RESUMO

BACKGROUND: Outcomes of national policy change impact all levels of the organizational hierarchy. The medical education literature is sparse on how reflections from program directors (PDs) on past large-scale policy changes can inform future policy initiatives. To fill this gap, we conducted a national survey on PDs' perceptions of, and reflections on, decision-making in medical education, accreditation procedures, and the CanMEDS framework implementation. METHODS: The survey was distributed to former Canadian specialty medicine PDs (N = 684). Descriptive analysis was performed on quantitative data, thematic analysis was performed on qualitative comments, and comparisons between the quantitative and qualitative findings were performed to identify areas of convergence and/or divergence. RESULTS: A total of 265 (38.7%) former PDs participated. Quantitative analysis revealed that 52.8% of respondents did not feel involved in decision-making regarding policy changes, 45.1% of respondents did not feel prepared to assess the CanMEDS Roles, and PDs were divided on the reasonableness of accreditation documentation. Qualitative analysis produced four themes: communication, resources, expectations of outcomes, and buy-in. Nine sub-themes were also identified. A high level of convergence was identified across the content, with only four areas of divergence identified. CONCLUSIONS: Our findings have the potential to inform future policy and/or accreditation changes. Without the lens of those charged with overseeing the implementation, policy evaluation and quality improvement will remain uninformed. PDs, therefore, bring unique insights into our understanding of national policy changes, and without the voices of these frontline implementers, the true success of policy change implementation will be hindered.


CONTEXTE: Les effets des changements apportés aux politiques nationales se font sentir à tous les niveaux de la hiérarchie organisationnelle. La littérature traite peu du fait que l'opinion des directeurs de programme (DP) concernant les réformes d'envergure intervenues dans les politiques sur l'éducation médicale par le passé peut servir à éclairer les révisions de politiques futures. Afin de combler cette lacune, nous avons mené une enquête nationale pour sonder les DP sur leurs perceptions et réflexions quant à la prise de décision dans l'éducation médicale, aux procédures d'agrément et à la mise en œuvre du cadre CanMEDS. MÉTHODES: Le sondage a été distribué aux anciens DP en médecine spécialisée du Canada (N = 684). Les données quantitatives ont fait l'objet d'une analyse descriptive, les commentaires qualitatifs d'une analyse thématique, et une comparaison entre les résultats quantitatifs et qualitatifs a été effectuée pour repérer les domaines de convergence et de divergence. RÉSULTATS: Un total de 265 (38.7%) anciens DP ont participé au sondage. L'analyse quantitative a révélé que 52.8% des répondants ne se sentaient pas inclus dans la prise de décision en matière de changements de politiques, que 45.1% des répondants ne se sentaient pas en mesure d'évaluer les rôles CanMEDS, et qu'ils étaient partagés sur la question du caractère raisonnable des documents d'agrément. L'analyse qualitative a permis de dégager quatre thèmes: la communication, les ressources, les attentes en matière de résultats et l'adhésion. Neuf sous-thèmes ont également été définis. Nous avons constaté un niveau élevé de convergence sur l'ensemble du contenu, des divergences n'apparaissant que dans quatre domaines. CONCLUSIONS: Nos conclusions peuvent servir à orienter les changements futurs en matière de politiques et d'agrément. Sans le regard de ceux qui sont chargés de superviser leur mise en œuvre, l'évaluation des politiques et l'amélioration de la qualité demeureront mal fondées. La perspective unique des DP est essentielle à notre compréhension des révisions des politiques, et sans la contribution de ces responsables de première ligne de leur application, les réformes ne pourront être mises en œuvre de façon optimale.

