Significance of Health Informatics in Healthcare System

Introduction
Informatics in the healthcare system substantially assists in controlling the health care
cost and improving the quality of healthcare interventions (Liu & Rubin, 2012). Various
informatics applications facilitate the meaningful utilization of healthcare information in the
clinical settings. Healthcare informatics in accordance with the HITECH (Health Information
Technology for Economic and Clinical Health) ACT assists in the systematic management of the
electronic health record in the medical facilities. The development of electronic health records
through informatics applications not only safeguards the protected health information but also
helps in improving the financial incentives for the credible treatment providers. A range of
informatics tools assists in the development of various decision support systems to facilitate the
process of shared decision-making in the treatment setting (Liu & Rubin, 2012). The elevated
utilization of informatics in acquiring computer-assisted diagnoses assists in improving
diagnoses precision as well as the quality of clinical interventions. Informatics substantially
assists in tracking and subsequently improving healthcare compliance of the treated patients
(Payne, et al., 2013).
Health informatics substantially reduces healthcare costs and improves healthcare utility,
thereby elevating the scope of implementation of a range of care delivery models for the eligible
patients. HITECH incentives are based on bundled payment systems for the healthcare providers
(Payne, et al., 2013). These payment systems facilitate the transfer of a single payment allowance
for each healthcare service session. This not only reduces the healthcare cost but also minimizes
the scope of redundant payment to the services providers. Health informatics effectively reduces
the cost and time invested in searching multiple entries or charts across the clinical records. The
technologies assist in education enhancement of care providers through various information
resources (Payne, et al., 2013). Health information technology (IT) assists in improving quality
metrics’ feedback and drug interaction evaluation in the clinical facility. Health IT also facilitates
the implementation and utilization of predefined dosage range, checklists, and evidence-based
order sets in the hospital settings. Health informatics applications escalate several reminders for
the execution of preventive health interventions.
Health IT-based improved clinical decision support system, alerts, reminders, and dose
range checks substantially reduce the risk of treatment errors (Payne, et al., 2013). The data

summarization and integration through health informatics helps in decreasing the risk of test
order redundancy and prescription errors. Health IT also assists in updating the knowledge of
physicians in relation to the advance directives of the treated patients. Informatics applications
prove to be the essence of healthcare business activities since they facilitate the promotion of
quality healthcare services across the consumers (Ohno-Machado, 2013). The cost-saving
acquired through informatics utilization improves the efficiency of the healthcare revenue cycle
to a considerable extent.
Informatics Applications
Four health informatics applications along with their benefits, cost, and reviews are mentioned
below (Rezaei-Hachesu, Safdari, Ghazisaeedi, & Samad-Soltani, 2017).
A. Electronic Health Card (EHC)
1. EHC improves the process of medical decision-making through patient
involvement.
2. EHD facilitates medical tourism.
3. Insurance details and privilege on the card help in acquiring treatment across
the approved locations.
4. EHC helps in prescription management.
5. The clinical and drug information retrieved through EHC assists in maintaining
the disease diary.
6. EHC is provided free of cost by the NHS business service authority.
7. Users indeed appreciate the application of EHC on an international scale.
B. Telemedicine
1. Telemedicine assists in the process of remote patient monitoring.
2. Telemedicine has wide applications in medical tourism.
3. Telemedicine facilitates the promotion of healthcare services on an international
scale.
4. Teleconsultation provides the best treatment options for the travelers.
5. Telemedicine saves healthcare cost to a substantial extent.
6. Each teleconsultation costs about $40-$50 for the treated patients (AJMC, 2016).

7. Healthcare users find telemedicine as an innovative and convenient intervention
for handling their treatment/consultation issues.
C. Electronic Health Record (EHR)
1. EHR assists in safeguarding the protected health information.
2. EHR helps the patients to view their medical records as per convenience.
3. EHR facilitates the precision in medical decision-making.
4. EHR reduces the scope of medication errors.
5. EHR facilitates the rectification of inappropriately incorporated healthcare
information.
6. EHR implementation cost attributes to $85, 0000 along with the maintenance
cost of $85000 for medical facilities (USDHHS, 2011).
7. Healthcare users advocate the use of EHR in medical units.
D. Wireless Mobile Healthcare Application (WMHA)
1. WMHA assists in enhancing the healthcare knowledge of patients.
2. WMHA extends wide applications in healthcare sensor networks.
3. WMHA assists in protecting e-health data.
4. WMHA facilitates a range of machine learning applications.
5. WMHA is also utilized in wearable medical equipment.
6. Most mobile apps are available free of cost for the users (Ventola, 2014).
7. Users consider WMHA as a useful application related to their healthcare
management.
E. Imaging Informatics
1. Imaging informatics extends applications in radiology order entry system.
2. Imaging informatics is utilized in radiology decision support systems.
3. Imaging informatics is used in the post-processing of the retrieved images.
4. Imaging informatics is used in developing the structured reporting system in the
radiology department (Mendelson & Rubin, 2014).
5. Imaging informatics is utilized in regulatory reporting and data mining.
