Post competency training in standardized training of resident physicians and integrated postgraduates

We focus on the importance and necessity of post-competency-based training in medical education alongside its current challenges and opportunities. Integrating post competency training into standardized educational frameworks is increasingly recognized as a critical component of preparing residents and postgraduates for real-world clinical practice. Post competency training represents a commitment to excellence in medical education, striving to produce competent, skilled practitioners to meet the challenges of modern healthcare.

Educational and personal impacts of the COVID-19 pandemic on emergency medicine resident physicians: a qualitative study

BackgroundThe COVID-19 pandemic had a significant impact on both the clinical practice and the psychological states of frontline physicians in the emergency department. Trainees, at the beginning of their careers and thus still developing their practice styles and identities as physicians, were uniquely affected.ObjectiveIn this qualitative study, we sought to explore how the pandemic environment shaped the experiences of emergency medicine resident physicians.MethodsThis was a qualitative study. We conducted in-depth interviews with emergency medicine faculty, resident physicians, and staff at a single emergency department based at an urban academic institution in the northeastern United States. Interviews were audio recorded and transcribed, and transcripts were then analyzed in an iterative process by our coding team for recurring themes related to the resident experience.ResultsWe reached data saturation with 27 individuals. Of those who were interviewed, 10 were resident physicians [6 senior residents (PGY-3 or PGY-4) and 4 junior residents (PGY-1 or PGY-2)]. Three major recurring themes regarding resident physician experience emerged during our analysis of the interviews: (1) novel educational experiences dampened by negative structural forces from the pandemic, (2) fracturing of social interactions and mitigation through ad-hoc support systems and community of practice, and (3) development of negative emotions and psychological trauma including fear, resentment, and moral injury causing lasting harm.ConclusionsOur results suggest that emergency medicine resident physicians training during the COVID-19 pandemic faced unique experiences concerning their education, social support systems, and emotional states. While the educational and social experiences were described as having both negative and positive impacts, the emotional experiences were largely negative. Residency program leadership may use these insights to improve resident preparation, wellness, and resilience in the face of future adverse events.

Surgical Residents' Perception of Feedback on Their Education: Protocol for a Scoping Review.

Feedback is an essential tool for learning and improving performance in any sphere of education, including training of resident physicians. The learner's perception of the feedback they receive is extremely relevant to their learning progress, which must aim at providing qualified care for patients. Studies pertinent to the matter differ substantially with respect to methodology, population, context, and objective, which makes it even more difficult to achieve a clear understanding of the topic. A scoping review on this theme will unequivocally enhance and organize what is already known. The aim of this study is to identify and map out data from studies that report surgical residents' perception of the feedback received during their education. The review will consider studies on the feedback perception of resident physicians of any surgical specialty and age group, attending any year of residency, regardless of the type of feedback given and the way the perceptions were measured. Primary studies published in English, Spanish, and Portuguese since 2017 will be considered. The search will be carried out in 6 databases and reference lists will also be searched for additional studies. Duplicates will be removed, and 2 independent reviewers will screen the selected studies' titles, abstracts, and full texts. Data extraction will be performed through a tool developed by the researchers. Descriptive statistics and qualitative analysis (content analysis) will be used to analyze the data. A summary of the results will be presented in the form of diagrams, narratives, and tables. The findings of this scoping review were submitted to an indexed journal in July 2024, currently awaiting reviewer approval. The search was executed on March 15, 2024, and resulted in 588 articles. After the exclusion of the duplicate articles and those that did not meet the eligibility criteria as well as the inclusion of articles through a manual search, 13 articles were included in the review. Conducting a scoping review is the best way to map what is known about a subject. By focusing on the feedback perception more than the feedback itself, the results of this study will surely contribute to gaining a deeper understanding of how to proceed to enhance internal feedback and surgical residents' learning progress.

