Immediate Mechanical Complications After Central Venous Catheterization

The goal of this observational study is to determine the incidence of immediate mechanical complications after central venous catheterization and to explore factors associated with major mechanical complications in adolescent and adult patients undergoing central venous catheter insertion in routine clinical care. The main questions it aims to answer are: What is the incidence of immediate mechanical complications, including major complications, following central venous catheterization? Which patient-, operator-, and procedure-related factors are associated with major mechanical complications? To what extent can these factors be combined to estimate the risk of major mechanical complications before catheter insertion? This study builds on a previous multicentre registry study of central venous catheterization but includes a substantially larger number of catheter insertions. An additional exploratory objective is to assess the feasibility of developing a risk estimation model (CATH-RISK) for major mechanical complications based on available data. Participants will have their central venous catheter insertions and related clinical data recorded in an existing clinical registry. No interventions beyond standard clinical care will be performed.
