[Sense of Coherence Scale according to Antonovsky as a possible predictor for return to work for cardiac surgery intensive care patients]. / "Sense-of-coherence"-Skala nach Antonovsky als möglicher Prädiktor für den Wiedereinstieg in das Berufsleben für herzchirurgische Intensivpatienten.

BACKGROUND: For cardiac surgery patients who were employed prior to surgery, the return to their professional life is of special importance. In addition to medical reasons, such as pre-existing conditions, the success of the operation or postoperative course and patient-intrinsic reasons, which can be assessed with the Sense of Coherence (SOC) scale by Antonovsky, may also play a role in the question of a possible return into working life. METHODS: In this study 278 patients (invasive coronary artery bypass graft surgery and/or surgery on heart valves, age < 60 years, employed) were questioned postoperatively via post with the SOC questionnaire. The SOC questionnaire was used in addition to questions about return to work. The cohort was stratified according to the time of return to work. Subsequently, the point of maximum sensitivity and specificity was determined for the total SOC score and the prediction power was considered. RESULTS: Of the 278 patients, 61 questionnaires (22%) were considered as eligible and included in the analysis. Of these, 47 participants had returned to work after undergoing cardiac surgery and 14 participants had not. We observed significant differences in SOC values between both groups (146.07 ± 29.76 versus 124.29 ± 28.8, p = 0.020). Patients that returned to work within the first 6 months after surgery showed even higher SOC scores (148.56 ± 28.98, p = 0.034). CONCLUSION: Patients with an SOC score < 130 are at greater risk not to return to their professional life after cardiac surgery. The SOC is an easily obtainable score that reliably predicts the probability of return to work after cardiac surgery.

[Quality assurance in German hospitals - federal quality of care monitoring vs. evaluation of routine clinical data. A head-to-head comparison on the example of pressure ulcers]. / Qualitätssicherung in deutschen Krankenhäusern: "Einrichtungsübergreifende Qualitätssicherung" im Vergleich zur "Qualitätsmessung aus Routinedaten". Ein direkter Vergleich am Beispiel "Dekubitus"

Quality assurance is a backbone for the provision of health care. This has lead to the introduction of systems to evaluate and improve patient care. Currently, a 29-category monitoring is mandatory for all German hospitals (EQS, Einrichtungsübergreifende Qualitätssicherung). Since 2007, the incidence rate of pressure ulcers as an indicator for quality of care has been incorporated. A concern associated with the EQS is the requirement for active data entry by doctors and nurses, whereas the US-based patient safety indicator "PSI 3 - pressure ulcer" relies on routine clinical data without the need for additional documentation. In this study, we perform a head-to-head comparison of the 2 methods and analyze the feasibility of implementing the PSI 3 system in German hospitals on the example of pressure ulcer incidence in a German academic hospital. Our analysis shows that the usage of the PSI 3 is feasible. In particular, all clinical data are readily available. Critical advantages of the PSI 3 include the low time consumption and the positive economic impact due to increased work-flow. A prerequisite for the accuracy of the PSI 3 is the careful distinction and documentation of whether a condition (in our case: pressure ulcers) is pre-existing or hospital-acquired. In this regard, the accurate documentation of admission diagnoses is a potential weakness because these are not essential for reimbursement from health insurances and thus tend to be less well documented. In the US and Australia this problem has been addressed by introducing "present on admission" tabs into patient records. In conclusion, our study demonstrates that the usage of a quality assurance system based on routinely acquired clinical data in German hospitals is feasible, and encourages further evaluation.

[§ 116b SGB V (social insurance code, book five) for rheumatology patients. An empirical assessment on the basis of administrative data]. / § 116b SGB V in der rheumatologischen Versorgung. Eine empirische Abschätzung anhand von Routinedaten.

