Two-months quality of life of COVID-19 invasively ventilated survivors; an Italian single-center study.

BACKGROUND: COVID-19 disease can lead to severe functional impairments after discharge. We assessed the quality of life of invasively ventilated COVID-19 ARDS survivors. METHODS: We carried out a prospective follow-up study of the patients admitted to the Intensive Care Units (ICUs) of a teaching hospital. Patients affected by COVID-19 ARDS who required invasive ventilation and were successfully discharged home were assessed through the telephone administration of validated tests. We explored survival, functional outcomes, return to work, quality of life, cognitive and psychological sequelae. The main variables of interest were the following: demographics, severity scores, laboratory values, comorbidities, schooling, working status, treatments received during ICU stay, complications, and psychological, cognitive, functional outcomes. RESULTS: Out of 116 consecutive invasively ventilated patients, overall survival was 65/116 (56%) with no death occurring after hospital discharge. Forty-two patients were already discharged home with a median follow-up time of 61 (51-71) days after ICU discharge and 39 of them accepted to be interviewed. Only one patient (1/39) experienced cognitive decline. The vast majority of patients reported no difficulty in walking (32/35:82%), self-care (33/39:85%), and usual activities (30/39:78%). All patients were either malnourished (15/39:38%) or at risk for malnutrition (24/39:62%). Exertional dyspnea was present in 20/39 (51%) patients. 19/39 (49%) reported alterations in senses of smell and/or taste either before or after hospitalization. CONCLUSIONS: Invasively ventilated COVID-19 ARDS survivors have an overall good recovery at a 2-months follow-up which is better than what was previously reported in non-COVID-19 ARDS patients.

Feasibility, safety and efficacy of COVID-19 severe acute respiratory distress syndrome management without invasive mechanical ventilation.

BACKGROUND: COVID-19 acute respiratory distress syndrome (ARDS) is often managed with mechanical ventilation (MV), requiring sedation and paralysis, with associated risk of complications. There is limited evidence on the use of high flow nasal cannula (HFNC). We hypothesized that management of COVID-19 ARDS without MV is feasible. METHODS: Included were all adult patients diagnosed with COVID-19 ARDS, with PaO2/FiO2 ratio <100 at admission, and whose management was initially performed without MV. We evaluated need for intubation during ICU stay, mortality and hospital/ICU length of stay (LOS). RESULTS: Out of 118 patients, 41 were managed only with HFNC from hospital admission (and at least during first 24 hours in ICU) and had a PaO2/FiO2 ratio <100 (72.9±13.0). Twenty-nine out of 41 patients never required MV: 24 of them survived and were discharged home. Their median ICU LOS was 11 (7-17) days, and their hospital LOS was 29 (18-45) days. We identified PaO2/FiO2 ratio at ICU admission as the only significant predictor for need for MV during ICU stay. We also identified age, length of non-invasive respiratory support before ICU admission, mean value of PaO2/FiO2 ratio during first half and whole ICU stay as predictors of mortality. CONCLUSIONS: It is safe to monitor in ICU and use HFNC in patients affected by COVID-19 ARDS who initially present data suggesting an early need for intubation. The 41 patients admitted with a PaO2/FiO2 ratio <100 and initially treated only with HFNC show a 22% mortality that is in the lower range of what is reported in recent literature.

COVID-19 second wave: appropriateness of admissions to the Emergency Department of a main metropolitan hospital in Milan.

BACKGROUND: In Europe, Italy and Lombardy, in autumn 2020, there was a steep increase in reported cases due to the second epidemic wave of SARS-Cov-2 infection. We aimed to evaluate the appropriateness of COVID-19 patients' admissions to the ED of the San Raffaele Hospital. METHODS: We compared data between the inter-wave period (IWP, from 1st to 30th September) and the second wave period (WP, 1st October to 15th November) focusing on the ED presentation, discharge priority colour code and outcomes. RESULTS: Out of 977 admissions with a SARS-Cov-2 positive swab, 6% were in the IWP and 94% in the WP. Red, yellow and white code increased (these latter from 1.8% to 5.4%) as well as self-presented in yellow and white code. Discharges home increased from 1.8% to 5.4%, while hospitalizations decreased from 63% to 51%. DISCUSSION: We found a rise in white codes (among self-presented patients), indicating inappropriateness of admissions. The increase in discharges suggests that several patients did not require hospitalization. CONCLUSIONS: The pandemic brought out the fundamental role of primary care to manage patients with low-intensity needs. The important increase in ED admissions of COVID-19 patients caused a reduction of NO-COVID-19 patients, with possible inadequate treatment.

Continuous infusion versus intermittent administration of meropenem in critically ill patients (MERCY): A multicenter randomized double-blind trial. Rationale and design.

OBJECTIVE: Meropenem is a ß-lactam, carbapenem antibacterial agent with antimicrobial activity against gram-negative, gram-positive and anaerobic micro-organisms and is important in the empirical treatment of serious infections in Intensive Care Unit (ICU) patients. Multi-drug resistant gram-negative organisms, coupled with scarcity of new antibiotic classes, forced healthcare community to optimize the therapeutic potential of available antibiotics. Our aim is to investigate the effect of continuous infusion of meropenem against bolus administration, as indicated by a composite outcome of reducing death and emergence of extensive or pan drug-resistant pathogens in a population of ICU patients. DESIGN: Double blind, double dummy, multicenter randomized controlled trial (1:1 allocation ratio). SETTING: Tertiary and University hospitals. INTERVENTIONS: 600 ICU patients with sepsis or septic shock, needing by clinical judgment antibiotic therapy with meropenem, will be randomized to receive a continuous infusion of meropenem 3 g/24 h or an equal dose divided into three daily boluses (i.e. 1g q8h). MEASUREMENTS: The primary endpoint will be a composite outcome of reducing death and emergence of extensive or pan drug-resistant pathogens. Secondary endpoints will be death from any cause at day 90, antibiotic-free days at day 28, ICU-free days at day 28, cumulative SOFA-free (Sequential Organ Failure Assessment) score from randomization to day 28 and the two, separate, components of the primary endpoint. We expect a primary outcome reduction from 52 to 40% in the continuous infusion group. CONCLUSIONS: The trial will provide evidence for choosing intermittent or continuous infusion of meropenem for critically ill patients with multi-drug resistant gram-negative infections.
