Complications associated with subsequent tunneled central venous access device placement in children: a retrospective cohort study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Central venous access devices (CVADs) are vital instruments in pediatric healthcare, enabling the administration of critical treatments such as chemotherapy and parenteral nutrition. However, despite their advantages, CVADs carry a significant risk of complications, including infections, mechanical failures, and thrombotic events. From the current literature, it is unknown whether previous CVAD placements lead to an increased risk for complications in subsequent CVAD placements. We retrospectively analyzed data regarding tunneled, surgically implanted CVADs in children over a period of 2 years at a single tertiary pediatric center regarding their complications. Between 2021 and 2022, 328 CVAD implantations were performed in 313 children. The average age at implantation was 6.6 ± 5.5 years, while most of the patients were younger than 5 years old. During the study period, a total of 102 complications occurred in 96 patients. Most frequent complications were infections (18.29% of all implantations), followed by dislocation of the catheter tip (6.4 0%) and mechanical dysfunctions (4.27%). No patient died from a complication. The choice of catheter type (Port versus Broviac) showed a significant influence on the occurrence of complications (hazard ratio of 3.964 (95% CI 1.993-7.886; p < 0.001). The risk of infection and dislodgement was also higher when comparing Broviac with Ports implantations (infection: HR = 3.236; 95% CI 1.239-8.454; p = 0.017; dislodgement: HR = 5.781; 95% CI 1.229-27.193; p = 0.026). Cox regression showed a statistically significant higher risk of complications (especially infections) when the catheter was inserted via venous cutdown instead of percutaneous puncture technique (complications: HR = 6.709; 95% CI 1.776-25.337; p = 0.005; infections: HR = 7.28; 95% CI 1.096-48.379; p = 0.04). Cox regression did not show a statistically significant influence on complications for neither of the following factors: age, gender, weight, and oncological/non-oncological diagnosis. The complication rate for patients with previous CVAD was nearly the same as for patients who received a CVAD for the first time (previous CVAD: 29.17%; no previous CVAD: 30.74%).
conclusionOur study challenges conventional assumptions regarding the impact of previous CVAD placements on complication rates. Nevertheless, ongoing vigilance and adherence to standardized protocols remain crucial in mitigating risks and improving outcomes in pediatric CVAD management. WHAT IS KNOWN: • Risk factors predisposing for CVAD-related complications remain insufficiently understood. • It is unknown whether previous CVAD placements lead to an increased risk for complications in subsequent CVAD placements. WHAT IS NEW: • The complication rate for patients with previous CVAD appears to be the same as for patients who receive a CVAD for the first time.
