Brief Summary:
Midline catheter is a peripherally-inserted catheter, with the distal tip being placed into the axillary vein. For some indications, it's an alternative to the peripheral insert central catheters in case of limited venous access and infusions less than one month. The Midline catheter is poorly described in scientific literature; therefore, the aim of the study is to determinate the incidence of adverse events (Infections and thrombosis) and risk factors for patients with this device.

Thrombosis Other: Follow up of midlines

Detailed Description:

The midline is a deep peripheral venous catheter whose insertion is between the lower and upper third of the arm and whose distal end does not extend beyond the axillary vein. It requires the identification of the vein by ultrasound which reserves its installation for professionals trained and authorized to use the ultrasound scanner.

Midline is currently indicated for intravenous treatments > 7 days and in patients with precarious venous capital. According to the manufacturer's instructions, it can be kept in place for up to 30 days, while the recommendations of the Centers disease of control specify that this period could be extended to 49 days.

Its use is expanding rapidly in France, thus meeting the needs of patients who do not require a central line and whose use of a standard peripheral venous catheter is not possible (low venous capital or treatment duration > 7 days). Its installation, essentially carried out by qualified anaesthetists, does not increase medical planning and is therefore an attractive alternative to the installation of a central catheter whose complications (thrombosis and infections) are known.

The only data on the complication rate, estimated at 1-2%, are from low-potency observational studies. In the absence of high-level evidence, most of the good practice recommendations published in 2019 are based on expert consensus.

This leads us to conduct a large-scale observational study to assess the complication rate and identify the associated factors. This study will provide professionals with reliable scientific data for the next review of good practice recommendations.

Intervention Details:
  • Other: Follow up of midlines
    The follow-up data to be collected will be recorded on a monitoring logbook that will follow the patient (Appendix 4). The latter will be involved in the follow-up of his data insofar as he will be able to solicit the various professionals performing care on his midline in order to aim at the exhaustiveness of the filling of the book.

Primary Outcome Measures :
  1. assess numbers of adverse events [ Time Frame: through study completion, an average of 2 year ]
    catheter related infection yes/no vein thrombosis yes/no exposition time to a midline catheter
