Impact of delayed admission to intensive care units on mortality of critically ill patients: a cohort study

C19TM: A nurse practitioner and physician assistant-led telemonitoring initiative ensures timely transfer of critically ill coronavirus disease 2019 patients

ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic has required swift implementation of innovative practices in health care across the globe. We describe a nurse practitioner (NP) and physician assistant (PA)-led initiative to implement telemonitoring (TM) of noncritical patients with COVID-19 by critical care NPs and PAs (C19TM) for early detection of decompensation and early transfer to the intensive care unit (ICU). Every hospitalized patient with suspected or confirmed COVID-19 received an initial telemedicine consult with a critical care NP or PA. Patients were subsequently monitored via electronic health record once every 12-hour shift for the following indicators: oxygen modality and flow, increase in oxygen requirements, sustained tachypnea, and hemodynamic instability. If signs of decompensation were noted, the NP/PA would remotely reassess the patient, provide recommendations to the hospital internal medicine team, and transfer the patient to the ICU. The primary goal was to avoid cardiopulmonary deterioration requiring aerosol-generating procedures outside of the ICU. Over 65 days, 113 patients (86 suspected and 27 confirmed) were enrolled in C19TM. As a result, there were 13 transfers to the ICU, none of which required an aerosol-generating procedure outside of the ICU.

In-hospital mortality from severe COVID-19 in a tertiary care center in Mexico City; causes of death, risk factors and the impact of hospital saturation

BACKGROUND

As the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has remained in Latin America, Mexico has become the third country with the highest death rate worldwide. Data regarding in-hospital mortality and its risk factors, as well as the impact of hospital overcrowding in Latin America has not been thoroughly explored.

METHODS AND FINDINGS

In this prospective cohort study, we enrolled consecutive adult patients hospitalized with severe confirmed COVID-19 pneumonia at a SARS-CoV-2 referral center in Mexico City from February 26th, 2020, to June 5th, 2020. A total of 800 patients were admitted with confirmed diagnosis, mean age was 51.9 ± 13.9 years, 61% were males, 85% were either obese or overweight, 30% had hypertension and 26% type 2 diabetes. From those 800, 559 recovered (69.9%) and 241 died (30.1%). Among survivors, 101 (18%) received invasive mechanical ventilation (IMV) and 458 (82%) were managed outside the intensive care unit (ICU); mortality in the ICU was 49%. From the non-survivors, 45.6% (n = 110) did not receive full support due to lack of ICU bed availability. Within this subgroup the main cause of death was acute respiratory distress syndrome (ARDS) in 95% of the cases, whereas among the non-survivors who received full (n = 105) support the main cause of death was septic shock (45%) followed by ARDS (29%). The main risk factors associated with in-hospital death were male sex (RR 2.05, 95% CI 1.34-3.12), obesity (RR 1.62, 95% CI 1.14-2.32)-in particular morbid obesity (RR 3.38, 95%CI 1.63-7.00)-and oxygen saturation < 80% on admission (RR 4.8, 95%CI 3.26-7.31).

CONCLUSIONS

In this study we found similar in-hospital and ICU mortality, as well as risk factors for mortality, compared to previous reports. However, 45% of the patients who did not survive justified admission to ICU but did not receive IMV / ICU care due to the unavailability of ICU beds. Furthermore, mortality rate over time was mainly due to the availability of ICU beds, indirectly suggesting that overcrowding was one of the main factors that contributed to hospital mortality.

A Systematic Review of Clinical Outcomes Associated With Intrahospital Transitions

Previous transitional care research has focused on transitions occurring between community and hospital settings. Little is known regarding intrahospital transitions and how they affect care quality. A systematic review was therefore conducted to synthesize the literature regarding clinical outcomes associated with intrahospital transitions. Literature published between January 2003 and December 2018 and indexed in Medline/PubMed, CINAHL, and PsychINFO were reviewed using PRISMA guidelines. Articles were limited to English language and peer-reviewed. Articles were excluded if they focused on transitions occurring from or to the hospital, discharge/discharge planning, or postdischarge follow-up. Data abstraction included study characteristics, sample characteristics, and reported clinical outcomes. Fourteen studies met inclusion criteria, primarily using cross-sectional, cohort, or retrospective chart review quantitative designs. Data were analyzed and synthesized based on outcomes reported. Major outcomes emerging from the articles included delirium, hospital length of stay, mortality, and adverse events. Delirium, hospital length of stay, and morbidity and mortality rates were associated with delayed transfers and transfers to inappropriate units. In addition, increased fall risk and infection rates were associated with higher rates of transfer. Intrahospital transitions represent critical periods of time where the quality of care being provided may be diminished, negatively affecting patient safety and outcomes.

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2020 (J-SSCG 2020)

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2020 (J-SSCG 2020), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created as revised from J-SSCG 2016 jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in September 2020 and published in February 2021. An English-language version of these guidelines was created based on the contents of the original Japanese-language version. The purpose of this guideline is to assist medical staff in making appropriate decisions to improve the prognosis of patients undergoing treatment for sepsis and septic shock. We aimed to provide high-quality guidelines that are easy to use and understand for specialists, general clinicians, and multidisciplinary medical professionals. J-SSCG 2016 took up new subjects that were not present in SSCG 2016 (e.g., ICU-acquired weakness [ICU-AW], post-intensive care syndrome [PICS], and body temperature management). The J-SSCG 2020 covered a total of 22 areas with four additional new areas (patient- and family-centered care, sepsis treatment system, neuro-intensive treatment, and stress ulcers). A total of 118 important clinical issues (clinical questions, CQs) were extracted regardless of the presence or absence of evidence. These CQs also include those that have been given particular focus within Japan. This is a large-scale guideline covering multiple fields; thus, in addition to the 25 committee members, we had the participation and support of a total of 226 members who are professionals (physicians, nurses, physiotherapists, clinical engineers, and pharmacists) and medical workers with a history of sepsis or critical illness. The GRADE method was adopted for making recommendations, and the modified Delphi method was used to determine recommendations by voting from all committee members. As a result, 79 GRADE-based recommendations, 5 Good Practice Statements (GPS), 18 expert consensuses, 27 answers to background questions (BQs), and summaries of definitions and diagnosis of sepsis were created as responses to 118 CQs. We also incorporated visual information for each CQ according to the time course of treatment, and we will also distribute this as an app. The J-SSCG 2020 is expected to be widely used as a useful bedside guideline in the field of sepsis treatment both in Japan and overseas involving multiple disciplines.

Rapid deployment of an emergency department-intensive care unit for the COVID-19 pandemic

The coronavirus disease 2019 (COVID-19) pandemic mandated rapid, flexible solutions to meet the anticipated surge in both patient acuity and volume. This paper describes one institution’s emergency department (ED) innovation at the center of the COVID-19 crisis, including the creation of a temporary ED–intensive care unit (ICU) and development of interdisciplinary COVID-19–specific care delivery models to care for critically ill patients. Mount Sinai Hospital, an urban quaternary academic medical center, had an existing five-bed resuscitation area insufficiently rescue due to its size and lack of negative pressure rooms. Within 1 week, the ED-based observation unit, which has four negative pressure rooms, was quickly converted into a COVID-19–specific unit, split between a 14-bed stepdown unit and a 13-bed ED-ICU unit. An increase in staffing for physicians, physician assistants, nurses, respiratory therapists, and medical technicians, as well as training in critical care protocols and procedures, was needed to ensure appropriate patient care. The transition of the ED to a COVID-19–specific unit with the inclusion of a temporary expanded ED-ICU at the beginning of the COVID-19 pandemic was a proactive solution to the growing challenges of surging patients, complexity, and extended boarding of critically ill patients in the ED. This pandemic underscores the importance of ED design innovation with flexible spacing, interdisciplinary collaborations on structure and services, and NP ventilation systems which will remain important moving forward.

Effect of emergency critical care nurses and emergency department boarding time on in-hospital mortality in critically ill patients

STUDY HYPOTHESIS

We hypothesized that establishing a program of specialized emergency critical care (ECC) nurses in the ED would improve mortality of ICU patients boarding in the ED.

METHODS

This was a retrospective before-after cohort study using electronic health record data at an academic medical center. We compared in-hospital mortality between the pre- and post-intervention periods and between non-prolonged (≤6 h) boarding time and prolonged (>6 h) boarding time. In-hospital mortality was stratified by illness severity (eccSOFA category) and adjusted using logistic regression.

RESULTS

Severity-adjusted in-hospital mortality decreased from 12.8% pre-intervention to 12.3% post-intervention (-0.5% (95% CI, -3.1% to 2.1%), which was not statistically significant. This was despite a concurrent increase in ED and hospital crowding. The proportion of ECC patients downgraded to a lower level of care while still in the ED increased from 6.4% in the pre-intervention period to 17.0% in the post-intervention period. (+10.6%, 8.2% to 13.0%, p < 0.001). Severity-adjusted mortality was 12.8% in the non-prolonged group vs. 11.3% in the prolonged group (p = 0.331).

CONCLUSIONS

During the post-intervention period, there was a significant increase in illness severity, hospital congestion, ED boarding time, and downgrades in the ED, but no significant change in mortality. These findings suggest that ECC nurses may improve the safety of boarding ICU patients in the ED. Longer ED boarding times were not associated with higher mortality in either the pre- or post-intervention periods.

