[Teleradiological report turnaround times: An internal efficiency and quality control analysis]. / Teleradiologische Prozess- und Untersuchungszeiten: Eine institutsinterne Effizienz- und Qualitätsanalyse.

AIMS: The teleradiological examinations performed at the Charité were analyzed for the purpose of internal quality and efficiency control. Data included the type and number of examinations performed, the time of day and week the examination was performed and the differences in teleradiologist report turnaround times. MATERIAL AND METHODS: A retrospective analysis of the radiology information system (RIS) database of all teleradiological computed tomography examinations performed at the Charité from 2011 through 2013 was carried out. The search retrieved 10,200 teleradiological examinations which were included in the analysis. The records were analyzed for the time of the day and week the examination was performed, the interval between examination and time of reporting, the type of teleradiological examination and the campus in which they were performed. RESULTS: The number of teleradiological examinations performed increased continuously during the observation period. Computed tomography of the head was the most frequently performed type of examination with 86%. Taking all forms of examination into consideration it took an average of 34 min until a report was written. Over the 3-year observation period the times remained virtually unaltered. CONCLUSION: During the 3-year observation period nearly constant report times could be observed in spite of the increased numbers of examinations. This indicates an efficiency enhancement and rational integration of teleradiology into the radiological workflow.

Costs and effects of new professional roles: Evidence from a literature review.

One way in which governments are seeking to improve the efficiency of the health care sector is by redesigning health services to contain labour costs. The aim of this study was to investigate the impact of new professional roles on a wide range of health service outcomes and costs. A systematic literature review was performed by searching in different databases for evaluation papers of new professional roles (published 1985-2013). The PRISMA checklist was used to conduct and report the systematic literature review and the EPHPP-Quality Assessment Tool to assess the quality of the studies. Forty-one studies of specialist nurses (SNs) and advanced nurse practitioners (ANPs) were selected for data extraction and analysis. The 25 SN studies evaluated most often quality of life (10 studies), clinical outcomes (8), and costs (8). Significant advantages were seen most frequently regarding health care utilization (in 3 of 3 studies), patient information (5 of 6), and patient satisfaction (4 of 6). The 16 ANP studies evaluated most often patient satisfaction (8), clinical outcomes (5), and costs (5). Significant advantages were seen most frequently regarding clinical outcomes (5 of 5), patient information (3 of 4), and patient satisfaction (5 of 8). Promoting new professional roles may help improve health care delivery and possibly contain costs. Exploring the optimal skill-mix deserves further attention from health care professionals, researchers and policy makers.

[Economic Evaluation of Integrated Care Systems - Scientific Standard Specifications, Challenges, Best Practice Model]. / Ökonomische Erfolgsmessung von integrierten Versorgungsnetzen - Gütekriterien, Herausforderungen, Best-Practice-Modell.

PURPOSE: Transparency of economic performance of integrated care systems (IV) is a basic requirement for the acceptance and further development of integrated care. Diverse evaluation methods are used but are seldom openly discussed because of the proprietary nature of the different business models. The aim of this article is to develop a generic model for measuring economic performance of IV interventions. METHODS: A catalogue of five quality criteria is used to discuss different evaluation methods -(uncontrolled before-after-studies, control group-based approaches, regression models). On this -basis a best practice model is proposed. RESULTS: A regression model based on the German morbidity-based risk structure equalisation scheme (MorbiRSA) has some benefits in comparison to the other methods mentioned. In particular it requires less resources to be implemented and offers advantages concerning the relia-bility and the transparency of the method (=important for acceptance). Also validity is sound. Although RCTs and - also to a lesser -extent - complex difference-in-difference matching approaches can lead to a higher validity of the results, their feasibility in real life settings is limited due to economic and practical reasons. That is why central criticisms of a MorbiRSA-based model were addressed, adaptions proposed and incorporated in a best practice model: Population-oriented morbidity adjusted margin improvement model (P-DBV(MRSA)). CONCLUSION: The P-DBV(MRSA) approach may be used as a standardised best practice model for the economic evaluation of IV. Parallel to the proposed approach for measuring economic performance a balanced, quality-oriented performance measurement system should be introduced. This should prevent incentivising IV-players to undertake short-term cost cutting at the expense of quality.

[Nursing tasks left undone in German acute care hospitals - results from the international study RN4Cast]. / Implizite Rationierung von Pflegeleistungen in deutschen Akutkrankenhäusern - Ergebnisse der internationalen Pflegestudie RN4Cast.

