3D Printed Cardiac Models as an Adjunct to Traditional Teaching of Anatomy in Congenital Heart Disease-A Randomised Controlled Study.

INTRODUCTION: Three-dimensional (3D) printed cardiac models are increasingly being used for medical education, simulation and training, communication, surgical planning and research. Given the complexities of congenital cardiac anatomy, 3D printing is well suited as an adjunct to traditional teaching methods. This study aims to explore the influence of 3D printed cardiac models as a teaching aid for nurses and paediatric trainees. We hypothesise that using 3D models as an adjunct to didactic teaching methods improves knowledge and confidence levels of participants, regardless of their cardiology experience. METHOD: A prospective randomised study was performed recruiting paediatric nurses and doctors at a tertiary paediatric hospital. All participants undertook traditional congenital cardiac teaching describing normal cardiac anatomy and seven congenital lesions of increasing complexity (atrial septal defect, ventricular septal defect, vascular ring, partial anomalous pulmonary venous return, tetralogy of Fallot, transposition of the great arteries, and double outlet right ventricle). The intervention group received an additional recorded demonstration while handling 3D printed models of a normal heart and the same lesions. Pre- and post-intervention assessments were completed using a subjective Likert-scale questionnaire and objective multiple-choice examination. RESULTS: A total of 73 health practitioners (30 cardiac nurses and 43 paediatric trainees) were included. Subjective knowledge and confidence levels substantially improved in the intervention group (both p<0.001), with no differences observed in the control group. Greater improvement in both subjective and objective post-test scores was observed in the intervention group. A pronounced difference between pre- and post-teaching objective examination scores was found in both groups (p=0.002), with larger improvements observed in the intervention group. The mean score in the intervention group after teaching increased by 4.27 (21.4% improvement), as opposed to 2.28 (11.4% improvement) in the control group. There was no difference in pre-test score or post-test improvement based on previous cardiology experience. DISCUSSION: Three-dimensional (3D) printed cardiac models, when used as an adjunct to traditional teaching methods, substantially improve knowledge and confidence levels of health professionals on a range of congenital cardiac lesions. These models enhance the learners' educational experience and understanding of cardiac anatomy by overcoming the limitation of two-dimensional representations of 3D structures.

Virtual Models Using Augmented Reality May Provide a Suitable Supplement, Although Not a Physical Specimen Replacement, in Pathology Education.

There is a growing trend towards using virtual models within medical programs. In some disciplines, the use of human samples or cadavers is increasingly being replaced by technology-enhanced modes of delivery. Although this transition can occur with some success, the impact of virtual representations to replace depictions of disease states from dissected samples displayed in acrylic pathological specimen jars has never been investigated. This study assessed medical student perceptions of replacing teaching through physical specimens (i.e. specimen jars or real tissue) with virtual models across cardiovascular, neural, musculoskeletal, haematology, endocrine and immunological pathology curricula. Seventy-four year 2 (n = 31) and year 5 (n = 43) medical students participated in the study. After being provided with a demonstration of a potential tablet-based lesson on lung pathology using augmented reality, participants completed a Likert-scale survey and provided written feedback. Questions requested thoughts on the usefulness of the 3D-virtual model compared to physical specimens and whether current teaching in pathology could be replaced by technology-enhanced practices. Most students (58.15%) disagreed on the replacement of physical specimens with virtual models. Furthermore, over half the students (55.4%) indicated that the replacement of physical specimens with augmented reality models would not be beneficial for pathology learning. Nearly two-thirds of students believed that the absence of physical specimens would negatively impact their knowledge. Nonetheless, many students would appreciate the opportunity to revise pathology away from the labs with virtual options. As such, an overwhelming number of students (89.2%) would prefer having both physical specimens and virtual models for learning. This study identifies that technology-enhanced learning may be a suitable supplement alongside traditional hands-on teaching but should not replace the use of pathological specimens within a medical curriculum.

The development of a novel, multilingual IBD knowledge questionnaire for Asian patients with inflammatory bowel disease.

