Abstract Background The post intensive care syndrome (PICS) gathers various disabilities, associated with a substantial healthcare use. However, patients’ comorbidities and active medical conditions prior to intensive care unit (ICU) admission may partly drive healthcare use after ICU discharge. To better understand retative contribution of critical illness and PICS—compared to pre-existing comorbidities—as potential determinant of post-critical illness healthcare use, we conducted a population-based evaluation of patients’ healthcare use trajectories. Results Using discharge databases in a 2.5-million-people region in France, we retrieved, over 3 years, all adult patients admitted in ICU for septic shock or acute respiratory distress syndrome (ARDS), intubated at least 5 days and discharged alive from hospital: 882 patients were included. Median duration of mechanical ventilation was 11 days (interquartile ranges [IQR] 8;20), mean SAPS2 was 49, and median hospital length of stay was 42 days (IQR 29;64). Healthcare use (days spent in healthcare facilities) was analyzed 2 years before and 2 years after ICU admission. Prior to ICU admission, we observed, at the scale of the whole study population, a progressive increase in healthcare use. Healthcare trajectories were then explored at individual level, and patients were assembled according to their individual pre-ICU healthcare use trajectory by clusterization with the K-Means method. Interestingly, this revealed diverse trajectories, identifying patients with elevated and increasing healthcare use (n = 126), and two main groups with low (n = 476) or no (n = 251) pre-ICU healthcare use. In ICU, however, SAPS2, duration of mechanical ventilation and length of stay were not different across the groups. Analysis of post-ICU healthcare trajectories for each group revealed that patients with low or no pre-ICU healthcare (which represented 83% of the population) switched to a persistent and elevated healthcare use during the 2 years post-ICU. Conclusion For 83% of ARDS/septic shock survivors, critical illness appears to have a pivotal role in healthcare trajectories, with a switch from a low and stable healthcare use prior to ICU to a sustained higher healthcare recourse 2 years after ICU discharge. This underpins the hypothesis of long-term critical illness and PICS-related quantifiable consequences in healthcare use, measurable at a population level.

Sepsis And Septic Shock

Introduction: Sepsis is a systemic infection that can rapidly progress into multi organ failure and shock if left untreated. Previous studies have demonstrated the utility of point of care ultrasound (POCUS) in the evaluation of patients with sepsis. However, limited data exists on the evaluation of the tricuspid annular plane of systolic excursion (TAPSE) in patients with sepsis. Methods: We prospectively enrolled patients who presented to the emergency department (ED) with concern for severe sepsis or septic shock in a pilot study. In patients that screened positive, the treating physician then performed POCUS to measure the TAPSE value. We compared the intensive care unit (ICU) admission rate, hospital length of stay, and morbidity with their respective TAPSE values. Results: We enrolled 24 patients in the study. Eight patients had TAPSE values less than 16 millimeters (mm), two patients had TAPSE values between 16mm-20mm, and fourteen patients had TAPSE values greater than 20mm. There was no statistically significant association between TAPSE levels and ICU admission (p=0.16), or death (p=0.14). The difference of length of stay (LOS) was not statistically significant in case of hospital LOS (p= 0.72) or ICU LOS. Conclusion: Our pilot data did not demonstrate a correlation between severe sepsis or septic shock and TAPSE values. This may be due to several factors including patient comorbidities, strict definitions of sepsis and septic shock, as well as the absence of septic cardiomyopathy (SCM) in patients with sepsis and septic shock. Future large-scale studies are needed to determine if TAPSE can be beneficial in the ED evaluation of patients with concern for SCM.

