Admission criteria and diversity in medical school.

CONTEXT: The under-representation in medical education of students from lower socio-economic backgrounds is an important social issue. There is currently little evidence about whether changes in admission strategies might increase the diversity of the medical student population. Denmark introduced an 'attribute-based' admission track to make it easier for students who may not be eligible for admission on the 'grade-based' track to be admitted on the basis of attributes other than academic performance. The aim of this research was to examine whether there were significant differences in the social composition of student cohorts admitted via each of the two tracks during the years 2002-2007. METHODS: This prospective cohort study included 1074 medical students admitted during 2002-2007 to the University of Southern Denmark medical school. Of these, 454 were admitted by grade-based selection and 620 were selected on attributes other than grades. To explore the social mix of candidates admitted on each of the two tracks, respectively, we obtained information on social indices associated with educational attainment in Denmark (ethnic origin, father's education, mother's education, parenthood, parents living together, parent in receipt of social benefits). RESULTS: Selection strategy (grade-based or attribute-based) had no statistically significant effect on the social diversity of the medical student population. CONCLUSIONS: The choice of admission criteria may not be very important to widening access and increasing social diversity in medical schools. Attracting a sufficiently diverse applicant pool may represent a better strategy for increasing diversity in the student population.

[Admission tests for medical education]. / Optagelsesprøver på medicinstudiet.

This state of the art article explores what is known from the international and Danish literature on admission criteria as predictors of success in medical education. Previous academic performance is the best known predictor of medical students' grades. Poorer entry qualifications, broadly defined, are associated with dropout in medical education. Admission interviews may have a small additive explanatory effect on medical students' grades, but the effect on dropout has barely been investigated. Admission interviews are a challenge for the feasibility, reliability and validity of medical student selection. Admission variables in use should be supported by predictive validity.

Medical school dropout--testing at admission versus selection by highest grades as predictors.

CONTEXT: Very few studies have reported on the effect of admission tests on medical school dropout. The main aim of this study was to evaluate the predictive validity of non-grade-based admission testing versus grade-based admission relative to subsequent dropout. METHODS: This prospective cohort study followed six cohorts of medical students admitted to the medical school at the University of Southern Denmark during 2002-2007 (n=1544). Half of the students were admitted based on their prior achievement of highest grades (Strategy 1) and the other half took a composite non-grade-based admission test (Strategy 2). Educational as well as social predictor variables (doctor-parent, origin, parenthood, parents living together, parent on benefit, university-educated parents) were also examined. The outcome of interest was students' dropout status at 2 years after admission. Multivariate logistic regression analysis was used to model dropout. RESULTS: Strategy 2 (admission test) students had a lower relative risk for dropping out of medical school within 2 years of admission (odds ratio 0.56, 95% confidence interval 0.39-0.80). Only the admission strategy, the type of qualifying examination and the priority given to the programme on the national application forms contributed significantly to the dropout model. Social variables did not predict dropout and neither did Strategy 2 admission test scores. CONCLUSIONS: Selection by admission testing appeared to have an independent, protective effect on dropout in this setting.

Factors associated with dropout in medical education: a literature review.

CONTEXT: Medical school dropout may have negative consequences for society, patients, the profession, schools and dropouts. To our knowledge, the literature dealing with dropout from medical school has never been systematically and critically appraised. OBJECTIVES: This review aimed to systematically and critically review studies dealing with factors found to be associated with dropping out of medical school. METHODS: A systematic critical literature review of the international peer-reviewed research literature on medical education was performed. A primary search was conducted and subsequently supplemented with ancestry and descendancy searches. The population of interest was medical students and the outcome was dropout. Abstract/title screening and quality assessment were performed by two independent researchers. Studies were assessed on six domains of quality: study participation; study attrition; predictor measurement; measurement of and accounting for confounders; outcome measurement, and analysis. Only studies that accounted for confounding were included in the final analysis. RESULTS: Of 625 studies found, 48 were quality-assessed and 13 of these were eventually included based on their fulfilment of our quality-related criteria. A range of entry qualifications seemed to be associated with greater chances of a student dropping out (odds ratio [OR] = 1.65-4.00). Struggling academically in medical school may be strongly associated with dropout. By contrast, no specific pattern of demographic variables was particularly important in relation to dropout. The effects of socio-economic, psychological and educational variables on dropout were not well investigated. CONCLUSIONS: More research into causal models and theory testing, which considers the effects of education, organisation and institution, is necessary if we are to learn more about how we can actively prevent medical student withdrawal.

