Asking the generalist - evaluation of a General Practice rounding and consult service.

BACKGROUND: Vascular surgery patients admitted to the hospital are often multimorbid. In case of questions regarding chronic medical problems different specialties are consulted, which leads to a high number of treating physicians and possibly contradicting recommendations. The General Practitioner´s (GP) view could minimize this problem. However, it is unknown for which medical problems a GP would be consulted and if regular GP-involvement during rounds would be considered helpful by the specialists. The aim of this study was to establish and describe a General Practice rounding service (GP-RS), to evaluate if the GP-RS is doable in a tertiary care hospital and beneficial to the specialists and to explore GP-consult indications. METHODS: The GP-RS was established as a pilot project. Between June-December 2020, a board-certified GP from the Department of General Practice and Primary Care, University Medical Center Hamburg-Eppendorf (UKE) joined the vascular surgery team (UKE) once-weekly on rounds. The project was evaluated using a multi-methods approach: semi-structured qualitative interviews were conducted with vascular surgery physicians that had either participated in the GP-RS (G1), had not participated (G2), other specialists usually conducting consults on the vascular surgery floor (G3) and with the involved GP (G4). Interviews were analyzed using Kuckartz' qualitative content analysis. In addition, two sets of quantitative data were descriptively analyzed focusing on the reasons for a GP-consult: one set from the GP-RS and one from an established, conventional "as needed" GP-consult service. RESULTS: 15 interviews were conducted. Physicians perceived the GP-RS as beneficial, especially for surgical patients (G1-3). Optimizing medication, avoiding unnecessary consults and a learning effect for physicians in training (G1-4) were named as other benefits. Critical voices saw an increased workload through the GP-RS (G1, G3) and some consult requests as too specific for a GP (G1-3). Based on data from 367 vascular surgery patients and 80 conventional GP-consults, the most common reasons for a GP-consult were cardiovascular diseases including hypertension and diabetes. CONCLUSIONS: A GP-RS is doable in a tertiary care hospital. Studies of GP co-management model with closer follow ups would be needed to objectively improve patient care and reduce the overall number of consults. TRIAL REGISTRATION: Not applicable.

Effects of Two COVID-19 Lockdowns on HbA1c Levels in Patients with Type 1 Diabetes and Associations with Digital Treatment, Health Literacy, and Diabetes Self-Management: A Multicenter, Observational Cohort Study Over 3 Years.

INTRODUCTION: Short-term studies reported improved glycemic control and a decrease in eHbA1c (estimated hemoglobin A1c) in patients with type 1 diabetes during COVID-19 lockdown, but long-term changes are unknown. Therefore, the main objectives are to (1) analyze whether laboratory-measured HbA1c changed during and after two lockdowns and (2) investigate potential variables influencing HbA1c change. METHODS: In this cohort study, 291 adults with type 1 diabetes were followed over 3 years including the prepandemic phase and two lockdowns. The data from medical records and validated questionnaires assessing health literacy (HLS-EU-Q16), diabetes self-management (DSMQ-R27), general self-efficacy (GSE), and social support (F-SOZU-K14) were used to analyze associations with HbA1c levels (N = 2370) by performing multivariable linear regressions. RESULTS: The median age was 54 (38-63) years and 159 (54.6%) were male. All phases of the COVID-19 pandemic were associated with a significant increase in laboratory-measured HbA1c levels in percent (e.g., during first lockdown ß = 0.23, 95% confidence interval (CI) 0.07-0.39, p = 0.005; during the second lockdown, ß = 0.27, 95% CI 0.15-0.38, p < 0.001). HbA1c change during lockdowns was significantly affected by the number of checkups (ß = -0.03, 95% CI -0.05 to -0.01, p = 0.010), the value of HbA1c at previous observation (ß = 0.33, 95% CI 0.29-0.36, p < 0.001), educational level (secondary versus tertiary: ß = 0.22, 95% CI 0.06-0.38, p = 0.008; primary versus tertiary: ß = 0.31, 95% CI 0.10-0.52, p = 0.004), health literacy score (for each point: ß = -0.03, 95% CI -0.05 to - 0.002, p = 0.034), and diabetes self-management score (for each point: ß = -0.03, 95% CI -0.04 to -0.02, p < 0.001). The use of continuous glucose monitoring or insulin pump had no effect on HbA1c change. CONCLUSIONS: Lockdowns can lead to worsening glycemic control in patients with type 1 diabetes. Particularly patients with few check-ups, poor blood glucose values, deficits in diabetes self-management, low health literacy, and a low level of education seem to be at greater risk of worsening glycemic control during lockdowns and, therefore, require special medical care, e.g., through telemedicine.

