The relationship between burnout, personality traits, and medical specialty. A national study among Dutch residents.

Purpose: To examine the associations between residents' personality traits, type of specialty, and symptoms of burnout. Method: A cross-sectional online survey among Dutch residents was conducted (see Supplementary Material ). The 20-item Dutch translation of the Maslach Burnout Inventory was used to ascertain burnout. Personality traits were assessed with the 44-item Dutch Big Five Inventory. Logistic regression analyses, including all five personality traits, were used to assess associations with burnout. Analyses were stratified by specialties. Results: One thousand two hundred thirty one residents participated, 185 (15.0%) of whom met the criteria for burnout. Neuroticism was significantly associated with resident burnout in all specialties, more strongly in supportive (odds ratio (OR) 6.19, 95% CI 2.12-18.12) and surgical (OR 4.37, 95% CI 1.76-10.86) than in medical residents (OR 1.99, 95% CI 1.22-3.24). Extraversion was significantly associated with less burnout in surgical residents (OR 0.26, 95% CI 0.13-0.58). These findings remained highly significant after controlling for gender, overtime, autonomy at work, satisfaction between work and private life, and the perceived quality of the learning environment. Conclusions: Burnout risk was associated with personality traits in residents. Consistently, residents scoring high on neuroticism reported more burnout. Extraverted surgical residents were less susceptible to burnout. Residents scoring high on neuroticism may require more intense monitoring during their training years.

The contribution of work characteristics, home characteristics and gender to burnout in medical residents.

Burnout is highly prevalent in medical residents. In order to prevent or reduce burnout in medical residents, we should gain a better understanding of contributing and protective factors of burnout. Therefore we examined the associations of job demands and resources, home demands and resources, and work-home interferences with burnout in male and female medical residents. This study was conducted on a nation-wide sample of medical residents. In 2005, all Dutch medical residents (n = 5245) received a self-report questionnaire on burnout, job and home demands and resources and work-home interference. Path analysis was used to examine the associations between job and home characteristics and work-home interference and burnout in both males and females. In total, 2115 (41.1 %) residents completed the questionnaire. In both sexes emotional demands at work and the interference between work and home were important contributors to burnout, especially when work interferes with home life. Opportunities for job development appeared to be an important protective factor. Other contributing and protective factors were different for male and female residents. In females, social support from family or partner seemed protective against burnout. In males, social support from colleagues and participation in decision-making at work seemed important. Effectively handling emotional demands at work, dealing with the interference between work and home, and having opportunities for job development are the most essential factors which should be addressed. However it is important to take gender differences into consideration when implementing preventive or therapeutic interventions for burnout in medical residents.

Relationship between plasma homovanillic acid and outcome in patients with psychosis spectrum disorders.

BACKGROUND: Psychosis spectrum disorders, especially schizophrenia, have been linked to disturbed dopaminergic activity in the brain. Plasma homovanillic acid (pHVA) levels partly represent dopaminergic metabolism in the central nervous system. In the present study associations between (changes in) pHVA levels, symptom severity and symptomatic improvement in patients with psychoses were investigated. METHODS: From a total of 80 patients, 58 fulfilled all inclusion criteria and their symptom profile and severity were assessed by means of the Comprehensive Assessment of Symptoms and History (CASH), the Positive and Negative Syndrome Scale (PANSS) and the Clinical Global Impression Scale for Severity and Improvement (CGI-S/CGI-I) at baseline and after 6 weeks of antipsychotic treatment. After inclusion, all patients were prescribed first- or second-generation antipsychotics by their treating psychiatrist. A total of 12 patients had first-episode psychosis (FEP). At both time points, pHVA levels were measured. Subsequently, pHVA levels were compared with an age-matched control sample and changes in pHVA levels (ΔpHVA) after treatment were associated with clinical parameters. RESULTS: Before analyses, data were scrutinized for possible confounders, particularly gender, smoking, medication status (including antipsychotic class), and recent drug use. The pHVA levels in patients were not different from those in controls. Treatment resulted in a significant decrease of all parameters. Symptomatic improvement as well as ΔpHVA was most pronounced in FEP patients. CONCLUSION: These findings show that patients with FEP have a more favourable outcome than non-FEP patients and that greater ΔpHVA also suggests that FEP patients still have the capacity to adjust dopaminergic neurotransmission.

