Survey of patch testing in Scotland

We have surveyed Scottish dermatologists to establish the extent of patch testing, to assess the reasons for referral and to document resources and methods used by dermatologists. 104 questionnaires were sent to members of the Scottish Dermatological Society. 82 questionnaires (79%) were returned. 50% of respondents were consultants, 27% were trainees and 23% held staff grade or clinical assistant positions. The mean waiting time for a patch test appointment was 4.5 months. The most frequent reasons for patch testing were localized eczema, eczema not responding to conventional treatment, occupational eczema, history of contact sensitivity and eczema of uncertain cause. 17 of 82 respondents (21%) were the principal clinicians supervising patch testing in their hospitals. 11 of 17 read reactions at 2 and 4 days. Mean time spent on advising patients was 13 min per patients. 7 of 17 were dissatisfied with resources available for patient education and 16 of 17 felt they would benefit from a central source for patient information. Only 4 of 17 centres recorded patch test results on a database and 3 centres regularly reviewed their patch test results. In conclusion, we have identified areas of patch testing that require further improvement.
