We sincerely appreciate the interest of Ferri et al. in our study and we are grateful for the valuable comments and feedback which have allowed us to respond with some clarifications [1] . The Letter to the Editor by Ferri et al. is merely focused on the timing of the tracheostomy, which actually is not the main aspect of the editorial letter by Mattioli et al. [2] . Ferri et al. suggested that tracheostomy should be performed in stable or clinically improved patients affected by Coronavirus Disease 2019 (COVID-19), not before the 20th day after orotracheal intubation. The authors support the "late tracheostomy protocol" thesis on 8 patients undergoing open tracheostomy declaring a negative prognostic trend for the subgroup of patients with shorter duration of intubation. We deem it inappropriate to draw conclusion with such a small cohort of patients and without any data and explanations regarding the reasons why an earlier tracheostomy would lead to worse survival.

Tracheostomy is one of the commonest surgical procedure in the setting of acute respiratory distress syndrome (ARDS) with need of prolonged invasive mechanical ventilation (IMV). Traditionally, tracheostomies are performed to improve patient comfort, to facilitate airway and pulmonary toilet, to ease weaning and to facilitate the management of these patients. Moreover, it decreases the risk of complications such as subglottic and tracheal stenosis, which will likely become a striking reality amongst COVID-19 survivors (Mattioli et al.-under review) . To date, one of the most convincing paper regarding this topic is the systematic review published by Adly et al. in 2018 [3] . The authors took into account 43 studies with a total number of 222,641 patients, showing that early tracheostomy (performed within 7 days from orotracheal intubation) reduces the clinical complications (i.e. aspiration pneumonia, bacteremia, septic shock, multi-organ failure), the mortality rate as well as the length of stay in intensive care unit (ICU).

Although delaying tracheostomy for patients with COVID-19 might reduce risks for staff, extended duration of translaryngeal intubation, sedation, IMV, and ICU stay associated with such delays can lead to complications [4] .

Moreover, an increased need for ICU admission due to COVID-19-related ARDS was a reality at the time of the publication of Mattioli et al. editor letter [2] . The magnitude of this demand caused an imbalance between the real clinical needs of the population and the effective availability of intensive resources. Thus, the tracheostomy represented an important measure for early ICU discharge to intermediate care ward for patients with ongoing IMV. Recovering patients who continue to require ventilatory support via a tracheostomy can be managed with minimal sedation, which might simplify care and facilitate transfer to lower-acuity facilities, thus creating capacity for more acute patients. In accordance with recent expert's guidelines [4] , we deem appropriate that standard decision making should be adapted for the COVID-19 pandemic, taking into account a range of considerations, including potential risks and benefits for the individual patient; risks posed to health-care workers, other patients, and family; and available health-care resources ( Table 1) . The timing of tracheostomy should consider patient's clinical improvement perspective, which can be weighted through the Sequential Organ Failure Assessment (SOFA) score, as already stated in our previous Letter to the Editor and also demonstrated by other authors [5] . Although it is not possible to define an optimal timing, it is our opinion that tracheostomy should be indicated on case-by-case basis taking into account including potential risks and benefits for the individual patient; risks posed to health-care workers and other patients; and available health-care resources. In addition, we still deem appropriate to limit, when possible, late tracheostomies to avoid potential further complications.