RESUMO

RATIONALE AND OBJECTIVES: The relative competitiveness of radiology and the number of first-choice applicants to diagnostic radiology have steadily declined over the past decade. The purpose of this study was to identify factors contributing to the declining interest in diagnostic radiology as a career and to explore factors affecting specialty choice. MATERIALS AND METHODS: A retrospective survey was distributed to resident physicians at a single academic center between July and August 2017. Participants identified factors affecting career choice and evaluated level of agreement with statements regarding radiology using 5-point Likert scales. Higher scores indicated stronger agreement. RESULTS: One hundred and fifty-two resident physicians from Canada participated (21.5% response rate): 20 radiology and 132 nonradiology. Of the total, 27% were registered in postgraduate year (PGY) 1, 23% in PGY 2, 15% in PGY 3, 19% in PGY 4, and 16% in PGY 5, or above. Sixty-one percent of the respondents self-reported as female, 34% as male, and 5% as other/unknown. Of those in radiology, 40% self-reported as female, 55% as male, and 5% as other/unknown, compared to 64% female, 31% male, and 5% other/unknown in other specialties. Regardless of specialty, positive clinical/mentoring experiences strongly affected career choice. Radiology residents were attracted to diverse pathology (M = 4.5) and positive staff/resident interactions (M = 4.4). Nonradiology residents were deterred by lack of patient contact (M = 3.9) and dark work environment (M = 3.6). Resident physicians who had applied to radiology were more likely to report positive mentorship during medical school, disagree that technology will replace radiologists, and desire a higher income specialty (Wald = 56.6, p < 0.001). More recent graduates showed a higher level of concern regarding the potential negative impact of technology and outsourcing on the profession (F (3, 189) = 2.6, p = 0.05). Several trainees (21%) considered radiology, but lacked mentorship (52%) and identified job market concerns (29%). CONCLUSION: More recent graduates are relatively more concerned about technology replacing radiologists, and radiology applicants have less concern about artificial intelligence replacing radiologists. As positive interactions with radiologists and mentorship are key influencers, our results advocate for early training exposure and reinforcement regarding the positive outlook of the profession.

RESUMO

OBJECTIVE. Underrepresentation of women in the top hierarchy of academic medicine exists despite women comprising more than half of the medical school graduates and residency positions. The purpose of this study is to analyze and quantify the relationship of gender, research productivity, and career advancement in Canadian academic radiology departments. MATERIALS AND METHODS. Seventeen academic radiology departments with affiliated residency programs in Canada were searched for publicly available data on faculty to generate a database for gender and academic profiles of the radiologists. Bibliometric data were collected using Scopus archives. The associations of gender, academic ranks, and leadership positions were assessed, and a p value of ≤ 0.05 was defined as significant. Significant variables were analyzed using a multivariate linear regression model. RESULTS. Of 1266 faculty members, gender information and academic rank were available for 932 faculty members: 597 (64.05%) were men and 335 (35.95%) were women (χ2 = 21.82; p < 0.0001). Of a total of 563 assistant professors, 331 (58.79%) were men and 232 (41.21%) were women; of 258 associate professors, 177 (68.60%) were men and 81 (31.40%) were women; and of 111 professors, 89 (80.18%) were men and 22 (19.82%) were women. The gender gap widens at higher academic ranks, displaying a threefold drop in the ratio of women holding the rank of full professor (6.57%) compared with 14.91% male professors; 29.55% of women radiologists have first-in-command leadership positions compared with 70.45% of men. A comparable or higher h-index is noted for women Canadian radiologists after adjusting for number of citations, number of publications, and years of active research. CONCLUSION. Canadian academic radiology departments have fewer women radiologists in senior faculty and leadership positions. Our study results show that Canadian female radiologists at the professor level have more publications than their male counterparts.

RESUMO

RATIONALE AND OBJECTIVES: Traditional assessments in radiology residency focus on the Medical Expert CanMEDS role and typically rely upon a single or limited static images. We designed an Emergency Radiology Simulator that aimed to assess the breadth of competencies required across Medical and NonMedical Expert domains. MATERIAL AND METHODS: An online simulator with typical emergency cases was administered in October 2015 to Post Graduate Year (PGY) 2-5 residents in Radiology. Residents provided preliminary reports, which were graded for style and content. The simulation also included prioritization, protocoling, counseling, and handover exercises geared to assess NonMedical Expert roles. RESULTS: Fourty eight residents participated in the simulation. Level of resident was 11 PGY-2, 17 PGY-3, 13 PGY-4, and 7 PGY-5. There was a significant difference in resident performance between PGY-2 residents and those more senior in terms of the Medical Expert role (findings, diagnosis, recommendations, and clinical relevance of reports). Differences in performance between PGY levels were not seen in the NonMedical Expert roles (prioritization, protocoling, counseling, and handover). CONCLUSION: Simulation provides an opportunity to assess radiology resident performance across multiple domains. PGY-2 residents performed worse on the Medical Expert domains, although performance did not significantly vary between the other years. This may suggest that competence in Emergency Radiology is achieved early in residency, possibly related to the importance placed on developing skills related to on-call performance during the PGY-2 year. The simulator should be extended to other areas of Radiology, in order to assess the ability to discriminate performance in other subspecialties.

