Clinical Accuracy Of Dermatologists And Nondermatologists In The Diagnosis Of Dermatological Diseases

To compare the clinical diagnostic accuracy of dermatologists and non- dermatologists in the diagnosis of dermatological diseases.

The descriptive, cross-sectional study was conducted at the Dermatopathology department of a tertiary healthcare hospital in the Punjab province of Pakistan from January 1 to December 31, 2019, and comprised biopsy specimens of patients with diseases of the skin and subcutaneous tissue. The clinical diagnoses of general surgeons, otolaryngologists, dental/maxillofacial surgeons, plastic surgeons and gynaecologists were noted and compared with those of dermatologists in the light of histopathological findings. Data was analysed using SPSS 16.

Of the 386 specimens submitted, 113(29.3%) were sent by dermatologists and 273(70.7%) by non-dermatologists. Clinical diagnostic accuracy of dermatologists 92(81.4%) compared to non-dermatologists 137(50.2%) (p<0.005). The dermatologists diagnosed significantly more cases belonging to inflammatory and miscellaneous cutaneous diseases category accurately than non-dermatologists (p<0.005). Similarly, the dermatologists diagnosed significantly more cases of neoplastic disorders accurately than the non-dermatologists (p= 0.018). There was no significant difference in the clinical diagnostic accuracy of dermatologists and non-dermatologists in cases of cystic lesions (p>0.05). In the neoplastic category, no significant difference was found in the clinical accuracy of dermatologists and plastic surgeons (p=0.347).

The specialised skills of dermatologists could not be matched by any other group of physicians.
