Evaluation of ventilator associated events in critically ill patients with invasive mechanical ventilation: A prospective cohort study at a resource limited setting in Northern India

PurposeThe primary aim of this study was to identify the modifiable risk factors for acquiring ventilator associated events (VAE). Secondary aims were to investigate the intensive care unit (ICU) course and impact of VAE on patient outcome.MethodsThis prospective, observational single center cohort study included 247 patients on mechanical ventilation for 4 calendar days at a 20-bed ICU between January 2018–June 2019.ResultsVAE occurred in 59 episodes (rate 11.3 per 1000 ventilator-days). The Ventilator Utilization Ratio (VUR) was 0.57. The median time to onset of VAE was 6 days. Sepsis was the most common reason for initiating patients on invasive mechanical ventilation (IMV). Cumulative fluid balance ≥2 l (Odds Ratio 30.92; 95% CI 9.82–97.37) and greater number of days with vasopressor support (Odds Ratio 1.92; 95% CI 1.57–2.36) within 7 days of initiating IMV were significant risk factors for acquiring VAE (p < 0.001). VAE cases were ventilated for significantly more days (20 vs 14 days, p = 0.001, had longer days of ICU stay (29 vs 18 days; p = 0.002) and higher hospital mortality (p = 0.02). Klebsiella pneumoniae was the most common isolate (N = 28) and 32.1% were colistin resistant.ConclusionsProspective intervention studies are needed to determine if targeting these risk factors can lower VAE rates in our setting.     

Do ventilatory parameters influence outcome in patients with severe acute respiratory infection? Secondary analysis of an international,multicentre14-day inception cohort study

PurposeTo investigate the possible association between ventilatory settings on the first day of invasive mechanical ventilation (IMV) and mortality in patients admitted to the intensive care unit (ICU) with severe acute respiratory infection (SARI).Materials and methodsIn this pre-planned sub-study of a prospective, multicentre observational study, 441 patients with SARI who received controlled IMV during the ICU stay were included in the analysis.ResultsICU and hospital mortality rates were 23.1 and 28.1%, respectively. In multivariable analysis, tidal volume and respiratory rate on the first day of IMV were not associated with an increased risk of death; however, higher driving pressure (DP: odds ratio (OR) 1.05; 95% confidence interval (CI): 1.01–1.1, p = 0.011), plateau pressure (Pplat) (OR 1.08; 95% CI: 1.04–1.13, p < 0.001) and positive end-expiratory pressure (PEEP) (OR 1.13; 95% CI: 1.03–1.24, p = 0.006) were independently associated with in-hospital mortality. In subgroup analysis, in hypoxemic patients and in patients with acute respiratory distress syndrome (ARDS), higher DP, Pplat, and PEEP were associated with increased risk of in-hospital death.ConclusionsIn patients with SARI receiving IMV, higher DP, Pplat and PEEP, and not tidal volume, were associated with a higher risk of in-hospital death, especially in those with hypoxemia or ARDS.     

Real-world medication persistence among HIV-1 patients initiating integrase inhibitor-based antiretroviral therapy in Japan

IntroductionMedication persistence has rarely been studied for integrase strand transfer inhibitor (INSTI)-based regimens among patients living HIV (PLWH) in Asia. This study investigated medication persistence for newly prescribed INSTI-based regimens in Japan by comparing single-tablet regimens (STRs) versus multiple-tablet regimens (MTRs), based on the Medical Data Vision database.MethodsAdult PLWH with ≥2 claims for antiretroviral therapy (ART) of interest between 1 January 2017 and 30 June 2018 were included if they had a ≥3-month continuous enrolment prior to the index date and a ≥6-month follow-up after the index date. Medication persistence was measured as the duration from initiation to discontinuation of the prescribed INSTI-based regimen.ResultsOverall, 487 patients were included, with 220 in the STR cohort and 267 in the MTR cohort. Persistence was longer in the STR cohort than in the MTR cohort (mean days on the index regimens: 384.2 vs. 317.3, P < 0.001). MTRs were associated with a higher risk of discontinuation than STRs (hazard ratio [HR], 1.72; 95% confidence interval [CI], 1.18–2.52; P = 0.005). Other factors that were associated with discontinuation were backbone (emtricitabine/tenofovir disoproxil fumarate vs. emtricitabine/tenofovir alafenamide: HR, 5.64; 95% CI, 3.68–8.66; P < 0.001), third agent (raltegravir vs. elvitegravir/cobicistat: HR, 2.06; 95% CI, 1.10–3.86; P = 0.024), age (HR, 1.02; 95% CI, 1.01–1.03; P = 0.007), and the number of non-ART index medications (HR, 1.16; 95% CI, 1.12–1.21; P < 0.001).ConclusionsAmong PLWH newly prescribed an INSTI-based regimen in Japan, STRs were associated with longer persistence than MTRs.     

