Hip Fracture with MRSA Cellulitis: A Comprehensive HESI Case Study Analysis

This case study delves into a complex scenario involving a patient with a hip fracture complicated by MRSA cellulitis. We will explore the pathophysiology, clinical presentation, diagnostic process, treatment strategies, and nursing considerations associated with this challenging condition. Understanding this case will enhance your ability to manage similar situations, particularly within the context of the HESI exam.

Patient Presentation: A 78-Year-Old Female with a History of Falls

Our patient, a 78-year-old female, presents to the emergency department after a fall at home. She reports experiencing immediate, severe pain in her right hip. Her medical history is significant for osteoarthritis, hypertension, and a history of recurrent urinary tract infections. On physical examination, she exhibits significant distress, guarding her right hip, and is unable to bear weight. Her right leg is externally rotated and shortened. Furthermore, a large, erythematous, warm, and tender area is noted on her right thigh, exhibiting signs of significant inflammation. This area is accompanied by purulent drainage. The patient reports increasing pain and swelling in this area over the past three days.

Initial Assessment and Diagnostic Workup: Identifying the Dual Challenge

Initial Vital Signs: Blood pressure 160/90 mmHg, heart rate 100 bpm, respiratory rate 22 breaths/minute, temperature 101.2°F (38.4°C). The elevated temperature and tachycardia are indicative of an infectious process.

Assessment of Hip Fracture: The initial clinical presentation strongly suggests a hip fracture. This is confirmed by radiographic imaging (X-ray), revealing a displaced intertrochanteric fracture of the right femur. The external rotation and shortening of the leg are classic signs.

Assessment of Cellulitis: The extensive erythema, warmth, tenderness, and purulent drainage on her right thigh strongly indicate cellulitis. The severity suggests a potentially serious infection. Gram staining and culture of the drainage are immediately ordered to identify the causative organism. The results indicate Methicillin-resistant Staphylococcus aureus (MRSA).

Additional Investigations: A complete blood count (CBC) reveals leukocytosis (elevated white blood cell count), indicating the body's response to infection. Blood cultures are drawn to rule out systemic infection (bacteremia). Basic metabolic panel (BMP) is also obtained to assess renal and electrolyte balance, given the patient's age and co-morbidities. A chest X-ray is performed to rule out pneumonia, a common complication in elderly patients.

Understanding the Pathophysiology: A Two-Front Battle

Hip Fracture Pathophysiology: Hip fractures are common in elderly individuals, often resulting from falls. The underlying cause is frequently osteoporosis, leading to weakened bones susceptible to fracture. The intertrochanteric region is a common fracture site. The fracture itself causes significant pain, immobility, and risk of complications such as deep vein thrombosis (DVT), pulmonary embolism (PE), and pressure ulcers.

MRSA Cellulitis Pathophysiology: MRSA cellulitis is a serious skin infection caused by methicillin-resistant Staphylococcus aureus, a bacterium resistant to many commonly used antibiotics. The bacteria invade the deeper layers of the skin, causing inflammation, pain, swelling, and purulent drainage. The infection can spread rapidly, leading to significant morbidity and mortality, especially in immunocompromised individuals. In this case, the likely entry point for the MRSA infection is related to a minor skin break or wound that went unnoticed or untreated. The trauma associated with the fall may have exacerbated this.

Treatment Plan: A Multifaceted Approach

The patient's condition requires a multidisciplinary approach encompassing surgical intervention for the hip fracture and aggressive antibiotic therapy for the MRSA cellulitis.

Surgical Management of Hip Fracture: Given the displaced nature of the fracture, surgical intervention is necessary for reduction and stabilization. Options include open reduction and internal fixation (ORIF) or hemiarthroplasty (partial hip replacement), depending on the patient's overall health and the fracture pattern. ORIF involves surgically realigning the bone fragments and securing them with implants (plates and screws). Hemiarthroplasty replaces only the femoral head with a prosthetic component. The choice depends on factors such as bone quality, patient age, and overall health.

