Revisiting the effects of state anesthesia policy interventions: A comprehensive look at certified registered nurse anesthetist service provision in U.S. hospitals from 2010 to 2021.

AIMS: Rural hospitals in the United States often rely on nonphysician providers such as advanced practice nurses to care for their patients. One important role that is served by advanced practice nurses is that of anesthesia provider (certified registered nurse anesthetist or CRNA). In 2001, Centers for Medicare & Medicaid Services (CMS) passed an opt-out law affording state governors the right to loosen physician supervision requirements on CRNAs in their respective states, thus potentially improving access in targeted areas. Since then, 24 states have adopted these opt-out provisions. We aim to understand the extent to which the CMS opt-out law has resulted in increased CRNA service provision in hospitals, especially in rural areas. DESIGN: The study used a longitudinal design. We compiled 2010-2021 American Hospital Association data, which includes 4,464 unique U.S. hospitals observed an average of 8 times annually (35,863 total hospital-year observations). METHODS: We model CRNA services provision at the hospital level using longitudinal mixed effects generalized linear models that incorporate state, county, and hospital control variables. RESULTS: Using descriptive statistics and mixed effects generalized linear models, we discovered that adopting opt-out provisions does not universally result in increased CRNA service provision in U.S. hospitals. Notably, opt-out provisions do not improve access in rural counties. However, in supplemental analysis, we discover some of the conditions under which the likelihood of CRNA service provision is influenced. CONCLUSIONS: Hospitals often utilize CRNAs to staff their hospitals. However, many hospitals use both CRNAs and physician anesthesiologists; this can be a potential source of contention and confusion, given the lack of uniformity in the scope of practice policies. We offer some suggestions with regard to the effects of state interventions into the field, and how they might impact this dispute. Lastly, policymakers should consider additional measures to address rural access limitations, as the opt-out policy does not seem to be working as intended.

A Mixed-Methods Exploration of Competencies and Professional Development Needs Among Chief Certified Registered Nurse Anesthetists.

This project sought to explore the experiences, self-perceived preparation, professional development needs, and preferred learning methods of certified registered nurse anesthetists (CRNAs) in a management role. A sample of 10 current chief CRNAs responded to a demographics survey and participated in one-on-one interviews using a 14-question, semi-structured interview framework modified from a previous study. Interview responses were deidentified and qualitatively analyzed for common themes by two content experts and one qualitative analysis expert. Results suggest that CRNAs entering the management field feel somewhat unprepared to perform the administrative tasks associated with their role. Qualitative analysis of interview responses elicited multiple key themes including interpersonal communication and handling crucial conversations, time and organizational management skills, team building and motivation, and financial management skills. Themes related to preferred learning methods of chief CRNAs included mentorship, peer networking, and experiential learning to obtain the required knowledge and skills for the role. The authors recommend incorporating each of the identified themes to guide development of CRNA management-specific educational programs. Establishing such a program will serve to better prepare aspiring CRNA managers and further develop the knowledge and skillset of current chief CRNAs.

Analysis of nitrogen source assimilation in industrial strains of Aspergillus oryzae.

Nitrogen source assimilation is important for the biological functions of fungi, and its pathway has been deeply studied. Aspergillus oryzae mutants defective in nitrogen source assimilation are known to grow poorly on Czapek-Dox (CD) medium. In this study, we found an industrial strain of A. oryzae that grew very poorly on a CD medium containing sodium nitrate as a nitrogen source. We used media with various nitrogen components to examine the steps affecting the nitrogen source assimilation pathway of this strain. The strain grew well on the CD medium supplied with nitrite salt or ammonium salt, suggesting that the strain was defective in nitrate assimilation step. To ascertain the gene causing the defect of nitrate assimilation, a gene expression vector harboring either niaD or crnA of A. oryzae RIB40 was introduced into the industrial strain. The industrial strain containing the crnA vector recovered its growth. This is the first report that a mutation of crnA causes poor growth on CD medium in an industrial strain of A. oryzae, and crnA can be used as a transformation marker for crnA deficient strains.

Microarray Analysis to Determine Gene Expression Changes in Zebrafish Embryos.