Changes in the incidence and outcome of multiple organ failure in emergency non-cardiac surgical admissions: a 10-year retrospective observational study

BACKGROUND

During the past decades, epidemiologic data of independent predictors of multiple organ failure (MOF), incidence, and mortality have changed. The aim of the study was to assess the potential changes in the incidence and outcomes of MOF for one decade (2008-2017). In addition, resource utilization was considered.

METHODS

Patients were eligible for inclusion if they were adults, admitted to the ICU between January 1, 2008 and December 31, 2017, and had complete data sets regarding MOF. MOF was defined as organ failure separately with and without central nervous system (CNS) failure. The onset of MOF was defined as being early (≤48 h of ICU admission) and late (>48 h after ICU admission).

RESULTS

Of a total of 13,270 patients enclosed in this study, 44.6% of the patients developed MOF with and 31.4% without CNS failure. MOF-related mortality decreased in patients with (adjusted IRR 0.972 [95% CI 0.948 to 0.996], P=0.022) and without (adjusted IRR 0.957 [95% CI 0.931 to 0.983], P=0.0013) CNS failure. In addition, the incidence (adjusted IRR 0.970 [95% CI 0.950 to 0.991], P=0.006) and mortality (adjusted IRR 0.968 [95% CI 0.940 to 0.996], P=0.025) of early-onset MOF decreased, while the incidence and mortality of late-onset MOF remained constant. The length of ICU (P=0.024) and hospital (P=0.032) stays decreased while the length of mechanical ventilation remained constant (P=0.41).

CONCLUSIONS

Despite all improvements in intensive care during the last decades, the incidence of late-onset MOF remains a resource-intensive, morbid, and lethal condition. More research on etiologies, signs of organ failure, and where and when to start treatment is needed to improve the prognosis of late-onset MOF.

Reduction of in-hospital cardiac arrest with sequential deployment of rapid response team and medical emergency team to the emergency department and acute care wards

Purpose

This study aimed to determine if sequential deployment of a nurse-led Rapid Response Team (RRT) and an intensivist-led Medical Emergency Team (MET) for critically ill patients in the Emergency Department (ED) and acute care wards improved hospital-wide cardiac arrest rates.

Methods

In this single-center, retrospective observational cohort study, we compared the cardiac arrest rates per 1000 patient-days during two time periods. Our hospital instituted a nurse-led RRT in 2012 and added an intensivist-led MET in 2014. We compared the cardiac arrest rates during the nurse-led RRT period and the combined RRT-MET period. With the sequential approach, nurse-led RRT evaluated and managed rapid response calls in acute care wards and if required escalated care and co-managed with an intensivist-led MET. We specifically compared the rates of pulseless electrical activity (PEA) in the two periods. We also looked at the cardiac arrest rates in the ED as RRT-MET co-managed patients with the ED team.

Results

Hospital-wide cardiac arrests decreased from 2.2 events per 1000 patient-days in the nurse-led RRT period to 0.8 events per 1000 patient-days in the combined RRT and MET period (p-value = 0.001). Hospital-wide PEA arrests and shockable rhythms both decreased significantly. PEA rhythms significantly decreased in acute care wards and the ED.

Conclusion

Implementing an intensivist-led MET-RRT significantly decreased the overall cardiac arrest rate relative to the rate under a nurse-led RRT model. Additional MET capabilities and early initiation of advanced, time-sensitive therapies likely had the most impact.

Association of an Emergency Department-embedded Critical Care Unit with Hospital Outcomes and Intensive Care Unit Use

Rationale: A small but growing number of hospitals are experimenting with emergency department-embedded critical care units (CCUs) in an effort to improve the quality of care for critically ill patients with sepsis and acute respiratory failure (ARF).Objectives: To evaluate the potential impact of an emergency department-embedded CCU at the Hospital of the University of Pennsylvania among patients with sepsis and ARF admitted from the emergency department to a medical ward or intensive care unit (ICU) from January 2016 to December 2017.Methods: The exposure was eligibility for admission to the emergency department-embedded CCU, which was defined as meeting a clinical definition for sepsis or ARF and admission to the emergency department during the intervention period on a weekday. The primary outcome was hospital length of stay (LOS); secondary outcomes included total emergency department plus ICU LOS, hospital survival, direct admission to the ICU, and unplanned ICU admission. Primary interrupted time series analyses were performed using ordinary least squares regression comparing monthly means. Secondary retrospective cohort and before-after analyses used multivariable Cox proportional hazard and logistic regression.Results: In the baseline and intervention periods, 3,897 patients met the inclusion criteria for sepsis and 1,865 patients met the criteria for ARF. Among patients admitted with sepsis, opening of the emergency department-embedded CCU was not associated with hospital LOS (β = -1.82 d; 95% confidence interval [CI], -4.50 to 0.87; P = 0.17 for the first month after emergency department-embedded CCU opening compared with baseline; β = -0.26 d; 95% CI, -0.58 to 0.06; P = 0.10 for subsequent months). Among patients admitted with ARF, the emergency department-embedded CCU was not associated with a significant change in hospital LOS for the first month after emergency department-embedded CCU opening (β = -3.25 d; 95% CI, -7.86 to 1.36; P = 0.15) but was associated with a 0.64 d/mo shorter hospital LOS for subsequent months (β = -0.64 d; 95% CI, -1.12 to -0.17; P = 0.01). This result persisted among higher acuity patients requiring ventilatory support but was not supported by alternative analytic approaches. Among patients admitted with sepsis who did not require mechanical ventilation or vasopressors in the emergency department, the emergency department-embedded CCU was associated with an initial 9.9% reduction in direct ICU admissions in the first month (β = -0.099; 95% CI, -0.153 to -0.044; P = 0.002), followed by a 1.1% per month increase back toward baseline in subsequent months (β = 0.011; 95% CI, 0.003-0.019; P = 0.009). This relationship was supported by alternative analytic approaches and was not seen in ARF. No associations with emergency department plus ICU LOS, hospital survival, or unplanned ICU admission were observed among patients with sepsis or ARF.Conclusions: The emergency department-embedded CCU was not associated with clinical outcomes among patients admitted with sepsis or ARF. Among less sick patients with sepsis, the emergency department-embedded CCU was initially associated with reduced rates of direct ICU admission from the emergency department. Additional research is necessary to further evaluate the impact and utility of the emergency department-embedded CCU model.

Persistently elevated early warning scores and lactate identifies patients at high risk of mortality in suspected sepsis

OBJECTIVE

In the UK, the National Early Warning Score (NEWS) is recommended as part of screening for suspicion of sepsis. Is a change in NEWS a better predictor of mortality than an isolated score when screening for suspicion of sepsis?.

METHODS

A prospectively gathered cohort of 1233 adults brought in by ambulance to two UK nonspecialist hospitals, with suspicion of sepsis at emergency department (ED) triage (2015-2017) was analysed. Associations with 30-day mortality and ICU admission rate were compared between groups with an isolated NEWS ≥5 points prehospital and those with persistently elevated NEWS prehospital, in ED and at ward admission. The effect of adding the ED (venous or arterial) lactate was also assessed.

RESULTS

Mortality increased if the NEWS persisted ≥5 at ED arrival 22.1% vs. 10.2% [odds ratio (OR) 2.5 (1.6-4.0); P < 0.001]. Adding an ED lactate ≥2 mmol/L was associated with an increase in mortality greater than for NEWS alone [32.2% vs. 13.3%, OR 3.1 (2.2-4.1); P < 0.001], and increased ICU admission [13.9% vs. 3.7%, OR 3.1 (2.2-4.3); P < 0.001]. If NEWS remained ≥5 at ward admission (predominantly within 4 h of ED arrival), mortality was 32.1% vs. 14.3%, [OR 2.8 (2.1-3.9); P < 0.001] and still higher if accompanied by an elevated ED lactate [42.1% vs. 16.4%, OR 3.7 (2.6-5.3); P < 0.001].

CONCLUSION

Persistently elevated NEWS, from prehospital through the ED to the time of ward admission, combined with an elevated ED lactate identifies patients with suspicion of sepsis at highest risk of in-hospital mortality.

Reduction of early inpatient transfers and rapid response team calls after implementation of an emergency department intake huddle process

Patients admitted to the hospital and requiring a subsequent transfer to a higher level of care have increased morbidity, mortality and length of stay compared with patients who do not require a transfer during their hospital stay. We identified that a high number of patients admitted to our intermediate care (IMC) unit required a rapid response team (RRT) call and an early (<24 hours) transfer to the intensive care unit (ICU). A quality improvement project was initiated with the goal to reduce subsequent early transfers to the ICU and RRT calls. We started by focusing on IMC patients, implementing acuity-based nursing assignments and standardised daily nursing rounds in the IMC aiming to reduce early patient transfers to the ICU. Then, we expanded to all patients admitted to a hospital medical unit from the emergency department (ED), targeting patients with gastrointestinal (GI) bleed and sepsis who were at a higher risk for early transfer to the ICU. We then created an ED intake huddle process that over time was refined to target patients with SIRS criteria with an elevated serum lactic acid level greater than 2.0 mmol/L or a GI bleed with a haematocrit value less than 24%. These interventions resulted in an 10.8 percentage points (31.7% (225/710) to 20.9% (369/1764)) decrease in the early transfers to the ICU for all hospital medicine patients admitted to the hospital from the ED. Mean RRT calls/day decreased by 17%, from 3.0 mean calls/day preintervention to 2.5 mean calls/day postintervention. These quality improvement initiatives have sustained successful outcomes for over 6 years due to integrating enhanced team communication as organisational cultural norm that has become the standard.

