ORION Statement

The quality of research in hospital epidemiology (infection control) must be improved to be robust enough to influence policy and practice.

In order to raise the standards of research and publication, a CONSORT equivalent for these largely quasi-experimental studies has been prepared by the authors of two relevant systematic reviews undertaken for the HTA and the Cochrane Collaboration. The statement was revised following widespread consultation with learned societies, editors of journals and researchers. It consists of a 22 item checklist, and a summary table. The emphasis is on transparency to improve the quality of reporting and on the use of appropriate statistical techniques.

The statement has been endorsed and welcomed by a number of professional special interest groups and societies including the Association of Medical Microbiologists (AMM), Bristish Society for Antimicrobial Chemotherapy (BSAC) and the Infection Control Nurses' Association (ICNA) Research and Development Group. Like CONSORT, ORION considers itself a work in progress, which requires ongoing dialogue for successful promotion and dissemination. The statement is therefore offered for further public discussion and journals are encouraged to trial it as part of their reviewing and editing process and feedback to the authors.

Just as CONSORT has released guidelines and a checklist to help submitters and reviewers improve the quality of reporting of abstracts for journals and conference submissions, there is now an ORION abstract guideline which is available. This was used by SHEA for submission of abstracts to their 2011 conference. There will be a meet the experts session in Milan on Sunday 8th May which will take the from of a workshop introducing the guidelines and how to use it, by Professor Barry Cookson and Dr Sheldon Stone.

ORION WORKSHOP IFIC Meeting Budapest 2007

At the 8th Congress of the International Federation of Infection Control in Budapest in October 2007, a highly successful ORION workshop was given, with the intention of showing the 40 or so participants how to design and assess intervention studies to improve infection control and prescribing interventions. This page features the powerpoint presentation introducing ORION, two specimen papers that the particpants reviewed, and the reviewers’ ORION checklist that they used. The correct answers are given at the end of the ppt.presentation.