BACKGROUND: The choice between outpatient and inpatient care is currently undergoing major changes within the German health care system with the amendment of § 116b SGB V. This study investigates what proportion of hitherto inpatient rheumatologic care could potentially be given on an outpatient basis. METHODS: The analysis is based on administrative inpatient data from 2004 to 2008 covering approximately 23.6 million private health insurance insurants. The selection of patients with rheumatological diseases was based on diagnosis according to ICD-10 of § 116b SGB V. RESULTS: From 2004 to 2008 the number of all rheumatologic cases increased by 13.9%, while the average length of hospital stay decreased from 9.46 days to 8.08 days and the number of attending hospitals declined by 3.1%. The number of rheumatologic cases with a short inpatient stay (≤2 days) increased by 32.3%. We define the ambulatory potential as the proportion of patients with a short length of stay to the total of inpatient rheumatologic cases; this increased from 25.7% to 29.9%. DISCUSSION: Not all patients with a short inpatient stay can be transferred problem-free to ambulatory care. No channeling of patients to specialized centres has taken place thus far in Germany. Quality of care at the hospitals studied has not been considered. Further data are needed to link administrative data with quality care data.

[Methods of health economic evaluation for health services research]. / Methoden der gesundheitsökonomischen Evaluation in der Versorgungsforschung.

On August 30, 2010, the German Network for Health Services Research [Deutsches Netzwerk Versorgungsforschung e. V. (DNVF e. V.)] approved the Memorandum III "Methods for Health Services Research", supported by the member societies mentioned as authors and published in this Journal [Gesundheitswesen 2010; 72: 739-748]. The present paper focuses on methodological issues of economic evaluation of health care technologies. It complements the Memorandum III "Methods for Health Services Research", part 2. First, general methodological principles of the economic evaluations of health care technologies are outlined. In order to adequately reflect costs and outcomes of health care interventions in the routine health care, data from different sources are required (e. g., comparative efficacy or effectiveness studies, registers, administrative data, etc.). Therefore, various data sources, which might be used for economic evaluations, are presented, and their strengths and limitations are stated. Finally, the need for methodological advancement with regard to data collection and analysis and issues pertaining to communication and dissemination of results of health economic evaluations are discussed.

[Analysis of mortality and convergence tendencies in inpatient care of stroke and myocardial infarction]. / Analyse von Mortalitäten und Konzentrationstendenzen in der stationären Versorgung von Schlaganfall und Myokardinfarkt.

BACKGROUND: An increase in the convergence of medical services toward specialized hospitals with high case numbers as well as the effects on quality of care are often assumed to be the result of diagnosis-related groups (DRGs; case-based lump-sum reimbursement). Estimates of the extent to which these effects occur in emergency diagnoses are not available. METHODS: Claims data relating to approximately 23.6 million insured within the period 2004-2007 (inclusive) were analyzed. All cases with the main diagnosis of stroke (ICD-10: I63 and I64) and myocardial infarction (ICD-10: I21) were included in the study. RESULTS: Increasing case numbers could be observed for all entities within the period studied (myocardial infarction: +12.71%; stroke: +1.73%). The absolute increase in case numbers seems to affect those hospitals with case numbers >100 per year, whereas case numbers of hospital groups including hospitals with low case numbers per year remain unchanged or grow slower. No absolute trend in mortality could be seen. However, a disproportionate rate of mortality in hospitals with low case numbers per year for both diagnoses was observed. CONCLUSION: The convergence of emergency treatment in a few specialized centers has not yet been accelerated by the implementation of DRGs. Essentially, relative changes can be seen due to case number increases in large centers rather than because of service cutbacks and shifts from smaller hospitals. The reason for this could be the need to maintain emergency care in rural regions, while specialized centers are increasingly built in urban areas.

The nocebo effect: a reason for patients' non-adherence to generic substitution?

Substituting generic formulations of the same chemical agent is a common practice in German health care on the basis of so called rebate contracts. The substitution of a medication may affect the patients' adherence or result in adverse events. While adverse events which may be caused by the pharmacological activity of the agent itself can be explained, some non-specific side effects cannot be substantiated referring to pharmacological factors. These adverse reactions are summarized under the term nocebo effect. Since patients experiencing a nocebo effect can subsequently become non-adherent or even discontinue an appropiate therapy, the aim of this article is to study patients' adherence to generic substitution and the extent of the nocebo effect. In MEDLINE and EMBASE, a search was carried out for articles which were published between March 25th, 1989 and March 25th, 2009 by using the following search terms: generic substitution, adherence, non-adherence, non-persistence, rebate contracts, patients' attitude, nocebo, negative placebo effects, placebo adverse reactions, placebo induced side effects and negative placebo responses. In addition a manual search was performed in the reference lists of the articles retrieved. 14 studies met the inclusion and exclusion criteria and were included in this article. The generic substitution was generally accepted by over two thirds of the study populations. But up to 34% of patients being treated for psychological diseases confronted with a change of their medication had additional adverse events. On the basis of the studies analysed, the conclusion can be drawn that the nocebo effect can play a crucial role in the treatment of psychological diseases. Therefore, physicians and pharmacists should be responsible to prevent the nocebo effect through adequately educating the patients.

