Problem-based learning improves the academic performance of medical students in South Africa

Bioethics curriculum for undergraduate medical students: an evaluation study utilizing mixed methods approach

BACKGROUND

The undergraduate bioethics curriculum introduced in a private medical college in Pakistan in 1988 and revised in 2009 has evolved over time to incorporate globally relevant innovations, including integration of bioethics spirally within an existing problem-based learning curricular framework. The present evaluation study shares the results of this integrated bioethics curriculum delivered for 10 years across the five-year undergraduate medical curriculum. The study assessed the effectiveness of the curriculum in terms of student achievement, appropriateness of course contents and efficiency of instructional methods.

METHODS

The study utilized a mixed method sequential explanatory design. The quantitative method was used in the first phase to gather data by utilizing a structured online questionnaire. This was followed by the second phase of qualitative methods to explain the findings of the first phase and enrich the data gathered. This phase was based on focus group discussions and document review.

RESULTS

Student and faculty responses showed the curriculum contents to be relevant, informative, and appropriate as per learning objectives and student achievement. Multi-modal instructional methods used were stated to be effective and engaging; small group teaching and shorter sessions suggested to be preferable for fostering discussion and maintaining student engagement and attention. Large class formats were stated to be less effective. Students affirmed the contribution of bioethics education to their personal and professional development and ethical positioning. The majority of students agreed that the curriculum contributed to their knowledge acquisition (60.3-71.2%), skill development (59.41-60.30%) and demonstration of ethical/professional behavior (62.54-67.65%). The ranges indicate agreement with related sets of questions. Participants suggested that the curriculum could be further strengthened by better integration in clinical years, role modelling and providing opportunities for application in clinical health care settings. Moreover, topics like ethical issues related to the use of social media, public health ethics and ethics and law were suggested as additions to the existing curriculum. These findings have regional and global relevance for the development and assessment of effective bioethics curricula.

CONCLUSION

An effective bioethics curriculum for undergraduate medical education should run longitudinally across the 5 year curriculum and be integrated in the modules and clerkships. Basic acquisition of knowledge and skills takes place in Years 1 & 2 with reinforcement and application in Years 3-5. Learning embedded in an integrated curriculum can help students recognize, critically analyze and address ethical dilemmas. Involvement and commitment of the clinical faculty is essential for reinforcing the ethical principles and concepts learnt in the earlier years.

Assessing predictors of students' academic performance in Ethiopian new medical schools: a concurrent mixed-method study

BACKGROUND

Since 2012 the Ethiopian Federal Ministry of Health and Education implemented a new medical curriculum in 13 institutions. The new curriculum introduced some questions on its admission policy: students can join with different educational backgrounds. Students' performance on qualifying exams and grade point average are lower than desired. Therefore, the aim of the study was to investigate what factors predict the academic performance of students in the New Medical Education Initiative in Ethiopia.

METHODS

A concurrent mixed method of survey and qualitative was used; for the survey, a structured self-administered questionnaire was distributed to students of four randomly selected medical schools from December 2018 to January 2019. The questionnaire includes questions about socio-demographic and educational background of participants. Multiple linear regression analysis was used in order to identify the factors associated with academic performance. In-depth interviews were conducted with 15 key informants to explore qualitatively.

RESULTS

In the multiple linear regressions, stress was associated with lower academic performance. Students with prior education in the field of health science outperformed students with other bachelors. The cumulative grade point average of the previous bachelor degree and the score on the entrance exam to join medicine also significantly predicted performance. Although some more variables are identified from the qualitative interviews, its findings supported the survey results.

CONCLUSIONS

Of the number of predictor variables analyzed in the model, only stress, prior educational degree, performance in the prior degree and entrance exam score were significantly correlated with the performance of students in their preclinical medical engagement.

Using document phenomenology to investigate academic failure among year 1 undergraduate Malaysian medical students

BACKGROUND

Academic failure is common among medical schools worldwide. However, the process behind this failure itself is underexplored. A deeper understanding of this phenomenon may avert the vicious cycle of academic failure. Hence, this study investigated the process of academic failure among medical students in Year 1.

METHODS

This study employed a document phenomenological approach, which is a systematic process to examine documents, interpret them to attain understanding, and develop empirical knowledge of the phenomenon studied. Using document analysis, interview transcripts and reflective essays of 16 Year 1 medical students who experienced academic failure were analysed. Based on this analysis, codes were developed and further reduced into categories and themes. Thirty categories in eight themes were linked to make sense of the series of events leading to academic failure.

RESULTS

One or more critical incidents commenced during the academic year, which led to possible resulting events. The students had poor attitudes, ineffective learning methods, health problems or stress. Students progressed to mid-year assessments and reacted differently to their results in the assessments. Afterwards, the students tried different types of attempts, and they still failed the end-of-year assessments. The general process of academic failure is illustrated in a diagram describing chronological events.

CONCLUSION

Academic failure may be explained by a series of events (and consequences) of what students experience and do and how they respond to their experiences. Preventing a preceding event may prevent students from suffering these consequences.

