A Framework for Measuring Neighborhood Walkability for Older Adults-A Delphi Consensus Study.

While mobility in older age is of crucial importance for health and well-being, it is worth noting that currently, there is no German language framework for measuring walkability for older adults that also considers the functional status of a person. Therefore, we combined the results of an expert workshop, a literature review, and a Delphi consensus survey. Through this, we identified and rated indicators relevant for walkability for older adults, additionally focusing on their functional status. The expert workshop and the review led to an extensive list of potential indicators, which we hope will be useful in future research. Those indicators were then adapted and rated in a three-stage Delphi expert survey. A fourth additional Delphi round was conducted to assess the relevance of each indicator for the different frailty levels, namely "robust," "pre-frail," and "frail." Between 20 and 28 experts participated in each round of the Delphi survey. The Delphi process resulted in a list of 72 indicators deemed relevant for walkability in older age groups, grouped into three main categories: "Built environment and transport infrastructure," "Accessibility and meeting places," and "Attractiveness and sense of security." For 35 of those indicators, it was suggested that functional status should be additionally considered. This framework represents a significant step forward in comprehensively covering indicators for subjective and objective walkability in older age, while also incorporating aspects of functioning relevant to older adults. It would be beneficial to test and apply the indicator set in a community setting.

Effects of heat and personal protective equipment on thermal strain in healthcare workers: part B-application of wearable sensors to observe heat strain among healthcare workers under controlled conditions.

PURPOSE: As climate change accelerates, healthcare workers (HCW) are expected to be more frequently exposed to heat at work. Heat stress can be exacerbated by physical activity and unfavorable working requirements, such as wearing personal protective equipment (PPE). Thus, understanding its potential negative effects on HCW´s health and working performance is becoming crucial. Using wearable sensors, this study investigated the physiological effects of heat stress due to HCW-related activities. METHODS: Eighteen participants performed four experimental sessions in a controlled climatic environment following a standardized protocol. The conditions were (a) 22 °C, (b) 22 °C and PPE, (c) 27 °C and (d) 27 °C and PPE. An ear sensor (body temperature, heart rate) and a skin sensor (skin temperature) were used to record the participants´ physiological parameters. RESULTS: Heat and PPE had a significant effect on the measured physiological parameters. When wearing PPE, the median participants' body temperature was 0.1 °C higher compared to not wearing PPE. At 27 °C, the median body temperature was 0.5 °C higher than at 22 °C. For median skin temperature, wearing PPE resulted in a 0.4 °C increase and higher temperatures in a 1.0 °C increase. An increase in median heart rate was also observed for PPE (+ 2/min) and heat (+ 3/min). CONCLUSION: Long-term health and productivity risks can be further aggravated by the predicted temperature rise due to climate change. Further physiological studies with a well-designed intervention are needed to strengthen the evidence for developing comprehensive policies to protect workers in the healthcare sector.

Accessibility to specialist palliative care services in Germany: a geographical network analysis.

BACKGROUND: The need for palliative care will increase over the next years because of the rise in deaths from chronic illness and demographic changes. The provision of specialist palliative care (SPC) in Germany (palliative care units (PCU), specialist palliative home care (SPHC) teams and palliative care advisory (PCA) teams) has been expanded in recent years. Despite the increasing availability, there is still insufficient coverage with long travel times. The aim was to describe the spatial distribution of SPC services in Germany, to calculate the potential accessibility of facilities and to assess potential spatial under-provision. METHODS: Retrospective cross-sectional study with regional analysis of SPC services in Germany. Addresses of SPC services registered online were geocoded, accessibility and network analyses were conducted, and proportion of the population living up to 60 minutes driving time were calculated. RESULTS: A total of 673 facilities were included. Their distribution is heterogeneous with every fourth of the 401 districts (110/401; 27.4%) lacking a SPC service. In half of the area of Germany the existing PCU and SPHC teams are within reach of 30 minutes, with nearly 90% of the population living there. Hospitals providing PCA teams can be reached within 30 minutes in 17% of the total area with provision for 43% of the population. CONCLUSIONS: A high coverage of SPHC teams and PCU indicates a good spatial distribution in Germany but no complete adequate provision of SPC services, especially for PCA teams. There is a persistent need for further implementation of hospital PCA teams.