[Analysis of selection inventives for health insurances after introduction of the morbidity-oriented risk compensation scheme: an empirical analysis]. / Analyse von Selektionsanreizen für Krankenkassen nach Einführung des morbiditätsorientierten Risikostrukturausgleichs: Eine empirische Analyse.

BACKGROUND: The risk compensation scheme (RCS) in the Statutory Health Insurance (SHI) was implemented in 1994 to discourage risk selection between sickness funds. However, several expertise papers have concluded since then that the sociodemographic risk adjusters in place could not adequately curb risk selection. To minimise incentives for risk selection in the Statutory Health Insurance (SHI) further, the RCS was refined in 2009 by adding 80 diseases as additional risk adjusters. In spite of the better compensation of differences in morbidity, however, incentives for risk selection may still persist. In this study, we investigated the association of indicators such as region (number of inhabitants in the city), income, level of education and family status (children in the household) with health care costs to determine if risk selection is still attractive for sickness funds under the refined RCS. METHOD: The analysis is based on a 2002 cross-section survey comprising 75,122 individuals. Health expenditures were estimated using self-documented utilisation data and were standardised for age, sex and diagnoses covered by the risk adjustment scheme. We included costs for inpatient care, outpatient care, pharmaceuticals, rehabilitation, and medical devices. To assess the effects of the above-mentioned individual characteristics on health-care expenditure, regression analyses and analyses of variances were performed. RESULTS: Full documentation was available for 52,484 individuals (69.86%). From these the variables "family status (children in the household)", "higher educational level", and "higher income" were associated with lower costs for individuals without chronic conditions. For individuals with chronic conditions, results were mixed. "Family status", "education" and "income" showed no clear association with lower or higher costs and were not statistically significant. The variable "region" was neither significantly associated with chronically ill nor for healthy individuals. DISCUSSION: With respect to age, sex, and morbidity, individuals with high income and education and without chronic diseases apparently cause lower costs. Thus, health status, income and education remain as possible selection criteria for sickness funds in Germany. However, the refined RCS compensates for the largest proportion of cost differences between insured with and without chronic disease. Possible causes of the small but remaining differences and whether improving preventive programmes or providing awareness campaigns may be appropriate strategies to tackle this issue should be investigated in future research.

[Convergence tendencies in inpatient oncological care after implementation of diagnosis-related groups in Germany]. / Konzentrationstendenzen in der stationären onkologischen Versorgung nach Einführung von Diagnosis-Related Groups in Deutschland.

BACKGROUND: An increase of the convergence of medical services towards specialised hospitals with high case numbers is often assumed as a result of the implementation of diagnosis-related groups (DRG; case-based lump sum reimbursement). So far, estimates of the extent to which this effect occurs after the recent implementation of DRGs are not available in Germany. METHOD: Claims data of about 23,600,000 insured within the inclusive period 2004-2007 were analysed. All cases with the main diagnosis of lung cancer, prostate cancer, and colorectal cancer were included in the study. Broken down by entities and years, graphical and statistical concentration measures as well as the percentages of different hospital size classes were calculated. RESULTS: Increasing case numbers could be observed for all entities within the period (lung cancer:+25.7%; prostate cancer:+12.5%; colorectal cancer:+8.1%). The concentration measures showed hardly any changes in the course of time. The absolute increase of case numbers seems to affect those hospitals with case numbers higher than 50 per year above average [lung cancer cases in a hospital group including hospitals with more than 50 cases 2004 (percentage): 78.1% and 2007: 81.6%; prostate cancer: 67.4% and 71.7%; colorectal: 72.5% and 75.9%], whereas case numbers of hospital groups including hospitals with case numbers less than 50 per year remain unchanged or grow more slowly. DISCUSSION: The convergence of oncological services towards a few specialised centres has not yet been accelerated by the implementation of DRG's. Fundamentally, relative changes can be noticed due to case number increases in large centres, not because of service cutbacks and shifts from smaller hospitals. Reasons for this could either be the inflexibility of capacity planning or control options of the statutory health insurance. CONCLUSION: Further research of convergence tendencies and its drivers is required to be able to draw any benefit from efficiency and quality potentials.