BACKGROUND: Implicit rationing of nursing care - likewise as in medical care - has never been empirically measured in German hospitals. Thus, little is known about prevalence and patterns of nursing care left undone as well as its association with nurse work environment and staffing. METHODOLOGY: We surveyed 1,511 registered nurses from 49 German acute hospitals participating in the multi-country cross-sectional study RN4CAST. Analyses were made by descriptive statistics as well as multilevel regression analysis to calculate predictors from the nurse work environment and staffing. RESULTS: On average 4.7 out of 13 nursing tasks were rationed. The range was between 82% for "comfort/talk with patients" and 15% for "treatments and procedures". The analysis revealed that hospital work environments and staffing ratios were significantly associated with the level of nursing care left undone. Further significant associations were found between poor leadership, inadequate organisation of nursing work as well as high emotional exhaustion and rationing. DISCUSSION: The phenomenon of nursing care left undone was prevalent in German hospitals. Those tasks which are most likely to have negative consequences for patients (e. g., pain management and medication on time) seem to receive higher priority than tasks whose potential effects are less immediate or direct (e. g., psychosocial care). With regard to the measured correlation with the nurse work environment, it is recommend to invest in a good environment before (or simultaneously) investing in nurse staffing.

[Do German DRGs appropriately explain the resource consumption of hospitals? An empirical patient-level cost-data analysis across ten episodes of care]. / Können deutsche DRGs den Ressourcenverbrauch eines Krankenhauses sachgerecht abbilden? Eine empirische Analyse auf Grundlage von patientenbezogenen Kosten- und Leistungsdaten für 10 Krankheitsbilder.

AIM OF THE STUDY: The revenues of German hospitals are mainly determined by DRG-based payments. Therefore DRGs should appropriately explain the resource consumption of hospitals in order to avoid unintended consequences. So far little is known about the ability of German DRGs to adequately reflect the cost of a hospital stay. METHODS: Regression techniques were applied using anonymised year 2008 cost and performance data of 50,156 cases from 29 hospitals for 10 common episodes of care in order a) to analyse the impact of patient and treatment characteristics on costs and b) to test if DRG variables are better in explaining resource consumption than this set of patient variables. RESULTS: Depending on the episode of care, patient and treatment variables have a different impact on hospital costs. However, they are better in explaining resource consumption than the DRG variables for each episode of care. In addition, independent of the patient characteristics hospitals have an impact on costs which might be due to factors that are not considered by the DRG-system. CONCLUSION: The analysis shows that the German DRG system requires further research. However, to date this is limited by poor data availability. Compared to other DRG systems the German system shows a weak performance. The incorporation of some of the used variables as well as an increasing international knowledge transfer might help to further improve the German DRG system.

[DRG systems in Europe. Incentives, purposes and differences in 12 countries]. / DRG-Systeme in Europa. Anreize, Ziele und Unterschiede in zwölf Ländern.

DRG systems were introduced across Europe based on expected transparency and efficiency gains. However, European DRG systems have not been systematically analysed so far. As a consequence little is known about the relative strengths and weaknesses of different DRG systems. The EuroDRG project closed this research and knowledge gap by systematically analysing and comparing the DRG systems of 12 countries with different health systems (Austria, the UK, Estonia, Finland, France, Germany, Ireland, The Netherlands, Poland, Portugal, Spain and Sweden).This article summarizes the results of this analysis illustrating how DRG systems across Europe differ with regard to policy goals, patient classification, data collection, price setting and actual reimbursement. Moreover, it outlines which main challenges arise within and across the different types of DRG systems. The results show that the European DRG systems are very heterogeneous. Even if the basic DRG approach of grouping similar patients remains the same across countries, the design of the main building blocks differs to a great extent.

[Regional differences in life expectancy in Germany at county levels and their possible determinants]. / Regionale Unterschiede der Lebenserwartung in Deutschland auf Ebene der Kreise und kreisfreien Städte und deren möglichen Determinanten.

The aim of this study is to show health differences at a county level in Germany and to identify possible reasons for these differences. The study calculates life expectancy as being representative for the health status. The analytical part of the study uses a wide database with socioeconomic, environmental, educational and health-care data. In a first step, the set of variables is reduced by a factor analysis and three factors are generated (socioeconomic conditions, environment, health-care). Secondly, a cluster analysis is used to show the regional distribution of the gained factors and thirdly a regression analysis is used to show the influence of the three factors on life expectancy. The results of the regression analysis show that socioeconomic conditions have the greatest influence on health status. Because of this, preventive health-care measures should integrate an improvement of socioeconomic conditions.

