Attitudes Toward and Use of eHealth Technologies Among German Dermatologists: Repeated Cross-Sectional Survey in 2019 and 2021.

BACKGROUND: In recent years, legal and infrastructural conditions have been set to improve the adoption of digital applications in health care in Germany. The impact of these actions was amplified by the COVID-19 pandemic. So far, no studies have confirmed this progress in dermatology. OBJECTIVE: The aim of this study was to measure changes in knowledge, interest, expectation, and use of digital applications in health care among dermatologists in Germany in 2019 and 2021. METHODS: We administered a repeated cross-sectional survey among dermatologists in medical practices and clinics in Germany at 2 time points: t1 (2019; before the COVID-19 pandemic) and t2 (2021; during the COVID-19 pandemic). We used a standardized questionnaire, including items on respondents' knowledge, interest, expectation, and use of digital applications, as well as their demographics. The survey was distributed by post and email. The data were analyzed descriptively as well as with multiple logistic regressions. RESULTS: At t1, 585 (272/571, 47.6% female; mean age 52.4, SD 8.9 years) dermatologists and at t2, 792 (360/736, 48.9% female; mean age 54.3, SD 8.6 years) dermatologists participated in this survey. Interest in digital medicine was higher at t1 than at t2 (381/585, 65.1% vs 458/792, 57.8%; P≤.001). Nevertheless, 38.6% (306/792) had used digital applications more often since the beginning of the pandemic. For example, real-time telemedicine with patients (12/585, 2.1% vs 160/792, 7.6%; P≤.001) and other specialists did increase (33/385, 5.7% vs 181/792, 22.8%; P≤.001). Almost one-third expressed great concerns about digitalization (272/792, 34.3% vs 294/792, 37.1%; P=.21). Spatial analysis revealed higher interest in, more positive expectations toward, and higher use of digital applications in urban areas in comparison to rural areas. For instance, dermatologists from urban areas assessed future applications as having less risk (adjusted odds ratio [aOR] 0.51, 95% CI 0.35-0.76) than did dermatologists from rural areas. The situation was similar with the age groups, as, for example, dermatologists aged <50 years also expected lower risks (aOR 0.51, 95% CI 0.34-0.77) than those aged ≥50 years. There were no differences between sexes in use, but there were differences in knowledge and expectation; for example, male participants assessed their confidence in using digital applications as higher (aOR 1.44, 95% CI 1.01-2.04) than did female participants. CONCLUSIONS: During the pandemic, the use of digital applications in dermatology increased but still remained at a moderate level. The regional and age-related disparities identified indicate the need for further action to ensure equal access to digital care.

The IMPACT of the COVID-19 Pandemic on Prescription Drug Use in Patients with Psoriasis Vulgaris in Germany.

INTRODUCTION: Real-world evidence (RWE) data is increasingly important to generate rapid insights to effectively manage patient populations. Disruptions like the coronavirus disease 2019 (COVID-19) pandemic may negatively impact the choice of medications used for managing chronic diseases such as psoriasis (PSO). Here, we explored the effect of the COVID-19 pandemic on the sales volumes of treatment guideline-based PSO medication in Germany. METHODS: Patient-level pharmacy dispensing data from the Permea platform, covering approximately 44% of all community pharmacy dispensing in Germany, were analysed from 2019 through to 2021. Patient demographics and PSO indicated medication sales were assessed specifically before and during the pandemic in Germany. RESULTS: We included 6,865,852 sold PSO related drugs from April 2019 to March 2021. Medication sales increased during the pandemic compared with before the pandemic for treatment classes of first-line biological and second-line drugs. The increase was observed across all age groups, but monthly variations could not be detected. Furthermore, we observed increased sales in first-line biological and second-line medications when comparing low to high COVID-19 incidence state. CONCLUSION: Throughout the COVID-19 pandemic the PSO indicated medication sales increased for first-line biological and second-line treatment. This shows that despite the pandemic impact, there continues to be an increase in sales volume for biologics. Only German federal states with intermittently very high COVID-19 incidences show a stagnation in sales volume. The reasons for this need to be investigated in further studies to possibly gain a better understanding of the concerns and uncertainties of patients with PSO.

Digital health interventions in dermatology-Mapping technology and study parameters of systematically identified publications.