Abnormal shock index exposure and clinical outcomes among critically ill patients: A retrospective cohort analysis

PurposeTo assess the predictive value of a single abnormal shock index reading (SI ≥0.9; heart rate/systolic blood pressure [SBP]) for mortality, and association between cumulative abnormal SI exposure and mortality/morbidity.Materials and methodsCohort comprised of adult patients with an intensive care unit (ICU) stay ≥24-h (years 2010–2018). SI ≥0.9 exposure was evaluated via cumulative minutes or time-weighted average; SBP ≤100-mmHg was analyzed. Outcomes were in-hospital mortality, acute kidney injury (AKI), and myocardial injury.Results18,197 patients from 82 hospitals were analyzed. Any single SI ≥0.9 within the ICU predicted mortality with 90.8% sensitivity and 36.8% specificity. Every 0.1-unit increase in maximum-SI during the first 24-h increased the odds of mortality by 4.8% [95%CI; 2.6–7.0%; p < .001]. Every 4-h exposure to SI ≥0.9 increased the odds of death by 5.8% [95%CI; 4.6–7.0%; p < .001], AKI by 4.3% [95%CI; 3.7–4.9%; p < .001] and myocardial injury by 2.1% [95%CI; 1.2–3.1%; p < .001]. ≥2-h exposure to SBP ≤100-mmHg was significantly associated with mortality.ConclusionsA single SI reading ≥0.9 is a poor predictor of mortality; cumulative SI exposure is associated with greater risk of mortality/morbidity. The associations with in-hospital mortality were comparable for SI ≥0.9 or SBP ≤100-mmHg exposure. Dynamic interactions between hemodynamic variables need further evaluation among critically ill patients.     

In ICU state anxiety is not associated with posttraumatic stress symptoms over six months after ICU discharge: A prospective study

BackgroundPosttraumatic stress symptoms are common after intensive care treatment. The influence of anxiety during critical illness on the development of posttraumatic stress symptoms needs to be investigated.ObjectiveTo determine the association between anxiety during critical illness (state and trait components) and posttraumatic stress symptoms over six months after ICU discharge.MethodsProspective study including 141 patients admitted ≥24 h to a closed mixed adult ICU in a tertiary hospital. State anxiety was assessed with the Faces Anxiety Scale during ICU stay. Trait anxiety was measured with the State-Trait Anxiety Inventory Form Y-2. Posttraumatic stress symptoms were measured at three and six months after ICU discharge using the Post-Traumatic Stress Symptoms 10-Question Inventory. Clinical and demographical data were also collected. Mixed effect regression models were used to determine if state and trait anxiety were factors significantly associated with posttraumatic stress symptoms over time.ResultsModerate to severe levels of state anxiety in ICU were reported by 81 (57%) participants. Levels of trait anxiety (median 36 IQR: 29–47) were similar to the Australian population. High levels of posttraumatic stress symptoms occurred at three (n = 19, 19%) and six months (n = 15, 17%). Factors independently associated with posttraumatic stress symptoms were trait anxiety (2.2; 95% CI, 0.3–4.1; p = 0.02), symptoms of anxiety after ICU discharge (0.6; 95% CI, 0.2–1.1; p = 0.005), younger age (−1.4; 95% CI, −2.6 to −0.2; p = 0.02) and evidence of mental health treatment prior to the ICU admission (5.2; 95% CI, 1.5–8.9; p = 0.006).ConclusionsPosttraumatic stress symptoms occurred in a significant proportion of ICU survivors and were significantly associated with higher levels of trait anxiety, younger age, mental health treatment prior to the ICU admission and more symptoms of anxiety after ICU discharge. Early assessment and interventions directed to reduce state and trait anxiety in ICU survivors may be of benefit.     

