Utility of a writing station in the multiple mini-interview.

The multiple mini-interview (MMI) is a reliable and valid method of selecting applicants for admission to health professional schools on the basis of non-cognitive traits. Because the MMI is a series of short interview stations that applicants rotate through in coordinated sequence, it can potentially be resource intensive. However, the MMI design has room for innovation and efficiency. At the University of Manitoba Faculty of Medicine, a 10-minute unsupervised writing station (WS) was incorporated into the MMI to obtain a writing sample from each applicant, to increase the number of independent scores per applicant, and to increase the number of applicants interviewed per circuit without increasing interviewer numbers. One assessor evaluated all the writing samples and assigned a score ranging from 1 to 7. With the inclusion of a WS into an 11-station MMI, the faculty's capacity to interview applicants increased by 9% (from 297 to 324) without substantially increasing interviewer hours needed per day. For 1,257 applicants interviewed in 2008-2011, the mean WS score was 4.03 (SD=1.36), whereas applicants' mean of 10 oral station (OS) scores was 4.62 (SD=0.69). Correlations between WS score and mean OS score ranged from .16 to .27 (p<.01) over the four years. Because inter-station correlations for OS ranged from .01 to .37, the correlation of .21 between WS and mean OS scores for all four years combined appears reasonable. Institutions that want to effectively increase the capacity of their MMI process might consider adding a WS.

Multiple mini-interview scores of medical school applicants with and without rural attributes.

INTRODUCTION: Students from rural areas are under-represented in medical schools. Concerns have been raised about rural applicants' qualifications relative to those of their urban counterparts, and the impact such potential differences in competitiveness may have on their under-representation. Although studies have reported no differences in Grade Point Average (GPA) and Medical College Admission Test (MCAT) scores between applicants with and without rural attributes, to date no study has assessed if performance on the multiple mini-interview (MMI) varies between the two groups. METHODS: The MMI scores of 1257 interviewees for admission to the MD program at the Faculty of Medicine, University of Manitoba, in years 2008 to 2011, were studied for an association with graduation from a rural high school and attributes in the following three domains: rural connections, employment in rural areas, and rural community service. RESULTS: There were 205 (16.3%) rural high school graduates among interviewed applicants. Rural high school graduates scored significantly lower (mean of 4.4 on a scale of 1 to 7; p < 0.05) than urban high school graduates (4.6). Among rural-attribute domains, those with rural community service alone had the highest MMI scores (4.9) while those with rural connections alone had the lowest scores (4.3; p = 0.016). After adjusting for demographics, GPA, and MCAT scores in a multiple linear regression model, rural-attribute domains were not significant predictors of an applicant's MMI score. However, graduation from a rural high school was significantly associated with decreased MMI scores (a 0.122 decrease in predicted MMI scores on a scale of 1 to 7). CONCLUSION: Despite graduates from rural and urban high schools having comparable GPA, there exists a rural-urban divide in MMI scores that could exacerbate the under-representation of rural students in medical schools. Aboriginal applicants can also potentially be disproportionately affected, as they were more often from rural high schools than from urban high schools. Future studies need to determine systematic and institutional reasons, if any, for the differential in MMI scoring that can affect admission decisions for some rural applicants. It is also to be noted that the magnitude of difference is small enough that it may ultimately be irrelevant for future physician performance and practitioner outcomes.

Use of Z-scores to rank applicants to professional degree programs.

Criteria for assessing suitability of applicants for professional degree programs such as veterinary medicine are usually treated as distinct components of a composite scoring procedure that determines applicant ranking. Some components are valued more than others, which is reflected in the relative weights assigned to each component. However, the patterns of dispersal of individual components have the potential to alter the assigned relative weights. Components with larger variances can have greater influences on composite scores than intended. Such unintended altered weighting can be avoided through standardization. Yet non-standardized approaches continue to be used for admissions ranking in several programs. In this study, we documented the potential for differential selection of applicants when non-standardized scoring approaches are applied to admissions assessment components. At our medical school, applicants' component scores with differing variances are standardized by determining Z-scores with a mean of 0 and standard deviation of 1 before mathematically combining to calculate composite scores and admissions ranking. We retrospectively and hypothetically ranked one applicant cohort using non-standardized methods and identified differences in ranking between the standardized and non-standardized approaches. Most differences were observed for applicants in the second, third, and fourth quintiles of the admissions rank list, that is, those for whom admissions cut-off decisions make a marked difference. Observations were supported by lower Spearman's rank correlation coefficients in these quintiles. Although standardization of component scores is not a novel topic, we document the implications of using non-standardized scoring approaches for applicant ranking and underscore the importance of standardization of component scores.

Functional gene polymorphisms in canadian aboriginal populations with high rates of tuberculosis.

The present study determined whether a pattern of functional single-nucleotide polymorphisms (SNPs) was present that could predispose a Dené cohort to a suboptimal response to Mycobacterium tuberculosis. Compared with a Caucasian cohort, the Dené and Cree were found to maintain a significantly higher frequency of SNPs associated with low expression of vitamin D receptor (VDR), interferon (IFN)-gamma (+874), and tumor necrosis factor-alpha (-308) and high production of monocyte chemoattractant protein (MCP)-1 (-2518) and interleukin (IL)-6 (-174). Given the roles played by IFN-gamma and VDR in facilitating macrophage containment of M. tuberculosis and the opposing role of MCP-1 and IL-6, the observed allelic variation by ethnicity may in part contribute to the high rates of tuberculosis among the Dené.

