Dear Editor,
The internet is a powerful and accessible media, it can also offer knowledge in the health area so that users may understand the possible involvement by a disease and its outcomes.11 Atkinson NL, Saperstein SL, Pleis J. Using the internet for health-related activities: findings from a national probability sample. J Med Internet Res. 2009;11:e4. Previous studies have shown that women, young people, university students, and individuals with higher incomes are more likely to seek health information on the internet.22 Ybarra M, Suman M. Reasons, assessments and actions taken: sex and age differences in uses of Internet health information. Health Educ Res. 2008;23:512–21. However, there have been few studies on the influence of research on dermatological diseases. Thus, given the Brazilian profile of intensive use of the internet, including for health information, it is necessary to study the way people use this tool in their daily lives.11 Atkinson NL, Saperstein SL, Pleis J. Using the internet for health-related activities: findings from a national probability sample. J Med Internet Res. 2009;11:e4., 33 Moretti FA, Oliveira VE, Silva EMK.

Considering the abovementioned facts, this study aimed to evaluate the prevalence of internet access to obtain information on skin health among dermatological patients, their demographic and search profile, and their associations with internet use, as well as the interactions of the results with dermatological care.
This is a cross-sectional, descriptive and exploratory study, carried out with patients from a public hospital in the hinterland the state of São Paulo, interviewed between July and September 2019. Participants were recruited for convenience in the waiting areas for scheduled outpatient dermatological care.
Patients over 18 years of age who were literate and had no communication problems, cognitive impairment, or psychiatric illness, that prevented the interview from being conducted, were included.
Data collection was carried out using a two-part investigation protocol: the first on patient demographics and the second on the use of the internet in health-related searches.
The study was approved by the institutional Ethics Committee (Counsel n. 3,661,913).
Continuous variables were analyzed as bivariate data using the parametric Student’s t test after normal distributions were assessed using the Shapiro-Wilk test. Categorical variables were compared using the chi-square or Fisher’s exact tests according to the lowest number of events in each analysis.
The variables indicating the type of researched information and the type of tool used in the search were analyzed using hierarchical clustering, linkages between groups, and Euclidean distance, represented by dendrograms using centroid linkage.
The minimum sample size consisted of 130 individuals for an exploratory analysis with up to 12 variables.
The categorical data were represented as absolute numbers and/or percentages, and non-categorical data as means and standard deviations.
The association between searching for skin-related health information on the internet and the other demographic variables was evaluated in a bivariate manner, and, subsequently, the significant variables were included in a multivariate logistic regression model.
Two-tailed values of p≤0.05 were considered significant.
Table 1 describes the socioeconomic data and the internet use of the 148 patients who agreed to participate in the research protocol.
Demographic and socioeconomic data of dermatological patients participating in the survey on the use of the internet to obtain information on skin health.
Table 2 depicts the association of demographic variables with having obtained dermatological health information from the internet. Obtaining this information was associated with young individuals, women, higher education, and having access to the internet at home. However, in multivariate analysis by logistic regression, including variables with p≤0.05, only age remained significant (p<0.01).
Demographic characteristics and association with obtaining skin health information in the internet.
The reliability of the information was not associated with age, sex, education, or income; discussing the results with the physician was directly correlated with schooling (p = 0.01 – chi-square trend) and income (p = 0.05 – chi-square trend); eliciting conflict with the medical conduct was not associated with sex, age, schooling or income; the search for alternative treatments was associated with young individuals (36.82 [12.32] 43.33 [14.17] years; p = 0.02 – Student’s t test) and a higher level of schooling (p < 0.01 – chi-square trend); and the performance of treatments based on virtual searches was associated only with young individuals (35.85 [13.21] × 42.80 [13.72] years; p = 0.02 – Student’s t test).
The cluster analysis of information types showed two main independent search patterns, focusing on the diagnosis, treatments, and other information. The analysis of the search portal and tools showed a predominant pattern of search engine use (Figs. 1 and 2).
It was observed that most of the participants use the internet to carry out health-related searches, corroborating the study hypothesis. A similar article published by the University of Pittsburgh (2015) showed that most participants (74.7%) used the internet to obtain health-related information. However, only a minority used it for dermatological purposes (38.7%).44 Wolf JA, Moreau JF, Patton TJ, Winger DG, Ferris LK. Prevalence and impact of health-related internet and smartphone use among dermatology patients. Cutis. 2015;95:323–8.
The present study shows that the search for information took place mainly on smartphones, which may be associated with convenience and easier access.
Although most interviewees use the internet for health-related searches, the obtained information does not have a great deal of influence on most of them. A study conducted in 2015 by the University of Granada described the stability of the bond between doctor and patient, even with the use of virtual tools.55 Orgaz-Molina J, Cotugno M, Girón-Prieto MS, Arrabal-Polo MA, Ruiz-Carrascosa JC, Buendía-Eisman A, et al. A study of Internet searches for medical information in dermatology patients: The patient-physician relationship. Actas Dermosifiliogr. 2015;106:493–9.
However, it is important to state that approximately 19% of the participants have already undergone some treatment based on virtual searches only, and 2.7% have already abandoned a treatment due to the internet.
As for the reason for the search, the main one was a diagnosis, followed by treatment options, which were sought mainly before the medical appointment. However, 45% of the interviewees sought information even after the appointment, suggesting the persistence of doubts or dissatisfaction with the medical approach.
Although age, sex, schooling, and home access to the internet were associated with the search for information on dermatological health in the bivariate analysis, it should be noted that in the multivariate analysis, only age remained significantly associated with the search for information on skin health. Thus, it is likely that technological, socioeconomic, and cultural factors associated with younger individuals lead them to seek more information about dermatological health on the internet.
It is emphasized that this study was carried out in a center including patients exclusively from the public health system, which may interfere with the validity of the results for the private health system or other regions in the country. However, the results were consistent with other studies on the same topic.
Therefore, it is concluded that the search for information about dermatological health on the internet is frequent, especially among young individuals, albeit with low reliability being attributed to the information. Hence, it is essential to adopt educational measures with the population on where to find reliable information.
