[Clinical Practice Guidelines for Vaccine Management in Ambulatory Care: a Systematic Review Following the AGREE II Approach]. / Impfstoffmanagement in der ambulanten Versorgung: ein systematischer Review internationaler Empfehlungen und Implikationen für das deutsche Gesundheitswesen.

BACKGROUND: Breaches in the cooling chain with exposure of vaccines to temperatures outside the target range of +2°C to +8°C may reduce their efficacy and impair immune responses. Following the Appraisal of Guidelines for Research and Evaluation (AGREE II) approach, this review assesses the quality and content of international clinical practice guidelines on vaccine management. The results were used to derive recommendations for the vaccine management in ambulatory care in Germany. METHODS: Based on a systematic search and screening process with predefined criteria, the selected guidelines were rated by three reviewers using the AGREE II domains: scope and purpose, stake-holder involvement, rigor of development, clarity of presentation, applicability, and editorial independence. The content of the guidelines was retrieved and summarized according to five predefined categories: cold chain, responsibilities, equipment, storage, and monitoring. The review was registered in PROSPERO (CRD42021270524). RESULTS: A total of nine clinical practice guidelines were selected for evaluation. The sum score of the documents varied between 17% to 89% of the maximum possible score. All guidelines included recommendations in the five content categories but differed in detail. The key recommendations were: a) continuous cold chain required; b)≥2 trained, responsible staff members; c) storage in original wrappings; d) appropriate, preferably purpose-built refrigerator with two-point thermometer or data logger; e) routinely implemented monitoring processes including daily temperature recording. A public monitoring system was recommended in some guidelines. CONCLUSION: Our systematic review identified key information for vaccine storage and management to support the future development of German recommendations for vaccine storage.

Individual courses and determinants of fear of cancer recurrence in long-term breast cancer survivors with and without recurrence.

OBJECTIVE: This study investigated the prevalence, individual courses, and determinants of fear of cancer recurrence (FoR) in long-term breast cancer survivors (BCSs) with and without recurrence. METHODS: A total of 184 breast cancer survivors were surveyed at four measurement time points: during hospitalization (T1), 10 weeks (T2), 40 weeks (T3), and 5-6 years (T4) after hospital discharge. Descriptive statistics, chi-square tests, and logistic regression were performed. RESULTS: Respondents were females and 57 years old, on average. At T1, T3, and T4, 54.8%, 31.6%, and 29.7% of BCSs, respectively, were classified as having dysfunctional levels of FoR. Dysfunctional FoR decreased from T1 to T3 (χ2(1) = 17.11, p = 0.000; N = 163) and remained stable afterwards. Eight subgroups of individual courses of FoR over time could be described: (1) constant functional FoR; (2) constant dysfunctional FoR; (3) improving from dysfunctional to functional FoR from T1 to T3; (4) improving from dysfunctional to functional FoR from T3 to T4; (5) worsening from functional to dysfunctional FoR from T1 to T3; (6) worsening from functional to dysfunctional FoR from T3 to T4; (7) dysfunctional FoR at T1 and T4, and functional FoR in between; and (8) functional FoR at T1 and T4, and dysfunctional FoR in between. Logistic regression analysis revealed that being divorced/widowed, showing high levels of fatigue, being treated by chemotherapy, and having low confidence in treatment were associated with dysfunctional FoR 5 to 6 years after diagnosis (Nagelkerkes' Pseudo-R2 = 0.648). CONCLUSIONS: The findings reveal that FoR is a significant issue in long-term BCSs and has the potential to become a persistent psychological strain. We emphasize the need for increased awareness of FoR among BCSs and the need for support programs.

General practitioners' deprescribing decisions in older adults with polypharmacy: a case vignette study in 31 countries.

