- Rapidly increasing focus on the improvement of interoperability and compatibility within and between systems to allow for efficient data sharing.
Core Principles and Standards in Medical Informatics
Certain principles and standards basic to medical informatics have to be maintained if optimal output is to be realized. Such include the following:
- Interoperability:The ability of several systems and units to work in synchronization in transmitting and utilizing information of health care level status.
- Data Standards:Use of programs with preset parameters for the input and retention of the information which always guarantees uniformity. Some of these are HL7, ICD-10, and SNOMED CT.
- Usability:
Systems should be designed always considering the end-users and therefore they should try to reduce the amount of time needed for the users to learn the system as well as avoid errors in the process.
- Security of Information and Privacy Policies:Protecting patient information from unauthorized access and/or breach.
- Evidence-Based Practice:Making available all the best evidence that is available from the clinical research to be utilized for making decisions.
Applications of Biomedical Informatics
1. Improving Clinical Practice:
Clarity of documents patient record and decision support systems (CDSS) position both practitioners with timely access to their patients’ health record and health-related microbes to avoid and prescribe guidelines based on provided evidence. Also, there are automated reminders about harmful side effects due to medication, and the availability of critical results of laboratory tests. Moreover, clinical pathways and clinical documentation systems improve workflow and decrease the volume of paperwork.
2. Assisting with Monitoring of Diseases:
Medical informatics allows the tracking of disease epidemic and public health phenomena. The BioSense system managed by the CDC is capable of gathering information in hospitals’ emergency departments all over the country to identify new threats to public health as they emerge and respond to them.
3. Product Development and Research:
The existence of crunched circumstantial data (Big Data) has allowed researchers, to discover new insights and relationships regarding illnesses, effectiveness of treatment rendered, and outcomes of patients encountered. The area of medical-informatics called bioinformatics uses information technology and biology to push the frontiers of genetic and targeted therapy.
4. Telemedicine:
Telehealth platforms allow patients to interact with healthcare providers via video, wearable devices, and mHealth apps. This is especially helpful to patients living at rural and less developed regions as well as during outbreaks of diseases such as COVID-19.
5. Population Health Management:
Tools in health informatics utilize the data of the population to find out which group is at risk and help to prevent the disease through, tracking the health of that group, and finding out interventions that will help. Analyzing data trends can also tell what kinds of health issues that the population might have in the future helping with planning and policies.
6. Patient Empowerment.
Mobile smartphone health applications and personal health records take the part of the patients in their health management. This includes the ability to schedule appointments, take medications and have the lab results enhance the level of patience satisfaction.
