Trends in Acute Inpatient Stroke Care in Germany

Administrative hospital data can be used to detect trends in the care of patients hospitalized with acute stroke. The nationwide German DRG statistics for the years 2005 to 2010 were used to identify hospitalizations for acute stroke. All hospitalizations of patients with a principal diagnosis of acute stroke who were over 19 years old on admission were included in the analysis; admissions transferred from other acute care hospitals were excluded. The data were analyzed to determine annual hospitalization rates, characteristics of the patients and hospitals, patterns of care, and in-hospital mortality. The number of hospitalizations for acute stroke in Germany per year ranged from 235 000 in 2005 to 243 000 in 2010. After standardization for the age and sex structure of the population 2005, the annual hospitalization rate was found to have declined over the period of the study from 357 to 336 hospitalizations per 100 000 persons. The decline occurred mainly in older patients (in men from age 60 and in women from age 70 onward). The percentage of patients cared for in a stroke unit ("complex treatment" in the coding system of the German Classification of Operations and Procedures [Operationen- und Prozedurenschlüssel, OPS]) rose from 15% to 52%. The percentage of patients with cerebral infarction who received systemic thrombolytic treatment rose from 2.4% to 8.9%. In-hospital mortality declined from 11.9% in 2005 to 9.5% in 2010, with a standardized 2005-versus-2010 mortality ratio of 0.79. The declining hospitalization rate of elderly patients might reflect the impact of better primary and/or secondary prevention. The findings also reveal a trend toward more specific care for acute stroke, which may be the cause of the observed decline in in-hospital mortality.

Ertrag und Verlust bei vertebralen Augmentationen im G-DRG-System 2012 – Ein Vergleich des Versorgungsaufwands bei Vertebroplastie und Kyphoplastie

If clearly indicated and implemented, augmentations of vertebral bodies with cement are standardized, safe and low-risk procedures. However, the multiplicity of providers and systems are today more varied than ever. At present, the systems differ starkly from one another not only in specifications, possible applications and extensions of indications, but they are also extremely variable in price. Publications have shown that in times of medical-economic change, vertebral augmentations make sense not only medically, but also in terms of economics and the national economy. Our analysis targets the question of how insurance costs with vertebroplasty and kyphoplasty affect profit margins per G-DRG (German Diagnosis Related Groups) in consideration of the different system approaches of the providers. After reviewing the literature, extremely varied, minimally invasive augmentation methods and techniques for treating vertebral body fractures were identified and classified. These were grouped based also [sic: on] OPS and possibly further subdivisions. Material costs were gathered based on average price quotations of different providers and techniques and aligned with those from the literature. The inpatient costs per day were estimated as a lump sum according to published information, since our analysis was interested in less detailed process costs as these are difficult to transfer to other clinics due to parameters being unique to each facility. The G-DRGs concerned were likewise determined according to the case-based lump sum catalogue from 2012. Based on this, the material costs as well as the daily costs per day of inpatient stay according to the average length of stay per G-DRG were subtracted. Vertebral augmentation methods are classified into vertebroplasty and kyphoplasty according to OPS. In addition, according to current literature, a further subdivision of kyphoplasty into substance-conserving or direct cement injection techniques and substance-destroying or indirect cement injection techniques took place. The procedures involve material costs between 10-40 % of G-DRG revenue. The profit margin of vertebral augmentation ranges from approx. 4100 € to approx. 11 400 €. The calculative costs of the inpatient care per day amount to 488.86 €. Based on the average lengths of stay per G-DRG (7.8-12.6 days) for 2012 determined by the InEK (Institut für das Entgeltsystem im Krankenhaus [Institute for the Hospital Remuneration System]), the financial costs of inpatient care were calculated between 3813.11 € and 6159.65 €. A shortfall of -197.53 € for the treatment of a vertebral body resulted for the vertebroplasty. This shortfall increases with the treatment of three vertebral bodies and a PCCL = 4 to -466.30 €. The indirect cement injection techniques accounted for a positive profit margin of 196.03 € for the treatment of a vertebra. Due to high material costs, however, this dips into the negative in the amount of -1227.70 € for two vertebrae and increases to -2522.50 € for the treatment of three vertebral bodies. In contrast, the multilevel care in substance-preserving kyphoplasty techniques show a positive profit margin of 72.30 € for the treatment of two vertebrae and 577.50 € for the treatment of three vertebrae. Against the background of the increasing economization of the health care system, it should be emphasized once more that the decision for a therapy or a system based on medical reasons should only be made by the treating physician. The vertebroplasty could not be performed at a profit in our analysis, despite comparatively low material costs. A shortfall between -197.53 € and -466.30 € was determined. The comparatively higher material costs of the kyphoplasty make comparisons important. The results of our investigation also show that supposedly inexpensive purchases of materials are not automatically a favorable alternative. In addition, the kyphoplasty techniques currently available on the market are not necessarily comparable. According to our investigation, profits of between 196.03 € and 577.50 € are to be realized in the selection of vertebral augmentation systems based on purely economic considerations. The results of our analysis show that the pure comparison of figures of the average material costs of a G-DRG and the material price distort the picture. A calculation of the profit margin on the basis of costs of care per vertebral body is more definitive.

