The paradoxical influence of the COVID-19 lockdown period on different types of preterm births in Alberta: a provincial study.

Objectives: The objective of this study was to determine if the COVID-19 pandemic impacted different types of preterm birth rates in Alberta, Canada. Methods: A population-based, retrospective, cohort study was conducted from March 15, 2015 to December 31, 2020 using provincial data. The primary exposure was the COVID-19 lockdown period, and the primary outcome was the incidence of preterm birth (<37 weeks gestational age). Multivariable analyses in the complete lockdown and overall lockdown (partial and complete lockdown) periods were performed to test the association between the year of birth and preterm birth status and were adjusted for various independent variables. Preterm birth status was adjusted for various confounding factors. Results: Following the analysis of n = 41,187 mothers and their singleton infants, we found that the lockdown due to COVID-19 had no impact in reducing the overall preterm birth rate. However, a paradoxical influence was observed with an increase of extremely low preterm births in the overall lockdown period, and a decrease in moderate preterm births during the complete lockdown period. Conclusions: The results of this study demonstrated that there was a decrease in moderate and increase in extremely low preterm birth rates as a result of the COVID-19 lockdown. However, the COVID-19 lockdown did not impact the very preterm and late preterm birth rate in Alberta.

Targeted Neonatal Echocardiography Performed by Nurse Practitioners in the NICU: Attitudes and Perceptions of the Healthcare Team.

BACKGROUND: Targeted neonatal echocardiography (TNE) and hemodynamic consultation have typically been performed by physicians. The Stollery Children's Hospital neonatal intensive care unit (NICU) expanded their TNE training program to include neonatal nurse practitioners (NNPs), the first in North America. PURPOSE: This study examines the thoughts and perceptions of clinicians about the incorporation of NNPs providing TNE and hemodynamic consultation and investigates key facilitators and challenges for consideration when planning future training, expansion of service in Edmonton, or beyond. METHODS: In this descriptive study using qualitative methodology, purposive sampling was used to invite NICU clinicians to participate. Using a semistructured topic guide, a focus group and 2 individual interviews were conducted. RESULTS: Participants were supportive of NNPs. Advantages included increased access to service, acquisition and retention of skills, provision of patient-centered care, and leveraged interpersonal relationships in the decision-making process. Key aspects of program expansion included climate and culture of the NICU, presence of adequate patient volume, and resources to support training. IMPLICATIONS FOR PRACTICE AND RESEARCH: Support across disciplines and the collaborative working nature of the NICU are key factors in the success of the program's development and implementation. Benefits of having NNPs on the TNE team were clearly expressed. Benefits to the health system included rapid access to hemodynamic information allowing for care based on specific pathophysiology and additional local capacity to perform TNE and reducing demand on other trained providers. Additional research could consider parental views of NNPs performing TNE and hemodynamic consultation as well as the accuracy of diagnosis between the NNPs and physician group.

How a Team Effectiveness Approach to Health Systems Science Can Illuminate Undergraduate Medical Education Outcomes.

ABSTRACT: Health care delivery requires physicians to operate in teams to successfully navigate complexity in caring for patients and communities. The importance of training physicians early in core concepts of working in teams (i.e., "teaming") has long been established. Over the past decade, however, little evidence of team effectiveness training for medical students has been available. The recent introduction of health systems science as a third pillar of medical education provides an opportunity to teach and prepare students to work in teams and achieve related core competencies across the medical education continuum and health care delivery settings. Although educators and health care system leaders have emphasized the teaching and learning of team-based care, conceptual models and evidence that inform effective teaming within all aspects of undergraduate medical education (including classroom, clinical, and community settings) are needed to advance the science regarding learning and working in teams. Anchoring teaming through the core foundational theory of team effectiveness and its operational components could catalyze the empirical study of medical student teams, uncover modifiable factors that lead to the evidence for improved student learning, and improve the link among competency-based assessments between undergraduate medical education and graduate medical education. In this article, authors articulate several implications for medical schools through 5 conceptual areas: admissions, the design and teaching of team effectiveness in health systems science curricula, the related competency-based assessments, and course and program evaluations. The authors then discuss the relevance of the measurable components and intended outcomes to team effectiveness in undergraduate medical education as critical to successfully prepare students for teaming in clerkships and eventually residency and clinical practice.