Life Threatening Complication

Abstract When patients with hematological malignancies develop a life-threatening complication there may be reluctance to admit them in intensive care units (ICU) because of their supposed poor prognosis. The objective of this study was to evaluate the mortality during the ICU admission, the long-term survival, and the prognostic factors that contribute to the survival of patients with hematological malignancies who were transferred to ICU due to a life-threatening complication. From January 2000 to May 2004, the variables at admission and during stay at the ICU, and the follow-up were reviwed in 58 consecutive critically-ill patients with a hematological malignancy from a single institution. The median age (range) was 55 (15–75) years and the male/female ratio was: 38/20. The hematological underlying diseases were: NHL (18 patients), AML (10), ALL (9), MM (6), chronic lymphoproliferative disorder (5), chronic myeloproliferative disorder (4), myelodysplastic syndrome (3), aplastic anemia (2) and Hodgkin’s lymphoma (1). Seven patients had received a hematopoietic stem cell transplant prior to the ICU admission. The main life-threatening acute illness precipitating the ICU transfer were: septic shock (26 patients, 45%), respiratory failure (21, 36%), non-septic hemodynamic instability (5, 9%), respiratory arrest related to a neurological event (2, 3%), post-surgical status (2, 3%), cardiac infarction (1, 2%) and polytrauma (1, 2%). Twenty-one patients (36%) could be discharged alive from the ICU. The median overall survival (range) for ICU discharged patients was 23 (0–54) months, with a median follow-up of 8 months. The actuarial probability of discharged patients to be alive was 56% (CI 95%: 31–75) at 6 months, and a 48% (CI 95%: 13–70) at 12 months. The mean Acute Physiology and Chronic Health Evaluation II (APACHE) score at admission, neutropenia, need for mechanical ventilation, maximum FIO2 requirements at 24 hours from admission, presence of septic shock, renal impairment or liver damage, were associated with a poor outcome in the univariate analysis. A documented infection was not associated with a higher mortality rate except for fungal infection. The APACHE II score at 48 and 72 hours of ICU admission decreased both in surviving and non-surviving patients due to therapeutic manoeuvres and was not predictive of the outcome. The type of the hematological malignancy, its prognosis and the presence of active disease at ICU admission did not predict patients outcome in our series. The number of failing organs also predicted a poorer survival for patients with more than two failing organs (p=0.038). In a multivariate logistical regression model, only the cardiovascular failure requiring vasoactive and the need of mechanical ventilation predicted outcome in the ICU admitted patients diagnosed with a hematological malignancy. A high proportion of admitted patients with a life-threatening complication and a hematological malignancy could be discharged from ICU. Although the mortality rate immediately after ICU discharge was high, those patients that survived the first week outside ICU had an expected survival only conditioned by their hematological malignancy.

Prescription Opioid Use

Objective Several studies show that chronic opioid dependence leads to higher in-hospital mortality, increased risk of hospital readmissions, and worse outcomes in trauma cases. However, the association of outpatient prescription opioid use on morbidity and mortality has not been adequately evaluated in a critical care setting. The purpose of this study was to determine if there is an association between chronic opioid use and mortality after an ICU admission. Design A single-center, longitudinal retrospective cohort study of all Intensive Care Unit (ICU) patients admitted to a tertiary-care academic medical center from 2001 to 2012 using the MIMIC-III database. Setting Medical Information Mart for Intensive Care III database based in the United States. Patients Adult patients 18 years and older were included. Exclusion criteria comprised of patients who expired during their hospital stay or presented with overdose; patients with cancer, anoxic brain injury, non-prescription opioid use; or if an accurate medication reconciliation was unable to be obtained. Patients prescribed chronic opioids were compared with those who had not been prescribed opioids in the outpatient setting. Interventions None. Measurements and main results The final sample included a total of 22,385 patients, with 2,621 (11.7%) in the opioid group and 19,764 (88.3%) in the control group. After proceeding with bivariate analyses, statistically significant and clinically relevant differences were identified between opioid and non-opioid users in sex, length of hospital stay, and comorbidities. Opioid use was associated with increased mortality in both the 30-day and 1-year windows with a respective odds ratios of 1.81 (95% CI, 1.63–2.01; p<0.001) and 1.88 (95% CI, 1.77–1.99; p<0.001), respectively. Conclusions Chronic opioid usage was associated with increased hospital length of stay and increased mortality at both 30 days and 1 year after ICU admission. Knowledge of this will help providers make better choices in patient care and have a more informed risk-benefits discussion when prescribing opioids for chronic usage.

