Effects of social support on mental health for critical care nurses during the coronavirus disease 2019 (COVID-19) pandemic in Japan: A web-based cross-sectional study
AimThe aim of this study was to examine whether high social support has a protective effect on mental health for critical care nurses during the coronavirus disease 2019 (COVID-19) pandemic.MethodsThis cross-sectional anonymous web-based survey was conducted from November 5 to December 5, 2020, in Japan and included critical care nurses. The invitation was distributed via mailing lists.ResultsOf the 334 responses that were obtained, 64.4% were from female respondents, and their mean age was 37.4. Of the total, 269 (80.5%) were taking care of COVID-19 patients at the time the study was conducted. Participants with post-traumatic stress disorder (PTSD) symptoms were found to be older (P < 0.05), and those with an education level of a 4-year college degree or higher had fewer PTSD symptoms (P < 0.05). Those experiencing anxiety and depressive symptoms had lower social support scores. Having a 4-year college degree and higher (odds ratio [OR] 0.622, 95% confidence interval [CI] 0.39–0.99) was significantly associated with a lower probability of PTSD. Social support scores and the female sex were not associated with PTSD. Regarding anxiety symptoms, being female and having lower social support were independently associated with a higher probability. Regarding depression symptoms, lower social support was independently associated with a higher probability (OR 0.953, 95% CI 0.93–0.97).ConclusionIt was found that social support was not associated with PTSD; however, it was associated with depression and anxiety symptoms for intensive care nurses during the COVID-19 pandemic
Influence of mutual support and a culture of blame among staff in acute care units on the frequency of physical restraint use in patients undergoing mechanical ventilation
AimReducing the use of physical restraint in intensive care units is challenging, and little is known about the influence of culture on physical restraint use in this setting. The present study aims to verify the hypothesis that mutual support and a culture of blame among staff are associated with higher physical restraint use for mechanically ventilated patients.MethodsWe undertook a survey of nurses in intensive care units caring for mechanically ventilated patients in acute care units. The perceived frequency of physical restraint, mutual support, and culture of blame were measured. We predefined a high frequency physical restraint use group and compared the institutional characteristics, human resources, mutual support, and culture of blame between this group and the others (the control).ResultsThree hundred and thirty-three responses were analyzed. The mean number of beds per nurse was not significantly different between the groups; the mean and percentage of positive responses about mutual support and a culture of blame were significantly lower in the high frequency physical restraint use group. After adjusting variables in a multivariable regression analysis, a less positive response about the culture of blame was the only independent factor to predict high frequency physical restraint use.ConclusionThe study suggests that changing the culture of blame, rather than increasing the number of nurses, is important for reducing physical restraint use
Association between intensive care unit delirium and delusional memory after critical care in mechanically ventilated patients
AimTo determine the relationship between the delirium of patients with mechanical ventilation during intensive care unit (ICU) stay and delusional memory after ICU discharge.DesignProspective cohort study.MethodsDelirium in adult patients who received mechanical ventilation for more than 24 hr was assessed twice daily using the Confusion Assessment Method for the ICU. Delusional memories were evaluated using the ICU Memory Tool 5–10 days after ICU discharge. The associations between the presence of delirium during the ICU stay and delusional memories were evaluated.ResultsOf 60 enrolled patients, 62% had delirium during their ICU stay, and 68% experienced delusional memories 5–10 days after discharge. Delirium during ICU stay was an independent factor to experience delusional memories following discharge. Preventing delirium during ICU stay might reduce delusional memory. We recommend that patients with delirium during their ICU stay should be carefully followed up after discharge from the ICU
Effects of Closed Vs. Open Repeated Endotracheal Suctioning During Mechanical Ventilation on the Pulmonary and Circulatory Levels of Endothelin-1 in Lavage-Induced Rabbit ARDS Model