Clinical effectiveness of patient-targeted feedback following depression screening in general practice (GET.FEEDBACK.GP): an investigator-initiated, prospective, multicentre, three-arm, observer-blinded, randomised controlled trial in Germany.

BACKGROUND: Screening for depression in primary care alone is not sufficient to improve clinical outcomes. However, targeted feedback of the screening results to patients might result in beneficial effects. The GET.FEEDBACK.GP trial investigated whether targeted feedback of the depression screening result to patients, in addition to feedback to general practitioners (GPs), leads to greater reductions in depression severity than GP feedback alone or no feedback. METHODS: The GET.FEEDBACK.GP trial was an investigator-initiated, multicentre, three-arm, observer-blinded, randomised controlled trial. Depression screening was conducted electronically using the Patient Health Questionnaire-9 (PHQ-9) in 64 GP practices across five regions in Germany while patients were waiting to see their GP. Currently undiagnosed patients (aged ≥18 years) who screened positive for depression (PHQ-9 score ≥10), were proficient in the German language, and had a personal consultation with a GP were randomly assigned (1:1:1) into a group that received no feedback on their depression screening result, a group in which only the GP received feedback, or a group in which both GP and patient received feedback. Randomisation was stratified by treating GP and PHQ-9 depression severity. Trial staff were masked to patient enrolment and study group allocation and GPs were masked to the feedback recieved by the patient. Written feedback, including the screening result and information on depression, was provided to the relevant groups before the consultation. The primary outcome was PHQ-9-measured depression severity at 6 months after randomisation. An intention-to-treat analysis was conducted for patients who had at least one follow-up visit. This study is registered at ClinicalTrials.gov (NCT03988985) and is complete. FINDINGS: Between July 17, 2019, and Jan 31, 2022, 25 279 patients were approached for eligibility screening, 17 150 were excluded, and 8129 patients completed screening, of whom 1030 (12·7%) screened positive for depression. 344 patients were randomly assigned to receive no feedback, 344 were assigned to receive GP-targeted feedback, and 339 were assigned to receive GP-targeted plus patient-targeted feedback. 252 (73%) patients in the no feedback group, 252 (73%) in the GP-targeted feedback group, and 256 (76%) in the GP-targeted and patient-targeted feedback group were included in the analysis of the primary outcome at 6 months, which reflected a follow-up rate of 74%. Gender was reported as female by 637 (62·1%) of 1025 participants, male by 384 (37·5%), and diverse by four (0·4%). 169 (16%) of 1026 patients with available migration data had a migration background. Mean age was 39·5 years (SD 15·2). PHQ-9 scores improved for each group between baseline and 6 months by -4·15 (95% CI -4·99 to -3·30) in the no feedback group, -4·19 (-5·04 to -3·33) in the GP feedback group, and -4·91 (-5·76 to -4·07) in the GP plus patient feedback group, with no significant difference between the three groups (global p=0·13). The difference in PHQ-9 scores when comparing the GP plus patient feedback group with the no feedback group was -0·77 (-1·60 to 0·07, d=-0·16) and when comparing with the GP-only feedback group was -0·73 (-1·56 to 0·11, d=-0·15). No increase in suicidality was observed as an adverse event in either group. INTERPRETATION: Providing targeted feedback to patients and GPs after depression screening does not significantly reduce depression severity compared with GP feedback alone or no feedback. Further research is required to investigate the potential specific effectiveness of depression screening with systematic feedback for selected subgroups. FUNDING: German Innovation Fund.