Assessing DRG cost accounting with respect to resource allocation and tariff calculation: the case of Germany.

The purpose of this paper is to analyze the German diagnosis related groups (G-DRG) cost accounting scheme by assessing its resource allocation at hospital level and its tariff calculation at national level. First, the paper reviews and assesses the three steps in the G-DRG resource allocation scheme at hospital level: (1) the groundwork; (2) cost-center accounting; and (3) patient-level costing. Second, the paper reviews and assesses the three steps in G-DRG national tariff calculation: (1) plausibility checks; (2) inlier calculation; and (3) the “one hospital” approach. The assessment is based on the two main goals of G-DRG introduction: improving transparency and efficiency. A further empirical assessment attests high costing quality. The G-DRG cost accounting scheme shows high system quality in resource allocation at hospital level, with limitations concerning a managerially relevant full cost approach and limitations in terms of advanced activity-based costing at patient-level. However, the scheme has serious flaws in national tariff calculation: inlier calculation is normative, and the “one hospital” model causes cost bias, adjustment and representativeness issues. The G-DRG system was designed for reimbursement calculation, but developed to a standard with strategic management implications, generalized by the idea of adapting a hospital’s cost structures to DRG revenues. This combination causes problems in actual hospital financing, although resource allocation is advanced at hospital level.

A multi-perspective cost-effectiveness analysis comparing rivaroxaban with enoxaparin sodium for thromboprophylaxis after total hip and knee replacement in the German healthcare setting.

BackgroundPatients undergoing major orthopaedic surgery (MOS), such as total hip (THR) or total knee replacement (TKR), are at high risk of developing venous thromboembolism (VTE). For thromboembolism prophylaxis, the oral anticoagulant rivaroxaban has recently been included in the German diagnosis related group (DRG) system. However, the cost-effectiveness of rivaroxaban is still unclear from both the German statutory health insurance (SHI) and the German hospital perspective.ObjectivesTo assess the cost-effectiveness of rivaroxaban from the German statutory health insurance (SHI) perspective and to analyse financial incentives from the German hospital perspective.MethodsBased on data from the RECORD trials and German cost data, a decision tree was built. The model was run for two settings (THR and TKR) and two perspectives (SHI and hospital) per setting.ResultsProphylaxis with rivaroxaban reduces VTE events (0.02 events per person treated after TKR; 0.007 after THR) compared with enoxaparin. From the SHI perspective, prophylaxis with rivaroxaban after TKR is cost saving (€27.3 saving per patient treated). However, the cost-effectiveness after THR (€17.8 cost per person) remains unclear because of stochastic uncertainty. From the hospital perspective, for given DRGs, the hospital profit will decrease through the use of rivaroxaban by €20.6 (TKR) and €31.8 (THR) per case respectively.ConclusionsBased on our findings, including rivaroxaban for reimbursement in the German DRG system seems reasonable. Yet, adequate incentives for German hospitals to use rivaroxaban are still lacking.

Has the DRG system impacted on inpatient allergy care in university dermatology departments in Germany?