A Longer Route to the PICU Can Lead to a Longer Stay in the PICU: A Single-Center Retrospective Cohort Study

INTRODUCTION

Admission to the pediatric ICU versus general pediatric floor for patients is a significant triage decision for emergency department physicians. Escalation of care within 24 hours of hospital admission is considered as a quality metric for pediatric E.R. There exists, however, a lack of data to show that such escalation leads to a poor outcome.

METHODS

A retrospective cohort study was conducted to compare outcomes of patients who required escalation of care within 24 hours of hospital admission to the pediatric ICU (cases) from 01/01 2015 to 02/28 2019 with those who were directly admitted from emergency department to the PICU (controls). A total of 327 cases were compared to 931 controls. Univariate and multivariable regression analysis was done to compare the length of stay and mortality data.

RESULTS

Patients who required escalation of care were significantly younger (median age 1.9 years compared to 4.6 years for controls) and had lower severity of illness score (PIM 3). Cases had a much higher proportion of respiratory diagnosis. ICU length of stay, hospital length of stay and the direct cost was significantly higher for cases compared to controls. This difference persisted for all age groups and respiratory diagnosis. The cost of care, however, was only different for 1-5 years and >5 years age groups. The difference in ICU length of stay (Δ11.1%) and hospital length of stay (Δ7.8%) persisted on multivariate regression analysis after controlling for age, sex, PIM3 score, and diagnostic variables. There was no difference in mortality on the univariate or multivariate analysis between the 2 groups.

CONCLUSIONS

Patients who required escalation of care within 24 hours of hospital admissions have more prolonged ICU and hospital stay and potentially increased cost of care. This measure should be considered while making patient disposition decisions in the emergency department.

How the high acuity unit changes mortality in the intensive care unit: a retrospective before-and-after study

PURPOSE

High acuity units (HAU) are hospital units that provide patients with more acute care and closer monitoring than a general hospital ward but are not as resource intensive as an intensive care unit (ICU). Nevertheless, the impact of opening a HAU on ICU patient outcomes remains poorly defined. We investigated how the creation of a HAU impacted patient outcomes in the ICU.

METHODS

This historical cohort study compared ICU patient in-hospital mortality, ICU length of stay (LOS), and hospital LOS before and after the creation of a HAU in a tertiary-care hospital with a medical/surgical ICU between 1 January 2013 and 31 December 2017.

RESULTS

Data from 4,380 patients (984 in the pre-HAU group and 3,396 in the post-HAU group) were analyzed. In this cohort of ICU patients, 360 (37%) died in the pre-HAU group before the creation of a HAU, and 1,074 (32%) died in the post-HAU group after the creation of a HAU. The creation of a HAU was associated with lower relative risk of in-hospital mortality (adjusted risk ratio, 0.80; 95% confidence interval [CI], 0.72 to 0.89; P < 0.001). The creation of a HAU was also associated with reduced ICU and hospital LOS with a 12% increase in the rate of ICU discharge (adjusted sub-distribution hazard ratio [SHR], 1.12; 95% CI, 1.02 to 1.23; P = 0.02) and a 26% increase in the rate of hospital discharge (adjusted SHR, 1.26; 95% CI, 1.14 to 1.39; P < 0.001), when accounting for the competing risk of death.

CONCLUSIONS

These data support the hypothesis that the creation of a HAU may be associated with reduced in-hospital mortality, ICU LOS, and hospital LOS for ICU patients.

Predictors of Delayed Recognition of Critical Illness in Emergency Department Patients and Its Effect on Morbidity and Mortality

PURPOSE

Timely recognition of critical illness is associated with improved outcomes, but is dependent on accurate triage, which is affected by system factors such as workload and staffing. We sought to first study the effect of delayed recognition on patient outcomes after controlling for system factors and then to identify potential predictors of delayed recognition.

METHODS

We conducted a retrospective cohort study of Emergency Department (ED) patients admitted to the Intensive Care Unit (ICU) directly from the ED or within 48 hours of ED departure. Cohort characteristics were obtained through electronic and standardized chart abstraction. Operational metrics to estimate ED workload and volume using census data were matched to patients' ED stays. Delayed recognition of critical illness was defined as an absence of an ICU consult in the ED or declination of ICU admission by the ICU team. We employed entropy-balanced multivariate models to examine the association between delayed recognition and development of persistent organ dysfunction and/or death by hospitalization day 28 (POD+D), and multivariable regression modeling to identify factors associated with delayed recognition.

RESULTS

Increased POD+D was seen for those with delayed recognition (OR 1.82, 95% CI 1.13-2.92). When the delayed recognition was by the ICU team, the patient was 2.61 times more likely to experience POD+D compared to those for whom an ICU consult was requested and were accepted for admission. Lower initial severity of illness score (OR 0.26, 95% CI 0.12-0.53) was predictive of delayed recognition. The odds for delayed recognition decreased when ED workload is higher (OR 0.45, 95% CI 0.23-0.89) compared to times with lower ED workload.

CONCLUSIONS

Increased POD+D is associated with delayed recognition. Patient and system factors such as severity of illness and ED workload influence the odds of delayed recognition of critical illness and need further exploration.

Impact of early ICU admission on outcome of critically ill and critically ill cancer patients: A systematic review and meta-analysis

OBJECTIVE

Prognostic impact of early ICU admission remains controversial. The aim of this review was to investigate the impact of early ICU admission in the general ICU population and in critically ill cancer patients and to report level of evidences of this later.

METHODS

Systematic review and meta-analysis performed on articles published between 1970 and 2017. Two authors extracted data. Influence of early ICU admission on mortality is reported as Risk Ratio (95%CI) using both fixed and random-effects model.

DATA SYNTHESIS

For general ICU population, 31 studies reporting on 73,213 patients were included (including 66,797 patients with early ICU admission) and for critically ill cancer patients 14 studies reporting on 2414 patients (including 1272 with early ICU admission) were included. Early ICU admission was associated with decreased mortality using a random effect model (RR 0.65; 95% confidence interval 0.58-0.73; I² = 66%) in overall ICU population as in critically ill cancer patients (RR 0.69; 95% confidence interval 0.52-0.90; I² = 85%). To explore heterogeneity, a meta-regression was performed. Characteristics of the trials (prospective vs. retrospective, monocenter vs. multicenter) had no impact on findings. Publication after 2010 (median publication period) was associated with a lower effect of early ICU admission (estimate 0.37; 95%CI 0.14-0.60; P = 0.002) in the general ICU population. A significant publication bias was observed.

CONCLUSION

Theses results suggest that early ICU admission is associated with decreased mortality in the general ICU population and in CICP. These results were however obtained from high risk of bias studies and a high heterogeneity was noted. Systematic review registration: PROSPERO 2018 CRD42018094828.

Identifying 'at-risk' critically ill patients who present to the emergency department and require intensive care unit admission: A retrospective observational cohort study

BACKGROUND

Emergency department (ED) triage is the process of prioritising patients by medical urgency. Delays in intensive care unit (ICU) admission can adversely affect patients.

OBJECTIVES

This study aimed to identify characteristics associated with ICU admission for patients triaged as Australasian Triage Scale (ATS) 3 but subsequently admitted to the ICU within 24 h of triage.

METHODS

This retrospective, observational cohort study was conducted in a public teaching hospital in Queensland, Australia. Patients older than 18 y triaged with an ATS 3 and admitted to the ICU within 24 h of triage or admitted to the ward between January 1, 2012, and December 31, 2012, were included. The demographic and clinical profiles of ICU admissions vs. all other ward admissions for patients triaged an ATS of 3 were compared. Multivariable regression analysis compared characteristics of patients triaged with an ATS of 3 who did and did not require ICU transfer. Descriptive data are reported as n (%) and median and interquartile range (IQR). Regression analysis is reported as adjusted odds ratios (aORs) with 95% confidence intervals (95% CIs).

RESULTS

Of the 27 454 adult ED presentations triaged with an ATS of 3, 22.4% (n = 6138) required hospital admission, comprising 5302 individuals, 2.1% of whom (n = 110) were admitted to the ICU within 24 h of triage. Age- and sex-adjusted predictors of ICU admission for patients triaged with an ATS of 3 included infectious (aOR: 3.7; 95% CI: 2.0-6.9), neurological (aOR: 2.8; 95% CI: 1.6-5.0), and gastrointestinal disorders (aOR: 2.2; 95% CI 1.2-3.5); arriving by ambulance; arriving after hours; or arriving on weekends. Regardless of diagnosis or sex, persons older than 80 y were less likely to be admitted to the ICU (aOR: 0.4; 95% CI: 0.2-0.8).

