Achieving Quality in Clinical Decision Making: Cognitive Strategies and Detection of Bias

ACADEMIC EMERGENCY MEDICINE, Issue 11 2002
Pat Croskerry MD
Clinical decision making is a cornerstone of high-quality care in emergency medicine. The density of decision making is unusually high in this unique milieu, and a combination of strategies has necessarily evolved to manage the load. In addition to the traditional hypothetico-deductive method, emergency physicians use several other approaches, principal among which are heuristics. These cognitive short-cutting strategies are especially adaptive under the time and resource limitations that prevail in many emergency departments (EDs), but occasionally they fail. When they do, we refer to them as cognitive errors. They are costly but highly preventable. It is important that emergency physicians be aware of the nature and extent of these heuristics and biases, or cognitive dispositions to respond (CDRs). Thirty are catalogued in this article, together with descriptions of their properties as well as the impact they have on clinical decision making in the ED. Strategies are delineated in each case, to minimize their occurrence. Detection and recognition of these cognitive phenomena are a first step in achieving cognitive de-biasing to improve clinical decision making in the ED. [source]

THE SIGNAL DETECTION THEORY ROC CURVE: SOME APPLICATIONS IN FOOD SENSORY SCIENCE

JOURNAL OF SENSORY STUDIES, Issue 2 2008
M. O'MAHONY
ABSTRACT In psychology, the receiver operating characteristic (ROC) curve is a key part of Signal Detection Theory, which is used for calculating d, values in discrimination tests. In food sensory science, the ROC curve can also be a useful tool. To give a specific example, it is not always convenient to use forced-choice protocols for difference tests; foods may be fatiguing, and assessments with single presentations, like the Yes,No procedure, might be more appropriate. In this case, ROC curves provide a useful method for computing d, values. More generally, ROC curves give information about cognitive strategies. Cognitive strategies are important for difference tests. Values of d, can only be computed if the cognitive strategy used in the test is known. PRACTICAL APPLICATIONS When using methods other than two-alternative forced-choice in difference testing, a receiver operating characteristic (ROC) curve would be required to compute d,. This is because when assessing discrimination ability, the cognitive strategy of the subject must be taken into account, and ROC curves can sometimes reveal the cognitive strategy used by the subject. This article describes how the cognitive strategy can be determined from the subject's ROC curve. The hidden assumptions made when using ROC curves and how these assumptions can be tested are also given. This information is essential to researchers in sensory evaluation as well as those using these methods in a practical setting. [source]

Cognitive strategies and the resolution of acute stress disorder,

JOURNAL OF TRAUMATIC STRESS, Issue 1 2001
Richard A. Bryant
Abstract Information processing theories propose that resolution of posttraumatic stress is mediated by activation of traumatic memories and modification of threat-based beliefs. It is argued that this adaptive response is associated with reduced cognitive avoidance. Thought control strategies were assessed in civilian trauma survivors with acute stress disorder (N = 45) prior to and following either cognitive behavior therapy or supportive counseling. Participants completed the Acute Stress Disorder Interview, the Beck Depression Inventory, the State Trait Anxiety Inventory, the Impact of Event Scale, and the Thought Control Questionnaire within 2 weeks of their trauma and 6 months following treatment. Receiving cognitive behavior therapy was associated with reductions in the use of punishment and worry, and increases in the use of reappraisal and social control strategies. Further, reduced posttraumatic stress symptoms were associated with increased use of social control strategies and reappraisal strategies, and decreased use of worry. Findings are discussed in terms of the cognitive strategies that may mediate acute posttraumatic stress. [source]

Dissociable neural activity to self- vs. externally administered thermal hyperalgesia: a parametric fMRI study

