ABSTRACT

PURPOSE: The purpose of this study was to explore the effect of a lingual resistance training protocol on the swallowing function of an individual presenting with dysphagia and reduced tongue pressures following a supratentorial ischemic stroke. METHODS: A study involving a lingual resistance training protocol with videofluoroscopy to measure outcomes comparing different parameters to ASPEKT normative reference values at three timepoints: baseline (VFSS A), following a 4-week lead-in period to control for spontaneous recovery (VFSS B), and at the 8-week endpoint of treatment (VFSS C). The study was interrupted due to the COVID-19 pandemic after 1 participant enrollment and is presented as single case study. RESULTS: Isometric tongue pressures: Following the 4-week lead-in, a decline in maximum isometric anterior tongue pressure (MAIP) and regular effort saliva swallow pressures (RESS) was noted, however there was no change in maximum posterior isometric tongue pressures (MPIP). Isometric tongue pressures improved post-treatment, with increases in MAIP, MPIP, and to a lesser degree RESS. Swallowing Function: Impairments in swallowing safety continued between the baseline VFSS A (Penetration-Aspiration Scale score [PAS]=8) and lead-in VFSS B (PAS=5). Swallowing safety improved following the intervention, with PAS scores = 1 at the endpoint VFSS C. Pixel-based measures of swallowing efficiency revealed a reduced frequency of post-swallow total pharyngeal reside following the treatment. Improvements were found in two other swallowing parameters, laryngeal vestibule closure integrity and pharyngeal area at maximum pharyngeal constriction, at the endpoint VFSS. CONCLUSION: These pilot data suggest improvements in some swallowing parameters as an outcome of intervention.

ABSTRACT

Postgraduate medical education is an essential societal enterprise that prepares highly skilled physicians for the health workforce. In recent years, PGME systems have been criticized worldwide for problems with variable graduate abilities, concerns about patient safety, and issues with teaching and assessment methods. In response, competency based medical education approaches, with an emphasis on graduate outcomes, have been proposed as the direction for 21st century health profession education. However, there are few published models of large-scale implementation of these approaches. We describe the rationale and design for a national, time-variable competency-based multi-specialty system for postgraduate medical education called Competence by Design. Fourteen innovations were bundled to create this new system, using the Van Melle Core Components of competency based medical education as the basis for the transformation. The successful execution of this transformational training system shows competency based medical education can be implemented at scale. The lessons learned in the early implementation of Competence by Design can inform competency based medical education innovation efforts across professions worldwide.

ABSTRACT

Traditional approaches to assessment in health professions education systems, which have generally focused on the summative function of assessment through the development and episodic use of individual high-stakes examinations, may no longer be appropriate in an era of competency based medical education. Contemporary assessment programs should not only ensure collection of high-quality performance data to support robust decision-making on learners' achievement and competence development but also facilitate the provision of meaningful feedback to learners to support reflective practice and performance improvement. Programmatic assessment is a specific approach to designing assessment systems through the intentional selection and combination of a variety of assessment methods and activities embedded within an educational framework to simultaneously optimize the decision-making and learning function of assessment. It is a core component of competency based medical education and is aligned with the goals of promoting assessment for learning and coaching learners to achieve predefined levels of competence. In Canada, postgraduate specialist medical education has undergone a transformative change to a competency based model centred around entrustable professional activities (EPAs). In this paper, we describe and reflect on the large scale, national implementation of a program of assessment model designed to guide learning and ensure that robust data is collected to support defensible decisions about EPA achievement and progress through training. Reflecting on the design and implications of this assessment system may help others who want to incorporate a competency based approach in their own country.

