Background: Emergency Medical Services (EMS) face heightened operational strain during public health crises, yet hospital management frameworks frequently overlook micro-level vulnerabilities within the transport vehicle and its operator, such as driver fatigue and unverified equipment readiness.
Objectives: This study aimed to systematically evaluate prehospital vulnerabilities, design and deploy a dual-phase Ambulance Operational Checklist targeting four foundational pillars—driver roster automation, fleet efficiency, absolute equipment preparedness, and mandated driver rest—and implement a tailored training program to bridge frontline compliance gaps.
Methods: A single-arm, quasi-experimental quality improvement initiative was conducted over a consecutive six-month period at a secondary care hospital in South India. Guided by the iterative Plan-Do-Study-Act (PDSA) framework, the intervention involved an active fleet of four vehicles and its entire workforce of Emergency Medical Technicians (EMTs) and drivers. A mandatory 2-day simulation-based workshop was paired with continuous, objective monthly Quality Assurance (QA) audits.
Results: Baseline assessments revealed critical institutional vulnerabilities, with a median technical competence score of 3/10. Following simulation-based training, median competence scores rose sharply to 9/10, representing a 200% increase in proficiency. Monthly QA audits over 6+ months demonstrated excellent longitudinal sustainability: tool compliance exceeded 95%+, dispatch delays dropped from 15–20 minutes to <10 minutes, and operational near-misses decreased by 70%. Roster automation eliminated overextended shifts, ensuring 100% adherence to an 8-hour shift ceiling and a standardized 12-hour inter-shift rest period, resulting in zero reported driver fatigue incidents.
Conclusion: Utilizing an iterative PDSA cycle to balance mechanical readiness with human factor optimization effectively transitions reactive transport pools into highly reliable, safety-first clinical logistics systems. Joint simulation-based training builds an institutional culture of Crew Resource Management, sustaining operational vigilance and frontline patient safety without attrition.
