Use of crystalloids and colloids in Europe per year from 2010 to 2019: Protocol for an international descriptive...

Intravenous (IV) fluids are widely used in everyday clinical practice. In the last two decades, several trials and clinical practice guidelines have been published on the use of different types and dosages of IV fluid. This may have led to a change in clinical practice. Thus, we aim to describe the use of IV crystalloids and colloids in Europe over a 10-year period.

We will collect national or regional data on the use of IV crystalloids and colloids in European hospitals through companies and/or federal medical agencies that provide pharmaceutical data concerning the type and amount of fluids used from January 1st, 2010 to December 31st, 2019. We will use run charts to describe time trends in the use of fluids.

This study will provide insight into the use of IV fluids in Europe between 2010 and 2019. It will enable the observation of changes over time and among the different European countries and regions. This will provide information on the extent to which landmark trials and clinical practice guidelines on fluids have affected clinical practice in Europe regarding the use of IV fluids.
