Gut feelings as a third track in general practitioners' diagnostic reasoning

BackgroundGeneral practitioners (GPs) are often faced with complicated, vague problems in situations of uncertainty that they have to solve at short notice. In such situations, gut feelings seem to play a substantial role in their diagnostic process. Qualitative research distinguished a sense of alarm and a sense of reassurance. However, not every GP trusted their gut feelings, since a scientific explanation is lacking.ObjectiveThis paper explains how gut feelings arise and function in GPs’ diagnostic reasoning.ApproachThe paper reviews literature from medical, psychological and neuroscientific perspectives.ConclusionsGut feelings in general practice are based on the interaction between patient information and a GP’s knowledge and experience. This is visualized in a knowledge-based model of GPs’ diagnostic reasoning emphasizing that this complex task combines analytical and non-analytical cognitive processes. The model integrates the two well-known diagnostic reasoning tracks of medical decision-making and medical problem-solving, and adds gut feelings as a third track. Analytical and non-analytical diagnostic reasoning interacts continuously, and GPs use elements of all three tracks, depending on the task and the situation. In this dual process theory, gut feelings emerge as a consequence of non-analytical processing of the available information and knowledge, either reassuring GPs or alerting them that something is wrong and action is required. The role of affect as a heuristic within the physician’s knowledge network explains how gut feelings may help GPs to navigate in a mostly efficient way in the often complex and uncertain diagnostic situations of general practice. Emotion research and neuroscientific data support the unmistakable role of affect in the process of making decisions and explain the bodily sensation of gut feelings.The implications for health care practice and medical education are discussed.

Can medical schools rely on clerkships to train students in basic clinical skills

 Many medical schools have drawn up lists of basic clinical skills that students are required to have mastered at the end of medical training. To determine whether undergraduate students actually perform these basic clinical skills during clerkships and whether different approaches to skills training led to different results, we surveyed 365 final‐year medical students in 1996 and 1997.

An evaluation study of the didactic quality of clerkships

Previous qualitative research at the University of Antwerp revealed dissatisfaction amongst medical students about clinical clerkships.

Family physicians' diagnostic gut feelings are measurable: construct validation of a questionnaire

BackgroundFamily physicians perceive that gut feelings, i.e. a ‘sense of reassurance’ or a ‘sense of alarm’, play a substantial role in diagnostic reasoning. A measuring instrument is desirable for further research. Our objective is to validate a questionnaire measuring the presence of gut feelings in diagnostic reasoning.MethodsWe constructed 16 case vignettes from real practice situations and used the accompanying ‘sense of reassurance’ or the ‘sense of alarm’ as reference labels. Based on the results of an initial study (26 family physicians), we divided the case vignettes into a group involving a clear role for the sense of reassurance or the sense of alarm and a group involving an ambiguous role. 49 experienced family physicians evaluated each 10 vignettes using the questionnaire. Construct validity was assessed by testing hypotheses and an internal consistency procedure was performed.ResultsAs hypothesized we found that the correlations between the reference labels and corresponding items were high for the clear-case vignettes (0.59 – 0.72) and low for the ambiguous-case vignettes (0.08 – 0.23). The agreement between the classification in clear sense of reassurance, clear sense of alarm and ambiguous case vignettes as derived from the initial study and the study population’s judgments was substantial (Kappa = 0.62). Factor analysis showed one factor with opposites for sense of reassurance and sense of alarm items. The questionnaire’s internal consistency was high (0.91). We provided a linguistic validated English-language text of the questionnaire.ConclusionsThe questionnaire appears to be valid. It enables quantitative research into the role of gut feelings and their diagnostic value in family physicians’ diagnostic reasoning.

Effectiveness of basic clinical skills training programmes: a cross-sectional comparison of four medical schools

Training in physical diagnostic skills is an important part of undergraduate medical education. The objective of this study was to study the outcome of skills training at four medical schools.

