摘要

Background

Patch testing (PT) is the diagnostic gold standard for allergic contact dermatitis (ACD), but data on patient outcomes and experiences after having time to implement test results are limited. Further, prior studies often rely on general dermatologic measures and lack long-term follow-up.

Objective

To evaluate patient-reported outcomes, behavioral changes, and satisfaction six months after PT using both ACD-specific and general dermatologic quality-of-life tools.

Methods

Patients who underwent PT and completed pre- and post-test surveys at a single academic center between September 2022 and 2023 were recontacted to complete six-month follow-up surveys. Instruments included the Dermatology Life Quality Index (DLQI), the ACD-11, and questions on behavioral change, satisfaction, and use of the Contact Allergen Management Program (CAMP) app. Responses were analyzed and compared to baseline.

Results

Of 111 initial participants, 51 (46%) completed follow-up, including 27 who tested positive and 24 who tested negative. ACD-11 scores improved significantly in the allergen-positive group (p = 0.006), with non-significant numerical improvements also seen in DLQI and in both scores in the no-allergen group. Both groups reported behavioral changes, and 96% of respondents agreed that PT was beneficial. Although only 19% of positive testers used the CAMP app, nearly half found it easy to use and helpful.

Conclusions

PT was associated with sustained satisfaction and behavior change regardless of test result. ACD-11 was sensitive to clinical improvement, supporting its utility in ACD-specific populations. Personalized tools like CAMP may aid long-term implementation of PT results.