BACKGROUND: General practitioners (GPs) should regularly review patients' medications and, if necessary, deprescribe, as inappropriate polypharmacy may harm patients' health. However, deprescribing can be challenging for physicians. This study investigates GPs' deprescribing decisions in 31 countries. METHODS: In this case vignette study, GPs were invited to participate in an online survey containing three clinical cases of oldest-old multimorbid patients with potentially inappropriate polypharmacy. Patients differed in terms of dependency in activities of daily living (ADL) and were presented with and without history of cardiovascular disease (CVD). For each case, we asked GPs if they would deprescribe in their usual practice. We calculated proportions of GPs who reported they would deprescribe and performed a multilevel logistic regression to examine the association between history of CVD and level of dependency on GPs' deprescribing decisions. RESULTS: Of 3,175 invited GPs, 54% responded (N = 1,706). The mean age was 50 years and 60% of respondents were female. Despite differences across GP characteristics, such as age (with older GPs being more likely to take deprescribing decisions), and across countries, overall more than 80% of GPs reported they would deprescribe the dosage of at least one medication in oldest-old patients (> 80 years) with polypharmacy irrespective of history of CVD. The odds of deprescribing was higher in patients with a higher level of dependency in ADL (OR =1.5, 95%CI 1.25 to 1.80) and absence of CVD (OR =3.04, 95%CI 2.58 to 3.57). INTERPRETATION: The majority of GPs in this study were willing to deprescribe one or more medications in oldest-old multimorbid patients with polypharmacy. Willingness was higher in patients with increased dependency in ADL and lower in patients with CVD.

Effects of the dementia care toolbox on personnel's self-reported confidence in patient care: a CRT in general practices.

BACKGROUND: In rapidly aging populations, general practitioners (GPs) are challenged in dementia care of patients with and without migration background. Uncertainties in treating dementia in migrant patients due to language barriers or information deficits are reported. To address these deficits, we developed the Dementia Care Toolbox which was judged helpful by GP practice personnel. This two-armed cluster-randomised trial (CRT) investigated the effects of this toolbox on German GPs' and practice assistants' (PrAs) attitudes and confidence in dementia care, especially in patients with migration background. METHODS: A total of 32 GP practices were recruited and randomised into intervention (toolbox use for 3 months) and waiting-list control (toolbox after follow-up). After 3 months all participating GPs and PrAs received a standardised questionnaire addressing their levels of self-reported confidence in dementia care for patients with and without migration background. A generalized estimating equation model that took practice cluster effects into account was applied to assess GPs and PrAs self-reported confidence in dementia care in patients with and without migration background. RESULTS: Overall, the intervention had no significant effect on self-reported confidence in dementia care. However, the use of the dementia care toolbox showed a tendency for a learning effect on knowledge about local support structures for migrant patients with dementia (odds ratio 1.43; 95% CI 0.68-3.03, p = 0.35) and for less communication difficulties with dementia patients in general (odds ratio 0.72; 95% CI 0.33-1.56; p = 0.40). Moreover, intervention practices showed a tendency towards more awareness of own limitations: less self-confidence regarding answering questions (odds ratio 0.82; 95% CI 0.36-1.86, p = 0.64) and providing information for patients with migration background (odds ratio 0.60; 95% CI 0.25-1.45, p = 0.26). CONCLUSION: The Toolbox Dementia Care increased awareness on the respective topic. Given a small sample size, further studies on its effectiveness in primary care are needed.

Acceptance and self-reported use of a dementia care toolbox by general practice personal: results from an intervention study in German practices.

BACKGROUND: Dementia is an age-related syndrome that is estimated to affect 46.8 million people worldwide (2015). In ageing populations, the prevalence of dementia is expected to increase. General practitioners (GPs) are often the first to be contacted when signs of dementia appear. This cluster-randomised trial (CRT) investigates the effects of a dementia care toolbox mailed to GP practices to facilitate dementia care. It contained patient brochures and posters for the waiting room in three languages, information cards for professionals and practical tools in three languages. The GPs' and practice assistants' (PrAs) use of and opinion about the toolbox is reported here. METHODS: Three months after receiving the toolbox, participating GPs and PrAs were sent a standardised, self-administered questionnaire asking about the use and helpfulness of the various toolbox items by mail. RESULTS: A total of 50 GPs and PrAs (14 GPs and 36 PrAs) from 15 practices completed the questionnaire. Of the participants, 82.0% reported using at least one of the tools, while 18.0% had used none. In descending order, the patient brochures (70.0%), the information card (58.0%) and the poster (40.0%) were used. In general, the brochures (52.1%), the information card (44.9%) as well as the poster (28.6%) were perceived as helpful. CONCLUSION: Overall, the dementia toolbox was widely accepted by both professional groups. Future research should investigate long-term effects of information strategies for GP practice settings.

