Diagnostic patterns and delays in autoimmune blistering diseases of the mouth; a cross-sectional study

Abstract

Objectives

To describe the natural history and factors influencing diagnostic delays among patients with autoimmune blistering diseases of the mouth.

Materials and methods

In this cross-sectional study, 27 newly diagnosed patients were interviewed, and professional and patient delays were calculated. Disease extent and severity scores were determined using Saraswat scoring system.

Results

Twenty-seven patients were interviewed and examined. Patient delay was significantly longer in patients who had desquamative gingivitis as initial presentation, in those who tried to use home remedies and over the counter medications, and in patients with less severe disease. Most patients (n= 21 [77.7%]) made more than one consultation, and the mean time needed to reach a definitive diagnosis (i.e. professional delay) was 83.2 ± 21.4 days (range from 21 to 130 days). Professional delay was significantly correlated with the number of previous consultations (r=0.78), and was significantly longer in patients who had desquamative gingivitis as initial presentation.

Conclusion

Diagnosis of oral blistering diseases is often delayed. Diagnostic delay is more common in patients presenting with desquamative gingivitis and those with less severe disease. Improving patients and health care professionals' awareness about oral blistering diseases might help reduce diagnostic delay.
