Evaluating ChatGPT's moral competence in health care-related ethical problems.

Objectives: Artificial intelligence tools such as Chat Generative Pre-trained Transformer (ChatGPT) have been used for many health care-related applications; however, there is a lack of research on their capabilities for evaluating morally and/or ethically complex medical decisions. The objective of this study was to assess the moral competence of ChatGPT. Materials and methods: This cross-sectional study was performed between May 2023 and July 2023 using scenarios from the Moral Competence Test (MCT). Numerical responses were collected from ChatGPT 3.5 and 4.0 to assess individual and overall stage scores, including C-index and overall moral stage preference. Descriptive analysis and 2-sided Student's t-test were used for all continuous data. Results: A total of 100 iterations of the MCT were performed and moral preference was found to be higher in the latter Kohlberg-derived arguments. ChatGPT 4.0 was found to have a higher overall moral stage preference (2.325 versus 1.755) when compared to ChatGPT 3.5. ChatGPT 4.0 was also found to have a statistically higher C-index score in comparison to ChatGPT 3.5 (29.03 ± 11.10 versus 19.32 ± 10.95, P =.0000275). Discussion: ChatGPT 3.5 and 4.0 trended towards higher moral preference for the latter stages of Kohlberg's theory for both dilemmas with C-indices suggesting medium moral competence. However, both models showed moderate variation in C-index scores indicating inconsistency and further training is recommended. Conclusion: ChatGPT demonstrates medium moral competence and can evaluate arguments based on Kohlberg's theory of moral development. These findings suggest that future revisions of ChatGPT and other large language models could assist physicians in the decision-making process when encountering complex ethical scenarios.

A comparative study of small-scale fishery supply chains' vulnerability and resilience to COVID-19.

The COVID-19 pandemic and response has significantly disrupted fishery supply chains, creating shortages of essential foods and constraining livelihoods globally. Small-scale fisheries (SSFs) are responding to the pandemic in a variety of ways. Together, disruptions from and responses to COVID-19 illuminate existing vulnerabilities in the fish distribution paradigm and possible means of reducing system and actor sensitivity and exposure and increasing adaptive capacity. Integrating concepts from literature on supply chain disruptions, social-ecological systems, human wellbeing, vulnerability, and SSFs, we synthesize preliminary lessons from six case studies from Indonesia, the Philippines, Peru, Canada, and the United States. The SSF supply chains examined employ different distribution strategies and operate in different geographic, political, social, economic, and cultural contexts. Specifically, we ask (a) how resilient have different SSF supply chains been to COVID-19 impacts; (b) what do these initial outcomes indicate about the role of distribution strategies in determining the vulnerability of SSF supply chains to macroeconomic shocks; and (c) what key factors have shaped this vulnerability? Based on our findings, systemic changes that may reduce SSF vulnerability to future macroeconomic shocks include: diversification of distribution strategies, livelihoods, and products; development of local and domestic markets and distribution channels; reduced reliance on international markets; establishment of effective communication channels; and preparation for providing aid to directly assist supply chains and support consumer purchasing power.

Trapped by a first hypothesis: How rudeness leads to anchoring.

In this article we explore the effect of encounters with rudeness on the tendency to engage in anchoring, one of the most robust and widespread cognitive biases. Integrating the self-immersion framework with the selective accessibility model (SAM), we propose that rudeness-induced negative arousal will narrow individuals' perspectives in a way that will make anchoring more likely. Additionally, we posit that perspective taking and information elaboration will attenuate the effect of rudeness on both negative arousal and subsequent anchoring. Across four experimental studies, we test the impact of exposure to rudeness on anchoring as manifested in a variety of tasks (medical diagnosis, judgment tasks, and negotiation). In a pilot study, we find that rudeness is associated with anchoring among a group of medical students making a medical diagnosis. In Study 1, we show that negative arousal mediates the effect of rudeness on anchoring among medical residents treating a patient, and that perspective taking moderates these effects. Study 2 replicates the results of Study 1 using a common anchoring task, and Study 3 builds on these results by replicating them in a negotiation setting and testing information elaboration as a boundary condition. Across the four studies, we find consistent evidence that rudeness-induced negative arousal leads to anchoring, and that these effects can be mitigated by perspective taking and information elaboration.

Preliminary lessons from COVID-19 disruptions of small-scale fishery supply chains.

