Global consensus statement on simulation-based practice in healthcare.

Simulation plays a pivotal role in addressing universal healthcare challenges, reducing education inequities, and improving mortality, morbidity and patient experiences. It enhances healthcare processes and systems, contributing significantly to the development of a safety culture within organizations. It has proven to be cost-effective and successful in enhancing team performance, fostering workforce resilience and improving patient outcomes.Through an international collaborative effort, an iterative consultation process was conducted with 50 societies operating across 67 countries within six continents. This process revealed common healthcare challenges and simulation practices worldwide. The intended audience for this statement includes policymakers, healthcare organization leaders, health education institutions, and simulation practitioners. It aims to establish a consensus on the key priorities for the broad adoption of exemplary simulation practice that benefits patients and healthcare workforces globally.Key recommendations Advocating for the benefits that simulation provides to patients, staff and organizations is crucial, as well as promoting its adoption and integration into daily learning and practice throughout the healthcare spectrum. Low-cost, high-impact simulation methods should be leveraged to expand global accessibility and integrate into system improvement processes as well as undergraduate and postgraduate curricula. Support at institutional and governmental level is essential, necessitating a unified and concerted approach in terms of political, strategic and financial commitment.It is imperative that simulation is used appropriately, employing evidence-based quality assurance approaches that adhere to recognized standards of best practice. These standards include faculty development, evaluation, accrediting, credentialing, and certification.We must endeavor to provide equitable and sustainable access to high-quality, contextually relevant simulation-based learning opportunities, firmly upholding the principles of equity, diversity and inclusion. This should be complemented with a renewed emphasis on research and scholarship in this field.Call for action We urge policymakers and leaders to formally acknowledge and embrace the benefits of simulation in healthcare practice and education. This includes a commitment to sustained support and a mandate for the application of simulation within education, training, and clinical environments.We advocate for healthcare systems and education institutions to commit themselves to the goal of high-quality healthcare and improved patient outcomes. This commitment should encompass the promotion and resource support of simulation-based learning opportunities for individuals and interprofessional teams throughout all stages and levels of a caregiver's career, in alignment with best practice standards.We call upon simulation practitioners to champion healthcare simulation as an indispensable learning tool, adhere to best practice standards, maintain a commitment to lifelong learning, and persist in their fervent advocacy for patient safety.This statement, the result of an international collaborative effort, aims to establish a consensus on the key priorities for the broad adoption of exemplary simulation practice that benefits patients and healthcare workforces globally.

Informal settlements and the care of children 0-3 years of age: a qualitative study.

Background: There is a rapid increase in urbanization with a high percentage of people living in poverty in urban informal settlements. These families, including single parents, are requiring accessible and affordable childcare. In Mlolongo, an informal settlement in Machakos County in Nairobi metropolitan area, Kenya, childcare centres, referred to as 'babycares' are increasing in number. They are being provided by local community members without attention to standards or quality control. The study objective was to understand parents', caregivers' and community elders' experiences and perceptions in terms of the quality of babycares in Mlolongo to inform the design and implementation of improved early childcare services. Methods: Using a community-based participatory research philosophy, a qualitative study including focus group discussions with parents, community elders and babycare centre employees/owners (referred to as caregivers) was conducted in Mlolongo. Results: A total of 13 caregivers, 13 parents of children attending babycares, and eight community elders participated in the focus groups. Overall, community elders, parents and caregivers felt that the babycares were not providing an appropriate quality of childcare. The reported issues included lack of training and resources for caregivers, miscommunication between parents and caregivers on expectations and inappropriate child to caregiver ratio. Conclusion: The deficiencies identified by respondents indicate a need for improved quality of affordable childcare to support early child development in these settings. Efforts need to be invested in defining effective models of early childcare that can meet the expectations and needs of parents and caregivers and address the major challenges in childcare quality identified in this study.

Virtual care exercise interventions in multidisciplinary chronic pain clinics: a qualitative study of perspectives of adults living with chronic pain.

