidity and confer significant financial burden to the National Health Service (NHS). Consequently, the British Association of Dermatologists (BAD) commissioned the Patient-reported Outcomes Measurement Group, Oxford to review the evidence for PROMs for skin cancer. The authors concluded that cancer-specific quality of life (QOL) questionnaires appeared more sensitive than generic PROMs e.g. the Dermatology Life Quality Index (DLQI), in capturing relevant QOL issues. In the NMSC population, these issues include scarring, disfigurement, anxiety and fear of future skin cancers.

One skin cancer-specific PROM that was evaluated was the Skin Cancer Quality of Life Impact Tool (SCQOLIT). The SCQOLIT is a ten-item instrument developed specifically for patients with non-metastatic skin cancer, which has demonstrated evidence in favour of reproducibility, validity, internal consistency but requires further evaluation.

The decision to evaluate the SCQOLIT in this study, includes its similarity in overall format and brevity to that of the DLQI which is a PROM now widely used in routine medical dermatology clinical practice. The SCQOLIT takes less than five minutes for the patient to complete and has a similar score calculation to the DLQI. Acceptability and feasibility of this tool has never been rigorously assessed in Dermatology clinics. Studies evaluating PROMs in NMSC have been largely assessed in relation to surgical treatments yet basal cell carcinoma can be effectively treated using medical treatments e.g. topical immunomodulators and photodynamic therapy, and to date, PROMs have not been investigated in these sub-populations.

Justification:

This feasibility study is designed to evaluate the SCQOLIT questionnaire, and aims to establish its utility and impact in patients with NMSC. The investigators will assess both patient and clinician acceptability of the SCQOLIT questionnaire tool and hope to identify any unmet needs, which can potentially inform future clinical decisions and/or service planning.

Study design:

Participants:

All patients referred to Dermatology Tumour outpatient clinics with a clinically suspected NMSC.

There will be four categories of participants, Groups 1 - 3 are participants with a new diagnosis of NMSC (primary or recurrent) on any site of the body:

Group 1 (Postal) - this will include those patients with a 'low risk' NMSC (namely basal cell carcinoma)

Group 2 (Clinic-based) - this will include those patients with a 'moderate to high risk' NMSC (namely SCC or other rare NMSC)

Group 3 (Interview) - these will be volunteers selected from Groups 1 and 2.

Group 4 (Focus Group: Clinicians) - this will include any Dermatology staff member who is involved in consenting and collecting PROMS data and has a role for direct care of patients attending Dermatology outpatient clinics.

Eligibility Criteria:
Inclusion Criteria:

* Adults aged over 18 yrs old
* All patients with a histopathological diagnosis of NMSC (primary or recurrent disease)
* All treatments used for NMSC will be included; excision, shave excision, curettage and cautery, Mohs micrographic surgery, photodynamic therapy and topical treatments e.g. imiquimod cream.

Exclusion Criteria:

The participant may not enter the study if ANY of the following apply:

* Concurrent internal malignancy as this is likely to significantly influence QOL.
* Patients referred onwards to other specialties for management of their skin cancer e.g. Plastic surgeons / Clinical oncology.
* Other significant dermatological diseases e.g. severe inflammatory or blistering skin conditions as this may influence QOL.
* Inability to consent for themselves.