Effectiveness of PBL Pedagogy Combined with Flipped Classroom in the Standardized Training of Resident Physicians

Objective: To analyze the application effect of the problem-based learning (PBL) teaching method combined with flipped classrooms in the standardized training of gastroenterology residents. Methods: Sixty-five resident trainees who were admitted to the Department of Gastroenterology of the hospital from January to December 2023 were selected and divided into the control group (n = 33) and the observation group (n = 32) by random number division method. The control group implemented the traditional clinical teaching method, and the observation group implemented the PBL combined flipped classroom teaching method. The study compared the two groups’ discharge learning performance, trainees’ subjective feeling score, and teaching satisfaction score index. Results: The difference in basic knowledge scores between the two groups of trainees under different teaching modes was not statistically significant (P > 0.05). However, the observation group was significantly higher than the control group in terms of the differences in case analysis, clinical operation skills, and total scores, and the differences were statistically significant (P < 0.05). The trainees of the observation group were more satisfied with the teaching and learning process in terms of learning efficiency, clinical thinking, communication, faculty-student collegiality, teamwork, self-study ability, classroom atmosphere, independent learning, clinical thinking and other subjective feelings of the scores are higher than the control group, the difference is statistically significant (P < 0.05). The observation group teaching total satisfaction rate is 96.87%, significantly higher than the control group’s 75.75% (P < 0.05). Conclusion: The application of the PBL teaching method combined with flipped classroom in the standardized training of residents is effective, which can not only significantly improve the basic theory and practical operation performance of the trainees, but also help to improve their case analysis ability, clinical thinking ability, and doctor-patient communication ability, so it is worthwhile to popularize its application in the clinical scope.

The Application of Distance Education Technology in Standardized Training of Resident Physicians in Primary Orientation Training

This paper explores the application of distance education technology in standardized training of resident physicians in primary orientation training. With the rapid development and popularization of distance education technology, the special needs faced by primary medical institutions in resident physician training are becoming increasingly prominent. By analyzing the current application state, it is found that distance education technology can effectively promote the sharing of high-quality educational resources, improve the flexibility and coverage of training, moreover, it also faces challenges such as technological equipment limitations and insufficient teacher-student interaction. To optimize the application effect, this paper proposes strategies such as strengthening technical support, optimizing teaching content and form, and establishing a sound training effect evaluation system. This study not only helps to improve the training quality of primary resident physicians, but also has important significance for improving the level of primary medical services. Looking to the future, distance education technology will play a greater role in the training of primary resident physicians, which is of great significance for improving the level of primary medical services.

Estimating the size and scope of the academic emergency physician workforce.

Academic emergency medicine (EM) is foundational to the EM specialty through the development of new knowledge and clinical training of resident physicians. Despite recent increased attention to the future of the EM workforce, no evaluations have specifically characterized the U.S. academic EM workforce. We sought to estimate the national proportion of emergency physicians (EPs) identified as academic and the proportion of emergency department (ED) visits that take place at academic sites. We performed a cross-sectional analysis of EPs and EDs using data from the American Hospital Association, the Centers for Medicare & Medicaid Services, and Doximity's Residency Navigator. EPs were identified as "academic" if they were affiliated with at least one facility determined to be academic, defined as EDs officially designated by the Accreditation Council for Graduate Medical Education (ACGME) as clinical training sites at accredited EM residency programs. Our primary outcomes were to estimate the national proportion of EPs identified as academic and the proportion of ED visits performed at academic sites. Our analytic sample included 26,937 EPs practicing clinically across 4920 EDs and providing care during 130,471,386 ED visits. Among EPs, 11,720 (43.5%) were identified as academic, and among EDs, 635 (12.9%) were identified as academic sites, including 585 adult/general sites, 45 pediatric-specific sites, and 10 sites affiliated with the Department of Veterans Affairs. In 2021, academic EDs provided care for 42,794,106 ED visits or 32.8% of all ED visits nationally. Approximately four in 10 EPs practice in at least one clinical training site affiliated with an ACGME-accredited EM residency program, and approximately one in three ED visits nationally occur in these academic EDs. We encourage further work using alternative definitions of an academic EPs and EDs, along with longitudinal research to identify trends in the workforce's composition.

What are the barriers to health professionals' training on gender-affirming care from patients' and clinicians’ perspectives?

