Burnout and Turnover Intention in Critical Care Professionals During the COVID-19 Pandemic in Japan: A Cross-sectional Survey.

Rationale: The prevalence of burnout among critical care professionals during the coronavirus disease (COVID-19) pandemic varies in different countries. Objectives: To investigate the prevalence of burnout and turnover intention in Japanese critical care professionals in March 2021. Methods: This cross-sectional study used a web-based survey of Japanese critical care professionals working in 15 intensive care units in 15 prefectures. Burnout was measured using the Mini Z 2.0 Survey. Intention to leave (turnover intention) was assessed by survey. Resilience was measured using the Brief Resilience Scale (Japanese version). Demographics and personal and workplace characteristics were also collected. Results: Of 1,205 critical care professionals approached, 936 (77.6%) completed the survey. Among these, 24.3%, 20.6%, and 14.2% reported symptoms of burnout, depression, and anxiety, respectively. A total of 157 respondents (16.8%) reported turnover intention. On multivariate analysis, higher resilience scores (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.84-0.95; and OR, 0.94; 95% CI, 0.91-0.96) and perceived support from the hospital (OR, 0.64; 95% CI, 0.44-0.93; and OR, 0.54; 95% CI, 0.40-0.73) were associated with a lower odds of burnout and turnover intention, respectively. Conclusions: Approximately 24% and 17% of the Japanese critical care professionals surveyed had symptoms of burnout and turnover intention from critical care, respectively, during the COVID-19 pandemic. Such professionals require organizational support to cultivate both individual and organizational resilience to reduce burnout and turnover intention.

Association between ICU admission during off-hours and in-hospital mortality: a multicenter registry in Japan.

BACKGROUND: The effect of ICU admission time on patient outcomes has been shown to be controversial in several studies from a number of countries. The imbalance between ICU staffing and medical resources during off-hours possibly influences the outcome for critically ill or injured patients. Here, we aimed to evaluate the association between ICU admission during off-hours and in-hospital mortality in Japan. METHODS: This study was an observational study using a multicenter registry (Japanese Intensive care PAtient Database). From the registry, we enrolled adult patients admitted to ICUs from April 2015 to March 2019. Patients with elective surgery, readmission to ICUs, or ICU admissions only for medical procedures were excluded. We compared in-hospital mortalities between ICU patients admitted during off-hours and office-hours, using a multilevel logistic regression model which allows for the random effect of each hospital. RESULTS: A total of 28,200 patients were enrolled with a median age of 71 years (interquartile range [IQR], 59 to 80). The median APACHE II score was 18 (IQR, 13 to 24) with no significant difference between patients admitted during off-hours and those admitted during office-hours. The in-hospital mortality was 3399/20,403 (16.7%) when admitted during off-hours and 1604/7797 (20.6%) when admitted during office-hours. Thus, off-hours ICU admission was associated with lower in-hospital mortality (adjusted odds ratio 0.91, [95% confidence interval, 0.84-0.99]). CONCLUSIONS: ICU admissions during off-hours were associated with lower in-hospital mortality in Japan. These results were against our expectations and raised some concerns for a possible imbalance between ICU staffing and workload during office-hours. Further studies with a sufficient dataset required for comparing with other countries are warranted in the future.

Patient-centered outcomes at hospital discharge in mechanically ventilated COVID-19 patients in Kobe, Japan: A single-center retrospective cohort study.