Digital health interventions (DHI) potentially improve the efficiency and effectiveness of dermatological care. Currently, an overview clustering and characterizing the evidence on DHIs is missing. This systematic mapping of the literature aims to analyse published research on DHIs in dermatology to identify trends and gaps in research. For this purpose, a systematic search of the MEDLINE database was conducted in August 2022 to identify original publications on DHIs in dermatology. Data on country, targeted audience, DHI category, indication, outcome parameter and study design were extracted. Out of 12,009 records identified in MEDLINE, 403 studies were included in the final analysis. Studies on DHIs mainly performed in western countries, headed by the United States (n = 133), Germany (n = 32) and Spain (n = 23). Of all identified DHIs, 261 targeted healthcare providers (HCP), 66 clients (e.g. patients, caregivers, healthy individuals) and 67 both clients and HCPs. A majority of DHIs focussed on establishing a diagnosis (n = 254). Every other study analysed store-and-forward teledermatology (n = 187), followed by artificial intelligence applications for image analysis (n = 65). The most often analysed DHI category for clients was a support of health behaviour change (n = 31). Monitoring of clients was targeted by 77 studies. Skin cancer (n = 148), wounds (n = 29) and psoriasis (n = 29) were the most targeted indications by DHIs. Most studies analysed diagnostic performance (n = 166), fewer studies analysed acceptance (n = 92) and effectiveness (n = 98). Usability (n = 32) and efficiency (n = 36) were investigated only to a small extent. Studies on DHIs in dermatology have focused on teledermatology and AI applications, with an emphasis on skin cancer diagnosis. Apart from that, a range of DHIs for different user groups, purposes and indications were identified, demonstrating the broad potential for DHIs in dermatology. Further research with a wider set of outcome parameters is needed to fully understand the potential of DHIs and ensure their sustainable implementation into dermatological care.

The Value of Hybrid Teledermatology in German Prisons: Analysis of Routine Telemedical Data.

Introduction: German prisons face organizational and time-consuming difficulties in access to medical specialties. Since 2019, our institute offers interdisciplinary video consultations with spatially independent dermatological support for German prisons. Methods: Documentation of n = 200 consultations between February 2020 and July 2021 with retrospective analysis of dermatological conditions and consultation requests. Results: Most cases (98.0%; 196 of 200) were performed during a regular weekly teleclinic and only few cases on urgent demand. The average duration of the skin disease before request for consultation was 10.3 ± 26.9 months (mean ± standard deviation), the majority had first onset of their disease or acute recurrence of previously known skin diseases. With respect to medical complaints, 39.7% of patients reported severe itch and 7.7% indicated severe pain. For most cases (84.0%), topical treatment and for almost one-third (32.5%) we recommended systemic treatment. The predominant number of cases was only presented once (92.0%) and further treatment of the skin disease could be managed by the medical staff inhouse. Only few consultations could not be solved virtually and were referred to local physicians for face-to-face consultations or procedures. Discussion: Teledermatological care for prisoners effectively supports the inhouse medical resources of prisons. Our interdisciplinary approach enables general practitioners and medical staff of the respective prison to manage the case and shortens the time period until therapy starts.

Measuring Quality of Life in Hidradenitis Suppurativa: Development and Validation of a Disease-specific Patient-reported Outcome Measure for Practice and Research.

Hidradenitis suppurativa is a chronic disease that disrupts patients' physical and psychological well-being. A disease-specific measure was developed and validated for assessing health-related quality of life in hidradenitis suppurativa. After qualitative item development, the quality of life in hidradenitis suppurativa instrument was tested in 101 patients, applying convergent measures and a usability questionnaire. Descriptive and validation-specific analyses were conducted. There was no ceiling, but moderate floor effects (scores between 0 and 3.13 on a scale of 0-4). Few missing values were observed (21 of 23 items < 5%). Internal consistency was satisfying: 2 subscales with 6 and 16 items were identified (Cronbach's alpha=0.95 and 0.88). The quality of life in hidradenitis suppurativa instrument correlated significantly with all convergent criteria (including change in convergent patient-reported outcomes; p < 0.05) except for Hurley stage (p = 0.490). In conclusion, the quality of life in hidradenitis suppurativa questionnaire is an internally consistent, valid, responsive, and usable instrument to assess quality of life in patients with hidradenitis suppurativa.

