Personalized technologist dose audit feedback for reducing patient radiation exposure from CT.

Purpose: The aim of this study was to determine whether providing radiologic technologists with audit feedback on doses from CT examinations they conduct and education on dose-reduction strategies reduces patients' radiation exposure.

Methods: This prospective, controlled pilot study was conducted within an integrated health care system from November 2010 to October 2011. Ten technologists at 2 facilities received personalized dose audit reports and education on dose-reduction strategies; 9 technologists at a control facility received no intervention.

German general practitioners' views on their involvement and role in cancer care: a qualitative study.

Background: The multidisciplinary and sequential nature of cancer care makes continuity of care for patients difficult. Cancer patients have often known their general practitioners (GPs) for years and are often in constant contact with them. Objective(s).

Involvement of general practitioners in palliative cancer care: a qualitative study.

Purpose: General practitioners play an important role in palliative care for cancer patients. The intensity of care and its medical complexity make palliative care a demanding task for general practitioners. This study explored general practitioners' perceptions of their involvement in palliative cancer care and the constraints they confront.

The use of computed tomography in pediatrics and the associated radiation exposure and estimated cancer risk.

Importance: Increased use of computed tomography (CT) in pediatrics raises concerns about cancer risk from exposure to ionizing radiation.

Objectives: To quantify trends in the use of CT in pediatrics and the associated radiation exposure and cancer risk.

Design: Retrospective observational study.

Use of diagnostic imaging studies and associated radiation exposure for patients enrolled in large integrated health care systems, 1996-2010.

Context: Use of diagnostic imaging has increased significantly within fee-for-service models of care. Little is known about patterns of imaging among members of integrated health care systems.

Objective: To estimate trends in imaging utilization and associated radiation exposure among members of integrated health care systems.
