A new framing approach in guideline development to manage different sources of knowledge

From the EBM pyramid to the Greek temple: a new conceptual approach to Guidelines as implementation tools in mental health

Guideline methods to develop recommendations dedicate most effort around organising discovery and corroboration knowledge following the evidence-based medicine (EBM) framework. Guidelines typically use a single dimension of information, and generally discard contextual evidence and formal expert knowledge and consumer's experiences in the process. In recognition of the limitations of guidelines in complex cases, complex interventions and systems research, there has been significant effort to develop new tools, guides, resources and structures to use alongside EBM methods of guideline development. In addition to these advances, a new framework based on the philosophy of science is required. Guidelines should be defined as implementation decision support tools for improving the decision-making process in real-world practice and not only as a procedure to optimise the knowledge base of scientific discovery and corroboration. A shift from the model of the EBM pyramid of corroboration of evidence to the use of broader multi-domain perspective graphically depicted as 'Greek temple' could be considered. This model takes into account the different stages of scientific knowledge (discovery, corroboration and implementation), the sources of knowledge relevant to guideline development (experimental, observational, contextual, expert-based and experiential); their underlying inference mechanisms (deduction, induction, abduction, means-end inferences) and a more precise definition of evidence and related terms. The applicability of this broader approach is presented for the development of the Canadian Consensus Guidelines for the Primary Care of People with Developmental Disabilities.

Recommendations for symptom management in women with vulvar neoplasms after surgical treatment: An evidence-based guideline

PURPOSE

To develop an evidence-based guideline for nurses and other health care professionals involved in pre- and postsurgical care of women with vulvar cancer (VC) or vulvar intraepithelial neoplasia (VIN).

METHODS

This evidence-based guideline was developed according to six domains of the methodological framework AGREE II. Literature research with focus on cancer care, symptom management and self-management/counselling was conducted from April to August 2013 in the databases CINAHL, Cochrane Library, PsycINFO, PubMed as well as in 14 international guideline databases. Interdisciplinary experts (n = 14) were involved in the development of the guideline from December 2013 to January 2014. This guideline is currently tested in the WOMAN-PRO II RCT (Clinical Trial No: NCT01986725).

RESULTS

For the definition of recommendations, five guidelines, one meta-analysis, two systematic reviews and two randomized controlled trials were included. In total, 24 recommendations were formulated to answer 22 clinical questions based on patients' perspective and experts' opinion. Evidence ranged from 3.5 to 5 (3.5 = weak evidence and/or clinical relevance, 5 = best evidence and/or clinical relevance). The recommendations were subsumed under different themes regarding physical, psychological and psychosocial aspects.

CONCLUSIONS

The clinical practice guideline developed in this study firstly provides recommendations for symptom management issues focusing on self-management interventions for women with VC or VIN. As an interdisciplinary guideline it should be used in addition to the existing medical guideline in the German speaking context.
