The Effect of Immediate Versus Delayed Port Access on 30-Day Infection Rate

This study compared the 30-day infection risk of chest ports accessed on the same day as placement and chest ports with delayed initial access. The aim was to evaluate a larger data set that provided evidence for the development of port access guidelines. A retrospective chart review of 3322 chest port placement procedures performed between October 15, 2003, and June 10, 2015, was conducted at the interventional radiology department of a single institution. Procedure notes and health records were reviewed to determine time of initial port access, evidence of infection within a 30-day window of port placement, and causal organism(s) of infection. The results demonstrated that 64 ports (1.93%) met infection criteria within 30 days of placement, including 30 of the 945 ports immediately accessed and 34 of the 2377 ports not immediately accessed (3.17% vs 1.43%; P <.005). Dual lumen devices had a statistically significant higher rate of infection compared with single lumen devices (P =.006). This study concluded that there is a statistically significant higher rate of infection if a port is accessed immediately versus when access is deferred to later than 24 hours after placement.
