Digital Medication Management in Polypharmacy­Findings of a Cluster-Randomized, Controlled Trial With a Stepped-Wedge Design in Primary Care Practices (AdAM).

BACKGROUND: Inappropriate drug prescriptions for patients with polypharmacy can have avoidable adverse consequences. We studied the effects of a clinical decision-support system (CDSS) for medication management on hospitalizations and mortality. METHODS: This stepped-wedge, cluster-randomized, controlled trial involved an open cohort of adult patients with polypharmacy in primary care practices (=clusters) in Westphalia-Lippe, Germany. During the period of the intervention, their medication lists were checked annually using the CDSS. The CDSS warns against inappropriate prescriptions on the basis of patient-related health insurance data. The combined primary endpoint consisted of overall mortality and hospitalization for any reason. The secondary endpoints were mortality, hospitalizations, and high-risk prescription. We analyzed the quarterly health insurance data of the intention-to-treat population with a mixed logistic model taking account of clustering and repeated measurements. Sensitivity analyses addressed effects of the COVID-19 pandemic and other effects. RESULTS: 688 primary care practices were randomized, and data were obtained on 42 700 patients over 391 994 quarter years. No significant reduction was found in either the primary endpoint (odds ratio [OR] 1.00; 95% confidence interval [0.95; 1.04]; p = 0.8716) or the secondary endpoints (hospitalizations: OR 1.00 [0.95; 1.05]; mortality: OR 1.04 [0.92; 1.17]; high-risk prescription: OR 0.98 [0.92; 1.04]). CONCLUSION: The planned analyses did not reveal any significant effect of the intervention. Pandemic-adjusted analyses yielded evidence that the mortality of adult patients with polypharmacy might potentially be lowered by the CDSS. Controlled trials with appropriate follow-up are needed to prove that a CDSS has significant effects on mortality in patients with polypharmacy.

Risk factors for herpes zoster infections: a systematic review and meta-analysis unveiling common trends and heterogeneity patterns.

PURPOSE: The burden of herpes zoster (HZ) is substantial and numerous chronic underlying conditions are known as predisposing risk factors for HZ onset. Thus, a comprehensive study is needed to synthesize existing evidence. This study aims to comprehensively identify these risk factors. METHODS: A systematic literature search was done using MEDLINE via PubMed, EMBASE and Web of Science for studies published from January 1, 2003 to January 1, 2023. A random-effects model was used to estimate pooled Odds Ratios (OR). Heterogeneity was assessed using the I2 statistic. For sensitivity analyses basic outlier removal, leave-one-out validation and Graphic Display of Heterogeneity (GOSH) plots with different algorithms were employed to further analyze heterogeneity patterns. Finally, a multiple meta-regression was conducted. RESULTS: Of 6392 considered records, 80 were included in the meta-analysis. 21 different conditions were identified as potential risk factors for HZ: asthma, autoimmune disorders, cancer, cardiovascular disorders, chronic heart failure (CHF), chronic obstructive pulmonary disorder (COPD), depression, diabetes, digestive disorders, endocrine and metabolic disorders, hematological disorders, HIV, inflammatory bowel disease (IBD), mental health conditions, musculoskeletal disorders, neurological disorders, psoriasis, renal disorders, rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and transplantation. Transplantation was associated with the highest risk of HZ (OR = 4.51 (95% CI [1.9-10.7])). Other risk factors ranged from OR = 1.17-2.87, indicating an increased risk for all underlying conditions. Heterogeneity was substantial in all provided analyses. Sensitivity analyses showed comparable results regarding the pooled effects and heterogeneity. CONCLUSIONS: This study showed an increased risk of HZ infections for all identified factors.

The Relationship of Continuity of Care, Polypharmacy and Medication Appropriateness: A Systematic Review of Observational Studies.