Diagnostic provocation tests (ICD Z01.5) have a low cost weight in the German DRG system. We aimed at investigating a possible economic impact on the number of provocation tests in German university medical centers (UMC) for dermatology. We review quality records of 35 German UMC for 2008 and 2010 (ICD Z01.5, total number of patients as well as priority ranking). 33/35 hospitals gave full data for both years including the ten most frequent diagnoses. Between 2008 and 2010, total number of patients treated increased in 23/33 (70 %) UMC, those with ICD Z01.5 only in 11/24 (46 %) UMC with full data. In 2008, the ICD Z01.5 was in the top ten list of main diagnoses in 29/33 (88 %) hospitals, in 2010 in 25/33 (76 %); also, priority ranking tended to decrease. In contrast, total number of ICD Z01.5 in Germany tended to increase slightly. We noticed a tendency for decreasing numbers of provocation tests being performed in dermatological UMC in Germany. As there is no evidence for a decreasing number of patients suffering from allergies, one may speculate about a shift to non-university departments due to an economic impact.

Ökonomische Auswirkungen infizierter Hüfttotalendoprothesen im DRG-System

The treatment of an infected total hip arthroplasty is becoming an increasing economic problem. The additional costs of treatment are insufficiently represented in the diagnosis-related groups (DRG) categories. The aim of this study was to clarify whether the costs can be covered under the German DRG system and to identify the extent of the surplus or negative balance. A retrospective analysis of the treatment costs of total hip arthroplasty was carried out. Data from all patients treated at the orthopedic clinic of the University Hospital in Rostock were collected from patient records and from the hospital information system and calculation of the personnel and material costs using data from the central pharmacy and control centre of the University of Rostock. In this study a total of 49patients were included. The average treatment costs were 29,331.36EUR per patient for an infected and 6,263.59EUR for a primarily non-infected total hip arthroplasty. A comparison between the calculated and compensated costs resulted in an average deficit of 12,685.60EUR per patient and an average surplus of 781.41EUR per patient in the control group. An economically viable treatment of infected total hip arthroplasty was not possible mostly due to the increased personnel and material costs but also to the lack of inclusion of the procedures in the DRG system. Further multicenter cost analysis studies and extensive quality assurance measures are necessary with respect to a comprehensive medical standard for a medically meaningful and economically reasonable treatment of periprosthetic infections.

Die Herausforderung der sachgerechten Vergütung von Schwerverletzten im deutschen DRG-System

Critically injured patients are a very heterogeneous group, medically and economically. Their treatment is a major challenge for both the medical care and the appropriate financial reimbursement. Systematic underfunding can have a significant impact on the quality of patient care. In 2009 the German Trauma Society and the DRG-Research Group of the University Hospital Muenster initialised a DRG evaluation project to analyse the validity of case allocation of critically injured patients within the German DRG system versions 2008 and 2011 with additional consideration of clinical data from the trauma registry of the German Trauma Society. Severe deficits within the G-DRG structure were identified and specific solutions were designed and realised. A retrospective analysis was undertaken of standardised G-DRG data (§ 21 KHEntgG) including case-related cost data from 3 362 critically injured patients in the periods 2007 and 2008 from 10 university hospitals and 7 large municipal hospitals. For 1 241 cases of the sample, complementary detailed information was available from the trauma registry of the German Trauma Society to monitor the case allocation of critically injured patients within the G-DRG system. Analyses of coding and grouping, performance of case allocation, and the homogeneity of costs in the G-DRG versions 2008 and 2011 were done. The following situations were found: (i) systematic underfunding of trauma patients in the G-DRG-Version 2008, especially trauma patients with acute paraplegia; (ii) participation in the official G-DRG development for 2011 with 13 proposals which were largely realised; (ii) the majority of cases with cost-covering in the G-DRG version 2011; (iv) significant improvements in the quality of statistical criteria; (v) overfunded trauma patients with high intensive care costs; (vi) underfunding for clinically relevant critically injured patients not identified in the G-DRG system. The quality of the G-DRG system is measured by the ability to obtain adequate case allocations for highly complex and heterogeneous cases. Specific modifications of the G-DRG structures could increase the appropriateness of case allocation of critically injured patients. Additional consideration of the ISS clinical data must be further evaluated. Data-based analysis is an essential prerequisite for a constructive development of the G-DRG system and a necessary tool for the active participation of medical societies in this process.