[Mapping Regional Differences in Infection Rates for the Coronavirus (COVID-19): Results of a Bayesian Approach to Administrative Districts of Bavaria]. / Kartografische Darstellung regionaler Unterschiede der Infektionsraten beim Coronavirus (COVID-19): Ergebnisse einer bayesianischen Glättung über Landkreise Bayerns.

BACKGROUND: Since the beginning of the COVID-19 pandemic, thematic maps showing the spread of the disease have been of great public interest. From the perspective of risk communication, those maps can be problematic, since random variation or extreme values may occur and cover up the actual regional patterns. One potential solution is applying spatial smoothing methods. The aim of this study was to show changes in incidence ratios over time in Bavarian districts using spatially smoothed maps. METHODS: Data on SARS-CoV-2 were provided by the Bavarian Health and Food Safety Authority on 29.10.2021 and 17.02.2022. The demographic data per district are derived from the Statistical Report of the Bavarian State Office for Statistics for 2019. Four age groups per sex (<18, 18-29, 30-64,>64 years) divided into 16 time periods (01/28/2020 to 12/31/2021) were included. Maps show standardized incidence ratios (SIR) spatially smoothed by Bayesian hierarchical modelling. RESULTS: The SIR varied remarkably between districts. Variations occurred for each time period, showing changing regional patterns over time. CONCLUSION: Smoothed health maps are suitable for showing trends in incidence ratios over time for COVID-19 in Bavaria and offer the advantage over traditional maps in giving more realistic estimates by including neighborhood relationships. The methodological approach can be seen as a first step to explain the regional heterogeneity in the pandemic, and to support improved risk communication.

Identification of relevant performance indicators for district healthcare systems in Ethiopia: a systematic review and expert opinion.

PURPOSE: To identify potential performance indicators relevant for district healthcare systems of Ethiopia. DATA SOURCES: Public Library of Medicine and Agency for Healthcare Research and Quality of the United States of America, Organization for Economic Cooperation and Development Library and Google Scholar were searched. STUDY SELECTION: Expert opinions, policy documents, literature reviews, process evaluations and observational studies published between 1990 and 2015 were considered for inclusion. Participants were national- and local-healthcare systems. The phenomenon of interest was the performance of healthcare systems. The Joanna Briggs Institute tools were adapted and used for critical appraisal of records. DATA EXTRACTION: Indicators of performance were extracted from included records and summarized in a narrative form. Then, experts rated the relevance of the indicators. Relevance of an indicator is its agreement with priority health objectives at the national and district level in Ethiopia. RESULTS OF DATA SYNTHESIS: A total of 11 206 titles were identified. Finally, 22 full text records were qualitatively synthesized. Experts rated 39 out of 152 (25.7%) performance indicators identified from the literature to be relevant for district healthcare systems in Ethiopia. For example, access to primary healthcare, tuberculosis (TB) treatment rate and infant mortality rate were found to be relevant. CONCLUSION: Decision-makers in Ethiopia and potentially in other low-income countries can use multiple relevant indicators to measure the performance of district healthcare systems. Further research is needed to test the validity of the indicators.

[Geographic methods for health monitoring]. / Geografische Ansätze in der Gesundheitsberichterstattung.

The interest in using geographic methods for health monitoring has grown strongly over the last two decades. Through these methods, analysis and visualization of health data can be more focused and target-group specific. The application in health monitoring is possible mostly due to broader technical possibilities and more available datasets. In this article, we show which geographic aspects are adapted in health monitoring at different levels (federal, state, municipality).For example, at the federal level, surveillance methods are used; at the state level health atlases are created; and on the municipality level geographic analyses are performed for possible public health interventions.Methods range from simple maps on different levels of aggregation to more complex methods like space-temporal visualization or spatial-smoothing methods. While the technical possibilities are in place, a broader implementation of geographic methods is mostly hindered by missing data access to small-area information and data protection policies. Better access to data could especially improve the possibility for geographic methods in health monitoring and could inform the population and decision makers to inform and improve population health or healthcare.