INTRODUCTION: Worldwide, polypharmacy and medication appropriateness-related outcomes (MARO) are growing public health concerns associated with potentially inappropriate prescribing, adverse health effects, and avoidable costs to health systems. Continuity of care (COC) is a cornerstone of high-quality care that has been shown to improve patient-relevant outcomes. However, the relationship between COC and polypharmacy/MARO has not been systematically explored. OBJECTIVE: The aim of this systematic review was to investigate the operationalization of COC, polypharmacy, and MARO as well as the relationship between COC and polypharmacy/MARO. METHODS: We performed a systematic literature search in PubMed, Embase, and CINAHL. Quantitative observational studies investigating the associations between COC and polypharmacy and/or COC and MARO by applying multivariate regression analysis techniques were eligible. Qualitative or experimental studies were not included. Information on the definition and operationalization of COC, polypharmacy, and MARO and reported associations was extracted. COC measures were assigned to the relational, informational, or management dimension of COC and further classified as objective standard, objective non-standard, or subjective. Risk of bias was assessed by using the NIH Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. RESULTS: Twenty-seven studies were included. Overall, substantial differences existed in terms of the COC dimensions and related COC measures. Relational COC was investigated in each study, while informational and management COC were only covered among three studies. The most frequent type of COC measure was objective non-standard (n = 16), followed by objective standard (n = 11) and subjective measures (n = 3). The majority of studies indicated that COC is strongly associated with both polypharmacy and MARO, such as potentially inappropriate medication (PIM), potentially inappropriate drug combination (PIDC), drug-drug interaction (DDI), adverse drug events (ADE), unnecessary drug use, duplicated medication, and overdose. More than half of the included studies (n = 15) had a low risk of bias, while five studies had an intermediate and seven studies a high risk of bias. CONCLUSIONS: Differences regarding the methodological quality of included studies as well as the heterogeneity in terms of the operationalization and measurement of COC, polypharmacy, and MARO need to be considered when interpreting the results. Yet, our findings suggest that optimizing COC may be helpful in reducing polypharmacy and MARO. Therefore, COC should be acknowledged as an important risk factor for polypharmacy and MARO, and the importance of COC should be considered when designing future interventions targeting these outcomes.

[Concepts and application of cost-benefit evaluation in an international overview]. / Grundkonzepte und Einsatz von Kosten-Nutzen-Bewertungen im internationalen Überblick.

Due to market access of high-priced new drugs, the financial burden on the health care system and the appropriateness of drug prices are often doubted. Is it time for a broader perspective of health technology assessment in Germany, which has so far focused on clinical value? Should cost and benefit aspects of new technologies be given equal weight in future assessments of market access for new technologies? The experiences of European neighbors and the Standing Committee on Vaccination with cost-benefit analyses are encouraging. Introducing cost-benefit analyses as a further decision criterion in the pricing of new technologies naturally creates additional work for the players involved but also offers the opportunity to provide transparent and understandable answers to the question of what a health improvement is worth. In view of the increasing funding challenges facing the statutory health insurance system in Germany, this question will continue to gain importance.

Healthcare resource utilization and costs in 23-25-year-old women with human papillomavirus (HPV) associated anogenital diseases in Germany - a retrospective analysis of statutory health insurance claims data.

BACKGROUND: Human papilloma virus (HPV) causes multiple anogenital diseases including cervical cancer and is the most common sexually transmitted infection. Healthcare resource utilization (HRU) associated with HPV-related anogenital diseases includes diagnostic and disease specific treatment regimens. A recent study showed disease burden of young women aged 23-25 years, who were the first populations eligible to receive HPV vaccination after its introduction in Germany. Cost for the German statutory health insurance (SHI) due to HPV­related anogenital diseases in this population are unknown. This study aimed at assessing HRU and costs related to HPV-associated anogenital diseases for the Germany SHI. METHODS: We used a retrospective, matched cohort design to leverage the prior identified cohort of 23-25-year-old women born between 1989-1992 diagnosed with HPV-related anogenital disease from the Institute for Applied Health Research Berlin (InGef) Research Database. German SHI claims data from 2012-2017 were analyzed. The prior identified cases were matched (direct, without replacement) to women without anogenital diseases (1:10 ratio). HRU and costs for inpatient care, outpatient care, and pharmaceutical during a 3-year observation period were determined for both cases and controls and increments between the groups were assessed. RESULTS: 2,972 women diagnosed with anogenital diseases (cases) who were matched to 29,720 women without anogenital diseases (controls). Cases had more outpatient visits (52.4 visits vs. 39.2 visits) and more cases (45.2% vs. 31.7%) were hospitalized at least once in the 3­year observation period. Most common outpatient procedures performed in cases were conization of the cervix uteri (4.4% cases; n < 5 controls), followed by other excision and destruction of diseased tissue of the cervix uteri (3.1% in cases; 0.0% in controls). Median difference in total healthcare costs of €684 (mean difference: €1,089, 95%CI: €752-1,426) suggest that HPV-related anogenital diseases were responsible for approximately €3.2 Million more healthcare costs for the identified cases in the four birth cohorts within the 3­year observation period in the InGef Research Database. Costs were mainly driven by outpatient care (41.6% of total costs). CONCLUSION: In Germany, HPV-related anogenital diseases among young women are associated with considerable HRU and financial expenditures, mostly driven by outpatient care.

Financial toxicity in cancer patients treated with radiotherapy in Germany-a cross-sectional study.

