Interaction of mental comorbidity and physical multimorbidity predicts length-of-stay in medical inpatients.

BACKGROUND: Mental comorbidities of physically ill patients lead to higher morbidity, mortality, health-care utilization and costs. OBJECTIVE: The aim of the study was to investigate the impact of mental comorbidity and physical multimorbidity on the length-of-stay in medical inpatients at a maximum-care university hospital. DESIGN: The study follows a retrospective, quantitative cross-sectional analysis approach to investigate mental comorbidity and physical multimorbidity in internal medicine patients. PATIENTS: The study comprised a total of n = 28.553 inpatients treated in 2017, 2018 and 2019 at a German Medical University Hospital. MAIN MEASURES: Inpatients with a mental comorbidity showed a median length-of-stay of eight days that was two days longer compared to inpatients without a mental comorbidity. Neurotic and somatoform disorders (ICD-10 F4), behavioral syndromes (F5) and organic disorders (F0) were leading with respect to length-of-stay, followed by affective disorders (F3), schizophrenia and delusional disorders (F2), and substance use (F1), all above the sample mean length-of-stay. The impact of mental comorbidity on length-of-stay was greatest for middle-aged patients. Mental comorbidity and Elixhauser score as a measure for physical multimorbidity showed a significant interaction effect indicating that the impact of mental comorbidity on length-of-stay was greater in patients with higher Elixhauser scores. CONCLUSIONS: The findings provide new insights in medical inpatients how mental comorbidity and physical multimorbidity interact with respect to length-of-stay. Mental comorbidity had a large effect on length-of-stay, especially in patients with high levels of physical multimorbidity. Thus, there is an urgent need for new service models to especially care for multimorbid inpatients with mental comorbidity.

[Treatment clusters and personnel assessment in psychosomatic medicine and psychotherapy - results of a feasibility study of the platform model]. / Behandlungscluster und Personalbemessung in der psychosomatischen Medizin und Psychotherapie ­ Ergebnisse einer Machbarkeitsstudie zum Plattformmodell.

Treatment clusters and personnel assessment in psychosomatic medicine and psychotherapy - results of a feasibility study of the platform model Objectives: In accordance with the legal requirements of the PsychVVG, it is necessary to develop criteria for inpatient and day-care psychosomatic psychotherapeutic care, which can be used to determine the appropriate staffing for different treatment areas and different care structures. For psychosomatic medicine and psychotherapy a model with four treatment clusters was developed, which is oriented on the one hand to the psychotherapeutic intensity and on the other hand to the medical expenditure. Method: In three consecutive rounds with up to 30 experts, representative selected from the three institution types university hospital, departmental psychosomatic medicine and specialized clinic, the minute values per patient required for a treatment according to the guidelines were determined using the Delphi method. Newly developed activity profiles for the six occupational groups were used, which allow the recording of all patient- and setting-related activities. Results: With the results of the feasibility study, an instrument has been developed for the first time to determine the requirements of staffing in psychosomatic medicine. Convergent minute values could be formulated for three of the four treatment clusters. Conclusions: The provision of care in psychosomatic medicine and psychotherapy is complex, so that a limitation to four treatment areas is only possible if significantly more generous equivalence rules are applied between the professional groups than those laid down in the PPP Directive.

[Staffing level: Survey among psychosomatic-psychotherapeutic institutions in Germany]. / Personalausstattung: Befragung psychosomatischpsychotherapeutischer Kliniken und Abteilungen in Deutschland.

Staffing level: Survey among psychosomatic-psychotherapeutic institutions in Germany Objectives: To establish the first nationwide hospital survey to assess the level of staffing for inpatient and daycare treatment in psychosomatic hospitals and specialist departments in Germany. METHODS: Using a standardized written hospital survey from the Deutsches Krankenhausinstitut (DKI), we invited a total of 218 psychosomatic-psychotherapeutic hospitals and specialist departments to participate. The participation rate of the institutions was 35%. RESULTS: In the overall sample, one psychotherapist (physician/clinical psychologist) was responsible for treating a median of 3.9 beds/patients (interquartile range 3.1-5.1) and one nurse a median of 2.9 beds/patients (interquartile range 2.3-3.9). There were significant differences for the nurse-patient ratio depending on the organizational size of the institution. To ensure quality treatment, professional experts saw increased staffing needs of about 12-17% across both professions. For the professional groups of specialist therapists and social workers, broad variances were observed for the therapist-patient ratio in the overall sample. CONCLUSIONS: The study provides an important and relevant data basis for the further discussion to determine mandatory minimal staffing levels in German psychosomatic-psychotherapeutic institutions.