[Addressing Issues of Living Will and Power of Attorney in Patients With Dementia - A Cross-Sectional Study Among German General Practitioners]. / Hausärztlicher Umgang mit Patientenverfügung und Vorsorgevollmacht bei Demenzpatienten ­ Eine Querschnittsstudie unter deutschen Hausärzten.

OBJECTIVES: Issues of living will and power of attorney must be addressed as early as possible in dementia patients because of their decreasing independence and ability to act for themselves. The aim of this study was to investigate whether general practitioners (GPs), who usually have long-standing and regular contact with this group of patients, address these precautionary measures and if there is any association between this approach and further communication and educational behaviour of doctors. METHODS: A cross-sectional survey, using standardized, written questionnaires, was conducted in a random sample of 982 GPs in North Rhine-Westphalia in western Germany between October 2017 and January 2018. Descriptive statistical as well as logistic regression analyses were carried out using IBM SPSS Statistics, version 24. RESULTS: A total of 339 GPs responded to the survey questionnaire (response rate: 34.5%). A majority of GPs (70.1%) agreed totally or partially that it was necessary to address their dementia patients on living will and power of attorney; GPs who were more confident in communicating a dementia diagnosis reported addressing the issue of documents for the end of life more frequently (aOR: 1.97; 95%-CI: 1.17-3.33). Older GPs with greater knowledge of regional services for dementia patients also tended to address this topic more frequently. CONCLUSIONS: General practitioners make a major contribution to help dementia patients and their relatives to plan ahead at an early stage of the disease. It can be concluded from our results that GPs' knowledge and experiences about dementia and local services, as well as how to deal with those affected should be improved in order to optimise communication on living will and power of attorney as precautionary measures.

Improving the vaccination status of liver transplant patients: Effectiveness of personally addressing patients and written recommendations to family physicians after 3 years.

BACKGROUND: After documenting insufficient vaccinations in 444 liver transplant (LT) patients, we investigated the effects of a combined strategy (addressing both patients and primary care physicians) on immunization prevalences after a 3-year follow-up. METHODS: The primary care physicians of all adult LT patients from a university center received a written recommendation addressing immunization needs. Patients were asked for their vaccination documents by phone. Changes in immunization rates for vaccine-preventable diseases after the intervention were calculated based on patients' immunization documents from 2014-2016. RESULTS: The study cohort consisted of 401 patients. Prevalence rates for all vaccinations improved during the intervention period compared to the baseline study: tetanus from 88.3% to 92.8%, diphtheria from 80.0% to 89.0%, hepatitis A from 50.1% to 60.8%, hepatitis B from 66.3% to 77.1%, and pneumococci from 62.8% to 76.3%. The influenza vaccination rate improved, but remained at a low level before (2010:13%, 2011:11.5%, 2012:19%) and during the intervention (2014:27.4%, 2015:24.4%, 2016:23.2%). Despite these vaccinations, the prevalence rates of the quality indicators standard vaccinations completed (2013:17.2%; 2016:21.2%), indicated vaccinations completed (2013:2.7%, 2016:4.5%), and all vaccinations completed (2013:1%; 2016 1.5%) improved only slightly. CONCLUSIONS: Our results demonstrated that intensified communication by written information to the primary care physician and phone calls to the patients improved the number of vaccinations. Nonetheless, a potential for further improvement persists, especially with regard to annual influenza vaccinations.

Cost-related medication nonadherence among over-indebted individuals enrolled in statutory health insurance in Germany: a cross-sectional population study.