PURPOSE: Chronic pain affects 1 in 4 Canadians and is a leading contributor of disability. Although virtual care has become more prevalent, it is unclear how adults living with chronic pain perceive virtual delivery of exercise interventions within multidisciplinary chronic pain clinics (MCPC). This study explores the perspectives of adults living with chronic pain regarding their perceived barriers and facilitators and recommendations when implementing virtual care exercise interventions within MCPCs. METHODS: We conducted an interpretive description qualitative study based on semi-structured interviews with adults (age ≥18 years) living with chronic pain from a MCPC in Toronto, Canada, between March 1 and April 30, 2021. RESULTS: We completed fifteen (N = 15) interviews of adults living with chronic pain. We identified eight themes that addressed the study objectives: 1) virtual care supplements in-person care, 2) virtual care improves accessibility, 3) impact of technology on participation, 4) navigating the home environment, 5) impact of pain on participation, 6) impact of supervision and feedback, 7) the need for tailored care, and 8) the need for preparation and additional support. CONCLUSION: Our results reveal that adults living with chronic pain view virtual care exercise interventions positively however, the implementation of these interventions must be carefully considered within MCPCs. Specifically, virtual care was considered an excellent adjunct to in-person care but should not replace it completely.Implications for RehabilitationChronic pain is a leading contributor of disability.Exercise interventions are recommended component of comprehensive pain management.Virtual delivery of exercise interventions are becoming more prevalent.Adults living with chronic pain view virtual care exercise interventions positively as they can supplement in-person care and improve access to this type of care.

Medical education and population health-A framework in the design of a new undergraduate program.

Health sciences curricular planners are challenged to add new content to established education programs. There is increasing pressure for content in public health, health systems, global health, and planetary health. These important areas often compete for curricular time. What is needed is a convergence model that builds a common framework within which students can integrate areas and better align this knowledge to the individual client or patient who they have responsibility to support. A population health framework is proposed for health sciences education programs that supports a common conceptual understanding of population health. The framework links five thematic areas that have influence on health and wellbeing and a sixth element that defines the range of methodologies essential to understanding health and wellbeing, from the individual to the population. The five areas providing convergence are: (1) the biopsychosocial development of the individual, (2) the socioeconomic factors that influence health and wellbeing, (3) the physical natural and built environment including climate, (4) the continuum of public health and health care systems, and (5) the nation state and global relationships. Using this framework, students are encouraged to think and understand individual health and wellbeing in context to the population and to utilize the appropriate methodological tools to explore these relationships. Planning for a new undergraduate medicine program illustrates the curricular elements that will be used to support student learning with foundation knowledge applied and tracked throughout the program. The proposed framework has application across health sciences disciplines and serves to build a common understanding that supports cross professional communication and collaboration.

Five Influential Factors for Clinical Team Performance in Urgent, Emergency Care Contexts.

INTRODUCTION: In deployed contexts, military medical care is provided through the coordinated efforts of multiple interdisciplinary teams that work across and between a continuum of widely distributed role theaters. The forms these teams take, and functional demands, vary by roles of care, location, and mission requirements. Understanding the requirements for optimal performance of these teams to provide emergency, urgent, and trauma care for multiple patients simultaneously is critical. A team's collective ability to function is dependent on the clinical expertise (knowledge and skills), authority, experience, and affective management capabilities of the team members. Identifying the relative impacts of multiple performance factors on the accuracy of care provided by interdisciplinary clinical teams will inform targeted development requirements. MATERIALS AND METHODS: A regression study design determined the extent to which factors known to influence team performance impacted the effectiveness of small, six to eight people, interdisciplinary teams tasked with concurrently caring for multiple patients with urgent, emergency care needs. Linear regression analysis was used to distinguish which of the 11 identified predictors individually and collectively contributed to the clinical accuracy of team performance in simulated emergency care contexts. RESULTS: All data met the assumptions for regression analyses. Stepwise linear regression analysis of the 11 predictors on team performance yielded a model of five predictors accounting for 82.30% of the variance. The five predictors of team performance include (1) clinical skills, (2) team size, (3) authority profile, (4) clinical knowledge, and (5) familiarity with team members. The analysis of variance confirmed a significant linear relationship between team performance and the five predictors, F(5, 240) = 218.34, P < .001. CONCLUSIONS: The outcomes of this study demonstrate that the collective knowledge, skills, and abilities within an urgent, emergency care team must be developed to the extent that each team member is able to competently perform their role functions and that smaller teams benefit by being composed of clinical authorities who are familiar with each other. Ideally, smaller, forward-deployed military teams will be an expert team of individual experts, with the collective expertise and abilities required for their patients. This expertise and familiarity are advantageous for collective consideration of significant clinical details, potential alternatives for treatment, decision-making, and effective implementation of clinical skills during patient care. Identifying the most influential team performance factors narrows the focus of team development strategies to precisely what is needed for a team to optimally perform.