Evidence for Distinguishable Treatment Costs among Paranoid Schizophrenia and Schizoaffective Disorder.

BACKGROUND: Schizophrenia spectrum disorders result in enormous individual suffering and financial burden on patients and on society. In Germany, there are about 1,000,000 individuals suffering from schizophrenia (SZ) or schizoaffective disorder (SAD), a combination of psychotic and affective symptoms. Given the heterogeneous nature of these syndromes, one may assume that there is a difference in treatment costs among patients with paranoid SZ and SAD. However, the current the national system of cost accounting in psychiatry and psychosomatics in Germany assesses all schizophrenia spectrum disorders within one category. METHODS: The study comprised a retrospective audit of data from 118 patients diagnosed with paranoid SZ (F20.0) and 71 patients with SAD (F25). We used the mean total costs as well as partial cost, i.e., mean costs for medication products, mean personal costs and mean infrastructure costs from each patient for the statistical analysis. We tested for differences in the four variables between SZ and SAD patients using ANCOVA and confirmed the results with bootstrapping. RESULTS: SAD patients had a longer duration of stay than patients with SZ (p = .02). Mean total costs were significantly higher for SAD patients (p = .023). Further, we found a significant difference in mean personnel costs (p = .02) between patients with SZ and SAD. However, we found no significant differences in mean pharmaceutical costs (p = .12) but a marginal difference of mean infrastructure costs (p = .05) between SZ and SAD. We found neither a common decrease of costs over time nor a differential decrease in SZ and SAD. CONCLUSION: We found evidence for a difference of case related costs of inpatient treatments for paranoid SZ and SAD. The differences in mean total costs seem to be primarily related to the mean personnel costs in patients with paranoid SZ and SAD rather than mean pharmaceutical costs, possibly due to higher personnel effort and infrastructure.

[Normative-empirical determination of personnel requirements in psychosomatic medicine and psychotherapy]. / Normativ-empirische Bestimmung des Personalbedarfs in der Psychosomatischen Medizin und Psychotherapie.

OBJECTIVES: There is a high degree of misallocated medical care for patients with somatoform disorders and patients with concomitant mental diseases. This complex of problems could be reduced remarkably by integrating psychosomatic departments into hospitals with maximum medical care. Admitting a few big psychosomatic specialist clinics into the calculation basis decreased the Day-Mix Index (DMI). The massive reduction of the calculated costs per day leads to a gap in funding resulting in a loss of the necessary personnel requirements - at least in university psychosomatic departments. The objective of this article is therefore to empirically verify the reference numbers of personnel resources calculated on the basis of the new German lump-sum reimbursement system in psychiatry and psychosomatics (PEPP). METHODS: The minute values of the reference numbers of Heuft (1999) are contrasted with the minute values of the PEPP reimbursement system in the years 2013 and 2014, as calculated by the Institute for Payment Systems in Hospitals (InEK). RESULTS: The minute values derived from the PEPP data show a remarkable convergence with the minute values of Heuft's reference numbers (1999). CONCLUSIONS: A pure pricing system like the PEPP reimbursement system as designed so far threatens empirically verifiable and qualified personnel requirements of psychosomatic departments. In order to ensure the necessary therapy dosage and display it in minute values according to the valid OPS procedure codes, the minimum limit of the reference numbers is mandatory to maintain the substance of psychosomatic care. Based on the present calculation, a base rate of at least 285 e has to be politically demanded. Future developments in personnel costs have to be refinanced at 100 %.

Electronic acquisition of OSCE performance using tablets.

BACKGROUND: Objective Structured Clinical Examinations (OSCEs) often involve a considerable amount of resources in terms of materials and organization since the scores are often recorded on paper. Computer-assisted administration is an alternative with which the need for material resources can be reduced. In particular, the use of tablets seems sensible because these are easy to transport and flexible to use. AIM: User acceptance concerning the use of tablets during OSCEs has not yet been extensively investigated. The aim of this study was to evaluate tablet-based OSCEs from the perspective of the user (examiner) and the student examinee. METHOD: For two OSCEs in Internal Medicine at the University of Heidelberg, user acceptance was analyzed regarding tablet-based administration (satisfaction with functionality) and the subjective amount of effort as perceived by the examiners. Standardized questionnaires and semi-standardized interviews were conducted (complete survey of all participating examiners). In addition, for one OSCE, the subjective evaluation of this mode of assessment was gathered from a random sample of participating students in semi-standardized interviews. RESULTS: Overall, the examiners were very satisfied with using tablets during the assessment. The subjective amount of effort to use the tablet was found on average to be "hardly difficult". The examiners identified the advantages of this mode of administration as being in particular the ease of use and low rate of error. During the interviews of the examinees, acceptance for the use of tablets during the assessment was also detected. DISCUSSION: Overall, it was found that the use of tablets during OSCEs was well accepted by both examiners and examinees. We expect that this mode of assessment also offers advantages regarding assessment documentation, use of resources, and rate of error in comparison with paper-based assessments; all of these aspects should be followed up on in further studies.

