Sepsis: A Health Concern for Older Adults

Posted by Helen Beamer on December 8, 2016 at 10:00 AM

People typically take precautions to avoid serious illnesses. We politely cover our mouths and noses during coughs and sneezes to prevent spreading germs.bacteria.png We wash our hands frequently. We keep a first aid kit for cuts and stings and have a thermometer handy to check for fevers. Then, as we age into our 60s, our doctors consistently remind us to stay up-to-date with immunizations for influenza, pneumonia, shingles, tetanus and pertussis.

Health organizations regularly inform us about the warning signs for heart attacks, strokes and various types of cancer. However, there’s another serious health condition that you may not know much about called sepsis, which is sometimes referred to as blood poisoning.

What is sepsis?

Sepsis is a potentially life-threatening condition caused by the body’s overwhelming response to an infection. It can lead to tissue damage, organ failure and death. Sepsis often occurs with infections of the lungs, urinary tract, skin or gut. Some common bacteria that may cause sepsis include staph, E. coli and strep.

Sepsis results in fever, rapid heart rate and breathing, and an increased white blood count. Severe sepsis means organs may be failing. This can progress to septic shock with dangerously low blood pressure, which can lead to lung, heart, kidney or brain failure. That’s why it is essential to get medical treatment immediately at the first signs of sepsis.

Older adults and sepsis

More than one million Americans develop severe sepsis each year. While sepsis can occur in anyone or at any age, it happens most often in older adults. Approximately 65 percent of sepsis cases occur in people over the age of 65.

Here are four reasons why older adults are especially vulnerable to sepsis:

  1. Chronic medical conditions: Having chronic health condition such as diabetes, cancer, immunodeficiency virus (HIV) or kidney disease can increase an individual’s susceptibility to sepsis. According to the Centers for Disease Control (CDC), over 90 percent of adults with sepsis had an underlying health condition.
  2. Functional limitations: Functional status, that is the ability to get around and independently care for oneself, can influence health. An inactive lifestyle, muscle loss, inadequate food intake or cognitive impairment can impair bodily functions and strength; thus, increase the risk of sepsis.
  3. Immune system: Aging compromises the immune system. In addition, the expected warning signs of an infection may be not apparent in the elderly. For example, in many older adults the first sign of a urinary tract infection is a change in mental status – becoming confused or disoriented – rather than typical symptoms such as the need to urinate or painful urination. Due to changes in the immune system, sepsis in the elderly may also take a more rapid course, leading quickly to septic shock or death.
  4. Advanced age: Various studies find old age itself is a risk factor for severe sepsis, and the consequences of sepsis can be significant. According to a 2010 study, nearly 60 percent of older adults who recovered from severe sepsis experienced a decline in cognitive and/or physical function. The researchers note these changes create “lasting implications for patients' independence, for their loved ones, and for the societal institutions charged with supporting them.” Death rates associated with severe sepsis also increase with advancing age – with the highest mortality in those 85+.

Signs of sepsis

Given the potential risks and long-lasting consequences, it’s important to know the signs of sepsis. According to the CDC, sepsis may include signs of infection, such as vomiting or diarrhea as well as any of the following symptoms:sepsis-signs-cdc.gif

  • Shivering, fever or very cold
  • Extreme pain or discomfort
  • Clammy or sweaty skin
  • Confusion or disorientation
  • Shortness of breath
  • High heart rate

“Another change you may see,” said Sharon Holmes, ComForCare and At Your Side Home Care director of nursing and accreditation, “is that the skin may become blotchy or bluish in color.”

The CDC advises that if you suspect sepsis in yourself or a loved one, call your doctor or go to an emergency department immediately. Be sure to say, “I am concerned about sepsis.”

Be aware that in addition to the symptoms listed above, elderly people may exhibit nonspecific signs of sepsis, including altered mental status, delirium, weakness, falls and urinary incontinence.
