To this end, the PICCs used by the IV team were high- flow catheters, owing to its less invasive micropuncture technique compared to a traditional PICC, allowing for easier and less bloody insertion.
The intravenous therapy team (IVTT), working mainly in
the Medical Oncology Unit, is primarily devoted to the
placement, care, maintenance and monitoring of PICCs
(Gabriel, 2005; Collaborative Intravenous Nursing Service,
2008). This group of professionals will be at the forefront of what to do and use in terms of human and material resources, with team training.

Economic impact of the establishment of IVTT
The first major difference between the PICC implemented
by IVTT and other types of catheters that can be substituted
in certain cases, is that PICCs can be placed by a nursing
assistant, who can perform alongside properly trained nurses
and interventional radiologists. In this way, the IVTT reduces
the workload and delays in implementation requests generated
by the hospital's oncology service. If the cost savings of having

The hospital set a number of outcomes indicators by which to measure the objectives of the IVTT: ■ Objective 1: ‘Training in use of high-flow PICCs by Medical Oncology Unit nurses and training of nurses from other units of the hospital.' There will be an annual vascular access seminar for all nurses interested in participating. Indicator 1 and 2 (Table 2) ■ Objective 2: ‘Inform patients of advantages and disadvantages of high-flow PICCs over other types of catheters.' PICCs are placed directly into the unit with nursing staff, allowing immediate administration of drugs, TPN, QTP, transfusions with a lower rate of complication. PICC is not without risks, as with any other invasive technique. Indicator 3 (Table 2) Figure 7. Number of PICC catheter cannulated in 2010 to date