Documentation of psoriasis in routine care - expert consensus on a German data set.

BACKGROUND AND OBJECTIVES: Documenting patient data in psoriasis clinical practice can improve care, but standardized and transparent documentation is rare. The current project aimed to develop a data set for the documentation of psoriasis in daily practice. MATERIAL AND METHODS: In four online Delphi rounds and one in-person meeting, 27 psoriasis experts allocated variables to a standard, an optimal and an optional data set. Most of the questions were standardized. Open questions were included to allow for the provision of reasons and to enlarge the data sets. Furthermore, in the in-person meeting we considered a) patients' attitudes and b) dermatologists' information on the current usage and acceptability in Germany. RESULTS: The consensus approach resulted in a data set with 69 variables. The standard data set includes 20, the optimal data set 31 and the optional data set 18 variables. In summary, the data set can mainly be grouped into master data, general status and medical history data, medical history of psoriasis, status of psoriasis, diagnostics and comorbidity, therapies and patient-reported outcomes. CONCLUSIONS: The consensus recommendation of a standard, an optimal and an optional data set for routine care of psoriasis intends to be a decision-making aid and an orientation for both daily practice and further development of documentation systems.

Patient-Reported Outcome Measures in Dermatology: A Systematic Review.

By relying on data from existing patient-reported outcome measures of quality of life, the true impact of skin conditions on patients' lives may be underestimated. This study systematically reviewed all dermatology-specific (used across skin conditions) patient-reported outcome measures and makes evidence-based recommendations for their use. The study protocol is registered on PROSPERO (CRD42018108829). PubMed, PsycInfo and CINAHL were searched from inception to 25 June 2018. The Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) criteria were used to assess the measurement properties and methodological quality of studies. A total of 12,925 abstracts were identified. Zero patient-reported outcome measures were assigned to category A (ready for use without further validation), 31 to category B (recommended for use, but only with further validation) and 5 to category C (not recommended for use). There is no gold-standard dermatology-specific patient-reported outcome measure that can be recommended or used without caution. A new measure that can comprehensively capture the impact of dermatological conditions on the patient's life is needed.

How to measure fluctuating impairments in people with MS: development of an ambulatory assessment version of the EQ-5D-5L in an exploratory study.

BACKGROUND: Health fluctuations even within a single day are typical in multiple sclerosis (MS), but are not captured by widely used questionnaires like the EQ-5D-5L. This exploratory study aimed to develop an ambulatory assessment (AA) version of the EQ-5D-5L (EQ-5D-AA) where patients rate their health on mobile phones multiple times per day over several days, and to assess its feasibility and face validity. METHODS: An initial EQ-5D-AA version was based on two patient focus groups. It was then tested and continuously developed in an iterative process: patients completed it over several days, followed by debriefing interviews. Findings were used to refine the EQ-5D-AA, with the resulting version being tested by the subsequent wave of patients until participants declared no need for changes anymore. Before and after the AA period, participants completed the standard paper-based EQ-5D-5L asking about 'today'. RESULTS: Focus group participants reported that their impairments often fluctuated between and within days. They regarded an AA with three assessments per day over seven days most appropriate; assessment should be retrospective to the previous assessment, but not all items should be assessed at each time point. Four waves of AA testing were conducted. Thirteen out of the 17 participants preferred the AA over standard assessment as they regarded it more informative, but not too burdensome. CONCLUSION: The newly developed one-week AA of the EQ-5D-5L captures within-day and day-to-day health fluctuations in people with MS. From the patients' perspective, it is a feasible and face valid way to provide important information beyond what is captured by the standard EQ-5D-5L.

Documenting Patient Data in Psoriasis Clinical Practice-Patient Focus Groups Supporting Psoriasis Experts' Decision-making.