[Amenable mortality in Germany: spatial distribution and regional concentrations]. / Vermeidbare Sterbefälle in Deutschland: Räumliche Verteilung und regionale Konzentrationen.

AIM: The aim of this study is to identify small areas in Germany burdened by exceptionally high rates of amenable mortality using the 439 counties as unit of analysis. METHODS: To overcome shortcomings of conventional mortality measures, we construct an indicator for amenable mortality (AM) which captures deaths that should not occur given current medical knowledge and technology. We age-standardize individual-level data on mortality for the years 2000-2004 and plot the distribution of disease-specific AM on country maps. We consider deaths following ischaemic heart disease, cerebrovascular diseases, hypertension, diseases of the liver, traffic accidents, several cancer types and 24 other diseases that are classified as amenable to health care. The data is taken from the causes-of-death statistics (provided by Destatis). RESULTS: AM significantly differs between small areas within and between German federal states (Bundeslaender). Breast cancer and lung cancer in men are the most common AM-causes in Germany. The often discussed mortality-gap between East and West Germany is predominantly driven by differences in amenable deaths following cardiovascular diseases. However, the maps of most carcinogenic deaths show a north-south gradient rather than an east-west difference.

Poland: health system review

The Health Systems in Transition (HiT) country profiles provide an analytical description of each health system and of policy initiatives in progress or under development. They aim to provide relevant comparative information to support policy-makers and analysts in the development of health systems and reforms in the countries of the WHO European Region and beyond. The HiT profiles are building blocks that can be used: to learn in detail about different approaches to the financing, organization and delivery of health services; to describe accurately the process, content and implementation of health reform programmes; to highlight common challenges and areas that require more in-depth analysis; and to provide a tool for the dissemination of information on health systems and the exchange of experiences of reform strategies between policy-makers and analysts in countries of the WHO European Region. This series is an ongoing initiative and material is updated at regular intervals.

[Priority setting in healthcare. What can Germany learn from other countries?]. / Priorisierung in anderen Gesundheitssystemen. Was kann Deutschland lernen?

Internationally, priority setting has been debated since the late 1980s, partly only regarding underlying principles, but partly with real implications for the benefit basket. Whereas all approaches reviewed (Norway, Sweden, Denmark, Oregon, The Netherlands, New Zealand) are convincing, those that relied on public consensus and left the priority-setting principles to the discretion of individual healthcare professionals had no effect as early prioritization efforts in the Scandinavian countries show. Prioritization approaches that have relied on concrete lists of indication-treatment pairs (for example, in the U.S. state of Oregon across all areas of care and in Sweden the form of guidelines within indication groups) have led to changes but not always to the expected results: expenditure was only moderately reduced but the provision of care has become more transparent. Regardless of the differences between the various countries, they have several things in common: a heated public debate, a very long implementation timeline, and the lack of a (much feared) prioritization according to age, gender, or social status. Recently, priority setting has been seen as complementary to health technology assessments, guidelines, and quality assurance, all with their own focuses.

[Do primary care physicians acting as gatekeepers really improve health outcomes and decrease costs? A systematic review of the concept gatekeeping]. / Macht der Hausarzt als Lotse die Gesundheitsversorgung wirklich besser und billiger? Ein systematischer Review zum Konzept Gatekeeping.

AIM: The aim of this systematic review was to analyse the effects of gatekeeping where primary care physicians (PCP) control access to specialist care. METHODS: Literature search in Medline, EMBASE, Cochrane Library, and a hand search were carried out. INCLUSION CRITERIA: (1) intervention: gatekeeping by PCP compared to free access to specialist care; (2) outcomes: health outcomes, health related quality of life, quality of care, utilization of care, costs, satisfaction of patients and providers; (3) design: RCT, quasi-random. CT, CBA, cohort and case control studies, ITS. Data extraction and assessment was done by two independent reviewers according to Cochrane EPOC-Group and USTFCPS. RESULTS: 24 included studies (1989-2007) were as follows: 1 RCT, 2 quasi-randomised CT, 3 prospective, and 12 retrospective cohort studies, 4 CBA, and 2 ITS. 67% of the studies analysed data from the USA, the remaining from CH, UK, DK and NL. Studies had relevant limitations concerning the quality of execution and publication. Overall 13 of 24 studies reported a positive and two a negative effect of gatekeeping compared to open access models; nine showed no differences. The results varied according to outcome parameters. CONCLUSIONS: International evidence on effects of gatekeeping is limited by the low internal validity of studies and applicability to other contexts. It suggests that gatekeeping by PCP decreases utilization of specialist care and health care costs. Based on very few studies health outcomes and patient quality of life in gatekeeping models might be comparable with those in open access models. Evidence is inconsistent or not available concerning the quality of care, patient or provider satisfaction.

