Burnout among intensive care nurses, physicians and leaders during the COVID-19 pandemic: A national longitudinal study.

BACKGROUND: Burnout is frequent among intensive care unit (ICU) healthcare professionals and may result in medical errors and absenteeism. The COVID-19 pandemic caused additional strain during working hours and also affected off-duty life. The aims of this study were to survey burnout levels among ICU healthcare professionals during the first year of COVID-19, describe those who reported burnout, and analyse demographic and work-related factors associated with burnout. METHODS: This was a national prospective longitudinal cohort study of 484 nurses, physicians and leaders working in intensive care units with COVID-19 patients in Norway. Burnout was measured at 6- and 12-month follow-up, after a registration of baseline data during the first months of the COVID epidemic. The Copenhagen Burnout Inventory (CBI), was used (range 0-100), burnout caseness defined as CBI ≥50. Bi- and multivariable logistic regression analyses were performed to examine baseline demographic variables and work-related factors associated with burnout caseness at 12 months. RESULTS: At 6 months, the median CBI score was 17, increasing to 21 at 12 months (p = .037), with nurses accounting for most of the increase. Thirty-two per cent had an increase in score of more than 5, whereas 25% had a decrease of more than 5. Ten per cent reported caseness of burnout at 6 months and 14% at 12 months (n.s.). The participants with burnout caseness were of significantly lower age, had fewer years of experience, reported more previous anxiety and/or depression, more moral distress, less perceived hospital recognition, and more fear of infection in the bivariate analyses. Burnout was the single standing most reported type of psychological distress, and 24 out of 41 (59%) with burnout caseness also reported caseness of anxiety, depression and/or post-traumatic stress disorder (PTSD) symptoms. Multivariate analysis showed statistically significant associations of burnout caseness with fewer years of professional experience (p = .041) and borderline significance of perceived support by leader (p = .049). CONCLUSION: In Norway, a minority of ICU nurses, physicians and leaders reported burnout 1 year into the pandemic. A majority of those with burnout reported anxiety, depression and/or PTSD symptoms combined. Burnout was associated with less years of professional experience.

Electrocardiographic Characteristics in 438 Neonates with Atrial Septal Defects.

Arrhythmias and electrocardiographic (ECG) abnormalities are common among patients with atrial septal defects (ASDs). We studied a large cohort of neonates with ASDs to investigate whether ECG abnormalities are present at this early stage or develop later, secondary to hemodynamic changes. We analyzed the echocardiograms and ECGs from the Copenhagen Baby Heart Study, a population-based cohort study. We compared ECG characteristics of 438 neonates with secundum ASDs to 1314 matched controls. In subgroup analyses, we investigated whether electrocardiographic characteristics were associated with age at examination. Neonates with ASDs (median age, 11 days; males, 51%) had longer P-wave durations (58 vs. 56 ms, p < 0.001), PR intervals (100 vs. 96 ms, p < 0.001), and a more rightward-shifted QRS axis (116 vs. 114 degrees, p = 0.032) compared to controls (median age, 10 days; males, 51%). There were no differences between cases and controls in the P-wave area, amplitude, or axis. Subgroup analyses showed that the differences in P-wave duration and PR interval were present in neonates examined in the first week after birth. The difference in the QRS axis was not found in neonates examined this early but was found in neonates examined at age two to four weeks. In conclusion, ASDs are associated with ECG changes from the neonatal phase. The P-wave duration and PR interval are longer in neonates with ASDs when compared to controls as early as the first week after birth, indicating that these changes are not purely secondary, but that neonates with an ASD have altered cardiac electrical activity.ClinicalTrials.gov Identifier NCT02753348 (April 27, 2016).

Timber supply through time - Copenhagen waterfronts under scrutiny.