How Do Curricular Design Changes Impact Computer Science Programs?: A Case Study at San Pablo Catholic University in Peru

Computer science is a dynamic field of study that requires constant review and updating of the curricular designs in academic programs—in general, measuring the impact of plan changes has been little explored in the literature. In most cases, it focuses only on structuring its curricula, leaving aside several factors associated with important events or facts such as student dropout, retention, and inclusion. However, these features provide academic institutions with many opportunities to understand student performance and propose more effective preventive/corrective actions to avoid dropouts. This work focuses on the curricular changes’ influence on student gender imbalance, socioeconomic provenance, and dropout. Specifically, we employ three different approaches for our analysis: (i) a longitudinal study of four curricula from informatics engineering to computer science transition at San Pablo Catholic University, (ii) an exploratory analysis for identifying essential features that determines the events mentioned above, and (iii) a survival analysis to estimate the probability that a student will stay (not dropout) before graduate, and calculate the average permanence time per curricula. Our analysis shows that the female student rates decreased, student rates from lower socioeconomic provenance increased, and the dropout rates were reduced with updates towards an internationally standardized curriculum. This is even strongly evidenced when the program changes its name. Finally, the set of techniques employed in this work composes a statistical mechanism that can be replicated/adapted to any other program in computer science aiming to extract valuable insights to support the decision-making process in educational institutions.

Recommendations for integration of foundational and clinical sciences throughout the pharmacy curriculum

INTRODUCTION

Pharmacy faculty have the often difficult task of translating and incorporating existing concepts and advances from the foundational sciences into the clinical sciences and practice. This commentary focuses on content integration as a curricular and educational strategy, outcomes data from integration, and recommendations for programs employing or considering curricular integration.

COMMENTARY

Integration of foundational and clinical sciences across the curriculum has been emphasized in accreditation standards but met with mixed reactions by faculty across different disciplines in the academy. Many pharmacy programs have already incorporated some level of integration in didactic courses. However, most report coordination of curricular delivery rather than higher levels of integration in which different disciplines work together to design and deliver instructional materials across the entire curriculum.

IMPLICATIONS

Curricular integration models should be optimized to minimize or eliminate the risks of marginalization of foundational sciences in pharmacy curricula. A significant problem in implementing curricular integration is determining the appropriate balance between foundational and clinical sciences. Well-designed curricular integration with ongoing reinforcement that builds in complexity over time could enhance knowledge retention, critical thinking abilities, and clinical decision making. Further research is needed into the outcomes achieved from various integrated curricular approaches in pharmacy education.

Does a socially-accountable curriculum transform health professional students into competent, work-ready graduates? A cross-sectional study of three medical schools across three countries

Background: Socially-accountable health professional education (SAHPE) is committed to achieving health equity through training health-workers to meet local health needs and serve disadvantaged populations. This research assesses the biomedical and socially-accountable competencies and work-readiness of first year graduates from socially-accountable medical schools in Australia, the United States and Sudan.Method: A self-administered survey to hospital and community health facility staff closely associated with the training and/or supervision of first year medical graduates from three SAHPE medical schools.Main outcome measure: Likert scale ratings of key competencies of SAHPE graduates (as a group) employed as first-year doctors, compared to first year doctors from other medical schools in that country (as a group).Findings: Supervisors rated medical graduates from the 3 SAHPE schools highly for socially-accountable competencies ('communication skills', 'teamwork', 'professionalism', 'work-readiness', 'commitment to practise in rural communities', 'commitment to practise with underserved ethnic and cultural populations'), as well as 'overall performance' and 'overall clinical skills'.Interpretation: These findings suggest SAHPE medical graduates are well regarded by their immediate hospital supervisors, and SAHPE can produce a medical workforce as competent as from more traditional medical schools, but with greater commitment to health equity, working with underserved populations, and addressing local health needs.

Problems of problem-based learning: Towards transformative critical pedagogy in medical education

Problem-based medical education is based in a biomedical worldview that works to entrench deterministic ways of thinking about socioculturally-influenced health disparities in the minds of medical trainees. This perspective paper considers the utility of Paolo Freire's critical pedagogy as a means of redressing this issue, as it may enable medical learners to perceive and address the social sources of illness that shape their patients' lives. With an eye to advancing health equity, and educating health professionals who are responsive to marginalized and vulnerable communities, this paper considers how a problem-posing medical education could redefine physicians' relationships to knowledge, identity, and to their patients.

The influence of different curriculum designs on students' dropout rate: a case study

The relationship between students' withdrawal and educational variables has generated a considerable number of publications. As the explosion of information in sciences and integration theories led to creating different curriculum designs, it has been assumed that differences among designs explain academic success and, therefore, students' retention. However, little attention has been given to examine explicitly how diverse designs influence dropout rates in practice, which questions if decisions to reform curricula are sufficiently informed. This article describes our curriculum reform, which exposes our former and current curriculum designs as having had dissimilar dropout percentages. Furthermore, we aimed to explore the influence of different curriculum designs on students' dropout rates. The conclusion is that dropout variations may be explained not only because of the curriculum design itself, but also because of the power relationship changes between teachers and students that brought out the design change. Consequently, more research is needed to fully understand the political implications of different curriculum designs and their influence on dropout rates.

Combined administration of problem- and lecture-based learning teaching models in medical education in China: A meta-analysis of randomized controlled trials

INTRODUCTION

The aim of this meta-analysis is to assess the effectiveness of the combined administration of problem-based learning (PBL) and lecture-based learning (LBL) teaching models in Chinese medical education.

MATERIALS AND METHODS

We searched the following Chinese electronic databases: China National Knowledge Infrastructure, WanFang Data, China Science Periodical Database, and the Chinese BioMedical Literature Database. We also searched the following English electronic databases: PubMed, Embase, Cochrane Central Register of Controlled Trials, and Google Search Engine. We searched for published studies involving the combined administration of PBL+LBL teaching models in Chinese medical education. All randomized controlled trials were included. The focus of the meta-analysis was on the outcomes of knowledge scores, skill scores, medical writing scores, comprehensive ability scores and teaching satisfaction. A subgroup analysis was also performed.

