Purpose: To assess the effects of a real-time feedback device and refresher sessions in acquiring and retaining chest compression skills.
Methods: Healthcare providers participated in refresher sessions at 3-time points (blocks) over 1-year. At each block, chest compression (CC) skills were assessed on an infant and adult task trainer, in one 2-min trial without feedback (blinded), and up to three 2-min trials with feedback (unblinded). Skills retention over time was explored at three time lags: 1-3, 3-6, >6 months. Data collected included chest compression rate (100-120/min), depth (4 cm for infants and 5 cm for adults), and recoil between compressions.
Results: Among 194 participants, achievement of excellent CC (≥90% of adequate compressions for all parameters) increased with feedback. Linear mixed models found significant (p < 0.05) improvement in rate, depth, and recoil. Performance between last unblinded trial in block 1 with the following blinded trial in block 2 significantly decayed in rate on both task trainers irrespective of time passed, while depth and recoil performance were maintained only for infants.
Conclusions: A real-time visual feedback device improved CC skills with better results in infants. Skills decayed over time despite two refresher sessions with feedback.
