Associations of accelerometer-based sedentary bouts with adiposity markers among German adults - results from a cross-sectional study.

BACKGROUND: Long periods of uninterrupted sitting, i.e., sedentary bouts, and their relationship with adverse health outcomes have moved into focus of public health recommendations. However, evidence on associations between sedentary bouts and adiposity markers is limited. Our aim was to investigate associations of the daily number of sedentary bouts with waist circumference (WC) and body mass index (BMI) in a sample of middle-aged to older adults. METHODS: In this cross-sectional study, data were collected from three different studies that took place in the area of Greifswald, Northern Germany, between 2012 and 2018. In total, 460 adults from the general population aged 40 to 75 years and without known cardiovascular disease wore tri-axial accelerometers (ActiGraph Model GT3X+, Pensacola, FL) on the hip for seven consecutive days. A wear time of ≥ 10 h on ≥ 4 days was required for analyses. WC (cm) and BMI (kg m- 2) were measured in a standardized way. Separate multilevel mixed-effects linear regression analyses were used to investigate associations of sedentary bouts (1 to 10 min, >10 to 30 min, and >30 min) with WC and BMI. Models were adjusted for potential confounders including sex, age, school education, employment, current smoking, season of data collection, and composition of accelerometer-based time use. RESULTS: Participants (66% females) were on average 57.1 (standard deviation, SD 8.5) years old and 36% had a school education >10 years. The mean number of sedentary bouts per day was 95.1 (SD 25.0) for 1-to-10-minute bouts, 13.3 (SD 3.4) for >10-to-30-minute bouts and 3.5 (SD 1.9) for >30-minute bouts. Mean WC was 91.1 cm (SD 12.3) and mean BMI was 26.9 kg m- 2 (SD 3.8). The daily number of 1-to-10-minute bouts was inversely associated with BMI (b = -0.027; p = 0.047) and the daily number of >30-minute bouts was positively associated with WC (b = 0.330; p = 0.001). All other associations were not statistically significant. CONCLUSION: The findings provide some evidence on favourable associations of short sedentary bouts as well as unfavourable associations of long sedentary bouts with adiposity markers. Our results may contribute to a growing body of literature that can help to define public health recommendations for interrupting prolonged sedentary periods.

Population-Based, Spatial Analysis of Specialised Ambulatory Palliative Care in Mecklenburg-Western Pomerania, Germany, on the Basis of Reimbursement Data.

In rural areas, healthcare providers, patients and relatives have to cover long distances. For specialised ambulatory palliative care (SAPV), a supply radius of max. 30 km is recommended. The aim of this study was to analyse whether there are regional disparities in the supply of SAPV and whether it is associated with the distance between the SAPV team's site and the patient's location. Therefore, anonymised data of the Association of Statutory Health Insurance Physicians of the Federal State of Mecklenburg-Western Pomerania (M-V) were retrospectively analysed for the period of 2014-2017. Identification as a palliative patient was based on palliative-specific items from the ambulatory reimbursement catalogue. In total, 6940 SAPV patients were identified; thereof, 48.9% female. The mean age was 73.3 years. For 28.3% of the identified SAPV patients (n = 1961), the SAPV teams had a travel distance of >30 km. With increasing distance, the average number of treatment days per patient increased. It was found that there are regional disparities in the provision of SAPV services in M-V and that local structures have an important impact on regional supply patterns. The distance between the SAPV team's site and the patient's location is not the only determining factor; other causes must be considered.

[Differences in Billing Patterns Between GPs and Pediatricians Using Early Diagnostics in Children and Adolescents as an Example: Analysis of Nationwide Data from Statutory Health Insurance Physicians]. / Kompensation von Leistungen zwischen Hausärzten und Kinder- und Jugendmedizinern am Beispiel der Früherkennungsuntersuchungen bei Kindern und Jugendlichen ­ Analyse von bundesweiten KBV-Daten.

