Abstract:
Background: In COVID-19 patients non-invasive-positive-pressure-ventilation (NIPPV)
has held a challenging role to reduce mortality and the need for invasive mechanical ventilation
(IMV). The aim of this study was to compare the characteristics of patients admitted to a Medical
Intermediate Care Unit for acute respiratory failure due to SARS-CoV-2 pneumonia throughout four
pandemic waves. Methods: The clinical data of 300 COVID-19 patients treated with continuous
positive airway pressure (CPAP) were retrospectively analysed, from March-2020 to April-2022.
Results: Non-survivors were older and more comorbid, whereas patients transferred to ICU were
younger and had fewer pathologies. Patients were older (from 65 (29–91) years in I wave to 77 (32–94)
in IV, p < 0.001) and with more comorbidities (from Charlson’s Comorbidity Index = 3 (0–12) in I to
6 (1–12) in IV, p < 0.001). No statistical difference was found for in-hospital mortality (33.0%, 35.8%,
29.6% and 45.9% in I, II, III and IV, p = 0.216), although ICU-transfers rate decreased from 22.0% to
1.4%. Conclusions: COVID-19 patients have become progressively older and with more comorbidities
even in critical care area; from risk class analyses by age and comorbidity burden, in-hospital mortality
rates remain high and are thus consistent over four waves while ICU-transfers have significantly
reduced. Epidemiological changes need to be considered to improve the appropriateness of care.