Chemical exposure in humans begins from the zygote stage and continues throughout the development of the embryo and the fetus. Zebrafish are one of the most powerful model organisms used in many research areas, including genetics, environmental toxicology, development, DNA damage and repair, cancer, and other diseases. Among the advantages that facilitate the use of zebrafish as a model for studies are features such as high homology with the human genome, small size, and high reproductive potential in short periods. The use of zebrafish embryos in research has increased rapidly due to their advantageous properties, including extrauterine development and the transparent feature of the embryos. However, there are thousands of genes that can be encountered in research, and in this case, the workforce is too much. This workload has been alleviated with the developed technologies. Microarray is one of these technologies. An important parameter in this assay is the RIN value. The RIN value ranges from 1 to 10, indicating mRNA degradation, and therefore helps to decide whether to continue the study. In this chapter, microarray analysis, which is one of the main techniques used in the determination of gene expression in zebrafish embryos, is described.

Certified Registered Nurse Anaesthetists' and Critical Care Registered Nurses' perception of knowledge/power in teamwork with Anaesthesiologists in Sweden: a mixed-method study.

Efficient teamwork is crucial to provide optimal health care. This paper focuses on teamwork between Anaesthesiologists (ANES), Certified Registered Nurse Anaesthetists' (CRNA) and Critical Care Registered Nurses (CCRN) working in challenging environments such as the intensive care unit (ICU) and the operating room (OR). Conflicts are common between physicians and nurses, negatively impacting teamwork. Social hierarchies based on professional status and power inequalities between nurses and physicians plays a vital role in influencing teamwork. Foucault was a famous thinker especially known for his reasoning regarding power/knowledge. A Foucauldian perspective was therefore incorporated into this paper and the overall aim was to explore CCRN/CRNA perception of knowledge/power in teamwork with ANES.Methods A mixed-method approach was applied in this study. Data was collected using a web-based questionnaire containing both closed-end and open-ended questions. A total of 289 CCRNs and CRNAs completed the questionnaire. Data analysis was then conducted through five stages as outlined by Onwuebugzie and Teddlie; analysing quantitative data in SPSS 27.0 and qualitative data with a directed content analysis, finally merging data together in ATLAS.ti v.23.Results The result reveals a dissonance between quantitative and qualitative data; quantitative data indicates a well-functioning interdisciplinary teamwork between CCRN/CRNA and ANES - qualitative data highlights that there are several barriers and inequalities between the two groups. Medicine was perceived as superior to nursing, which was reinforced by both social and organisational structures at the ICU and OR.Conclusion Unconscious rules underlying current power structures in the ICU and OR works in favour of the ANES and biomedical paradigm, supporting medical knowledge. To achieve a more equal power distribution between CCRN/CRNAs and ANES, the structural hierarchies between nursing and medicine needs to be addressed. A more equal power balance between the two disciplines can improve teamwork and thereby reduce patient mortality and improve patient outcomes.

Cognitive Preference and Clinical Experience: The Relationship Between Student Nurse Anesthetists' and Certified Registered Nurse Anesthetists' Thinking Styles.

This study examined the relationship between cognitive preference and clinical experience in student registered nurse anesthetists (SRNAs) and certified registered nurse anesthetists (CRNAs). Survey data was collected from enrolled SRNAs and practicing CRNAs via an email link distributive through a network sampling technique. Participants completed the Rational Experiential Inventory (REI-40), which assesses individuals' preference, ability, and engagement with rational and experiential cognitive styles. Data analysis revealed that SRNAs and CRNAs have the ability and engagement preference for rational decision-making. Furthermore, there was no statistical significance in years of clinical experience to cognitive preference, nor was there a statistically significant difference between SRNA and CRNA REI-40 Inventory results. Based on these findings, the dominant cognitive preference is rational cognition and experiential thinking preference remains constant with increased experience. This knowledge contributes to our understanding of CRNAs' decision-making related to cognitive processes and provides insight into SRNA clinical education and CRNA continuing development.

The Role of Liquid Biopsy in the Diagnosis and Prognosis of WHO Grade 4 Astrocytoma.

Liquid biopsy, as a non-invasive diagnostic tool, has recently gained significant attention in the field of oncology. It involves the analysis of various biomarkers present in bodily fluids, such as blood or cerebrospinal fluid, to provide information about the underlying cancer. In the case of WHO grade 4 astrocytomas, liquid biopsy has the potential to significantly impact the diagnosis and prognosis of this aggressive malignant brain tumor. By detecting specific genetic mutations, such as IDH1 or EGFR, and monitoring levels of circulating tumor DNA, liquid biopsy can aid in the early detection and monitoring of disease progression. This innovative approach is gradually being acknowledged as a less invasive and cost-effective procedure for cancer diagnosis and management to improve patient outcomes and quality of life. Various kinds of biomarkers circulating in cerebrospinal fluid (CSF), such as circulating tumor cells (CTC) and different types of nucleic acids like cell-free DNA (cfDNA), cell-free RNA (ctRNA), and microRNAs (miRNA), have been identified. These biomarkers, which require dependable detection methods, are comparatively simple to obtain and allow for repeated measurements, making them significantly superior for disease monitoring. This review aims to compare the latest liquid biopsy analysis tools for both CSF and plasma in the central nervous system.

