Background: The Prescribing Safety Assessment (PSA) is an online assessment of safe and effective prescribing, taken by final-year UK medical students. To prepare students for the PSA, we used a modified form of team-based learning, team-based revision (TBR), in which students consolidate previously learned prescribing knowledge and skills across a broad range of topics. We evaluated students’ response to TBR and their perceptions of team working.
Methods: Eight TBR sessions based on the PSA blueprint were conducted over two days by three faculty members for final year medical students. During TBR sessions, students worked in small groups answering individual multiple-choice questions, followed by group multiple-choice questions. They subsequently answered open-ended questions in their groups, with answers written on a drug chart to increase authenticity. Students completed surveys using Likert-type items to determine views on TBR and their confidence in prescribing.
Results: The majority of respondents agreed that the sessions were useful for preparation both for the PSA (82%) and Foundation Year 1 (78%). 92% agreed that using drug-charts aided learning. Prescribing confidence increased significantly after TBR (median pre-TBR: 2, post-TBR: 5, p<0.0001). TBR significantly improved attitudes towards “team experience” (p<0.001), “team impact on quality of learning” (p<0.01) and “team impact on clinical reasoning ability” (p<0.001).
Conclusions: Team-based revision is a resource-efficient addition to undergraduate prescribing teaching and can help with preparation for the PSA. A short course of TBR was effective in influencing students’ attitudes towards teamwork.

Introduction

The ability to prescribe safely and effectively is a key learning outcome for undergraduate education. The Prescribing Safety Assessment (PSA) has been developed by the British Pharmacological Society and Medical Schools Council to enable final-year medical students to demonstrate that the required outcomes have been met.1 The advent of electronic health records and electronic prescriptions that can only be generated by qualified doctors has introduced new challenges in undergraduate teaching and practice of this key competency.

Team-based learning (TBL) offers a student-centered approach to teaching that maintains individual accountability alongside teamwork and active learning.2,3 TBL provides a “flipped classroom” approach, whereby students acquire knowledge in their own time in preparation for the teaching session, and class time with the instructor is used to develop teamwork and higher order skills like problem solving and decision-making.4 TBL has demonstrated results comparable to lecture-based teaching, is particularly effective in improving academic performance of weaker students,57 and is well received by medical students and staff.58 During the final year at medical school, a particular emphasis is placed on readiness to practice, with a focus on consolidation of knowledge and clinical skills, and development of non-clinical skills. The interactive nature of TBL, its focus on non-clinical skills development, and the active learning component, mean it is particularly well suited for final year students. Team-based learning has been shown to promote student engagement,9 as well as professionalism, teamwork and communication skills.4 In addition, TBL has been shown to be effective in delivering pharmacology education.3,7,10,11

TBL comprises three phases: phase 1 involves self-directed learning on the contents to be discussed later in the classroom. Phase 2 is split into two sub-sections: the first involves individual readiness assurance tests, where knowledge acquired in phase 1 is tested. The second involves the same readiness assurance test, this time taken as a group, alongside the opportunity to discuss with the instructor. Phase 3 involves higher levels of learning through using teamwork to tackle more complex course concepts.3 TBL is used to aid learning new content for a limited number of topics during each session. We developed a modified form of TBL, team-based revision (TBR), to enable students to revisit and consolidate previously learned information across a broad range of topics. The medical curriculum at Imperial College London encompasses two science-focused years (Years 1 and 2) and three years of clinical placements (Years 3, 5 and 6). During Year 4, students work towards a BSc by undertaking a series of modules and a supervised research project. The student body comprises primarily undergraduates, with a proportion of postgraduates. We examined the utility of TBR in preparing final year medical students for the PSA. We evaluated the acceptability of TBR, and whether a short course of TBR can influence students’ and attitudes towards teamwork. As a major focus of the final year curriculum is to improve “readiness to practice”, we also used a basic scale to judge whether TBR could influence confidence in prescribing.

Methods

TBR design and participants

The study was approved by the Medical Education Ethics Committee at Imperial College London. Four 1.5 hr PSA-based TBR sessions were delivered for 201 final year medical students at Imperial College School of Medicine over two days, facilitated by three faculty members. TBR sessions had the same structure as TBL except for phase 1: rather than giving students new information to learn in their own time before the session, TBR made use of students’ pre-existing knowledge acquired during clinical placements.

Material for the sessions was developed by the Imperial College School of Medicine faculty, and was based on the Prescribing Safety Assessment (PSA) blueprint consisting of eight domains: Prescribing, Prescription Review, Planning Management, Providing Information, Calculation Skills, Adverse Drug Reactions, Drug Monitoring, and Data Interpretation within seven clinical settings: Medicine, Surgery, Elderly Care, Paediatrics, Psychiatry, Obstetrics and Gynecology and General Practice.12 TBR questions were written in a similar style to reflect the problem-solving and clinical reasoning that the assessment requires, and questions were reviewed by the Head of Year 6 Assessment and the Lead for Clinical Pharmacology and Therapeutics to ensure accuracy and relevance. Sessions took place at the start of students’ final year, seven months prior to sitting the PSA. As the students did not have extensive prior experience with TBL, we elected to hold the sessions at the beginning of their revision period rather than towards the end to reduce anxiety. The sessions were not compulsory, and all students who were present at the session completed the evaluation.

Students worked in teams of 6–8. During the TBR sessions, students first received a Multiple-Choice Question (MCQ) test using a cloud-based tool (SurveyMonkey). After answering the questions individually, students completed the same questions working as a group, using “instant feedback assessment technique” scratch cards. Subsequently facilitators led group discussions about the answers. Students had access to the British National Formulary (BNF) throughout the sessions.

