Haemoptysis in adults: a 5-year study using the French nationwide hospital administrative database.

Haemoptysis is a serious symptom with various aetiologies. Our aim was to define the aetiologies, outcomes and associations with lung cancer in the entire population of a high-income country.This retrospective multicentre study was based on the French nationwide hospital medical information database collected over 5 years (2008-2012). We analysed haemoptysis incidence, aetiologies, geographical and seasonal distribution and mortality. We studied recurrence, association with lung cancer and mortality in a 3-year follow-up analysis.Each year, ~15 000 adult patients (mean age 62 years, male/female ratio 2/1) were admitted for haemoptysis or had haemoptysis as a complication of their hospital stay, representing 0.2% of all hospitalised patients. Haemoptysis was cryptogenic in 50% of cases. The main aetiologies were respiratory infections (22%), lung cancer (17.4%), bronchiectasis (6.8%), pulmonary oedema (4.2%), anticoagulants (3.5%), tuberculosis (2.7%), pulmonary embolism (2.6%) and aspergillosis (1.1%). Among incident cases, the 3-year recurrence rate was 16.3%. Of the initial cryptogenic haemoptysis patients, 4% were diagnosed with lung cancer within 3 years. Mortality rates during the first stay and at 1 and 3 years were 9.2%, 21.6% and 27%, respectively.This is the first epidemiological study analysing haemoptysis and its outcomes in an entire population. Haemoptysis is a life-threatening symptom unveiling potentially life-threatening underlying conditions.

Residual upper airway obstruction during nocturnal noninvasive ventilation despite high positive expiratory pressure. Impact of oronasal mask to nasal mask switch.

BACKGROUND: Nasal mask (NM) and oronasal masks (OM) can be used to provide noninvasive ventilation (NIV). Recent studies suggested that OM is the most used interface and that there is no difference in efficacy or in tolerance between OM and NM for chronic use. However, studies focusing on video laryngoscopy underlined the impact of OM in residual upper airway obstruction (UAO) under NIV. We sought to assess the real-life practice of switching from OM to NM when UAO events persist despite high EPAP levels. METHODS: In an open-label single center prospective cohort study, data from files and full night polysomnography on NM and OM were collected for patients wearing OM and presenting an UAO index ≥15/h despite an EPAP level ≥ 10 cmH20. RESULTS: Forty-four patients were included in the study. In 31 patients (74 %), switching to a NM reduced UAOi to ≥10/h. Interestingly, 92 % of these patients still had NM at 3 to 12 months of follow-up. Switching to a NM was also associated with a trend in paCO2 reduction and significant improvements in Epworth, sleep quality and NIV compliance. Successful interface switching was significantly associated with female gender, and a trend was observed in non-smokers. CONCLUSION: As for CPAP, switching to a NM improved NIV efficacy in a selected group of patients presenting residual UAO events despite high EPAP levels. Additionally, this switch has an impact on compliance and subjective sleepiness. Thus, in patients with persisting UAO on OM, switching to a NM could be a first-line intervention before considering further investigation such as polygraphy or video laryngoscopy. We also derive an algorithm for mask allocation and adaptation in acute and chronic NIV use.

Criteria deemed important by ICU patients when designating a reference person.

Background: We investigated the criteria that hospitalized patients in intensive care units (ICUs) deem important when designating relatives who are best qualified to interact with the caregiving staff. Methods: We conducted an exploratory, observational, prospective, multicenter study between March 1, 2018, and October 31, 2018, within two ICUs. A 12-item questionnaire was distributed to patients in the ICUs by the investigating physicians. Patients were considered eligible if they had a good understanding of the French language and if they had not officially designated surrogates before ICU admission. Results: Seventy-one patients whose average age was 63.9± 17.3 years, of whom 21 (29.5%) were females, completed the questionnaire. The average Charlson comorbidity score was 2.5 ± 2.4, and the average Simplified Acute Physiology Score (SAPS II) was 39.8 ± 16.5. The main etiology was respiratory infection (40.8%), followed by sepsis (23.9%). The most important criteria identified by patients when selecting reference persons were a good knowledge of the patient's wishes and values, an emotional attachment to the patient, and being a family member. Conclusion: Our findings reveal that ICU patients considered the following criteria to be critical when designating reference persons: knowledge of their wishes and the existence of emotional and family attachments.

Endotracheal tube biofilm in critically ill patients during the COVID-19 pandemic : description of an underestimated microbiological compartment.