BDNF and S100B in psychotic disorders: evidence for an association with treatment responsiveness.

OBJECTIVE: Brain-derived neurotrophic factor (BDNF) and S100B are involved in brain plasticity processes and their serum levels have been demonstrated to be altered in patients with psychoses. This study aimed to identify subgroups of patients with psychotic disorders across diagnostic boundaries that show a specific symptom profile or response to treatment with antipsychotics, by measuring serum levels of BDNF and S100B. METHODS: The study sample consisted of 58 patients with DSM-IV psychotic disorders. Comprehensive Assessment of Symptoms and History (CASH), Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression scale for severity and improvement (CGI-S/CGI-I) were applied at baseline and after 6 weeks of antipsychotic treatment. At both time points, serum levels of BDNF and S100B were measured and compared with a matched control sample. RESULTS: Baseline BDNF and S100B levels were significantly lower in patients as compared with controls and did not change significantly during treatment. Dividing the patient sample according to baseline biochemical parameters (low and high 25% and middle 50%), no differences in symptom profiles or outcome were found with respect to BDNF. However, the subgroups with low and high S100B levels had higher PANSS scores than the middle subgroup. In addition, the high subgroup still showed significantly more negative symptoms after treatment, whereas the low subgroup showed more positive symptoms compared with the other subgroups. CONCLUSION: Serum levels of BDNF and S100B are lowered in patients with psychotic disorders across diagnostic boundaries. The differences between high and low S100B subgroups suggest a relationship between S100B, symptom dimensions and treatment response, irrespective of diagnostic categories.

Cardiometabolic comorbidity in antipsychotic treated patients: need for systematic evaluation and treatment.

OBJECTIVE: The aim of the study was to determine the prevalence of cardiometabolic dysregulations and their somatic treatment regimens in a group of psychiatric patients treated with antipsychotics. METHODS: In a naturalistic cohort study, baseline cardiometabolic parameters were measured in 543 outpatients. After one year, a second assessment was performed in 220 patients out of the total sample. In addition, it was investigated whether in patients with somatic comorbidities adequate treatment was prescribed. RESULTS: In this cohort, about half of the patients fulfilled the criteria for metabolic syndrome. Only a limited number of patients, however, received pharmacologic treatment for individual risk factors: About 19% for hypercholesterolemia, 26% for hypertension, and 52% for diabetes. Non-treated patients were significantly younger than treated patients. Follow-up data show that the course of the cardiometabolic parameters can be dynamic. CONCLUSIONS: Cardiometabolic risk factors are highly prevalent in psychiatric patients treated with antipsychotic drugs. Unfortunately, adequate treatment of cardiometabolic comorbidity in these relatively young patients is seriously hampered. Thus, specific guidelines for psychiatric patients have to be developed taking into account the high cardiovascular risk at a relatively young age and potential pharmacokinetic interactions between psychotropics and somatic compounds. Moreover, integration of psychiatric and physical health care systems for patients with mental disorders is urgently needed.

Working memory in schizophrenia: a systematic study of specific modalities and processes.

Although many researchers agree that working memory (WM) impairments are a core symptom of schizophrenia, it remains unclear how the disturbances on specific WM components relate to one another. In this study, we presented a Delayed-Matching-To-Sample task to 24 schizophrenia patients and 24 healthy controls, matched on demographical variables. Verbal and visuospatial WM performance was investigated with pseudowords and Chinese characters as stimuli, respectively. Processing demands (maintenance and manipulation, measured with delay and mental rotation) were low or high. Reaction time and accuracy were recorded. All experimental factors had significant effects. In general, patients were slower and less accurate than controls. Patients were especially slower on verbal tasks but they were not less accurate. Accuracy differences did not increase when either maintenance or manipulation demands increased alone but they did when both maintenance and manipulation demands increased simultaneously. These findings indicate that performance impairment in patients was non-specific and that no specific deficit of any WM component was observed.