EUROPEAN JOURNAL OF NEUROSCIENCE, Issue 3 2008
C. Mohr
Abstract Little is known regarding how cognitive strategies help to modulate neural responses of the human brain in ongoing pain syndromes to alleviate pain. Under pathological pain conditions, any self-elicited contact with usually non-painful stimuli may become painful. We examined whether the human brain is capable of dissociating self-controlled from externally administered thermal hyperalgesia in the experimental capsaicin model. Using functional magnetic resonance imaging, 17 male subjects were investigated in a parametric design with heat stimuli at topically capsaicin-sensitized skin. In contrast to external stimulation, self-administered pain was controllable. For both conditions application trials without noticeable thermal stimulation were introduced and used as high-level baseline (HLB) to account for the capsaicin-induced ongoing pain and other covariables. Following subtraction of the HLB, the anterior insula and the anterior cingulate cortex (ACC) but not the somatosensory cortices maintained parametric neural responses to thermal hyperalgesia. A stronger pain-related activity increase during self-administered stimuli was observed in the posterior insula. In contrast, prefrontal cortex showed stronger increases to uncontrollable external heat stimuli. In the state of ongoing pain (capsaicin), pain-intensity-encoding regions (anterior insula, ACC) but not those with sensory discriminative functions (SI, SII) showed graded, pain-intensity-related neural responses in thermal hyperalgesia. Some areas were able to dissociate between self- and externally administered stimuli in thermal hyperalgesia, which might be related to differences in perceived controllability. Thus, neural mechanisms maintain the ability to dissociate external from self-generated states of injury in thermal hyperalgesia. This may help to understand how cognitive strategies potentially alleviate chronic pain syndromes. [source]

The management of severe dental phobia in an adolescent boy: a case report

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 4 2000
J. Levitt
Dental fear is a widespread problem that represents one of the major barriers to dental care. This report describes a case study of a 12-year-old boy who presented with dental phobia characterized as ,fear of catastrophe', ,generalized dental fear' and ,fear of specific stimuli'. The referral came from his general dental practitioner who had been unable to carry out even the simplest dental procedure on him. The patient required prevention, conservation and root canal therapy. The case illustrates the use of physical strategies, including muscle relaxation and relaxation breathing; practice strategies, including graded exposure and cognitive strategies, combined with individual control methods and inhalation sedation to successfully complete the dental treatment plan.

Bayesian strategy assessment in multi-attribute decision making

JOURNAL OF BEHAVIORAL DECISION MAKING, Issue 3 2003
Arndt Bröder
Abstract Behavioral Decision Research on multi-attribute decision making is plagued with the problem of drawing inferences from behavioral data on cognitive strategies. This bridging problem has been tackled by a range of methodical approaches, namely Structural Modeling (SM), Process Tracing (PT), and comparative model fitting. Whereas SM and PT have been criticized for a number of reasons, the comparative fitting approach has some theoretical advantages as long as the formal relation between theories and data is specified. A Bayesian method is developed that is able to assess, whether an empirical data vector was most likely generated by a ,Take The Best' heuristic (Gigerenzer et al., 1991), by an equal weight rule, or a compensatory strategy. Equations are derived for the two- and three-alternative cases, respectively, and a simulation study supports its validity. The classification also showed convergent validity with Process Tracing measures in an experiment. Potential extensions of the general approach to other applications in behavioral decision research are discussed. Copyright © 2003 John Wiley & Sons, Ltd. [source]

A study of nurses' inferences of patients' physical pain

JOURNAL OF CLINICAL NURSING, Issue 4 2006
Benita Wilson BSc
Aim., The aim of this study was to establish if postregistration education and clinical experience influence nurses' inferences of patients' physical pain. Background., Pain is a complex, subjective phenomenon making it an experience that is elusive and difficult to define. Evaluation of an individual's pain is the product of a dynamic, interactive process that frequently results in ineffective pain management. Educating nurses should address the deficit, however the clinical environment is thought to be most influential in the acquisition of knowledge. Design., A series of vignettes was used to consider nurses' inferences of physical pain for six hypothetical patients; these were employed within a self-administered questionnaire that also addressed lifestyle factors of patients in pain, general attitudes and beliefs about pain management and general knowledge of pain control. Method., One hundred questionnaires were distributed; 86 nurses returned the questionnaire giving a response rate of 86%. Following selection of the sample 72 nurses participated in the study: 35 hospice/oncology nurses (specialist) and 37 district nurses (general). Data analysis was carried out using SPSS and qualitative analysis of the written responses. Results., The specialist nurses tended to infer lower levels of physical pain than the general nurses when considering the patients in the vignettes. Conclusion., Education and clinical experience influence nurses' knowledge, attitudes and beliefs about pain. However, it would appear that the specialist nurses' working environment and knowledge base engenders a practice theory divide, resulting in desensitization to patients' physical pain. Relevance to clinical practice., It is suggested that the specialist nurses use defence mechanisms to protect them from the conflict that arises from working within the clinical environment. These cognitive strategies have the potential to ease cognitive dissonance for the nurse, but may increase patient suffering. [source]

