Care trajectories of chronically ill older adult patients discharged from hospital:a quantitative cross-sectional study using health insurance claims data

Background For older adults, a good transition from hospital to the primary or long-term care setting can decrease readmissions. This paper presents the 6-month post-discharge healthcare utilization of older adults and describes the numbers of readmissions and deaths for the most frequently occurring aftercare arrangements as a starting point in optimizing the post-discharge healthcare organization. Methods This cross-sectional study included older adults insured with the largest Dutch insurance company. We described the utilization of healthcare within 180 days after discharge from their first hospital admission of 2015 and the most frequently occurring combinations of aftercare in the form of geriatric rehabilitation, community nursing, long-term care, and short stay during the first 90 days after discharge. We calculated the proportion of older adults that was readmitted or had died in the 90-180 days after discharge for the six most frequent combinations. We performed all analyses in the total group of older adults and in a sub-group of older adults who had been hospitalized due to a hip fracture. Results A total of 31.7% of all older adults and 11.4% of the older adults with a hip fracture did not receive aftercare. Almost half of all older adults received care of a community nurse, whereas less than 5% received long-term home care. Up to 18% received care in a nursing home during the 6 months after discharge. Readmissions were lowest for older adults with a short stay and highest in the group geriatric rehabilitation + community nursing. Mortality was lowest in the total group of older aldults and subgroup with hip fracture without aftercare. Conclusions The organization of post-discharge healthcare for older adults may not be organized sufficiently to guarantee appropriate care to restore functional activity. Although receiving aftercare is not a clear predictor of readmissions in our study, the results do seem to indicate that older adults receiving community nursing in the first 90 days less often die compared to older adults with other types of aftercare or no aftercare. Future research is necessary to examine predictors of readmissions and mortality in both older adult patients discharged from hospital.</p

Sustainability of Long-term Care: Puzzling Tasks Ahead for Policy-Makers

Abstract Background: The sustainability of long-term care (LTC) is a prominent policy priority in many Western countries. LTC is one of the most pressing fiscal issues for the growing population of elderly people in the European Union (EU) Member States. Country recommendations regarding LTC are prominent under the EU&apos;s European Semester. Methods: This paper examines challenges related to the financial-and organizational sustainability of LTC systems in the EU. We combined a targeted literature review and a descriptive selected country analysis of: (1) public-and private funding; (2) informal care and externalities; and (3) the possible role of technology in increasing productivity. Countries were selected via purposive sampling to establish a cohort of country cases covering the spectrum of differences in LTC systems: public spending, private funding, informal care use, informal care support, and cash benefits. Results: The aging of the population, the increasing gap between availability of informal care and demand for LTC, substantial market failures of private funding for LTC, and fiscal imbalances in some countries, have led to structural reforms and enduring pressures for LTC policy-makers across the EU. Our exploration of national policies illustrates different solutions that attempt to promote fairness while stimulating efficient delivery of services. Important steps must be taken to address the sustainability of LTC. First, countries should look deeper into the possibilities of complementing public-and private funding, as well as at addressing market failures of private funding. Second, informal care externalities with spill-over into neighboring policy areas, the labor force, and formal LTC workers, should be properly addressed. Thirdly, innovations in LTC services should be stimulated to increase productivity through technology and process innovations, and to reduce costs. Conclusion: The analysis shows why it is difficult for EU Member State governments to meet all their goals for sustainable LTC, given the demographic-and fiscal circumstances, and the complexities of LTC systems. It also shows the usefulness to learn from policy design and implementation of LTC policy in other countries, within and outside the EU. Researchers can contribute by studying conditions, under which the strategies explored might deliver solutions for policy-makers

Myeloid DLL4 Does Not Contribute to the Pathogenesis of Non-Alcoholic Steatohepatitis in Ldlr-/- Mice.

