Hospital Management System

Overview

This project provides a feature-rich Hospital Management System designed to streamline hospital operations, including patient and doctor management, emergency handling, and data persistence. The system leverages intelligent algorithms to assign doctors to patients based on specialties and workload while supporting priority queue handling and visit history tracking.

Files in the Repository

1. hospital_management.c: The main program for managing the hospital, including all user interactions and system operations.
2. generate_data.c: A utility program for generating a dummy dataset (hospital_data.bin) that is used by the main program.

Features

hospital_management.c (Main Program)

• Patient Management:

  • Add, remove, and display patient records.
  • Track and view patient visit history.
  • Assign doctors to patients intelligently based on specialty and workload.

• Doctor Management:

  • Add and remove doctors.
  • Monitor doctor availability and performance (patients attended).
  • Reassign patients from busy doctors to available ones.

• Priority Queue:

  • Handle emergency and regular patient queues efficiently.
  • Process patients based on priority (emergency cases prioritized).

• Data Persistence:

  • Save all hospital data (patients, doctors, queues) to a binary file (hospital_data.bin).
  • Load data from the file to resume previous sessions.

generate_data.c (Dummy Data Generator)

• Initializes a dataset with sample doctors and patients.
• Automatically assigns patients to doctors based on specialty and workload.
• Creates a hospital_data.bin file for use by the main program.

Data Structures Used

1. Structs:

   • struct Doctor: Stores doctor details such as ID, name, specialty, availability, and patients attended.
   • struct Patient: Stores patient details, including ID, name, age, disease, emergency status, assigned doctor ID, and visit history.
   • struct VisitRecord: Tracks a patient’s visit history with the doctor’s name and notes for each visit.

2. Arrays:

   • Used to store lists of patients and doctors (struct Patient patients[MAX_PATIENTS] and struct Doctor doctors[MAX_DOCTORS]).
   • struct VisitRecord arrays are used to store a patient’s visit history.

3. Priority Queue:

   • Implemented for managing the waiting queue, prioritizing emergency patients over regular ones.
   • Structure:

     struct PriorityQueue {
         int front, rear;
         struct {
             int patientId;
             int priority;  // 1 for emergency, 0 for common
         } items[MAX_PATIENTS];
     };

   • Operations:
     • Enqueue: Adds patients to the queue based on their priority.
     • Dequeue: Removes the highest-priority patient from the queue.

4. Hashing:

   • Hash function: id % MAX_PATIENTS for quick indexing of patients in the array.
   • Used for efficient patient lookup and addition while resolving collisions via linear probing.

How to Run

1. Compile the files:

   gcc hospital_management.c -o hospital_management
   gcc generate_data.c -o generate_data

2. Generate Dummy Data: Run the generate_data executable to create the hospital_data.bin file:

   ./generate_data

3. Run the Main Program: Use the hospital_management executable to interact with the system:

   ./hospital_management

Usage Instructions

1. Patient Record Management:

   • Add new patients or remove existing ones.
   • View detailed patient records, including visit history.
   • Assign patients to doctors intelligently.

2. Doctor Management:

   • Add or remove doctors from the system.
   • Monitor doctor availability and track their performance.

3. Waiting Queue Management:

   • Add emergency or regular patients to the waiting queue.
   • Process the queue based on patient priority.

4. Save and Exit:

   • Save all changes to the hospital_data.bin file to preserve continuity.

Example Outputs

generate_data.c

Upon execution, this program generates a sample dataset and outputs patient-doctor assignments. For example:

Patient 101 (Amit Mehta): Assigned to Dr. Rajesh Kumar (Specialty: General Medicine)
Patient 109 (Rajiv Bhatia): Assigned to Dr. Suresh Iyer (Specialty: Cardiology)
...