ObjectiveThe aim of the study is to identify the barriers to gender-affirming health care education for providers from the perspectives of patients and providers. MethodsA qualitative study based on grounded theory was conducted. Participants included transgender and gender diverse (TGD) patients seeking care, as well as resident physicians and attending physicians involved in care of patients seeking gender-affirming care. Semi-structured interviews were conducted over Zoom application and telephone calls. The study was conducted in Boston, Massachusetts, USA from November 2022 until February 2023. ResultsNine attending physicians, eight resident physicians, and fifteen patients were interviewed. Attending physicians noted barriers to include lack of formal training in medical school and residency, lack of adequate opportunities for faculty development to appropriately train resident physicians, lack of opportunities for trainees to provide dedicated clinical care, lack of community engagement initiatives, and need for additional training centered on cultural sensitivity and inclusivity. Resident physicians noted a lack of robust and longitudinal didactic curriculum, deficiency in dedicated clinical time, and inadequacy in interprofessional training as major barriers to their training. They noted that they generally felt unprepared to care for TGD patients. Patients' barriers included difficulty building trust in medical providers’ knowledge and skills, being addressed with incorrect names and pronouns, lacking a sense of belonging as a patient, as well as difficulty in arranging care due to lack of a centralized care system. ConclusionBarriers to gender-affirming education include lack of adequate and formal training, lack of professional development opportunities, inadequacy in a multidisciplinary approach to treatment and education, and inadequacy in cultural and sensitivity training. Findings of this qualitative study based on interviews may help facilitate addressing such barriers through creation of routine lecture-based didactic opportunities for providers, investment in faculty development, creation of gender-affirming clinics, providing opportunities for trainees to provide longitudinal care to TGD patients, creation of interdisciplinary training modules, community engagement, and implementation of a multidisciplinary care model, which may help improve gender-affirming care in the long-run.

Reporting radiographers in Norway – A qualitative study on implementation, organisation, and outcomes

IntroductionWorldwide, there is an increasing use of imaging services and a shortage of radiologists. One potential solution to this challenge involves introducing task shifting, where radiographers actively contribute to reporting diagnostic images alongside radiologists. This study explored the purpose and value of reporting radiographers in Norway's imaging departments. MethodsThis study used a qualitative design with a descriptive approach. Semi-structured interviews were conducted with eleven participants, comprising managers, radiologists, and reporting radiographers, from four hospital trusts in south Norway. The collected data were analysed using inductive content analysis. ResultsThe analysis generated three main categories: “Organisation,” “Barriers and facilitators,” and “Experienced outcome.” The study showed that successfully implementing reporting radiographers required careful planning and preparation due to radiologists' resistance. The radiologists and managers experienced that reporting radiographers contributed to increased service quality and better training of radiographers and resident physicians. Reporting radiographers found the combination of reporting and diagnostic radiography tasks rewarding and challenging simultaneously. ConclusionThe implementation of reporting radiographers in imaging departments in Norway was described as successful, positively impacting service quality, reporting capacity, and quality development. However, preparation and planning are needed to overcome barriers to task-shifting. Implications for practiceThis study shows that with management involvement and careful planning, reporting radiographers contribute to a high-quality imaging service.

Rapid Root Cause Analysis: Improving OBGYN Resident Exposure to Quality Improvement and Patient Safety Curricula.