SiftCell: A robust framework to detect and isolate cell-containing droplets from single-cell RNA sequence reads.

Single-cell RNA sequencing (scRNA-seq) massively profiles transcriptomes of individual cells encapsulated in barcoded droplets in parallel. However, in real-world scRNA-seq data, many barcoded droplets do not contain cells, but instead, they capture a fraction of ambient RNAs released from damaged or lysed cells. A typical first step to analyze scRNA-seq data is to filter out cell-free droplets and isolate cell-containing droplets, but distinguishing them is often challenging; incorrect filtering may mislead the downstream analysis substantially. We propose SiftCell, a suite of software tools to identify and visualize cell-containing and cell-free droplets in manifold space via randomization (SiftCell-Shuffle) to classify between the two types of droplets (SiftCell-Boost) and to quantify the contribution of ambient RNAs for each droplet (SiftCell-Mix). By applying our method to datasets obtained by various single-cell platforms, we show that SiftCell provides a streamlined way to perform upstream quality control of scRNA-seq, which is more comprehensive and accurate than existing methods.

Transcriptomics for Clinical and Experimental Biology Research: Hang on a Seq.

Sequencing the human genome empowers translational medicine, facilitating transcriptome-wide molecular diagnosis, pathway biology, and drug repositioning. Initially, microarrays are used to study the bulk transcriptome; but now short-read RNA sequencing (RNA-seq) predominates. Positioned as a superior technology, that makes the discovery of novel transcripts routine, most RNA-seq analyses are in fact modeled on the known transcriptome. Limitations of the RNA-seq methodology have emerged, while the design of, and the analysis strategies applied to, arrays have matured. An equitable comparison between these technologies is provided, highlighting advantages that modern arrays hold over RNA-seq. Array protocols more accurately quantify constitutively expressed protein coding genes across tissue replicates, and are more reliable for studying lower expressed genes. Arrays reveal long noncoding RNAs (lncRNA) are neither sparsely nor lower expressed than protein coding genes. Heterogeneous coverage of constitutively expressed genes observed with RNA-seq, undermines the validity and reproducibility of pathway analyses. The factors driving these observations, many of which are relevant to long-read or single-cell sequencing are discussed. As proposed herein, a reappreciation of bulk transcriptomic methods is required, including wider use of the modern high-density array data-to urgently revise existing anatomical RNA reference atlases and assist with more accurate study of lncRNAs.

A Qualitative Examination of Opioid Sparing Anesthesia Practices Among CRNAs.

PURPOSE: The purpose of this study was to examine the experiences of CRNAs using opioid sparing techniques in their perioperative anesthesia practice. DESIGN: This study used a qualitative descriptive methodology. METHODS: Semistructured individual interviews were conducted with Certified Registered Nurse Anesthetists who use opioid sparing anesthesia in their clinical practice in the United States. FINDINGS: Sixteen interviews were completed. Thematic network analysis revealed two major themes: (1) perioperative benefits of opioid sparing anesthesia and (2) prospective benefits of opioid sparing anesthesia. Perioperative benefits described include reduction or elimination of postoperative nausea and vomiting, superior pain control, and improved short-term recovery. Prospective benefits described include higher surgeon satisfaction, superior surgeon-managed pain control, increased patient satisfaction, reduction of opioids in the community, and awareness of positive prospective benefits of opioid sparing anesthesia. CONCLUSIONS: This study highlights the significance of opioid sparing anesthesia and its role in comprehensive perioperative pain control, reduction of opioids in the community, and patient recovery beyond the postanesthesia care unit.

Called to Lead: A Qualitative Examination of the Experiences and Contributions of Certified Registered Nurse Anesthetists During the COVID-19 Pandemic Response in the United States.

