RESUMEN
BACKGROUND: Burnout is common and can lead to worse outcomes for both healthcare workers and patients. Our study purpose was to assess the structural relationship among factors that protect against or worsen burnout. DATA SOURCES AND STUDY SETTING: We surveyed healthcare professionals in 15 different Japanese intensive care units during the 3rd wave of the COVID-19 pandemic (March 2021). Surveys assessed burnout (Mini Z 2.0), resilience (Brief Resilience Scale), depressive (PHQ-9) and anxiety (GAD-7) symptoms, job and work environment characteristics, and personal experience with COVID. We explored survey domains with principal component factor analysis and modeled our results using structural equation modeling. PRINCIPAL FINDINGS: Among 936 ICU professionals, 24.3% met criteria for burnout. Our model suggested that resilience (ß = - 0.26, 95% CI - 0.32 to - 0.20), teamwork (ß = - 0.23, 95% CI - 0.30 to - 0.16), and feeling safe (ß = - 0.11, 95% CI - 0.18 to - 0.04) reduced burnout. Depression (ß = - 0.32, 95% CI - 0.41 to - 0.23) and anxiety (ß = - 0.20, 95% CI - 0.29 to - 0.10) both decreased resilience as did COVID fear (ß = 0.08, 95% CI - 0.14 to - 0.02). In addition to directly reducing resilience, anxiety also indirectly reduced resilience by increasing COVID fear (0.23, 95% CI 0.17 to 0.23), which decreased resilience (ß - 0.08, 95% CI - 0.14 to - 0.02). CONCLUSIONS: Burnout is common among Japanese ICU professionals. Resilience, teamwork, and safety are all correlated with reduced burnout. Those who had depression or anxiety or COVID fear had higher degrees of burnout, an effect that appears to be mediated by reduced resilience. These are potential targets for interventions to reduce burnout.

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.

INTRODUCTION: Psychological disorders, such as depression, are markedly prevalent in patients with airway diseases. In this study, we assessed the effect of treatment with dupilumab, an IL-4 receptor α chain antibody, on depressive symptoms in a cohort of patients with asthma with eosinophilic chronic rhinosinusitis (ECRS). METHODS: The study participants, diagnosed with asthma and ECRS, were assessed for symptoms and quality of life (QOL) scores for asthma and ECRS and medications. The Patient Health Questionnaire-9 (PHQ-9) scores were used to evaluate the depressive state. The depressive symptoms were compared with asthma and ECRS symptoms both at the time of initiation and after 4 months of dupilumab treatment. RESULTS: Ultimately, 31 patients were included in the study. Most patients demonstrated a depressive state that was correlated with the nasal symptom score. In the evaluation 4 months after dupilumab treatment, the PHQ-9 score was significantly reduced, and the decrease was remarkable in patients whose nasal symptom score was reduced by 50% or more. Additionally, the PHQ-9 scores in patients with improved nasal and asthma symptoms were significantly reduced. DISCUSSION/CONCLUSION: Dupilumab may improve QOL in patients with bronchial asthma with ECRS by reducing depressive symptoms through the improvement of clinical symptoms.

The 7-item Generalized Anxiety Disorder Scale (GAD-7) is commonly used to monitor anxiety symptoms. However, its factor structure has been inconsistent among competing models: unidimensional, two-dimensional, or higher order models. Additionally, it is unknown whether the scale has measurement invariance between populations with and without self-reported psychiatric diagnostic status. Participants were Japanese adults with self-reported anxiety disorder (AD; n = 479), self-reported AD and major depressive disorder (MDD; n = 314), or without self-reported psychiatric diagnostic status (self-reported non-MDD/AD; n = 654), who completed this questionnaire on the Internet. Confirmatory factor analyses showed the higher order model had similar fit indices to the unidimensional and two-dimensional factor models. For the higher order model of GAD-7, metric invariance was supported between the self-reported non-MDD/AD and self-reported AD status groups, and scalar invariance was supported between the self-reported AD status and self-reported AD with MDD status groups. Moreover, convergent and discriminant validity were consistent with previous findings in Western cultures. These results suggest that factor loadings are equivalent and the construct has the same meaning between the self-reported non-MDD/AD and self-reported AD status groups, and the total or sub-scale scores were comparable between self-reported AD status and self-reported AD with MDD status groups. The major limitation of this study is that the participants' diagnoses were self-reported, not confirmed by clinical structured interview. Further studies that incorporate clinical structured interviews are needed.
RESUMEN
The Patient Health Questionnaire-9 (PHQ-9) is commonly used to screen for depressive disorder and for monitoring depressive symptoms. However, there are mixed findings regarding its factor structure (i.e., whether it has a unidimensional, two-dimensional, or bi-factor structure). Furthermore, its measurement invariance between non-clinical and clinical populations and that between patients with major depressive disorder (MDD) and MDD with comorbid anxiety disorder (AD) is unknown. Japanese adults with MDD (n = 406), MDD with AD (n = 636), and no psychiatric disorders (non-clinical population; n = 1,163) answered this questionnaire on the Internet. Confirmatory factor analyses showed that the bi-factor model had a better fit than the unidimensional and two-dimensional factor models did. The results of a multi-group confirmatory factor analysis indicated scalar invariance between the non-clinical and only MDD groups, and that between the only MDD and MDD with AD groups. In conclusion, the bi-factor model with two specific factors was supported among the non-clinical, only MDD, and MDD with AD groups. The scalar measurement invariance model was supported between the groups, which indicated the total or sub-scale scores were comparable between groups.