Drug prescription patterns in schizophrenia outpatients: analysis of data from a German health insurance fund.

INTRODUCTION: The aim of this study was to investigate routine administrative data from a major German health insurance fund, Techniker Krankenkasse, which covers 5.4 million insured individuals. Using a retrospective cohort design, this study analysed data collected from patients with a hospital diagnosis of schizophrenia in 2003 (index hospitalisation) in order to evaluate prescription patterns of antipsychotic drugs. METHODS: Patients with an ICD-10 diagnosis of schizophrenia, at least one year prior membership with the insurance fund and a follow-up period of one year were identified. Results were standardised by age and stratified by the severity of their illness, defined by the number of hospital bed days during the three years preceding the index hospitalisation. RESULTS: A total of 3,121 patients with schizophrenia (male 56.4%, female 43.6%) received 56 692 single prescriptions of antipsychotics. Of these, 35.4% of the prescriptions were for typical and 64.6% for atypical antipsychotics; 55% were for high-potency, 45% for low-potency typical antipsychotics. The most frequently prescribed drugs were olanzapine (26.6%), clozapine (21.3%) and risperidone (19%). There were no relevant gender differences concerning prescription patterns. During a 12-month follow-up period after the first hospitalisation, 1 372 patients (43.9%) were treated exclusively with an atypical antipsychotic, another 499 patients (16%) had a combination of an atypical plus a low-potency typical antipsychotic. Thus, basal therapy with an atypical was observed in 59.9% of our study population. Only 327 patients (10.5%) were treated exclusively with a typical antipsychotic. A total of 645 patients (20.7%) were treated with a combination of atypical plus typical antipsychotic. Changes of medication within one substance group occurred more often with typical antipsychotics (50%) as compared to atypical antipsychotics (25%). DISCUSSION: At 60%, the proportion of patients in this study treated with atypical antipsychotics was surprisingly high. Of significant interest is the frequent prescription of clozapine (14%). The results are discussed in comparison to comparable studies from other countries.

Performance of reimbursement schemes in valuation of technologies: the example of magnetic resonance imaging.

Different reimbursement schemes for health care providers have been developed worldwide. They have evolved over time and have been influenced by politics, costs, patient needs and technological progress. Different methods in the valuation of technologies and their reflection in outpatient reimbursement schemes are analyzed. Using Magnetic Resonance Imaging (MRI) as an example, five different reimbursement schemes from four countries are compared according to defined performance criteria. Major differences in the structure and valuation of internationally used reimbursement schemes are presented; Prices for Neurocranium MRI scans vary from euro98 to euro462 and large discrepancies can even be found within the same country. There are politically driven reimbursement schemes like the German Gebührenordnung für 'A'rzte, while others such as the Swiss TARMED are primarily based on actual costs.

[Susceptibility to strategy of the drug component of the IPHCC+RxGroups classification system in a risk-adjusted morbidity compensation scheme--a conceptional and data-supported analysis]. / Zur Strategieanfälligkeit der Arzneimittelkomponente des IPHCC+RxGroups-Klassifikationssystems in einem morbiditätsorientierten Risikostrukturausgleich--Eine konzeptionelle und datengestützte Analyse.

BACKGROUND: A report commissioned by the German Ministry of Health recommends to the existing scheme for calculating risk-adjusted transfers to sickness funds supplement with the IPHCC+RxGroups method. The method is based on inpatient diagnoses and prescribed drugs as health status measures deduced from prior use. OBJECTIVE: The present study investigates the sickness fund's expected net return from gaming based on the drug component of the risk adjuster. METHODS: The study explores three possible strategies using the RxGroups method. For the stimulations, insurees are assigned to additional indications or to higher valued RxGroups within the same indication. Then, costs and financial benefits attributable to the altered drug use are estimated and compared with the status quo. The study uses 2000 and 2001 sample data of more than 370,000 insurees of Germany's company-based sickness funds system (BKK). RESULTS: While upgrading increases overall costs, it can be beneficial for the individual sickness funds. Their net return crucially depends on the number of sickness funds gaming the system: the more participating in the game, the smaller is the average net return. Moreover, not participating often is even worse, which in turn points to a prisoner's dilemma. CONCLUSIONS: When extending the risk adjustment scheme in social health insurance, the German legislator should take into account the perverse incentives of risk adjusters such as the described prescription drug model.

Cost-effectiveness analysis of telemedical devices for pre-clinical traffic accident emergency rescue in Germany.

