Characteristics, management, and in-hospital mortality among patients with severe sepsis in intensive care units in Japan: the FORECAST study.

This article by Abe and colleagues appeared in the November 2018 issue of Critical Care.
Background:  Sepsis is a leading cause of death and long-term disability in developed countries. A comprehensive report on the incidence, clinical characteristics, and evolving management of sepsis is important. Thus, this study aimed to evaluate the characteristics, management,and outcomes of patients with severe sepsis in Japan.
Methods:  This is a cohort study of the Focused Outcomes Research in Emergency Care in Acute Respiratory Distress Syndrome,Sepsis, and Trauma (FORECAST) study, which was a multicentre, prospective cohort study conducted at 59 intensive care units (ICUs) from January 2016 to March 2017. We included adult patients with severe sepsis based on the sepsis-2 criteria.
Results:  In total, 1184 patients (median age 73 years,inter quartile range (IQR) 64-81) with severe sepsis were admitted to the ICU during the study period. The most common comorbidity was diabetes mellitus(23%). Moreover, approximately 63% of patients had septic shock. The median Sepsis-related Organ Failure Assessment (SOFA) score was 9 (IQR 6-11). The most common site of infection was the lung (31%). Approximately 54% of the participants had positive blood cultures. The compliance rates for the entire 3-h bundle, measurement of central venous pressure, and assessment of central venous oxygen saturation were 64%, 26%, and 7%, respectively. A multi level logistic regression model showed that closed ICUs and non-university hospitals were more compliant with the entire 3-h bundle. The in-hospital mortality rate of patients with severe sepsis was 23% (21-26%). Older age, multiple co-morbidities, suspected site of infection, and increasing SOFA scores correlated with in-hospital mortality, based on the generalized estimating equation model. The length of hospital stay was 24 (12-46) days. Approximately 37% of the patients were discharged home after recovery.
Conclusion:  Our prospective study showed that sepsis management in Japan was characterized by a high compliance rate for the 3-h bundle and low compliance rate for central venous catheter measurements. The in-hospital mortality rate in Japan was comparable to that of other developed countries. Only one third of the patients were discharged home, considering the aging population with multiple co-morbidities in the ICUs in Japan.

TroponinI at admission in the intensive care unit predicts the need of dialysis in septic patients

This article by de Almeida Thiengo and colleagues was published in BMC Nephrology in November 2018.
Background:  In a previous study we showed that troponin I (TnI) > 0.42 ng/mL predicted the need of dialysis in a group of 29 septic patients admitted to the intensive care unit (ICU). We aimed to confirm such finding in a larger independent sample.
Methods:  All septic patients admitted to an ICU from March 2016 to February 2017 were included if age between 18 and 90 years, onset of sepsis  0.42 ng/mL. These patients had serum creatinine slightly higher (1.66 ± 0.34 vs. 1.32 ± 0.39 mg/dL; P <  0.0001)than those with lower TnI and similar urine output (1490 ± 682 vs. 1406 ± 631 mL;P = 0.44). At the end of the follow-up period, 70.0% of the patients with lower TnI were alive in comparison with 38.6% of those with higher TnI (p = 0.0014).After 30 days, 69.3 and 2.9% of the patients with lower and higher TnI levels remained free of dialysis, respectively (p  0.42 ng/mL persisted as a strong predictor of dialysis need (hazard ratio 3.48 [95%CI 1.69-7.18]).
Conclusions:  TnI levels at ICU admission are a strong independent predictor of dialysis need in sepsis.

The Impact of Social Support Networks on Family Resilience in an Australian Intensive Care Unit: A Constructivist Grounded Theory.

This article by Wong and colleagues was published in the Journal of Nursing Scholarship during November 2018.
Purpose:  This article discusses the findings of a grounded theory of family resilience in an Australian intensive care unit (ICU) with a specific focus on families’experiences of their interactions with other members within their own family,and the families of other patients in the ICU.
Design:  A constructivist grounded theory methodology was adopted. Data were collected using in-depth interviews with 25 family members of 21 critically ill patients admitted to a tertiary-level ICU in Australia.
Findings:  The core category regaining control represents the families’ journey toward resilience when in ICU. The major categories represent facilitators for, and barriers to,regaining control. One of the main facilitators is drawing strength, and it explains the manner with which families receive social support from their own and other family members to help them cope.
Conclusions:  This study offers a framework to improve patient- and family-centered care in the ICU by facilitating families’ ability to manage their situation more effectively.Social support offered by family members facilitates the families’ ability to regain control. An ICU family resilience theoretical framework, situated within the context of the Australian healthcare system, adds to what is currently known about the families’ experiences in the ICU.
Clinical Relevance: The relationships that develop between families in the ICU may provide a source of social support; however, not all families welcome interactions with other ICU families, and it may cause further emotional distress. Further research is warranted to determine whether families suffer a secondary stress reaction from incidental interactions with other patients’ families in the ICU.Furthermore, when family members pull together and offer social support to each other, they are better able to regain control. This process contributes to an ICU family resilience framework.