BACKGROUND: Millions of citizens in high-income countries face over-indebtedness that implies being unable to cover payment obligations with available income and assets on an ongoing basis. Studies have shown an association between over-indebtedness and health outcomes, independent of standard socioeconomic status measures. Patterns of cost-related medication nonadherence (CRN) among over-indebted individuals are yet unclear. The aim of this study was to examine the frequency of nonadherence to prescribed medications due to cost, and to identify risk factors for CRN among over-indebted individuals in Germany. METHODS: In 2017, we conducted a cross-sectional survey among over-indebted individuals recruited in 70 debt advice agencies in North Rhine-Westphalia, Germany. Data on CRN in the last 12 months (i.e. not filling prescriptions, skipping or decreasing doses of prescribed medication due to financial problems) were collected by a survey using a self-administered written questionnaire that was returned by 699 individuals with a response rate of 50.2%. Prevalence of CRN was assessed using descriptive statistics. Multiple logistic regression analysis was performed to examine risk factors of CRN, including participants enrolled in statutory health insurance with complete data (n = 521). RESULTS: The prevalence of CRN was 33.6%. The chronically ill had significantly greater odds of cost-related medication nonadherence (aOR 1.96; 95% CI 1.27-3.03) than individuals without a chronic illness. CRN was more likely to occur in individuals who had discussed financial problems with their general practitioner (aOR 1.58; 95% CI 1.01-2.47). There was no association between CRN and other sociodemographic factors or socioeconomic status. CONCLUSIONS: Medication nonadherence due to financial pressures is common among over-indebted citizens enrolled in statutory health insurance in Germany. Stakeholders in social policy, research and health care need to address over-indebtedness to develop strategies to safeguard access to relevant medications, especially among those with high morbidity.

Chronic stress, work-related daily challenges and medicolegal investigations: a cross-sectional study among German general practitioners.

BACKGROUND: The prevalence of chronic stress among German general practitioners (GPs) was shown to be twice as high as in the general population. Because chronic stress negatively influences well-being and poor physician well-being is associated with poor patient outcomes, targeted strategies are needed. This analysis focuses on work-related factors associated with high chronic stress in GPs. METHODS: This cross-sectional study measured chronic stress among German GPs using the validated and standardized Trier Inventory for the Assessment of Chronic Stress (TICS-SSCS). Based on the TICS, GPs were categorized as either having low strain (≤ 25th percentile) or high strain (≥ 75th percentile) due to chronic stress. Questions on work-related challenges assessed the frequency and the subjectively perceived strain of single challenges. For exploratory analyses, these items were combined to dichotomous variables reflecting challenges that are common and that cause high strain. Variables significant in bivariate analyses were included in a multivariate logistic regression model analyzing their association with high chronic stress. RESULTS: Data of 109 GPs categorized as having low strain (n = 53) or high strain (n = 56) due to chronic stress were analyzed. Based on bivariate analyses, challenges regarding personnel matters, practice software, complexity of patients, difficult patients, care facilities, scheduling of appointments, keeping medical records up-to-date, fee structures, and expectations versus reality of care were included in the regression model. Keeping medical records up-to-date had the strongest association with high chronic stress (odds ratio 4.95, 95% confidence interval 1.29-19.06). A non-significant trend showed that medicolegal investigations were more common among GPs with high chronic stress. CONCLUSIONS: This exploratory research shows that chronic stress is predominantly associated with administrative challenges. Treatment documentation, which represents a legal safeguard and is closely linked to existential concerns, has the strongest influence.

Challenges in diagnosing dementia in patients with a migrant background - a cross-sectional study among German general practitioners.

BACKGROUND: Diagnosing dementia, a syndrome affecting 35.6 million people worldwide, can be challenging, especially in patients with a migrant background. Language barriers and language-based diagnostic tools, cultural differences in the perception of the syndrome as well as restricted access to healthcare can influence medical care. For the first time in Germany, this study investigates whether German general practitioners (GPs) feel prepared to meet the diagnostic needs of these patient groups and whether there are challenges and support needs. METHODS: A cross-sectional study among a random sample of 982 general practitioners in Germany was conducted from October 2017 to January 2018 (response rate: 34.5%). A self-developed, written, standardised questionnaire was used. Descriptive statistics as well as multiple logistic regression analyses were performed using data of 326 GPs. RESULTS: Ninety-six percent of GPs reported having experienced barriers at least once. Uncertainties in diagnosing dementia in patients with a migrant background were indicated by 70.9%. There was no significant association between uncertainties in diagnosing dementia and GPs' sociodemographic characteristics. The most frequently reported barriers were language barriers that affected or prevented diagnostics (89.3%) and information deficits in patients with a migrant background (59.2%). Shameful interaction or lack of acceptance of the syndrome was also common (55.5%). A demand for more information about the topic was expressed by 70.6% of GPs. CONCLUSIONS: Public health measures supporting GPs in their interaction with patients with a migrant background as well as information and services for dementia patients are needed. Efforts to facilitate access to interpreting services and to focus on people with a migrant background in healthcare are necessary.

