Norwegian reference data on the Fatigue Questionnaire and the Patient Health Questionnaire-9 and their interrelationship.

BACKGROUND: Population-based reference data on frequently used questionnaires are important for comparative purposes. Due to changes in health and lifestyles, such data should be updated every other decade. The objectives of this study were to establish Norwegian population-based reference data on the Fatigue Questionnaire (FQ) and the Patient Health Questionnaire-9 (PHQ-9) on depression, to compare the FQ-scores with our previous reference data from 1996, and to explore the relationship between the scores on these two instruments. METHODS: In 2015, a representative sample of 6,012 Norwegians aged 18-80 years was mailed a questionnaire including the FQ and the PHQ-9, and 36% responded. Complete FQ-scores were delivered by 2,041 subjects, and complete PHQ-9 scores by 2,086 subjects. The scores are displayed according to sex and 10-year age groups. RESULTS: Few 2015 mean scores of mental, physical, and total fatigue differed significantly from those of 1996, and the same was found for the prevalence rates of chronic fatigue. The exception was a significantly lower prevalence in 2015 of mean fatigue scores and prevalence of chronic fatigue in females ≥ 60 years. The prevalence of major depressive episode (MDE) based on the PHQ-9 sum score cut-off ≥ 10 was 5.9% for males and 9.8% for females, and 2.5% and 3.8% using a DSM-based algorithm with at least five endorsed criteria including either anhedonia or depressed mood. The correlation between the FQ and the PHQ-9 was 0.59, implying 36% shared variance. CONCLUSIONS: This study showed considerable interrelationship between the FQ and the PHQ-9 constructs. The reference data show that scores on the FQ have only improved significantly in persons aged 60 or more years between 1996 and 2015. Our prevalence findings of MDE based on the PHQ-9 are in accordance with the findings from other countries. The FQ and the PHQ-9 should be used together in epidemiological and clinical studies.

Challenges and Learning Needs for Providers of Advanced Cancer Care: Focus Group Interviews with Physicians and Nurses.

Background: Implementation of integrated oncology and palliative care improves patient outcomes but may represent a demanding task for health care providers (HCPs). Objective: To explore physicians' and nurses' perceived challenges and learning needs in their care for patients with advanced cancer, and to analyze how these perceptions can provide insight on how to improve care for patients with advanced cancer in an integrated care model. Methods: Residents in oncology, oncologists, nurses, and palliative care physicians were recruited to participate in focus group interviews. Six focus group interviews were conducted with 35 informants. Data were analyzed according to principles of thematic analysis. Results: The discussions in the interviews concerned three broad themes: an emphasis on patients' best interest, perceived as hindered by two sets of barriers; unsatisfactory organizational conditions such as time pressure, lack of referral routines, and few arenas for interdisciplinary collaboration, was perceived as one barrier. The other barrier was related to the appraisal of other HCPs' clinical practices. Participating HCPs expressed in general a positive self-view, but were more critical of other HCPs. Conclusion: Currently, implementation of measures to improve care for patients with advanced cancer appears to be challenging due to cultural and organizational factors, and how HCPs perceive themselves and other HCPs. HCPs' perception of challenges in patient care as not related to themselves (externalization) might be an essential obstacle. Interventions targeting both HCP-related and organizational factors are needed. Particularly important are measures aimed at reducing fragmentation and improving collaboration in care.

Life satisfaction in Norwegian medical doctors: a 15-year longitudinal study of work-related predictors.

BACKGROUND: Despite many recent studies on burn-out and dissatisfaction among American medical doctors, less is known about doctors in the Scandinavian public health service. The aims of this study were to analyse long-term work-related predictors of life satisfaction among established doctors in Norway and to identify predictors in a subgroup of doctors who reported a decline in life satisfaction. METHODS: Two nationwide cohorts of doctors (n = 1052), who graduated medical school 6 years apart, were surveyed at graduation from medical school (T1, 1993/94 and 1999), and 4 (T2), 10 (T3), and 15 (T4) years later. Work-related predictors of life satisfaction (three items) obtained at T2 to T4 were analysed. Individual and lifestyle confounders were controlled for using mixed-models repeated-measures analyses, and logistic regression analyses were applied to identify predictors of the decrease in life satisfaction. RESULTS: Ninety per cent (947/1052) responded at least once, and 42% (450/1052) responded at all four times. Work-related predictors of higher life satisfaction in the adjusted model were work-home stress (ß = - 0.20, 95% confidence interval [CI] = - 0.25 to - 0.16, p < 0.001), perceived job demands (ß = - 0.10, CI = - 0.15 to - 0.05, p < 0.001), and colleague support (ß = 0.05, CI = 0.04 to 0.07, p < 0.001). The new adjusted individual predictors that we identified included female gender, reality weakness trait, and problematic drinking behaviour. Neuroticism trait and low colleague support predicted a decrease in life satisfaction. CONCLUSIONS: Work-home stress, perceived job demands, and colleague support were the most important predictors of life satisfaction related to doctors' work. When personality traits were controlled for, female doctors were more satisfied with their life than male doctors. These findings suggest that improving work-related factors with targeted interventions, including a supportive work environment, may increase life satisfaction among doctors.

