Health Information Concepts and Purposes
Data, Information, Knowledge:
Data: raw facts and figures with no meaning. Example from the chapter: a monthly discharge figure (e.g., 560 patients last month).
Information: data that have been turned into meaning that supports understanding and decision making.
Knowledge: the information and experience that give power to make informed decisions.
Distinctions are important to understand how the health record is used.
Example given: Hospital A discharged 560 patients last month, up 10 percent; while data is a raw count, information includes trends and interpretations.
Mathematical framing: the relationships among data, information, and knowledge can be viewed as transforming data to information to knowledge, often through analysis and interpretation.

Purposes of the Health Record
The uses of the health record are divided into primary and secondary purposes.
Primary purposes: directly related to patient care and the day-to-day operations of the healthcare organization.
Secondary purposes: uses not directly related to patient care but essential for the healthcare system, regulation, education, and research.
Primary Purposes (related to patient care and administration)
Patient care: Documentation of care provided by physicians, nurses, and allied health professionals (including physical therapists and dietitians). The documentation serves as a communication tool and may include treatments and the patient’s response to treatment. Medical scribes may document on behalf of physicians to save time.
Management of patient care: Used to develop patient care standards, conduct research at local/state/national levels, and evaluate quality of care.
Administrative purposes: Billing for services, budgeting, scheduling, staffing, and strategic decisions about the organization.
Secondary Purposes (not directly about patient care but essential)
Education of healthcare professionals: Used to teach current and future providers how to document care and manage health information.
Legal, accreditation, and policy development: Protects the organization from malpractice claims, monitors compliance with laws/regulations, and supports accreditation standards. Data from health records inform national funding decisions and healthcare direction.
Public health and research: Data are aggregated to inform best practices, drug efficacy, new treatments, and to study outcomes. Local health departments use information to identify outbreaks early and manage epidemics.
Formats of the Health Record (overview introduced here; more detail later)
Paper health record: Traditional paper-based documentation.
Electronic Health Record (EHR): A digital record that conforms to interoperability standards and can be created, managed, and consulted by authorized clinicians across more than one organization.
Hybrid health record: A combination of paper and electronic records where some documents are stored on paper and others in the EHR.
Page 3
Users of the Health Record
Healthcare providers are the primary users, but many others use health record data to manage the organization and the industry.
Aggregate data: Data extracted from individual records and combined into deidentified information about groups of patients. Used for analysis and research (e.g., cancer survival rates, drug safety).
Deidentification: Removal of all data elements that could identify a patient.
Individual Users
Patient care providers: Physicians, nurses, and allied health professionals rely on health record information to make care decisions and document care. Allied health professionals include respiratory therapists, nutritionists, physical therapists, etc. Patient care managers evaluate services and look for patterns to improve outcomes and efficiency; support staff gather information for managers.
Coding and billing staff: Use documentation in the health record as the basis for reimbursement. They read the entire health record to assign diagnoses and procedures; billing submits codes to the insurer.
Patients: Informed consumers can access their health records via copies, patient portals, or personal health records (PHRs).
Employers: May use records for health insurance claims processing, wellness programs, work return-to-work determinations, and disability claims support.
Lawyers: May access health information for life insurance claims or lawsuits; patient consent is required.
Law enforcement: May access documentation to investigate injuries/crimes and support security.
Healthcare researchers: Use records to study drug safety/efficacy and care value; deidentified aggregate data are used for research.
Government policymakers: Use data from claims to develop and evaluate laws, regulations, and standards.
Institutional Users
Third-party payers: Reimbursement entities (commercial insurers, managed care, government programs, accountable care organizations, self-insured employers) use health records to validate care and justify reimbursement.
Medical review organizations: Evaluate quality and appropriateness of care; determine medical necessity.
Research organizations: Conduct medical research, cancer registries, transplant registries, etc.
Educational organizations: Train healthcare professionals using health records as case studies.
Accreditation organizations: Establish standards that require review of health records to ensure compliance (e.g., H&P within 24 hours of admission).
