Overall Description
These include features such as patient registration and scheduling, electronic medical records (EMRs), billing and payment processing, inventory management. EMRs are digital versions of a patient's medical record that can be accessed by authorized healthcare providers. They include information such as medical history, test results, and treatment plans. Prescription mechanisms can be a part of an EMR or a separate system altogether. Electronic prescribing (e-prescribing) systems allow doctors to send prescriptions directly to pharmacies, reducing errors and increasing efficiency. Overall, hospital management systems can help improve patient care, streamline administrative tasks, and reduce costs. They can also help hospitals comply with regulations and maintain accurate records
1.1. Introduction
Before the advent of modern computer-based hospital management systems, many hospitals used manual systems for patient registration, appointment scheduling, and prescription management. These systems were typically paper-based and often involved creating lists to keep track of patient information. Hospitals are an essential part of the health-care system, and having a competent online hospital management system is a must in today's environment. Patients, doctors, and hospital administrators can all benefit from this Hospital Management System, which is designed to give a faster and more efficient response to their diverse demands.
1.1.1 Background of the organization
The hospital is a critical institution that plays a vital role in providing healthcare services to the community. As part of its commitment to improving patient care and enhancing operational efficiency, the hospital has initiated a project to implement a modern online hospital management system. The organizational vision is to become a world-class healthcare provider that offers patient-centered care, fosters innovation, and promotes excellence in research and education. The mission is to provide high-quality, compassionate, and accessible
Whiteboards: Hospitals used to write patient appointment information on a whiteboard, which would include the patient's name, appointment time, and doctor. The board would be updated throughout the day as appointments were added or changed. Spreadsheet: Some hospitals used spreadsheets to schedule patient appointments. The spreadsheet would include the patient's name, appointment time, and doctor, and staff would manually update the spreadsheet as needed.
Prescription management
Hospitals used to write out prescriptions by hand, which would then be filed and tracked manually. This often led to errors, such as illegible handwriting, and made it difficult to track patients' medication histories. Some of the manual patient prescription systems that hospitals used to use: Handwritten prescriptions: Hospitals used to write out prescriptions by hand, which would then be filed and tracked manually. This often led to errors, such as illegible handwriting, and made it difficult to track patients' medication histories. Medication administration record (MAR) sheets: Hospitals would keep track of patients' medications using MAR sheets, which would include the patient's name, medication name, dosage, and frequency. Staff would manually update the sheet as medications were administered. Pharmacy dispensing logs: Hospitals used to keep track of medications dispensed to patients using pharmacy dispensing logs. These logs would include the patient's name, medication name, dosage, and frequency. Pharmacy staff would manually update the log as medications were dispensed. Medication administration chart (MA chart): Some hospitals used MA charts to keep track of patients' medications. The chart would include the patient's name, medication name, dosage, and frequency. Staff would manually update the chart as medications were administered. Overall, these manual systems were often time-consuming and error-prone. The advent of modern computer-based hospital management systems is a necessary for patient registration, appointment scheduling, and prescription management for its much more efficient and accurate mechanism.
