Patient Management System

Introduction

Growing up, I never thought I'd find myself developing a patient management system. My childhood was spent in a small rural town where healthcare was more of a luxury than a right. Our local clinic was a small, understaffed facility that served several neighboring towns. I vividly remember the long waits, the overworked staff shuffling through stacks of paper records, and the frustration on patients' faces.One particular memory stands out. I was 12 when my grandmother fell ill. We rushed her to the clinic, only to find a chaotic scene. The receptionist couldn't locate her records, the doctor was overwhelmed with patients, and we waited for hours in uncertainty. I felt helpless, watching my grandmother's condition worsen as we waited. That day left a lasting impression on me. I promised myself that someday, I'd find a way to make things better. As I grew older and discovered my passion for technology, I realized that this could be my avenue to effect change. Years later, when I started my journey in software development, that memory resurfaced. I saw an opportunity to bridge the gap between healthcare and technology. The idea of creating a system that could streamline patient management, reduce wait times, and potentially save lives became my driving force. This project isn't just about building a cool app or showcasing my technical skills. It's about fulfilling a promise I made to myself as a 12-year-old boy, watching his grandmother suffer due to an inefficient system. It's about ensuring that no other child has to feel that same helplessness. Every line of code I write, every feature I implement, is infused with the hope that somewhere, in a small clinic like the one from my childhood, a healthcare provider will be able to access patient information quickly, schedule appointments efficiently, and provide better care. As I work on this project, I often think about that overworked receptionist, that overwhelmed doctor, and all the patients waiting anxiously. I imagine how a system like this could have changed their day, and potentially their lives. It's this vision that keeps me going, even when faced with technical challenges or late nights of debugging. This patient management system is more than just a portfolio project for me. It's a step towards fulfilling a childhood promise, a way to give back to communities like the one I grew up in, and hopefully, a means to prevent others from experiencing what my family went through that day at the clinic.

• Backend: Appwrite was chosen as our backend-as-a-service solution. It offers robust security features and simplifies HIPAA compliance, allowing us to focus on developing core functionalities rather than building backend infrastructure from scratch.

• SMS Integration: Twilio was integrated for sending appointment reminders. Its reliable API and global reach made it ideal for our needs, especially when dealing with international phone numbers.

• Error Tracking: Sentry was implemented for real-time error tracking and monitoring. This choice was made to ensure quick identification and resolution of issues in the production environment.

• Hosting: Vercel was selected for hosting due to its seamless integration with Next.js and its robust CI/CD pipeline, enabling quick and reliable deployments.

Key Features

• Secure Patient Registration and Authentication: Implemented a HIPAA-compliant registration process with secure authentication. This feature allows patients to create accounts, manage their personal information, and access their medical data securely.

• Intelligent Appointment Scheduling: Developed an advanced scheduling system that allows patients to book appointments based on provider availability. The system includes conflict detection and sends automated SMS reminders, significantly reducing no-shows and improving clinic efficiency.

• Responsive Design for Mobile Access: Created a fully responsive interface that adapts to various screen sizes, ensuring that both patients and healthcare providers can access the system efficiently from any device. This feature particularly benefits healthcare providers who need to access patient information on-the-go.

Most Difficult Technical Challenge:

“Integrating Twilio for Kenyan Phone Numbers”

Situation: Implementing SMS appointment reminders using Twilio was a crucial feature for the Patient Management System, as it would help healthcare providers and patients stay on top of scheduled appointments. However, integrating Twilio with Kenyan phone numbers proved to be a significant technical challenge.
