Early in 2021, the Infusion Nursing Society has released the latest version of the Infusion Therapy Standards of Practice. In the last two decades, these Standards have been representing one of the most important evidence-based documents available in the world of venous access. Nevertheless, we were quite concerned reading a recommendation included in chapter 26 (Vascular Access Device Planning: practice recommendation I, C): “Use a patient’s port, unless contraindicated (e.g. existing complication) as the preferred IV route in preference to insertion of an additional VAD.” Such recommendation is offered not on the basis of evidence, but as experts’ opinion (“Committee Consensus”). This Editorial deals with the opinion of GAVeCeLT (The Italian Study Group for Long Term Central Venous Access) that strongly discourage the use of ports for intravenous treatment different from chemotherapy (or from the therapy that specifically required that long term, infrequent access). The rationale for this choice is based on the consideration that the patient’s port—if used in a non-specialty ward—would be at high risk of complications, some of them potentially leading to the loss of the device, and that such complications might be particularly difficult to manage in this setting. The continuous or frequent use of a port transforms it into an external device, thus cancelling the main advantage of a totally subcutaneous location, while adding a significant disadvantage (need for repeated percutaneous punctures and risk of extravasation/infiltration due to improper insertion or dislocation of the non-coring needle). One exception is the possible use of port for radio-diagnostic purposes (as long as the port is power injectable). This strategy may be associated with advantages for the patient, and imaging quality improvement, but requires the adoption of specific protocols for prevention of infective and mechanical complications.
Should we use a patient’s port as the preferred intravenous route rather than inserting an additional venous access?
