Background: There are limited data on the association of material deprivation with clinical care and outcomes after atrial fibrillation (AF) diagnosis in jurisdictions with universal health care. Methods: This was a population-based cohort study of individuals ≥66 years of age with first diagnosis of AF between April 1, 2007, and March 31, 2019, in the Canadian province of Ontario, which provides public funding and prohibits private payment for medically necessary physician and hospital services. Prescription medications are subsidized for residents >65 years of age. The primary exposure was neighborhood material deprivation, a metric derived from Canadian census data to estimate inability to attain basic material needs. Neighborhoods were categorized by quintile from Q1 (least deprived) to Q5 (most deprived). Cause-specific hazards regression was used to study the association of material deprivation quintile with time to AF-related adverse events (death or hospitalization for stroke, heart failure, or bleeding), clinical services (physician visits, cardiac diagnostics), and interventions (anticoagulation, cardioversion, ablation) while adjusting for individual characteristics and regional cardiologist supply. Results: Among 347 632 individuals with AF (median age 79 years, 48.9% female), individuals in the most deprived neighborhoods (Q5) had higher prevalence of cardiovascular disease, risk factors, and noncardiovascular comorbidity relative to residents of the least deprived neighborhoods (Q1). After adjustment, Q5 residents had higher hazards of death (hazard ratio [HR], 1.16 [95% CI, 1.13–1.20]) and hospitalization for stroke (HR, 1.16 [95% CI, 1.07–1.27]), heart failure (HR, 1.14 [95% CI, 1.11–1.18]), or bleeding (HR, 1.16 [95% CI, 1.07–1.25]) relative to Q1. There were small differences across quintiles in primary care physician visits (HR, Q5 versus Q1, 0.91 [95% CI, 0.89–0.92]), echocardiography (HR, Q5 versus Q1, 0.97 [95% CI, 0.96–0.99]), and dispensation of anticoagulation (HR, Q5 versus Q1, 0.97 [95% CI, 0.95–0.98]). There were more prominent disparities for Q5 versus Q1 in cardiologist visits (HR, 0.84 [95% CI, 0.82–0.86]), cardioversion (HR, 0.80 [95% CI, 0.76–0.84]), and ablation (HR, 0.45 [95% CI, 0.30–0.67]). Conclusions: Despite universal health care and prescription medication coverage, residents of more deprived neighborhoods were less likely to visit cardiologists or receive rhythm control interventions after AF diagnosis, even though they exhibited higher cardiovascular disease burden and higher risk of adverse outcomes.