BACKGROUND: Apart from saving the lives of coronavirus disease (COVID-19) patients on mechanical ventilation (MV), recovery from the sequelae of prolonged MV (PMV) is an emerging issue.c METHODS: We conducted a retrospective study among consecutive adult COVID-19 patients admitted to an intensive care unit (ICU) in Kobe, Japan, between March 3, 2020, and January 31, 2021, and received invasive MV. Clinical outcomes included in-hospital mortality and recovery from COVID-19 in survivors regarding organ dysfunction, respiratory symptoms, and functional status at discharge. We compared survivors' outcomes with MV durations of >14 days and ≤14 days. RESULTS: We included 85 patients with a median age of 69 years (interquartile range, 64-75 years); 76 (89%) patients had at least 1 comorbidity, 72 (85%) were non-frail, and 79 (93%) were functionally independent before COVID-19 infection. Eighteen patients (21%) died during hospitalization. At discharge, 59/67 survivors (88%) no longer required respiratory support, 50 (75%) complained of dyspnea, and 40 (60%) were functionally independent. Of the survivors, 23 patients receiving MV for >14 days had a worse recovery from COVID-19 at discharge compared with those on MV for ≤14 days, as observed using the Barthel index (median: 35 [5-65] vs. 100 [85-100]), ICU mobility scale (8 [5-9] vs. 10 [10-10]), and functional oral intake scale (3 [1-7] vs. 7 [7-7]) (P < 0.0001). CONCLUSION: Although four-fifths of the patients survived and >50% of survivors demonstrated clinically important recovery in organ function and functional status during hospitalization, PMV was related to poor recovery from COVID-19 at discharge.

Incidence of Adverse Events Associated With the In-Hospital Transport of Critically Ill Patients.

IMPORTANCE: Despite various reports on the incidence of adverse events related to the in-hospital transport of critically ill patients, there is little verification of the correlation between the occurrence of adverse events and the use of checklists. The risk factors for the occurrence of adverse events during transport based on the use of checklists have not been well studied. Understanding them can contribute to making patient transport safer. OBJECTIVES: We aimed to investigate the frequency of adverse events and risk factors related to the in-hospital transport of critically ill patients in a hospital that uses a checklist for transporting patients. DESIGN SETTING AND PARTICIPANTS: This single-center, prospective, observational study was conducted between February 1, 2020, and July 31, 2020, at Kobe City Medical Center General Hospital, Japan. Patients greater than or equal to 18 years old who were admitted to the ICU and were transported for examination or procedures were included. MAIN OUTCOMES AND MEASURES: The transport member recorded patient information and any adverse events that occurred and filled out an information collection form. We then applied multivariate analysis to identify risk factors. RESULTS: A total of 117 transports for 117 patients were evaluated in this study. Twenty-two adverse events occurred in 20 transports (17.1%). There were nine transports (7.7%) in which the patients required treatment, all of which were related to patient instability. Multivariate logistic regression analysis showed that the use of sedative drugs was related to adverse events (odds ratio, 2.9; 95% CI, 1.0-8.5; p = 0.04). We were not able to show a relationship of either the severity of the illness or body mass index with the occurrence of adverse events. CONCLUSIONS AND RELEVANCE: This study revealed that the frequency of adverse events related to the in-hospital transportation of critically ill patients based on the use of a checklist was 17.1% and that the use of sedatives was associated with adverse events.

Clinical characteristics and outcomes of critically ill patients with COVID-19 in Kobe, Japan: a single-center, retrospective, observational study.

PURPOSE: Coronavirus disease 2019 (COVID-19) has placed a great burden on critical care services worldwide. Data regarding critically ill COVID-19 patients and their demand of critical care services outside of initial COVID-19 epicenters are lacking. This study described clinical characteristics and outcomes of critically ill COVID-19 patients and the capacity of a COVID-19-dedicated intensive care unit (ICU) in Kobe, Japan. METHODS: This retrospective observational study included critically ill COVID-19 patients admitted to a 14-bed COVID-19-dedicated ICU in Kobe between March 3, 2020 and June 21, 2020. Clinical and daily ICU occupancy data were obtained from electrical medical records. The last follow-up day was June 28, 2020. RESULTS: Of 32 patients included, the median hospital follow-up period was 27 (interquartile range 19-50) days. The median age was 68 (57-76) years; 23 (72%) were men and 25 (78%) had at least one comorbidity. Nineteen (59%) patients received invasive mechanical ventilation for a median duration of 14 (8-27) days. Until all patients were discharged from the ICU on June 5, 2020, the median daily ICU occupancy was 50% (36-71%). As of June 28, 2020, six (19%) died during hospitalization. Of 26 (81%) survivors, 23 (72%) were discharged from the hospital and three (9%) remained in the hospital. CONCLUSION: During the first months of the outbreak in Kobe, most critically ill patients were men aged ≥ 60 years with at least one comorbidity and on mechanical ventilation; the ICU capacity was not strained, and the case-fatality rate was 19%.

