Structures and performance characteristics of dermatology hospitals in Germany. Current status and long-term development.

BACKGROUND: The objective of the study was to characterize the performance of German dermatology hospitals. METHODS: A structured survey questionnaire was sent out to all dermatology hospitals in October 2019 as part of a cross-sectional analysis based on health care research. RESULTS: Of the 115 hospitals, 95 (82.6 %) responded, including 34 (35.8 %) university hospitals (UC) and 61 (64.2 %) non-university hospitals (NUC), of which 78 % were urban (43 % UC, 57 % NUC) and 22 % rural (10 % UC, 90 % NUC). The dermatology departments comprised an average of 45 inpatient and 11 day-care beds (UC: 52/13, NUC: 40/9). An average of 2,302 inpatients were cared for in 2018 (UC: 2,874, NUC: 1,983), and the case mix index was 0.76 (UC: 0.74, NUC: 0.77, overall range: 0.40-0.96). Mean length of stay was 5.5 days for UC, relevantly lower than 2013 (5.9 days) and 2011 (7.1 days) data, and also significantly lower for NUC at 5.9 (2018) versus 5.1 days (2013). CONCLUSIONS: German dermatology hospitals continue to have a high volume of inpatient care, with a comparison of the last six years again showing a compression with shorter length of stay and higher occupancy density. Dermatological hospitals represent an essential pillar of dermatological care.

Inpatient care for skin diseases in Germany: multi-source analysis on the current and future health care needs.

BACKGROUND: In Germany, skin diseases are mainly treated in the 115 dermatological hospitals. METHODS: Health care and health economic analysis of dermatological inpatient care and prediction of future care needs based on primary and secondary data. RESULTS: Outpatient and inpatient care for dermatologic treatment indications is predominantly provided by dermatology specialists. Inpatient treatment was provided for 833,491 cases in 2018, corresponding to 4.21 % of all inpatient cases (19,808,687). Most common treatment cases were: epithelial skin cancer (total 87,386, of which dermatology clinics 52,608), followed by melanoma (23,917/17,774), psoriasis (19,291/13,352), erysipelas (73,337/11,260), other dermatitis (12,671/10,842), atopic dermatitis (AD) (11,421/9,734), and herpes zoster (26,249/9,652). With an average length of stay of 5.69 days, dermatology hospitals were in the bottom third. The proportion of inpatient indications cared for in dermatology hospitals was highest for prurigo (95.2 %), pemphigus (94.9 %), parapsoriasis (94.6 %), pemphigoid (90.3 %), eczema other than AD (85.6 %), and AD (85.2 %). While the total number of inpatient treatment cases in Germany has increased by an average of 17.5 % between 2000 and 2018, this is the case for 26.6 % of skin diseases and over 150 % for individual ones. The projection of current to future inpatient care suggests a continued high demand for inpatient care by dermatology hospitals. CONCLUSION: Inpatient dermatological care will continue to be an indispensable component of qualified, socially necessary care in Germany.

Patterns of care and follow-up care of patients with uveal melanoma in German-speaking countries: a multinational survey of the German Dermatologic Cooperative Oncology Group (DeCOG).

PURPOSE: Uveal melanoma (UM) is an orphan cancer of high unmet medical need. Current patterns of care and surveillance remain unclear as they are situated in an interdisciplinary setting. METHODS: A questionnaire addressing the patterns of care and surveillance in the management of patients with uveal melanoma was distributed to 70 skin cancer centers in Austria, Germany and Switzerland. Frequency distributions of responses for each item of the questionnaire were calculated. RESULTS: 44 of 70 (62.9%) skin cancer centers completed the questionnaire. Thirty-nine hospitals were located in Germany (88.6%), three in Switzerland (6.8%) and two in Austria (4.5%). The majority (68.2%) represented university hospitals. Most patients with metastatic disease were treated in certified skin cancer centers (70.7%, 29/41). Besides, the majority of patients with UM were referred to the respective skin cancer center by ophthalmologists (87.2%, 34/39). Treatment and organization of follow-up of patients varied across the different centers. 35.1% (14/37) of the centers stated to not perform any screening measures. CONCLUSION: Treatment patterns of patients with uveal melanoma in Germany, Austria and Switzerland remain extremely heterogeneous. A guideline for the treatment and surveillance is urgently needed.