CONCLUSIONS

Patients triaged as ATS 3 presenting on weekends or after hours, and those with infectious, gastrointestinal, or neurological conditions warrant careful attention as these factors were associated with higher odds of ICU admission. Ongoing staff education regarding triage and signs of deterioration are important to prevent avoidable outcomes.

Association of Premorbid Blood Pressure with Vasopressor Infusion Duration in Patients with Shock

Rationale: Guidelines for vasopressor titration suggest a universal target-mean arterial pressure (MAP) >65 mm Hg. The implications for patients with premorbid low/high blood pressure are unknown.Objectives: To investigate the relationship between premorbid blood pressure and vasopressor duration for patients with shock.Methods: We performed a retrospective cohort study of adults admitted with shock to Calgary ICUs (June 2012-December 2018). The primary exposure was premorbid blood pressure: low (systolic <100); normal (systolic 100-139 and diastolic <90); and high (systolic ≥140 or diastolic ≥90). The primary outcome was vasopressor duration; secondary outcomes included ICU/hospital length of stay and ICU/hospital mortality. We examined associations of premorbid blood pressure with vasopressor duration and length of stay using multivariable competing risk models and mortality using multivariable mixed-effects logistic regression.Measurements and Main Results: Of 3,542 admissions with shock, 177 (5.0%) had premorbid low, 2,887 (81.5%) normal, and 478 (13.5%) high blood pressure. Premorbid low admissions had lower MAPs (vs. normal or high premorbid admissions) over the duration of vasopressor use (P = 0.003) and were maintained nearest premorbid MAPs while receiving vasopressors (P < 0.001). After adjustment, premorbid low admissions had longer vasopressor use (median, 1.35 d vs. 1.04 d for normal; hazard ratio for discontinuation vs. normal, 0.78 [0.73-0.85]; P < 0.001) and premorbid high admissions had shorter use (median, 0.84 d; hazard ratio, 1.22 [1.12-1.33]; P < 0.001). Premorbid low admissions had longer adjusted length of stay and higher adjusted mortality than premorbid normal admissions.Conclusions: Premorbid blood pressure was inversely associated with vasopressor duration.

Impact of ED Organization with a Holding Area and a Dedicated Team on the Adherence to International Guidelines for Patients with Acute Pulmonary Embolism: Experience of an Emergency Department Organized in Areas of Intensity of Care

Background: Adherence to guidelines by physicians of an emergency department (ED) depends on many factors: guideline and environmental factors; patient and practitioner characteristics; the social-political context. We focused on the impact of the environmental influence and of the patients’ characteristics on adherence to the guidelines. It is our intention to demonstrate how environmental factors such as ED organization more affect adherence to guidelines than the patient’s clinical presentation, even in a clinically insidious disease such as pulmonary embolism (PE). Methods: A single-center observational study was carried out on all patients who were seen at our Department of Emergency and Acceptance from 1 January to 31 December 2017 for PE. For the assessment of adherence to guidelines, we used the European guidelines 2014 and analyzed adherence to the correct use of clinical decision rule (CDR as Wells, Geneva, and YEARS); the correct initiation of heparin therapy; and the management of patients at high risk for short-term mortality. The primary endpoint of our study was to determine whether adherence to the guidelines as a whole depends on patients’ management in a holding area. The secondary objective was to determine whether adherence to the guidelines depended on patient characteristics such as the presence of typical symptoms or severe clinical features (massive pulmonary embolism; organ damage). Results: There were significant differences between patients who passed through OBI and those who did not, in terms of both administration of heparin therapy alone (p = 0.007) and the composite endpoints of heparin therapy initiation and observation/monitoring (p = 0.004), as indicated by the guidelines. For the subgroups of patients with massive PE, organ damage, and typical symptoms, there was no greater adherence to the decision making, administration of heparin therapy alone, and the endpoints of heparin therapy initiation and guideline-based observation/monitoring. Conclusions: Patients managed in an ED holding area were managed more in accordance with the guidelines than those who were managed only in the visiting ED rooms and directly hospitalized from there.

Physician-related factors associated with unscheduled revisits to the emergency department and admission to the intensive care unit within 72 h

Investigation of physician-related causes of unscheduled revisits to the emergency department (ED) within 72 h with subsequent admission to the intensive care unit (ICU) is an important parameter of emergency care quality. Between 2012 and 2017, medical records of all adult patients who visited the ED and returned within 72 h with subsequent ICU admission were retrospectively reviewed by three experienced emergency physicians. Study parameters were categorized into "input" (Patient characteristics), "throughput" (Time spent on first ED visit and seniority of emergency physicians, and "output" (Charlson Comorbidity Index). Of the 147 patients reviewed for the causes of ICU admission, 35 were physician-related (23.8%). Eight belonged to more urgent categories, whereas the majority (n = 27) were less urgent. Patients who spent less time on their first ED visits before discharge (< 2 h) were significantly associated with physician-related causes of ICU admission, whereas there was no significant difference in other "input," "throughput," and "output" parameters between the "physician-related" and "non-physician-related" groups. Short initial management time was associated with physician-related causes of ICU admission in patients with initial less urgent presentations, highlighting failure of the conventional triage system to identify potentially life-threatening conditions and possibility of misjudgement because of the patients' apparently minor initial presentations.

Mortality of Patients Requiring Escalation to Intensive Care within 24 Hours of Admission in a Mixed Medical-Surgical Population

OBJECTIVE

Delayed intensive care unit (ICU) admissions are associated with increased mortality. We present a retrospective study looking at whether indirect admissions to the ICU within 24 hours of hospital admission were associated with increased mortality.

DESIGN

Retrospective cohort study SETTING: Mixed medical-surgical ICU at a large tertiary United States Veterans Affairs (VA) Hospital System POPULATION: The patients were a mix of medical and surgical patients. Patients included both those directly admitted from the operating room as well as those escalated to the ICU after initial admission to the ward (indirect admission).

METHODS

All admissions to a medical-surgical ICU from 2008 to 2013 were included in the study. The database was queried for time and location where the admission originated. Separate lists were created for patients with severe sepsis, patients who transferred to the ICU within the first 24 hours, and patients who had rapid response or code team activations. Analysis was applied to the whole group and to medical and surgical subpopulations.

RESULTS

A total of 3,862 ICU admissions were studied. Univariate analysis indicated an impact of delayed admission on whole group and surgical patients; however, multivariate analysis indicated a significant effect of delayed admission on 1-year surgical mortality. Multivariate analysis also showed a consistent effect of age, ICU length of stay, and cardiac arrest on mortality of both medical and surgical ICU patients.

CONCLUSION

In a large retrospective study, surgical patients had increased 1-year mortality if they required escalation to the ICU within 24 hours of hospital admission. This result was not replicated in medical patients, possibly related to a burden of illness that could not be altered by earlier care.

Boarding of critically Ill patients in the emergency department

OBJECTIVES

Emergency department boarding is the practice of caring for admitted patients in the emergency department after hospital admission, and boarding has been a growing problem in the United States. Boarding of the critically ill has achieved specific attention because of its association with poor clinical outcomes. Accordingly, the Society of Critical Care Medicine and the American College of Emergency Physicians convened a Task Force to understand the implications of emergency department boarding of the critically ill. The objective of this article is to review the U.S. literature on (1) the frequency of emergency department boarding among the critically ill, (2) the outcomes associated with critical care patient boarding, and (3) local strategies developed to mitigate the impact of emergency department critical care boarding on patient outcomes.

DATA SOURCES AND STUDY SELECTION

Review article.

DATA EXTRACTION AND DATA SYNTHESIS

Emergency department-based boarding of the critically ill patient is common, but no nationally representative frequency estimates has been reported. Boarding literature is limited by variation in the definitions used for boarding and variation in the facilities studied (boarding ranges from 2% to 88% of ICU admissions). Prolonged boarding in the emergency department has been associated with longer duration of mechanical ventilation, longer ICU and hospital length of stay, and higher mortality. Health systems have developed multiple mitigation strategies to address emergency department boarding of critically ill patients, including emergency department-based interventions, hospital-based interventions, and emergency department-based resuscitation care units.

CONCLUSIONS

Emergency department boarding of critically ill patients was common and was associated with worse clinical outcomes. Health systems have generated a number of strategies to mitigate these effects. A definition for emergency department boarding is proposed. Future work should establish formal criteria for analysis and benchmarking of emergency department-based boarding overall, with subsequent efforts focused on developing and reporting innovative strategies that improve clinical outcomes of critically ill patients boarded in the emergency department.

