5 Key Factors to Consider When Selecting Isolation Gowns

In the world of healthcare and infection control, personal protective equipment (PPE) plays a crucial role in ensuring the safety of both patients and healthcare professionals. One essential component of PPE is the isolation gown, which is designed to protect against the transmission of infectious agents.

With numerous options on the market, it can be challenging to determine which gown is best suited for your needs. This article will discuss five key factors to consider when selecting isolation gowns to ensure you make the right choice.

1. Level of Protection

The primary purpose of an isolation gown is to provide a barrier between the wearer and potential contaminants. The level of protection required depends on the specific situation and the potential risks involved. The Association for the Advancement of Medical Instrumentation (AAMI) has developed a four-level classification system for isolation gowns:

  • Level 1: Designed for minimal-risk situations, such as basic care and standard isolation. These gowns offer minimal water resistance and are suitable for non-invasive procedures.
  • Level 2: Suitable for low-risk situations, such as blood draws and suturing. These gowns provide some water resistance and are ideal for situations with light fluid contact.
  • Level 3: Designed for moderate-risk situations, such as inserting an IV or working in the emergency room. These gowns offer moderate water resistance and are suitable for situations with moderate fluid contact.
  • Level 4: Suitable for high-risk situations, such as surgery or working with infectious diseases. These gowns provide the highest level of water resistance and are designed for situations with heavy fluid contact.

2. Material and Comfort

Isolation gowns are typically made from a variety of materials, each offering different levels of comfort, breathability, and protection. Common materials include:

  • Spunbond-Meltblown-Spunbond (SMS): A popular choice for its balance of comfort, breathability, and protection. SMS gowns are designed to be lightweight and comfortable while providing adequate fluid resistance.
  • Polyethylene-Coated Polypropylene: Offers a higher level of protection against fluids, but may be less breathable and comfortable than SMS gowns. These gowns are ideal for situations where fluid resistance is a top priority.
  • Polyester: A durable, reusable option that can be laundered and sterilized. Polyester gowns are comfortable and breathable but may provide less fluid resistance than other materials.

Consider the comfort and breathability of the gown, as well as the level of protection it offers, when making your decision.

3. Size and Fit

Isolation gowns come in various sizes and styles to accommodate different body types and preferences. When selecting a gown, consider the size and fit to ensure optimal protection and comfort. Gowns should fit securely, with ample room for movement and flexibility. Features such as adjustable neck and waist ties, elastic cuffs, and thumb loops can help improve the fit and function of the gown.

4. Reusability and Disposability

Isolation gowns are available in both reusable and disposable options. Reusable gowns are designed to be laundered and sterilized between uses, making them a more environmentally friendly and cost-effective option. Disposable gowns are designed for single use and are then discarded, reducing the risk of cross-contamination. Consider the frequency of use, available laundering facilities, and your organization's sustainability goals when selecting between reusable and disposable gowns.

5. Cost

The cost of isolation gowns can vary greatly depending on the material, level of protection, and whether they are reusable or disposable. While cost should not be the primary factor in your decision, it is essential to consider your budget and weigh the benefits of each gown option against its cost.


Selecting the right isolation gown is crucial in ensuring healthcare professionals' and patients' safety and protection. By carefully considering these factors, you can make an informed decision and choose an isolation gown that meets your specific needs.