Interprofessional collaboration in the home care setting: perspectives of people receiving home care, relatives, nurses, general practitioners, and therapists-results of a qualitative analysis.

BACKGROUND: About one million people in need of home care in Germany are assisted by 15,400 home care services. Home healthcare is mostly a complex endeavour because interprofessional collaboration is often challenging. This might negatively impact patient safety. The project interprof HOME aims to develop an interprofessional person-centred care concept for people receiving home care in a multistep approach. In one of the work packages we explored how people receiving home care, relatives, nurses, general practitioners, and therapists (physiotherapists, occupational therapists, and speech therapists) perceive collaboration in this setting. METHODS: Semi-structured interviews were conducted with 20 people receiving home care and with 21 relatives. Additionally, we worked with nine monoprofessional focus groups involving nurses of home care services (n = 17), general practitioners (n = 14), and therapists (n = 21). The data were analysed by content analysis. RESULTS: Three main categories evolved: "perception of interprofessional collaboration", "means of communication", and "barriers and facilitators". People receiving home care and relatives often perceive little to no interprofessional collaboration and take over a significant part of the organisational coordination and information exchange. Interprofessional collaboration in steady care situations does exist at times and mostly occurs in coordination tasks. Contact and information exchange are rare, however, interprofessional personal encounters are sporadic, and fixed agreements and permanent contact persons are not standard. These trends increase with the complexity of the healthcare situation. Joint collaborations are often perceived as highly beneficial. Means of communications such as telephone, fax, or e-mail are used differently and are often considered tedious and time-consuming. No interprofessional formal written or electronic documentation system exists. Personal acquaintance and mutual trust are perceived as being beneficial, while a lack of mutual availability, limited time, and inadequate compensation hinder interprofessional collaboration. CONCLUSIONS: Interprofessional collaboration in home care occurs irregularly, and coordination often remains with people receiving home care or relatives. While this individual care set-up may work sufficiently well in low complex care situations, it becomes vulnerable to disruptions with increasing complexity. Close interactions, joint collaboration, and fixed means of communication might improve healthcare at home. The findings were integrated into the development of the person-centred interprofessional care concept interprof HOME. TRIAL REGISTRATION: This study is registered on the International Clinical Trails registry platform ClinicalTrials.gov as NCT05149937 on 03/11/2021.

[Intended utilization of health care services in cases of mental illnesses with varying urgency]. / Intendierte Inanspruchnahme von Versorgungsangeboten bei psychischen Erkrankungen mit unterschiedlicher Dringlichkeit.

OBJECTIVE: To investigate variations in intended utilization in cases of an acute psychotic episode, an alcohol related or depressive disorder depending on different case characteristics. METHODS: A telephone survey with case vignettes was conducted (N=1,200). Vignettes varied in terms of urgency of symptoms, daytime, sex of the afflicted person and age/mental disorder. The respondents were asked to indicate whom they would contact first in the described case. RESULTS: Outpatient physicians were named most frequently as the first point of contact (61.1%) while only 6.5% of the respondents named emergency medicine including the medical on call service (8.1% in high urgency cases, i. e. emergencies that did not tolerate any delay). Intended utilization varied by urgency and age/mental illness. CONCLUSION: More Information about the need to seek medical help immediately in cases of mental illnesses with high urgency should be provided.

Variations in the intended utilization of emergency care in case of gastrointestinal diseases.

Frequent utilization of emergency care and overcrowded emergency departments (EDs) are highly relevant topics due to their harmful consequences for patients and staff. The present study examines variations of intended health care use in urgent and non-urgent cases among the general population. In a cross-sectional telephone survey, a sample of N = 1,204 adults residing in Hamburg, Germany, was randomly drawn. At the beginning of the survey, one of 24 different vignettes (case stories) describing symptoms of inflammatory gastrointestinal diseases were presented to the participants. The vignettes varied in sex (male/female), age (15, 49, 72 years), daytime (Tuesday morning, Tuesday evening), and urgency (low, high). Participants were asked in an open-ended question about their primal intended utilization if they or their children would be affected by such symptoms. Overall, about 14 % chose emergency facilities (ED, ambulance, emergency practice) despite presentation of non-urgent conditions (n = 602). Intended emergency care use varied considerably even if the degree of urgency was comparable. Adolescence, male sex, and symptoms occurring in the evening were associated with increased ED and ambulance use. Inappropriate utilization of ED and ambulance (analyses regarding utilization due to non-urgent problems) was more often observed among male respondents and those with a migration background (1st generation). Information campaigns focused on emergency care use and reorganisation of emergency care wards are possible interventions.