Effect of Delayed Admission to Intensive Care Units from the Emergency Department on the Mortality of Critically Ill Patients

Background: Increasing in emergency department need to critical care, the number of intensive care unit bed worldwide is inadequate to meet these applies. Objectives: The aim of this study was to investigate the effect of waiting for admission to the Intensive Care Unit (ICU) in the Emergency Department (ED) on the length of stay in the ICU and the mortality of critically ill patients. Methods: This retrospective cohort study carried out between January 2012 - 2019 patients admitted to the ICU of a training and research hospital. The data of 1297 adult patients were obtained by searching the Clinical Decision Support System. Results: The data of the patients were evaluated in two groups as those considered to be delayed and non-delayed. It was determined that the delay of two hours increased the risk of mortality 1.5 times. Hazard Ratios (HR) was 1.548 (1.077 - 2.224). Patients whose ICU admission was delayed by 5 - 6 hours were found to have the highest risk in terms of mortality (HR = 2.291 [1.503 - 3.493]). A statistically significant difference was found in the ICU mortality, 28-day and, 90-day mortality between the two groups. ICU mortality for all patients’ general was 25.2% (327/1297). This rate was 11.4% (55/481) in the non-delayed group and 33.3% (272/816) in the delayed group (P < 0.001). The 28-day mortality rate for all patients’ general was 26.9% (349/1297). This rate was found to be 13.5% (65/481) in the non-delayed group and 34.8% (284/816) in the delayed group (P < 0.001). The 90-day mortality for all patients’ general was 28.4% (368/1297). This rate was 14.1% (68/481) in the non-delayed group and 36.8% (300/816) in the delayed group (P < 0.001). Conclusions: Prolonged stay in the ED before admission to the ICU is associated with worse consequences, and increased mortality.

Increased Risk for Carbapenem-Resistant Enterobacteriaceae Colonization in Intensive Care Units after Hospitalization in Emergency Department

Carbapenem-resistant Enterobacteriaceae (CRE) colonization is common in hospital patients admitted to intensive care units (ICU) from the emergency department. We evaluated the effect of previous hospitalization in the emergency department on CRE colonization at ICU admission. Our case–control study included 103 cases and 201 controls; cases were patients colonized by CRE at admission to ICU and controls were patients admitted to ICU and not colonized. Risk factors were emergency department stay, use of carbapenem, Simplified Acute Physiology Score, upper digestive endoscopy, and transfer from another hospital. We found that ED stay before ICU admission was associated with CRE colonization at admission to the ICU. Our findings indicate that addressing infection control problems in EDs will help to control carbapenem resistance in ICUs.

Validation of Early Warning Scores at Two Long-Term Acute Care Hospitals

OBJECTIVES

Early warning scores were developed to identify high-risk patients on the hospital wards. Research on early warning scores has focused on patients in short-term acute care hospitals, but there are other settings, such as long-term acute care hospitals, where these tools could be useful. However, the accuracy of early warning scores in long-term acute care hospitals is unknown.

DESIGN

Observational cohort study.

SETTING

Two long-term acute care hospitals in Illinois from January 2002 to September 2017.

PATIENTS

Admitted adult long-term acute care hospital patients.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Demographic characteristics, vital signs, laboratory values, nursing flowsheet data, and outcomes data were collected from the electronic health record. The accuracy of individual variables, the Modified Early Warning Score, the National Early Warning Score version 2, and our previously developed electronic Cardiac Arrest Risk Triage score were compared for predicting the need for acute hospital transfer or death using the area under the receiver operating characteristic curve. A total of 12,497 patient admissions were included, with 3,550 experiencing the composite outcome. The median age was 65 (interquartile range, 54-74), 46% were female, and the median length of stay in the long-term acute care hospital was 27 days (interquartile range, 17-40 d), with an 8% in-hospital mortality. Laboratory values were the best predictors, with blood urea nitrogen being the most accurate (area under the receiver operating characteristic curve, 0.63) followed by albumin, bilirubin, and WBC count (area under the receiver operating characteristic curve, 0.61). Systolic blood pressure was the most accurate vital sign (area under the receiver operating characteristic curve, 0.60). Electronic Cardiac Arrest Risk Triage (area under the receiver operating characteristic curve, 0.72) was significantly more accurate than National Early Warning Score version 2 (area under the receiver operating characteristic curve, 0.66) and Modified Early Warning Score (area under the receiver operating characteristic curve, 0.65; p < 0.01 for all pairwise comparisons).

CONCLUSIONS

In this retrospective cohort study, we found that the electronic Cardiac Arrest Risk Triage score was significantly more accurate than Modified Early Warning Score and National Early Warning Score version 2 for predicting acute hospital transfer and mortality. Because laboratory values were more predictive than vital signs and the average length of stay in an long-term acute care hospital is much longer than short-term acute hospitals, developing a score specific to the long-term acute care hospital population would likely further improve accuracy, thus allowing earlier identification of high-risk patients for potentially life-saving interventions.

Emergency Department to ICU Time Is Associated With Hospital Mortality: A Registry Analysis of 14,788 Patients From Six University Hospitals in The Netherlands

Supplemental Digital Content is available in the text.

Prolonged emergency department to ICU waiting time may delay intensive care treatment, which could negatively affect patient outcomes. The aim of this study was to investigate whether emergency department to ICU time is associated with hospital mortality.

Adverse outcomes of delayed intensive care unit

OBJECTIVE

To examine the impact of delayed transfer from the emergency room into the intensive care unit on the length of intensive care unit stay and death.

METHODS

This prospective, cohort study performed in a tertiary academic hospital obtained data from 1913 patients admitted to the emergency room with a documented request for admission into the intensive care unit. The patients admitted directly into the medical-surgical intensive care unit (n = 209) were categorized into tertiles according to their waiting time for intensive care unit admission (Group 1: < 637 min, Group 2: 637 to 1602 min, and Group 3: > 1602 min). Patients who stayed in the intensive care unit for longer than 3.2 days (median time of intensive care unit length of stay of all patients) were considered as having a prolonged intensive care unit stay.

RESULTS

A total of 6,176 patients were treated in the emergency room during the study period, among whom 1,913 (31%) required a bed in the intensive care unit. The median length of stay in the emergency room was 17 hours [9 to 33 hours]. Hospitalization for infection/sepsis was an independent predictor of prolonged intensive care unit stay (OR 2.75 95%CI 1.38 - 5.48, p = 0.004), but waiting time for intensive care unit admission was not. The mortality rate was higher in Group 3 (38%) than in Group 1 (31%) but the difference was not statistically significant.

CONCLUSION

Delayed admission into the intensive care unit from the emergency room did not result in an increased intensive care unit stay or mortality.

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

PURPOSE

Hospital 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 METHODS

7-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.

RESULTS

Median (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).

CONCLUSIONS

ICU transfer delay exponentially increased above a threshold hospital occupancy and may be associated with increased hospital mortality.

IMPORTANCE

Boarding in the emergency department (ED) is a critical indicator of quality of care for hospitals. It is defined as the time between the admission decision and departure from the ED. As a result of boarding, patients stay in the ED until inpatient beds are available; moreover, boarding is associated with various adverse events.

STUDY OBJECTIVE

The objective of our systematic review was to determine whether ED boarding (EDB) time is associated with in-hospital mortality (IHM).

METHODS

A systematic search was conducted in academic databases to identify relevant studies. Medline, PubMed, Scopus, Embase, Cochrane, Web of Science, Cochrane, CINAHL and PsychInfo were searched. We included all peer-reviewed published studies from all previous years until November 2018. Studies performed in the ED and focused on the association between EDB and IHM as the primary objective were included. Extracted data included study characteristics, prognostic factors, outcomes, and IHM. A search update in PubMed was performed in May 2019 to ensure the inclusion of recent studies before publishing.

RESULTS

From the initial 4,321 references found through the systematic search, the manual screening of reference lists and the updated search in PubMed, a total of 12 studies were identified as eligible for a descriptive analysis. Overall, six studies found an association between EDB and IHM, while five studies showed no association. The last remaining study included both ICU and non-ICU subgroups and showed conflicting results, with a positive association for non-ICU patients but no association for ICU patients. Overall, a tendency toward an association between EDB and IHM using the pool random effect was observed.

CONCLUSION

Our systematic review did not find a strong evidence for the association between ED boarding and IHM but there is a tendency toward this association. Further well-controlled, international multicenter studies are needed to demonstrate whether this association exists and whether there is a specific EDB time cut-off that results in increased IHM.

Association between long boarding time in the emergency department and hospital mortality: a single-center propensity score-based analysis

Once diagnostic work-up and first therapy are completed in patients visiting the emergency department (ED), boarding them within the ED until an in-hospital bed became available is a common practice in busy hospitals. Whether this practice may harm the patients remains a debate. We sought to determine whether an ED boarding time longer than 4 h places the patients at increased risk of in-hospital death. This retrospective, propensity score-matched analysis and propensity score-based inverse probability weighting analysis was conducted in an adult ED in a single, academic, 1136-bed hospital in France. All patients hospitalized via the adult ED from January 1, 2013 to March 31, 2018 were included. Hospital mortality (primary outcome) and hospital length of stay (LOS) were assessed in (1) a matched cohort (1:1 matching of ED visits with or without ED boarding time longer than 4 h but similar propensity score to experience an ED boarding time longer than 4 h); and (2) the whole study cohort. Sensitivity analysis to unmeasured confounding and analyses in pre-specified cohorts of patients were conducted. Among 68,632 included ED visits, 17,271 (25.2%) had an ED boarding time longer than 4 h. Conditional logistic regression performed on a 10,581 pair-matched cohort, and generalized estimating equations with adjustment on confounders and stabilized propensity score-based inverse probability weighting applied on the whole cohort showed a significantly increased risk of hospital death in patients experiencing an ED boarding time longer than 4 h: odds ratio (OR) of 1.13 (95% confidence interval [95% CI] 1.05-1.22), P = 0.001; and OR of 1.12 (95% CI 1.03-1.22), P = 0.007, respectively. Sensitivity analyses showed that these findings might be robust to unmeasured confounding. Hospital LOS was significantly longer in patients exposed to ED boarding time longer than 4 h: median difference 2 days (95% CI 1-2) (P < 0.001) in matched analysis and mean difference 1.15 days (95% CI 1.02-1.28) (P < 0.001) in multivariable unmatched analysis. In this single-center propensity score-based cohort analysis, patients experiencing an ED boarding time longer than 4 h before being transferred to an in-patient bed were at increased risk of hospital death.

