Results of a postoperative telemedicine trial after cardiac surgery and incorporation into practice.

Objective: The study objective was to describe the implementation and results of a postoperative telemedicine program for adult cardiac surgery, including a clinical study and an organic postoperative telemedicine program aimed at reducing readmission rates and barriers to care. Methods: Patients undergoing coronary artery bypass grafting consented to enrollment in our Perfect Care study funded by The Duke Endowment including advanced practice provider-led postdischarge telemedicine services with data collection. There were 2 telemedicine visits at days 3 and 10 postdischarge using a live face-to-face video platform. Patients were provided with home wearables for heart rate monitoring, blood pressure cuffs, and scales. The success of the Perfect Care study led to the formation of our organic program, the Tele Heart Care, which was adapted to include a larger patient population while remaining structurally similar. Results: Fifty patients were enrolled prospectively between January and October 2021 in Perfect Care. The 30-day readmission rates for those enrolled was 4% compared with a 16% readmission rate for nonenrolled patients during this period. Furthermore, 36% of enrolled patients received medication modifications to optimize blood pressure, heart rate and rhythm, and fluid-volume status, or to treat infectious symptoms. Tele Heart Care enrolled 203 patients and was associated with a decrease in 30-day readmission rates in all cardiac surgery patients at our institution from 24% to 4% over a 6-month period. Conclusions: An advanced practice provider-led postdischarge telemedicine program after cardiac surgery can reduce hospital readmission and barriers to care, and improve patient satisfaction. With involvement of multiple stakeholders, a successful program can be launched despite the present state of national health system finances with limited human capital and constrained access to monitoring equipment.

Eliminating sternal wound infections: Why every cardiac surgery program needs an I hate infections team.

Objectives: The majority of studies examining deep sternal wound infection (DSWI) prevention focus on ameliorating 1 variable at a time. There is a paucity of data regarding the synergistic effects of combining clinical and environmental interventions. This article describes an interdisciplinary, multimodal approach to eliminate DSWIs at a large community hospital. Methods: We developed a robust, multidisciplinary infection prevention team to evaluate and act in all phases of perioperative care to achieve a cardiac surgery DSWI rate of 0, named: the I hate infections team. The team identified opportunities for improved care and best practices and implemented changes on an ongoing basis. Results: Patient-related interventions consisted of preoperative methicillin-resistant Staphylococcus aureus identification, individualized perioperative antibiotics, antimicrobial dosing strategies, and maintenance of normothermia. Operative-related interventions involved glycemic control, sternal adhesives, medications and hemostasis, rigid sternal fixation for high-risk patients, chlorhexidine gluconate dressings over invasive lines, and use of disposable health care equipment. Environment-related interventions included optimizing operating room ventilation and terminal cleaning, reducing airborne particle counts, and decreasing foot traffic. Together, these interventions reduced the DSWI incidence from 1.6% preintervention to 0% for 12 consecutive months after full bundle implementation. Conclusions: A multidisciplinary team focused on eliminating DSWI identified known risk factors and implemented evidence-based interventions in each phase of care to ameliorate risk. Although the influence of each individual intervention on DSWI remains unknown, use of the bundled infection prevention approach reduced the incidence to 0 for the first 12 months after implementation.

Silver-Impregnated Dressing Does Not Decrease Incidence of Surgical Site Infection After Adult Cardiac Surgery.

OBJECTIVE: Sternal wound infections complicate 1% to 8% of cardiac surgeries and carry significant morbidity. We investigated the utility of silver-impregnated dressing in decreasing sternal wound infections after sternotomy cases. METHODS: A single-institution cohort study was performed as part of a quality improvement trial of a new sternal dressing. Five hundred fifty-seven sternotomy cases were performed in 2015 with application of a traditional gauze dressing. In 2016, 682 sternotomy cases were performed with the use of a commercially available silver-impregnated dressing. Prospectively identified metrics were analyzed for each patient population along with nursing assessments and structured questionnaires. RESULTS: Baseline characteristics of patients in traditional gauze and silver-impregnated dressing groups were similar. Morbidity and mortality were similar. Nine (1.6%) and 12 (1.8%) sternal wound infections were reported in traditional gauze and silver-impregnated dressing groups, respectively. There was no difference in the rate of sternal wound infections (P = 0.80). The number of organ space infections (3) and deep sternal wound infections (3) was the same; however, the number of superficial infections was greater in the silver-impregnated dressing cohort (3 vs. 6). Among patients in either group with sternal wound infection, there were no differences in the proportion of superficial infections (44% vs. 50%, P = 0.8) or the organism cultured (67% vs. 50% staphylococcus, P = 0.45). A total of 22% of patients reported "not satisfied" with silver-impregnated dressing. CONCLUSIONS: Silver dressings did not reduce sternal wound infection after sternotomy for cardiac surgery in a large-cohort study. We discontinued the routine use of silver dressings for adult cardiac surgery based on these results because traditional gauze likely represents an equally effective and less costly alternative.