[Medicine and Economy: Measures for a Science Based, Patient-Centred and Resource Conscious Care. The Association of Scientific Medical Societies' (AWMF) Strategy Paper]. / Medizin und Ökonomie: Maßnahmen für eine wissenschaftlich begründete, patientenzentrierte und ressourcenbewusste Versorgung. Ein Strategiepapier der Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF).

The AWMF and its medical societies perceive an increasing dominance of economic targets in the hospital health care sector, leading to impairment of patient care. While resource use in health care should be appropriate, efficient and fairly allocated, "economization" creates a burdensome situation for physicians, nurses and other health care professionals.The AMWF and the medical societies studied causes and developed measures for a scientific, patient-centred and resource-conscious medical care. Disincentives due to the remuneration system, number and equipment of hospitals resp. specialist departments and their basic funding need to be overcome. Proposed actions relate to the patient-doctor-level, the management level of hospitals and the level of planning and financing hospitals including compensation of hospital care. To place patients and their health in the forefront again, joint efforts of all stakeholders in health care are needed.

Socioeconomic Status and the Prevalence of Skin and Atopic Diseases in Five European Countries.

The aim of this study was to investigate the association between socioeconomic status and the prevalence of self-reported skin and atopic diseases in the general population of 5 European countries. A random sample was drawn from the general population aged 18-74 years, based on electoral precincts. Socioeconomic status was estimated by combining net household income with the highest education of respondents. A total of 7,904 subjects were included in this analysis. The lifetime prevalence of "contact dermatitis" ranged from 13.1% (95% confidence interval (95% CI 11.8-14.4%) in subjects with low socioeconomic status, to 19.1% (95% CI 17.5-20.8%) in those with high socio-economic status. In younger subjects skin cancer was more prevalent in the middle or high socioeconomic status groups compared with the low socioeconomic status group (odds ratio 2.4; 95% CI 1.4-4.3); however, this effect was not found in elderly subjects. The lifetime prevalence for at least one atopic disease was 61.2% (95% CI 59.4-63.0%) in the low and 82.8% (95% CI 81.1-84.3%) in the high socioeconomic status group. Individuals with middle or high socioeconomic status reported an overall higher prevalence of skin and atopic diseases compared with those with low socioeconomic status. These findings may reflect differences in reporting, which are likely to result in an underdiagnoses, especially for skin cancer in the younger age groups with low socioeconomic status.

Multicentre cohort study 'Rehabilitation of Occupational Skin Diseases - Optimization and Quality Assurance of Inpatient Management (ROQ)': results from a 3-year follow-up.

BACKGROUND: A tertiary individual prevention programme (TIP) is offered to patients with severe occupational skin disease (OSD) in Germany. Previously, it was shown that the burden of OSDs is considerably reduced in patients up to 1 year after the TIP. OBJECTIVES: To evaluate the long-term effects of the TIP. PATIENTS AND METHODS: In a prospective multicentre cohort study, the clinical and patient-reported outcome data 3 years after the TIP were evaluated. RESULTS: Of the 1788 patients initially included in the study, 1410 were available for the 3-year follow-up analysis. The severity of OSD, the use of topical corticosteroids and days of absence from work were significantly reduced 3 years after the TIP, and the quality of life and skin protective behaviour were significantly improved. Of the patients, 96.9% were able to resume work. One thousand one hundred and sixty-six patients (82.7%) were still working 3 years after the TIP, 874 of them (75.0%) in the same occupational field. Hairdressers had the lowest rate of remaining in their original profession (41.3%). CONCLUSIONS: The follow-up during 3 years of this unique cohort of patients with OSDs shows that the TIP is associated with sustained improvements in terms of disease severity, ability to work, quality of life, and prognosis.

Methods for the Assessment of Barrier Function.