RESULTS

A total of 23 RCTs were included, with a total sample size of 2589 medical students. The PBL+LBL teaching model significantly increased knowledge scores (95% CI, 2.85-5.78; P < .00001), skill scores (95% CI, 0.51-3.71; P = .01), medical writing scores (95% CI, 1.04-4.04; P = .0009), comprehensive ability scores (95% CI, 2.04-8.71; P = .002) and teaching satisfaction (RR, 1.32; 95% CI, 1.10-1.59; P = .003) compared with the LBL teaching model alone. Additionally, a subgroup analysis showed significant differences in the effect of PBL+LBL on knowledge scores, medical writing scores, and comprehensive ability scores when comparing practical and theoretical courses. Another subgroup analysis that looked at the level of training showed that the PBL+LBL teaching model also significantly improved the knowledge scores of Freshman, Sophomore, Junior, Senior and Masters students.

DISCUSSION AND CONCLUSIONS

Based on the current evidence, this meta-analysis showed that the PBL+LBL teaching model is an effective way to increase knowledge scores, skill scores, medical writing scores, and comprehensive ability scores and to improve teaching satisfaction.

The impact of socially-accountable, community-engaged medical education on graduates in the Central Philippines: Implications for the global rural medical workforce

INTRODUCTION

Developing and retaining a high quality medical workforce, especially within low-resource countries has been a world-wide challenge exacerbated by a lack of medical schools, the maldistribution of doctors towards urban practice, health system inequities, and training doctors in tertiary centers rather than in rural communities.

AIM

To describe the impact of socially-accountable health professional education on graduates; specifically: their motivation towards community-based service, preparation for addressing local priority health issues, career choices, and practice location.

METHODS

Cross-sectional survey of graduates from two medical schools in the Philippines: the University of Manila-School of Health Sciences (SHS-Palo) and a medical school with a more conventional curriculum.

RESULTS

SHS-Palo graduates had significantly (p < 0.05) more positive attitudes to community service. SHS-Palo graduates were also more likely to work in rural and remote areas (p < 0.001) either at district or provincial hospitals (p = 0.032) or in rural government health services (p < 0.001) as Municipal or Public Health Officers (p < 0.001). Graduates also stayed longer in both their first medical position (p = 0.028) and their current position (p < 0.001).

CONCLUSIONS

SHS-Palo medical graduates fulfilled a key aim of their socially-accountable institution to develop a health professional workforce willing and able, and have a commitment to work in underserved rural communties.

The impact of socially-accountable health professional education: A systematic review of the literature

This literature review describes the impact of health professional schools with a social accountability mandate by identifying characteristics of medical education found to impact positively on medical students, health workforce, and health outcomes of disadvantaged communities. A critical appraisal tool was used to identify the strengths and weaknesses of the published articles. Data are presented as a narrative synthesis due to the variety of methodologies in the studies, and characterized using a logic model. Health professional schools aiming to improve health outcomes for their disadvantaged local communities described collaborative partnerships with communities, equitable selection criteria, and community-engaged placements in underserved areas as positively impacting the learning and attitudes of students. Students of socially accountable schools were more likely to stay in rural areas and serve disadvantaged communities, and were often more skilled than students from more traditional schools to meet the needs of underserved communities. However, published literature on the impact of socially accountable health professional education on communities and health outcomes is limited, with only one study investigating health outcomes. The findings of this literature review guide schools on the inputs likely to maximize their socially accountability outputs and increase their impact on students, local health workforce and local communities.

The validity of student tutors' judgments in early detection of struggling in medical school. A prospective cohort study

Early identification and support of strugglers in medical education is generally recommended in the research literature, though very little evidence of the diagnostic qualities of early teacher judgments in medical education currently exists. The aim of this study was to examine the validity of early diagnosis of struggling in medical school based on informal teacher judgements of in-class behavior. The study design was a prospective cohort study and the outcomes/truth criteria were anatomy failure and medical school drop out. Six weeks into an anatomy course, student tutors attempted to identify medical students, who they reckoned would fail the anatomy course or drop out, based on their everyday experiences with students in a large group educational setting. In addition, they were asked to describe the indicators of struggling they observed. Sixteen student tutors evaluated 429 medical students for signs of struggling. By week six, the student tutors were able to detect approximately 1/4-1/3 of the students who eventually failed or dropped out, and for ¾ of the strugglers they identified, they were correct in their judgments. Informal student tutor's judgements showed incremental validity for both outcomes when controlling for grades obtained in preceeding exams. Lack of participation, lack of commitment, poor academic performance, poor social interactions and general signs of distress were the main indicators of struggling identified. Teachers' informal judgements of in-class behavior may be an untapped source of information in the early identification of struggling medical students with added value above and beyond formal testing.

Utilizing students' experiences and opinions of feedback during problem based learning tutorials to develop a facilitator feedback guide: an exploratory qualitative study

BACKGROUND

Feedback delivery within a Problem Based Learning tutorial is a key activity for facilitators in order to enhance student learning. The purpose of this study was to explore students' experiences of feedback delivery in a PBL tutorial and use this information to design a feasible facilitator feedback delivery guide.

METHODS

It was an exploratory qualitative study in which individual interviews and focus group discussions were conducted with students who had an experience of the tutorial process. Data were collected through audio recording and writing of field notes. Thematic analysis was employed to generate the reported themes.

RESULTS

Students suggested that facilitators need to give comprehensive feedback on their knowledge construction process as well as feedback on other generic skills outside the knowledge domain such as their communication skills within the tutorial, their participation and team work as well as their interpersonal skills and self-evaluation abilities. From the findings, a structured facilitator feedback delivery guide was developed.

CONCLUSION

In this study, we propose a structured feedback delivery guide for PBL facilitators that captures not only knowledge, but also other generic competencies. The guide is feasible in a wide range of contexts where PBL is institutionalized.

