Details and patient eligibility

About

The administration of medication, fluid resuscitation, or even nutrition in intensive care unit (ICU) patients, requires one or more infusion lines which can be peripheral or central. Midline catheter is a 10 to 20 cm long peripheral venous catheter, which can be used for up to 28 days. These features make it a good alternative to central venous and conventional peripheral venous catheters.

Midlines are routinely used in the ICU of Lorient Hospital, currently inserted by doctors. In association with the Regional Health Agency, the investigators are currently implementing a project of task delegation to ICU nurses, so that they could insert Midlines' catheters. The aim of the study is to increase the use of Midlines in the unit to reduce the exposure to central venous catheters and their complications, such as infections or thrombosis.

The investigators propose to conduct a prospective monocentric study to compare the frequency of Midlines'use, before and after the task delegation. The primary objective is to compare the duration of exposure to central venous catheters between the two periods. Secondary objectives are to compare the duration of exposure to peripheral venous catheters and Midlines, and the catheter-related infections and thrombosis.

Full description

The administration of medication, fluid resuscitation, or even nutrition in intensive care unit (ICU) patients, requires one or more infusion lines which can be peripheral or central. Although central venous catheters (CVC) are often mandatory in ICU, the risk of catheter-related infections should lead to consider the insertion of peripheral venous catheters. However in ICU patients, presence of edema or poor venous condition may not allow placement of peripheral venous catheter.

Midline catheter is a 10 to 20 cm long peripheral venous catheter, which can be used for up to 28 days (according to manufacturer recommendations). These features make it a good alternative to central venous and conventional peripheral venous catheters. They are placed at the bedside, peripherally into the cephalic or basilic vein, with the tip reaching the axillary vein.

Midlines are routinely used in the ICU of Lorient Hospital, currently inserted by doctors. Studies have shown the feasibility and the safety of delegating to nurses placement of CVC and Midlines. In association with the Regional Health Agency, the investigators are currently implementing a project of task delegation to ICU nurses, so that they could insert Midlines' catheters.

Midlines' implementation has been associated with a decrease in the use of CVC and catheter-related infections. To our knowledge, no study investigated the placement of Midlines by nurses in the ICU.

The investigators propose to conduct a prospective monocentric study to compare the frequency of Midlines' use, before and after the task delegation. The primary objective is to compare the duration of exposure to central venous catheters between the two periods. Secondary objectives are to compare the duration of exposure to peripheral venous catheters and Midlines, and the catheter-related infections and thrombosis. Complications related to Midlines' placement would also be recorded.

Trial design

310 participants in 2 patient groups