PURPOSE: Financial toxicity arises in cancer patients from subjective financial distress due to objective financial burden from the disease or treatment. Financial toxicity associates with worse outcomes. It has not been described in cancer patients undergoing radiotherapy in Germany and its publicly funded health system. In this context, we therefore investigated the prevalence of financial toxicity, associated risk factors, and patient preferences on communication of financial burden. METHODS: We conducted a preregistered ( https://doi.org/10.17605/OSF.IO/KH6VX ) cross-sectional study surveying patients at the end of their course of radiotherapy in two institutions. Objective financial burden was assessed by direct costs and loss of income. Financial toxicity was measured by subjective financial distress per EORTC QLQ-C30. We used Spearman's correlation and Fisher's exact test for univariate analysis, an ordinal regression for multivariate analysis. A p-value < 0.05 was considered statistically significant. RESULTS: Of the 100 patients participating in the study, 68% reported direct costs, 25% loss of income, and 31% subjective financial distress. Per univariate analysis, higher subjective financial distress was significantly associated with active employment, lower quality of life, lower household income, higher direct costs, and higher loss of income. The latter three factors remained statistically significant in the multivariate analysis. A relative majority of the patients welcomed communication regarding financial burden with their radiation oncologist. CONCLUSION: Financial toxicity is prevalent in cancer patients treated with radiotherapy in Germany. The reported risk factors may help to identify patients at risk. Future studies should validate these results and investigate interventions for financial toxicity to potentially improve outcomes.

Burden of CIN2+ diagnoses and conizations in women aged 18-45 years-a retrospective secondary data analysis of German statutory health insurance claims data.

PURPOSE: High grade cervical intraepithelial neoplasia (CIN2+) may progress to cervical cancer. They may be detected by screening and are usually treated by conization. This study aimed at assessing annual proportions of screening, prevalent and incident CIN2+ diagnoses, as well as proportions of (re-)conizations during 24 months follow-up after conization in Germany. METHODS: A descriptive retrospective claims data analysis of the years 2013-2018 was conducted using the InGef Research Database. Women aged 18-45 years with CIN2+ diagnoses were identified by ICD-10-GM codes (N87.1, N87.2, D06.-, and C53.-). Cervical conizations were identified by OPS codes (5-671.0* or 5-671.1*). Screening participation was identified by EBM codes (01730, 01733, 32819 or 32820). Annual proportions were calculated as women with the respective documented codes divided by all women in the respective age group per calendar year. RESULTS: Overall annual proportions of screened women spanned from 60.01 to 61.33% between 2013 and 2018. The overall annual prevalence of CIN2+ diagnoses (regardless of screening participation) ranged from 0.72 to 0.84% between 2013 and 2018, with highest proportions observed in women aged 27-45 years. Also, CIN2+ incidence was highest in women 27-45 years. Annual proportion of women undergoing conization was 0.24% in 2013 and 0.21% in 2018. During a 24-month follow-up period after conization, 2.91% of women underwent a re-conization 3 months or later after the initial conization. CONCLUSION: This analysis demonstrates a considerable burden of CIN2+, conizations and re-conizations in Germany, especially in women aged 27-45 years. This highlights the need for intensified prevention efforts such as expanding human papillomavirus (HPV) vaccination.

An Innovative Telemedical Network to Improve Infectious Disease Management in Critically Ill Patients and Outpatients (TELnet@NRW): Stepped-Wedge Cluster Randomized Controlled Trial.

