Medical and nursing clinical decision making: a comparative epistemological analysis

Individualized Diagnosis and Prescription in Traditional Medicine: Decision-Making Process Analysis and Machine Learning-Based Analysis Tool Development

While pattern identification (PI) is an essential process in traditional medicine (TM), it is difficult to objectify since it relies heavily on implicit knowledge. Therefore, this study aimed to propose a machine learning (ML)-based analysis tool to evaluate the clinical decision-making process of PI in terms of explicit and implicit knowledge, and to observe the actual process by which this knowledge affects the choice of diagnosis and treatment in individual TM doctors. Clinical data for the development of the analysis tool were collected using a questionnaire administered to allergic rhinitis (AR) patients and the diagnosis and prescription results of TM doctors based on the completed AR questionnaires. Explicit knowledge and implicit knowledge were defined based on the doctors' explicit scoring and feature evaluations of ML models, respectively. There were many differences between the explicit and implicit importance scores in this study. Implicit importance is more closely related to explicit importance in prescription than in diagnosis. The analysis results for eight doctors showed that our tool could successfully identify explicit and implicit knowledge in the PI process. This is the first study to evaluate the actual process by which explicit and implicit knowledge affect the choice of individual TM doctors and to identify assessment tools for the definition of the decision-making process in diagnosing PI and prescribing herbal treatments by TM clinicians. The assessment tool suggested in this study could be broadly used for the standardization of precision medicine, including TM therapeutics.

Clinical reasoning as midwifery: A Socratic model for shared decision making in person-centred care

Shared decision making has become the standard of care, yet there remains no consensus about how it should be conducted. Most accounts are concerned with threats to patient autonomy, and they address the dangers of a power imbalance by foregrounding the patient as a person whose complex preferences it is the practitioner's task to support. Other corrective models fear that this level of mutuality risks abdicating the practitioner's responsibilities as an expert, and they address that concern by recovering a nuanced but genuinely directive clinical role. Cribb and Entwistle helpfully categorize models of shared decision making as 'narrower' and 'broader' and praise the latter's 'open-ended and fully dialogical ways of relating'. However, they stop short of providing a philosophical account of how that dialogue works. In this paper, a nurse-midwife and a philosopher collaborate to argue that the Socratic model of dialogue offers a solution to the practitioner-patient dilemma. In the Theaetetus, Socrates compares dialogical reasoning to 'midwifery with all its standard features'. By means of a three-way analogy, elements of midwifery practice are used to illuminate features of Socrates' claim that his dialogue is like midwifery; those features are then translated into an approach to shared decision making as the 'midwifery of good thinking' which both midwives and physicians would do well to adopt. A key concept that emerges is the need for practitioners to make a risk-confidence assessment of the particular content of any decision to appropriately modulate their role in the practice of shared decision making.

Sound clinical judgment in nursing: A concept analysis

OBJECTIVE

The intent of this concept analysis is to offer a clear understanding of the definition, defining attributes, antecedents, and consequences of sound clinical judgment pertaining to nursing practice.

BACKGROUND

Sound clinical judgment is essential in nursing because decisions made influence patient outcomes.

DESIGN

This concept analysis guided by Walker and Avant's framework, dissects the concept to promote clarity and consensus.

DATA SOURCE

CINAHL, ProQuest for Nursing and Allied Health, ERIC, and Health Source/Nursing Academic Edition databases were searched using the keyword clinical judgment.

REVIEW METHODS

Articles in peer reviewed, scholarly journals written in English were considered from 1984 to 2017.

RESULTS

The author concluded that decision-making is a surrogate term for clinical judgment. The attributes, antecedents, and consequences are discussed and supported by evidence. Cases illustrate the essence of the concept.

CONCLUSIONS

Clinical judgment is an ambiguous term that is synonymous with the term decision-making. It results from critical thinking and clinical reasoning. Using these findings, educators and administrators can use valid and reliable methods to identify the presence, foster the development, and measure the existence of clinical judgment in novice nurses with an ultimate goal to improve patient care.

