Teledermatology with an integrated nurse-led clinic on the Faroe Islands--7 years' experience

Family recurrence risk of alopecia areata in the Faroe Islands

BACKGROUND

Reports of a positive family history of alopecia areata (AA) have led to the assumption of a genetic component. The Faroe Islands population is small, has been isolated until the 20th century, and is served by only one dermatology clinic, making it highly suitable for genealogical studies.

AIM

To determine the incidence of AA and to estimate the recurrence risk ratio (RRR) in five generations and in a nationwide dermatologist-based AA cohort using the Faroese genealogy database.

METHODS

All registered cases of AA during the period 1973-2011 were identified from the Faroese national dermatology clinics. The AA cases were linked with the genealogy database covering the entire Faroese population, and the probability of AA among first-, second- and third-degree relatives was calculated.

RESULTS

In total, 178 cases of AA were identified, giving a crude incidence of 10.1 per 100 000 person-years (10.9 for women and 9.4 for men). The cumulative incidence proportion over life was 0.8%. There was no apparent trend in the probabilities for AA in first-degree family members compared with second- and third-degree relatives. RRR was > 1 in second-degree family members only.

CONCLUSION

A lower prevalence rate of AA was found than previously published. The genealogical study failed to identify any apparent trend in the RRR estimates, questioning the role of genetic factors in AA in the Faroe Islands. However, it is possible that the trend is masked by bias and low power; larger studies are therefore warranted to estimate the heritability of AA.

Regionale fachärztliche Versorgung und demographischer Wandel in Deutschland - Szenarien zur dermatologischen Versorgung im Jahr 2035

HINTERGRUND

Mithilfe der Bedarfsplanungsrichtlinie des Gemeinsamen Bundesausschusses soll die medizinische Versorgung in Deutschland flächendeckend sichergestellt werden. Kalkulatorische Größe zur Abbildung der räumlichen Versorgungssituation ist der "korrigierte Versorgungsgrad". Vor dem Hintergrund des demographischen Wandels und bereits heute existenter Wiederbesetzungsschwierigkeiten steht die Frage, wie sich die dermatologische Versorgung kleinräumig entwickeln wird.

METHODIK

Mit bundesweiten Daten zu Hautarztstandorten sowie aktuellen und prognostizierten Bevölkerungszahlen auf Kreisebene wurde auf Basis der aktuellen Bedarfsplanungsrichtlinie der korrigierte Versorgungsgrad in drei Wiederbesetzungsszenarien (Szenario 1: 100%ige Wiederbesetzung, Szenario 2: Wegfall eines Arztsitzes je Planungsbereich, Szenario 3: Wegfall von zwei Arztsitzen in ländlichen Planungsbereichen) für das Prognosejahr 2035 exemplarisch berechnet.

ERGEBNISSE

Während sich in Szenario 1 die Versorgungssituation von 2014 auf 2035 in einigen Teilräumen sogar verbessern würde (n = 3 nicht mehr unterversorgt), zeigen die wahrscheinlicheren Szenarien 2 und 3 mit dem Wegfall einzelner Arztstandorte und dem altersselektiven Wanderungsverhalten, dass ganze Regionen in die Unterversorgung gelangen könnten.

SCHLUSSFOLGERUNGEN

Es ist davon auszugehen, dass die räumliche Heterogenität der dermatologischen Versorgung unter Berücksichtigung des demographischen Wandels zunehmen wird. Weitere Anstrengungen in der Bedarfsplanung, aber auch hinsichtlich kreativer Versorgungsmodelle und interkommunaler Kooperation sind erforderlich, um die Versorgung dem demographischen Wandel sowie veränderten Lebensentwürfen junger Mediziner anzupassen.

The Empirical Foundations of Teledermatology: A Review of the Research Evidence

INTRODUCTION

This article presents the scientific evidence for the merit of telemedicine interventions in the diagnosis and management of skin disorders (teledermatology) in the published literature. The impetus for this work derives from the high prevalence of skin disorders, the high cost, the limited availability of dermatologists in certain areas, and the promise of teledermatology to address unmet needs in this area.

MATERIALS AND METHODS

The findings are based on a targeted review of scientific studies published from January 2005 through April 2015. The initial search yielded some 5,020 articles in Google Scholar and 428 in PubMed. A review of the abstracts yielded 71 publications that met the inclusion criteria for this analysis. Evidence is organized according to the following: feasibility and acceptance; intermediate outcomes (use of service, compliance, and diagnostic and treatment concordance and accuracy); outcomes (health improvement and problem resolution); and cost savings. A special section is devoted to studies conducted at the Veterans Health Administration.

RESULTS

Definitions of teledermatology varied across a wide spectrum of skin disorders, technologies, diagnostic tools, provider types, settings, and patient populations. Outcome measures included diagnostic concordance, treatment plans, and health.

CONCLUSIONS

Despite these complexities, sufficient evidence was observed consistently supporting the effectiveness of teledermatology in improving accessibility to specialty care, diagnostic and treatment concordance, and skin care provided by primary care physicians, while also reducing cost. One study reported suboptimal clinical results from teledermatology for patients with pigmented skin lesions. On the other hand, confocal microscopy and advanced dermoscopy improved diagnostic accuracy, especially when rendered by experienced teledermatologists.

Teledermatology update: Mobile teledermatology

Mobile teledermatology is a relatively recent modification of teledermatology, which involves using mobile platforms like cellular phones to transmit images and data for the purpose of teleconsultations. With the rapidly improving quality of smart phone cameras combined with easier access to mobile internet, mobile teledermatology is emerging as a feasible and cost-effective method for teledermatology practice. Mobile teledermatology has shown good results in concordance studies comparing it to face-to-face consultations. Mobile teledermatology can be used for most types of clinical dermatology cases. Mobile teledermatology has been found to be useful in diagnosis, screening and triage of skin lesions including skin cancers. It is also useful as a tool to follow up patients with chronic dermatological problems like psoriasis and chronic wounds. The obvious advantage of mobile teledermatology is it’s cost-effectiveness and the fact that access to expert dermatology care is made easier for patients especially in remote areas. Further research is however required to standardize protocols for mobile teledermatology. Collaborative research among people working in this field would be very useful in this standardization and would help in optimizing the opportunities provided by this interesting tool. This article gives a brief overview of mobile teledermatology including definitions, tools involved, indications, limitations and future applications.