Assessing the prognoses on Health care in the information society 2013--thirteen years after.

Health care and information technology in health care is advancing at tremendous speed. We analysed whether the prognoses by Haux et al. - first presented in 2000 and published in 2002 - have been fulfilled in 2013 and which might be the reasons for match or mismatch. Twenty international experts in biomedical and health informatics met in May 2013 in a workshop to discuss match or mismatch of each of the 71 prognoses. After this meeting a web-based survey among workshop participants took place. Thirty-three prognoses were assessed matching; they reflect e.g. that there is good progress in storing patient data electronically in health care institutions. Twenty-three prognoses were assessed mismatching; they reflect e.g. that telemedicine and home monitoring as well as electronic exchange of patient data between institutions is not established as widespread as expected. Fifteen prognoses were assessed neither matching nor mismatching. ICT tools have considerably influenced health care in the last decade, but in many cases not as far as it was expected by Haux et al. in 2002. In most cases this is not a matter of the availability of technical solutions but of organizational and ethical issues. We need innovative and modern information system architectures which support multiple use of data for patient care as well as for research and reporting and which are able to integrate data from home monitoring into a patient centered health record. Since innovative technology is available the efficient and wide-spread use in health care has to be enabled by systematic information management.

Past and next 10 years of medical informatics.

More than 10 years ago Haux et al. tried to answer the question how health care provision will look like in the year 2013. A follow-up workshop was held in Braunschweig, Germany, for 2 days in May, 2013, with 20 invited international experts in biomedical and health informatics. Among other things it had the objectives to discuss the suggested goals and measures of 2002 and how priorities on MI research in this context should be set from the viewpoint of today. The goals from 2002 are now as up-to-date as they were then. The experts stated that the three goals: "patient-centred recording and use of medical data for cooperative care"; "process-integrated decision support through current medical knowledge" and "comprehensive use of patient data for research and health care reporting" have not been reached yet and are still relevant. A new goal for ICT in health care should be the support of patient centred personalized (individual) medicine. MI as an academic discipline carries out research concerning tools that support health care professionals in their work. This research should be carried out without the pressure that it should lead to systems that are immediately and directly accepted in practice.

Good exams made easy: the item management system for multiple examination formats.

BACKGROUND: The development, implementation and evaluation of assessments require considerable resources and often cannot be carried out by a single faculty/institution. Therefore some medical faculties have founded cooperation projects which mainly focus on the exchange of multiple choice questions (MCQs). METHODS: Since these cooperation projects do not entirely support all relevant processes in terms of preparation, implementation and evaluation of assessment, in 2006 the Medical Assessment Alliance (MAA) was founded for mutual support. In addition to MCQs the MAA started to develop innovative assessment formats and facilitate content through a coordinated exchange of experiences. To support cooperation within this network, the web-based Item Management System (IMS) was developed which supports all processes of the assessment workflow as an all-in-one working platform. RESULTS: At present, the Alliance has 28 partner faculties in Europe. More than 2.800 users in 750 working groups are collaborating. Currently 90.000 questions have been stored in the IMS. Since 2007, nearly 4.600 examinations have been successfully conducted. CONCLUSION: This article describes in detail the unique features of the IMS and contrasts it with the item management systems of other associations.

Does medical students' preference of test format (computer-based vs. paper-based) have an influence on performance?