BACKGROUND: Evidence-based infectious disease and intensive care management is more relevant than ever. Medical expertise in the two disciplines is often geographically limited to university institutions. In addition, the interconnection between inpatient and outpatient care is often insufficient (eg, no shared electronic health record and no digital transfer of patient findings). OBJECTIVE: This study aims to establish and evaluate a telemedical inpatient-outpatient network based on expert teleconsultations to increase treatment quality in intensive care medicine and infectious diseases. METHODS: We performed a multicenter, stepped-wedge cluster randomized trial (February 2017 to January 2020) to establish a telemedicine inpatient-outpatient network among university hospitals, hospitals, and outpatient physicians in North Rhine-Westphalia, Germany. Patients aged ≥18 years in the intensive care unit or consulting with a physician in the outpatient setting were eligible. We provided expert knowledge from intensivists and infectious disease specialists through advanced training courses and expert teleconsultations with 24/7/365 availability on demand respectively once per week to enhance treatment quality. The primary outcome was adherence to the 10 Choosing Wisely recommendations for infectious disease management. Guideline adherence was analyzed using binary logistic regression models. RESULTS: Overall, 159,424 patients (10,585 inpatients and 148,839 outpatients) from 17 hospitals and 103 outpatient physicians were included. There was a significant increase in guideline adherence in the management of Staphylococcus aureus infections (odds ratio [OR] 4.00, 95% CI 1.83-9.20; P<.001) and in sepsis management in critically ill patients (OR 6.82, 95% CI 1.27-56.61; P=.04). There was a statistically nonsignificant decrease in sepsis-related mortality from 29% (19/66) in the control group to 23.8% (50/210) in the intervention group. Furthermore, the extension of treatment with prophylactic antibiotics after surgery was significantly less likely (OR 9.37, 95% CI 1.52-111.47; P=.04). Patients treated by outpatient physicians, who were regularly participating in expert teleconsultations, were also more likely to be treated according to guideline recommendations regarding antibiotic therapy for uncomplicated upper respiratory tract infections (OR 1.34, 95% CI 1.16-1.56; P<.001) and asymptomatic bacteriuria (OR 9.31, 95% CI 3.79-25.94; P<.001). For the other recommendations, we found no significant effects, or we had too few observations to generate models. The key limitations of our study include selection effects due to the applied on-site triage of patients as well as the limited possibilities to control for secular effects. CONCLUSIONS: Telemedicine facilitates a direct round-the-clock interaction over broad distances between intensivists or infectious disease experts and physicians who care for patients in hospitals without ready access to these experts. Expert teleconsultations increase guideline adherence and treatment quality in infectious disease and intensive care management, creating added value for critically ill patients.

Use of an electronic medication management support system in patients with polypharmacy in general practice: study protocol of a quantitative process evaluation of the AdAM trial.

BACKGROUND: Interventional studies on polypharmacy often fail to significantly improve patient-relevant outcomes, or confine themselves to measuring surrogate parameters. Interventions and settings are complex, with many factors affecting results. The AdAM study's aim is to reduce hospitalization and death by requiring general practitioners (GPs) to use a computerized decision-support system (CDSS). The study will undergo a process evaluation to identify factors for successful implementation and to assess whether the intervention was implemented as intended. OBJECTIVE: To evaluate our complex intervention, based on the Medical Research Council's guideline dimensions. RESEARCH QUESTIONS: We will assess implementation (reach, fidelity, dose, tailoring) by asking: (1) Who took part in the intervention (proportion of GPs using the CDSS, proportion of patients enrolled in them)? Information on GPs' and patients' characteristics will also be collected. (2) How many and which medication alerts were dealt with? (3) Was the intervention implemented as intended? (4) On what days did GPs use the intervention tool? METHODS: The process evaluation is part of a stepped-wedge cluster-randomized controlled trial. Characteristics of practices, GPs and patients using the CDSS will be compared with the non-participating population. CDSS log data will be analyzed to evaluate how the number of medication alerts changed between baseline and 2 months later, and to identify the kind of alerts that were dealt with. Comparison of enrolled patients on weekdays versus weekends will shed light on GPs' use of the CDSS in the absence or presence of patients. Outcomes will be presented using descriptive statistics, and significance tests will be used to identify associations between them. We will conduct subgroup analyses, including time effects to account for software improvements. DISCUSSION: This study protocol is the basis for conducting analyses of the quantitative process evaluation. By providing insight into how GPs conduct medication reviews, the evaluation will provide context to the trial results and support their interpretation. The evaluation relies on the proper documentation by GPs, potentially limiting its explanatory power.

[Digital Health Applications: A Qualitative Study of Approaches to Improve Access to Statutory Health Insurance]. / Lösungsansätze für den Zugang digitaler Gesundheitsanwendungen zur Gesetzlichen Krankenversicherung: eine qualitative Studie.

BACKGROUND: There is a lack of integration of appropriate digital health applications (DiGA) into the first healthcare market in Germany. In order to enable a valid and reliable use of previously examined digital health products, their implementation into services of the statutory health insurance (SHI) is necessary. The aim of this study was the development of strategies to modify and improve access of DiGA to SHI reimbursement. The recently introduced Digitale-Versorgung-Gesetz (DVG) is an initial step in this direction. METHODS: Using a qualitative approach, focus group interviews were conducted with key stakeholders of existing access paths. Previously elaborated problem-solving approaches were discussed. The approaches ranged between adapting existing structures and implementing an original digital pathway. Subsequently, a comparison of the project results and legislative provision of the DVG was carried out. RESULTS: The proposed approaches were discussed heterogeneously and varied depending on the position of the participants. The implementation of an Advisory Council had a greater consensus than the introduction of a digital-specific pathway. Also individual measures like administrative support for generating the necessary evidence was considered as positive and beneficial. However, a deviation from the current evidence standards should be avoided. Furthermore, the legitimacy and time expenditure for the digital-specific pathway was called into doubt. CONCLUSIONS: In principle, a better focus on existing structures on digital health applications can be endorsed. For a short-term use of DiGA potentials, adaptions of existing structures are preferable. The DVG legislation, although conforming to the project results only to some degree, can be considered as a first step. An amendment, in particular from the viewpoint of diagnostic or therapeutic DiGA, appears to be necessary.

