Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Number of patients with catheter associated hematoma or bleeding	Visible bruising associated with the catheter insertion site, bleeding from the catheter insertion site or incident hemoptysis	While the catheter is in place, an average of two weeks
Other	Number of patients with catheter associated site pain	Pain in the extremity associated with the catheter	While the catheter is in place, an average of two weeks
Other	Number of patients with catheter fracture	Catheter fracture	While the catheter is in place, an average of two weeks
Other	Number of patients with temporary occlusion of the catheter	Temporary occlusion of the catheter cleared by thrombolytic agent	While the catheter is in place, an average of two weeks
Other	Catheter associated change in arm circumference	Arm circumference in centimeters (cm) measured 5 cm distal to the catheter insertion site	While the catheter is in place, an average of two weeks
Other	Serum C-reactive protein concentration	Serum measure of inflammatory status with samples taken at the time of catheter insertion and removal	While the catheter is in place, an average of two weeks
Other	Serum D-dimer concentration	Blood test to assess coagulation status with samples taken at the time of catheter insertion.	While the catheter is in place, an average of two weeks
Primary	Development of catheter related deep venous thrombosis or catheter occlusion	Occlusion of the catheter requiring removal or symptomatic venous thrombosis in the extremity with the line as indicated by a Constans Clinical Decision Score greater than or equal to 2. The range of the scale goes from -1 to 3 with higher scores representing worse outcome. One point is added to a baseline score of 0 for each of the following: indwelling venous material, localized pain, unilateral pitting edema. One point is subtracted for another diagnosis being at least as plausible as venous thrombosis.	While the catheter is in place, an average of two weeks
Secondary	Development of catheter related local phlebitis or superficial thrombophlebitis	Phlebitis as defined by a Visual Infusion Phlebitis (VIP) score greater than or equal to 2. The range of the scale goes from 0 to 5 with higher scores representing worse outcome. The values on the VIP scale are defined as follows: 0-site appears healthy; 1- One of the following: Pain near the IV site or erythema near the IV site; 2- Two of the following: Pain or erythema or swelling near the IV site; 3- All of the following: Pain, erythema, and induration near the IV site; 4- All of the following: Pain, erythema, and palpable venous cord near the IV site; 5- All of the following: Pain, erythema, palpable venous cord and fever >38 degrees centigrade. Thrombophlebitis is defined by phlebitis associated with superficial thrombosis as detected by ultrasound or venogram.	While the catheter is in place, an average of two weeks