Use of clinical simulation to improve diagnostic reasoning in nursing

Abstract Objectives: Propose a methodology for the construction of simulated scenarios and cases to improve diagnostic reasoning in nursing. Method: A methodological study was conducted using theories and concepts from the dual processing theory to develop cases and scenarios of clinical simulation for diagnostic reasoning in nursing through proper use of analytical and non-analytical reasoning. Results and discussion: This study presents and discusses issues of the theoretical framework and operational elements: structure of scenarios, preparation of simulation, briefing, debriefing, and modeling, incorporating any required content. The methodology articulates content that is compatible with analytical reasoning, non-analytical studies and diagnostic accuracy measurements of clinical validation studies. Conclusion: This study demonstrated the feasibility of modeling simulated cases that combine dual processing with diagnostic reasoning in nursing. Implications: Contribution to learning in a safer simulated environment, adopting theoretical bases from studies on human reasoning.

Reconciling disparate data to determine the right answer: A grounded theory of meta analysts' reasoning in meta-analysis

While the systematic review process is intended to maximize objectivity and limit researchers' biases, examples remain of discordant recommendations from meta-analyses. Current guidelines to explore discrepancies assume the variation is produced by methodological differences and thus focus only on the study process. Because heterogeneity of interpretation also occurs when experts examine the same data, our purpose was to examine if there are reasoning differences, ie, in how information is processed and valued. We created simulated meta-analyses based on idealized randomized studies (ie, perfect studies with no bias) to ensure differences in interpretations could only be due to reasoning. We recruited published meta-analysts using purposeful variables. We conducted 3 audio-recorded interviews per participant using structured and semi-structured interviews, with paraphrasing and reflective listening to enhance and verify responses. Recruitment and analysis of transcripts and field notes followed the principles of grounded theory (eg, theoretical saturation, constant comparative analysis). Results show the complexity of meta-analytic reasoning. At each step of the process, participants attempted to reconcile disparate forms of knowledge to determine a right answer (moral concern) and accurately draw a treatment effect (epistemological concern). The reasoning processes often shifted between considering the meta-analysis as if the data were whole, and as if the data were discrete components (individual studies). These findings highlight paradigmatic tensions regarding the epistemological premises of meta-analysis, resembling previous historical investigations of the functioning of scientific communities. In understanding why different meta-analysts interpret data differently, it may be unrealistic to expect objective homogenous recommendations based on meta-analyses.

Decision Making in Nursing Practice: A Concept Analysis

PURPOSE

The study aims to gain an understanding of the concept of decision making as it relates to the nurse practice environment.

METHODS

Rodgers' evolutionary method on concept analysis was used as a framework for the study of the concept. Articles from 1952 to 2014 were reviewed from PsycINFO, Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), JSTOR, PubMed, and Science Direct.

FINDINGS

Findings suggest that decision making in the nurse practice environment is a complex process, integral to the nursing profession. The definition of decision making, and the attributes, antecedents, and consequences, are discussed. Contextual factors that influence the process are also discussed. An exemplar is presented to illustrate the concept.

CONCLUSION

Decision making in the nurse practice environment is a dynamic conceptual process that may affect patient outcomes. Nurses need to call upon ways of knowing to make sound decisions and should be self-reflective in order to develop the process further in the professional arena. The need for further research is discussed.

Differential Diagnosis: Correctly Putting the Pieces of the Puzzle Together

Each day, we generate hypotheses about our environment—our perceptions of people, our expectations of events, and our interpretation of images. These hypotheses provide a framework by which we interpret our experiences. The same is true for differential diagnosis by which health care practitioners develop hypotheses or diagnoses from a set of cues provided during an encounter with a patient. For clinicians to be successful at differential diagnosis, they must use a multidimensional and complex process involving nonanalytic and analytic cognitive processes and metacognition—thinking about thinking. Our conclusions, however, can lead to errors in diagnosis. Many of these errors are due to errors in cognition. The purpose of this article is to discuss this complex process, identify common errors in cognition, and offer strategies to prevent these common errors in differential diagnosis.