The cognitive nature of forgiveness: Using cognitive strategies of primary appraisal and coping to describe the process of forgiving

JOURNAL OF CLINICAL PSYCHOLOGY, Issue 6 2007
John Maltby
The present study investigated forgiveness in a traditional cognitive model of stress appraisal and coping and in a more recent model that includes the construct of low control stressors. One-hundred sixty six men and 168 women completed measures of forgiveness, primary stress appraisals, and coping strategies. For men, forgiveness was found to be positively associated with the use of challenge appraisals, and negatively associated with the use of loss appraisals and emotion-focused coping. For women, forgiveness was found to be positively associated with emotion-focused coping and acceptance, and negatively associated with avoidance. The results for women indicate that when forgiveness situations are conceptualized as low-control stressors, we are able to explain the relationships between forgiveness, appraisal, and coping. The results for men are broadly in line with a more traditional model of coping, which does not consider the construct of low control. Crucial differences in the ways that men and women appraise and cope with situations involving forgiveness are discussed. © 2007 Wiley Periodicals, Inc. J Clin Psychol. [source]

An exploration of students' strategy use in inquiry-based computer-supported collaborative learning

JOURNAL OF COMPUTER ASSISTED LEARNING, Issue 1 2005
Hanna Salovaara
Abstract The aim of this study is to investigate students' use of cognitive learning strategies in inquiry-based computer-supported collaborative learning (CSCL). A process-oriented interview framework on cognitive activity, self-regulation and motivation, and a coding category for analysing cognitive learning strategies and cognitive self-regulation was developed. The students of an intervention group (n=18) participating in inquiry-based CSCL and a comparison group (n=8) were interviewed six to eight times during the 3 years of the study. The results derived from the mixed-method analysis of altogether 161 interviews were compared between the two groups. The results indicate that the students who participated in the inquiry-based CSCL activities reported deeper-level cognitive strategies such as monitoring, creating representations and sharing information collaboratively. The students of the comparison group reported more surface-level strategies such as memorization. However, the findings concerning the utility of CSCL inquiry on cognitive learning strategies were not uniformly positive. It was found that the students of the comparison group reported significantly more strategies under the category of content evaluation. Nevertheless, the results suggest that computer-supported inquiry-based learning can enhance the use of cognitive strategies that support learning. [source]

THE SIGNAL DETECTION THEORY ROC CURVE: SOME APPLICATIONS IN FOOD SENSORY SCIENCE

The self-regulation of curiosity and interest during the information search process of adolescent students

JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 7 2010
Leanne Bowler
In a world of increasing information and communications possibilities, the difficulty for users of information systems and services may not lie in finding information but in filtering and integrating it into a cohesive whole. To do this, information seekers must know when and how to effectively use cognitive strategies to regulate their own thinking, motivation, and actions. Sometimes this is difficult when the topic is interesting and one is driven to explore it in great depth. This article reports on a qualitative study that, in the course of exploring the thinking and emotions of 10 adolescents during the information search process, uncovered patterns of behavior that are related to curiosity and interest. The larger purpose of the study was to investigate the metacognitive knowledge of adolescents, ages 16,18, as they searched for, selected, and used information to complete a school-based information task. The study found that the curiosity experienced by adolescents during the search process was accompanied by feelings of both pleasure and pain and that both feelings needed to be managed in order to navigate a pathway through the search process. The self-regulation of curiosity and interest was a clear and distinct metacognitive strategy fueled by metacognitive knowledge related to understanding one's own curiosity and the emotions attached to it.