The ongoing COVID-19 pandemic and associated mitigation measures have disrupted global systems that support the health, food and nutrition security, and livelihoods of billions of people. These disruptions have likewise affected the small-scale fishery (SSF) sector, disrupting SSF supply chains and exposing weaknesses in the global seafood distribution system. To inform future development of adaptive capacity and resilience in the sector, it is important to understand how supply chain actors are responding in the face of a macroeconomic shock. Comparing across seven SSF case studies in four countries, we explore how actors are responding to COVID-19 disruptions, identify constraints to adaptive responses, and describe patterns of disruption and response across cases. In all cases examined, actors shifted focus to local and regional distribution channels and particularly drew on flexibility, organization, and learning to re-purpose pre-existing networks and use technology to their advantage. Key constraints to reaching domestic consumers included domestic restrictions on movement and labor, reduced spending power amongst domestic consumers, and lack of existing distribution channels. In addition, the lack of recognition of SSFs as essential food-producers and inequities in access to technology hampered efforts to continue local seafood supply. We suggest that the initial impacts from COVID-19 highlight the risks in of over-reliance on global trade networks. The SSFs that were able to change strategies most successfully had local organizations and connections in place that they leveraged in innovative ways. As such, supporting local and domestic networks and flexible organizations within the supply chain may help build resilience in the face of future macroeconomic shocks. Importantly, bolstering financial wellbeing and security within the domestic market both before and during such large-scale disruptions is crucial for supporting ongoing supply chain operations and continued food provision during macroeconomic crises.

Vitamin B12 for the treatment of vasoplegia in cardiac surgery and liver transplantation: a narrative review of cases and potential biochemical mechanisms.

PURPOSE: Hydroxocobalamin, or vitamin B12 (V-B12), is frequently used to treat smoke inhalation and cyanide poisoning. Recent reports have also described its use to treat vasoplegia in cardiac surgery and liver transplantation. This narrative review discusses this "off-label" indication for V-B12, focusing on the potential biochemical mechanisms of its actions. SOURCE: PubMed, Cochrane, and Web of Science databases were searched for clinical reports on the use of V-B12 for vasoplegia in cardiac surgery and liver transplantation, with the biochemical mechanisms discussed being based on a survey of the related biochemistry literature. PRINCIPAL FINDINGS: Forty-four patients have been treated with V-B12 for vasoplegia in various isolated case reports and one series. Although 75% of patients have increased blood pressure in response to V-B12, there were some "non-responders". The true efficacy remains unknown because clinical trials have not been performed, and significant reporting bias likely exists. Plausible biochemical explanations exist for the potential beneficial effects of V-B12 in treating vasoplegia, including binding nitric oxide and other gasotransmitters. Additional research is required to clarify if and how these mechanisms are causally involved in effective clinical responders and non-responders. CONCLUSIONS: Although anecdotal reports utilizing V-B12 for vasoplegia are available, no higher-level evidence exists. Future work is necessary to further understand the dosing, timing, adverse events, and biochemical mechanisms of V-B12 compared with other therapies such as methylene blue.

Emergency Department Airway Management Responsibilities in the United States.

BACKGROUND: In the 1990s, emergency medicine (EM) physicians were responsible for intubating about half of the patients requiring airway management in emergency rooms. Since then, no studies have characterized the airway management responsibilities in the emergency room. METHODS: A survey was sent via the Eastern Association for Surgery and Trauma and the Trauma Anesthesiology Society listservs, as well as by direct solicitation. Information was collected on trauma center level, geographical location, department responsible for intubation in the emergency room, department responsible for intubation in the trauma bay, whether these roles differed for pediatrics, whether an anesthesiologist was available "in-house" 24 hours a day, and whether there was a protocol for anesthesiologists to assist as backup during intubations. Responses were collected, reviewed, linked by city, and mapped using Python. RESULTS: The majority of the responses came from the Eastern Association for Surgery of Trauma (84.6%). Of the respondents, 72.6% were from level-1 trauma centers, and most were located in the eastern half of the United States. In the emergency room, EM physicians were primarily responsible for intubations at 81% of the surveyed institutions. In trauma bays, EM physicians were primarily responsible for 61.4% of intubations. There did not appear to be a geographical pattern for personnel responsible for managing the airway at the institutions surveyed. CONCLUSIONS: The majority of institutions have EM physicians managing their airways in both emergency rooms and trauma bays. This may support the observations of an increased percentage of airway management in the emergency room and trauma bay setting by EM physicians compared to 20 years ago.

Understanding Conflict Management Styles in Anesthesiology Residents.

