Fiabilidad de la teledermatología de almacenamiento en un escenario real

Introduction and objectivesAlthough many studies have evaluated the diagnostic reliability of store-and-forward (SF) teledermatology, the reliability of the technique for the diagnosis of general skin conditions in a clinical practice setting has never been demonstrated. We evaluated the reliability of SF teledermatology in clinical practice by analyzing the diagnostic agreement achieved in a subgroup of patients from the DERMATEL-2 study.Material and methodsPatients referred from primary care settings were randomized to 3 groups: SF, a combination of videoconferencing and SF technology (VC-SF), and a control group. This article focuses on the SF group. Clinical data were recorded and photographs taken by primary care physicians, who forwarded the data electronically. Each SF consultation package was assessed by 3 dermatologists (D1,D2,D3). Subsequently all the patients were assessed by a single dermatologist (D1) in a face-to-face consultation. Finally, 2 other dermatologists (D4,D5) assessed the agreement between the diagnoses obtained by SF and FF.ResultsIn total, 457 patients (200 males and 257 females) aged between 2 months and 86 years were randomized (192 to SF, 176 to VC-SF, and 89 to the control group). The diagnostic categories were as follows: tumors (49.4%), inflammatory (25.7%), adnexal (11%), infectious (9.4%) and other processes (4.4%) Since 170 patients had consultations deemed valid for analysis, the study included a total of 510 SF assessments. Most of the images and clinical records were of high quality (71.2% and 91.2% respectively), and diagnostic confidence was high in 81.4% of the cases studied.In 58.4% of cases the condition was managed exclusively by teledermatology. Levels of complete and aggregate interobserver agreement between SF and face-to-face evaluators were 0,72 and 0.90, respectively, for diagnosis and 0.61 and 0.80 for treatment. Diagnostic agreement correlated with the image quality (P  <  .001), diagnostic confidence (P < .001), felt need for conventional consultation (P < .001), and the quality of the clinical record (P = .013).ConclusionThe interobserver reliability of SF diagnosis in clinical practice is good. Dermatologists are able to predict errors in diagnosis by analyzing their own diagnostic confidence and evaluating the quality of the images.     

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

IntroductionThere 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 methodsOne-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.ResultsOne-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 (χ² 1.12; p = 0.288).ConclusionThe 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.     

Comparison of skin biopsy triage decisions in 49 patients with pigmented lesions and skin neoplasms: store-and-forward teledermatology vs face-to-face dermatology

OBJECTIVE: To determine the relative efficacy of store-and-forward teledermatology vs face-to-face dermatology consultations in triage decisions about the need for a biopsy of neoplastic skin changes. DESIGN: Prospective study of consecutive patients judged by an internist to require dermatologic consultation for a skin growth. SETTING: Private primary care and dermatology practices and an academic dermatology practice. PATIENTS: Patients requiring dermatology consultation for evaluation of skin growths. Patients were seen by a single primary care physician between July 10, 1998, and August 4, 2000. INTERVENTION: Digital photographs of skin growths were obtained by the primary care physician and evaluated by a teledermatologist. The patient was then seen face-to-face by a dermatologist. A biopsy was performed if either dermatologist favored biopsy. MAIN OUTCOME MEASURES: Decisions to perform a biopsy. Agreement between the dermatologists was assessed. RESULTS: Of the 49 patients with evaluable photographs, the face-to-face dermatologist and teledermatologist recommended a biopsy for the same 26 patients, yielding a sensitivity of the teledermatologist of 1.00 (95% confidence interval [CI], 0.87-1.00) and a specificity of 1.00 (95% CI, 0.85-1.00). The agreement between the dermatologists (kappa) was 1.00 (95% CI, 0.72-1.00). CONCLUSION: Store-and-forward teledermatology may provide an accurate and cost-effective method of determining whether skin growths in patients presenting to primary care physicians should undergo biopsy.     

