BACKGROUND: Unprofessional behaviour can interfere with patient care. Empowering trainees to address each other's unprofessional behaviour can help address a larger number of incidents that may not be witnessed by supervisors, as well as promote a culture of professionalism in a teaching programme. The goal of the study was to teach trainees to effectively address observed unprofessional behaviour and to assess the impact of this exercise on the percentage of cases directly addressed, reported or ignored 6-12 months after the initial training. METHODS: Eighty-four trainees participated in objective structured clinical examination (OSCE) cases designed to address a colleague's inappropriate behaviour. Baseline and follow-up surveys performed 6-12 months after the OSCE were completed detailing the number of incidents witnessed in colleagues and the method employed to address those incidents: personally address (with level of satisfaction), report or ignore. RESULTS: There was a significant increase in the number of unprofessional incidents identified after the OSCE (pre-OSCE, 1.12 per resident; post-OSCE, 1.69 per resident; t = 2.27, p = 0.029). Of the 72 incidents at baseline, 43 per cent were addressed directly and 43 per cent of those had a satisfactory resolution. Of the 71 incidents described 6-12 months later, 61 per cent were addressed directly and 79 per cent of those had a satisfactory resolution. Trainees were more likely to address rather than to report unprofessional behaviour chi2 (2, 58) = 13, p = 0.001. Empowering trainees to address each other's unprofessional behaviour can help promote a culture of professionalism DISCUSSION: The intervention had a significant impact on the percentage of trainees that addressed any observed unprofessional behaviour, and the rate of satisfaction after doing so. It did not change the percentage of cases that were neither addressed nor reported.

Symptomatic bradycardia due to gastric distension is a rarely reported entity in the field of medicine. The mechanism of gastrointestinal distention that contributes to bradycardia is complex. A 75-year-old female with recurrent episodes of dizziness in the setting of gastric distension was found to have severe sinus bradycardia which resolved upon resolution of gastric distension. No structural or functional abnormality of heart was found. The patient was treated with permanent pacemaker implantation due to recurrent episodes of dizziness in the setting of sinus bradycardia.

OBJECTIVE:To describe typologies of dyadic communication exchanges between primary care providers and their hypertensive patients about prescribed antihypertensive medications. METHODS:Qualitative analysis of 94 audiotaped patient-provider encounters, using grounded theory methodology. RESULTS:Four types of dyadic exchanges were identified: Interactive (53% of interactions), divergent-traditional (24% of interactions), convergent-traditional (17% of interactions) and disconnected (6% of interactions). In the interactive and convergent-traditional types, providers adopted a patient-centered approach and used communication behaviors to engage patients in the relationship. Patients in these interactions adopted either an active role in the visit (interactive), or a passive role (convergent-traditional). The divergent-traditional type was characterized by provider verbal dominance, which inhibited patients' ability to ask questions, seek information, or check understanding of information. In the disconnected types, providers used mainly closed-ended questions and terse directives to gather and convey information, which was often disregarded by patients who instead diverted the conversation to psychosocial issues. CONCLUSIONS:This study identified interdependent patient-provider communication styles that can either facilitate or hinder discussions about prescribed medications. PRACTICE IMPLICATIONS/CONCLUSIONS:Examining the processes that underlie dyadic communication in patient-provider interactions is an essential first step to developing interventions that can improve the patient-provider relationship and patient health behaviors.

Background Little is known about the association of healthcare costs with damage accrual in SLE. We describe the costsassociated with damage progression using multi-statemodeling.Methods Patients fulfilling the revised ACR Classification Criteria for SLE from 32 centres in 11 countries were enrolledin the Systemic Lupus International Collaborating Clinics(SLICC) inception cohort within 15 months of diagnosis.Annual data on demographics, SLE disease activity (SLEDAI-2K), damage (SLICC/ACR Damage Index [SDI] if-6 monthsfrom diagnosis), hospitalizations, medications, dialysis, and utilization of selected medical/surgical procedures were collected.Annual health resource utilization was costed using 2017Canadian prices. Annual costs associated with SDI states wereobtained from multiple regressions adjusting for age, sex, race/ethnicity, and disease duration. As there were relatively fewtransitions to SDI states 5 11, these were merged into a singleSDI state. Five and 10 year cumulative costs were estimatedby multiplying annual costs associated with each SDI state bythe expected duration in each state, which was forecastedusing a multi-state model and longitudinal SDI data from theSLICC Inception Cohort (Bruce IN et al. Ann Rheum Dis2015;74:1706 13). Future costs were discounted at a yearlyrate of 3%.Results 1676 patients participated, 88.7% female, 49.2% Caucasian, mean age at diagnosis 34.6 years (SD 13.4), mean disease duration at enrollment 0.5 years (range 0 1.3 years), andmean follow up 7.8 years (range 0.6 16.9 years). Healthresource utilization and annual costs (after adjustment usingregression) were markedly higher in those with higher SDIs(SDI=0, annual costs $1847, 95% CI $1120 to $2574;SDI-5, annual costs $26 772, 95% CI $19 631 to $33 813).At SDI<=2, hospitalizations and medications accounted for97.1% of direct costs, whereas at SDI-3, dialysis was responsible for 55.0%.Five and 10 year cumulative costs stratified by baseline SDIwere calculated by multiplying the annual costs associatedwith each SDI by the expected duration in that state. Fiveand 10 year costs were greater in those with the highest SDIsat baseline (table 1).Conclusions Patients with the highest baseline SDIs incurannual costs and 10 year cumulative costs that are at least 10-fold higher than those with the lowest baseline SDI. By estimating the expected duration in each SDI state and incorporating annual costs, disease severity at presentation can beused to predict future healthcare costs, critical knowledge forcost-effectiveness evaluations of novel therapies