Dendrochronology is not a new method for attaining high-precision dates for archaeological and historic remains of timber. But the extent to which dendrochronology is utilized to attain detailed precision of the dating of complex wooden structures can suffer from the fact that the method is often applied in commercial archaeology, where the extent of analysis is severely limited by cost constraints. Instead of lamenting the potentially lost levels of detail that might have slipped through over the years, it is hoped that by presenting the potential of high chronological precision, that necessitates extensive sampling of timber and wood remains on archaeological sites, a new future will be promoted, in which new wide-ranging sampling strategies will become a more normal practice in archaeology, in both the research and commercial spheres. In this paper, I present some case studies where extensive tree-ring analysis of well-preserved wood remains have resulted in annual chronological detail, allowing an insight into the processes of building, and into the duration of structures that comprised the built environment of past peoples' lives. In addition, we should not discuss precision dating for urban archaeological study without also touching on the subject of timber trade and timber provenance. Tree-ring studies are increasingly providing us with high precision provenance identification, not just for shipwrecks, barrels and other 'portable' objects. It is also allowing us to map trade in bulk structural timber. These analyses are providing us with insights into links between territories.

Predicting the occurrence of in-season groin pain in male high school soccer players: a cohort study.

[Purpose] This study investigated whether pre-season HAGOS (Japanese Copenhagen Hip and Groin Outcome Scores) and eccentric muscle strength of the hip muscles predict in-season groin pain incidences in high school soccer players. [Participants and Methods] This study had a cohort design. The participants were male high school players under 18 years playing in the Japan Soccer League, which is an elite-level soccer league of that age category in Japan. The HAGOS and the strength of hip abductor and adductor muscles in eccentric contraction were measured before the season, and hip and groin pain incidences were recorded during the season. Multiple logistic regression analysis was performed to investigate the factors derived from the pre-season HAGOS and hip muscle strength tests, presumably pertaining to the development of in-season groin pain. [Results] The eccentric adductor muscle strength of the dominant leg and the HAGOS were selected as factors associated with groin pain during the season. [Conclusion] Low pre-season HAGOS and weak dominant-leg eccentric adductor muscle strength were suggested as factors to predict in-season groin pain occurrence in male high school soccer players.

Electrocardiographic characteristics of newborns with ventricular septal defects: a Copenhagen Baby Heart Study.

Ventricular septal defects (VSD) represent the most common congenital heart defect in newborns. We assessed the electrocardiographic characteristics of newborns with VSDs in a general population sample. The Copenhagen Baby Heart Study is a prospective population-based cohort study offering cardiac evaluation of newborns. Echocardiograms and electrocardiograms were obtained within 30 days after birth and systematically analysed. A VSD was identified in 530 newborns (mean age 11 ± 7 days, 42% boys). Newborns with VSDs had a more left-shifted QRS axis (116 ± 34 vs. 120 ± 3°, p = 0.02), and a higher S-wave amplitude in V1 (721 ± 584 vs. 636 ± 549 µV, p = 0.001) than controls. The largest differences were found in newborns with large or perimembraneous VSDs with a higher frequency of left axis deviation, higher S-wave amplitudes in V1, and higher R- and S-wave amplitudes in V6 compared with controls. R-waves in V1 and V6 were significantly associated to left ventricular mass, whereas S-waves in V1 and V6 were dependent on left ventricular end-diastolic diameter on echocardiography.  Conclusion: Newborns with VSDs showed significant differences in QRS axis, and R- and S-wave precordial amplitudes compared to matched controls. Perimembranous and large VSDs had the greatest effect on the neonatal ECG. What is Known: • Ventricular septal defects in newborns are prevalent and may affect cardiac function and structure. What is New: • The Copenhagen Baby Heart Study is the largest study including a cohort of unselected newborns undergoing postnatal cardiac examination. • We found that newborns with VSD showed significant electrocardiographic differences depending on size and type of VSD compared with healthy newborns.

Knee function, quality of life, pain, and living conditions after distal femoral resection knee arthroplasty for non-tumor indications.