Child disability and family-centred care in East Africa: Perspectives from a workshop with stakeholders and health practitioners.

Background: Our understanding of child disability has undergone major changes over the last three decades transforming our approach to assessment and management. Globally there are significant gaps in the application of these 21st century models of care. There is recognition that economic, cultural, and social factors influence transitions in care and there is need to consider contextual factors. Objectives: A two-day workshop brought together key stakeholders to discuss current models of care and their application in the East African context. This article summarises workshop proceedings and identifies a broadly supported set of recommendations that serve to set a direction for health professionals, families, family-based disability organisations, communities and government. Method: Presentations followed by facilitated round-table sessions explored specific themes with participants reporting their responses communally. Future actions were agreed upon by relevant stakeholders. Results: Many barriers exist to care for children with disabilities in East Africa, including stigma and a lack of human and infrastructural resources. In addition, significant disparities exist with regard to access to medication and specialist care. The International Classification of Functioning framework needs to be translated to clinical practice within East Africa, with due recognition of the importance of family-centred care and emphasis on the life course theory for disability care. Family-centred care, educational initiatives, advocacy on the part of stakeholders and involvement of government policymakers are important avenues to improve outcomes. Conclusion: Further education and data are needed to inform family-centred care and multidisciplinary team implementation across East African care contexts for children with disabilities.

Flea and tick treatment satisfaction, preference, and adherence reported by cat owners in the US, UK, or France who treated their cats with transdermal fluralaner.

Background: Fluralaner (Bravecto®) is an isoxazoline class compound that is the only topically applied systemic ectoparasiticide approved for dosing at up to 12-week intervals for flea and tick control in cats. Aim: To describe veterinarian recommendations for ectoparasiticide medications used in the UK and France along with veterinary recommendations previously reported from the US, as well as to assess cat owners' experience with a commercial transdermal spot-on fluralaner formulation administered to cats in the US and similarly describe the experiences of cat owners from the UK or France who administered fluralaner for feline flea and tick prevention. Methods: Clients of participating veterinary practices in the US, UK, or France who were visiting the clinic for a routine wellness visit, were currently treating their cat with fluralaner (Bravecto®), and had purchased at least two doses were asked to complete a short two-page survey about their experience with flea and tick medications including fluralaner and other products they may have been administered. Results: Owners in the US (451 cats), UK (512 cats), and France (520 cats) completed surveys. Most cat owners (66%-75%) had previously administered other flea and tick products. More than 94% of cat owners surveyed in each country were satisfied or very satisfied with fluralaner. The most frequently reported benefit of using fluralaner was the 12-week dosing interval, selected by 76% of respondents in the US, 82% in the UK, and 70% in France. 79%-88% of cat owners (depending on the country) thought that dosing with extended duration fluralaner was more convenient than dosing with monthly flea and tick products and 86%-89% of cat owners that had used other flea and tick products preferred fluralaner over the other flea and tick products. Conclusion: Veterinarians in the US, UK, and France recommended 12 months of flea protection and 9-11 months of tick protection per year, even though, in this study, cat owners usually purchased 1-3 months of protection per year. A longer flea and tick dosing interval, as seen with fluralaner, correlates with higher user satisfaction and preference among cat owners. Owners identified the 12-week dosing interval and single dose efficacy as the top reasons for selecting the fluralaner product for their cat. In all three countries, most cat owners indicated that they were more likely to deliver doses of extended duration fluralaner on time, compared to flea and tick products dosed monthly.

Safety and Efficacy of Natalizumab as Adjunctive Therapy for People With Drug-Resistant Epilepsy: A Phase 2 Study.

