What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pain on VAS Score
Time Frame: one week after treatment
|
assess on visual analogue scale (VAS) score of 0 - 10cm, with 0 representing no pain experienced through to 10 representing the worst pain imaginable.
The participant marks across a 0-10cm unmarked line where their level of pain experience is and this is measured eg.
2cm if experiencing mild pain or 8.5cm which would represent severe pain

one week after treatment

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Phototoxicity
Time Frame: one week after treatment
|
erythema, oedema, blistering, crusting, ulceration on semi-quantitative scale. Erythema is graded as 0 = absent, 1 = mild, 2 = moderate or 3 = severe erythema as assessed by naked eye examination. Oedema is graded as 0 = absent or 1 = present. Likewise crusting or ulceration are each graded as 0 = absent and 1 = present by naked eye examination. Data will be presented and analysed separately ie. erythema data will be presented and then separately whether oedema, crusting or ulceration are present or absent. ie. reporting may appear as example: erythema score 3 of range of 0-3 options; oedema score 1 (binary option of 0 or 1); crusting score 0 (binary option of 0 or 1); ulceration score 0 (binary option of 0 or 1) |
one week after treatment
|
Clinical Clearance of Lesion
Time Frame: 12 months after treatment
|
clinical assessment by study dermatologist to determine by inspection and palpation whether the lesion is clear, partially clear or not clear - assessed at 3, 6 and 12 months after treatment, with 12 months as the final study outcome endpoint analysed
|
12 months after treatment
|
Patient Satisfaction
Time Frame: one year after treatment - last visit
|
brief patient questionnaire to evaluate their opinion of the treatment they received. This is assessed as A.efficacy of treatment - 1 = not effective NR; 2 = partIally effective PR; 3 = completely effective CR; B.Side effects of treatment eg. pain and inflammation - 1 = severe; 2 = moderate; 3 = mild; 4 = none/minimal. C.Practicalities of treatment eg. ease of use, travel, time, inconvenience - 1 = very disruptive and difficult; 2 = moderately disruptive and difficult; 3 = minimally disruptive and difficult. The scores of A, B and C will be added to give an overall score with range of overall minimum score option 3 and maximum 10. Patients will also separately be asked to give overall evaluation on a VAS scale of 0 = treatment very poor and would not have again through to 10 = treatment excellent and I would have again - with a continuous line option from 0 - 10 to mark across, providing a separate score with range options 0 to 10 |