Teledermatología. Capacidad para reducir consultas presenciales según el grupo de enfermedad

IntroductionTeledermatology was initially considered useful and cost-effective, especially when distances to the reference hospital were significant. It is currently gaining importance as a more specific tool that can evaluate the need for a rapid referral or to decrease medical costs. The aim of this study was to assess the capacity of teledermatology for resolving cases in different groups of disease.Material and methodsTeleconsultations received in our Department of Dermatology between May 2011 and April 2014 were evaluated according to the virtual diagnosis, the indication given by the dermatologist who evaluated the teleconsultation (discharge/referral), reasons for attending to hospital, reasons for more than one virtual consultation, final face-to-face diagnosis, and diagnostic agreement between the virtual and face-to-face diagnoses.ResultsAn assessment was made on 1163 virtual consultations. Inflammatory diseases were the most frequent diagnosis group (45%). A total of 50.82% of virtual consultations were discharged. The highest resolution rate was achieved by the infectious diseases group, followed by inflammatory diseases (78.4% and 62.8%, respectively). Malignant lesions were referred in nearly all cases (96.7%). The main reason for a referral was the need for diagnostic confirmation or complementary studies (59.8% of all cases). A total of 102 patients received more than one teleconsultation, principally due to incomplete clinical data or poor-quality images. The agreement rate between virtual and face-to-face diagnosis was 88.95%.ConclusionTeledermatology avoids around 50% of the primary care referrals. The highest resolution rate is achieved in the infectious diseases group, followed by the inflammatory diseases group and, secondly, by benign tumours and benign melanocytic lesions.     

Accuracy and reliability of store-and-forward teledermatology: preliminary results from the St George Teledermatology Project

Teledermatology is the practice of dermatology across distances (and time) and involves the transfer of electronic information. To be effective and safe, the teledermatology process needs to demonstrate an acceptable level of accuracy and reliability. Accuracy is reflected by the degree of concordance (agreement) between the teledermatology and face-to-face diagnoses. Reliability is dependent on how consistently a set of results can be reproduced across different operators. Mean concordance (primary diagnoses) achieved by four dermatologists studying 53 store-and-forward diagnostic cases, originating from 49 referred patients, was 79% (range 73-85%). When the differential diagnoses were taken into account, the variation across individual dermatologists narrowed further, with a mean of 86% (range 83-89%). In contrast, the mean general practitioner (GP; n=11) concordance (GP face-to-face vs reference dermatologist store-and-forward diagnoses) was 49%. An interim review of all 49 teledermatology patients showed no adverse outcome at the end of 3 months. The ability to request face-to-face visits by dermatologists, combined with GPs maintaining primary care of the referred patient, serve as additional safeguards for patients using a telemedicine system. Our results indicate that teledermatology management of referred skin complaints is both accurate and reliable.     

Teledermatología prequirúrgica en pacientes con cáncer cutáneo no melanoma. Evaluación económica

IntroductionIn patients with nonmelanoma skin cancer, store-and-forward teledermatology allows satisfactory diagnosis and surgical planning, thus shortening waiting lists and reducing travel requirements for patients in special situations.ObjectiveThe aim of this study was to undertake an economic analysis of presurgical teledermatology, comparing it with a conventional health care approach.Material and methodsThe cost and cost-effectiveness of presurgical teledermatology were analyzed from a societal perspective in the setting of a public hospital with a corporate intranet. The mean delay in surgery was used to measure effectiveness. Over a 12-month period, teledermatology was used in 134 patients with nonmelanoma skin cancer. The unit cost of each intervention (teledermatology and conventional health care approach), the cost ratio between the most and least expensive alternative, and the incremental cost-effectiveness ratio were calculated. We distinguished between 2 groups of patients: those with and those without physical impediments for travel.ResultsThe unit cost of the patients in whom teledermatology was used was €156.40 compared to €278.42 per patient in the conventional system; the conventional system was therefore €1.78 times more expensive than presurgical teledermatology. Teledermatology was more cost-effective, with an incremental cost-effectiveness ratio of €3.10 per patient and per day of delay avoided in patients without impediments for travel and €4.87 in those with impediments for travel.ConclusionTeledermatology used for remote presurgical planning and preparation in patients with nonmelanoma skin cancer is more cost-effective than the conventional referral system in a health setting with a communication network available.     