Biofilm (BF) growth is believed to play a major role in the development of ventilator-associated pneumonia (VAP) in the intensive care unit. Despite concerted efforts to understand the potential implication of endotracheal tube (ETT)-BF dispersal, clinically relevant data are lacking to better characterize the impact of its mesostructure and microbiological singularity on the occurrence of VAP. We conducted a multicenter, retrospective observational study during the third wave of the COVID-19 pandemic, between March and May 2021. In total, 64 ETTs collected from 61 patients were included in the present BIOPAVIR study. Confocal microscopy acquisitions revealed two main morphological aspects of ETT-deposited BF: (1) a thin, continuous ribbon-shaped aspect, less likely monobacterial and predominantly associated with Enterobacter spp., Streptococcus pneumoniae or Viridans streptococci, and (2) a thicker, discontinuous, mushroom-shaped appearance, more likely characterized by the association of bacterial and fungal species in respiratory samples. The microbiological characterization of ETT-deposited BF found higher acquired resistance in more than 80% of analyzed BF phenotypes, compared to other colonization sites from the patient's environment. These findings reveal BF as a singular microbiological compartment, and are of added clinical value, with a view to future ETT-deposited BF-based antimicrobial stewardship in critically ill patients. Trial registration NCT04926493. Retrospectively registered 15 June 2021.

Mental health and stress among ICU healthcare professionals in France according to intensity of the COVID-19 epidemic.

BACKGROUND: We investigated the impact of the COVID-19 crisis on mental health of professionals working in the intensive care unit (ICU) according to the intensity of the epidemic in France. METHODS: This cross-sectional survey was conducted in 77 French hospitals from April 22 to May 13 2020. All ICU frontline healthcare workers were eligible. The primary endpoint was the mental health, assessed using the 12-item General Health Questionnaire. Sources of stress during the crisis were assessed using the Perceived Stressors in Intensive Care Units (PS-ICU) scale. Epidemic intensity was defined as high or low for each region based on publicly available data from Santé Publique France. Effects were assessed using linear mixed models, moderation and mediation analyses. RESULTS: In total, 2643 health professionals participated; 64.36% in high-intensity zones. Professionals in areas with greater epidemic intensity were at higher risk of mental health issues (p < 0.001), and higher levels of overall perceived stress (p < 0.001), compared to low-intensity zones. Factors associated with higher overall perceived stress were female sex (B = 0.13; 95% confidence interval [CI] = 0.08-0.17), having a relative at risk of COVID-19 (B = 0.14; 95%-CI = 0.09-0.18) and working in high-intensity zones (B = 0.11; 95%-CI = 0.02-0.20). Perceived stress mediated the impact of the crisis context on mental health (B = 0.23, 95%-CI = 0.05, 0.41) and the impact of stress on mental health was moderated by positive thinking, b = - 0.32, 95% CI = - 0.54, - 0.11. CONCLUSION: COVID-19 negatively impacted the mental health of ICU professionals. Professionals working in zones where the epidemic was of high intensity were significantly more affected, with higher levels of perceived stress. This study is supported by a grant from the French Ministry of Health (PHRC-COVID 2020).

Criteria deemed important by the relatives for designating a reference person for patients hospitalized in ICU.

PURPOSE: We investigated the criteria that patients' relatives deem important for choosing, among themselves, the person best qualified to interact with the caregiving staff. METHODS: Exploratory, observational, prospective, multicentre study between 1st March and 31st October 2018 in 2 intensive care units (ICUs). A 12-item questionnaire was completed anonymously by family members of patients hospitalized in the ICU 3 and 5 days after the patient's admission. Relatives were eligible if they understood French and if no surrogate had been appointed by the patient prior to ICU admission. More than one relative per patient could participate. RESULTS: In total, 87 relatives of 73 patients completed the questionnaire, average age of relatives was 58 ± 15 years, 46% were the spouse, 30% were children/grandchildren. Items classed as being the most important attributes for a reference person were: good knowledge of the patient's wishes and values; an emotional attachment to the patient; being a family member; and having an adequate understanding of the clinical status and clinical history. CONCLUSION: This study identifies the attributes considered by relatives to be most important for designating, among themselves, a reference person for a patient hospitalized in the ICU.

Corporeal Compression at the Onset of Septic shock (COCOONs): a compression method to reduce fluid balance of septic shock patients.

Fluid overload in septic intensive care unit (ICU) patients is common and strongly associated with poor outcome. There is currently no treatment for capillary leak, which is mainly responsible for high positive fluid balance (FB) in sepsis. We hypothesized that increasing interstitial pressure with extensive corporeal compression would reduce FB. The objective of this study was to evaluate the feasibility, efficacy, and safety of a compression treatment during sepsis. This pilot, two-center, single-arm trial enrolled critically ill, non-surgical, septic patients receiving mechanical ventilation. The therapeutic intervention was the early application of compression bandages on more than 80% of the body surface. The primary outcome was negative net FB on day 7. The primary endpoint was reached in 29 of 45 patients (64%) with available data, for a planned objective of 26. By day 4, cumulative FB was 7280 ml [3300-9700]. SOFA- and aged-matched patients from a historical cohort had a significantly higher FB at 1, 2 and 7 days. Tolerance was good, although low-stage pressure ulcers were observed in 16 patients (26%). No effect on intra-abdominal pressure or respiratory plateau pressure was observed. In conclusion, corporeal compression demonstrated potential efficacy in limiting FB during septic shock, with acceptable feasibility and tolerance.