A study of the effect of introduction of JTAS in the emergency room.

Aim: The purpose of this study was to better understand the effects of introducing the Japan Triage and Acuity Scale (JTAS) in the emergency room for walk-in patients. Methods: A simple triage was used in Term A (from April 2006 to December 2010, 4 years and 9 months) and the JTAS was introduced in Term B (from January 2011 to September 2015, 4 years and 9 months). The number of patients who had a sudden turn for the worse after arrival in the emergency room and the time between attendance and emergency catheterization (TBAEC) due to acute coronary syndrome were reviewed. Results: There were 653 patients in Term A and 626 patients in Term B who were finally diagnosed as having serious causes. There was no significant difference in the frequency of a sudden turn for the worse between the two terms. There were 182 patients in Term A and 167 patients in Term B who underwent emergency catheterization due to acute coronary syndrome. When ST elevation was recognized in the first electrocardiogram, the median time between attendance and medical attention during Term B improved significantly, by 4.5 min. However, there was no significant difference in medians for TBAEC. When ST elevation was not recognized, there was no significant difference between the two terms, neither in terms of median time between attendance and medical attention, nor TBAEC. Conclusion: The data suggests that the effects of introducing the JTAS in the emergency room were restrictive in these two aspects.

Diagnosis of Ingested Foreign Body in the Stomach by Point-of-Care Ultrasound in the Upright and Slightly Forward Tilting Position (Bowing Position).

We report a case involving accidental ingestion of a marble that was detected by point-of-care ultrasonography of the abdomen with the patient in the upright and slightly forward tilting position, which we term the "bowing position." Using this position for abdominal ultrasonography may be more useful than the usual supine position for such patients.

Relationship between metformin use, vitamin B12 deficiency, hyperhomocysteinemia and vascular complications in patients with type 2 diabetes.

Aim of the study was to clarify the relationship between metformin-induced vitamin B12 (B12) deficiency, hyperhomocysteinemia and vascular complications in patients with type 2 diabetes. Serum B12 concentrations, homocysteine plasma levels, the presence of retinopathy and history of macroangiopathy (stroke or coronary heart disease) were analyzed in patients without renal dysfunction (serum creatinine<115 µmol/L). Firstly, B12 status was analyzed in 62 consecutive metformin-treated patients. Secondly, the relationship between B12, homocysteine and vascular complications was analyzed in 46 metformin-treated and 38 age- and sex-matched non-metformin-treated patients. Among the 62 consecutive metformin-treated patients, B12 was deficient (<150 pmol/L) in 8 (13%) and borderline-deficient (150-220 pmol/L) in 18 (29%): the larger the metformin dosage, the lower the B12 (P=0.02, Spearman's ρ=-0.30). There were independent correlations between metformin use and B12 lowering (P=0.02, r = -0.25), and B12 lowering and elevation of homocysteine (P<0.01, r=-0.34). Elevation of homocysteine was a risk for retinopathy (P=0.02, OR 1.26, 95%CI 1.04-1.52). There was no significant relation between homocysteine and macroangiopathy. Correlation between B12 and homocysteine was stronger in metformin-treated (P<0.01, r=-0.48) than non-metformin-treated (P=0.04, r=-0.38) patients. In ten B12 deficient patients, B12 supplementation (1,500 µg/day) for 2.2±1.0 months with continued use of metformin raised B12 levels: 152±42 and 299±97 pmol/L before and after treatment, respectively (P<0.01). Metformin-induced B12 lowering in diabetes was associated with elevation of homocysteine, and hyperhomocysteinemia was independently related to retinopathy. Metformin-induced B12 deficiency was correctable with B12 supplementation.
