Abstract Background The advent of electronic teaching facilities improves tutor-student communication. This study aims to explore the effectiveness of Phone-Based Audience Response System (PB-ARS), as an adjunctive pedagogy tool to enhance the retention of orthodontic information by dental students; and to explore the students’ perception of PB-ARS. Methods This cross-over clustered randomised control trial included 34 males who were in the final year of their undergraduate dental training. Participants were allocated to one of two event groups (G1 and G2) using computer-generated randomisation. Both groups simultaneously attended two different traditional lectures (L 1 and L2) a week apart. During L1, PB-ARS was used as an adjunct to conventional presentation to teach G1 participants, (PB-ARS group) while G2’s participants acted as a control group (CG), and were taught using a traditional presentation. In the second week (L2), the interventions were crossed-over. Participants from both groups completed pre- and post-lecture multiple-choice questionnaires (MCQ) to assess their short-term retention of information. Their performance in the final MCQ exam (10 weeks following L2) was tracked to assess the long-term retention of the information. Participants also completed post-lecture questionnaires to evaluate their perceptions. Results Twenty-nine and 31 participants from the CG and PB-ARS group completed this trial, respectively. Although 87.5% of students in the PB-ARS group showed an improvement in their immediate post-lecture scores compared with 79.3% for the CG, it was statistically insignificant (p = 0.465). Similarly, the intervention showed an insignificant effect on the long-term retention of the knowledge (p = 0.560). There was a mildly but favourable attitude of students towards the use of PB-ARS. However, the difference in the overall level of satisfaction between both groups was statistically insignificant (p = 0.183). Conclusion PB-ARS has a minimal and insignificant effect on the short- and long-term retention of orthodontic knowledge by male undergraduate dental students. PB-ARS was the preferred adjunct tool to conventional classroom teaching. Due to the limitations of this trial, a long-term randomised controlled trial with a larger sample size is recommended.

Abstract Background: The advent of electronic teaching facilities improved tutor-student communication. This study aims to explore the effectiveness of Phone-Based Audience Response System (PB-ARS), as an adjunctive and interactive model to traditional pedagogy, on the retention of information by undergraduate dental students and to explore the students’ perception and acceptance of PB-ARS. Methods: This cross-over clustered randomised control trial was conducted with 34 final year undergraduate dental students, who were allocated to one of two event groups (G1 and G2) using computer-generated randomisation. Both groups simultaneously attended two different traditional lectures a week apart (L 1 and L2). During L1, PB-ARS was used as an adjunct to conventional presentation to teach G1 participants (PB-ARS group). In contrast, G2’s participants acted as a control group (CG), and they were taught using the traditional presentation. In the second week (L2), the interventions were crossed. Participants from both groups completed pre- and post-lecture multiple-choice questions (MCQ) to assess short-term retention of information. They also filled post-lecture questionaries' to determine their perceptions of teaching delivery. Their performance in the final MCQ exam (10 weeks following L2) were used assess the long-term recall of the obtained knowledge. Results: 29 and 31 participants from the CG and PB-ARS group completed this trial, respectively. Although 87.5% of students in PB-ARS group showed an improvement in their post-lecture scores compared to 79.3% for CG, it was statistically insignificant. Similarly, the intervention showed an insignificant effect on the long-term retention of the knowledge.There was a mildly favourable attitude of students to the PB-ARS system; however, the difference in the overall rate of the level of satisfaction in both was statistically insignificant.Conclusion: PB-ARS system has a minimal insignificant effect on short- and long term retention of knowledge of the undergraduate dental students, though it was a slightly more preferred adjunct to conventional classroom teaching. Due to the limitation of this trial, a long-term randomised controlled trial with a larger sample size is recommended.

AbstractEnhanced follow-up is needed to improve the results of secondary preventive care in patients with established cardiovascular disease. We examined the effect of long-term, nurse-based, secondary preventive follow-up by telephone on the recurrence of cardiovascular events. Open, randomised, controlled trial with two parallel groups. Between 1 January 2010 and 31 December 2014, consecutive patients (n = 1890) admitted to hospital due to stroke, transient ischaemic attack (TIA), or acute coronary syndrome (ACS) were included. Participants were randomised (1:1) to nurse-based telephone follow-up (intervention, n = 944) or usual care (control, n = 946) and followed until 31 December 2017. The primary endpoint was a composite of stroke, myocardial infarction, cardiac revascularisation, and cardiovascular death. The individual components of the primary endpoint, TIA, and all-cause mortality were analysed as secondary endpoints. The assessment of outcome events was blinded to study group assignment. After a mean follow-up of 4.5 years, 22.7% (n = 214) of patients in the intervention group and 27.1% (n = 256) in the control group reached the primary composite endpoint (HR 0.81, 95% CI 0.68–0.97; ARR 4.4%, 95% CI 0.5–8.3). Secondary endpoints did not differ significantly between groups. Nurse-based secondary preventive follow-up by telephone reduced the recurrence of cardiovascular events during long-term follow-up.