Non-alcoholic steatohepatitis (NASH) is characterized by liver steatosis and inflammation. Currently, the underlying mechanisms leading to hepatic inflammation are not fully understood and consequently, therapeutic options are poor. Non-alcoholic steatohepatitis (NASH) and atherosclerosis share the same etiology whereby macrophages play a key role in disease progression. Macrophage function can be modulated via activation of receptor-ligand binding of Notch signaling. Relevantly, global inhibition of Notch ligand Delta-Like Ligand-4 (DLL4) attenuates atherosclerosis by altering the macrophage-mediated inflammatory response. However, the specific contribution of macrophage DLL4 to hepatic inflammation is currently unknown. We hypothesized that myeloid DLL4 deficiency in low-density lipoprotein receptor knock-out (Ldlr-/-) mice reduces hepatic inflammation. Irradiated Ldlr-/- mice were transplanted (tp) with bone marrow from wild type (Wt) or DLL4f/fLysMCre+/0 (DLL4del) mice and fed either chow or high fat, high cholesterol (HFC) diet for 11 weeks. Additionally, gene expression was assessed in bone marrow-derived macrophages (BMDM) of DLL4f/fLysMCreWT and DLL4f/fLysMCre+/0 mice. In contrast to our hypothesis, inflammation was not decreased in HFC-fed DLL4del-transplanted mice. In line, in vitro, there was no difference in the expression of inflammatory genes between DLL4-deficient and wildtype bone marrow-derived macrophages. These results suggest that myeloid DLL4 deficiency does not contribute to hepatic inflammation in vivo. Since, macrophage-DLL4 expression in our model was not completely suppressed, it can't be totally excluded that complete DLL4 deletion in macrophages might lead to different results. Nevertheless, the contribution of non-myeloid Kupffer cells to notch signaling with regard to the pathogenesis of steatohepatitis is unknown and as such it is possible that, DLL4 on Kupffer cells promote the pathogenesis of steatohepatitis

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

Complex Governance Does Increase Both the Real and Perceived Registration Burden: The Case of the Netherlands Comment on “Perceived Burden Due to Registrations for Quality Monitoring and Improvement in Hospitals: A Mixed Methods Study”

The burden of registrations for professionals should be more firmly on the policy agenda. In a rigorous study, Marieke Zegers and colleagues make a compelling argument why that should be the case. In Dutch hospitals, the average professional spends 52.3 minutes a day on quality registries and monitoring instruments. Many more administrative duties exist. These represent substantial resources and ultimately could become a drag on the intrinsic motivation of the care professions. We agree with Zegers et al that we are in need for more operational efficiency. However, the issue at hand is very complex and also intensely connected to the entire healthcare system and its different levels. More operational efficiency alone will not solve this problem. We are also in need for better governance of data-issues at the macro-system level

Inventory and analysis of literature on the organisation of eight European academic medical centres-A scoping review.

Academic Medical Centres (AMCs) are important organisations for shaping healthcare. The purpose of this scoping review is to understand the scope and type of evidence related to the organisation of European AMCs. We selected the study population intending to obtain a demographic cross-section of European countries: Czech Republic, Germany, Latvia, the Netherlands, Poland, Spain, Sweden and the UK. We focused our search strategy on the relationship between medical schools and AMCs, the organisation of governing bodies, and legal ownership. We searched the bibliographic databases of PubMed and Web of Science (most recent search date 17-06-2022). To enrich the search result, we used Google search engines to conduct targeted searches for relevant websites. Our search strategy yielded 4,672 records for consideration. After screening and reviewing full-text papers, 108 sources were included. Our scoping review provided insight into the scope and type of evidence related to the organisation of European AMCs. Limited literature is available on the organisation of these AMCs. Information from national-level websites complemented the literature and provided a more complete picture of the organisation of European AMCs. We found some meta-level similarities regarding the relationship between universities and AMCs, the role of the dean and the public ownership of the medical school and the AMC. In addition, we found several reasons why a particular organisational and ownership structure was chosen. There is no uniform model for AMC organisations (apart from some meta-level similarities). Based on this study, we cannot explain the diversity in these models. Therefore, further research is needed to explain these variations. For example, by generating a set of hypotheses through in-depth case studies that also focus on the context of AMCs. These hypotheses can then be tested in a larger number of countries

