Eine Skala zur Messung von Beschwerden bei degenerativen Veränderungen der Halswirbelsäule (HWS) Hilfe zur Indikationsstellung und zur Evaluation des Operationserfolgs

A scale for measuring symptoms related to degenerative diseases of the cervical spine is presented. Twenty typical symptoms are listed, e. g., neck pain, dysesthesia, and reduced mobility. Responses are assessed via a 6-point scaling ("did not have symptom" - "had symptom and suffered very strongly".) The cervical spine scale was tested in three samples: patients having undergone cervical spine surgery (n = 70), patients with other orthopedic diagnoses (n = 104), and healthy students (n = 100). The single items of the scale were aggregated into four scores: total number of symptoms, degree of overall symptom distress, functional disability, and pain/psychological distress. Statistical analyses proved the high reliability (Cronbach's alpha = 0.85 to 0.95) and validity (content, convergent, discriminant) of all scores. The scale differs clearly between cervical spine patients, other orthopedic patients and healthy individuals, and between cervical spine patients with different subjective operative outcomes. For applied clinical purposes the cervical spine scale can be included in a quality of life profile (QL-profile); this allows for a readily understandable graphic depiction of individual patients' QL-status.     

Evaluation eines standardisierten Trainings für die “Positive and Negative Syndrome Scale” (PANSS)

The present analysis comprises 3 studies on the interrater reliability of the Positive and Negative Syndrome Scale for Schizophrenia (PANSS; German version). To our knowledge this is the first empirical report on interrater reliability and on results of rater training of the German version of the PANSS despite the widespread use of the scale. In a total of 47 training participants with different clinical experience standardized PANSS rater training was carried out and subsequently evaluated. Therefore, concordance rates with an expert standard (C) and weighted coefficients kappa (kappa W) were calculated. As a main outcome of the studies, at least 3 training sessions were necessary but also sufficient to reach acceptable interrater reliability of the PANSS (C > 80%, kw > 0.60). In training participants with low psychiatric experience the level of interrater reliability of schizophrenic negative symptoms did not reach the results of positive symptoms after the training. Despite some conceptual limitations with respect to negative symptoms, the German version of the PANSS seems highly suitable to assess a broad spectrum of schizophrenic psychopathology in a reliable and economic manner. The present results also underline the practicability of our recommendations for conducting PANSS rater training in the clinical and scientific field as part of quality control and quality assurance in psychopathological assessment.     

Qualitätsmanagement im interdisziplinären Fachkrankenhaus

The aim of quality management in rheumatology is to improve care and outcome in patients with rheumatic diseases. This can be achieved by means of prospective long-term observation of the patient with regular documentation of clinical, radiological, biochemical and functional data using certain validated scoring methods (DAS, radiological score, ADL score Hanover or Health assessment questionnaire, SF36, etc.). Long-term observation and documentation including radiographs have been performed in the rheumatology hospital in Ratingen for 20 years without even knowing the term quality management. Quality management in a hospital for rheumatic diseases begins with certain structural prerequisites: possibility of direct admission of a patient to the hospital by the family physician, outpatient clinic to investigate and to follow patients over a long period of time, multidisciplinary team with specialists in rheumatology, orthopedic surgery, physiotherapy, ergotherapy, special care, psychological, and social services, close cooperation with specialists in neurology, dermatology, ophthalmology, etc., department of radiology, special laboratory, facilities for internal diagnostic and treatment. The hospital needs a training program for the qualification of rheumatologists and orthopaedic surgeons. The hospital staff should closely cooperate with the doctors in private practice who admit patients and should continuously support patient organizations. The quality of outcome is influenced by the process quality which depends on the following factors: selection, training and motivation of the hospital staff; supervision of clinical assessment and documentation by senior physicians, daily x-ray demonstrations and case reports, interdisciplinary case demonstrations at least every week in addition to daily consultation, team reports, regular education including review of actual literature for physicians, education programs exchanging knowledge with physiotherapists and nurses, and regular education programs for patients. Process quality can only be achieved by an interdisciplinary approach and regular communication between all participants including the patient, whose opinion must be noted and regarded. As far as possible, the same doctor who treats the patient in the hospital should follow her/him in the outpatient clinic. The quality of outcome can be improved by regular reinvestigation of the patient with control of medication, side effects, efficacy, documentation of clinical, biochemical, radiological, and functional data. Decisions for further treatment have to be based on these follow-up data. A standardized follow up and documentation system for all rheumatology units with prompt feedback could definitely improve the quality of rheumatologic care in Germany.

Pharmakoökonomie und Public Health

The main purpose of Public health is improvement of the health state of the population. Thereby necessary coasts have to be considered. Public Health research is directly practice-related because of the development and implementation of health policy strategies. Important aims of the public health research are the realization of interventions in practice and their reevaluation. Health economy is an essential point of Public health. The public health research aims at analyzing the medical care and control systems. Further aims of the health economy are the individual processes of decisions of participating persons (e.g. physicians, patients)are object of research. Pharmacoeconomic aspects belong to an optimal therapy, that means the quality assurance and improvement with regard to circumstances. Quality assurance is not possible without the consideration of the state of knowledge. Only on the basis of actual data from the medical care system specific interventions on the political and individual level may be established. Subsequently these programs can be evaluated according to quality and cost outcomes. Drug information services and pharmacotherapy circles (Peer review groups)can contribute to an optimization in medical treatment. As a result these interventions are of consequence for health economy and medical care.     

Quality management in a radiology department

Purpose. To increase the quality of internal and external interactions (patients, clinical colleagues, technicians, radiologists) in a department of radiology. Method. Accompanied by a well-experienced adviser workshops have been performed dealing with different topics like “contact to patients”, “performance of the radiological report and interaction with the referring colleague” or “research and teaching”. A catalogue of different actions was defined to reduce hindrances within the internal and external work-flow. Results. A total number of 53 actions was defined and related to different persons who were responsible for the realisation of the measures within a time interval. Six months after starting the quality management 46 (86%) of the defined actions were realised successfully, and another 4 (8%) measures were still running. There was a moderate increase of satisfaction of the patients and clinical colleagues considering the waiting time. Conclusions. A quality management in a radiological department allows an optimisation of the internal and external interactions. However, the guidance of a well-experienced adviser is as essential as the continuous control of successful finished measures.
