Introduction: Peripheral intravenous catheters (PIVC) are the most used invasive
devices, causing 10% catheter-related infections (CRI) in Spain. To prevent de
occurrence catheter-related complications (CRC), recommended timelines for routine
resite have been extended from 48, to 72, then to 96 hours. However, this has been
questioned by lack scientific evidence. Additionally, the closed system (COS) have
never been compared with open (MOS) in PIVC.
Methods: The COSMOS study is a prospective, randomized controlled trial that
compares the CRC-free indwell times of closed (BD NexivaTM) versus open PIVC
(VasocanTM Safety), removal only by clinical-indication, in three medical/surgical
wards of tertiary hospital. 1,199 PIVC were randomized (642 inpatients), and 300
catheters were cultured randomly.
Findings: Was followed to 104,469 catheter-hours, 54,173 in COS (n=584) and 50,296
in MOS (n=599). The mean indwell time were 239.5 hours and the median 137.08 for
COS, and 171.9 and 96 for MOS (p=0.001). In catheters that remained in situ for >24
hours, COS present a median to the event of 144.5 hours. The probability of survival to
96 hours of MOS is 79.9%. Phlebitis-rate is 12%, 31 cases/1,000 catheter-days with COS
versus 16.9%, 44.75 with MOS (p=0.004). COS produced a reduction in phlebitis-rates
of 29% (p=0.004), and a 29% reduction of relative risk of CRC (p