Government licensing agencies: Review records to ensure licensing compliance and eligibility for federal funding.
Policymaking bodies: Use healthcare claims data for decision-making related to programs (e.g., CMS uses data to revise reimbursement systems).

Overview of HIM Functions
The HIM department performs multiple functions to support patient care and the organization. Responsibilities focus on quality, security, and availability of the health record.
Functions can be performed within HIM, in other departments, or outsourced. Outsourcing means engaging an external party to perform a function onsite or offsite.
Typical HIM functions include:
Medical editors
Disclosure of health information
Clinical coding and reimbursement
Record storage and retrieval (paper and electronic)
Statistics and research compilation
Master patient index (MPI) maintenance
Record processing
Management and use of registries (e.g., cancer, trauma, birth defects)
Birth and death certificate completion
The HIM department collaborates with other departments (patient care, information governance, quality management, billing, and patient registration).
Medical Transcription and Voice Recognition
Medical transcription involves deciphering and typing dictated medical reports. It may be inside the HIM department, a separate centralized unit, or outsourced.
Liaisons coordinate between physicians and transcription services, monitor turnaround times and quality, and ensure dictation dates are recorded.
Turnaround times vary by document (e.g., radiology reports within 24 hours; discharge summaries within 3 days).
Voice recognition (speech recognition) is increasingly used:
Front-end: physicians edit and sign immediately after dictation.
Back-end: transcriptionists edit after dictation; signing occurs later.
Artificial intelligence (AI) may be used to assemble summaries from health record data (high-level information tech that imitates learning and reasoning).
Natural Language Processing (NLP): Converts human language (structured or unstructured) into data usable by computer systems; NLP underpins speech recognition.
Disclosure of Health Information
HIM handles requests to disclose patient-identifiable information to others for patient care, insurance, legal claims, or other purposes.
Disclosure can be internal or outsourced to a disclosure company.
The Disclosure of Health Information supervisor ensures policy adherence, timely processing, and productivity.
Quality control aims to ensure health records are available for patient care and that only the requested documents are released.
During transition to EHR, identifying the legal health record is challenging; the process may involve a document management system (DMS) to digitize and route disclosures.
HIPAA requires an accounting of disclosures across the organization, including what was released, to whom, and when.
Clinical Coding and Reimbursement
Clinical coding assigns codes to diagnoses and procedures. Coding systems can vary by organization and encounter.
Abstracting: Extracting information from documents to create a summary (or entering data from source documents into a system).
The coding system supports billing and reimbursement; delays in coding delay reimbursement.
The coding supervisor ensures code quality and timely coding; CAC (computer-assisted coding) uses EHR data to assign codes and the HIM professional monitors quality rather than coding manually.
Record Storage and Retrieval (Paper vs Electronic)
Transition to EHR is gradual and often hybrid for years; paper records still require management until fully migrated.
The EHR stores health information electronically with audit trails to track access and changes.
Digital workflows and indexing support rapid retrieval; some documents are scanned and indexed into the EHR.
Master Patient Index (MPI) and EMPI
MPI: Permanent record of all patients treated at an organization; used to look up demographics, dates of care, health record numbers, etc.
Demographics (demographic data) include: name, address, date of birth, insurance information, etc.
EMPI (Enterprise MPI): Links patient information across multiple facilities in an enterprise (e.g., hospital and clinics).
EMPI elements include: internal patient ID, name, date of birth, gender, race, ethnicity, address, phone, alias/maiden names, SSN, facility ID, universal patient identifier, account/visit number, admission/encounter data, discharge date, encounter type, primary physician, patient disposition.
Common MPI quality problems: overlays (wrong patient record number assigned to a record), duplicates (two numbers for the same patient), and overlaps (one patient across multiple records in different locations).
Data quality issues: typographical errors, outdated demographic information, etc. Clean-up uses three matching algorithms:
Deterministic algorithm: requires exact or near-exact matches on data elements (e.g., name, date of birth, SSN).
Probabilistic algorithm: assigns weights and uses statistics to estimate the likelihood that two records belong to the same patient.