Background There are no longitudinal studies regarding thelong term cardiac health of children with cardiac manifestations of neonatal lupus (NL). This study was performed toevaluate risk factors for morbidity and provide evidence-basedguidance regarding the course of cardiac NL.Methods Echocardiograms throughout life were evaluated in240 individuals born with cardiac NL from the ResearchRegistry for Neonatal Lupus: 142 were available from ages 0 1 years, 174 from ages 1 17 years, and 65>17 years. A composite adverse outcome defined as qualitatively decreased leftventricular (LV) function or concurrent use of cardiac medications was assessed. Aortic dilation (root or ascendingaorta z-score >2.0) was also recorded. Analyses were performed to associate the composite adverse outcome and aorticdilation with maternal medications, pacing, and fetal diseasestatus, including a severity score based on mortality risk factors such as lower fetal heart rate and extranodal disease.Results The composite adverse outcome for cardiac dysfunctionwas identified in 21.1% of echos in children ages 0 1, 13.2% ages1 17% and 29.2% ages>17. In 89 children in which echos wereavailable at ages 0 1 and 1 17, 6/16 with dysfunction at ages 0 1were also affected at ages 1 17, while 10 reverted to normal.Among those without dysfunction at age 0 1, 8/90 developednew worsening of cardiac function during age 1 17. In 35 caseswith echos at ages 1 17 and >17, 3/3 cases with dysfunction atage 1 17 were also affected at >17, and 2/32 developed new dysfunction in adulthood. Cardiac dysfunction was significantly associated with number of years paced at all ages (p<0.001, 0.001,<0.001). A lower fetal ventricular heart rate at the first time ofheart block detection was associated with cardiac dysfunction age0 1 and >17 (p=0.048, 0.005 respectively) and lowest heart ratein utero associated with dysfunction at age <1 and 1 17(p<0.001, 0.015). Fetal extranodal cardiac disease was associatedwith dysfunction in ages1 17 and >17 (p=0.026, 0.023). Higherfetal severity score associated with postnatal dysfunction in ages0 1 and 1 17 groups (p=0.013, 0.001). Aortic dilation waspresent in 13.4% at ages 0 1% and 14.9% at ages 1 17, butat >17, dilation only occurred in 9.2%. There was no associationof postnatal cardiac dysfunction or aortic dilation with maternalmedication use, maternal rheumatic disease, fetal age at heartblock detection or gestational age of birth.Conclusions Cardiac dysfunction in the first year normalizesby later childhood in the majority of cases, possibly due tothe short term effects of cardiac pacing or resolution ofinflammation with the clearance of maternal autoantibodies.However, new onset dysfunction can occur after the first yearof life. Aortic dilation can continue for longer periods, butmay decrease in frequency with age. Nevertheless, cardiac dysfunction is present in roughly 30%, and in adulthood thereare associations with fetal extranodal disease and heart rate atdetection. Patients who develop morbidity in utero may havesubclinical damage or be more susceptible to future insultsthat manifest later in life, which can be exacerbated by prolonged pacing. Close monitoring and aggressive treatment ofearly extranodal disease in cardiac NL may have long termbenefit in preventing subsequent morbidity

Medication literacy is the ability of individuals to access and understand medication information and then use that information to act and take their medication in a safe and appropriate way. The purpose of this study was to explore medication literacy in a group of Somali older adults and their families using qualitative secondary analysis. We conducted an analytic expansion of an existing qualitative study that explored the home healthcare perceptions of Somali older adults and their families. Qualitative data collected from 14 Somali families about home healthcare were reviewed and analyzed for material related to medication literacy. Data analysis revealed a number of important findings related to medication literacy and resulted in the discovery of four themes: Medication literacy is needed among Somali older adults and their families, Using home healthcare (HHC) to improve medication literacy, Better communication is essential to improving medication literacy, and Medication literacy is an intersecting family and social issue. The results of this study indicate that HHC has a role to play in improving the health and medication literacy of these families. They also highlight the need to further explore what techniques, tools, and/or supports HHC professionals need to care for non-English speaking populations. Future research needs to address how to meet the needs of diverse and vulnerable patients like Somali older adults, and how best to prepare HHC providers to do this.