Introduction Each year, millions of patients in the United States experience harm as a result of the healthcare they receive. One mechanism used by health systems to learn how and why errors occur is root cause analysis (RCA). RCA teams develop action plans to create and implement systemic changes in healthcare delivery in order to prevent future harm. The American Council on Graduate Medical Education (ACGME) recognizes the importance of analyzing adverse events, and it requires that all residents participate in real or simulated patient safety activities, such as RCAs.Often, institutional RCAs necessitate the assimilation of participants on short notice and demand considerable time investment, limiting the feasible participation of graduate medical education (GME) trainees. This presents a gap between ACGME expectations and the reality of resident involvement in patient safety activities. We present the first iteration of a quality improvement project encompassing a three-hour resident physician training course with simulated RCA-experiential learning. The purpose of this project was to produce a condensed, educational RCA experience that adequately trains allGME learners to serve as informed healthcare safety advocates while also satisfying ACGME requirements. Methods The course ("rapid RCA") was conducted during protected weekly academic training. All residents of the San Antonio Uniformed Services Health Education Consortium (SAUSHEC) Obstetrics and Gynecology (OBGYN) residency program who had not previously participated in a real or simulated RCA were required to take the "rapid RCA." Pre- and post-course surveys were completed anonymously to assess baseline knowledge, new knowledge gained from the course, and attitudes toward the course and its importance to resident training. Results Fourteen OBGYN residents attended the "rapid RCA," indicating that 64% (14 out of 22) of the program had no previous experience or opportunity to participate in a real or simulated RCA. Participation in the course demonstrated a significant gain of new knowledge with an increase from 0/14 to 10/14 (71%) residents correctly answering all pre- and post-course questions, respectively (p < 0.001). Additionally, on a Likert scale from 1 to 5, with 5 indicating "expert level," residents indicated they felt more comfortable on patient safety topics after taking the course (mean pre-course score 1.85 to post-course score 3.64,p < 0.001). All participants indicated they would prefer to take the "rapid RCA" as opposed to the only available local alternative option for a simulated RCA, currently offered as a full-day intensive course. Conclusion A meaningful increase in patient safety knowledge and attitudes toward topics covered in an RCA was demonstrated through the implementation of a "rapid RCA" in OBGYN residents. We plan to incorporate this into our annual curriculum to satisfy ACMGE requirements. This format could be adapted for other specialties as applicable.

Evaluation of the Impact of Pharmacist-Driven Physician Naloxone Training on an Inpatient Psychiatric Unit.

The purpose of this study was to evaluate the impact of pharmacist-driven naloxone training of resident physicians as part of discharge prescribing from an inpatient psychiatric unit. This is a prospective pilot study in which psychiatric resident physicians (N = 21) were educated on naloxone administration, prescribing, and counseling. A ten-question survey was designed and delivered immediately pre- and post-training to assess resident knowledge of and comfort with naloxone prescribing. Respondents were asked to rate ten statements on a scale from 1 to 5, with 1 corresponding to "strongly disagree" and 5 corresponding to "strongly agree." The primary objective was to evaluate the impact of training on prescriber knowledge and attitudes using the designed questionnaire. The secondary objective was to assess the difference in naloxone prescribing pre- and post-training implementation. Descriptive statistics and paired t-tests were conducted to assess statistical significance. Prior to training, 11 resident physicians (approximately 50%) agreed or strongly agreed that they felt knowledgeable about naloxone and approximately 70% (n = 15) felt confident identifying patients who would benefit from naloxone at discharge. Only 10% of resident physicians (n = 2) felt comfortable counseling patients on and administering naloxone during an overdose pre-training compared to 100% after training. Thirty-seven patients were discharged and counseled on naloxone use during the study period. Pharmacist-driven naloxone training significantly increased physician knowledge and comfort prescribing naloxone and resulted in an increase in naloxone prescriptions upon discharge from an inpatient psychiatric unit.

Reflection on Improving the Efficiency of Standardized Training for Resident Physicians in Respiratory Medicine

Significant achievements have been made in the standardized training of resident physicians in China, but currently, there are still problems with weak teaching staff, rigid teaching methods, monotonous teaching content, and one-sided assessment indicators in the standardized training of resident physicians in respiratory medicine. The quality of standardized training for resident respiratory physicians can be improved through optimizing the teaching staff, applying new teaching methods to cultivate students' clinical, scientific research, and humanistic comprehensive qualities.

Resident physician training in bedside pleural procedures: A one-year experience at a teaching hospital

Background and objectiveThis study aims to quantify bedside pleural procedures performed at a quaternary teaching hospital describing technical and epidemiological aspects. Materials and methodsThe authors retrospectively reviewed consecutive patients who underwent invasive thoracic bedside procedures between March 2022 and February 2023. Results463 chest tube insertions and 200 thoracenteses were performed during the study period. Most procedures were conducted by 1st-year Thoracic Surgery residents, with Ultrasound Guidance (USG). There was a notable preference for small-bore pigtail catheters, with a low rate of immediate complications. ConclusionBedside thoracic procedures are commonly performed in current medical practice and are significant in surgical resident training. The utilization of pigtail catheters and point-of-care ultrasonography by surgical residents in pleural procedures is increasingly prevalent and demonstrates high safety.

Human dissection for anesthesiology resident training augments anatomical knowledge and clinical skills.

