ABSTRACT
Introduction Healthcare systems suffered a significant hit by the COVID-19 pandemic since the spring of 2020, and a need for major reorganization emerged. Along with the constant increase in COVID-19 cases, a significant drop in emergency attendances for non-COVID-19-related conditions was noted worldwide. We decided to document attendances in our hospital's emergency department during the first lockdown period in order to monitor this trend, compare it to data from other countries, and start monitoring the effects of this reduction in the years to come. Materials and methods Emergency department attendances at AHEPA University Hospital, Thessaloniki, Greece, from March 10, 2020, to May 31, 2020, were documented and compared to the corresponding period in 2019. The data collected included the number of patients per specialty, severity upon admission, as well as the need for admission. Results We found a 58% reduction in emergency department attendance during the studied period compared to the corresponding period in 2019 (p<0.0001). The reduction was more noticeable in ears, nose, throat (ENT), and ophthalmology attendances (75.7% and 78.1% reductions, respectively, p<0.001), but other specialties, such as cardiology and general surgery, were also significantly affected (60% and 63% reductions, respectively, p<0.001). However, the percentage of attendances that required admission increased significantly by 25-33% (p<0.001) during the lockdown, reflecting the higher severity of cases reaching the hospital. Conclusion Despite the obvious reduction in attendances during the COVID-19 pandemic, patients still suffer from serious conditions that require hospital admission. Therefore, hospitals need to be supported to also care for these patients. The long-term effects of avoiding hospital attendance need to be closely monitored.
ABSTRACT
The role of probiotics in the prevention of ventilator-associated pneumonia (VAP) remains inconclusive. The aim of this study was to assess the efficacy of a probiotic regimen for VAP prophylaxis in mechanically ventilated multi-trauma patients, intubated immediately after the injurious insult. In a randomized, placebo-controlled study enrolling multi-trauma patients, patients expected to require mechanical ventilation for >10 days were assigned at random to receive prophylaxis with a probiotic formula (n=59) or placebo (n=53). The probiotic formula was a preparation of Lactobacillus acidophilus LA-5 [1.75 × 109 colony-forming units (cfu)], Lactobacillus plantarum (0.5 × 109 cfu), Bifidobacterium lactis BB-12 (1.75 × 109 cfu) and Saccharomyces boulardii (1.5 × 109 cfu) in sachets. Each patient received two sachets twice daily for 15 days: one through the nasogastric tube and one spread on the oropharynx. The incidence of VAP was the primary endpoint. The incidence of other infections and sepsis, and the duration of hospital stay were the secondary endpoints. Administration of probiotics reduced the incidence of VAP [11.9% vs 28.3%, hazard ratio (HR) 0.34, 95% confidence interval (CI) 0.13-0.92; P=0.034] and sepsis [6.8% vs 24.5%, odds ratio 0.22, 95% CI 0.07-0.74: P=0.016]. Furthermore, probiotic prophylaxis reduced the time of stay in the intensive care unit (ICU) and the length of hospital stay. The prophylactic use of probiotics with a combination of enteral and topical application to the oropharynx had a positive effect on the incidence of VAP and sepsis, as well as on ICU and total hospital stay in patients receiving protracted mechanical ventilation.
