Handlungsempfehlungen für die planerische Steuerung der Krankenhausversorgung in Nordwestdeutschland

Umstrukturierungen in der Krankenhauslandschaft, insbesondere Schließungen sowie Zusammenlegungen kleinerer Klinikstandorte zu Zentralkliniken jenseits Zentraler Orte, stellen Herausforderungen an die wohnortnahe Versorgung und eine zukunftsfähige Raumstruktur. Die Förderung und der Erhalt gleichwertiger Lebensbedingungen sowie die Sicherung der Daseinsvorsorge im Hinblick auf ein leistungsfähiges und effektives Standortsystem der Krankenhaus- und Gesundheitsversorgung sind infrage gestellt. Es bedarf einer stärkeren raumordnerischen Steuerung sowie einer vorausschauenden, länderübergreifenden und kriterienbasierten Krankenhausplanung. Ein Ansatz zur Effizienzsteigerung ist die Stärkung der sektorenübergreifenden und interdisziplinär fachübergreifenden Versorgung. Für die Gestaltung der künftigen Krankenhauslandschaft sind neben raumordnerischen Kriterien insbesondere die Anforderungen der verschiedenen Nutzer/innengruppen zu berücksichtigen. Zudem bedarf es digitaler Daten für detaillierte Versorgungs- und Erreichbarkeitsanalysen als Planungsgrundlage.Current development trends in the restructuring of the hospital landscape, in particular the mergers of smaller hospitals into central hospitals beyond the central-places system, pose challenges for a sustainable spatial structure. The objectives of spatial planning and development are to ensure the provision of public services, the promotion and preservation of equal living conditions, and an efficient and effective system of hospital and health care locations. This requires spatial planning and governance, which should be based on the central-place system, as well as on a forward- looking, cross-state and criteria-based hospital planning. One approach to increase efficiency is an intersectoral and interdisciplinary care. In addition to regional planning criteria, the requirements of the various user groups are important for the designing of the future hospital landscape. In addition, digital data is required for detailed supply and accessibility analyses as a basis for planning

Teledermatology: Comparison of Store-and-Forward Versus Live Interactive Video Conferencing

A decreasing number of dermatologists and an increasing number of patients in Western countries have led to a relative lack of clinicians providing expert dermatologic care. This, in turn, has prolonged wait times for patients to be examined, putting them at risk. Store-and-forward teledermatology improves patient access to dermatologists through asynchronous consultations, reducing wait times to obtain a consultation. However, live video conferencing as a synchronous service is also frequently used by practitioners because it allows immediate interaction between patient and physician. This raises the question of which of the two approaches is superior in terms of quality of care and convenience. There are pros and cons for each in terms of technical requirements and features. This viewpoint compares the two techniques based on a literature review and a clinical perspective to help dermatologists assess the value of teledermatology and determine which techniques would be valuable in their practice

Dermatologist-like explainable AI enhances trust and confidence in diagnosing melanoma

Although artificial intelligence (AI) systems have been shown to improve the accuracy of initial melanoma diagnosis, the lack of transparency in how these systems identify melanoma poses severe obstacles to user acceptance. Explainable artificial intelligence (XAI) methods can help to increase transparency, but most XAI methods are unable to produce precisely located domain-specific explanations, making the explanations difficult to interpret. Moreover, the impact of XAI methods on dermatologists has not yet been evaluated. Extending on two existing classifiers, we developed an XAI system that produces text and region based explanations that are easily interpretable by dermatologists alongside its differential diagnoses of melanomas and nevi. To evaluate this system, we conducted a three-part reader study to assess its impact on clinicians' diagnostic accuracy, confidence, and trust in the XAI-support. We showed that our XAI's explanations were highly aligned with clinicians' explanations and that both the clinicians' trust in the support system and their confidence in their diagnoses were significantly increased when using our XAI compared to using a conventional AI system. The clinicians' diagnostic accuracy was numerically, albeit not significantly, increased. This work demonstrates that clinicians are willing to adopt such an XAI system, motivating their future use in the clinic

A skin cancer prevention facial-aging mobile app for secondary schools in Brazil : appearance-focused interventional study.