ABSTRACT

Coaching is an increasingly popular means to provide individualized, learner-centered, developmental guidance to trainees in competency based medical education (CBME) curricula. Aligned with CBME's core components, coaching can assist in leveraging the full potential of this educational approach. With its focus on growth and improvement, coaching helps trainees develop clinical acumen and self-regulated learning skills. Developing a shared mental model for coaching in the medical education context is crucial to facilitate integration and subsequent evaluation of success. This paper describes the Royal College of Physicians and Surgeons of Canada's coaching model, one that is theory based, evidence informed, principle driven and iteratively and developed by a multidisciplinary team. The coaching model was specifically designed, fit for purpose to the postgraduate medical education (PGME) context and implemented as part of Competence by Design (CBD), a new competency based PGME program. This coaching model differentiates two coaching roles, which reflect different contexts in which postgraduate trainees learn and develop skills. Both roles are supported by the RX-OCR process: developing Relationship/Rapport, setting eXpectations, Observing, a Coaching conversation, and Recording/Reflecting. The CBD Coaching Model and its associated RX-OCR faculty development tool support the implementation of coaching in CBME. Coaching in the moment and coaching over time offer important mechanisms by which CBD brings value to trainees. For sustained change to occur and for learners and coaches to experience the model's intended benefits, ongoing professional development efforts are needed. Early post implementation reflections and lessons learned are provided.

ABSTRACT

BACKGROUND: Resident-focused concussion curricula that measure learner behaviours are currently unavailable. We sought to fill this gap by developing and iteratively implementing a Spiral Integrated Concussion Curriculum (SICC). APPROACH: Programme elements of the concussion curriculum include academic half-days (AHDs) and three half-day clinics for first- and second-year family medicine residents. Our SICC utilises social cognitive learning principles, the constructivism paradigm and utilisation-focused evaluation. EVALUATION: A mixed-method evaluation with a pre-/post-test design and interviews was utilised. Surveys and knowledge tests were used to measure knowledge and confidence pre-AHD and 6 months post-AHD. Interviews at 6 months explored programme perception and behaviour change. Of the 141 programme attendees, 114 (80%) participated in the pre-intervention knowledge test and 33 completed the pre- and post-AHD test. Immediate pre-/post-testing demonstrated statistically significant improvement in knowledge (p = 0.042). At 6 months post-AHD, residents in Cycle 1 (n = 5) had a knowledge decrease of 3.33% (p > 0.05). Residents in Cycle 2 (n = 7) had a knowledge increase of 11.6% (p > 0.05). Both cycles of residents had an increase in confidence (Cycle 1: 65.0% [p = 0.025]; Cycle 2: 62.8% [p = 0.0014]). Residents (5 out of 6) reported positive behavioural changes at 6 months. Valued programme elements included concussion diagnosis and management, the self-study guide resource and the organised structure. IMPLICATIONS: The SICC enriched these residents' learning and fostered sustained knowledge improvement and behavioural change at 6 months post-intervention. This approach may provide a workable design for future competency-based curriculum development.

ABSTRACT

INTRODUCTION: Post-stroke delirium (PSD) is a common yet underrecognized complication following stroke, with its effect on stroke rehabilitation being the subject of limited attention. The objective of this narrative review is to provide an overview of core issues in PSD including epidemiology, diagnostic challenges, and management considerations, with an emphasis on the rehabilitation phase. METHODS: Ovid Medline and Google Scholar were searched through February 2023 using keywords related to delirium, rehabilitation, and the post-stroke period. Only studies conducted on adults (≥18 years) and written in the English language were included. RESULTS: PSD affects approximately 25% of stroke patients, and often persists well into the post-acute phase, with a negative impact on rehabilitation outcomes including lengths of stay, function, and cognition. Certain stroke and patient characteristics can help predict risk for PSD. The diagnosis of delirium becomes more challenging when superimposed on stroke deficits (such as attentional impairment or other cognitive, psychiatric, or behavioural disorders), leading to underdiagnosis, overdiagnosis, or misdiagnosis. Particularly in patients with post-stroke language or cognitive disorders, common screening tools are less accurate. The multidisciplinary rehabilitation team should be involved in management of PSD as rehabilitative activities can be beneficial for patients who can participate safely. Addressing barriers to effective delirium care at various levels of the health care system can improve rehabilitation trajectories for these patients. CONCLUSIONS: PSD is a disease entity commonly encountered in the rehabilitation setting, but it is challenging to diagnose and manage. New delirium screening tools and management approaches specific for the post-stroke and rehabilitation settings are needed.

