[Standardized concentrations for continuous infusion-results of a nationwide survey in German intensive care units]

Continuous infusion of numerous parenteral medications is common practice in intensive care units (ICU). In contrast to some countries, there is a lack of clearly defined standardized concentrations in Germany, especially for high-risk medications designated for infusion therapy.

The goal was to collect representative data of standardized concentrations commonly used for continuous infusion in German ICUs. Results should be used to draft nationwide recommendations for standardized continuous infusions.

To determine the nationwide acceptance and preference for medications designated for continuous infusion, a questionnaire was developed and sent to the directors of 1816 ICUs in Germany. The questionnaire comprised suggestions of 59 medicinal products with 73 concentrations. In addition, participants could make their own proposals on medications and concentrations preferably used. Evaluation was performed with SurveyMonkey® and Microsoft® Excel®.

A total of 312 (17%) ICUs answered the survey. Data analyses indicate a very high acceptance rate for rate-controlled continuous infusion with standardized concentrations. More than 90% (50%) of participating physicians routinely use the top 10 (top 25) medicines listed for continuous infusion. For most medicines, one concentration could be identified.

Our survey results generate a suitable basis for a nationwide list with standardized concentrations of medicines intended for continuous infusion (usually 50 mL). Publication of such a list by the corresponding expert committees is likely to be met with broad acceptance and implementation into clinical practice can be expected.
