ThP8.5 - The Incidence and Characteristics of Complications Associated with Peripherally Inserted Central Venous Catheter and Midline Utilisation in Surgical Patients: A Retrospective Cohort Study

Abstract

Abstract Background Peripherally inserted Central venous catheters (PICC lines) and midlines are pervasive clinical interventions. However, they are not devoid of adverse events such as catheter-associated thrombosis, mechanical anomalies, catheter-related bloodstream infections, and cellulitis. This study aims to investigate the nature and prevalence of these complications within a high-volume tertiary care centre. Methods A retrospective cohort study was conducted, including 473 patients subjected to PICC line and midline insertion within the Department of General Surgery during the period from June 2022 to June 2023. Results Over 5949 catheter days, a total of 73 complications were identified, reflecting an incidence rate of 15.43% (12.27 per 1000 catheter days). Notably, catheter-associated infections were predominant, manifesting at a rate of 4.20 per 1000 catheter days (n=25, 5.20%). Accidental withdrawal occurred at a rate of 3.87 per 1000 catheter days (n=23, 4.86%), incorrect positioning at 2.02 per 1000 catheter days (n=12, 2.54%), occlusion at 1.51 per 1000 catheter days (n=9, 1.90%), and rupture at 0.67 per 1000 catheter days (n=4, 0.84%). Conclusion The insertion of PICC and midline is associated with a substantial burden of morbidity, primarily characterised by catheter-associated infections. Emphasis on early identification of catheter-associated bloodstream infections is imperative. Mitigating these complications warrants the institution of a multidisciplinary educational initiative to augment nursing proficiency, coupled with the implementation of a local guideline governing PICC line and midline insertion and care.
