Hospital Acquired Pressure Injury - Nursing Case Study

Pathophysiology

• Primary mechanism: Prolonged pressure on the skin compresses blood vessels, leading to ischemia and tissue necrosis. This impairs cellular metabolism and causes skin breakdown, particularly over bony prominences.

• Secondary mechanism: Shear forces exacerbate tissue damage by distorting and stretching blood vessels, further compromising blood flow and contributing to deeper tissue injury beyond the visible ulcer.

• Key complication: These injuries can lead to infection, as the compromised skin barrier allows pathogens to invade, potentially resulting in cellulitis or even systemic infection if not managed promptly.

Section 1

New Diagnostic Results:

Following the initial presentation, the healthcare team conducted a comprehensive assessment and ordered several diagnostic tests to evaluate the extent of the pressure injury and potential complications. Laboratory results revealed an elevated white blood cell count of 14,000/mm³, indicating a possible infection. C-reactive protein levels were also elevated at 6.5 mg/L, further supporting systemic inflammation. Blood cultures were taken to identify any bacteremia, with preliminary results suggesting gram-positive cocci, consistent with a possible Staphylococcus aureus infection.

The wound culture of the sacral ulcer identified moderate growth of methicillin-sensitive Staphylococcus aureus (MSSA), confirming a localized infection. Imaging studies, including an X-ray of the sacral area, did not show any signs of osteomyelitis, but the depth of the ulcer was significant, reaching the subcutaneous tissue and posing a risk for further complications. The interdisciplinary team concluded that the infection was localized but required aggressive management to prevent progression to systemic involvement.

These findings necessitate immediate intervention to address the infection and prevent further deterioration. The patient was started on intravenous antibiotics tailored to the culture results, alongside wound care management involving regular debridement and specialized dressings to promote healing. The healthcare team emphasized the importance of controlling blood glucose levels and managing hypertension to optimize wound healing. With these interventions underway, the focus shifts to closely monitoring the patient's response to treatment and preventing potential systemic complications.

Section 2

As the healthcare team continued to monitor the patient's response to the interventions, significant changes in the patient's status emerged. Over the next 48 hours, the patient began exhibiting signs of increased discomfort and malaise. Vital signs revealed a persistent low-grade fever of 38.2°C (100.8°F), despite the initiation of intravenous antibiotics. Additionally, the patient reported increased pain at the ulcer site, which was now more erythematous and swollen. The wound exudate had become more purulent, raising concerns about the effectiveness of the current antibiotic regimen.

Laboratory tests showed a further rise in the white blood cell count to 16,500/mm³, indicating a potential escalation of the infection. Repeat blood cultures were drawn, and preliminary results again suggested the presence of gram-positive cocci, raising the suspicion of a possible developing bacteremia. The C-reactive protein level had also increased to 9.2 mg/L, suggesting an ongoing inflammatory response. The interdisciplinary team recognized the need to re-evaluate the current management plan, considering the patient's worsening clinical picture and potential progression to a more systemic infection.

In response to these developments, the healthcare team initiated a broad-spectrum antibiotic regimen to cover potential resistant organisms while awaiting the final blood culture results. The wound care protocol was intensified, incorporating advanced debridement techniques and negative pressure wound therapy to facilitate drainage and promote healing. The team also consulted an infectious disease specialist to provide input on optimizing the antibiotic strategy. The focus remained on closely observing the patient's clinical status, with particular attention to any signs of sepsis or systemic involvement, to ensure timely intervention and prevent further complications.

Section 3

As the healthcare team continued to monitor the patient's progression, they noted a change in the patient's status that warranted immediate attention. Over the following 24 hours, the patient's vital signs shifted, with the heart rate increasing to 112 beats per minute and blood pressure dropping to 88/56 mmHg, raising alarms for potential hemodynamic instability. The patient also experienced increased confusion and lethargy, deviating from their baseline mental status, which suggested the onset of systemic involvement. These signs, coupled with the persistent fever, indicated the possibility of sepsis, prompting the need for rapid and decisive intervention.

