RESUMO
OBJECTIVE: In projects on early intervention, a wide variety of instruments is used for the measurement of intervention effects on preservation or restoration of ability to work. The aim of the present work was to propose an appropriate instrument or a range of appropriate instruments that enable diverse interventional approaches to be compared, and data quality to be improved. METHODS: A systematic literature search was conducted to map the currently existing measuring instruments. In addition, based on structured interviews with leaders of existing early intervention projects or representatives of other interventional approaches, knowledge and application of the measuring instruments in Germany were determined. In the context of a working meeting, a recommendation was formulated based on the results of the literature search and interviews. RESULTS AND COMMENTS: There is currently no instrument that could be recommended without reservation for the stated purpose. Based on the results of the literature search and the interviews, the working group recommends using, as a first step, the Work Ability Index (WAI, focus on work ability) and the Work Productivity and Activity Impairment Questionnaire (WPAI, focus on absenteeism and presenteeism). German-language versions of both questionnaires are freely available and offer a good compromise in terms of psychometric quality criteria, as well as of practicality and applicability. The measuring instruments should be developed further, with the goal of establishing an optimized instrument that combines the strengths of the two instruments. CONCLUSION: In Germany, use of WAI and the WPAI in as many early intervention approaches as possible will help improve the database, allowing better comparability. However, the focus of further research must be to develop an optimized instrument from elements of WAI and WPAI, in order to be able to measure ability to work as well as the effects of an intervention on preservation or restoration of the ability to work, regardless of the setting.

OBJECTIVES: To examine the costs of inpatient and outpatient rehabilitation for musculoskeletal disorders from the perspective of a major statutory health insurance fund in Germany. METHODS: A nation-wide database from a major health insurance fund in Germany was used to evaluate all rehabilitation cases in 2005. In addition, to all direct cost domains of the rehabilitation itself, costs incurred in the preceding and the following year for hospital treatment, drugs and physical therapy were analysed. A cost-cost analysis in different institutional settings was chosen for the cost comparison of inpatient and outpatient rehabilitation. To minimize the influence of possible confounders, a statistical control system was implemented. RESULTS: After a preceding hospital stay, inpatient and outpatient rehabilitation results in mean costs of euro2047 and euro1111, respectively. If the rehabilitation was not preceded by a directly related hospital treatment, mean costs for inpatient (outpatient) rehabilitation were euro2067 (euro1310). No systematic differences could be found between inpatient and outpatient rehabilitation evaluating costs for hospital treatment, drugs or physical therapy in the year preceding and the year directly following the rehabilitation. CONCLUSIONS: Assuming comparable medical outcomes, outpatient rehabilitation seems to be a superior alternative compared with inpatient rehabilitation from an economic perspective. Hence, from the perspective of the statutory health insurance, fostering a higher market share of outpatient rehabilitation may add to a better allocation of overall health care resources. For this, regional differences in rehabilitation infrastructure have to be taken into account.

Early arthritis is challenging because the clinical picture often does not allow a distinction between rheumatoid arthritis (RA), self-limiting disease, and other forms of inflammatory arthritis. In Germany the first early synovitis clinic and several inception cohorts of patients with early RA were initiated and evaluated during the 1980s and 1990s to learn more about diagnostic classification, psycho-social problems and socio-economical status including sick-leave, work loss, and indirect costs of patients with early arthritis and early RA. Unclassified arthritis was described as the most frequent diagnosis and the term "undifferentiated arthritis" was chosen to underline the heterogeneity of theses arthritides and the preliminary state of this classification as a working diagnosis. A large National Databank of the German Regional Collaborative Arthritis Centres has been established over the last 10 years. In total, there are some 170,000 cases in the database. Moreover, a prospective multicentre inception cohort of early RA of less than 1 year's disease duration has been started recently to evaluate parameters of potential relevance for the pathogenesis of RA and eventually for the prediction of erosive disease. Studies are in progress to test the diagnostic performance of specific antibodies and antibody patterns for RA. Another topic of research addresses the identification of bacterial DNA in synovial fluid and synovial tissues to improve the differentiation of patients with reactive arthritis from those with early RA and to narrow the working diagnosis of undifferentiated arthritis.