Deformation and martensitic phase transformation in stainless steels

The use of high-energy synchrotron x-rays which has enabled three- dimensional structural characterization from the nano- to the macroscopic scale, and now to the meso-scale, such as individual grains and dislocation structures, is a major scientific advance. This is the first technique with sufficient spatial resolution and penetration power to probe the local structure embedded deep within the material. This, together with good time resolution makes it suitable for investigations of e.g. phase transformations kinetics, stress-strain behaviour, and texture evolution in stainless steels. The micromechanical response of a metastable austenitic stainless steel and a duplex stainless steel during loading has been investigated by a series of high-energy x-ray diffraction experiments at the Advanced Photon Source (APS) in Argonne, IL, USA. Different measurement scales of the steels are tested, ranging from the behaviour of individual grains up to the macroscopic material behaviour. The experimental data is used as input to material models to validate and improve existing models for strain-induced martensite and mechanical properties. The x-ray investigations have revealed that autocatalytic Ü-martensite transformation is triggered by strains induced by the transformation itself in 301 and this was evidenced as bursts of Ü-martensite transformation during tensile loading. To the author's knowledge this behaviour has not been previously reported, and is of significant importance for the mechanical properties of the metastable stainless steels, since it provides strong local hardening and increases the time to neck formation. The å-martensite formation was investigated for 45 individual austenite bulk grains in 301 and the resolved shear stress was determined. Out of the 45 austenite grains probed one was observed to form å-martensite. The grain that formed å-martensite had the highest Schmid factor for the active slip system during fcc to hcp transformation. The behaviour of 301 during tensile loading at different strain rates was also investigated and it was concluded that even moderate strain rates produce adiabatic heating sufficient to suppress the martensite formation. The strain-induced martensitic transformation and the stress-strain behaviour was predicted by an extended Olson-Cohen model, finite element simulations for the temperature evolution and a radial return algorithm for the stress-strain behaviour. The measured and modelled results were in fair agreement. In addition, the phase specific stresses were measured during the experiments and these were in good agreement with the predicted results from the finite element model. Thus, it was concluded that the employed iso- work principle was a good assumption for the stress distribution between the phases. One way of tailoring the metastable austenitic stainless steels' microstructure with different phase fractions and deformation structures is by the reverse transformation from martensite to austenite. This was investigated for the cold rolled 301 steel, and the reverse transformation was observed to occur via two different mechanisms, one diffusion controlled and the other a diffusionless transformation. The onset of the diffusion reversion was about 450°C and the shear reversion became active at higher temperatures. The microstructure of shear reversed austenite consists of highly faulted austenite with an inherited lath like structure. The stress response of 15 individual austenite and ferrite grains deeply embedded in the bulk of a duplex stainless steel was measured during tensile loading. These results showed large intergranular stresses acting between grains due to grain interaction. The large intergranular stresses will have a significant effect on the two-phase behaviour during loading.Godkänd; 2007; 20071126 (ysko

The Effect of Noninvasive Telemonitoring for Chronic Heart Failure on Health Care Utilization: Systematic Review

BackgroundChronic heart failure accounts for approximately 1%-2% of health care expenditures in most developed countries. These costs are primarily driven by hospitalizations and comorbidities. Telemonitoring has been proposed to reduce the number of hospitalizations and decrease the cost of treatment for patients with heart failure. However, the effects of telemonitoring on health care utilization remain unclear. ObjectiveThis systematic review aims to study the effect of telemonitoring programs on health care utilization and costs in patients with chronic heart failure. We assess the effect of telemonitoring on hospitalizations, emergency department visits, length of stay, hospital days, nonemergency department visits, and health care costs. MethodsWe searched PubMed, Embase, and Web of Science for randomized controlled trials and nonrandomized studies on noninvasive telemonitoring and health care utilization. We included studies published between January 2010 and August 2020. For each study, we extracted the reported data on the effect of telemonitoring on health care utilization. We used P<.05 and CIs not including 1.00 to determine whether the effect was statistically significant. ResultsWe included 16 randomized controlled trials and 13 nonrandomized studies. Inclusion criteria, population characteristics, and outcome measures differed among the included studies. Most studies showed no effect of telemonitoring on health care utilization. The number of hospitalizations was significantly reduced in 38% (9/24) of studies, whereas emergency department visits were reduced in 13% (1/8) of studies. An increase in nonemergency department visits (6/9, 67% of studies) was reported. Health care costs showed ambiguous results, with 3 studies reporting an increase in health care costs, 3 studies reporting a reduction, and 4 studies reporting no significant differences. Health care cost reductions were realized through a reduction in hospitalizations, whereas increases were caused by the high costs of the telemonitoring program or increased health care utilization. ConclusionsMost telemonitoring programs do not show clear effects on health care utilization measures, except for an increase in nonemergency outpatient department visits. This may be an unwarranted side effect rather than a prerequisite for effective telemonitoring. The consequences of telemonitoring on nonemergency outpatient visits should receive more attention from regulators, payers, and providers. This review further demonstrates the high clinical and methodological heterogeneity of telemonitoring programs. This should be taken into account in future meta-analyses aimed at identifying the effective components of telemonitoring programs