Minimum Data Set for Incontinence-Associated Dermatitis (MDS-IAD) in adults: Design and pilot study in nursing home residents

Study aimThe aim of this study was to develop a Minimum Data Set for Incontinence-Associated Dermatitis (MDS-IAD), to psychometrically evaluate and pilot test the instrument in nursing homes. Comparable to the MDS for pressure ulcers, the MDS-IAD aims to collect epidemiological data and evaluate the quality of care.Materials and methodsAfter designing and content/face validation by experts and clinicians, staff nurses assessed 108 residents (75.9% female, 77.8% double incontinent) in a convenience sample of five wards. A second nurse independently assessed fifteen residents to calculate inter-rater agreement (p₀) and reliability [Cohen's Kappa (ĸ)].ResultsThe ĸ-value for ‘urinary incontinence’ was 0.68 [95% confidence interval (CI) 0.37–0.99] and 0.55 (95% CI 0.27–0.82) for ‘faecal incontinence’. The p₀ for severity categorisation according to the Ghent Global IAD Categorisation Tool (GLOBIAD) was 0.60. IAD was diagnosed in 21.3% of the residents. IAD management mainly involved the application of a leave-on product (66.7%), no-rinse foams (49.1%), toilet paper (47.9%), and water and soap (38.8%). Fully adequate prevention or treatment was provided to respectively 3.6% and 8.7% of the residents.ConclusionThis instrument provides valuable insights in IAD prevalence at organisational level, will allow benchmarking between organisations, and will support policy makers. Future testing in other healthcare settings is recommended.     

Dental Caries in Adults with Atopic Dermatitis: A Nationwide Cross-Sectional Study in Korea

BackgroundDental caries is the most prevalent chronic infectious oral disease of multifactorial etiology. Increased risk of dental caries development in patients with asthma and allergic rhinitis has been frequently reported. In contrast, only a few studies on dental caries in patients with atopic dermatitis (AD) have been reported.ObjectiveWe investigated the association between AD and dental caries development in an adult population in the Republic of Korea.MethodsA total of 21,606 adults who participated in the Korean National Health and Nutrition Examination Survey, a nationwide, population-based, cross-sectional survey between 2010 and 2015, were included in the study. Multiple logistic regression analyses with confounder adjustment suggested odds ratios (ORs) to identify the possible association between AD and decayed, missing, filled teeth (DMFT) experience compared to non-AD participants. Multiple Poisson regression analyses estimated the mean ratio of the DMFT index according to the presence of AD.ResultsAfter adjusting for various confounding factors, the prevalence of DMFT was significantly associated with AD (OR, 1.58; 95% confidence interval (CI), 1.08~2.29; p=0.017). In addition, the mean value of the DMFT index was significantly different between the AD and non-AD groups (mean ratio, 1.07; 95% CI, 1.00~1.14; p=0.046).ConclusionAD was significantly associated with the development of dental caries. Dermatologists should be aware of the dental manifestations of AD patients and recommend regular dental check-ups for the early detection of caries.     

Estudio comparativo epidemiológico de la enfermedad cutánea en población infantil inmigrante y autóctona en Alicante

IntroductionPrevious studies in Spain have shown that the foreign and immigrant populations can have different diseases to Spanish-born individuals. However, no comparative study has specifically investigated foreign children in Spain.Material and methodsThe objective of the study was to compare skin diseases in foreign children with those in children born in Spain of Spanish parents. We included all patients under 15 years of age who were seen in our dermatology department between January 2007 and December 2007.ResultsDuring the study period, 3108 pediatric patients were seen in the dermatology department. Of these, 2661 (85.6%) were Spanish and 447 (14.3%) were foreigners. Foreign children sought medical care more often (11.4%) than Spanish children (6%) (P < .001) and made less use of the specialist outpatient clinic (59.6% vs 68.8% [P < .001]) and more use of emergency care. Complaints observed more frequently in the foreign children were scabies (adjusted odds ratio [aOR], 10.6; 95% CI, 4.71-24.10), arthropod bites (aOR, 2.80; 95% CI, 1.14-6.87), hypopigmentation (aOR, 2.61; 95% CI, 1.06-6.44), and atopic dermatitis (aOR, 1.65; 95% CI, 1.19-2.31). Melanocytic nevus was observed more frequently in Spanish children (aOR, .50; 95% CI, .30-.83).ConclusionsDifferences between children born in Spain of Spanish parents and foreign children were found for type of visit and frequency of skin diseases.     