Patients with advanced cancer and depression report a significantly higher symptom burden than non-depressed patients.

OBJECTIVE: Clinical observations indicate that patients with advanced cancer and depression report higher symptom burden than nondepressed patients. This is rarely examined empirically. Study aim was to investigate the association between self-reported depression disorder (DD) and symptoms in patients with advanced cancer controlled for prognostic factors. METHOD: The sample included 935 patients, mean age 62, 52% males, from an international multicentre observational study (European Palliative Care Research Collaborative - Computerised Symptom Assessment and Classification of Pain, Depression and Physical Function). DD was assessed by the Patient Health Questionnaire-9 and scored with Diagnostic and Statistical Manual of Mental Disorder-5 algorithm for major depressive disorder, excluding somatic symptoms. Symptom burden was assessed by summing scores on somatic Edmonton Symptom Assessment Scale (ESAS) symptoms, excluding depression, anxiety, and well-being. Item-by-item scores and symptom burden of those with and without DD were compared using nonparametric Mann-Whitney U tests. The relative importance of sociodemographic, medical, and prognostic factors and DD in predicting symptom burden was assessed by hierarchical, multiple regression analyses. RESULT: Patients with DD reported significantly higher scores on ESAS items and a twofold higher symptom burden compared with those without. Factors associated with higher symptom burden were as follows. Diagnosis: lung (ß = 0.15, p < 0.001) or breast cancer (ß = 0.08, p < 0.05); poorer prognosis: high C-reactive protein (ß = 0.08, p < 0.05), lower Karnofsky Performance Status (ß = -0.14, p < 0.001), and greater weight loss (ß = -0.15, p < 0.001); taking opioids (ß = 0.11, p < 0.01); and having DD (ß = 0.23, p < 0.001). The full model explained 18% of the variance in symptom burden. DD explained 4.4% over and above that explained by all the other variables. SIGNIFICANCE OF RESULTS: Depression in patients with advanced cancer is associated with higher symptom burden. These results encourage improved routines for identifying and treating those suffering from depression.

Factors influencing doctors' counselling on patients' lifestyle habits: a cohort study.

BACKGROUND: Lifestyle changes are important for prevention and treatment of many common diseases, and doctors have an important role in the lifestyle counselling of patients. It is important to know more about factors influencing lifestyle counselling. AIM: To investigate the frequency of counselling about physical activity compared to that about alcohol habits; the impact of doctors' own physical activity and alcohol habits on patient counselling about these lifestyle dimensions; and whether perceived mastery of clinical work or vulnerable personality have a confounding or moderating effect on these associations. DESIGN & SETTING: In this nationwide cohort survey, a total of 978 doctors in Norway were surveyed by postal questionnaires in 1993/94 and 2014. The response rate was 562/978 (57%). METHOD: The outcome variables were questions on frequency of asking about alcohol and exercise habits. Explanatory variables were questions on doctors' own exercise habits, drinking habits (using Alcohol Use Disorders Identification Test [AUDIT]), perceived mastery of clinical work, vulnerable personality, and specialty. Associations were studied by linear regression analysis. RESULTS: Of the 526 responders, 307 (58%) reported asking usually/often about exercise habits, while n = 140/524 (27%) usually/often asked about alcohol habits. A doctor's own physical activity level was associated with frequency of asking about physical activity (unstandardised regression coefficient [B] = 0.07; 95% confidence intervals [CI] = 0.01 to 0.13). There were no significant associations between doctors' own lifestyle habits and counselling on alcohol habits. Doctors with low levels of vulnerability asked more frequently about physical activity, regardless of their own physical activity habits (F = 2.41, P = 0.048). CONCLUSION: Doctors' own lifestyles influenced their preventive counselling about physical activity, but not about alcohol. Vulnerability moderated these effects, indicating the importance of early interventions to help doctors with a vulnerable personality to handle negative criticism from patients.

Factors associated with low vs increased perceived mastery of clinical work over ten years of practice: a prospective study of Norwegian doctors.

