A multinational survey characterizing the use of surgical magnifying loupes in dermatological surgery.

Abstract

The use of surgical loupes has not been well-documented in dermatological surgery. An online questionnaire was developed to characterize the use of loupes in dermatological surgery. The questionnaire was circulated to the memberships of the British Society of Dermatological Surgery, the European Society of Micrographic Surgery, and the Australasian College of Dermatologists. Responses were analyzed with a mixed methods approach using quantitative data analysis and inductive content analysis. One-hundred twenty-five valid responses were received from 20 nations. Most respondents were from England (40%; 50/125), Australia (16%; 20/125), and the Netherlands (14.4%; 18/125). Overall, 71.2% (89/125) of respondents were consultants/Facharzt/attending. Furthermore, 55.2% (69/125) of respondents were Mohs surgeons. In dermatological surgery 38.4% (48/125) of respondents used surgical loupes routinely. The mode magnification level for loupes was 2.5× (67.5%; 27/40), with 3× second place (12.5%; 5/40). Exactly half (20/40) used through-the-lens style loupes and 40% (16/40) used flip-up-loupes. Inductive content analysis of the 51 free-text responses from nonloupe users uncovered several deterring factor themes, including expense (18/51), can manage without/don't need (14/51), and narrow field of view a(11/51), and uncomfortable/too heavy (9/51). This is the first time the use of surgical loupes in dermatological surgery has been internationally characterized.