Enhancing clinical decision making: development of a contiguous definition and conceptual framework

Clinical decision making is a term frequently used to describe the fundamental role of the nurse practitioner; however, other terms have been used interchangeably. The purpose of this article is to begin the process of developing a definition and framework of clinical decision making. The developed definition was "Clinical decision making is a contextual, continuous, and evolving process, where data are gathered, interpreted, and evaluated in order to select an evidence-based choice of action." A contiguous framework for clinical decision making specific for nurse practitioners is also proposed. Having a clear and unique understanding of clinical decision making will allow for consistent use of the term, which is relevant given the changing educational requirements for nurse practitioners and broadening scope of practice.

Representing the nursing process with nursing terminologies in electronic medical record systems: a Swiss approach

This article describes a framework model within a selected nursing classification system for the integration of nursing care processes into a clinical information system. The "Electronic Nursing Process Data Model," project was carried out from July 2004 to October 2006 in the Canton of Zurich in Switzerland. The Zurich Electronic Nursing Process Data Model integrates the nursing diagnosis, outcomes, and intervention terminologies in a standardized manner into the nursing care process within the electronic patient record. Findings of the pretest application in clinical nursing practices revealed that (1) functionalities are logically structured, (2) it is difficult to overview many details of the documentation, (3) a specific "to-do list" retrieved from the electronic system is needed, and (4) free-text entries are important to add description of the patient's situation. Furthermore, a consistent assessment terminology needs to be linked to the nursing diagnosis, outcomes, and intervention terminologies and the descriptions of nursing care process within the Electronic Nursing Process Data Model. As the project team, we recommend to implement the developed Electronic Nursing Process Data Model into professional software of clinical information systems and gradually into clinical practice. Therefore, an appropriate utilization strategy includes issues to improve nurses' understanding of the nursing care process and critical-thinking skills: not even the most comprehensive software program can substitute for facilitation.

The interpretation of systematic reviews with meta-analyses: an objective or subjective process?

Background

Discrepancies between the conclusions of different meta-analyses (quantitative syntheses of systematic reviews) are often ascribed to methodological differences. The objective of this study was to determine the discordance in interpretations when meta-analysts are presented with identical data.

Methods

We searched the literature for all randomized clinical trials (RCT) and review articles on the efficacy of intravenous magnesium in the early post-myocardial infarction period. We organized the articles chronologically and grouped them in packages. The first package included the first RCT, and a summary of the review articles published prior to first RCT. The second package contained the second and third RCT, a meta-analysis based on the data, and a summary of all review articles published prior to the third RCT. Similar packages were created for the 5^th RCT, 10^th RCT, 20^th RCT and 23^rd RCT (all articles). We presented the packages one at a time to eight different reviewers and asked them to answer three clinical questions after each package based solely on the information provided. The clinical questions included whether 1) they believed magnesium is now proven beneficial, 2) they believed magnesium will eventually be proven to be beneficial, and 3) they would recommend its use at this time.

Results

There was considerable disagreement among the reviewers for each package, and for each question. The discrepancies increased when the heterogeneity of the data increased. In addition, some reviewers became more sceptical of the effectiveness of magnesium over time, and some reviewers became less sceptical.

Conclusion

The interpretation of the results of systematic reviews with meta-analyses includes a subjective component that can lead to discordant conclusions that are independent of the methodology used to obtain or analyse the data.