Due to the ease of skin accessibility, a large variety of invasive and noninvasive in vitro and in vivo methods have been developed to study barrier function. The measurement of the transepidermal water loss (TEWL) is most widely used in clinical studies. The different methods of determining TEWL, as well as skin hydration, skin pH, tape stripping and other modern less widely used methods to assess skin barrier function, are reviewed, including Raman spectroscopy and imaging methods such as optical coherence tomography and laser scanning microscopy. The modern imaging methods are important developments in the last decades which, however, determine the structure and, hence, cannot replace the measurement of TEWL in questions related to function.

In vitro assessment of the antimicrobial activity of wound dressings: influence of the test method selected and impact of the pH.

Antibacterial activity of dressings containing antimicrobials is mostly evaluated using in vitro tests. However, the various methods available differ significantly in their properties and results obtained are influenced by the method selected, micro-organisms used, and extraction method, the degree of solubility or the diffusability of the test-compounds. Here, results on antimicrobial activity of silver-containing dressings obtained by agar diffusion test (ADT), challenge tests (JIS L 1902, AATCC 100), and extraction-based methods (microplate laser nephelometry (MLN), luminescent quantification of bacterial ATP (LQbATP)) using Staphylococcus aureus and Pseudomonas aeruginosa were evaluated. Furthermore, the effect of the pH on antibacterial efficacy of these dressings was investigated. All silver-containing dressings exerted antimicrobial activity in all in vitro tests and results correlated considerably well. Differences were observed testing the agent-free basic materials. They did not exhibit any antimicrobial effects in the ADT, MLN or LQbATP, since these methods depend on diffusion/extraction of an active agent. However, they showed a strong antimicrobial effect in the challenge tests as they possess a high absorptive capacity, and are able to bind and sequester micro-organisms present. Therefore, it seems recommendable to choose several tests to distinguish whether a material conveys an active effect or a passive mechanism. In addition, it could be shown that release of silver and its antimicrobial efficacy is partially pH-dependent, and that dressings themselves affect the pH. It can further be speculated that dressings' effects on pH and release of silver ions act synergistically for antimicrobial efficacy.

Cooperation between the occupational health insurance and physicians practicing occupational dermatology: optimization potential in quality assurance.

BACKGROUND: Quality assurance is a task of the medical profession, but it is also a duty of the occupational health insurance (OHI). Data on the interaction quality between physicians practicing occupational dermatology and the OHI are limited. MATERIAL AND METHODS: An online survey was performed in 854 German members of the Working Group on Occupational and Environmental Dermatology in October 2013. Items included demographic data, a judgment on the cooperation between the dermatologists and OHI companies, an economic grading of the current compensation scheme, and prioritization of optimization tasks. RESULTS: 182 members (21.3 % of the invited population) participated in the survey. The cooperation with the OHI companies was judged as "very good" by 10.8 %, as "good" by 56.7  %, as "satisfactory" by 24.2 %, as "sufficient" by 7.0 % and as "inadequate" by 1.3 %. 93.4 % of the interviewed mentioned problems and improvement potentials in the cooperation of their practice or clinic with OHI companies. Main points of criticisms were reimbursement (44.7 %), followed by impairments of the treatment options (36.5 %) and the delay or scope of the treatment in the dermatologist's procedure (29.4 %). CONCLUSIONS: While most physicians practicing occupational dermatology give a positive judgment of their cooperation with OHI companies, quality optimization potentials exist regarding the reimbursement of dermatological services, especially regarding time-intensive counselling in the prevention of occupational skin diseases, in the enablement of diagnostic and therapeutic procedures according to current guidelines and in a timely preventive intervention to use the therapeutic window before chronification of skin diseases may occur.

UV-induced occupational skin cancer: possibilities of secondary individual prevention in the "Dermatologist's Procedure".

