Security Risk Assessment Guide for Thrombectomy-Capable Stroke Programs

What should a security risk assessment cover in a thrombectomy-capable stroke program?

A security risk assessment should examine how the stroke program protects information and maintains safe, timely care. Consider the confidentiality, integrity, and availability of electronic protected health information (ePHI), as well as the potential effect of a disruption on clinical operations. Under HIPAA, covered entities and business associates must conduct an accurate and thorough risk analysis and manage identified risks to a reasonable and appropriate level. See 45 CFR § 164.308.

Set the assessment’s boundaries around the full care pathway, not just the procedure room or the hospital’s central IT network. Include the people, processes, systems, devices, locations, vendors, and data exchanges that support stroke response and thrombectomy care.

• Information risks: Identify where PHI is created, viewed, stored, changed, and shared, and assess the safeguards that protect it.
• Care-continuity risks: Consider how loss of access to records, imaging, communications, or equipment could affect clinical decisions and coordinated care.
• Security risks: Examine threats such as unauthorized access, misdirected information, malware, device vulnerabilities, equipment theft, utility outages, and mistakes during routine work.
• Existing protections: Review safeguards, determine whether they are implemented and working as intended, and document gaps.
• Risk priorities: Record the threat, vulnerability, likelihood, potential impact, current protections, and planned response for each significant risk.

HIPAA risk analysis should cover ePHI the organization creates, receives, maintains, or transmits, regardless of where or how it is handled. HHS describes a documented process for identifying information, threats, vulnerabilities, safeguards, likelihood, and impact in its Guidance on Risk Analysis. A program-specific assessment can support the organization’s broader compliance work, but completing an assessment by itself does not establish that the organization complies with every HIPAA requirement.

How can teams map clinical workflows and identify security risks?

Start with the real sequence of care, including after-hours and high-volume scenarios. Walk through how a patient is identified, evaluated, imaged, discussed, transferred if needed, prepared for intervention, treated, and handed off for recovery or follow-up. Include the people and external partners who participate at each stage.

For every step, record what information is needed, who needs it, which system or device supplies it, and how it moves between teams. Note dependencies such as staff paging, secure messaging, image transfer, network connectivity, identity services, power, vendor support, and access to the procedure area.

Ask staff to describe how the workflow changes when a system is unavailable or a security concern arises. For example, determine how clinicians would access essential patient information during an EHR outage, how images would be reviewed if the usual imaging system were unavailable, and who can authorize a safe change in device or network status. Treat these as scenario questions for local planning—not assumptions that a single workaround will suit every hospital.

Then look for failure points: unclear ownership of an alert, shared accounts, outdated contact lists, manual handoffs that can misroute information, third-party connections that are not documented, or downtime procedures that have not been tested. Rank risks by both information impact and possible effect on care, and assign an owner and next step to each finding.

Which systems and medical devices require assessment?

Inventory systems and devices that create, use, store, transmit, or depend on stroke-related information—or whose failure could interrupt the care pathway. Include connections and supporting services, not just equipment physically located in the stroke unit.

• Clinical information systems: EHRs, electronic health record access controls, computerized order entry, medication systems, patient identity tools, and systems used for documentation and handoffs.
• Imaging and communications: CT and angiography imaging systems, picture archiving and communication systems (PACS), image-routing tools, radiology systems, secure messaging, phones, and paging.
• Procedure and monitoring equipment: Angiography equipment, anesthesia workstations, physiological monitors, infusion devices, and other connected equipment used along the care pathway.
• Infrastructure and access services: Networks, wireless access, identity and authentication services, remote access, servers, backups, power, and systems used for security monitoring.
• External services: Cloud platforms, telehealth or telestroke services, image-exchange partners, vendors, and other organizations that connect to program systems or handle relevant data.

For each item, document its location, owner, purpose, network connections, data handled, support contact, update process, known limitations, and role in patient care. Assess medical device cybersecurity in coordination with clinical engineering, IT, clinical leaders, and manufacturers or service providers where appropriate. The FDA’s medical device cybersecurity resources emphasize that healthcare delivery organizations should evaluate network security and work with other stakeholders to address risks that could affect device performance and patient safety.

Consider network segmentation as a possible way to limit unnecessary connections between systems and devices, but verify that any proposed separation preserves required clinical communication and vendor-supported operation. Segmentation is a safeguard to assess and validate in the local environment, not a substitute for understanding the device’s clinical dependencies.

How should teams evaluate physical security and emergency access?

Inspect the places where ePHI, workstations, network equipment, and medical devices are accessed or stored. Consider the ED, imaging areas, procedure rooms, recovery spaces, equipment rooms, supply and storage areas, and any locations where devices or media may be moved, serviced, or temporarily left unattended.

Review badge permissions, visitor identification and escort procedures, contractor access, after-hours entry, workstation positioning, unattended screens, equipment movement, and protection against tampering or theft. HIPAA’s physical safeguards address facility access, workstation security, and controls for devices and media; see 45 CFR § 164.310.

