Effects of a mobile phone application for graduate nurses to improve central venous catheter care: A randomized...

To develop and test a mobile phone application (app) for graduate nurses on the use and care of central venous catheters.

A randomized controlled trial was conducted at a teaching hospital in the central east coast of Taiwan.

Recruitment occurred from 1 August 2019 -31 October 2019. All graduates (N = 90) attending a 2-week induction program attended a lecture and completed a 10-item questionnaire on central venous catheter assessment and care at the end of Week 1 (Time 1). Volunteers were then randomly allocated to receive a link to the learning app on their mobile phone (n = 39 Group A) or control condition (N = 40 Group B). One week later, all graduates completed the knowledge assessment (Time 2) and a simulated clinical assessment with a mannequin. Skills were assessed using an 11-item, direct observation of procedural skills form. Only data from consenting participants were analysed.

Compared with controls, nurses receiving the intervention reported significantly better knowledge (t = -7.98, p < .001, CI = 20.9~34.8) and skill scores (t = 2.83, p = .006, CI = 1.14~6.61). More frequent use of the mobile phone app was associated with higher knowledge (r = 0.39, p = .02, CI = 0.11~0.99) and skills (r = 0.42, p = .008, CI = 0.17~1.03).

Mobile app instruction for graduate nurses on central venous catheter care increased specific knowledge and skills compared with conventional methods of instruction.

Implementation of mobile phone application technology can be considered a feasible means to proactively provide training and education. Mobile phone apps could be developed for a range of clinical procedures and various settings. Future studies with a larger sample and a longitudinal follow-up are warranted to confirm results.