Invasive squamous cell carcinoma (SCC) as a "quasi occupational disease" according to §9 Section 2 of the German Social Code Book (SGB) VII typically develops on chronically UV-damaged skin from actinic keratoses. After the Medical Scientific Committee of the Federal Ministry of Labor and Social Affairs has confirmed the legal criteria for acknowledging UV-induced SCC as an occupational disease, it is expected that the condition will be added to the official list of occupational diseases issued by the Federal Government in the near future. The Social Accident Insurance is required by law (§3 Occupational Disease Regulation) to prevent these tumors by "all appropriate means". There are excellent therapeutic and preventive measures for the management of actinic keratoses to avoid the development of SCC. The "Dermatologist's Procedure" according to §§ 41-43 of the agreement between the Social Accident Insurance and the Federal Medical Association was established in Germany in 1972 to take preventive measures in insured persons with skin lesions possibly developing into an occupational disease, or worsening it, or leading to a recurrence of it This procedure proved to be very successful in the prevention of severe and/or recurring skin diseases forcing a worker to leave his job. On the basis of this agreement, the Social Accident Insurance has the instruments to independently provide preventive measures for the new occupational skin disease SCC induced by natural UV light according to §9 Section 2 of the German Social Code Book (SGB) VII.

Teaching interventions in contact dermatitis.

Prevention of occupational contact dermatitis is of utmost significance for both insurers and legislators because it can preserve the individual's ability to work and result in decreased costs for public health. In the last 20 years, many concepts for educational interventions and a multitude of teaching aids have been developed by insurance associations and public institutions from different countries (eg, the United States, Sweden, Denmark, Switzerland, and Germany). For didactic purposes, terms of different levels of prevention have been inaugurated in northern Europe in the context of occupational dermatology. This review presents different educational interventions in the fields of primary, secondary, and tertiary prevention as well as evaluation studies of these measures, especially among health care workers, hairdressers, metalworkers, and bakers' apprentices. Special emphasis is put on the prevention of allergic contact dermatitis.

Silver-loaded seaweed-based cellulosic fiber improves epidermal skin physiology in atopic dermatitis: safety assessment, mode of action and controlled, randomized single-blinded exploratory in vivo study.

BACKGROUND: The epidermal part of the skin is the major interface between the internal body and the external environment. The skin has a specific physiology and is to different degrees adapted for protection against multiple exogenous stress factors. Clothing is the material with the longest and most intensive contact to human skin. It plays a critical role especially in inflammatory dermatoses or skin conditions with an increased susceptibility of bacterial and fungal infections like atopic dermatitis. Previously, we have shown a dose-dependent antibacterial and antifungal activity of silver-loaded seaweed-based cellulosic fibres. AIM OF THE STUDY: We studied the mode of action of silver-loaded seaweed-based cellulosic fiber and performed a broad safety assessment. The principal aim was to analyse the effects of wearing the textile on epidermal skin physiology in 37 patients with atopic dermatitis in a controlled, randomized single-blinded in vivo study. Furthermore, the sensitization potential was tested in a patch test in 111 panellists. RESULTS: We could demonstrate in vitro a dose-dependent scavenging of induced reactive oxygen species by silver-loaded seaweed-based cellulosic fibers. Safety assessment of these fibres showed no detectable release of silver ions. Furthermore, ex vivo assessment after 24 h application both in healthy volunteers and patients with atopic dermatitis by sequential tape stripping and subsequently raster electron microscopy and energy dispersive microanalysis analysis revealed no detectable amounts of silver in any of stratum corneum layers. Serum analysis of silver showed no detectable levels. The in vivo patch testing of 111 volunteers revealed no sensitization against different SeaCell Active (SeaCell GmbH, Rudolstadt, Germany) containing fabrics. The in vivo study on 37 patients with known atopic dermatitis and mild-to-moderate eczema on their arms were randomly assigned to either silver-loaded seaweed fibre T-shirts or to cotton T-shirts for 8 weeks. A significant reduction in Staphylococcus aureus colonization was detectable for the silver T-shirts compared with cotton T-shirts without any changes in non-pathogenic surface bacteria colonization. Furthermore, a more pronounced improvement in barrier function (transepidermal water loss) was observed in mildly involved eczema areas during the first 4 weeks of the study. Stratum corneum hydration and surface pH improved in both treatment groups over time. CONCLUSION: The tested silver-loaded seaweed fibre can be regarded as safe and seams to be suited for application in bio-active textiles in atopic dermatitis based on its positive in vivo activity.