ABSTRACT

PURPOSE: These authors sought to define the new roles and competencies required of administrative staff and faculty in the age of CBME. METHOD: A modified Delphi process was used to define the new CBME roles and competencies needed by faculty and administrative staff. We invited international experts in CBME (volunteers from the ICBME Collaborative email list), as well as faculty members and trainees identified via social media to help us determine the new competencies required of faculty and administrative staff in the CBME era. RESULTS: Thirteen new roles were identified. The faculty-specific roles were: National Leader/Facilitator in CBME; Institutional/University lead for CBME; Assessment Process & Systems Designer; Local CBME Leads; CBME-specific Faculty Developers or Trainers; Competence Committee Chair; Competence Committee Faculty Member; Faculty Academic Coach/Advisor or Support Person; Frontline Assessor; Frontline Coach. The staff-specific roles were: Information Technology Lead; CBME Analytics/Data Support; Competence Committee Administrative Assistant. CONCLUSIONS: The authors present a new set of faculty and staff roles that are relevant to the CBME context. While some of these new roles may be incorporated into existing roles, it may be prudent to examine how best to ensure that all of them are supported within all CBME contexts in some manner.

ABSTRACT

PURPOSE: Patients with poststroke dysphagia may experience inefficient bolus clearance or inadequate airway protection. Following a stroke, impairments in lingual pressure generation capacity are thought to contribute to oropharyngeal dysphagia. The goal of our study was to determine whether similar profiles of swallowing impairment would be seen across a cohort of patients with reduced tongue strength within 3 months after cerebral ischemic stroke. METHOD: The sample comprised six adults with reduced tongue strength (i.e., maximum anterior isometric pressure < 40 kPa). Participants underwent a videofluoroscopy according to a standard protocol. Post hoc blinded ratings were completed using the Analysis of Swallowing Physiology: Events, Kinematics and Timing Method and coded as "typical" versus "atypical" (i.e., within vs. outside the healthy interquartile range) in comparison to published reference values. RESULTS: The videofluoroscopies suggested that having reduced tongue strength did not translate into a common profile. Of the six participants, two showed Penetration-Aspiration Scale (PAS) scores of ≥ 3 on thin liquids, associated with incomplete laryngeal vestibule closure (LVC). Another two participants displayed PAS scores of 2 (transient penetration), but these were not associated with incomplete LVC. Pharyngeal residue, above the healthy 75th percentile, was seen for three participants. Five participants presented with atypical reductions in hyoid XY peak position. CONCLUSIONS: In this cohort of adults within 3 months of cerebral ischemic stroke, reductions in tongue strength presented alongside a variety of changes in swallowing physiology. There was no straightforward relationship linking reduced tongue strength to particular patterns of impairment on videofluoroscopy.

ABSTRACT

Purpose: Upper limb movement disorders are common after stroke and can severely impact activities of daily living. Available clinical measures of these disorders are subjective and may lack the sensitivity needed to track a patient's progress and to compare different therapies. Kinematic analyses can provide clinicians with more objective measures for evaluating the effects of rehabilitation. We present a novel method to assess the quality of upper limb movement: the Kinematic Upper-limb Movement Assessment (KUMA). This assessment uses motion capture to provide three kinematic measures of upper limb movement: active range of motion, speed, and compensatory trunk movement. The researchers sought to evaluate the ability of the KUMA to distinguish motion in the affected versus unaffected limb. Method: We used the KUMA with three participants with stroke to assess three single-joint movements in: wrist flexion and extension, elbow flexion and extension, and shoulder flexion/extension and abduction/adduction. Participants also completed the Modified Ashworth Scale and the Chedoke-McMaster Stroke Assessment, two clinical measures of functional ability. Results: The KUMA distinguished between affected and unaffected upper limb motion. Conclusions: The KUMA provides clinicians with supplementary objective information for motion characterization that is not available through clinical measures alone. The KUMA can complement existing clinical measures such as the MAS and CMSA and can be helpful for monitoring patient progress.