Shifting trends in modes of death in the Intensive Care Unit

PurposeTo describe the way patients die in a Spanish ICU, and how the modes of death have changed in the last 10 years.Materials and methodsRetrospective observational study evaluating all patients who died in a Spanish tertiary ICU over a 10-year period. Modes of death were classified as death despite maximal support (D-MS), brain death (BD), and death following life-sustaining treatment limitation (D-LSTL).ResultsAmongst 9264 ICU admissions, 1553 (16.8%) deaths were recorded. The ICU mortality rate declined (1.7%/year, 95% CI 1.4–2.0; p = 0.021) while ICU admissions increased (3.5%/year, 95% CI 3.3–3.7; p < 0.001). More than half of the patients (888, 57.2%) died D-MS, 389 (25.0%) died after a shared decision of D-LSTL and 276 (17.8%) died due to BD. Modes of death have changed significantly over the past decade. D-LSTL increased by 15.1%/year (95% CI 14.4–15.8; p < 0.001) and D-MS at the end-of-life decreased by 7.1%/year (95% CI 6.6–7.6; p < 0.001 ). The proportion of patients diagnosed with BD remained stable over time.ConclusionsEnd-of-life practices and modes of death in our ICU have steadily changed. The proportion of patients who died in ICU following limitation of life-prolonging therapies substantially increased, whereas death after maximal support occurred significantly less frequently.     

Implementation of lung protective ventilation order to improve adherence to low tidal volume ventilation: A RE-AIM evaluation

PurposeLung protective ventilation (LPV), defined as a tidal volume (Vt) ≤8 cc/kg of predicted body weight, reduces ventilator-induced lung injury but is applied inconsistently.Materials and methodsWe conducted a prospective, quasi-experimental, cohort study of adults mechanically ventilated admitted to intensive care units (ICU) in the year before, year after, and second year after implementation of an electronic medical record based LPV order, and a cross-sectional qualitative study of ICU providers regarding their perceptions of the order. We applied the Reach, Efficacy, Adoption, Implementation, and Maintenance (RE-AIM) framework to evaluate the implementation.ResultsThere were 1405, 1424, and 1342 in the control, adoption, and maintenance cohorts, representing 95% of mechanically ventilated adult ICU patients. The overall prevalence of LPV increased from 65% to 73% (p < 0.001, adjusted-OR for LPV adherence: 1.9, 95% CI 1.5–2.3), but LPV adherence in women was approximately 30% worse than in men (women: 44% to 56% [p < 0.001],men: 79% to 86% [p < 0.001]). ICU providers noted difficulty obtaining an accurate height measurement and mistrust of the Vt calculation as barriers to implementation. LPV adherence increased further in the second year post implementation.ConclusionWe designed and implemented an LPV order that sustainably improved LPV adherence across diverse ICUs.     

Critically Ill Health Care-Associated Urinary Tract Infection: Broad vs. Narrow Antibiotics in the Emergency Department Have Similar Outcomes

BackgroundUrinary tract infection (UTI) is the second most common infection requiring intensive care unit (ICU) admission in emergency department (ED) patients. Optimal empiric management for health care-associated (HCA) UTI is unclear, particularly in the critically ill.ObjectiveTo compare clinical failure of broad vs. narrow antibiotic selection in the ED for patients presenting with HCA UTI admitted to the ICU.MethodsObservational cohort of patients started on empiric antibiotic for UTI with at least one HCA risk factor (recurrent UTI, chronic urinary catheter or dialysis, urologic procedures, previous antibiotic exposure, hospitalization, or group facility residence). Broad antibiotics covered Pseudomonas spp. and extended-spectrum beta-lactamase. Clinical failure was a composite of multiorgan dysfunction (MODS) by day 2 and in-hospital mortality. Secondary outcomes were length of stay (LOS), readmission, recurrent infection, development of multidrug-resistant organisms, and Clostridium difficile infection. Associations were reported with odds ratios (OR) and 95% confidence intervals (CI).ResultsThere were 272 patients included; 196 (72.1%) received broad and 76 (27.9%) received narrow therapy. There was no association between antibiotic selection and clinical failure (OR 1.05, 95% CI 0.5–2.25, p = 0.89) or between antibiotic selection and number of HCA risk factors (OR 0.98, 95% CI 0.73–1.31, p = 0.87). There was an association between clinical failure and MODS on ICU admission (OR 9.14, 95% CI 4.70–17.78, p < 0.001). Hospital LOS and readmission did not differ between antibiotic groups.ConclusionInitial empiric broad or narrow antibiotic coverage in HCA UTI patients who presented to the ED and required ICU admission had similar clinical outcomes.     