Clinical Assessment Specialists: A New Faculty Role to Improve Clerkship Assessment.

INTRODUCTION: Ambulatory clerkships, including longitudinal integrated clerkships (LICs), face challenges to assessment, including time pressure and clinical demands on preceptors. High-quality clinical assessment is critical to implementing competency-based medical education, generating valid grades, and supporting learning. This importance is further heightened with the new pass/fail scoring for US Medical Licensing Exam Step 1, discontinuation of US Medical Licensing Exam Step 2 Clinical Skills, and the growing concern for bias in assessment. METHODS: The Kaiser Permanente Bernard J. Tyson School of Medicine's LIC spans the first 2 years with 50 students per class. In 2021-2022, the authors created a new faculty role, the clinical assessment specialist (CASp). CASps are highly trained clinical teachers who directly observe clerkship students in the ambulatory setting, provide feedback, and complete competency-based assessment forms. RESULTS: CASps completed 186 assessments of first-year (Y1) LIC students and 333 assessments of second-year (Y2) LIC students. Y2 students achieved average higher milestones and were rated as requiring less supervision compared to Y1 students. Y1 students rated CASps more favorably than Y2 students. Preceptors rated the contribution of CASps similarly across both years. Clerkship directors described benefits including identification of at-risk students and value of augmenting preceptor assessments. DISCUSSION: The CASp role may offer an innovative way to generate valid assessment of student performance, offset clinical pressures faced by preceptors, identify at-risk students, and mitigate bias, especially in an LIC. Future studies may examine assessment validity, including use in summative assessment. CONCLUSION: CASps are an innovative approach to clinical clerkship assessment.

Acetaminophen versus indomethacin for patent ductus arteriosus management in premature infants: systematic review and meta-analysis of randomized controlled trials.

Objectives: Acetaminophen has gained interest in the neonatal community for its use in the management of hemodynamically significant patent ductus arteriosus (HsPDA) in preterm infants. We conducted a systematic review of randomized controlled trials (RCTs) comparing the efficacy and safety of acetaminophen with indomethacin for the management of HsPDA in preterm infants. Methods: We searched PROSPERO, OVID Medline, OVID EMBASE, Wiley Cochrane Library (CDSR and Central), EBSCO CINAHL, and SCOPUS from inception to June 15, 2021. Bibliographies of identified studies were searched for additional references. Data were analyzed with Review Manager (RevMan) Version 5.3. Results: Four RCTs were identified, enrolling a total of 380 subjects. There was no difference between the interventions for the outcome of PDA closure after one course (RR 1.04 [95% CIs: 0.84, 1.29], P-value 0.70) or after two courses of treatment (RR 1.01 [95% CIs: 0.92, 1.12], P-value 0.77); and for the outcome of PDA ligation (RR 1.56 [95% CIs: 0.48, 5.12], P-value 0.46). However, patients who received acetaminophen had lower rates of necrotizing enterocolitis (RR 0.37 [95% CIs: 0.14, 0.95], P-value 0.04). There were no significant differences noted in the other clinical outcomes, that is, intraventricular hemorrhage, bronchopulmonary dysplasia, retinopathy of prematurity requiring treatment, and death. Two studies noted significant post-treatment elevation of serum creatinine and blood urea with indomethacin, as compared to none with acetaminophen use. Conclusions: Acetaminophen has comparable efficacy to indomethacin for the outcome of HsPDA closure, with a better safety profile, that is, lesser rates of necrotizing enterocolitis and post-treatment azotemia noted with its use.

Point-of-care ultrasound (POCUS) protocol for systematic assessment of the crashing neonate-expert consensus statement of the international crashing neonate working group.