Profiles of met and unmet care needs in the oldest-old primary care patients with depression - results of the AgeMooDe study.

BACKGROUND: Unmet care needs have been associated with an increased risk of depression in old age. Currently, the identification of profiles of met and unmet care needs associated with depressive symptoms is pending. Therefore, this exploratory study aimed to identify profiles of care needs and analyze associated factors in oldest-old patients with and without depression. METHODS: The sample of 1092 GP patients aged 75+ years is based on the multicenter study "Late-life depression in primary care: needs, health care utilization and costs (AgeMooDe)". Depression (i.e. clinically meaningful depressive symptoms) was determined using the Geriatric Depression Scale (GDS) (cutoff score ≥ 4). Needs of patients were assessed using the Camberwell Assessment of Need for the Elderly (CANE). Associated sociodemographic and clinical factors were examined, and latent class analysis identified the need profiles. RESULTS: The main result of the study indicates three need profiles: 'no needs', 'met physical needs', and 'unmet social needs'. Members of the 'met physical needs' (OR = 3.5, 95 %-CI: 2.5-4.9) and 'unmet social needs' (OR = 17.4, 95 %-CI: 7.7-39.7) profiles were significantly more likely to have depression compared to members of the 'no needs' profile. LIMITATIONS: Based on the cross-sectional design, no conclusions can be drawn about the causality or direction of the relationships between the variables. CONCLUSIONS: The study results provide important insights for the establishment of needs-based interventions for GPs. Particular attention should be paid to the presence of unmet social needs in the oldest-old GP patients with underlying depressive symptoms.

The effect of depressive symptoms on quality of life and its different facets in the oldest age population: evidence from the AgeQualiDe prospective cohort study.

PURPOSE: The present study aims to investigate the prospective effect of depressive symptoms on overall QoL in the oldest age group, taking into account its different facets. METHODS: Data were derived from the multicenter prospective AgeCoDe/AgeQualiDe cohort study, including data from follow-up 7-9 and n = 580 individuals 85 years of age and older. Overall QoL and its facets were assessed using the WHOQOL-OLD instrument. The short form of the geriatric depression scale (GDS-15) was applied to assess depressive symptoms. Cognitively impaired individuals were excluded. Linear mixed-effects models were used to assess the effect of depressive symptoms on QoL. RESULTS: Depressive symptoms were significantly associated with overall QoL and each of the different facets of WHOQOL-OLD, also after adjustment for time and sociodemographic characteristics such as age, gender, education, marital status, living situation, and cognitive status. Higher age and single as well as divorced marital status were also associated with a lower QoL. CONCLUSION: This work provides comprehensive longitudinal results on the relationship between depressive symptoms and QoL in the oldest age population. The results underscore the relevance of tailored and targeted care planning and the development of customized interventions.

[Actual Duration of Postgraduate Training of Medical Residents in Germany: Results of the KarMed Study Ten Years After Physician Licensure]. / Reale Dauer der fachärztlichen Weiterbildung in Deutschland ­ Ergebnisse der KarMed-Studie zehn Jahre nach Approbation.

