Barriers and facilitators to transition from pediatric to adult healthcare for immigrant youth with chronic health conditions.

PURPOSE: The objective of this study was to investigate the experience of first- and second- generation immigrant youth living with chronic health conditions in Canada, their parents or caregivers, and healthcare and service providers who care for immigrant youth, regarding the transition from pediatric to adult healthcare. DESIGN AND METHODS: We conducted semi-structured individual interviews and focus groups. Youth were 1st or 2nd generation immigrants, aged 16-25, with pediatric-onset chronic health conditions. Parents or caregivers had raised youth children as described. Providers delivered healthcare or other services to immigrant populations. Thematic analysis was conducted of all transcripts. RESULTS: Twenty youth, 14 parents/caregivers and five service providers participated. Most participants described healthcare transition as very difficult to navigate. Two major themes emerged across participant narratives: 1. Barriers to transition: lack of family experience in Canada, language, discrimination, financial strain, stigma, and long wait times. Some of these barriers are specific to newcomer families, but others are generalizable to the Canadian population. 2. Facilitators of transition: youth independence, youth acting as cultural bridges within their families, and cross-sector support between healthcare, education, social work and settlement services. CONCLUSIONS: Immigrant youth and their families face a broad range of barriers to healthcare transition. The collaborative nature of cross-sector support effectively addressed some of the barriers faced by newcomer families. PRACTICE IMPLICATIONS: Clinicians should provide immigrant youth and their families with accessible information about the health condition and how to navigate the adult healthcare system prior to transition, particularly when language barriers exist.

Acute kidney injury and renal recovery following Fontan surgery.

Objectives: Acute kidney injury has been described after Fontan surgery, but the duration and outcomes are unknown. We sought to describe the incidence of and risk factors for acute kidney injury and the phenotype of renal recovery, and evaluate the impact of renal recovery phenotype on outcomes. Methods: All children who underwent a Fontan operation at a single center between 2009 and 2022 were included. Data collected included Fontan characteristics, vasopressor use, all measures of creatinine, and postoperative outcomes. Logistic regression models were used to assess predictors of acute kidney injury and the association between acute kidney injury and outcomes. Results: We enrolled 141 children (45% female). Acute kidney injury occurred in 100 patients (71%). Acute kidney injury duration was transient (<48 hours) in 77 patients (55%), persistent (2-7 days) in 15 patients (11%), more than 7 days in 4 patients (3%), and unknown in 4 patients (3%). Risk factors for acute kidney injury included higher preoperative indexed pulmonary vascular resistance (odds ratio, 3.90; P = .004) and higher postoperative inotrope score on day 0 (odds ratio, 1.13, P = .047). Risk factors for acute kidney injury duration more than 48 hours included absence of a fenestration (odds ratio, 3.43, P = .03) and longer duration of cardiopulmonary bypass (odds ratio, 1.22 per 15-minute interval, P = .01). Acute kidney injury duration more than 48 hours was associated with longer length of stay compared with transient acute kidney injury (median 18 days [interquartile range, 9-62] vs 10 days [interquartile range, 8-16], P = .006) and more sternal wound infections (17% vs 4%, P = .049). Conclusions: Acute kidney injury after the Fontan operation is common. The occurrence and duration of acute kidney injury have significant implications for postoperative outcomes.

Patient factors and geographic barriers influencing excess time between paediatric and adult CHD care.

INTRODUCTION: Over 90% of children with CHD survive into adulthood and require lifelong cardiology care. Delays in care predispose patients to cardiac complications. We sought to determine the time interval to accessing adult CHD care beyond what was recommended by the referring paediatric cardiologist (excess time) and determine risk factors for prolonged excess time. MATERIALS AND METHODS: Retrospective cohort study including all patients in the province of Alberta, Canada, age 16-18 years at their last paediatric cardiology visit, with moderate or complex lesions. Excess time between paediatric and adult care was defined as the interval (months) between the final paediatric visit and the first adult visit, minus the recommended interval between these appointments. Patients whose first adult CHD appointment occurred earlier than the recommended interval were assigned an excess time of zero. RESULTS: We included 286 patients (66% male, mean age 17.6 years). Mean excess time was 7.9 ± 15.9 months. Twenty-nine (10%) had an excess time > 24 months. Not having a pacemaker (p = 0.03) and not needing cardiac medications at transfer (p = 0.02) were risk factors for excess time >3 months. Excess time was not influenced by CHD complexity. DISCUSSION: The mean delay to first adult CHD appointment was almost 8 months longer than recommended by referring paediatric cardiologists. Not having a pacemaker and not needing cardiac medication(s) were risk factors for excess time > 3 months. Greater outpatient resources are required to accommodate the growing number of adult CHD survivors.

