1️⃣ Objective
The objective of this capstone is to design and implement a comprehensive Hospital/Clinic Management System (HMS/CMS). This system will digitize and integrate critical operational workflows, including patient registration, appointment scheduling, Electronic Health Records (EHR) management, inventory tracking (pharmacy/equipment), and billing processes. The goal is to enhance administrative efficiency, improve patient care coordination, and ensure data security and compliance.
Key Goals:
✨ Patient & Appointment Scheduling: Implement a responsive system for booking, rescheduling, and managing patient flow.
✨ Electronic Health Records (EHR): Create a secure module for doctors to record patient history, diagnoses, prescriptions, and lab results.
✨ Inventory and Pharmacy Management: Track medication stock, expiry dates, and automated low-stock alerts.
✨ Integrated Billing & Invoicing: Generate accurate invoices based on procedures, prescriptions, and consultation fees.
✨ Role-Based Access Control (RBAC): Ensure strict separation of access between Reception, Doctors, Pharmacists, and Administrators to maintain patient confidentiality (HIPAA/GDPR consideration).
2️⃣ Problem Statement
Many smaller clinics and hospitals still rely on paper-based records or fragmented software systems, leading to severe issues: patient record retrieval delays, errors in manual prescription writing, inefficient appointment scheduling leading to long wait times, and difficulty in auditing medication inventory. These inefficiencies compromise both the quality of care and the facility’s financial health.
This project aims to deliver a unified, secure, and intuitive digital solution that centralizes all administrative and clinical data, drastically reducing operational errors, streamlining patient visits, and providing management with necessary data analytics.
3️⃣ Methodology
The project will employ an Agile/Scrum methodology, developing modules in stages:
✨ Stage 1 — Registration & Core Data Model: Design and implement the secure database schema for Patient Demographics and Staff details. Develop the front desk module for fast check-in/out.
✨ Stage 2 — Scheduling & Appointment Logic: Build the calendar-based appointment system for doctors and patients, including reminder functionality.
✨ Stage 3 — EHR (Digital Charting): Develop the core doctor interface for writing notes (SOAP format), assigning diagnoses (ICD-10 codes), ordering tests, and electronic prescribing.
✨ Stage 4 — Inventory & Financials: Implement modules for stock management (FIFO/LIFO), automatic billing calculation based on services rendered, and payment processing records.
✨ Stage 5 — Security & Reporting: Finalize RBAC configuration, implement data encryption mechanisms, and develop dashboards for financial performance and clinic utilization.
4️⃣ Dataset
Core Entities:
✨ Patient: Demographic and personal medical history data.
✨ Encounter/Visit: Details of each patient visit (Date, Doctor, Reason).
✨ Medical Record: Consultation notes, Diagnosis (ICD), and Procedure codes (CPT).
✨ Prescription: Medication, dosage, frequency, and dispensing status.
✨ Inventory: Stock levels, supplier details, and purchase history for drugs/supplies.
Patient Records Table (Sample):
5️⃣ Tools and Technologies
6️⃣ Evaluation Metrics
✨ Average Patient Wait Time: Reduction in time from check-in to consultation (target: -25%).
✨ Billing Accuracy Rate: Percentage of invoices generated without manual correction (target: > 98%).
✨ EHR Retrieval Time: Time taken for a physician to pull a patient’s complete history (target: < 3 seconds).
✨ Inventory Variance: Discrepancy between system stock count and physical count (target: < 1%).
✨ System Uptime & Response: Reliability of the core system and API response time (target: 99.9% uptime).