Electronic reminders to facilitate longitudinal care: a mixed-methods study in general practices.

BACKGROUND: Longitudinal, patient-centered care represents a challenge for general practitioners (GPs), and in this context, reminder systems can offer targeted support. This study aimed to identify details of such reminders: (1) contents of care addressed, (2) their mode of display in the electronic health record (EHR), (3) their visual appearance, (4) personnel responsibilities for editing and applying reminders, and (5) use of reminders for patient recall. METHODS: This mixed-methods study comprised (1) a cross-sectional survey among 185 GP practices from a German university network, and (2) structured observations of reminder utilization in six practices based on a clinical vignette describing a multimorbid senior with 26 care needs. Descriptive statistics were performed for survey data. The practice observations were analyzed by portraying different types of reminders. RESULTS: Seventy-three of 185 practices completed the survey (39.5%): 98.6% reported using reminders in the EHR. Frequent care contents addressed were allergies/adverse drug events (95.8%), preventive measures (93.1%), participation in disease management programs (87.5%), chronic diseases (75.0%), and upcoming vaccinations (68.1%). Practice observations showed a variety of mainly self-configured reminders. In a patients' EHR, information was displayed (1) compiled in a separate field, (2) scattered throughout the EHR, and/or (3) in a pop-up window. The visual appearance of electronic reminders varied: (1) colored fields with short text, (2) EHR entries and/or billing codes in pre-defined colors, (3) abbreviations within the treatment documentation, (4) symbols within the treatment documentation, (5) symbols linked to free text fields, and (6) traffic light schemes. Five practices self-designed reminders 'as needed'; one practice applied an EHR-embedded, pre-defined reminder system. Practices used reminders for a mean of 13.3 of the 26 aspects of care detailed in the clinical vignette (range: 9-21; standard deviation (SD): 4.3). Practices needed 20-35 min (mean: 27.5; SD: 6.1) to retrieve the information requested. CONCLUSIONS: Most GP practices use self-designed, visual reminders for some aspects of care, yet data-based, sophisticated solutions are needed to improve longitudinal care.

Multiple procedures and cumulative individual radiation exposure in interventional cardiology: A long-term retrospective study.

INTRODUCTION: Various studies address discrepancies between guideline recommendations for coronary angiographies and clinical practice. While the issue of the appropriateness of recurrent angiographies was studied focusing on the role of the cardiologist, little is known about individual patients' histories and the associated radiation exposures. METHODS: We analyzed all patients with coronary artery disease (CAD) in an academic teaching practice who underwent at least one angiography with or without intervention between 2004 and 2009. All performed angiographies in these patients were analyzed and rated by three physicians for appropriateness levels according to cardiology guidelines. Typical exposure data from the medical literature were used to estimate individual radiation exposure. RESULTS: In the cohort of 147 patients, a total of 441 procedures were analyzed: between 1981 and 2009, three procedures were performed per patient (range 1-19) on average. Appropriateness ratings were 'high/intermediate' in 71%, 'low/no' in 27.6% and data were insufficient for ratings in 1.4%. Procedures with 'low/no' ratings were associated with potentially avoidable exposures of up to 186 mSv for single patients. CONCLUSIONS: Using retrospective data, we exemplify the potential benefit of guideline adherence to decrease patients' radiation exposures. KEY POINTS: • A cohort study of 147 patients showed 27.6% low appropriateness procedures. • Potentially avoidable radiation exposure cumulated up to about 186 mSv for single patients. • Predisposing factors were prior bypass surgery and first treatment in a tertiary centre. • 7.5% of the patients received 58% of the potentially avoidable radiation exposure. • The benefits of guideline adherence in decreasing patient radiation exposure are exemplified.