BACKGROUND: Professional qualification as a doctor of medicine includes completion of medical studies and residency. Data on the real duration of residency are currently not assessed systematically in Germany. OBJECTIVES: Our study aimed to analyze data on the real length of residency under consideration of area of expertise (specialization), part-time working, grades after school and medical studies, gender, and parenthood of the physicians in residency. MATERIAL AND METHODS: The KarMed Study's database consists of annual postal surveys throughout the entire residency of medical students, beginning with their "Practical Year" in 2008/2009 until 2019. The study analyzed data six and ten years within this residency period. RESULTS: The majority of the residents was capable of finishing their residency within the minimal time. One significant effect on actual duration of residency was the subject choice. One-third of the female residents had not yet finished their residency after ten years. Partenhood had a significant effect on female residents, but not on male residents. A regression analysis showed (R²corr=0.03, p<0.001) that the duration of residency was associated with the grade received after studying (ß=0.30). Male residents were more satisfied with the overall residency then female residents. DISCUSSION: Structural improvement in postgraduate training needs to be adjusted in terms of parental status. Prospective studies should take the selection process of universities into account and examine its association with the time required to complete residency.

Perceived treatment urgency of common mental disorders in the German population.

Perceived treatment urgency of mental disorders are important as they determine utilization of health care. The aim was to analyze variations in perceived treatment urgency in cases of psychosis (adolescents), alcoholism (adults), and depression (older adults) with two levels of severity each by characteristics of the case and the respondents. A telephone survey (N = 1200) with vignettes describing cases of psychosis, alcoholism, and depression was conducted in Hamburg, Germany. Vignettes varied by symptom severity and sex. Perceived treatment urgency was assessed by three items. A sum scale was calculated. Linear regression models were computed to analyze differences in perceived urgency by characteristics of the case (severity, sex) and the respondents (sex, age, education, migration background, illness recognition, personal affliction). Perceived treatment urgency was significantly higher in severe cases and varied by education. Additionally, regarding psychosis, estimated urgency varied significantly by correct illness recognition. With regard to depression, perceived urgency differed significantly by age and correct illness recognition. Interaction effects between case severity and sociodemographic characteristics of the respondents, personal affliction, and correct recognition of the disorder were found. The identified differences should be considered in the development of interventions on mental health literacy with regard to adequate urgency assessment.

Experiences with remote interpreting tools in primary care settings: a qualitative evaluation of the implementation and usage of remote interpreting tools during a feasibility trial in Germany.

OBJECTIVE: This study aims to evaluate the usage and implementation of video remote (VR) interpreting and telephone remote (TR) interpreting in primary healthcare settings. DESIGN: This publication forms part of a larger three-pronged study in which we compared both remote interpreting modalities to each other and to a control group. This paper conveys the findings of the qualitative evaluation of the implementation and usage of both remote interpreting solutions. The quantitative evaluation of the 6-month intervention period (September 2018-February 2019) has been reported previously. After this period, we conducted focus groups with the healthcare professionals involved. The focus groups were recorded, transcribed verbatim and analysed using the structured qualitative content analysis. SETTING: We provided either VR or TR tools to 10 different primary healthcare practices (general medicine, gynaecology and paediatrics) in the city of Hamburg, Germany. PARTICIPANTS: Three physicians and two physician's assistants took part in the TR focus group. The VR focus group consisted of four physicians. RESULTS: The main topics identified were the importance of communication for diagnostic and therapeutic processes, previous solutions to language barriers, as well as advantages and disadvantages of the two remote interpreting solutions. Advantages included the possibility to adequately communicate with language discordant patients and the high quality of the interpreting. Disadvantages included the habituation time required for new technology as well as time constraints. CONCLUSION: Our evaluation found that these solutions were highly appreciated, if not considered indispensable, for the delivery of appropriate medical care to language-discordant patients. Differences between the two modalities were named and concrete suggestions for improvement were made. Policy-makers should consider providing VR or TR as an adequate and safe interpreting service alternative when professional in-person interpreters are not available or too expensive.

Psychological risk factors for Long COVID and their modification: study protocol of a three-arm, randomised controlled trial (SOMA.COV).

