<h3>Hintergrund</h3>
 +
 
 +
Chronic wounds are challenging medical conditions imposing great burden to the patients, the society and the payersi. Medical complexity is caused by the large variation in pathogenetic conditions, clinical features and comorbiditiesii.
 +
Patients greatly experience marked reductions of quality of lifeiiiivvvivii, substantial cumulative life course impairmentviii and widely unmet needs from treatmentix. The socio-economic impact of chronic wounds is considerable. Annual average costs per patient are high, reaching 8,500 Euros for venous leg ulcersx and about 10,000 Euros for arterial ulcersxi in Germany. Driving factor of the overall costs is the great number of patients with chronic wounds in the society. Based on data from the statutory health insurances, the incidence of chronic wounds in Germany is about 0.1%, the prevalence 0.9%xii. Countrywide, about 900,000 patients with chronic wounds are actively treated. The quality of health care shows large variations. Good quality is predicted by involvement of wound specialists in the treatment processxiii. Finally, achievement of substantial health-related quality of life is a major goal in wound carexiv.
 +
 
 +
Accurate and efficient treatment includes the use of outcomes measures both in clinical care and in research. Health care can further be optimised by using treatment goals over time. Standardised sets of wound documentation and outcomes parameters facilitate wound care in clinical routine. Specific criteria for the interpretation of results and definitions of clinically meaningful outcomes are needed. To date, no such systematic standards have been published and consented in Germany like in most other countries. Instead, there still is a lack of consensus on the documentation and measurement of chronic wounds. Furthermore, no harmonisation on standardised goal setting in wound treatment has occurred.
 +
 
 +
In order to establish standards for wound outcomes measurement and interpretation, a German national consensus group was started in 2012. This group included representatives from the national medical scientific societies associated with chronic wound care. Moreover, members of regional wound networks, other decision-makers and experts from various professional and institutional fields were invited.
 +
The present paper presents the processes and structures of the national consensus group, the quality standards and the prioritised topics of work.
 +
 
 +
A first comprehensive analysis was conducted by a EWMA task force on wound outcomesxv.

Chronic wound evaluation</br>

Even the trials included in the metaanalysis by Palfreyman et al. xvi markedly lacked of information and scientific vigour for essentials like blinding, power calculation and comparability of baselines between the comparators. The same findings were reported by Heyer et al. xvii (Fig. 1). In this more extended metaanalysis, only less than 5% of publications had a satisfying design and reporting of outcomes measures.

<h4>Set-up of the national consensus group</h4>
 +
The consensus group was initiated by members of different wound healing societies involved in health services research for chronic wounds in Germany. Coordinated by the German centers for health services research and dermatology (CVderm) and in vascular diseases (CVvasc), the major medical societies involved in health care for wounds were identified and invited for collaboration. Moreover, the German sick fund organisations and the major German wound care networks as well as the German conference for nursing standards were approached. Overall, 28 different parties were invited for the first meeting. At this meeting, a charter and procedural standards for the group process were agreed. The delegates elected the chairpersons and the moderator of the meetings. They also decided on the frequency of meetings and the communication between the decision circles.
 +
 
 +
<h4>Formal decision process</h4>
 +
The consensus work is based on a structured decision process coordinated by a trained moderator. All processes are regulated in the charter approved by all delegates. The decision process was initiated with a group discussion in the first face-to-face meeting and formally continued by web-based Delphi rounds. The list of topics and the choice of indications was prepared by the steering group and extended to the working group in the next meeting. Voting was obtained independently from the face-to-face meetings. A final decision was achieved and finalised in the next face-to-face meeting.
 +
 
 +
<h4>Standards of the decision process</h4>
 +
The decision process was standardised in the following way (Fig. 2): first, a systematic literature search was conducted in order to identify any previous literature relevant to the topics. The state of the art from literature was presented to the group by selected group members and at first recommendation for the decisions was given.
 +
 
 +
 
 +
<h3>Results</h3>
 +
 
 +
<h4>Consensus on standard and minimum data set</h4>
 +
The group identified the definition of minimum and standard data sets as a key task of the consensus. After a systematic literature search and work-up of articles published in the international databases (Pubmed, Medline) the publications available on the data sets were reported to the group and discussed. The selection of the variables considered relevant for the minimum standard data set was then agreed in a web-based Delphi process.
 +
 
 +
<h4>Classification of items</h4>
 +
Beside of the minimum and standard item set, a consensus was reached on the definition, classification and thresholds of all items selected. This agreement was also based on repeated Delphi rounds.
 +
 
 +
 
 +
<h4>Selection of topics</h4>
 +
The list of topics and indications to be addressed in the standardisation process was consented based on a three steps Delphi consensus process. With respect to indications, leg ulcers had the highest priority, followed by diabetic foot ulcers and pressure ulcers (Fig. 2).

 +
In this area, items are to be consented which are valid and visible for the use in clinical research, including controlled trials and patient registries. Furthermore, relevant meaningful differences are needed.
 +
 
 +

 +
The set of parameters was consented for the use of specific questions on health care processes and outcomes related to wound care. In particular, a set of quality indicators related to guidelines is defined.
 +
 
 +

 +
Wound-related standards are consented for health economic analysis related to cost-of-illness as well as cost-effectiveness studies on a wide range of treatments and care.