RESUMO

PURPOSE: The study aimed to examine the postresidency plans of Canadian radiology residents and factors influencing their fellowship choices and practice preferences, including interest in teaching and research. METHODS: Institutional ethics approval was obtained at McMaster University. Electronic surveys were sent to second to fifth-year residents at all 16 radiology residency programs across Canada. Each survey assessed factors influencing fellowship choices and practice preferences. RESULTS: A total of 103 (31%) Canadian radiology residents responded to the online survey. Over 89% from English-speaking programs intended to pursue fellowship training compared to 55% of residents from French-speaking programs. The most important factors influencing residents' decision to pursue fellowship training were enhanced employability (46%) and personal interest (47%). Top fellowship choices were musculoskeletal imaging (19%), body imaging (17%), vascular or interventional (14%), neuroradiology (8%), and women's imaging (7%). Respondents received the majority of their fellowship information from peers (68%), staff radiologists (61%), and university websites (58%). Approximately 59% planned on practicing at academic institutions and stated that lifestyle (43%), job prospects (29%), and teaching opportunities (27%) were the most important factors influencing their decisions. A total of 89% were interested in teaching but only 46% were interested in incorporating research into their future practice. CONCLUSIONS: The majority of radiology residents plan on pursuing fellowship training and often receive their fellowship information from informal sources such as peers and staff radiologists. Fellowship directors can incorporate recruitment strategies such as mentorship programs and improving program websites. There is a need to increase resident participation in research to advance the future of radiology.

RESUMO

PURPOSE: The objective of the study was to characterize the radiographic appearance of graft resorption and new bone incorporation into a postresection defect of the calcium-sulfate calcium-phosphate synthetic bone graft composite following resection of benign bone tumours. METHODS: Twenty-five patients who underwent treatment with the CaSO4/CaPO4 synthetic graft following bone tumour resection were retrospectively identified from our oncology database. Postoperative radiographs were assessed for: 1) combined partial graft resorption and ingrowth at the graft site; 2) complete graft resorption with complete incorporation of new bone into the defect. After chronologically grouping radiographs, the volume of graft material used to fill bony defects, radiographic evidence of complications, and patterns of resorption were recorded. RESULTS: Partial resorption of graft material/partial ingrowth of new bone was seen in 21 patients at 2.5 months postoperatively. Complete resorption of graft with complete new bone incorporation at the graft site was seen in 94% of cases (15 of 16) by 10 months after surgery. Mean time to complete incorporation of new bone was 6.7 months. Time to resorption of the graft with new bone ingrowth was found to be related to the volume of graft used with smaller volumes showing earlier resorption. For all cases demonstrating resorption (21 of 21), the pattern observed was peripheral to central. Five patients developed complications, including tumour recurrence, cyst formation, and graft site infection. CONCLUSION: Our study suggests a characteristic time and volume related radiographic pattern of resorption and new bone ingrowth with the CaSO4/CaPO4 synthetic graft. Findings that deviate from this pattern may represent complication and warrant additional follow-up.

