Key factors influencing patient experience of total body photography (TBP) in skin cancer screening and diagnosis: a modified Delphi study
摘要
Total body photography (TBP) has been shown to support early detection of melanoma in high-risk populations and is likely to become part of routine clinical practice. However, TBP presents challenges related to privacy and confidentiality than other medical photography, thus requiring additional considerations to support a positive patient experience. Currently, there is a lack of good-practice guidelines or standardised tools to capture patient experience of TBP. This study aimed to identify key factors that influence patient experience of TBP in skin cancer screening and diagnosis and develop the baseline items for a proposed patient reported experience measure (PREM) tool. A two-round modified Delphi was conducted with a 20-member expert panel comprising 14 Nurse/Melanographers (70%), 4 Dermatologists (20%), and 2 Researchers (10%), involved in TBP capture. The panel rated and commented on 37 candidate statements. Predefined consensus thresholds and panel feedback guided statement refinement. Consensus was reached on 37 statements (29 candidate, 2 modified and 6 new statements). Strong agreement was observed for statements addressing communication and consent, staff interaction, comfort and environment, and barriers and drivers of TBP. Statements addressing patients’ background of TBP, procedure preparation, imaging outcomes perceptions were also identified as important, while statements related to post-imaging and image utility showed inconsistent agreement and were largely removed. Key factors influencing patient experience of TBP were identified, forming a foundation for developing a patient-reported experience measure tool to support best practice and improve patient outcomes.
