The study compares a tri-partite scoring system (TPSS) used in teledermatology with the International Contact Dermatitis Research Group (ICDRG) grading, which is the standard for interpreting patch test results.
The TPSS showed high sensitivity and specificity, with excellent agreement between two investigators' scoring methods, indicating it is a reliable alternative.
The findings suggest that TPSS can effectively reduce patient visits by 50%, making it a practical option especially during situations like the COVID-19 pandemic.