The Impact

Excessive alcohol use is associated with increased health care utilisation and increased mortality. This observational study sought to identify the proportion of patients admitted with a critical illness in which alcohol misuse contributed, and to examine the resource use for this group. We performed an observational retrospective database review of all admissions to the Alice Springs Hospital intensive care unit (ICU) between 1 January 2009 and 31 December 2015. The Alice Springs Hospital ICU is a ten-bed unit located in Central Australia, with approximately 600 admissions annually. The per capita consumption of alcohol in Central Australia is approximately 1.5 times the national average. The primary aim was to determine the proportion of admissions to intensive care in which alcohol misuse was identified as a contributing cause. Secondary aims examined resource utilisation including ICU and hospital length of stay, need for and duration of mechanical ventilation, and ICU re-admission. There were 3,768 admissions involving 2,670 individual patients. Of these admissions 947 (25%) were associated with alcohol misuse. Admissions associated with alcohol were significantly more likely to require mechanical ventilation (30% versus 20%, P <0.01), and had a significantly longer ICU length of stay (2.1 versus 1.9 days, P <0.05). The proportion of admissions in which alcohol misuse was implicated is amongst the highest in the published literature. The results of this study should drive further policy change directed at harm minimisation, and warrant more detailed epidemiological work at both a local and national level.

Abstract Background Recommendations are for nearly universal venous thromboembolism (VTE) prophylaxis in critically ill hospitalized patients because of their well-recognized risks. In those intensive care units (ICUs) where patient care is more uniformly directed, it may be expected that VTE prophylaxis would more closely follow this standard over units that are less uniform, such as open-model ICUs. Methods This was a retrospective cohort study on all patients aged 18+ admitted to an open ICU between 6/1/2017 and 5/31/2018. Patients were excluded if they had instructions to receive comfort measures only or required therapeutic anticoagulant administration. Prophylaxis administration practices, including administration of mechanical and/or pharmacologic prophylaxis and delayed (≥48 h post-ICU admission) initiation of pharmacologic prophylaxis, were compared between patients admitted to the ICU by the trauma service versus other departments. Root causes for opting out of pharmacological prophylaxis were documented and compared between the two study groups. Results One-hundred two study participants were admitted by the trauma service, and 98 were from a non-trauma service. Mechanical (98% trauma vs. 99% non-trauma, P = 0.99) and pharmacologic (54% vs. 44%, P = 0.16) prophylaxis rates were similar between the two admission groups. The median time from ICU admission to pharmacologic prophylaxis initiation was 53 h for the trauma service and 10 h for the non–trauma services (P ≤ 0.01). In regression analyses, trauma-service admission (odds ratio (OR) = 2.88, 95% confidence interval (CI) 1.21–6.83) and increasing ICU length of stay (OR = 1.13, 95% CI 1.05–1.21) were independently associated with pharmacologic prophylaxis use. Trauma-service admission (OR = 8.30, 95% CI 2.18–31.56) and increasing hospital length of stay (OR = 1.15, 95% CI 1.03–1.28) were independently associated with delayed prophylaxis initiation. Conclusions Overall, the receipt of VTE prophylaxis of any type was close to 100%, due to the nearly universal use of mechanical compression devices among ICU patients in this study. However, when examining pharmacologic prophylaxis specifically, the rate was considerably lower than is currently recommended: 54% among the trauma services and 44% among non-trauma services.