Background: A growing body of evidence demonstrates discretely the difference of open endotracheal suctioning (OES) and closed endotracheal suctioning (CES) on the respiratory and hemodynamic parameters in acute respiratory distress syndrome (ARDS). Endothelin-1 (ET-1), a mediator of vascular inflammation, cell proliferation, and fibrosis in addition to being a potent vasoconstrictor has been potentially implicated in the pathogenesis of ARDS. Here, we investigated the effects of repeated OES vs. CES during mechanical ventilation on circulatory and pulmonary levels of ET-1 in ARDS. Methods: Briefly, 22 Japanese White Rabbits were intubated with a 3.5-mm endotracheal tube. Normal saline was instilled into lung and washed mildly. After instillation, rabbits were ventilated at definite setting; OES and CES duration was for 6 hours and performed every 30 minutes from protocol start. Results: At circulatory level, either OES or CES did not alter plasma ET-1 level compared to the ET-1 level in ARDS before the initiation of endotracheal suctioning (OES 4.7 ± 1.3 pg/ml vs. CES 4.8 ± 1.5 pg/ml, p=0.839). In contrast, pulmonary ET-1 level was significantly higher in CES group compared to OES group after 6 hours of repeated suctioning in ARDS (OES 26.9 ± 2.2 pg/mg vs. CES 29.9 ± 3.3 pg/mg, p=0.018). This change in pulmonary ET-1 level could maintain a parallel relation with PaO2 level. Conclusion: At this moment, we cannot clarify the mechanism and effects of the observed change in ET-1 in a rabbit model of ARDS as well as its clinical impact.Research Articl
PERSonality, Ehical, and PROfessional quality of life in Pediatric/Adult Intensive Nurses study: PERSEPRO PAIN study
BackgroundThe World Health Organization included burnout syndrome criteria that reduce both professional quality of life and work satisfaction in its 11th Revision of the International Classification of Diseases in 2019 while nursing bodies have issued action calls to prevent burnout syndrome. Despite this, the effect of social factors, personality traits and cross-interaction on professional quality of life is still unclear.AimTo reveal the association between ethical climate, personal trait and professional quality of life.MethodAn online survey of registered nurses working in adult, pediatric or both ICUs. We used the ten-item personality measure based on The Big Five theory and Type-D personality Scale-14 then measured the ethical climate with the Hospital Ethical Climate Survey and the professional domains of burnout syndrome, secondary traumatic stress and compassion satisfaction by the Professional Quality of Life Scale Version 5 simultaneously. Multivariate analysis confirmed the triangular association of hospital ethical climate, personality traits and professional quality of life.ResultWe enrolled 310 participants from September 2019 to February 2020. Mean age was 33.1 years (± 5.9) and about 70% were female. In the multivariate analysis, neuroticism (p = 0.03, p = 0.01) and Type D personality (both of p<0.01) were associated with burnout syndrome and secondary traumatic stress while agreeableness (p<0.01) was associated with secondary traumatic stress. Conversely, extraversion (p = 0.01), agreeableness (p<0.01) and openness (p<0.01) were associated with compassion satisfaction. We also observed interactions between hospital ethical climate and conscientiousness (p = 0.01) for burnout syndrome and secondary traumatic stress. Neuroticism was related to (p<0.01) BOS and compassion satisfaction while Type D personality (p<0.01) correlated with burnout syndrome and secondary traumatic stress.ConclusionHospital ethical climate strongly affects professional quality of life in nurses with specific personality traits. Therefore, it is important to maintain an ethical hospital climate, considering individual personalities to prevent burnout syndrome
Down Syndrome Reduces the Sedative Effect of Midazolam in Pediatric Cardiovascular Surgical Patients
Down syndrome (DS) is frequently comorbid with congenital heart disease and has recently been shown to reduce the sedative effect of benzodiazepine (BDZ)-class anesthesia but this effect in a clinical setting has not been studied. Therefore, this study compared midazolam sedation after heart surgery in DS and normal children. We retrospectively reviewed patient records in our pediatric intensive care unit (PICU) of pediatric cardiovascular operations between March 2015 and March 2018. We selected five days of continuous post-operative data just after termination of muscle relaxants. Midazolam sedation was estimated by Bayesian inference for generalized linear mixed models. We enrolled 104 patients (average age 26 weeks) of which 16 (15%) had DS. DS patients had a high probability of receiving a higher midazolam dosage and dexmedetomidine dosage over the study period (probability = 0.99, probability = 0.97) while depth of sedation was not different in DS patients (probability = 0.35). Multi regression modeling included severity scores and demographic data showed DS decreases midazolam sedation compared with controls (posterior OR = 1.32, 95% CrI = 1.01–1.75). In conclusion, midazolam dosages should be carefully adjusted as DS significantly decreases midazolam sedative effect in pediatric heart surgery patients