OBJECTIVE: To assess the performance of the Japanese version of the Patient Health Questionnaire-9 (J-PHQ-9) for depression in primary care. METHODS: Participants in both phases completed the J-PHQ-9, while patients in the second phase also completed the SF-8 (the short form for the health-related QOL scale SF-36). Subjects (nâ¯=â¯284; maleâ¯=â¯107, femaleâ¯=â¯177) had to return the questionnaires to their health care professional within 48 hours and undergo a diagnostic evaluation interview based on the Japanese version of M.I.N.I-Plus. RESULTS: 93 patients were diagnosed as having major depressive disorder (MDD). In the J-PHQ-9, the optimal cutpoint ≥â¯10 had sensitivity of 90.5% and specificity of 76.6%. As for the categorical algorithms, the sensitivity was 80.6%; specificity was 89.5%, and a positive likelihood ratio of 7.7. The Stratum-specific likelihood ratios (SSLRs) of the J-PHQ-9 scores of 0-9, 10-14, 15-19, and 20-27 for major depression were 0.10 (95% CI: 0.05-0.20), 1.67 (95% CI: 1.02-2.76), 5.41 (95% CI: 2.87-10.22), and 11.98 (95% CI: 5.39-26.63), respectively. The relationship between the severity of J-PHQ-9 and the MCS of SF-8 was significant (χâ¯2â¯ï¼â¯85.72, dfâ¯=â¯4, Pâ¯≤â¯0.0001). CONCLUSIONS: This study has validated the J-PHQ-9 as a useful tool for the assessment of MDD in primary care in Japan.

Objective Whether or not depression affects the control or severity of asthma is unclear. We performed a cluster analysis of asthma patients with depressive symptoms to clarify their characteristics. Methods Multiple medical institutions in Niigata Prefecture, Japan, were surveyed in 2014. We recorded the age, disease duration, body mass index (BMI), medications, and surveyed asthma control status and severity, as well as depressive symptoms and adherence to treatment using questionnaires. A hierarchical cluster analysis was performed on the group of patients assessed as having depression. Results Of 2,273 patients, 128 were assessed as being positive for depressive symptoms [DS(+)]. Thirty-three were excluded because of missing data, and the remaining 95 DS[+] patients were classified into 3 clusters (A, B, and C). The patients in cluster A (n=19) were elderly, had severe, poorly controlled asthma, and demonstrated possible adherence barriers; those in cluster B (n=26) were elderly with a low BMI and had no significant adherence barriers but had severe, poorly controlled asthma; and those in cluster C (n=50) were younger, with a high BMI, no significant adherence barriers, well-controlled asthma, and few were severely affected. The scores for depressive symptoms were not significantly different between clusters. Conclusion About half of the patients in the DS[+] group had severe, poorly controlled asthma, and these clusters were able to be distinguished by their Adherence Starts with Knowledge (ASK)-12 score, which reflects adherence barriers. The control status and severity of asthma may also be related to the age, disease duration, and BMI in the DS[+] group.

BACKGROUND: Depression has been linked to poorer asthma control in asthmatic patients. Although the Japanese version of the Asthma Control Test (ACT-J) is frequently used as a simple, practical evaluation tool in clinical care settings in Japan, knowledge regarding its efficacy for assessing asthma control in asthmatic patients with depression is limited. Thus, we retrospectively investigated cut-off values of the ACT-J for well-controlled asthma, and explored depression's influence on the test with a questionnaire survey. METHODS: Data were analyzed on 1,962 adult asthmatic patients who had completed both the ACT-J and the Japanese version of the Patient Health Questionnaire-9 (J-PHQ-9) in 2008 questionnaire survey conducted by the Niigata Asthma Treatment Study Group. Patients were classified into low (LD: J-PHQ-9 score of 0-4) or high depression (HD: J-PHQ-9 score of 5-27) groups. In both groups, the efficacy of the ACT-J was confirmed. We then compared the optimal cut-off points for uncontrolled asthma in both groups by performing a receiver operating characteristic (ROC) analysis, using the original classification referred to the GINA classification as the "true" classification. RESULTS: Cronbach's alpha in the LD and HD group was 0.808 and 0.740 respectively. In both groups, the sub-group with existence of work absenteeism or frequent attacks during the previous 12 months scored lower on the ACT-J. The area under the curve and optimal cut-off point for patients with LD and HD were 0.821 and 0.846, and 23 and 20 respectively. CONCLUSIONS: The efficacy of the ACT-J was confirmed in depressive patients with asthma. Because asthma control as evaluated with the ACT-J can be worse than actual control under depressive states, physicians should also pay attention to a patient's depressive state at evaluation. Further investigations focus on the association between the ACT-J and depression are required.