RESUMO

BACKGROUND: Permanent joint damage is a major consequence of rheumatoid arthritis (RA), the most common and destructive form of inflammatory arthritis. In aggressive disease, joint damage can occur within 6 months from symptom onset. Early, intensive treatment with conventional and biologic disease-modifying anti-rheumatic drugs (DMARDs) can delay the onset and progression of joint damage. The primary objective of the study is to investigate the value of magnetic resonance imaging (MRI) or radiography (X-ray) over standard of care as tools to guide DMARD treatment decision-making by rheumatologists for the care of RA. METHODS: A double-blind, randomized controlled trial has been designed. Rheumatoid and undifferentiated inflammatory arthritis patients will undergo an MRI and X-ray assessment every 6 months. Baseline adaptive randomization will be used to allocate participants to MRI, X-ray, or sham-intervention groups on a background of standard of care. Prognostic markers, treating physician, and baseline DMARD therapy will be used as intervention allocation parameters. The outcome measures in rheumatology RA MRI score and the van der Heijde-modified Sharp score will be used to evaluate the MRI and X-ray images, respectively. Radiologists will score anonymized images for all patients regardless of intervention allocation. Disease progression will be determined based on the study-specific, inter-rater smallest detectable difference. Allocation-dependent, intervention-concealed reports of positive or negative disease progression will be reported to the treating rheumatologist. Negative reports will be delivered for the sham-intervention group. Study-based radiology clinical reports will be provided to the treating rheumatologists for extra-study X-ray requisitions to limit patient radiation exposure as part of diagnostic imaging standard of care. DMARD treatment dose escalation and therapy changes will be measured to evaluate the primary objective. A sample size of 186 (62 per group) patients will be required to determine a 36% difference in pharmacological treatment escalation between the three groups with intermediate dispersion of data with 90% power at a 5% level of significance. DISCUSSION: This study will determine if monitoring RA and undifferentiated inflammatory arthritis patients using MRI and X-ray every 6 months over 2 years provides incremental evidence over standard of care to influence pharmacotherapeutic decision-making and ultimately hinder disease progression. TRIAL REGISTRATION: This trial has been registered at ClinicalTrials.gov: NCT00808496 (registered on 12 December 2008).

RESUMO

Benign primary bone tumors are commonly treated with intralesional curettage with or without the use of surgical adjuvants. The reconstructive approach to the resulting contained bone defects is controversial, and clinical practice is varied. Synthetic bone substitutes may provide early mechanical support while minimizing the risks of disease transmission, nonunion, infection, and donor-site morbidity. Limited data exists regarding the use of calcium sulfate-calcium phosphate composite bone substitute for this purpose. The authors retrospectively reviewed the clinical outcomes of 24 patients with benign primary bone tumors who underwent intralesional curettage followed by reconstruction with a calcium sulfate-calcium phosphate composite bone substitute. Mean follow-up was 23 months. The most common diagnosis was giant cell tumor of bone. Six patients had upper-extremity tumors and 18 had lower-extremity tumors. Mean preoperative radiographic tumor volume was 41.0 cm(3). Mean volume of PRO-DENSE (Wright Medical Technology, Arlington, Tennessee) used in each patient was 15.6 cm(3). Mean time to full weight bearing for all patients was 7.3 weeks. Two patients sustained local tumor recurrences. No postoperative fractures occurred, and no complications occurred related to the use of the calcium sulfate-calcium phosphate composite. One case of deep infection occurred secondary to wound breakdown. The use of a calcium sulfate-calcium phosphate composite was associated with rapid biological integration and an early return to activities of daily living, with no composite-related complications. This technique is a viable option in the reconstruction of cavitary bone defects following intralesional curettage of primary benign bone tumors.

RESUMO

The osseous pelvis is a well-recognized site of origin of numerous primary and secondary musculoskeletal tumors. The radiologic evaluation of a pelvic lesion often begins with the plain film and proceeds to computed tomography (CT), or magnetic resonance imaging (MRI) and possibly biopsy. Each of these modalities, with inherent advantages and disadvantages, has a role in the workup of pelvic osseous masses. Clinical history and imaging characteristics can significantly narrow the broad differential diagnosis for osseous pelvic lesions. The purpose of this review is to familiarize the radiologist with the presentation and appearance of some of the common benign neoplasms of the osseous pelvis and share our experience and approach in diagnosing these lesions.

RESUMO

Malignant lesions of the pelvis are not uncommon and need to be differentiated from benign lesions and tumor mimics. Appearances are sometimes nonspecific leading to consideration of a broad differential diagnosis. Clinical history, anatomic location, and imaging characterization can help narrow the differential diagnosis. The focus of this paper is to demonstrate the imaging features and the role of plain films, computed tomography, and magnetic resonance imaging for detecting and characterizing malignant osseous pelvic lesions and their common mimics.