Objectif : les troubles des mouvements de membres supérieurs sont courants après un accident vasculaire cérébral et peuvent nuire fortement aux activités de la vie quotidienne. Les mesures cliniques disponibles pour ces troubles sont subjectives et ne possèdent peut-être pas la sensibilité nécessaire pour suivre le progrès d'un patient et comparer les diverses thérapies. Les analyses de cinématique peuvent fournir aux cliniciens des mesures plus objectives pour évaluer les effets de la réadaptation. Les auteurs présentent une nouvelle méthode pour évaluer la qualité des mouvements des membres supérieurs : l'évaluation cinématique des mouvements des membres supérieurs (KUMA, pour Kinematic Upper-limb Movement Assessment ). Cette évaluation fait appel à la capture des mouvements pour fournir trois mesures cinématiques des mouvements des membres supérieurs : l'amplitude de mouvements actifs, la vitesse et le mouvement compensatoire du tronc. Les chercheurs ont cherché à évaluer la capacité de la KUMA à distinguer le mouvement du membre touché par rapport au membre non touché. Méthodologie : les chercheurs ont utilisé la KUMA auprès de trois participants ayant subi un accident vasculaire cérébral pour évaluer trois mouvements monoarticulaires : flexion et extension du poignet, flexion et extension du coude, et flexion et extension, abduction et adduction de l'épaule. Les participants ont également utilisé l'échelle modifiée d'Ashworth (MAS) et l'évaluation Chedoke-McMaster de l'accident vasculaire cérébral (AVC), deux mesures cliniques de la capacité fonctionnelle. Résultats : la KUMA distinguait le mouvement du membre supérieur atteint de celui qui ne l'était pas. Conclusions : La KUMA fournit aux cliniciens de l'information objective supplémentaires pour caractériser les mouvements d'une manière qui n'est pas disponible par les seules mesures cliniques. La KUMA peut compléter les mesures cliniques en place comme l'échelle modifiée d'Ashworth et l'évaluation Chedoke-McMaster de l'AVC et peut être utile pour surveiller le progrès des patients.

ABSTRACT

The ongoing adoption of competency-based medical education (CBME) across health professions training draws focus to learner-centred educational design and the importance of fostering a growth mindset in learners, teachers, and educational programs. An emerging body of literature addresses the instructional practices and features of learning environments that foster the skills and strategies necessary for trainees to be partners in their own learning and progression to competence and to develop skills for lifelong learning. Aligned with this emerging area is an interest in Dweck's self theory and the concept of the growth mindset. The growth mindset is an implicit belief held by an individual that intelligence and abilities are changeable, rather than fixed and immutable. In this paper, we present an overview of the growth mindset and how it aligns with the goals of CBME. We describe the challenges associated with shifting away from the fixed mindset of most traditional medical education assumptions and practices and discuss potential solutions and strategies at the individual, relational, and systems levels. Finally, we present future directions for research to better understand the growth mindset in the context of CBME.

ABSTRACT

Programmatic assessment as a concept is still novel for many in clinical education, and there may be a disconnect between the academics who publish about programmatic assessment and the front-line clinical educators who must put theory into practice. In this paper, we clearly define programmatic assessment and present high-level guidelines about its implementation in competency-based medical education (CBME) programs. The guidelines are informed by literature and by lessons learned from established programmatic assessment approaches. We articulate five steps to consider when implementing programmatic assessment in CBME contexts: articulate the purpose of the program of assessment, determine what must be assessed, choose tools fit for purpose, consider the stakes of assessments, and define processes for interpreting assessment data. In the process, we seek to offer a helpful guide or template for front-line clinical educators. We dispel some myths about programmatic assessment to help training programs as they look to design-or redesign-programs of assessment. In particular, we highlight the notion that programmatic assessment is not 'one size fits all'; rather, it is a system of assessment that results when shared common principles are considered and applied by individual programs as they plan and design their own bespoke model of programmatic assessment for CBME in their unique context.