[Performance and costs of outpatient clinics of university hospitals for medical care, teaching, research activities]. / Leistungen und Kosten der Hochschulambulanzen in Forschung, Lehre und Versorgung -- Ergebnisse der Hochschulambulanzenstudie.

BACKGROUND: Outpatient clinics of university hospitals (Hochschulambulanzen) play a significant role in the German health care system. Universities have in contrast to other hospitals the right to implement an outpatient clinic, but the health care services they can render are restricted to clinical research and teaching activities. The university outpatient clinic study evaluates the intensity of medical care, teaching, research activities, and the related costs. METHOD AND DATABASE: 6 university hospitals with 51 outpatient departments in Germany were included. The prospective documentation of consultations was restricted to 800 visits per department. A total of 26,312 consultations with approximately 40,000 diagnoses and 150,000 services were documented. Furthermore, data concerning costs, teaching activities and research facilities were documented. RESULTS: Clinical treatment without any correlation to research or teaching activities amounted to about 81 % of the working time in the outpatient department (research 11 %; teaching 8 %). The primary task of the university outpatient clinics takes up less than 20 % of the working time. The physicians documented that the disease of every fourth visit was in accordance with their main field of research. 6.9 % of the visits were asked to take part in clinical trials, of these 1.25 % were included for the first time, 3.7 % were already included. 6.5 % of the visits were addressed to participate in specific teaching activities. The average total costs per case added up to 149 Euro. No outpatient clinic could cover the total per case costs with the lump sum payments. On the average 31 % of these costs were covered by lump sum payments (without cases concerning research and teaching). CONCLUSION: Treatment in outpatient departments of university clinics is far beyond research and teaching activities required by law. However, the ability of outpatient departments of universities to provide excellent outpatient services should have a more dominant role in the health care system. Therefore access to care should be deregulated for the patients and reimbursement schemes should be adjusted to adjust for the present losses.

[Health policy guidelines for ambulatory and brief inpatient surgery. Backgrounds, facts and possible future solutions]. / Gesundheitspolitischer Rahmen für die ambulante und kurzzeitstationäre Chirurgie. Hintergründe, Fakten und zukünftige Lösungsansätze.

Ambulatory and short-stay surgery in Germany are regulated by two different political committees with different members. Currently, hospitals are permitted to practice ambulatory surgery on the basis of a mere notification sent to the health insurance companies. The details for access, reimbursement, and quality assurance are negotiated between the hospitals' association, the health insurance companies, and the association of the physicians. Compared to other fields of ambulatory care, the legislation for ambulatory surgery is rather loose concerning hospitals' access to this field of health care provision. Short-stay surgery is designated under inpatient care. With the introduction of so-called diagnosis-related groups (DRG) in 2003, a steep decline in length of stay is expected. Further efforts of the government and health insurance companies to extend ambulatory surgery to further indications are expected, too. However, the hurdle of transferring services from the inpatient sector to the ambulatory sector is a major challenge in Germany. We recommend lowering the legislative hurdle hindering hospitals and physicians from entering the area of ambulatory surgery for specific diagnoses. Same-day treatment should also be encouraged.

[Relevance of medical rehabilitation in disease management programmes]. / Bedeutung der medizinischen Rehabilitation in Disease-Management-Programmen.

Disease management programmes will increasingly be introduced in Germany due to the new risk adjustment scheme. The first disease management programmes started in 2003 for breast cancer and diabetes mellitus type II. German rehabilitation will have to face several challenges. Disease management programmes are strongly based on the notion of Evidence so that proof of the efficacy of a care giving task should be present. Verification of the evidence of the specifically German rehabilitation treatments must therefore be given. However, integration of rehabilitation in disease management programmes could lead to changes in the alignment of German rehabilitation. The essence of German rehabilitation, notably its holistic approach, could get lost with integration in disease management programmes.