BACKGROUND: Growing evidence suggests that in addition to pathophysiological, there are psychological risk factors involved in the development of Long COVID. Illness-related anxiety and dysfunctional symptom expectations seem to contribute to symptom persistence. AIMS: With regard to the development of effective therapies, our primary aim is to investigate whether symptoms of Long COVID can be improved by a targeted modification of illness-related anxiety and dysfunctional symptom expectations. Second, we aim to identify additional psychosocial risk factors that contribute to the persistence of Long COVID, and compare them with risk factors for symptom persistence in other clinical conditions. METHOD: We will conduct an observer-blinded, three-arm, randomised controlled trial. A total of 258 patients with Long COVID will be randomised into three groups of equal size: targeted expectation management in addition to treatment as usual (TAU), non-specific supportive treatment plus TAU, or TAU only. Both active intervention groups will comprise three individual online video consultation sessions and a booster session after 3 months. The primary outcome is baseline to post-interventional change in overall somatic symptom severity. CONCLUSIONS: The study will shed light onto the action mechanisms of a targeted expectation management intervention for Long COVID, which, if proven effective, can be used stand-alone or in the context of broader therapeutic approaches. Further, the study will enable a better understanding of symptom persistence in Long COVID by identifying additional psychological risk factors.

Medical centres for the homeless in Hamburg - consultation reasons and diagnoses compared to primary care patients in the regular health care system.

BACKGROUND: In Germany, homeless people are entitled to health care within the regular health care system. However, due to their specific living conditions they make little use of these services. In 2013, three Medical centres for the homeless (MCH) were opened in Hamburg to provide general health care. This study aims to analyse the consultation reasons and diagnoses prevalent among the homeless in comparison to regular primary care patients. It also examines the means and obstacles of integrating the homeless into Germany's regular health care system. METHODS: From 2013 to 2014, routine medical data of all patients of the MCH consenting to participate in the study were analysed descriptively, in particular consultation reasons (categorised by ICPC-2), ICD-10 diagnoses and data on health insurance status and the use of the regular health care system. Consultation reasons and diagnoses of homeless patients were compared descriptively with data from regular general practices. Additionally, anonymous data on patient numbers, gender and insurance status was exported from the MCH's software and analysed descriptively for the years 2013 to 2020. RESULTS: A total of 840 homeless patients in 2013 and 2014 gave consent to the evaluation of consultation reasons and diagnoses. The most frequent consultation reasons in the MCH in 2013 were skin conditions (24%), musculoskeletal conditions (16%) and psychological disorders (14%), in GP practices these were musculoskeletal conditions (22%), conditions affecting the digestive system (14%) and skin conditions (12%). Essential (primary) hypertension, diabetes mellitus type 2 and back pain are among the top-10-diagnoses in GP practices, as well as in MCH. With regard to the other top-10-diagnoses, there are clear differences between GP practices and MCH: "Psychological behavioural disorder due to alcohol" and diagnoses in connection with trauma, skin infections and acute respiratory infections stand out in MCH. 35% of the homeless patients reported a lack of health insurance as the reason for "not making use of" the regular health care system, while 10% reported they were unable to visit a regular general practitioner due to physical or psychological reasons. In the years 2013-2020 46% to 73% of the 8.380 MCH patients had no health care insurance. CONCLUSION: Patients consulting the MCH suffer from medical conditions typical for the homeless, namely skin diseases, wounds, injuries and behavioural disorders due to alcohol abuse, but also from "typical" symptoms in regular GP care as cough or lower back symptoms. Consultation reasons mostly are acute illnesses. Chronic diseases are equally present in regular GP and MCH patients, but pose a great challenge for the homeless among other things due to their irregular contact with the health care system. The lack of health insurance poses the greatest hurdle to the integration of the homeless into the regular health care system.

Cost-effectiveness of a specialist palliative care nurse-patient consultation followed by an interprofessional case conference for patients with non-oncological palliative care needs: results of the KOPAL trial.

