Clinical easoning nveiled: demystifying Heuristics and hermeneutics in neurological clinical practice / Raciocínio clínico desvendado: desmistificando heurística e hermenêutica na prática clínica neurológica

Introduction: Medical practice, particularly in Neurology, is often influenced by cognitive biases that can compromise diagnostic and therapeutic accuracy, leading to significant patient consequences. Clinical reasoning strategies are fundamental, yet the complexity of these processes is frequently underestimated. Understanding these strategies is crucial to ensure accurate diagnoses and effective treatments, thereby reducing clinical errors and optimizing patient outcomes. Despite extensive literature on cognitive biases, there is a need for a systematic synthesis addressing the peculiarities of neurological clinical reasoning, considering heuristics (mental shortcuts or rules of thumb that simplify decision-making) and hermeneutics (the theory and methodology of interpretation, especially of textual and symbolic content). Objectives: To review and systematize the main clinical reasoning strategies in Neurology, highlighting common biases and proposing methods to improve diagnostic and therapeutic accuracy. Methodology: A comprehensive literature review focusing on familiarity biases, Dual Process Theory, and heuristics (anchoring, availability, and representativeness). Additionally, the application of hermeneutics in hypothesis formulation and the importance of understanding the patient as a complex system were analyzed. Results: Specialized neurologists often rely on heuristics, which means a cognitive shortcut. Recognizing this process can mitigate anchoring and availability biases. The hermeneutic approach, on the other hand, is essential for interpreting variables in the patient's context, integrating historical and social aspects. Conclusion: Understanding clinical reasoning processes and systematically teaching these strategies are crucial to enhancing the efficiency and effectiveness of clinical decision-making, reducing diagnostic errors, and improving patient outcomes.

Introdução: A prática médica, particularmente em Neurologia, é frequentemente influenciada por vieses cognitivos que podem comprometer a precisão diagnóstica e a terapêutica, resultando em consequências significativas para o paciente. Estratégias de raciocínio clínico são fundamentais, mas a complexidade desses processos é subestimada. Compreendê-las é crucial para garantir diagnósticos precisos e tratamentos eficazes, reduzindo erros e otimizando resultados. Apesar da extensa literatura sobre vieses cognitivos, necessita-se sintetizar sistematicamente uma abordagem das peculiaridades do raciocínio neurológico, considerando heurísticas (atalhos mentais ou regras práticas que simplificam a tomada de decisão) e a hermenêutica (a teoria e metodologia de interpretação, especialmente de conteúdo textual e simbólico). Objetivos: Revisar e sistematizar as principais estratégias de raciocínio clínico em Neurologia, destacando os vieses comuns e propondo métodos para melhorar a precisão diagnóstica e terapêutica. Metodologia: Uma revisão abrangente da literatura focando em vieses de familiaridade, Teoria do Processo Dual e heurísticas (ancoragem, disponibilidade e representatividade). Além disso, a aplicação da hermenêutica na formulação de hipóteses e a importância de entender o paciente como um sistema complexo foram analisadas. Resultados: Neurologistas especializados frequentemente dependem de heurísticas, que são atalhos cognitivos. Reconhecer esse processo pode mitigar os vieses de ancoragem e disponibilidade. A abordagem hermenêutica é essencial para interpretar variáveis no contexto do paciente, integrando aspectos históricos e sociais. Conclusão: Compreender os processos de raciocínio clínico e ensinar sistematicamente essas estratégias é crucial para aumentar a eficiência e eficácia da tomada de decisões, reduzindo erros e melhorando os resultados dos pacientes.

Determinants of data-driven decision-making among health providers: a case of Mombasa county, Kenya

Background: Healthcare professionals understand how important it is to turn health data into information for informed decision-making. However, a lack of trustworthy and up-to-date health information is caused by inadequate investment in infrastructure for data collection, analysis, dissemination, and use. The aim of the study was to determine data-driven decision-making among health providers, a case of Mombasa County, Kenya. Methods: The study employed an analytical cross-sectional study design where a stratified random sampling approach was utilized to recruit respondents into the study. The Yamane formula of sample size calculation was used to recruit 168 study partakers for this study. Results: The outcomes indicated that quality data-driven decision-making exhibited a substantial correlation with technical factors (r=0.642, p value=0.000). Furthermore, the findings highlighted a significant correlation between quality data-driven decision-making and behavioral factors (r=0.821, p value=0.000). Additionally, the study's results revealed a marked correlation between quality data-propelled decision-making alongside organizational factors (r=0.819, p value=0.000). Conclusions: The likelihood ratio tests demonstrated that both technical and organizational factors significantly predicted data-driven decision-making among health providers, whereas behavioral factors did not have a statistically significant impact. There is a need to provide training for health workers at the county level to enhance data utilization skills, ensure thorough data verification before submission, and promote the use of health information in decision-making.

