Design & Implementation of Online Doctor Appointment System

Abstract

This project focuses on the Design and Implementation of Online Doctor Appointment System (ODAS) aimed at digitizing and optimizing the conventional healthcare experience. Traditional hospital systems are often plagued by inefficiencies, including lengthy queues, manual documentation errors, and delays in obtaining medical consultations. The primary goal of this research is to develop a comprehensive, scalable, and secure web-based system to address these critical issues. The system was developed using PHP for server-side scripting, MySQL for robust data management, and front-end technologies like HTML, CSS, and JavaScript. A defining feature of this DAS is the integration of WebRTC technology, enabling secure, real-time audio-video communication between patients and doctors, thereby facilitating remote consultation and follow-up. The database structure was built using tables for doctors, users, appointments, doctor schedules, prescriptions, and call signals. Key modules include user-friendly patient registration, dynamic appointment booking and scheduling, secure messaging, digital prescription generation, and an administrator panel for system oversight. The implemented system successfully reduces patient waiting times, minimizes administrative overhead, and provides instant access to healthcare professionals. Testing confirmed the system's reliability and its ability to manage large volumes of data and concurrent real-time sessions, thereby proving its efficacy as a modern solution for efficient healthcare delivery.