Associations Between Maternal Depression, Antidepressant Use During Pregnancy, and Adverse Pregnancy Outcomes: An Individual Participant Data Meta-analysis.

OBJECTIVE: To evaluate the associations of depressive symptoms and antidepressant use during pregnancy with the risks of preterm birth, low birth weight, small for gestational age (SGA), and low Apgar scores. DATA SOURCES: MEDLINE, EMBASE, ClinicalTrials.gov, and PsycINFO up to June 2016. METHODS OF STUDY SELECTION: Data were sought from studies examining associations of depression, depressive symptoms, or use of antidepressants during pregnancy with gestational age, birth weight, SGA, or Apgar scores. Authors shared the raw data of their studies for incorporation into this individual participant data meta-analysis. TABULATION, INTEGRATION, AND RESULTS: We performed one-stage random-effects meta-analyses to estimate odds ratios (ORs) with 95% CIs. The 215 eligible articles resulted in 402,375 women derived from 27 study databases. Increased risks were observed for preterm birth among women with a clinical diagnosis of depression during pregnancy irrespective of antidepressant use (OR 1.6, 95% CI 1.2-2.1) and among women with depression who did not use antidepressants (OR 2.2, 95% CI 1.7-3.0), as well as for low Apgar scores in the former (OR 1.5, 95% CI 1.3-1.7), but not the latter group. Selective serotonin reuptake inhibitor (SSRI) use was associated with preterm birth among women who used antidepressants with or without restriction to women with depressive symptoms or a diagnosis of depression (OR 1.6, 95% CI 1.0-2.5 and OR 1.9, 95% CI 1.2-2.8, respectively), as well as with low Apgar scores among women in the latter group (OR 1.7, 95% CI 1.1-2.8). CONCLUSION: Depressive symptoms or a clinical diagnosis of depression during pregnancy are associated with preterm birth and low Apgar scores, even without exposure to antidepressants. However, SSRIs may be independently associated with preterm birth and low Apgar scores. SYSTEMATIC REVIEW REGISTRATION: PROSPERO, CRD42016035711.

Burnout and engagement among resident doctors in the Netherlands: a national study.

OBJECTIVES: This study was performed in order to gather insight into the well-being of Dutch medical residents. METHODS: In 2005, all Dutch residents registered through the Medical Registration Committee (n = 5245) were sent a self-report questionnaire to assess socio-demographic and work-related characteristics, burnout and engagement. RESULTS: Of the 5140 eligible residents, 2115 completed the questionnaire (41%). Of those, 21% fulfilled the criteria for moderate to severe burnout and 27% were highly engaged with their work. Women reported more emotional exhaustion and less depersonalisation than men; age was weakly but significantly related to depersonalisation, and married residents and parents reported less depersonalisation than their single or childless counterparts. More men than women were found to be highly engaged and men specifically reported more vigour. Number of years in training was weakly but significantly related to absorption. With regard to occupational risk factors, significant between-group differences were found for the effects of clinical setting on emotional exhaustion, engagement, vigour and absorption. Residents in training in a mental health clinic were most emotionally exhausted and those in a rehabilitation centre were least engaged. General surgery represented the specialty with the lowest number of residents suffering from burnout, followed by obstetrics and gynaecology and any supportive specialty. General surgery residents were also found to be more highly engaged, vigorous, dedicated and absorbed than others. CONCLUSIONS: As more than a fifth of the medical residents who responded could be diagnosed as suffering from burnout, we conclude that this problem needs addressing in the Dutch health care system, especially given that a relationship was proven between burnout and suboptimal patient care. We must look for solutions and interventions which will improve the work situation of medical residents. Striving for healthy workers in health care has to become daily practice.

Does extracranial arterial pathology play a role in late-onset psychiatric disorders?