Antibiotic Therapy for MRSA Cellulitis: Due to the MRSA infection, the patient requires intravenous (IV) antibiotics. Vancomycin is a common first-line treatment for MRSA cellulitis. The choice and duration of antibiotic therapy will depend on the culture results and the patient’s response to treatment. Monitoring for signs of improvement or adverse effects from the antibiotics is crucial.

Pain Management: Effective pain management is crucial for both the fracture and the cellulitis. Analgesics, including opioids and non-opioid options, are administered to control the patient's pain levels. Regular pain assessments are essential to optimize pain management strategies.

Supportive Care: The patient requires supportive care measures such as fluid resuscitation to maintain adequate hydration, nutritional support to promote healing, and measures to prevent complications like DVT (e.g., compression stockings, anticoagulants) and pressure ulcers (e.g., regular repositioning, pressure-relieving mattresses).

Nursing Considerations: Prioritizing Safety and Healing

Nursing care for this patient is multifaceted and requires attention to detail.

Infection Control: Strict adherence to infection control protocols is paramount to prevent the spread of MRSA. This involves proper hand hygiene, use of personal protective equipment (PPE), and appropriate isolation precautions. Proper wound care and disposal of contaminated materials are critical.

Pain Management: Regular pain assessments are crucial. The nurse must be diligent in administering analgesics as prescribed, monitoring for side effects, and using non-pharmacological pain management techniques like repositioning and relaxation exercises.

Mobility and Rehabilitation: Post-surgical rehabilitation is vital. The patient will require assistance with mobility and activities of daily living. Physical and occupational therapy will play a crucial role in restoring functional independence.

Monitoring for Complications: Close monitoring is essential for early detection and management of potential complications, including DVT, PE, pneumonia, and sepsis. Regular vital sign monitoring, assessing for signs of infection, and promptly reporting any changes to the medical team are crucial.

Wound Care: Careful wound care is crucial for the cellulitis. This includes monitoring the wound for signs of healing or worsening infection, providing appropriate dressings, and administering antibiotics as ordered.

Patient Education: Patient and family education about the condition, treatment plan, and potential complications is essential. Instructions on medication administration, wound care, mobility exercises, and follow-up appointments are vital.

Potential Complications and Management: Anticipating Challenges

Several potential complications need to be proactively addressed.

Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE): Immobility increases the risk of DVT and subsequent PE. Prophylactic measures, such as compression stockings and anticoagulation therapy, are essential. Regular assessments for signs of DVT (leg pain, swelling, warmth) and PE (shortness of breath, chest pain) are crucial.

Sepsis: The spread of MRSA infection to the bloodstream can lead to sepsis, a life-threatening condition. Close monitoring of vital signs, signs of infection, and prompt administration of antibiotics are critical.

Pressure Ulcers: Immobility increases the risk of pressure ulcers. Regular repositioning, pressure-relieving mattresses, and meticulous skin care are necessary.

Pneumonia: Elderly patients are at increased risk of pneumonia. Regular respiratory assessments, including auscultation of lung sounds, are crucial.

Delayed Union or Nonunion of Fracture: Failure of the fracture to heal properly is a possibility. Regular radiographic monitoring and appropriate intervention are necessary if this occurs.

Post-Operative Infection: Infection at the surgical site is a potential complication. Close monitoring for signs of infection, such as redness, swelling, drainage, and fever, is critical.

Ethical Considerations: Patient Autonomy and Informed Consent

Ethical considerations are paramount in managing this patient. Informed consent is critical for all medical interventions, including surgery and antibiotic therapy. The patient's wishes and preferences regarding treatment options must be respected. Discussions with the patient and family regarding the risks and benefits of different treatment options should occur, especially considering the patient's age and comorbidities. The decision-making process must be sensitive to the patient's autonomy and dignity.

Discharge Planning: Ensuring a Smooth Transition

Thorough discharge planning is essential for a successful transition to the home environment. This includes arranging for home healthcare services, such as wound care and physical therapy. The patient and family should receive detailed instructions on medication administration, follow-up appointments, and potential complications to watch for. Provisions should be made for assistance with activities of daily living.