Sudden unexpected clinical deterioration or cardiorespiratory instability is common in neonates and is often referred as a "crashing" neonate. The established resuscitation guidelines provide an excellent framework to stabilize and evaluate these infants, but it is primarily based upon clinical assessment only. However, clinical assessment in sick neonates is limited in identifying underlying pathophysiology. The Crashing Neonate Protocol (CNP), utilizing point-of-care ultrasound (POCUS), is specifically designed for use in neonatal emergencies. It can be applied both in term and pre-term neonates in the neonatal intensive care unit (NICU). The proposed protocol involves a stepwise systematic assessment with basic ultrasound views which can be easily learnt and reproduced with focused structured training on the use of portable ultrasonography (similar to the FAST and BLUE protocols in adult clinical practice). We conducted a literature review of the evidence-based use of POCUS in neonatal practice. We then applied stepwise voting process with a modified DELPHI strategy (electronic voting) utilizing an international expert group to prioritize recommendations. We also conducted an international survey among a group of neonatologists practicing POCUS. The lead expert authors identified a specific list of recommendations to be included in the proposed CNP. This protocol involves pre-defined steps focused on identifying the underlying etiology of clinical instability and assessing the response to intervention.Conclusion: To conclude, the newly proposed POCUS-based CNP should be used as an adjunct to the current recommendations for neonatal resuscitation and not replace them, especially in infants unresponsive to standard resuscitation steps, or where the underlying cause of deterioration remains unclear. What is known? • Point-of-care ultrasound (POCUS) is helpful in evaluation of the underlying pathophysiologic mechanisms in sick infants. What is new? • The Crashing Neonate Protocol (CNP) is proposed as an adjunct to the current recommendations for neonatal resuscitation, with pre-defined steps focused on gaining information regarding the underlying pathophysiology in unexplained "crashing" neonates. • The proposed CNP can help in targeting specific and early therapy based upon the underlying pathophysiology, and it allows assessment of the response to intervention(s) in a timely fashion.

What Are the Minimal Feeds Required for Starting Enteral Ibuprofen in Preterm Infants with PDA?

Ibuprofen is commonly used for the treatment of hemodynamically significant patent ductus arteriosus (PDA) in preterm infants. It seems that the oral formulation incurs a higher closure rate and has a better safety profile in preterm infants born > 26 weeks' gestation. There is no consensus across Canadian centers regarding the minimum volume of enteral feeds required prior to starting ibuprofen for the treatment of patent ductus arteriosus, and the current practice is comfort-based depending on the centre and the local prevalence of neonatal morbidities.

Multimodal Assessment of Systemic Blood Flow in Infants.

The assessment of systemic blood flow is a complex and comprehensive process with clinical, laboratory, and technological components. Despite recent advancements in technology, there is no perfect bedside tool to quantify systemic blood flow in infants that can be used for clinical decision making. Each option has its own merits and limitations, and evidence on the reliability of these physiology-based assessment processes is evolving. This article provides an extensive review of the interpretation and limitations of methods to assess systemic blood flow in infants, highlighting the importance of a comprehensive and multimodal approach in this population.

Different approaches for patent ductus arteriosus in premature infants using acetaminophen.

BACKGROUND: Acetaminophen use for pharmacological treatment of hemodynamically significant patent ductus arteriosus (hsPDA) in preterm infants is becoming more popular with emerging evidence that it is effective as well as safe alternative for other agents used to close hsPDA. DATA SOURCES: We performed a narrative review of literature about pharmacological treatment of PDA using acetaminophen. RESULTS: Acetaminophen was used as a prophylaxis, symptomatic, targeted, and a rescue approach. CONCLUSIONS: It appears that acetaminophen could be used in different approaches to close the hsPDA. Long-term outcomes of acetaminophen exposure early in life still lack certainty.

Pulmonary artery dopplers for early prediction of risk for bronchopulmonary dysplasia in extremely low birth weight babies.