Problem-based learning in resource-poor settings: lessons from a medical school in Ghana

Problem-based learning (PBL) is arguably one of the most important innovations in medical education in the last century. The evident benefits of PBL and the changing face of medicine and medical education have led many institutions including those in resource-poor settings to consider the adoption of PBL curricula. However, experts are uncertain about how successful PBL will be in such settings, as literature on the implementation of PBL in resource-poor settings appears to be inadequate. The University of Cape Coast is located in a resource-poor setting, however, its medical school has used PBL curriculum since 2007. In a descriptive prose, this article discusses the PBL implementation processes, the challenges faced, the mitigation strategies employed, and the lessons learned at University of Cape Coast School of Medical Sciences (UCCSMS). The arguments fall under the broad themes of curricular structure, resource constraints, faculty development, and assessment. The peculiar socioeconomic situation of Ghana, challenges in funding of tertiary education, and the resource implications of PBL provided the context for the arguments. It emerged out of the discussion that PBL has to be implemented as whole curriculum to be effective. Regular faculty development activities on PBL and the alignment of assessment methods with PBL also emerged as important issues in the discussion. The article argues that in spite of its cost implication, a PBL curriculum can be successfully implemented in resource-constrained settings.

Characteristics and critical success factors for implementing problem-based learning in a human resource-constrained country

BACKGROUND

Problem-based learning (PBL) was introduced in Malawi in 2002 in order to improve the nursing education system and respond to the acute nursing human resources shortage. However, its implementation has been very slow throughout the country.

OBJECTIVES

The objectives of the study were to explore and describe the goals that were identified by the college to facilitate the implementation of PBL, the resources of the organisation that facilitated the implementation of PBL, the factors related to sources of students that facilitated the implementation of PBL, and the influence of the external system of the organisation on facilitating the implementation of PBL, and to identify critical success factors that could guide the implementation of PBL in nursing education in Malawi.

METHOD

This is an ethnographic, exploratory and descriptive qualitative case study. Purposive sampling was employed to select the nursing college, participants and documents for review.Three data collection methods, including semi-structured interviews, participant observation and document reviews, were used to collect data. The four steps of thematic analysis were used to analyse data from all three sources.

RESULTS

Four themes and related subthemes emerged from the triangulated data sources. The first three themes and their subthemes are related to the characteristics related to successful implementation of PBL in a human resource-constrained nursing college, whilst the last theme is related to critical success factors that contribute to successful implementation of PBL in a human resource-constrained country like Malawi.

CONCLUSION

This article shows that implementation of PBL is possible in a human resource-constrained country if there is political commitment and support.

The effectiveness of the problem-based learning teaching model for use in introductory Chinese undergraduate medical courses: a systematic review and meta-analysis

Background

Although the problem-based learning (PBL) emerged in 1969 and was soon widely applied internationally, the rapid development in China only occurred in the last 10 years. This study aims to compare the effect of PBL and lecture-based learning (LBL) on student course examination results for introductory Chinese undergraduate medical courses.

Methods

Randomized and nonrandomized controlled trial studies on PBL use in Chinese undergraduate medical education were retrieved through PubMed, the Excerpta Medica Database (EMBASE), Chinese National Knowledge Infrastructure (CNKI) and VIP China Science and Technology Journal Database (VIP-CSTJ) with publication dates from 1st January 1966 till 31 August 2014. The pass rate, excellence rate and examination scores of course examination were collected. Methodological quality was evaluated based on the modified Jadad scale. The I-square statistic and Chi-square test of heterogeneity were used to assess the statistical heterogeneity. Overall RRs or SMDs with their 95% CIs were calculated in meta-analysis. Meta-regression and subgroup meta-analyses were also performed based on comparators and other confounding factors. Funnel plots and Egger’s tests were performed to assess degrees of publication bias.

Results

The meta-analysis included 31studies and 4,699 subjects. Fourteen studies were of high quality with modified Jadad scores of 4 to 6, and 17 studies were of low quality with scores of 1 to 3. Relative to the LBL model, the PBL model yielded higher course examination pass rates [RR = 1.09, 95%CI (1.03, 1.17)], excellence rates [RR = 1.66, 95%CI (1.33, 2.06)] and examination scores [SMD = 0.82, 95%CI (0.63, 1.01)]. The meta-regression results show that course type was the significant confounding factor that caused heterogeneity in the examination-score meta-analysis (t = 0.410, P<0.001). The examination score SMD in “laboratory course” subgroup [SMD = 2.01, 95% CI: (1.50, 2.52)] was higher than that in “theory course” subgroup [SMD = 0.72, 95% CI: (0.56, 0.89)].

Conclusions

PBL teaching model application in introductory undergraduate medical courses can increase course examination excellence rates and scores in Chinese medical education system. It is more effective when applied to laboratory courses than to theory-based courses.

Assessment of lecture strategy with different teaching AIDS

BACKGROUND AND OBJECTIVES

Medical/dental colleges in Northern India cater to students with diverse backgrounds, mother tongues, levels of comprehending English, and intelligence levels. This study was conducted to identify lecture strategy and teaching aid best suited for North Indian dental and medical students. It was conducted in two parts - 1. Survey of teachers' and students' opinion to obtain their preferences in teaching-learning practices followed in a conventional lecture, and 2. Comparison of students' performances after a single trial lecture with different groups of students, using different teaching aids (TAs).

