[How can we optimize medical orderings in intensive care unit (ICU)?].

Objectives: To evaluate whether intensivists would accept to optimize their orderings of biological samplings, x-rays and target drugs and to assess the consequence on patient's outcome.

Study Design: Monocentric evaluation of medical economic procedure.

Methods: Meetings of consultants, registrars and residents started on Dec 21, 2006 with two to three sessions a year in order to evaluate the process of medical ordering. The physicians and pharmacists gave the results of orderings at each meeting. Orderings of systematic samplings, bedside x-rays and unjustified expansive drugs were discouraged, but target samplings and lung ultrasonography were encouraged. New residents were systematically taught about this programme. Meanwhile, monthly morbidity-mortality meetings were pursued in order to assess the consequences of this politics.

Results: While ICU total production increased by 3.4% and potentially evitable deaths decreased by 34%, annual expenses decreased by approximatively € 777,000 from 2006 to 2008. This was due to decreased orderings in biology by 30%, bedside x-rays by 10%, computed tomographic scans by 16% and target drugs by 35%. However, an increased ordering in four target drugs was observed in 2008 as compared with 2007.

Conclusion: Multidisciplinary optimization of medical ordering can be efficient in ICU. However, a profit-sharing with ordering physicians would be necessary to prolong these effects.
