What breaks when healthcare organisations rely on manual approval workflows for access to electronic health record systems?

Approval bottlenecks and access drift in clinical environments

Manual approval workflows seem attractive because they add a human checkpoint, but in healthcare they often move the real problem from access control to queue management. When every request waits on a person, the organisation creates delay, inconsistency, and pressure to grant broader access than intended. That undermines the purpose of access governance and makes it harder to support time-sensitive clinical work safely. For context on how access decisions and control discipline are expected to support secure operations, see OWASP Non-Human Identity Top 10.

In practice, many healthcare teams discover the weakness only after urgent clinical access has already been delayed or exceptions have already become the normal path.

What manual approval actually changes in EHR access flows

Manual review does not just slow the first request. It changes the entire lifecycle of access by making provisioning, renewal, and removal depend on individual attention rather than a consistent rule set. That creates uneven outcomes across roles, shifts, departments, and temporary staff. A clinician may receive access late, another may receive too much access because reviewers want to avoid rework, and a third may keep access longer than needed because nobody wants to interrupt patient care. The control failure is not simply “humans are slower”; it is that human-dependent approvals do not scale cleanly to the pace and volatility of healthcare operations.

Where approvals are hand-run, the organisation also tends to lose reliable evidence about why access was granted, whether the approver had the right authority, and whether the access matched the role or clinical need. That makes audits harder and weakens accountability. It also creates a gap between policy and practice, because the policy says access is controlled while the workflow encourages exceptions to keep services moving. In a busy care setting, those exceptions can quietly become the default operating model.

• Onboarding is delayed when access depends on a queue rather than a pre-defined role or event trigger.
• Temporary access is harder to time-box, so it is often granted broadly and revoked late.
• Approver fatigue increases the chance of inconsistent decisions across similar users.
• Support teams absorb the friction by requesting shared accounts, standing privilege, or wider access than necessary.

NIST’s control catalogue is useful here because it distinguishes between authorisation, account management, and auditability rather than treating approval as a standalone safeguard. See NIST SP 800-53 Rev 5 Security and Privacy Controls. Where the workflow cannot reliably express role, duration, and revocation, the model breaks down into manual exception handling instead of governance.

The guidance stops being dependable when the organisation cannot track who approved what, cannot revoke access promptly, or must repeatedly override the process to keep clinical operations running.

When manual approval is a stopgap, and when it is a liability

Tighter approval often increases operational friction, so healthcare organisations must balance control strength against clinical timeliness. That tradeoff is acceptable for unusual, high-risk access requests, but it becomes a liability when it is used for routine onboarding, routine temporary access, or repeated access renewals. At that point the workflow is no longer acting as a control layer; it is becoming a throughput constraint that encourages workarounds.

There is also a practical distinction between approval for exceptional access and approval for standard access. Standard access should usually be policy-driven and repeatable, while exceptional access should remain review-heavy and time-limited. Guidance versus consensus is not fully settled on exactly how much human approval should remain in EHR administration, but there is broad agreement that repeatable access patterns should not depend on ad hoc manual processing. The more predictable the role, the less value manual approval adds.

Healthcare organisations also need to watch for edge cases such as locum clinicians, cross-site staff, and emergency break-glass scenarios. These cases justify faster or broader access in limited circumstances, but they require strong expiry rules and post-event review. Without that discipline, the exception path becomes indistinguishable from ordinary access. The common failure is not the existence of exceptions; it is the lack of a reliable exit from them.

Practitioner Guidance

What to prioritise: Treat routine EHR access as a lifecycle problem, not an approval problem. The highest-value fix is to make standard access predictable, time-bound, and revocable, while reserving manual review for true exceptions.

What to verify: Confirm that approvers are validating role, duration, and clinical need rather than simply clicking through requests. If those three elements are not explicit, the workflow is likely producing approvals without meaningful control.

Decision rule: If access is needed for a recurring job function, move it out of ad hoc manual review. If access is genuinely unusual, keep the manual step but make expiry and review mandatory so the exception does not become permanent.

Practitioner takeaway: The main danger is not slow approval alone; it is that delay pushes teams toward broader, less accountable access patterns that are harder to unwind than the original workflow was to operate.
