CONTEXT AND OBJECTIVEEvidence-based clinical practice emerged with the aim of guiding clinical issues in order to reduce the degree of uncertainty in decision-making. The Cochrane Collaboration has been developing systematic reviews on randomized controlled trials as high-quality intervention study subjects. Today, physiotherapy methods are widely required in treatments within many fields of healthcare. Therefore, it is extremely important to map out the situation regarding scientific evidence within physiotherapy. The aim of this study was to identify systematic reviews on physiotherapeutic interventions and investigate the scientific evidence and recommendations regarding whether further studies would be needed.TYPE OF STUDY AND SETTINGCross-sectional study conducted within the postgraduate program on Internal Medicine and Therapeutics and at the Brazilian Cochrane Center.METHODSSystematic reviews presenting physiotherapeutic interventions as the main investigation, in the Cochrane Reviews Group, edition 2/2009, were identified and classified.RESULTSOut of the 3,826 reviews, 207 (5.41%) that fulfilled the inclusion criteria were selected. Only 0.5% of the reviews concluded that the intervention presented a positive effect and that further studies were not recommended; 45.9% found that there seemed to be a positive effect but recommended further research; and 46.9% found that the evidence was insufficient for clinical practice and suggested that further research should be conducted.CONCLUSIONOnly one systematic review (“Pulmonary rehabilitation for chronic obstructive pulmonary disease”) indicated that the intervention tested could be used with certainty that it would be effective. Most of the systematic reviews recommended further studies with greater rigor of methodological quality.

<p>Cochrane-systematiske oversikter oppleves ofte som lite tilgjengelige. En av hovedaktivitetene til det norske Cochrane-miljøet er å utvikle måter å presentere resultatene fra Cochrane-oversikter på for at de lettere tas i bruk. Vi beskriver her fire hovedprinsipper for dette arbeidet, og gir eksempler på dokumentformater vi har vært med på å utvikle. De overordnete prinsippene er: 1) Informasjonen bør være forståelig for personer uten ekspertkunnskap om forskningsmetodikk. Vi har erfart at når det gjelder forståelsen av resultater fra systematiske oversikter går det største skillet mellom forskere og ikke-forskere og i mindre grad mellom ulike grupper som helsepersonell, pasienter og byråkrater. 2) Informasjonen bør presenteres på en mest mulig nøytral måte. 3) Informasjonen bør være brukertilpasset. Det innebærer at vi innhenter tilbakemeldinger fra sluttbrukere i utviklingsarbeidet og gjør nødvendige tilpasninger i flere omganger. 4) Informasjonsstrukturen bør følge ”1:3:25-prinsippet”. Her presenteres informasjonen både summarisk (1 side), kort oppsummert (3 sider), og mer utdypende (25 sider). I artikkelen beskriver vi flere presentasjonsformater vi har utviklet, blant annet ”Summary of Findings” der resultatene av Cochrane-oversikter presenteres i lettfattelige tabeller; ”plain language summaries”, som er tekstbaserte oppsummeringer rettet mot en bred lesergruppe; ”SUPPORT summaries” rettet mot byråkrater og ”policymakers”; og ”DECIDE Frameworks” der resultatene presenteres sammen med annen informasjon som er relevant i en beslutningsprosess.</p><p>Glenton C, Rosenbaum S. <strong>Cochrane in Norway – How do we disseminate findings from Cochrane reviews?</strong> <em>Nor J Epidemiol</em> 2013; <strong>23</strong> (2): 215-219.</p><p><strong>ENGLISH SUMMARY</strong></p><p>Cochrane systematic reviews are often perceived as inaccessible. One of the main activities of the Norwegian branch of the Cochrane Collaboration is to develop ways to present the results of Cochrane reviews so that they are easier to use. In this paper we describe four main principles that underlie this work, and several of the document formats we have helped produce. Our overarching principles: 1) Information should be understandable for people who do not have expert knowledge about research methodology. When it comes to understanding the results of systematic reviews, we have experienced that the biggest difference is between researchers and non-researchers and to a lesser extent between health personnel, patients and policy makers. 2) Information should be presented in a neutral form. 3) Information should be developed using a user-oriented approach. This involves us collecting responses from the end users in our developmental work and making the necessary adjustments in several phases. 4) The information structure should follow the “1:3:25 principle” where the information is structured in several layers, with increasing level of detail. In this paper, we describe several of the document formats that we have helped develop, including Summary of Findings tables, where we present the results of Cochrane reviews in tables; a plain language summary format where the results are presented as text-based summaries written for a broad user group; SUPPORT summaries written for policy makers; and DECIDE Frameworks, where the results are presented together with other information that may be relevant in a decision making process.</p>

