Changing paradigms in dermatology: information technology

Improved patient access and outcomes with the integration of an eConsult program (teledermatology) within a large academic medical center

BACKGROUND

Insurance, racial, and socioeconomic health disparities continue to pose significant challenges for access to dermatologic care. Studies applying teledermatology to increase access to underinsured individuals and ethnic minorities are limited.

OBJECTIVE

To determine how the implementation of a teledermatology program affects access to health care and patient outcomes.

METHODS

A cross-sectional evaluation was performed of all ambulatory dermatology referrals and electronic dermatology consultations (eConsults) at Ohio State University within a 25-month period.

RESULTS

Compared with ambulatory referrals, eConsults served more nonwhite patients (612 of 1698 [36.0%] vs 4040 of 16,073 [25.1%]; P < .001) and more Medicaid enrollees (459 of 1698 patients [27.0%] vs 3266 of 16,073 [20.3%]; P < .001). In addition, ambulatory referral patients were significantly less likely to attend their scheduled appointment compared with eConsult patients, as either "no-shows" (246 of 2526 [9.7%] vs 3 of 62 [4.8%]) or cancellations (742 of 2526 [29.4%] vs 8 of 62 [12.9%]; P = .003). There were fewer median days to extirpation for eConsult patients compared with ambulatory referral patients (interquartile range; 80.7 ± 79.8 vs 116.9 ± 86.6 days; P = .004).

CONCLUSION

Integrating dermatologic care through a telemedicine system can result in improved access for underserved patients through improved efficiency outcomes.

[Preliminary results of DERMATEL: prospective randomized study comparing synchronous and asynchronous modalities of teledermatology]

INTRODUCTION

There is considerable variability in the results of studies that evaluate diagnostic reliability in teledermatology. There are only two studies that compare the synchronous and asynchronous modalities of teleconsult in the same sample. We present the results of the pilot project DERMATEL, a study of diagnostic concordance that aims to increase the evidence of these aspects.

MATERIAL AND METHODS

One-hundred-fifty.nine patients referred by the general practitioner in the first consult were randomized (algorithm 3:2:1) in three arms: asyncronous teledermatology (store-and-forward or SAF), synchronous teldermatology (real-time or VTC), and conventional consult (CC). We used high-quality, fixed digital images in all cases. The patients on the VTC teledermatology arm were also evaluated by videoconference. Finally all patients attended a face-to-face consult, considered the gold standard of patient care. A second dermatologist evaluated the diagnostic and management concordance between the teleconsults and the face-to-face consults.

RESULTS

One-hundred.forty-seven patients completed the study as follows: 74 in the SAF teledermatology arm, 47 in the VTC teledermatology arm and 26 in the conventional consult (control group). The teledermatological (SAF and VTC) and face-to-face evaluations were identical in 100 of 121 patients (82.6%). The errors were mild in 14 cases (11.6%) and severe in 7 (5.8%). The diagnostic concordance was very high (kappa=0,813). The errors grouped by diseases were as follows: 6/54 (11%) for tumors, 10/30 (33.3%) for inflammatory conditions, 1/20 (5%) for infectious diseases, 3/12 (25%) for alopecia/acne and 1/5 (20%) for others. There were 15 errors in the SAF teledermatology arm (20.3%) and 6 in the VTC teledermatology arm (12.8%); these differences were not statistically significant (chi2 1.12; p=0.288).

CONCLUSION

The reliability of dermatological teleconsult is very high, especially for tumoral or infectious diseases. The synchronous interaction with audio requires more resources, is difficult to coordinate and its diagnostic efficacy is not superior to SAF teledermatology.

Introducing the National Library for Health Skin Conditions Specialist Library

BACKGROUND

This paper introduces the new National Library for Health Skin Conditions Specialist Library http://www.library.nhs.uk/skin.

DESCRIPTION

The aims, scope and audience of the new NLH Skin Conditions Specialist Library, and the composition and functions of its core Project Team, Editorial Team and Stakeholders Group are described. The Library's collection building strategy, resource and information types, editorial policies, quality checklist, taxonomy for content indexing, organisation and navigation, and user interface are all presented in detail. The paper also explores the expected impact and utility of the new Library, as well as some possible future directions for further development.

CONCLUSION

The Skin Conditions Specialist Library is not just another new Web site that dermatologists might want to add to their Internet favourites then forget about it. It is intended to be a practical, "one-stop shop" dermatology information service for everyday practical use, offering high quality, up-to-date resources, and adopting robust evidence-based and knowledge management approaches.