BACKGROUND: Inflammatory bowel disease is an uncommon disease in developing nations whereby patient's knowledge on the disease may be limited. The CCKNOW questionnaire, a widely known questionnaire to assess patient's knowledge on the disease, may be too complex to comprehend for patients in developing countries. The aim of this study is to develop a new tool known as AIBDKQ questionnaire to evaluate the local inflammatory bowel disease patient's knowledge. METHODS: This was a prospective study carried out in four phases. In phase 1, three gastroenterologists with expertise in IBD generated a total of 21 questions related to the general knowledge of the disease in the English language. Phase 2 involved content and face validity whereby the questions were further validated by other gastroenterologists. In phase 3, the validated questions were translated into three languages namely Malay, Mandarin and Tamil which are commonly used in Malaysia. In phase 4 (statistical validity), administration of the questionnaires to patients and hospital staff were conducted to assess the construct validity, discriminative ability, predictive validity and reliability of the questionnaires. RESULTS: A total of 21 questions were generated initially. Further evaluation indicated that 20 items had adequate kappa and content validity index for relevance (CVI: 0.714 to 1, Kapp: 0.645 to 1) and clarity (CVI: 0.714 to 1, Kapp: 0.645 to 1). The questionnaires in four languages were administered to 213 patients to assess the construct validity. Six items were removed (three for low communality, one for small loading factors, two for cross loading), resulting in 16 final questions. Assessment with 34 hospital staff involving nurses, doctors and clerks showed significant differences in knowledge between the groups (F = 14.007, p < 0.001) and were able to discriminate doctors from nurses and clerks. Another group of 18 hospital staff administered with AIBDKQ and CCKNOW questionnaires showed a Pearson's correlation coefficient of 0.8 indicating strong correlation and concurrent predictive validity between the two questionnaires. Final assessment with 38 patients for reliability assessment revealed high intraclass correlation of the questionnaire among the four languages. CONCLUSIONS: The AIBDKQ has an excellent discriminant ability and internal consistency with a strong correlation when compared to the standard CCKNOW questionnaire.

Incorporating Mixed Reality for Knowledge Retention in Physiology, Anatomy, Pathology, and Pharmacology Interdisciplinary Education: A Randomized Controlled Trial.

Disease education is a fundamental component in health science and medicine curricula, as it prepares students for their progression into health profession careers. However, this requires an ability to integrate concepts across multiple disciplines. Technology-enhanced interventions may bridge this gap, and this study assessed the effectiveness of a textbook-style or a three-dimensional mixed reality (MR, a hybrid of augmented and virtual reality) HoloLens resource for student learning and knowledge retention using asthma as a model of disease. Sixty-seven first-year undergraduate health science and medical students were randomized into two groups to complete a lesson on the physiology, anatomy, pathology, and pharmacology of asthma, delivered through either a textbook-style (n = 34) or MR (n = 33) resource. Participants took part in the study in small groups and completed the intervention and surveys in separate areas of a large laboratory space. A pre-test prior to the lesson included multiple-choice questions, with the post-test having additional multiple-choice questions to assess learning. A follow-up test to assess retention was performed two weeks later. Pre- and post-test scores revealed increased learning across both the textbook (p = 0.001) and MR (p = 0.05) interventions, although higher test results were obtained by those using the textbook-style resource (p < 0.05). There was no difference between groups in knowledge retention scores. Although the textbook-style resource was more effective for increasing test results, participants perceived MR as more favorable, highlighting the experience as enjoyable and useful. This study presents MR as an option for integration in cases where educators wish to enhance student enjoyment of the learning experience. However, the results suggest that traditional text-based resources persist as a fundamental delivery mode within a modern curriculum.

Evaluation of an Infectious Diseases Elective for Early Clinical Medical Students on Their Internal Medicine Clerkship.

Background: Early medical subspecialty training is an emerging trend in medical education. These electives are still rare for Early Clinical Medical Students (ECMS). We describe the introduction of an Infectious Disease (ID) inpatient consult rotation elective for ECMS. Methods: In addition to seeing patients and rounding with the inpatient ID consult team, we created a supplemental curriculum to provide added support for ECMS that included a checklist of clinical skills learning objectives, self-directed, publicly available mini-lectures on ID topics, and an ID Coach who provided directed and personalized tutoring for students. We surveyed ECMS, ID fellows and attendings on service, and ID Coaches to evaluate the acceptability, feasibility, and effectiveness of this rotation and curriculum. Results: The majority of ECMS reported that the rotation was a useful educational experience and that the ID Coach was one of the most valuable aspects of the rotation. The majority of ID fellows and attendings reported that working with ECMS improved their job satisfaction and well-being. Conclusions: This multifaceted approach to early medical subspecialty training was valuable for ECMS, ID fellows, and faculty. Ongoing improvements in this curriculum will provide a useful tool for medical education.

A quasi-experimental study examining a nurse-led educational program to improve disease knowledge and self-care for patients with acute decompensated heart failure with reduced ejection fraction.

