Title:

Development of a Predictive Scale (D.A.L.T.E.) for Prevention of MARSI in Oncology Patients with Vascular Access Devices

Background

       •     Medical adhesive–related skin injury (MARSI) is a frequent but under‑recognized complication in oncology patients with central and peripheral vascular access devices.

       •     Repeated dressing changes, fragile skin, and antineoplastic therapy increase MARSI risk, yet no validated risk‑prediction tool specifically addresses vascular‑access–related MARSI in this population.

Objectives

       •     To develop a clinically applicable predictive scale (D.A.L.T.E.) to estimate a patient’s risk of developing MARSI at vascular access sites.

       •     To identify modifiable factors that can guide preventive strategies and dressing selection.

Methods

       •     Prospective observational study of adult oncology patients with central or peripheral vascular access devices in a tertiary cancer center.

       •     Baseline assessment included demographic data, comorbidities, nutritional status, treatment characteristics, skin condition, device type and site, adhesive/dressing characteristics, and care practices.

       •     Patients were monitored for the occurrence and characteristics of MARSI, classified according to international consensus definitions.

       •     Multivariable analysis identified independent predictors of MARSI; these were converted into a weighted bedside score (D.A.L.T.E.) and grouped into risk categories.

Results

       •     Several independent predictors emerged, including age‑related skin fragility, previous dermatologic disease or radiotherapy, type and frequency of adhesive/dressing use, perspiration/moisture, and specific chemotherapy regimens.

       •     The D.A.L.T.E. score stratified patients into low‑, moderate‑, and high‑risk groups with clear separation of MARSI incidence across strata.

       •     The scale was easy to apply at the bedside and could be completed in a few minutes by nursing staff.

Conclusions

       •     The D.A.L.T.E. scale provides a structured method to estimate MARSI risk in oncology patients with vascular access devices.

       •     Integration of the score into routine assessment may support individualized selection of dressings and securement methods, optimization of dressing‑change intervals, and early dermatologic referral for high‑risk patients.

       •     External validation and refinement in larger, multicenter cohorts are warranted.