Background: The international Cochrane Skin group, established in 1997, organizes, writes and disseminates systematic reviews of therapeutic interventions in dermatology. ObjectiveTo introduce the Cochrane Skin Group and what it offers to cutaneous medicine and surgery providers. Methods: Descriptive review of the structure and output of the Cochrane Collaboration Library and the Cochrane Skin Group. Results: Systematic reviews of randomized controlled trials produced through the Cochrane Skin Group provide a benchmark for evidence summaries for informing clinical decisions in dermatology. Conclusion: The work performed by the Cochrane Skin Group is an important component for informing the evidence base for the clinical practice of cutaneous and surgical dermatology.

ABSTRACTBackgroundThe Cochrane Collaboration has been publishing systematic reviews in the Cochrane Database of Systematic Reviews (CDSR) since 1995, with the intention that these be updated periodically.ObjectivesTo chart the long-term updating history of a cohort of Cochrane reviews and the impact on the number of included studies.MethodsThe status of a cohort of Cochrane reviews updated in 2003 was assessed at three time points: 2003, 2011, and 2018. We assessed their subject scope, compiled their publication history using PubMed and CDSR, and compared them to all Cochrane reviews available in 2002 and 2017/18.ResultsOf the 1,532 Cochrane reviews available in 2002, 11.3% were updated in 2003, with 16.6% not updated between 2003 and 2011. The reviews updated in 2003 were not markedly different to other reviews available in 2002, but more were retracted or declared stable by 2011 (13.3% versus 6.3%). The 2003 update led to a major change of the conclusions of 2.8% of updated reviews (n = 177). The cohort had a median time since publication of the first full version of the review of 18 years and a median of three updates by 2018 (range 1–11). The median time to update was three years (range 0–14 years). By the end of 2018, the median time since the last update was seven years (range 0–15). The median number of included studies rose from eight in the version of the review before the 2003 update, to 10 in that update and 14 in 2018 (range 0–347).ConclusionsMost Cochrane reviews get updated, however they are becoming more out-of-date over time. Updates have resulted in an overall rise in the number of included studies, although they only rarely lead to major changes in conclusion.

Objective Given the international focus and rigorous literature searches employed in Cochrane systematic reviews, this study was undertaken to evaluate strategies employed in Cochrane reviews and protocols assessing acupuncture as a primary or secondary intervention. Methods The Cochrane Collaboration of systematic reviews was searched in February 2009 for all reviews and protocols including information on acupuncture. Information was abstracted from all retrieved articles on review status, type and number of English and Chinese language databases searched, participation of at least one Chinese speaking author and language restriction. Frequencies were calculated and bivariate analyses were performed stratifying on interventions of interest to assess differences in search strategy techniques, language restrictions and results. Results The search retrieved 68 titles, including 48 completed reviews, 17 protocols and three previously withdrawn titles. Acupuncture was the primary intervention of interest in 44/65 (67.7%) of the retrieved reviews and protocols. While all articles searched at least one English language database, only 26/65 (40.0%) articles searched Chinese language databases. Significantly more articles where acupuncture was the primary intervention of interest searched Chinese language databases (53% vs 9%, p<0.01). Inconclusive findings as to the effectiveness of acupuncture were found in 28/48 (58.3%) of all completed reviews; this type of finding was more common in reviews which did not search any Chinese language databases. Conclusions It is important for reviews assessing the effectiveness of acupuncture to search Chinese language databases. The Cochrane Collaboration should develop specific criteria for Chinese language search strategies to ensure the continued publication of high-quality reviews.

Objective: The purpose of this article is to present the current status and future needs of old age psychiatry in relation to evidence-based health care. Method: The opportunities and difficulties of evidence-based medicine as applied to old age psychiatry are described. Depression is used as a specific example. The role of the Cochrane Collaboration and of clinical guidelines in dealing with these difficulties are discussed. Results: There has been a tendency for drug studies to focus on younger age groups and to exclude patients with comorbidity or polypharmacy. Aspects of clinical management separate from drugs are given insufficient attention. The generalizability of current studies is a problem in old age psychiatry. Conclusions: Psychiatry is no less part of medicine than any other specialty. Increased attention to studies of effectiveness, as opposed to efficacy, is indicated. The Cochrane Collaboration is an international network which promotes and conducts systematic reviews of the effectiveness of health care. Systematic reviews can increase the generalizability of the current knowledge base and better define the needs for future research.
