Home infusion pharmacy quality improvement for central venous access devices using anti-reflux needleless connectors to reduce occlusions, emergency room visits, and alteplase costs.

Purpose: The study's purpose was to measure the impact of anti-reflux needleless connector usage in prevention of intraluminal thrombotic occlusions among central venous catheters, as represented by alteplase usage, in a home infusion patient population.

Methods: An18-month before-and-after cohort study of a single home infusion intervention was conducted to compare occlusion outcomes with use of two types of needleless connectors-neutral and anti-reflux-in preventing catheter occlusions, which have been reported to occur in 28% of home infusion patients, resulting in treatment delays, increased nursing encounters and emergency room visits, and higher overall pharmacy costs for supplies and alteplase.

Results: A total of 552,707 patient therapy days were studied: 42.5% in the neutral needleless connector group (n = 235,004 therapy days) and 57.5% in the anti-reflux needleless connector group (n = 317,703 therapy days). The rate of alteplase usage with neutral versus anti-reflux needleless connectors was 4.4% versus 2.2% per 1,000 therapy days, with median alteplase use of 112 (95% CI, 89-169) units versus 82 (95% CI, 68-109) units (P < 0.001). Implementation of anti-reflux connectors reduced occlusions and alteplase usage by 48%.

Conclusion: Statistical evidence demonstrated that use of anti-reflux needleless connectors with central venous access devices reduced the need for alteplase in the study population. Since 10% of patient occlusions were within 7 days after home infusion admission, future research may indicate that placement of anti-reflux needleless connectors at the time of in-hospital insertion can improve patient outcomes. This quality improvement measure reduced central catheter occlusions, alteplase costs, and the number of required nursing and emergency room visits.