Healthcare Costs and Resource Use Associated With Cervical Intraepithelial Neoplasia and Cervical Conization: A Retrospective Study of German Statutory Health Insurance Claims Data.

Background: Cervical intraepithelial neoplasia (CIN) can be a consequence of human papillomavirus (HPV) infection. High-grade CIN (CIN2/CIN3) may develop from persistent HPV infection and progress to cervical cancer if left untreated. Management of CIN includes conservative surveillance or ablation and excision by conization. Internationally, CIN and its treatment generate a considerable economic burden, but no current data regarding costs and resource use from the perspective of the German statutory health insurance exist. Objectives: The aim of this study was to explore the health economic burden in women with CIN diagnoses who either underwent cervical conization or were managed conservatively. Methods: We conducted a retrospective claims data analysis using the InGef Research Database from 2013 to 2018. Healthcare costs and resource utilization in a 24-month observation period (1:1:1 matching) were compared in 18- to 45-year-old women with CIN (1-3) who underwent a conization procedure (study cohort 1) and in women with CIN (1-3) who did not undergo conization (study cohort 2) to women with neither CIN nor conization (control group). Results: For each group, 2749 women were identified. Mean total healthcare costs after 24 months were higher in study cohort 1 (€4446, P<.01) and study cohort 2 (€3754, P=.09) compared with the control group (€3426). Comparing study cohort 1 and 2 to controls, mean differences were highest in age groups 41-45 years (cohort 1: €5115 vs €3354, P<.01; cohort 2: €4152 vs €3354, P=.14). Significantly more women were hospitalized at least once in study cohort 1 (57.46%, P<.01) and study cohort 2 (38.74%, P<.01) compared with the control group (31.14%). Frequency of outpatient physician visits was significantly higher in both study cohorts (43.23 visits, P<.01 and 38.60 visits, P<.01) compared with the control group (32.07 visits). Conclusion: Our results revealed 30% and 10% increased total healthcare costs in women with CIN undergoing invasive treatment (study cohort 1) and conservative management (study cohort 2), respectively, compared with a control group of women with no CIN in a 2-year follow-up period.

Reduction of Potentially Inappropriate Medication in the Elderly.

BACKGROUND: Medications with an unfavorable risk-benefit profile in the elderly, and for which there are safer alternatives, are designated as potentially inappropriate medications (PIM). The RIME trial (Reduction of Potentially Inappropriate Medication in the Elderly) was based on PRISCUS, a list of PIM that was developed in 2010 for the German pharmaceuticals market. In this trial, it was studied whether special training and the PRISCUS card could lessen PIM and undesired drug-drug interactions (DDI) among elderly patients in primary care. METHODS: A three-armed, cluster-randomized, controlled trial was carried out in two regions of Germany. 137 primary care practices were randomized in equal numbers to one of two intervention groups-in which either the primary care physicians alone or the entire practice team received special training-or to a control group with general instructions about medication. The primary endpoint was the percentage of patients with at least one PIM or DDI (PIM/DDI) per practice. The primary hypothesis was that at 1 year this endpoint would be more effectively lowered in the intervention groups compared to the control group. RESULTS: Among 1138 patients regularly taking more than five drugs, 453 (39.8%) had at least one PIM/DDI at the beginning of the trial. The percent - ages of PIM/DDI at the beginning of the trial and 1 year later were 43.0% and 41.3% in the intervention groups and 37.0% and 37.6% in the control group. The estimated intervention effect of any intervention (69 practices) versus control (68 practices) was 2.3% (p = 0.36), while that of team training (35 practices) versus physician training (34 practices) was 4.3% (p = 0.22). CONCLUSION: The interventions in the RIME trial did not significantly lower the percentage of patients with PIM or DDI.

Patient-Reported Financial Distress in Cancer: A Systematic Review of Risk Factors in Universal Healthcare Systems.

