RESUMO

INTRODUCTION: The medical laboratory science (MLS) profession is an integral part of the healthcare team, providing diagnostic laboratory results used to determine directives in the treatment and management of disease processes. There is a scarcity of literature describing other healthcare professionals' perceptions of medical laboratory scientists. Research also suggests MLS professionals feel unrecognized for contributions to patient care. PURPOSE: A pilot study to describe intensive care unit (ICU) nurses' perceptions of medical laboratory scientists and their role in healthcare. METHODS: Five ICU nurses were interviewed using open-ended questions. Data were analyzed using phenomenological research inquiry to develop themes. RESULTS: Four themes were identified: professional practice, visibility, professional entry, and interprofessional learning. DISCUSSION: While participants were aware of the medical laboratory, they were unaware of the scope of practice, educational requirements, and professional credentials of medical laboratory scientists. Findings also showed misconceptions of the MLS scope of practice that overlaps with phlebotomists and medical laboratory technicians (MLTs). CONCLUSION: This study found that the intensive care nurse participants demonstrated an overall positive perception of medical laboratory scientists but a low level of knowledge of the MLS profession and expertise. Implications for interdisciplinary education to create a more comprehensive healthcare delivery team were presented.

RESUMO

The COVID pandemic has put a spotlight on laboratory medicine, showcasing how vital diagnostic testing is for society and the health care system. It has also brought to light and accelerated the critical shortage of trained and experienced laboratory personnel that has been felt for decades. The need for laboratory professionals is expected to grow by 11% between 2020 and 2030, a higher rate of growth than the overall average for all other health care occupations. Here, the background to this workforce shortage is reviewed. Some proposed actions to help address the issue are put forth, including increasing awareness of the medical laboratory science profession along with bolstering training opportunities and awareness of alternate routes to obtaining certification as a medical laboratory scientist. In addition, recent survey data specifically related to the employee shortages in microbiology are presented which demonstrate that 80% of microbiology laboratories have vacant positions and that filling these positions is challenging for a number of reasons, including a lack of qualified applicants.

RESUMO

Historically, Youden plots are made of a scatter plot of the results of two EQA samples with an elliptical confidence area around them. Because Youden plots compare individual laboratory results with respect to other laboratories, they intrinsically evaluate with state of the art. In the field of medical laboratory science, analytical performance specifications have been proposed and various EQA providers show these limits on Youden plots by horizontal and vertical lines near the limits of total error. This study shows the weaknesses of these limits of total error and proposes a new approach for drawing acceptance areas on Youden plots. The classical Youden plot is extended with two acceptance areas: A first acceptance area evaluates the reported results with respect to maximum allowed variability, a second acceptance area evaluates the results with respect to maximum allowed variability and bias. The ellipses are calculated using quantiles of the Chi-square and noncentral Chi-square distribution. Results show that the new approach allows evaluating results from individual laboratories and from measurement procedures by comparing the position and overlap of the confidence area and the acceptance areas. It is demonstrated that his approach controls the type I error better than the rectangular limits.

RESUMO

OBJECTIVES: Choosing Wisely Canada (CWC) publishes practices that may contribute to medical overuse and patient harm. Many practices concern laboratory testing, but the recommendations are often written for the test-ordering professionals. Our objective was to develop a list for CWC reflecting the scope of practice of nonpathologist medical laboratory professionals (MLPs). METHODS: We used a national survey, a convention session, and a panel of MLPs from across Canada to generate content for the CWC list. We used a modified Delphi process to identify the most important items and scoping reviews to gather evidence supporting each item. RESULTS: We identified 95 potential CWC list items. After 2 Delphi rounds, there was little movement in the top items. Scoping reviews revealed varying degrees of evidentiary support, which influenced the composition of the final list of 7 CWC items submitted. Three of the final recommendations address ways MLPs preserve the status quo with respect to overutilization of laboratory tests by other health care professionals. The remaining recommendations prompt MLPs to exert clinical judgment in specific scenarios, particularly where they can impact blood collection volumes. CONCLUSIONS: This work brings a more nuanced and comprehensive understanding of the relationships among MLPs, patient safety, and resource waste.