OBJECTIVE: The early abnormal pulmonary vasoreactivity observed in babies at risk of Bronchopulmonary dysplasia (BPD) increases the pulmonary vascular resistance. This can be assessed non-invasively using Time to Peak Velocity:Right Ventricular Ejection Time ratio (TPV:RVET) measured from pulmonary artery Doppler waveform obtained using echocardiogram. We postulate that screening for this early can predict BPD in this cohort. The objective of the study was to determine the utility of TPV:RVET in early prediction of BPD in Extremely Low Birth Weight (ELBW) babies born less than 1250grams Birth Weight. METHODS: This was a single-center retrospective cohort study of ELBW babies born<29 weeks over 4 year period who had echocardiogram between 7-21 days of life. TPV:RVET ratio was measured from pulmonary artery Doppler waveform obtained using echocardiogram. The main outcome was BPD at 36 weeks corrected gestation. The predictive ability of TPV:RVET (cut off 0.34) for subsequent development of BPD was analyzed using ROC. RESULTS: Of 589 ELBW<29 weeks, 207 babies were eligible. BPD was found in 60.4%. The TPV:RVET at 0.34 had sensitivity 76.8% (95%CI 68.4-83.9), specificity 85.4% (95%CI 75.8-92.2), positive predictive value 88.9% (95%CI 81.4-94.1), negative predictive value 70.7% (95%CI 60.7-79), and ROC area 0.811 (95%CI 0.757-0.864). Odds ratio of having BPD for TPV:RVET at 0.34 was 19.9 (95%CI 8.19-48.34) and increased by 1.07 (95%CI 1.05-1.09) with every additional days of mechanical ventilation. TPV:RVET ratio had 92.75% inter-observer agreement with kappa 0.83. CONCLUSION: TPV:RVET ratio is a good and reliable early screening tool for subsequent development of BPD in ELBW babies with substantial inter-observer agreement.

Influence of extreme prematurity and bronchopulmonary dysplasia on cardiac function.

OBJECTIVE: Prematurity and bronchopulmonary dysplasia (BPD) are associated with poorly understood abnormalities of ventricular function. We therefore comprehensively compared biventricular function in infants with and without BPD. METHODS: Prospective observational study in extremely preterm infants with (n = 20) and without (n = 38) BPD using conventional and advanced echocardiography at 28 days (T1) and near-term (T2). RESULTS: Infants with BPD had lower birth gestational age (26.7±1.9 vs 27.4±1.1 weeks, p = 0.047) and weight (884±207 vs 1108±190 g, p = 0.0001). BPD was associated with larger right ventricles (RV) and reduced RV systolic strain rate at T1 and pulmonary hypertensive indicators at T2 (pulmonary artery acceleration time BPD 51±17 vs no BPD 63±12 ms, p = 0.017). At T1/T2, infants with BPD had lower RV tissue Doppler velocities (e', a' and s) and higher E/e' ratios (T1: BPD 10.4±2.4 vs no BPD 6.2±3.1 cm/sec, p = 0.001; T2: BPD 8.0±3.1 vs no BPD 5.6±2.6 cm/sec, p = 0.02), altered LV diastolic function (apical circumferential T1 early diastolic strain rate BPD 2.8±0.8 vs no BPD 3.6±1.0 /sec, p = 0.04; T2 late diastolic strain rate, BPD 2.29 ± 0.99 vs no BPD 1.67±0.84 /sec, p = 0.03) and LV rotational mechanics (T1: twist rate BPD 90±16 vs no BPD 130±48 deg/sec, p = 0.008; untwist rate (UTR) BPD -69±90 vs no BPD -147±68 deg/sec, p = 0.008; torsion BPD 2.78±0.56 vs no BPD 4.48±1.74 deg/cm, p = 0.009; and T2: UTR BPD -132±69 vs no BPD -179±57 deg/sec, p = 0.013). CONCLUSION: BPD is associated with altered RV diastolic function that persists near term, with elevated pulmonary vascular resistance, and with persistent alterations in LV apical strain rate and rotational mechanics.

Relative effectiveness and safety of pharmacotherapeutic agents for patent ductus arteriosus (PDA) in preterm infants: a protocol for a multicentre comparative effectiveness study (CANRxPDA).

