Implementing high-value, cost-conscious care: experiences of Irish doctors and the role of education in facilitating this approach.

BACKGROUND: Adopting high-value, cost-conscious care (HVCCC) principles into medical education is growing in importance due to soaring global healthcare costs and the recognition that efficient care can enhance patient outcomes and control costs. Understanding the current opportunities and challenges doctors face concerning HVCCC in healthcare systems is crucial to tailor education to doctors' needs. Hence, this study aimed to explore medical students, junior doctors, and senior doctors' experiences with HVCCC, and to seek senior doctors' viewpoints on how education can foster HVCCC in clinical environments. METHODS: Using a mixed-methods design, our study involved a cross-sectional survey using the Maastricht HVCCC-Attitude Questionnaire (MHAQ), with a subset of consultants engaging in semi-structured interviews. Descriptive analysis provided insights into both categorical and non-categorical variables, with differences examined across roles (students, interns, junior doctors, senior doctors) via Kruskal-Wallis tests, supplemented by two-group analyses using Mann-Whitney U testing. We correlated experience with MHAQ scores using Spearman's rho, tested MHAQ's internal consistency with Cronbach's alpha, and employed thematic analysis for the qualitative data. RESULTS: We received 416 responses to the survey, and 12 senior doctors participated in the semi-structured interviews. Overall, all groups demonstrated moderately positive attitudes towards HVCCC, with more experienced doctors exhibiting more favourable views, especially about integrating costs into daily practice. In the interviews, participants agreed on the importance of instilling HVCCC values during undergraduate teaching and supplementing it with a formal curriculum in postgraduate training. This, coupled with practical knowledge gained on-the-job, was seen as a beneficial strategy for training doctors. CONCLUSIONS: This sample of medical students and hospital-based doctors display generally positive attitudes towards HVCCC, high-value care provision, and the integration of healthcare costs, suggesting receptiveness to future HVCCC training among students and doctors. Experience is a key factor in HVCCC, so early exposure to these concepts can potentially enhance practice within existing healthcare budgets.

Medical student empathy and breaking bad news communication in a simulated consultation.

OBJECTIVES: This study examined the relationship between self-reported empathy and breaking bad news (BBN) communication skills performance in a sample of undergraduate medical students (n = 100) in the clinical years of their program. METHODS: Correlational and regression analysis examined the relationship between Jefferson Scale of Physician Empathy (JSPE-S) and Empathy Quotient (EQ) scores, and communication skills performance based on students' application of the SPIKES protocol to a BBN scenario in a simulated encounter. RESULTS: Higher BBN communication skills performance was positively correlated with scores on the "Social Skills" EQ sub-scale (r (99) = 0.31, p = 0.002), which measures spontaneous and context-independent use of social skills. Multiple regression confirmed that "Social Skills" sub-scale variation predicted BBN score variation (B = 2.17, 95% CI = 0.65-3.69, p < 0.01). A weak positive association was also observed between BBN score and the "Standing in Patient's Shoes" JSPE sub-scale (r (99) = 0.22, p = 0.03). CONCLUSIONS: Findings suggest that specific aspects of dispositional empathy may moderate BBN communications skills competence in medical students. PRACTICE IMPLICATIONS: A better understanding of the moderating role of personality may lead to more tailored BBN communications skills training interventions and improved transfer of skills to workplace settings.

Association between dispositional empathy and self-other distinction in Irish and Belgian medical students: a cross-sectional analysis.