Anatomy is an essential component of clinical anesthesiology. The use of simulated patients and alternative materials, including embalmed human bodies, have become increasingly common during resident physician training due to the deemphasis on anatomical education during undergraduate medical training. In this report, the need for a more extensive review of relevant anatomy for the practice of anesthesiology was addressed by the design, evaluation, and dissemination of a human dissection course for procedural training of anesthesiology residents. The course utilized "freedom art" embalmed human bodies that allowed trainees to perform ultrasound-based regional and neuraxial techniques followed by detailed dissections of critical anatomy. One hundred and four residents participated in workshops and small group discussions and were evaluated using pre- and post-course assessments. A variety of clinical techniques were performed on the bodies, including regional blocks and neuraxial catheter placement. Insertion of peripheral/neuraxial catheters was successful, with dissections demonstrating the expected placement. Assessment scores improved following the course (pre-course mean 52.7%, standard deviation (σ) 13.1%; post-course mean 72.2%, σ 11.6%; t-test p < 0.0001) and feedback highlighted the usefulness and clinical relevance of course content. The ability to correlate ultrasound imaging with subsequent dissections of the "blocked" area and visualization of dye staining was extremely relevant for spatial understanding of the anatomy relevant for the clinical practice of these techniques. This manuscript demonstrates successful implementation of a comprehensive course for anesthesiology resident physicians to address gaps in undergraduate anatomical education and suggests that broader adoption of dissection courses may be beneficial for training anesthesiologists.

First-Person Point-of-View Instructional Video on Lumbar Puncture Procedure.

Tutorial videos filmed from a first-person point of view (FP-POV) are generally well received. Pediatric residents are expected to be competent in performing the lumbar puncture (LP). The educational effectiveness of a FP-POV in lumbar puncture procedure training for resident physicians has yet to be evaluated. We compared a FPPOV LP video with a standard in-person demonstration of the LP. We designed an assigned cohort study to compare a FP-POV procedural instructional video of a simulated pediatric LP to the standard in-person procedure demonstration.After the intervention, residents completed an LP observed by one of two blinded reviewers who assessed the procedure using a modified, published assessment tool.Participants completed preintervention and postintervention surveys to rate self-confidence and usefulness of the FP-POV educational method. The data was analyzed using a Wilcoxon Rank sum test. z Scores were calculated on the raw assessment scores. Eighteen first year pediatric residents participated, nine in each group. The median modified assessment tool score was 17 in the FP-POV group (min, 14; max, 17; IQR:, 1.5) and 14 in the standard demonstration group (min, 6; max, 17; IQR, 4.5), with the higher score being more successful. There was a statistical difference between the assessment scores between the 2 groups (z score = 2.18, P = 0.04). Postintervention survey data demonstrated relative satisfaction with the FPPOV educational method. This study supports the educational effectiveness of a FP-POV procedure tutorial.Future studies with a larger sample size are needed.

Finding compassion when compassion fatigued.

Objective: The unrelenting turmoil of the COVID-19 pandemic has been especially hard on those in the healthcare field. This chronic stress has resulted in depleted compassion towards patients served and colleagues. Researchers have suggested that empathy is a finite resource that must be replenished. For physicians in residency training and those in practice, where finding meaning and purpose in their work is already a challenge, the spark for medicine and helping others may easily become extinguished.This article explores interventions implemented in two family medicine residency programs to addressconcerns about burnout and compassion fatigue exacerbated by the COVID-19 pandemic.Methods: A qualitative research approach is employed here through case studies of two family medicine programs, along with a description of several interventions intended to mitigate burnout and compassion fatigue during the pandemic.Participants were 36 family medicine residents from "residency #1" and 36 family medicine residents from "residency #2."Results: The authors describe several interventions used in the two residency programs to reduce issues of compassion fatigue. These include meditation, gratitude practice, guided group support, and a focus on clinicians' physical health.Feedback from residents and program leaders suggest that these interventions were useful tools to help physicians navigate their new normal as they began to practice during a pandemic, thereby reducing burnout and challenges with compassion fatigue. A strategic plan is outlined to help other programs implement some of these strategies.Conclusions: It is imperative that training programs continue to implement interventions that emphasize resident and post-residency wellness to reduce compassion fatigue in order to navigate the new stressors that came with the COVID-19 pandemic and those that will come with pandemics in the future.