Administrators, health service providers, and consumers perspectives of functions of district health-care systems in Oromia region, Ethiopia: A qualitative study.

The practice of functions of district health-care systems in Ethiopia is not clear. The aim of this study was to investigate the perspectives of administrators, health service providers, and health-care consumers regarding functions of district health-care systems as currently practiced. Grounded theory approach was applied using interviews and desk review of documents. This study was set up in Oromia National Regional State, Ethiopia. Inductive analysis of interviews was done. Interviews and document reviews were mirrored. Eleven functions of district health-care systems emerged in this study organized by level with relationships and commonality of few activities. The 11 functions of district health-care systems were creating capacity of health centers and health professionals for the provision of health care; creating access for the provision of health care; ensuring equitable access to health care; regulation of private health-care providers; disaster preparedness; monitoring risk factors and diseases in the district; provision of health promotive, preventive, and curative health care for communicable diseases and maternal health conditions; monitoring intermediate outcomes of care; developing capacity of health post and villagers toward demand creation for health care; provision of maternal and child health services; and helping health posts in reaching mothers and sick individuals.

[Different Regions, Differently Insured Populations? Socio-demographic and Health-related Differences Between Insurance Funds]. / Verschiedene Regionen, verschiedene Versichertenpopulationen? Soziodemografische und gesundheitsbezogene Unterschiede zwischen Krankenkassen.

Objectives: Analyses of health insurance claims data are getting more important in public health and health services research. Since there are several different health insurance funds in Germany, the specific characteristics of regional and socio-demographic population covered by a single fund has to be considered. The aim of this study is to evaluate the differences in socio-demographic and health-related variables between health insurance funds. Methods: This study is based on the GEDA-Study 2009 and 2010, 2 representative cross-sectional telephone surveys (n=42 534). We included socio-economic factors as well as information on area of residence and health-related variables to health status, health behavior and cardiovascular diseases. Results: There are fewer privately insured persons in the eastern regions of Germany. Insurants of the public health insurances have a lower socio-economic status and many have a migration background. Similar results can be found for smoking, obesity and cardiovascular factors. These differences between funds were found in many regional analyses. Conclusions: Especially differences in socio-economic factors are constant between insurance funds and regions. Therefore, the results show that analyses of one single health insurance fund cannot be generalized to the whole population. To ensure precise estimates on health services, morbidity or quality monitoring, we need data sets that integrate more funds.

Does charge-free screening improve detection of gestational diabetes in women from deprived areas: a cross-sectional study.

BACKGROUND: Gestational diabetes mellitus (GDM) occurs in 2-6 % of all pregnancies. We investigated whether area level deprivation is associated with a higher risk for GDM and whether GDM detection rates in deprived regions changed after the introduction of charge-free GDM screening in Germany in 2012. METHODS: We analyzed population-based data from Bavaria, Germany, comprising n = 587,621 deliveries in obstetric units between 2008 and 2014. Area level deprivation was assessed municipality-based using the Bavarian Index of Multiple Deprivation (BIMD), divided into quintiles and assigned to each mother based on her residential address. We estimated annual odds ratios (ORs) for GDM diagnosis by BIMD quintile with adjustment for maternal obesity, maternal age, migration background and single mother status. RESULTS: Women from the most deprived regions were less likely to be diagnosed with GDM before introduction of charge-free GDM screening (OR = 0.76 [95 % confidence interval: 0.66, 0.86] compared to least deprived areas), in 2008. In contrast, high area level deprivation was associated with significantly increased risk of GDM diagnosis in 2013 (OR [95 % confidence interval] = 1.15 [1.02, 1.29]). The OR was also elevated, although not significantly, in 2014 (OR [95 % confidence interval] = 1.05 [0.93, 1.18]). CONCLUSIONS: The prevalence of GDM seems to have been underreported in women from highly deprived areas before introduction of the charge-free GDM screening in Germany. In fact, women living in deprived regions seem to have an increased risk for GDM and may profit from access to charge-free GDM screening.