INTRODUCTION: Patent ductus arteriosus (PDA) is the most common cardiovascular problem that develops in preterm infants and evidence regarding the best treatment approach is lacking. Currently available medical options to treat a PDA include indomethacin, ibuprofen or acetaminophen. Wide variation exists in PDA treatment practices across Canada. In view of this large practice variation across Canadian neonatal intensive care units (NICUs), we plan to conduct a comparative effectiveness study of the different pharmacotherapeutic agents used to treat the PDA in preterm infants. METHODS AND ANALYSIS: A multicentre prospective observational comparative-effectiveness research study of extremely preterm infants born <29 weeks gestational age with an echocardiography confirmed PDA will be conducted. All participating sites will self-select and adhere to one of the following primary pharmacotherapy protocols for all preterm babies who are deemed to require treatment.Standard dose ibuprofen (10 mg/kg followed by two doses of 5 mg/kg at 24 hours intervals) irrespective of postnatal age (oral/intravenous).Adjustable dose ibuprofen (oral/intravenous) (10 mg/kg followed by two doses of 5 mg/kg at 24 hours intervals if treated within the first 7 days after birth. Higher doses of ibuprofen up to 20 mg/kg followed by two doses of 10 mg/kg at 24 hours intervals if treated after the postnatal age cut-off for lower dose as per the local centre policy).Acetaminophen (oral/intravenous) (15 mg/kg every 6 hours) for 3-7 days.Intravenous indomethacin (0.1-0.3 mg/kg intravenous every 12-24 hours for a total of three doses). OUTCOMES: The primary outcome is failure of primary pharmacotherapy (defined as need for further medical and/or surgical/interventional treatment following an initial course of pharmacotherapy). The secondary outcomes include components of the primary outcome as well as clinical outcomes related to response to treatment or adverse effects of treatment. SITES AND SAMPLE SIZE: The study will be conducted in 22 NICUs across Canada with an anticipated enrollment of 1350 extremely preterm infants over 3 years. ANALYSIS: To examine the relative effectiveness of the four treatment strategies, the primary outcome will be compared pairwise between the treatment groups using χ2 test. Secondary outcomes will be compared pairwise between the treatment groups using χ2 test, Student's t-test or Wilcoxon rank sum test as appropriate. To further examine differences in the primary and secondary outcomes between the four groups, multiple logistic or linear regression models will be applied for each outcome on the treatment groups, adjusted for potential confounders using generalised estimating equations to account for within-unit-clustering. As a sensitivity analysis, the difference in the primary and secondary outcomes between the treatment groups will also be examined using propensity score method with inverse probability weighting approach. ETHICS AND DISSEMINATION: The study has been approved by the IWK Research Ethics Board (#1025627) as well as the respective institutional review boards of the participating centres. TRIAL REGISTRATION NUMBER: NCT04347720.

Evaluating Core Clerkships: Lessons Learned From Implementing a Student-Driven Feedback System for Clinical Curricula.

PROBLEM: Medical schools have implemented various ways to engage students in improving medical curricula. These systems, however, usually focus on the preclerkship curriculum, perhaps because medical students move through this phase of medical education synchronously, making it easier to collect student input. In contrast, clerkship and postclerkship curricula often lack similar levels of student engagement in program evaluation. APPROACH: To increase communication among students, faculty, and administration during the clinical years of medical education, the Student Curricular Board (SCB) at the University of Illinois College of Medicine's Chicago campus (UICOM-Chicago) developed a student-driven feedback model in 2016 that aimed to parallel the system previously implemented in the preclerkship years. Interested fourth-year students were selected by their peers to represent individual core clerkships, and they communicated regularly with clerkship directors about concerns from current clerkship students. Third-year students applied and were selected to represent their cohort of peers moving through clerkship tracks. Proposed changes and improvements were tracked via novel, student-driven SOAP-Education (SOAP-Ed) progress notes written throughout the academic year. OUTCOMES: In response to a program evaluation survey conducted after implementation of this pilot, third-year students said they felt that their feedback was taken seriously by faculty and administration. Furthermore, student feedback led to meaningful changes in core clerkship curricula and in the system used to gather clerkship feedback. Clerkship directors expressed appreciation for this partnership, and students said they gained valuable leadership experience and knowledge of curricular development. NEXT STEPS: Current SCB members and curricular leadership plan to assess student and faculty perceptions of this system and its efficacy and work toward expansion to all UICOM campuses. Lessons learned from this student-driven model of feedback in third-year core clerkships will likely add to the conversation on how to better engage medical students as active stakeholders in their own education.