MATERIALS AND METHODS

Opinions of 33 faculty teaching first year dental/ medical students and 506 volunteer students (320 female) were compiled. Students were divided into four groups. A single trial lecture was held with each group (on the same topic, using identical lesson plan, by the same teacher) using a different teaching aid with each group. Lecture strategy was designed according to students' preferences (as obtained from opinion survey) regarding language of instruction and the number of mental breaks. TAs used with different groups were chalk and board (C&B), PowerPoint (PPT), overhead projector (OHP), and a combination of C&B and PPT. Pre- and post-tests using multiple choice questions were conducted with each group. RESULTS of post-test questionnaire and feedback from faculty attending the lecture were assessed for students' satisfaction and attentiveness in all four groups.

RESULTS

Survey results indicated that although 97.6% students believed they had good/fair proficiency in English, 83.6% preferred being taught in a combination of English and Hindi; 44.3% students preferred C&B, 40.1% preferred PPT and 15.6% preferred the use of OHP as TA. After conducting a trial lecture with different TAs with each group, more than 90% students expressed satisfaction with the TA used for that group. Significantly better performance was observed in the post-lecture test when C&B was used.

CONCLUSION

The needs of students in India are different from those of their Western counterparts, and should be considered during didactic lectures to improve the students' understanding. Post-test results were better when C&B was used, as more students were attentive and/or took notes.

Students' and junior doctors' preparedness for the reality of practice in sub-Saharan Africa

BACKGROUND

Evidence tailored to sub-Saharan Africa on outcomes of innovations in medical education is needed to encourage and advance their implementation in this region.

AIM

To investigate preparedness for practice of students and graduates from an innovative and a conventional medical curriculum in a sub-Saharan African context.

METHODS

Using mixed methods we compared junior doctors and fifth-year students from two Mozambican medical schools: one with an innovative problem- and community-based curriculum and one with a conventional lecture- and discipline-based curriculum. A questionnaire on professional competencies was administered, semi-structured interviews were conducted, and work diaries were collected. The findings were integrated in a conceptual model.

RESULTS

Six areas of tension between global health care ideals and local health care practice emerged from the data that challenged doctors' motivation and preparedness for practice. Four elements of the innovative curriculum equipped students and graduates with skills, attitudes and competencies to better cope with these tensions. Students and graduates from the innovative curriculum rated significantly higher levels on various competencies and expressed more satisfaction with the curriculum and its usefulness for their work.

CONCLUSION

An innovative problem- and community-based curriculum can improve sub-Saharan African doctors' motivation and preparedness to tackle the challenges of health care practice in this region.

Medical school attrition-beyond the statistics a ten year retrospective study

BACKGROUND

Medical school attrition is important--securing a place in medical school is difficult and a high attrition rate can affect the academic reputation of a medical school and staff morale. More important, however, are the personal consequences of dropout for the student. The aims of our study were to examine factors associated with attrition over a ten-year period (2001-2011) and to study the personal effects of dropout on individual students.

METHODS

The study included quantitative analysis of completed cohorts and qualitative analysis of ten-year data. Data were collected from individual student files, examination and admission records, exit interviews and staff interviews. Statistical analysis was carried out on five successive completed cohorts. Qualitative data from student files was transcribed and independently analysed by three authors. Data was coded and categorized and key themes were identified.

RESULTS

Overall attrition rate was 5.7% (45/779) in 6 completed cohorts when students who transferred to other medical courses were excluded. Students from Kuwait and United Arab Emirates had the highest dropout rate (RR = 5.70, 95% Confidence Intervals 2.65 to 12.27;p < 0.0001) compared to Irish and EU students combined. North American students had a higher dropout rate than Irish and EU students; RR = 2.68 (1.09 to 6.58;p = 0.027) but this was not significant when transfers were excluded (RR = 1.32(0.38, 4.62);p = 0.75). Male students were more likely to dropout than females (RR 1.70, .93 to 3.11) but this was not significant (p = 0.079).Absenteeism was documented in 30% of students, academic difficulty in 55.7%, social isolation in 20%, and psychological morbidity in 40% (higher than other studies). Qualitative analysis revealed recurrent themes of isolation, failure, and despair. Student Welfare services were only accessed by one-third of dropout students.

CONCLUSIONS

While dropout is often multifactorial, certain red flag signals may alert us to risk of dropout including non-EU origin, academic struggling, absenteeism, social isolation, depression and leave of absence. Psychological morbidity amongst dropout students is high and Student Welfare services should be actively promoted. Absenteeism should prompt early intervention. Behind every dropout statistic lies a personal story. All medical schools have a duty of care to support students who leave the medical programme.

Differential student attrition and differential exposure mask effects of problem-based learning in curriculum comparison studies

PURPOSE

Studies that compare the effects of problem-based and conventional medical curricula on student performance generally show no significant differences. However, curriculum comparison studies are at best quasi-experimental, so they are prone to forms of selection bias. The purpose of this study was to reanalyze data from such comparisons by controlling for two potential biases: differential student attrition and differential exposure.

METHOD

The authors reanalyzed 104 previously published comparisons involving a single, problem-based medical school in the Netherlands (Maastricht University's medical school), using student attrition and study duration data from this school and the schools with which it was compared. The authors removed bias by reequalizing the comparison groups in terms of attrition and study duration.

RESULTS

The uncorrected data showed no differences between problem-based and conventional curricula: Mean effect sizes as expressed by Cohen d were 0.02 for medical knowledge and 0.07 for diagnostic reasoning. However, the reanalysis demonstrated medium-level effect sizes favoring the problem-based curriculum. After corrections for attrition and study duration, the mean effect size for knowledge acquisition was 0.31 and for diagnostic reasoning was 0.51.

CONCLUSIONS

Effects of the Maastricht problem-based curriculum were masked by differential attrition and differential exposure in the original studies. Because this school has been involved in many studies included in influential literature reviews published in the past 20 years, the authors' findings have implications for the assessment of the value of problem-based learning put forward by these reviews.