Continuity of care in the ambulatory sector and hospital admissions among patients with heart failure in Germany.

BACKGROUND: Heart failure is one of the most cost-intensive chronic diseases and the most common cause of hospitalization. More than 60% of the treatment costs of heart failure are incurred in the inpatient sector in Germany. However, hospital admissions due to heart failure are considered to be potentially avoidable through effective and continuous ambulatory care. Our aim is to examine whether continuity in ambulatory care is associated with hospitalizations due to heart failure. METHODS: Using insurance claims data from Germany's biggest statutory health insurance company, we defined three measures of continuity of care: Continuity of Care Index (COCI), Usual Provider Index (UPC) and the Sequential Continuity Index (SECON). We analyzed whether these measures are associated with hospitalization due to heart failure using separate logistic regression models. We controlled for a wide range of covariates such as sex, age and the Charlson comorbidity index. RESULTS: Data of 382 118 heart failure patients were included in the analyses. Index values range from 0.77 to 0.89. Results of logistic regression analyses indicate that the continuity indices COCI, UPC and SECON based on visits to general practitioners (GPs), cardiologists and internists are negatively associated with the probability of hospitalization whereas of the continuity indices based on GP visits only SECON is significantly associated with hospitalization. CONCLUSION: The results indicate that the overall continuity in the ambulatory sector is high for heart failure patients in Germany. Public policy should, nevertheless, focus on increasing sequential continuity of specialist and generalist ambulatory care as this was found to be significantly associated with a reduced likelihood of hospitalization.

Overutilization of ambulatory medical care in the elderly German population?--An empirical study based on national insurance claims data and a review of foreign studies.

BACKGROUND: By definition, high utilizers receive a large proportion of medical services and produce relatively high costs. The authors report the results of a study on the utilization of ambulatory medical care by the elderly population in Germany in comparison to other OECD countries. Evidence points to an excessive utilization in Germany. It is important to document these utilization figures and compare them to those in other countries since the healthcare system in Germany stopped recording ambulatory healthcare utilization figures in 2008. METHODS: The study is based on the claims data of all insurants aged ≥ 65 of a statutory health insurance company in Germany (n = 123,224). Utilization was analyzed by the number of contacts with physicians in ambulatory medical care and by the number of different practices contacted over one year. Criteria for frequent attendance were ≥ 50 contacts with practices or contacts with ≥ 10 different practices or ≥ 3 practices of the same discipline per year. Descriptive statistical analysis and logistic regression were applied. Morbidity was analyzed by prevalence and relative risk for frequent attendance for 46 chronic diseases. RESULTS: Nineteen percent of the elderly were identified as high utilizers, corresponding to approximately 3.5 million elderly people in Germany. Two main types were identified. One type has many contacts with practices, belongs to the oldest age group, suffers from severe somatic diseases and multimorbidity, and/or is dependent on long-term care. The other type contacts large numbers of practices, consists of younger elderly who often suffer from psychiatric and/or psychosomatic complaints, and is less frequently multimorbid and/or nursing care dependent. CONCLUSION: We found a very high rate of frequent attendance among the German elderly, which is unique among the OECD countries. Further research should clarify its reasons and if this degree of utilization is beneficial for elderly people.

Age and gender related neuromuscular pattern during trunk flexion-extension in chronic low back pain patients.

