PICC Outcomes in Critically Ill Older ICU Patients

Featuring outcomes from 452 Korean ICU patients aged 60 and over who received a bedside ultrasound-guided peripherally inserted central catheter (PICC) between 2021 and 2024. It includes data on PICC-related infections, catheter tip positioning, and survival analysis with time-to-event estimates. The study identifies risk factors for non-optimal catheter tip position using logistic regression.

Use Cases

• Analyze the association between patient sex, catheter length, and insertion side with the risk of non-optimal catheter tip position using logistic regression odds ratios.
• Model PICC-related infection-free survival over time using Kaplan-Meier estimates and time-to-event data (e.g., 56.29 ± 0.98 days).
• Investigate the prevalence of PICC-related bloodstream infection (1.1%) and overall infection (2.88%) within the 452-patient cohort.
• Examine the relationship between catheter tip position (optimal in 93.1% of patients) and subsequent infection or survival outcomes.

Strengths

• Dataset includes 452 patient records from a defined clinical study.
• Provides specific statistical results, including odds ratios with confidence intervals and p-values for risk factors.
• Includes time-to-event survival analysis with mean estimates and confidence intervals (e.g., 56.29 ± 0.98 days).

Limitations

• Data is from a single, small-volume center in Korea, limiting generalizability to other populations or healthcare settings.
• The dataset is very small (5.5 KB), suggesting limited variables or aggregated summary data rather than detailed patient-level records.
• As a retrospective study, it is subject to the limitations inherent in that design, such as potential confounding factors.