BACKGROUND: Worldwide, progressive chronic, non-malignant diseases are highly prevalent. Especially with increasing age, they are characterised by high hospitalisation rates and high healthcare costs. Improved interprofessional collaboration between general practitioners (GPs) and specialist palliative home care (SPHC) teams might reduce hospitalisation while improving symptoms and quality of life, or preventing them from deterioration. The aim of this study was to examine the cost-effectiveness of a newly developed intervention in patients with advanced chronic, non-malignant diseases consisting of a structured palliative care nurse-patient consultation followed by an interprofessional telephone case conference. METHODS: The analysis was based on data from 172 participants of the KOPAL multi-centre, cluster randomised controlled trial. Patients with advanced congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), or dementia were randomised into intervention group (IG) and control group (CG, usual care). Cost-effectiveness was examined over 48 weeks from a societal and healthcare payer's perspective. Effects were quantified as quality-adjusted life years (QALYs, EQ-5D-5L). Incremental cost-effectiveness ratios were calculated and cost-effectiveness acceptability curves were constructed. RESULTS: Baseline imbalances in costs and effects could be observed between IG and CG. After adjusting for these imbalances and compared to the CG, mean costs in the IG were non-significantly higher from a societal and lower from a payer's perspective. On the effect side, the IG had marginally lower mean QALYs. The results were characterized by high statistical uncertainty, indicated by large confidence intervals for the cost and effect differences between groups and probabilities of cost-effectiveness between 18% and 65%, depending on the perspective and willingness-to-pay. CONCLUSIONS: Based on the results of this study, the cost-effectiveness of the KOPAL intervention was uncertain. The results highlighted (methodological) challenges of economic evaluations in patients with chronic, non-malignant diseases related to sample size, heterogeneity of participants, and the way the intervention effectiveness is typically captured in economic evaluations.

Family History of Dementia in Old-Age Participants with Subjective Memory Complaints Predicts Own Risk for Dementia in a Longitudinal Multi-Center Cohort Study.

BACKGROUND: Subjective memory complaints and family history of dementia are possibly intertwined risk factors for the own subsequent dementia risk and Alzheimer's disease. However, their interaction has rarely been studied. OBJECTIVE: To study the association between subjective memory complaints and family history of dementia with regard to the own subsequent risk of dementia. METHODS: Cross-sectional and longitudinal analyses over a follow-up period of up to 13 years were conducted in a population sample of participants without dementia at baseline (n = 3,256, mean age = 79.62 years), using group comparisons and Cox proportional hazards models. RESULTS: Cross-sectionally, participants with subjective memory complaints were significantly more likely to report family history of dementia. Longitudinally, family history of dementia (FH) was significantly associated with subsequent dementia in the subjective memory complaints (SMC) group, but not in those without SMC. A relative excess risk due to interaction analysis confirmed a significant FHxSMC-interaction. CONCLUSIONS: Family history of dementia was a predictor of incident dementia in those with SMC, which can serve as an additional, clinically relevant criterion to gauge the risk of dementia in older-aged subjects with SMC with and without objective cognitive impairment.

An Investigation into the Relationship of Circulating Gut Microbiome Molecules and Inflammatory Markers with the Risk of Incident Dementia in Later Life.

The gut microbiome may be involved in the occurrence of dementia primarily through the molecular mechanisms of producing bioactive molecules and promoting inflammation. Epidemiological evidence linking gut microbiome molecules and inflammatory markers to dementia risk has been mixed, and the intricate interplay between these groups of biomarkers suggests that their joint investigation in the context of dementia is warranted. We aimed to simultaneously investigate the association of circulating levels of selected gut microbiome molecules and inflammatory markers with dementia risk. This case-cohort epidemiological study included 805 individuals (83 years, 66% women) free of dementia at baseline. Plasma levels of 19 selected gut microbiome molecules comprising lipopolysaccharide, short-chain fatty acids, and indole-containing tryptophan metabolites as well as four inflammatory markers measured at baseline were linked to incident all-cause (ACD) and Alzheimer's disease dementia (AD) in binary outcomes and time-to-dementia analyses. Independent of several covariates, seven gut microbiome molecules, 5-hydroxyindole-3-acetic acid, indole-3-butyric acid, indole-3-acryloylglycine, indole-3-lactic acid, indole-3-acetic acid methyl ester, isobutyric acid, and 2-methylbutyric acid, but no inflammatory markers discriminated incident dementia cases from non-cases. Furthermore, 5-hydroxyindole-3-acetic acid (hazard ratio: 0.58; 0.36-0.94, P = 0.025) was associated with time-to-ACD. These molecules underpin gut microbiome-host interactions in the development of dementia and they may be crucial in its prevention and intervention strategies. Future larger epidemiological studies are needed to confirm our findings, specifically in exploring the repeatedly measured circulating levels of these molecules and investigating their causal relationship with dementia risk.