BACKGROUND: Nurse-led education can improve heart failure (HF) knowledge and self-care behaviors, and consequently lead to better patient outcomes. OBJECTIVES: To assess the effectiveness of "The Weak Heart" educational model in enhancing the level of disease knowledge and self-care behaviors among patients hospitalized with acute decompensated heart failure with reduced ejection fraction (HFrEF). MATERIAL AND METHODS: An evidence-based, standardized educational program was implemented for HF patients in Poland. We compared the initial level of HF knowledge - as rated using a self-developed questionnaire and self-care behaviors, evaluated according to the 9-item European Heart Failure Self-care Behavior Scale (9-EHFScBS) - to the results obtained at the 3-month follow-up period with a sample of patients (n = 231) hospitalized with acute decompensated HF (ADHF). RESULTS: The results showed a significant increase in total score of HF knowledge test depending on the time of measurement (χ2 = 356.526, p < 0.001) and in all individual questions on HF. The significant change of the 9-EHFScBS self-care questionnaire was also found in total score (Z = -7.317, p < 0.001), in all domains: autonomous-based adherence (Z = -5.870, p < 0.001); consulting behavior (Z = -7.238, p < 0.001); provider-based adherence (Z = -4.162; p < 0.001) and in relation to all individual statements except statement 7 ("I eat a low salt diet") and statement 9 ("I exercise regularly"). Within 3 months of hospital discharge, 84% (193 out of 231) of participants visited their primary care physician and 79% (183 out of 231) visited a cardiologist in accordance with their individual treatment plan. CONCLUSIONS: "The Weak Heart" educational model is effective in enhancing the level of HF knowledge and self-care behaviors among patients with decompensation of HFrEF.

Comparison of cardiac rehabilitation (exercise + education), exercise only, and usual care for patients with coronary artery disease: A non-randomized retrospective analysis.

Cardiac rehabilitation program is well-established but the Rehabilitation After Myocardial Infarction Trial (RAMIT) is reported that it does not affect mortality and morbidity of patients after myocardial infarction during follow-up period. The objectives of the study were to compare functional walking capacity, risk factor control, and morbidities in follow-up for cardiac rehabilitation (exercise + education), exercise only, and usual care among patients with coronary artery disease. A total of 492 male and female patients (age range: 45-73 years) with coronary artery disease after myocardial infarction or underwent percutaneous coronary intervention or coronary artery bypass grafting surgeries referred to cardiac rehabilitation were included in the study. Patients were participating in a cardiac rehabilitation program (exercise + education, CRP cohort, n = 125), exercise only (USC cohort, n = 182), or usual care (NCR cohort, n = 185). Data regarding incremental shuttle walk test, lipid profile, the Patient Health Questionnaire 9, and morbidities in follow-up of patients were retrospectively collected and analyzed. After completion of 1 year, cardiac rehabilitation program (p < 0.0001, q = 20.939) and exercise (p < 0.0001, q = 6.059) were successfully increased incremental shuttle walk test. After completion of 1 year, cardiac rehabilitation program reduced low-density lipoprotein (p = 0.007, q = 3.349) and depressive symptoms (p < 0.0001, q = 5.649). Morbidities were reported fewer in the patients of CRP cohort than those of USC (p = 0.003, q = 3.427) and NCR (p = 0.003, q = 4.822) cohorts after completion of 1 year of program. Cardiac rehabilitation program (exercise +education) improved functional walking capacity, controlled risk factors, and reduced morbidities of patients with coronary artery disease than exercise only and usual care (Level of evidence: III).

Utilization of CMS pre-ESRD Kidney Disease Education services and its associations with the home dialysis therapies.