BACKGROUND: Distal femoral resection knee arthroplasty is a limb salvage procedure. The impact of distal femoral resection arthroplasty on patient function and health status is unknown. The aim of this study was to report knee function, quality of life, knee pain, and living conditions after distal femoral resection knee arthroplasty for non-tumor indications. METHODS: Of 52 patients (52 knees) undergoing distal femoral resection knee arthroplasty in a single institution between 2012 and 2021, 22 were excluded as 3 patients had ≤90 days follow-up, 6 had died, and 13 declined or were unable to participate for unrelated reasons. Thus, 30 patients were included and interviewed by telephone in March 2021 (mean follow-up 3.5 years after surgery). Patient completed the Oxford Knee Score (0-48, 48 best), EQ-5D-5L, and the Copenhagen Knee ROM, and information on pain and living conditions was obtained. RESULTS: The mean age was 67.9 years (SD 13.6), and 21 (70%) were female. Mean total Oxford Knee Score was 29.9 (SD 10.5), mean Copenhagen Knee ROM flexion was 116° (SD 21.6), and mean extension was - 2° (SD10.1). Mobility aids were used by 18 (60%) patients, i.e. a cane (30%), walker (26.7%) or wheelchair (3.3%). Mean EQ-5Dindex score was 0.70 (SD 0.22) and mean EQ-5D VAS score was 55.4 (SD 23.9). Nine (30%) patients used paracetamol or NSAID and 2 (6.7%) used opioids for knee pain. Mean VAS knee pain score was 1.30 (SD 2.2) at rest and 2.8 (SD 3.1) when walking. Most (90%) patients lived in their own home, with only 3 patients in nursing homes. Two-thirds (66.7%) required no home care, 5 (16.6%) received home care 1-2 times over 2 weeks, and 5 (16.6%) every day. CONCLUSION: Distal femoral resection knee arthroplasty appears to be a viable treatment option for non-tumor indications. Acceptable patient outcomes were achieved in terms of functional status and quality of life, especially considering treatment alternatives such as femoral amputation.

Comparison of the risk of ovarian malignancy algorithm and Copenhagen Index for the preoperative assessment of Japanese women with ovarian tumors.

OBJECTIVE: To compare the risk of ovarian malignancy algorithm (ROMA) and Copenhagen Index (CPH-I) in their ability to distinguish epithelial ovarian cancer (EOC) and malignant ovarian tumors (MLOT) from benign ovarian tumors (BeOT) in Japanese women. METHODS: Patients with pathologically diagnosed ovarian tumors were included in this study. The study validated the diagnostic performance of ROMA and CPH-I. RESULTS: Among the 463 Japanese women included in this study, 312 had BeOT, 99 had EOC, and 52 had other MLOT. The receiver-operator characteristic (ROC) area under the curve (AUCs) of ROMA (0.89) and CPH-I (0.89) for distinguishing EOC from BeOT were significantly higher than that of CA125 (0.82) (CA 125 vs. ROMA; p = 0.002, vs. CPH-I; p < 0.001). The ROC-AUCs of ROMA (0.82) and CPH-I (0.81) for distinguishing MLOT from BeOT were significantly higher than that of CA125 (0.75) (CA 125 vs. ROMA: p = 0.003, vs. CPH-I: p < 0.001). The sensitivity (SN)/specificity (SP) of ROMA and CPH-I for distinguishing EOC from BeOT at standard cut-off points were 69%/90%, and 69%/90%, respectively, those for distinguishing MLOT from BeOT were 54%/90%, and 55%/90%, respectively. CONCLUSION: ROMA and CPH-I performed comparably well and better than CA125 in distinguishing EOC from BeOT in Japanese women. ROMA and CHP-I should be used with caution in practical situations, where all histological possibilities for must be considered, because the SNs of ROMA and CPH-I were only 54% and 55%.

Diagnostic performance of CA125, HE4, ROMA, and CPH-I in identifying primary ovarian cancer.