The COVID-19 pandemic strained healthcare providers, particularly certified registered nurse anesthetists (CRNAs). To date, little research has focused on the effects of the COVID-19 pandemic on CRNAs, whose unique skillset conferred on them expanded roles and responsibilities, increasing their stress load. Therefore, the purpose of this study was to utilize qualitative descriptive methodology to examine the experiences of CRNAs during the COVID-19 pandemic. Twelve CRNAs providing patient care in the US during the COVID-19 pandemic completed the interview protocol. Five key themes were identified including 1) roles of CRNAs, 2) collaboration, 3) challenges, 4) mental health implications for CRNAs, and 5) pride in profession. This study's descriptions of CRNA experiences during this unprecedented time in contemporary history identifies critical areas for further investigation and provides insights into anesthetic, mental health, and policy priorities to better support CRNAs now and through future infectious disease outbreaks.

Evaluating the Utilization of a Perioperative Hyperglycemic Protocol: A Quality Improvement Project.

PURPOSE: The purpose of this project to evaluate adherence to the perioperative hyperglycemic protocol among Certified Registered Nurse Anesthetists (CRNAs) at a large academic hospital. A secondary objective of this project is CRNAs' perceptions of barriers to point-of-care (POC) testing and the protocol. DESIGN: A quality improvement project. METHODS: Using Donabedian's conceptual framework, a Phase 1 retrospective chart analysis of 297 patients with diabetes undergoing noncardiac surgery before and after implementing POC testing for intraoperative glucose control was performed. Only patients with preoperative BG ≥ 180 mg/dL were included in this phase of the project, which involved a comparison of the protocol utilization before and after implementation of POC testing. Phase 2 included an assessment of CRNA's perceptions of the protocol. FINDINGS: The final sample included 91 (37 preimplementation; 54 postimplementation) participants. There were no significant demographic differences between the groups. Overall, 52.7% of patients had intraoperative glucose checks, and only 16.5% received insulin. Preoperative BG levels decreased 11.4-points, and postoperative BG levels increased 20.4 points when comparing pre- and postimplementation groups. However, there were significant differences in postoperative glucose levels, pre- and postimplementation. The survey showed that the majority (65.5%) of CRNAs identified difficulty locating the protocol as the primary barrier to utilization. CONCLUSIONS: Although all patients included in this project qualified for an intraoperative glucose check, findings revealed that only half of the patients had a glucose check and less than one fifth of the patients received insulin treatment, indicating poor adherence to the protocol. Thus, while implementing protocols is essential, utilization and adherence to the protocol are critical to improving patient outcomes. Recommendations for continued improvement include increasing protocol accessibility, staff training, compliance monitoring, and a more simple protocol structure.

Peer Support and Second Victim Programs for Anesthesia Professionals Involved in Stressful or Traumatic Clinical Events.

Modern anesthetic care is very safe, but stressful and traumatic clinical events may occur. When they occur, anesthesia professionals are vulnerable to second victim experiences, resulting in significant and long-lasting psychological and emotional consequences if not addressed. Peer support can help anesthesia professionals cope with the negative effects of second victim experiences.

A Ready Force: The U.S. Army Certified Registered Nurse Anesthetist Readiness Model.

The U.S. was at war for nearly two decades, supporting unprecedented survival on the battlefield. As the nation pivots to a relative peace, it is critical that U.S. Army certified registered nurse anesthetist (CRNA) leaders mitigate the loss of lessons learned and prepare future Army CRNAs for war. This article describes the U.S. Army CRNA Readiness Model that incorporates the knowledge, skills, and abilities required to sustain readiness. This model will provide U.S. Army nursing leaders with the framework to implement and evaluate solider readiness to provide anesthesia in operational environments.

Integrating the ASRA Pain Medicine Cannabis Consensus Guidelines into Certified Registered Nurse Anesthetist Clinical Practice.

The American Association of Nurse Anesthesiology Practice Committee and subject matter experts recently evaluated newly published cannabis guidelines titled "ASRA Pain Medicine Consensus Guidelines on the Management of the Perioperative Patient on Cannabis and Cannabinoids." A summative review of the evidence-based guidelines provides essential recommendations, which are directly applicable to certified registered nurse anesthetist clinical practice.

Innovating Student Registered Nurse Anesthetist Clinical Learning Through United States Air Force Pilot Training Practices: A Review of the Literature.

