Venous International Assessment, VIA scale, validated classification procedure for the peripheral venous system.

Purpose: VIA scale is a dynamic performance status tool of the peripheral venous system that is divided into five different grades, composed of three parameters: number of observable puncture points; optimal catheter size for cannulation and ease of performing venipuncture and risk of extravasation.

Methods: Prospective single-center, observational, open, non-randomized study divided into two phases. In the first longitudinal phase, we studied the clinical characteristics and the changes in their peripheral venous systems during intravenous chemotherapy for 16 patients (n=16) for an average period of 24 months.

Care and cost-utility indicators for high-flow PICC catheters: a study.

Intravenous therapy teams (IVTT) provide care, education and supervision of the patient with a central line, and his/her family. This article discusses the creation of an IVTT in the Hospital Clínico San Carlos of Madrid, Spain, demonstrating its effectiveness using cost-utility analysis and outcomes indicators. In 2009 the IVTT began using a high-flow peripherally inserted central catheter (PICC) with its target population of chronic patients dependent on central venous catheters or prolonged IV treatment.
