1.7 Health Information Systems

1. Introduction

There are a variety of healthcare models, each with their own strengths and weaknesses.
Each country has its own healthcare system and models, and the model used by a country can affect the cost, access, and quality of healthcare for its citizens.

There are 4 major healthcare models.

  • The Beveridge Model.
  • Bismarck Model.
  • National Health Care Insurance.
  • Out of pocket Model.

1.1 The Beveridge Model

The Beveridge model is a type of national health system that is characterized by a publicly financed and publicly provided healthcare system. The name comes from Sir William Beveridge, a British economist and social reformer, who proposed the idea in 1942.

In a Beveridge model, healthcare is funded through general taxation, and all citizens are eligible for healthcare coverage regardless of their income or employment status. This model typically features a single payer system, where the government negotiates prices with healthcare providers and pays for all necessary medical treatment.

The Beveridge model is known for its universal coverage, cost control and simplicity. However, it can also lead to long waiting times for certain procedures, lack of financial incentives for healthcare providers, and a lack of consumer choice in healthcare services. Countries such as the United Kingdom, Spain, Italy, and Cuba are examples of countries that have a Beveridge model.

1.2 The Bismarch Model

The Bismarck model has often contrasted with the Beveridge model, it is also a type of national health system characterized by a publicly financed and provided healthcare system.The name comes from Otto von Bismarck, a 19th century German statesman, who implemented the first version of this model in Germany during the late 19th century.
In the Bismarck model, healthcare is funded through a combination of social insurance contributions and taxes. This model typically features a multi-payer system, where different groups of people, such as employees and their employers, pay into a common fund which is then used to pay for healthcare.

The Bismarck model is known for its cost containment, and efficiency by creating competition between public and private healthcare providers. It also provides financial protection for citizens and allows for more consumer choice in healthcare services. However, this model can also lead to higher administrative costs, higher healthcare costs for the elderly and low-income individuals, and a lack of universal coverage. Countries such as Germany, France, Belgium, and Japan are examples of countries that have a Bismarck model.

2.Types of Healthcare information systems

Health Information Systems (HIS) refers to the combination of information technology and management processes used to manage and share information related to the healthcare industry. This can include electronic health records (EHRs), computerized physician order entry (CPOE) systems, and other healthcare data management systems. HIS is designed to improve the efficiency and effectiveness of healthcare delivery by making information easily accessible to healthcare providers, patients, and other stakeholders.

2.1 EMR (Electronic Medical Record)

An electronic medical record (EMR) is a digital version of a patient's medical history and healthcare information. EMRs are designed to be accessed and updated by healthcare providers, such as doctors, nurses, and pharmacists, in order to support the delivery of healthcare services.
EMRs typically include a wide range of information about a patient's healthcare, including demographic data, medical history, diagnoses, treatments, medications, and test results. EMRs can also include notes and documentation from healthcare visits, such as progress notes and discharge summaries.

EMRs are typically accessed through a secure online portal, and they may be integrated with other healthcare systems, such as electronic prescribing systems and clinical decision support systems. EMRs can be used by healthcare providers to improve the efficiency and effectiveness of care delivery, as well as to support decision-making and research.
Overall, EMRs are an important tool in modern healthcare, as they allow healthcare providers to access and use patient data in real-time to support patient care and improve healthcare outcomes.

2.1.1 EHR ( Electronic Health Record)

EHR has simillarites as the EMR having an accessed secure online portal and being integrated with other healthcare systems, but it is a more comprehensive record of patient information that goes beyond the information typically found in an EMR. It includes information from all healthcare providers involved in a patient's care, including hospitals, clinics, and lab results. This allows for a more holistic view of a patient's health history, and enables better coordination of care.

2.2 Remote Patient Monitoring (RPM)

A Master Patient Index (MPI) is a database that is used to store and manage patient information in a healthcare organization. The MPI is typically used to identify patients and match them to their medical records, and it may include demographic information, such as the patient's name, date of birth, and contact information.
The main purpose of an MPI is to ensure that a patient's healthcare information is accurate, complete, and up-to-date, and to prevent errors or duplications in the patient's medical records. To achieve this, the MPI typically includes a unique identifier for each patient, such as a medical record number or a patient identification number, which is used to link together all of the patient's medical records and healthcare encounters.
MPIs are typically accessed and updated by healthcare providers, such as doctors, nurses, and pharmacists, through a secure online portal. They may be integrated with other healthcare systems, such as electronic health records (EHRs) and clinical decision support systems, in order to improve the efficiency and effectiveness of care delivery.
Overall, an MPI is an important tool in modern healthcare, as it allows healthcare providers to access and use patient data in real-time to support patient care and improve healthcare outcomes.