ABSTRACT

With the rapid uptake of entrustable professional activties and entrustment decision-making as an approach in undergraduate and graduate education in medicine and other health professions, there is a risk of confusion in the use of new terminologies. The authors seek to clarify the use of many words related to the concept of entrustment, based on existing literature, with the aim to establish logical consistency in their use. The list of proposed definitions includes independence, autonomy, supervision, unsupervised practice, oversight, general and task-specific trustworthiness, trust, entrust(ment), entrustable professional activity, entrustment decision, entrustability, entrustment-supervision scale, retrospective and prospective entrustment-supervision scales, and entrustment-based discussion. The authors conclude that a shared understanding of the language around entrustment is critical to strengthen bridges among stages of training and practice, such as undergraduate medical education, graduate medical education, and continuing professional development. Shared language and understanding provide the foundation for consistency in interpretation and implementation across the educational continuum.

ABSTRACT

The iconic Miller's pyramid, proposed in 1989, characterizes 4 levels of assessment in medical education ("knows," "knows how," "shows how," "does"). The frame work has created a worldwide awareness of the need to have different assessment approaches for different expected outcomes of education and training. At the time, Miller stressed the innovative use of simulation techniques, geared at the third level ("shows how"); however, the "does" level, assessment in the workplace, remained a largely uncharted area. In the 30 years since Miller's conference address and seminal paper, much attention has been devoted to procedures and instrument development for workplace-based assessment. With the rise of competency-based medical education (CBME), the need for approaches to determine the competence of learners in the clinical workplace has intensified. The proposal to use entrustable professional activities as a framework of assessment and the related entrustment decision making for clinical responsibilities at designated levels of supervision of learners (e.g., direct, indirect, and no supervision) has become a recent critical innovation of CBME at the "does" level. Analysis of the entrustment concept reveals that trust in a learner to work without assistance or supervision encompasses more than the observation of "doing" in practice (the "does" level). It implies the readiness of educators to accept the inherent risks involved in health care tasks and the judgment that the learner has enough experience to act appropriately when facing unexpected challenges. Earning this qualification requires qualities beyond observed proficiency, which led the authors to propose adding the level "trusted" to the apex of Miller's pyramid.

ABSTRACT

Background and purpose: Following a stroke, three-dimensional clavicular/scapular/humeral joint rotations may become restricted and contribute to post-stroke shoulder pain. This study examined whether a treatment group provided with current standard treatment plus the proposed "Three-dimensional Shoulder Pain Alignment" mobilization protocol demonstrated improved pain-free shoulder range, functional reach and sleep compared to a control group provided with standard treatment alone.Methods: In this double-blinded parallel-group randomized control trial, treatment and control subjects with moderate/severe post-stroke upper extremity impairment and shoulder pain were treated 3x/week for 4 weeks. Outcome measures included changes in pain-free three-dimensional clavicular/scapular/humeral range (using computerized digitization), pain during sleep and functional reach (using the Pain Intensity-Numerical Rating Scale), and pain location/prognostic indicators (using the Chedoke-McMaster Stroke Assessment-Shoulder Pain Inventory).Results: Compared to controls (n = 10) the treatment group (n = 10) demonstrated significantly improved three-dimensional clavicular/scapular/humeral pain-free range during shoulder flexion and abduction (p < 0.05; Hedges g > 0.80), large effect sizes for decreased pain during sleep and functional reach to the head and back (OR range: 5.44-21.00), and moderate effect size for improved pain/prognostic indicators (OR = 3.86).Conclusions: The Three-Dimensional Shoulder Pain Alignment mobilization protocol significantly improved pain-free range of motion, functional reach and pain during sleep in shoulders with moderate/severe post-stroke upper-extremity impairment.Implications for rehabilitationAlthough three-dimensional clavicular/scapular/humeral rotations are an essential component of normal pain-free shoulder range of motion, current guidelines for treatment of post-stroke shoulder pain only includes uni-dimensional mobilizations for joint alignment and pain management.The Three-Dimensional Shoulder Pain Alignment (3D-SPA) mobilization protocol incorporates multi-dimensional mobilizations in various planes of shoulder movement.The current study results demonstrate proof-of-concept regarding the 3D-SPA mobilization, and this approach should be considered as an alternative to the uni-dimensional mobilizations currently used in clinical treatment guidelines for post-stroke shoulder pain.