BACKGROUND: Kidney Disease Education (KDE) has been shown to improve informed dialysis selection and home dialysis use, two long-held but underachieved goals of US nephrology community. In 2010, the Center for Medicare and Medicaid Services launched a policy of KDE reimbursements for all Medicare beneficiaries with advanced chronic kidney disease. However, the incorporation of KDE service in real-world practice and its association with the home dialysis utilization has not been examined. METHODS: Using the 2016 US Renal Data System linked to end-stage renal disease (ESRD) and pre-ESRD Medicare claim data, we identified all adult incident ESRD patients with active Medicare benefits at their first-ever dialysis during the study period (1 January 2010 to 31 December 2014). From these, we identified those who had at least one KDE service code before their dialysis initiation (KDE cohort) and compared them to a parsimoniously matched non-KDE control cohort in 1:4 proportions for age, gender, ESRD network, and the year of dialysis initiation. The primary outcome was home dialysis use at dialysis initiation, and secondary outcomes were home dialysis use at day 90 and anytime through the course of ESRD. RESULTS: Of the 369,968 qualifying incident ESRD Medicare beneficiaries with their first-ever dialysis during the study period, 3469 (0.9%) received KDE services before dialysis initiation. African American race, Hispanic ethnicity, and the presence of congestive heart failure and hypoalbuminemia were associated with significantly lower odds of receiving KDE services. Multivariate analyses showed that KDE recipients had twice the odds of initiating dialysis with home modalities (15.0% vs. 6.9%; adjusted odds ratio (aOR):95% confidence interval (CI) 2.0:1.7-2.4) and had significantly higher odds using home dialysis throughout the course of ESRD (home dialysis use at day 90 (17.6% vs. 9.9%, aOR:CI 1.7:1.4-1.9) and cumulatively (24.7% vs. 15.1%, aOR:CI 1.7:1.5-1.9)). CONCLUSIONS: Utilization of pre-ESRD KDE services is associated with significantly greater home dialysis utilization in the incident ESRD Medicare beneficiaries. The very low rates of utilization of these services suggest the need for focused systemic evaluations to identify and address the barriers and facilitators of this important patient-centered endeavor.

Understanding Patient Preferences and Unmet Needs in Non-alcoholic Steatohepatitis (NASH): Insights from a Qualitative Online Bulletin Board Study.

INTRODUCTION: The aim of this work was to understand how patients with non-alcoholic steatohepatitis (NASH) perceive their disease, unmet needs, and expectations regarding future treatment through online bulletin board (OBB) qualitative research. METHODS: OBB is an asynchronous online qualitative market research tool that provides an open forum for interactive discussion among participants. Patients with NASH were recruited via physician referral and completed a screener questionnaire to ensure their eligibility and willingness to participate. A trained moderator managed the discussion that allowed open answers and responses to other participants' posts. Patient responses were analyzed using a combination of different qualitative analytical tools. RESULTS: The OBB ran for 4 days and included 16 patients (n = 8, UK; n = 8, US) with NASH (fibrosis stages F1-F3) and comorbidities including diabetes/prediabetes (n = 9) and obesity (n = 12). The key insights were (1) patients with NASH have a poor understanding of the disease, its progression, and management-they feel a lack of adequate educational support from their physicians; (2) diagnosis of NASH is incidental in most cases, mainly because patients fail to spontaneously associate their signs or symptoms with their liver condition; (3) comorbidities (obesity and diabetes) are more concerning to patients than NASH; and (4) patients perceive that NASH impacts their social life and work performance in more advanced stages. CONCLUSIONS: This OBB provided valuable patient insights into NASH disease perception and management and revealed unmet need areas. In light of no approved therapies, these patient insights can inform early drug development strategies and stakeholder discussions on NASH. FUNDING: Novartis Pharma AG, Basel.

Top 20 POEMs of the Past 20 Years: A Survey of Practice-Changing Research for Family Physicians.

POEMs (patient-oriented evidence that matters) are studies that address a relevant clinical question, demonstrate improved patient-oriented outcomes, and have the potential to change practice. For 20 years the authors of this article have reviewed more than 100 English language clinical journals monthly to identify POEMs in the medical literature relevant to primary care practice. This article identifies the POEMs in each of the last 20 years that were highest ranked for having recommended a major and persistent change in practice that year. They include POEMs that recommend a novel, effective intervention, a second group that recommends abandoning an ineffective practice, and a third group that recommends abandoning a potentially harmful practice. The top POEMs of the past 20 years illustrate the breadth of practice change in primary care and the need for family physicians to have a systematic approach to keeping up with the medical literature, such as that in POEMs, especially because many of these important articles did not appear in the primary care literature.

A pilot survey of the U.S. medical waste industry to determine training needs for safely handling highly infectious waste.

BACKGROUND: The recent Ebola outbreak led to the development of Ebola virus disease (EVD) best practices in clinical settings. However, after the care of EVD patients, proper medical waste management and disposal was identified as a crucial component to containing the virus. Category A waste-contaminated with EVD and other highly infectious pathogens-is strictly regulated by governmental agencies, and led to only several facilities willing to accept the waste. METHODS: A pilot survey was administered to determine if U.S. medical waste facilities are prepared to handle or transport category A waste, and to determine waste workers' current extent of training to handle highly infectious waste. RESULTS: Sixty-eight percent of survey respondents indicated they had not determined if their facility would accept category A waste. Of those that had acquired a special permit, 67% had yet to modify their permit since the EVD outbreak. This pilot survey underscores gaps in the medical waste industry to handle and respond to category A waste. Furthermore, this study affirms reports a limited number of processing facilities are capable or willing to accept category A waste. CONCLUSIONS: Developing the proper management of infectious disease materials is essential to close the gaps identified so that states and governmental entities can act accordingly based on the regulations and guidance developed, and to ensure public safety.