Study on a job competence evaluation system for resident physicians (including integrated postgraduates) receiving standardized training

BackgroundStandardized training for resident physicians is the primary form of postgraduate medical education, and it plays a pivotal role in healthcare safety and industry stability. Currently, it has garnered significant attention from healthcare institutions.MethodsBy conducting a comprehensive literature review and a Delphi consultation in June 2022 for which 40 experts in clinical medicine, public health, and other related fields in China were invited. The indicators were adjusted according to the results of the consultation, and the final indicator weights were determined through an analytic hierarchy process.ResultsThe response rate was 100%, and the expert authority coefficient was 0.879. The consistency among the experts on the tertiary indicators, as measured by Kendall’s W, was 0.675 (χ2 = 42.516, p < 0.001). Based on the results of the expert consultation, a job competence evaluation system for resident physicians (including integrated postgraduates) receiving standardized training was established, which included 6 primary indicators, 18 secondary indicators, and 116 tertiary indicators. The weights for the primary indicators, namely professional quality, skills and knowledge, patient care, communication and collaboration, teaching skills, and lifelong learning, were 0.313, 0.248, 0.181, 0.083, 0.066, and 0.110, respectively. The top three secondary indicators in terms of combined weights were clinical skills (0.122), professional ethics (0.120), and professional dedication (0.109). The three tertiary indicators with the highest scores were “maintains collaboration with peers and colleagues in patient treatment,” “has clinical thinking skills, makes diagnosis and treatment decisions based on analysis of evidence, and has the ability to administer suitable treatments,” and “abides by laws and discipline and refuses to seek personal gains in medical practice”; their combined weights were 0.035, 0.028, and 0.027, respectively.ConclusionThis study has established a concrete, objective, and quantifiable competency assessment index system for standardized training of clinical resident physicians (including integrated postgraduates). This system provides a foundation for the quantitative evaluation of the competency of clinical resident physicians (including integrated postgraduates) undergoing standardized training.

Survey on the working, training, and research conditions of resident physicians in internistic and rheumatological continuing education-BEWUSST.

Data on the training and continuing education situation of residents in the field of internal medicine and rheumatology are not available for Germany. For this reason, the Commission for Education and Training of the German Society of Rheumatology (DGRh) initiated the BEWUSST survey on the working, training and research conditions of residents in rheumatology. A total of 102 questions on the topics of working conditions in everyday professional life, continuing medical education and training, compatibility of career and family, compatibility of work and research, perspectives as arheumatologist and practical activities were included in an online questionnaire. Atotal of 102participants took part in the survey. Of the respondents 48.1% were satisfied with their professional situation, 40.2% of the participants were supervised by aspecialist mentor and 54.9% were working as scientists during their work as aphysician.A compatibility of family and career was possible for 34.7%. After completion of the residency 52.9% of the respondents aspired to acombined clinical and outpatient activity. Half of the trainee rheumatologists are satisfied with their professional activities, although mentoring of the assistants in training should be further improved. With respect to the desired combined clinical and outpatient activity, the existing options should be expanded or new professional fields of activity should be established, so that the specialty remains attractive for the upcoming generations.

Thoughts of Courses Construction of Graduate Student with Master of Medicine Based on Online Open Courses

Under the “double-track integration” training model, there are problems with short learning time, scattered locations, and inconsistent schedules for master of medicine. The traditional method of face-to-face teaching in a centralized setting cannot meet the new training requirements. The standardized training for resident physicians strictly requires a 33-month period for clinical skills training. How can we reform the teaching methods while maintaining the same length of the curriculum, in order to balance the standardized training for resident physicians and course learning? Online open courses have the characteristics of fragmented knowledge, abundant resources, diverse formats, flexible choices, and unrestricted learning time and location. They can effectively resolve the conflict between course learning and standardized training for master of medicine under the “double-track integration” training model. How to successfully develop online courses has become a key issue in the reform of course teaching for master of medicine. Based on the experience of course teaching management for master of medicine, this article discusses some considerations for the construction of online open courses.
