The aim of the Best Current Knowledge Service is to
ensure that a common core of knowledge from research,
data and experience based on explicit quality standards and user needs is collected and
regularly updated
![Page 8: Patients and professionals need, and have a right to, clean, clear knowledge just as they need clean clear knowledge](https://reader033.vdocuments.site/reader033/viewer/2022061306/551469045503462d4e8b5c94/html5/thumbnails/8.jpg)
What we know -3 types of generalisable knowledge
Knowledge from research - Evidence
Knowledge from measurement of healthcare performance-Statistics
Knowledge from experience-Of patients and clinicians
These need to be linked to 2 types of particular knowledge
Knowledge about this population
Knowledge about this public health service

“For 28,737 original and review articles published in 110 journals in
2004 [ 556 (1.93%)] met critical appraisal criteria and were rated…for
relevance”

“50% of efficacy and 65% of harm outcomes were incompletely reported.86% of survey
respondents (42/49) denied the existence of unreported outcomes despite evidence to the contrary…Published articles, as well as the
reviews that incorporate them, may therefore be unreliable and over estimate the benefits of an
intervention”

The aim National Clinical Decision Support Service is to ensure that any computer based decision support system for clinicians and patients
not only use best current knowledge but also have been
demonstrated as doing more good than harm in ordinary service
settings

important in low prevalence settings where the number of false positives may exceed
the number of true positives”Booth JCL et al (2001)

The National Knowledge Service will organise National Knowledge Weeks which will
deliver Annual Reviews of Evidence, Process, Outcome
and Configuration
![Page 23: Patients and professionals need, and have a right to, clean, clear knowledge just as they need clean clear knowledge](https://reader033.vdocuments.site/reader033/viewer/2022061306/551469045503462d4e8b5c94/html5/thumbnails/23.jpg)
The Annual Evidence Analysis will be prepared by the relevant National Specialist Library and
will present the knowledge produced in the preceding year
which conforms to explicit quality standards, priority will be given to a National Library of Systematic
Reviews

Ignorance is like cholera; it cannot be controlled by the individual alone it requires the organised efforts of society; ensuring equal access to pure knowledge is a public health responsibility