OBJECTIVE: Two depression screening tools, Patient Health Questionnaire (PHQ)-9 and PHQ-2, have not had their validity examined in general internal medicine settings in Japan. We examined the validity of these screening tools. METHODS: A total of 598 outpatients of an internal medicine clinic in a rural general hospital were enrolled consecutively and stratified by PHQ-9 score. Seventy-five patients randomly selected and 29 patients whose results from the PHQ-9 were considered to be positive for depressive disorder were then interviewed with a semistructured interview, the Mini International Neuropsychiatric Interview. We calculated diagnostic accuracy of the PHQ-9 and PHQ-2 to detect major depression and that of the suicidality item of the PHQ-9 to detect suicidality using sampling weights with multiple imputations. RESULTS: Sensitivity and specificity for depression were 0.86 and 0.85, respectively, for the PHQ-9 with cutoff points of 4/5, and 0.77 and 0.95, respectively, for the PHQ-2 with cutoff points of 2/3. Sensitivity and specificity of the suicidality item of the PHQ-9 were 0.70 and 0.97, respectively. CONCLUSION: In internal medicine clinics in Japanese rural hospitals, the PHQ-2 with an optimal cutoff point for each setting plus the suicidality item of the PHQ-9 can be recommended to detect depression without missing suicidality.

OBJECTIVE: In Europe and the US, primary care has been anticipated in identifying untreated depression. Findings show a high prevalence of depression in such settings. However, the prevalence of depression in an internal medicine clinic in a rural area of Japan, which has a role in primary care, is unclear. METHOD: The prevalence of depression and comorbid psychiatric disorders among outpatients of an internal medicine clinic in a rural general hospital was measured by a structured interview using the Mini International Neuropsychiatric Interview. Outpatients were recruited consecutively and stratified by Patient Health Questionnaire-9 (PHQ-9) scores. Among 598 outpatients, we interviewed 75 randomly selected patients and 29 whose results of the PHQ-9 were positive. We estimated prevalence of depressive episode using age, sex, physical findings by internal medical doctors and PHQ-9 scores as covariates. RESULTS: The estimated prevalence of major and minor depressive episodes were 7.4% [95% confidence interval (CI): 3.4%-11.4%] and 6.8% (95% CI: 2.6%-10.9%), respectively. Among major depressed patients, 71.4% had current suicidal ideation. CONCLUSION: Given the high rate of depression and suicidality, identification of depression and collaboration between internal medical doctors in a rural area of Japan and mental health professionals are needed.

BACKGROUND: Previous studies show that depression plays an important role in asthma. However, the association between asthma control and severity, and depression is inconclusive. METHODS: To investigate the association between asthma control and severity, and depression, we assessed differences in asthma control and asthma severity between groups with various grades of depressive state as defined by the PHQ-9 score using data from the Japanese version of Patient Health Questionnaire-9 (J-PHQ-9) and a questionnaire survey including the Asthma Control Test (ACT). RESULTS: The ACT scores in the symptom-screen positive (SP) and major/other depressive disorder (MDD/ODD) group were significantly lower than those in the symptom-screen negative (SN) and non-MDD/ODD groups, respectively. The rate of step1 and of step 3 and 4 in the SP group were significantly lower and higher than those in the SN group, respectively. When the SP group was divided into three, that is minimal, mild, and more than mild (MTM) depressive state subgroups, the ACT scores in the mild and MTM depressive state subgroups were significantly lower than those in the minimal depressive state subgroup. When the MTM subgroup was divided into moderate, moderate-severe and severe depressive state groups, however, there was no significant variation in ACT score and asthma severity among these three depressive state groups. CONCLUSIONS: This study is the first, large-scale investigation of the use of the J-PHQ-9 in asthma patients. Using the J-PHQ-9 and the questionnaire, there was a clear association between asthma control and severity, and depression. As the depression became more severe, the existence of other depression-associated factors unrelated to asthma control and severity might be assumed, although further investigation will be required.