Diabetic foot complications in a northern Canadian Aboriginal community.

BACKGROUND: Limited access to basic foot care and protective footwear may contribute to diabetic foot complications. The purpose of this study was to determine the prevalence of foot complications, ongoing foot care, and footwear use in diabetic subjects in a remote northern Canadian Aboriginal community. METHODS: This was a cross-sectional cohort study of 169 diabetic people, including interview, physical examination, and retrospective chart review. RESULTS: The mean age of the 169 diabetic individuals in the study was 56 +/- 12 years and their duration of diabetes 10 +/- 7 years. There were 139 (82%) individuals who had 418 diabetic foot complications (average, 3.0 complications per subject with complications), including toenail pathology, foot and ankle deformities, calluses, impaired pulses, neuropathy, past or present ulcer, amputation, and Charcot arthropathy. Risk classification showed that 69 (41%) individuals were at risk for future ulceration. Fifty-five (33%) individuals had inadequate footwear for their foot risk category, and only 11 (17%) of 66 individuals in the higher risk categories (categories 2 and 3) had suitable footwear. In a 7-year period, only 0.7 screening foot examinations per diabetic subject per year were documented. However, during this period, foot problems accounted for 498 (18%) local emergency room visits, 359 (16%) hospitalization days, 109 (11%) nonemergency transfers, and 4 (6%) emergency transfers to a tertiary care hospital. CONCLUSIONS: Foot and ankle complications of diabetes in this remote Aboriginal community were common and associated with substantial morbidity. Preventive diabetic foot screening examinations and footwear were inadequate. The results suggest that programs for prevention and early detection of complications are needed, including foot screening, provision of appropriate footwear, and foot care.

Disability and quality of life in Canadian aboriginal and non-aboriginal diabetic lower-extremity amputees.

OBJECTIVE: To compare and contrast disability and quality of life (QOL) in Aboriginal and non-Aboriginal subjects with diabetes who had lower-extremity amputation (LEA) and were living in urban and rural communities in Canada. DESIGN: Descriptive study using an interviewer-administered questionnaire and hospital medical record review. SETTING: Tertiary care center. PARTICIPANTS: Forty-four diabetic subjects (minimum age, 18 y) not receiving dialysis, including 21 Aboriginal (8 urban, 13 rural) and 23 non-Aboriginal (16 urban, 7 rural) subjects. Subjects were living in their current residence and had undergone LEA above the level of the ankle 6 months or more before interview. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Qualitative and quantitative data about symptoms, impairment, and QOL. RESULTS: Aboriginal subjects were younger than non-Aboriginal subjects at the time of diabetes diagnosis (Aboriginal, 42+/-10 y; non-Aboriginal, 52+/-14 y; P<.005) and first major LEA (Aboriginal, 57+/-7 y; non-Aboriginal, 64+/-11 y; P<.015). All subjects received rehabilitation after amputation. More rural non-Aboriginal subjects (83%) used their prosthesis both in and outside the home for all movements than other subjects (P<.048). Rural non-Aboriginal subjects had the lowest and urban non-Aboriginal subjects had the highest frequency of walking-aid use outside the home. Assistance with personal care was required by a minority of subjects, but assistance with daily housework was required by the majority of subjects. Qualitative analysis revealed that participants were, in most cases, comfortable with their postamputation life. CONCLUSIONS: Although the majority of participants in this study generally felt satisfied with their current status, major functional changes were noted after LEA that had a large negative impact on QOL.

Understanding death and dying in select first nations communities in northern Manitoba: issues of culture and remote service delivery in palliative care.

OBJECTIVES: The purpose of this study was to delineate and describe the local palliative care services available to residents of remote Aboriginal communities in northern Manitoba; to identify attitudes and beliefs about death, dying and palliative care in these communities; and to explore obstacles related to palliative care service delivery from the perspectives of culture and geographic isolation. STUDY DESIGN: Forty-four in-depth semi-structured interviews were conducted with a reputational sample of key informants including Aboriginal people resident in remote communities, community elders and religious leaders, doctors, nurses and allied health care providers working in First Nations Communities, as well as specialist service providers in Winnipeg. Thematic qualitative analysis was done on the data collected. Data collected from interviews with northern physicians and nurses was coded and analyzed. RESULTS: Currently, many Aboriginal people living in remote communities are transported to large urban centers to die, isolated from friends, family and their culture. However, the majority of Aboriginal people and health care providers interviewed reported that Aboriginal people living in remote communities would prefer to die at home. The issues surrounding palliative care provision in remote Aboriginal communities are cultural and geographic. Culturally sensitive care requires that patients have access to family supports and traditional services if requested. Geographic isolation requires that: 1. patient-specific care plans be created for use in the remote community; 2. effective lines of communication are established between remote health care providers and urban specialists; 3. health care providers and family care-givers be properly trained to fill their respective roles; and 4. appropriate guidelines and resources be available in the community to support this type of care. CONCLUSIONS: Providing the equipment, supports and education necessary for home-based palliative care in remote Aboriginal communities can be an effective way of addressing the medical, psycho-social, and spiritual needs of these patients.
