IT Applications in Health Care Technology: Key Standards for Productivity, Security, and Scalability

Ensuring digital innovation in health care demands strict adherence to global standards. Today’s medical environments increasingly rely on information technology—ranging from digital patient records to AI-assisted diagnosis and pharmaceutical tracking. To guarantee reliable, secure, and inclusive IT applications, four influential international standards provide systematic guidelines for health care technology. These standards underpin greater security, enhanced productivity, and scalability, helping businesses meet regulatory requirements while future-proofing their digital strategies.

Overview / Introduction

Health care has transformed with the rise of digital technologies. Electronic health records, advanced imaging, data interoperability, and regulated pharmaceutical management are now intrinsic parts of efficient, modern medicine. While these advancements promise improved care and operational efficiency, they also introduce complexities: data privacy, accessibility, interoperability, and rigorous quality control are essential.

International standards in information technology for health care ensure that new solutions are safe, usable, reliable, and compliant with worldwide best practices. Organizations that align with these guidelines benefit from reduced regulatory risk, increased operational productivity, and scalable IT architectures. This comprehensive guide explores four critically important standards:

• ISO/IEC 29138-4:2026: User interface accessibility
• ISO/TR 24936:2026: Endoscopic video and clinical information
• ISO/TS 20451:2026: Identification of medicinal products (data elements and structures)
• ISO/TS 21405:2026: Methodology for developing IDMP ontology

You’ll learn what each standard covers, practical implications, and why adopting these frameworks is now a must for every organization building, deploying, or managing IT in health care.

Detailed Standards Coverage

ISO/IEC 29138-4:2026 - Enhancing User Interface Accessibility

Information technology — User interface accessibility — Part 4: Applying user accessibility needs

This standard provides guidance on systematically applying user accessibility needs (UANs) to the procurement, development, and evaluation of information and communication technology (ICT) products and services. As technology becomes central to health care, IT systems must be universally accessible, especially to those with disabilities or unique needs. ISO/IEC 29138-4 guides organizations in:

• Identifying diverse user groups
• Specifying relevant user goals and tasks
• Translating these needs into explicit design and development requirements
• Ensuring accessibility requirements are defined, met, and evaluated across the product lifecycle

By contextualizing user accessibility needs, organizations make sure their ICT systems are inclusive, future-proof, and compliant. This process covers documenting solutions, customizing accessibility for different contexts, and reporting the rationale for how needs are met or adapted.

Key highlights:

• Systematic approach to mapping user needs to accessible ICT solutions
• Guides integration of accessibility into procurement, development, maintenance, and evaluation
• Aligns with global usability and accessibility principles for maximum inclusivity

ISO/TR 24936:2026 - Managing Endoscopic Video and Clinical Information

Health informatics — Endoscopic video and related clinical information

Laparoscopies and endoscopies are essential procedures, routinely generating hours of clinical video data. ISO/TR 24936:2026 provides a comprehensive data structure for managing video files and associated clinical metadata from these devices. Its focus includes:

• Standardized data points for video and recording devices
• Integration of case report form (CRF) data: patient details, procedures, complications, device info, and more
• Interoperability with existing health informatics standards (e.g., DICOM, FHIR, EHR systems)
• Recommendations for evidence retention, clinical training, device R&D, and privacy compliance

The standard supports seamless sharing, storage, and utilization of video and metadata, crucial for training, regulatory reporting, and research in modern health care.

Key highlights:

• Defines minimum consistent metadata for video files
• Supports diverse use cases: clinical record-keeping, device R&D, machine learning
• Ensures compatibility with global health data standards

ISO/TS 20451:2026 - Unique Identification of Medicinal Products

Health informatics — Identification of medicinal products — Implementation for ISO 11616 data elements and structures for the unique identification and exchange of regulated pharmaceutical product information

With the complexity of the pharmaceutical landscape, reliably identifying pharmaceutical products is a global priority. ISO/TS 20451:2026 details the model and technical requirements for associating pharmaceutical products with pharmaceutical product identifiers (PhPIDs), based on ISO 11616. This technical specification supports:

• Structuring and transmitting regulated medicinal product data between authorities and manufacturers
• Establishing consistent data elements for active substances, strengths, dose forms, devices, reference strengths, and confidentiality indicators
• Connecting national and international reporting using standardized terminologies and HL7 (Health Level Seven) messaging
• Enabling rapid, accurate tracking, recall management, and regulatory submissions

Built on the global IDMP (Identification of Medicinal Products) foundation, this standard is essential for regulatory authorities, pharmaceutical companies, and health care IT integrators.

Key highlights:

• Facilitates unambiguous identification and tracking of medicines globally
• Integrates with HL7, FHIR, and other medical informatics frameworks
• Supports compliance with regional and cross-border pharmaceutical regulations

ISO/TS 21405:2026 - Methodology and Framework for IDMP Ontology

Health informatics — Identification of medicinal products — Methodology and framework for the development and representation of IDMP ontology

True interoperability in health care IT is only possible when semantic meaning is preserved across systems. ISO/TS 21405:2026 introduces a methodological framework for developing an ontology—an explicit, formal specification of medicinal product knowledge anchored in the full suite of IDMP standards.

This ontology framework enables:

• Deep semantic interoperability based on FAIR data principles (Findable, Accessible, Interoperable, Reusable)
• Governance structures for collaborative, cross-jurisdictional development
• Scalable modeling of substances, dose forms, regulatory statuses, clinical indications, and more
• Continuous feedback and alignment with regional legislation, regulatory bodies, and evolving data models

Organizations implementing this framework can future-proof their health informatics by providing machine-understandable data connections, greatly improving data exchange, regulatory reporting, and automated reasoning.

Key highlights:

• Establishes best practices for semantic data modeling in pharmaceutical IT
• Promotes cross-border consistency and supports agile regulatory adaptation
• Complements the complete collection of ISO IDMP standards for medicinal product interoperability

Industry Impact & Compliance

These four standards are critical for any health care or life sciences organization deploying digital technologies. Their adoption is now a must, driven by:

• Regulatory Expectations: Health agencies and regulators increasingly expect IT solutions, devices, and software to be accessible, interoperable, and secure. Non-compliance can lead to legal penalties and reputational risk.
• Security and Privacy: With sensitive health data at stake, standards provide frameworks to minimize cybersecurity risk and protect patient data.
• Scalability and Productivity: Standardization simplifies integration across platforms, reduces duplication, and accelerates deployment of new solutions.
• International Collaboration: For organizations operating globally, harmonized standards make cross-border operations, partnerships, and regulatory submissions seamless.

Benefits of Compliance:

• Improved patient outcomes and user satisfaction
• Reduced support and rework costs
• Demonstrable due diligence in data security and privacy
• Easier scaling and integration of new digital health solutions

Risks of Non-Compliance:

• Legal and regulatory penalties
• Technology lock-in or legacy system incompatibility
• Loss of market access or partnership opportunities
• Reduced competitiveness versus compliant peers