INTRODUCTION: Carotid interventions are commonly performed to reduce the risk of disabling stroke and stroke-related death. Carotid interventions may also have an effect on cognitive functions. Mental disorders in the elderly have been related to structural brain pathology. This review of literature was performed to test the hypothesis that atherosclerotic lesions in the carotid and vertebral arteries may have an impact on the development and treatment of late-onset psychiatric disorders. METHODS: A literature search identified articles focusing on the key issues using the Pubmed and Cochrane databases. RESULTS: Cardiovascular risk factors seem to be increased in patients with late-onset mania, depression, and schizophrenia. Cerebral infarctions, especially right-sided, have repeatedly been associated with various psychiatric disorders. Several case reports suggest that chronic cerebral hypoperfusion may also induce psychiatric disease and that these disorders might disappear after reconstruction. CONCLUSIONS: There seems to be an association between occlusive carotid and vertebral disease and the late-onset of various psychiatric disorders. Both thromboembolic and chronic cerebral hypoperfusion might contribute to its pathophysiology. This group of patients might benefit from an intervention.

The relationship between reciprocity and burnout in Dutch medical residents.

OBJECTIVE: This study examined reciprocity in medical residents' relationships with supervisors, fellow residents, nurses and patients, and associations between reciprocity and burnout. Furthermore, we considered if a discrepancy between the perceived and preferred levels of reciprocity influenced the level of burnout complaints. METHODS: In 2003, self-report questionnaires were sent to the homes of all 292 medical residents at the University Medical Centre Groningen (UMCG), Groningen, the Netherlands. Reciprocity was measured with a single-item reciprocity scale based on the Hatfield Global Measure of Equity Scale. The Utrecht Burn-Out Scale (UBOS/MBI-HHS) was used to measure burnout. RESULTS: A total of 158 residents participated in the study. Those who reported under-benefiting in the relationship with supervisors perceived significantly more emotional exhaustion and depersonalisation than those who perceived a reciprocal relationship. Residents who indicated that they over-benefited in the relationship with nurses reported more emotional exhaustion than residents who perceived a reciprocal relationship and less personal accomplishment than residents who perceived a reciprocal relationship or under-benefit. No differences on the burnout subscales were found between residents who perceived their relationships with patients and fellow residents to be reciprocal and those who considered they under- or over-benefited. The greater the discrepancy between perceived and preferred reciprocity in the relationship with the supervisor, the more emotional exhaustion residents reported. CONCLUSIONS: Perceptions of reciprocity in relationships with supervisors and nurses had particular influence on the level of burnout complaints among residents. The discrepancy between the impacts of perceived and preferred reciprocity on burnout was negligible and the only significant relationship to emerge concerned that with emotional exhaustion.

The learning environment and resident burnout: a national study.

INTRODUCTION: Concerns exist about the negative impact of burnout on the professional and personal lives of residents. It is suggested that the origins of burnout among residents are rooted in the learning environment. We aimed to evaluate the association between the learning environment and burnout in a national sample of Dutch residents. METHODS: We conducted a cross-sectional online survey among all Dutch residents in September 2015. We measured the learning environment using the three domain scores on content, organization, and atmosphere from the Scan of Postgraduate Educational Environment Domains (SPEED) and burnout using the Dutch version of the Maslach Burnout Inventory (UBOS-C). RESULTS: Of 1,231 responding residents (33 specialties), 185 (15.0%) met criteria for burnout. After adjusting for demographic (age, gender and marital status) and work-related factors (year of training, type of teaching hospital and type of specialty), we found a consistent inverse association between SPEED scores and the risk of burnout (aOR 0.54, 95% CI 0.46 to 0.62, p < 0.001). DISCUSSION: We found a strong and consistent inverse association between the perceived quality of the learning environment and burnout among residents. This suggests that the learning environment is of key importance in preventing resident burnout.

The relationship between work and home characteristics and work engagement in medical residents.

