Impact of COVID-19 pandemic on physical health amongst children: Difference-in-differences analyses of nationwide school health checkup database.

INTRODUCTION: The COVID-19 pandemic posed tremendous challenges for children. However, the long-term effects of the pandemic on various aspects of physical health at a national level remain unclear. METHODS: In this retrospective cohort study, we analysed data from nationwide health checkup records amongst children aged 7-15 years. The dataset comprised 3 544 146 records from 393 794 individuals who graduated from junior high school during fiscal years 2007 to 2022. Difference-in-differences (DID) analyses with multiple time periods were used to examine the impact of COVID-19 on physical health outcomes. RESULTS: Compared with the pre-pandemic period, the COVID-19 pandemic was associated with excess increases in obesity for boys and girls, persisting over the 3 years (+0.42%; [95% CI, 0.23-0.61]). Also, it was associated with excess increases in underweight (+0.28% [0.25-0.32]) and poor visual acuity amongst boys in the 3rd year (+1.80% [1.30-2.30]). There were excess reductions in dental caries (-1.48% [-2.01 to -0.95]), glucosuria (-0.55 [-0.88 to -0.23]) and hematuria (-0.43% [-0.73 to -0.13]) during the 3rd year of the pandemic. CONCLUSIONS: These findings underscore the multifaceted impact of the pandemic on various health indicators for school-aged children. This information could be valuable for public health policy and paediatric healthcare planning in the post-pandemic era.

Performance of Cardiovascular Physical Exam Skills by Internal Medicine Residents.

OBJECTIVE: Few studies have assessed the ability of internal medicine residents to perform a cardiovascular physical examination using real patients. METHODS: First year internal medicine interns from two large academic medical centers in Maryland examined the same patient with aortic insufficiency as part of the Assessment of Physical Examination and Communication Skills (APECS). Interns were assessed on five clinical domains: physical exam technique, identifying physical signs, generating a differential diagnosis, clinical judgement, and maintaining patient welfare. Spearman's correlation test was used to describe associations between clinical domains. Preceptor comments were examined to identify common errors in physical exam technique and identifying physical signs. RESULTS: One-hundred and nine interns examined the same patient with aortic insufficiency across 14 APECS sessions. Only 58 interns (53.2%) correctly identified the presence of a diastolic murmur, and only 52 interns (47.7%) included aortic insufficiency on their differential diagnosis. There was a significant and positive correlation between physical exam technique and identification of the correct physical findings (r=0.42, p<0.001). Both technique (r=0.34, p=0.003) and identifying findings (r=0.42, p<0.001) were significantly associated with generating an appropriate differential diagnosis. Common errors in technique included auscultating over the gown, timing the cardiac cycle with the radial pulse, and failing to palpate for the apical impulse. CONCLUSIONS: Internal medicine interns had variable skills in performing and interpreting the cardiovascular physical exam. Improving cardiovascular exam skills would likely lead to increased identification of relevant cardiovascular findings, inform clinical decision making and improve overall patient care.

Shoulder External Over Internal Rotation Ratio Is Related to Biomechanics in Collegiate Baseball Pitching.

Altering baseball pitching mechanics affects both performance and the risk of injury. The purpose of this study is to investigate the relationships of shoulder external over internal rotation ratio (SEIR) and other shoulder rotational properties during physical exam and biomechanics of pitching for 177 collegiate baseball pitchers. The shoulder range of motion was quantitatively measured using a custom-made wireless device. Pitching motion data were collected at 240 Hz, and a custom program was created to calculate the throwing arm motion and loading during baseball pitching. Linear regression and analysis of variance tests were performed to investigate the relationships between the shoulder physical exam outcomes and throwing arm biomechanics. SEIR had significant correlations with shoulder horizontal adduction angle at foot contact, maximum shoulder external rotation angle, maximum shoulder linear velocity, and elbow angle at ball release. SEIR groups had significant differences in shoulder proximal force, adduction torque, internal rotation torque, and horizontal adduction torque, and in elbow medial force and varus torque. Glenohumeral internal rotation deficit and total rotational motion deficit had no relationships with throwing arm motions or joint loadings. Shoulder health should be monitored to improve understanding of pitching mechanics in collegiate baseball pitchers.

The Ultrasound Hepato-Jugular Reflux: Measuring the Hepato-Jugular Reflux with Ultrasound with Comparison to Invasive Right Heart Catheterization.