Separately assess how authorized clinicians can obtain necessary ePHI during an emergency and how the program continues care during system downtime. HIPAA requires an emergency access procedure for obtaining necessary ePHI, and the Security Rule also addresses audit controls. These requirements do not prescribe a particular “break-glass” design; teams should define, test, and review procedures that fit the organization’s systems and clinical workflows. See 45 CFR § 164.312.

Include practical tests: Can the right on-call clinician reach essential systems at night? Can authorized staff enter required areas during an emergency without compromising controlled access? Does the downtime process identify who makes decisions, how information is documented, and how records are reconciled when systems return?

What safeguards and response procedures should the assessment recommend?

Recommendations should address the specific risks identified and be workable during urgent care. Assign a responsible owner, implementation priority, target date, and method for checking whether each safeguard reduces the risk. When deciding among options, include both security effects and clinical workflow implications.

• Identity and access: Use individual accounts, role-based access control, appropriate electronic health record access controls, timely access changes when job responsibilities change, and monitoring of access activity. Define and review emergency access procedures.
• System and device protection: Maintain an accurate inventory, review device and system configurations, coordinate updates with clinical engineering and manufacturers, and assess segmentation or other connection controls against clinical requirements.
• Physical safeguards: Limit and validate access to sensitive areas, secure workstations and equipment, manage visitors and contractors, and document relevant equipment movement or maintenance.
• Continuity planning: Identify essential clinical information and workflows, maintain appropriate backups, and create and test downtime procedures for relevant systems and devices.
• Incident response: Maintain an incident response plan that identifies reporting channels, decision-makers, clinical escalation, technical response, documentation, communications, and recovery responsibilities.
• Practice and improvement: Train affected staff on local procedures and use exercises to reveal gaps in handoffs, contacts, emergency access, and downtime operations.

HIPAA requires policies and procedures to identify and respond to suspected or known security incidents, mitigate harmful effects where practicable, and document incidents and outcomes. The assessment should connect its findings to the organization’s incident response plan and other applicable procedures rather than treating a written plan as sufficient on its own. See 45 CFR § 164.308.

If a critical risk is identified, escalate it promptly to the program’s clinical and security leadership. First determine whether patient care is at immediate risk; use an agreed clinical safety process before isolating or changing a device or connection. Apply appropriate interim protections, involve relevant technical and clinical teams and vendors, preserve information needed for investigation, document decisions, and track corrective actions through completion.

What limitations should programs consider when applying a security assessment?

A risk assessment is a reasoned view of a changing environment, not a guarantee that every threat has been found or that every incident can be prevented. New technology, workflow changes, vendor connections, vulnerabilities, staff turnover, and incidents can alter the risk picture.

HIPAA does not set one universal schedule for repeating a risk analysis. HHS describes risk analysis as an ongoing process and explains that organizations should update their assessment as needed, including when they experience a security incident or introduce new technology. The review frequency should fit the organization’s environment and be supplemented by reassessment when meaningful changes occur. See the HHS risk analysis guidance.

Assessment results also depend on accurate inventories, honest workflow input, and participation from people who understand the systems and clinical work. A paper review may miss how staff actually respond under time pressure, so interviews, observation, technical review, and exercises can add useful evidence.

Finally, a safeguard can introduce operational trade-offs. For example, tighter access or network restrictions should be evaluated to ensure that authorized teams can still obtain needed information and that devices continue to function as intended. Apply protections proportionately, document decisions, and reassess them when the program changes.

In summary: A useful security risk assessment connects PHI safeguards, medical device cybersecurity, physical access, and emergency procedures to the realities of thrombectomy care. Map the workflow, prioritize risks by likelihood and impact, assign owners, test response and downtime plans, and revisit the assessment as systems and care processes evolve.

FAQs

Who should participate in a stroke program security risk assessment?

Include stroke and neurointerventional clinicians, the stroke program coordinator, nursing, emergency medicine, radiology, anesthesia, IT and cybersecurity, clinical engineering, privacy and compliance, facilities, and emergency management. Add relevant vendors, service providers, or partner organizations when they support systems or workflows in scope. The FDA’s medical device incident preparedness resources describe multidisciplinary participation that includes clinicians, healthcare technology management, IT, emergency response, risk management, and facilities staff; see the FDA cybersecurity resources.

How often should a thrombectomy-capable stroke program review security risks?

HIPAA does not specify one fixed interval for every organization. Treat risk analysis as ongoing, review it periodically under the organization’s governance process, and reassess when important changes occur—such as new technology, significant workflow changes, or a security incident. HHS discusses this approach in its Guidance on Risk Analysis.

How can security controls support time-critical stroke care?

Design controls around the actual care pathway. Clear role-based access, tested emergency access and downtime procedures, reliable communication routes, and carefully validated network controls can help authorized teams obtain the information and systems they need while protecting PHI. Exercise these procedures with the relevant clinical and technical teams so that staff know their roles when normal systems are unavailable.

What should a program do after identifying a critical security risk?

Escalate the finding to clinical and security leadership, evaluate immediate patient-safety implications, and agree on interim protections. Coordinate any device or network changes with the people responsible for clinical operation and technical support. Document the risk, decisions, and corrective actions; investigate and respond under the organization’s incident response plan if an incident may have occurred; and verify that the corrective action reduced the risk.
