How we designed and implemented teaching, training, and assessment of professional behaviour at VUmc School of Medical Sciences Amsterdam

Background: Training of doctors in The Netherlands seeks to develop clinical competences including professional behaviour. Behaving as a professional is not just a desirable trait but a clearly stated requirement for doctors and medical students. Results: We designed an educational theme, Professional Behaviour (PB), as a longitudinal thread throughout our six-year curriculum after defining PB as “The observable aspects of practising professionalism”. This definition was translated into a set of practical skills that can be observed: “The ability to deal with tasks, to deal with others and to deal with oneself”. We assess PB 29 times in the course of the medical curriculum. Students with an unsatisfactory PB do not get their degree irrespective of their medical knowledge. We train teachers to identify and report unprofessional student behaviour, and we offer these students interventions and support. Conclusions: With the educational theme “Professional Behaviour” we have defined PB for our institute and firmly embedded it in the medical curriculum. We use workplace learning and role models for teaching PB. Different teachers carry out multiple formative and summative assessments, using standardized assessment scales. With these measures we intend to promote a culture of excellence in PB in our institute.

Changes in cerebral glycolytic activity during transport of critically ill neurotrauma patients measured with microdialysis

Abstract. Critically ill ventilated head injured patients often undergo in-hospital transports for diagnostic purposes. This transport is associated with an increased rate of complications. Secondary adverse events can occur, even in optimal conditions. We describe four patients in whom continuous cerebral microdialysis was performed during transportation to and from the CT Department. An increase in lactate/pyruvate ratio, glucose concentration and glutamate concentration was found, suggesting increased metabolic demand and relative or absolute impaired oxygen delivery. This occurred whilst all other measures, which are normally considered optimal for monitoring oxygen saturation and hemodynamics, showed no significant changes.

Knowledge and beliefs about epilepsy among people with and without epilepsy in urban Suriname

Reducing the burden of epilepsy in low- and middle-income countries requires understanding of the cultural aspects of epilepsy. This cross-sectional study among individuals attending a clinic in an urban setting in Paramaribo, Suriname aimed to obtain information on the knowledge of and attitudes towards epilepsy and epilepsy treatment, comparing people with epilepsy (PWE) to those without epilepsy. This study also explored the help-seeking behavior and experience of having epilepsy in PWE. While the results of interviews with 49 PWE and 33 controls compared favorably to studies conducted in similar countries, a significant minority of PWE still rely on traditional remedies. Prejudices regarding social roles, schooling, and occupational choices of PWE also remain prevalent. Currently, the major source of information for both groups is the media, but there could be opportunities for the local epilepsy association to play a larger role. These findings, despite some selection bias, could be useful in bringing conventional medical treatment strategies to more PWE in Suriname, as well as empower patient organizations in designing stigma-reducing interventions.

Distinguishing Three Unprofessional Behavior Profiles of Medical Students Using Latent Class Analysis

Purpose Because unprofessional behavior of physicians is associated with unprofessional behavior in medical school, identifying unprofessional behavior in medical school is critical. Research has noted the difficulty in assessing professional behavior. Instead of identifying isolated behaviors, it could be more helpful to recognize behavioral patterns to evaluate students’ professional behavior. The authors aimed to identify patterns in the unprofessional behaviors of medical students and to construct descriptions based on these patterns. Method Content analysis of research articles yielded a template of unprofessional behaviors for coding student evaluation forms indicating unsatisfactory professional behavior, collected from 2012 to 2014 at the VUmc School of Medical Sciences, Amsterdam, the Netherlands. Latent class analysis was used to identify classes of students with a high chance of displaying comparable unprofessional behaviors. Teachers’ feedback of prototype students was summarized to generate profile descriptions. Results A template of 109 behaviors was used to code 232 evaluation forms of 194 students (3.9% students/year). Latent class analysis identified three hypothetical classes of students: Class 1 (43%) was labeled as “Poor reliability,” class 2 (20%) was labeled as “Poor reliability and poor insight,” and class 3 (37%) was labeled as “Poor reliability, poor insight, and poor adaptability.” Conclusions These profiles of unprofessional behavior might help to improve the evaluation of unprofessional behavior in medical school. Further research should provide evidence for confidently accepting or rejecting the profiles as an instrument to identify which students are expected to benefit from remediation trajectories.

Incidence and Treatment of Central Nervous System Tumors in Suriname

OBJECTIVE To estimate the incidence of central nervous system (CNS) tumors in Suriname. METHODS A retrospective chart review was performed at the Academic Hospital Paramaribo and the State Health Insurance foundation. Patients receiving a diagnosis of CNS tumor in the period 2000-2010 were included in the study if a computed tomography scan or magnetic resonance imaging study was available. Demographic data and patient characteristics and disease variables were retrieved. RESULTS The study comprised 251 patients who met the inclusion criteria. The incidence of treated CNS tumors was 5 per 100,000 per year. There was a peak incidence in the 41-50 age group and a male-to-female ratio of 1:1.46. Of CNS tumors, 21% were gliomas, 26.7% were meningiomas, 4.7% were schwannomas, and 12.0% were pituitary adenomas. Suriname has a low glioma incidence compared with globally (40%-60% of CNS tumors globally). The incidence of pituitary adenoma was higher than expected. There are indications for a higher glioma and meningioma incidence in Javanese and a higher metastases incidence in Creoles. CONCLUSIONS The annual incidence of treated CNS tumors of 5 per 100,000 inhabitants in Suriname was in accordance with the expectation of an incidence of 3-6 per 100,000. Suriname is considered a country with a low cancer incidence. The differences found among various subgroups were too small to make definitive statements.

