Skin conditions are a common concern in nursing sick call evaluations. Most are easy enough to assess and treat; whether athlete’s foot or contact dermatitis. However, one skin condition that can be dangerous if not spotted and treated appropriately is cellulitis. Unfortunately, cellulitis can mimic other conditions and is easily misdiagnosed. Here is a quick clinical overview of cellulitis to help you determine if the next skin condition you evaluate in sick call needs a provider appointment.
What is Cellulitis?
Cellulitis is a bacterial infection of the skin and tissues underneath. It is most common in the lower extremities but can also affect other areas such as these.
- Eyes – from sinus infection
- Ear, nose, or abdomen – from piercings
- Arms, neck, feet – from skin popping (drug use)
While cellulitis develops through a break in the skin, that opening may be microscopic and hard to detect. Staphylococcus aureus is the most common cause of cellulitis, and, increasingly, that staph is in the form of MRSA. A less common infecting agent is streptococcus. Group A streptococcus (GAS) is a bacteria that leads to necrotizing fasciitis (commonly called ‘flesh-eating bacteria’).
What Does It Look Like?
Cellulitis presents as diffuse inflammation. It is rarely bilateral so if the skin condition is on both lower legs it is likely something else, such as venous insufficiency. Because cellulitis includes inflammation of both skin and underlying tissue, it is less likely to have clearly defined borders. Drainage can sometimes be present and that could mean the causative agent is MRSA.
This condition will present with the usual signs of infection: redness, swelling, warmth, and tenderness over the affected area. If the cellulitis has progressed, your patient may feel generally unwell with a fever, chills, sweating, and overall body ache. If left untreated, the infection will spread systemically and can lead to confusion, rapid heart rate, increased respiratory rate and low blood pressure. If not halted the systemic invasion becomes sepsis and life-threatening.
Who is Likely to Develop Cellulitis?
Knowing the risk factors for this condition will help you be particularly aware of its potential with certain groups of patients. Here are the most common risk factors for developing cellulitis.
- Weak or suppressed immune system
As you can see, many in our patient population have multiple risk factors for cellulitis especially when we consider that alcoholism and drug misuse lead to poor nutrition.
What is the Current Treatment?
As cellulitis is a bacterial infection, treatment is dependent on antibiotic administration specific to the causative agent. There is no consensus in the literature as to when oral or IV antibiotics are most beneficial. Advanced cases of cellulitis will require hospitalization. The evidence-based CREST guidelines for cellulitis suggest antibiotics that cover both strep and staph infection such as flucloxacillin (floxacillin) or clindamycin.
What are the Nursing Goals?
The first nursing priority is to quickly determine that this patient needs to see a medical provider. Once diagnosed, nursing interventions focus on administering prescribed antibiotics, monitoring side effects and providing supportive therapies. Below are key nursing actions.
- Confirm allergy profile – especially penicillin allergy
- Document a thorough initial assessment and ongoing assessment at regular intervals
- Monitor for antibiotic side effects such as gastric upset, diarrhea, rash, or yeast infection
- Document pain level and provide analgesics, if ordered
- Provide patient education regarding extremity elevation, side effect monitoring, and proper skin care