The application of bioethics as legal basis in judicial sentences concerning right to health in Brazil

The right to health is linked to life and human dignity. Among the instruments to make it effective, the phenomenon of health litigation has become prominent. In Brazil, courts are increasingly faced with the task of rendering verdicts concerning matters related to health. Nowadays, judges have to deal with issues about health policies, technology incorporations, drug supplies, human autonomy, genetics, and biotechnologies, among others. Lawsuit sentences are now to be built upon the resolution of ethical, legal and philosophical questions. Bioethics presents itself as an instrument and method to help solve legal cases involving the right to health. This paper intends to show that bioethics can be applied in verdicts of lawsuits regarding to right to health in Brazil. It highlights that bioethics can be considered a source of law due to its normative dimension, as well as a hermeneutic method. This essay also aims to show the role for bioethics to help interpret the law and solve hard cases within health law and the right to health. Lastly, it aims to justify the presence of bioethics as legal reasoning to be used by judges in the foundation of their verdicts in lawsuits involving the right to health.

Factors associated with decision-making on family planning use among women aged 15-49 in Guinea

Background: In Guinea, several factors affect women's ability to make decisions about contraceptive use. The objective of this study was to identify factors associated with married women's decision-making power regarding family planning use in Guinea.Methods: Data from the 2018 Guinea Demographic and Health Survey were used. A sample of 752 women was included in the study. Multivariate logistic regression was performed to determine the factors associated with women's decision-making power regarding the use of family planning in Guinea. The Odd ratio with 95% confidence interval was calculated for the variables in the final model.Results: The overall prevalence of women deciding to use family planning was 65.47% [95%CI: 62.18 68.61]. Urban women had a 49% lower chance of deciding to use family planning than rural women (adjusted OR=0.61; 95% CI [0.238 0.92]). Similarly, women with secondary education were 3.53 times more likely to use family planning than those with no formal education (adjusted OR=3.53; 95% CI [1.27 9.78]).Conclusions: This study shows the importance of several factors in women's decision-making power regarding family planning use in Guinea. Women with secondary education, those in the Kindia and Kankan regions, and those with a job had higher probability of deciding to use family planning. Findings from this study could help guide public health policies, emphasising the importance of education, employment and access to health services in improving women's decision-making power when it comes to family planning in the Republic of Guinea.

Developing a breast cancer screening decision aid in Spanish for average-risk women: a mixed methods study / Desarrollo de una herramienta en español para ayudar en la toma de decisiones del cribado de cáncer de mama para mujeres de riesgo promedio: un estudio de métodos mixtos

INTRODUCTION: We aimed to develop a decision aid to support shared-decision making between physicians and women with average breast cancer risk when deciding whether to participate in breast cancer screening. METHODS: We included women at average risk of breast cancer and physicians involved in supporting the decision of breast cancer screening from an Academic Hospital in Buenos Aires, Argentina. We followed the International Patient Decision Aid Standards to develop our decision aid. Guided by a steering group and a multidisciplinary consultancy group including a patient advocate, we reviewed the evidence about breast cancer screening and previous decision aids, explored the patients' information needs on this topic from the patients' and physicians' perspective using semi-structured interviews, and we alpha-tested the prototype to determine its usability, comprehensibility and applicability. RESULTS: We developed the first prototype of a web-based decision aid to use during the clinical encounter with women aged 40 to 69 with average breast cancer risk. After a meeting with our consultancy group, we developed a second prototype that underwent alpha-testing. Physicians and patients agreed that the tool was clear, useful and applicable during a clinical encounter. We refined our final prototype according to their feedback. CONCLUSION: We developed the first decision aid in our region and language on this topic, developed with end-users' input and informed by the best available evidence. We expect this decision aid to help women and physicians make shared decisions during the clinical encounter when talking about breast cancer screening.

Objectives:To analyze the performance and characteristics of adolescent suicide attempters in dif-ferent dimensions of decision making,a computational model was used in this study.Methods:A total of 70 adoles-cent suicide attempters with mood disorders meeting the International Statistical Classification of Diseases and Re-lated Health Problems,Tenth Revision(ICD-10)diagnosis,40 non-suicide attempters with mood disorder,and 49 normal controls were included.By using the MCQ and IGT and through computational model analysis,the adoles-cent suicide attempters'performance and underlying cognitive components in impulsive decision making and value-and learning-based decision making were analyzed.Results:The overall delay discounting rates showed no signifi-cant differences(P＞0.05)among the group of suicide attempters,patient controls,and normal controls in the MCQ.This rate was significantly higher in suicide attempters and non-suicide attempters than in normal controls(P＜0.05);there was no significant difference between the three groups of subjects'decision making performance in the IGT(P＞0.05).Computational model analysis revealed that compared to non-suicide attempters and normal controls,suicide attempters showed reduced sensitivity to the outcome as well as reduced exploratory behavior(Pa-rameter estimate with non-overlapping 80％HDI).Conclusion:Adolescent suicide attempters may not be able to learn from the outcome of the decision and explore more possible options to resolve the crisis,as well as impulsive decision-making impairment may be associated with depressed states rather than suicide attempts.

