Hubiche T, Valério L, Boralevi F, et al. Visualization of Patients’ Skin Lesions on Their Smartphones: A New Step During Dermatology Visits. JAMA Dermatol. 2016;152(1):95–97. doi:10.1001/jamadermatol.2015.2977
Smartphones are a new potential source of medical data.1,2 During dermatology appointments, we have observed an increasing number of patients presenting a picture of their skin lesions during the visit. The utility of the information provided by pictures on smartphones has not been evaluated. To assess their utility, we determined the proportion of patients whose smartphone photographs provided information relevant to their diagnosis.
We conducted a cross-sectional study from March 14 to May 31, 2014, in 21 departments of pediatric and general dermatology. The final follow-up occurred on June 4, 2014. We included all outpatients presenting a picture of their skin lesion during the visit. Data on the patients’ characteristics, the quality of the photographs, the diagnosis, and the information provided by the photograph were collected through a standardized survey completed by the senior treating dermatologists (Figure); identification of the patients was not possible in accord with the French rules of ethics. The main outcome variable was the value of the information gained by viewing the picture as assessed by the study dermatologists: namely, whether the information strengthened, modified, or confirmed the diagnosis. Data analysis was performed from June 4 to June 14, 2014. We used the χ2 test, the Fisher exact test, or the t test as appropriate. All tests were 2 sided with a level of significance of .05. The institutional and ethical review board of Nice University stated that approval was not required for this study; oral consent was obtained from all patients after they received oral information about the study. We used SPSS software (version 16.0; SPSS Inc) for the statistical analysis.
We included 162 patients (male to female ratio, 0.4), of whom 109 (67.3%) were younger than 10 years. Sixty different diagnoses were recorded, with the most frequent being urticaria (22 patients [13.6%]), eczema (11 patients [6.8%]), psoriasis (11 patients [6.8%]), viral exanthema (10 patients [6.2%]), atopic dermatitis (9 patients [5.6%]), and infantile hemangioma (8 patients [4.9%]). One hundred fifty-three patients (94.4%) reported obtaining the photograph for medical reasons. The median period from the date of the photograph to the visit was 20.0 days (interquartile range, 7.0-52.0 days). The quality of the photograph was considered good in 74 patients (45.7%), average in 70 (43.2%), and poor in 18 (11.1%). When compared with the photograph, skin lesions had changed by the time of the visit in 141 patients (87.0%). Physicians considered that the photographs provided additional information for 124 patients (76.5%). This information strengthened the diagnosis in 83 patients (66.9%), modified it in 19 (15.3%), and confirmed it in 22 (17.7%). Treatment was changed in 44 of these 124 patients (35.5%) because of the information provided by the photographs.
In 48 patients without a skin lesion at the time of the visit (29.6%), the photographs strengthened the diagnosis in 21 patients (43.8%), modified it in 10 (20.8%), and confirmed it in 12 (25.0%), respectively. The absence of a skin lesion at the visit was the only factor associated with a significant reported gain of information (P = .01; Table). Among the 114 patients with skin lesions at the visit, the main information provided by the photographs consisted of evolution of the skin lesions in 25 patients (21.9%), visualization of a complication or a flare-up of a chronic disease in 18 (15.8%), and the initial appearance of the skin lesion in 30 (26.3%).
This study shows that photographs obtained by patients on their smartphones are a new source of data for dermatologic diagnosis. Patients’ photographs provide information on the evolution of skin lesions, the onset of a flare-up or a complication of a chronic skin disease, and the initial aspect of the skin disease, which was especially important in the one-third of patients who came to the visit without a skin lesion. Recently, the relevance of patients’ pictures was demonstrated in infantile hemangioma growth during the first weeks of life.3
No differences in the dermatologic condition recorded in patients’ photographs were observed. The lack of statistical difference could be owing to the small number of patients for each disease group. However, this lack of significance suggests that the information provided by photographs may be useful for most skin diseases.
Patients seem to have adopted this new tool easily for health purposes. Patients’ smartphone photographs provided relevant information for the diagnosis and treatment decision, which usually is based only on the medical history reported by patients. Because the photographs influence diagnosis and treatment, the photographs should be saved in the patients’ medical records. With such digital tools, patients can assist physicians and become more involved in their health care.
