Question 1

How does SATS perform compared to ESI or MTS?

Accepted Answer

SATS has comparable validity (AUC for predicting admission 0.79–0.87) and inter-rater reliability (kappa 0.6–0.8). A key advantage in resource-limited settings is its lower reliance on technology — it uses clinical observations accessible in even the most basic facilities. It also explicitly incorporates a symptom-based override, reducing under-triage of conditions like chest pain.

Question 2

What training is required for SATS implementation?

Accepted Answer

SATS requires a 2-day training course covering the TEWS, symptom discriminators, paediatric modifications, and the triage process. Annual refresher training is recommended. The SATS training programme has been delivered in over 15 African countries and has demonstrated sustained improvement in triage accuracy.

Question 3

Is SATS validated for paediatric emergency triage?

Accepted Answer

Yes — the paediatric SATS (pSATS) uses a modified TEWS with age-adjusted respiratory rate, heart rate, and temperature thresholds for children under 12. Studies show good predictive validity for hospitalisation and mortality. pSATS is one of the few triage systems specifically validated for resource-limited paediatric populations.

Question 4

What is the evidence that SATS improves outcomes?

Accepted Answer

Implementation of SATS in South African and other sub-Saharan African EDs has been associated with a 50% reduction in mortality among triaged patients, reduced waiting times, and improved identification of critically ill patients. These outcomes demonstrate that structured triage is effective even in resource-limited environments.
