OceanMedic: Web-Based Ambulance Ship Ordering System with Integrated Vessel Data Acquisition

Abstract

Healthcare provision in archipelagic regions remains constrained by fragmented communication and significant dispatch delays in maritime emergency referrals. This study presents and empirically evaluates OceanMedic, a web-based coordination platform designed to unify ambulance ship booking, role-based dispatch workflows, and OpenStreetMap-based WebGIS with STM32-driven AIS-like telemetry for real-time vessel tracking. A quantitative within-subject evaluation (N = 50) in a controlled baseline environment compared OceanMedic against conventional phone-based coordination. OceanMedic significantly reduced mean response time from 5.48 s to 2.03 s (p < 0.001) and task completion time from 61.70 s to 4.38 s (p < 0.001). System data completeness and validity both reached 98.0% during land-based telemetry hardware testing, while maintaining sub-3-second response times for up to 10 concurrent requests. User evaluations confirmed high perceived usability (μ = 4.26) and ease of interaction (μ = 4.22), although adoption intention remained moderate (μ = 3.80) due to anticipated sea-surface operational constraints. A literature-based architectural feature comparison against GEMAR demonstrates how OceanMedic successfully extends WebGIS-based EMS paradigms from urban road networks to maritime evacuation corridors. Overall, OceanMedic provides a foundational, scalable reference framework for future archipelagic emergency medical services.