BACKGROUND: Successful conflict resolution is vital for effective teamwork and is critical for safe patient care in the operating room. Being able to appreciate the differences in training backgrounds, individual knowledge and opinions, and task interdependency necessitates skilled conflict management styles when addressing various clinical and professional scenarios. The goal of this study was to assess conflict styles in anesthesiology residents via self- and counterpart assessment during participation in simulated conflict scenarios. METHODS: Twenty-two first-year anesthesiology residents (first postgraduate year) participated in this study, which aimed to assess and summarize conflict management styles by 3 separate metrics. One metric was self-assessment with the Thomas-Kilmann Conflict Mode Instrument (TKI), summarized as percentile scores (0%-99%) for 5 conflict styles: collaborating, competing, accommodating, avoiding, and compromising. Participants also completed self- and counterpart ratings after interactions in a simulated conflict scenario using the Dutch Test for Conflict Handling (DUTCH), with scores ranging from 5 to 25 points for each of 5 conflict styles: yielding, compromising, forcing, problem solving, and avoiding. Higher TKI and DUTCH scores would indicate a higher preference for a given conflict style. Sign tests were used to compare self- and counterpart ratings on the DUTCH scores, and Spearman correlations were used to assess associations between TKI and DUTCH scores. RESULTS: On the TKI, the anesthesiology residents had the highest median percentile scores (with first quartile [Q1] and third quartile [Q3]) in compromising (67th, Q1-Q3 = 27-87) and accommodating (69th, Q1-Q3 = 30-94) styles, and the lowest scores for competing (32nd, Q1-Q3 = 10-57). After each conflict scenario, residents and their counterparts on the DUTCH reported higher median scores for compromising (self: 16, Q1-Q3 = 14-16; counterpart: 16, Q1-Q3 = 15-16) and problem solving (self: 17, Q1-Q3 = 16-18; counterpart: 16, Q1-Q3 = 16-17), and lower scores for forcing (self: 13, Q1-Q3 = 10-15; counterpart: 13, Q1-Q3 = 13-15) and avoiding (self: 14, Q1-Q3 = 10-16; counterpart: 14.5, Q1-Q3 = 11-16). There were no significant differences (P > .05) between self- and counterpart ratings on the DUTCH. Overall, the correlations between TKI and DUTCH scores were not statistically significant (P > .05). CONCLUSIONS: Findings from our study demonstrate that our cohort of first postgraduate year anesthesiology residents predominantly take a more cooperative and problem-solving approach to handling conflict. By understanding one's dominant conflict management style through this type of analysis and appreciating the value of other styles, one may become better equipped to manage different conflicts as needed depending on the situations.

Resident Physicians Improve Nontechnical Skills When on Operating Room Management and Leadership Rotation.

BACKGROUND: Anesthesiology residency primarily emphasizes the development of medical knowledge and technical skills. Yet, nontechnical skills (NTS) are also vital to successful clinical practice. Elements of NTS are communication, teamwork, situational awareness, and decision making. METHODS: The first 10 consecutive senior residents who chose to participate in this 2-week elective rotation of operating room (OR) management and leadership training were enrolled in this study, which spanned from March 2013 to March 2015. Each resident served as the anesthesiology officer of the day (AOD) and was tasked with coordinating OR assignments, managing care for 2 to 4 ORs, and being on call for the trauma OR; all residents were supervised by an attending AOD. Leadership and NTS techniques were taught via a standardized curriculum consisting of leadership and team training articles, crisis management text, and daily debriefings. Resident self-ratings and attending AOD and charge nurse raters used the Anaesthetists' Non-Technical Skills (ANTS) scoring system, which involved task management, situational awareness, teamwork, and decision making. For each of the 10 residents in their third year of clinical anesthesiology training (CA-3) who participated in this elective rotation, there were 14 items that required feedback from resident self-assessment and OR raters, including the daily attending AOD and charge nurse. Results for each of the items on the questionnaire were compared between the beginning and the end of the rotation with the Wilcoxon signed-rank test for matched samples. Comparisons were run separately for attending AOD and charge nurse assessments and resident self-assessments. Scaled rankings were analyzed for the Kendall coefficient of concordance (ω) for rater agreement with associated χ and P value. RESULTS: Common themes identified by the residents during debriefings were recurrence of challenging situations and the skills residents needed to instruct and manage clinical teams. For attending AOD and charge nurse assessments, resident performance of NTS improved from the beginning to the end of the rotation on 12 of the 14 NTS items (P < .05), whereas resident self-assessment improved on 3 NTS items (P < .05). Interrater reliability (across the charge nurse, resident, and AOD raters) ranged from ω = .36 to .61 at the beginning of the rotation and ω = .27 to .70 at the end of the rotation. CONCLUSIONS: This rotation allowed for teaching and resident assessment to occur in a way that facilitated resident education in several of the skills required to meet specific milestones. Resident physicians are able to foster NTS and build a framework for clinical leadership when completing a 2-week senior elective as an OR manager.

Hypertensive Crisis From the Aquamantys Bipolar Sealing System.

