Prognosis of acute low back pain: design of a prospective inception cohort study

BACKGROUND: Clinical guidelines generally portray acute low back pain as a benign and self-limiting condition. However, evidence about the clinical course of acute low back pain is contradictory and the risk of subsequently developing chronic low back pain remains uncertain. There are few high quality prognosis studies and none that have measured pain, disability and return to work over a 12 month period. This study aims to provide the first estimates of the one year prognosis of acute low back pain (pain of less than 2 weeks duration) in patients consulting primary care practitioners. A secondary aim is to identify factors that are associated with the prognosis of low back pain. METHODS/DESIGN: The study is a prospective inception cohort study. Consecutive patients consulting general medical practitioners, physiotherapists and chiropractors in the Sydney metropolitan region will complete a baseline questionnaire regarding their back pain. Subsequently these patients will be followed up by telephone 6 weeks, 3 months and 12 months after the initial consultation. Patients will be considered to have recovered from the episode of back pain if they have no pain and no limitation of activity, and have returned to pre-injury work status. Life tables will be generated to determine the one year prognosis of acute low back pain. Prognostic factors will be assessed using Cox regression. DISCUSSION: This study will provide the first estimates of the one year prognosis of acute low back pain in a representative sample of primary care patients

B cell–intrinsic signaling through IL-21 receptor and STAT3 is required for establishing long-lived antibody responses in humans

Engagement of cytokine receptors by specific ligands activate Janus kinase–signal transducer and activator of transcription (STAT) signaling pathways. The exact roles of STATs in human lymphocyte behavior remain incompletely defined. Interleukin (IL)-21 activates STAT1 and STAT3 and has emerged as a potent regulator of B cell differentiation. We have studied patients with inactivating mutations in STAT1 or STAT3 to dissect their contribution to B cell function in vivo and in response to IL-21 in vitro. STAT3 mutations dramatically reduced the number of functional, antigen (Ag)-specific memory B cells and abolished the ability of IL-21 to induce naive B cells to differentiate into plasma cells (PCs). This resulted from impaired activation of the molecular machinery required for PC generation. In contrast, STAT1 deficiency had no effect on memory B cell formation in vivo or IL-21–induced immunoglobulin secretion in vitro. Thus, STAT3 plays a critical role in generating effector B cells from naive precursors in humans. STAT3-activating cytokines such as IL-21 thus underpin Ag-specific humoral immune responses and provide a mechanism for the functional antibody deficit in STAT3-deficient patients

Feedback using an ePortfolio for medicine long cases: quality not quantity

Abstract Background The evidence for the positive impact of an electronic Portfolio (ePortfolio) on feedback in medicine is mixed. An ePortfolio for medical long cases in a Graduate Medical Program was developed. The purpose of this study was to explore the perceptions of medical students and faculty of the impact of the ePortfolio on the feedback process. Methods In total, 130 Year 3 medical students, and six faculty participated in the study. This is a mixed methods study, using a combination of both quantitative and qualitative approaches. Quantitative methods were used to quantify the number of long cases performed. Qualitative methods were used to explore the relationship between quantity and quality of feedback, and provide a rich understanding of both students’ and faculty’s experience and perceptions of the ePortfolio. Results Students received a variable quantity of feedback at each of the three studied clinical schools, with an average of between 4 – 5.4 feedback episodes per student. Feedback that was constructive, specific and timely and delivered by a senior academic was important. Quantity was not an essential factor, with two episodes of detailed feedback reported to be adequate. The barriers to the use of the ePortfolio were technical aspects of the platform that interfered with student engagement. Conclusions Feedback using the ePortfolio for medical long cases is a valuable tool providing a senior clinician delivers detailed, constructive and personalized feedback in a timely fashion. The ePortfolio system needs to be user-friendly to engage students

Medical students: what educational resources are they using?

Abstract Background The number of resources available to medical students studying a degree in medicine is growing exponentially. In addition to traditional learning resources such as lectures and textbooks, students are increasingly using e-learning tools like commercially available question banks to supplement their learning. Student preference for learning resources has not been described in detail, and a better understanding of the tools perceived to be useful could provide essential information to medical educators when designing and implementing medical curricula. Methods We invited 1083 undergraduate and postgraduate medical students from two major Australian universities to complete an online survey. Questions asked students to indicate the frequency with which they use various types of resources when learning new material or when revising previous content. Results Approximately one third (32.3%, N = 350) of invited participants completed the survey, and of those who responded, the gender distribution was even with a median age of 25 years. Making written notes and reading textbooks were the most frequently utilized resources for learning new material. Online or downloaded question banks were the most frequently used resource for revision. In addition to the use of traditional learning tools, the majority of students report using a variety of e-learning tools including online teaching videos (92%, n = 322) and question banks (90.6%, n = 317). Conclusion Despite the trend towards e-learning, traditional resources like attendance at face-to-face lectures remain the most popular for learning new material. The increasing use of question banks raises potential issues of poor alignment to medical school curricula. With the advantages of exam technique practice, time efficiency and multiplatform availability, their popularity is likely to continue. Evaluation of existing question banks is required to facilitate appropriate integration into the curricula, with equitable access for all students