Objectives: To compare the characteristics and outcomes of patients presenting to hospital with alcohol-induced and gallstone-induced acute pancreatitis. Methods: Retrospective study of all patients with alcohol-induced or gallstone-induced pancreatitis during the period 1 June 2012 to 31 May 2016. The primary outcome measure was hospital mortality. Secondary outcome measures included hospital length of stay, requirements for intensive care unit admission, intensive care unit mortality, mechanical ventilation, renal replacement therapy, requirement of inotropes and total parenteral nutrition. Results: A total of 642 consecutive patients (49% alcohol; 51% gallstone) were included. No statistically significant differences were found between alcohol-induced and gallstone-induced acute pancreatitis with respect to hospital mortality, requirement for intensive care unit admission, intensive care unit mortality and requirement for mechanical ventilation, renal replacement therapy, inotropes or total parenteral nutrition. There was significant difference in hospital length of stay (3.07 versus 4.84; p  < 0.0001). On multivariable regression analysis, Bedside Index of Severity in Acute Pancreatitis score (estimate: 0.393; standard error: 0.058; p < 0.0001) and admission haematocrit (estimate: 0.025; standard error: 0.008; p = 0.002) were found to be independently associated with prolonged hospital length of stay. Conclusion: Hospital mortality did not differ between patients with alcohol-induced and gallstone-induced acute pancreatitis. The duration of hospital stay was longer with gallstone-induced pancreatitis. Bedside Index of Severity in Acute Pancreatitis score and admission haematocrit were independently associated with hospital length of stay.

Abstract Background Mortality and other clinical outcomes between culture-negative and culture-positive septic patients have been documented inconsistently and are very controversial. A systematic review and meta-analysis was performed to compare the clinical outcomes of culture-negative and culture-positive sepsis or septic shock. Methods We searched the PubMed, Cochrane and Embase databases for studies from inception to the 1st of January 2021. We included studies involving patients with sepsis or septic shock. All authors reported our primary outcome of all-cause mortality and clearly compared culture-negative versus culture-positive patients with clinically relevant secondary outcomes (ICU length of stay, hospital length of stay, mechanical ventilation requirements, mechanical ventilation duration and renal replacement requirements). Results were expressed as odds ratio (OR) and mean difference (MD) with accompanying 95% confidence interval (CI). Results Seven studies including 22,655 patients were included. The primary outcome of this meta-analysis showed that there was no statistically significant difference in the all-cause mortality between two groups (OR = 0.95; 95% CI, 0.88 to 1.01; P = 0.12; Chi-2 = 30.71; I2 = 80%). Secondary outcomes demonstrated that there was no statistically significant difference in the ICU length of stay (MD = − 0.19;95% CI, − 0.42 to 0.04; P = 0.10;Chi-2 = 5.73; I2 = 48%), mechanical ventilation requirements (OR = 1.02; 95% CI, 0.94 to 1.11; P = 0.61; Chi2 = 6.32; I2 = 53%) and renal replacement requirements (OR = 0.82; 95% CI, 0.67 to 1.01; P = 0.06; Chi-2 = 1.21; I2 = 0%) between two groups. The hospital length of stay of culture-positive group was longer than that of the culture-negative group (MD = − 3.48;95% CI, − 4.34 to − 2.63; P < 0.00001;Chi-2 = 1.03; I2 = 0%). The mechanical ventilation duration of culture-positive group was longer than that of the culture-negative group (MD = − 0.64;95% CI, − 0.88 to − 0.4; P < 0.00001;Chi-2 = 4.86; I2 = 38%). Conclusions Culture positivity or negativity was not associated with mortality of sepsis or septic shock patients. Furthermore, culture-positive septic patients had similar ICU length of stay, mechanical ventilation requirements and renal replacement requirements as those culture-negative patients. The hospital length of stay and mechanical ventilation duration of culture-positive septic patients were both longer than that of the culture-negative patients. Further large-scale studies are still required to confirm these results.