Tuberculous ARDS is associated with worse outcome when compared with non-tuberculous infectious ARDS

BackgroundPatients with tuberculosis (TB) developing acute respiratory distress syndrome (ARDS) may have a higher mortality when compared with ARDS of other infectious etiology.MethodologyIn this single-centre retrospective cohort study spanning 5-years (2012 to 2016), TB-ARDS patients were age and gender matched (1:2) with non-TB infectious ARDS and followed up until death or hospital discharge. Clinical profile, treatment and outcomes were compared using t-test and Chi-square as appropriate. Mortality predictors were explored using Conditional Poisson regression analysis and expressed as relative risk (RR) with 95% confidence interval (CI).ResultsOf the 516 ARDS patients, 74 TB-ARDS and 148 non-TB infectious ARDS patients were included. Although admission APACHE-II (21.4 ± 7.1 vs. 17.6 ± 6.8, p < 0.001), incidence of shock (36.5% vs. 19.1%, p = 0.005) and mortality (59.5% vs. 29.7%, p < 0.001) were significantly higher in TB-ARDS than non-TB etiology, overall ICU length of stay and nosocomial infections were similar in both groups. On regression analysis, after adjusting for confounders, TB-ARDS (RR 1.82; 95% CI 1.13–2.92) and need for inotropes (RR 3.49; 95% CI 1.44–8.46) were independently associated with death.ConclusionPatients with TB-ARDS presented sicker and had higher mortality when compared with ARDS due to non-TB infectious etiology.     

The needs of patients with post–intensive care syndrome: A prospective,observational study

BackgroundThe needs of critical illness survivors and how best to address these are unclear.ObjectivesThe objective of this study was to identify critical illness survivors who had developed post–intensive care syndrome and to explore their use of community healthcare resources, the socioeconomic impact of their illness, and their self-reported unmet healthcare needs.MethodsPatients from two intensive care units (ICUs) in Western Australia who were mechanically ventilated for 5 days or more and/or had a prolonged ICU admission were included in this prospective, observational study. Questionnaires were used to assess participants' baseline health and function before admission, which were then repeated at 1 and 3 months after ICU discharge.ResultsFifty participants were enrolled. Mean Functional Activities Questionnaire scores increased from 1.8 out of 30 at baseline (95% confidence interval [CI]: 0–3.5) to 8.9 at 1 month after ICU discharge (95% CI: 6.5–11.4; P = <0.001) and 7.0 at 3 months after ICU discharge (95% CI: 4.9–9.1; P = < 0.001). Scores indicating functional dependence increased from 8% at baseline to 54% and 33% at 1 and 3 months after ICU discharge, respectively. Statistically significant declines in health-related quality of life were identified in the domains of Mobility, Personal Care, Usual Activities, and Pain/Discomfort at 1 month after ICU discharge and in Mobility, Personal Care, Usual Activities, and Anxiety/Depression at 3 months after ICU discharge. An increase in healthcare service use was identified after ICU discharge. Participants primarily identified mental health services as the service that they felt they would benefit from but were not accessing. Very low rates of return to work were observed, with 35% of respondents at 3 months, indicating they were experiencing financial difficulty as a result of their critical illness.ConclusionsStudy participants developed impairments consistent with post–intensive care syndrome, with associated negative socioeconomic ramifications, and identified mental health as an area they need more support in.     

Associations between hospital occupancy,intensive care unit transfer delay and hospital mortality

