  • Il presente studio ha valutato le prestazioni di teledermatologia per i casi di psoriasi sospetta o già diagnosticata nel periodo 2016-2020 nello stato di Santa Catarina in Brasile.
  • Le diagnosi di psoriasi effettuate con la teledermatologia, rispetto alle altre dermatosi, tendono a essere connesse ad un trattamento in un centro di primo (p <0.001) o terzo (p <0,001) livello, con una riduzione degli invii a quelli di secondo livello.



Psoriasis is a skin disease that affects 1.3% of Brazilians. The use of teledermatology (TD) in the public health sector has democratized access to dermatological care.


To analyze TD exams with suspected and/or diagnosed psoriasis performed between 2016-2020 in the state of Santa Catarina (SC).


Analytical cross-sectional observational study that used secondary data collected from the records of TD exams from the Telemedicine and Telehealth System (TTS) of SC. The associations were evaluated by the chi-square test and Student’st test. The significance level was set at 5% (p <0.05).


During the period, 6,146 TD exams were related to psoriasis, 58% due to the diagnosis provided by the reporting dermatologist and 42% exclusively due to the suspected disease on the request of the examination. The male sex predominated among the diagnoses of dermatosis (51%; p <0.001). Regarding risk classification, psoriasis diagnoses were predominantly yellow (58.7%; p <0.001) or blue (39.7%; p <0.001) risk, respectively indicating moderate to severe psoriasis (referral to tertiary care) and mild psoriasis (treatment in the primary health care [PHC] level). True positive tests, suspected by PHC and diagnosed with psoriasis through TD, were 34.1% (p <0.001).

Study limitations

The TD service is available only for the public health network and analysis for a limited period (five years).

Conclusions and perspectives

Psoriasis diagnoses performed by TD, when compared to other dermatoses, tend to receive treatment at the primary (p <0.001) or tertiary (p <0.001) health care level, reducing the number of referrals to the secondary care level.
