Interventions to manage occluded central venous access devices: An umbrella review

The main objective of this umbrella review is to synthesise available evidence from systematic reviews on the effectiveness of interventions for the management of occlusions in central venous access devices. CVADS have been extensively utilised among the critically ill since the 1950s however have also been linked to an increase in catheter complications. CVAD occlusion can occur in 14%-36% of patients within 1-2 years of catheter placement and is a longstanding complication. Umbrella methodology was applied to review five healthcare databases. Databases were searched for publications from 2009 and 2022 and electronic keywords searches were conducted. The authors searched for reviews that reported on any intervention to prevent, maintain or manage patency of the central venous access devices within an acute care setting. Of the 278 articles identified from the initial search a total of 11 articles were identified. This umbrella review concluded that education enhances patient outcomes and decreases occlusion rates. Further studies are required to explore occlusion reduction strategies in relation to flushing and locking.

Assessing the impact of a new central venous access device training progam for nurses: A quasi-experimental evaluation study

BACKGROUND

Central venous access devices (CVAD) are widely used for both long- and short-term purposes within healthcare and are suitable for both hospital and community management. Training is essential in the prevention of complications such as infection.

OBJECTIVES

To assess the impact of a new standardised education programme on clinical practice and patient care. The new education programme was introduced to all registered nurses working in one care group within an acute healthcare Trust with the aim of improving knowledge and skills and reduce CVAD-related complications.

METHODS

This retrospective quasi-experimental evaluation study analyses the impact of the programme on direct patient care. Secondary data sources such as infection incidence rates and CVAD clinical audits were used to identify and measure the relationship between staff confidence, infection incidence and care audit results. Data spanning a two-year period were used to capture an accurate representation of the patient group.

RESULTS

Improvements in audited care elements and a reduction of infection incidences were evident during and after implementation of the education programme. This was reflective of the self-reported increased confidence and knowledge and skill acquisition from staff who attended the programme.

DISCUSSION

Recommendations have been made including a review of the education content to target all key elements and promotion of an end goal with regular feedback to staff reinforcing the importance. The challenge of using secondary data sources also highlighted the need for quality improvements in the current care audit process.

Quality Improvement Initiative Reduces the Occurrence of Complications in Peripherally Inserted Central Catheters

Peripherally inserted central catheters (PICCs) are commonly used to access the central venous system. However, central vascular access devices are associated with a risk of complications, which may include infection, thrombosis, occlusion, or malposition. The vascular access team of 1 midwestern hospital used a quality improvement initiative to reduce the occurrence of complications associated with PICCs. A secondary aim was to reduce the number of alteplase (Cathflo Activase; Genentech, South San Francisco, CA) doses administered. After reviewing current evidence, the vascular access team employed the Plan-Do-Study-Act cycle to document and implement changes in practice. By using a team initiative to investigate this issue, complication rates decreased and patient satisfaction improved. The thrombosis rate decreased by 67%, occlusions by 75%, and alteplase use by 87%. No infections occurred during this study.

Umbilical Venous Catheter Versus Peripherally Inserted Central Catheter in Neonates: A Randomized Controlled Trial

Peripherally inserted central catheter (PICC) and umbilical venous catheter (UVC) in terms of success rate, complications, cost and time of insertion in neonatal intensive care were compared. Neonates requiring vascular access for minimum 7 days were included. Sample size of 72 per group was determined. Trial was registered at Clinical Trials Registry of India (CTRI/2015/02/005529). Success rates of the UVC and PICC were 68.1% and 65.3%, respectively (p = 0.724). Mean (SD) time needed for PICC and UVC insertion was 34.13 (34.69) and 28.31 (17.19) min, respectively (p = 0.205). Mean (SD) cost of PICC insertion vs. UVC insertion was 60.9 (8.6) vs. 11.9 (8.7) US dollars (p < 0.0001). Commonest cause for failure of UVC was displacement [6 (8.3%)] and that for PICC was blockage [9 (12.5%)].

CONCLUSIONS

UVC is a cheaper alternative to PICC, with similar success rate, short-term complications and time needed for insertion.