Leadership Book Club: An Innovative Strategy to Incorporate Leadership Development Into Pharmacy Residency Programs.

Purpose: To describe an innovative strategy for incorporating leadership training and development across multiple postgraduate year 2 (PGY2) pharmacy residency programs at a single institution. Background: Tampa General Hospital has 7 pharmacy residency positions: 4 postgraduate year 1 (PGY1) residents and a single resident for each of the 3 PGY2 programs (critical care, emergency medicine, and solid organ transplant). Administrative topics are incorporated across the PGY1 and PGY2 residency programs, with each PGY2 program having additional administrative topics specific to their specialty area. Summary: What began as an elective administrative topic discussion for the PGY2 emergency medicine resident has evolved over time into a longitudinal leadership book club. The leadership book club is utilized to meet the residency goals and objectives related to leadership development for all 3 PGY2 programs. Each year a single book is identified through the American Society of Health-System Pharmacists (ASHP) Leadership Academy book list or by participant suggestion. The book is then divided into 4 sections with corresponding hour-long discussions that occur quarterly throughout the residency year. The residency program directors (RPDs) and co-RPDs lead the initial discussion, and each PGY2 resident leads 1 of the subsequent 3 discussions. Based on resident feedback, the leadership book club is an innovative and effective strategy to incorporate leadership training and development into residency training. Conclusion: It is imperative to foster the development of leadership skills in pharmacy residency programs to prevent a future leadership gap in health system pharmacy. Leadership book club is a unique strategy to incorporate leadership training longitudinally across multiple PGY2 residency programs at a single institution.

Expanding the reach of the Quitline by engaging volunteers to market it in hospitals and shopping venues - a pilot study.

BACKGROUND: In Canada, although there are periodic media campaigns to raise awareness of Quitlines, these services are underused. We sought to determine if a dedicated kiosk, similar to that used in the retail industry but staffed by volunteers trained in smoking cessation techniques, would be effective method to enhance Quitline reach. METHODS: We located a kiosk in the foyer of two hospitals and in two shopping malls in Edmonton, Canada between Feb/2012 and July/2014. The cessation intervention was based on the 5 A's approach. Outcome was assessed by number of visits to the kiosk and referral rates to the Quitline. A cross sectional survey among small sample of visitors was used for evaluation. Descriptive statistics were used to summarize visitors' data. RESULTS: Of 1091 kiosk visitors, 53.3 % were current smokers, of whom 93.3 % indicated a willingness to quit. Of these, 32.1 % requested a Quitline referral at the time of the kiosk visit. Referral requests to the Quitline were greater when the kiosk was located in the non-hospital setting 39.1 % compared to 31.1 % in hospitals (P = 0.2). Referrals from the kiosk represented 6 % of total referrals received by the provincial Quitline during the study period. Following referral the Quitline was able to reach 50 % of those referred, of those, 17 % refused to proceed. At seven month follow up 30 day abstinence rate was 3.8 % of smokers who wished quit. Visitors agreed that the kiosk design was interesting (89.3 %) and increased their knowledge about tobacco and cessation options (88.8 %) and encouraged them to take action to quit (85.7 %). CONCLUSIONS: A "volunteer manned kiosk" can increase awareness of smoking cessation resources in the community and increase referral rates to Quitline services.

'Herbal' but potentially hazardous: an analysis of the constituents and smoke emissions of tobacco-free waterpipe products and the air quality in the cafés where they are served.

BACKGROUND: There are limited data on the composition and smoke emissions of 'herbal' shisha products and the air quality of establishments where they are smoked. METHODS: Three studies of 'herbal' shisha were conducted: (1) samples of 'herbal' shisha products were chemically analysed; (2) 'herbal' and tobacco shisha were burned in a waterpipe smoking machine and main and sidestream smoke analysed by standard methods and (3) the air quality of six waterpipe cafés was assessed by measurement of CO, particulate and nicotine vapour content. RESULTS: We found considerable variation in heavy metal content between the three products sampled, one being particularly high in lead, chromium, nickel and arsenic. A similar pattern emerged for polycyclic aromatic hydrocarbons. Smoke emission analyses indicated that toxic byproducts produced by the combustion of 'herbal' shisha were equivalent or greater than those produced by tobacco shisha. The results of our air quality assessment demonstrated that mean PM2.5 levels and CO content were significantly higher in waterpipe establishments compared to a casino where cigarette smoking was permitted. Nicotine vapour was detected in one of the waterpipe cafés. CONCLUSIONS: 'Herbal' shisha products tested contained toxic trace metals and PAHs levels equivalent to, or in excess of, that found in cigarettes. Their mainstream and sidestream smoke emissions contained carcinogens equivalent to, or in excess of, those of tobacco products. The content of the air in the waterpipe cafés tested was potentially hazardous. These data, in aggregate, suggest that smoking 'herbal' shisha may well be dangerous to health.