Background: The incidence of melanoma is increasing faster than any other major cancer both in Brazil and worldwide. Southeast Brazil has especially high incidences of melanoma, and early detection is low. Exposure to ultraviolet (UV) radiation is a primary risk factor for developing melanoma. Increasing attractiveness is a major motivation among adolescents for tanning. A medical student-delivered intervention that takes advantage of the broad availability of mobile phones and adolescents? interest in their appearance indicated effectiveness in a recent study from Germany. However, the effect in a high-UV index country with a high melanoma prevalence and the capability of medical students to implement such an intervention remain unknown. Objective: In this pilot study, our objective was to investigate the preliminary success and implementability of a photoaging intervention to prevent skin cancer in Brazilian adolescents. Methods: We implemented a free photoaging mobile phone app (Sunface) in 15 secondary school classes in southeast Brazil. Medical students ?mirrored? the pupils? altered 3-dimensional (3D) selfies reacting to touch on tablets via a projector in front of their whole grade accompanied by a brief discussion of means of UV protection. An anonymous questionnaire capturing sociodemographic data and risk factors for melanoma measured the perceptions of the intervention on 5-point Likert scales among 356 pupils of both sexes (13-19 years old; median age 16 years) in grades 8 to 12 of 2 secondary schools in Brazil. Results: We measured more than 90% agreement in both items that measured motivation to reduce UV exposure and only 5.6% disagreement: 322 (90.5%) agreed or strongly agreed that their 3D selfie motivated them to avoid using a tanning bed, and 321 (90.2%) that it motivated them to improve their sun protection; 20 pupils (5.6%) disagreed with both items. The perceived effect on motivation was higher in female pupils in both tanning bed avoidance (n=198, 92.6% agreement in females vs n=123, 87.2% agreement in males) and increased use of sun protection (n=197, 92.1% agreement in females vs n=123, 87.2% agreement in males) and independent of age or skin type. All medical students involved filled in a process evaluation revealing that they all perceived the intervention as effective and unproblematic, and that all pupils tried the app in their presence. Conclusions: The photoaging intervention was effective in changing behavioral predictors for UV protection in Brazilian adolescents. The predictors measured indicated an even higher prospective effectiveness in southeast Brazil than in Germany (>90% agreement in Brazil vs >60% agreement in Germany to both items that measured motivation to reduce UV exposure) in accordance with the theory of planned behavior. Medical students are capable of complete implementation. A randomized controlled trial measuring prospective effects in Brazil is planned as a result of this study

Erythromelanosis Follicularis Faciei et Colli: A Case Report in a Caucasian Male and Brief Review of the Literature

Erythromelanosis follicularis faciei et colli, a rare condition of unknown etiology, was first described by Kitamura et al. from Japan in 1960. It is characterized by a triad consisting of well-demarcated erythema, hyperpigmentation, and follicular papules. We report the case of a 50-year-old Caucasian male, who had asymptomatic symmetrical facial lesions since the age of 42. His family history was unremarkable. Published erythromelanosis follicularis faciei et colli cases of the last 10 years are summarized in this report to demonstrate the variability and differences in the clinical presentation of this uncommon diagnosis

Discontinuation of Fumaric Acid Esters is Affected by Depressive Symptomatology: A Retrospective Analysis

