Study Notes
Medical Informatics Basics
- Medical informatics is a field encompassing electronic medical records, telemedicine, information retrieval, image processing, analysis, bioinformatics, and evaluation methodologies.
- Outcomes research studies the effectiveness of healthcare using large datasets and advanced technologies.
- Medical informatics focuses on healthcare, including electronic medical records, information retrieval, medical decision-making, telemedicine, clinician information needs, artificial intelligence, and outcomes research.
Islands of Information in Hospitals
- Medical history
- Order processing
- Blood bank
- Lab tests
- Pharmacy
- Admissions, discharges, transfers (ADT)
- Vital signs
- Transplant units
- Physical therapy
- Dietary
- Intensive care units (ICUs)
- Radiology, cardiology, nuclear medicine
- Outpatient clinics
- Surgery
- Billing (insurance, HMO, government)
- Scheduling (residents, rooms, equipment)
- Research support
Best of Breed Approach
- Each functional area (department or lab) prefers its own dedicated system.
- For example, SunQuest for lab testing and MediPac for ADT.
- This approach creates systems that are not easily interoperable.
- IT departments need to integrate data from different systems.
Integrated Medical Information
- Patient medical records should contain all relevant medical data.
- Patient medical records should be accessible to healthcare workers anywhere, anytime.
- Data must be digitized.
- A multimedia-capable database is needed.
Integrated Medical Information (Continued)
- Access should be limited to the data needed by the healthcare worker.
- Systems need to correlate data from various sources (e.g., symptoms, tests, diagnoses, family history).
- Data should be presented in a format that is understandable by healthcare workers.
- Healthcare worker needs should be prioritized over particular functions or departments.
- Patient privacy must be protected.
- Patients should be able to carry their medical records.
Medical Archive (Data Mining Source)
- Medical records feed into a medical archive database.
- The archive database is used for medical research.
- The database uses information retrieval, artificial intelligence, medical diagnosis support, and survival intelligence.
Medical Archive Record System (MARS)
- The University of Pittsburgh Medical Center's MARS system collects data from all departments.
- Image data is stored in separate databases.
- Each department tags its data elements.
- MARS provides metadata describing the data from each source.
MARS (Continued)
- Data storage is in text format for flexibility in searching.
- All patient data is accessible at all times.
- MARS acts as a data warehouse for research.
- Images (e.g., X-rays, sonograms) are stored and referenced.
- Full text of reports are maintained.
To Do List
- A feature to track tasks and status.
- Reduce prescription refill time by using pre-built prescription codes or previous prescriptions.
- Track patient history.
- Document patient encounters with pre-built templates and codes.
- Reduce record search time.
- Import patient pictures into charts.
- Ancillary reports storage.
- Customize patient information reports.
Phone Message Section
- The section is used to record encounters that aren't in the clinic.
- The tabulatory format allows for easy record review of vital signs.
- The system provides instant charting for time-relevant data.
- ASCII or RTF formatted reports can be imported into the chart.
- Track all relevant demographics.
- Documentation templates.
Patient Education Handouts
- Ensure patient handouts provide needed information.
- Pre-built codes speed data entry.
- Voice recognition software reduces typing effort.
Critical Design Factors
- Unique patient identifiers never change.
- Unique identifiers for every healthcare worker.
- Unique identifiers for every product (e.g., blood products, X-rays).
- Unique identifiers for every service (e.g., transfusions, physical therapy).
AI in Medical Informatics
- Problem-knowledge couplers collect patient information about a medical condition and link it to a knowledge database to produce recommendations based on medical findings.
Medical Couplers
- Screening couplers (e.g., wellness, physical examination, medical history) discover medical problems.
- Diagnostic couplers (e.g., chest pain, knee problems) determine medical problem causes.
- Management couplers (e.g., asthma, hypertension, diabetes) manage known medical problems.
Telemedicine
- Home telemedicine manages diabetes in elderly patients in medically underserved areas.
- Informatics research includes logistics, user interfaces, patient education, security, and videoconferencing.
Discovering Knowledge
- Machine learning and visualization are methods for knowledge discovery in large databases.
- Research focuses on improving existing discovery methods for clinical data.
- Important issues include training set size, data accuracy, data completeness, and data representation.
Patient Access to Medical Records
- Patient access to medical records is expected due to federal regulations.
- Little is known about patient comprehension or how access will impact the patient-caregiver relationship.
Reducing Medical Errors
- Two common causes of medical errors: inadequate access to information and ineffective communication.
- Reduce errors by linking patient data to online resources, using virtual whiteboards for coordination, and deploying on wireless handheld platforms.
Medical Decision Making
- Nurses use different problem-structuring and knowledge-structuring principles than physicians for medical decision-making, according to a University of Utah study.
Nursing Informatics
- Data and information are symbolic representations of nursing phenomena.
- Expertise in problem structuring is specific to nursing.
- Algorithms and heuristics for nursing domain problems are specific to the field.
Critical Design Factors (Continued)
- Interfaces need to be tailored to healthcare personnel (e.g., physicians, nurses, pharmacists, radiologists, lab techs).
- Minimize keying errors by using scanning technologies (e.g., bar codes, optical character recognition).
- Date and time should be stamped on every data entry.
Critical Design Factors (Continued)
- Support for multimedia data objects (e.g., X-rays, sonograms, strip charts, voice, numeric results, text).
- Support for automated and manual indexing of optical and voice data.
- Support for searching across medical records and finding patterns.
Critical Design Factors (Continued)
- Drug interaction verification.
- High-speed access and presentation.
- Remote and mobile archive and ICU monitoring data access.
- Utilize colors for test results (safe/negative – green, caution/borderline – yellow, positive/danger – red).
Critical Design Factors (Continued)
- Standardized statistical analysis (BMDP).
- Graphing capabilities.
- Report writing templates from medical test results (converting phrases to paragraphs).
- Text-to-voice and voice-to-voice telephone systems.
Critical Design Factors (Continued)
- Visualization techniques for large datasets.
- Online help for every data element (units, conversions, etc.).
- Data tracking for security, privacy, and utilization purposes.