Periodontitis en individuos con dermatitis atópica

IntroductionAtopic dermatitis (AD) and periodontitis are chronic inflammatory diseases. To date, the periodontal status of AD patients remains unexplored. The aim of this study was to compare the prevalence and severity of periodontitis in adults with AD and systemically healthy controls.MethodAn observational pilot study was conducted including 23 patients with AD and 23 systemically healthy adults, recruited from Centro Internacional de Estudios Clínicos and the Dental Clinic of Universidad Andrés Bello. The diagnosis of AD was made by a dermatologist based on the medical history and physical examination. All patients received full-mouth periodontal examination and a complete evaluation of their oral hygiene habits.ResultsIndividuals with AD diagnosis presented mild, moderate and severe periodontitis in 33.33%, 38.10% and 28.57% respectively. Systemically healthy controls presented mild periodontitis in 80%, moderate periodontitis in 10% and severe periodontitis in 10%. Individuals with AD showed an increased risk of presenting moderate (OR: 9.14; 95% CI: 1.53-54.54; p = 0.015) or severe periodontitis (OR: 6.85; 95% CI: 1.09-42.75; p = 0.039) compared to controls.ConclusionSubjects with AD presented a higher prevalence of moderate and severe periodontitis compared to systemically healthy controls.     

Urgencias dermatológicas: análisis descriptivo de 861 pacientes en un hospital terciario

Introduction and objectivesMost Spanish hospitals do not have an on-call dermatologist. The primary objective of our study was to determine the profile of patients visiting our hospital's emergency department for dermatologic conditions; our secondary objective was to analyze the case-resolving capacity of the on-call dermatologist.Material and methodsProspective study that included patients with dermatologic conditions treated in the emergency department of a hospital with an on-call dermatology resident during a 2-month period. We collected data on sex, age, diagnosis, days since onset, whether or not the emergency visit was justified, referral (self-referral or other), continued care, and the main reason for the visit. To analyze the case-resolving capacity of the on-call dermatologist we assessed the percentage of direct discharges, the diagnostic tests performed, and the percentage of revisits.ResultsThe on-call dermatologist attended 861 patients (14.4 patients per day), of whom 58% were women and 42% men. In total, 131 different diagnoses were made; the most common were infectious cellulitis, acute urticaria, and herpes zoster. Only half of the visits were justifiable as emergencies (95% of patients < 30 years of age had conditions that did not justify emergency care, compared to 6% of patients > 65 years, P < .005). The on-call dermatologist discharged 58% of the patients directly and the revisit rate was 1%. In 4 of 5 emergency visits no diagnostic tests were required.ConclusionsThe profile of patients seeking emergency dermatologic care is variable. Half of the emergency visits were not justified, and unjustified visits were especially common in younger patients. The case-resolving capacity of the on-call dermatologist was high.     

Correlation between face-to-face assessment and telemedicine for the diagnosis of skin disease in case conferences

BackgroundIn Panama, weekly case conferences are held in which all dermatologists from throughout the country agree on a second opinion for the diagnosis of complicated cases. Unfortunately, patients from the interior of the country may have difficulty attending these case conferences. An alternative in such situations is the use of telemedicine. To date, however, no studies have been undertaken on the effectiveness of this approach in Panama. The aim of this study was to assess the degree of correlation between the diagnoses obtained in case conferences involving face-to-face examination and those involving telemedicine.Material and methodA quasi-experimental nonblinded analysis of correlation was carried out in which dermatologists were randomly assigned to 2 groups: face-to-face examination and telemedicine. Both groups were asked to assess 30 cases and the degree of correlation (Cohen κ coefficient) between the diagnoses made by each group was assessed.ResultsThe patient group included 19 women (63.3%) and 9 patients (30%) were aged between 50 and 59 years. There was a good correlation (κ = 0.6512) between the results of teledermatology and face-to-face examination. Significant differences in the diagnostic skills of the 2 groups were ruled out.ConclusionsTeledermatology can be used effectively to facilitate diagnosis in case conferences involving patients who cannot attend in person (gold standard).     