Medical education in sub-Saharan Africa: a literature review

OBJECTIVES

This review synthesises research published in the traditional and 'grey' literature to promote a broader understanding of the history and current status of medical education in sub-Saharan Africa (SSA).

METHODS

We performed an extensive review and analysis of existing literature on medical education in SSA. Relevant literature was identified through searches of five traditional medical databases and three non-traditional or grey literature databases featuring many African journals not indexed by the traditional databases. We focused our inquiry upon three themes of importance to educators and policymakers: innovation; capacity building, and workforce retention.

RESULTS

Despite the tremendous heterogeneity of languages and institutions in the region, the available literature is published predominantly in English in journals based in South Africa, the UK and the USA. In addition, first authors usually come from those countries. Several topics are thoroughly described in this literature: (i) human resources planning priorities; (ii) curricular innovations such as problem-based and community-based learning, and (iii) the 'brain drain' and internal drain. Other important topics are largely neglected, including: (i) solution implementation; (ii) programme outcomes, and (iii) the development of medical education as a specialised field of inquiry.

CONCLUSIONS

Medical education in SSA has undergone dramatic changes over the last 50 years, which are recorded within both the traditionally indexed literature and the non-traditional, grey literature. Greater diversity in perspectives and experiences in medical education, as well as focused inquiry into neglected topics, is needed to advance medical education in the region. Lessons learned from this review may be relevant to other regions afflicted by doctor shortages and inequities in health care resulting from inadequate capacity in medical education; the findings from this study might be used to inform specific efforts to address these issues.

The process of problem-based learning: what works and why

OBJECTIVES

In this review, we portray the process of problem-based learning (PBL) as a cognitive endeavour whereby the learner constructs mental models relevant to problems. Two hypotheses are proposed to explain how learning is driven in PBL; an activation-elaboration hypothesis and a situational interest hypothesis.

METHODS

Research relevant to these hypotheses is discussed. In addition, research studying the effects of various support strategies used in PBL is reviewed. Finally, we summarise a number of recent studies in which a new 'micro-analytical' methodology was used to trace the process of PBL in the natural classroom setting.

CONCLUSIONS

We conclude that there is considerable support for the idea that PBL works because it encourages the activation of prior knowledge in the small-group setting and provides opportunities for elaboration on that knowledge. These activities facilitate the comprehension of new information related to the problem and enhance its long-term memorability. In addition, there is evidence that problems arouse situational interest that drives learning. Flexible scaffolding provided by cognitively and socially congruent tutors also seems to be reasonably effective, as opposed to 'hard' scaffolding represented by, for instance, worksheets or questions added to problems. Small-group work protects against dropout and encourages students to study regularly. Initially, students do not study much beyond the learning issues generated; the development of personal agency in self-study needs time to develop. The extent of learning in PBL results from neither group collaboration only (the social constructivist point of view) nor individual knowledge acquisition only; both activities contribute equally to learning in PBL.

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.

Situational analysis of teaching and learning of medicine and nursing students at Makerere University College of Health Sciences

Background

Makerere University College of Health Sciences (MakCHS) in Uganda is undergoing a major reform to become a more influential force in society. It is important that its medicine and nursing graduates are equipped to best address the priority health needs of the Ugandan population, as outlined in the government’s Health Sector Strategic Plan (HSSP). The assessment identifies critical gaps in the core competencies of the MakCHS medicine and nursing and ways to overcome them in order to achieve HSSP goals.

Methods

Documents from the Uganda Ministry of Health were reviewed, and medicine and nursing curricula were analyzed. Nineteen key informant interviews (KII) and seven focus group discussions (FGD) with stakeholders were conducted. The data were manually analyzed for emerging themes and sub-themes. The study team subsequently used the checklists to create matrices summarizing the findings from the KIIs, FGDs, and curricula analysis. Validation of findings was done by triangulating information from the different data collection methods.

Results

The core competencies that medicine and nursing students are expected to achieve by the end of their education were outlined for both programs. The curricula are in the process of reform towards competency-based education, and on the surface, are well aligned with the strategic needs of the country. But implementation is inadequate, and can be changed:

• Learning objectives need to be more applicable to achieving competencies.

• Learning experiences need to be more relevant for competencies and setting in which students will work after graduation (i.e. not just clinical care in a tertiary care facility).

• Student evaluation needs to be better designed for assessing these competencies.

Conclusion

MakCHS has made a significant attempt to produce relevant, competent nursing and medicine graduates to meet the community needs. Ways to make them more effective though deliberate efforts to apply a competency-based education are possible.

Addressing social responsibility in medical education: the African way

Indigenous sub-Saharan societies have, over the millennia, lived and socialised within the unwritten 'rules' of the 'Ubuntu' or similar philosophies that emphasises holistic 'humanness', and which is a form of 'social responsibility'. This article looks into some relevant social responsibility aspects of medical education in the South African context, with particular emphasis on how these aspects have been addressed. Apartheid was, by its very nature, incompatible with social responsibility for the majority of South Africans, but one medical school that was a non-complicit product of apartheid succeeded in fulfilling a socially responsible mission. Thus, this article implicitly identifies what South Africa, Africa and the global Health Professions Education community could learn from these trail-blazing experiences.