We present a matrix of relevant resource utilization domains for use in standardizing applied cost assessment in musculoskeletal conditions. In addition,we highlight the importance of selecting cost categories during the development of an economic evaluation. A set of four steps was applied: (a) literature search identifying economic evaluations in osteoarthritis and osteoporosis, (b) listing and aggregation of cost categories mentioned in the identified articles, (c) development of a matrix of resource utilization domains, and (d) qualitative discussion regarding the generalizability of the matrix to other musculoskeletal conditions such as rheumatoid arthritis. We examined 41 full-length articles (25 cost-of-illness studies or cost-comparisons, 14 cost-effectiveness analyses, and 2 cost-utility analyses), of which 16 studies focused on osteoarthritis and 25 on osteoporosis. The reviewed studies used a total of 151 different cost categories which, after adjustment for synonymous labeling, made up 34 cost categories. A matrix of 16 separate resource utilization domains was developed including seven outpatient, three inpatient, four other disease-related, and two productivity cost domains. We found that cost assessment in economic evaluation in the key musculo-skeletal diseases (osteoarthritis, osteoporosis, and rheumatoid arthritis) is performed rather inhomogeneously. A generalized matrix of applicable resource utilization domains and a flowchart facilitating the development of appropriate resource utilization data have been developed.
RESUMO
OBJECTIVE: To estimate and compare the direct and indirect costs of illness in rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis (PsA) and systemic lupus erythematosus (SLE), and to evaluate the effect of sex, disease duration and functional status on the various cost domains. METHODS: Data of outpatients, aged 18-65, with rheumatoid arthritis (n = 4351), ankylosing spondylitis (n = 827), PsA (n = 908) or SLE (n = 844), who were enrolled in the national database of the German collaborative arthritis centres in 2002, were analysed. Data on healthcare consumption, out-of-pocket expenses and productivity losses were derived from doctors and patients. For the calculation of indirect costs, the human capital approach (HCA) and the friction cost approach (FCA) were applied. RESULTS: Mean direct costs amounted to 4737 euros a year in rheumatoid arthritis, 3676 euros in ankylosing spondylitis, 3156 euros in PsA and 3191 euros in SLE. By using the HCA, total costs were calculated at 15,637 euros in rheumatoid arthritis, 13,513 euros in ankylosing spondylitis, 11,075 euros in PsA and 14,411 euros in SLE, whereas with the FCA the numbers were 7899 euros, 7204 euros, 5570 euros and 6518 euros, respectively. Costs increased with disease duration and were strongly dependent on functional status. In patients with the highest disability (<50% of full function), the total costs on applying the HCA were 34,915 euros in rheumatoid arthritis, 29,647 euros in alkylosing spondylitis, 37,440 euros in PsA and 32,296 euros in SLE. CONCLUSION: The costs of illness are high in all four diseases, with a strong effect of functional status on total costs. Indirect costs differ by the factor 3, based on whether the HCA or the FCA is used.

OBJECTIVE: Identification of predictors for the productivity cost components: (1) sick leave, and (2) work disability in gainfully employed and (3) impaired household productivity in unemployed patients with rheumatoid arthritis (RA) from the societal perspective. METHODS: Investigation of productivity costs was linked to a multicenter, randomized, controlled trial evaluating the effectiveness of clinical quality management in 338 patients with RA. The productivity losses were assessed according to the German Guidelines on Health Economic Evaluation. By means of multivariate logistic regression analyses, predictors of sick leave, work disability (employed patients, n=96), and for days confined to bed in unemployed patient (n=242) were determined. RESULTS: Mean annual costs of 970 EUR arose per person taking into consideration all patients (453 EUR sick leave, 63 EUR work disability, 454 EUR impaired productivity of unemployed patients). Disease activity, disease severity, and impaired physical function were global predictors for all of the cost components investigated. Sick leave costs were predicted by prior sick leave periods and the vocational status blue collar worker, work disability costs by sociodemographic variables (marital status, schooling), and the productivity costs of unemployed patients by impaired mental health and impaired physical functions. CONCLUSIONS: Interventions such as reduction in disease progression and control of disease activity, early vocational rehabilitation measures and vocational retraining in patients at risk of quitting working life, and self-management programs to learn coping strategies might decrease future RA-related productivity costs.

