Homelessness and associated factors over a 13-year period among psychiatric in-patients in Berlin, Germany: routine data analysis.

BACKGROUND: Homeless patients in psychiatric hospitals are a scarcely studied and there is lack of knowledge about factors associated with homelessness and in-patient treatment. AIMS: To determine the change over time in the number of homeless psychiatric in-patients and to examine factors associated with homelessness. METHOD: Retrospective data analysis of 1205 selected electronic patient files on psychiatric in-patient treatment in a university psychiatric hospital in Berlin, Germany. The rate of patients experiencing homelessness over a 13-year period (2008-2021) and the sociodemographic and clinical factors associated with homelessness are analysed over time. RESULTS: Our study revealed a 15.1% increase in the rate of homeless psychiatric in-patients over the 13-year period. Of the whole sample, 69.3% people lived in secure private housing, 15.5% were homeless and 15.1.% were housed in sociotherapeutic facilities. Homelessness was significantly associated with being male (OR = 1.76 (95% CI 1.12-2.76), born outside of Germany (OR = 2.22, 95% CI 1.47-3.34), lack of out-patient treatment (OR = 5.19, 95% CI 3.35-7.63), psychotic disorders (OR = 2.46, 95% CI 1.16-5.18), reaction to severe stress (OR = 4.19, 95% CI 1.71-10.24), personality disorders (OR = 4.98, 95% CI 1.92-12.91), drug dependency (OR = 3.47, 95% CI 1.5-8.0) and alcohol dependency (OR = 3.57, 95% CI 1.67-7.62). CONCLUSIONS: The psychiatric care system is facing an increasing number of patients in precarious social situations. This should be considered in resource allocation planning in healthcare. Individual solutions for aftercare, along with supported housing, could counteract this trend.

Use of digital technologies by users of psychiatric inpatient services in Berlin, Germany: a cross-sectional patient survey.

Few studies and almost exclusively from the USA have recently investigated mobile phone and computer use among users of psychiatric services, which is of high relevance regarding the increasing development of digital health applications and services. OBJECTIVE, DESIGN AND SETTING: In a cross-sectional patient survey, we examined (a) rates and purposes of mobile phone, computer, internet and social media use, and (b) the role of social and clinical predictors on rates of utilisation among psychiatric inpatients in Berlin, Germany. PARTICIPANTS AND RESULTS: Descriptive analyses showed that among 496 participants, 84.9% owned a mobile phone and 59.3% a smartphone. Among 493 participants, 68.4% used a computer regularly. Multivariate logistic regression models revealed being homeless, diagnosis of a psychotic illness, being of older age and a lower level of education to be significant predictors for not owning a mobile phone, not using a computer regularly or having a social media account, respectively. CONCLUSIONS: Users of psychiatric services may have access to mobile phones and computers, although rates are lower than in the general population. However, key barriers that need to be addressed regarding the development of and engagement with digital health interventions are factors of social exclusion like marginalised housing as well as clinical aspects like psychotic illness.

Associations among navigational support and health care utilization and costs in patients with advanced cancer: An analysis based on administrative health insurance data.