PurposeHospital occupancy (HospOcc) pressures often lead to longer intensive care unit (ICU) stay after physician recognition of discharge readiness. We evaluated the relationships between HospOcc, extended ICU stay, and patient outcomes.Materials and methods7-year retrospective cohort study of 8500 alive discharge encounters from 4 adult ICUs of a tertiary hospital. We estimated associations between i) HospOcc and ICU transfer delay; and ii) ICU transfer delay and hospital mortality.ResultsMedian (IQR) ICU transfer delay was 4.8 h (1.6–11.7), 1.4% (119) suffered in-hospital death, and 4% (341) were readmitted. HospOcc was non-linearly related with ICU transfer delay, with a spline knot at 80% (mean transfer delay 8.8 h [95% CI: 8.24, 9.38]). Higher HospOcc level above 80% was associated with longer transfer delays, (mean increase 5.4% per % HospOcc increase; 95% CI, 4.7 to 6.1; P < .001). Longer ICU transfer delay was associated with increasing odds of in-hospital death or ICU readmission (odds ratio 1.01 per hour; 95% CI 1.00 to 1.01; P = .04) but not with ICU readmission alone (OR 1.01 per hour; 95% CI 1.00 to 1.01, P = .14).ConclusionsICU transfer delay exponentially increased above a threshold hospital occupancy and may be associated with increased hospital mortality.     

Association between habitual hot spring bathing and depression in Japanese older adults: A retrospective study in Beppu

ObjectivesThermal therapy is used to manage various psychological diseases, such as depression. We investigated the relationship between hot spring bathing and depression in older adults using questionnaire responses.Design and SettingWe comprehensively evaluated the preventive effects of long-term hot spring bathing in 10429 adults aged ≥ 65 years in Beppu, Japan, by conducting a questionnaire study on the prevalence of depression (n = 219).Main outcome measuresOdds ratios (ORs) with 95% confidence intervals (CIs) were calculated using a multivariable logistic regression model for history of depression.ResultsA separate multivariable logistic regression model for inference showed that female sex (OR, 1.56; 95 % CI, 1.17–2.08; p = 0.002), arrhythmia (OR, 1.73; 95 % CI, 1.18–2.52; p = 0.004), hyperlipidemia (OR, 1.63; 95 % CI, 1.14–2.32; p = 0.006), renal disease (OR, 2.26; 95 % CI, 1.36–3.75; p = 0.001), collagen disease (OR, 2.72; 95 % CI, 1.48–5.02; p = 0.001), allergy (OR, 1.97; 95 % CI, 1.27–3.04; p = 0.002), and habitual daily hot spring bathing (OR, 0.63; 95 % CI, 0.41–0.94; p = 0.027) were independently significantly associated with a history of depression.ConclusionsWe found an inverse relationship between habitual daily hot spring bathing and history of depression. Prospective randomized controlled trials on habitual daily hot spring bathing as a treatment for depression are warranted to investigate whether the use of hot springs can provide relief to those with psychiatric and mental health disorders.     

The role of the quick sequential organ failure assessment score (qSOFA) and modified early warning score (MEWS) in the pre-hospitalization prediction of sepsis prognosis

ObjectiveMany biomarkers and scoring systems to make clinical predictions about the prognosis of sepsis have been investigated. In this study, we aimed to assess the use of the quick sequential organ failure assessment score (qSOFA) and modified early warning score (MEWS) scoring systems in emergency health care services for sepsis to predict intensive care hospitalization and 28-day mortality.MethodPatients who arrived by ambulance at the Emergency Department (ED) of Dışkapı YıldırımBeyazıt Training and Research Hospital between January 2017 and December 2019, and who were diagnosed with sepsis and admitted to the hospital were included in the study. Demographic data and physiological parameters from 112 ambulance case delivery forms were recorded.QSOFA and MEWS scores were calculated from vital parameters.ResultsOf the 266 patients diagnosed with sepsis, 50% (n = 133) were female, and the mean age was 74.8 ± 13. The difference between the rate of intensive care (ICU) hospitalization and mortality for patients with a high MEWS and qSOFA score and patients whose MEWS and qSOFA score were lower was found to be statistically significant (p < 0.05). Thus, the criteria for MEWS and qSOFA could determine ICU hospitalization and early mortality. Those with a high MEWS value had a mortality rate approximately 1.24 times higher than those with a low MEWS value (p < 0.001, 95% CI: 1.110–1.385), while those with a high qSOFA score had a mortality rate approximately 2.0 times higher than those with a low qSOFA score (p < 0.001, 95% CI: 1.446–2.693). Those with a high MEWS were 1.34 times more likely than hose with a lower MEWS to require ICU hospitalization (p < 0.001, 95% CI: 1.1773–1.5131), while patients with a high qSOFA score were 3.21 times more likely than those with a lower qSOFA score to require ICU care (p < 0.001, 95% CI: 2.2289–4.6093).ConclusionAlthough qSOFA and MEWS are clinical scores used to identify septic patients outside the critical care unit, we believe that patients already diagnosed with sepsis can be assessed with qSOFA and MEWS prior to hospitalization to predict intensive care hospitalization and mortality. qSOFA was found be more valuable than MEWS in determining the prognosis of pre-hospitalization sepsis.     