RESUMO

OBJECTIVE: In medical laboratory science, there is a need to enhance the clinical learning curriculum beyond laboratory skill and diagnostic interpretation competency. Incorporating simulation presents an opportunity to train and produce medical laboratory scientists with the skills to communicate and work effectively in an interprofessional healthcare team. METHODS: A scoping review was performed to (i) understand the landscape of research literature on medical laboratory science and simulation and (ii) provide a path for future research directions. The International Nursing Association for Clinical Simulation and Learning Standards of Best Practice: Simulation were used as a guiding framework for literature that described simulation activities. RESULTS: Out of 439 articles from multiple databases, 32 were eligible for inclusion into this review. Of the 14 articles that described a simulation activity, only 3 described or partially described each component of the best practice criteria for simulation. Articles that did not describe the design and implementation of simulation (n = 18) consisted of 7 opinion-based papers, 4 narrative reviews, 5 case reports, and 2 empirical papers. CONCLUSION: Despite increases in medical laboratory science with simulation, there is a need for more detailed empirical studies, more studies with an interprofessional context, and more methodological rigor.

RESUMO

BACKGROUND: A bibliometric analysis of the Annals of Laboratory Medicine (ALM) was performed to understand its position in the medical laboratory technology category and to suggest a developmental strategy. METHODS: Journal metrics, including the number of articles by publication type, country of authors, total citations, 2-year impact factor, country of cited authors, journals citing ALM, and Hirsch-index, were obtained from the Journal Citation Report and Web of Science Core Collection. Target data included ALM content in the Web of Science from January 1, 2012, to October 5, 2021. Bibliometric analysis was performed using Biblioshiny. RESULTS: The impact factor increased from 1.481 in 2013 to 3.464 in 2020. Authors belonging to the USA, China, and Korea cited ALM articles the most. Plos One, Scientific Reports, and Frontiers in Microbiology most frequently cited ALM, besides ALM itself. The Hirsch-index was 34. The co-occurrence network of Keyword Plus indicated four clusters: diagnosis, identification, prevalence, and risk. The conceptual structure map of Keyword Plus based on multiple correspondence analysis showed two clusters: bacterial susceptibility at the bench and clinical courses. The co-citation network showed that ALM was in the cluster of the New England Journal of Medicine, The Lancet, JAMA, and the Annals of Internal Medicine. The collaboration network showed that Korean authors collaborated mainly with authors from the USA, Germany, and Italy. CONCLUSIONS: The journal's promotion to an international top-tier journal has been successful. "Principles of transparency and best practice in scholarly publishing" and a preprint policy are yet to be added.

RESUMO

The purpose of this research study was to explore: (1) the factors that influence career choice among medical laboratory science (MLS) students and recent graduates, and (2) the impact the COVID-19 pandemic has had on these factors. A cross-sectional study was conducted using a modified version of the Health Care Choice instrument to include questions regarding COVID-19. Seventy-two students enrolled in undergraduate and graduate-level MLS programs at a single mid-Atlantic university completed the survey. Statistical analyses were performed to identify relationships between factors that influence career choice and particular demographic factors, as well as the impact of COVID-19 on these factors. Personal interests and nature of the work were the influencing factors rated highest, followed by job prospects. Prior healthcare exposure, self-efficacy, and social influences were rated lower. There were few significant differences based on demographic factors. Participants reported being personally impacted by the COVID-19 pandemic, but for most it did not change their career choice. Recruitment strategies should focus on the impact that medical laboratory sciences professionals have on people's lives and the highly skilled, hands-on nature of the work, particularly during and after the COVID-19 pandemic.

