Article: [Portable coagulometers: a systematic review of the evidence on self-management of oral anticoagulant treatment].
[show abstract] [hide abstract]
ABSTRACT: We aimed to systematically review the scientific evidence about the use of portable coagulometers for patient's self-management of oral anticoagulant treatment. Systematic review of scientific evidence available from MEDLINE'S, DARE's, HTA-Database's, NHS-EED's and The Cochrane Library' s bibliographic databases, from their origin to March 2003. Randomized control trials (RCT) and Quasi-Experimental trials were selected provided that they compared patients in self-management with patients under usual care. The quality of scientific evidence was elicited using the Scottish Intercollegiate Guideline Network (SIGN) recommendations, whilst efficacy and security were descriptively summarized. Twelve (7 RCT and 5 quasi-experimental trials) articles were found, and only two of them provided grade A recommendation. Patients under self-management remained the same or more time in the therapeutic range. The incidence of adverse effects in self-management patients was the same or less than that in patients under usual care. The quality of the scientific evidence is heterogeneous. For selected patients, patient's self-management is at least as effective and safe as usual care. New oral anticaogulants, which have shown promising results, should be scrutinized for future changes in service provision.Medicina Clínica 04/2005; 124(9):321-5. · 1.38 Impact Factor -
Article: [A tool (corrected) for the critical appraisal of epidemiological cross-sectional studies].
[show abstract] [hide abstract]
ABSTRACT: The aim was to develop a tool for the critical appraisal of epidemiological cross-sectional studies. Several recommendations or guidelines for assessing the strength of scientific evidence provided by observational studies were reviewed, like those from the Agency for Healthcare Research and Quality, the Scottish Intercollegiate Guidelines Group, the Osteba (Basque Office for Health Technology Assessment), and the STROBE Initiative. The tool has 27 items to assess: study question or objective, participants, comparability between groups, definition and measure of main variables; analysis and confusion, results, conclusions, external validity and applicability, and conflict of interest. This tool can be used to critically appraise research papers or to rate evidence during the elaboration of systematic reviews.Gaceta Sanitaria 22(5):492-7. · 1.33 Impact Factor