BACKGROUND: Ultrasound can overcome barriers to visualizing the internal jugular vein, allowing hepato-jugular reflux and jugular venous pressure measurement. We aimed to determine operating characteristics of the ultrasound hepato-jugular reflux and ultrasound jugular venous pressure predicting right atrial and pulmonary capillary occlusion pressures. METHODS: In a prospective observational cohort at three US academic hospitals the hepato-jugular reflux and jugular venous pressure were measured with ultrasound before right heart catheterization. Receiver operating curves, likelihood ratios, and regression models were utilized to compare the ultrasound hepato-jugular reflux and ultrasound jugular venous pressure to the right atrial and pulmonary capillary occlusion pressures. RESULTS: In 99 adults undergoing right heart catheterization, an ultrasound hepato-jugular reflux had a negative likelihood ratio of 0.4 if 0 cm and a positive likelihood ratio of 4.3 if ≥ 1.5 cm for predicting a pulmonary capillary occlusion pressure ≥ 15 mmHg. Regression modeling predicting pulmonary capillary occlusion pressure was not only improved by including the ultrasound hepato-jugular reflux (P < .001), it was the more impactful predictor compared with the ultrasound jugular venous pressure (adjusted odds ratio 2.6 vs 1.2). The ultrasound hepato-jugular reflux showed substantial agreement (kappa 0.76; 95% confidence interval, 0.30-1.21), with poor agreement for the ultrasound jugular venous pressure (kappa 0.11; 95% confidence interval, -0.37-0.58). CONCLUSION: In patients undergoing right heart catheterization, the ultrasound hepato-jugular reflux is reproducible, has modest impact on the probability of a normal pulmonary capillary occlusion pressure when 0 cm, and more substantial impact on the probability of an elevated pulmonary capillary occlusion pressure when ≥ 1.5 cm.

Development and Evaluation of a Wearable Simulator System.

Background: Peer physical examination is a clinical teaching-learning approach used for decades because of the convenient sample of peers for practicing. However, this approach has limitations when learning to assess abnormalities and threatens psychologically safe learning. A wearable simulator system was designed for learning physical examination skills to minimize ethical and learning challenges. Sample: The sample consisted of fifty prelicensure nursing students and ten faculty in an upper Midwest university. Method: The wearable simulator was constructed into a vest with RFID tags and ribcage landmarks. An observational, evaluative design was used for participants to rate seven categories during a one-hour evaluation session of the wearable simulator worn by a standardized patient trained to portray an individual with pneumonia. Results: Satisfaction was rated highly among participants. More than 80% of student participants indicated the wearable simulator promotes privacy and reduces embarrassment. Conclusion: The wearable simulator system offers a promising teaching-learning alternative with scenario-specific auscultation and palpation feedback to provide a safe, repeatable, and consistent simulation experience.

A different approach to teaching pre-clerkship students physical diagnosis: standardized patient instructor-senior medical student teaching teams.

BACKGROUND: Faculty have traditionally taught the physical examination (PE) to novice medical students (pre-clerkship students.), despite recruiting and cost issues and problems standardizing their approach. ACTIVITY: We present a model using standardized patient instructor (SPI)-fourth year medical student (MS4) teams to teach PE to pre-clerkship students, leveraging the benefits of co-teaching and peer-assisted learning. RESULTS: Surveys of pre-clerkship students, MS4s and SPIs indicate positive perceptions of the program, including MS4s reporting significant growth in their professional identities as educators. Pre-clerkship students' performance on the spring clinical skills exams was equivalent to or better than their peer performance pre-program implementation. IMPLICATIONS: SPI-MS4 teams can effectively teach novice students the mechanics and clinical context of the beginners' physical exam.

Beyond the Usual Suspects: Hereditary Hemochromatosis and Transaminitis in Primary Care.

An annual physical examination within a primary care setting, including evaluation of liver enzymes and abnormal serology, is incidental and often asymptomatic. Fatty liver is the most common etiology for transaminitis. Hepatobiliary imaging studies, viral hepatitis serology, evaluation of metabolic liver disease, and alcohol consumption history should be performed for transaminitis evaluation. In patients with prior history of excessive alcohol consumption, transaminitis is often assumed to be alcohol-related. It is prudent to evaluate other infectious and metabolic etiologies, which can change patient management. Iron studies, including ferritin and transferrin saturation, are performed to evaluate hereditary hemochromatosis (HH). We present the case of a 46-year-old patient who visited the clinic for a routine health checkup, during which elevated ferritin levels were detected. Subsequent diagnosis revealed hemochromatosis. The patient underwent phlebotomy, resulting in a reduction of ferritin levels.