[Prospective payment in medical rehabilitation]. / Pauschalierte Vergütung in der medizinischen Rehabilitation.

After introducing DRGs (Diagnosis-Related Groups) in the prospective payment system for German hospitals, the use of per-case reimbursement for medical rehabilitation as well is being discussed. In particular two systems have already been tested internationally. FIM-FRG were especially developed for a prospective payment system for inpatient rehabilitation facilities. RUG-III are used for reimbursing long-term care in nursing homes and are based on a per-day payment. It is recommended to test the FIM-FRG or one of the refined systems in Germany in a pilot project.

[Quality control of outpatient imaging examinations in North Rhine-Westphalia, Part II]. / Qualitätskontrolle der ambulanten bildgebenden Diagnostik in Nordrhein-Westfalen, Teil II.

PURPOSE: In the state of North Rhine-Westphalia (NRW), Germany, a survey was conducted on radiologic examinations ordered by general practitioners (GPs). Part II of this study aims to determine the quality of the process and outcome. The reference standard is the assessment of both radiologists and physicians without board certification in radiology working at a university hospital and in outpatient facilities. MATERIALS AND METHODS: AllGPs in NRW were asked to cooperate. Participating GPs filled out a questionnaire for each patient. The patients recorded the symptoms prompting the imaging examinations. The radiologists or other physicians performing the examinations were asked to provide the images and written reports and to complete a questionnaire. A file was created for each of the 394 patients with image documentation of at least one examination. Each file, which included medical history, physical findings, imaging documentation and written report, was sequentially forwarded to a board-certified radiologist and to a physician without board certification in radiology working in a university hospital and in an outpatient facility. All physicians were requested to complete a structured questionnaire for each file. RESULTS: The referral diagnoses were rated as medically plausible in 81%, the indications for imaging found correct in 76%, the examination techniques considered appropriate in 69%, the clinical question answered in 63%, the interpretation judged medically correct in 50% and all incidental findings documented in 49%. In retrospect, 32 % of the examinations were judged superfluous. The sequence of multiple examinations performed on a particular patient was rated as appropriate in 51%. The interpretation revealed specialty-related differences. The plausibility of the referral diagnoses had a significant impact on the appropriateness of subsequent diagnostic investigations. Marked deficits showed sonography, performance by non-radiologists, self-referrals by GPs, gastroenterologic radiology and the ICD-10 coding (suspicion of cardiovascular disease). CONCLUSION: In the "best-case" scenario, the process quality proved to have moderate deficiencies and the outcome quality severe deficiencies. In consequence, GPs and radiologists should be more communicative by sharing information and exchanging opinions. GP self-referrals should be restricted. Sonography and examinations performed by physicians without board certification in radiology should undergo stricter quality controls. A more intensive interdisciplinary collaboration is needed to determine the optimum implementation of diagnostic imaging of gastroenterologic and cardiovascular diseases.

[Quality control of outpatient imaging examinations in North Rhine-Westphalia, part I]. / Qualitätskontrolle der ambulanten bildgebenden Diagnostik in Nordrhein-Westfalen, Teil I.

PURPOSE: In the state of North-Rhine Westphalia (NRW), Germany, a survey was conducted on radiologic examinations ordered by general practitioners (GPs). Part I of this study aims to collect characteristic epidemiological data and to assess structural quality. MATERIALS AND METHODS: All GPs in NRW were asked to cooperate. Participating GPs filled out a questionnaire for each patient. The patients recorded the symptoms prompting the imaging examinations. The radiologists or other physicians performing the examinations were asked to provide the images and written reports and to complete a questionnaire. Two university radiologists documented the pertinent test data from the submitted images and written records. Independently of each other, five university radiologists anonymously reviewed the image quality of each examination using structured questionnaires. RESULTS: A total of 920 patients gave their informed consent and participated. Questionnaires from 787 patients, 852 GPs and 611 radiologists or other interpreting physicians as well as the complete survey data from 530 examinations were available. Of 1503 examinations, conventional radiography made up 52 %, sonography 17 %, computed tomography (CT) 13 % and magnetic resonance imaging (MRI) 5 %. Most indications involved the musculoskeletal (37 %) and respiratory systems (24 %). Physicians without board certification in radiology interpreted 1 % of the CT examinations, 26 % of the radiographic examinations and 71 % of the sonographic examinations. Of the 174 self-referrals, 1 % involved CT, 33 % conventional radiography and 66 % sonography. Written reports were available for 95 % of all 469 examinations performed by radiologists and 74 % of all 127 examinations conducted by non-radiologists. Only 44 % of the 23 sonographic studies were self-referrals by the patient's GP. On average, the radiographic techniques were acceptable in terms of diagnostic information and radiation hygiene. Conventional radiographs were better exposed when obtained by radiologists than by non-radiologists (p = 0.038). The delineation of anatomical structures was rated as good to acceptable for MRI, CT and conventional radiography, while the image quality was rated as diagnostically insufficient for sonography (p < 0.0001). The image quality of radiographic and sonographic examinations performed by radiologists was superior in comparison to examinations performed by physicians without board certification in radiology (p < 0.0001). CONCLUSION: Examination technique and imaging quality of MRI, CT and conventional radiography performed on outpatients were in an acceptable diagnostic range, whereas the quality of sonography was inadequate.