Intervention effect of neuromuscular electrical stimulation on ICU acquired weakness: A meta-analysis

ObjectiveThe early use of neuromuscular electrical stimulation (NMES) to prevent intensive care unit-acquired weakness (ICU-AW) in critical patients is still a controversial topic. We conducted a systematic review to clarify the effectiveness of NMES in preventing ICU-AW.MethodsThe Cochrane Library, PubMed, EMBASE, MEDLINE, Web of Science, Ovid, CNKI, Wanfang, VIP, China Biology Medicine disc (CBMdisc) and other databases were searched for randomized controlled trials on the influence of NMES on ICU-AW. The studies were selected according to the inclusion and exclusion criteria. After data and quality were evaluated, a meta-analysis was performed by RevMan 5.3 software.ResultsA total of 11 randomized controlled trials with 576 patients were included. The meta-analysis results showed that NMES can improve muscle strength [MD = 1.78, 95% CI (0.44, 3.12, P = 0.009); shorten the mechanical ventilation (MV) time [SMD = −0.65, 95% CI (−1.03, −0.27, P = 0.001], ICU length of stay [MD = −3.41, 95% CI (−4.58, −4.24), P < 0.001], and total length of stay [MD = −3.97, 95% CI (−6.89, −1.06, P = 0.008]; improve the ability of patients to perform activities of daily living [SMD = 0.9, 95% CI (0.45, 1.35), P = 0.001]; and increase walking distance [MD = 239.03, 95% CI (179.22298.85), P < 0.001]. However, there is no evidence indicating that NMES can improve the functional status of ICU patients during hospitalization, promote the early awakening of patients or reduce mortality (P > 0.05).ConclusionEarly implementation of the NMES intervention in ICU patients can prevent ICU-AW and improve their quality of life by enhancing their muscle strength and shortening the MV duration, length of stay in the ICU and total length of stay in the hospital.     

Factors associated with a persistent delirium in the intensive care unit: A retrospective cohort study

PurposeTo explore differences between ICU patients with persistent delirium (PD), non-persistent delirium (NPD) and no delirium (ND), and to determine factors associated with PD.Materials and methodsRetrospective cohort study including all ICU adults admitted for ≥12 h (January 2015–February 2020), assessable for delirium and followed during their entire hospitalization. PD was defined as ≥14 days of delirium. Factors associated with PD were determined using multivariable logistic regression analysis.ResultsOut of 10,295 patients, 3138 (30.5%) had delirium, and 284 (2.8%) had PD. As compared to NPD (n = 2854, 27.7%) and ND (n = 7157, 69.5%), PD patients were older, sicker, more physically restrained, longer comatose and mechanically ventilated, had a longer ICU and hospital stay, more ICU readmissions and a higher mortality rate.Factors associated with PD were age (adjusted odds ratio [aOR] 1.03; 95% confidence interval [CI] 1.02–1.04); emergency surgical (aOR 1.84; 95%CI 1.26–2.68) and medical (aOR 1.57; 95%CI 1.12–2.21) referral, mean Sequential Organ Failure Assessment (SOFA) score before delirium onset (aOR 1.18; 95%CI 1.13–1.24) and use of physical restraints (aOR 5.02; 95%CI 3.09–8.15).ConclusionsPatients with persistent delirium differ in several characteristics and had worse short-term outcomes. Physical restraints were the most strongly associated with PD.     

