Kennedy Ulcer: Questions & Answers

Kathleen Martin, RN, MSN, MPA, LNHA, CPHQ

 

 1. What is a Kennedy Terminal Ulcer?

A Kennedy Terminal Ulcer is a pressure ulcer some people develop as they are dying.

 

2. What does a Kennedy Terminal Ulcer look like?

It usually presents on the sacrum. It can be shaped like a pear, butterfly or horseshoe. It can have the colors of red, yellow, black or purple. The borders of the ulcer are usually irregular. It has a sudden onset. The two statements you hear most are: 1: “Oh, my gosh, that was not there the other day.” 2: “I worked Friday, it was not there then, I was off the weekend and when I came back on Monday there it was.”

 

3. How does a Kennedy Terminal Ulcer progress?

It usually starts out as a blister or a Stage II and can rapidly progresses to a Stage III or a Stage IV. In the beginning it can look much like an abrasion as if someone took the patient and drug his or her bottom along a black top driveway. It can become deeper and starts to turn colors. The colors can start out as a red/purple area then turn to yellow and then black.

 

4. How are these different than other pressure

ulcers?

They can start out larger than other pressure ulcers, are usually more superficial initially and develop rapidly in size, and depth and color.

 

5. What kind of treatment is best for a Kennedy

Terminal Ulcer?

Treatment for a Kennedy Terminal Ulcer is the same as for any other pressure ulcer with the same characteristics. What you see is what you treat. When it is in the blanchable/or non-blanchable intact skin stage the goal would be to relieve the pressure and protect the area. When it becomes a Stage II or a partial thickness ulcer usually there is not a lot of drainage and a thin film, hydrocolloid, foam or gel may be indicated. When it is a full thickness wound, Stage III or IV depending on the amount of drainage you could use a hydrocolloid, foam, gel, or calcium alginate. If there is necrotic tissue slough (yellow tissue) or eschar (black, brown, beige or tan tissue) you may want to use an enzymatic debriding agent. If it becomes clinically infected you may want to consider a dressing with silver. Due to the fact that such ulcers occur in the terminally ill, the comfort of the person is of the utmost importance in deciding on the course of treatment.

 

6. What causes a Kennedy Terminal Ulcer?

Further research needs to be done on this subject. However, one idea is it may be a blood perfusion problem exacerbated by the dying process. The skin is an organ, just like the heart, lungs, kidneys, lungs and liver. It is the largest of the body organs and is the only one that is on the outside of the body. It can reflect what is going on inside the human body. One theory is as people are approaching the dying process the internal organs begin to slow down and go into what is thought of as multi-organ failure. This is where all the organs start to slow down and not function as efficiently as previously. Skin failure can occur just as any other organ can fail in this process. No particular symptomatology may be detected except the skin over bony prominences starts to show effect of pressure in a shorter time frame. Where as turning a patient every two hours may be enough in somewhat of a normal situation it now may cause superficial tissue damage.

 

7. Can a Kennedy Terminal Ulcer get better?

Yes, and no.

The majority of them do not. It is something that is generally thought to be terminal. However, it has been known for a patient that was terminal or at the end of life and the patient or family decided they did want intravenous or tube feeding intervention along with other appropriate modalities to change their mind and decide they did want all available interventions. At that point I have known of patients to have this phenomena reversed, but it is rare.

 

8. When was a Kennedy Terminal Ulcer first

described?

In March of 1989 the National Pressure Ulcer Advisory Panel put together their first conference in Washington D.C. The conference was to help determine how many pressure ulcers there were (prevalence) and could you predict who was going to get them.

 

9. What age group is this prominent in?

Further research needs done but it tends to be a geriatric phenomenon. It does not seem to be prominent in pediatrics. It is reported frequently in hospice patients, but is not exclusive to this population.

 

10. How did it get its name?

It was named by the Medical Director of the Byron Health Center is Fort Wayne, Indiana, Dr. Stephen Glassley. He termed it “The Kennedy Terminal Ulcer”. Naming it after the first Family Nurse Practitioner, in Fort Wayne, Indiana, Karen Lou Kennedy. Record keeping was initiated indicating some patients developed pressure ulcers with similar characteristics that went on to die in a short time frame. As the data was reviewed a pattern developed as to the characteristic and time frame from onset to death. This data was reviewed by the medical director, thus naming it the “Kennedy Terminal Ulcer”.

 

11. Why have I not heard of this before?

This was first described in modern literature by Karen Lou Kennedy in 1989 in Decubitus (now known as Advances in Skin & Wound Care) Vol.2, No,2, May 1989. p.44-45

However, in about 2002 Dr. Jeffrey M. Levine, MD, AGSF, found a long lost textbook published in 1877 by professor Dr. Jean-Martin Charcot called Lectures the Diseases of The Nervous System. Dr. Charcot was a French neurologist considered the father of modern neurology and the first professor of diseases of the nervous system regarded as one of the most important researchers in the field of clinical neurology of the 19th century. This ulcer, not named as such yet, was described here.
