PPE

An isolation gown is personal protective equipment (PPE) worn to create a barrier against blood, body fluids, secretions, excretions, and contaminated surfaces. This barrier is especially important during activities where clothing or forearms may come into contact with the patient or the patient environment. Isolation gowns are commonly used under: • Routine practices (standard precautions) when contamination risk is anticipated • Transmission-based precautions (e.g., contact and droplet/contact precautions), where gowns may be recommended on room entry depending on organism and facility policy Key clinical reality: gowns work best as part of a system—hand hygiene, correct glove use, environmental cleaning, and safe donning/doffing practices remain essential.

In Canadian practice, gown decisions are often guided by a Point-of-Care Risk Assessment (PCRA)—a quick evaluation of the patient, the environment, and the task before every interaction. If your clothing or skin may be exposed to splashes/sprays or contaminated surfaces, a gown is typically indicated. Common scenarios where isolation gowns add meaningful protection • Direct patient care with extensive contact (turning, bathing, repositioning, linen changes) • Wound care or procedures with drainage/exudate • Tasks with splash/spray risk (irrigation, suctioning, GI care, cleaning bodily fluid spills) • Care in contact/droplet-contact rooms when staff clothing may contact the patient or environment .

Not all gowns provide the same level of fluid resistance. Many facilities align gown selection with ANSI/AAMI PB70 barrier classifications (Levels 1–4). In plain terms: higher levels generally provide greater resistance to liquid penetration for higher-risk tasks. A helpful way to think about AAMI levels: • Level 1 (minimal risk): basic care and standard isolation/visitor cover gowns in low-fluid situations • Level 2 (low risk): blood draws, suturing, lab tasks where light fluid exposure may occur • Level 3 (moderate risk): higher-contact clinical tasks, IV insertion, emergency/trauma settings with increased fluid exposure potential • Level 4 (highest barrier): tested for viral penetration resistance; typically reserved for higher-risk, higher-fluid procedures Practical takeaway: gown selection should match the anticipated exposure—not just the unit type. A short interaction may still require a higher barrier if splash risk is present.

From an IPAC and operational perspective, the “right” gown balances protection, usability, and workflow fit. Clinical selection checklist • Barrier level appropriate to task (risk of splashes, sprays, soiling, heavy contact) • Coverage where it counts: full front coverage and sleeve coverage that supports glove overlap • Secure closures and comfortable fit: helps reduce adjustments that can contaminate hands • Durable materials and seams suitable for movement (repositioning, transfers) • Sizing availability: correct size improves coverage and reduces tearing Single-use vs reusable Both approaches can be appropriate. Disposable gowns support convenience and surge readiness; reusable gowns can be effective when laundering processes and gown integrity checks are consistently managed. Many organizations choose based on workflow, supply resilience, and environmental goals (often using a hybrid approach).

Even high-performing gowns can fail to protect if donned/doffed poorly—especially during removal, when the outer surface should be treated as contaminated. Good practice typically includes: • Don gown before gloves • Ensure gloves cover gown cuffs • Remove and discard (or contain for laundering) before leaving the patient care space • Perform hand hygiene immediately after PPE removal During contact precautions, the CDC emphasizes gown and glove use for interactions that may involve contact with the patient or their environment, and discarding PPE before exiting the room to help contain pathogens.

Isolation gowns are often discussed as a “requirement,” but their real utility is operational: • Reduced occupational contamination: fewer uniform/clothing contamination events, fewer workflow interruptions • More consistent patient-zone boundaries: helps teams maintain cleaner movement between spaces • Improved staff confidence during high-demand periods: when PPE is available and easy to use correctly • Better standardization: when gown selection is risk-based and simplified, compliance becomes easier to sustain In short: gowns help maintain a predictable, safer care environment when contact and fluid exposure risks are part of everyday clinical reality.

They may look similar, but intended use and performance expectations can differ. Facilities often use AAMI classifications and procurement specifications to ensure the correct gown type for the clinical context.

Canadian guidance frames gown use around contamination risk—when clothing or skin may be exposed to body fluids or contaminated surfaces, based on PCRA.

Canadian guidance frames gown use around contamination Higher barrier protection is valuable when fluid exposure risk is higher, but comfort, heat burden, task duration, and mobility also matter. The best choice is the gown that meets the risk profile and supports correct use for the full task.

At BND Inc.—BioNuclear Diagnostics Inc., we focus on practical PPE solutions that align with healthcare workflows. When selecting isolation gowns, we recommend a risk-based approach—matching barrier performance to the task, ensuring appropriate sizing, and supporting consistent use across care settings. If your team is reviewing PPE standards, unit stocking, or barrier level alignment, BND can help you evaluate gown options based on: • anticipated exposure risk (PCRA-driven), • unit workflows, • and AAMI-rated barrier needs.