Hybrid algorithm: combines deterministic and probabilistic approaches.
Continuous MPI quality management requires processes to prevent/identify duplicates, educate staff about MPI impact, and notify department managers when issues are detected.
Paper Health Records, Microfilm, and Image-Based Storage
Paper records require storage space; microfilm, microfiche, jacket microfilm, and off-site storage are traditional methods to reduce space.
Microfilm formats:
Roll microfilm: images stored on a long roll; retrieval can be difficult if a patient has multiple encounters stored on different sections.
Jacket microfilm: images stored in jackets (one jacket per page or set, grouped to maintain unit records).
Microfiche: a flat, jacket-sized form of microfilm; used to share with care units without exposing originals.
Image-based storage (scanned documents): documents are indexed (by patient, document type, etc.) and stored as image files (e.g., .tif, .jpg). Images are quick to retrieve when indexed, but the image itself is not text-searchable unless indexed data is used.
During transition periods, both paper and electronic elements may exist; organizations implement policies to handle off-site storage, privacy, and security.

Page 9
Record Formats and Access in the Electronic Environment
In the electronic environment, the health record is managed by the EHR: an electronic record conforming to interoperability standards and accessible across organizations.
Record filing and tracking of EHRs: The need for physical filing is reduced or eliminated; the EHR tracks access via audit trails and supports indexing and workflow.
Record completion in EHRs is handled by the information system to ensure clinical professionals can access and complete records efficiently.
Indexing links patient name, health record number, and other identifiers to the scanned document; electronic work queues route records to professionals with deficiencies to complete/verify.
The EHR minimizes deficiencies by prompting for missing documents and ensuring authentication of notes and sign-offs.
Workflows and data sharing: The work queue can route records to HIM for coding/abstracting or to other departments; the document management system (DMS) enables cross-department workflow and electronic routing.
Version control: The EHR may contain multiple versions of the same document (e.g., signed vs unsigned). Policies determine which versions are available; reconciliations ensure the correct version is accessible for a given time period.
Management of free-text data: Free-text (unstructured) data are unbounded and less searchable; structured data are preferred to improve retrieval. Free-text data include narrative notes, emails, voicemail, audio, images, video; NLP helps convert free text into usable data.
Management and integration of digital dictation, transcription, and voice recognition:
Digital dictation: Physician dictation captured digitally; transcriptionists can edit or translate to text.
Front-end speech recognition: Physician edits in real time and signs quickly.
Back-end speech recognition: Transcriptionists edit after dictation; signing is delayed; improves physician focus on patient care.
Handling materials from other organizations: Non-EHR documents are scanned and indexed; electronic documents or digital images can be imported into the EHR; policies vary by state law and must be consulted with counsel.
Reconciliation processes: Ensures all health records are received in HIM; reconciling paper and electronic elements during transition.
Data mining in EHRS: The EHR enables data mining to extract and analyze large datasets to identify patterns and relationships for improving care.
Page 10
Amendments, Corrections, and Documentation Integrity in the EHR
Amendments and corrections: If a document needs amendment, it is unlocked, edited, and a new version is created. The original version remains, and the identity of the person making changes and the time of the change are recorded.
If the amendment affects data transferred to other systems, updates must propagate to those systems as well.
The EHR should maintain traceability to determine who made changes and when; the system should preserve historical versions to support accountability.
Reconciliation and integrity require careful management of changes across related information systems to maintain data consistency.
Quality Control and Data Entry in EHRS
Data are collected via several mechanisms: scanning, data entry, barcodes, and data transfer from other systems.
Input controls to improve data quality include:
Input masks (e.g., SSN format 000-00-0000)
Drop-down menus for predefined choices (e.g., states)
Checkboxes for yes/no,
Radio buttons for single selections.
Best practices in screen design to improve data quality:
Clear navigation and labeling
Consistent button placement and screen layout
Alerts for potential errors and guidance/references
Validation features to ensure required fields are completed and data types are correct
User-friendly input designs to reduce keystrokes and errors
Confirmations for critical actions (e.g., deleting a file)
Identification of required fields
Data validation categories:
Completeness: Are all required fields entered?