BACKGROUND: Fragmented and complex healthcare systems make it difficult to provide continuity of care for patients with advanced cancer near the end of life. Nurse-based cross-sectoral navigation support has the potential to increase patients' quality of life. The objective of this paper was to evaluate associations between navigation support and health care utilization, and the associated costs of care. METHODS: The evaluation is based on claims data from 37 statutory health insurance funds. Non-randomized recruitment of the intervention group (IG) took place between 2018 and 2019 in four German hospitals. The comparison group (CG) was defined ex post. It comprises nonparticipating clients of the involved health insurance funds matched on age, gender, and diagnosis in a 1:4 ratio to the IG. Healthcare resource utilization was compared using incident rate ratios (IRRs) based on negative binomial regression models. Linear mixed models were performed to compare differences in lengths of hospital stays and costs between groups. RESULTS: A total of 717 patients were included (IG: 149, CG: 568). IG patients showed shorter average lengths of hospital stays (IG: 11 days [95% CI: 10, 13] vs. CG: 15 days [95% CI: 14, 16], p < 0.001). In the IG, 21% fewer medications were prescribed and there were on average 15% fewer outpatient doctor contacts per month. Average billed costs in the IG were 23% lower than in the CG (IG: 6754 EUR [95% CI: 5702, 8000] vs. CG: 8816 EUR [95% CI: 8153, 9533], p < 0.001). CONCLUSIONS: The intervention was associated with decreased costs mainly as a result of a non-intended navigation effect. The social care nurses had navigated patients within the hospital early, needs-oriented and effectively but interpreted their function less cross-sectorally. Linkage of hospital-based navigators with the outpatient care sector needs further exploration.

The Abdominal Pain Unit (APU). Study protocol of a standardized and structured care pathway for patients with atraumatic abdominal pain in the emergency department: A stepped wedged cluster randomized controlled trial.

This study aims to improve emergency department (ED) care for patients suffering from atraumatic abdominal pain. An application-supported pathway for the ED will be implemented, which supports quick, evidence-based, and standardized diagnosis and treatment steps for patients with atraumatic abdominal pain at the ED. A mixed-methods multicentre cluster randomized controlled stepped wedge trial design will be applied. A total of 10 hospitals with EDs (expected n = 2.000 atraumatic abdominal pain patients) will consecutively (every 4 months) be randomized to apply the intervention. Inclusion criteria for patients are a minimum age of 18 years, suffering from atraumatic abdominal pain and being insured with a German statutory health insurance. Primary outcomes: acute pain score at time of discharge from ED, duration of treatment at the ED, patient-reported satisfaction. Secondary endpoints include patient safety and quality of care parameters, process evaluation parameters, and costs and cost-effectiveness parameters. Quantitative data will be gathered from patient-surveys, clinical records, and routine data from hospital information systems as well as from a participating German statutory health insurance. Descriptive and analytic statistical analysis will be performed to provide summaries and associations for primary patient-reported outcomes, process measures, quality measures, and costs. Qualitative data collection consists of participatory patient observations and semi-structured expert interviews, which will be inductively analysed. Findings will be disseminated in publications in peer-reviewed journals, on conferences, as well as via a project website. To ensure data protection, appropriate technical and organisational measures will be taken. Trial registration: DRKS00021052.

Development of a patient-oriented navigation model for patients with lung cancer and stroke in Germany.

BACKGROUND: The concept of patient navigation was first established in the USA to support vulnerable patient groups in receiving timely and comprehensive access to cancer care. It has recently gained increasing interest in Germany to support patients with chronic diseases in a fragmented healthcare system. The aim of this paper is to present the development of such a model adapted to the German context based on the results of mixed-methods studies investigating the need for and barriers to patient-oriented care. METHODS: In a process adapted from Delphi rounds, we conducted regular structured workshops with investigators of the project to discuss results of their studies and identify content and structure of the model based on the data. Workshop discussions were structured along seven core components of a navigation model including target patient groups, navigator tasks, occupational background and education of navigators, and patient-navigator interaction mode. RESULTS: Using an approach based on empirical data of current care practices with special focus on patients' perspectives, we developed a patient-oriented navigation model for patients who have experienced stroke and lung cancer in the German healthcare context. Patients without personal social support were viewed as struggling most with the healthcare system, as well as multimorbid and elderly patients. Navigators should serve as a longer-term contact person with a flexible contact mode and timing based on the individual situation and preferences of patients. Navigator tasks include the provision of administrative and organizational support as well as referral and guidance to available resources and beneficial health programs with special forms of knowledge. Implementation of the navigator should be flexibly located to ensure a reliable outreach to vulnerable patients for first contact in settings like specialized in-patient and out-patient settings, while navigation itself focuses on care coordination in the out-patient setting. CONCLUSION: Flexibility of navigator tasks needed to be a core characteristic of a navigation model to be perceived as supportive from patients' perspectives. In a subsequent feasibility study, an intervention based on the model will be evaluated according to its acceptance, demand, and practicality.