[Result-oriented remuneration for hospital inpatient care]. / Ergebnisorientierte Vergütung stationärer Krankenhausleistungen.

Fee-for-benefit means the adjustment of the reimbursement at the quality of care. Both a bonus and a penalty are possible. It is suggested to measure innovative therapies with outcome parameters and give a bonus as an incentive for quality improvements. Standard therapies should be measured with process parameters and be sanctioned with a penalty when the standards are missed. To determine the extend of the bonus and the penalty, the variable costs of a hospital could be used as a reference. Therefore a penalty should not exceed approximately 25 % of the reimbursement. The costs for the introduction and administration of the fee-for-benefit reimbursement must be seen in the context of the necessary improvement of quality insurance in per-case reimbursement with DRG (Diagnosis-Related Groups) in Germany. Related to the incidence of preventable adverse events and the additional costs of poor-quality outcome evaluated from studies fee-for-benefit will be cost-effective by avoiding every sixth adverse event. German legislation allows fee-for-benefit only in small model projects or local integrated networks. It is recommended to allow an optional opening of negotiations between hospitals and sickness funds for fee-for-benefit elements. A pilot study should evaluate the incidence and cost of preventable adverse events in Germany.

[Extent and causes of coding problems for total compensation on the basis of Diagnosis-Related Groups]. / Ausmass und Ursachen von Kodierproblemen bei pauschalierender Vergütung auf der Basis von Diagnosis-Related Groups.

UNLABELLED: BACKGROUND AND QUESTION: In contrast to the per-day-reimbursement specific data like diagnoses, procedures and demographic data of the patient is needed for a per case reimbursement with Diagnosis Related Groups (DRG). Coding errors can have great impact on the height of the reimbursement. A review of the extent and the causes of coding problems does not exist at present. METHODOLOGY: A systematic search in Medline using the search words >>coding<< and >>error<< and >>hospital<< was performed. Only articles with quantitative evaluation, written in English or German, were included. Literature cited in the articles was included as well. RESULTS: A total of 33 studies (53 113 cases) were identified. An average of 23 % of cases was showing coding problems. Eighteen percent of the cases were assigned to a wrong DRG. Regarding the date of publication no effect in the extent of the coding accuracy could be detected. CONCLUSION: An appreciable rate of cases with coding problems should be anticipated when introducing DRG. Training to improve coding accuracy is recommended. Whether coding should be a task of the ward or the management of the hospital could not be decided here, but it should be noted that this assignment of the coding task has major impact on the allocation of competence in the long run.

[Applicability of diagnostic related groups (DRG) in an international comparison]. / Nutzung von Diagnosis-Related Groups (DRG) im internationalen Vergleich.

Diagnosis-related groups (DRGs) are an instrument for classification of inpatient cases. DRGs are finding ever broader implementation internationally. Targets for using DRGs are hospital financing and budgeting, cost accounting and quality assurance. The present survey covering 18 countries shows that so far DRGs are most frequently used for budgeting purposes. In addition to DRG-based reimbursement, further quality assurance is necessary, but this is only being implemented with hesitation. The coverage planned for all inpatient cases through DRG-based reimbursement in Germany from 2003 on is a pioneering challenge internationally.
