The Impact of Simulated Medical Consultations on the Empathy Levels of Students at One Medical School

Purpose To examine the impact of simulated medical consultations using standardized patients (SPs) on the empathy levels of fourth- and sixth-year students at the Unicamp medical school in Brazil. Method Throughout 2011 and 2012, the authors conducted this study with two classes of fourth-year (n = 124) and two classes of sixth-year (n = 123) medical students. Students completed the medical student version of the Jefferson Scale of Physician Empathy before and after simulated medical consultations with SPs, followed by an in-depth debriefing dealing with the feelings of the patient about the disease, such as fear, guilt, anger, and abandonment; the feelings of the doctor towards the patient; and other topics as they arose. Results The simulation activity increased the empathy scores of the fourth-year students (from 115.8 to 121.1, P < .001, effect size = 0.61) and of the sixth-year students (from 117.1 to 123.5, P < .001, effect size = 0.64). Conclusions Although the study results were obtained via self-report—a limitation—they suggest that the effective simulation of medical consultations with SPs may improve medical students’ empathy levels. One unexpected result was that this activity, during the debriefing, became a forum for debating topics such as the doctor–patient relationship, the hidden curriculum, negative role models, and emotionally significant experiences of students in medical school. This kind of activity in itself may influence young doctors to become more empathetic and compassionate with their patients and foster a more meaningful way of practicing medicine.

Measuring medical students' empathy: exploring the underlying constructs of and associations between two widely used self-report instruments in five countries

Purpose Understanding medical student empathy is important to future patient care; however, the definition and development of clinical empathy remain unclear. The authors sought to examine the underlying constructs of two of the most widely used self-report instruments—Davis’s Interpersonal Reactivity Index (IRI) and the Jefferson Scale of Empathy version for medical students (JSE-S)—plus, the distinctions and associations between these instruments. Method Between 2007 and 2014, the authors administered the IRI and JSE-S in three separate studies in five countries, (Brazil, Ireland, New Zealand, Portugal, and the United Kingdom). They collected data from 3,069 undergraduate medical students and performed exploratory factor analyses, correlation analyses, and multiple linear regression analyses. Results Exploratory factor analysis yielded identical results in each country, confirming the subscale structures of each instrument. Results of correlation analyses indicated significant but weak correlations (r = 0.313) between the total IRI and JSE-S scores. All intercorrelations of IRI and JSE-S subscale scores were statistically significant but weak (range r = −0.040 to 0.306). Multiple linear regression models revealed that the IRI subscales were weak predictors of all JSE-S subscale and total scores. The IRI subscales explained between 9.0% and 15.3% of variance for JSE-S subscales and 19.5% for JSE-S total score. Conclusions The IRI and JSE-S are only weakly related, suggesting that they may measure different constructs. To better understand this distinction, more studies using both instruments and involving students at different stages in their medical education, as well as more longitudinal and qualitative studies, are needed.

A simplified ultrasound-based edema score to assess lung injury and clinical severity in septic patients

BACKGROUND Lung ultrasound (US) is an excellent tool to assess lung edema in a myriad of different clinical situations. We hypothesized that lung US might also be a good prognostic and management instrument in septic patients, regardless of disease severity. METHODS This was a prospective observational cohort study at an urban academic emergency department (ED). Inclusion criteria were as follows: septic patients, at least 18 years old, admitted at the ED of a tertiary hospital. A simplified lung edema scoring system (SLESS) was developed, and 6 thoracic regions were evaluated. Four different lung US patterns were considered, from normal aeration to total consolidation. To evaluate disease severity, the SLESS was compared with the Mortality in Emergency Department Sepsis Score and the third version of the Simplified Acute Physiology Score scoring systems. Aiming to assess the effect of the lung edema in the gas exchange, the SLESS was compared with the Pao2/fraction of inspired oxygen ratio. RESULTS Sixty-one patients were enrolled in a 3-month period. The SLESS had a good correlation with the Mortality in Emergency Department Sepsis Score and Simplified Acute Physiology Score (r = 0.53 and r = 0.55, respectively; P < .001 for both) and a negative correlation with the Pao2/fraction of inspired oxygen ratio (r = -0.62; P < .001). The SLESS also showed correlation with the respiratory rate (r = 0.45; P = .0003). The odds ratio for death related to the SLESS was 1.370 (95% confidence interval, 1.109-1.691; P = .0035). CONCLUSION The SLESS is an easy and practical scoring system. It might be a useful tool to predict severity of disease in sepsis patients. The SLESS might also be able to be correlated with the oxygen exchange.