New diagnostic results further informed the team's clinical reasoning. The repeat blood cultures confirmed the presence of methicillin-resistant Staphylococcus aureus (MRSA), explaining the limited response to the initial antibiotic regimen. The team swiftly adjusted the antibiotic therapy to include vancomycin, targeting this resistant organism specifically. Additionally, a complete metabolic panel revealed a mild increase in lactate levels, now at 2.8 mmol/L, further supporting the suspected systemic infection and highlighting the need for aggressive management to prevent progression to septic shock.

In response to these developments, the team prioritized stabilizing the patient's hemodynamic status. Intravenous fluids were administered to address the hypotension, and continuous monitoring of vital signs was implemented. The patient's fluid balance and organ function were closely observed to assess the effectiveness of the interventions and detect any signs of deterioration. The intensified wound care measures and revised antibiotic strategy aimed to contain the infection locally, while systemic support focused on preventing the escalation of sepsis. The interdisciplinary team remained vigilant, prepared to escalate care as needed, ensuring a comprehensive approach to the patient's complex clinical picture.

Section 4

As the healthcare team continued to address the patient's hemodynamic instability and systemic infection, they noted a concerning change in the patient's status. Despite the administration of intravenous fluids and adjusted antibiotic therapy, the patient developed new complications that required immediate attention. Over the next 12 hours, the patient's respiratory rate increased to 28 breaths per minute, and oxygen saturation levels dropped to 88% on room air, indicating potential respiratory compromise. Auscultation revealed diminished breath sounds in the lower lobes, raising suspicion for evolving pulmonary involvement.

A chest X-ray was promptly ordered and revealed bilateral infiltrates suggestive of early pneumonia, likely secondary to the systemic spread of the MRSA infection. This finding correlated with the patient's worsening respiratory status and prompted the addition of supplemental oxygen therapy to maintain adequate oxygenation. The team considered the possibility of acute respiratory distress syndrome (ARDS) given the rapid progression of respiratory symptoms in the context of sepsis.

In response to these developments, the interdisciplinary team expanded the patient's management plan. Alongside continued wound care and targeted antibiotic therapy, respiratory support became a priority. High-flow nasal cannula was initiated to improve oxygen delivery, and respiratory therapists were engaged to provide regular pulmonary hygiene and monitoring. The team also revisited the patient's fluid management, balancing the need for volume resuscitation with the risk of pulmonary edema, demonstrating the complex interplay of maintaining hemodynamic stability while managing emerging complications. These actions underscored the importance of dynamic clinical reasoning and adaptability in navigating the patient's evolving clinical picture.

Section 5

Despite the comprehensive management plan, the patient's condition continued to evolve with new complications emerging. Within 24 hours, the patient began to exhibit signs of acute renal impairment. Urine output decreased significantly to less than 0.5 mL/kg/hr, and laboratory results showed elevated serum creatinine and blood urea nitrogen, indicating acute kidney injury (AKI). This development raised concerns about the patient's fluid balance and the impact of both the systemic infection and medications on renal function. The team was tasked with re-evaluating the patient's fluid and medication management to prevent further renal compromise.

Simultaneously, the patient's skin integrity worsened. The existing pressure injury on the sacrum had become more pronounced, with increased erythema and exudate, despite regular repositioning and specialized wound care. This deterioration suggested a possible progression to a stage 3 pressure injury, necessitating a reassessment of the patient's nutritional status and support measures. Serum albumin levels were found to be low, indicating poor nutritional reserves, which compounded the risk of impaired healing and further pressure injury development.

Faced with these challenges, the healthcare team prioritized a multidisciplinary approach. Nephrology was consulted for guidance on managing the AKI while minimizing nephrotoxic risks. Nutrition support was enhanced with the introduction of high-protein supplements, and the wound care team adjusted the treatment regimen to include advanced dressings and negative pressure wound therapy. These interventions aimed to stabilize the patient's condition and highlighted the critical need for coordinated care and vigilant monitoring to address the interconnected complications effectively. This comprehensive strategy set the stage for ongoing assessment and adaptation in the patient's complex clinical course.