Format: Is the data of the correct type (numeric/alphabetic)?
Range: Are numeric values within acceptable ranges?
Consistency: Do data combinations make sense?
Database checks: Compare against a database to ensure correctness.
Output design considerations
Minimize clicks to reach data
Consolidate data into a single, organized menu to reduce screen layers
Data Management and Workflows in EHRS
The EHR supports a seamless workflow with reduced sequential dependencies (via DMS) so that multiple tasks can occur in parallel without waiting for one another (e.g., coding can begin before all documents are analyzed).
Version control and reconciliation help ensure that users access the correct version of documents during the care process.
Page 11
Identification Systems and Filing Approaches
Identification systems link the patient to the health record; the health record number is a key element in the MPI and is a unique identifier issued at the first encounter for all subsequent encounters.
The SSN should not be used as the primary health record identifier due to confidentiality concerns.
Paper-based identification systems include numeric, alphabetic, and alphanumeric approaches. In the EHR, multiple identifiers (health record number, patient name, etc.) support retrieval.
Common paper filing systems:
Serial numbering system: A unique numeric identifier for every encounter; a patient can have multiple health record numbers if repeatedly admitted; this is inefficient and costly as records are spread across multiple files.
Unit numbering system: A single “unit” identifier used across encounters for a patient within a healthcare system; more scalable for large organizations.
Alphabetic filing system: Filing by last name; used in small clinics; can lead to ambiguity when multiple patients share the same name even with middle initials.
Electronic Health Records (EHR) and Identifiers
In the EHR, identifiers include health record number, patient name, and patient account number (unique to an episode of care) to retrieve data.
The unit numbering system is the most common in the EHR context due to its scalability and usability across encounters.
Patient account number: A billing-centric identifier assigned for each episode of care; helps tie records to a billing event.
Paper Health Record Filing Systems in Detail
Serial numbering: Each encounter gets a new health record number; requires retrieving multiple records to view a single patient’s complete history; high inefficiency and cost.
Alphabetic filing: File by last name; limited by name duplication; may require cross-referencing.
Unit numbering: Preferred for large organizations; reduces duplicates and promotes efficient retrieval.
Summary of Identification Approaches
Paper: Serial, unit, alphabetic systems.
Electronic: Health record number, patient name, account number, and other identifiers enable efficient retrieval and cross-organization sharing.
Statistics and Registries
Statistics: A branch of mathematics used to collect, organize, summarize, and analyze data (historically focusing on admissions, discharges, length of stay).
With EHR, organizations can generate a wider range of analyses and comparisons.
Registries: Databases dedicated to specific diseases or conditions (e.g., cancer registry, trauma registry, birth defects registry) to collect data for research, patient care, and quality monitoring.
Birth and Death Certificates and Other Registries
Birth data: birth information, pregnancy data, parents, etc.
Death data: time of death, cause of death, etc.
HIM Interdepartmental Relationships
HIM cannot operate in isolation; requires collaboration with:
Patient registration: Captures patient demographics and ensures MPI quality; reconciles duplicates.
Billing/PFS: Relies on coding and data abstraction for reimbursement.
Patient care departments: Nursing units, emergency department, etc., to ensure accessibility of records from prior encounters.
Information systems: Ongoing collaboration for planning, implementing, and maintaining systems impacting the health record.
Quality management: Uses records for committee meetings, audits, outcomes; HIM supports data collection and reporting.
Virtual HIM
Much work can be performed remotely due to EHR implementation; centralized HIM services are common.
Remote functions include coding and transcription; managers ensure productivity and independent work.
HIM staff interfaces with patient care, information systems, and quality management to ensure data integrity.
Page 12
HIM Information Systems and Core Functions
HIM relies on information systems to support health record processing, access, and sharing.
Core HIM information systems include:
Disclosure of health information systems (requests, tracking, and processing)
Coding systems (encoders, groupers, CAC)
Registries (cancer, birth defects, transplant, etc.)