BACKGROUND: Despite a 13.1% increase in the number of pediatricians between 2011 - 2020, the capacity of pediatric care has largely stagnated. This is due to increasing flexibility in working hours and a declining willingness of doctors to establish practices. In addition, there is an imbalance in the distribution of pediatric medical care capacities. While metropolitan areas are often characterized by oversupply, there is an increasing shortage of pediatricians, especially in rural areas. As a result, general practitioners in rural areas are increasingly taking over part of pediatric care. We quantify this compensation effect using the example of examinations of general health and normal child development (U1-U9). METHODS: Basis of the analysis was the Doctors' Fee Scale within the Statutory Health Insurance Scheme (Einheitlicher Bewertungsmaßstab, EBM) from 2015 (4th quarter). Nationwide data from the National Association of Statutory Health Insurance Physicians (KBV) for general practitioners and pediatricians from 2015 was evaluated. In the first step, the EBM was used to determine the potential overlap of services between the two groups of doctors. The actual compensation between the groups was quantified using general health and normal child development as an example. RESULTS: In section 1.7.1 (early detection of diseases in children) of the EBM, there is a list of 16 options for services that can be billed (fee schedule positions, GOP) by general practitioners and pediatricians. This particularly includes child examinations U1 to U9. The analysis of the national data of the KBV for the early detection of diseases in children showed significant differences between rural and urban regions in the billing procedure. Nationwide, general practitioners billed 6.6% of the services in the area of early detection of diseases in children in 2015. In rural regions this share was 23% compared to 3.6% in urban regions. The analysis of the nationwide data showed that the proportion of services billed by general practitioners was higher in rural regions than in urban regions. CONCLUSION: The EBM allows billing of services by both general practitioners and pediatricians, especially in the area of general GOP across all medical groups. The national billing data of the KBV shows that general practitioners in rural regions bill more services from the corresponding sections than in urban regions.

Comparison of survival between patients receiving general outpatient palliative care and patients receiving other palliative care - analysis of data of a statutory health insurance data.

BACKGROUND: The care of palliative patients takes place as non-specialized and specialized care, in outpatient and inpatient settings. However, palliative care is largely provided as General Outpatient Palliative Care (GOPC). This study aimed to investigate whether the survival curves of GOPC patients differed from those of the more intensive palliative care modalities and whether GOPC palliative care was appropriate in terms of timing. METHODS: The study is based on claims data from a large statutory health insurance. The analysis included 4177 patients who received palliative care starting in 2015 and who were fully insured 1 year before and 1 year after palliative care or until death. The probability of survival was observed for 12 months. Patients were classified into group A, which consisted of patients who received palliative care only with GOPC, and group B including patients who received inpatient or specialized outpatient palliative care. Group A was further divided into two subgroups. Patients who received GOPC on only 1 day were assigned to subgroup A1, and patients who received GOPC on two or more days were assigned to subgroup A2. The survival analysis was carried out using Kaplan-Meier curves. The median survival times were compared with the log-rank test. RESULTS: The survival curves differed between groups A and B, except in the first quartile of the survival distribution. The median survival was significantly longer in group A (137 days, n = 2763) than in group B (47 days, n = 1424, p < 0.0001) and shorter in group A1 (35 days, n = 986) than in group A2 (217 days, n = 1767, p < 0.0001). The survival rate during the 12-month follow-up was higher in group A (42%) than in group B (11%) and lower in group A1 (38%) than in group A2 (44%). CONCLUSIONS: The results of the analysis revealed that patients who received the first palliative care shortly before death suspected insufficient care, especially patients who received GOPC for only 1 day and no further palliative care until death or 12-month follow-up. Palliative care should start as early as necessary and be continuous until the end of life.

Continuity in palliative care - analysis of intersectoral palliative care based on routine data of a statutory health insurance.

BACKGROUND: The goal of palliative care is to prevent and alleviate a suffering of incurable ill patients. A continuous intersectoral palliative care is important. The aim of this study is to analyse the continuity of palliative care, particularly the time gaps between hospital discharge and subsequent palliative care as well as the timing of the last palliative care before the patient's death. METHODS: The analysis was based on claims data from a large statutory health insurance. Patients who received their first palliative care in 2015 were included. The course of palliative care was followed for 12 months. Time intervals between discharge from hospital and first subsequent palliative care as well as between last palliative care and death were analysed. The continuity in palliative care was defined as an interval of less than 14 days between palliative care. Data were analysed using descriptive statistics and Chi-Square. RESULTS: In 2015, 4177 patients with first palliative care were identified in the catchment area of the statutory health insurance. After general inpatient palliative care, 415 patients were transferred to subsequent palliative care, of these 67.7% (n = 281) received subsequent care within 14 days. After a stay in a palliative care ward, 124 patients received subsequent palliative care, of these 75.0% (n = 93) within 14 days. Altogether, 147 discharges did not receive subsequent palliative care. During the 12-months follow-up period, 2866 (68.7%) patients died, of these 78.7% (n = 2256) received palliative care within the last 2 weeks of life. Of these, 1223 patients received general ambulatory palliative care, 631 patients received specialised ambulatory palliative care, 313 patients received their last palliative care at a hospital and 89 patients received it in a hospice. CONCLUSIONS: The majority of the palliative care patients received continuous palliative care. However, there are some patients who did not receive continuous palliative care. After inpatient palliative care, each patient should receive a discharge management for a continuation of palliative care. Readmissions of patients after discharge from inpatients palliative care can be an indication for a lack of support in the ambulatory health care setting and for an insufficient discharge management. Palliative care training and possibilities for palliative care consultations by specialists should strengthen the GPs in palliative care.

