Dear Editor-in-chief,
We read with great interest the manuscript by Losurdo et al. that reported a reduced rate of surgical site infections (SSIs) during the COVID-19 pandemic as compared with previous years, possibly in relation to the implementation of hygienic measures and the systematic use of personal protective equipment (PPE) among healthcare workers and patients [1].
In a recent paper published by our group, we investigated whether the increase in hygienic measures during the pandemic determined a decrease in hospital-acquired infections (HAIs) as compared with the previous year [2]. The study was conducted in a COVID-free unit to avoid the possible confounding impact of a COVID-19 coinfection. After adjusting for other variables, we found a significant decrease in HAIs and antibiotic prescriptions in our unit, which we think was largely attributable to the huge increase in hygienic measures.
Similarly, Ponce-Alonso et al. recently found an almost 70% reduction in Clostridioides difficile infections in a tertiary-care hospital in Spain during the COVID-19 outbreak [3]. These authors also ascribed this reduction to the stricter hygienic measures adopted during the recent pandemic.
In light of these findings, we strongly believe that a serious debate regarding the need to extend the reinforcement of infection prevention and control (including the systematic use of PPE) beyond the COVID-19 pandemic, is particularly urgent. Indeed, the high burden of HAIs in terms of mortality and public spending is well known and has been highlighted by multiple reports published by EU agencies [4]. Among HAIs, SSIs represent the most common infection in low-income countries, and one of the most frequent in high-income countries [4]. When considering the EU and USA together, an estimated 140,000 deaths are directly attributable to HAIs [5]. Moreover, it is well known that HAIs also contribute to other deaths, perhaps as many as 110,000 in the EU alone [5].
Despite countless calls for action by international agencies during the last years to improve programs for infection prevention and control worldwide [4], these calls have largely been unheeded, and a rapid improvement in the implementation of these programs seemed unlikely. However, the recent COVID-19 pandemic has clearly taught us a lesson: in the midst of a health emergency, the majority of developed countries succeeded in rapidly planning and implementing more efficient hygiene protocols in their hospitals.
It would be a huge mistake to waste the opportunity offered by COVID-19 to finally take a step forward in improving infection prevention and control.