Identifying and handling unbalanced baseline characteristics in a non-randomized, controlled, multicenter social care nurse intervention study for patients in advanced stages of cancer.

PURPOSE: Given the psychosocial burdens patients in advanced stages of cancer face, innovative care concepts are needed. At the same time, such vulnerable patient groups are difficult to reach for participation in intervention studies and randomized patient inclusion may not be feasible. This article aims to identify systematic biases respectively selection effects occurring during the recruitment phase and to discuss their potential causes based on a non-randomized, multicenter intervention study with patients in advanced stages of cancer. METHODS: Patients diagnosed with at least one of 16 predefined cancers were recruited at four hospitals in three German cities. The effect of social care nurses' continuous involvement in acute oncology wards was measured by health-related quality of life (EORTC QLQ-C30), information and participation preferences, decisional conflicts, doctor-patient communication, health literacy and symptom perception. Absolute standardized mean difference was calculated as a standardized effect size to test baseline characteristics balance between the intervention and control groups. RESULTS: The study enrolled 362 patients, 150 in the intervention and 212 in the control group. Except for gender, both groups differed in relevant socio-demographic characteristics, e.g. regarding age and educational background. With respect to the distribution of diagnoses, the intervention group showed a higher symptom burden than the control group. Moreover, the control group reported better quality of life at baseline compared to the intervention group (52.6 points (SD 21.7); 47.8 points (SD 22.0), ASMD = 0.218, p = 0.044). CONCLUSION: Overall, the intervention group showed more social and health vulnerability than the control group. Among other factors, the wide range of diagnoses included and structural variation between the recruiting clinics increased the risk for bias. We recommend a close, continuous monitoring of relevant social and health-related characteristics during the recruitment phase as well as the use of appropriate statistical analysis strategies for adjustment, such as propensity score methods.

Guideline adherence in speech and language therapy in stroke aftercare. A health insurance claims data analysis.

BACKGROUND: Impairments to comprehension and production of speech (aphasia, dysarthria) and swallowing disorders (dysphagia) are common sequelae of stroke, reducing patients' quality of life and social participation. Treatment oriented on evidence-based guidelines seems likely to improve outcomes. Currently, little is known about guideline adherence in stroke aftercare for the above-mentioned sequelae. This study aims to analyse guideline adherence in the treatment of aphasia, dysarthria and dysphagia after stroke, based on suitable test parameters, and to determine factors that influence the implementation of recommended therapies. METHODS: Six test parameters were defined, based on systematic study of guidelines for the treatment of speech impairments and swallowing disorders (e.g. comprehensive diagnostics, early initiation and continuity). Guideline adherence in treatment was tested using claims data from four statutory health insurance companies. Multivariate logistic and linear regression analyses were performed in order to test the outcomes. RESULTS: 4,486 stroke patients who were diagnosed with specific disorders or received speech therapy were included in the study. The median age was 78 years; the proportion of women was 55.9%. Within the first year after the stroke, 90.3% of patients were diagnosed with speech impairments and swallowing disorders. Overall, 44.1% of patients received outpatient speech and language therapy aftercare. Women were less frequently diagnosed with specific disorders (OR 0.70 [95%CI:0.55/0.88], p = 0.003) and less frequently received longer therapy sessions (OR 0.64 [95%CI:0.43/0.94], p = 0.022). Older age and longer hospitalization duration increased the likelihood of guideline recommendations being implemented and of earlier initiation of stroke aftercare measures. CONCLUSIONS: Our observations indicate deficits in the implementation of guideline recommendations in stroke aftercare. At the same time, they underscore the need for regular monitoring of implementation measures in stroke aftercare to address group-based disparities in care.