Abnormal Vital Signs Predict Critical Deterioration in Hospitalized Pediatric Hematology-Oncology and Post-hematopoietic Cell Transplant Patients

Introduction: Hospitalized pediatric hematology-oncology and post-hematopoietic cell transplant (HCT) patients have frequent deterioration requiring Pediatric Intensive Care Unit (PICU) care. Critical deterioration (CD), defined as unplanned PICU transfer requiring life-sustaining interventions within 12 h, is a pragmatic metric to evaluate emergency response systems (ERS) in pediatrics, however, it has not been investigated in these patients. The goal of this study was to evaluate if CD is an appropriate metric to assess effectiveness of ERS in pediatric hematology-oncology and post-HCT patients and if it is preceded by an actionable period of vital sign changes.

Methods: A retrospective review of all unplanned PICU transfers and floor cardiopulmonary arrests in a dedicated pediatric hematology-oncology hospital between August 2014 and July 2016. Vital signs and physical exam findings 48 h prior to events were converted to Pediatric Early Warning System-Like Scores (PEWS-LS) using cardiovascular, respiratory, and neurologic criteria.

Results: There were 220 deterioration events, with 107 (48.6%) meeting criteria for CD, representing a rate of 2.98 per 1,000-inpatient-days. Using the first event per hospitalization (n = 184), patients with CD had higher mortality (17.4 vs. 7.6%, p = 0.045), fewer median ICU-free-days (21 vs. 24, p = 0.011), ventilator-free-days (25 vs. 28, p < 0.001), and vasoactive-free-days (27 vs. 28, p < 0.001). Using vital sign data 48 h prior to deterioration events, those with CD had higher PEWS-LS on PICU admission (p < 0.001), spent more time with elevated PEWS-LS prior to PICU transfer (p = 0.008 to 0.023) and had a longer time from first abnormal PEWS-LS (p = 0.007 to 0.043). Significant difference between the two groups was observed as early as 4 h prior to the event (p = 0.047).

Conclusion: Hospitalized pediatric hematology-oncology and post-HCT patients have frequent deterioration resulting in a high mortality. In these patients, CD is over 13 times more common than floor cardiopulmonary arrests and associated with higher mortality and fewer event-free days, making it a useful metric in these patients. CD is preceded by a long duration of abnormal vital signs, making it potentially preventable through earlier recognition.

Using sepsis scores in emergency department and ward patients

Sepsis-3, published in 2016, defined sepsis as 'life-threatening organ dysfunction caused by a dysregulated host response to infection'. Instead of systemic inflammatory response syndrome (SIRS), calculating the Sequential Organ Failure Assessment (SOFA) score was recommended. The complexity of SOFA also led to the introduction of quick SOFA (qSOFA) as a bedside tool. The simultaneous removal of SIRS and introduction of qSOFA belies their significant differences, with SIRS having a high sensitivity but very low specificity, and qSOFA being very specific for a poor outcome, but having a lower sensitivity than SIRS. In the UK, the variables within qSOFA are collected on a regular and repeated basis, along with additional variables, as part of the National Early Warning Score (NEWS). A knowledge of SIRS, qSOFA and NEWS is of value in assessing patients with suspected sepsis, as discussed in this article.

A cross sectional survey of factors influencing mortality in Rwandan surgical patients in the intensive care unit

BACKGROUND

Management of critically ill patients is a challenge in low resource settings where there is a paucity of trained staff, infrastructure, resources, and drugs. We aimed to study the characteristics of surgical patients admitted in intensive care unit in a limited resource setting and determine factors associated with mortality.

METHODS

This was a cross-sectional observational study of all surgical patients admitted to the intensive care unit of a tertiary referral hospital in Rwanda. Data included demographics, diagnosis, management, and outcomes. Logistic regression was used to determine factors associated with mortality.

RESULTS

Over a 7-month period, there were 126 surgical patients admitted to the intensive care unit. Common diagnoses included head injury (n = 55, 44%), peritonitis (n = 33, 26%), brain tumor (n = 15, 12%), and trauma (n = 15, 12%). The overall mortality was 47% with the highest mortality seen in patients with peritonitis (76%). Factors associated with mortality on intensive care unit admission included hypotension (odds ratio, 12.50; 95% confidence interval, 3.04, 51.32) and having any comorbidity (odds ratio 5.69, 95% confidence interval, 1.58, 20.50).

CONCLUSION

Surgical patients admitted to the intensive care unit bear a significant mortality. Common surgical intensive care unit diagnoses include head injury and peritonitis. We recommend a review of the admission policy to optimize utility of the intensive care unit.

Seasonal variation of clinical characteristics and prognostic of adult patients admitted to an intensive care unit

OBJECTIVE

To evaluate seasonal variations of clinical characteristics, therapeutic resource use, and outcomes of critically ill patients admitted to an intensive care unit.

METHODS

A retrospective cohort study conducted from January 2011 to December 2016 in adult patients admitted to the intensive care unit (ICU) of a University Hospital. Data were collected on the type of admission, APACHE II, SOFA, and TISS 28 scores at ICU admission. Length of hospital stay and vital status at hospital discharge were recorded. A significance level of 5% was adopted.

RESULTS

During the study period, 3.711 patients were analyzed. Patients had a median age of 60.0 years (interquartile range = 45.0 - 73.0), and 59% were men. The independent risk factors associated with increased hospital mortality rate were age, chronic disease, seasonality, diagnostic category, need for mechanical ventilation and vasoactive drugs, presence of acute kidney injury, and sepsis at admission.

CONCLUSION

It was possible to observe variations of the clinical characteristics and prognosis of patients; summer months presented a higher proportion of clinical and emergency surgery patients, with higher mortality rates. Sepsis at ICU admission did not show seasonal behavior. A seasonal pattern was found for mortality rate.

Triage and flow management in sepsis

Background

Sepsis is a major public health problem, with a growing incidence and mortality rates still close to 30% in severe cases. The speed and adequacy of the treatment administered in the first hours of sepsis, particularly access to intensive care, are important to reduce mortality. This study compared the triage strategies and intensive care rationing between septic patients and patients with other indications of intensive care. This study included all patients with signs for intensive care, enrolled in the intensive care management system of a Brazilian tertiary public emergency hospital, from January 1, 2010, to December 31, 2016. The intensivist periodically evaluated the requests, prioritizing them according to a semi-quantitative scale. Demographic data, Charlson Comorbidity Index (CCI), Sequential Organ Failure Assessment (SOFA), and quick SOFA (qSOFA), as well as surgical interventions, were used as possible confounding factors in the construction of incremental logistic regression models for prioritization and admission to intensive care outcomes.

Results

The study analyzed 9195 ICU requests; septic patients accounted for 1076 cases (11.7%), 293 (27.2%) of which were regarded as priority 1. Priority 1 septic patients were more frequently hospitalized in the ICU than nonseptic patients (52.2% vs. 34.9%, p <  0.01). Septic patients waited longer for the vacancy, with a median delay time of 43.9 h (interquartile range 18.2–108.0), whereas nonseptic patients waited 32.5 h (interquartile range 11.5–75.8)—p <  0.01. Overall mortality was significantly higher in the septic group than in the group of patients with other indications for intensive care (72.3% vs. 39.8%, p <  0.01). This trend became more evident after the multivariate analysis, and the mortality odds ratio was almost three times higher in septic patients (2.7, 2.3–3.1).

Conclusion

Septic patients had a lower priority for ICU admission and longer waiting times for an ICU vacancy than patients with other critical conditions. Overall, this implied a 2.7-fold increased risk of mortality in septic patients.

Emergency physician-based intensive care unit for critically ill patients visiting emergency department

BACKGROUND

To provide a prompt and optimal intensive care to critically ill patients visiting our emergency department (ED), we set up and ran a specific type of emergency intensive care unit (EICU) managed by emergency physician (EP) intensivists. We investigated whether this EICU reduced the time interval from ED arrival to ICU transfer (ED-ICU interval) without altering mortality.

METHODS

This was a retrospective study conducted in a tertiary referral hospital. We collected data from ED patients who were admitted to the EICU (EICU group) and other ICUs including medical, surgical, and cardiopulmonary ICUs (other ICUs group), from August 2014 to July 2017. We compared these two groups with respect to demographic findings, including the Acute Physiology and Chronic Health Evaluation II (APACHE II) score, ED-ICU interval, ICU mortality, and hospital mortality.

RESULTS

Among the 3440 critically ill patients who visited ED, 1815 (52.8%) were admitted to the EICU during the study period. The ED-ICU interval for the EICU group was significantly shorter than that for the other ICUs group by 27.5% (5.0 ± 4.9 vs. 6.9 ± 5.4 h, p < 0.001). In multivariable analysis, the ICU mortality (odds ratio = 1.062, 95% confidence interval 0.862-1.308, p = 0.571) and hospital mortality (odds ratio = 1.093, 95% confidence interval 0.892-1.338, p = 0.391) of the EICU group were not inferior to those of the other ICUs group.