Financial toxicity is a side effect of cancer that results from the perceived financial distress an individual may experience in the course of the disease. The purpose of this paper is to analyse underlying factors related to subjective financial distress in high-income countries with universal healthcare coverage. A systematic literature review was conducted to identify qualitative and quantitative studies of cancer patient-reported subjective financial distress by performing a search in the databases of PubMed, PsycINFO and CINAHL up to December 2020. A qualitative synthesis was performed linking the time-dependent occurrence of risk factors to derived categories of risk factors. Out of 4321 identified records, 30 quantitative and 16 qualitative studies were eligible. Classification of risk factors resulted in eight categories with a total of 34 subcategories. Subjective financial distress is primarily determined by pre-diagnosis sociodemographic- factors as well as financial and work factors that might change during the course of the disease. The design of healthcare and social security systems shapes the country-specific degree of subjective financial distress. Further research should focus on evolving multidisciplinary intervention schemes and multidimensional instruments for subjective financial distress to account for identified risk factors in universal healthcare systems more precisely.

Effectiveness of the application of an electronic medication management support system in patients with polypharmacy in general practice: a study protocol of cluster-randomised controlled trial (AdAM).

INTRODUCTION: Clinically complex patients often require multiple medications. Polypharmacy is associated with inappropriate prescriptions, which may lead to negative outcomes. Few effective tools are available to help physicians optimise patient medication. This study assesses whether an electronic medication management support system (eMMa) reduces hospitalisation and mortality and improves prescription quality/safety in patients with polypharmacy. METHODS AND ANALYSIS: Planned design: pragmatic, parallel cluster-randomised controlled trial; general practices as randomisation unit; patients as analysis unit. As practice recruitment was poor, we included additional data to our primary endpoint analysis for practices and quarters from October 2017 to March 2021. Since randomisation was performed in waves, final study design corresponds to a stepped-wedge design with open cohort and step-length of one quarter. SCOPE: general practices, Westphalia-Lippe (Germany), caring for BARMER health fund-covered patients. POPULATION: patients (≥18 years) with polypharmacy (≥5 prescriptions). SAMPLE SIZE: initially, 32 patients from each of 539 practices were required for each study arm (17 200 patients/arm), but only 688 practices were randomised after 2 years of recruitment. Design change ensures that 80% power is nonetheless achieved. INTERVENTION: complex intervention eMMa. FOLLOW-UP: at least five quarters/cluster (practice). recruitment: practices recruited/randomised at different times; after follow-up, control group practices may access eMMa. OUTCOMES: primary endpoint is all-cause mortality and hospitalisation; secondary endpoints are number of potentially inappropriate medications, cause-specific hospitalisation preceded by high-risk prescribing and medication underuse. STATISTICAL ANALYSIS: primary and secondary outcomes are measured quarterly at patient level. A generalised linear mixed-effect model and repeated patient measurements are used to consider patient clusters within practices. Time and intervention group are considered fixed factors; variation between practices and patients is fitted as random effects. Intention-to-treat principle is used to analyse primary and key secondary endpoints. ETHICS AND DISSEMINATION: Trial approved by Ethics Commission of North-Rhine Medical Association. Results will be disseminated through workshops, peer-reviewed publications, local and international conferences. TRIAL REGISTRATION: NCT03430336. ClinicalTrials.gov (https://clinicaltrials.gov/ct2/show/NCT03430336).

[Individual financial burden following a cancer diagnosis from the perspective of social services in Germany]. / Individuelle finanzielle Belastungen infolge einer Krebserkrankung aus der Perspektive von Sozialdiensten in Deutschland.

BACKGROUND: In addition to physical, psychological and social effects, economic effects and the associated financial burden of a cancer diagnosis may also gain in importance during prolonged disease progression. Counselling by social services is an important factor in coping with this burden. METHODS: People employed in social work in oncology were invited to participate in a survey. The survey comprises 16 items on the perception of financial burdens, changes in the relevance of the topic, risk factors and current counselling practice. RESULTS: 81% of the respondents reported that the financial burden arising from a cancer diagnosis is a relevant topic of consultation for at least half of the patients. For 55%, this topic has become more important in recent years, which is due to higher survival rates, an increased number of younger patients, and poorer social security and working conditions. DISCUSSION AND CONCLUSION: Despite comprehensive insurance coverage, the financial burden of cancer patients has also gained in importance in Germany and must be increasingly taken into account in everyday social service counselling. Due to numerous risk factors and complex reasons, further measures are required to enable the early identification of risk constellations and to improve the situation of those affected.

["Alternative study designs" for the evaluation of digital health applications - a real alternative?] / "Alternative Studiendesigns" zur Bewertung digitaler Gesundheitsanwendungen ­ eine echte Alternative?