BACKGROUND: A general internist has an important role in primary care, especially for the elderly in rural areas of Japan. Although effective intervention models for depressed patients in general practice and primary care settings have been developed in the US and UK medical systems, there is little information regarding even the recognition rate and prescription rate of psychotropic medication by general internists in Japan. The present study surveyed these data cross-sectionally in a general internal medicine outpatient clinic of a Japanese rural hospital. METHODS: Patients were consecutively recruited and evaluated for major depressive disorder or any mood disorder using the Patient Health Questionnaire (PHQ). Physicians who were blinded to the results of the PHQ were asked to diagnose whether the patients had any mental disorders, and if so, whether they had mood disorders or not. Data regarding prescription of psychotropic medicines were collected from medical records. RESULTS: Among 312 patients, 27 (8.7%) and 52 (16.7%) were identified with major depressive disorder and any mood disorder using the PHQ, respectively. Among those with major depressive disorder, 21 (77.8%) were recognized by physicians as having a mental disorder, but only three (11.1%) were diagnosed as having a mood disorder.Only two patients with major depressive disorder (7.4%) had been prescribed antidepressants. Even among those (n = 15) whom physicians diagnosed with a mood disorder irrespective of the PHQ results, only four (26.7%) were prescribed an antidepressant. CONCLUSIONS: Despite a high prevalence of depression, physicians did not often recognize depression in patients. In addition, most patients who were diagnosed by physicians as having a mood disorder were not prescribed antidepressants. Multiple barriers to providing appropriate care for depressed patients exist, such as recognizing depression, prescribing appropriate medications, and appropriately referring patients to mental health specialists.

Patients with obstructive sleep apnea syndrome (OSAS) have a morphological and functional abnormality of the upper respiratory tract, and the obesity of these patients is the main cause for OSAS. Obese patients with OSAS are closely associated with life-style related diseases and metabolic syndromes. The circulatory system is most strongly influenced by OSAS and hypertension, cerebrovascular disease and cardiovascular disease are the prime complications of OSAS. A psychosomatic approach is required for the treatment of OSAS in patients with obesity. The pathophysiology of upper airway resistance syndrome (UARS) is similar to OSAS in that there is abnormal airway resistance in the upper airway during sleep, but UARS does not meet the diagnostic criteria of OSAS. UARS should be classified as a separate syndrome or as part of the larger group of sleep-disordered breathing (SDB). Patients with UARS have a clinical condition that differs from that of patients with OSAS and resembles the condition of patients with functional somatic syndrome (FSS). We sometimes find slightly lower levels of night arterial saturation in patient with unidentified somatic symptoms. This is also found in patients with UARS. It is necessary to examine the respiratory events of patients with FSS and unidentified somatic symptoms during sleep.

To validate the Japanese version of the Patient Health Questionnaire against the Mini-International Neuropsychiatric Interview-Plus in Japan 131 patients in 4 primary care settings and 2 general hospital settings participated. These patients completed the Patient Health Questionnaire and returned it to their physician within 48 hr. Subsequently, the subjects underwent a diagnostic evaluation interview based on the Mini-International Neuropsychiatric Interview-Plus by an interviewer blind to the results of the Patient Health Questionnaire screening. The Patient Health Questionnaire diagnosis was characterized using kappa values between 0.70 and 1.0 for Somatoform Disorder, Major Depressive Disorder, Panic Disorder, Bulimia Nervosa, Alcohol Abuse/Dependence, and Premenstrual Disorder. Sensitivities, specificities, and negative predictive values were very good (between 0.84 and 1.0) for the first 4 diagnoses but not Alcohol Abuse/Dependence or Premenstrual Disorder, as were the Positive predictive values (between 0.78 and 1.0). Findings show very good concordance of the Japanese version of the Patient Health Questionnaire with the Japanese version of the Mini-International Neuropsychiatric Interview-Plus.

To assess the cultural differences in the role of somatosensory amplification in Japan and North America, we re-examined the role of psychological amplification of objective physical symptoms, as measured by the Somatosensory Amplification Scale (SSAS), in 82 Japanese patients with upper-respiratory tract infections. Anxiety and depression were measured with the Hospital Anxiety and Depression Scale (HADS). We determined the association among continuous variables using the Spearman correlation coefficient. Next, we used multiple regression analysis and selected all symptoms as independent variables. The SSAS was significantly associated with all somatic symptoms. It was also closely related to discomfort, but the SSAS was not significantly correlated with either anxiety or depression. All somatic symptoms were not significantly correlated with the objective physical findings. Multiple regression analyses indicated that amplification by SSAS was a statistically significant predictor of the patient's somatic symptoms and discomfort. The objective findings did not significantly predict the patient's symptoms. Our study provides some empirical evidence regarding psychological amplification of objective physical symptoms, as measured by SSAS, in Japanese patients with upper-respiratory tract infections. Our findings suggest that there is no difference in the role of amplification of bodily sensations between Japanese and North Americans.