Pediatric Murmurs.

Many healthy children may be found to have a murmur on physical exam. Whether this murmur is discovered at a routine health maintenance visit or as a result of a focused exam on a child with illness, it is just one finding and must be considered in the context of the child's history and other physical exam findings. Murmurs associated with heart defect or dysfunction occur most often in infancy. Most murmurs discovered in children, especially after infancy, between ages 3 to 6 and in young-adulthood, are innocent or benign murmurs and less likely a symptom of cardiac dysfunction or defect.

A Case of Hand-Foot-and-Mouth Disease in an Adult Male.

Hand-foot-and-mouth disease (HFMD) is commonly seen in infants and children; less frequently, it may be seen in adults as well. The disease is usually associated with viral infections, including many variants of enteroviruses and coxsackieviruses. We discuss the case of a 39-year-old male who presented with constitutional symptoms, fever, and lesions on his hands, feet, and mouth. His children, who had been recently diagnosed with HFMD, were likely the source of his infection. A comprehensive history and physical examination enabled us to identify the lesions, some of which were faint and difficult to visualize. Viral panel testing indicated positive results for human rhinovirus/enterovirus. Treatment and testing associated with the patient's condition were supportive, largely based on the history and physical findings which helped us narrow down our differential diagnoses. Complete resolution of the symptoms within one to two weeks is generally expected in these patients.

Internal medicine intern performance on the gastrointestinal physical exam.

OBJECTIVES: The gastrointestinal (GI) physical exam provides critical information about underlying disease states. However, since assessment of physical examination skills is rarely conducted as part of internal medicine residency training, little is known about resident performance on the GI physical exam. METHODS: During a clinical skills assessment that took place between November 2019 and February 2020, internal medicine interns examined the same patient with chronic liver disease while being observed by faculty preceptors. We compared the exam maneuvers performed with those expected by the faculty evaluators. We noted which maneuvers were performed incorrectly, whether physical exam technique correlated with identification of physical exam findings, and if performance on the physical exam was associated with building an appropriate differential diagnosis. This four-hour assessment was required for internal medicine interns within two different residency programs in the Baltimore area. RESULTS: More than half of the 29 participating interns (n=17, 58.6 %) received a "needs improvement" score on their physical exam technique. Technique was highly correlated with identifying the correct physical signs (r=0.88, p<0.0001). The most commonly excluded maneuvers were assessing for splenomegaly and hepatomegaly. The most commonly missed findings were splenomegaly and hepatomegaly. Most interns included chronic liver disease as part of their differential diagnosis even if they received "needs improvement" scores on physical exam technique or identifying physical signs. CONCLUSIONS: Internal medicine interns would benefit from learning an organized approach to the gastrointestinal exam. This would likely lead to increased identification of important gastrointestinal findings.

Attitudes and Factors Determining the Practice of Routine Medical Checkups in the People of Rawalpindi, Pakistan: A Cross-Sectional Study.

INTRODUCTION: Routine medical checkup (RMC) is a screening and preventive technique that is implied to detect non-communicable diseases (NCDs). This study aims to assess the awareness in public regarding RMC, the association between education level and level of familiarity regarding RMC, and factors that prevent and encourage the practice of RMC by the public. METHODS: This is a cross-sectional study carried out in Rawalpindi, Pakistan. Health professionals and individuals who refused to consent were excluded from the study. Data was collected using a mixed-mode questionnaire, and convenient sampling was used. The sample size was calculated to be 355 according to the WHO sample size calculator. A total of 356 individuals participated in this study after giving informed consent. Both male and female adults aged 18 or older and residents of Rawalpindi were included in the study. Individuals younger than 18 were excluded.  Results: Among the 356 study participants, 160 (45%) were males, and 196 (55%) were females. The mean age was 27.57±10.027. Among the total participants, 33 (9.3%) individuals had primary-level education, 100 (28.1%) individuals had secondary-level education, and 233 (62.6%) had graduate-level education. A total of 329 (92.9%) participants knew that RMCs could help in early diagnosis and treatment. On the contrary, only 154 (43.3%) people knew that RMCs involve screening all body tissues. Only 329 (92.4%) participants said that they were aware that timely diagnosis through RMC can lead to early treatment. Graduates were generally more aware of different aspects of RMCs, especially in the domains of awareness regarding what an RMC is and that RMC can help in timely diagnosis compared to participants who had primary or secondary level of education (p<0.001). Females had a greater overall awareness of RMCs than males (p<0.001). Graduates were more likely to undergo RMCs than people educated till the primary or secondary level (p<0.001). The most common reason for undergoing RMC was "just concerned about health," which was selected by 130 (36.5%) participants. The most common reason mentioned by participants for not having an RMC was ''heavy cost,'' mentioned by 104 (29.2%) participants.  Conclusion: Most of the participants of this study were well educated and were students in terms of profession. The majority of the study population knew that RMCs could help in early diagnosis and treatment. Awareness regarding RMCs was linked to educational level. Females had overall better knowledge regarding RMCs than men. The most common reported reason to have an RMC was a health concern, and the most common reported reason for not having an RMC was its high cost.