INTRODUCTION: After the Digital Healthcare Act (Digitale-Versorgung-Gesetz, DVG) reformed digital health applications' (Digitale Gesundheitsanwendungen, DiGAs) access to German Statutory Health Insurance (SHI) reimbursement, the discussion concerning necessary evidence requirements has intensified. In the past, different "alternative study designs" have been proposed to replace randomized controlled trials (RCTs) in the DiGA efficacy and benefit assessments. The present paper examines the suitability of these alternative designs for informing SHI reimbursement decisions. METHODS: The four alternative study designs primarily discussed in the context of DiGA - "Continuous Evaluation of Evolving Behavioral Intervention Technologies" (CEEBIT), "Multiphase Optimization Strategy" (MOST), "Sequential Multiple Assignment Randomized Trial" (SMART) and "Micro-Randomized Trial" (MRT) - are characterized and compared on the basis of relevant primary and secondary sources. Subsequently, their suitability for effectiveness and benefit evaluation in the context of SHI reimbursement decisions is discussed. RESULTS: None of the study designs examined aims primarily at conclusively demonstrating efficacy and benefit. Three of the four designs (MOST, SMART, MRT) focus on the development and optimization of interventions. In order to reduce resource requirements, the approaches presented sometimes deviate considerably from the methodological approach in traditional RCTs. This is especially true for their applied statistical error tolerance and their underlying randomization logic. Three of the four concepts (MOST, SMART, MRT) therefore still require RCTs after the development phase in order to demonstrate the effectiveness and benefit of the optimized intervention. DISCUSSION: The methodological differences of the alternative study designs compared to classical RCTs are accompanied by serious potentials for bias and uncertainties with regard to the identified intervention effects. These may be acceptable in the context of intervention development, but do not appear to be appropriate for use in collective SHI reimbursement decisions. CONCLUSION: The alternative study designs presented cannot be regarded as a suitable RCT alternative for efficacy and benefit assessments. A pragmatic study design, which continues to meet high methodological standards, and better utilization of real-world data could, in the future, contribute to a compromise between the justified claims to sufficient certainty of results on the one hand and appropriate procedural effort on the other.

High-Expenditure Disease in the EU-28: Does Drug Spend Correspond to Clinical and Economic Burden in Oncology, Autoimmune Disease and Diabetes?

BACKGROUND: Drug costs are increasing in Europe, and there is a heightened need to reduce pressure on healthcare systems. In 2017, oncology, autoimmune disease, and diabetes featured as the three highest therapy areas for drug spend in the EU-28. However, the absolute 1-year drug spend growth for diabetes did not feature within the ten fastest growing therapy areas. OBJECTIVE: This study explores the association between drug spend and disease burden in oncology, autoimmune disease, and diabetes in the EU-28. METHODS: Oncology, autoimmune disease and diabetes therapeutic areas were investigated using four methodologies. Historical and forecasted drug spend was analysed using the IQVIA MIDAS® drug sales database. Clinical and economic burden was estimated from targeted literature reviews. Trend analyses compared changes in drug spend with clinical burden using the Global Burden of Disease tool as the epidemiological reference. Cost per quality-adjusted life-years (QALYs) from UK health technology assessments were compared to interpret the health economic value. RESULTS: Oncology had the highest historical drug spend and growth compared with autoimmune disease and diabetes. Total drug spend and growth in oncology is forecasted to exceed diabetes by twofold. Increasing oncology drug spend historically did not correspond with reductions in mortality and morbidity. Diabetes had the lowest drug spend and greatest QALY/€1000 spent benefit. CONCLUSION: This study indicates that drug spend may not correlate to clinical burden across diseases. Future research could stimulate debate on whether more equitable drug funding may improve disease management.

Application study of the EQ-5D-5L in oncology: linking self-reported quality of life of patients with advanced or metastatic colorectal cancer to clinical data from a German tumor registry.

BACKGROUND: The EQ-5D-5L questionnaire is used in oncology to generate health-related quality of life (HRQoL) weights and corresponding health states. The purpose was to explore the relationship between demographic and clinical characteristics and HRQoL among advanced or metastatic colorectal cancer (CRC) patients by linking clinical data of a German CRC registry to self-reported HRQoL measures from the EQ-5D-5L. METHODS: The study sample included patients with advanced or metastatic CRC currently recruited in the German Tumor Registry Colorectal Cancer. The EQ-5D-5L was administered once to patients who were at the start or at later stages of palliative treatment. Data on comorbidities, disease-specific health states, symptoms, and treatment status were drawn from the registry. Multivariate regression analyses were performed to explore the impact of patient and disease characteristics on HRQoL. RESULTS: In total, n = 433 questionnaires were included in the data analysis. Mean age of patients was 66.3 years and 61.2% were male. The mean EQ-5D-5L utility score was 0.82 and the mean EQ-5D-5L VAS score was 62.05. The regression analyses revealed that none of the demographic characteristics and few of the clinical characteristics, such as fatigue and pain, had a significant impact on the HRQoL. CONCLUSIONS: The study demonstrated a reduced HRQoL of patients with advanced or metastatic CRC when compared to the general population. The symptoms fatigue and pain negatively affected the HRQoL, whereas other characteristics such as age, gender, and comorbidities did not have a significant impact on HRQoL.