BACKGROUND: The root mean square surface electromyographic activity of lumbar extensor muscles during dynamic trunk flexion and extension from standing has repeatedly been recommended to objectively assess muscle function in chronic low back pain patients. However, literature addressing older patients is sparse. This cross sectional study sought to examine differences in neuromuscular activation between age groups (>60 versus 40-60 versus <40 years) and sexes during a standardized trunk flexion-extension task. METHODS: A total of 216 patients (62 older, 84 middle-aged, 70 younger) performed maximum trunk extensions followed by trunk flexion extension testing thereby holding static positions at standing, half, and full trunk flexion. The lumbar extensor muscle activity and 3d-accelerometric signals intended to monitor hip and trunk position angles were recorded from the L5 (multifidus) and T4 (semispinalis thoracis) levels. Permutation ANOVA with bootstrapped confidence intervals were performed to examine for age and gender related differences. Ridge-regressions investigated the impact of physical-functional and psychological variables to the half flexion relaxation ratio (i.e. muscle activity at the half divided by that in maximum flexion position). RESULTS: Maximum back extension torque was slightly but significantly higher in youngest compared to oldest patients if male and females were pooled. Normalized RMS-SEMG revealed highest lumbar extensor muscle activity at standing in the oldest and the female groups. Patients over 60 years showed lowest activity changes from standing to half (increments) and from half to the maximum flexion position (decrements) leading to a significantly lower half flexion relaxation ratio compared to the youngest patients. These oldest patients demonstrated the highest hip and lowest lumbothoracic changes of position angles. Females had higher regional hip and gross trunk ranges of movement compared to males. Lumbothoracic flexion and the muscle activity at standing had a significant impact on the half flexion relaxation ratio. CONCLUSIONS: The neuromuscular activation pattern and the kinematics in this trunk flexion-extension task involving static half flexion position changed according to age and sex. The test has a good potential to discriminate between impaired and unimpaired neuromuscular regulation of back extensors in cLBP patients, thereby allowing the design of more individualized exercise programs.

Institutionalization in incident dementia cases in comparison to age- and sex- matched controls: a 5-year follow-up from Germany.

BACKGROUND: Dementia is a main reason for nursing home admission. Information on institutionalization is often based on studies of limited methodological quality. We aimed to analyze time until nursing home admission since first coding of dementia diagnosis and factors associated with institutionalization in incident dementia patients compared to non-demented controls. METHODS: We analyzed claims data of a German Health insurance company including a cohort of 1,440 patients with a first diagnosis of dementia and 6,988 age- and sex-matched controls aged 65 years and older. The follow-up was up to 5 years. We used Kaplan-Meier analysis for examining time until nursing home admission and cox regression for estimating crude and adjusted Hazard ratios. RESULTS: Dementia patients and controls were on average 78 years and about 55 % were males. The mean time to nursing home admission was 4.0 years in patients with dementia and 4.6 years for controls. After the 5-years observation-period 62.7 % (95 % CI 59.0-66.1) of dementia patients still lived in the community in comparison to 86.2 % (95 % CI 85.2-87.2) of controls. Cox regression models show that the risk for institutionalization is 3.45 (95 % CI 3.05-3.90) times higher in dementia patients in comparison to controls when adjusted for sex, age, and comorbidity. CONCLUSIONS: Our analysis shows a significant influence of dementia on institutionalization in comparison to age- and sex-matched controls, especially in the youngest age groups. Hence, the results add substantial information on the disease progression of dementia and are, therefore, of great importance for health-care as well as long-term care planning.

Multimorbidity and long-term care dependency--a five-year follow-up.

BACKGROUND: Not only single, but also multiple, chronic conditions are becoming the normal situation rather than the exception in the older generation. While many studies show a correlation between multimorbidity and various health outcomes, the long-term effect on care dependency remains unclear. The objective of this study is to follow up a cohort of older adults for 5 years to estimate the impact of multimorbidity on long-term care dependency. METHODS: This study is based on claims data from a German health insurance company. We included 115,203 people (mean age: 71.5 years, 41.4% females). To identify chronic diseases and multimorbidity, we used a defined list of 46 chronic conditions based on ICD-10 codes. Multimorbidity was defined as three or more chronic conditions from this list. The main outcome was "time until long-term care dependency". The follow-up started on January 1st, 2005 and lasted for 5 years until December 31st, 2009. To evaluate differences between those with multimorbidity and those without, we calculated Kaplan-Meier curves and then modeled four distinct Cox proportional hazard regressions including multimorbidity, age and sex, the single chronic conditions, and disease clusters. RESULTS: Mean follow-up was 4.5 years. People with multimorbidity had a higher risk of becoming care dependent (HR: 1.85, CI 1.78-1.92). The conditions with the highest risks for long-term care dependency are Parkinson's disease (HR: 6.40 vs. 2.68) and dementia (HR: 5.70 vs. 2.27). Patients with the multimorbidity pattern "Neuropsychiatric disorders" have a 79% higher risk of care dependency. CONCLUSIONS: The results should form the basis for future health policy decisions on the treatment of patients with multiple chronic diseases and also show the need to introduce new ways of providing long-term care to this population. A health policy focus on chronic care management as well as the development of guidelines for multimorbidity is crucial to secure health services delivery for the older population.

