Health Care-Associated Infections: Best Practices for Prevention

Health care-associated infections (HAIs) are a significant cause of morbidity and mortality in the United States. Common examples include catheter-associated urinary tract infections, central line-associated bloodstream infections, ventilator-associated pneumonia, surgical site infections, and Clostridioides difficile infections. Standardized infection control processes and precautions have been shown to reduce the rate of HAIs, and targeted practices for HAIs have shown further reductions. Patient safety tools have been developed for various HAIs to help guide administrators and are free for public use through the Centers for Disease Control and Prevention STRIVE (States Targeting Reduction in Infections via Engagement) initiative. The Choosing Wisely initiative makes best practice recommendations for physicians to improve quality of care and reduce costs;targeted recommendations were developed to reduce the risk of HAIs. For example, using invasive devices only when indicated and for the shortest time possible reduces the risk of device-related HAIs. The goal of antibiotic stewardship is to reduce C. difficile infections and further development of multidrug-resistant organisms such as vancomycin-resistant Enterococcus and carbapenem-resistant Enterobacteriaceae. Antibiotic stewardship targets physician behaviors such as reviewing antibiotic therapy choices every 48 to 72 hours, reviewing culture results as soon as available, de-escalating antibiotic therapy when appropriate, and documenting the indications for initiating and continuing antibiotic therapy.Copyright © 2022 American Academy of Family Physicians.

Multiple-site decontamination regimen decreases acquired infection incidence in mechanically ventilated COVID-19 patients.

BACKGROUND: Among strategies that aimed to prevent acquired infections (AIs), selective decontamination regimens have been poorly studied in the COVID-19 setting. We assessed the impact of a multiple-site decontamination (MSD) regimen on the incidence of bloodstream infections (BSI) and ventilator-associated pneumonia (VAP) in COVID-19 patients receiving mechanical ventilation. METHODS: We performed an ancillary analysis of a multicenter retrospective observational study in 15 ICUs in western France. In addition to standard-care (SC), 3 ICUs used MSD, a variant of selective digestive decontamination, which consists of the administration of topical antibiotics four times daily in the oropharynx and the gastric tube, chlorhexidine body wash and a 5-day nasal mupirocin course. AIs were compared between the 3 ICUs using MSD (MSD group) and the 12 ICUs using SC. RESULTS: During study period, 614 of 1158 COVID-19 patients admitted in our ICU were intubated for at least 48 h. Due to missing data in 153 patients, 461 patients were finally included of whom 89 received MSD. There were 34 AIs in the MSD group (2117 patient-days), as compared with 274 AIs in the SC group (8957 patient-days) (p < 0.001). MSD was independently associated with a lower risk of AI (IRR = 0.56 [0.38-0.83]; p = 0.004) (Table 2). When the same model was used for each site of infection, MSD remained independently associated with a lower risk of VAP (IRR = 0.52 [0.33-0.89]; p = 0.005) but not of BSI (IRR = 0.58, [0.25-1.34], p = 0.21). Hospital mortality was lower in the MSD group (16.9% vs 30.1%, p = 0.017). CONCLUSIONS: In ventilated COVID-19 patients, MSD was independently associated with lower AI incidence.

SYSTEMIC IMMUNOMODULATING THERAPIES FOR STEVENS-JOHNSON SYNDROME AND TOXIC EPIDERMAL NECROLYSIS IN A COVID-19 PATIENT. A CASE REPORT

Stevens-Johnson syndrome and toxic epidermal necrolysis are rare serious disorders that affect the skin and mucous membranes. These reactions are most commonly caused by drugs and, rarely, infections. While discontinuing the offending drug and supportive care are primordial, there are no consensus treatment guidelines on the optimal use of systemic immunomodulatory agents. Here, we report a case of a 57-year-old woman, who had recently recovered from COVID-19 infection, with Stevens-Johnson syndrome/toxic epidermal necrolysis overlap most likely triggered by dorzolamide eye drops. The patient was successfully treated with a single subcutaneous dose of etanercept combined with oral cyclosporine, corticosteroids and intravenous immunoglobulins. The progression of skin lesions ceased after administration of etanercept. In addition, a significant clinical improvement was observed a few days after treatment with immunoglobulins, without complications or important side effects.