Effects of a Multimodal Program Including Simulation on Job Strain Among Nurses Working in Intensive Care Units: A Randomized Clinical Trial

This article by El Khamali and others was published inJAMA during November 2018.
Importance:  Nurses working in an intensive care unit (ICU) are exposed to occupational stressors that can increase the risk of stress reactions, long-term absenteeism, and turnover.
Objective:  To evaluate the effects of a program including simulation in reducing work-related stress and work-related outcomes among ICU nurses.
Design, Setting, and Participants:  Multi-center randomized clinical trial performed at 8 adult ICUs in France from February 8, 2016, through April 29,2017. A total of 198 ICU nurses were included and followed up for 1 year until April 30, 2018.
Interventions:  The ICU nurses who had at least 6 months of ICU experience were randomized to the intervention group (n = 101) or to the control group (n = 97). The nurses randomized to the intervention group received a 5-day course involving a nursing theory recap and situational role-play using simulated scenarios (based on technical dexterity, clinical approach, decision making, aptitude to teamwork, and task prioritization),which were followed by debriefing sessions on attitude and discussion of practices.
Main Outcomes and Measures:  The primary outcome was the prevalence of job strain assessed by combining a psychological demand score greater than 21(score range, 9 [best] to 36 [worst]) with a decision latitude score less than 72 (score range, 24 [worst] to 96 [best]) using the Job Content Questionnaire and evaluated at 6 months. There were 7 secondary outcomes including absenteeism and turnover.
Results:  Among 198 ICU nurses who were randomized (95 aged ≤30 years [48%] and 115 women [58%]),182 (92%) completed the trial for the primary outcome. The trial was stopped for efficacy at the scheduled interim analysis after enrollment of 198 participants. The prevalence of job strain at 6 months was lower in the intervention group than in the control group (13% vs 67%, respectively;between-group difference, 54% [95% CI, 40%-64%]; P < .001). Absenteeism during the 6-month follow-up period was 1% in the intervention group compared with 8% in the control group (between-group difference, 7% [95% CI, 1%-15%];P = .03). Four nurses (4%) from the intervention group left the ICU during the 6-month follow-up period compared with 12 nurses (12%) from the control group(between-group difference, 8% [95% CI, 0%-17%]; P = .04).
Conclusions and Relevance:  Among ICU nurses, an intervention that included education, role-play, and debriefing resulted in a lower prevalence of job strain at 6 months compared with nurses who did not undergo this program.Further research is needed to understand which components of the program may have contributed to this result and to evaluate whether this program is cost-effective.

Effect of a Low vs Intermediate Tidal Volume Strategy on Ventilator-Free Days in Intensive Care Unit Patients without ARDS: A Randomized Clinical Trial.

This article by the Writing Group for the PReVENT Investigators was published in JAMA in November 2018.
Importance:  It remains uncertain whether invasive ventilation should use low tidal volumes in critically ill patients without acute respiratory distress syndrome (ARDS).
Objective:  To determine whether a low tidal volume ventilation strategy is more effective than an intermediate tidal volume strategy.
Design,Setting, and Participants:  A randomized clinical trial, conducted from September 1, 2014, through August 20, 2017,including patients without ARDS expected to not be extubated within 24 hours after start of ventilation from 6 intensive care units in the Netherlands.
Interventions:  Invasive ventilation using low tidal volumes(n = 477) or intermediate tidal volumes (n = 484).
Main Outcomes and Measures:  The primary outcome was the number of ventilator-free days and alive at day 28. Secondary outcomes included length of ICU and hospital stay; ICU, hospital, and 28- and 90-day mortality; and development of ARDS, pneumonia, severe atelectasis, orpneumothorax.
Results:  In total, 961 patients (65% male), with a median age of 68 years (interquartile range [IQR], 59-76), were enrolled. Atday 28, 475 patients in the low tidal volume group had a median of 21 ventilator-free days (IQR, 0-26), and 480 patients in the intermediate tidal volume group had a median of 21 ventilator-free days (IQR, 0-26) (mean difference, -0.27 [95% CI, -1.74 to 1.19]; P = .71). There was no significant difference in ICU (median, 6 vs 6 days; 0.39 [-1.09 to 1.89]; P = .58) and hospital (median, 14 vs 15 days; -0.60 [-3.52 to 2.31]; P = .68) length of stayor 28-day (34.9% vs 32.1%; hazard ratio [HR], 1.12 [0.90 to 1.40]; P = .30) and90-day (39.1% vs 37.8%; HR, 1.07 [0.87 to 1.31]; P = .54) mortality. There was no significant difference in the percentage of patients developing the following adverse events: ARDS (3.8% vs 5.0%; risk ratio [RR], 0.86 [0.59 to 1.24];P = .38), pneumonia (4.2% vs 3.7%; RR, 1.07 [0.78 to 1.47]; P = .67), severeatelectasis (11.4% vs 11.2%; RR, 1.00 [0.81 to 1.23]; P = .94), and pneumothorax (1.8% vs 1.3%; RR, 1.16 [0.73 to 1.84]; P = .55).  
Conclusions and Relevance:  In patients in the ICU without ARDS who were expected not to be extubated within 24 hours of randomization, a low tidal volume strategy did not result in a greater number of ventilator-free days than an intermediate tidal volume strategy.