Prevalence of dementia in nursing home and community-dwelling older adults in Germany.

BACKGROUND/AIM: We compared the prevalence of dementia in nursing home residents and community-dwelling older adults . METHODS: Using health insurance claims data for the year 2009, we estimated the prevalence of at least three of four quarters with a diagnosis of dementia in persons aged ≥65 years. RESULTS: Of 213,694 persons aged 65+ years, 4,584 (2.2 %) lived in nursing homes. The prevalence of dementia was 51.8 % (95 % CI 50.4-53.3) in nursing home residents and 2.7 % (95 % CI 2.6-2.8) in community-dwelling elderly. Increasing prevalences with age were found in both sexes in community-dwelling elderly. These trends were not seen in nursing home residents where prevalences were already high for the age group 65-69 years (35.7 % in males and 40.9 % in females, respectively). CONCLUSIONS: More than half of nursing home residents suffer from dementia, which is about 19-fold higher than the prevalence in insured living in the community.

Development of an interprofessional diagnostic toolkit to enhance outside walking gait-related participation of people after stroke in Germany: study protocol of an ongoing multi-methods study.

INTRODUCTION: Persons after stroke experience limitations in activities of daily living even in the chronic phase. Many patients who had a stroke report mobility limitations with loss of social roles such as reduced gait-related participation. International best-practice recommendations for patients who had a stroke include interprofessional diagnostics as a core element for goal setting and intervention planning to improve social participation. Interprofessional diagnostics has not yet been implemented in Germany. METHODS AND ANALYSIS: The aim is to develop an interprofessional diagnostic toolkit. This will be done in a multi-step process: first, an integrative review is conducted to synthesise the literature. Second, the experiences regarding diagnostics and walking outside is captured in focus groups with persons after stroke, relatives and health professionals. Third, a toolkit for the interprofessional diagnostic process of gait-related-participation will be developed based on the results of the previous steps in a future workshop. Fourth, the results of each work package will be integrated into the iterative development process for evaluation and implementation. All steps will be performed in accordance with the respective reporting guidelines. ETHICS AND DISSEMINATION: This study has been approved by the ethics committee at the Ludwig Maximilians University (LMU), Germany and is overseen by LMU-Medical Institutional Review Board. Written informed consent will be obtained from all participants. Results will be disseminated through knowledge exchange with stakeholders and in peer-reviewed journal publications, scientific conferences, formal and informal reports. Stakeholders, patients and providers will be involved in most steps of the development from the beginning, which will facilitate later implementation at a larger scale. TRIAL REGISTRATION NUMBER: German Register Clinical Trials/Deutsches Register Klinischer Studien DRKS00032389.

Choosing a maternity hospital: a matter of travel distance or quality of care?