Background: Although cardiac rehabilitation (CR) has proven to have short- and mid-term benefit in treatment of coronary artery disease, its long-term benefit in patients who have undergone coronary artery bypass grafting (CABG) is less certain. Our objective was to examine the late outcomes of patients who attended CR within the first year after CABG. Methods: Adult CABG patients referred to Toronto Rehabilitation Institute (CR group: were referred and attended at least 1 session; No-CR group: were referred but did not attend) between January 1996 and September 2008 were identified through linkages with clinical and provincial administrative databases for comorbidities and outcome ascertainment. The primary outcome was a composite of all-cause mortality, acute myocardial infarction, stroke or repeat revascularization (major adverse cardiac and cerebrovascular events [MACCE]). The secondary outcome was all-cause mortality. Multivariable Cox proportional hazard models were used to assess the CR treatment effect, adjusting for baseline characteristics. Results: The study cohort consisted of 5,000 patients—3,685 (73.7%) in the CR group and 1,315 (26.3%) in the No-CR group. Median referral time was 32.5 days, and follow-up was 13.1 years. The CR group patients, compared with the No-CR group, were younger (age 62.6 ± 9.6 vs 64.0 ± 10.5 years), were more likely to be male (85.0% vs 79.5%), and had fewer cardiac comorbidities. In adjusted analyses, the CR group was associated with decreased MACCE (hazard ratio 0.83, 95% confidence interval 0.75-0.91, P < 0.0001) and a higher adjusted survival at 15 years (66.3% vs 60.1%, hazard ratio 0.76, 95% confidence interval 0.68-0.84, P < 0.0001), as compared with the No-CR group. Conclusions: There was a reduction in MACCE and late mortality associated with CR attendance, highlighting the importance of patient referral and participation in CR after CABG. Résumé: Contexte: La réadaptation cardiaque (RC) s’est révélée bénéfique à court et à moyen terme dans le traitement des coronaropathies, mais on en sait moins sur ses bienfaits à long terme chez les patients ayant subi un pontage aortocoronarien (PAC). Nous avons donc examiné les issues à long terme chez des patients ayant participé à un programme de RC dans l’année suivant un PAC. Méthodologie: À partir des données couplées des bases de données des cliniques et de l’administration provinciale, nous avons relevé tous les patients adultes ayant subi un PAC qui ont été orientés vers l’Institut de réadaptation de Toronto (groupe RC : patients orientés vers le programme et ayant participé à au moins 1 séance; groupe sans RC : patients orientés vers le programme, mais n’ayant participé à aucune séance) entre janvier 1996 et septembre 2008, afin d’établir les affections concomitantes et les résultats obtenus. Le critère d’évaluation principal composé comprenait la mortalité toutes causes confondues, l’infarctus du myocarde aigu, l’accident vasculaire cérébral (AVC) ou une nouvelle revascularisation en raison d’un événement cardiaque ou cérébrovasculaire majeur (ECCVM). Le critère d’évaluation secondaire était la mortalité toutes causes confondues. Nous avons utilisé des modèles à risques proportionnels de Cox multivariés pour évaluer l’effet thérapeutique de la RC, en apportant les corrections nécessaires pour tenir compte des caractéristiques initiales des patients. Résultats: La cohorte de l’étude réunissait 5 000 patients – 3 685 (73,7 %) dans le groupe RC et 1 315 (26,3 %) dans le groupe sans RC. Les valeurs médianes du temps écoulé avant l’orientation vers un programme de RC et de la période du suivi étaient de 32,5 jours et de 13,1 ans, respectivement. Comparativement aux patients du groupe sans RC, les patients du groupe RC étaient plus jeunes (62,6 ± 9,6 ans vs 64,0 ± 10,5 ans), étaient dans une plus forte proportion des hommes (85,0 % vs 79,5 %) et présentaient un moins grand nombre d’affections cardiaques concomitantes. À l’issue des analyses après corrections, on a observé dans le groupe RC une réduction du taux d’ECCVM (rapport des risques instantanés de 0,83; intervalle de confiance [IC] à 95 %, de 0,75 à 0,91; p < 0,0001) et une augmentation du taux de survie à 15 ans corrigé (66,3 % vs 60,1 %; rapport des risques instantanés de 0,76; IC à 95 %, de 0,68 à 0,84; p < 0,0001), comparativement au groupe sans RC. Conclusions: La participation à un programme de RC a été associée à une diminution du risque d’ECCVM et de mortalité tardive, ce qui fait ressortir l’importance d’orienter les patients ayant subi un PAC vers de tels programmes et de les encourager à y participer.

Background Though clinical guidelines for cholesterol-lowering therapies advocate for both a trial of lifestyle modification and the initiation of statin medication when appropriate, the extent to which lifestyle modification may alter a patient’s knowledge-perceptions and receptivity towards statins remains unclear. Methods Following completion of a 6-month comprehensive lifestyle modification program, perceived changes in knowledge and receptivity towards statins were examined across prespecified subgroups of age, sex, and statin eligibility using a mixed-methods questionnaire. Quantitative and qualitative analyses incorporated binomial tests, McNemar’s test, and thematic analyses. Results Among 192 patients who completed the program and exit questionnaire between December 15, 2020 and July 2, 2021, 88.4% of patients indicated a perceived improvement in cholesterol and/or statin knowledge (P < . 0001). 48.2% of patients acknowledged that their receptivity towards taking statins increased (P = . 61). Changes in receptivity were attributed to several identified program themes including improvements in health knowledge and awareness, motivation and empowerment. Patients who noted improvements in their mental health also reported significantly increased receptivity towards statins (P < . 001). Conclusions Patients’ perceived knowledge and receptivity towards statins may improve following participation in a comprehensive therapeutic lifestyle modification program. Future research must evaluate the impact of these programs on statin uptake, compliance and outcomes.