Characteristics and patient-reported outcomes associated with dropout in severely affected oncological patients: an exploratory study.

BACKGROUND: Patient-reported outcome measures (PROMs) are commonly-used surrogates for clinical outcomes in cancer research. When researching severe diseases such as cancer, it is difficult to avoid the problem of incomplete questionnaires from drop-outs or missing data from patients who pass away during the observation period. The aim of this exploratory study was to explore patient characteristics and the patient-reported outcomes associated with the time-to-dropout. METHODS: In an Oncological Social Care Project (OSCAR) study, the condition of the participants was assessed four times within 12 months (t0: baseline, t1: 3 months, t2: 6 months, and t3: 12 months) by validated PROMs. We performed competing-risk regressions based on Fine and Gray's proportional sub-distribution hazards model for exploring factors associated with time-to-dropout. Death was considered a competing risk. RESULTS: Three hundred sixty-two participants were analyzed in the study. 193 (53.3%) completed a follow-up after 12 months, 67 (18.5%) patients dropped out, and 102 patients (28.2%) died during the study period. Poor subjective social support was related to a higher risk of drop-out (SHR = 2.10; 95%CI: 1.01-4.35). Lower values in health-related quality of life were related to drop-out and death. The sub-scales global health status/QoL, role functioning, physical functioning, and fatigue symptom in the EORTC QLQ-C30 were key characteristics of early drop-out. CONCLUSION: Severely affected cancer patients with poor social support and poor quality of life seem more likely to drop out of studies than patients with higher levels of social support and a better quality of life. This should be considered when planning studies to assess advanced cancer patients. Methods of close continued monitoring should be actively used when patient experiences a substantial deterioration in their health-related quality of life and symptoms during the study. Results for such studies have to be interpreted with caution in light of specific drop-out mechanisms.

A retrospective analysis of the health and social situation of homeless people in Berlin: study protocol.

BACKGROUND: Homelessness is often described as both a driver and a consequence of poor health, social exclusion and economic marginalisation. The present protocol provides a detailed description of the study Examining the health situation of homeless people in Berlin: a retrospective analysis of data from the health centre for the homeless of the Jenny De la Torre Foundation from 2006 to 2020 (GIG study). The primary objective of the GIG study is to describe and analyse the social and health situation of homeless people in Berlin. METHODS: A retrospective secondary data analysis of an anonymous full census of medical records for the years 2006 until 2020 from a health centre for homeless people will be carried out. The main outcome is the description and analysis of the social and health situation of homeless people in Berlin. Total and cross-sectional sample characteristics will be presented in a descriptive analysis using Chi-Square Test, Mann-Whitney-U-Test or independent t-Test as appropriate to test (sub) group differences. Further, outcomes will be analysed using finite mixture modelling in order to distinguish different types of social and health conditions. Latent variable regressions will be applied in order to identify sociodemographic and disease-related factors associated with decreasing health conditions. DISCUSSION: Given the high number of homeless individuals in Germany, it is of great importance to examine their social and health situation in order to gain a better understanding of challenges and needs of homeless people and work on new approaches and solutions to effectively address these. TRAIL REGISTRATION: The study was prospectively registered with the German Clinical Trials Register (trial registration number: DRKS00021172 ). Registered 26 June 2020.

Quality of life after stroke rehabilitation discharge: a 12-month longitudinal study.

