The alignment imperative in curriculum renewal

Abstract

Rationale: There are perennial calls for MD curricula to reform in order to meet the changing needs of students, patients, and society. And yet, efforts at renewal have also been suggested to have minimal impact on the pedagogy and outcomes of medical education. One reason may be misalignment between the components of the curriculum during design and implementation. The University of Toronto MD program recently renewed its undergraduate preclinical Foundations curriculum. Mindful of the pitfalls of misalignment, the renewal process focused deliberately on alignment between the various components of the curriculum: instructional methods, student assessment, faculty development, and the larger purpose of serving students and society.

Innovation: Educational evidence was used to drive the alignment process which resulted in three major changes. First, we created a spiral curriculum centered on 72 virtual patient cases designed to integrate content and prepare students for clinical learning. Second, we introduced a novel medical psychiatry component to address a core societal need in mental health. This exposed students early to experiences of complexity, ambiguity, and integrated patient care. Lastly, a shift to assessment for learning and programmatic assessment was designed and implemented concurrently to reinforce the pedagogy of the curriculum. Synchronous faculty development was developed for the new roles required of faculty.

Conclusions: Early program evaluation shows alignment of these curricular components requires ongoing attention and resources in order to be successful. The potential benefits of this alignment are well prepared students who can meet the needs of their patients and society in an increasingly complex health system.     

The effect of conceptual and contextual familiarity on transfer performance

Applying a previously learned concept to a novel problem is an important but difficult process called transfer. It is suggested that a commonsense analogy aids in transfer by linking novel concepts to familiar ones. How the context of practice affects transfer when learning using analogies is still unclear. This study investigated the effect of a commonsense analogy and context familiarity for transfer of physiological concepts. First year psychology students (n = 24) learned three concepts: Starling's law, Laplace's law, and laminar-turbulent flow. The control group saw standard explanations while the intervention group saw an additional commonsense analogy. The context of learning was the organ system used for two practice clinical cases which differed for all concepts. Testing consisted of 12 new clinical cases. Starling's law cases used the organ system from practice while the other concepts presented in both novel and familiar organ systems. Half of the sample repeated testing after 1 week delay. The outcome was ratings of explanations of cases on a 0-3 scale. The effect of analogy was significant (Mean = 1.24 with, 0.86 without, F(1,22) = 4.26, p < 0.05) but not after delay (means of 1.08 and 0.75 respectively, F = (1,10), p = 0.06) There was significant effect for familiar context (Same = 1.23 (Starling), different = 0.68 (Laplace) and 0.73 (laminar-turbulent flow) (F(2,44) = 5.14, p < 0.01). Laplace's law and laminar turbulent flow cases in the familiar organ system had means of 1.65 and 1.77 respectively compared to novel cases with means of 0.74 and 0.68 (F(1,22) = 35.64, p < 0.0001). Similar effects were observed after delay. There was significant decay in performance after delay for all participants (immediate = 1.17, delayed = 0.91, F = 11.9 (1,10) p < 0.01). Common analogies aid conceptual understanding necessary for transfer. Despite conceptual aids, solving transfer problems is difficult.     

Mycobacterium xenopi osteomyelitis in a patient on highly active antiretroviral therapy (HAART)

Skeletal infections with atypical mycobacteria are a manifestation of advanced HIV disease, most patients having CD4 counts of less than 100 cells/mm(3). We report a case of Mycobacterium xenopi vertebral osteomyelitis in a patient on HAART with a CD4 count of 490 cells/mm(3) and viral load below the level of detection at the time of diagnosis.     

Vaccination against hepatitis B in an HIV outpatients' department: an audit against national vaccination guidelines

Practice related to hepatitis B vaccination of HIV outpatients in a London teaching hospital was audited against the British HIV Association (BHIVA) immunization guidelines 2004 and 2008, both before and after the implementation of a vaccination record sheet in the patients' notes. Adherence to the guidelines in the original audit was poor - only 67% of patients requiring vaccination for hepatitis B received a full course of vaccination. Following the introduction of the vaccination record sheet, this vaccination completion rate increased to 79% (BHIVA target 95%). Overall the percentage of patients managed according to BHIVA guidelines, including those who did not require vaccination, improved from 33% in the original audit to 61% in the re-audit. Introduction of a simple hepatitis B vaccination record sheet improved the quality of care for our HIV outpatients. Further modification of this system is warranted, perhaps by the introduction of a computerized reminder system.     

K65R and Y181C are less prevalent in HAART-experienced HIV-1 subtype A patients

The vast majority of HIV-1 infections globally are caused by subtype A or C, although little is known about their drug resistance profiles. We found that HAART-experienced patients infected with subtype A had a lower prevalence of K65R and Y181C than those with subtypes B or C, despite similar exposure to antiretroviral agents that select for these mutations. If confirmed, this information may be important in the planning of antiretroviral regimens in patients infected with HIV-1 subtype A.     

Cardiovascular risk evaluation and antiretroviral therapy effects in an HIV cohort: implications for clinical management: the CREATE 1 study

Aims: The aim of this study is to determine the cardiovascular disease (CVD) risk profile of a large UK HIV cohort and how highly active antiretroviral therapy (HAART) affects this. Methods: It is a cross‐sectional study within a large inner city hospital and neighbouring district hospital. A total of 1021 HIV positive outpatients representative of the complete cohort and 990 who had no previous CVD were included in CVD risk analysis. We recorded demographics, HAART history and CVD risk factors. CVD and coronary heart disease (CHD) risks were calculated using the Framingham (1991) algorithm adjusted for family history. Results: The non‐CVD cohort (n = 990) was 74% men, 51% Caucasian and 73.1% were on HAART. Mean age was 41 ± 9 years, systolic blood pressure 120 ± 14 mmHg, total cholesterol 4.70 ± 1.05mmol/l, high‐density lipoprotein‐C 1.32 ± 0.48 mmol/l and 37% smoked. Median CVD risk was 4 (0–56) % in men and 1.4 (0–37) % in women; CHD risks were 3.5 (0–36) % and 0.6 (0–16) %. CVD risk was > 20% in 6% of men and 1% of women and > 10% in 12% of men and 4% of women. CVD risk was higher in Caucasians than other ethnicities; the risk factor contributing most was raised cholesterol. For patients on their first HAART, increased CHD risk (26.2% vs. 6.5%; odds ratio 4.03, p < 0.001) was strongly related to the duration of therapy. Conclusions: Modifiable risk factors, especially cholesterol, and also duration of HAART, were key determinants of CVD risk. Discussion: Regular CHD and/or CVD risk assessment should be performed on patients with HIV, especially during HAART therapy. The effect of different HAART regimens on CHD risk should be considered when selecting therapy.