OBJECTIVE: To determine rheumatoid arthritis related out of pocket expenditure (OOPE) in Germany and to disaggregate the total OOPE into contributing cost domains. METHODS: Data for the cost analysis were drawn from a multicentre randomised controlled prospective trial to assess the effectiveness of clinical quality management in patients with rheumatoid arthritis. Both payer sources and patient cost questionnaires were used to generate health care utilisation data. All cost domains of a recently published matrix were reviewed and potential sources of OOPE were determined. Health care utilisation data were developed throughout 2001. Co-payment regulations as per January 2004 were applied in order to indicate the most recent level of OOPE in Germany. Data were analysed in both physical and monetary units using descriptive statistics. RESULTS: In all, 136 patients with rheumatoid arthritis were included. Mean total OOPE per patient and year was 417.20 Euro (SEM 38.8, median 271.2). OOPE accounted for 15.3% of the total direct costs of rheumatoid arthritis. Total OOPE were further subdivided into cost domains: "non-physician service utilisation"' (194.40 Euro per patient and year; SEM 24.2), "medication" (99.00 Euro; 6.1), "transportation" (56.20 Euro; 17.4), "visits to physicians" (38.40 Euro; 0.6), "hospital facilities" (24.00 Euro; 5.6), and "devices and aids" (5.10 Euro; 0.8). CONCLUSIONS: Rheumatoid arthritis is associated with substantial OOPE, imposing a considerable economic burden for patients. OOPE contribute significantly to the total health care expenditure in rheumatoid arthritis. The patient perspective has to be taken into account when calculating the overall direct costs of rheumatoid arthritis from a societal point of view.

This study examines the applicability of the questionnaire "Fragebogen zur Erhebung von Kontrollüberzeugungen zu Krankheit und Gesundheit - KKG" to patients with early course of rheumatoid arthritis (RA) or undifferentiated Arthritis (uA), and the relationship between the severity of the disease and locus of control by controlling for socio-demographic variables and personality characteristics. 326 patients with early RA or uA with a disease duration of less than 12 months (mean disease duration 6 months +/- 3.5, mean age 53 +/- 14) were assessed. Full clinical investigations were performed and patients questionnaires were administered at the outset of the study (T1), after 12 months (T2) and after 24 months (T3). The factor-solution of the KKG-questionnaire in patients with early course of RA/uA is not different from healthy controls. A marked influence on coping types can be demonstrated for the covariates sex, age, cognitive components of anxiety and the severity of RA. These results should be considered in education programs for RA applying special techniques of behaviour therapy. Such interventions in the early phase of RA might lead to a reduction of cognitive anxiety and thus to more active coping in patients with RA.