BACKGROUND: Computer-based examinations (CBE) ensure higher efficiency with respect to producibility and assessment compared to paper-based examinations (PBE). However, students often have objections against CBE and are afraid of getting poorer results in a CBE.The aims of this study were (1) to assess the readiness and the objections of students to a CBE vs. PBE (2) to examine the acceptance and satisfaction with the CBE on a voluntary basis, and (3) to compare the results of the examinations, which were conducted in different formats. METHODS: Fifth year medical students were introduced to an examination-player and were free to choose their format for the test. The reason behind the choice of the format as well as the satisfaction with the choice was evaluated after the test with a questionnaire. Additionally, the expected and achieved examination results were measured. RESULTS: Out of 98 students, 36 voluntarily chose a CBE (37%), 62 students chose a PBE (63%). Both groups did not differ concerning sex, computer-experience, their achieved examination results of the test, and their satisfaction with the chosen format. Reasons for the students' objections against CBE include the possibility for outlines or written notices, a better overview, additional noise from the keyboard or missing habits normally present in a paper based exam. The students with the CBE tended to judge their examination to be more clear and understandable. Moreover, they saw their results to be independent of the format. CONCLUSIONS: Voluntary computer-based examinations lead to equal test scores compared to a paper-based format.

Psychiatric comorbidity in cardiovascular inpatients: costs, net gain, and length of hospitalization.

OBJECTIVE: Although psychiatric comorbidity often goes undetected and untreated in cardiovascular patients, it is not clear whether the costs for a special treatment of psychiatric comorbidity are appropriately reflected in the reimbursement system. To investigate the economic impact of psychiatric comorbidity, we compared costs, returns, net gain, and duration of hospitalization in cardiovascular inpatients with and without psychiatric comorbidity. METHODS: For a period of 2 years, we analyzed costs, net gain, and other outcome variables according to the diagnosis-related group (DRG) system for cardiovascular inpatients of a German university department (n = 940). Psychiatric disorders were diagnosed by the treating physicians based on clinical criteria and results from the Patient Health Questionnaire (PHQ). With respect to the outcome variables, we compared patients with and without a psychiatric disorder, controlling for sociodemographic characteristics. RESULTS: The average total costs of hospitalization (mean ± S.E.) for cardiovascular patients without psychiatric comorbidity and for patients with psychiatric comorbidity differed significantly (€5142 ± 210 vs. €7663 ± 571; d = 0.39). The increased costs for patients with psychiatric comorbidity were related to elevated returns, but the net gain for patients without psychiatric comorbidity was €277 ± 119. In contrast, the treatment of internal medicine patients with psychiatric disorders resulted in a net loss of -€624 ± 324 (overall group difference, d = -0.25). CONCLUSION: Psychiatric comorbidity in cardiovascular inpatients leads to higher costs that are not reflected in the current reimbursement system in Germany. The inappropriate reimbursement of psychiatric comorbidity in cardiovascular inpatients may result in a serious undertreatment of these patients.

Risk of Confusion: Detection of a Circular Thickness of the Wall in the Lower Part of the Esophagus.

We report a case of a woman with a gastrointestinal bleeding. An esophageal ulcer was detected in the endoscopy, however a histological malignancy could not be found. A computer tomography (CT) scan showed a thickness in the distal esophagus and enlarged lymph nodes, so a malignancy was highly suspected. However, the patient refused to follow the recommended clinical procedure of a surgical intervention. Four years later a carcinoma could be ruled out because of follow-up examinations.

Spontaneous pneumomediastinum in anorexia nervosa: a case report and review of the literature on pneumomediastinum and pneumothorax.

We report a case of a 20-year-old white woman with the history of anorexia nervosa presenting with spontaneous pneumomediastinum (SPM). On admission, her body mass index (BMI) was 9.9 kg/m(2). Physical examination revealed subcutaneous crepitation especially in the axillae, the intercostal spaces, between the scapulae and along the spine. A chest X-ray showed extensive tissue emphysema, especially in the upper mediastinum. In a computed tomography (CT) scan, additional air was found in the upper retroperitoneal space adjacent to the stomach and to the left of the aorta. The patient recovered clinically within three weeks, and a CT scan showed a complete remission of the pneumomediastinum and subcutaneous emphysema. Based on this, case review of the literature about the frequency of pneumomediastinum in young patients with low weight is presented concerning epidemiology, etiology, symptoms, diagnosis, treatment, time to recovery and prognosis.

A shared decision-making communication training program for physicians treating fibromyalgia patients: effects of a randomized controlled trial.