Krankenhausfinanzierung 2012 – Relevantes für die Internistische Rheumatologie

The following article presents the major general and specific changes for the financing of rheumatology in Germany for 2012. Besides relevant changes in the German diagnosis-related groups (G-DRG) classification system and for the coding, the new legislation and the resulting incentives are covered. The consequences for hospitals specialized in rheumatology are discussed.

Fallpauschalenentwicklung in der rekonstruktiven Mammachirurgie

Diagnosis-Related Groups (DRG) were introduced in Germany in 2004 as a medico-economic classification system. In this analysis, we looked at reconstructive surgery after breast cancer, focusing on changes of the fee-per-case system in the last 6 years. Immediate, delayed, pedicle and free flaps as well as alloplastic reconstructive methods were analysed using data from German reference hospitals. We analysed the length of stay, reimbursements, costs and profits. The biggest profit margin was found in free perforator flaps. These were up to 3 times higher than in alloplastic reconstruction and pedicle flaps. Due to the fact that the underlying costs for the calculation of reimbursement are always retrospective, we accounted for the rate of price increase. In spite of increasing mean profits, foregone profits of up to €574 per case due to inflation were not taken into consideration. Contrary to actual guidelines, neither the immediate reconstruction of the breast by autologous tissue, nor the bilateral reconstruction is taken into account economically. Although a more differentiated reimbursement of breast reconstruction by DRG has taken place in the last years, the subject still remains a classical example for insufficient mapping of new medical standards in our DRG system. As the choice of surgical therapy is increasingly influenced by free market mechanisms, the risk for economic selection in contradiction to clinical recommendations becomes a real problem. Even 9 years after its introduction, the German DRG system is far from being a learning or quick adapting system.

Economic Impact of Infected Total Knee Arthroplasty

Background. An enormous economic impact can be observed for infected total knee arthroplasties (TKA). The aim of the present study was to evaluate whether a cost covering treatment of infected TKA is feasible in the German DRG System. Patients and Methods. Average total treatment costs were evaluated for infected TKA and compared with a matched pair of primary TKA. Data was generated using the health record and the hospitals' health information system. Results were evaluated and compared regarding the total personnel and material costs with respect to the financial receipts. Results. A total of 28 patients diagnosed with an infected TKA were included. A significant increase in the average length of stay, use of medical supplies and third party medical examinations were found for the infected TKA. An average deficiency of 6,356€ per patient was observed for the infected TKA. An average profit of 927€ per patient was made performing primary TKA. Conclusions. A cost-effective treatment of infected TKA was not feasible with the receipts from the German DRG System. An adaption of the receipts has to be evaluated. Moreover, other measures have to be considered in order to achieve a comprehensive medical yet financial reasonable standard in the treatment of infected TKA and THA.

Kosten- und Leistungsheterogenität bei penetrierenden Augenverletzungen und Amnionmembranaufnähungen unter DRG-Bedingungen

Patients with penetrating eye injuries are a very heterogeneous group both medically and economically. Since 2009, treatment involving sutures for open eye injuries and cases requiring amniotic membrane transplantation (AMT) were allocated to DRG C01B of the German diagnosis-related group system. However, given the significant clinical differences between these treatments, an inhomogeneity of costs to performance is postulated. This analysis describes case allocation problems within the G-DRG C01B category and presents solutions.A retrospective analysis was conducted from the standardized G-DRG data of 277 patients with open eye injuries and AMT between 2007 and 2008, grouped under the 2008 G-DRG system version to the G-DRG C01Z category. This data was provided by the Department of Ophthalmology at the University Hospital Regensburg. Additionally case-based data of the following were supplemented: length of surgery, time of anesthesia and intensity of patient care. Fixed and variable costs were determined for surgery and other inpatient treatment. Finally, an analysis of the heterogeneity of costs within the G-DRG C01B of the G-DRG system 2009 was implemented.Inhomogeneity was evident within the G-DRG C01B of the G-DRG system 2009 for the two groups suture of open eye injuries and AMT concerning the parameters length of stay, proportion of high outliers and cost per case. Multiple surgeries during an inpatient stay lead to an extended length of stay and increasing costs, especially within the AMT group. Intensity of patient care and the consideration of patient comorbidity did not yield relevant differences.The quality of the G-DRG system is measured by its ability to obtain adequate funding for highly complex and heterogeneous cases. Specific modifications of the G-DRG structures could increase the appropriateness of case allocation for patients with open eye injuries within the G-DRG C01B of the German DRG system 2009. As a result of the present study, cases with amniotic membrane transplantation should not be allocated to the G-DRG C01B. A petition has been presented by the German Association of Ophthalmology (DOG) to the German DRG Institute to restructure the G-DRG C01B. Data-based analysis is an essential prerequisite for a constructive development of the G-DRG system and a necessary tool for the active participation of medical societies in this process.

