Summary
A new multi-disciplinary care bundle significantly reduced post-sternotomy mediastinitis (PSM) incidence in cardiac surgery patients. This structured post-discharge care, including wound surveillance, is vital for patient outcomes.
Area of Science:
- Cardiology
- Surgical Outcomes
- Infection Control
Background:
- Post-sternotomy mediastinitis (PSM) is a severe complication following cardiac surgery.
- The incidence and management of PSM require effective interventions.
Purpose of the Study:
- To evaluate the impact of a structured multi-disciplinary post-discharge care bundle on PSM incidence.
- To assess the effectiveness of enhanced wound surveillance in reducing PSM rates.
Main Methods:
- Retrospective cohort study comparing PSM incidence pre- and post-care bundle implementation.
- Care bundle included telephonic monitoring, specialized wound clinic, and negative pressure wound therapy.
- Statistical analysis used chi-square tests, logistic regression with propensity score weighting, and linear regression.
Main Results:
- Crude PSM incidence decreased from 3.32% to 1.56% post-implementation.
- Adjusted analysis showed a significant 59% relative reduction in PSM rate (p=0.044).
- No significant time trend was observed in newly identified wound infections.
Conclusions:
- A multi-disciplinary care bundle significantly reduces PSM incidence in cardiac sternotomy patients.
- Structured outpatient wound surveillance is crucial for improving surgical outcomes.
- The findings support the integration of comprehensive care bundles in post-cardiac surgery management.

01:28Cardiomyopathy VII: Pre and Post Operative Nursing Management
405
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