BACKGROUND: The choice of a hospital should be based on individual need and accessibility. For maternity hospitals, this includes known or expected risk factors, the geographic accessibility and level of care provided by the hospital. This study aims to identify factors influencing hospital choice with the aim to analyze if and how many deliveries are conducted in a risk-appropriate and accessible setting in Bavaria, Germany. METHODS: This is a cross-sectional secondary data analysis based on all first births in Bavaria (2015-18) provided by the Bavarian Quality Assurance Institute for Medical Care. Information on the mother and on the hospital were included. The Bavarian Index of Multiple Deprivation 2010 was used to account for area-level socioeconomic differences. Multiple logistic regression models were used to estimate the strength of association of the predicting factors and to adjust for confounding. RESULTS: We included 195,087 births. Distances to perinatal centers were longer than to other hospitals (16 km vs. 12 km). 10% of women with documented risk pregnancies did not deliver in a perinatal center. Regressions showed that higher age (OR 1.03; 1.02-1.03 95%-CI) and risk pregnancy (OR 1.44; 1.41-1.47 95%-CI) were associated with choosing a perinatal center. The distances travelled show high regional variation with a strong urban-rural divide. CONCLUSION: In a health system with free choice of hospitals, many women chose a hospital close to home and/or according to their risks. However, this is not the case for 10% of mothers, a group that would benefit from more coordinated care.

Utilization of health-related data in the regional context for health service planning in the Federal State of Brandenburg, Germany-a qualitative study.

BACKGROUND: Utilizing regional health data goes hand in hand with challenges: can they be used for health planning, are they applicable to the relevant topics? The study explores current data utilization and needs of stakeholders working in regional health services planning. METHODS: We conducted 16 semi-structured expert-interviews with stakeholders of regional health planning in Brandenburg, a federal state in the north-east of Germany, by telephone or online-meeting tools between 05/2022 and 03/2023. The data were analysed according to qualitative content analysis. RESULTS: Utilization of data sources depends on individual knowledge and personnel resources instead of being guided by standardized procedures. Interviewees primarily use internal data; some use many different platforms, studies and reports. Regional health-related data are used for reliable health planning, to prepare resolutions, draft contracts, but also for events and requests from policy makers or the press. Challenges exist in terms of availability, awareness, and acceptance of the data, perceived applicability, the ability to use it and the utilization itself. Many regional health planners indicated they would appreciate a regional integrated cross-organizational data source if the benefits for health planning outweighed the efforts. DISCUSSION: Actors in health planning primarily utilized their own data for planning; additional data sources are not available or the level of aggregation is too high, not known by them or are often not used due to a lack of time. A standardized regional monitoring would require the definition of indicators as well as the strengthening of cross-sectoral planning.

Differentiating patients admitted primarily due to coronavirus disease 2019 (COVID-19) from those admitted with incidentally detected severe acute respiratory syndrome corona-virus type 2 (SARS-CoV-2) at hospital admission: A cohort analysis of German hospital records.

OBJECTIVE: The number of hospitalized patients with severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) does not differentiate between patients admitted due to coronavirus disease 2019 (COVID-19) (ie, primary cases) and incidental SARS-CoV-2 infection (ie, incidental cases). We developed an adaptable method to distinguish primary cases from incidental cases upon hospital admission. DESIGN: Retrospective cohort study. SETTING: Data were obtained from 3 German tertiary-care hospitals. PATIENTS: The study included patients of all ages who tested positive for SARS-CoV-2 by a standard quantitative reverse-transcription polymerase chain reaction (RT-PCR) assay upon admission between January and June 2022. METHODS: We present 2 distinct models: (1) a point-of-care model that can be used shortly after admission based on a limited range of parameters and (2) a more extended point-of-care model based on parameters that are available within the first 24-48 hours after admission. We used regression and tree-based classification models with internal and external validation. RESULTS: In total, 1,150 patients were included (mean age, 49.5±28.5 years; 46% female; 40% primary cases). Both point-of-care models showed good discrimination with area under the curve (AUC) values of 0.80 and 0.87, respectively. As main predictors, we used admission diagnosis codes (ICD-10-GM), ward of admission, and for the extended model, we included viral load, need for oxygen, leucocyte count, and C-reactive protein. CONCLUSIONS: We propose 2 predictive algorithms based on routine clinical data that differentiate primary COVID-19 from incidental SARS-CoV-2 infection. These algorithms can provide a precise surveillance tool that can contribute to pandemic preparedness. They can easily be modified to be used in future pandemic, epidemic, and endemic situations all over the world.