PURPOSE: To analyse trends in quality of life (QoL) development among older stroke patients within the first year after rehabilitation discharge, and to investigate the impact of including proxy interviews in research and practice. METHODS: A prospective cohort study with follow-up at 3, 6, and 12 months with 411 patients and proxy respondents was conducted. The EUROHIS-QOL 8-item index was used to assess QoL. By performing descriptive analyses, QoL development over time was compared among subgroups. Linear mixed models were calculated to estimate mean changes from baseline to 12-month follow-up. The effects of patient characteristics and time on QoL were investigated using comprehensive mixed models. RESULTS: One year after rehabilitation discharge, the majority of patients had neither maintained nor regained their initial QoL. Proxy respondents reported significantly lower QoL (22.6-29.5 points, p < 0.001). Characteristics associated with lower QoL were stroke severity, depression, and pain. Having a small social network was negatively associated with QoL (-1.66 points, 95%CI: -2.84/-0.48, p = 0.006). CONCLUSIONS: Quality of life scores reported at the time of rehabilitation discharge are often not lasting. Including severely impaired patients via proxies reduces the risk of overestimating QoL outcomes. Outpatient's characteristics should be taken into account when planning therapy strategies to maintain previously achieved health goals. Regular re-assessments are required.Implications for rehabilitationThere should be an awareness that improvements in quality of life (QoL) achieved during rehabilitation are not sustainable.Regularly re-assessing pain status, psychological burden, and social network size could help clinicians to determine treatment strategies for maintaining and improving rehabilitation achievements.Conducting proxy interviews is required to assess disease burden of patients with severe stroke (e.g., non-linguistic patients).

[Somatic diseases of homeless people in Germany. A narrative literature review for the years 2009-2019]. / Somatische Erkrankungen Wohnungsloser in Deutschland. Ein narratives Literaturreview der Jahre 2009­2019.

BACKGROUND: According to estimates, between 337,000 and 650,000 people in Germany live without a permanent residence. They are highly deprived in terms of health. Studies on the health situation are rare and methodologically heterogeneous. Previous reviews have focused on mental illness. OBJECTIVES: The aim of this paper is to provide an overview of current research on somatic diseases of homeless people in Germany. METHODS: Based on a systematic literature review for the years 2009-2019, the methodological approaches, sample access, recruitment, and health aspects reported in the studies are compared. RESULTS: By means of a systematic literature search, eight peer-reviewed journal articles were identified. Often the term "homelessness" was not operationalised. The average age of homeless participants was between 40.9 years and 67 years, and the proportion of women was between 0 and 35.3%. Frequently the sample was taken from accommodation and medical services for homeless people. One recruitment strategy was "respondent-driven sampling" in conjunction with incentives. The respondents most frequently reported cardiovascular diseases (17%-37.2%), musculoskeletal diseases (≥20%), and respiratory diseases (7%-24%). Depending on the recruitment site, infectious diseases were common (tuberculosis, hepatitis B and C). CONCLUSION: Somatic health studies of homeless people are often selective. Older men with lower educational backgrounds living in large German cities appear to be overrepresented, and there is no uniform use of the term "homelessness." Compared with representative population data for Germany, increased risks of somatic illness were observed; cohort characteristics can explain these to a limited extent. Biographical and intersectional approaches are needed to capture multiple and cumulative exposure situations in homelessness.

Improving quality of life in cancer patients through higher participation and health literacy: study protocol for evaluating the oncological social care project (OSCAR).

BACKGROUND: Cancer patients experience psychological and social distress due to their medical treatment and social issues. However, continuous and specialized social support is still lacking. In Germany, a group of company health insurance funds has developed an approach to support cancer patients with monthly structured interviews conducted by specially trained Social Care Nurses. The nurses will identify patient needs in order to provide help with medical, personal, and social matters. One aim of the scientific evaluation is to analyze the effect of the consultations on various patient-reported outcomes, especially quality of life. The evaluation concept will be described in this study protocol. METHODS/DESIGN: The evaluation is a non-randomized, controlled, multi-center intervention study with a mixed-method design. It consists of three research modules which include primary data from questionnaires, and claims data from the health insurance funds. In Module 1, cancer patients will be recruited to form an intervention group (OSCAR, n = 150) and a control group (n = 200) in four study centers for a period of 1 year. One baseline and three follow-up questionnaires will be conducted to survey the patient-reported outcomes. Relevant secondary outcomes are health literacy, participation, and physician-patient communication. In Module 2, claims data will be used to analyze cost effects and thereby assess effectivity and hospitalization. Module 3 will involve a qualitative analysis of project diaries kept by the Social Care Nurses. The diaries will record the nurses' practical experiences and the benefits of deploying OSCAR across the German healthcare system. DISCUSSION: OSCAR is an innovative way of providing cancer patients with continuous support to improve their quality of life. The evaluation concept aims to assess the effects of the monthly consultations by the Social Care Nurses on the patients, and will use a mixed-method design. The results are important for assessing the transferability of OSCAR to the healthcare system as a whole. TRIAL REGISTRATION: German Clinical Trials Register (DRKS-ID: DRKS00013640 ).

