1.4 Designated Person, SOPs & the Hierarchy of Controls

Designated Person, SOPs & the Hierarchy of Controls

Quick Answer: USP <800> requires every facility handling hazardous drugs to appoint a qualified designated person responsible for developing, implementing, and maintaining HD-handling policies and procedures, ensuring staff competency, overseeing environmental quality and cleaning, and ensuring proper use of PPE and equipment. Facility policies should be built on the NIOSH hierarchy of controls — elimination/substitution, then engineering controls, then administrative controls (SOPs, training, signage, restricted access), with PPE as the last line of defense.

This section ties together the administrative-domain content: who is accountable for the HD program, what that person must produce (SOPs), and the risk-management framework (the hierarchy of controls) that should guide every decision the designated person makes.

The Designated Person: Role and Qualifications

USP <800> requires the facility to name a designated person — a single, accountable individual responsible for the facility's HD-handling program. This is not a title reserved for pharmacists only; the designated person must be qualified by education, training, and experience, and the role can be filled by a pharmacist, a nurse, or another qualified staff member depending on the setting, as long as they have the appropriate qualifications for the scope of the program they oversee.

Core designated-person responsibilities include:

Exam trap: candidates sometimes assume the designated person must be a pharmacist because HD handling is "a pharmacy issue." USP <800> does not restrict the role to pharmacists — the requirement is qualification by education, training, and experience, not a specific license type. In a hospital, the designated person overseeing nursing-unit HD administration practices may be a nurse with appropriate training, working alongside a pharmacy designated person for compounding-area oversight.

SOPs: The Designated Person's Core Deliverable

Standard operating procedures (SOPs) are the written expression of the facility's HD program, and USP <800> expects them to cover the full lifecycle of HD handling — not just compounding. A complete SOP set typically addresses: receiving and unpacking; storage; compounding (sterile and nonsterile); dispensing and final-dosage-form handling; administration; PPE selection and use; spill response; deactivation, decontamination, cleaning, and disinfection; waste disposal; and training/competency assessment. SOPs must be reviewed periodically and updated whenever the NIOSH list, procedures, or facility layout changes.

The Hierarchy of Controls

The hierarchy of controls is a NIOSH occupational-safety model ranking risk-reduction strategies from most to least effective. USP <800>'s administrative expectations are built around applying this hierarchy in order, rather than jumping straight to PPE:

1. Elimination/substitution — the most effective control: remove the hazard entirely, or substitute a non-hazardous or less-hazardous alternative when clinically appropriate.
2. Engineering controls — physical controls that isolate personnel from the hazard, such as certified primary engineering controls (BSCs, CACIs) and secondary engineering controls (negative-pressure rooms).
3. Administrative controls — SOPs, training, signage, restricted access, and workflow/scheduling choices that reduce exposure without removing the hazard or relying on physical isolation.
4. PPE — the least effective control on its own, and the last line of defense, used because it depends entirely on correct selection and consistent human use rather than removing or isolating the hazard.

Exam trap: a question may describe a facility that responds to an HD exposure incident by buying more chemo gloves (PPE) instead of examining whether an engineering control failed or an SOP was not followed. The hierarchy of controls says PPE should be the last layer added, not the first fix reached for — a facility investigating an exposure should look up the hierarchy (engineering and administrative controls) before assuming better PPE alone will solve the problem.

Exam Scenario

An infusion center director learns that a nurse was splashed with a hazardous drug during administration. Her first instinct is to order new, thicker chemo gloves for the unit. A better answer, applying the hierarchy of controls, is to first investigate whether an administrative control failed (was the SOP for that administration step followed? was the nurse trained and competent?) and whether an engineering control was appropriate and available (a closed system transfer device, for example) before concluding that PPE alone is the fix. The designated person is responsible for this kind of root-cause review and for updating SOPs and training based on the findings — PPE upgrades may still be part of the response, but only after the higher-priority controls have been evaluated.

Key Takeaways

• USP <800> requires a designated person, qualified by education/training/experience, who develops and maintains HD policies, ensures competencies, oversees environmental quality/cleaning, and ensures proper PPE/equipment use.
• The designated person role is not restricted to pharmacists — qualification, not license type, is the requirement.
• SOPs must cover the full HD lifecycle: receiving, storage, compounding, dispensing, administration, PPE, spill response, cleaning, and disposal.
• The hierarchy of controls ranks elimination/substitution first, then engineering controls, then administrative controls, with PPE as the last, least effective line of defense — apply it in that order when investigating or preventing exposure.