The clinical learning environment is essential for student registered nurse anesthetists (SRNAs) to develop intricate clinical knowledge and acquire proficiency in technical skills required for anesthetic care. The perioperative experience of an SRNA can differ greatly based on the program, preceptor, hospital rotation, or geographic location. This literature review synthesizes the historical and current state of certified registered nurse anesthetist (CRNA)/SRNA preceptorship in the clinical setting. Themes analyzed include the current CRNA/SRNA learning and teaching environment, student perceptions of effective CRNA preceptors, evaluation tools and feedback practices, and overall CRNA preceptor preparedness as well as the availability and effectiveness of preceptor training programs. We compare their findings to best practices seen in the United States Air Force (USAF) pilot training program because of its similar "high stakes" learning environment and utilization of a preceptor teaching model. Actionable recommendations, based on CRNA preceptorship data, preceptorship theory, and the USAF pilot training model are presented in the effort to improve preceptor transfer of knowledge and SRNA clinical competence.

Overview of Preoperative Risk Analysis: American Society of Anesthesiology Physical Status Classification and the Surgical Risk Calculator.

The certified registered nurse anesthetist has a vital role and critical position to provide safe and effective anesthesia and to speak on behalf of the patient when they cannot speak for themselves. Paramount to this process is analyzing risk factors related to the patient's physical status, the specific surgical procedure, and the method of anesthesia delivery. The American Society of Anesthesiology Physical Status Classification is a foundation in preoperative patient assessment. This preoperative assessment tool is used for assessing patient's functional reserve and risk for anesthesia. The American College of Surgeons National Surgical Quality Improvement Program developed the Surgical Risk Calculator. This preoperative assessment tool uses 21 preoperative risk factors to predict 13 perioperative complications and is proving to be a reliable indicator for predicting patient risk. Anesthetic techniques such as multimodal analgesia and enhanced recovery after surgery have demonstrated a significant impact on patient outcomes. There are potential improvements and opportunities for anesthesia providers to collaborate and improve patient risk analysis.

Trends in nationwide incidence of pediatric type 1 diabetes in Montenegro during the last 30 years.

Significant and unexplained variations in type 1 diabetes (T1D) incidence through the years were observed all around the world. The update on this disorder's incidence is crucial for adequate healthcare resource planning and monitoring of the disease. The aim of this study was to give an update on the current incidence of pediatric T1D in Montenegro and to analyze incidence changes over time and how the exposure to different factors might have affected it. This retrospective cohort study included a total of 582 patients younger than 15 years who were newly diagnosed with T1D during the past 30 years. The average age at diagnosis was 8.4 ± 3.91 years. The mean annual incidence of T1D in the Montenegro population during the whole study period of 30 years was 15.2/100,000 person-years. Slightly higher incidence rates were observed in male compared to female individuals, and the incidence increased with age, with the highest incidence in the 10-14 age group. If the model is observed as one without jointpoints, the annual percentage change (APC) for the total population is 3.1 (1.8-4.4); for male individuals, 3.8 (2.1-5.5); and for female individuals, 2.1 (0.6-3.5). In 2020, the first year of the coronavirus disease of 2019 (COVID-19) pandemic, in comparison to 2019, the incidence rate increased from 19.7/100,000 to 21.5/100,000, with the highest increase in the age group of 5-9 years. This is the first nationwide report on a 30-year period of T1D incidence trend in Montenegro. It suggests that T1D incidence among Montenegrin children is rising again and that there is a short-term influence of COVID-19 on new-onset T1D.

CRNA Engagement During the COVID-19 Crisis: Optimization of Resource Management, Organizational Climate, and Contributions to Care.

COVID-19 has a strong hold on New York City, and it has similar effects on other areas of the country. As COVID-19 strains healthcare systems and the certified registered nurse anesthetists (CRNAs) who work within them, optimization of CRNA organizational climate promotes transformation of care delivery and may positively impact provider and patient outcomes. This article describes one healthcare system's newly refined processes for managing the surge of COVID-19 patients. It also describes the novel contributions of CRNAs to all aspects of care provision from supply and resource management to management of patients in critical care environments, to refinement of intubation and airway management for this patient population. Lessons learned during this pandemic from two facilities within this healthcare system are described. When a healthcare system's culture respects and encourages collaboration and innovation, dynamic changes can be implemented effectively during times of crises. Also, critically helpful is when CRNA organizational climate promotes equal partnerships with physicians, and administration values the CRNA contributions to care. In this case, collaboration of all stakeholders promoted best practices and improved care provision. Lessons learned may be applied to facilities where the COVID-19 surge is occurring.