BACKGROUND AND OBJECTIVES: To explore efficacy/safety of natalizumab, a humanized monoclonal anti-α4-integrin antibody, as adjunctive therapy in adults with drug-resistant focal epilepsy. METHODS: Participants with ≥6 seizures during the 6-week baseline period were randomized 1:1 to receive natalizumab 300 mg IV or placebo every 4 weeks for 24 weeks. Primary efficacy outcome was change from baseline in log-transformed seizure frequency, with a predefined threshold for therapeutic success of 31% relative reduction in seizure frequency over the placebo group. Countable seizure types were focal aware with motor signs, focal impaired awareness, and focal to bilateral tonic-clonic. Secondary efficacy endpoints/safety were also assessed. RESULTS: Of 32 and 34 participants dosed in the natalizumab 300 mg and placebo groups, 30 (94%) and 31 (91%) completed the placebo-controlled treatment period, respectively (one participant was randomized to receive natalizumab but not dosed due to IV complications). Estimated relative change in seizure frequency of natalizumab over placebo was -14.4% (95% confidence interval [CI] -46.1%-36.1%; p = 0.51). The proportion of participants with ≥50% reduction from baseline in seizure frequency was 31.3% for natalizumab and 17.6% for placebo (odds ratio 2.09, 95% CI 0.64-6.85; p = 0.22). Adverse events were reported in 24 (75%) and 22 (65%) participants receiving natalizumab vs placebo. DISCUSSION: Although the threshold to demonstrate efficacy was not met, there were no unexpected safety findings and further exploration of possible anti-inflammatory therapies for drug-resistant epilepsy is warranted. TRIAL REGISTRATION INFORMATION: The ClinicalTrials.gov registration number is NCT03283371. CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that IV natalizumab every 4 weeks, compared to placebo, did not significantly change seizure frequency in adults with drug-resistant epilepsy. The study lacked the precision to exclude an important effect of natalizumab.

Global Gaps in Training Opportunities for Pediatricians and Pediatric Subspecialists.

OBJECTIVE: A comprehensive, well-trained pediatric workforce is needed to ensure high-quality child health interventions around the globe. Further understanding of pediatric workforce training capacity would assist planning at the global and country level. The purpose of this study was to better understand the availability and process of training programs for pediatricians and pediatric subspecialists worldwide, as well as in-country presence of subspecialists. METHODS: A survey was developed and distributed by e-mail to national pediatric leaders across the globe. The survey asked about the number of pediatric training programs, duration and logistics of training, and whether practicing pediatric subspecialists and subspecialty training programs were available in their country. RESULTS: We received responses from 121 of the 166 countries contacted (73%). Of these, 108 countries reported the presence of one or more general pediatric postgraduate training programs, ranging from 1 to 500 programs per country. The number of training programs did not vary significantly by gross domestic product but did vary by region, with the fewest in Africa (P < .001). Most countries identified national guidelines for training (82% of countries) and accreditation (84% of countries). Availability of pediatric subspecialists varied significantly by income and region, from no subspecialties available in 4 countries to all 26 queried subspecialties available in 17 countries. Neonatology was most common, available in 88% of countries. Subspecialty training programs were less available overall, significantly correlating with country income. CONCLUSION: Education for general pediatrics and pediatric subspecialties is quite limited in many of the countries surveyed, particularly in Africa. The creation of additional educational capacity is a critical issue challenging the adequate provision of pediatrics and pediatric subspecialty services.

Local Health Department Interest in Implementation of a Jail-Based Human Papillomavirus Vaccination Program in Kansas, Iowa, Missouri, and Nebraska.

CONTEXT: Local health departments (LHDs) play a vital role in community vaccination programs for human papillomavirus (HPV) infection, but little research has been done to assess LHD interest in cross-sectoral partnerships to vaccinate high-risk groups, specifically incarcerated persons. OBJECTIVE: To describe factors associated with interest in a novel implementation strategy linking LHDs with jails in 4 Midwestern states to deliver HPV vaccine. DESIGN: Survey based on the Consolidated Framework for Implementation Research (CFIR) model given to LHD administrators. A modified Poisson relative risk regression was used to assess the relationship between independent variables and LHD interest in implementation of a jail-based HPV vaccination program. SETTING: LHDs in Kansas, Missouri, Iowa, and Nebraska. PARTICIPANTS: From September 2017 to April 2018, two-thirds (237/344) of invited LHD administrators from the 4 states responded to the survey. MAIN OUTCOME MEASURE: LHD interest in implementation of a jail-based HPV vaccination program. RESULTS: Forty-five percent of LHDs were interested in learning more about implementing a jail-based HPV vaccination program, and 2% already offered or had plans to offer HPV vaccine in their jails. Barriers to implementation were cost (66%), inmates' short incarcerations (47%), and availability of medical staffing (43%). LHD characteristics associated with interest in implementation of a jail-based HPV vaccination program included "inner setting" CFIR variables, which capture the structural and cultural context for program implementation: 7 or more employees (odds ratio [OR] = 2.22; 95% confidence interval [CI], 1.24-3.95), perception of importance to provide HPV vaccine in jails (OR = 3.70; 95% CI, 2.00-6.84), and already providing any vaccines in jails (OR = 2.62; 95% CI, 1.18-5.80). CONCLUSIONS: Nearly half of LHDs in the region expressed interest in partnering with local entities to meet HPV vaccination needs of high-risk groups. Research on cross-sectoral partnerships and what these collaborations look like in practice is needed for public health impact.

