Who becomes a dermatologist? A repeated cross-sectional study on diversity in the Dutch dermatology workforce
Background: Workforce diversity in dermatology is crucial for equitable, high-quality care, given the impact of skin tone, culture, and socio-economic status on skin conditions. Although this has been studied in other countries, data on the demographic makeup of Dutch dermatologists is lacking. This study aims to assess workforce diversity in Dutch dermatology over time. Methods: We conducted a nationwide repeated cross-sectional study using pseudonymized microdata from Statistics Netherlands, including sex, migration background, and parental socio-economic indicators. Descriptive statistics were used to track demographic trends between 2005 and 2023, and multivariable logistic regression analyses were performed to evaluate which variables influenced the odds that registered physicians in the 2023 national healthcare professional register (BIG register) had to be a dermatologist. Results: Female representation rose from 35.4% in 2005 to 61.7% in 2023. In 2023, 84.4% of dermatologists had no migration background or a European migration background. Dermatologists with Turkish, Moroccan, Surinamese, or Caribbean Dutch origins were underrepresented. Despite a net increase of 289 dermatologists, only 56 of this net increase consisted of dermatologists with a non-European background. Multivariable regression analysis showed that being female (OR 1.609 [1.143–2.266]), having parents in the top 20% assets bracket (OR 2.251 [1.272–3.984]), or having physician parents (OR 1.326 [1.011–1.740]) were associated with higher odds of being a registered dermatologist among the younger generation of physicians. Conclusions: The findings highlight a persistent lack of ethnic and socio-economic diversity in the Dutch dermatology workforce, despite broader demographic shifts in the general population and medical student cohorts. The underrepresentation of dermatologists with a migration background may have implications for equitable patient care, particularly in the context of cultural and linguistic barriers, as well as differences in disease presentation across skin tones. Further research is warranted to explore the potential impact of workforce diversity on patient outcomes.

Who gets to be a neurologist or neurosurgeon? Diversity and (in)equality in the Dutch medical sector
BackgroundA diverse physician workforce is essential for equitable healthcare, yet many specialties remain demographically unrepresentative. This study assessed (1) how well Dutch neurologists and neurosurgeons reflect national demographics by sex, migration background, and socioeconomic indicators; (2) changes in representation from 2005–2023; and (3) whether demographic characteristics are associated with practicing in these specialties. MethodsWe conducted repeated cross-sectional analyses using the Dutch BIG register (2005, 2010, 2015, 2020, 2023), including all registered neurologists and neurosurgeons. Variables included sex, migration background, parental BIG registration, and parental assets. Descriptive analyses assessed trends over time. Univariable and multivariable logistic regression examined associations between demographics and registration as a neurologist or neurosurgeon in 2023, in the full physician cohort and a younger subgroup born ≥1980. Results.In 2023, 1,233 neurologists and 190 neurosurgeons were registered. Women comprised 51.6% of neurologists and 16.8% of neurosurgeons. Non-European migration backgrounds were more prevalent in neurosurgery (22%) than neurology (10.5%). Across both specialties, ~20% had parents registered in the BIG register and >70% came from top-20% asset households. Non-European migration background was associated with lower odds of being a neurologist and high parental assets with higher odds, not observed in younger physicians. Neurosurgery was associated with male sex and higher parental assets; among younger neurosurgeons, male sex, non-European migration background, and sub-top asset status were associated with higher odds. ConclusionNeurology and neurosurgery in the Netherlands remain demographically unrepresentative, highlighting the need for transparent residency selection and systematic monitoring to promote equitable access.