BACKGROUND: A higher sense of mastery of doctors' clinical work could benefit not only their own mental health but also their work performance and patient care. However, we know little about factors associated with perceived mastery of clinical work among physicians. Our aim was therefore to study characteristics of those with stable low levels and of those with increased levels of mastery over a period of ten years of medical practice. METHODS: N = 631 doctors were surveyed in their final year of medical school in 1993/94 (T1) and 10 (T2), 15 (T3) and 20 (T4) years later. Low and increased perceived mastery of clinical work were measured between T2, T3 and T4. Response rates for all items measuring low and increased mastery were 238/522 (46%) and 256/522 (49%) respectively. The following explanatory variables were included: demographics, medical school factors, personality and contextual work-related and non-work-related factors. RESULTS: N = 73 (31%) of the doctors reported stable low mastery from T2 to T4. The following variables were significantly associated with low mastery in the adjusted analyses: vulnerability (OR: 1.30, P < .000, CI: 1.12 to 1.50), drinking alcohol to cope with stress during medical school (OR: 2.66, P = .04, CI: 1.03 to 6.85) and social support (OR: 0.78, P = .002, CI: 0.66 to 0.91). N = 39 (15%) reported increased mastery during the ten-year period from T2 to T4. Perceived job demands (OR: 0.66, P = .02, CI: 0.45 to 0.98) and taking up a leading position (OR: 3.04, P = .01, CI: 1.31 to 7.07) were associated with increased mastery after adjustment. CONCLUSIONS: Stable low sense of mastery over time is associated with having a vulnerable personality, a history of having used alcohol to cope with stress during medical school and lack of contemporary social support. Conversely, increased sense of mastery is associated with taking up a leading position and having the perception that job demands are decreasing over time. These findings indicate that perceived mastery of clinical work may not be a trait, but a state modifiable over time.

Medical school predictors of later perceived mastery of clinical work among Norwegian doctors: a cohort study with 10-year and 20-year follow-up.

OBJECTIVE: Doctors' self-perceived mastery of clinical work might have an impact on their career and patient care, in addition to their own health and well-being. The aim of this study is to identify predictors at medical school of perceived mastery later in doctors' careers. DESIGN: A cohort of medical students (n=631) was surveyed in the final year of medical school in 1993/1994 (T1), and 10 (T2) and 20 (T3) years later. SETTING: Nationwide healthcare institutions. PARTICIPANTS: Medical students from all universities in Norway. MAIN OUTCOME MEASURES: Perceived mastery of clinical work was measured at T2 and T3. The studied predictors measured at T1 included personality traits, medical school stress, perceived medical recording skills, identification with the role of doctor, hazardous drinking and drinking to cope, in addition to age and gender. Effects were studied using multiple linear regression models. RESULTS: Response rates: T1, 522/631 (83%); T2, 390/522 (75%); and T3, 303/522 (58%). Mean scores at T2 and T3 were 22.3 (SD=4.2) and 24.5 (3.0) (t=8.2, p<0.001), with no gender difference. Adjusted associations at T2 were: role identification (ß=0.16; p=0.006; 95% CI 0.05 to 0.28), perceived medical recording skills (ß=0.13; p=0.02; 95% CI 0.02 to 0.24) and drinking to cope (ß=-2.45; p=0.001; 95% CI -3.88 to -1.03). Adjusted association at T3 was perceived medical recording skills (ß=0.11; p=0.015; 95% CI 0.02 to 0.21). CONCLUSIONS: Perceived medical recording skills and role identification were associated with higher perceived mastery. Medical schools should provide experiences, teaching and assessment to enhance students' physician role identification and confidence in their own skills. Drinking to cope was associated with lower perceived mastery, which indicates the importance of acquiring healthier coping strategies in medical school.

Risk Factors Measured During Medical School for Later Hazardous Drinking: A 10-year, Longitudinal, Nationwide Study (NORDOC).

AIMS: To investigate the prevalence and temporal patterns of hazardous drinking and risk factors during medical school for future hazardous drinking among doctors. METHODS: Two cohorts of graduating medical students (N = 1052) from all four Norwegian universities (NORDOC) were surveyed in their final year of medical school training (1993/94 and 1999) (T1) and again 4 (T2) and 10 (T3) years later. Longitudinally, 53% (562/1052) of the sample responded at all three time points. Hazardous drinking was defined as drinking five or more drinks during one session at least 2-3 times per month. Predictors of hazardous drinking, identified by logistic regression models after controlling for cohort, included a parental history of alcohol problems, having children, no religious activity, use of alcohol to cope with tension and some personality traits. RESULTS: There was a significant decline in the prevalence of hazardous drinking from T1 (14%) to T2 (10%) but not from T2 to T3 (8%). Approximately 23% of hazardous drinkers at T1 remained hazardous drinkers at T3 (N = 18). At T2, significant adjusted predictors included male gender (OR = 2.0, P = 0.04), use of alcohol as a coping strategy (OR = 2.2, P = 0.03) and hazardous drinking at T1 (OR = 9.8, P < 0.001). The significant adjusted predictors at T3 included older age (OR = 1.1, P = 0.01), male gender (OR = 3.6, P = 0.002) and hazardous drinking at T1 (OR = 7.5, P < 0.001). CONCLUSIONS: Hazardous drinking and drinking to cope with tension during medical school were the most important predictors of later hazardous drinking and should be targets of preventive efforts in medical schools.