ABSTRACT

Vastus medialis (VM) has two partitions, longus (VML), and obliquus (VMO), which have been implicated in knee pathologies. However, muscle architecture of VMO and VML has not been documented volumetrically. The aims of this study were to determine and compare the muscle architecture of VMO and VML in three-dimensional (3D) space, and to elucidate their relative functional capabilities. Twelve embalmed specimens were used in this study. Each specimen was serially dissected, digitized (Microscribe™ MX), and modeled in 3D (Autodesk Maya®). Architectural parameters: fiber bundle length (FBL), proximal (PPA)/distal (DPA) pennation angle, and physiological cross-sectional area (PCSA) were compared using descriptive statistics/t-tests. Sarcomere lengths (SLs) were measured and compared from six biopsy sites of VM. VMO and VML were found to have superficial and deep parts based on fiber bundle attachments to aponeuroses, medial patellar retinaculum, and adductor magnus tendon. The superficial part of VMO was further subdivided into superior and inferior partitions. Architecturally, VMO was found to have significantly shorter mean FBL, greater mean PPA and DPA, and smaller mean PCSA than VML. VML was found to be connected to the fascia lata by thin fascial bands, not present in VMO. SLs of VMO and VML were comparable. VMO and VML are architecturally and functionally distinct, as evidenced by marked differences in their musculoaponeurotic geometry, attachment sites, and architectural parameters. VMO likely contributes greater to medial patellar stabilization, whereas VML, with a larger relative excursion and force-generating capability, to the extension of the knee. Clin.

ABSTRACT

Purpose: Altered three-dimensional (3D) joint kinematics can contribute to shoulder pathology, including post-stroke shoulder pain. Reliable assessment methods enable comparative studies between asymptomatic shoulders of healthy subjects and painful shoulders of post-stroke subjects, and could inform treatment planning for post-stroke shoulder pain. The study purpose was to establish intra-rater test-retest reliability and within-subject repeatability of a palpation/digitization protocol, which assesses 3D clavicular/scapular/humeral rotations, in asymptomatic and painful post-stroke shoulders. Methods: Repeated measurements of 3D clavicular/scapular/humeral joint/segment rotations were obtained using palpation/digitization in 32 asymptomatic and six painful post-stroke shoulders during four reaching postures (rest/flexion/abduction/external rotation). Intra-class correlation coefficients (ICCs), standard error of the measurement and 95% confidence intervals were calculated. Results: All ICC values indicated high to very high test-retest reliability (≥0.70), with lower reliability for scapular anterior/posterior tilt during external rotation in asymptomatic subjects, and scapular medial/lateral rotation, humeral horizontal abduction/adduction and axial rotation during abduction in post-stroke subjects. All standard error of measurement values demonstrated within-subject repeatability error ≤5° for all clavicular/scapular/humeral joint/segment rotations (asymptomatic ≤3.75°; post-stroke ≤5.0°), except for humeral axial rotation (asymptomatic ≤5°; post-stroke ≤15°). Conclusions: This noninvasive, clinically feasible palpation/digitization protocol was reliable and repeatable in asymptomatic shoulders, and in a smaller sample of painful post-stroke shoulders. Implications for Rehabilitation In the clinical setting, a reliable and repeatable noninvasive method for assessment of three-dimensional (3D) clavicular/scapular/humeral joint orientation and range of motion (ROM) is currently required. The established reliability and repeatability of this proposed palpation/digitization protocol will enable comparative 3D ROM studies between asymptomatic and post-stroke shoulders, which will further inform treatment planning. Intra-rater test-retest repeatability, which is measured by the standard error of the measure, indicates the range of error associated with a single test measure. Therefore, clinicians can use the standard error of the measure to determine the "true" differences between pre-treatment and post-treatment test scores.