Diagnosis-Related Groups (DRGs) are a patient classification system grouping related types of patients to the resources they have consumed. In this analysis, we compared pedicle and free flaps in plastic and reconstructive surgery in the actual German DRG system. After grouping common flaps while systematically modifying the diagnosis, the operative procedure(s), and the receptor site, reimbursement and thresholds of length of stay were identified. The mean value of the average length of stay was higher in free flaps as compared to pedicle flaps (15 vs. 9 days) and the mean reimbursement in free flaps was almost twice as high as in pedicle flaps (8 936 € vs. 4 582 €). Regarding the diagnosis, third-grade open fractures in pedicle flaps and full-thickness burns in free flaps are in the vanguard of reimbursement. Higher DRG conformity is generally found with free flaps. Different possibilities in coding the procedures and the strong dependence on the underlying diagnosis lead to variations of remuneration and length of stay, which are not explainable and sometimes even seem paradoxical. Furthermore, mixed calculation creates DRGs that lose the ability to describe the real effort.

Cost effectiveness of total knee arthroplasty from a health care providers' perspective before and after introduction of an interdisciplinary clinical pathway - is investment always improvement?

BackgroundTotal knee arthroplasty (TKA) is an effective, but also cost-intensive health care intervention for end stage osteoarthritis. This investigation was designed to evaluate the cost-effectiveness of TKA before versus after introduction of an interdisciplinary clinical pathway from a University Orthopedic Surgery Department's cost perspective as an interdisciplinary full service health care provider.MethodsA prospective trial recruited two sequential cohorts of 132 and 128 consecutive patients, who were interviewed by means of the WOMAC questionnaire. Direct process costs from the health care providers' perspective were estimated according to the German DRG calculation framework. The health economic evaluation was based on margiual cost-effectveness ratios (MCERs); an individual marginal cost effectiveness relation ≤ 100 € per % WOMAC index increase was considered as primary endpoint of the confirmatory cohort comparison. The interdisciplinary clinical pathway under consideration primarily consisted of a voluntary preoperative personal briefing of patients concerning postoperatively expectable progess in health status and optimum use of walking aids after surgery. All patients were supplied with written information on these topics, attendance of the personal briefing also included preoperative training for postoperative mobilisation by the Department's physiotherapeutic staff.ResultsAn individual marginal cost effectiveness relation ≤ 100 €/% WOMAC index increase was found in 38% of the patients in the pre pathway implementation cohort versus in 30% of the post pathway implementation cohort (Fisher p = 0.278). Both cohorts showed substantial improvement in WOMAC scores (39 versus 35% in median), whereas the cohort did not differ significantly in the median WOMAC score before surgery (41% for the pre pathway cohort versus 44% for the post pathway cohort). Despite a locally significant decrease in costs (4303 versus 4194 € in median), the individual cost/benefit relation became worse after introduction of the pathway: for the first cohort the MCER was estimated 108 € per gained % WOMAC index increase (86 - 150 €/%) versus 118 €/% WOMAC gain (93 - 173 €/%) in the second cohort after pathway implementation. In summary, the proposed critical pathway for TKA could be shown to be significantly cost efficient, but not cost effective concerning functional outcome, when the above individual marginal cost effectiveness criterion was concentrated on.ConclusionsThe introduction of an interdisciplinary clinical pathway does not necessarily improve patient related outcomes. On the contrary, cost effectiveness from the health care providers' perspective may even turn out remarkably reduced in the setting considered here (functional outcome assessment after treatment by a full service health care provider).

