Teaching Pharmacology in an Innovative Medical Curriculum: Challenges of Integration, Technology, and Future Training

Factors affecting pharmacology learning in integrated PBL in diverse medical students: a mixed methods study

INTRODUCTION

Problem-based learning (PBL) was introduced to address passive teaching limitations. However, it is not fully characterised as a teaching modality in pharmacology. The present study investigated the factors affecting pharmacology learning in an integrated PBL-based curriculum in diverse learners.

METHODS

Year 1 undergraduate medical students from two cohorts at St. George's University of London and University of Nicosia, participated. Statistical analysis of pharmacology knowledge scores, at the beginning (pre-test) and end of the academic year (post-test), investigated readiness to benefit from PBL based on diverse student characteristics (educational background, age, gender, country of origin, ethnicity, native language, PBL experience). Focus groups/interviews and a survey investigated aspects of integrated PBL impacting learning in depth.

RESULTS

Pre- and post-test scores were positively correlated. Students with biomedical sciences degrees performed better at the pharmacology pre- and post-tests, while post-graduate degree holders performed better only at the pre-test. Effect size was of moderate magnitude. However, progress in learning (post-test performance after controlling for pre-test scores) was unaffected. Qualitative analysis revealed three major themes: 1) PBL as a learning environment; 2) PBL as a learning environment in pharmacology; and 3) PBL as a learning environment and confidence in prescribing. Under theme one, skill development, knowledge acquisition through collaboration and self-directed learning, group dynamics and preferred teaching methods were discussed. Under theme two, contextual learning, depth of knowledge and material correctness were raised. Under theme 3, students expressed variability in prescribing confidence. They perceived that learning could be improved by better integration, further references earlier on, more lectures and PBL facilitators with greater content expertise. The survey findings were consistent with those from focus groups/interviews.

CONCLUSION

Pharmacology learning in a PBL-based curriculum is facilitated by constructive, collaborative and contextual learning. While baseline pharmacology knowledge may be advantageous, the other aforementioned characteristics studied may not affect readiness to benefit from PBL. However, further instructional scaffolding is needed, for example through further resources, lectures and self-assessment. The results from our study can inform evidence-based curriculum reform to support student learning further. Addressing learning needs could ultimately contribute to reducing medication errors through effective training of future prescribers.

Pharmacology education in the medical curriculum: Challenges and opportunities for improvement

The knowledge and application of pharmacology is essential for safe prescribing and administration of drugs. In this narrative review, the challenges to pharmacology education in the medical curricula were broadly identified to include issues around content and pedagogies. The increasing number of approved drugs and drug targets, expanding field of pharmacology and the often-changing treatment guidelines and board-defined competencies can make pharmacology education in the medical curriculum daunting. There has been a consensus around the deployment of innovative medical curricula with emphasis on vertical and horizontal integration. This strategy, effective as it has been, presents new challenges to pharmacology education. As a discipline often perceived by students to be hard-to-learn, the future of pharmacology education must include heavy reliance on active learning strategies. The continuing utilization of problem-based, team-based and case-based learning can be complemented with personalized learning which aims to identify the learning gaps in individual students. Technology-inspired student engagement can foster pharmacology learning and retention. Early exposure to pharmacology from premedical preparation through an enduring across-the-level integration can be an effective way to enhance pharmacology learning in the medical curricula.

High-level curricular integration in pharmacy schools: A systematic literature review

BACKGROUND

Pharmacy school accreditors recommend curricular integration. With today's complex health care system, there is also a need for more intentional and seamless blending, characterizing what we propose as "high-level curricular integration" (i.e. intentional "weaving" of multiple disciplines to form a coherent whole). Despite accreditors' recommendations, the practical definition and implementation guidelines of high-level curricular integration are not clear. We aimed to describe high-level curricular integration practices in pharmacy schools by systematically reviewing the literature addressing four elements of high-level curricular integration. These were (1) organizational thread, (2) pedagogies, (3) evaluation strategies, and (4) barriers.

METHODS

A PRISMA-guided (preferred reporting items for systematic reviews and meta-analyses) literature search strategy was conducted to examine the scientific literature. Inclusion criteria were English written literature related to one or more of the four elements of high-level curricular integration in pharmacy schools.

RESULTS

After screening titles, abstracts, and full texts, 28 articles were included. The most used organizational thread was disease-oriented (n = 8, 28.5%), and the most reported pedagogy was case studies (n = 11, 39%). Over half of the studies reported how the integration experience was evaluated. Most studies addressed barriers (n = 21, 75%), with the most reported barriers being time (n = 12, 42%) and workload (n = 12, 42%).

IMPLICATIONS

This review aimed to define and describe high-level integration within schools of pharmacy through four elements. Numerous and diverse trends were identified, and these four elements should be considered when planning, implementing, evaluating, and reporting curriculum integration experiences.

Pharmacology education: Reflections and challenges

Pharmacology is one of the cornerstones in health sciences curricula as well as research-oriented biomedical programs in higher education. New educational insights and scientific developments in teaching and learning, as well as exciting discoveries in pharmacology research, must prompt pharmacology teachers to regularly rethink and adjust their teaching. Reflecting on pharmacology education, this paper touches upon some educational issues that might inspire readers of this journal who are involved in pharmacology teaching.

Development and validation of an instrument to assess the prescribing readiness of medical students in Malaysia

BACKGROUND

Prescribing incompetence is an important factor that contributes to prescribing error, and this is often due to inadequate training during medical schools. We therefore aimed to develop and validate an instrument to assess the prescribing readiness of medical students (PROMS) in Malaysia.

METHODS

The PROMS comprised of 26 items with four domains: undergraduate learning opportunities; hands-on clinical skills practice; information gathering behaviour; and factors affecting the learning of prescribing skills. The first three domains were adapted from an existing questionnaire, while items from the last domain were formulated based on findings from a nominal group discussion. Face and content validity was determined by an expert panel, pilot tested in a class of final year (Year 5) medical students, and assessed using the Flesch reading ease. To assess the reliability of the PROMS, the internal consistency and test-retest (at baseline and 2 weeks later) were assessed using the Wilcoxon Signed Ranks test and Spearman's rho. The discriminative validity of the PROMS was assessed using the Mann-Whitney U-test (to assess if the PROMS could discriminate between final year medical students from a public and a private university).

RESULTS

A total of 119 medical students were recruited. Flesch reading ease was 46.9, indicating that the instrument was suitable for use in participants undergoing tertiary education. The overall Cronbach alpha value of the PROMS was 0.695, which was satisfactory. Test-retest showed no difference for 25/26 items, indicating that our instrument was reliable. Responses from the public and private university final year medical students were significantly different in 10/26 items, indicating that the PROMS was able to discriminate between these two groups. Medical students from the private university reported fewer learning opportunities and hands-on practice compared to those from the public university. On the other hand, medical students from the private university reported more frequent use of both web based and non-web-based resources compared to their public university counterparts.

CONCLUSIONS

The PROMS instrument was found to be a reliable and valid tool for assessing medical students' readiness to prescribe in Malaysia. It may also inform on the adequacy of medical programmes in training prescribing skills.