Background There are limited data on the association of poverty with outcomes and care patterns after an atrial fibrillation (AF) diagnosis in jurisdictions with universal healthcare. The Canadian province of Ontario provides publicly funded healthcare and prohibits private payment for medically necessary physician and in-hospital care. It also covers prescription medications for residents aged >65 years. Purpose Determine the association of neighbourhood-level poverty with outcomes and processes of care after AF diagnosis in older people within a universal healthcare system. Methods Using linked administrative databases, we conducted a population-based cohort study of community-dwelling adults aged ≥66 years who were newly diagnosed with AF in Ontario between April 1, 2007 and March 31, 2019. The primary exposure was material deprivation of patients' neighborhood of residence. This metric is derived using Canadian census data to estimate inability to access and attain basic material needs. Neighborhoods were categorized by quintile of material deprivation from Q1 (wealthiest) to Q5 (poorest). We used cause-specific hazards regression models to study the association of deprivation quintile with time to the following outcomes over one year from AF diagnosis: death, ischemic stroke, bleeding, heart failure (HF) hospitalization, cardiology services, and AF-specific treatments. Models accounted for clustering by region of residence and adjusted for age, sex, diabetes, HF, stroke/transient ischemic attack, vascular disease, hypertension, bleeding history, rural residence, renal function, and setting of AF diagnosis (hospital, emergency department [ED] or outpatient). Results We studied 350,353 patients with AF (median age 78 years, 48.9% female). People from neighborhoods in higher deprivation quintiles (poorer) were more likely to be diagnosed in hospital/ED than outpatient settings. Relative to people from the wealthiest neighbourhoods (Q1), patients in the poorest neighbourhoods (Q5) had higher prevalence of baseline hypertension, diabetes, HF, vascular disease and other comorbidities. In adjusted analyses (Figure), higher quintiles of neighborhood poverty were associated with greater rates of death, ischemic stroke, bleeding, and HF hospitalization, but lower rates of cardiology visits, cardiac testing, anticoagulation, anti-arrhythmic medications, cardioversion, or AF ablation. Conclusions In a setting of universal healthcare and prescription medication coverage, people living in poorer neighbourhoods had worse baseline health and higher rates of adverse outcomes after an AF diagnosis. Despite this, people in poorer neighbourhoods had less cardiology visits and diagnostic tests and were less likely to receive anticoagulation and rhythm control interventions. This shows that universal healthcare and medication coverage are insufficient to achieve equitable health care and outcomes for people with AF.

Glucose-6-phosphate dehydrogenase (G6PD) activity is used in the evaluation of hemolysis risk in patients being assessed for G6PD deficiency. A long-acting 8-aminoquinoline drug (tafenoquine) used in malaria treatment is contraindicated in patients with G6PD deficiency (70% normal G6PD activity). The current state of G6PD reporting practices to support clinical eligibility assessment is poorly understood.To assess clinical laboratory reporting practices for G6PD testing.In October 2019 and October 2020, voluntary questionnaires were distributed to 327 and 324 laboratories participating in the College of American Pathologists G6PD proficiency testing (PT).Two hundred fifty-seven and 119 laboratories responded to the 2019 and 2020 questionnaires, respectively. Few laboratories have received clinical questions about average normal G6PD activity (US/Canada, 2.0% [3 of 149]; international, 8.4% [9 of 107]), whereas slightly more have determined the average normal G6PD activity for their own assay and patient populations (US/Canada, 6.7% [10 of 149]; international, 19.4% [21 of 108]). Few laboratories report G6PD activity in percent of normal format (US/Canada, 2.7% [4 of 149]; international, 8.3% [9 of 108]). The most common unit of measurement in use for quantitative G6PD reporting is unit per gram of hemoglobin. Reference intervals vary based on assay, reaction temperature, and participant laboratory and demonstrate moderate correlation (r = .46-.51) to G6PD activity measured from a "normal" PT challenge specimen. Nearly half of participants (47.8% [85 of 178]) categorized a quantitatively "intermediate" G6PD PT challenge as "normal" when using qualitative assays.Percent of normal G6PD activity reporting would facilitate patient eligibility assessment for drugs, such as tafenoquine. Quantitative assays are better able to differentiate "intermediate" specimens than qualitative assays.

