Store-and-forward teledermatology results in similar clinical outcomes to conventional clinic-based care.
ABSTRACT We compared the clinical outcomes after store-and-forward teledermatology with those following conventional clinic-based consultation. Subjects were randomized to either usual care (a conventional clinic-based dermatology appointment) or a store-and-forward teledermatology consultation. All subjects received baseline digital imaging and re-imaging was performed four months later. A total of 776 subjects were approached for inclusion, and a total of 508 image sets were reviewed, 236 in usual care and 272 in teledermatology. The image sets from both study arms were used to make clinical outcome assessments between baseline and four months. A dermatologist who was blinded to the randomization rated the clinical outcomes using a three-point clinical course rating scale (1 = improved, 2 = no change, 3 = worse). In the usual care group, 65% were rated as 'improved', 32% were rated as 'no change' and 3% were rated as 'worse'. For teledermatology, 64% were rated as 'improved', 33% as 'no change' and 4% as 'worse'. The results of the study indicate that store-and-forward teledermatology consultations produce similar clinical outcomes when compared with conventional clinic-based consultations.

ABSTRACT: Previous research suggests that technology-enabled health care delivery may improve access to dermatologic specialty care. Outcomes research using validated outcomes measures is necessary for evaluation of novel health care delivery models. We sought to compare the clinical equivalence of a novel patient-centered online health care delivery model with standard in-office care for follow-up treatment of patients with psoriasis. A total of 64 participants with psoriasis were randomized to receive follow-up care either in-office or online over a 24-week period. Patients randomized to the online group underwent standardized training on capturing high-quality digital images of their psoriatic skin and transmitting these images and clinical history to a dermatologist securely. The dermatologist then performed asynchronous, online evaluation and provided recommendations directly to patients. We used clinically validated disease severity and quality-of-life measures to assess effectiveness between the models. Both online and in-office groups showed improvement in psoriasis disease severity as measured by mean improvement in Psoriasis Area and Severity Index (online group: mean = -3.4, in-office: mean = -3.4). Patient-centered online care resulted in similar improvement in psoriasis severity compared with in-person follow-up care (mean difference in Psoriasis Area and Severity Index change 0.1, 95% confidence interval -2.2 to 2.3, a priori equivalence margin of 2.5). Investigator Global Assessment and Dermatology Life Quality Index scores also improved during the study period; no significant differences existed between the two groups. The follow-up period was limited to 24 weeks. A patient-centered online model may be an effective alternative to in-office care for follow-up management of psoriasis.Journal of the American Academy of Dermatology 09/2011; 66(6):948-53. · 4.91 Impact Factor

ABSTRACT: Abstract Objective: To determine whether teledermatology referrals yield a shorter time to biopsy of the most common types of skin cancer versus conventional dermatology referrals. Subjects and Methods: A retrospective chart review was performed of California's Central Valley Kaiser Permanente conventional dermatology or teledermatology referrals that yielded a positive skin cancer biopsy over a 7-month period. Four primary care clinics at Kaiser Permanente's Stockton Medical Center in California's Central Valley were included. Patients who were studied were treated for squamous cell carcinoma of skin, basal cell carcinoma of skin, and malignant melanoma. We compared the time interval between initial evaluation and biopsy of the most common types of skin cancer for teledermatology versus traditional referrals from primary care. Results: Our study criteria were met by 293 patient cases (58% conventional referrals and 42% teledermatology referrals). The mean time to biopsy of skin cancer was 13.8 days for conventional referrals (median, 12.0 days) versus a mean of 9.7 days (median, 9.0 days) for teledermatology referrals (p<0.0001). Conclusions: The use of teledermatology in remote areas results in a shorter time to biopsy than traditional referral methods as a result of improved triaging measures.Telemedicine and e-Health 10/2013; 19(10):780-785. · 1.40 Impact Factor