OBJECTIVES: Work disability (WD) in early rheumatoid arthritis (RA) has not been extensively evaluated in Germany. Therefore, the occurrence of WD pension within the first seven years of RA and prognostic indicators of the first year including the duration of sick leave (SL) were analyzed. PATIENTS AND METHODS: Within the first year of RA according to the ACR 1987 criteria, 141 gainfully employed patients were entered into a prospective multicenter study (61% females, mean age 47 +/- 9 years, mean disease duration 6 +/- 3.5 months). One hundred and ten patients (78%) participated in a reevaluation (postal questionnaire) after a mean follow-up of 6.1 +/- 0.4 years. Predictors of WD pension were identified in univariate analyses and in backward multivariate Cox regression analyses (p < 0.05) with Hazard-ratios [H-R] as measures of WD risk. RESULTS: Of 110 patients 53 (48%) were still employed at reexamination. WD due to RA occurred in 5% after one year disease duration, in 15% after 2 years, in 20% after 3 years, and in 28% after 6.5 years. Other reasons for leaving the labor force were found in 24%. High pain intensity, radiographic erosions, comorbidity and the pain behavior of avoidance were associated with WD only in univariate analyses. Age > 45 years [H-R 6.3] and the following job-related prognostic indicators were identified in the multivariate analyses: working under pressure of time [H-R 9.0], limited joint motion interferring with job tasks [H-R 5.9], feeling overworked [H-R 3.8] and work status (unskilled blue-collar workers vs white-collar professionals and self-employed persons) [H-R 3.4]. In an alternative final Cox-regression model the variables feeling overworked and work status were replaced by SL duration > 8 weeks within the first year of RA [H-R 7.1]. CONCLUSIONS: Since WD frequently occurs already within the first 3 years (20%) adequate interventions resulting from the prognostic indicators have to begin early in the course of RA. Apart from the rheumatological treatment and rehabilitation focusing on the reduction of pain, improved coping with pain, reduced joint destruction and improved mobility particularly working under pressure of time should be avoided and the work place has to be adjusted in case of limited joint motion interferring with job tasks. SL of several weeks duration already within the first year of RA is a red flag for impending WD.

UNLABELLED: In a one-year prospective study of patients participating in a multidisciplinary outpatient or inpatient rehabilitation program (OPR/IPR) for chronic back pain the following issues were investigated: (i) the frequency of low labour force participation (LFP), i. e., work loss due to the disease or total duration of sick leave (SL) of 6 weeks or more; (ii) prognostic indicators at the beginning of the rehabilitation program (T1) for low LFP after one year (T2); (iii) the significance of the type of rehabilitation IPR vs. OPR in relation to the identified prognostic indicators for LFP. A total of 413 patients participating in OPR (n = 299) or IPR (n = 114) for chronic back pain returned a postal questionnaire after one year. Low LFP was found in 30 % of all patients without significant differences between OPR (32 %) and IPR (25 %). Compared to the year before T1 the proportion of patients without SL between T1 and T2 increased from 12 % to 48 % after OPR, from 15 % to 47 % after IPR, respectively. In multivariate logistic regression analyses adjusted for type of rehabilitation the following prognostic indicators of T1 for low LFP were identified (p = 0,05): SL of 6 weeks or more in the year before T1 with an odds ratio (OR) of 11.1; intended termination of employment (OR = 3.2), household income of less than 3300 DM per month (OR = 2.2); reduced social functioning (SF-36) (OR = 2.0). Regarding LFP no significance of the type of rehabilitation (IPR vs. OPR) was found in relation to the identified prognostic indicators or after adjustment for differences (i) in the characteristics of the patients at T1, and (ii) in the duration and number of single measures of the rehabilitation program. CONCLUSIONS: One year after IPR or OPR the rate of return to work is similar (about seven out of ten patients). The identified prognostic indicators may stimulate further research of the improvement of the rehabilitation processes. No evidence was found against the expansion of OPR.

