Implementation and Evaluation of 'Dr. LINK' Platform: A Remote Collaborative Care Platform for Trauma and Hyperbaric Oxygen Therapy in Underserved Areas

Background/Objective: Healthcare accessibility remains a critical challenge in medically underserved regions, particularly for specialized care such as trauma treatment and hyperbaric oxygen therapy (HBOT). This study aims to develop and empirically evaluate the Dr. LINK platform, a remote collaborative care system designed to bridge healthcare gaps in geographically isolated or resource-limited areas through real-time interdisciplinary medical collaboration. Methods Dr. LINK was developed as a cloud-native teleconsultation platform utilizing SaaS-based infrastructure with Zero Trust security architecture. The platform integrates Vue.js-based user interfaces, microservices backend, and seamless hospital information system (HIS) integration across three affiliated medical centers in Wonju, Yeongwol, and Sokcho. Platform effectiveness was evaluated using the modified Telehealth Usability Questionnaire (TUQ) with a 7-point Likert scale, measuring usefulness, ease of use, interaction quality, and trustworthiness. Statistical analysis was conducted using IBM SPSS Statistics Version 29.0 with appropriate parametric and non-parametric tests. Results The Dr. LINK platform successfully facilitated real-time collaborative consultations for emergency medicine and HBOT through structured data exchange, automated notifications, and dynamic consultation transfer capabilities. The platform demonstrated scalable architecture supporting multiple concurrent consultations while maintaining data security and system performance under varying clinical demands. Conclusions Dr. LINK represents a significant advancement in addressing healthcare disparities by enabling structured, secure, and scalable remote collaborative care. The platform effectively overcomes geographic and infrastructural barriers, providing a practical framework for future telemedicine implementations in specialized care domains. Continued refinement and evaluation will be essential to fully realize its potential in transforming healthcare delivery models toward greater equity and accessibility.