Teaching acid/base physiology in the laboratory.

Acid/base homeostasis is one of the most difficult subdisciplines of physiology for medical students to master. A different approach, where theory and practice are linked, might help students develop a deeper understanding of acid/base homeostasis. We therefore set out to develop a laboratory exercise in acid/base physiology that would provide students with unambiguous and reproducible data that clearly would illustrate the theory in practice. The laboratory exercise was developed to include both metabolic acidosis and respiratory alkalosis. Data were collected from 56 groups of medical students that had participated in this laboratory exercise. The acquired data showed very consistent and solid findings after the development of both metabolic acidosis and respiratory alkalosis. All results were consistent with the appropriate diagnosis of the acid/base disorder. Not one single group failed to obtain data that were compatible with the diagnosis; it was only the degree of acidosis/alkalosis and compensation that varied.

Generalizability of a composite student selection procedure at a university-based chiropractic program.

PURPOSE: Non-cognitive admission criteria are typically used in chiropractic student selection to supplement grades. The reliability of non-cognitive student admission criteria in chiropractic education has not previously been examined. In addition, very few studies have examined the overall test generalizability of composites of non-cognitive admission variables in admission to health science programs. The aim of this study was to estimate the generalizability of a composite selection to a chiropractic program, consisting of: application form information, a written motivational essay, a common knowledge test, and an admission interview. METHODS: Data from 105 Chiropractic applicants from the 2007 admission at the University of Southern Denmark were available for analysis. Each admission parameter was double scored using two random, blinded, and independent raters. Variance components for applicant, rater and residual effects were estimated for a mixed model with the restricted maximum likelihood method. The reliability of obtained applicant ranks (generalizability coefficients) was calculated for the individual admission criteria and for the composite admission procedure. RESULTS: Very good generalizability was found for the common knowledge test (G=1.00) and the admission interview (G=0.88). Good generalizability was found for application form information (G=0.75) and moderate generalizability (G=0.50) for the written motivation essay. The generalizability of the final composite admission procedure, which was a weighted composite of all 4 admission variables was good (G(c) = 0.80). CONCLUSION: Good generalizability for a composite admission to a chiropractic program was found. Optimal weighting and adequate sampling are important for obtaining optimal generalizability. Limitations and suggestions for future research are discussed.

Generalisability of a composite student selection programme.

UNLABELLED: OBJECTIVES The reliability of individual non-cognitive admission criteria in medical education is controversial. Nonetheless, non-cognitive admission criteria appear to be widely used in selection to medicine to supplement the grades of qualifying examinations. However, very few studies have examined the overall test generalisability of composites of non-cognitive admission variables in medical education. We examined the generalisability of a composite process for selection to medicine, consisting of four variables: qualifications (application form information); written motivation (in essay format); general knowledge (multiple-choice test), and a semi-structured admission interview. The aim of this study was to estimate the generalisability of a composite selection. METHODS: Data from 307 applicants who participated in the admission to medicine in 2007 were available for analysis. Each admission parameter was double-scored using two random, blinded and independent raters. Variance components for applicant, rater and residual effects were estimated for a mixed model with the restricted maximum likelihood (REML) method. The reliability of obtained applicant ranks (G coefficients) was calculated for individual admission criteria and for composite admission procedures. RESULTS: A pre-selection procedure combining qualification and motivation scores showed insufficient generalisability (G = 0.45). The written motivation in particular, displayed low generalisability (G = 0.10). Good generalisability was found for the admission interview (G = 0.86), and for the final composite selection procedure (G = 0.82). CONCLUSIONS: This study revealed good generalisability of a composite selection, but indicated that the application, composition and weighting of individual admission variables should not be random. Knowledge of variance components and generalisability of individual admission variables permits evidence-based decisions on optimal selection strategies.