The present economic analyses of orthopaedic inpatient and outpatient rehabilitation (IPR resp. OPR) focus but on the evaluation of the expenses from the cost carrier's perspective. Lower intervention costs were related to OPR, whereas comparable social and clinical outcome was achieved. Comprehensive assessment of the economic consequences (resource utilization and lost productivity) of low back pain have not been performed up to now. Therefore, as part of a prospective follow-up study (1) a comparison of overall cost-of-illness and cost components 12 months prior and after IPR and OPR, respectively, was carried out in patients with low back pain and (2) the relative changes of these cost components were compared in a full-cost-analysis from a societal perspective. A total of 150 matched pairs (SR and AR) were followed prospectively over 12 months. Disease related costs in the year prior to the intervention were evaluated retrospectively. Prior to IPR and OPR overall costs amounted to 7010 and 7710 Euro, respectively, per person and year in patients with low back pain. As the main cost component of overall costs, sick leave (SL) periods account for 74% (IPR) and 76% (OPR), respectively. Inpatient costs represent the main component of direct costs. In the year after the intervention the costs due to sick leave periods still represent the major cost component (46 and 52%, resp.) of overall costs (3370 and 3600 Euro, resp.). Disease related cessation of work including work disability accounts for about 10% of productivity costs after IPR and OPR. Indirect costs still make up for the major part of overall costs (58 and 62%, resp.). No differences of cost components and their relative changes can be seen between patients participating in IPR and OPR, respectively, within both time frames. The comparison of overall costs in the 12 months before and after IPR and OPR reveals a cost reduction of 52% (IPR) and 53% (OPR), resp. This decrease of costs is mainly related to the reduction of SL periods, though costs due to inpatient treatment decrease as well. Summarizing, the present full-cost-analysis from a societal perspective shows no differences of cost components and cost changes between orthopaedic IPR and OPR in the 12 months prior to and after the intervention. Comprehensive cost-analyses reveal no obstacles for further implementation of OPR in the treatment of low back pain. Future development and diversification of rehabilitation measures should aim at evaluating real resource consumption during the intervention in detail as a basis for further allocational decision making.

OBJECTIVE: To investigate 1) the magnitude of indirect costs, 2) changes in cost components, and 3) correlations between changes in cost and social, clinical, and occupational variables within the first 3 years of rheumatoid arthritis (RA). METHODS: We evaluated the indirect costs per person-year in 133 consecutive gainfully employed out-patients with early RA, in a prospective multicenter followup study. Costs due to RA-related sick leave, work disability, and other work loss were assessed using the human capital approach. Variables associated with reduction in lost productivity were tested by multivariate logistic regression analysis. RESULTS: Mean +/- SEM annual indirect costs were $11,750 +/- 1,120 per person. During the 3-year period of observation, a marked reduction in the costs associated with sick leave was seen, which exceeded the increase in costs due to work disability and other work loss. This phenomenon resulted in an overall reduction in indirect costs of 21%. The final logistic regression model of reduced loss of productivity included 3 variables: no problems with standing (odds ratio [OR] 7.1), no problems with working speed (OR 4.1), and no problems with outdoor work (OR 3.1). CONCLUSION: High indirect costs in early RA were demonstrated. An overall decrease of costs can be seen in the first 3 years, due to the reduction in sick leave. Since the absence of problems due to strenuous working conditions was found to be associated with a reduction in indirect costs, it is assumed that early intensified vocational rehabilitation, apart from controlling disease activity by adequate treatment, might help to reduce indirect costs.

Costs of illness are of major economic relevance in rheumatoid arthritis (RA) as in other chronic diseases. Overall costs of 15,000 Euro/year: 10,000 Euro indirect costs, and 5000 Euro direct costs are estimated, respectively. A further detailed analysis of direct costs underlines that inpatient care (50%) is the most prominent cost driver. Medication costs are also evaluated in detail since they are expected to gain importance with the introduction of the more expensive biologicals. While annual costs for regular disease modifying drugs (DMARDs) vary from 160 to 5000 Euro per patient, costs for the new biologicals amount up to 20,000 Euro (100-125% of the current estimated overall costs). For a comparison of different therapeutic strategies, costs are related to effectiveness in cost-effectiveness analyses. Based on present clinical trials, the ratios of medication costs and response according to the ACR 20-criteria of various DMARDs and biologicals are compared. The most cost-effective medication is sulfasalzine, followed by methotrexate, and leflunomide. Combining etanercept and methotrexate is preferable to methotrexate monotherapy and the combination of infliximab and methotrexate. This review shows that important economic issues in RA have already been addressed by applying cost-of-illness analyses and cost-effectiveness analyses. However, the knowledge about cost-effective therapeutic options is still scarce. Thus, primary data will have to be obtained using standardized approaches. These economic findings can be taken into account in the development of disease-management recommendations for RA-therapy.