INTRODUCTION: Work engagement is important for medical residents and the healthcare organizations they work for. However, relatively little is known about the specific predictors of work engagement in medical residents. Therefore, we examined the associations of work and home characteristics, and work-home interference with work engagement in male and female residents. METHODS: This study was conducted on a nationwide sample of medical residents. In 2005, all Dutch medical residents (n = 5245) received a self-report questionnaire. Path analysis was used to examine the associations between the potential predictors and work engagement. RESULTS: In total, 2115 (41.1%) residents completed the questionnaire. Job characteristics, home characteristics and work-home interference were associated with work engagement. Important positive contributing factors of work engagement were opportunities for job development, mental demands at work, positive work-home interference and positive home-work interference. Important negative contributing factors were emotional demands at work and negative home-work interference. The influence of these factors on work engagement was similar in male and female residents. DISCUSSION: Opportunities for job development and having challenging work are of high relevance in enhancing work engagement. Furthermore, interventions that teach how to deal skilfully with emotional demands at work and home-work interference are expected to be the most effective interventions to enhance work engagement in medical residents.

Khat and mushrooms associated with psychosis.

OBJECTIVE: This paper describes two cases with khat- and two with psilocybin-induced psychoses and draws attention to the medical and social consequences of the use of these drugs. METHOD: Two male patients are presented who developed relapsing and short-lasting psychotic episodes after chewing kath leaves. In addition, two male patients are reported who showed an acute exacerbation of psychosis after ingestion of psilocybin mushrooms. In addition, a review of the literature is presented. RESULTS: The khat-induced psychotic symptoms disappeared without any treatment within one week. One of the patients with a psilocybin-induced psychosis was treated with risperidone. In the other, symptomatology subsided in a few days. No somatic medical complications occurred. CONCLUSION: Adequate psychiatric diagnosis and treatment of the psychoses and the negative social consequences of the use of these drugs are stressed as well as the delineation from functional psychoses in cases of chronic use. The latter applies to patients with psychiatric comorbidity in particular.

Burnout in medical residents: a review.

OBJECTIVES: This study aimed to review current knowledge on burnout in medical residents, including reported prevalence rates, and to establish which risk and resistance factors contribute to or prevent burnout in medical residents. METHODS: We conducted a comprehensive search of the literature published between 1975 and 2005, using the Medline, EMBASE (from 1989) and PsychINFO databases. RESULTS: A total of 19 studies met our inclusion criteria. Only 5 studies appeared to meet more than 2 of the Cochrane quality criteria. The different studies report widely varying burnout rates among medical residents, ranging from 18% to 82%. Predictors of burnout can be characterised as either occupational or individual. Inconsistent results were reported with regard to the effects of some of these factors on burnout. Four of the 16 occupational risk factors appeared to be strongly related to burnout. The 11 individual risk factors examined were only weakly or moderately related to burnout. CONCLUSIONS: Research on burnout among medical residents is scarce. The weak quality of the studies, the wide variety and limited predictive power of the predictor variables included and the inconsistent findings illustrate the need for a more systematic design with regard to future research among medical residents. A future research model should take account of the individual, occupational and training demands experienced by medical residents.

No association between 12 dopaminergic genes and schizophrenia in a large Dutch sample.

It has been suggested that genes involved in dopamine neurotransmission contribute to the pathogenesis of schizophrenia. However, reported associations of the disorder with genetic markers in dopaminergic genes have yielded inconsistent results. Possible explanations are differences in phenotyping, genetic heterogeneity, low marker informativity, and the use of small sample sizes. Here, we present a two-stage analysis of 12 dopaminergic genes in a large sample of Dutch schizophrenic patients. To reduce genetic heterogeneity, only patients with at least three Caucasian grandparents of Dutch ancestry were ascertained. An efficient genotyping strategy was used, in which polymorphic microsatellite markers were first screened for association in DNA pools. Promising results were followed up by individual genotyping in an extended sample. The pooled samples consisted of 208 schizophrenic patients and 288 unmatched control individuals. For each of the genes, more than one microsatellite marker was selected where possible, either intragenic or close to the gene. After correcting for multiple testing, significantly different allele frequencies were detected for DRD5 marker D4S615. Subsequently, we individually genotyped this particular marker and another DRD5 marker, as well as a DRD3 marker that could not be analyzed using the pooling strategy. This was done in an extended sample of 282 schizophrenic patients and a control sample of 585 individuals. In this second stage of the study, we found no association between these three markers and schizophrenia. The results of our comprehensive analysis provide no evidence for association between schizophrenia and 12 dopaminergic genes in a large Dutch sample.
