  • What are EvidenceUpdates ?
  • EvidenceUpdates is a service made available by the BMJ Group that incorporates the McMaster PLUS email alerting system and searchable database of best evidence from the medical literature as a new feature to the BMJ electronic product suite.

    Users of EvidenceUpdates with interests in a specific clinical problem or treatment are invited to use the openly accessible search engine to look up topics covered in the McMaster PLUS database published as far back as 2002.

    Physicians who are in general practice or primary care, internal medicine or its subspecialties are invited to register their interests so that they can receive email alerts and searching access for literature that is matched to their personal clinical interests.

  • What do the ratings in McMaster PLUS mean?
  • The current features of PLUS include:

    • systematic review of over 110 journals (including quarterly updates of the Cochrane Library) with selection of articles by expert research staff concerning the cause, course, diagnosis, prediction, prevention, and treatment of health problems, quality improvement and health economics, according to explicit criteria, with high reproducibility and periodic quality assurance checks**

    • ratings of each eligible article for clinical relevance and newsworthiness by at least 3 practitioners for each discipline for which the article might be pertinent. The McMaster Online Rating of Evidence (MORE) rating panel has >5000 participants from around the world, all in clinical practice, with about half in primary care, and the rest in internal medicine and its subspecialties, and other major specialties including pediatrics, psychiatry, obstetrics, gynecology, surgery, and anaesthesiology.

    • e-mail alerts about new evidence, tailored to the user's interest profile and adjustable for their time demands. Each alert includes MORE clinical ratings and comments, and electronic links to the article's abstract via PubMed (if available).

    • Links to fulltext articles and summaries for free fulltext articles, BMJ Group articles and Clinical Evidence topics (a subscription or fee may be needed for some of these articles and summaries).

    • Hit Parade, the articles most frequently accessed by practitioners with your interests.

    • Medical news headlines with evidence-based assessments.

    • a cumulative searchable bibliographic database of the alerts that is continuously updated (from 2003 forward).

    • a user interface allowing each user to register their health care interests, leading to matching of those interests to the appropriate "virtual" subset of the accumulating database.

    • links to evidence-based search strategies for MEDLINE to supplement searches in the cumulated PLUS database when needed.

  • Disclaimer
  • The information contained in EvidenceUpdates is intended for medical professionals and is provided on an "as is" basis without warranty of any kind, express or implied.

    EvidenceUpdates provides an educational service for practicing clinicians, designed to alert clinicians to important new research; however, we cannot warrant its accuracy. It is intended to support evidence-based decision making, by providing links to published research reports about the diagnosis, treatment, prediction and prognosis, etiology, and economics of medical conditions. However, "evidence does not make decisions"*, and clinicians making decisions about the care of their patients must take into account the limitations of evidence from research as well as the unique nature of their patients' circumstances and wishes. Readers should also be aware that professionals in the field may have different opinions about the interpretation of evidence from research. Because of this fact and also because of regular advances in medical research, we strongly recommend that readers independently verify any information they chose to rely on. Ultimately it is the readers' responsibility to make their own professional judgements.

    EvidenceUpdates attempts to provide access to the best new research of relevance for clinical practice in the fields of primary medical care and subspecialties of internal medicine. It does not report all research but uses explicit criteria to define a subset of published research that is likely to be valid and ready for clinical attention in these disciplines. Practicing physicians then provide their assessments of the relevance and newsworthiness of the reports through an online review process, the McMaster Online Rating of Evidence (MORE). Individual clinicians who then receive these reviews must then apply their own judgment concerning the strength and applicability of this evidence to their own patients.