Fumaric acid esters (FAEs) remain a widespread therapy option for moderate-to-severe psoriasis. However, drug survival of FAEs is limited by adverse events (AEs) or inadequate treatment response. Depressive disturbances are highly prevalent in psoriasis patients and are hypothesized to be associated with the reporting of AEs and therapy discontinuation. This study’s aim was to analyze whether psoriasis patients with comorbid depressive symptomatology are more likely to discontinue treatment with FAEs due to AEs and/or inadequate treatment response. Data were retrospectively extracted from the records of patients starting therapy with FAEs in the Department of Dermatology, University Hospital Essen, Germany between 2017 and 2022, covering the first 52 weeks of treatment. Psoriasis severity and depressive symptomatology, as well as AEs and therapy discontinuation, were analyzed. Psoriasis patients (N = 95, 47.37% female) with depressive symptomatology (42.11%) were more likely to discontinue therapy due to patient-reported AEs, while the total number of reported AEs was not associated with depression. The results support the hypothesis that among psoriasis patients with depressive symptoms, the associated introspection and somatization may result in increased sensitivity for AEs and thus in quicker therapy discontinuation. In these patients, the occurrence of nocebo effects should be minimized, e.g. by special communication techniques

How familiar are German dermatologists with placebo and nocebo effects and to what extent are these targeted in clinical practice: A survey within the dermatological community

Background: Every medical treatment inevitably comprises not only physiological, but also psychological components, reflected by placebo and nocebo effects, which significantly affect treatment outcome. However, the extent of knowledge on the mechanisms steering placebo and nocebo effects in the dermatological community in Germany is currently unclear. Objectives: To assess the state of knowledge about placebo and nocebo effects in the German dermatological community, to evaluate whether this knowledge is already being used in clinical practice, and to investigate whether German dermatologists are interested in learning more about the topic. Methods: German Dermatologists, the majority working in their own practice, were asked to fill in an online survey addressing the knowledge about placebo and nocebo effects and the feasibility of special techniques to enhance placebo and minimize nocebo effects within the clinical routine. Results: N = 154 complete (79%) or partial (21%) responses to the survey were recorded in the online database and included in the analysis. All participants reported to know what the placebo effect is and 59.7% (74/124) indicated that they already had experience with prescribing or recommending a treatment without active substances. In contrast, only 62.0% (80/129) stated to know what the nocebo effect is. Participants showed a rather superficial knowledge regarding placebo and nocebo mechanisms. The majority of participants (76.7%, 99/129) expressed their willingness to be further educated about the underlying mechanisms mediating placebo and nocebo effects and the possible application in clinical practice. Conclusions: The current survey offers a so far unique insight into the state of knowledge of German dermatologists on placebo and nocebo effects. The results indicate a need for education about this topic. Encouragingly, however, German dermatologists considered communication strategies to maximize placebo and reduce nocebo effects and expressed motivation to be trained to implement these strategies in everyday clinical practice

A brief screening tool for depression in psoriasis patients: The Two Questions Test in clinical practice

Patients suffering from chronic inflammatory diseases such as psoriasis are prone to develop depressive symptoms. However, within the time constraints of dermatological clinics, depressive symptoms in psoriasis patients are often overlooked and thus underdiagnosed. The Two Questions Test may serve as a quick screening tool for an initial assessment of depressive burden in these patients. We evaluated its usefulness in the clinical context analyzing the records of patients starting systemic treatment for psoriasis with a selective interleukin (IL)23- or IL17A-inhibitor. In a total sample of N = 139 patients, baseline Two Questions Test scores were analyzed together with measures of psoriatic and psychiatric symptoms. In addition, the development of the Two Questions Test scores over the course of the first 28 weeks of treatment was assessed. No association was found between the Two Questions Test scores and skin symptoms measured by the Psoriasis Area and Severity Index and the visibility of skin lesions. However, skin related quality of life analyzed with the Dermatology Life Quality Index was associated with the Two Questions Test scores. In addition, the longitudinal analysis revealed improvement in Two Questions Test outcomes over the course of patients’ treatment. These results indicate the Two Questions Test's usefulness both as an initial screening tool of depressive symptoms, as well as in its use as a sensitive tool for the repeated assessment of depressive symptoms in psoriasis patients
