How often should a SQ device be changed according to protocol?

The correct choice reflects the common protocol for changing a subcutaneous (SQ) device, typically set at every 7 days. This frequency is based on minimizing the risk of complications such as infection or catheter occlusion, while still allowing enough time for effective medication delivery, particularly with devices used for continuous infusion or insulin delivery.

Standard practice emphasizes regular assessment of the site for any signs of irritation or infection, but changing the device weekly helps maintain device integrity and minimizes the risk of adverse events related to longer wear. Monitoring also ensures that the site remains healthy and that the device is functioning properly, which is crucial in settings like insulin pumps or continuous medication infusion.

In clinical settings, various factors may influence this timing, such as the patient's individual needs or specific product guidelines, but the 7-day change protocol is generally accepted for many SQ devices. Ensuring adherence to this standard helps align with best practices in vascular access management and patient safety.