Geriatric teledermatology: store‐and‐forward vs. face‐to‐face examination

Background Telemedicine could be useful in countries like Italy to meet the needs of elderly patients and in particular in those in precarious general conditions, for whom travelling even short distances can pose considerable practical and economical difficulties. Objective The aim of this study was to determine the efficacy of store‐and‐forward teledermatology vs face‐to‐face consultations in elderly patients. Methods A total of 130 geriatric patients with skin diseases requiring dermatological examination were enrolled. The patients examined, consisting of 60 men (46.15%) and 70 women (53.85%), were aged between 66 and 97 years (mean age 80.58 years). Three dermatologists of the department, with equal experience took turns in face‐to‐face examination and teledermatology (store‐and‐forward). To compare face‐to‐face dermatological examinations with the asynchronous store‐and‐forward approach of teledermatology, we considered diagnostic agreement (ICD‐9 code), therapeutic agreement and concordance of diagnostic confidence. Results One hundred and fourteen of 130 patients were diagnosed with the same ICD‐9 code, making a total observed agreement of 87.7% with a Cohen’s κ estimated of 0.863. Agreement between therapies was 69.6% (Cohen’s κ = 0.640). As it concerns diagnostic confidence, dermatologists appeared generally slightly less certain of their diagnosis by telemedicine. Conclusions Store‐and‐forward teledermatology can improve diagnostic and therapeutic care for skin disease in elderly who lack easy and/or direct access to dermatologists.

Introduction

Teledermatology is the most advanced clinical specialty in telemedicine. The development of teledermatology in specific countries has not been studied in depth.

Patient satisfaction with teledermatology is related to perceived quality of life

BACKGROUND: There is a lack of good data about patient satisfaction with teledermatology and about its potential interaction with quality-of-life factors. OBJECTIVES: To assess the association between perceived skin-related quality of life and patient satisfaction with a nurse-led teledermatology service. METHODS: In a mobile nurse-led teledermatology clinic located in four inner city general practices in Manchester, the teledermatology service used digital cameras to capture and store images of skin conditions for remote diagnosis by dermatologists. One hundred and twenty-three adult patients, non-urgent dermatology referrals from primary care, completed the Dermatology Life Quality Index (DLQI) and a 15-item patient satisfaction questionnaire. RESULTS: In common with other studies of patient satisfaction, subjects reported highly favourable views of 'hotel' aspects of the service (93%) and found it 'convenient' (86%). However, 40% of patients would have preferred to have had a conventional face-to-face consultation with a dermatologist, and 17% felt unable to speak freely about their condition. Patient satisfaction with the service was related to quality of life. Patients reporting lower quality of life as measured by the DLQI were more likely to prefer a face-to-face encounter with a dermatologist (r = 0.216, P < 0.05), and to evince anxiety about being photographed (r = 0.223, P < 0.05). CONCLUSIONS: Patient acceptance and satisfaction with telemedicine services is complicated by patients' subjective health status. Telehealthcare providers need to recognize that patients with poor quality of life may want and benefit from face-to-face interaction with expert clinicians.     

Relationship of Hair Regrowth Pattern in Alopecia Areata Patches According to DIMT Classification with Treatment Modalities and Patch Size: A Retrospective Cross-Sectional Analysis

BackgroundThe morphology of hair regrowth in alopecia areata (AA) patches could be classified into four types, namely diffuse, irregular, marginal, and targetoid patterns, according to the DIMT classification. However, factors affecting hair regrowth patterns have not been investigated.ObjectiveWe investigated whether the DIMT-classified hair regrowth patterns of AA patches are associated with treatment modality and patch size.MethodsWe conducted a retrospective, cross-sectional study of 152 AA patches with hair regrowth.ResultsThe associations between the diffuse pattern and patch size >2 cm (p=0.006; odds ratio [OR]: 0.36, 95% confidence interval [CI]: 0.17~0.74), between the irregular pattern and triamcinolone acetonide intralesional injection (p<0.001; OR: 274.87, 95% CI: 25.75~2,933.56), between the marginal pattern and systemic and topical corticosteroid (p=0.018; OR: 4.89, 95% CI: 1.31~18.27), and between the targetoid pattern and patch size >2 cm (p=0.028; OR: 2.50, 95% CI: 1.10~5.68) were statistically significant.ConclusionTreatment modalities and patch size are the factors affecting hair regrowth patterns in AA patches.