The comparison of patient characteristics and effectiveness of inpatient rehabilitation (IPR) and outpatient rehabilitation (OPR) is of growing importance in terms of flexible and cost-effective structures in rehabilitation. The effectiveness of the treatment is measured applying a goaloriented approach based on the individual rehabilitation goals and the attainment of these goals at the end of the programme. The frequencies of rehabilitation goals chosen by patients in IPR and OPR are similar. Decrease of pain, improvement of muscular strength and improvement of the range of motion are the main goals of patients in IPR and OPR (92-56%). No relevant differences can be seen considering the effectiveness of IPR and OPR, except for the markedly higher improvement of vitality in IPR. Patients in need of rehabilitation whose primary rehabilitation goal is improvement of vitality should therefore preferentially be referred to an inpatient rehabilitation programme.

Cost-of-illness studies in rheumatic conditions show an enormous variability in reported costs. Reasons are-among others-a lack of standardization with regards to relevant cost domains and the utilization of various insufficiently validated costing sources. A flow scheme is presented which may serve as a systematic basis for a valid costing analysis. The scheme includes: i) Selection of relevant cost domains. A comprehensive matrix of cost domains may be used as a framework. According to the specific aims of any costing study individual domains might be selected. ii) An adequate level of detail has to be determined taking into account factors such as the validity of the data collection and the feasibility. iii) Appropriate objective (i. e. usage of administrative data) or subjective (i. e. patient-derived) data sources have to be identified under consideration of respective strengths and weaknesses. While administrative sources provide a valid access to costing data accessibility and feasibility are important advantages of patient-derived costing procedures. iv) During data collection the potential bias due to protocol-driven costs and the differentiation of disease-related from other health care costs should be considered. v) The data analysis should support a transparent presentation of the costing data both in physical and monetary units. In summary, no 'gold standard' has been established for costing studies yet. However, valid costing approaches might follow the flow scheme presented in this analysis.

The aim of our study was to comprehensively review and critically appraise the cost domains used in economic evaluations of the rheumatic diseases and to use this information to propose standardization of cost domains. The literature search identified 210 abstracts, 32 of which included original cost data. The listed cost categories were grouped into 3 major areas: (direct) health care costs, other (direct) disease related costs, and productivity costs (indirect costs). The number of individual cost categories was reduced by considering the following criteria: (1) inclusion of all relevant cost domains; (2) avoidance of double counting; (3) summarizing of related categories under one representative heading; (4) feasibility of level of aggregation. After adjustment for synonymous labeling, 38 cost categories remained. The subsequent development of a classification scheme of cost categories led to a set of 19 separate cost domains including 7 outpatient, 3 inpatient, 6 other disease related, and 3 productivity cost domains. This literature review indicates that cost assessment in economic evaluations in rheumatoid arthritis lacks standardization. A preliminary scheme to categorize cost assessment in rheumatic conditions is presented. The adoption of standards for economic evaluation would greatly facilitate national and international comparisons.

We compared the major characteristics of internationally applied cost assessment instruments (CAI) in rheumatic conditions. Fifteen utilization questionnaires were identified and assessed using a structured approach. The forms differed considerably with respect to applied characteristics: length (3-113 items), recall period (between 1 week and 1 year), format (2 interview, 13 self-administered), response categories, cost units (physical vs monetary), and cost domains covered. While all included a gross assessment of outpatient and inpatient costs, the level of disaggregation differed. Only a few CAI included an assessment of other direct disease related costs (e.g., home remodeling or home health care services) and out-of-pocket expenditure. Productivity costs were included in all but 2 CAI. Efforts to further standardize the applied CAI should (1) be based on sound psychometric data, (2) define a required core set of cost domains covered, (3) discriminate between generic and relevant disease related cost components, and (4) examine the feasibility of developing international standards for cost data.