CONCLUSIONS

The EICU run by EP intensivists reduced the time interval from ED arrival to ICU transfer without altering hospital mortality.

Using Quality Improvement Methods to Understand Incidence, Timing, and Factors Associated With Unplanned Intensive Care Unit Transfers of Patients With End-Stage Liver Disease

Introduction:

Patients with end-stage liver disease are at risk for clinical deterioration, often requiring hospital admissions while awaiting transplantation. Nurses observed that many patients were or became unstable soon after arrival, requiring transfers to the medical intensive care unit.

Objective:

To explore the incidence, timing, and factors associated with unplanned intensive care transfers.

Design:

We conducted a quality improvement project using plan-do-study-act methods to explore administrative data from adult patients admitted to the hepatology service’s medical–surgical unit. Chi-square and t-tests were used to examine associations between demographic, clinical, and temporal factors and unplanned transfers. Data were analyzed at the hospital encounter level.

Results:

Unplanned transfers occurred in 8.6% of 1418 encounters. The number of transfers during these encounters ranged from 1 to 6. Most unplanned transfers (65.9%) occurred during the evening shift. On average, there was a 4.2-hour delay to the transfer. Fifty-one percent of these encounters required support from clinicians outside the unit while waiting for a bed. Factors associated with unplanned intensive care unit transfer were male sex ( P = .02), self-referral to the emergency department ( P < .001), and lower initial mean Rothman Index ( P < .001).

Discussion:

Results validated nurses’ concerns about the patients’ severity of illnesses at the time of admission and frequent need for transfer to intensive care soon after admission. We now have actionable data that are being used by leaders to assess unit admission criteria and develop operating budgets for human and material resources needed to care for this challenging population.

Developing an intervention around referral and admissions to intensive care: a mixed-methods study

Background

Intensive care treatment can be life-saving, but it is invasive and distressing for patients receiving it and it is not always successful. Deciding whether or not a patient will benefit from intensive care is a difficult clinical and ethical challenge.

Objectives

To explore the decision-making process for referral and admission to the intensive care unit and to develop and test an intervention to improve it.

Methods

A mixed-methods study comprising (1) two systematic reviews investigating the factors associated with decisions to admit patients to the intensive care unit and the experiences of clinicians, patients and families; (2) observation of decisions and interviews with intensive care unit doctors, referring doctors, and patients and families in six NHS trusts in the Midlands, UK; (3) a choice experiment survey distributed to UK intensive care unit consultants and critical care outreach nurses, eliciting their preferences for factors used in decision-making for intensive care unit admission; (4) development of a decision-support intervention informed by the previous work streams, including an ethical framework for decision-making and supporting referral and decision-support forms and patient and family information leaflets. Implementation feasibility was tested in three NHS trusts; (5) development and testing of a tool to evaluate the ethical quality of decision-making related to intensive care unit admission, based on the assessment of patient records. The tool was tested for inter-rater and intersite reliability in 120 patient records.

Results

Influences on decision-making identified in the systematic review and ethnographic study included age, presence of chronic illness, functional status, presence of a do not attempt cardiopulmonary resuscitation order, referring specialty, referrer seniority and intensive care unit bed availability. Intensive care unit doctors used a gestalt assessment of the patient when making decisions. The choice experiment showed that age was the most important factor in consultants’ and critical care outreach nurses’ preferences for admission. The ethnographic study illuminated the complexity of the decision-making process, and the importance of interprofessional relationships and good communication between teams and with patients and families. Doctors found it difficult to articulate and balance the benefits and burdens of intensive care unit treatment for a patient. There was low uptake of the decision-support intervention, although doctors who used it noted that it improved articulation of reasons for decisions and communication with patients.

Limitations

Limitations existed in each of the component studies; for example, we had difficulty recruiting patients and families in our qualitative work. However, the project benefited from a mixed-method approach that mitigated the potential limitations of the component studies.

Conclusions

Decision-making surrounding referral and admission to the intensive care unit is complex. This study has provided evidence and resources to help clinicians and organisations aiming to improve the decision-making for and, ultimately, the care of critically ill patients.

Future work

Further research is needed into decision-making practices, particularly in how best to engage with patients and families during the decision process. The development and evaluation of training for clinicians involved in these decisions should be a priority for future work.

Referral and admission to intensive care: A qualitative study of doctors' practices in a Tanzanian university hospital

BACKGROUND

Intensive care is care for critically ill patients with potentially reversible conditions. Patient selection for intensive care should be based on potential benefit but since demand exceeds availability, rationing is needed. In Tanzania, the availability of Intensive Care Units (ICUs) is very limited and the practices for selecting patients for intensive care are not known. The aim of this study was to explore doctors' experiences and perceptions of ICU referral and admission processes in a university hospital in Tanzania.

METHODS

We performed a qualitative study using semi-structured interviews with fifteen doctors involved in the recent care of critically ill patients in university hospital in Tanzania. Inductive conventional content analysis was applied for the analysis of interview notes to derive categories and sub-categories.

RESULTS

Two main categories were identified, (i) difficulties with the identification of critically ill patients in the wards and (ii) a lack of structured triaging to the ICU. A lack of critical care knowledge and communication barriers were described as preventing identification of critically ill patients. Triaging to the ICU was affected by a lack of guidelines for admission, diverging ideas about ICU indications and contraindications, the lack of bed capacity in the ICU and non-medical factors such as a fear of repercussions.

CONCLUSION

Critically ill patients may not be identified in general wards in a Tanzanian university hospital and the triaging process for the admission of patients to intensive care is convoluted and not explicit. The findings indicate a potential for improved patient selection that could optimize the use of scarce ICU resources, leading to better patient outcomes.

[Causes, diagnosis and treatments of circulatory shocks]

Shock states are the leading causes of intensive care admission and are nowadays associated with high morbidity and mortality. They are driven by a complex physiopathology and most frequently a multifactorial mechanism. They can be separated in whether a decrease of oxygen delivery (quantitative shock) or an abnormal cell distribution of cardiac output (distributive shock). Septic, cardiogenic and hypovolemic shocks represent more than 80% of shock etiologies. Clinical presentation is mostly characterized by frequent arterial hypotension and sign of poor clinical perfusion. Hyperlactatemia occurs in most of shock states. The diagnostic of shock or earlier reversible "pre-shock" states is urgent in order to initiate adequate therapy. Therefore, orientation and therapies must be discussed with intensive care physiologists in a multidisciplinary approach. Etiologic investigation and correction is a primary concern. Hemodynamic and respiratory support reflect another part of initial therapy toward normalization of cell oxygenation. Fluid resuscitation is the corner stone part of initial therapy of any form of shock. Vasoconstrictive drugs or inotropic support still often remain necessary. The primary goal of initial resuscitation should be not only to restore blood arterial pressure but also to improve clinical perfusion markers. On the biological side, decrease of lactate concentration is associated with better outcome.

Direct admission to the intensive care unit from the emergency department and mortality in critically ill hematology patients

Background

The aim of this study was to assess the benefit of direct ICU admission from the emergency department (ED) compared to admission from wards, in patients with hematological malignancies requiring critical care.

Methods

Post hoc analysis derived from a prospective, multicenter cohort study of 1011 critically ill adult patients with hematologic malignancies admitted to 17 ICU in Belgium and France from January 2010 to May 2011. The variable of interest was a direct ICU admission from the ED and the outcome was in-hospital mortality. The association between the variable of interest and the outcome was assessed by multivariable logistic regression after multiple imputation of missing data. Several sensitivity analyses were performed: complete case analysis, propensity score matching and multivariable Cox proportional-hazards analysis of 90-day survival.

Results

Direct ICU admission from the ED occurred in 266 (26.4%) cases, 84 of whom (31.6%) died in the hospital versus 311/742 (41.9%) in those who did not. After adjustment, direct ICU admission from the ED was associated with a decreased in-hospital mortality (adjusted OR: 0.63; 95% CI 0.45–0.88). This was confirmed in the complete cases analysis (adjusted OR: 0.64; 95% CI 0.45–0.92) as well as in terms of hazard of death within the 90 days after admission (adjusted HR: 0.77; 95% CI 0.60–0.99). By contrast, in the propensity score-matched sample of 402 patients, direct admission was not associated with in-hospital mortality (adjusted OR: 0.92; 95% CI 0.84–1.01).

Conclusions

In this study, patients with hematological malignancies admitted to the ICU were more likely to be alive at hospital discharge if they were directly admitted from the ED rather than from the wards. Assessment of early predictors of poor outcome in cancer patients admitted to the ED is crucial so as to allow early referral to the ICU and avoid delays in treatment initiation and mis-orientation.

Survival and Safety Outcomes of ICU Patients Discharged Directly Home-A Direct From ICU Sent Home Study

OBJECTIVES

Evaluate outcomes (mortality, morbidity, unplanned return visits) of patients who are discharged directly to home from the ICU.

DESIGN

Prospective cohort study.

SETTING

Two tertiary care medical-surgical-trauma ICUs at Canadian hospitals over 1 year (February 2016-2017).