Billing systems (coding data flow to billing)
Quality improvement systems (data repositories for monitoring trends, statistics, outcomes)
EHRs: The central repository delivering patient information across the enterprise; CDI/CDS features and interoperability standards.
EHRs contain CDS (Clinical Decision Support) that provides alerts and reminders about allergies, due tests, immunizations, etc. Benefits include reduced administrative costs and improved care quality, with better accessibility to information.
Personal Health Records (PHR): An electronic or paper health record maintained by an individual for themselves or someone in their care. It is a subset of information available to and controlled by the patient; not the same as an EHR, but a patient-involved tool (e.g., medication lists, self-monitored data).
PHRs may be provided by the healthcare organization or purchased/subscribed from a vendor.
EHR Components and Data Capture
The EHR uses multiple source systems to capture patient information: demographic data, test results, dictated reports, etc.
CDS features include alerts for allergies, tests due, immunizations, and reminders.
The EHR’s advantages include improved access to information and reduced administrative overhead; it enhances data-driven decision-making.
Personal Health Records in Practice
PHRs empower patient engagement and chronic disease management by offering a place to consolidate and share health data.
PHR data are controlled by the patient, whereas EHR data are controlled by the healthcare organization.
Page 13
HIM Roles and Interdepartmental Collaboration
HIM professionals take on various roles, including management (director, assistant director, supervisors) and domain experts in health information management, storage, and processing.
HIM interacts with multiple departments to support their needs and ensure the integrity and accessibility of health information.
Real-World Case 3.1: Riverview Medical Center’s transition from one EHR to another; the top admitting physician pushes for copy-and-paste to speed documentation and revenue generation. The HIM director resists, citing policy and data integrity concerns. The EHR consolidation and MPI transition are ongoing, requiring careful policy enforcement.
Real-World Case 3.2: Medical System of America purchases three hospitals and plans to consolidate HIM, billing, and information systems, including MPI integration; the EMPI database is prepared for this consolidation.
Auditing and Quality Assurance
Auditing is the on-site verification of processes to ensure compliance with requirements.
Internal audits are conducted by the organization; external audits are conducted by consultants or outside entities.
Quality standards: Example, tumor registrars should maintain a 98% quality rate in data abstraction; findings drive training and improvements.
Check Your Understanding 3.2 (highlights of audit-focused questions)
What type of health record is controlled by patients? Personal health record (PHR)
How are amendments to the EHR handled? The amendment must have a separate signature, date, and time; changes are tracked with an audit trail.
Version control requires what? Policies to control which version(s) are displayed; maintain all versions.
Why might an organization justify not allowing copy-and-paste? Risks include copying outdated information or introducing inaccuracies; governance concerns about authorship.
What enables a formatted numeric input like 10101963 appearing as 10/10/1963? Input mask
What kind of audits are performed by healthcare organization staff? Internal audits
True statement about disclosure information systems? All disclosures should be recorded regardless of where released.
The HIM department’s relationship with other departments? HIM works with a wide range of departments.
Which paper filing system is inefficient? Serial (and possibly serial-unit as a combined inefficiency)
In screen design, checking data format falls under? Data validation

HIM Roles, Real-World Scenarios, and EHR/PHR Relationships
Summary of HIM roles: management positions and subject-matter experts in HIM functions across the health information lifecycle.
Real-World Case 3.1 (copy-paste policy): Demonstrates organizational policy balance between physician productivity and data integrity. Often, remote HIM operations influence decisions about EHR usability and data governance.
Real-World Case 3.2 (system consolidation): Highlights the need for MPI/EMPI alignment and interdepartmental collaboration during mergers or acquisitions.
The case studies emphasize practical challenges in data governance during transition periods and the importance of policy consistency across the enterprise.
Auditing and Quality Measures
Internal audits monitor quality and compliance within the organization; external audits validate these findings.
Quality metrics should be tracked by different dimensions (e.g., by registrar, by cancer type) to identify training needs and performance gaps.