Gender distribution of editorial board members in critical care journals: Assessment of gender parity

PurposeTo reveal factors related to gender parity on editorial boards of critical care journals indexing in SCI-E.MethodsThe genders were defined according to data obtained from journals' websites between 01—30 September 2022. Publisher properties and journal metrics were analyzed by using Chi-square, Fisher exact, Mann–Whitney U tests, and Spearman's correlation coefficient. Logistic regression analysis was used to reveal independent factors.ResultsWomen's representation on editorial boards was 23.6%. The USA (OR, 0.04, 95% CI, 0.01–0.15, p < 0.001) and Netherlands (OR, 0.04, 95% CI, 0.01–0.16, p < 0.001) as publisher's countries, an IF >5 (OR, 0.25, 95% CI, 0.17–0.38, p < 0.001), publication duration <30 years (OR, 0.09, 95% CI, 0.06–0.12, p < 0.001), multidisciplinary perspective of editorial policy (OR, 0.46, 95% CI, 0.32–0.65, p < 0.001), journals categorized also in nursing (OR, 0.38, 95% CI, 0.22–0.66, p < 0.001), and being a section editor (OR, 0.49, 95% CI, 0.32–0.74, p = 0.001) were associated with gender parity. Europe as a journal continent (OR, 36.71, 95% CI, 8.39–160.53, p < 0.001) was related to gender disparity.ConclusionsFurther efforts are needed to expand diversity policies in critical care medicine.     

Prevalence and impact of frailty on mortality in elderly ICU patients: a prospective,multicenter, observational study

Purpose

Frailty is a recent concept used for evaluating elderly individuals. Our study determined the prevalence of frailty in intensive care unit (ICU) patients and its impact on the rate of mortality.

Methods

A multicenter, prospective, observational study performed in four ICUs in France included 196 patients aged ≥65 years hospitalized for >24 h during a 6-month study period. Frailty was determined using the frailty phenotype (FP) and the clinical frailty score (CFS). The patients were separated as follows: FP score <3 or ≥3 and CFS <5 or ≥5.

Results

Frailty was observed in 41 and 23 % of patients on the basis of an FP score ≥3 and a CFS ≥5, respectively. At admission to the ICU, the Simplified Acute Physiology Score II (SAPS II) and Sequential Organ Failure Assessment (SOFA) scores did not differ between the frail and nonfrail patients. In the multivariate analysis, the risk factors for ICU mortality were FP score ≥3 [hazard ratio (HR), 3.3; 95 % confidence interval (CI), 1.6–6.6; p < 0.001], male gender (HR, 2.4; 95 % CI, 1.1–5.3; p = 0.026), cardiac arrest before admission (HR, 2.8; 95 % CI, 1.1–7.4; p = 0.036), SAPS II score ≥46 (HR, 2.6; 95 % CI, 1.2–5.3; p = 0.011), and brain injury before admission (HR, 3.5; 95 % CI, 1.6–7.7; p = 0.002). The risk factors for 6-month mortality were a CFS ≥5 (HR, 2.4; 95 % CI, 1.49–3.87; p < 0.001) and a SOFA score ≥7 (HR, 2.2; 95 % CI, 1.35–3.64; p = 0.002). An increased CFS was associated with significant incremental hospital and 6-month mortalities.

Conclusions

Frailty is a frequent occurrence and is independently associated with increased ICU and 6-month mortalities. Notably, the CFS predicts outcomes more effectively than the commonly used ICU illness scores.     

Lower mean phosphate independently predicts mortality in critically ill patients: Results from a prospective cohort study

PurposeTo evaluate lower mean phosphate as a prognostic tool in critically ill patients.MethodsThis is a prospective single-center cohort study including adult patients (> 18 years) with a length of intensive care unit (ICU) stay of at least 24 h. Phosphatemia was evaluated within 1 h of ICU admission and once daily. Mean phosphate, calculated by the simple arithmetic mean of daily phosphate measurements, was proposed and tested. Standard severity scores were applied. Multivariate and survival analyses were performed.ResultsA total of 317 patients were included, of whom 111 (35%) presented hypophosphatemia. Hypophosphatemia associated with surgical conditions, nutritional therapy, hypovitaminosis D, hyperparathyroidism, mechanical ventilation (need and duration), and ICU and hospital length of stay were evaluated. Admission APACHE II and SOFA (ICU days 1, 3, and 7) scores and ICU and in-hospital mortality were greater in the hypophosphatemia group than control group. Higher APACHE II (RR: 1.1; 95%CI: 1.01–1.2; p = 0.045) and lower mean phosphate (RR: 0.02; 95%CI: 0.001–0.09; p = 0.044) independently predicted ICU and in-hospital mortality.ConclusionsHypophosphatemia is frequent in the ICU, and was associated with unfavorable outcomes. This study introduces the importance of longitudinal monitoring of phosphate levels, since lower mean phosphate is an independent predictor of mortality in critically ill patients.     