BACKGROUND AND OBJECTIVES: This article presents patients' attitudes about documenting patient data and outcome measures in psoriasis clinical practice to support a Delphi approach of psoriasis experts to develop a standard data set. PATIENTS AND METHODS: We conducted three focus groups with 14 patients in a German outpatient unit for psoriasis. The focus was to explore reasons for and against the documentation of single variables concerning personal, anamnesis, clinical, patient-reported outcomes, and other data. RESULTS: The patients mainly discussed if a variable has an impact on the disease or treatment decision, or if there might be a practical value from experiences with treatments when documented. In addition, in their point of view, patient-reported outcome data are important to document as it enables physicians to learn about a patient's subjective burden of disease. Patient education and the involvement of other physicians in the treatment process also emerged as relevant aspects. CONCLUSION: The results help to understand patients' preferences on documenting patient data and their idea of an exhaustive doctor-patient consultation to improve doctor-patient communication, disease monitoring, and quality of care.

Attitudes towards using electronic health records of patients with psoriasis and dermatologists: a cross-sectional study.

BACKGROUND: Electronic health records (EHRs) offer various advantages for healthcare delivery, especially for chronic and complex diseases such as psoriasis. However, both patients' and physicians' acceptability is required for EHRs to unfold their full potential. Therefore, this study compares patients' and physicians' attitudes towards using EHRs in routine psoriasis care. METHODS: For the purpose of this study, a questionnaire was developed based on literature research and analyses of previously conducted focus groups. Participants completed either a paper-based or an electronic version of the questionnaire. Patient recruitment took place at an dermatological outpatient clinic and via several online pathways (patient associations, and social media). Physicians were recruited via a mailing list of a dermatological association and at a dermatological conference. Patients' and physicians' responses were compared using χ2 tests and Fisher's exact tests. RESULTS: The study consisted of 187 patients and 44 dermatologists. Patients compared to physicians rated almost all potential EHR uses as significantly more important and expected significantly more potential benefits from EHRs. CONCLUSIONS: Patients showed positive expectations towards using EHRs, whereas there was more scepticism in the physician sample. This aligns with previous findings. These differences illustrate the necessity to involve all stakeholders, especially patients and physicians, into the process of developing and implementing EHRs.

New method of measuring subjective well-being: prospective validation study of the 'Daily Experience Sampling Questionnaire' (DESQ) in patients with psoriasis and healthy subjects in Germany.

OBJECTIVES: To validate the newly developed Daily Experience Sampling Questionnaire (DESQ) that measures affective subjective well-being (SWB). The DESQ is an end-of-day diary in which respondents retrospectively rate their SWB at six different, randomly determined moments; it is completed over 1 week. The DESQ shall provide an alternative or complementary approach to existing methods of near-time SWB measurement (experience sampling, Day Reconstruction Method). The primary research objective was to determine criterion validity of the DESQ. DESIGN: Prospective, non-interventional study. SETTING: Participants were recruited in Hamburg, Germany, at a specialised outpatient clinic (patients) and via different channels (healthy participants). PARTICIPANTS: 101 adults with diagnosed and stable psoriasis (46 women, 55 men); 105 adults without psoriasis (49 women, 56 men). PRIMARY AND SECONDARY OUTCOME MEASURES: Participants completed the DESQ for 3 weeks. In weeks 2 and 3, they also performed experience sampling. Criterion validity was determined by weekwise intraclass correlations (ICC) between both methods. Sensitivity to change was determined by the correlation between changes in both methods from weeks 2 to 3. For convergent validity, related concepts such as life satisfaction were measured. Retest reliability was determined using DESQ values of weeks 2 and 3. RESULTS: Criterion validity was excellent (ICC: patients=0.86, 95% CI 0.81 to 0.91; healthy participants=0.86, 95% CI 0.79 to 0.91). Sensitivity to change was r=0.57 and r=0.56, respectively. Correlations with convergent criteria were mostly significant and higher in constructs more proximal to SWB. The ICC indicating retest reliability was 0.77 in patients (95% CI 0.68 to 0.84) and 0.81 in healthy participants (95% CI 0.73 to 0.86). CONCLUSIONS: The DESQ is a valid, reliable and feasible instrument for SWB measurement in people with psoriasis and healthy people. Its approach of end-of-day evaluations of single moments may also lend itself to the measurement of other highly time-variant constructs such as pain, fatigue or depression.

How should electronic health records be designed? A cross-sectional study in patients with psoriasis.