The diagnostic role of gut feelings in general practice A focus group study of the concept and its determinants

BackgroundGeneral practitioners sometimes base clinical decisions on gut feelings alone, even though there is little evidence of their diagnostic and prognostic value in daily practice. Research into these aspects and the use of the concept in medical education require a practical and valid description of gut feelings. The goal of our study was therefore to describe the concept of gut feelings in general practice and to identify their main determinantsMethodsQualitative research including 4 focus group discussions. A heterogeneous sample of 28 GPs. Text analysis of the focus group discussions, using a grounded theory approach.ResultsGut feelings are familiar to most GPs in the Netherlands and play a substantial role in their everyday routine. The participants distinguished two types of gut feelings, a sense of reassurance and a sense of alarm. In the former case, a GP is sure about prognosis and therapy, although they may not always have a clear diagnosis in mind. A sense of alarm means that a GP has the feeling that something is wrong even though objective arguments are lacking. GPs in the focus groups experienced gut feelings as a compass in situations of uncertainty and the majority of GPs trusted this guide. We identified the main determinants of gut feelings: fitting, alerting and interfering factors, sensation, contextual knowledge, medical education, experience and personality.ConclusionThe role of gut feelings in general practice has become much clearer, but we need more research into the contributions of individual determinants and into the test properties of gut feelings to make the concept suitable for medical education.

Obstacles to adherence in living with type-2 diabetes: An international qualitative study using meta-ethnography (EUROBSTACLE)

Quantitative studies failed to determine variables which consistently explain adherence or non-adherence to treatment recommendations. Qualitative studies identified issues such as the quality of the health provider-health receiver relationship and the patients health beliefs. According to these findings, 39 focus groups of 246 people living with type-2 diabetes were conducted in seven European countries, assessing health beliefs, communication with caregivers and problems encountered in adhering to treatment regimens. Meta-ethnography was later applied to make a qualitative meta-analysis. Obstacles to adherence are common across countries, and seem to be related less to issues of the health-care system and more to patients knowledge about diabetes, beliefs and attitudes and the relationship with health-care professionals. The resulting key themes are course of diabetes, information, person and context, body awareness and relationship with the health care provider. Meta-ethnography is a feasible tool for the meta-analysis of multilingual qualitative data and leads to a richer account.

Impact of euthanasia on primary care physicians in the Netherlands.

Background : There is only limited knowledge about the emotional impact that performing euthanasia has on primary care physicians (PCPs) in the Netherlands. Objective : To obtain more insight into the emotional impact on PCPs of performing euthanasia or assisted suicide, and to tailor the educational needs of vocational PCP trainees accordingly. Methods : Qualitative research, consisting of four focus group studies. The setting was primary care in the Netherlands; 22 PCPs participated, in four groups (older males, older females, younger males and a group with interest with regard to euthanasia). Results : Various phases with different emotions were distinguished: before (tension), during (loss) and after (relief) the event. Although it is a very rare occurrence, euthanasia has a major impact on PCPs. Their relationship with the patient, their loneliness, the role of the family, and pressure from society are the main issues that emerged. Making sufficient emotional space and time available to take leave adequately from a patient is important for PCPs. Conclusions : Many PCPs stressed that young physicians should form their own opinions about euthanasia and other end-of-life decisions early on in their career. We recommend that these issues are officially included in the vocational training programme for general practice. Palliative Medicine 2007; 21 : 609—614

Efficacy of daily intake of Lactobacillus casei Shirota on respiratory symptoms and influenza vaccination immune response: a randomized, double-blind, placebo-controlled trial in healthy elderly nursing home residents

BACKGROUND Age is associated with immune dysregulation, which results in an increased infection rate and reduced effectiveness of vaccination. OBJECTIVE We assessed whether an intervention with Lactobacillus casei Shirota (LcS) in elderly nursing home residents reduced their susceptibility to respiratory symptoms and improved their immune response to influenza vaccination. DESIGN Between October 2007 and April 2008, a randomized, double-blind, placebo-controlled trial was conducted in 737 healthy people aged ≥ 65 y in 53 nursing homes in Antwerp, Belgium. Volunteers were randomly assigned to receive a probiotic (n = 375; 2 bottles of fermented milk that contained ≥ 6.5 × 10(9) live LcS/bottle) or a placebo (n = 362; similar drink with no bacteria) for 176 d. After 21 d, all subjects received an influenza vaccination. Primary outcome parameters were the number of days with respiratory symptoms, the probability of respiratory symptoms, and antiinfluenza antibody titer by hemagglutination inhibition after vaccination. RESULTS Univariate and multivariate modeling showed no effect of the probiotic on clinical outcome parameters. Generalized linear mixed modeling showed no effect of the probiotic itself on the probability of respiratory symptoms [OR of probiotic: 0.8715; 95% CI: 0.6168, 1.2887). No significant difference regarding the influenza-vaccination immune response was shown. CONCLUSION The results of this study show that daily consumption of a fermented milk drink that contains LcS has no statistically or clinically significant effect on the protection against respiratory symptoms. This trial was registered at clinicaltrials.gov as NCT00849277.