AIMS: To evaluate the ability of carbohydrate antigen 125 (CA125), human epididymis protein 4 (HE4), risk of ovarian malignancy algorithm (ROMA), and Copenhagen Index (CPH-I) to identify primary ovarian cancer (OC) from borderline and benign ovarian tumors (OTs) and explore ideal cutoff points. METHODS: A total of 684 OTs containing 276 OC patients, 116 ovarian borderline OTs and 292 benign OTs patients who underwent surgery in our hospital were included. We retrospectively searched the results of CA125 and HE4 before patients' surgery from the hospital's electronic medical records system. ROMA and CPH-I were calculated according to their menopausal status and age, respectively. Diagnostic performance of these four were assessed by drawing receiver operating characteristic (ROC) curves. RESULTS: CA125, HE4, ROMA, and CPH-I were all significantly higher in OC women compared with borderline OTs (p < 0.001), followed by benign OTs (p < 0.001). Area under the curves (AUCs) for distinguishing OC were 0.850 (0.818-0.882), 0.891 (0.865-0.916), 0.910 (0.888-0.933) and 0.906 (0.882-0.930), respectively, and the corresponding ideal cutoff values for CA125, HE4, ROMA, and CPH-I were 132.5, 68.6, 23.8, and 6.4, respectively. The difference between ROMA and CPH-I was not significant (p = 0.97), but both were higher than CA125 and HE4 (p < 0.05). HE4 showed a significantly higher AUC than CA125 (p < 0.05). For postmenopausal women, CA125 performed equivalently to ROMA (p = 0.73) and CPH-I (p = 0.91). CONCLUSIONS: In identifying patients with OC, ROMA and CPH-I outperformed single tumor marker. The diagnostic performance of HE4 was significantly higher than that of CA125. CA125 was more suitable for postmenopausal women.

Atrial Septal Defect: Larger Right Ventricular Dimensions and Atrial Volumes as Early as in the First Month After Birth-a Case-Control Study Including 716 Neonates.

Atrial septal defect (ASD) is characterized by a left-to-right shunt causing dilatation of the right atrium and right ventricle as well as pulmonary hyperperfusion. The detection of ASDs often occurs late in childhood or adulthood. Little is known about cardiac structure and function in neonates with ASD.We analyzed neonatal echocardiograms from the Copenhagen Baby Heart Study, a multicenter, population-based cohort study of 27,595 neonates. We included 716 neonates with secundum-type ASDs and matched them 1:1 on sex and age at examination with neonates without ASD from the same birth cohort. Neonates with an ASD (median age 11 days, 52% female) had larger right ventricular (RV) dimensions than matched controls (RV longitudinal dimension end-diastole: 27.7 mm vs. 26.7 mm, p < 0.001; RV basal dimension end-diastole: 14.9 mm vs. 13.8 mm, p < 0.001; and RV outflow tract diameter 13.6 mm vs. 12.4 mm, p < 0.001). Atrial volumes were larger in neonates with ASD compared to controls (right atrial end-systolic volume: 2.9 ml vs. 2.1 ml, p < 0.001; and left atrial end-systolic volume 2.0 ml vs. 1.8 ml, p < 0.001). Tricuspid annular plane systolic excursion was larger in neonates with ASD than in controls (10.2 mm vs. 9.6 mm, p < 0.001). Left ventricular dimensions and function did not differ between neonates with ASD and controls. In conclusion, ASDs were associated with altered cardiac dimensions already in the neonatal period, with larger right ventricular dimensions and larger atrial volumes at echocardiography within the first 30 days after birth.ClinicalTrials.gov Identifier: NCT02753348 (April 27, 2016).

A novel algorithm for classification of interatrial communications within the oval fossa in the newborn.

BACKGROUND: An interatrial communication is present in most neonates. The majority are considered the "normal" patency of the oval foramen, while a minority are abnormal atrial septal defects. Differentiation between the two with transthoracic echocardiography may be challenging, and no generally accepted method of classification is presently available. We aimed to develop and determine the reliability of a new classification of interatrial communications in newborns. METHODS AND RESULTS: An algorithm was developed based on echocardiographic criteria from 495 newborns (median age 11[8;13] days, 51.5% females). The algorithm defines three main categories: patency of the oval foramen, atrial septal defect, and no interatrial communication as well as several subtypes. We found an interatrial communication in 414 (83.6%) newborns. Of these, 386 (93.2%) were categorised as patency of the oval foramen and 28 (6.8%) as atrial septal defects.Echocardiograms from another 50 newborns (median age 11[8;13] days, 36.0% female), reviewed by eight experts in paediatric echocardiography, were used to assess the inter- and intraobserver variation of classification of interatrial communications into patency of the oval foramen and atrial septal defect, with and without the use of the algorithm. Review with the algorithm gave a substantial interobserver agreement (kappa = 0.66), and an almost perfect intraobserver agreement (kappa = 0.82). Without the use of the algorithm, the interobserver agreement between experienced paediatric cardiologists was low (kappa = 0.20). CONCLUSION: A new algorithm for echocardiographic classification of interatrial communications in newborns produced almost perfect intraobserver and substantial interobserver agreement. The algorithm may prove useful in both research and clinical practice.