Functional magnetic resonance imaging study on activity intensity of reward brain areas under uncertain decision-making in patients with depression / 中华行为医学与脑科学杂志

Objective:To explore the brain activation intensity changes of depressed patients in the phase of expected value (EV), positive prediction error (+ PE) and negative prediction error (-PE) under uncertain (risky, ambiguous) decision-making.Methods:From July 2018 to February 2021, a total of 48 depressed patients in the Affiliated Hospital of Qingdao University were collected (depression group), and 69 sex-, age-, and educational level-matched healthy people were recruited as the control group. All participants completed risky and ambiguous decision-making tasks under the E-Prime system.SA-9800 brain functional audio-visual stimulation system and GE3.0 T functional magnetic resonance imaging (fMRI) scanners were used to conduct synchronous scanning and data acquisition. Using Xjview software to analyze the activation intensity of related brain areas to compare the activity intensity of the two groups.SPSS 16.0 software was used for chi square test, independent sample t-test. Results:Under risky decision-making, compared with the control group, the brain areas with reduced activation during EV phase in depression group were bilateral prefrontal cortex (PFC)(MNI coordinate: left x=-45, y=21, z=-6; right x=0, y=69, z=-3), left para hippocampal gyrus(PHG)(MNI coordinate: x=-9, y=0, z=-22), bilateral occipital lobe(OL)(MNI coordinate: left x=-51, y=-81, z=-3; right x=48, y=-84, z=-9)( P<0.05). The brain areas with reduced activation during + PE phase were bilateral PFC, left hippocampus (HIP), bilateral temporal lobe (TL), left middle occipital gyrus( P<0.05). The brain areas with reduced activation were bilateral PFC, right putamen, bilateral TL( P<0.05) during -PE phase. Under ambiguous decision-making, compared with the control group, the brain areas with reduced activation during EV phase in depression group were bilateral PFC, right OL( P<0.05); the brain areas with reduced activation during + PE phase were bilateral PFC, right putamen and hippocampus, bilateral TL, bilateral OL( P<0.05); and the brain areas with reduced activation were bilateral PFC, bilateral TL( P<0.05) during -PE phase. Conclusion:The study shows that the activities of reward brain areas such as PFC, limbic system and OL system are reduced during EV and PE phase under uncertain decision-making in depressed patients.

The correlation between thrombolysis decision-making anxiety and decision-making duration among surrogate decision-makers of patients with acute ischemic stroke / 中华行为医学与脑科学杂志

Objective:To explore the anxiety level, influencing factors among surrogate decision-makers of patients with acute ischemic stroke during thrombolysis decision-making, and their correlation with decision-making duration.Methods:Acute ischemic stroke patients and their surrogate decision-makers who visited the Emergency Department of the First Affiliated Hospital of Zhengzhou University from September 2019 to December 2021 were selected as the research subjects.Sociodemographic data and disease related data of patients and surrogate decision-makers were collected.Surrogate decision-makers were evaluated with the state-trait anxiety inventory, decision participation expectation scale, Wake Forest physician trust scale, and perceived social support scale.SPSS 26.0 software was used for data processing.Pearson correlation analysis, Spearman correlation analysis and ridge regression analysis were used for statistical analysis.Results:The score of state anxiety of decision-makers was (49.47±9.04), and 18.2% (70/383) of decision-makers had a decision duration exceeding 15 minutes.The score of state anxiety of decision-makers was positively correlated with decision duration ( r=0.189, P<0.001). The influencing factors of state anxiety level of decision-makers included sociodemographic factors (age of decision-makers and patients, relationship between payers and patients, whether decision-makers bear the current medical expenses, type of medical insurance for patients), psychological factors (trust level in physicians, perceived social support), factors related to patient disease (numbers of stroke relapses, National Institutes of Health stroke scale scores for patients), characteristics of the decision-making process (whether patients participate in the decision-making process, and the role of decision-makers in the decision-making process) (all P<0.05). Conclusion:Most surrogate decision-makers experience anxiety.Medical staff should pay attention to the emotions of decision-makers and adopt appropriate communication skills when communicating with informed consent for thrombolysis, alleviate the anxiety of surrogate decision-makers, so as so reduce the decision-making duration.

Research status and inspiration on decision-making dilemmas on family members of intensive care unit patients / 中国医学伦理学

Due to the particularity of the Intensive Care Unit(ICU)environment,the visiting time of family members is strictly limited,resulting in family members being unable to communicate with patients in time to understand their wishes and preferences.Moreover,the sudden onset of the diseases and clinical uncertainty can easily lead to ambivalence among family members in decision-making,leading to decision-making dilemmas.This paper reviewed the concepts,assessment tools,causes,effects,and coping strategies of decision-making dilemmas for family members of ICU patients,with a view to providing a theoretical basis for future intervention in decision-making dilemmas for family members of ICU patients,improving their quality of agency decision-making,shortening patient hospitalization time,improving the health outcomes of patients,and ultimately increasing the satisfaction of medical and nursing.