Abstract Abstract Background : The use of dexmedetomidine for sedation post-cardiac surgery is controversial compared to the use of propofol. Methods : A computerized search on Medline, EMBASE, Web of Science, and Agency for Healthcare Research and Quality databases was performed for up to July 2019. Trials evaluating the efficacy of dexmedetomidine versus propofol in the postoperative sedation of cardiac surgery patients were selected. Primary study outcomes were classified as time-dependent (mechanical ventilation time; time to extubation; length of stay in the intensive care unit and the hospital) and non-time dependent (delirium, bradycardia, and hypotension). Results : Our final analysis included 11 RCTs published between 2003 and 2019 and involved a total of 1184 patients. Time to extubation was significantly reduced in the dexmedetomidine group (Standardized Mean Difference (SMD) = -0.61, 95% Confidence Interval (CI): -1.06 to -0.16, p=0.008), however no difference in mechanical ventilation time was observed (SMD= -0.72, 95% CI: -1.60 to 0.15, N.S.). Moreover, the dexmedetomidine group showed a significant reduction in Intensive Care Unit length of stay (SMD= -0.70, 95% CI: -0.98 to -0.42, p=0.0005) this did not translate into a reduced hospital length of stay (SMD= -1.13, 95% CI: -2.43 to 0.16, N.S). For non-time dependent factors: incidence of delirium was unaffected between groups (OR: 0.68, 95% CI: 0.43 to 1.06, N.S.), while the propofol group of patients had higher rates of bradycardia (OR: 3.39, 95% CI: 1.20 to 9.55, p=0.020) and hypotension (OR: 1.68, 95% CI: 1.09 to 2.58, p=0.017). Conclusion : Despite the ICU time advantages afforded by dexmedetomidine over propofol, the former does not contribute to an overall reduction in hospital length of stay or an overall improvement in postoperative outcomes for heart valve surgery and CABG patients. Time-dependent outcomes confounded by several factors including variability in staff, site-protocols, and complication rates between individual surgical cases.

Objective: The objective of this study was to examine the impact of timely treatment and identification of sepsis on patient outcomes at Sutter Health, a mixed-payer healthcare system in northern California, US. Methods: This observational, retrospective analysis considered electronic health record (EHR) data for individuals who presented with sepsis during 2016-17 at any of Sutter Health's 22 emergency departments (ED). Impacts were assessed for the timing of broad-spectrum antibiotic and intravenous (IV) fluid initiation, first vital signs, sepsis screening, and lactate results. Outcomes were in-hospital mortality, hospital length of stay (LOS) and intensive care unit (ICU) hours for patients discharged alive. Results: The final sample size was 35,847 (N=9,638 severe sepsis, N=5,309 septic shock). Early fluid initiation had the largest estimated impacts: a mortality reduction of 2.85%[2.03%,3.68%] overall and 2.94%[1.44%,4.48%] for severe sepsis (within 1 hour of sepsis presentation), and 14.66%[9.23%,20.07%] for septic shock (within 3 hours); reduced LOS (days) 1.39[1.08,1.71] overall, 2.30[1.31,3.21] severe sepsis, 3.07[1.21,4.94] septic shock; and fewer ICU hours 25.93[16.95,34.66] overall, 35.06[14.7,56.99] severe sepsis, 41.99[15.70,70.68] septic shock (within 3 hours). Sepsis screening within 30 minutes was also associated with mortality reductions (3.88%[2.96%,4.90%] overall, 1.74%[0.08%,3.50%] severe sepsis, 6.78%[3.12%,10.33%] septic shock). The greatest improvement opportunity was estimated for joint initiation of antibiotics and IV fluids, with a modest additional mortality reduction of 0.80%[0.47%,1.17%] overall, 0.77%[0.34%,1.19%] severe sepsis, 2.94%[1.83%,3.97%] septic shock; LOS reduction of 0.37[0.28,0.46] overall, 0.29[0.17,0.43] severe sepsis, 0.25[0.01,0.51] septic shock (within 1 hour); ICU hours reduction of 4.85[3.26,6.57] overall, 5.07[2.55,7.67] severe sepsis, 3.85[1.69,6.24] septic shock (within 3 hours).
