Objectives:
To evaluate the impact of a mobile-app-based central line-associated bloodstream infection (CLABSI) prevention program in oncology clinic patients with peripherally inserted central catheters (PICCs).
Design:
Pre-post prospective cohort study with baseline (July 2015-December 2016), phase-in (January 2017-April 2017), and intervention (May 2017-November 2018). Generalized linear mixed models compared intervention with baseline frequency of localized inflammation/infection and dressing peeling. Cox proportional hazards models compared days-to-removal of lines with localized inflammation/infection. Chi-square test compared bacteremia rates before and after intervention.
Setting:
Oncology clinic at a large medical center.
Patients:
Oncology clinic adult patients with PICCs.
Intervention:
CLABSI prevention program consisting of an actionable scoring system for identifying insertion site infection/inflammation coupled with a mobile-app enabling photo-assessments and automated physician alerting for remote response.
Results:
We completed 5,343 assessments of 569 PICCs in 401 patients (baseline: 2,924 assessments, 300 PICCs, 216 patients; intervention: 2,419 assessments, 269 PICCs, 185 patients). The intervention was associated with a 92% lower likelihood of having a dressing with peeling (OR 0.08, 95%CI 0.04-0.17, P < 0.001), 53% lower local inflammation/infection (OR 0.47, 95%CI 0.27-0.84, P < 0.011), and 24% (non-significant) lower CLABSI rates (P = .63). Physician mobile-app alerting and response enabled 80% lower risk of lines remaining in place after inflammation/infection was identified (HR 0.20, 95%CI:0.14-0.30, P < 0.001) and 85% faster removal of infected lines from mean (SD) 11.1 (9.7) to 1.7 (2.4) days.
Conclusions:
A mobile-app-based CLABSI prevention program decreased frequency of inflamed/infected central line insertion sites and increased speed of removal when inflammation/infection was found.
