There is good evidence to support the use of topical PDT for superficial nonmelanoma skin cancer and dysplasia; however, there is little information available on the structure, process and outcomes of PDT in clinical practice. We undertook a national survey to determine how PDT was being undertaken in dermatology centres in Scotland. We highlight important information on the practicalities of PDT service delivery and the types of patients and diagnoses treated, and provide preliminary information on the outcomes achieved. These data will be invaluable as a starting point to agree on minimum standards for PDT and criteria to audit against these standards.