Assessing acceptance of electric automated vehicles after exposure in a realistic traffic environment.

After years of hypothetical surveys and simulator studies, automated vehicles (AVs) are now being tested in realistic traffic environments adding validity to knowledge about their acceptance. We present data from a pilot test with participants (n = 125) after experiencing a ride in an electric AV on a large clinic area in Berlin, Germany. As a first contribution, we bridge the gap between missing definitions of key constructs, confusion about their operationalisations, and a rigorous test of their statistical properties and data structure by examining scales on acceptance, trust, perceived safety, intention to use, and-for the first time applied to AVs-the emotions amusement, fear, surprise, and boredom. Tests of reliability and normality were satisfying for almost all constructs (Cronbach's alphas ≥ .69; six of eight scales normally distributed). The vehicles were accepted (M = 1.22; SD = 0.70; range -2 to 2), trusted (M = 3.29; SD = 0.81; range 1 to 5), and perceived as safe (M = 3.29; SD = 1.03; range 1 to 5). However, factor analyses did not reflect the hypothesised data structure, and validity concerns question the suitability of some constructs for attitude assessment of electric AVs. Our open item for comments added valuable insights in qualitative aspects of user attitudes towards electric AVs regarding driving style, technical features, and (unsettling) audio-visual feedback. We thus argue for broader conceptualisations of key constructs based on interdisciplinary exchange and multi-methodical study designs.

[Quality of German-Language Guidelines for Post-Stroke Rehabilitation of Aphasia and Dysarthria - Results of a Systematic Review and of an International Comparison]. / Deutschsprachige Leitlinien für die Aphasie- und Dysarthriebehandlung nach Schlaganfall.

AIM: Evaluation of German-language guidelines for aphasia and dysarthria rehabilitation, and comparison with international guidelines. METHODS: The quality of the 6 included guidelines, as found through a comprehensive literature search, was sytematically evaluated using AGREE II. Quality ratings were compared to the results of a systematic review of 19 English-language guidelines. RESULTS: The quality of German-language guidelines was heterogeneous. In 2 out of 6 evaluation domains and in the overall assessment, no German-language guideline reached the cut-off of 66,67% for good guideline quality. Apart from the domain Editorial Independence, results remained behind those of the international reference guidelines. CONCLUSION: In some cases, quality can be improved by simple means. It is more resource-intensive, but crucial to document search strategies and how evidence was used in guideline development. A harmonization of the German-language guidelines seems desirable.

A study of energy absorption rate in a quantum dot and metallic nanosphere hybrid system.

We have studied energy absorption rate in a quantum dot-metallic nanosphere system embedded on a dielectric substrate. We applied a control field to induce dipole moments in the quantum dot and the metal nanosphere, and monitored the energy absorption using a probe field. These external fields induce dipole moments in the metal nanosphere and the quantum dot, and these two structures interact with one another via the dipole-dipole interaction. The density matrix method was used to evaluate the absorption, indicating that it can be shifted by moving the metal nanosphere close to the quantum dot. Also, absorption efficiency can either be quenched or enhanced by the addition of a metal nanosphere. This hybrid system can be used to create ultrafast switching and sensing nanodevices.