OBJECTIVE: To develop a systematic set of German cost data in rheumatoid arthritis (RA) based solely on valid healthcare payer's cost data sources. METHODS: Retrospectively one year cost data of 338 patients with RA were generated and analysed. The cost data were derived from a major statutory health insurance plan ("Allgemeine Ortskrankenkasse Niedersachsen") and the regional physicians' association ("Kassenärztliche Vereinigung Niedersachsen"). The recently published matrix of cost domains in RA was applied to structure the analysis. Descriptive statistics were used to analyse the data. RESULTS: The total direct costs for the 338 patients during one year (third quarter 2000 to second quarter 2001) were euro 3815 per patient-year. RA related direct costs were euro 2312 per patient-year. Outpatient costs accounted for 73.7%, inpatient costs for 24.0%, and other disease related costs for 2.3% of RA related direct costs. Outpatients cost drivers were RA related drugs (euro 1019 per patient-year), physician visits (euro 323 per patient-year), diagnostic and therapeutic procedures and tests (euro 185 per patient-year), and devices and aids (euro;168 per patient-year). 98 patients were retired prematurely owing to RA related work disability and incurred costs of euro;8358 per retired patient-year. 96 patients were gainfully employed and incurred sick leave costs of euro 2835 per employed patient-year. CONCLUSION: Micro-costing based on healthcare payer's data provides a relatively conservative albeit highly accurate estimate of costs in RA. Both RA related and non-RA related costs must be taken into account. In gainfully employed patients and in patients who receive RA related retirement payments productivity costs exceed direct costs.

INTRODUCTION: Complications of portal hypertension can be treated effectively by the transjugular intrahepatic portosystemic shunt procedure (TIPS). Indicators for long time survival after TIPS implantation are presented. PATIENTS AND METHODS: From September 1992 until May 1995 forty-two consecutive patients (26 male, 16 female) with liver cirrhosis complicated by variceal bleeding (n = 27) or refractory ascites (n = 15) were treated by TIPS implantation and followed up clinically in a prospective, open study. The follow up period range was 5-3278 days. Univariate and multivariate regression analyses were applied to determine the correlation between patient characteristics and long term survival after TIPS implantation. The indicators were dichotomized at the median. The outcome variable was dichotomized. Positive outcome was defined as survival longer than three years without liver transplantation, all other outcomes were regarded as negative. Survival rates were determined for all patients and for subgroups according to results of the regression analyses. RESULTS: During follow-up liver transplantation was performed in 8 of the 42 patients. 29 patients died. Mean survival was 1440 (+/-1060) days. Survival after one, two, three and six years was 76% (n = 32), 69%(n = 29), 62% (n = 26) and 38% (n = 16), respectively. The multivariate regression analysis revealed a significant better survival related to a prothrombine time >70%, MEGX synthesis >30 microgram/l, and ICG clearance <13 min. Patients with high ICG clearance (OR = 1.9), high MEGX synthesis (OR = 5.0) or high prothrombine time scores (OR = 5.2) had a significantly longer survival. This survival advantage increased with follow up time. CONCLUSION: Longterm survival after TIPS implantation is influenced by the initial liver function. This survival advantage increases during follow up and is most pronounced after 6 years.

PURPOSE: Evaluation of clinical relevance of the arterial stimulation procedure with venous sampling (ASVS) in the preoperative localization of insulinoma. METHODS: Thirteen patients with endogenous hyperinsulinism underwent preoperative transabdominal ultrasound (US), helical CT (CT), MRI, endoscopic ultrasound (EUS), and angiography (DSA) in conjunction with the ASVS-test for the detection of insulinoma. The results were compared with intraoperative findings, intraoperative ultrasound (IOUS) and histology. RESULTS: Sensitivity was as follows: US 8%, MRI 27%, CT 46%, EUS 50%,DSA 69%,and ASVS 92%. Intraoperative palpation and IOUS yielded a sensitivity of 77%. In 3 patients the tumors were neither palpable nor detectable by IOUS, the mode of resection was based on preoperative diagnostics. The ASVS procedure as a functional test was superior to all other modalities for the preoperative tumor detection. CONCLUSION: The ASVS was the most sensitive diagnostic modality. It should especially be considered in terms of health economical aspects when CT or MRI do not yield conclusive results.