RESUMO

The existing paired t-test under classical statistics cannot be applied when the data is obtained from the complex process, having interval, uncertainty, indeterminacy, and incompleteness. In this paper, the modification of the paired t-test under neutrosophic statistics is proposed. The testing criterion of the proposed paired t-test is given. The application of the proposed paired t-test is given using the interval quality control of clinical laboratory data. From the analysis, it can be seen than the proposed test is quite effective and informative to apply for testing the measurement tools in the clinical laboratory.

RESUMO

Artificial Intelligence (AI) and machine learning (ML) have now spawned a new field within health care and health science research. These new predictive analytics tools are starting to change various facets of our clinical care domains including the practice of laboratory medicine. Many of these ML tools and studies are also starting to populate our literature landscape as we know it but unfamiliarity of the average reader to the basic knowledge and critical concepts within AI/ML is now demanding a need to better prepare our audience to such relatively unfamiliar concepts. A fundamental knowledge of such platforms will inevitably enhance cross-disciplinary literacy and ultimately lead to enhanced integration and understanding of such tools within our discipline. In this review, we provide a general outline of AI/ML along with an overview of the fundamental concepts of ML categories, specifically supervised, unsupervised, and reinforcement learning. Additionally, since the vast majority of our current approaches within ML in laboratory medicine and health care involve supervised algorithms, we will predominantly concentrate on such platforms. Finally, the need for making such tools more accessible to the average investigator is becoming a major driving force for the need of automation within these ML platforms. This has now given rise to the automated ML (Auto-ML) world which will undoubtedly help shape the future of ML within health care. Hence, an overview of Auto-ML is also covered within this manuscript which will hopefully enrich the reader's understanding, appreciation, and the need for embracing such tools.

RESUMO

Snakebite envenomation is a public health problem of high impact, particularly for the developing world. Antivenom, which contains whole or protease-digested immunoglobulin G, purified from the plasma of hyper-immunized animals (mainly horses), is the mainstay for the treatment of snakebite envenomation. The success of antivenom therapy depends upon its ability to abrogate or reduce the local and systemic toxicity of envenomation. In addition, antivenom administration must be safe for the patients. Therefore, antivenom manufacturers must ensure that these products are effective and safe in the treatment of envenomations. Antivenom efficacy and safety are determined by the physicochemical characteristics of formulations, purity of the immunoglobulin fragments and antibodies, presence of protein aggregates, endotoxin burden, preservative load, and batch to batch variation, as well as on the ability to neutralize the most important toxins of the venoms against which the antivenom is designed. In this context, recent studies have shown that laboratory-based simple analytical techniques, for example, size exclusion chromatography, sodium dodecyl sulphate polyacrylamide gel electrophoresis, mass spectrometry, immunological profiling including immuno-turbidimetry and enzyme-linked immunosorbent assays, Western blotting, immune-chromatographic technique coupled to mass spectrometry analysis, reverse-phase high performance liquid chromatography, spectrofluorometric analysis, in vitro neutralization of venom enzymatic activities, and other methodologies, can be applied for the assessment of antivenom quality, safety, stability, and efficacy. This article reviews the usefulness of different analytical techniques for the quality assessment of commercial antivenoms. It is suggested that these tests should be applied for screening the quality of commercial antivenoms before their preclinical and clinical assessment.

RESUMO

BACKGROUND: The concern over the high level of stress experienced by students of the caring professions has led to increased attention being paid to the promotion of their resilience. Most earlier studies have focused on the resilience of medical and nursing students. There has been little exploration of the resilience and associated factors of students of other health-care disciplines. The aim of this study was to gather data from students of pre-registration health-care disciplines to identify the factors that influence their resilience. METHOD: Valid questionnaires were used to assess respondents' resilience, self-efficacy, mindfulness, coping and trait positive and negative affect. The data were analyzed using descriptive statistics and univariate and general linear regression. RESULTS: A total of 1320 university students from nursing, medical laboratory science, radiography and optometry were recruited. The results showed that the subjects' resilience scores were lower than those of students in Western countries. We found self-efficacy and denial to be the common predictors for students of all disciplines. CONCLUSION: The resilience of students in the four disciplines was predicted by a combination of predictors. Faculties of universities and clinical mentors should collaborate in building resilience in their health-care students and support them to grow both personally and professionally during their careers.