Effectiveness of the online-eLearning program KeepCoool at improving the vaccine cold chain in general practices.

BACKGROUND: Protecting vaccines from freeze damage is a poorly addressed problem. We describe the effectiveness of the eLearning KeepCoool on cold chain maintenance in general practices. METHODS: For this intervention study, temperatures of vaccine refrigerators were logged at one-minute intervals. Personnel from practices with cold chain breaches was offered the eLearning. The primary outcome was the intervention's effectiveness to achieve temperatures in the target range (2 to 8°C) in the sixth week (follow-up) compared to the first (baseline). Using continuous temperature data, a generalized additive model for location, scale and shape was estimated. RESULTS: The practice response rate was 38% (64 of 168). At baseline, 73% of the practices and 68% of the refrigerators (51 of 75) showed cold chain breaches. 47% of the practices (n = 22 with 24 refrigerators) participated in the eLearning (55 physicians and practice assistants). At follow-up, 17% of those refrigerators were in the target range continuously, 38% reached targets 95% of the time while always >0°C, and temperatures ≤0°C decreased by 63%. Based on 2 million temperature data, the average Euclidian distance based on regression showed a significant improvement (p<0.05). CONCLUSION: The eLearning KeepCoool improved the practices´ vaccine cold chain. It is freely available at https://keepcoool.ukbonn.de.

Associations between COVID-19 Pandemic-Related Overtime, Perceived Chronic Stress and Burnout Symptoms in German General Practitioners and Practice Personnel-A Prospective Study.

BACKGROUND: The mental burdens of general practitioners (GPs) and practice assistants (PrAs) during the COVID-19 pandemic are well investigated. Work-related conditions like overtime are known to contribute to perceived chronic stress and burnout symptoms. However, there is limited evidence regarding the specific mechanisms, which link pandemic-related overtime, chronic stress and burnout symptoms. This study used data from the IMPROVEjob trial to improve psychological well-being in general practice personnel. METHODS: This prospective study with 226 German GPs and PrAs used the baseline (pre-pandemic: October 2019 to March 2020) and follow-up data (pandemic: October 2020 to April 2021) of the IMPROVEjob trial. Overtime was self-reported as hours above the regular work time. Perceived chronic stress was assessed using the Trier Inventory for the Assessment of Chronic Stress Screening Scale (TICS-SSCS), while burnout symptoms were evaluated using a short version of the Maslach Burnout Inventory (MBI). A mediation analysis investigated the differences of the three main variables between pre-pandemic and pandemic periods. RESULTS: Burnout symptoms increased significantly from baseline to follow-up (p = 0.003). Overtime correlated positively with burnout symptoms (Total Effect: 0.13; 95% CI: 0.03, 0.23). Decomposition of the total effect revealed a significant indirect effect over perceived chronic stress (0.11; 95% CI: 0.06, 0.18) and no significant direct effect (0.02; 95% CI: -0.08, 0.12), indicating a full mediation. CONCLUSION: In this large longitudinal study, pandemic-related overtime led to significantly higher levels of burnout symptoms, linked by a pathway through perceived chronic stress. Future prevention strategies need to aim at reducing the likelihood of overtime to ensure the mental well-being of practice personnel.

Use of the FallAkte Plus System as an IT Infrastructure for the North Rhine-Westphalian General Practice Research Network: Mixed Methods Usability Study.

