Should organisations use the same identity controls for patients and clinicians?

Why This Matters for Security Teams

Healthcare identity cannot be treated as a single population because patients and clinicians sit on opposite sides of the assurance problem. Patients usually need low-friction, high-availability access from unmanaged devices, while clinicians need stronger proofing, rapid session recovery, and controlled access to PHI across shared workstations, mobile carts, and clinical apps. If the same policy is applied to both, teams often overcorrect with burdensome logins or undercorrect with weak assurance. NIST’s identity guidance and the NIST Cybersecurity Framework 2.0 both support aligning controls to risk, not forcing identical treatment across every user type. The same logic appears in NHI governance: role and context matter because access patterns, lifecycle, and revocation requirements differ materially. NHIMG research shows how quickly poor identity hygiene turns into exposure, with Ultimate Guide to NHIs noting that 97% of NHIs carry excessive privileges, a reminder that over-permissioning is a systemic failure, not a rare exception. In practice, many security teams discover this only after clinical workflow shortcuts or patient portal friction have already driven shadow access paths into production.

How It Works in Practice

A workable healthcare model starts by separating identity populations and then applying shared governance. Patients generally benefit from streamlined registration, step-up authentication only for sensitive actions, and device-agnostic recovery paths. Clinicians usually need stronger identity proofing, tighter role assignment, session controls, and integration with PAM and RBAC for high-risk functions. Current guidance suggests using one policy framework with different enforcement profiles, not one universal rule set.

• Use RBAC for clinician job functions, but avoid encoding patient and clinician rules into the same role tree.
• Apply JIT access for elevated clinical tasks, especially where break-glass access is required.
• Tie assurance to context, such as location, device posture, and sensitivity of the data being accessed.
• Use step-up authentication for transactions like prescription changes, record amendments, or proxy consent actions.
• Keep patient identity flows simple, but add stronger fraud and account recovery controls where abuse risk is higher.

For identity governance, the operational question is not whether the controls are identical, but whether the assurance level matches the action. That is consistent with the broader NHI lessons captured in Top 10 NHI Issues and the incident patterns in 52 NHI Breaches Analysis, where weak lifecycle control and excessive privilege repeatedly magnify impact. These controls tend to break down when hospitals rely on shared kiosks, emergency access, or fragmented EHR integrations because the identity decision is split across too many systems.

Common Variations and Edge Cases

Tighter identity controls often increase workflow friction, requiring organisations to balance fraud resistance against care delivery speed. That tradeoff is especially visible in emergency departments, telehealth, delegated access for parents or carers, and cross-organisation referrals. Best practice is evolving, and there is no universal standard for every edge case yet. For patients, the main exception is high-risk activity. Account takeover, benefits abuse, and proxy access may justify stronger proofing, shorter sessions, or repeated verification. For clinicians, the main exception is operational continuity. Break-glass workflows, on-call coverage, and temporary access during staff shortages often justify carefully governed exceptions, but those exceptions must be logged, reviewed, and time-bounded. The NHI lesson is still relevant here: even when access is legitimate, overbroad or long-lived privilege creates downstream risk. Healthcare teams should therefore prefer context-aware, reversible controls over blanket exemptions, and they should document the rationale for each identity population separately. That approach fits the governance direction in the Ultimate Guide to NHIs — Standards and aligns with the principle in NIST Cybersecurity Framework 2.0 that protection should be risk-based and outcome-driven. The practical rule is simple: separate the identity policies, keep the governance common, and make every exception explicit enough to survive audit.
