Dermatomyositis associated with malignant melanoma--a marker of poor prognosis?

BACKGROUND: Dermatomyositis (DM) is an inflammatory connective tissue disorder well recognized as a paraneoplastic syndrome in adults. OBJECTIVE: The objective of this study was to assess the prognosis of DM associated with malignant melanoma (MM). PATIENTS AND METHODS: We systematically searched databases (PubMed, MEDLINE, and WEB OF SCIENCE) for articles reporting the concurrence of DM and MM. For the literature study, time of onset of DM in relation to diagnosis of MM (before, concomitant with, or after), stage of MM after restaging (according to the American Joint Committee on Cancer [AJCC] guidelines, 2001), and survival time after diagnosis of DM were recorded. Survival time studies and univariate statistical analyses were performed. Furthermore, we present our own clinical case of a patient with DM concomitantly occurring with regional lymph node metastasis of MM. RESULTS: In 5 cases DM occurred before, in 6 cases concomitantly with, and in 6 cases after progression of MM. Univariate analysis identified the AJCC stage of MM as a significant prognostic factor. Gender, age, and the time interval between onset of DM and progression of melanoma were unrelated. The 1-year actuarial survival rate was 0% for patients with DM when occurring with MM at stage IV and 60% when occurring with MM at stage III (P < .05). The estimated mean survival time was 6.6 months for patients with MM stage IV and 57 months for stage III. LIMITATIONS: The conclusions from this study are limited by the relatively small number of articles that reported the association of MM and DM. CONCLUSION: DM occurring in patients with MM at stage IV is connected with an extremely poor prognosis, whereas the few reported patients with DM and MM at stage III, including our case, have a prognosis similar to stage III patients without DM.

[Current situation of dermatologic surgery in Germany].

BACKGROUND: Dermatologic surgery has become an increasingly important issue in dermatology in recent years. At present, no current epidemiologic or care-related data on cutaneous surgery procedures in dermatology are available. METHODS: To determine the extent of cutaneous surgery procedures in dermatological hospitals, a national survey was performed. Both the procedure codes for 2004 based on the OPS-classification and the DRG figures grouped to the major diagnostic category 09 of G-DRG version 2004 were considered in detail. Methods of descriptive statistics were applied. RESULTS: The submitted data reveal that the contributing hospitals provided 164487 cutaneous surgery procedures in the investigation period. The vast majority is represented by extensive procedures and plastic-reconstructive operations, as opposed to less complex surgeries such as simple excisions. Analysis of DRG assignment indicates that surgical procedures account for 44.2% of inpatient cases. CONCLUSIONS: The present survey demonstrates that in Germany cutaneous surgery procedures are widely performed by dermatological hospitals and dermatologists. The increasing incidence of melanoma and nonmelanoma skin cancer including precursor lesions will increase the need for dermatologists to perform cutaneous surgery in the future.

[G-dRG version 2005: relevant aspects for dermatology].

One year after the obligatory implementation of a new hospital funding system based on Diagnosis Related Groups (DRG) the third version of a German DRG-system has been published. It differs significantly from the previous version. Modifications in the classification system and the introduction of further procedure-based payments contribute to a better depiction of specialized clinical services. A number of acknowledged problems which caused great discussion in 2004 have been solved, yielding a more appropriate mapping of clinical services. The algorithms of the major diagnostic categories have been modified and complications, comorbidities and/or multiple procedures will be considered more precisely in selecting a group. However, some inconsistencies concerning highly specialized medical procedures and special features of impatient dermatological care remain. Nevertheless, a great improvement over the previous versions is apparent. The crucial aspects of the G-DRG version 2005 and the accompanying rules and regulations of payment are reviewed in detail with special relevance to dermatology.

Pathway management in ambulatory wound care: defining local standards for quality improvement and interprofessional care.

Growing health care costs and changes in health care delivery, such as the adoption of the diagnosis-related groups, have tremendously affected treatment patterns all over the world. Pathway management is suitable to be responsive to the growing operating requirements and to manage effective and efficient medical care in hospitals. Pathways standardise clinical processes for patients with a similar diagnosis, procedure or symptom thereby optimising the quality of treatment and patient satisfaction. They are utilised by a multidisciplinary team with a primary focus on quality and coordination of care. Considering the key strategies of pathway management, an interprofessional team containing physicians and nurses developed and implemented a clinical pathway for ambulatory treatment of chronic wounds. A precise medical protocol was created to standardise routine procedures, to improve the treatment outcome and to provide an integrated documentation that enhances interprofessional collaboration. We designed a modular concept of four different sheets which provide pre-defined standards: (a) medical admission, (b) findings and history, (c) topic and systemic treatment and (d) evaluation of outcome criteria. Variances must be merely written down in detail. After 1 year in clinical practice, we state that the use of a clinical pathway for chronic wound management is an effective method of improving clinical processes and patient outcomes.

[Introduction of quality management with the EFQM Self-Assessment method. Implementation and experience in a university department of dermatology].

In the near future, the German legislative and health insurance agencies will increasingly demand proof of quality in hospital health care. The role of quality management in hospitals is emphasized by the introduction of per-case payment (DRG) in Germany. The implementation of internal quality management at an early stage sets the course of a systematic and continuous quality improvement process, with the goal to increase performance and results by efficient utilization of resources. The decision for or against one or another quality management model appears to be difficult, since the possible impacts of the quality management system can hardly be foreseen. As this article shows, the Self-Assessment method of the European Foundation for Quality Management (EFQM) provides a valuable and efficient tool to introduce quality management in a hospital environment. The Self-Assessment method enables a systematic survey of levels of performance and outcome of the hospital. Furthermore, it provides an appropriate basis to identify areas of strengths and weaknesses. A high degree of motivation of the personnel is fostered by the creation of a local guidance circle, a coordinating group, and several Self-Assessment teams. However, formulation and deployment of improvement actions are necessary for the long-term implementation of quality management. The application of Self-Assessment in quality management appears a suitable tool to promote excellence.