A cross-sectional national study of burnout and psychosocial work environment in vascular surgery in Denmark.

OBJECTIVE: Little is known about burnout among European vascular surgeons (VSs). In this study, the prevalence of burnout and its associated risk factors were investigated among all VSs and vascular surgeons in training (VSTs) in Denmark. METHODS: An anonymous electronic survey was distributed to all clinical active VSs and VSTs on January 1, 2020. Validated assessment tools were used to measure burnout and aspects of the psychosocial work environment. RESULTS: A total of 104 VSs and VSTs were invited to participate, and 82% (n = 85) completed the survey. The majority of the respondents were male (60%; n = 50) and VSs (67%; n = 61). Of the respondents, 82% (n = 70) reported either light (54%; n = 46), moderate (22%; n = 19), or severe (6%; n = 5) personal burnout. More than 50% (n = 47) reported work-related burnout, light (39%; n = 33), moderate (9%; n = 8), and severe (7%; n = 6), respectively, whereas 35% (n = 30) reported patient-related burnout, light (31%; n = 26), moderate (2%; n = 2), and severe (2%; n = 2), respectively. Respondents with more than four 24-hour on-call shifts per month had significantly higher work-related burnout scores, whereas respondents with home-living children and those aged 45 to 59 years showed significantly higher personal and patient-related burnout, respectively. There were strong associations between personal and work-related burnout and the psychosocial work environment, especially work organization and interpersonal relations, but not job demands. The prevalence of burnout was unevenly distributed across departments, with the most affected department having a burnout occurrence twice the least affected department. CONCLUSIONS: Based on a national survey conducted among all clinical active VSs and VSTs in Denmark, more than 80% (n = 70) suffered from burnout, of whom 28% (n = 24) suffered from moderate to severe personal burnout. The strong association with the psychosocial work environment, and the significant differences between departments, suggest that burnout is modifiable through changes in the work environment.

The 'Quantal Newtonian' First Law: A Complementary Perspective to the Stationary-state Quantum Theory of Electrons.

A complementary perspective to the Göttingen-Copenhagen interpretation of stationary-state quantum theory of electrons in an electromagnetic field is described. The perspective, derived from Schrödinger-Pauli theory, is that of the individual electron via its equation of motion or 'Quantal Newtonian' First Law. The Law is in terms of 'classical' fields experienced by each electron: the sum of the external and internal fields vanishes. The external field is a sum of the electrostatic and Lorentz fields. The internal field is a sum of fields' representative of Pauli and Coulomb correlations; kinetic effects; electron density; and internal magnetic component. The energy is obtained from these fields. The sources of the fields are expectation values of Hermitian operators. The perspective is elucidated by application to quantum dots in a magnetic field in a ground, excited singlet and triplet states. The relationship of the perspective to Quantal and traditional density functional theories is briefly explained.

Heritability and Risk Factors of Incident Small and Large Drusen in the Copenhagen Twin Cohort Eye Study: A 20-Year Follow-Up.

