Protective Isolation: What Is It and Why Do I Need It?
by Marjorie Montemayor-Quellenberg, MA
Our immune system keeps us healthy by fighting organisms from our everyday environment, like bacteria and viruses, which could possibly harm us. However, when we are immunocompromised (have a weakened immune system), common organisms become a threat since our bodies are unable to fight them off.
This is when protective isolation is helpful. Doctors, nurses, and other hospital staff practice protective isolation to make sure that patients with weakened immune systems are not exposed to organisms that could potentially lead to infection and serious complications. If you are admitted to the hospital and are under protective isolation, here are actions that the staff will take to protect you.
You may be given your own hospital room. The staff will take steps to keep your room clean during your stay. This may include:
Hospital Staff and Visitors
Hospital staff and visitors, like your family and friends, may be dressed in protective clothing when they enter your room in some cases. They may be wearing disposable:
In addition to protective clothing, staff and visitors will clean their hands, by either washing with soap and water or using an alcohol-based hand sanitizer, before entering. Studies have shown that hand washing is one of the most effective ways to prevent the spread of diseases.
Your doctor or nurse may want to limit the number of visitors you receive. They may also discourage small children from visiting. These precautions are in place to lessen the chance of exposure to different viruses and bacteria. Those family and friends who do visit should be certain that they are not sick. Even the mildest symptoms can put you at risk, so it is important that visitors are healthy.
Steps You Can Take
Aside from precautions that staff and visitors will take, there are things you can do to prevent infections from transmitting to you, and vice versa:
You may need to follow a special diet while you are in the hospital. Your nurse or dietitian will work with you to provide meals specific for weakened immune systems. For instance, you may only be able to drink bottled water or specially filtered water and pasteurized juices, since these are less likely to have bacteria. Also, you will use eating utensils and dishes that have been properly sanitized, or you may be given disposable utensils and dishes to use.
Your doctors, nurses, and other staff want to ensure that your hospital stay is both comfortable and safe. Strict protective isolation procedures are in place for your protection. If you, your family, or friends have any concerns or questions about the procedures, be sure to talk to the staff.