A gap analysis of the United States death care sector to determine training and education needs pertaining to highly infectious disease mitigation and management.

PURPOSE: A United States industry-specific gap analysis survey of the death care sector-which comprises organizations and businesses affiliated with the funeral industry and the handling of human remains- was developed, the results analyzed, and training and education needs in relation to highly infectious disease mitigation and management were explored in an effort to identify where occupational health and safety can be enhanced in this worker population. METHODS: Collaborating national death care organizations distributed the 47-question electronic survey. N = 424 surveys were initiated and results recorded. The survey collected death care sector-specific information pertaining to the comfortability and willingness to handle highly infectious remains; perceptions of readiness, current policies and procedures in place to address highly infectious diseases; current highly infectious disease training levels, available resources, and personal protective equipment. RESULTS: One-third of respondents have been trained on how to manage highly infectious remains. There was a discrepancy between Supervisor/Management and Employee/Worker perceptions on employees' willingness and comfortability to manage potentially highly infectious remains. More than 40% of respondents did not know the correct routes of transmission for viral hemorrhagic fevers. CONCLUSIONS: Results suggest death care workers could benefit from increasing up-to-date industry-specific training and education on highly infectious disease risk mitigation and management. Professional death care sector organizations are positioned to disseminate information, training, and best practices.

Effect of an educational intervention on cardiovascular disease risk perception among women with preeclampsia.

OBJECTIVE: To promote knowledge and awareness about cardiovascular disease (CVD) among women with recent preeclampsia so that this population may develop more accurate perceptions of their personal CVD risk. DESIGN: An exploratory single group, pretest/posttest educational intervention study. SETTING: Telephone-based interviews. PARTICIPANTS: Sixty-four women with preeclampsia in the most recent pregnancy completed the study. The sample was predominately African American. METHODS: Knowledge about CVD and the study covariates (age, race, parity, income, marital status, education, and history of previous preeclampsia) were measured prior to CVD education. Levels of CVD risk perception were measured both before and after the CVD educational intervention. INTERVENTION: Structured CVD education by telephone. RESULTS: After CVD education, levels of CVD risk perception were significantly higher than at baseline. CONCLUSION: As an intervention, CVD education provided by telephone served as a practical and effective approach to contact postpartum women with recent preeclampsia and demonstrated effectiveness in increasing perception of CVD risk.

Enzymatic creatinine assays allow estimation of glomerular filtration rate in stages 1 and 2 chronic kidney disease using CKD-EPI equation.

The National Kidney Disease Education Program group demonstrated that MDRD equation is sensitive to creatinine measurement error, particularly at higher glomerular filtration rates. Thus, MDRD-based eGFR above 60 mL/min/1.73 m² should not be reported numerically. However, little is known about the impact of analytical error on CKD-EPI-based estimates. This study aimed at assessing the impact of analytical characteristics (bias and imprecision) of 12 enzymatic and 4 compensated Jaffe previously characterized creatinine assays on MDRD and CKD-EPI eGFR. In a simulation study, the impact of analytical error was assessed on a hospital population of 24084 patients. Ability using each assay to correctly classify patients according to chronic kidney disease (CKD) stages was evaluated. For eGFR between 60 and 90 mL/min/1.73 m², both equations were sensitive to analytical error. Compensated Jaffe assays displayed high bias in this range and led to poorer sensitivity/specificity for classification according to CKD stages than enzymatic assays. As compared to MDRD equation, CKD-EPI equation decreases impact of analytical error in creatinine measurement above 90 mL/min/1.73 m². Compensated Jaffe creatinine assays lead to important errors in eGFR and should be avoided. Accurate enzymatic assays allow estimation of eGFR until 90 mL/min/1.73 m² with MDRD and 120 mL/min/1.73 m² with CKD-EPI equation.

Ocular rosacea: a dermatologic perspective.

As many as 50% of patients given the diagnosis of cutaneous rosacea also have ocular rosacea. Conservative figures indicate that approximately 10 million patients are affected by ocular rosacea in the United States alone. Despite this prevalence, ocular symptoms of rosacea are often improperly diagnosed, particularly when they occur in the absence of skin involvement.