SUBJECTS

All adult patients who were either discharged directly to home (Recruited and Nonrecruited cohorts) from ICU or discharged home within 24 hours after ward transfer (Ward Transfer cohort).

INTERVENTIONS

Direct discharge home from ICU or discharge home within 24 hours of ward transfer from ICU.

MEASUREMENTS AND MAIN RESULTS

One-hundred ninety-eight patients were in the study, 100 patients in the discharged directly to home Recruited arm, 37 patients in the discharged directly to home Nonrecruited arm, and 61 patients in the Ward cohort. All three patient cohorts had 0% mortality at 8 weeks post discharge. The unplanned return visit rate for the Recruited cohort was 24% (emergency department 18%, Ward 4%, ICU 1%), whereas the rate for the Nonrecruited cohort was 52% (emergency department 34%, Ward 14%, ICU 3%) and the Ward Transfer cohort was 46% (emergency department 17%, Ward 26%, ICU 3%) (p = 0.005). No home support was available for 7% of the discharged directly to home Recruited cohort. Twenty-four percent of patients had funded home care nursing, but the majority of patients (81%) relied on help from friends/family.

CONCLUSIONS

Recruited discharged directly to home patients experienced very good 8-week postdischarge outcomes with 0% mortality and a low rate of ICU readmission (1%) or ward readmission (4%), but not an insignificant rate of emergency department visits (18%). Recruited discharged directly to home patients had better outcomes compared with nonrecruited discharged directly to home patients and patients transferred briefly to the ward prior to discharge home. Future work should include derivation of a clinical prediction tool to identify patient characteristics that make discharged directly to home safe and a randomized control trial to compare discharged directly to home with short stay ward transfers.

Should we admit more patients not requiring invasive ventilation to reduce excess mortality in Polish intensive care units? Data from the Silesian ICU Registry

INTRODUCTION

Mortality in Polish intensive care units (ICU) is excessively high. Only a few patients do not require intubation and invasive ventilation throughout the whole ICU treatment period. We aimed to define this population, as pre-emptive admissions of such patients may increase the population which benefits from ICU admission and reduce excessive mortality in Polish ICUs.

MATERIAL AND METHODS

Data on 20 651 patients from the Silesian Registry of Intensive Care Units were analysed. Patients who did not require intubation and invasive ventilation (referred to as non-ventilated patients) were identified and compared to the remaining ICU population. Independent variables that influence being non-intubated in the ICU were identified.

RESULTS

Among 20 368 analyzed adult patients, only 1233 (6.1%) were in the non-ventilated group. Non-ventilated patients were younger, with fewer comorbidities and a lower APACHE II score at admission (13.0 ±7.1 vs. 23.7 ±8.6 points, p < 0.001). Patients with cardiac arrest prior to admission were particularly rare in this group (2.6% vs. 26.8%, p < 0.001). The ICU mortality among non-ventilated patients was 6 to 7 times lower (7.0% vs. 46.7%, p < 0.001). Independent variables that influenced the ICU stay in non-ventilated patients were: obstetric complications as the primary cause of ICU admission, presence of a systemic autoimmune disease, invasive monitoring as the primary cause of ICU admission, ICU readmission and the presence of cancer.

CONCLUSIONS

Non-ventilated patients have a high potential for a favourable outcome. Pre‑emptive ICU admissions have a potential to reduce mortality in Polish ICUs.

The Critical Care Society of Southern Africa Consensus Statement on ICU Triage and Rationing (ConICTri)

Background

In South Africa (SA), intensive care is faced with the challenge of resource scarcity as well as an increasing demand for intensive care unit (ICU) services. ICU services are expensive, and practitioners in low- to middle-income countries experience daily the consequences of limited resources. Critically limited resources necessitate that rationing and triage (prioritisation) decisions are frequently necessary in SA, particularly in the publicly funded health sector.

Purpose

The purpose of this consensus statement is to examine key questions that arise when considering the status of ICU resources in SA, and more specifically ICU admission, rationing and triage decisions. The accompanying guideline in this issue is intended to guide frontline triage policy and ensure the best utilisation of intensive care in SA, while maintaining a fair distribution of available resources. Fair and efficient triage is important to ensure the ongoing provision of high-quality care to adult patients referred for intensive care.

Recommendations

In response to 14 key questions developed using a modified Delphi technique, 29 recommendations were formulated and graded using an adapted GRADE score. The 14 key questions addressed the status of the provision of ICU services in SA, the degree of resource restriction, the efficiency of resource management, the need for triage, and how triage could be most justly implemented. Important recommendations included the need to formally recognise and accurately quantify the provision of ICU services in SA by national audit; actively seek additional resources from governmental bodies; consider methods to maximise the efficiency of ICU care; evaluate lower level of care alternatives; develop a triage guideline to assist policy-makers and frontline practitioners to implement triage decisions in an efficient and fair way; measure and audit the consequence of triage; and promote research to improve the accuracy and consistency of triage decisions. The consensus document and guideline should be reviewed and revised appropriately within 5 years.

Conclusion

In recognition of the absolute need to limit patient access to ICU because of the lack of sufficient intensive care resources in public hospitals, recommendations and a guideline have been developed to guide policy-making and assist frontline triage decision-making in SA. These documents are not a complete plan for quality practice but rather the beginning of a long-term initiative to engage clinicians, the public and administrators in appropriate triage decision-making, and promote systems that will ultimately maximise the efficient and fair use of available ICU resources.

Factors related to delayed intensive care unit admission from emergency department-A retrospective cohort study

BACKGROUND

The delays in transferring patients from emergency department (ED) to intensive care unit (ICU) are known to be linked with several adverse events, including prolonged ICU stay and increased hospital mortality. The factors associated with delayed ICU admission include shortage of ICU beds, organizational factors, ED overcrowding, and patient-related factors, including sepsis as admission diagnosis. The aim of this study was to examine ED-related factors associated with prolonged ED stay.

METHODS

The study population consisted of adult patients admitted (n = 479) from ED to ICU between 31 May 2016 and 19 March 2017 in Oulu University Hospital. A patient's ED length of stay (LOS) exceeding 180 minutes was considered delayed.

RESULTS

Most of the patients (380, 79.3%) were admitted to the ICU within 3 hours of hospital admission. In a logistic regression analysis, odds ratios (ORs) for ED LOS > 180 minutes were as follows: for Glasgow Coma Scale score > 9, 2.73 (1.39-5.32); for thrombocytes < 100 × 10⁹ /mmol, 6.69 (2.32-19.26); for absence of pre-arrival notification, 5.27 (3.04-9.14); and for radiological examination, 3.95 (1.72-9.10). Trauma and intoxicated patients had shorter ED LOS while patients with medical conditions had more often prolonged admissions.

CONCLUSION

The delays in ICU admissions were linked to therapeutic and diagnostic procedures and absence of pre-arrival notification. Patients were admitted to the ICU on the basis of diagnosis instead of clinical risk. However, the delays were not associated with worsening outcome, which indicates that sufficient care can be provided at the ED while the ICU admission is pending.

Intensive Care Role in Disaster Management Critical Care Clinics

The "daily disasters" within the ebb and flow of routine critical care provide a foundation of preparedness for the less-frequent, larger events that affect most health care organizations at some time. Although large disasters can overwhelm, those who strengthen processes and habits through daily practice will be the best prepared to manage them.

TIGER Team: Rapid Response at the University of Missouri

By the end of the 20^th century, health care organizations worldwide were recognizing the benefits of a quick response when patients were experiencing a clinical decline and the difficulty in achieving that goal. The University of Missouri STAT Nurse program, developed in 1989, was an early innovation to deliver the "right care" at the "right time" every time. Over the years, the STAT Nurse program evolved and became the core component of a Rapid Response System. Today Rapid Response at University of Missouri Health Care is called the Targeted Interventional Group Emergency Response Team, also known as the TIGER Team after the much beloved University mascot.

The continuum of critical care

Until relatively recently, critical illness was considered as a separate entity and the intensive care unit (ICU), often a little cut-off from other areas of the hospital, was in many cases used as a last resort for patients so severely ill that it was no longer possible to care for them on the general ward. However, we are increasingly realizing that critical illness should be seen as just one part of the patient's disease trajectory and how the patient is managed before and after ICU admission has an important role to play in optimizing outcomes. Identifying critical illness early, before it reaches a stage where it is life-threatening, is a challenge and requires a combination of improved and more frequent or continuous monitoring of at-risk patients, staff training to recognize when a patient is deteriorating, a system to "call for help," and an effective response to that call. Critical care doctors are now widely available 24 h a day for consultation, and many hospitals have rapid response or medical emergency teams composed of staff trained in intensive care and with resuscitation skills who can attend patients on the ward who have been identified to be deteriorating, assess them to determine the need for ICU admission, and initiate further tests and/or initial therapy. Early intensivist input may also be important for patients undergoing interventions that are likely to result in ICU admission, e.g., transplantation or cardiac surgery. The patient's continuum after ICU discharge must also be taken into account during their ICU stay, with attempts made to limit the longer-term physical and psychological consequences of critical illness as much as possible. Minimal sedation, good communication, and early mobilization are three factors that can help patients survive their ICU stay with minimal sequelae.