Use of High-Flow Nasal Cannula for Immunocompromise and Acute Respiratory Failure: A Systematic Review and Meta-Analysis

BackgroundAcute respiratory failure (ARF) is a common cause of emergency department (ED) and intensive care unit (ICU) admissions. High-flow nasal cannula oxygen therapy (HFNC) is widely used for patients with ARF.ObjectiveOur aim was to evaluate the latest evidence regarding the application of HFNC in immunocompromised patients with ARF.MethodsWe searched PubMed, Embase, and Cochrane databases from inception to January 2019. The primary outcome was short-term mortality and the secondary outcomes were intubation rate and length of ICU stay.ResultsEight studies involving 2,179 immunocompromised subjects with ARF were included. No significant differences for short-term mortality were observed when comparing HFNC with conventional oxygen therapy (COT) (risk ratio [RR] 0.89; 95% confidence interval [CI] 0.73 to 1.09; p = 0.25, I² = 47%) and with noninvasive ventilation (NIV) (RR 0.66; 95% CI 0.37 to 1.18; p = 0.16, I² = 58%). Lower intubation rates were found when comparing HFNC with COT (RR 0.89; 95% CI 0.80 to 0.99; p = 0.03, I² = 0%) and no significant difference was found between HFNC and NIV (RR 0.74; 95% CI 0.46 to 1.19; p = 0.22, I² = 67%). The length of ICU stay was similar when comparing HFNC with COT (mean difference [MD] 0.59; 95% CI –1.68 to 2.85; p = 0.61, I² = 56%), but was significantly shorter when HFNC was compared with NIV (MD –2.13; 95% CI –3.98 to –0.29; p = 0.02, I² = 0%).ConclusionsThere was no significant difference in short-term mortality with use of HFNC when compared with COT or NIV for immunocompromised patients with ARF. A lower intubation rate than COT and a shorter length of ICU stay than NIV were observed in the HFNC group.     

Annual prevalence,characteristics, and outcomes of intensive care patients with skin or soft tissue infections in Australia and New Zealand: A retrospective cohort study between 2006-2017

BackgroundThere are limited published data on the epidemiology of skin and soft tissue infections (SSTIs) requiring intensive care unit (ICU) admission. This study intended to describe the annual prevalence, characteristics, and outcomes of critically ill adult patients admitted to the ICU for an SSTI.MethodsThis was a registry-based retrospective cohort study, using data submitted to the Australian and New Zealand Intensive Care Society Adult Patient Database for all admissions with SSTI between 2006 and 2017. The inclusion criteria were as follows: primary diagnosis of SSTI and age ≥16 years. The exclusion criteria were as follows: ICU readmissions (during the same hospital admission) and transfers from ICUs from other hospitals. The primary outcome was in-hospital mortality, and the secondary outcomes were ICU mortality and length of stay (LOS) in the ICU and hospital with independent predictors of outcomes.ResultsAdmissions due to SSTI accounted for 10 962 (0.7%) of 1 470 197 ICU admissions between 2006 and 2017. Comorbidities were present in 25.2% of the study sample. The in-hospital mortality was 9% (991/10 962), and SSTI necessitating ICU admission accounted for 0.07% of in-hospital mortality of all ICU admissions between 2006 and 2017. Annual prevalence of ICU admissions for SSTI increased from 0.4% to 0.9% during the study period, but in-hospital mortality decreased from 16.1% to 6.8%. The median ICU LOS was 2.1 days (interquartile range = 3.4), and the median hospital LOS was 12.1 days (interquartile range = 20.6). ICU LOS remained stable between 2006 and 2017 (2.0–2.1 days), whereas hospital LOS decreased from 15.7 to 11.2 days. Predictors for in-hospital mortality included Australian and New Zealand Risk of Death scores [odds ratio (OR): 1.07; confidence interval (CI) (1.05, 1.09); p < 0.001], any comorbidity except diabetes [OR: 2.00; CI (1.05, 3.79); p = 0.035], and admission through an emergency response call [OR: 2.07; CI (1.03, 4.16); p = 0.041].ConclusionsSSTIs are uncommon as primary ICU admission diagnosis. Although the annual prevalence of ICU admissions for SSTI has increased, in-hospital mortality and hospital LOS have decreased over the last decade.