OBJECTIVE: Physicians' cognitive empathy is associated with improved diagnosis and better patient outcomes. The relationship between self-reported and performance-based measures of cognitive empathic processes is unclear. DESIGN: Cross-sectional analysis of the association between medical students' empathy scale scores and their empathic performance in a visuospatial perspective-taking (VPT) task. PARTICIPANTS: Undergraduate medical students across two European medical schools (n=194). PRIMARY AND SECONDARY OUTCOME MEASURES: Two self-report empathy and one performance-based perspective-taking outcome: Jefferson Scale of Physician Empathy (JSPE); Empathy Quotient (EQ); Samson's level-1 VPT task. RESULTS: Higher scores on the 'standing in patient's shoes' subscale of the JSPE were associated with a lower congruency effect (as well as lower egocentric and altercentric biases) in the VPT (B=-0.007, 95% CI=-0.013 to 0.002, p<0.05), which reflects an association with better capacity to manage conflicting self-other perspectives, also known as self-other distinction. Lower egocentric bias was also associated with higher scores on the 'social skills' EQ subscale (B=-10.17, 95% CI=-17.98 to 2.36, p<0.05). Additionally, selection of a 'technique-oriented' clinical specialty preference was associated with a higher self-perspective advantage in the VPT, reflecting greater attentional priority given to the self-perspective. CONCLUSIONS: We show that self-assessment scores are associated with selected performance-based indices of perspective taking, providing a more fine-grained analysis of the cognitive domain of empathy assessed in medical student empathy scales. This analysis allows us to generate new critical hypotheses about the reasons why only certain self-report empathy measures (or their subscales) are associated with physicians' observed empathic ability.

Investigating Potential Correlations between Endodontic Pathology and Cardiovascular Diseases Using Epidemiological and Genetic Approaches.

INTRODUCTION: Apical periodontitis (AP) and cardiovascular diseases (CVDs) are chronic conditions triggered by an inflammatory process and sharing similar pathogeneses and molecular players. Previous studies have suggested that AP may perpetuate a systemic inflammation state and, in turn, contribute to CVD. In this study, we investigated the potential association between endodontic pathology and CVD using epidemiological and genetic approaches. METHODS: Epidemiologic analysis was performed by querying the medical and dental records of >2 million patients. We retrieved information on positive/negative history for endodontic pathologies and CVDs using diagnostic and treatment codes from a dental school-based and a hospital-based patient electronic health record system. A case-control genetic association study was also performed; 10 single nucleotide polymorphisms in genes identified as strongly associated with CVDs were genotyped in 195 cases with AP and 189 control individuals without AP. Data analyses were performed using the chi-square and Fisher exact tests. P ≤.05 indicates significant difference between groups. RESULTS: Significant associations were found between the presence of endodontic pathology and a history of hypertension, myocardial infarction, cerebrovascular accident, pacemaker, congestive heart failure, heart block, deep vein thrombosis, and cardiac surgery (0.0001 ≤ P ≤ .008). A modest association was found for heart murmur and atrial fibrillation (P = .04). A trend toward positive association (P = .05) was also found between AP and a single nucleotide polymorphism in KCNK3, a gene known to be involved in increased susceptibility to hypertension. CONCLUSIONS: Significant associations were found between endodontic pathology and various CVDs and CVD-related risk factors, particularly hypertension. A trend toward a positive association was also found between AP and KCNK3, suggesting that common genetic variations may underlie different diseases. Additional studies with larger sample sizes have the potential to elucidate common mechanisms underlying AP and CVD.

Saving Natural Teeth: Intentional Replantation-Protocol and Case Series.

INTRODUCTION: Intentional replantation is a reliable and predictable treatment for cases in which nonsurgical endodontic retreatment failed or is impractical and endodontic surgery is hampered because of anatomic limitations. METHODS AND RESULTS: This article presents a protocol for intentional replantation illustrated with some interesting cases. The cases presented here are from patients (average age, 61 years) with no contributing medical history. The cases are molars with previous failed endodontic treatment/retreatment and diagnosed with apical periodontitis. Treatment procedures included atraumatic extractions with minimal manipulations of the periodontal ligament, followed by root-end resection, root-end preparation with ultrasonic tips, root-end fill with bioceramic cement, and rapid tooth replacement into the socket. Granulomatous tissue was gently curetted when applicable. All procedures were performed under the microscope. CONCLUSIONS: Intentional replantation with careful case selection may be considered as a last option for preserving hopeless teeth. Atraumatic extraction by using state-of-the-art equipment, instruments, and materials, minimal extra-alveolar time, and maintaining an aseptic technique are key factors for success.