2.3 Clinical Decision Support (CDS)

Clinical decision support (CDS) is a healthcare technology that provides real-time guidance to healthcare providers based on the patient's medical history and current condition. CDS systems use algorithms and artificial intelligence (AI) to analyze a patient's data and provide recommendations or alerts to healthcare providers, such as doctors, nurses, and pharmacists, as they care for the patient.
CDS systems can be used to support a wide range of clinical tasks, including diagnosis, treatment planning, medication management, and disease prevention. For example, a CDS system might provide a recommendation for a particular diagnostic test based on the patient's symptoms and medical history, or it might alert a healthcare provider to a potential drug interaction based on the patient's current medications.
CDS systems are typically accessed through a secure online portal and may be integrated with other healthcare systems, such as electronic health records (EHRs) and clinical information systems. They can be used by healthcare providers to improve the efficiency and effectiveness of care delivery, as well as to support decision-making and research.
Overall, clinical decision support systems are an important tool in modern healthcare, as they allow healthcare providers to access and use data in real-time to support patient care and improve healthcare outcomes.

2.4 RPM ( Remote Patient Monitoring)- Telehealth

providers to collect and analyze data from a patient's medical devices or sensors remotely, typically through an online portal. RPM systems are designed to support ongoing patient care and monitoring, and they may be used in a variety of settings, including hospitals, clinics, and patients' homes.
RPM systems typically involve the use of sensors or devices that are placed on or worn by the patient, such as wearable fitness trackers, blood pressure monitors, or glucose monitors. These sensors or devices collect data about the patient's health and transmit it to an RPM system, which processes and analyzes the data.
Healthcare providers can access and review the data collected by an RPM system through a secure online portal, and they can use the data to monitor the patient's health and make clinical decisions. For example, a healthcare provider might use RPM data to monitor a patient's blood pressure or glucose levels over time, or to track the patient's progress after a surgical procedure.
Overall, RPM systems are an important tool in modern healthcare, as they allow healthcare providers to monitor and support patients remotely, which can improve patient outcomes and reduce the need for in-person visits.

2.5 Practice Management Software

Practice management software is a type of healthcare technology that is used to support the administration and management of a healthcare practice or organization. Practice management software typically includes a range of tools and features that are designed to streamline administrative tasks, such as scheduling appointments, managing patient records, and billing and coding.
Practice management software may be used by a variety of healthcare providers, including doctors, nurses, and other healthcare professionals, as well as by administrative staff and managers. It may be accessed through a secure online portal, and it may be integrated with other healthcare systems, such as electronic health records (EHRs) and clinical decision support systems.
Practice management software can be used to improve the efficiency and effectiveness of care delivery by automating administrative tasks and allowing healthcare providers to focus on patient care. It can also be used to support financial management and compliance, and to provide insights and analytics to help healthcare organizations make informed decisions.
Overall, practice management software is an important tool in modern healthcare, as it allows healthcare providers and organizations to streamline administrative tasks and support the delivery of high-quality care.

2.6 Patient Portals

A patient portal is a secure online platform that allows patients to access and manage their own healthcare information, as well as to communicate with their healthcare providers. Patient portals are typically accessed through a web browser or a mobile app, and they may be provided by healthcare organizations, such as hospitals, clinics, and primary care practices.
Patient portals typically include a wide range of features and tools that are designed to support patient engagement and self-management. For example, patients may be able to view their medical records, such as diagnoses, medications, and test results, through a patient portal. They may also be able to schedule appointments, request prescription refills, and communicate with their healthcare providers through the portal.
Patient portals can be an important tool in modern healthcare, as they allow patients to take an active role in their own care and to better understand and manage their health. They can also improve the efficiency and effectiveness of care delivery by reducing the need for in-person visits and enabling patients to access care remotely.

2.7 Laboratory Information Systems

Laboratory information systems (LIS) are digital systems that are used to collect, store, and analyze data from laboratory tests and procedures. LISs are typically used in hospitals, clinics, and other healthcare organizations to support the delivery of diagnostic and therapeutic services.