Team-based learning replaces problem-based learning at a large medical school

Absract Background With increased student numbers in the Sydney Medical Program, and concerns regarding standardisation across cohorts, student satisfaction of the problem-based learning (PBL) model had decreased in recent years. In 2017, Team-based learning (TBL) replaced PBL in Years 1 and 2 of the medical program. This study sought to explore students’ perceptions of their experience of TBL, and to consider resource implications. Methods In 2017, Years 1 and 2 medical students (n = 625) participated in weekly TBL sessions, with approximately 60 students per class, consisting of 11 teams of five or six students. Each class was facilitated by a consultant, a basic scientist and a medical registrar. Prior to each class, students were given pre-work, and completed an online Individual Readiness Assurance Test (IRAT). During face-to-face class, students completed the Team Readiness Assurance Test (TRAT), and received feedback with clarification from facilitators, followed by clinical problem-solving activities. Student feedback was collected by questionnaire, using closed and open-ended items. Data were analysed using descriptive statistics and thematic analysis. Results In total, 232/275 (84%) Year 1 and 258/350 (74%) Year 2 students responded to the questionnaire. Students found positive aspects of TBL included the small group dynamics, intra- and inter-team discussions, interactions with facilitators, provision of clinical contexts by clinicians, and the readiness assurance process. Suggested improvements included: better alignment of pre-reading tasks, shorter class time, increased opportunity for clinical reasoning, and additional feedback on the mechanistic flowchart. Resource efficiencies were identified, such as a reduction in the number of teaching sessions and required facilitators, and the ability to provide each classroom with clinical expertise. Conclusions Our findings demonstrate that TBL, as a replacement for PBL in Years 1 and 2 of the medical curriculum, provided a standardised approach to small group learning on a large scale, and also provided resource efficiencies. Students perceived benefits related to the active learning strategy of TBL that encourage individual learning, consolidation of knowledge, retrieval practice, peer discussion and feedback. However, improvements are needed in terms of better alignment of pre-reading tasks with the TBL patient case, and greater facilitator interaction during the problem-solving activities. Additionally, consideration should be given to reducing class time, and providing TRAT scores. </jats:sec

Interprofessional team-based learning (TBL): how do students engage?

Abstract Background Although challenging to integrate within university curricula, evidence suggests that interprofessional education (IPE) positively impacts communication and teamwork skills in the workplace. The nature of Team-based learning (TBL) lends itself to interprofessional education, with the capacity to foster a culture of collaboration among health professional students. Our study was designed to pilot an interprofessional ‘back pain’ TBL module for physiotherapy and medical students, and to explore their experience of the TBL process, using the conceptual framework of ‘knowledge reconsolidation’ to discuss our finding. Methods Three hundred and eleven students participated in the TBL session: 222/277 (80%) of Year 1 medical students and 89/89 (100%) of Year 2 physiotherapy students. Students completed one interprofessional Musculoskeletal Sciences TBL session on the topic of ‘back pain’. A questionnaire including closed and open-ended items, was distributed to students immediately following completion of the TBL session. Descriptive statistics were used to analyse the quantitative data. Thematic analysis was used to code and categorise qualitative data into themes. Pre-class quiz scores were compared between the groups using a one-way between groups Analysis of Variance (ANOVA) test with Tukeys Post Hoc test. Results In total, 117/311 (38%) of participants completed the questionnaire. Both medicine and physiotherapy students appreciated the opportunity to learn about the curriculum of another healthcare discipline, and their scope of practice; gain multiple perspectives on a patient case from different disciplines; and recognised the importance of multidisciplinary teams in patient care. Students felt having an interprofessional team of facilitators who provided immediate feedback helped to consolidate student learning and promoted clinical reasoning. An analysis of variance revealed no difference between Physiotherapy and Medical students’ pre-class quiz scores. Conclusion Our study demonstrated that the small group and task-focused characteristics of TBL provided a student-centred teaching strategy to support the achievement of interprofessional learning goals. Students valued their interactions with other students from a different professional degree, the opportunity to problem solve together, and learn different perspectives on a patient case. The pre-class quiz results demonstrate that both groups of students had a comparative level of prior knowledge to be able to work together on the in-class activities. </jats:sec

Team-based learning (TBL) in the medical curriculum: better than PBL?

Abstract Background Internationally, medical schools have long used a variety of approaches to develop hybrid Problem based learning (PBL) curricula. However, Team-based learning (TBL), has gained recent popularity in medical education. TBL maintains the advantages of small group teaching and learning, but in contrast to Problem-based learning (PBL), does not require large numbers of tutors. In 2016, TBL was introduced to Year 1 of the Sydney Medical Program (SMP).This study sought to compare students’ perceptions of using TBL in place of PBL. Methods Year 1 students (n = 169) completed three PBL and three TBL sessions during one of the following teaching blocks: Musculoskeletal (n = 56), Respiratory (n = 59) or Cardiovascular (n = 54). Student feedback following completion of each block of teaching was collected by questionnaire, using closed and open ended items. Data were analysed using descriptive statistics and thematic analysis. Results In total, 144/169 (85%) of participants completed a questionnaire regarding PBL, and 152/169 (90%) completed a similar questionnaire regarding TBL. The students found positive aspects of their TBL experience to include the smaller group size, the use of readiness assurance tests, immediate feedback from senior clinicians, and time efficiency. In PBL, students reported that variable expertise of tutors; limited direction; and large group size hindered their learning. Conclusions Overwhelmingly, students preferred TBL over PBL, as the optimal teaching strategy. Students found the structure and format of the TBL sessions more conducive to learning, engagement and participation than PBL sessions. Although the use of TBL required an instructional approach, needing direction from the tutor, it remained student-centred, generating a range of positive outcomes. Study results provide confidence to change from PBL to TBL within Year 1 and Year 2 of the SMP in 2017