BACKGROUND: Electronic health records (EHRs) are promising tools for routine care. These applications might not only enhance the interaction between patient and physician but also support therapy management. This is crucial in complex and chronic conditions like psoriasis. However, EHRs can only unfold their full potential when being accepted by the users. Therefore, this study aims to analyse how EHRs should be designed for patients with psoriasis and to identify differences between patient subgroups. METHODS: We developed a questionnaire on the acceptability of EHRs based on literature research and results from focus groups. Participants completed a paper-based or electronic version of the questionnaire. We recruited participants at an outpatient clinic as well as online via patient associations and a social media platform. We analysed data using descriptive statistics and bivariate analyses applying Chi-square and Fisher's exact test. RESULTS: The sample encompassed 187 patients with psoriasis. Data reveals that 84.4% of the participants can think of entering data into an EHR. Participants prefer entering data at home (72.2%) instead of entering data in the waiting room (44.9%) and using an own internet-ready device (laptop/computer: 62.6%; smartphone/tablet: 61.5%) instead of a provided device (46.0%). Altogether, 55.6% of participants would accept entering data on a monthly basis when this lasts between one and 10 minutes and further 27.8% would accept even longer lasting data entry. Data privacy is of great concern (e.g. patient should decide who has access to data: 96.7%). Subgroup analyses reveal differences with regard to age, educational level, burden due to psoriasis, number of internet activities, use of electronic questionnaires and mode of administration. CONCLUSION: The high acceptance of entering data is favourable for the implementation of EHRs. The results suggest technical and structural recommendations: Differences between subgroups support the development of flexible EHRs encompassing a basic module, which is expandable with further add-ons, and compatible to different devices. Furthermore, involving patients by entering data into an EHR requires that physicians communicate open-mindedly with the patient and consider data throughout decision-making. Patients should remain owner of their own health data and decide about its processing.

Education in people with venous leg ulcers based on a brochure about compression therapy: A quasi-randomised controlled trial.

Brochures are a useful supplement to patient education. There is increasing evidence that they are an effective medium to support patient satisfaction, adherence, and empowerment. This study aims to produce reliable data on how much patients with venous leg ulcer (VLU) may profit from a brochure that focuses on VLU and on measures and aims of the related compression therapy. The evaluation took part from October 2018 until March 2019 and included 136 patients with VLU and related compression therapy. They were randomly sorted into a case group and a control group of 68 patients each. The case group received a brochure about venous disease and compression therapy and filled in a questionnaire after reading. The questions ranged from basic knowledge about VLU and compression therapy to aspects of self-care. The control group answered the same questions without previous reading of the brochure. The results show that in almost every aspect, the patients in the case group were better informed about their diseases, the compression therapy, and how they may support the measures adequately. This study suggests that patients with VLU may profit from a brochure that explains their disease and the related compression therapy. Better knowledge and understanding may strengthen their empowerment and adherence.

HINTERGRUND: Teledermatologische Anwendungen werden im deutschen Versorgungssystem in den nächsten Jahren erheblich an Bedeutung gewinnen. Das vorliegende Empfehlungspapier wurde als Expertenkonsens auf der Basis einer qualifizierten Literaturrecherche und eines strukturierten Entscheidungsprozesses der Autorengruppe entwickelt. ZIELSETZUNG: a) die IST-Analyse zum Einsatz der Telemedizin in der Dermatologie, b) die Bewertung der Evidenz ihres Nutzens und ihrer Sicherheit und, c) die Entwicklung von Verfahrensstandards für die ärztliche Praxis in den deutschsprachigen Ländern. Auf der Basis dieser Erkenntnisse soll durch einen Expertenkonsens eine Handlungsorientierung für den Einsatz der Teledermatologie gegeben werden. METHODEN: Dreistufiges Vorgehen: 1) Systematische Literaturrecherche in den internationalen medizinischen Onlinedatenbanken Pubmed und Embase, 2) Weitere, teils manuelle Recherchen, 3) Expertenkonsens mit einem systematischen Entscheidungsverfahren mit 21 Teilnehmern. ERGEBNISSE: In der strukturierten Literaturrecherche fanden sich 204 wissenschaftliche Originalarbeiten, in denen Anwendungen der Telemedizin bei Hautkrankheiten thematisiert wurden. Diese wurden systematisch aufgearbeitet, analysiert und bewertet. In der zweiten Stufe wurden in einer Handsuche zusätzliche relevante Schriften identifiziert und ebenfalls ausgewertet. Das Expertengremium entwickelte dann auf der Basis der externen Evidenz sowie der internen Diskussion Handlungsempfehlungen für die Praxis. Schlussfolgerung der wissenschaftlichen Studienlage ist, dass die telemedizinische Unterstützung der dermatologischen Behandlung und Prävention bei Einsatz leistungsfähiger Systeme, Kenntnis ihrer Anwendung sowie Beachtung der Indikationen und Kontrainidikationen einen erheblichen Mehrnutzen darstellt. SCHLUSSFOLGERUNGEN: Die Teledermatologie hat in den deutschsprachigen Ländern wie auch weltweit einen zunehmenden Stellenwert und bietet aufgrund des hohen Innovationsgrades eine Vorreiter- und Vorbildfunktion für weitere telemedizinische Anwendungen anderer Fachrichtungen. Eine qualitätsgesicherte teledermatologische Behandlung ist in den deutschsprachigen Ländern praktikabel und kann zu einem relevanten Mehrnutzen in der Versorgung führen. Ihr Einsatz ist immer dann in Erwägung zu ziehen, wenn relevante Zusatznutzen für die Patienten ohne relevante Nachteile für sie und für die Versorgenden zu erwarten sind. Für die teledermatologische Behandlung wurden mit dem vorliegenden Konsensuspapier praxisrelevante Maßgaben festgelegt. Etwaige situationsabhängige Limitationen in der Versorgung sind stets zu beachten.