Not Just the Demographic Change--The Impact of Trends in Risk Factor Prevalences on the Prediction of Future Cases of Myocardial Infarction.

BACKGROUND: Previous predictions of population morbidity consider demographic changes only. To model future morbidity, however, changes in prevalences of risk factors should be considered. We calculated the number of incident cases of first myocardial infarction (MI) in Mecklenburg-Western Pomerania in 2017 considering the effects of demographic changes and trends in the prevalences of major risk factors simultaneously. METHODS: Data basis of the analysis were two population-based cohorts of the German Study of Health in Pomerania (SHIP-baseline [1997-2001] and the 5-year follow-up and SHIP-Trend-baseline [2008-2011] respectively). SHIP-baseline data were used to calculate the initial coefficients for major risk factors for MI with a Poisson regression model. The dependent variable was the number of incident cases of MI between SHIP-baseline and SHIP-5-year follow-up. Explanatory variables were sex, age, a validated diagnosis of hypertension and/or diabetes, smoking, waist circumference (WC), increased blood levels of triglycerides (TG) and low-density-lipoprotein cholesterol (LDL), and low blood levels of high-density-lipoprotein cholesterol (HDL). Applying the coefficients determined for SHIP baseline to risk factor prevalences, derived from the new cohort SHIP-Trend together with population forecast data, we calculated the projected number of incident cases of MI in 2017. RESULTS: Except for WC and smoking in females, prevalences of risk factors in SHIP-Trend-baseline were lower compared to SHIP-baseline. Based on demographic changes only, the calculated incidence of MI for 2017 compared to the reference year 2006 yields an increase of MI (males: +11.5%, females: +8.0%). However, a decrease of MI (males: -23.7%, females: -17.1%) is shown considering the changes in the prevalences of risk factors in the projection. CONCLUSIONS: The predicted number of incident cases of MI shows large differences between models with and without considering changes in the prevalences of major risk factors. Hence, the prediction of incident MI should preferably not only be based on demographic changes.

[Prognosis of population-related morbidity for common cancers in Germany--Effects on health care]. / Deutschlandweite, regionalisierte Prognose der bevölkerungsbezogenen Morbidität für häufige Krebserkrankungen--Auswirkungen auf die Versorgung.

INTRODUCTION: The demand for outpatient and inpatient oncology care will rise in the next years. In this analysis, the number of new cases and the prevalence in 2020, the number of hospital days, types of treatment, sickness costs, and the number of oncology specialists are prognosed. METHODS: Projections of incidence and prevalence of cancer overall and of the three most common cancers were conducted with data from the German Population-Based Cancer Registries and from the German Federal Statistics Office. The average number of hospital days was extrapolated until 2020 on the basis of these population projections. Outpatient care was analyzed with billing data obtained from the WINHO. Projections of sickness costs in 2020 were calculated based on data from the German Federal Statistics Office under the assumption that cost per prevalent case remains constant within a given age group over the projection period. Numbers of specialists in hematology and oncology were taken from the database of the Association of Statutory Health Insurance Physicians. These forecasts are based on a series of assumptions. RESULTS: The number of new cancer cases will increase by about 67,000 cases until 2020 (reference year 2008). Prevalent cases will increase by about 176,000 cases. The needed number of hospital days will increase about 13% to 15.513 million days in 2020. An increase of 30% in cytoreductive and 23% in chemotherapy treatment of lung cancer was shown between 2008 and 2011. The number of contracted doctors with focus in hematology and oncology has increased in 2011 compared to 2005. Between 2002 and 2008, sickness costs increased by 52% in the outpatient sector and by 31% in the inpatient sector. In 2020, the increase of sickness costs is expected to reach about 1.7 billion EUR/year. CONCLUSIONS: Due to the increase of incident and prevalent cancer cases, the number of hospital days and sickness costs will increase. The results of the analyses show an increase of medical care services in the outpatient sector.