INTRODUCTION: The transition from a normal fundus to one with early drusen (≥20 small hard drusen) to age-related macular degeneration (AMD) in the form of drusen ≥63 µm in diameter is of interest, because small hard drusen may be precursors of large drusen. Study of AMD precursor lesions may provide valuable insight into factors that initiate AMD. Here, the progression of drusen was studied over an interval of 20 years in a population-based twin cohort. METHODS: Single-center, 20-year follow-up of 138 twins include biometry, fundus optical coherence tomography, and fundus photography. Macular characteristics were hierarchically classified as (per eye) (1) <20 small hard drusen, (2) ≥20 small hard drusen, (3) drusen ≥63 µm, or (4) ≥20 small hard drusen combined with drusen ≥63 µm. Additive and dominant genetic effects as well as shared and nonshared environmental effects were analyzed in a bivariate biprobit model with a classic liability-threshold approach and polygenic modeling with random effects. RESULTS: Median participant age was 59 (range 41-66) years. Of 25 (18%) cases of incident macular drusen, 7 had ≥20 small hard drusen, and 18 had drusen ≥63 µm at follow-up, whereas no participant had developed both traits simultaneously. Smoking was associated with incident ≥20 small hard drusen (p = 0.04) and incident drusen ≥63 µm (p = 0.003). Having ≥20 small hard drusen at baseline was associated with incident drusen ≥63 µm at follow-up (p = 0.02). Development of drusen ≥63 µm was attributable to 49% genetic effects and 51% environmental effects. CONCLUSION: The risk of progressing from 0 to 19 small hard macular drusen per eye to having ≥20 small hard drusen or drusen ≥63 µm at follow-up was associated with smoking and genetic predisposition. Having ≥20 small hard drusen in the absence of drusen ≥63 µm at baseline was associated with incident drusen ≥63 µm when examined 20 years later. The study confirms that small hard macular drusen is a forewarning of AMD and that progression to AMD may be hindered by avoidance of smoking.

Prevalence of burnout syndrome among unmatched trainees and residents in surgical and nonsurgical specialties: a cross-sectional study from different training centers in Palestine.

BACKGROUND: Burnout is a psychological syndrome that involves physical, mental, and emotional exhaustion. This study was conducted to determine the prevalence of burnout among unmatched trainees and residents in surgical and nonsurgical specialties in Palestine. Additionally, this study also sought to identify the associated variables and predictors of higher burnout scores. METHODS: This study was conducted in a cross-sectional design using a questionnaire in the period between October 2020 and March 2021. The questionnaire collected sociodemographic characteristics of the residents and trainees in 18 different training centers/hospitals. The Copenhagen Burnout Inventory was used to determine burnout among the residents and trainees. Pearson's correlations, analysis of variance, Student's t-test, and multiple linear regressions were used to analyze the data. RESULTS: The study tool was completed by 250 residents and trainees in surgical and nonsurgical specialties (response rate = 83.3%). Of all participants, 203 (81.2%) reported a moderate-severe degree of burnout in the personal domain, 188 (75.2%) reported a moderate-severe degree of burnout in the work-related domain, and 97 (38.8%) reported moderate-severe degree of burnout in the client-related domain. There was a moderate and positive correlation between personal and work-related burnout scores (Pearson's r = 0.69, p-value < 0.001), and client-related burnout scores (Pearson's r = 0.52, p-value < 0.001). Similarly, there was a moderate and positive correlation between work-related and client-related burnout scores (Pearson's r = 0.57, p-value < 0.001). The multiple linear regression model showed that higher burnout scores were predicted by being married, not having another paid employment, inability to financially support oneself, frequent consumption of tea/coffee, dissatisfied with the training/job, thinking to change the profession, and long working hours. CONCLUSION: The findings of this study indicated that burnout was highly prevalent among residents and trainees in surgical and nonsurgical specialties in Palestine. Decision-makers in healthcare authorities, hospital managers, professional groups, directors of residency programs, and educators/trainers should consider addressing burnout and improving the well-being of residents and trainees in surgical and nonsurgical specialties in Palestine. Future studies are still needed to determine which interventions could be effective in reducing burnout among residents and trainees in surgical and nonsurgical specialties in Palestine.

The "unclear problem" category: an analysis of its patient and dispatch characteristics and its trend over time.