RESUMO

OBJECTIVE: Laboratory professionals must communicate effectively on an interprofessional team. It is the responsibility of Medical Laboratory Science (MLS) programs to teach communication. The structured communication tool Situation, Background, Assessment, and Recommendation (SBAR) is one way to promote effective communication. METHODS: Students participated in a case-based simulation activity on the importance of teamwork/communication and the use of SBAR and completed a pre/post survey on communicating interprofessionally. RESULTS: Students reported increased confidence and competence with interprofessional communication after the activity with 4 of 5 questions demonstrating a statistically significant increase in scores post SBAR instruction. CONCLUSIONS: Our study demonstrates that SBAR is a suitable communication tool that can be used to increase our MLS students' confidence and competency in interprofessional communication. Educators should use this communication tool to empower MLS students to be effective members of the healthcare team.

RESUMO

INTRODUCTION: To interpret test results correctly, understanding of the variations that affect test results is essential. The aim of this study is: 1) to evaluate the clinicians' knowledge and opinion concerning biological variation (BV), and 2) to investigate if clinicians use BV in the interpretation of test results. MATERIALS AND METHODS: This study uses a questionnaire comprising open-ended and close-ended questions. Questions were selected from the real-life numerical examples of interpretation of test results, the knowledge about main sources of variations in laboratories and the opinion of clinicians on BV. A total of 399 clinicians were interviewed, and the answers were evaluated using a scoring system ranked from A (clinician has the highest level of knowledge and the ability of using BV data) to D (clinician has no knowledge about variations in laboratory). The results were presented as number (N) and percentage (%). RESULTS: Altogether, 60.4% of clinicians have knowledge of pre-analytical and analytical variations; but only 3.5% of them have knowledge related to BV. The number of clinicians using BV data or reference change value (RCV) to interpret measurements results was zero, while 79.4% of clinicians accepted that the difference between two measurements results located within the reference interval may be significant. CONCLUSIONS: Clinicians do not use BV data or tools derived from BV such as RCV to interpret test results. It is recommended that BV should be included in the medical school curriculum, and clinicians should be encouraged to use BV data for safe and valid interpretation of test results.

RESUMO

The COVID-19 pandemic has taken a major toll on the economy and funding for public education. For that reason, the pandemic has a worrisome effect on the sustainability of university/college based Medical Laboratory Sciences MLS training programs. Stakeholders of university-based MLS programs include university administrators, students, clinical affiliates and faculty. Each group has specific goals and challenges that affect the sustainability of the program. This report details strategies that can be used to satisfy the goals specific to key stakeholders that lead to sustainability. These strategies apply in pandemic times and in the back-to-normal future.

RESUMO

Public health laboratories have played a central role in the US response to COVID-19. Since the earliest days, myriad issues have impeded the laboratory community's ability to keep pace with the overwhelming demand for effective tests. In this article, the Association of Public Health Laboratories and a subset of its members examine the response to date and evaluate lessons learned from 4 main categories: testing surges, supplies, staffing, and regulations and policy. Within these categories, the authors offer recommendations intended both to improve the ongoing COVID-19 response and to strengthen planning for future outbreaks.

RESUMO

Formal medical and public health microbiology (MPHM) fellowship programs play a key role in preparing future clinical microbiology laboratory directors for their leadership and management responsibilities. Given the continually evolving MPHM field, fellowships must remain adaptable to changes in the field, providing trainees with the opportunity to engage with newly emerging diagnostic modalities, while continuing to emphasize the "bread and butter" techniques of clinical microbiology. This article discusses the key components of a fellowship program and provides recommendations for incorporating educational best practices.