Cognitive Load and Self-Determination Theories Applied to E-Learning: Impact on Students' Participation and Academic Performance

Background Emergency clerkships expose students to a stressful environment that require multiple tasks, which may have a direct impact on cognitive load and motivation for learning. To address this challenge, Cognitive Load Theory and Self Determination Theory provided the conceptual frameworks to the development of a Moodle-based online Emergency Medicine course, inspired by real clinical cases. Methods Three consecutive classes (2013–2015) of sixth-year medical students (n = 304) participated in the course, during a curricular and essentially practical emergency rotation. “Virtual Rounds” provided weekly virtual patients in narrative format and meaningful schemata to chief complaints, in order to simulate real rounds at Emergency Unit. Additional activities such as Extreme Decisions, Emergency Quiz and Electrocardiographic challenge offered different views of emergency care. Authors assessed student´s participation and its correlation with their academic performance. A survey evaluated students´ opinions. Students graduating in 2015 answered an online questionnaire to investigate cognitive load and motivation. Results Each student produced 1965 pageviews and spent 72 hours logged on. Although Clinical Emergency rotation has two months long, students accessed the online course during an average of 5.3 months. Virtual Rounds was the most accessed activity, and there was positive correlations between the number of hours logged on the platform and final grades on Emergency Medicine. Over 90% of students felt an improvement in their clinical reasoning and considered themselves better prepared for rendering Emergency care. Considering a Likert scale from 1 (minimum load) to 7 (maximum load), the scores for total cognitive load were 4.79±2.2 for Virtual Rounds and 5.56±1.96 for real medical rounds(p<0,01). Conclusions A real-world inspired online course, based on cognitive and motivational conceptual frameworks, seems to be a strong tool to engage students in learning. It may support them to manage the cognitive challenges involved in clinical care and increase their motivation for learning.

Atipia de células glandulares em esfregaços do colo do útero: avaliação dos métodos propedêuticos

PURPOSE: to evaluate the diagnostic procedures used in women with Pap smear result of atypical glandular cells. PATIENTS AND METHODS: a prospective study with 159 women with atypical glandular cells was carried out between January and December 2000. All women were submitted to a new colpocytology and to colposcopy. Directed biopsy was performed in 50 cases, endocervical curettage in 21 and conization in 75. The performance of the diagnostic procedures was described by estimating the sensitivity, specificity, predictive values and likelihood ratio, considering histological results as gold standard. RESULTS: the histological evaluation showed 51 intraepithelial squamous lesions, 29 low grade and 22 high grade. Five women presented in situ adenocarcinoma and six patients presented invasive neoplasias. Colpocytology alone showed sensitivity and specificity of 88.5 and 39%, respectively, and colposcopy alone, 74 and 42%. The association of colpocytology with colposcopy increased the sensitivity to 98.4%, with a significantly lower specificity of 10%. Endocervical curettage showed low sensitivity (25%). CONCLUSION: the presence of atypical glandular cells on colpocytology was associated with preinvasive and invasive cervical lesions in 62.2% of the cases with histological evaluation. Repeating colpocytology and performing colposcopy allowed to select the women who needed histological evaluation. Conization was an adequate procedure when examination continued to show morphologic alterations.

Insuficiência respiratória aguda como manifestação da síndrome de eosinofilia-mialgia associada à ingestão de L-triptofano

Eosinophilia-myalgia syndrome was described in 1989 in patients who presented progressive and incapacitating myalgia and eosinophilia in blood, fluids and secretions. Most patients report previous L-tryptophan intake. Respiratory manifestations are found in up to 80% of the cases, occasionally as the only manifestation. Treatment includes drug discontinuation and administration of corticosteroids. Here, we describe the case of a 61-year-old female admitted with acute respiratory failure after using L-tryptophan, hydroxytryptophan and other drugs. The patient presented eosinophilia, together with elevated eosinophil counts in the bronchoalveolar lavage and pleural effusion. After discontinuation of the drugs previously used, corticosteroids were administered, resulting in clinical and radiological improvement within just a few days.Eosinophilia-myalgia syndrome was described in 1989 in patients who presented progressive and incapacitating myalgia and eosinophilia in blood, fluids and secretions.

Nurturing virtues of the medical profession: does it enhance medical students' empathy?

Objectives To examine if the empathy levels of first-year medical students are amenable to didactic interventions idealized to promote values inherent to medical professional identity. Methods This is a pretest-posttest study designed to assess the empathy levels of first-year medical students (n=166) comprising two consecutive classes of a Brazilian medical school, performed before and after a didactic intervention. Students attended a course based on values and virtues related to medical professional identity once a week over four months. Every didactic approach (interviews with patients and physicians, supervised visits to the hospital, and discussion of videotaped simulated consultations) was based on “real-world” situations and designed to promote awareness of the process of socialization. Students filled out the Jefferson Scale of Physician Empathy (JSPE) on the first and last days of this course, and the pretest-posttest analysis was performed using the Wilcoxon Signed Rank Test. Results The mean pretest JSPE score was 117.9 (minimum 92, maximum 135) and increased to 121.3 after the intervention (minimum 101, maximum 137). The difference was significant (z=-5.2, p<.001.), with an effect size of 0.40. The observed increase was greater among students with lower initial JSPE scores. Conclusions Empathy is a fundamental tool used to achieve a successful physician-patient relationship, and it seems to permeate other virtues of a good physician. This study’s results suggest that medical students’ empathy may be amenable to early curricular interventions designed to promote a positive development of their professional identity, even when empathy is not central in discussion.
