Background
WHO recommends training lay first responders (LFRs) as the first step toward formal emergency medical services development, yet no tool exists to evaluate LFR programs.
Methods
We developed Prehospital Emergency Trauma Care Assessment Tool (PETCAT), a seven-question survey administered to first-line hospital-based healthcare providers, to independently assess LFR prehospital intervention frequency and quality. PETCAT surveys were administered one month pre-LFR program launch (June 2019) in Makeni, Sierra Leone and again 14 months post-launch (August 2020). Using a difference-in-differences approach, PETCAT was also administered in a control city (Kenema) with no LFR training intervention during the study period at the same intervals to control for secular trends. PETCAT measured change in both the experimental and control locations. Cronbach’s alpha, point bi-serial correlation, and inter-rater reliability using Cohen's Kappa assessed PETCAT reliability.
Results
PETCAT administration to 90 first-line, hospital-based healthcare providers found baseline prehospital intervention were rare in Makeni and Kenema prior to LFR program launch (1.2/10 vs. 1.8/10). Fourteen months post-LFR program implementation, PETCAT demonstrated prehospital interventions increased in Makeni with LFRs (5.2/10, p < 0.0001) and not in Kenema (1.2/10) by an adjusted difference of + 4.6 points/10 (p < 0.0001) (“never/rarely” to “half the time”), indicating negligible change due to secular trends. PETCAT demonstrated high reliability (Cronbach’s α = 0.93, Cohen's K = 0.62).
Conclusions
PETCAT measures changes in rates of prehospital care delivery by LFRs in a resource-limited African setting and may serve as a robust tool for independent EMS quality assessment.