The patient-level effect of the cost of Cancer care - financial burden in German Cancer patients.

BACKGROUND: Financial toxicity of cancer has so far been discussed primarily in the US health care system and is associated with higher morbidity and mortality. In European health care systems, the socio-economic impact of cancer is poorly understood. This study investigates the financial burden and patient-reported outcomes of neuroendocrine (NET) or colorectal (CRC) cancer patients at a German Comprehensive Cancer Center. METHODS: This prospective cross-sectional study surveyed 247 advanced stage patients (n = 122 NET/n = 125 CRC) at the National Center for Tumor Diseases, in Germany about cancer-related out-of-pocket costs, income loss, distress, and quality of life. Multiple linear regression analysis was performed to demonstrate the effects of economic deterioration on patients' quality of life and distress. RESULTS: 81% (n = 199) of the patients reported out-of-pocket costs, and 37% (n = 92) income loss as a consequence of their disease. While monthly out-of-pocket costs did not exceed 200€ in 77% of affected patients, 24% of those with income losses reported losing more than 1.200€ per month. High financial loss relative to income was significantly associated with patients' reporting a worse quality of life (p < .05) and more distress (p < .05). CONCLUSIONS: Financial toxicity in third-party payer health care systems like Germany is caused rather by income loss than by co-payments. Distress and reduced quality of life due to financial problems seem to amplify the burden that already results from a cancer diagnosis and treatment. If confirmed at a broader scale, there is a need for targeted support measures at the individual and system level.

Burden of HPV related anogenital diseases in young women in Germany - an analysis of German statutory health insurance claims data from 2012 to 2017.

BACKGROUND: Most individuals are infected with human papillomavirus (HPV) at least once in their lifetime. Infections with low-risk types can cause genital warts, whereas high-risk types can cause malignant tumors. The aim of this study was to determine the burden of anogenital diseases potentially related to HPV in young women based on German statutory health insurance claims data. METHODS: We conducted a retrospective claims data analysis using the "Institute for Applied Health Research Berlin" (InGef) Research Database, containing claims data from approximately 4 million individuals. In the period from 2012 to 2017 all women born in1989-1992, who were continuously insured between the age of 23-25 years were identified. Using ICD-10-GM codes (verified diagnosis in the outpatient sector or primary or secondary diagnosis in the inpatient sector) the administrative prevalence (95% confidence interval) of genital warts (A63.0), anogenital diseases grade I (K62.8, N87.0, N89.0, N90.0), grade II (N87.1, N89.1, N90.1) and grade III (D01.3, D06.-, D06.0, D07.1, D07.2, N87.2, N89.2, N90.2) was calculated (women with diagnosis divided by all women). RESULTS: From 2012 to 2017, a total of 15,358 (birth cohort 1989), 16,027 (birth cohort 1990), 14,748 (birth cohort 1991) and 14,862 (birth cohort 1992) women at the age of 23-25 were identified. A decrease of the administrative prevalence was observed in genital warts (1.30% (1.12-1.49) birth cohort 1989 vs. 0.94% (0.79-1.10) birth cohort 1992) and anogenital diseases grade III (1.09% (0.93-1.26) birth cohort 1989 vs. 0.71% (0.58-0.86) birth cohort 1992). In anogenital diseases grade III, this trend was especially observed for severe cervical dysplasia (N87.2) (0.91% (0.76-1.07) birth cohort 1989 vs. 0.60% (0.48-0.74) birth cohort 1992). In contrast, anogenital diseases grade I (1.41% (1.23-1.61) birth cohort 1989 vs. 1.31% (1.14-1.51) birth cohort 1992) and grade II (0.61% (0.49-0.75) birth cohort 1989 vs. 0.52% (0.42-0.65) birth cohort 1992) remained stable. CONCLUSIONS: A decrease of the burden of anogenital disease potentially related to HPV was observed in the younger birth cohorts. This was observed especially for genital warts and anogenital diseases grade III. Further research to investigate this trend for the upcoming years in light of varying HPV vaccination coverage for newer birth cohorts is necessary.
