Computer aids and human second reading as interventions in screening mammography: two systematic reviews to compare effects on cancer detection and recall rate
No full textBackground: There are two competing methods for improving the accuracy of a radiologist interpreting screening mammograms: computer aids (CAD) or independent second reading.
Methods: Bibliographic databases were searched for clinical trials. Meta-analyses estimated impacts of CAD and double reading on odds ratios for cancer detection and recall rates. Sub-group analyses considered double reading with arbitration.
Results: Ten studies compared single reading with CAD to single reading. Seventeen compared double to single reading. Double reading increases cancer detection and recall rates. Double reading with arbitration increases detection rate (CI: 1.02-1.15) and decreases recall rate (CI: 0.92-0.96). CAD does not have a significant effect on cancer detection rate (CI: 0.96-1.13) and increases recall rate (95% CI: 1.09-1.12). However, there is considerable heterogeneity in the impact on recall rate in both sets of studies.
Conclusion: The evidence that double reading with arbitration enhances screening is stronger than that for single reading with CAD
Les difficultés pratiques des communautés de pratique.
No full textNous analysons les difficultés liées à une tentative de "mise en œuvre" de communautés de pratique au sein d'une organisation hiérarchique. Nous nous intéressons plus particulièrement aux enjeux de pouvoir susceptibles de remettre en cause les communautés de pratique comme espaces d'apprentissage interstitiel. La recherche repose sur l'étude de quatre communautés de pratique au sein d'une même entreprise. L'étude est réalisée au moyen d'entretiens semi- directifs. Les résultats montrent les difficultés rencontrées, en particulier en raison du système de management de l'entreprise et de l'enjeu de pouvoir que représentent les communautés de pratique. Sur les quatre cas étudiés, un seul parvient à conserver la caractéristique fondamentale de l'auto-organisation. Dans deux autres cas, le fonctionnement devient hiérarchique et la communauté de pratique se transforme en groupe de travail. Le quatrième cas évolue vers une situation intermédiaire. De manière plus large, c'est la capacité d'une organisation hiérarchique à stimuler sans l'étouffer une forme originellement clandestine qui peut être mise en cause.Communauté de pratique; apprentissage; gestion de la connaissance; pouvoir;