Problem-based learning in academic health education. A systematic literature review

Problem based learning (PBL) arguably represents the most significant development in education over the past five decades. It has been promoted as the curriculum of choice, and since its introduction in the 1960's, has been widely adopted by many medical and dental schools. PBL has been the subject of much published literature but ironically, very little high quality evidence exists to advocate its efficacy and subsequently justify the widespread curriculum change. The purpose of this review is to classify and interpret the available evidence and extract relevant conclusions. In addition, it is the intent to propose recommendations regarding the relative benefits of PBL compared with conventional teaching. The literature was searched using PubMed, ERIC and PsycLIT. Further articles were retrieved from the reference lists of selected papers. Articles were chosen and included according to specific selection criteria. Studies were further classified as randomised controlled trials (RCTs) or comparative studies. These studies were then analysed according to intervention type: whole curricula comparisons and single educational interventions of shorter duration. At the level of RCTs and comparative studies (whole curricula), no clear difference was observed between PBL and conventional teaching. Paradoxically, it was only comparative studies of single PBL intervention in a traditional curriculum that yielded results that were consistently in favour of PBL. Further research is needed to investigate the possibility that multiple PBL interventions in a traditional curriculum could be more effective than an exclusively PBL programme. In addition, it is important to address the potential benefits of PBL in relation to life-long learning of health care professionals.

Impact of problem-based, active learning on graduation rates for 10 generations of Dutch medical students

OBJECTIVES

We aimed to study the effects of active-learning curricula on graduation rates of students and on the length of time needed to graduate.

METHODS

Graduation rates for 10 generations of students enrolling in the eight Dutch medical schools between 1989 and 1998 were analysed. In addition, time needed to graduate was recorded. Three of the eight schools had curricula emphasising active learning, small-group instruction and limited numbers of lectures; the other five had conventional curricula to varying degrees.

RESULTS

Overall, the active-learning curricula graduated on average 8% more students per year, and these students graduated on average 5 months earlier than their colleagues from conventional curricula.

CONCLUSIONS

Four hypotheses potentially explaining the effect of active learning on graduation rate and study duration were considered: (i) active-learning curricula promote the social and academic integration of students; (ii) active-learning curricula attract brighter students; (iii) active-learning curricula retain more poor students, and (iv) the active engagement of students with their study required by active-learning curricula induces better academic performance and, hence, lower dropout rates. The first three hypotheses had to be rejected. It was concluded that the better-learning hypothesis provides the most parsimonious account for the data.

Anatomy: spotlight on Africa

Anatomy departments across Africa were surveyed regarding the type of curriculum and method of delivery of their medical courses. While the response rate was low, African anatomy departments appear to be in line with the rest of the world in that many have introduced problem based learning, have hours that are within the range of western medical schools and appear to be well resourced. Human body dissection is a constant and strong aspect of the majority of the courses surveyed. The staff to student ratio appears to be relatively high in Africa, but in many of the responding African institutions, there appears to be little difficulty in attracting suitable faculty (including those who are medically qualified) to teach anatomy. Retaining this faculty, in some cases, may be difficult because of a global demand for anatomy educators.

Problem-based learning, critical thinking and concept mapping in speech-language pathology education: A review

Despite speech-language pathology (SLP) education undergoing many innovative changes over the years, there has been little research about learning or outcomes in SLP programs. Critical thinking in clinical decision-making, however, has been identified as a critical skill in SLP. Several recent studies have shown that concept mapping can be used to assess, and perhaps enhance, critical thinking. Problem-based learning (PBL) is reported to be one way to encourage critical thinking and life-long learning. Here we review the literature in PBL, concept mapping, and critical thinking, focusing on the education of SLP students. The review illustrates the close and complex interactions amongst problem-based learning, critical thinking and concept mapping. The aim of the review is to provide a better understanding of the mechanism of PBL, and to increase understanding regarding why the employment of PBL in SLP programs may facilitate critically-thinking graduate clinicians. The evidence indicates that PBL allows more meaningful learning that promotes better integration between theory and clinical practice.

Addressing physician shortages in New Mexico through a combined BA/MD program

The University of New Mexico School of Medicine and College of Arts and Sciences developed its combined BA/MD degree program, which will increase the medical school class from 75 students to 100 in the fall of 2010, to address the critical issue of physician shortages in underserved New Mexico. The program, which began operation at the undergraduate (i.e., college) level in 2006, expands opportunities in medical education for New Mexico students, especially those from rural and underserved minority communities, and prepares them to practice in underserved areas of New Mexico. In the BA/MD program, students will earn a bachelor of arts, a medical degree, and a proposed certificate in public health. A challenging liberal arts curriculum introduces the principles of public health. Students have unique rural medicine and public health preceptorship opportunities that begin in the undergraduate years and continue throughout medical school. Students work with a community physician mentor in summer service-learning projects during the undergraduate years, then they return for required rural medicine rotations in the first, third, and fourth years of medical school. Simultaneously, the classroom curriculum for these rural medicine experiences emphasizes the public health perspective. High priority has been placed on supporting students with academic advising and counseling, tutoring, supplemental instruction, on-campus housing, and scholarships. The program has received strong support from communities, the New Mexico state legislature, the New Mexico Medical Society, and the faculties of arts and sciences and the school of medicine. Early results on the undergraduate level demonstrate strong interest from applicants, retention of participants, and enthusiasm of students and faculty alike.

Challenges in training the ideal Doctor for Africa: lessons learned from Zimbabwe

BACKGROUND

Limited competencies among doctors and reduced numbers from medical migration in Africa could be corrected through innovative curricula and retention of trained manpower. The University of Zimbabwe Medical School simultaneously decided to increase the quality and quantity of doctors to address shortages.

AIMS

To evaluate the outcome of innovative medical education at the University of Zimbabwe Medical School.

METHOD

A structured questionnaire was administered to a broad group of staff and student representatives. In addition, a desk review of academic documents and policies and procedures was carried out.