Expanded nursing competencies to improve person-centred care for nursing home residents with complex health needs (Expand-Care): study protocol for an exploratory cluster-randomised trial.

INTRODUCTION: Older age is associated with multimorbidity, chronic diseases and acute deteriorations and leads to complex care needs. Nursing home residents are more often unnecessarily transferred to emergency departments or hospitals than community dwellers-largely due to a lack of qualified staff and diffusion of responsibility in the institutions. In Germany, only few academically trained nurses work in nursing homes, and their potential roles are unclear. Therefore, we aim to explore feasibility and potential effects of a newly defined role profile for nurses with bachelors' degree or equivalent qualification in nursing homes. METHODS AND ANALYSIS: A pilot study (Expand-Care) with a cluster-randomised controlled design will be conducted in 11 nursing homes (cluster) in Germany, with an allocation ratio of 5:6 to the intervention or control group, aiming to include 15 residents per cluster (165 participants in total). Nurses in the intervention group will receive training to perform role-related tasks such as case reviews and complex geriatric assessments. We will collect data at three time points (t0 baseline, t1 3 months and t2 6 months after randomisation). We will measure on residents' level: hospital admissions, further health services use and quality of life; clinical outcomes (eg, symptom burden), physical functioning and delivery of care; mortality, adverse clinical incidents and changes in care level. On nurses' level, we will measure perception of the new role profile, competencies and implementation of role-related tasks as part of the process evaluation (mixed methods). An economic evaluation will explore resource use on residents' (healthcare utilisation) and on nurses' level (costs and time expenditure). ETHICS AND DISSEMINATION: The ethics committees of the University of Lübeck (Nr. 22-162) and the University Clinic Hamburg-Eppendorf (Nr. 2022-200452-BO-bet) approved the Expand-Care study. Informed consent is a prerequisite for participation. Study results will be published in open-access, peer-reviewed journals and reported at conferences and in local healthcare providers' networks. TRIAL REGISTRATION NUMBER: DRKS00028708.

Development of an interprofessional person-centred care concept for persons with care needs living in their own homes (interprof HOME): study protocol for a mixed-methods study.

INTRODUCTION: People receiving home care usually have complex healthcare needs requiring the involvement of informal caregivers and various health professionals. In this context, successful collaboration is an important element of person-centred care, which is often insufficiently implemented. Consequences might be found in avoidable hospitalisations. The aim of the study is to develop a care concept to improve person-centred interprofessional collaboration for people receiving home care considering the perspectives of all person groups involved. METHODS AND ANALYSIS: This study uses a mixed-methods design consisting of a literature review, several qualitative inquiries, a cross-sectional quantitative study and a final structured workshop. After a literature review (work package (WP) 1), we will explore the perspectives of people receiving home care (n=20), their relatives (n=20) and representatives of statutory health insurances (n=5) in semistructured interviews (WP2). Moreover, 100 individuals of each group (people receiving home care, relatives, registered nurses, general practitioners and therapists) involved in home care will answer a survey on collaboration that will be analysed descriptively (WP3). Additionally, monoprofessional focus groups (n=9) of registered nurses, general practitioners and therapists, respectively, will discuss current practices. Data will be analysed by qualitative content analysis. Best practice cases (n=8) will be analysed by a case-based qualitative content analysis based on data of observations of home visits and interviews (WP4). The findings of WP2 will be discussed in mixed focus groups (n=4) with 10 participants each (WP5). Considering the results of joint displays of WP3, WP4 and WP5, the interprofessional care concept and its implementation will be elaborated in an expert workshop (WP6). ETHICS AND DISSEMINATION: Ethical approval was obtained from all ethics committees of the project partners. Study results will be disseminated through publications, conference presentations, student education and advanced training of health professionals. TRIAL REGISTRATION NUMBER: NCT05149937.