Medical Students' Views on Implementing the Core EPAs: Recommendations From Student Leaders at the Core EPAs Pilot Institutions.

In 2014, the Association of American Medical Colleges recruited 10 institutions across the United States to pilot the 13 Core Entrustable Professional Activities for Entering Residency (Core EPAs). The goal was to establish a competency-based framework to prepare graduating medical students for the transition to residency. Within the Core EPAs pilot, medical students play an influential role in the development and implementation of EPA-related curricula. Student engagement was a priority for the Core EPAs institutions given students' roles as the end users of the curriculum, thus they may offer valuable insight into its design and implementation. Here, the authors provide the perspective of medical students who serve as leaders in the Core EPAs pilot at their respective institutions. They describe student leadership models across the pilot institutions as well as 6 key challenges to implementation of the Core EPAs: (1) How and when should the Core EPAs be introduced? (2) Who is responsible for driving the assessment process? (3) What feedback mechanisms are required? (4) What systems are required for advising, mentoring, or coaching students? (5) Should EPA performance contribute to students' grades? and (6) Should entrustment decisions be tied to graduation requirements? Using a polarity management framework to address each challenge, the authors describe inherent tensions, approaches used by the Core EPAs pilot institutions, and student-centered recommendations for resolving each tension. By sharing the experiences and perspectives of students engaged in the Core EPAs pilot, the authors hope to inform implementation of EPA-oriented assessment practices and feedback across institutions in the United States.

Developing an Entrustment Process: Insights from the AAMC CoreEPA Pilot.

One of the main goals of the CoreEPA pilot has been to determine the feasibility of developing a process to make summative entrustment decisions regarding entrustable professional activities (EPAs). Five years into the pilot, we report results of a research study we conducted to explore approaches to the entrustment process undertaken by our ten participating schools. We sought to identify the choices that participating schools made regarding the entrustment process and why these decisions were made. We are sharing these results, highlighting ongoing challenges that were identified with the intent of helping other medical schools that are moving toward EPA-based assessment. We conducted semi-structured interviews with representatives of all 10 medical schools in the CoreEPA pilot to understand their choices in designing the entrustment process. Additional information was obtained through follow-up communication to ensure completeness and accuracy of the findings. Several common themes are described. Our results indicate that, while approaches to the entrustment process vary considerably, all schools demonstrated consistent adherence to the guiding principles of the pilot. Several common barriers to the entrustment process emerged, and there was a consensus that more experience is needed with the process before consequential entrustment decisions can be made. The CoreEPA pilot schools continue to address challenges identified in implementing entrustment processes and making entrustment decisions for our students graduating in the Class of 2020.

Empowering medical students as agents of curricular change: a value-added approach to student engagement in medical education.

One area in which medical students can add significant value is medical education, and involving them as key stakeholders in their education can have a profound impact on students and the institutions that serve them. However, detailed descriptions of the structure, implementation and quality of programs facilitating student engagement are lacking. We describe the structure of a novel student engagement program at the University of Illinois College of Medicine-Chicago (UICOM-Chicago) known as the Student Curricular Board (SCB). We surveyed 563 medical students across all levels of training at our institution in order to examine the impact of this program, including its strengths and potential areas of improvement. The SCB serves as a highly structured and collaborative student group that has far-reaching involvement from course-level program evaluation to longitudinal curriculum design. Medical students overwhelmingly valued opportunities to be involved in their curriculum. Students with the greatest exposure to the SCB were more aware of specific program initiatives and expressed increased interest in academic medicine as a career. By highlighting this innovative student engagement program, we aim to share best practices for a highly structured, value-added approach to medical student engagement in medical education that is applicable to other medical schools and student leaders.

Can Nonclinician Raters Be Trained to Assess Clinical Reasoning in Postencounter Patient Notes?

