Concept Explanation

USP Chapter <800> provides the standards for the safe handling of hazardous drugs (HDs) to minimize the risk of exposure to healthcare personnel, patients, and the environment. This chapter applies to all healthcare personnel who handle HD preparations and all entities that store, prepare, transport, or administer HDs. According to the National Institute for Occupational Safety and Health (NIOSH), a drug is considered hazardous if it exhibits carcinogenicity, teratogenicity, reproductive toxicity, organ toxicity at low doses, or genotoxicity.

Key pillars of USP 800 include:

• Facility Design: HDs must be stored and prepared in negative-pressure rooms to prevent the spread of contaminated air.
• Engineering Controls: Use of Primary Engineering Controls (PECs) like Biological Safety Cabinets (BSCs) or Compounding Aseptic Containment Isolators (CACIs) is mandatory for sterile HD compounding.
• Personal Protective Equipment (PPE): Requirements include double chemotherapy-rated gloves, respiratory protection, and non-permeable gowns.
• Work Practices: Specific protocols for deactivation, decontamination, cleaning, and disinfection of work surfaces.

Understanding these standards is as vital as managing complex clinical conditions, such as those found in Easy NAPLEX Oncology Therapeutics Practice Questions, where many of the medications used are classified as hazardous drugs.

Solved Examples

Example 1: Proper Glove Selection
A pharmacist is preparing to compound a hazardous intravenous chemotherapy dose. According to USP 800, how many pairs of gloves should the pharmacist wear, and what type must they be?

1. Identify the requirement: USP 800 requires two pairs of gloves for handling HDs.
2. Identify the standard: The gloves must meet the ASTM D6978 standard for chemotherapy resistance.
3. Determine the placement: The outer glove must be worn over the cuff of the gown.
4. Final Answer: Two pairs of ASTM D6978 chemotherapy-rated gloves.

Example 2: Negative Pressure Requirements
An entity is designing a new cleanroom for hazardous compounding. What is the minimum required negative pressure (in inches of water column) for the Buffer Room relative to the adjacent positive-pressure ISO 7 anteroom?

1. Recall the pressure standard: USP 800 specifies a negative pressure between $0.01$ and $0.03$ inches of water column.
2. Assess the airflow: The air must flow from the cleaner area (anteroom) into the HD compounding area (buffer room) to contain hazardous vapors.
3. Final Answer: A minimum of $0.01$ inches of water column.

Example 3: Spill Kit Readiness
A pharmacy technician accidentally drops a vial of a hazardous drug in the receiving area. What is the immediate first step according to safety protocols?

1. Prioritize safety: The area must be restricted or cordoned off immediately to prevent exposure to others.
2. Access equipment: Obtain a hazardous drug spill kit.
3. Follow protocols: Personnel trained in spill management must clean the area using the contents of the kit (PPE, absorbent pads, neutralizing agents).
4. Final Answer: Cordon off the area and obtain a spill kit.

Practice Questions

1. Which organization maintains the list of hazardous drugs that fall under the scope of USP Chapter <800>?

2. What is the minimum number of Air Changes Per Hour (ACPH) required in a dedicated room used for the non-sterile compounding of hazardous drugs?

3. A pharmacist is unpacking a shipment containing hazardous drugs. If a package appears damaged, where should it be moved for further inspection?

4. True or False: Assessment of Risk (AoR) allows an entity to exempt certain HDs from some USP 800 requirements if the drugs are in final dosage forms (e.g., coated tablets).

5. Which specific type of primary engineering control (PEC) is acceptable for compounding sterile hazardous drugs?

6. When performing hazardous drug compounding, how often should the chemotherapy-rated gown be changed if not soiled?

7. A pharmacy is performing "deactivation" as part of their cleaning process. What is the primary goal of this step?

8. What type of respiratory protection is required when cleaning up a large hazardous drug spill that cannot be contained by a standard spill kit?

9. Where should the disposal container for chemotherapy-rated gowns and outer shoe covers be located?

10. According to USP 800, how often must personnel demonstrate competency in handling hazardous drugs?

Answers & Explanations

1. NIOSH (National Institute for Occupational Safety and Health): USP 800 refers to the NIOSH List of Antineoplastic and Other Hazardous Drugs in Healthcare Settings to define which medications require special handling.
2. 12 ACPH: For non-sterile HD compounding, the room must be externally vented and have at least 12 air changes per hour. For sterile HD compounding, this increases to 30 ACPH.
3. A Negative Pressure Area: Damaged HD packages should be moved to a Containment Primary Engineering Control (C-PEC) or a designated negative pressure area to prevent the spread of vapors or dust particles.
4. True: An entity may perform an Assessment of Risk for certain HDs (like finished dosage forms) to determine alternative handling strategies, provided they do not require manipulation (like crushing).
5. Biological Safety Cabinet (BSC) Class II or CACI: These units provide the necessary vertical laminar airflow and containment required for HDs. Horizontal hoods are strictly prohibited for HDs.
6. Every 2 to 3 hours: Gowns must be changed every 2-3 hours or immediately after a spill or splash to ensure the integrity of the protective barrier.
7. To render the compound inactive: Deactivation uses agents like sodium hypochlorite (bleach) to chemically transform the HD into a less toxic or non-toxic substance.
8. Full-face piece, chemical cartridge-type respirator or PAPR: While N95 masks protect against particles, they do not protect against vapors. A Powered Air-Purifying Respirator (PAPR) is often required for large spills.
9. Inside the C-SEC (Buffer Room): To prevent the spread of contaminants, PPE used in the compounding of HDs must be disposed of in the trace chemotherapy waste bin located within the hazardous compounding room.
10. At least every 12 months: USP 800 requires that competency be assessed and documented at least annually and whenever a new HD or new equipment is introduced.

Frequently Asked Questions

What is the difference between USP 797 and USP 800?

USP 797 focuses on the sterility and quality of the compounded preparation to protect the patient, while USP 800 focuses specifically on the safety of the healthcare worker and the environment when handling hazardous drugs.

Can I use an N95 mask for hazardous drug compounding?

An N95 mask provides protection against airborne particles but does not offer protection against the gases or vapors often emitted by hazardous drugs; therefore, it is not a substitute for proper engineering controls or specialized respirators.

What constitutes a "trace" chemotherapy waste container?

Trace waste containers, usually yellow, are used for items that have come into contact with HDs but are considered "empty" by RCRA standards, such as used PPE, empty vials, and IV bags.

Is a CSTD mandatory for drug administration?

USP 800 mandates the use of a Closed-System Drug-Transfer Device (CSTD) during the administration of hazardous drugs when the dosage form allows, as it provides an extra layer of protection for the nurse or practitioner.

Who must follow USP 800 standards?

Any healthcare setting that handles hazardous drugs, including retail pharmacies, hospital pharmacies, oncology clinics, and veterinary offices, must comply with USP 800 to ensure staff safety.

What is a C-SEC in USP 800?

A Containment Secondary Engineering Control (C-SEC) is the room in which the C-PEC (the hood) is placed, which must be externally vented, physically separated, and maintained under negative pressure.
