Background Several studies have documented the production of wasteful research, defined as research of no scientific importance and/or not meeting societal needs. We argue that this redundancy in research may to a large degree be due to the lack of a systematic evaluation of the best available evidence and/or of studies assessing societal needs. O...

p> Bakgrunn : Forskningsresultater kan formidles på ulike måter, både gjennom tall, tekst og kombinasjoner av disse. Utover et effektestimat er det i klinisk forskning også ønskelig å si noe om hvor sikker man er på resultatet, for eksempel ved å oppgi konfidensintervall og gjøre en vurdering av kvaliteten på dokumentasjonen. Vår hensikt med denne...
Article

Nursing home residents are prone to acute illness due to their high age, underlying illnesses and immobility. We examined the incidence of acute hospital admissions among nursing home residents versus the age-matched community dwelling population in a geographically defined area during a two years period. The hospital stays of the nursing home popu...
Article
Full-text available
The results of thousands of trials are never acted on because their published reports do not describe the interventions in enough detail. How can we improve the reporting? Much healthcare research is currently wasted because its findings are unusable.1 Published reports of intervention trials often focus on the results and fail to describe interv...

We set out to assess whether current guidance and systematic review evidence can sufficiently inform practical decisions about how to use audit and feedback to...
Article
Historically, measurement of clinical outcomes was not a feature of routine clinical practice. Physiotherapists (and, for that matter, most other health professionals) did not systematically collect data on patients' outcomes. Typically physiotherapists obtained incidental impressions of clinical outcomes from clinical observations, or from patient...
Article
Full-text available
Previous studies have shown that Norwegian public health physicians do not systematically and explicitly use scientific evidence in their practice. They work in an environment that does not encourage the integration of this information in decision-making. In this study we investigate whether a theoretically grounded tailored intervention to diffuse...
Article
In many areas of health care, randomized controlled trials (the best evidence regarding the effectiveness of health care interventions) are lacking and decision-makers have to rely on evidence from nonrandomized studies (NRS). We conducted a Medline search to identify English-language articles describing instruments for assessing the quality of NRS...
