Cystic Fibrosis Clinical Trial
Official title:
Prospective Study of Peripherally Inserted Venous Catheters in CF Patients
According to the U.S. CF Foundation Patient Registry, more than 25% of children and 40% of adults were treated with intravenous (IV) antibiotics for flares of lung disease in 2016. Medication for these flares is often delivered through a peripherally inserted central catheter (PICC). Case series have identified important complications of PICCs in CF patients such as blood clots and infection. The frequency of PICC-associated blood clots in CF patients ranges from 2 to 8%. Catheter-related complications may interfere with completion of therapy and lead to repeated procedures and other complex medical treatments. In some cases PICC complications may discourage patients from accepting future courses of IV antibiotics. Therefore, it is very important to identify patient- and device-related factors that are linked with more frequent complications and to figure out ways to reduce these risks. Proposed risk factors fall into several broad categories. First are catheter-related factors; second are patient factors; and third are catheter-management factors. To date, no multicenter trial has carefully studied PICC complications in a large group of adult and pediatric CF patients from the time each catheter is placed to when it is removed. The main purpose of this study is to see whether the investigators can identify important factors in each of the three categories (patient, catheter, and catheter management) that are linked to various complications.
According to data from the U.S. CF Foundation Patient Registry (CFFPR), more than 25% of children and 40% of adults were treated with intravenous (IV) antibiotics for pulmonary exacerbations (PEx) in 2016; this translated to 20,286 care episodes. Case series have identified important complications of PICCs and TIVADs in CF patients such as deep venous thrombosis (DVT) and infection; central venous stenosis; and other types of mechanical dysfunction. The incidence of PICC-associated DVT in CF patients ranges from 2 to 8%. Proposed risk factors in CF patients fall into several broad categories. First are catheter-related factors: larger catheter size, number of catheter lumens, and catheter composition; second are patient factors: lung function, nutritional status, respiratory flora, diabetes status, thrombophilia; and number of previously placed catheters; and third are catheter-management factors: insertion technique and site selection, inpatient versus outpatient care, anticoagulant use, blood sampling practices, and duration of line use. The importance of some of these factors remains controversial, leading some to call for detailed prospective studies of PICC use in specific patient populations. To date, no multicenter trial has prospectively studied PICC and midline complications in adult and pediatric CF patients. The investigators hypothesize that the rate of PICC and midline vascular complications is associated with specific patient level and line level factors as well as with line insertion and management practices. The proposed trial is a multicenter, prospective surveillance study to evaluate (patient level-, catheter level- and catheter management-) risk factors associated with various complications of PICCs and midlines in pediatric and adult CF patients. ;