 +
The use of German sick fund data and other sources providing secondary data is reflected and consented in this section.

<h4>Aktueller Stand</h4>
 +
In the meantime after seven face-to-face meetings and nine web-based Delphi votes, the whole package for leg ulcers has been consented.
 +
Currently, the consensus is reported to the boards of the national medical societies for approval. An implementation will start immediately after final approval.
 +
 
 +
 
 +
<h3>Diskussion</h3>
 +
The aim of the current project is a systematic development of standards for the documentation and outcomes measurement in chronic wounds. This consensus meets a gap between clinical practice, clinical research, health care research and health economics for wounds on the one hand and evidence-based outcomes research on the other. Standards and harmonisation will support a better comparability and efficiency in routine car for wounds. It will also raise the quality of research by permitting comparing studies and metaanalyses, which so far were challenged by the heterogeneity of outcomes parameters17. Like in other fields of wound care, the dissemination of such outcomes instruments and the use of specific implementation tools is crucialxix. The national conference has included this in the decision-making process.
 +
 
 +
<h4>Schlussfolgerungen</h4>
 +
Based on a national joint process involving the medical societies, the nursing groups, the German sick funds and health politics, a continuous decision process on standards for outcomes measurement and interpretation could be established. The decision processes based on delphi consensus rounds showed high levels of participations and thus provide a valid and robust set of standards. First results are in the process of approval by the societies. The implementation of the outcomes will then be crucial.

Zusammenfassung

Chronische Wunden sind eine medizinische Herausforderung und stellen eine große Belastung für die Patienten, die Gesellschaft und die Kostenträger dar. Zu einer genauen und effizienten Behandlung gehört der Einsatz von Ergebnismessungen sowohl in der klinischen Versorgung als auch in der Forschung. Bis heute mangelt es noch immer an einem Konsens über Standards für die Dokumentation und Messung chronischer Wunden, an Vereinbarungen über die Interpretation von Wundheilungsergebnissen und an einer Vereinheitlichung der standardisierten Zielsetzung in der Wundbehandlung.

Schlüsselwörter

Chronische Wunden, Ergebnismessung, Dokumentation, Validierung, Gesundheitsfürsorge, Forschung im Gesundheitswesen, Konsensuskonferenz

Ziel

1) Einrichtung einer nationalen deutschen Konsensgruppe zur Definition von Standards für die Ergebnismessung und Interpretation chronischer Wunden, 2) Vereinbarung von Empfehlungen für Praxis und Forschung auf der Grundlage eines kontinuierlichen Entscheidungsprozesses, einschließlich der Umsetzung der Standards.

Methoden

Initiiert von den deutschen Zentren für Versorgungsforschung in der Dermatologie (CVderm) und bei Gefäßerkrankungen (CVvasc) umfasst diese nationale Konsensgruppe Delegierte der nationalen Pflegeausschüsse und der deutschen medizinischen Fachgesellschaften, die sich mit der Versorgung chronischer Wunden befassen sowie der Vorsitzenden regionaler Wundnetzwerke. Darüber hinaus wurden die Dachverbände der deutschen Krankenkassen, das deutsche Gesundheitsministerium und weitere Einzelwundexperten eingeladen. Die Konsensarbeit basiert auf einem strukturierten Entscheidungsprozess, der von einem geschulten Moderator koordiniert wird. Alle Prozesse sind in einer von allen Delegierten genehmigten Charta geregelt.

Ergebnisse

Die Konsensgruppen bestehen aus 58 Vertretern und Ko-Vertretern von 26 Gesellschaften und Organisationen. Seit 2012 wird bei den regelmäßigen halbjährlichen Treffen ein Delphi-basierter Arbeitsablauf befolgt, beginnend mit Standards für die Dokumentation und Ergebnismessung bei Patienten mit Beinulzera. Darüber hinaus werden webbasierte Entscheidungsprozesse durchgeführt, die dann in den persönlichen Treffen zur Finalisierung vorgelegt werden. Als Anwendungsbereiche von besonderem Interesse wurden definiert: Klinische Routine, Forschung im Gesundheitswesen, klinische Forschung, Analyse von Sekundärdaten und Gesundheitsökonomie. Inzwischen sind 245 Einzelentscheidungen genehmigt worden.

Schlussfolgerungen

Auf der Grundlage eines nationalen gemeinsamen Prozesses, an dem die medizinischen Fachgesellschaften, die Pflegegruppen, die deutschen Krankenkassen und die Gesundheitspolitik beteiligt sind, konnte ein kontinuierlicher Entscheidungsprozess über Standards zur Ergebnismessung und -interpretation etabliert werden. Die auf Delphi-Konsensusrunden basierenden Entscheidungsprozesse wiesen hohe Beteiligungsquoten auf und stellen damit ein valides und robustes Normenwerk dar. Erste Ergebnisse befinden sich im Abstimmungsprozess mit den Gesellschaften. Die Umsetzung der Ergebnisse wird dann entscheidend sein.