Students were then given five clinically orientated cases and asked to prescribe appropriate medications on a drug chart as a group. All groups worked on the same questions. Students were subsequently taken through the correct answers by the facilitators.

Student questionnaires

All students were asked to complete a pre- and post-TBR questionnaire. The questionnaires were completed on iPads using SurveyMonkey to collect data, and written consent was gained from each participant prior to completing the survey. The questionnaire comprised two sections. The first section recorded self-rated confidence in prescribing on a 10-point scale, with 1 indicating “Not confident” and 10 indicating “Very confident”. The second section was a modified validated instrument developed to assess attitudes towards teamwork after TBR among medical students. It used a five-point Likert scale ranging from Strongly Disagree (1) to Strongly Agree (5) to assess teamwork-related attitudes in four broad domains (Table 1).13

Statistical analyses

Wilcoxon signed rank test was used to analyze paired data using PRISM Version 7.04 (GraphPad Software, Inc., San Diego, CA, USA).

Results

Acceptability of TBR and impact on prescribing confidence

Ninety-eight students responded to the questionnaire about their perceptions of TBR as a learning method after the course (Figure 1). 82% of medical students agreed/strongly agreed that TBR sessions helped their preparation for the PSA. 78% of medical students agreed/strongly agreed that TBR sessions helped their preparation for foundation year 1. 92% of medical students agreed/strongly agreed that the use of drug charts during TBR was useful for their learning. Lower proportions of students agreed/strongly agreed that TBR was a good way of learning pharmacology (44%) or would be useful for learning in other subjects (35%). Self-rated prescribing confidence increased significantly after TBR (median pre-TBR: 2, post-TBR: 5, p<0.0001).

Figure 1 The percentage of responders selecting each point on a 5-point Likert scale are shown for each of five statements about team-based revision (TBR). 1. TBR would be useful in learning other subjects. 2. TBR is a good way of learning pharmacology. 3. The use of drug charts during TBR was useful for my learning. 4. TBR sessions have helped in my preparation for foundation year 1. 5. TBR sessions have helped my preparation for the prescribing safety assessment (PSA).

Impact of TBR on students’ attitudes to teamwork

Overall, 201 students completed the pre-TBR questionnaire, and 98 students completed the post-TBR questionnaire. Eighty-six students completed both the pre- and post-TBR questionnaires. The demographics of those who completed only the pre-TBR questionnaire and those who completed both were comparable. In both groups, the majority were aged 23–24 years old (72.1% of those who completed the pre-TBR questionnaire vs 69.8% of those who completed both the pre-TBR and post-TBR questionnaires). There was a higher proportion of females in the group that completed both pre-TBR and post-TBR questionnaires (54.6% vs 49.7%), and a higher proportion of postgraduate students in the group who completed both pre-TBR and post-TBR questionnaires (15.1% vs 12.9%). For the group that completed both questionnaires, the impact of TBR on students’ attitudes to teamwork across four domains is shown in Table 2. Overall, there was a significant increase in students’ attitudes towards teamwork in the areas of Satisfaction with Team Experience (p<0.001), Team Impact on Quality of Learning (p<0.01) and Team Impact on Clinical Reasoning Ability (p<0.001) after TBR sessions. We did not see a significant change in attitude towards Professional Development after TBR sessions.

Discussion

A recent systematic literature review suggested that medical students have a general lack of preparedness, self-confidence, knowledge and skills in prescribing.14 We have shown that a short course of TBR delivered by three faculty members for 201 students can lead to a significant improvement in students’ confidence in prescribing.

It has previously been reported that students view TBL more positively once it has been embedded in the curriculum over a three-year period.8 We were interested to see how students’ perceptions of TBR would change after a two-day course, to assess its acceptability in the short term. The majority of respondents agreed that the TBR sessions helped their preparation for both the PSA and for work as newly qualified doctors. Along with the positive response to the use of drug charts, this implies that this method of interactive revision is considered helpful for exam preparation and readiness to practice. The students’ response to the usefulness of TBR for learning pharmacology was more variable. This was in keeping with the primary objective of the TBR to draw on the prescribing knowledge and skills learned across a broad range of topics by final year students rather than introducing a new topic in pharmacology. In future, it would be useful to compare how students would feel about the utility of TBL in learning pharmacology and other subjects, if they were exposed to new material through this learning method rather than using it as a tool to consolidate learning.

Extended courses of TBL have been shown to improve perceptions of teamwork in medical students.13 Interestingly, our two-day TBR course delivered similar findings, positively impacting students’ perceptions towards teamwork in all but one the assessed domains. We did not see a significant impact within the “professional development” category, suggesting that this area may require longer periods of collaborative learning to change students’ perceptions.

Our study was limited by inclusion of students from a single medical school, and a single year group. Furthermore, not all students completed both questionnaires. This may have biased the questionnaire results, not reflecting the opinions of the entire student body. It may be that TBR suits a certain cohort of students, and more work needs to be done to understand this further. Finally, another limitation of this study was the use of a scale to measure self-confidence, which had not previously been validated in this setting. As students increasingly seek active learning methods, the utility of TBR to provide a high level of engagement should be further evaluated. The PSA has also been suggested to be relevant to pharmacy trainees15 and thus TBR may also be of value in undergraduate pharmacy education.

Our study found that students responded particularly favourably to the use of drug charts during the sessions. The educational benefits of open-ended questions are well documented.16 Open-ended questions can be a useful addition to TBL,17 and our results support this. Future work should evaluate the use of online-drug charts for teaching purposes and sophisticated automated free-text marking systems.

In conclusion, our work has demonstrated TBR to be an acceptable, resource efficient method to improve medical student confidence in prescribing. Furthermore, a short course of TBR can be effective in influencing attitudes toward teamwork.
