Abstract
BackgroundConsensus statements and clinical practice guidelines are widely available for enhancing the care of cancer patients. Despite subtle differences in their definition and purpose, these terms are often used interchangeably. We systematically assessed the methodological quality of consensus statements and clinical practice guidelines published in three commonly read, geographically diverse, cancer-specific journals. Methods Consensus statements and clinical practice guidelines published between January 2005 and September 2013 in Current Oncology, European Journal of Cancer and Journal of Clinical Oncology were evaluated. Each publication was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) rigour of development and editorial independence domains. For assessment of transparency of document development, 7 additional items were taken from the Institute of Medicine’s standards for practice guidelines and the Journal of Clinical Oncology guidelines for authors of guidance documents.MethodsConsensus statements and clinical practice guidelines published between January 2005 and September 2013 in Current Oncology, European Journal of Cancer and Journal of Clinical Oncology were evaluated. Each publication was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) rigour of development and editorial independence domains. For assessment of transparency of document development, 7 additional items were taken from the Institute of Medicine's standards for practice guidelines and the Journal of Clinical Oncology guidelines for authors of guidance documents.FindingsThirty-four consensus statements and 67 clinical practice guidelines were evaluated. The rigour of development score for consensus statements over the three journals was 32% lower than that of clinical practice guidelines. The editorial independence score was 15% lower for consensus statements than clinical practice guidelines. One journal scored consistently lower than the others over both domains. No journals adhered to all the items related to the transparency of document development. One journal’s consensus statements endorsed a product made by the sponsoring pharmaceutical company in 64% of cases.ConclusionGuidance documents are an essential part of oncology care and should be subjected to a rigorous and validated development process. Consensus statements had lower methodological quality than clinical practice guidelines using AGREE II. At a minimum, journals should ensure that that all consensus statements and clinical practice guidelines adhere to AGREE II criteria. Journals should consider explicitly requiring guidelines to declare pharmaceutical company sponsorship and to identify the sponsor’s product to enhance transparency.
Highlights
Consensus statements and clinical practice guidelines are widely used in oncology to improve the quality of patient care [1,2]
AGREE II Rigour of development scores When assessed across all three journals (Figure 1, Table 2), the mean scores for consensus statements were 32% and for clinical practice guidelines 64%
While consensus statements and clinical practice guidelines are developed with slightly different approaches and methods, both are used to inform clinical and policy decisions
Summary
Consensus statements and clinical practice guidelines are widely used in oncology to improve the quality of patient care [1,2]. While both consensus statements and clinical practice guidelines are intended to provide guidance to clinicians, there are important differences between them. Mean difference Consensus Statement vs Clinical Practice Guideline. Consensus statements and clinical practice guidelines are widely available for enhancing the care of cancer patients. We systematically assessed the methodological quality of consensus statements and clinical practice guidelines published in three commonly read, geographically diverse, cancer-specific journals