Characteristics associated with non-participation in 7-day accelerometry.

OBJECTIVE: To assess levels of physical activity the use of objective physical activity measures like accelerometers is promising. We investigated characteristics associated with non-participation in accelerometry within an apparently healthy sample. METHODS: Among German participants of a cardiovascular examination program (CEP; 2012-2013), 470 participants aged 40-75 years were invited to wear an accelerometer for 7 days. We used multivariate logistic regression to estimate the association between non-participation and the following characteristics of participants: sex, age, education, smoking, setting of recruitment for the CEP (general medical practices, job agencies, statutory health insurance), self-reported general health, and objective health criteria such as cardiorespiratory fitness and absolute number of cardiometabolic risk factors (elevated waist circumference, blood pressure, triglycerides, blood glucose, and reduced high-density lipoprotein). Subsequently, we stratified this analysis by sex. RESULTS: Among all invited individuals, N = 235 (60.0% women) gave consent to participate in accelerometry. Women were more likely to decline participation (odds ratio, 1.7; 95% confidence interval, 1.1-2.7) compared to men. Stratified analyses revealed the absolute number of risk factors as predictor of non-participation for men (1.4; 1.01-2.0), while there was no predictor found in women. CONCLUSION: We found a self-selection bias in participation in accelerometry. Women declined study participation more likely than men. The number of cardiometabolic risk factors decreased compliance only in men. Future studies should consider strategies to reduce this bias.

Changes in blood pressure in patients with hypertension in the context of delegated GP-home visits: a prospective implementation study.

BACKGROUND: The AGnES-concept (GP-supporting, community-based, e-health-assisted, systemic intervention) includes the delegation of general practitioner (GP)-home visits to qualified practice assistants, especially in underserved areas. Most visited patients were elderly, multimorbid patients with limited mobility. We analyzed a subgroup of hypertension patients to assess the proportion of patients with controlled hypertension, the number of patients that changed between different categories of blood pressure during the project, and to identify possible determinants for these changes. MATERIALS AND METHODS: Eligible patients were selected by the participating GPs. Hypertensive patients with at least two blood pressure measurements were included. Two-level mixed-effects multiple binary logistic regression analyses were conducted to evaluate possible determinants for the found effects. RESULTS: Overall, 776 patients (mean age 79.2 years; SD 8.1 years; range 38-98 years) were included in the analysis. During the project, the mean values for systolic (from 136.1 to 131.0 mmHg, P<0.0001) and diastolic (from 77.0 to 75.7 mmHg, P=0.0026) blood pressure decreased. In 26.0% of the patients there was a change from hypertensive blood pressure values to normotensive values and vice versa in 14.3% (P<0.0001). Multilevel regression models did not show single elements of the complex intervention as determinants for changing to normotensive blood pressure values. CONCLUSION: Although the study was conducted under real life conditions and therefore had some methodological limitations, the delegation of home visits to qualified practice assistants may have had a positive influence on changes of blood pressure with elderly hypertension patients. The study population represents a relevant population for medical care, which might benefit from the implementation of the AGnES-concept.

Outcomes and prognostic factors in gallbladder cancer: a single-centre experience.

INTRODUCTION: Gallbladder cancer is the most common malignant tumour of the biliary system with an extraordinarily poor prognosis. In this study, we retrospectively evaluated forty-two patients with histologically proven gallbladder cancer. PATIENTS AND METHODS: Estimated survival rates were calculated by the Kaplan-Meier method, and differences were assessed using the logrank test. The GKR (combined registry of cancer) and demographic data were used to gain information on community cancer statistics. RESULTS: In this study, patients with metastases showed poorer survival rates. Furthermore, the survival was significantly better in patients with R0 resections, smaller tumour sizes and without lymph node infiltration. T stage, M stage and R stage were independent prognostic parameters. Sex and age had no significant effect on survival. Also, we found that patients with incidental gallbladder cancer and those with cholecystolithiasis showed significantly better survival rates. Demographic analyses of the study group confirmed a high coverage of our institution for incident cases in our catchment area and no significant regional deviations from the expected incidence of gallbladder cancer. CONCLUSION: Despite differences in the incidence in different geographical areas, gallbladder cancer appears to be fairly normally distributed in Western Pomerania, a predominantly rural area of Northeastern Germany. Coverage of incident cases in our catchment area was high. T stage, M stage and R stage were independent prognostic factors in our study. We conclude that, whenever possible, an R0 resection should be the surgical goal in all patients staged resectable before surgery, but heroic resections in patients with highly advanced cancer disease or severe accompanying non-tumour diseases are not warranted.