Efficacy of Cognitive Nursing Intervention for Voice Hearing

PERSPECTIVES IN PSYCHIATRIC CARE, Issue 2 2007
Margaret England PhD
PROBLEM.,Many individuals who hear negative voices are troubled by their voices even when they adhere to prescribed neuroleptic medication regimens. At the same time, recent clinical trials provide evidence that structured, cognitive intervention can reduce distress tied to refractory auditory hallucinations and other psychiatric symptoms. PURPOSE.,The purpose of this randomized controlled trial was to determine whether usual care (UC), or usual care plus 12, 90-min episodes of cognitive nursing intervention (UC + CNI) led to sustained improvement in the psychiatric symptoms and self-esteem of 65 voice hearers assigned a diagnosis of schizophrenia or schizoaffective disorder. ANALYSIS AND FINDINGS.,Analysis of covariance with repeated measures procedures indicate that the 44 participants exposed to UC + CNI, were significantly more likely than the 21 participants exposed to UC only, to sustain significant improvement in psychiatric symptoms and self-esteem 1 year following treatment. IMPLICATIONS.,These findings provide encouragement for nurses to further develop and investigate cognitive strategies to treat psychiatric symptoms of voice hearers. [source]

Gender effects in spatial orientation: cognitive profiles and mental strategies

APPLIED COGNITIVE PSYCHOLOGY, Issue 5 2004
Andrea Bosco
Experimental evidence and meta-analyses offer some support for gender-related differences in visuo-spatial ability. However, few studies addressed this issue in an ecological context and/or in everyday tasks implying spatial abilities, such as geographical orientation. Moreover, the relation of specific strategies and gender is still unclear. In the present investigation, we compared men and women in a newly designed battery of spatial orientation tasks in which landmark, route and survey knowledge were considered. In addition, four visuo-spatial working memory (VSWM) tasks were presented. Significant differences favouring men in VSWM tasks were reported, supporting existing evidence. However, men and women did not significantly differ in orientation tasks performance. The patterns of correlation between working memory and spatial orientation tasks indicated that men and women used somewhat different strategies in carrying out the orientation tasks. In particular, active processes seem to play a greater role in females' performance, thus confirming the importance of this variable in interpreting gender effect in VSWM tasks. Altogether, results indicate that gender effects could well result from differences in cognitive strategies and support data indicating that adequate training could reduce or eliminate them.

Prevention of relapse and interventions for enhancing medication adherence in schizophrenia: An East Asian perspective

ASIA-PACIFIC PSYCHIATRY, Issue 2 2010
Salleh Mohd Razali MPM FAMM
Abstract Introduction: Studies investigating the efficacy of interventions for improving treatment non-adherence in schizophrenia have generated contrasting findings. The present review examined psychosocial interventions for improving medication adherence and prevention of relapse among patients with schizophrenia in developing countries in the Asia-Pacific. Methods: The relevant literature and systematic review were identified by computerized searches using keywords, and hand-searched for other selected articles. Results: The reasons for poor medication adherence were complex and heterogenous. Psychoeducation programs alone are ineffective in achieving good medication adherence because they do not lead to attitudinal and behavioral changes. The greatest improvement in adherence was seen with interventions employing a combination of educational, behavioral and cognitive strategies. Unfortunately, few relevant studies from this region were found. There were some interventions related to psychoeducation and compliance therapy (CT) that were successfully conducted by nurses. Patients in developing countries generally had better family support, but strong stigma towards mental illness and interference by traditional healers led to poor treatment adherence. Lack of facilities and shortage of medical professionals aggravated the situation. Discussion: Intervention to improve treatment adherence and prevention of relapse among patients with schizophrenia should be incorporated into existing psychiatric services. Adherence to treatment in patients with schizophrenia could be improved if continuously supported and monitored by caregivers and treating doctors, to facilitate a change in the patient's attitude. Paramedical personnel, such as psychiatric nurses, could be actively involved in intervention programs because of the shortage of medical professionals in this region. [source]

Cognitive strategy use by children with Asperger's syndrome during intervention for motor-based goals

