RESUMO
BACKGROUND: The National Institute of Health and Clinical Excellence provides a web-based resource, Clinical Knowledge Summaries (CKS), whose aim is to give evidence-based guidance for primary care practitioners and students. Included in the information it provides, are tools for the classification of conditions. OBJECTIVES: The objective of this study was to measure the proportion and utility of the classification tools that have implications for management. METHODS: Each topic on the CKS website was screened in alphabetical order for the presence of a classification tool. The linkage to management and the strength of recommendations were extracted by 2 researchers working independently. Disagreements were resolved through discussion. RESULTS: Classification tools were present for 35 conditions. There were 52 tools in all. A strong recommendation for their use was made in 37% while for a sizeable minority, 46%, the strength of recommendation was uncertain. There was a relation between strength of recommendation and linkage: for the stronger recommendation, 76% had some form of implication for management. CONCLUSION: Relevance is an important feature of a guideline for general practitioners (GPs). Given that nearly half its tools have no utility in guiding management, CKS may need to consider whether extraneous information should be disposed of or retained.
The National Institute for Health Care and Excellence provides web-based guidance on good medical care, Clinical Knowledge Summaries (CKS). It is aimed at general practitioners and other clinicians in primary care. The information includes tools with which to classify conditions. The researchers found that only 56% of classifications were linked to management decisions. It is suggested CKS should consider whether or not to continue the inclusion of classifications that lack impact.