Objectives Prolonged sedentary time is recognized as a distinct health risk, and mortality risks are expected to be greatest for individuals with low exercise levels. It is unknown whether participation in exercise-based cardiac rehabilitation (CR) programs influences sedentary behaviour particularly among those patients expected to be at greatest mortality risk. This study examined the influence of CR participation on sedentary behaviour and identified the proportion and characteristics (socio-demographic and clinical) of patients who do not meet exercise recommendations and have prolonged sedentary times. Methods A prospective study was conducted among patients of an exercise-based CR program and assessments performed at baseline and 3 months. Physical activity and sedentary behaviour information were collected by self-report, and convergent validity was examined on an accelerometer-wearing subsample. Results Of 468 CR patients approached, 130 participants were recruited with an average sedentary time of 8 hours/day. Sedentary behaviour remained consistent at follow-up (relative change= −2.4%, P = 0.07) notwithstanding a greater proportion meeting exercise recommendations (relative change= 57.4%). 19.2% of participants were classified to have prolonged sedentary time and not meet exercise recommendations at baseline. No significant differences were found between the characteristics of high-risk individuals and lower risk subgroups. Findings were consistent among the accelerometer-derived subgroup and the overall sample despite poor to moderate convergent validity. Conclusions These results suggest that the exercise-focus of CR may not reduce sedentary behaviours. Future studies are needed to determine whether sedentary behaviour-specific reduction strategies are more effective than traditional exercise-based strategies and lead to meaningful improvements in clinical outcomes.

Although the burden of aortic stenosis (AS) on our health care system is expected to rise, little is known regarding its epidemiology at the population level. Our primary objective was to evaluate trends in AS hospitalization, treatment and outcomes.We performed a population-based observational study including 37,970 patients newly hospitalized with AS from 2004 and 2013 in Ontario, Canada. We calculated age- and sex-standardized rate of AS hospitalization through direct standardization. The independent association between year of the hospitalization, and 30-day and 1-year mortality rate was evaluated using logistic regression models to account for temporal changes in patient characteristics.The overall age- and sex-standardized AS hospitalization rate increased slightly from 36 per 100,000 in 2004 to 39 per 100,000 in 2013. A substantial increase was seen in patients ≥85years, where hospitalization rates increased 29% from 400 to 516 per 100,000 from 2004 to 2013 (P.001). In this study period, 36.2% of patients received aortic valve interventions within 30days of hospitalization. Among treated patients, an improving mortality trend was observed in which the adjusted odds ratio (OR) was significantly lower in 2013 as compared to 2004 (OR 0.55 for 30-day mortality, 0.74 for 1-year morality). In contrast, no significant temporal change in mortality was seen among patients without aortic valve intervention.AS hospitalizations in the elderly increased significantly beyond that was expected from population growth. Many AS patients did not receive aortic valve intervention after hospitalization. Mortality among the treated patients improved significantly over time.