ABSTRACT

OBJECTIVE: To create a consensus statement on the considerations for treatment of anticoagulated patients with botulinum toxin A (BoNTA) intramuscular injections for limb spasticity. DESIGN: We used the Delphi method. SETTING: A multiquestion electronic survey. PARTICIPANTS: Canadian physicians (N=39) who use BoNTA injections for spasticity management in their practice. INTERVENTIONS: After the survey was sent, there were e-mail discussions to facilitate an understanding of the issues underlying the responses. Consensus for each question was reached when agreement level was ≥75%. MAIN OUTCOME MEASURES: Not applicable. RESULTS: When injecting BoNTA in anticoagulated patients: (1) BoNTA injections should not be withheld regardless of muscles injected; (2) a 25G or smaller size needle should be used when injecting into the deep leg compartment muscles; (3) international normalized ratio (INR) level should be ≤3.5 when injecting the deep leg compartment muscles; (4) if there are clinical concerns such as history of a fluctuating INR, recent bleeding, excessive or new bruising, then an INR value on the day of injection with point-of-care testing or within the preceding 2-3 days should be taken into consideration when injecting deep compartment muscles; (5) the concern regarding bleeding when using direct oral anticoagulants (DOACs) should be the same as with warfarin (when INR is in the therapeutic range); (6) the dose and scheduling of DOACs should not be altered for the purpose of minimizing the risk of bleeding prior to BoNTA injections. CONCLUSIONS: These consensus statements provide a framework for physicians to consider when injecting BoNTA for spasticity in anticoagulated patients. These consensus statements are not strict guidelines or decision-making steps, but rather an effort to generate common understanding in the absence of evidence in the literature.

ABSTRACT

BACKGROUND: Resident perspectives on feedback are key determinants of its acceptance and effectiveness, and provider credibility is a critical element in perspective formation. It is unclear what factors influence a resident's judgment of feedback credibility. OBJECTIVE: We examined how residents perceive the credibility of feedback providers during a formative objective structured clinical examination (OSCE) in 2 ways: (1) ratings of faculty examiners compared with standardized patient (SP) examiners, and (2) ratings of faculty examiners based on alignment of expertise and station content. METHODS: During a formative OSCE, internal medicine residents were randomized to receive immediate feedback from either faculty examiners or SP examiners on communication stations, and at least 1 specialty congruent and either 1 specialty incongruent or general internist faculty examiner for clinical stations. Residents rated perceived credibility of feedback providers on a 7-point scale. Results were analyzed with proportional odds models for ordinal credibility ratings. RESULTS: A total of 192 of 203 residents (95%), 72 faculty, and 10 SPs participated. For communication stations, odds of high credibility ratings were significantly lower for SP than for faculty examiners (odds ratio [OR] = 0.28, P < .001). For clinical stations, credibility odds were lower for specialty incongruent faculty (OR = 0.19, P < .001) and female faculty (OR = 0.45, P < .001). CONCLUSIONS: Faculty examiners were perceived as being more credible than SP examiners, despite standardizing feedback delivery. Specialty incongruency with station content and female sex were associated with lower credibility ratings for faculty examiners.