BACKGROUND: Primary care research networks can generate important information in the setting where most patients are seen and treated. However, this requires a suitable IT infrastructure (ITI), which the North Rhine-Westphalian general practice research network is looking to implement. OBJECTIVE: This mixed methods research study aims to evaluate (study 1) requirements for an ITI and (study 2) the usability of an IT solution already available on the market, the FallAkte Plus (FA+) system for the North Rhine-Westphalian general practice research network, which comprises 8 primary care university institutes in Germany's largest state. METHODS: In study 1, a survey was conducted among researchers from the institutes to identify the requirements for a suitable ITI. The questionnaire consisted of standardized questions with open-ended responses. In study 2, a mixed method approach combining a think-aloud approach and a quantitative survey was used to evaluate the usability and acceptance of the FA+ system among 3 user groups: researchers, general practitioners, and practice assistants. Respondents were asked to assess the usability with the validated system usability scale and to test a short questionnaire on vaccination management through FA+. RESULTS: In study 1, five of 8 institutes participated in the requirements survey. A total of 32 user requirements related primarily to study management were identified, including data entry, data storage, and user access management. In study 2, a total of 36 participants (24 researchers and 12 general practitioners or practice assistants) were surveyed in the mixed methods study of an already existing IT solution. The tutorial video and handouts explaining how to use the FA+ system were well received. Researchers, unlike practice personnel, were concerned about data security and data protection regarding the system's emergency feature, which enables access to all patient data. The median overall system usability scale rating was 60 (IQR 33.0-85.0), whereby practice personnel (median 82, IQR 58.0-94.0) assigned higher ratings than researchers (median 44, IQR 14.0-61.5). Users appreciated the option to integrate data from practices and other health care facilities. However, they voted against the use of the FA+ system due to a lack of support for various study formats. CONCLUSIONS: Usability assessments vary markedly by professional group and role. In its current stage of development, the FA+ system does not fully meet the requirements for a suitable ITI. Improvements in the user interface, performance, interoperability, security, and advanced features are necessary to make it more effective and user-friendly. Collaborating with end users and incorporating their feedback are crucial for the successful development of any practice network research ITI.

The Predominance of the Health-Promoting Patterns of Work Behavior and Experience in General Practice Teams-Results of the IMPROVEjob Study.

This study aims to identify the distribution of the "Work-related behavior and experience patterns" (Arbeitsbezogenes Verhaltens-und Erlebnismuster, AVEM) in general practitioners and their teams by using baseline data of the IMPROVEjob study. Members of 60 general practices with 84 physicians in a leadership position, 28 employed physicians, and 254 practice assistants participated in a survey in 2019 and 2020. In this analysis, we focused on AVEM variables. Age, practice years, work experience, and working time were used as control variables in the Spearman Rho correlations and analysis of variance. The majority of the participants (72.1%) revealed a health-promoting pattern (G or S). Three of eleven AVEM dimensions were above the norm for the professional group "employed physicians". The AVEM dimensions "striving for perfection" (p < 0.001), "experience of success at work" (p < 0.001), "satisfaction with life" (p = 0.003), and "experience of social support" (p = 0.019) differed significantly between the groups' practice owners and practice assistants, with the practice owners achieving the higher values, except for experience of social support. Practice affiliation had no effect on almost all AVEM dimensions. We found a high prevalence of AVEM health-promoting patterns in our sample. Nearly half of the participants in all professional groups showed an unambitious pattern (S). Adapted interventions for the represented AVEM patterns are possible and should be utilized for maintaining mental health among general practice teams.

Stroke knowledge among diabetics: a cross-sectional study on the influence of age, gender, education, and migration status.

BACKGROUND: Stroke campaigns are educating about the need to immediately contact the emergency medical system if symptoms occur. Despite higher stroke rates among patients with diabetics and some migrant populations, there are few data about stroke knowledge in these groups. METHODS: We performed a cross-sectional questionnaire survey among 250 diabetes patients from Germany and Turkey in a primary care and diabetes practice center. The two-page questionnaire asked for stroke knowledge and socio-demographic data. Also, medical and communication data were obtained. Stroke knowledge was defined as good if a participant knew (1) at least two stroke symptoms (good symptom knowledge) and (2) that immediate hospital admission or an emergency call is necessary in case of stroke symptoms (good action knowledge). RESULTS: A total of 231 of 250 patients took part in the survey (participation rate 92.4%) with 134 natives (53.6%), 84 migrants from Turkey (33.6%) and 13 migrants (5.2%) from other countries. Comparing natives and migrants from Turkey good symptom knowledge was documented in 52.8% of the participants, good action knowledge in 67.9%, and good stroke knowledge in nearly forty percent (39.4%) of patients (n = 218). A logistic regression analysis showed better stroke knowledge if patients were younger than 61 years, had good language abilities and were living in an one-generation household (p < 0.05), while gender, years since migration and diabetes control did not play a role. CONCLUSIONS: We documented stroke knowledge deficits among patients with diabetes, both natives and migrants. Additional information strategies for these high risk populations are needed.