A Visual Diagnosis: Lipodystrophy.

Lipodystrophy syndromes are rare metabolic disorders characterized by local or generalized loss of adipose tissue, resulting in insulin resistance, dyslipidemia, and cosmetic disfiguration. The lipodystrophic phenotype is highly variable, with partial lipodystrophy often missed or misdiagnosed as other diseases from a lack of a proper physical examination and low physician awareness. Correct diagnosis is important for optimal treatment and follow-up strategies in these patients. The use of GLP-1 analogs has not been systematically evaluated in lipodystrophy and could be a potential precision medicine therapy. We aim to make the reader, particularly generalists or endocrinologists outside of tertiary referral centers, aware of the presentation and clinical features of partial lipodystrophy, emphasize the role of a full physical examination in diagnosis, and discuss therapeutic options, including GLP-1-based glycemic management illustrated by our clinical case.

A Case Report of Culture-Negative Necrotizing Fasciitis With Low Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) Score: A Diagnostic Dilemma.

The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score is a diagnostic tool used to help clinicians identify necrotizing fasciitis (NF) in its early stages. This tool uses six laboratory values including the patient's white blood cell count, C-reactive protein level, serum sodium level, creatinine level, and hemoglobin level to help with risk stratification. Each of these laboratory values is assigned a point value and the total score is used to determine the likelihood that a patient has NF, with a score of 6 or higher considered to be strongly indicative. The LRINEC score has gained popularity in recent years, having been included in guidelines and society recommendations for the management of NF. However, some studies have challenged the validity of the LRINEC score. Prompt and accurate diagnosis of NF is imperative given the associated mortality rate, which can be as high as 30%-40%, especially if the diagnosis is delayed. We present a case of a patient with a delayed diagnosis of NF that was initially missed in the early stages in the setting of a low LRINEC, however, growing clinical suspicion eventually led to an accurate diagnosis and management.

Resumo: Objetivou-se desenvolver o protótipo de um software para avaliação clínica de enfermeiros, no serviço de saúde da penitenciária federal de segurança máxima de Porto Velho, Brasil. Como método, seguiram-se os moldes da pesquisa metodológica de produção tecnológica, que teve como cenário uma penitenciária federal, e foi desenvolvida em duas fases: fase 1, denominada fase exploratória, que incluiu três etapas: a) revisão de literatura; b) informações obtidas dos participantes sobre o conhecimento da avaliação clínica; c) análise dos dados; fase 2, denominada de fase de desenvolvimento do modelo de prototipação, o qual seguiu o ciclo de vida de desenvolvimento de sistema, dividido em três etapas: análise e especificação; desenvolvimento; e manutenção, propostas por Pressman (2011). Como produto, obteve-se o protótipo do software intitulado AVALIA TIS - SPF, com características dinâmicas que inclui módulos de cadastro e login do usuário; identificação do paciente; histórico/anamnese e avaliação clínica. Conclui-se que esta ferramenta tem potencial para instrumentalizar o enfermeiro na execução e documentação da primeira etapa do processo de enfermagem, contribuindo na valorização e sustentação da prática profissional, colaborando para a assistência integral da população carcerária. É viável a replicabilidade para outras unidades prisionais, temas e outras áreas do conhecimento. Tem potencial para impacto social, mantendo a população de pessoas privadas de liberdade, com melhor qualidade de vida durante o período do cumprimento de pena; impacto econômico, com possibilidade de identificação precoce de problemas de saúde e, consequentemente, menor número de complicações que exigem utilização de serviços de saúde de atenção secundária ou terciária. O teor inovador encontra-se no fato de implementar um sistema de informação segura dos dados dos custodiados, com possibilidade de ampliação de todas as penitenciárias de segurança máxima brasileiras.