How to weight patient-relevant treatment goals for assessing treatment benefit in psoriasis: preference elicitation methods vs. rating scales.

In psoriasis, several patient-relevant treatment goals must be met to be able to consider a treatment beneficial. To assess treatment benefit, the validated questionnaire Patient Benefit Index (PBI) can be used. Its global score summarizes the degree of patient-relevant treatment goals achieved after treatment, weighted by their individual importance on rating scales. These treatment goals have empirically been assigned to five dimensions. While the weighting procedure of the PBI provides information about the importance patients attach to treatment goals on a rating scale from 0 to 4, methods of preference elicitation provide information on how patients would trade off certain treatment goals against each other. However, since the treatment goals defined in the PBI often overlap conceptually, the dimensions of the PBI might be more suitable for exploration in preference elicitation methods. We used an analytic hierarchy process (AHP) and a discrete choice experiment (DCE) to generate preference-based importance weights for the PBI dimensions, and compared these weights to those derived from the rating scales. We were further interested in the effect of importance weights on the calculation of the PBI score. A total of 120 patients with psoriasis completed a questionnaire at baseline, including AHP, DCE and the rating scales, and at follow-up, regarding the attainment of treatment goals, to calculate the PBI score. In contrast to the results derived from the average rating scores, use of AHP and DCE resulted in both similar importance weights and rankings of dimensions. Presumably, patients rated treatment goals differently than the respective dimension they belong to. However, the differently calculated importance weights led to similar values of the PBI score. Our findings nevertheless provide clear evidence that, regardless of the method used, the importance of treatment goals differs between psoriasis patients, and this should be reflected in treatment decisions.

[Antidepressive Combination Treatment in Patients with Severe Depressive Episode: The Practice of Prescription in a Clinical Sample 2012]. / Antidepressive Kombinationsbehandlung bei Patienten mit schwerer depressiver Episode: Verordnungspraxis am Beispiel einer klinischen Stichprobe 2012.

Objectives Polypharmacy in the treatment of severe psychiatric disorders may include promising treatment options, yet may also be subject to additional side effects and interactions. In patients with severe depression, the prevalence of antidepressive (AD) combination treatment has not been thoroughly assessed yet. Methods We assessed the prevalence of antidepressive combination treatment in a sample of hospital patients at the LVR-Clinic in Düsseldorf, Germany in 2012. Results 1.198 residential or semi-residential patients were diagnosed with severe depressive episode and were treated with at least one antidepressant. 25.1 % of those received a combination of at least two antidepressants. The most frequent combination approaches were tri- and tetracyclic AD with selective serotonin reuptake inhibitors (SSRI) yet various other combination approaches were observed. Conclusions Combination treatment is a common strategy. Future trends could be monitored via electronic prescription software, yet prospective confirmatory trials are needed to assess the rationale of different combination treatment approaches.