PURPOSE: Clinical reasoning is often assessed through patient notes (PNs) following standardized patient (SP) encounters. While nonclinicians can score PNs using analytic tools such as checklists, these do not sufficiently encompass the holistic judgments of clinician faculty. To better model faculty judgments, the authors developed checklists with faculty-specified scoring formulas embedded in spreadsheets and studied the resulting interrater reliability (IRR) of nonclinician raters (SPs and medics) and student pass/fail status. METHOD: In Study 1, nonclinician and faculty raters rescored PNs of 55 third-year medical students across 5 cases of the 2017 Graduation Competency Examination (GCE) to determine IRR. In Study 2, nonclinician raters scored all notes of the 5-case 2018 GCE (178 students). Faculty rescored all notes of failing students and could modify formula-derived scores if faculty felt appropriate. Faculty also rescored and corrected scores of additional notes for a total of 90 notes (3 cases, including failing notes). RESULTS: Mean overall percent exact agreement between nonclinician and faculty ratings was 87% (weighted kappa, 0.86) and 83% (weighted kappa, 0.88) for Study 1 and Study 2, respectively. SP and medic IRRs did not differ significantly. Four students failed the note section in 2018; 3 passed after faculty corrections. Few corrections were made to nonfailing students' notes. CONCLUSIONS: Nonclinician PN raters using checklists and scoring rules may provide a feasible alternative to faculty raters for low-stakes assessments and for the bulk of well-performing students. Faculty effort can be targeted strategically at rescoring notes of low-performing students and providing more detailed feedback.

Self-Directed and Lifelong Learning: the 5th "S" for TBL™ Application Exercises?

This paper describes a pilot of an innovation to TBL™ as a means to add a fifth "S", self-directed learning (SDL) and life-long learning (LLL), to the 4S application exercise framework. It is important for TBL™ to explicitly address SDL and LLL to enhance student learning and meet accreditation standards.

Development and Evaluation of a Student-Initiated Test Preparation Program for the USMLE Step 1 Examination.

PROBLEM: Studies have documented performance on the United States Medical Licensing Examination® (USMLE) Step 1 exam as an important factor that residency program directors consider when deciding which applicants to interview and rank. Therefore, success on this exam, though only one aspect of applicant evaluation, is important in determining future career prospects for medical students. Unfortunately, mean test scores at the University of Illinois College of Medicine at Chicago (UIC) have historically been below the national average. INTERVENTION: This retrospective and quasi-experimental mixed-methods study describes the development, evaluation, and effects of a student-initiated USMLE Step 1 preparatory program at UIC. The program provided second year students with First Aid for the USMLE Step 1 at the beginning of the academic year, as well as a six month subscription to the USMLE World question bank midyear. In addition, optional peer review sessions covering basic sciences and organ systems were taught by high-performing upperclassmen. The goals of the program were to raise mean USMLE Step 1 exam scores and increase the percentage of students passing the exam on their first time. CONTEXT: The program premiered during the 2012-13 academic year. Data from this cohort as well as four others (N = 830; 2010-2014 examinees) were gathered. Performances between preintervention (2010-12 examinees) and postintervention (2013-14 examinees) cohorts of students were compared. Focus groups and interviews with staff and students were conducted, recorded, and analyzed to investigate the impact that the program had on student interactions and perceptions of the learning environment. OUTCOME: There was a significant difference in exam performance pre- versus postintervention, with average USMLE Step 1 scores improving by 8.82 points following the implementation of the student-initiated program, t(5.61) = 828, p < .001. The average first-attempt pass rate also increased significantly by 8%, χ2(1) = 23.13, p < .001. Taking age, sex, Medical College Admission Test® scores, and undergraduate grade point average into account, students who participated in the program scored 6.57 points higher than students who did not participate in the program (R2 = 0.3), F(5, 886) = 76.71, p < .01, and had higher odds of passing USMLE Step 1 (odds ratio = 3.08, SE = 1.07, p < .01). Students and staff commented on the sense of community and empowerment the program created as well as the unique student-driven nature of the program. LESSONS LEARNED: This study demonstrates the efficacy of a student-initiated curriculum and provides guidance for development and implementation of examination preparatory efforts at other institutions.