OBJECTIVE: Fibromyalgia syndrome (FMS) is a condition of chronic widespread pain that is difficult to control and is associated with strains in physician-patient interaction. Shared decision making (SDM) can be a potential solution to improve interaction. We evaluated the effects of an SDM intervention, including an SDM communication training program for physicians, in a randomized controlled trial with FMS patients. The main objective was to assess whether SDM improves the quality of physician-patient interaction from patients' perspective. METHODS: Patients were randomized to either an SDM group or an information-only group. The SDM group was treated by physicians trained in SDM communication and had access to a computer-based information package; the information-only group received only the information package and was treated by standard physicians. All patients were offered the same evidence-based treatment options for FMS. Patients were assessed with questionnaires on physician-patient interaction (main outcome criteria) and decisional processes. Physicians filled out a questionnaire on interaction difficulties. Assessment took place immediately after the initial consultation. RESULTS: Data from 85 FMS patients (44 in the SDM group and 41 in the information-only group) were analyzed. The mean age was 49.9 years (S.D.=10.2), and 91.8% of patients were female. The quality of physician-patient interaction was significantly higher in the SDM group than in the information-only group (P<.001). We found no differences in secondary outcome measures. CONCLUSIONS: SDM with FMS patients might be a possible means to achieve a positive quality of physician-patient interaction. A specific SDM communication training program teaches physicians to perform SDM and reduces frustration in patients.

[Multilevel modelling applied to the analysis of diary data of obese patients with and without binge eating disorder]. / Anwendung der Mehrebenenmodellierung zur Auswertung von Tagebuchdaten adipöser Patienten mit und ohne Binge Eating Disorder.

Fitting multilevel models to diary data allows the analysis of development trends, group differences, and breakpoints in time trends. The aim of this study is the application of multilevel modelling to determine time trends in the diary data of a group of obese patients with and without binge eating disorder (BED). Throughout the course of a four-month multi-modal intervention program, the patients answered questions daily on handheld computers about their eating behaviour as well as their psychological and physical states. Multilevel analysis of the diary data shows that initially the trend of the eating behaviour over time decreases but increases towards the end of the therapy. Results of the application of a relatively new method to identify break points in linear trends indicate that the 85 (th) day of the therapy is a break point in the trend over time of the eating behaviour. Significant differences in the development of the eating behaviour over time were found for the subgroups of patients with and without BED.

[Elevated costs of treatment in medical inpatients with psychiatric comorbidity are not reflected in the German DRG-system]. / Höhere Kosten bei internistischen Krankenhauspatienten mit psychischer Komorbidität: Fehlende Abbildung im DRG-System.

OBJECTIVE: So far, it remains unclear whether treatment of psychiatric comorbidity in medical inpatients is appropriately reflected in the German Diagnosis-Related Groups (DRG) system. Therefore, we investigated the relationship of psychiatric disorders and costs, returns, net gain, and duration of hospitalization in internal medicine inpatients. METHODS: For a period of 1 year, we analyzed costs, net gain and other outcome variables according to the DRG system for all inpatients of a university department of internal and psychosomatic medicine (n = 697). Psychiatric disorders were diagnosed by the treating physicians based on clinical criteria and results from the Patient Health Questionnaire (PHQ). With respect to the outcome variables, we compared three groups of patients with none, one, and more than one psychiatric disorder controlling for sociodemographic characteristics. RESULTS: The average total costs of the hospitalization (M +/- SD) for internal medicine patients without psychiatric comorbidity (4357 +/- 5312 euro), for patients with one psychiatric disorder, (4733 +/- 5389 euro), and for patients with more than one psychiatric disorder (7163 +/- 8277 euro) differed significantly (p = 0.0003). However, the increased costs for patients with psychiatric comorbidity were not related to elevated returns: the net gain for patients without psychiatric comorbidity was 457 +/- 2884 euro; in contrast, the treatment of internal medicine patients with one and more than one psychiatric disorder resulted in a net loss of - 260 +/- 2389 euro and - 348 +/- 3370 euro, respectively (overall group difference, p = 0.03). CONCLUSIONS: Additional work and expenses caused by patients with psychiatric comorbidity should be documented and reflected in the revenue systems. Practical self-report screening questionnaires may help to detect and treat psychiatric disorders in internal medicine inpatients as early as possible.

Low intestinal glutamine level and low glutaminase activity in Crohn's disease: a rational for glutamine supplementation?

Intestinal glutamine utilization is integral to mucosal regeneration. We analyzed the systemic and intestinal glutamine status in Crohn's disease (CD) and evaluated the therapeutic effect of glutamine supplementation in an animal model of ileitis. In CD, glutamine concentrations were decreased systemically and in noninflamed and inflamed ileal/colonic mucosa. Mucosal glutaminase activities were depressed in the ileum independent of inflammation but were not different from controls in the colon. In experimental ileitis, oral glutamine feeding prevented macroscopic inflammation, enhanced ileal and colonic glutaminase activities above controls, and normalized the intestinal glutathione redox status. However, glutamine supplementation enhanced myeloperoxidase activity along the gastrointestinal tract and potentiated lipid peroxidation in the colon. In conclusion, glutamine metabolism is impaired in CD. In experimental ileitis, glutamine supplementation prevents inflammatory tissue damage. In the colon, however, which does not use glutamine as its principal energy source, immune enhancement of inflammatory cells by glutamine increases oxidative tissue injury.

