Highlights Long-term catheter flushing for >90 days has preserved function. Ports cleaned after 90 days have the same colonization rate as those flushed early. Long-term catheters may be colonized in asymptomatic patients. The longer port cleaning interval reduces costs. ABSTRACT Objective: To evaluate the incidence of malfunction and colonization rates of fully implantable long-term catheters left unflushed during the COVID-19 pandemic; and to evaluate the average cost of transporting each patient to the hospital for flushing. Methods: During the COVID-19 […]