Displacement Talbot lithography for nano-engineering of III-nitride materials.

Nano-engineering III-nitride semiconductors offers a route to further control the optoelectronic properties, enabling novel functionalities and applications. Although a variety of lithography techniques are currently employed to nano-engineer these materials, the scalability and cost of the fabrication process can be an obstacle for large-scale manufacturing. In this paper, we report on the use of a fast, robust and flexible emerging patterning technique called Displacement Talbot lithography (DTL), to successfully nano-engineer III-nitride materials. DTL, along with its novel and unique combination with a lateral planar displacement (D2TL), allow the fabrication of a variety of periodic nanopatterns with a broad range of filling factors such as nanoholes, nanodots, nanorings and nanolines; all these features being achievable from one single mask. To illustrate the enormous possibilities opened by DTL/D2TL, dielectric and metal masks with a number of nanopatterns have been generated, allowing for the selective area growth of InGaN/GaN core-shell nanorods, the top-down plasma etching of III-nitride nanostructures, the top-down sublimation of GaN nanostructures, the hybrid top-down/bottom-up growth of AlN nanorods and GaN nanotubes, and the fabrication of nanopatterned sapphire substrates for AlN growth. Compared with their planar counterparts, these 3D nanostructures enable the reduction or filtering of structural defects and/or the enhancement of the light extraction, therefore improving the efficiency of the final device. These results, achieved on a wafer scale via DTL and upscalable to larger surfaces, have the potential to unlock the manufacturing of nano-engineered III-nitride materials.

Where are the paediatricians? An international survey to understand the global paediatric workforce.

OBJECTIVE: Our primary objective was to examine the global paediatric workforce and to better understand geographic differences in the number of paediatricians globally. Secondary objectives were to describe paediatric workforce expectations, who provides children with preventative care and when children transition out of paediatric care. DESIGN: Survey of identified paediatric leaders in each country. SETTING: Paediatric association leaders worldwide. MAIN OUTCOME MEASURES: Paediatrician numbers, provision of primary care for children, age of transition to adult care. RESULTS: Responses were obtained from 121 countries (73% of countries approached). The number of paediatricians per 100 000 children ranged from a median of 0.5 (IQR 0.3-1.4) in low-income countries to 72 (IQR 4-118) in high-income countries. Africa and South-East Asia reported the lowest paediatrician density (median of 0.8 paediatricians per 100 000 children, IQR 0.4-2.6 and median of 4, IQR 3-9, respectively) and fewest paediatricians entering the workforce. 82% of countries reported transition to adult care by age 18% and 39% by age 15. Most countries (91%) but only 64% of low-income countries reported provision of paediatric preventative care (p<0.001, Cochran-Armitage trend test). Systems of primary care provision varied widely. A majority of countries (63%) anticipated increases in their paediatric workforce in the next decade. CONCLUSIONS: Paediatrician density mirrors known inequities in health provider distribution. Fewer paediatricians are entering the workforce in areas with already low paediatrician density, which may exacerbate disparities in child health outcomes. In some regions, children transition to adult care during adolescence, with implications for healthcare training and delivery. Paediatrician roles are heterogeneous worldwide, and country-specific strategies should be used to address inequity in child health provision.

Multiscale Nature of Thixotropy and Rheological Hysteresis in Attractive Colloidal Suspensions under Shear.

Colloids with short range attractions self-assemble into sample-spanning structures, whose dynamic nature results in a thermokinematic memory of the deformation history, also referred to as "thixotropy." Here, we study the origins of the thixotropic effect in these time- and rate-dependent materials by investigating hysteresis across different length scales: from particle-level local measurements of coordination number (microscale), to the appearance of density and velocity fluctuations (mesoscale), and up to the shear stress response to an imposed deformation (macroscale). The characteristic time constants at each scale become progressively shorter, and hysteretic effects become more significant as we increase the strength of the interparticle attraction. There are also strong correlations between the thixotropic effects we observe at each scale.