A computer-based information-tool for chronic pain patients. Computerized information to support the process of shared decision-making.

OBJECTIVE: Assessment of the use of a computerized information-tool in the context of a shared decision-making process with chronic pain patients. METHODS: In the scope of a prospective and randomized study on shared decision-making with Fibromyalgia patients, a total of 75 patients had access to computer-based information about their illness. Fibromyalgia is a condition of chronic wide-spread pain, belonging to rheumatism, which mainly affects mature female patients. The majority of the patients in our study are female (93%) with an average age of 50 years. The computer-based information-tool provided the patients with detailed information about pathogenesis, typical symptoms, treatment options and prognosis. Six evaluative questions were posed to the participants concerning the assessment of the information presented, the handling of the programme, the need for an introduction to the programme, the quality of the layout and the assessment of the length of time spent in front of the computer and the assessment of the usefulness of such a tool in general practitioners' offices. Furthermore, psychological self-assessment questionnaires were filled out by the participants. RESULTS: The patients highly appreciate the possibility of using computer-based information-tools and endorse the implementation of such tools in general practitioners' offices. CONCLUSION: Computerized information leads to a better understanding of the illness and the treatment options on the part of the patient. PRACTICAL IMPLICATIONS: For further practical use it is crucial to provide an introduction to the handling of a computer to unskilled patients.

Improvement of the educational process by computer-based visualization of procedures: randomized controlled trial.

BACKGROUND: Before any invasive procedure, physicians have a legal obligation to inform patients. Traditionally, this involves a discussion with a physician, supplemented by written leaflet information directed at the specific procedure. OBJECTIVE: Comparison of the use and effectiveness of computer-based visualization opposed to standardized conversation for providing patients with information of forthcoming procedures (coronary catheters or endoscopy procedures). METHODS: Prospective, randomized trial with 56 participants allocated in two different groups: Visualization Group (standardized information supported by a tool for displaying two-dimensional pictures to explain medical facts as well as informative leaflet) or Control Group (standardized information and informative leaflet only). Detailed information was given about the indication, the probable complications and the details of the forthcoming procedures (coronary catheters or endoscopy procedures). All participants had to reach a Karnofsky Score of 70 points and be able to understand German or English. Main outcome measures were patient's satisfaction with physician-patient conversation, patient's acquired knowledge and duration of the intervention as described above. RESULTS: Patients of the Visualization Group were more satisfied with the conversation and had higher knowledge scores after the conversation. A Mann-Whitney-U-Test between the two groups showed that these differences in satisfaction (P<0.001) and knowledge (P= or <0.006) were statistically significant. Length of time needed for the conversation was slightly higher in the Visualization Group, but this difference was not statistically significant (25 versus 23 min; P= 0.441). No differences could be found due to differing age or educational level in the results of the Visualization and the Control Group. CONCLUSIONS: Using computerized visualization increased the satisfaction and knowledge of the patients. The presentation of the visualized information in the Visualization Group did not demand significantly more time than the standard conversation in the Control Group.

[The process of shared decision making in chronic pain patients. Evaluation and modification of treatment decisions]. / Der Prozess der partizipativen Entscheidungsfindung bei chronischen Schmerzpatienten. Evaluation und Modifikation von Therapieentscheidungen.

Conditions affecting the musculoskeletal system are the cause of approximately 25% of absenteeism from work. Fibromyalgia syndrome is an exemplary condition of chronic widespread pain which most physicians consider difficult to manage. The physician-patient relationship is burdened with resignation and frustration on both sides. Initial agreement regarding the aims of treatment is rare. The patient's active involvement in the decision making process is expected to improve the physician-patient relationship. One aspect of this shared decision making process is the evaluation and possibly modification of treatment decisions. In the present study 39 consultations of physicians who had undergone special communication training were examined as to whether these physicians actually exercised the option of revising their treatment decisions. In 87.2% of the consultations the therapy decisions were modified within three months after the first encounter. Patients considered to be "difficult" were less likely to modify their decisions. The shared decision making process usually takes more than one consultation.