Hypertension is a common occurrence during general anesthesia. Apart from pathological causes of hypertension, it is rarely extreme enough to be classified as a hypertensive crisis (systolic blood pressure >180 mm Hg or diastolic blood pressure >120 mm Hg). There is literature concerning the unintentional electrocauterization of the adrenal gland leading to hypertensive crisis, but to date, no reports have been made of adrenal stimulation from the use of an Aquamantys for hemostasis. Here, we report such a case when a hypertensive crisis (systolic blood pressure >300 mm Hg) occurred while using an Aquamantys during a liver transplant after unintentional stimulation of the adrenal glands.

Prospective Comprehensive Swallowing Evaluation of Minimally Invasive Esophagectomies with Cervical Anastomosis: Silent Versus Vocal Aspiration.

INTRODUCTION: Pneumonia and tracheal aspiration remain problematic following esophagectomy. We hypothesized that the incidence of postesophagectomy pneumonia occurs in part because of swallowing dysfunction and more importantly silent tracheobronchial aspiration. Therefore, we instituted a routine prospective formal swallowing evaluation to determine if the aspiration rate and its associated morbidity can be decreased by early identification of patients with silent or vocal aspiration. METHODS: Patients undergoing minimally invasive McKeown esophagectomy and receiving neoadjuvant chemoradiotherapy (NACR) were prospectively enrolled between December 2013 to January 2015. A standardized cineradiography observation utilizing the Rosenbek penetration-aspiration (RPA) scale was used to rule out anastomotic leak and/or aspiration. RESULTS: Of 27 patients evaluated, twelve patients were noted to have silent (n = 8) or vocal (cough n = 4) aspiration of thin liquid (n = 8) or nectar-thick consistency (n = 4) on their initial study. Three patients were noted to have an anastomotic leak and vocal aspiration on their initial study. Eight of the nine patients who aspirated but did not have an anastomotic leak on their initial study had a repeat RPA study prior to discharge showing improvement from the initial study. Six patients (22 %) had vocal cord paresis and clinical hoarseness, but only two patients who had clinical diagnosis of pneumonia were noted to have vocal cord paresis and silent aspiration. CONCLUSIONS: Swallowing dysfunction remains a common problem after minimally invasive esophagectomy (MIE) with cervical anastomosis and can be readily identified. Silent aspiration likely contributes to pneumonia after MIE.

Site selection in global clinical trials in patients hospitalized for heart failure: perceived problems and potential solutions.

There are over 1 million hospitalizations for heart failure (HF) annually in the United States alone, and a similar number has been reported in Europe. Recent clinical trials investigating novel therapies in patients with hospitalized HF (HHF) have been negative, and the post-discharge event rate remains unacceptably high. The lack of success with HHF trials stem from problems with understanding the study drug, matching the drug to the appropriate HF subgroup, and study execution. Related to the concept of study execution is the importance of including appropriate study sites in HHF trials. Often overlooked issues include consideration of the geographic region and the number of patients enrolled at each study center. Marked differences in baseline patient co-morbidities, serum biomarkers, treatment utilization and outcomes have been demonstrated across geographic regions. Furthermore, patients from sites with low recruitment may have worse outcomes compared to sites with higher enrollment patterns. Consequently, sites with poor trial enrollment may influence key patient end points and likely do not justify the costs of site training and maintenance. Accordingly, there is an unmet need to develop strategies to identify the right study sites that have acceptable patient quantity and quality. Potential approaches include, but are not limited to, establishing a pre-trial registry, developing site performance metrics, identifying a local regionally involved leader and bolstering recruitment incentives. This manuscript summarizes the roundtable discussion hosted by the Food and Drug Administration between members of academia, the National Institutes of Health, industry partners, contract research organizations and academic research organizations on the importance of selecting optimal sites for successful trials in HHF.

Deep vein thrombosis: endovascular management.

Deep vein thrombosis is a condition that affects hundreds of thousands of patients each year. The major complications include pulmonary embolus with the potential for loss of life and post-thrombotic syndrome with the potential for loss of function of the limb. Extensive clinical research over the last 40 years has improved the techniques to remove the thrombus from the affected limb and reduce the likelihood of developing post-thrombotic syndrome. These treatments have included intravenous systemic thrombolysis, catheter-directed thrombolysis, surgical thrombectomy, and most recently pharmacomechanical thrombectomy to rapidly fragment, lyse, and remove the thrombus from the affected limb. This last technique may finally transform the treatment of acute deep vein thrombus from strictly conservative medical therapy to a minimally invasive procedure that can remove the thrombus to improve the quality of life of millions of individuals suffering from the symptoms of deep vein thrombosis.