RESULTS

Early patient contact and community attachment which were introduced to the traditional curriculum remained but other teaching methodologies were not sustained with traditional didactic training still taking centre stage with limited staff development and retention. Whilst the annual student enrolment increased from less than 80 to 200 per year the vacancy rate of academic staff increased to 50%.

CONCLUSION

Innovative curricula were partially implemented. The annual student intake increased but the staff complement declined. There is an urgent need to monitor and evaluate outcomes of medical education in Africa to arrest further decline in the quality of health care services.

Performance of academically at-risk medical students in a problem-based learning programme: a preliminary report

INTRODUCTION

Racially segregated schooling, a legacy of Apartheid policies, continues to hamper education in South Africa. Students entering university from suboptimal circumstances are at significant risk of demonstrating poor academic performance and dropping out of their programmes. Attempts to address the educational needs of these students have included the introduction of extended medical programmes at several universities. Such a programme, the Academic Development Programme (ADP), was implemented at the University of Cape Town in 1991. Over the past decade the programme has graduated more than 100 students. Upon implementation of a new problem-based learning (PBL) programme in 2002, the ADP was discontinued and all students were entered directly into the new PBL programme. Students who demonstrate a need for additional academic support by the end of the first semester enter the Intervention Programme for 1 year before proceeding to the second semester of the PBL programme. An interim analysis was performed to compare the retention rates and academic performance of academically at-risk students in the new PBL programme and the ADP.

METHODS

The records of all academically at-risk students entering the ADP (1991-2000) and the new PBL programme (2002) were reviewed. Retention rates for all years of study, and academic performance in the fourth year clerkship courses of the respective programmes were compared.

RESULTS

A total of 239 academically at-risk students in the ADP and 43 at-risk students in the new PBL programme were studied. The median retention rates, per year of study, for at-risk students in the PBL programme was significantly better than for at-risk students in the ADP (p<0.02). Academic performance of the at-risk students in all the fourth year clinical clerkship courses of the PBL programme was significantly better than the mean performance over 10 years for at-risk students in the same fourth year courses in the ADP.

CONCLUSION

The introduction of PBL at the University of Cape Town has not had a deleterious effect on the performance of academically at-risk medical students. Interim analysis suggests that retention rates and academic performance in the PBL programme are better than those achieved in the extended traditional programme.

Revitalizing problem based learning: student and tutor attitudes towards a structured tutorial

BACKGROUND

The pre-clinical curriculum at the University of New Mexico School of Medicine is a hybrid model that includes small group, problem-based learning (PBL) tutorials and didactic lectures. A structured tutorial format was piloted for the human sexuality/reproduction organ system block for the PBL component. The objective of this study was to compare the acceptability of the structured format and its effectiveness with that of a traditional PBL tutorial.

METHODS

Students were surveyed after the renal/endocrinology block of 2004 (traditional tutorial format) and after the human sexuality/reproduction block of 2004 (structured tutorial format) (n = 70). Survey questions covered the quality of learning and of tutorial. Students (n = 132) and tutors (n = 24) who participated in human sexuality/reproduction in 2004 and 2005 were surveyed for attitudes about the structured tutorial overall and specific components. Means of responses were compared using t-tests.

RESULTS

Students indicated that the structured tutorial format supported a greater improvement in their basic science and clinical knowledge and their ability to evaluate information (p < 0.05). The majority of students and tutors recommended the structured format for tutorials in other blocks.

CONCLUSIONS

We demonstrated the acceptability of a structured tutorial format to students and faculty. Faculty members perceived greater depth of learning and participation by the students.

Training Medical Students in the Community - Memoirs and Reflections of the University of Transkei Medical School

Not long after its inception, the undergraduate medical program at the University of Transkei (UNITRA) departed from the traditional hospicentric medical education approach to one tailored around a Community-Based Medical Education (CBME) curriculum adopting the Problem-based Learning (PBL) pedagogy. This article reflects on the experiences of the faculty in establishing and implementing CBME, exploring what it has meant to train medical students in the community. It further appraises CBME by reviewing its impact on students, the faculty, and the community at large.

Integrated problem-based learning in the neuroscience curriculum--the SUNY Downstate experience

BACKGROUND

This paper reports the author's initial experience as Block Director in converting a Conventional Curriculum into a problem-based learning model (PBL) for teaching Psychopathology. As part of a wide initiative in curriculum reform, Psychopathology, which was a six-week course in the second-year medical school curriculum, became integrated into a combined Neuroscience block. The study compares curriculum conversion at State University of New York (SUNY), Downstate, with the experiences at other medical centres that have instituted similar curricula reform.

METHODS

Student satisfaction with the Conventional and PBL components of the Neuroscience curriculum was compared using questionnaires and formal discussions between faculty and a body of elected students. The PBL experience in Psychopathology was also compared with that of the rest of the Neuroscience Block, which used large student groups and expert facilitators, while the Psychopathology track was limited to small groups using mentors differing widely in levels of expertise.

RESULTS

Students appeared to indicate a preference toward conventional lectures and large PBL groups using expert facilitators in contrast to small group mentors who were not experts. Small PBL groups with expert mentors in the Psychopathology track were also rated favorably.

CONCLUSION

The study reviews the advantages and pitfalls of the PBL system when applied to a Neuroscience curriculum on early career development. At SUNY, conversion from a Conventional model to a PBL model diverged from that proposed by Howard S. Barrows where student groups define the learning objectives and problem-solving strategies. In our model, the learning objectives were faculty-driven. The critical issue for the students appeared to be the level of faculty expertise rather than group size. Expert mentors were rated more favorably by students in fulfilling the philosophical objectives of PBL. The author, by citing the experience at other major Medical Faculties, makes a cautious attempt to address the challenges involved in the conversion of a Psychopathology curriculum into a PBL dominated format.