Detection of drug related problems in an interdisciplinary health care model for rural areas in Germany.

OBJECTIVE: The disparity between an increasing complexity of patients' treatment and the declining number of general practitioners (GP) require action. The AGnES-concept (general practitioner-relieving, community-based, e-health assisted, systemic intervention) is based on the delegation of original physician-activities to qualified AGnES-practice assistants. Purposes of AGnES part 1 were to determine the feasibility of community-based home medication reviews (HMR) and the establishment of a health professional network to identify drug related problems (DRP) in the domicile of elderly patients. Two consecutive studies (AGNES 2 + 3) were conducted to implement HMR. SETTING: General practices on the isle of Rugia in Mecklenburg-Western Pomerania, a German rural area. Patients who receive regular home visits by their GP were addressed. METHOD: Study-instruments for the feasibility study (AGnES 1) were designed by an expert panel and modified for the implementation (AGnES 2 + 3) studies. HMR were conducted by additionally qualified AGnES-practice assistants regarding DRP like drug-drug interaction (DDI), adverse drug reactions (ADR), and compliance. DRP-selection was inspired by the coding system Pi-Doc. Pharmacists checked DRP and intervened, if necessary. 18 (AGnES 1) and 60 (AGnES 2 + 3) geriatric patients received a minimum of two home visits by an AGnES-practice assistant. MAIN OUTCOME MEASURE: Feasibility was assessed by patients' satisfaction with care provided by the AGnES-practice assistant. For implementation reported DRP and the conducted interventions were evaluated. RESULTS: During AGnES 1 a documentation sheet was developed and tested. 56 potential DDI were identified. 37 of 112 drugs which caused potential interactions were attributed to OTC medication and food components. 84% of respondents judged the systematic evaluation of their pharmacotherapy as helpful. During AGnES 2 + 3 local pharmacists identified DDIs in 45% of patients. Seven patients (11.6%) reported at least one ADR attributable to their current medication. Those patients who received a second HMR (n = 29) during AGnES 2 + 3 rated the HMR as reasonable 65.5% (n = 19), and partly reasonable 24.1% (n = 7). CONCLUSIONS: By comprehensive HMR conducted by AGnES-practice assistants in delegation of the patients' GPs in cooperation with local pharmacists we could identify a considerable prevalence of DRP under real-life conditions. Further studies should recruit more participants including a control group with usual care.

AGnES: supporting general practitioners with qualified medical practice personnel: model project evaluation regarding quality and acceptance.

BACKGROUND: The German AGnES (community-based, e-health-assisted systemic support for primary care) project allows general practitioners (GPs) to delegate certain elements of medical care, including house calls, to qualified AGnES employees and thereby provide primary care to a larger number of patients. AGnES projects of various types have been carried out in a number of German federal states from 2005 onward. In this article, an evaluation of the AGnES projects to date is presented. METHODS: Patient data (age, sex, diagnoses, level of care, mobility, etc.) and each of the specific activities carried out in the AGnES framework were documented with standardized computer-based instruments. The GPs, AGnES employees, and patients also underwent standardized interviews. The acceptance of the AGnES project, competence of the AGnES employees, and quality of medical care within the projects were evaluated. The participating GPs themselves assessed the quality of medical care. RESULTS: By July 8, 2008, 8386 house calls on a total of 1486 patients had been made within the framework of the AGnES projects. The evaluation revealed a high degree of acceptance of the project among the participating GPs, AGnES employees, and patients. The GPs considered the quality of medical care within the AGnES project to be good for the vast majority of patients. CONCLUSION: Structural redundancy is avoided by directly placing the AGnES employees in the general practitioners' practices. Based on the results of the AGnES projects, the law in Germany has now been amended to enable implementation of the AGnES project in the regular health care system from January 2009 onward. The next steps to be taken are the establishment of adequate reimbursement within the catalog of the statutory health insurance scheme and a detailed definition of the required qualifications.
