Positive end-expiratory pressure (PEEP) is a key element of mechanical ventilation. It should optimize recruitment, without causing excessive overdistension, but controversy exists on the best method to set it. The purpose of the study was to test the feasibility of setting PEEP with electrical impedance tomography in order to prevent lung de-recruitment following a recruitment maneuver. We enrolled 16 patients undergoing mechanical ventilation with PaO2/FiO2 <300 mmHg. In all patients, under constant tidal volume (6–8 ml/kg) PEEP was set based on the PEEP/FiO2 table proposed by the ARDS network (PEEPARDSnet). We performed a recruitment maneuver and monitored the end-expiratory lung impedance (EELI) over 10 min. If the EELI signal decreased during this period, the recruitment maneuver was repeated and PEEP increased by 2 cmH2O. This procedure was repeated until the EELI maintained a stability over time (PEEPEIT). The procedure was feasible in 87% patients. PEEPEIT was higher than PEEPARDSnet (13 ± 3 vs. 9 ± 2 cmH2O, p < 0.001). PaO2/FiO2 improved during PEEPEIT and driving pressure decreased. Recruited volume correlated with the decrease in driving pressure but not with oxygenation improvement. Finally, regional alveolar hyperdistention and collapse was reduced in dependent lung layers and increased in non-dependent lung layers. In hypoxemic patients, a PEEP selection strategy aimed at stabilizing alveolar recruitment guided by EIT at the bedside was feasible and safe. This strategy led, in comparison with the ARDSnet table, to higher PEEP, improved oxygenation and reduced driving pressure, allowing to estimate the relative weight of overdistension and recruitment.

To determine the prevalence of complications in patients with COVID-19 undergone prone positioning, focusing on the development of prone-related pressure ulcers. Cross-sectional study conducted in the hub COVID-19 centre in Milan (Italy), between March and June 2020. All patients with COVID-19 admitted to intensive care unit on invasive mechanical ventilation and treated with prone positioning were included. Association between prone-related pressure ulcers and selected variables was explored by the means of logistic regression. A total of 219 proning cycles were performed on 63 patients, aged 57.6 (10.8) and predominantly obese males (66.7%). The main complications recorded were: prone-related pressure ulcers (30.2%), bleeding (25.4%) and medical device displacement (12.7%), even if no unplanned extubation was recorded. The majority of patients (17.5%) experienced bleeding of upper airways. Only 15 prone positioning cycles (6.8%) were interrupted, requiring staff to roll the patient back in the supine position. The likelihood of pressure ulcers development was independently associated with the duration of prone positioning, once adjusting for age, hypoxemic level, and nutritional status (OR 1.9, 95%CI 1.04–3.6). The use of prone positioning in patients with COVID-19 was a safe and feasible treatment, also in obese patients, who might deserve more surveillance and active prevention by intensive care unit staff.
At the height of the coronavirus disease 2019 (COVID-19) pandemic, Italy had the highest number of deaths in Europe; most occurred in the Lombardy region. Up to 4% of patients with COVID-19 required admission to an intensive care unit because they developed a critical illness (eg, acute respiratory distress syndrome). Numerous patients with acute respiratory distress syndrome who had been admitted to the intensive care unit required rescue therapy like prone positioning. To describe the respiratory management of and the extensive use of prone positioning in patients with COVID-19 at the intensive care unit hub in Lombardy, Italy. A total of 89 patients (67% male; median age, 59 years [range, 23-80 years]) with confirmed COVID-19 who were admitted between February 23 and March 31, 2020, were enrolled in this quality improvement project. Endotracheal intubation was required in 86 patients (97%). Prone positioning was used as rescue therapy in 43 (48%) patients. Significantly more younger patients (age ≤ 59 years) were discharged alive (43 of 48 [90%]) than were older patients (age ≥ 60 years; 26 of 41 [63%]; P < .005). Among the 43 patients treated with prone ventilation, 15 (35% [95% CI, 21%-51%]) died in the intensive care unit, of which 10 (67%; P < .001) were older patients. Prone positioning is one strategy available for treating acute respiratory distress syndrome in patients with COVID-19. During this pandemic, prone positioning can be used extensively as rescue therapy, per a specific protocol, in intensive care units.

To explore recurrent themes in diaries kept by intensive care unit (ICU) staff during the coronavirus disease 2019 (COVID-19) pandemic. Qualitative study. Two ICUs in a tertiary level hospital (Milan, Italy) from January to December 2021. ICU staff members wrote a digital diary while caring for adult patients hospitalized in the intensive care unit for >48 hours. A thematic analysis was performed. Diary entries described what happened and expressed emotions. Thematic analysis of 518 entries gleaned from 48 diaries identified four themes (plus ten subthemes): Presenting (Places and people; Diary project), Intensive Care Unit Stay (Clinical events; What the patient does; Patient support), Outside the Hospital (Family and topical events; The weather), Feelings and Thoughts (Encouragement and wishes; Farewell; Considerations). The themes were similar to published findings. They offer insight into care in an intensive care unit during a pandemic, with scarce resources and no family visitors permitted, reflecting on the patient as a person and on daily care. The staff wrote farewell entries to dying patients even though no one would read them. The implementation of digital diaries kept by intensive care unit staff is feasible even during the COVID-19 pandemic. Diaries kept by staff can provide a tool to humanize critical care. Staff can improve their work by reflecting on diary records.
Background/Objectives: Hospital bed shortage is a widespread issue affecting healthcare systems globally, often exacerbated by bed-blocking, a phenomenon where patients remain hospitalized longer than medically necessary due to discharge delays. The aim of this study was to evaluate the prevalence of patients with bed-blocker status admitted to the internal medicine wards. Methods: This cross-sectional study was conducted at an academic tertiary-level hospital in Milan (Italy) from 1 January to 31 December 2023. All adult patients identified as ready for discharge by the bed management service, but whose actual discharge was delayed by more than 24 h, were included. Clinical data were retrieved from electronic medical and nursing records. This study adhered to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. Results: Out of 2480 admissions to the internal medicine wards, 147 patients (5.9%) experienced delayed discharge. The median hospital length of stay was 22 days (IQR: 15.0–33.0); the median duration of appropriate stay was 6 days (IQR: 2.0–13.0), and the median length of delayed stay was 14 days (IQR: 7.0–21.0). Waiting for transfer to lower-intensity care facilities was the primary cause of delayed discharge. Complications during delayed stays included delirium (31.3%) and hospital-acquired infections (35.4%), particularly urinary tract infections (17.7%). Logistic regression identified older age (≥75 years), extended hospital length of stay, emergency admissions, and discharge to long-term care as independent predictors of bed-blocker status. Conclusions: This study highlights delayed discharges as a significant issue in internal medicine wards, driven by advanced age, caregiver absence, and high dependency in activities of daily living.