RESUMO

This study assessed adherence to the law of contagion by 118 undergraduate students (39 males). Participants were students who played a slot machine game after viewing a prior player who seemed to be winning ("lucky" condition) or losing ("unlucky" condition). Adherence to the law of contagion was assessed by the selection of the coin holder used by a "lucky" prior player and the avoidance of the coin holder used by an "unlucky" prior player. Contagion varied directly with scores on the Problem Gambling Severity Index and scores on the Luck/Perseverance subscale of the Gamblers' Belief Questionnaire (Steenbergh et al. in Psychol Addict Behav 16(2):143-149, 2002). Gamblers high in problem severity chose the "lucky" coin holder and avoided the "unlucky" coin holder significantly more than gamblers low in problem severity. Problem gamblers, therefore, exhibit evidence of magical thinking related to the transfer of a "lucky" essence. The same was the case for individuals with a strong level of belief that sheer continuation in gambling (luck perseverance) results in success and for individuals who believe that luck is a personal rather than a situational characteristic. All three variables (problem gambling severity, luck perseverance and personal luck) had direct effects on behavior reflecting irrational magical thinking. A belief that knowledge or skill has a role in successful gaming was unrelated to magical thinking. These findings suggest potential foci for cognitive interventions with problem gamblers and those with non-skill based evidence of irrational thinking.

RESUMO

OBJECTIVE: To describe the normal chronological radiographic appearances of the calcium sulphate-calcium phosphate (CaSO(4)/CaPO(4)) synthetic graft material following bone tumour resection during the processes of graft resorption and new bone incorporation into the post-resection defect. MATERIALS AND METHODS: Retrospective review of our oncology database identified patients who had undergone serial radiographic assessment after treatment with the CaSO(4)/CaPO(4) synthetic graft following bone tumour resection. Post-operative radiographs were assessed for (1) partial resorption of graft material with partial ingrowth of new bone at the graft site and (2) complete resorption of graft material with complete incorporation of new bone into the graft site. The pattern of resorption of graft material was also documented. Any radiographic evidence of complication was recorded. Radiographs were also divided into groups according to their interval from surgery to establish a pattern of time-related changes. RESULTS: A total of 11 patients were identified from our database. Partial resorption of graft material/partial ingrowth of new bone was seen in nine patients, initially observed at a mean of 1.4 months from surgery. Resorption commenced peripherally with gradual inward progression in 100% (9 of 9) of cases. Complete resorption of graft/complete new bone incorporation at the graft site was seen in 89% (8 of 9) of cases followed up for more than 5 months after surgery. The other patient developed recurrence of tumour at 14 months, before complete incorporation was demonstrated. The mean time to complete incorporation of new bone was 5 months. Two patients have, to date, been followed up at 2 and 3 months respectively with a pattern of peripheral graft resorption observed so far in both cases. Ten of 13 (77%) radiographs performed 1-3 months after surgery demonstrated peripheral resorption of graft material with partial osseous ingrowth into the defect. Seven of eight (88%) radiographs performed 6-12 months after surgery demonstrated complete new bone incorporation at the graft site with graft material completely resorbed. Ten of 11 (91%) radiographs performed 1 year after surgery demonstrated complete new bone incorporation, the other examination demonstrating recurrence. CONCLUSION: Our preliminary observations suggest a characteristic, time-related radiographic pattern during the processes of CaSO(4)/CaPO(4) bone graft resorption and complete new bone incorporation. This pattern can be directly related to processes that occur at the molecular level. Radiographic findings that are not in keeping with this may merit closer follow-up.

RESUMO

The peripheral nerves of the upper limb are affected by a number of entrapment and compression neuropathies. These discrete syndromes involve the brachial plexus as well as the musculocutaneous, axillary, suprascapular, ulnar, radial, and median nerves. Clinical examination and electrophysiologic studies are the traditional mainstay of diagnostic work-up; however, ultrasonography and magnetic resonance imaging provide spatial information regarding the affected nerve and its surroundings, often assisting in narrowing the differential diagnosis and guiding treatment. Imaging is particularly valuable in complex cases with discrepant nerve function test results. Familiarity with the clinical features of various peripheral neuropathies of the upper extremity, the relevant anatomy, and the most common sites and causes of nerve entrapment assists in diagnosis and treatment.