The Relationship Between the Scope of Essential Health Benefits and Statutory Financing: An International Comparison Across Eight European Countries Implications for policy makers

Abstract Background: Both rising healthcare costs and the global financial crisis have fueled a search for policy tools in order to avoid unsustainable future financing of essential health benefits. The scope of essential health benefits (the range of services covered) and depth of coverage (the proportion of costs of the covered benefits that is covered publicly) are corresponding variables in determining the benefits package. We hypothesized that a more comprehensive health benefit package may increase user costsharing charges. Methods: We conducted a desktop research study to assess the interrelationship between the scope of covered health benefits and the height of statutory spending in a sample of 8 European countries: Belgium, England, France, Germany, the Netherlands, Scotland, Sweden, and Switzerland. We conducted a targeted literature search to identify characteristics of the healthcare systems in our sample of countries. We analyzed similarities and differences based on the dimensions of publicly financed healthcare as published by the European Observatory on Health Care Systems. Results: We found that the scope of services is comparable and comprehensive across our sample, with only marginal differences. Cost-sharing arrangements show the most variation. In general, we found no direct interrelationship in this sample between the ranges of services covered in the health benefits package and the height of public spending on healthcare. With regard to specific services (dental care, physical therapy), we found indications of an association between coverage of services and cost-sharing arrangements. Strong variations in the volume and price of healthcare services between the 8 countries were found for services with large practice variations. Conclusion: Although reducing the scope of the benefit package as well as increasing user charges may contribute to the financial sustainability of healthcare, variations in the volume and price of care seem to have a much larger impact on financial sustainability. Policy-makers should focus on a variety of measures within an integrated approach. There is no silver bullet for addressing the sustainability of healthcare. Implications for policy makers • Reduction of the scope of the benefit package and an increase of user charges has limited impact on the reduction of the volume and cost of care at the macro level. Supply constraints may have a much larger impact on reducing the volume of care and thus the long-term financial sustainability of public healthcare provision. • Policy-makers should focus on a variety of measures within an integrated approach, including considerations for services covered, costsharing arrangements, stimulating evidence-based practice, the monitoring and reduction of unwarranted variation, and control mechanisms for the price of healthcare services. Implications for public Coverage for healthcare services funded by public revenues in our sample of 8 European countries is comparable and comprehensive, with only marginal differences. It is the cost-sharing arrangements for citizens that vary the most, and they imply different thresholds for individual access to specific health services in the selected countries

Cancer treatments touch a wide range of values that count for patients and other stakeholders: What are the implications for decision‐making?

Abstract Background Cancer rates and expenditures are increasing, resulting in debates on the exact value of this care. Perspectives on what exactly constitutes worthwhile values differ. This study aims to explore all values–elements regarding new oncological treatments for patients with cancer and all stakeholders involved and to assess their implications in different decision‐making procedures. Method Thirty‐one individual in‐depth interviews were conducted with different stakeholders to identify values within oncology. A focus group with seven experts was performed to explore its possible implications in decision‐making procedures. Results The overarching themes of values identified were impact on daily life and future, costs for patients and loved ones, quality of life, impact on loved ones, societal impact and quality of treatments. The expert panel revealed that the extended exploration of values that matter to patients is deemed useful in patient‐level decision‐making, information provision, patient empowerment and support during and after treatment. For national reimbursement decisions, implications for the broad range of values seems less clear. Conclusion Clinical values are not the only ones that matter to oncological patients and the stakeholders in the field. We found a much broader range of values. Proper recognition of values that count might add to patient‐level decision‐making, but implications for reimbursement decisions are less clear. The results could be useful to guide clinicians and policymakers when it comes to decision‐making in oncology. Making more explicit which values counts for whom guarantees a more systematic approach to decision‐making on all levels