Abstract: This study aimed to develop a software prototype to clinically evaluate nurses in the health service of the maximum-security federal penitentiary in Porto Velho. We followed the methodological research of technological production using a federal penitentiary as a scenario. The study consisted of two phases: Phase 1, the exploratory phase, which included three stages: a) literature review; b) the information obtained from participants regarding their knowledge of clinical evaluation; and c) data analysis; Phase 2, the prototyping model development phase, which followed the system development life cycle, divided into three stages: a) analysis and specification; b) development; and maintenance, proposed by Pressman (2011). The final product is a software prototype entitled AVALIA TIS - SPF, with dynamic characteristics that include user registration and login modules, patient identification, history/anamnesis, and clinical evaluation. In conclusion, this tool has the potential to equip nurses in the execution and documentation of the first stage of the nursing process, contributing to the appreciation and support of professional practice and collaborating for the integral assistance of the prison population. Replicability for other prison units, themes, and other areas of knowledge is feasible. It has the potential for social impact, giving a better quality of life to the freedom-deprived population while serving their sentence, and economic impact, with the possibility of early identification of health problems and, consequently, fewer complications that require secondary or tertiary health care services. The innovative content is because it implements a secure information system for the data of those in custody, with the possibility of expanding all Brazilian maximum security penitentiaries.

Exame físico em ginecologia / Physical examination in gynecology

O exame físico na prática ginecológica diuturna é o sustentáculo de uma perspectiva diagnóstica com vistas a uma abordagem individualizada, oportuna e humanizada da paciente. Lança mão de técnica semiótica clássica, inicialmente, após avaliação de sinais vitais, minuciosa inspeção ectoscópica, seguida de exame físico especial. E deverá ser realizado em ambiente adequadíssimo, sem nenhuma improvisação e ou adaptações não compatíveis, com a importância e a segurança garantidas por um exame físico de boa qualidade. O exame físico de mamas tem como objetivo primordial a identificação de nódulos mamários e, eventualmente, de tumores localmente avançados; e relativa tranquilidade é assegurada às pacientes quando ele é considerado normal. O exame físico vulvar permite a identificação de prolapso de órgãos pélvicos, neoplasia intraepitelial e/ou invasiva vulvar e distúrbios de desenvolvimento sexual, além de oferecer subsídios para a propedêutica da vulvodínea, sendo, principalmente, uma oportunidade para o diagnóstico em dermatologia vulvar, mesmo a vulva correspondendo a apenas 1% da pele feminina. O exame especular, um clássico da ginecologia, é indispensável para a triagem do câncer de colo uterino. Por fim, o toque genital, a despeito de sua subjetividade, permite a avaliação dos órgãos genitais internos.

Physical examination in daytime gynecological practice is the mainstay of a diagnostic perspective with a view to an individualized, timely and humanized approach to the patient; resorting to the classical semiotic technique, initially, after assessing vital signs, a thorough ectoscopic inspection, followed by a special physical examination; which should be carried out in a very suitable environment, without any improvisation or adaptations that are not compatible with the importance and safety guaranteed by a good quality physical examination. The primary objective of the physical examination of the breasts is to identify breast nodules and possibly locally advanced tumors; in addition to relative tranquility, assured to patients, when the respective exam is considered normal. Vulvar physical examination allows the identification of pelvic organ prolapse; vulvar intraepithelial and/or invasive neoplasia; sexual development disorders; in addition to offering subsidies for the propaedeutics of vulvodynia; and, above all, it is an opportunity for diagnosis in vulvar dermatology, even though the vulva accounts for only 1% of female skin. Specular examination, a classic in gynecology, is essential for screening for cervical cancer. Finally, the genital touch which, despite its subjectivity, allows the evaluation of the internal genital organs.

ADEPT-CARE: A pilot, student-led initiative to improve care for persons with disabilities via a novel teaching tool.

BACKGROUND: Over one-quarter of United States adults live with a disability. Despite persistent ableism, defined as discrimination and prejudice against people with disabilities, in healthcare, disability-focused training remains largely absent from medical education. OBJECTIVE: The aim of this study was to pilot and evaluate a novel teaching mnemonic (ADEPT-CARE) for performing a comprehensive history and physical exam for disabled patients. METHODS: In Spring 2022, first-year medical students at a suburban Mid-Atlantic institution could electively participate in a learning module that included ADEPT-CARE. Surveys were administered to students before and following exposure to the ADEPT-CARE protocol. RESULTS: Of 142 eligible students, 33 and 21 completed the pre- and post-surveys, respectively. The ADEPT-CARE protocol made sense to 95.2% of students. All (100%) students reported that they will use the ADEPT-CARE protocol in the assessment of patients with disabilities. Students were more likely to agree or strongly agree that they had a consistent approach or strategy in mind when assessing a patient with a disability after exposure to ADEPT-CARE (85.7% vs. 39.4%, respectively, p = 0.002). There was no statistically significant difference in students' perceived confidence in their ability to assess a patient with a disability after curriculum completion compared to before (85.7% vs. 81.8%, respectively, p = 1.0). CONCLUSIONS: The ADEPT-CARE protocol has the potential to be an effective teaching tool by providing a framework to equitably care for disabled patients. Future research should assess whether students' self-reported increased confidence and intention to utilize ADEPT-CARE translates into the clinical setting.