Platinum Nanoparticle Inclusion into a Carbonized Polymer of Intrinsic Microporosity: Electrochemical Characteristics of a Catalyst for Electroless Hydrogen Peroxide Production.

The one-step vacuum carbonization synthesis of a platinum nano-catalyst embedded in a microporous heterocarbon (Pt@cPIM) is demonstrated. A nitrogen-rich polymer of an intrinsic microporosity (PIM) precursor is impregnated with PtCl62- to give (after vacuum carbonization at 700 °C) a nitrogen-containing heterocarbon with embedded Pt nanoparticles of typically 1⁻4 nm diameter (with some particles up to 20 nm diameter). The Brunauer-Emmett-Teller (BET) surface area of this hybrid material is 518 m² g-1 (with a cumulative pore volume of 1.1 cm³ g-1) consistent with the surface area of the corresponding platinum-free heterocarbon. In electrochemical experiments, the heterocarbon-embedded nano-platinum is observed as reactive towards hydrogen oxidation, but essentially non-reactive towards bigger molecules during methanol oxidation or during oxygen reduction. Therefore, oxygen reduction under electrochemical conditions is suggested to occur mainly via a 2-electron pathway on the outer carbon shell to give H2O2. Kinetic selectivity is confirmed in exploratory catalysis experiments in the presence of H2 gas (which is oxidized on Pt) and O2 gas (which is reduced on the heterocarbon surface) to result in the direct formation of H2O2.

In-home assessment of either topical fluralaner or topical selamectin for flea control in naturally infested cats in West Central Florida, USA.

BACKGROUND: An investigation was conducted in West Central Florida, USA to evaluate the efficacy of either topically applied fluralaner or topically applied selamectin to control flea infestations, minimize dermatologic lesions and reduce pruritus in naturally flea infested cats over a 12-week period. When dogs were present in the households, they were treated with either oral fluralaner (if household cats were treated with topical fluralaner) or oral sarolaner (if household cats were treated with topical selamectin). METHODS: Thirty-one cats in 20 homes were treated once with fluralaner topical solution on day 0 and 18 dogs in these homes were administered a single fluralaner chewable. Twenty-nine cats in 18 homes were treated once monthly with a selamectin topical solution for 3 treatments and 13 dogs in these same homes were treated once monthly for 3 treatments with a sarolaner chewable. Fleas on cats were counted by flea combing, fleas on dogs were estimated using visual area counts and fleas in the indoor premises were assessed using intermittent-light flea traps. Blinded-assessments of feline dermatologic lesions were conducted monthly and pruritus severity was evaluated by pet owners. RESULTS: A single topical application of fluralaner reduced flea populations on cats by 96.6% within 7 days and by 100% at 12 weeks post-treatment. This efficacy was significantly greater than selamectin treatment where single topical application reduced flea populations on cats by 79.4% within 7 days of initial treatment and 3 consecutive monthly treatments reduced flea populations by 91.3% at the end of 12 weeks. At the end of the 12-week study, all fluralaner-treated cats were flea-free and this was significantly greater than the 38.5% of selamectin treated cats that were flea-free. At the end of the study, fleas were completely eradicated (from cats, dogs and homes) in 95.0% of fluralaner treatment group homes, significantly greater than the 31.3% of selamectin/sarolaner treatment group homes with complete flea eradication. Owner reported cat pruritus was reduced similarly in both treatment groups. Significant improvements in dermatologic lesion scores were achieved by day 30 in fluralaner treated cats and by day 60 in selamectin treated cats. CONCLUSIONS: An in-home investigation in subtropical Florida found that 1 application of topical fluralaner eliminated flea infestations on cats and in homes significantly more effectively than 3 consecutive monthly doses of selamectin.

Toward Live Virtual Constructive Simulations in Healthcare Learning.

STATEMENT: This article explores the combination of live, virtual, and constructive (LVC) simulations in healthcare. Live, virtual, and constructive simulations have long existed in the military, but their consideration (and deployment) in medical and healthcare domains is relatively new. We conducted a review on LVC- its current application in the military domain -and highlight an approach, challenges, and present suggestions for its implementation in healthcare learning. Furthermore, based on the state of the art in simulation in healthcare, we suggest that a combination of two simulation types (LV, VC, LC) at the time may be a simpler approach to the community at large.