Prediction of Chronic Stress and Protective Factors in Adults: Development of an Interpretable Prediction Model Based on XGBoost and SHAP Using National Cross-sectional DEGS1 Data.

BACKGROUND: Chronic stress is highly prevalent in the German population. It has known adverse effects on mental health, such as burnout and depression. Known long-term effects of chronic stress are cardiovascular disease, diabetes, and cancer. OBJECTIVE: This study aims to derive an interpretable multiclass machine learning model for predicting chronic stress levels and factors protecting against chronic stress based on representative nationwide data from the German Health Interview and Examination Survey for Adults, which is part of the national health monitoring program. METHODS: A data set from the German Health Interview and Examination Survey for Adults study including demographic, clinical, and laboratory data from 5801 participants was analyzed. A multiclass eXtreme Gradient Boosting (XGBoost) model was constructed to classify participants into 3 categories including low, middle, and high chronic stress levels. The model's performance was evaluated using the area under the receiver operating characteristic curve, precision, recall, specificity, and the F1-score. Additionally, SHapley Additive exPlanations was used to interpret the prediction XGBoost model and to identify factors protecting against chronic stress. RESULTS: The multiclass XGBoost model exhibited the macroaverage scores, with an area under the receiver operating characteristic curve of 81%, precision of 63%, recall of 52%, specificity of 78%, and F1-score of 54%. The most important features for low-level chronic stress were male gender, very good general health, high satisfaction with living space, and strong social support. CONCLUSIONS: This study presents a multiclass interpretable prediction model for chronic stress in adults in Germany. The explainable artificial intelligence technique SHapley Additive exPlanations identified relevant protective factors for chronic stress, which need to be considered when developing interventions to reduce chronic stress.

More GP Consultations by Violence Victims: Results from the Representative German DEGS1 Study.

Violence is a growing public health problem influencing physical and mental health. Victims tend to contact medical care in the first place, yet a discrepancy between patients' violence experiences (VE) and general practitioners' (GP) awareness is reported. The number of GP visits by victims is of interest. Using data of the nationally representative German Health Interview and Examination Survey for Adults (DEGS1), associations between the prevalence of ≥1 recent VE (last 12 months) and the number of GP contacts were analyzed with respect to age, gender, socio-economic status, and health conditions. The DEGS1 dataset comprised persons aged 18 to 64 years (n = 5938). The prevalence of a recent VE was 20.7%. Compared to non-victims, VE victims visited their GP significantly more often in the preceding 12 months (3.47 vs. 2.87, p < 0.001), which increased markedly in those who were strongly impaired by a recent physical VE (3.55 GP visits) or psychological VE (4.24). The high frequency of GP contacts in VE victims constitutes opportunities to professionally support this vulnerable patient group and underlines the necessity for GPs to integrate VE as a bio-psycho-social problem in a holistic treatment approach.

Small Changes in Patient Arrival and Consultation Times Have Large Effects on Patients' Waiting Times: Simulation Analyses for Primary Care.

(1) Background: Workflows are a daily challenge in general practices. The desired smooth work processes and patient flows are not easy to achieve. This study uses an operational research approach to illustrate the general effects of patient arrival and consultation times on waiting times. (2) Methods: Stochastic simulations were used to model complex daily workflows of general practice. Following classical queuing models, patient arrivals, queuing discipline, and physician consultation times are three key factors influencing work processes. (3) Results: In the first scenario, with patients arriving every 7.6 min and random consultation times, the individual patients' maximum waiting time increased to more than 200 min. The second scenario with random patient arrivals and random consultation times increased the average waiting time by up to 30 min compared to patients arriving on schedule. A busy morning session based on the second scenario was investigated to compare two alternative intervention strategies to reduce subsequent waiting times. Both could reduce waiting times by a multiple for each minute of reduced consultation time. (4) Conclusions: Aiming to improve family physicians' awareness of strategies for improving workflows, this simulation study illustrates the effects of strategies that address consultation times and patient arrivals.