[DRGs in dermatology: results of the DRG evaluation project of the German Society of Dermatology (DDG)].

SUMMARY BACKGROUND: The implementation of a DRG system in Germany--voluntarily since January 1st, 2003, and obligatory after January 1 st, 2004--has led to uncertainty, particularly in the hospitals. There are fears that current well-accepted German diagnostic and therapeutic services may not be properly financed by the new system. In response, the German Dermatologic Society (DDG) in cooperation with the DRG Research Group of the University Hospital Muenster and the German Medical Association carried out a DRG evaluation project in order to investigate the medical and economic homogeneity of the case groups. PATIENTS AND METHODS: 19,403 dermatological cases from 19 hospitals--ten university hospitals and nine non-university hospitals-were collected over a period of four months and then evaluated with regard to their performance, length of stay and cost homogeneity. RESULTS: The data provided the background needed to indicate suspected potential deficiencies for mapping dermatology cases within the German DRG system. Based on the data 10 modifications were formulated and submitted to the InEK by the deadline of March 31st, 2003. CONCLUSIONS: The results of the DRG Evaluation Project show that the G-DRG-Variant Version 1.0 does not offer the necessary possibilities of differentiation to map the broad spectrum of various dermatology services in Germany.

[G-DRG Version 2004: changes in view of dermatology].

In the year 2004 the obligatory introduction of the new hospital funding system based on a Diagnosis Related Groups (DRG) system will become reality for all German hospitals. After all fundamental items of the new G-DRG version were made generally known, the possible consequences had to be considered. The first mandatory German case-based lump sum catalogue differs importantly from the previous payment models and requires intensive study. Economic considerations will increasingly play a role in the daily routine of hospitals and influence treatment patterns. Therefore, comprehensive knowledge of basic principles of G-DRG is essential. In the following aspects of the reimbursement system with special relevance to dermatology are reviewed in detail. Additionally, the revised classification system versions OPS-301 SGB V and ICD-10-GM 2004 and the German coding standards version 2004 must be appropriately applied for dermatologic purposes.

[Patients' view of melanoma follow-up].

BACKGROUND: About 20% of melanoma patients develop progressive disease during follow-up. This is an alarming number for the patients. In view of new recommendations for melanoma follow-up, this study assesses the performance and quality of follow-up as perceived by the patients. PATIENTS AND METHODS: A questionnaire was distributed to 462 patients with melanoma being followed in the skin cancer units of the universities of Cologne and Münster. Follow-up was based on recommendations published in 1994 by Malignant Melanoma Committee of the German Dermatological Society. RESULTS: Follow-up was regularly performed. In Münster, 62% patients were seen in the university clinic, while in Cologne 53% of patients were followed jointly by the university clinic and practicing dermatologists. Radiological examinations were regularly repeated in 70% of the collective. 70% of patients reported performing self-examinations. 14% had developed progressive disease. 15% made use of psycho-social help. CONCLUSIONS: The questionnaire reveals that the interdisciplinary follow-up and self-examinations proposed in the new recommendations are already well accepted. Based on latest standards, 90% of the patients felt that follow-up was reassuring. Psychosocial services should be offered more directly with emphasis on both social services and psychological support. Systematic patient inquiries can be used to establish quality standards for follow-up which are more patient-oriented.

[Analysing strengths and weaknesses: opportunities and threats for service providers in the German health care system].

Hospitals in the German health care system are confronted with increasing economic competition due to paradigm shifts in funding inpatient treatment. Major hospitals, such as university hospitals, will be under significantly greater pressure to keep up the ability to compete by uniform per case payment. The new hospital funding system based on a Diagnosis Related Group (DRG) system and the economic competition involved require analyses of organisational and locational factors. Cooperativeness and efficient utilisation of resources, properties and staff will be determining factors to secure existence. Adequate responses and strategies are essential to cope with the growing operating requirements. Carrying out an analysis identifying one's own strengths and weaknesses, opportunities and threats will help to focus activities and sustainable strategies into areas where the strengths and the greatest opportunities lie. An example of the process of strategic planning and positioning is shown for a university department of dermatology.

[DRGs in dermatology: quality of coding and the effects of case mix].

BACKGROUND: High-quality coding of patient clinical data is mandatory for an effective DRG classification to result in adequate allocation of funding for inpatient treatment. The aim of the study was to determine the effect of controlled documentation on patient clinical data and to ascertain the outcome of calculated DRG-based yields depending on higher coding quality of patient treatment. PATIENTS AND METHODS: In a prospective study, 1914 patient clinical records from the Department of Dermatology, University of Muenster, were captured using different documentation standards and the data was analysed. Grouping was performed on the basis of the Australian Refined DRG system v4.1. Dermatological patients were broken down into eleven groups based on principle diagnosis. RESULTS: As a result of a controlled documentation, case mix, case mix index and patient clinical complexity level (PCCL) value were increased within identical samples. Furthermore, it was shown that high-quality coding may result in exact and reasonable classification of patient clinical data. CONCLUSIONS: Different documentation standards may cause undesired effects on the monetary yields of in-patient treatment. It appears that high-quality coding and controlled documentation may guarantee adequate yields. FauIty. incomplete and (up)coding could be a potential economic risk for hospitals.