„Treat-to-Target“ (T2T) aus der Sicht der stationären Rheumatologie

Publication of the treat-to-target (T2T) concept at the end of the Bone and Joint Decade almost coincided with the 15 treatment recommendations of the EULAR as well as with the new classification and revised remission criteria for rheumatoid arthritis (RA).The treat-to-target initiative is solely focused on the description of benchmarks for an effective treatment management of RA to reach its priority target of remission.From the perspective of inpatient rheumatology parallels are shown to the quality projects of the Association of Rheumatology Clinics (VRA), which were initiated in 2001 for the first time.The quality management started up by the VRA not only benefited from the development of the German diagnosis-related groups (G-DRG) system which was also supported by the VRA and the German Society of Rheumatology (DGRh) but also from projects realized to improve the structural and operational quality in inpatient rheumatology units.By launching its own outcome benchmarking project (OBRA) in 2003, which was financially supported by the German Ministry of Health and its continuation with Kobra-1 and future Kobra-2, the VRA already successfully incorporated all benchmarks of management guidelines outlined in the T2T initiative.By steadily improving the outcome, even of RA patients, inpatient rheumatology offers a special quality project for participating clinics who are otherwise competitors, not only to learn from each other but to support each other to find the best way (T2T) to reach a remission and a good quality of life for RA patients and patients with other systemic rheumatic diseases.

Finanzierung der stationären Orthopädie und Unfallchirurgie im G-DRG-System 2011

The German DRG system forms the basis for billing inpatient hospital services. It includes not only the case groups (G-DRGs), but also copayments. This paper analyses and evaluates the relevant developments of the 2011 G-DRG system for orthopaedics and traumatology from the medical and classificatory perspective. An analysis was performed of relevant diagnoses, medical procedures and G-DRGs in the 2010 and 2011 versions based on the publications of the German DRG Institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). A number of codes for surgical measures have been newly established or modified - above all in foot surgery, arthroscopic surgery and wound surgery. Here, the identification and the correct and performance-based mapping of complex and elaborate scenarios was again the focus of the restructuring of the G-DRG system. The G-DRG structure in orthopaedics and traumatology is changed, especially for polytraumata. The allocation of common cases with a standardized treatment pattern appears to be appropriate and the reimbursement adequate. For the less common and more complex cases the 2011 G-DRG system still shows need for further modification (e.g. polytraumata, joint replacement, spine surgery). The proper integration of the modified OPS classification for foot surgery to the appropriate G-DRGs will be essential to maintain the high quality of the reimbursement structure for the future.

Vergleich der Handchirurgie im österreichischen und deutschen Fallpauschalensystem

Diagnosis-Related Groups (DRG) are a patient classification system grouping related types of patients treated to the resources they consumed. In this analysis, we compared the Austrian and the German DRG systems. The 15 most common hand surgical diagnoses and their corresponding operative treatment were transferred into the Austrian system. Thus, the length of stay and the reimbursement of both countries could be obtained and compared. The mean values and the median values of the upper and lower thresholds of length of stay as well as the average length of stay were all lower in Austria compared to Germany. Reimbursement in Germany was higher in 13 of 19 cases. Total proceeds amounted to 1.67 million <euro> in the German and 1.70 million <euro> in the Austrian health care system. Considering the purchasing power applying consumer prize parities, the difference of reimbursement between the countries rose to 130,000 <euro> which equals a difference of almost 8%. Reimbursement of the top 15 diagnoses in hand surgery in Austria is 8% higher than in Germany. Except for one case, mean values as well as upper and lower thresholds of length of stay are considerably shorter in Austria. Comparison of international data to refine a national compensation system is advocated.

Surgical Management of Congenital Heart Disease: Contribution of the Aristotle Complexity Score to Planning and Budgeting in the German Diagnosis-Related Groups System

