An audit of the value of patch testing and its effect on quality of life.
We have assessed the value of patch testing from the patient's perspective and examined the impact of patch testing on their quality of life (QoL). 140 patients were recruited over 5 months. 2 questionnaires were designed to investigate the patient's views on patch testing. The 1st questionnaire was completed at the final visit to the clinic and the 2nd was posted 6 weeks later. The Dermatology Life Quality Index (DLQI) questionnaire was completed on both occasions. There was a significant improvement of the DLQI score in all patch-tested subjects (P = 0.003). Patients with involvement of the trunk had worse QoL. At the 4-day visit, 77 patients (55%) expressed the opinion that patch testing had been helpful. 6 weeks later, 71 patients replied. 47 patients were diagnosed as having allergic contact dermatitis: 87% of them found that patch testing had been useful, 91% were able to avoid the allergen(s) and 57% reported improvement/clearing in their skin condition. 58% of the 24 patients with negative results also found that patch testing had been beneficial. Overall, patient perception was that they understood verbal information (92%) better than written information (76%). Patch testing is beneficial to patients, leading to improved QoL. Patient perception was that they understood verbal advice better than written information.