RESUMO

Lymphoreticular neoplasms primarily arise in extraskeletal locations with skeletal involvement usually secondary to hematogenous spread or by direct invasion from surrounding involved lymph nodes or soft tissues. Primary lymphoma of bone is relatively rare in comparison. Lymphoma encompasses Hodgkin's and non-Hodgkin's disease, Burkitt's lymphoma, and mycosis fungoides. Skeletal disease may present with symptoms localized to the site of bone involvement, as an incidental finding on imaging for other reasons, or as part of the staging of the disease. It is important that the radiologist is cognizant of the many presentations of skeletal lymphoma. We present a review of the radiological imaging of skeletal lymphoma with conventional radiographs, computed tomography, scintigraphic studies, and magnetic resonance imaging.

RESUMO

This research examined the effects of a casino's auditory character on estimates of elapsed time while gambling. More specifically, this study varied whether the sound heard while gambling was ambient casino sound alone or ambient casino sound accompanied by music. The tempo and volume of both the music and ambient sound were varied to manipulate temporal engagement and introspection. One hundred and sixty (males = 91) individuals played slot machines in groups of 5-8, after which they provided estimates of elapsed time. The findings showed that the typical ambient casino auditive environment, which characterizes the majority of gaming venues, promotes understated estimates of elapsed duration of play. In contrast, when music is introduced into the ambient casino environment, it appears to provide a cue of interval from which players can more accurately reconstruct elapsed duration of play. This is particularly the case when the tempo of the music is slow and the volume is high. Moreover, the confidence with which time estimates are held (as reflected by latency of response) is higher in an auditive environment with music than in an environment that is comprised of ambient casino sounds alone. Implications for casino management are discussed.

RESUMO

Ultrasound is a valuable imaging modality for evaluation of patients presenting with wrist pain. An important advantage is the ability to correlate the site of pain or discomfort with the underlying sonographic appearance. The capacity to dynamically assess the wrist and use the contralateral asymptomatic wrist for comparison purposes are strengths of ultrasound as a diagnostic tool. This pictorial review deals with the sonographic assessment of the commonly encountered wrist pathologies.

RESUMO

BACKGROUND: Revalidation of the medical profession is under review and a system has been proposed to ensure doctors meet standards of practice and professionalism. The current appraisal system allows clinicians to chart their progress and identify developmental needs in order to improve performance. Appraisal is now an annual compulsory requirement for all doctors. AIM AND OBJECTIVES: The aim of the study was to investigate the experiences of general practitioners (GPs) of the current appraisal process. The specific objectives were to consider the impact the appraisal process had exerted on their learning, practice and individual continuing professional development (CPD). METHODS: We employed a cross-sectional design using a postal questionnaire sent to all doctors who work as GPs (n = 385) in West Kent. MAIN RESULTS: Questionnaires were returned from 71.7% of doctors (n = 276). The key findings obtained were that 47.5% (n = 131) of doctors stated that taking part in the appraisal process had enhanced their learning, 40.2% (n = 111) felt that the appraisal process had improved their practice and 55.8% (n = 154) stated that the appraisal process had encouraged their CPD. Qualitative findings derived from thematic analysis of open questions revealed that participants viewed the role of the appraiser as respected peer to be vital and there was a need for independence in the appraiser's appointment. The time-consuming nature of the appraisal process was emphasised, with little protected time for preparation of documentation and engagement in CPD. Concerns were expressed about links between appraisal and revalidation. CONCLUSIONS: Many doctors considered that the appraisal process had enhanced their learning, improved their practice and encouraged their CPD. A vital, independent role for the appraiser was emphasised as was a need to review the time-consuming nature of the current appraisal process, together with identifying protected time to complete this and CPD engagement. As the role of appraisal within the revalidation process changes it is recognised that ensuring the quality, consistency and nature of appraisal will be essential to maintain the confidence of patients and doctors.