BACKGROUND: An effective emergency medical dispatch process is vital to provide appropriate prehospital care to patients. It increases patient safety and ensures the sustainable use of medical resources. Although Copenhagen has a sophisticated emergency medical services (EMS) system with a significant focus on public welfare, more than 10% of emergency cases are still being categorized as an "unclear problem category" (UPC) and are thus not categorized as "symptom-specific". Therefore, the objective of this research is to gain a better understanding of the patient and dispatch characteristics of emergency cases categorized as "unclear". METHODS: This register-based study based on medical emergency cases data describes patient and dispatch characteristics of emergency cases categorized as "unclear" through the use of numbers and proportions. Moreover, these cases were compared to non UPC cases. Use of UPC was stratified by month to determine the impact of alerting medical dispatchers to reduce its use. RESULTS: From 296,398 included cases UPC accounted for 11.4% of the cases. The median age of those triaged with the UPC was 66 years vs 58 years for individuals triaged with other symptom-specific categories. Moreover, after having been triaged with the UPC, 9,661 (34.7%) of the dispatched EMS vehicles ended up being cancelled. Sensitizing medical dispatchers about the use of the UPC likely contributed to the decreased use of the UPC over time. CONCLUSION: The UPC has different dispatch characteristics than the symptom-specific categories, with potential negative effects on the medical dispatch process. Moreover, the median age of individuals triaged with the UPC is higher than those triaged with symptom-specific categories. Nonetheless, the use of the UPC decreased throughout the study period after the medical dispatchers were alerted about the implications of its use.

Prevalence of burnout syndrome and its associated factors among doctors in Sabah, Malaysia.

Burnout syndrome is a condition marked by emotional exhaustion, deterioration in motivation and lack of commitment, resulting from long-lasting workplace stress, characterized by exhaustion, negative feelings towards one's work and reduced professional efficacy. Healthcare workers are at particularly high risk for burnout due to high levels of stress. Our objectives were to determine the prevalence of burnout syndrome among doctors in Sabah and factors associated with it. This multi-centre cross-sectional study was carried out among doctors working in five Sabah main hospitals. Data were collected by using self-administered questionnaires consisting of basic socio-demographic information and Copenhagen Burnout Inventory (CBI). Overall, a total of 523 doctors consented to participate in this study. The prevalence of personal burnout, work-related burnout, and patient-related burnout among doctors were 57.1%, 48.8%, and 30.4% respectively. Chi-square analysis showed factors that were associated to personal burnout and work-related burnout, were marital status, duration of service and position in the service. Duration of service was the only factor associated with patient-related burnout. The prevalence of burnout syndrome in Sabah should not to be overlooked and more researches are indicated to look into prevention of burnout syndrome in Malaysian setting.

Copenhagen Index versus ROMA in preoperative ovarian malignancy risk stratification: Result from the first Vietnamese prospective cohort study.

OBJECTIVES: This study aimed to evaluate the diagnostic performances of the Copenhagen Index (CPH-I) and Risk of Ovarian Malignancy Algorithm (ROMA) in the preoperative prediction of ovarian cancer. METHODS: In a prospective cohort study, data were collected from 475 patients with ovarian masses diagnosed by gynecologic examination / ultrasound who were hospitalized at the Departments of Obstetrics and Gynecology, Hue University of Medicine and Pharmacy Hospital and Hue Central Hospital, Vietnam, between January 2018 and June 2020. ROMA and CPH-I were calculated based on measurements of serum carbohydrate antigen (CA-125) and human epididymis protein (HE4). The final diagnosis was based on clinical features, radiologic and histologic findings, and the International Federation of Gynecology and Obstetrics (FIGO) 2014 stages of ovarian cancer were recorded. Matching the values of ROMA and CPH-I to postoperative histopathology reports resulted in the preoperative prediction values. RESULTS: Among the 475 women, 408 had benign tumors, 5 had borderline tumors and 62 had malignant tumors. The two indices showed similar discriminatory performances with no significant differences (p > 0.05). At an optimal cut-off, the sensitivities/specificities of ROMA and CPH-I for ovarian cancer diagnosis were 74.2% and 91.8%, 87.1% and 78.5%, respectively. The optimal cut-off for CPH-I was 1.89%. The areas under the ROC curves (AUCs) of ROMA and CPH-I were 0.882 (95% CI: 0.849-0.909) and 0.898 (95% CI: 0.867-0.924), respectively. CONCLUSIONS: The introduction of the Copenhagen Index to help stratify the malignancy risk of ovarian tumors, irrespective of menopausal status, might be applied as a simple alternative with a similar efficacy to ROMA in clinical practice.