The evidence-based practice ideologies

This paper puts forward the argument that there are various, competing, and antithetical evidence-based practice (EBP) definitions and acknowledges that the different EBP definitions are based on different epistemological perspectives. However, this is not enough to understand the way in which nurse professionals choose between the various EBP formations and consequently facilitate them in choosing the most appropriate for their needs. Therefore, the current article goes beyond and behind the various EBP epistemologies to identify how individuals choose an epistemology, which consequently will assist our understanding as to how an individual chooses a specific EBP formation. Individuals choose an epistemology on the mere belief that the specific epistemology offers the ideals or ideas of best explaining or interpreting daily reality. These ideals or ideas are termed by science, history, and politics as ideology. Similarly, individual practitioners choose or should choose between the different EBP formations based on their own personal ideology. Consequently, this article proceeds to analyse the various ideologies behind different EBP definitions as to conclude that there are two broad ideologies that inform the various EBP formations, namely the ideology of truth and the ideology of individual emancipation. These two ideologies are analysed and their connections to the various EBP formations are depicted. Eventually, the article concludes that the in-depth, critical, and intentional analysis by individual nurses of their own ideology will allow them to choose the EBP formation that is most appropriate and fitting for them, and their specific situation. Hence, the conscious analysis of individual ideology becomes the criterion for choosing between competing EBP formations and allows for best evidence to be implemented in practice. Therefore, the best way to teach EBP courses is by facilitating students to analyse their own ideology.

A review of evidence-based practice, nursing research and reflection: levelling the hierarchy

AIM

This paper examines the evidence-based practice movement, the hierarchy of evidence and the relationship between evidence-based practice and reflective practice.

BACKGROUND

Evidence-based practice is equated with effective decision making, with avoidance of habitual practice and with enhanced clinical performance. The hierarchy of evidence has promoted randomized control trials as the most valid source of evidence. However, this is problematic for practitioners as randomized control trials overlook certain types of knowledge that, through the process of reflection, provide useful information for individualized and effective practice.

METHOD

A literature search was undertaken using CINAHL, medline and Ovid electronic databases in early 2006. The search terms used were: evidence-based practice, research evidence, evidence for practice, qualitative research, reflective practice, reflection and evidence. Other sources included handpicking of books on evidence-based practice, reflection and research. Only material written in English was included.

FINDINGS

The hierarchy of evidence that has promoted randomized control trials as the most valid form of evidence may actually impede the use of most effective treatment because of practical, political/ideological and epistemological contradictions and limitations. Furthermore, evidence-based practice appears to share very similar definitions, aims and procedures with reflective practice. Hence, it appears that the evidence-based practice movement may benefit much more from the use of reflection on practice, rather than the use of the hierarchical structure of evidence.

CONCLUSION

Evidence-based practice is necessary for nursing, but its' effective implementation may be hindered by the hierarchy of evidence. Furthermore, evidence-based practice and reflection are both processes that share very similar aims and procedures. Therefore, to enable the implementation of best evidence in practice, the hierarchy of evidence might need to be abandoned and reflection to become a core component of the evidence-based practice movement.

RELEVANCE TO CLINICAL PRACTICE

Provides an elaborated analysis for clinical nurses on the definition and implementation of evidence in practice.

Clinical cognition and biomedical informatics: issues of patient safety

Recent developments in biomedical informatics research have afforded possibilities for great advances in health care delivery. These exciting opportunities also present a number of challenges to the implementation and integration of technologies in the workplace. As in most domains, there is a gulf between technologic artifacts and end users, which compromises the culture of safety in the workplace. Because clinical practice is a human endeavor, there is a need for bridging disciplines to enable clinicians to benefit from rapid technologic advances. This, in turn, necessitates a broadening of disciplinary boundaries to consider cognitive and social factors related to the design and use of technology. The authors argue for a place of prominence for cognitive science in understanding nursing factors associated with patient safety. Cognitive science provides a framework for the analysis and modeling of complex human performance. Studies of clinical cognition can meaningfully inform and shape design, development and assessment of information systems. Furthermore, they have a decisive impact on whether information technology has a positive influence on human performance and are especially important in understanding and promoting safe practices. These issues are discussed in the context of clinical informatics with a focus on nursing practice.