Subject-specific estimation of central aortic blood pressure via system identification: preliminary in-human experimental study.

This paper demonstrates preliminary in-human validity of a novel subject-specific approach to estimation of central aortic blood pressure (CABP) from peripheral circulatory waveforms. In this "Individualized Transfer Function" (ITF) approach, CABP is estimated in two steps. First, the circulatory dynamics of the cardiovascular system are determined via model-based system identification, in which an arterial tree model is characterized based on the circulatory waveform signals measured at the body's extremity locations. Second, CABP waveform is estimated by de-convolving peripheral circulatory waveforms from the arterial tree model. The validity of the ITF approach was demonstrated using experimental data collected from 13 cardiac surgery patients. Compared with the invasive peripheral blood pressure (BP) measurements, the ITF approach yielded significant reduction in errors associated with the estimation of CABP, including 1.9-2.6 mmHg (34-42 %) reduction in BP waveform errors (p < 0.05) as well as 5.8-9.1 mmHg (67-76 %) and 6.0-9.7 mmHg (78-85 %) reductions in systolic and pulse pressure (SP and PP) errors (p < 0.05). It also showed modest but significant improvement over the generalized transfer function approach, including 0.1 mmHg (2.6 %) reduction in BP waveform errors as well as 0.7 (20 %) and 5.0 mmHg (75 %) reductions in SP and PP errors (p < 0.05).

Comparative study on tube-load modeling of arterial hemodynamics in humans.

In this paper, we assess the validity of two alternative tube-load models for describing the relationship between central aortic and peripheral arterial blood pressure (BP) waveforms in humans. In particular, a single-tube (1-TL) model and a serially connected two-tube (2-TL) model, both terminated with a Windkessel load, are considered as candidate representations of central aortic-peripheral arterial path. Using the central aortic, radial and femoral BP waveform data collected from eight human subjects undergoing coronary artery bypass graft with cardiopulmonary bypass procedure, the fidelity of the tube-load models was quantified and compared with each other. Both models could fit the central aortic-radial and central aortic-femoral BP waveform pairs effectively. Specifically, the models could estimate pulse travel time (PTT) accurately, and the model-derived frequency response was also close to the empirical transfer function estimate obtained directly from the central aortic and peripheral BP waveform data. However, 2-TL model was consistently superior to 1-TL model with statistical significance as far as the accuracy of the central aortic BP waveform was concerned. Indeed, the average waveform RMSE was 2.52 mmHg versus 3.24 mmHg for 2-TL and 1-TL models, respectively (p < 0.05); the r² value between measured and estimated central aortic BP waveforms was 0.96 and 0.93 for 2-TL and 1-TL models, respectively (p < 0.05). We concluded that the tube-load models considered in this paper are valid representations that can accurately reproduce central aortic-radial/femoral BP waveform relationships in humans, although the 2-TL model is preferred if an accurate central aortic BP waveform is highly desired.

Future physicians and tobacco: an online survey of the habits, beliefs and knowledge base of medical students at a Canadian University.

BACKGROUND: Little is known about the knowledge and attitudes towards tobacco use among medical students in Canada. Our objectives were to estimate the prevalence of tobacco use among medical students, assess their perceived level of education about tobacco addiction management and their preparedness to address tobacco use with their future patients. METHODS: A cross-sectional online survey was administered to University of Alberta undergraduate medical school trainees. The 32-question survey addressed student demographics, tobacco use, knowledge and attitudes around tobacco and waterpipe smoking, tobacco education received in medical school, as well as knowledge and competency regarding tobacco cessation interventions. RESULTS: Of 681 polled students, 301 completed the survey. Current (defined as "use within the last 30 days") cigarette, cigar/cigarillo and waterpipe smoking prevalence was 3.3%, 6% and 6%, respectively. One third of the respondents had ever smoked a cigarette, but 41% had tried cigars/cigarillos and 40% had smoked a waterpipe at some time in the past. Students reported moderate levels of education on a variety of tobacco-related subjects but were well-informed on the role of tobacco in disease causation. The majority of students in their final two years of training felt competent to provide tobacco cessation interventions, but only 10% definitively agreed that they had received enough training in this area. CONCLUSIONS: Waterpipe exposure/current use was surprisingly high among this sample of medical students, a population well educated about the role of tobacco in disease causation. The majority of respondents appeared to be adequately prepared to manage tobacco addiction but education could be improved, particularly training in behavioral modification techniques used in tobacco use cessation.