Behavior and attitudes among European neurosurgeons – An international survey

BACKGROUND A recent survey showed that potentially hazardous levels of certain attitudes have been associated with worse patient outcomes in orthopedic surgery, based on a questionnaire that was adopted from aviation. This questionnaire aims to evaluate the prevalence of potentially hazardous levels of machismo, impulsiveness, anxiety, antiauthority, resignation, and invulnerability in attitudes and was adopted for use among neurosurgeons. METHODS All individual members of the European Association of Neurosurgical Societies (EANS) were invited to fill-out an online questionnaire. Questions were on a five-point Likert-scale ranging from strongly disagree to strongly agree with five questions per attitude and answers were collected together with neurosurgeon and practice characteristics. Participants could score five points for each question after which an overall score was calculated for each attitude. Like the orthopedic survey, a potentially hazardous level of any behavior was defined as a score >20. RESULTS Resignation (n = 21; 7.7%) and anxiety (n = 10; 3.7%) had the highest prevalence of potentially hazardous levels among neurosurgeons. Few neurosurgeons showed potentially hazardous levels of antiauthority (n = 4; 1.5%), self-confidence (n = 2; 0.7%), or impulsive attitudes (n = 1; 0.4%). None of the participants showed potentially hazardous levels of machismo. Overall, 12.2% of neurosurgeons had a potentially hazardous score for at least one of the evaluated attitudes. CONCLUSION Findings of this study indicate a low prevalence of potentially hazardous levels of certain attitudes among neurosurgeons based on a questionnaire tailored to neurosurgery. However, the implications of this study are limited by various factors and warrant further evaluation and warrant further evaluation.

Exploring the situational motivation of medical specialists: a qualitative study

Objectives The aim was to obtain insight into the factors in the work environment that motivate or demotivate a medical specialist during his/her working day. Methods A qualitative ethnographic design was used, and a constructivist approach was adopted with the Self-Determination theory of motivation as a framework. Six medical specialists from VU University Medical Center in the Netherlands, recruited through convenience, snowball, and purposive sampling, were shadowed for one day each. Data were transcribed and open-coded. Themes were finalized through discussion and consensus. Results Sixty hours of observation data identified motivating and demotivating factors categorized into four themes that are important for specialists’ motivation. Informational technology issues are demotivating factors. Working with colleagues can be both a motivating and demotivating factor, e.g., filling in for each other through feelings of relatedness was motivating. Being in control of one’s planning through feelings of autonomy was motivating. Furthermore, patient care and teaching, especially in combination, stimulated specialists’ motivation. Regarding the design of the study, we found that situational motivation is indeed observable. Conclusions The basic psychological needs autonomy, competence, and relatedness are important for specialists’ motivation. Investing in a more motivating, open, transparent, and basic-needs- supportive work environment for medical specialists is necessary. Keywords: Continuing professional development, motivation, medical specialists, self-determination theory, qualitative research.

The occurrence of benign brain tumours in transgender individuals during cross-sex hormone treatment

Benign brain tumours may be hormone sensitive. To induce physical characteristics of the desired gender, transgender individuals often receive cross-sex hormone treatment, sometimes in higher doses than hypogonadal individuals. To date, long-term (side) effects of cross-sex hormone treatment are largely unknown. In the present retrospective chart study we aimed to compare the incidence of common benign brain tumours: meningiomas, pituitary adenomas (non-secretive and secretive), and vestibular schwannomas in transgender individuals receiving cross-sex hormone treatment, with those reported in general Dutch or European populations. This study was performed at the VU University Medical Centre in the Netherlands and consisted of 2555 transwomen (median age at start of cross-sex hormone treatment: 31 years, interquartile range 23-41) and 1373 transmen (median age 23 years, interquartile range 18-31) who were followed for 23 935 and 11 212 person-years, respectively. For each separate brain tumour, standardized incidence ratios with 95% confidence intervals were calculated. In transwomen (male sex assigned at birth, female gender identity), eight meningiomas, one non-secretive pituitary adenoma, nine prolactinomas, and two vestibular schwannomas occurred. The incidence of meningiomas was higher in transwomen than in a general European female population (standardized incidence ratio 4.1, 95% confidence interval 1.9-7.7) and male population (11.9, 5.5-22.7). Similar to meningiomas, prolactinomas occurred more often in transwomen compared to general Dutch females (4.3, 2.1-7.9) and males (26.5, 12.9-48.6). Noteworthy, most transwomen had received orchiectomy but still used the progestogenic anti-androgen cyproterone acetate at time of diagnosis. In transmen (female sex assigned at birth, male gender identity), two cases of somatotrophinomas were observed, which was higher than expected based on the reported incidence rate in a general European population (incidence rate females = incidence rate males; standardized incidence ratio 22.2, 3.7-73.4). Based on our results we conclude that cross-sex hormone treatment is associated with a higher risk of meningiomas and prolactinomas in transwomen, which may be linked to cyproterone acetate usage, and somatotrophinomas in transmen. Because these conditions are quite rare, performing regular screenings for such tumours (e.g. regular prolactin measurements for identifying prolactinomas) seems not necessary.