OBJECTIVES: The purpose of this study is to assess the cost-effectiveness (net costs per life year gained) of telemedical devices for pre-clinical traffic accident emergency rescue in Germany. METHODS: Two equipment versions of a telemedical device are compared from a societal perspective with the baseline in Germany, i.e. the non-application of telemedicine in emergency rescues. The analysis is based on retrospective statistical data covering a period of 10 years with discounted costs not adjusted for inflation. Due to the uncertainty of data, certain assumptions and estimates were necessary. The outcome is measured in terms of "life years gained" by reducing therapy-free intervals and improvements in first-aid provided by laypersons. RESULTS: The introduction of the basic equipment version, "Automatic Accident Alert", is associated with net costs per life year gained of euro 247,977 (at baseline assumptions). The full equipment version of the telemedical device would lead to estimated net costs of euro 239,524 per life year gained. Multi-way sensitivity-analysis with best and worst case scenarios suggests that decreasing system costs would disproportionately reduce total costs, and that rapid market penetration would largely increase the system's benefit, while simultaneously reducing costs. CONCLUSION: The net costs per life year gained in the application of the two versions of the telemedical device for pre-clinical emergency rescue of traffic accidents are estimated as quite high. However, the implementation of the device as part of a larger European co-ordinated initiative is more realistic.

[Health systems as an epidemiological topic--or how do we know how effective health systems are?]. / Gesundheitssysteme als epidemiologischer Gegenstand -- oder: Wie wissen wir, wie effektiv Gesundheitssysteme sind?

The article looks at health systems -- especially their effectiveness in improving population health -- from an epidemiological perspective. It demonstrates that research questions and methodologies do not substantially differ from other areas of epidemiological research. Longitudinal designs are superior to the frequently conducted cross-sectional approaches; exposition and outcome parameters need to be carefully defined. A useful approach is "avoidable mortality" which separates medically amenable causes of death from other ones. The article demonstrates that the "exposition health system" has a clearly beneficial effect on population health.

[Health economics. Objectives, methodology, relevance]. / Gesundheitsökonomie. Ziele, Methodik und Relevanz.

The article briefly describes the development of health economics and defines its most important areas of research (e.g. subjective and objective valuation of health; demand for and supply of health services; health insurance; planning, regulation and management; evaluation of health systems; and microeconomic evaluation). Regarding economic evaluation, the article emphasises the choice of comparators, the assessment of costs and effects, the various types of economic analyses, average vs incremental cost-effectiveness, usage of trial data vs modelling as well as sensitivity analyses. It discusses the question of generalisability and introduces a checklist to assess quality and results of published studies.

Defining the "Health Benefit Basket" in nine European countries. Evidence from the European Union Health BASKET Project.

This article identifies and analyses a framework for "health baskets," the taxonomy of benefit catalogues for curative services, and the criteria for the in- or exclusion of benefits in nine EU member states (Denmark, England, France, Germany, Hungary, Italy, The Netherlands, Poland and Spain). Focusing on services of curative care, it is found that the explicitness of benefit catalogues varies largely between the countries. In the absence of explicitly defined benefit catalogues, in- and outpatient remuneration schemes have the character of benefit catalogues. The criteria for the in- or exclusion into benefit catalogues are often not transparent and (cost-)effectiveness is applied only for certain sectors. An EU-wide harmonization of benefit baskets does not seem realistic in the short or medium term as the variation in criteria and the taxonomies of benefit catalogues are large but not insurmountable. There may be scope for a European core basket.

[Pharmaceutical reference pricing in Germany: definition of therapeutic groups, price setting through regression procedure and effects]. / Arzneimittelfestbeträge: Gruppenbildung, Preisberechnung mittels Regressionsverfahren und Wirkungen.

The German reference pricing system defines a reimbursement threshold for groups of pharmaceuticals. Pharmaceuticals are grouped according to certain criteria by the Federal Joint Committee. To make different active ingredients comparable, so called reference values are defined. Subsequently, the federal association of sickness funds sets reference prices using a regression procedure. However, the impact of the reference price system is limited. On the one hand there is a strong incentive for pharmaceutical companies to decrease prices to the reference price. On the other hand there is no incentive for further price reductions. Additionally, only one part of the pharmaceutical market is affected by reference pricing. Therefore the instrument has only managed to lower pharmaceutical expenditure in the short run. For sustainable long-term cost containment the use of other regulatory instruments is necessary. Nevertheless, compared to other instruments of price-regulation, reference pricing seems to be a good alternative to control pharmaceutical prices, since rationing is kept as little as possible.