Investigating the support for equitable admissions policies in health professions education: the Formal Consensus method
Higher education institutions increasingly aim to implement equity in admissions. However, there is no one-size-fits-all solution to determine which equitable admissions procedures are suitable in a specific context, nor which groups should be its beneficiaries. Therefore, we applied the Formal Consensus Method (FCM) to investigate the support amongst experts and stakeholders for different equitable admissions policies and target groups within the context of Health Professions Education in The Netherlands. We found majority support (median of ratings ≥ 7 on a scale of 1 to 9) in both groups for the target groups ‘applicants with a low or average socio-economic status’ and ‘applicants with an underrepresented migration background’. The majority of participants was also in favor of Contextualized Admissions, especially when used to increase enrolment of applicants with a low or average socio-economic status, with an underrepresented migration background, and asylum status holders. Lastly, both groups supported lottery with extra tickets for applicants with an underrepresented migration background. However, as the range of ratings fell outside the FCM prescribed range of 5-9, no case in which there was majority support could be defined as a ‘consensus’. The expert group proposed the use of Bonded Medical Places for applicants from the Caribbean parts of the Dutch Kingdom. The policies and target groups for which broad support was found, could contribute to equitable admissions, improved student diversity, and enhanced quality of health education and future care. Our application of the FCM in the area of equitable admissions policies may be useful for researchers in other countries where equity principles are not (widely) used in admissions decisions.

Inequality of opportunity in selection procedures limits diversity in higher education: An intersectional study of Dutch selective higher education programs
Selection for higher education (HE) programs may hinder equal opportunities for applicants and thereby reduce student diversity and representativeness. However, variables which could play a role in inequality of opportunity are often studied separately from each other. Therefore, this retrospective cohort study conducts an innovative intersectional analysis of the inequality of opportunity in admissions to selective HE programs. Using a combination of multivariable logistic regression analyses and descriptive statistics, we aimed to investigate 1) the representativeness of student populations of selective HE programs, as compared to both the applicant pool and the demographics of the age cohort; 2) the demographic background variables which are associated with an applicant’s odds of admission; and 3) the intersectional acceptance rates of applicants with all, some or none of the background characteristics positively associated with odds of admission. The study focused on all selective HE programs (n = 96) in The Netherlands in 2019 and 2020, using Studielink applicant data (N = 85,839) and Statistics Netherlands microdata of ten background characteristics. The results show that student diversity in selective HE programs is limited, partly due to the widespread inequality of opportunity in the selection procedures, and partly due to self-selection. Out of all ten variables, migration background was most often (negatively) associated with the odds of receiving an offer of admission. The intersectional analyses provide detailed insight into how (dis)advantage has different effects for different groups. We therefore recommend the implementation of equitable admissions procedures which take intersectionality into account.

Influence of social networks in healthcare on preparation for selection procedures of health professions education: a Dutch interview study
Objectives Health professions education (HPE) students are often not representative of the populations they will serve. The underrepresentation of non-traditional students is problematic because diversity is essential for promoting excellence in health education and care. This study aimed to understand the perceptions of traditional and non-traditional students regarding facilitators and barriers in preparing for HPE selection procedures, and to determine the role of social networks in their decision-making and preparations to apply. Methods A qualitative study was conducted with 26 Dutch youth who were interested in university-level HPE programmes. Semistructured interviews and sociograms were analysed using thematic analysis, adopting a constructivist approach. Results Twenty-six high school students participated, with traditional and non-traditional backgrounds, with and without social networks in healthcare and higher education. Two themes were constructed. First, four high-impact facilitators helped to overcome barriers to apply and in preparation for selection: access to a social network connection working or studying in healthcare, to correct information, to healthcare experience and to a social network connection in higher education. Lack of information was the main barrier while access to social network connections in healthcare was the main facilitator to overcome this barrier. However, this access was unevenly distributed. Second, access alone is not enough: the need for agency to make use of available facilitators is also essential. Conclusions The themes are discussed using intersectionality. Traditional students with access to facilitators develop their self-efficacy and agency within social structures that privilege them, whereas non-traditional students must develop those skills without such structures. Our findings provide recommendations for the ways in which universities can remove barriers that cause unequal opportunities to prepare for the selection of HPE programmes. Along with equitable admissions, these recommendations can help to achieve a more representative student population and subsequently a better quality of health education and care.