Clinical Evaluation of the Knee Arthritis Patient.

The evaluation of a patient with knee osteoarthritis (OA) has 3 main components: clinical history, physical examination, and radiographic imaging. The clinician should assess for inciting and aggravating factors for the knee pain as well as for the presence of any mechanical symptoms. A history of prior knee injury or surgery can suggest the development of early osteoarthritis. A thorough physical examination of the knee should be performed. Some features of OA include limited range of motion, crepitus in the patellofemoral compartment, and joint line tenderness. Depending on the severity of OA varus or valgus alignment can develop. Special tests such as the McMurray for meniscal tears may cause increased pain as patients with OA will often have degenerative meniscal tears. Weight bearing radiographs can confirm the diagnosis of OA. Several scales exist to grade the severity of OA with the Kellgren-Lawrence being one that is often used. Radiographic features of OA include joint space narrowing, osteophytes, sclerosis of bone and bone end deformities. If after the above evaluation the diagnosis is still unclear, advanced imaging or laboratory testing can be performed to evaluate for alternative diagnoses.

Learning abnormal physical examination signs: an introductory course.

CONTEXT: The acquisition of clinical skills is an essential part of the osteopathic medical school curriculum. Preclinical medical students, especially at osteopathic medical schools, have limited exposure to abnormal physical examination (PE) findings that are not typically seen in a student's peers or in a standardized patient (SP). The early exposure of first-year medical students (MS1s) to normal and abnormal findings in the simulation settings better equips them to identify abnormalities when they encounter them in a clinical setting. OBJECTIVES: The aim of this project was to develop and implement the introductory course on learning abnormal PE signs and pathophysiology of abnormal clinical findings to address the educational needs of MS1s. METHODS: The didactic part of the course consisted of PowerPoint presentations and lecture on the topics related to the simulation. The practical skill session was 60 min, during which time students first practiced PE signs and then were assessed on their ability to accurately identify abnormal PE signs on a high-fidelity (HF) mannequin. Faculty instructors guided students through clinical cases and challenged them with probing questions in clinically relevant content. Before- and after-simulation evaluations were created to assess students' skills and confidence. Student satisfaction levels after the training course were also assessed. RESULTS: This study demonstrated significant improvements in five PE skills (p<0.0001) after the introductory course of abnormal PE clinical signs. The average score for five clinical skills increased from 63.1 to 88.74% (before to after simulation). The confidence of students in performing clinical skills and their understanding of the pathophysiology of abnormal clinical findings also increased significantly (p<0.0001) after simulation activity and educational instruction. The average confidence score increased from 3.3 to 4.5% (before to after simulation) on a 5-point Likert scale. Survey results demonstrated high satisfaction with the course among learners with mean satisfaction score 4.7 ± 0.4 on 5-point Likert scale. The introductory course was well received by MS1s and they left positive feedback. CONCLUSIONS: This introductory course offered MS1s with novice PE skills the ability to learn a variety of abnormal PE signs, including heart murmurs and rhythms, lung sounds, measurement of blood pressure (BP), and palpation of the femoral pulse. This course also allowed abnormal PE findings to be taught in a time-efficient and faculty-resource-efficient manner.

Peer-Assisted Learning in a Longitudinal Hybrid Physical Exam Course.

Peer-assisted learning (PAL) improves teaching skills and self-confidence for instructors and creates a supportive learning climate for learners. We developed a PAL hybrid teaching structure for our physical exam course by partnering upper-level peer instructors with faculty co-instructors and evaluated its impact on upper-level student peer instructors and first-year student learners using quantitative and qualitative methods. The PAL component of the hybrid teaching structure was perceived to have important benefits for all and salient limitations for student learners. The hybrid nature of the course provided a unique vantage point for evaluation of PAL and we theorize that faculty co-instructors may balance some of the perceived limitations of PAL.