Planning and budgeting for congenital heart surgery depend primarily on how closely reimbursement matches costs and on the number and complexity of the surgical procedures. Aristotle complexity scores for the year 2010 were correlated with hospital costs and with reimbursement according to the German diagnosis-related groups (DRG) system. Unit surgical performance was estimated as surgical performance (complexity score × hospital survival) times the number of primary procedures. This study investigated how this performance evolved during years 2006 to 2010. Hospital costs and reimbursements correlated highly with Aristotle comprehensive complexity levels (Spearman r = 1). Mean costs and reimbursement reached 35,050<euro> ± 32,665<euro> and 31,283<euro> ± 34,732<euro>, respectively, for an underfunding of 10.7%. Basic and comprehensive unit surgical performances were respectively 3036 ± 1009 and 3891 ± 1591 points in 2006. Both performances increased in sigmoid fashion to reach 3883 ± 1344 and 5335 ± 1314 points, respectively, in 2010. Top performances would be achieved in year 2011, and extrapolated costs would comprise about 19,434,094.92<euro> (95% confidence interval, 11,961,491.22-22,495,764.42<euro>). The current underfunding of congenital heart surgery needs correction. The Aristotle score can help to adjust reimbursement according to complexity of procedures. Unit surgical performance allows accurate budgeting in the current German DRG system.

The Early Rehabilitation Barthel Index (ERBI)

An extended version of the Barthel index, the so-called "Early Rehabilitation Barthel Index", or ERBI, is widely used in German early neurological rehabilitation centres and even was used in defining early rehabilitation procedures in the German DRG system. It contains highly relevant items like mechanical ventilation, tracheostomy, or dysphagia. This study presents an English version of the ERBI and examines its validity and reliability. Two samples of early neurological rehabilitation patients have been analyzed. In one sample (n=1,669), measures of morbidity and length of stay (LOS) have been compared between certain ERBI categories. In a second sample (n=273), inter-rater reliability (nurses vs. physicians) has been examined. Patients with low ERBI had a significantly longer LOS than those with high ERBI values (p<0.001). Further, parameters of morbidity (patient clinical complexity level, number of co-diagnoses) were significantly higher in a low ERBI subgroup. Inter-rater reliability was r=0.849 (p<0.001). The findings suggest that the ERBI is a reliable and valid scale to assess early neurological rehabilitation patients.

Drug-related admissions and hospital-acquired adverse drug events in Germany: a longitudinal analysis from 2003 to 2007 of ICD-10-coded routine data.

BackgroundAdverse reactions and medication errors are complications of drug use. Spontaneous reporting systems and pharmacoepidemiological studies incompletely detect the occurrence of these events in daily hospital care. In this study, the frequency and type of drug-related admissions and hospital-acquired adverse drug events (ADE) in Germany were assessed using routinely collected hospital data.MethodsThe study was based on aggregated hospital routine data covering the period 2003 to 2007 and annually recorded as part of the further development of the German Diagnosis-Related Groups. The 505 ICD-10-codes indicating an ADE were categorized in seven groups according to their certainty. Primary diagnoses were considered as a proxy for drug-related admissions, and secondary diagnoses as a proxy for hospital-acquired ADE.ResultsAmong all hospital admissions, 5% were found to be at least possibly drug-induced and 0.7% very likely drug-induced. There was a significant increase in the overall rate of drug-related admissions over time (p < 0.038). Enterocolitis due to Clostridium difficile infection was the most frequent cause of a drug-related admission. About 4.5% of in-patients had experienced a hospital-acquired ADE. In addition, over the course of the study period, the overall frequency of hospital-acquired ADEs significantly increased (p < 0.001).ConclusionsIn Germany, more than 5% of hospital episodes are either caused or complicated by an ADE. Between 2003 and 2007, there was a statistically significant increase in the overall rate and in some of the subcategories defined by the list of ICD-10-codes suspected to be indicative of an ADE. Before the use of routine data in pharmacovigilance and patient safety can be fully exploited, a further tailoring of both the ICD and the available variable set is needed.

Elzacher Konzept und Leistungskatalog der therapeutischen Pflege in der neurologischen Frührehabilitation (Phase B)

The German DRG system defines specialized treatments through a set of minimal requirements, the documentation of which and its assessment by external specialists of the medical service of the statutory health insurance causing frictions between rehabilitation hospitals and the medical service. It is especially problematic to make a clear distinction between nursing care and treatment. To reduce frictions and interface problems, a catalogue of acts of therapy performed by nurses was agreed for neurological early rehabilitation in Baden-Württemberg. This Elzach concept and catalogue describe therapeutic nursing in neurological rehabilitation and increase transparency and accountability both for providers and cost carriers.
