Reducing Sternal Wound Infection Rates in Patients Undergoing Cardiothoracic Surgery with Sternotomy.

LOCAL PROBLEM: Sternal wound infections (SWIs), whether superficial or deep, are associated with increased morbidity, mortality, and costs. From 2016 to 2017, our facility saw a 50% decrease in SWIs among patients undergoing cardiothoracic surgery with sternotomy. From 2017 to 2018, however, we identified a 33% increase in SWIs, prompting us to address our cardiac nurses' sternal wound care education and practice. PURPOSE: The purpose of our quality improvement (QI) project was to identify opportunities for improvement in postoperative sternal incision care and to implement evidence-based processes to reduce the incidence of SWIs among cardiothoracic surgery patients. METHODS: A literature review was performed to identify interventions focused on evidence-based SWI reduction. During the first quarter of 2019, our postoperative incision care guidelines were revised and released to staff, a new surgical wound cleansing product was supplied, and RN education was provided. Cardiac nurses were surveyed in April 2019 to identify any remaining knowledge and practice deficits and to assess their adherence to the new guidelines. The survey responses helped us to further improve our nurse education. We also provided periodic nurse reeducation and enhanced patient and family education. All such interventions were implemented by the end of June 2019. RESULTS: Between January and June 2019, we had one SWI. From July 2019 through December 2020, an 18-month period, we experienced zero SWIs. Although beginning in 2021, we saw an increase in SWIs-four in 2021 and five in 2022-our incidence rates remain below 0.5% and we continue to work toward an SWI goal of zero. CONCLUSION: This QI project identified opportunities for improvement, implemented evidence-based strategies for wound care and education, and successfully achieved a zero SWI rate for a period of 18 months.

Evaluating the Effectiveness of an Alternating Pressure Overlay in Patients Undergoing Cardiothoracic Surgery.

LOCAL PROBLEM: In 2019 and the first half of 2020, our facility experienced an increase in the number and severity of hospital-acquired pressure injuries (HAPIs) among our cardiothoracic surgery population. Fifty percent of these HAPIs occurred within 72 hours of surgery. A review of the literature revealed that alternating pressure overlays (APOs) have been successfully used to prevent HAPIs in surgical patients. PURPOSE: The primary purpose of our quality improvement (QI) project was to measure perioperative HAPI rates in cardiothoracic surgery patients after the addition of APOs to our HAPI prevention protocol. Our secondary purpose was to identify common factors among those patients who developed HAPIs. METHODS: This QI project collected both pre- and postintervention data and compared the findings. A nurse-led team was responsible for measuring HAPI rates during the intervention-from July through October 2020-which involved placing an APO under cardiothoracic surgery patients during the 72-hour perioperative period. APOs were placed on all operating room (OR) tables and remained with the patients following surgery. Bed linens and skin care products were standardized for consistency. Lifts were used to reduce friction during repositioning. RESULTS: During preintervention data collection, we identified 10 patients who developed HAPIs (seven out of 1,174 cardiothoracic surgery patients in 2019, for a HAPI rate of 0.6%, and three out of 333 patients in the first half of 2020, for a HAPI rate of 0.9%). During the four-month intervention period, in which APOs were used in 331 patients undergoing cardiothoracic surgery, no HAPIs developed. CONCLUSION: Use of an APO in cardiothoracic ORs and critical care units may help reduce HAPI rates.
