Evaluating the Effectiveness of Three Different Anchoring Methods on Percutaneous Drainage Catheter: A Pilot Study

Aim: To compare the effectiveness of three different anchoring methods for percutaneous drainage catheter (PDC) in preventing accidental dislodgement, occurrence of medical adhesive-related skin injury (MARSI), ease of application, and additional anchorage changes. Methodology: Patients undergoing PDC were randomly allocated into intervention groups: medical silk tape (DP), micropore tape (MP), or securement dressing (GL). The anchoring dressing was changed once a week or when it was soiled. Weekly follow-up via a phone call was conducted for 4 weeks. Results: Fifty-four participants were recruited. There was a significant difference in MARSI for DP compared to MP (z: -2.45, p=0.014) and GL (Z-score [z]: -2.51, p=0.012). DP (median: 1) was significantly easier to apply when compared to MP (median: 3, H-score [H]: 13.30, p=0.015). There was a significant difference in additional changes required for MP (n=5, z: -2.44, p=0.015) and DP (n=4, z: -2.21, p=0.027) as compared to GL. There were no PDC dislodgements. Conclusion: This pilot study suggests that securement dressing has the lowest association with MARSI and does not require frequent changes. However, further research with a larger patient population is necessary to validate these findings, as definitive conclusions cannot be drawn from a small sample size.