AUSTRALIAN OCCUPATIONAL THERAPY JOURNAL, Issue 2 2009
Sylvia Rodger
Background:,Cognitive Orientation for (daily) Occupational Performance (CO-OP) is a cognitive approach utilised by occupational therapists to help guide children in the discovery of appropriate strategies for effective task performance through a structured problem-solving process. There has been limited research into its utility for children with Asperger's syndrome (AS). These children often present with motor difficulties, although these are not required for diagnosis of the syndrome. A recent study found that children with AS were able to use the CO-OP framework to enhance their performance of motor-based goals. Methods:,This paper presents two case studies demonstrating the use of CO-OP with children with AS, and explores the global and domain-specific strategies and types of guidance utilised to improve their task performance. Two children with AS, aged 9 and 11, with above average intellectual ability, engaged in 10 sessions of CO-OP. All sessions were videotaped. One hundred minutes of randomly selected footage were coded per child using the Observer Software Package version 5.0. Results:,The mean interrater agreement for the two children was 94.06% and 89.30%. Both children (i) utilised the global strategies ,do', followed by ,plan' and ,check', (ii) used at least three domain-specific strategies in each session with ,task specification/modification' and ,body position' utilised most, and (iii) used limited verbal self-guidance. Conclusion:,These two children with AS were able to utilise cognitive strategies to effectively solve their motor performance problems. Children with AS and those with DCD used similar strategies to achieve motor goals. CO-OP appears to have potential as an effective intervention for children with AS. Study limitations, clinical implications and directions for future research are discussed. [source]

Multiple Encounter Simulation for High-acuity Multipatient Environment Training

ACADEMIC EMERGENCY MEDICINE, Issue 12 2007
Leo Kobayashi MD
Patient safety interventions for multitasking, multipatient, error-prone work settings such as the emergency department (ED) must improve assorted clinical abilities, specific cognitive strategies, and teamwork functions of the staff to be effective. Multiple encounter simulation scenarios explore and convey this specialized mental work-set through use of multiple high-fidelity medical simulation (SIM) manikins in realistic surroundings. Multipatient scenarios reflect the work situations being targeted yet have the benefit of scripted control and instructor guidance to advance specific educational objectives. The use of two or more SIM patients promotes the exploration not only of multiple distinct clinical issues but also of interdependent processes pervasive in EDs. Cascading shortages of time, personnel, equipment, and supplies are re-created, thereby replicating process limitations at various levels, in a safe environment in which compensatory actions and adaptive behaviors can be learned. Distinguishing features of multipatient exercises include 1) broadened educational scope and expanded indications for SIM application, 2) enhanced scenario complexity, 3) controlled exposure to high workload environments, 4) expanded communication requirements, and 5) increased potential for reflective learning. Widespread and effective training in well-replicated, carefully coordinated representations of complex multipatient work environments may strengthen educational interventions for personnel working in high acuity and work-overloaded settings such as the ED. The use of concurrent patient encounter SIM exercises to elicit calculated stressors and to foster compensatory staff behaviors is an educational advance toward this objective. The authors present SIM methodology using concurrent patient encounters to replicate these environments. [source]

Reduced right hemisphere activation in severely abused violent offenders during a working memory task: An fMRI study

AGGRESSIVE BEHAVIOR, Issue 2 2001
Adrian Raine
Abstract This study uses functional magnetic resonance imaging (fMRI) to address two important gaps in our knowledge of brain functioning and violence: (1) What are the brain correlates of adults in the community who have suffered severe physical abuse early in life and who go on to perpetrate serious violence in adulthood? (2) What characterizes those who experience severe physical abuse but who refrain from serious violence? Four groups of participants recruited from the community (controls, severe physical child abuse only, serious violence only, and severely abused, seriously violent offenders) underwent fMRI while performing a visual/verbal working memory task. Violent offenders who had suffered severe child abuse show reduced right hemisphere functioning, particularly in the right temporal cortex. Abused individuals who refrain from serious violence showed relatively lower left, but higher right, activation of the superior temporal gyrus. Abused individuals, irrespective of violence status, showed reduced cortical activation during the working memory task, especially in the left hemisphere. Brain deficits were independent of IQ, history of head injury, task performance, cognitive strategy, and mental activity during the control task. Findings constitute the first fMRI study of brain dysfunction in violent offenders, and indicate that initial right hemisphere dysfunction, when combined with the effects of severe early physical abuse, predisposes to serious violence but that relatively good right hemisphere functioning protects against violence in physically abused children.