Translation, reliability, and validity of Japanese version of the Respiratory Distress Observation Scale
Dyspnea is a common, distressing symptom of cardiopulmonary and neuromuscular diseases and is defined as “a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity.” However, Japanese intensive care units (ICUs) do not routinely screen for dyspnea, as no validated Japanese version of the Respiratory Distress Observation Scale (RDOS) is available. Therefore, we aimed to translate the English version of this questionnaire into Japanese and assess its validity and reliability. To translate the RDOS, we conducted a prospective observational study in a 12-bed ICU of a universal hospital that included 42 healthcare professionals, 10 expert panels, and 128 ventilated patients. The English version was translated into Japanese, and several cross-sectional web-based questionnaires were administered to the healthcare professionals. After completing the translation process, a validity and reliability evaluation was performed in the ventilated patients. Inter-rater reliability was evaluated using Cohen’s weighted kappa coefficient. Criterion validity was ascertained based on the correlation between RDOS and the dyspnea visual analog scale. The area under the receiver operating characteristic curve analysis was used to evaluate the ability of the RDOS to identify patients with self-reported dyspnea. The average content validity index at the scale level was 0.95. Data from the 128 patients were collected and analyzed. Cohen’s weighted kappa coefficient and the correlation coefficient between the two scales were 0.76 and 0.443 (95% confidence intervals 0.70–0.82 and 0.23–0.62), respectively. For predicting self-reported dyspnea, the area under the receiver operating characteristic curve was 0.81 (95% confidence interval 0.67–0.97). The optimal cutoff used was 1, with a sensitivity and specificity of 0.89 and 0.61, respectively. Our findings indicated that the Japanese version of the RDOS is acceptable for face validity, understandability, criterion validity, and inter-rater reliability in lightly sedated mechanically ventilated patients, indicating its clinical utility
Assessment of circulatory and pulmonary endothelin-1 levels in a lavage-induced surfactant-depleted lung injury rabbit model with repeated open endotracheal suctioning and hyperinflation
Aims:Endothelin-1 (ET-1) is a mediator of various physiological and pathological processes, including vascular inflammation, cell proliferation and vasoconstriction. Attenuation of ET action using ET-1 antagonists reduces pulmonary vascular leakage and inflammation in several models of lung injuries and experimental acute respiratory distress syndrome (ARDS). Based on these earlier reports, the current study investigates the patterns of ET-1 levels in circulation and pulmonary tissues in an experimental model of lavage-induced surfactant-depleted lung injury. Additionally, we also test the effects of open endotracheal suctioning (OES) and hyperinflation (HI) as recruitment maneuver following OES on ET-1 levels.Main methods:Briefly, 24 Japanese white rabbits were anesthetized and intubated. Normal saline was instilled into the lung and washed mildly. After instillation, rabbits were ventilated at definite settings at a total duration of 3 hours. OES and HI were performed every 15 minutes from the beginning of the protocol.Key findings:Here, we show that both circulatory and pulmonary ET-1 levels increased in models with lung injury induced by saline lavage compared to healthy control group. No further aggravation in expression of pulmonary ET-1 was seen after OES and HI, although OES and HI worsened arterial hypoxygenation and severity of lung injury. In contrast, circulatory ET-1 levels significantly decreased after OES and HI but were not associated with blood pressure changes.Significance:We conclude that in a saline lavage-induced lung injury model, both circulatory and pulmonary ET-1 levels increased. Further, OES and HI exerted differential effects on ET-1 expression at both circulatory and pulmonary levels