The work of having a chronic condition: development and psychometric evaluation of the distribution of co-care activities (DoCCA) scale.

BACKGROUND: Chronic care involves multiple activities that can be performed by individuals and healthcare staff as well as by other actors and artifacts, such as eHealth services. Thus, chronic care management can be viewed as a system where the individual interacts with people and eHealth services performing activities to maintain or improve health and functioning, called co-care. Yet, the system perspective is not reflected in concepts such as person-centered care and shared decision making. This limits the understanding of individuals' global experience of chronic care management and subsequently the ability to optimize chronic care. The aim of this study was threefold: (1) to propose a theory-based operationalization of co-care for chronic care management, (2) to develop a scale to measure co-care as a distributed system of activities, and (3) to evaluate the scale's psychometric properties. With the theory of distributed cognition as a theoretical underpinning, co-care was operationalized along three dimensions: experience of activities, needs support, and goal orientation. METHODS: Informed by the literature on patient experiences and work psychology, a scale denoted Distribution of Co-Care Activities (DoCCA) was developed with the three conceptualized dimensions, the activities dimension consisting of three sub-factors: demands, unnecessary tasks, and role clarity. It was tested with 113 primary care patients with chronic conditions in Sweden at two time points. RESULTS: A confirmatory factor analysis showed support for a second-order model with the three conceptualized dimensions, with activities further divided into the three sub-factors. Cronbach's alpha values indicated a good to excellent reliability of the subscales, and correlations across time points with panel data indicated satisfactory test-retest reliability. Convergent, concurrent and predictive validity of the scale were, overall, satisfactory. CONCLUSIONS: The psychometric evaluation supports a model consisting of activities (demands, unnecessary tasks, and role clarity), needs support and goal orientation that can be reliably measured with the DoCCA scale. The scale provides a way to assess chronic care management as a system, considering the perspective of the individuals with the chronic condition and how they perceive the work that must be done, across situations, either by themselves or through healthcare, eHealth, or other means.

Burnout amongst neurosurgical trainees in the UK and Ireland.

INTRODUCTION: Burnout is becoming an increasingly recognised phenomenon within the medical profession. This study aims to investigate the presence of burnout amongst neurosurgical trainees in the UK and Ireland as well as investigating potential exacerbating and protective factors. METHOD: An online survey was sent to all neurosurgical trainees in the UK and Ireland via the British Neurosurgical Trainees' Association (BNTA) mailing list. Responding participants anonymously completed the Copenhagen Burnout Inventory (CBI) and answered questions about known risk factors for burnout including workplace environment, workplace bullying, time spent on leisure activities and sleep and reported likelihood of leaving neurosurgery. We also collated data on responders' demographics. We compared CBI scores for participants with and without risk factors to determine correlation with CBI. RESULTS: There were 75 respondents (response rate 42%) from a range of ages and all training grades, 72% of whom were male. The median CBI score was 38.85 (IQR 17.76). Participants showed a higher degree of personal and workplace burnout (median CBIs of 47.02, IQR 25.00; and 49.14, IQR 19.64, respectively) compared with patient-related burnout (median CBI 18.67, IQR 25.00). Participants with the following self-reported risk factors were significantly more likely to have higher CBIs: workplace bullying (p = 0.01), getting on less well with colleagues (p < 0.05), working longer hours (p < 0.05) and insufficient sleep, exercise and leisure time (all p < 0.01). Those with higher CBI scores were more likely to consider leaving neurosurgical training (p = 0.01). CONCLUSION: We identified a high burnout incidence in a cohort representative of UK neurosurgical trainees, although our results may have been skewed somewhat by selection bias. We determined potential risk factors for burnout related to specific workplace stressors and time for non-work activities. In the future, changes to training curricula should address these issues, aiming to improve training, enhance patient care and reduce attrition rates.