Background: Stroke is associated with muscle atrophy and weakness, mobility deficits, and cardiorespiratory deconditioning. Aerobic and resistance training (AT and RT) each have the potential to improve deficits, yet there is limited evidence on the utility of combined training. Objective: To examine the effects of AT+RT versus AT on physiological outcomes in chronic stroke with motor impairments. Methods: Participants (n = 73) were randomized to 6 months of AT (5 d/wk) or AT+RT (3 and 2 d/wk, respectively). Outcomes included those related to body composition by dual-energy X-ray absorptiometry, mobility (6-minute walk distance [6MWD], sit-to-stand, and stair climb performance), cardiorespiratory fitness (VO2peak, oxygen uptake at the ventilatory threshold [VO2VT]), and muscular strength. Results: A total of 68 (93.2%) participants (age, mean ± SD = 63.7 ± 11.9) completed the study. AT+RT and AT yielded similar and significant improvements in 6MWD (39.9 ± 55.6 vs 36.5 ± 63.7 m, P = .8), VO2peak (16.4% ± 43.8% vs 15.2% ± 24.7%, P = .9), sit-to-stand time (−2.3 ± 5.1 vs 1.02 ± 9.5 s, P = .05), and stair climb performance (8.2% ± 19.6% vs 7.5% ± 23%, P = .97), respectively. AT+RT produced greater improvements than AT alone for total body lean mass (1.23 ± 2.3 vs 0.27 ± 1.6 kg, P = .039), predominantly trunk ( P = .02) and affected-side limbs ( P = .04), VO2VT (19.1% ± 26.8% vs 10.5% ± 28.9%, P = .046), and upper- and lower-limb muscular strength ( P < .03, all except affected-side leg). Conclusion: Despite being prescribed 40% less AT, AT+RT resulted in similar and significant improvement in mobility and VO2peak, superior improvements in VO2VT and muscular strength, and an almost 5-fold greater increase in lean mass compared with AT. RT is the most neglected exercise component following stroke but should be prescribed with AT for metabolic, cardiorespiratory, and strength recovery.

Background Medical diagnostic procedures, such as cardiac catheterization, can cause significant patient anxiety. Patient anxiety can have negative implications for compliance with healthcare visits, medical tests, and treatments. Music interventions may have a role in reducing anxiety related to cardiac catheterization procedures. Objective To perform a comprehensive systematic review and meta-analysis evaluating whether musical interventions reduce anxiety in patients undergoing cardiac catheterization. Data sources MEDLINE, EMBASE, CENTRAL, AMED, and PsychINFO from inception to May 2015. Reference lists of included articles were further hand searched for additional eligible studies. Study selection Randomized controlled trials evaluating the effectiveness of music interventions for anxiety reduction in patients undergoing cardiac catheterization. Data extraction and synthesis Data on trial design, baseline characteristics and outcomes was extracted using a data extraction table. Study quality and risk of bias were assessed using the JADAD scale. Main outcomes and measures The main outcome was the effectiveness of music interventions in reducing anxiety in this patient population. Meta-analysis was pursued using data from studies that had used the Spielberger state anxiety inventory (STAI-S) to measure anxiety reduction. Other outcomes qualitatively reported include the use of anxiolytic medications and effect on physiological parameters such as blood pressure and heart rate. Results A total of 15 studies were found to be eligible for inclusion (14 published trials and one conference abstract) in this review. Two-thirds of these studies showed statistically significant reduction in measures of patient anxiety or well-being with musical interventions. Meta-analysis included six studies (n = 695) and showed statistically significant reduction in mean STAI-S scores with music (−3.95 points; 95% confidence −5.53 and −2.37; p value less than 0.005). Conclusion and relevance In conclusion, music is a safe and easily administered intervention that can be used for anxiety reduction among patients undergoing cardiac catheterization. Further research is needed to better evaluate the clinical implications associated with the anxiolytic effects of music interventions during cardiac catheterization.

BACKGROUND: Variations in the prevalence of traditional cardiac risk factors only partially account for geographic variations in the incidence of cardiovascular disease. We examined the extent to which preventive ambulatory health care services contribute to geographic variations in cardiovascular event rates. METHODS: We conducted a cohort study involving 5.5 million patients aged 40 to 79 years in Ontario, Canada, with no hospital stays for cardiovascular disease as of January 2008, through linkage of multiple population-based health databases. The primary outcome was the occurrence of a major cardiovascular event (myocardial infarction, stroke or cardiovascular-related death) over the following 5 years. We compared patient demographics, cardiac risk factors and ambulatory health care services across the province’s 14 health service regions, known as Local Health Integration Networks (LHINs), and evaluated the contribution of these variables to regional variations in cardiovascular event rates. RESULTS: Cardiovascular event rates across LHINs varied from 3.2 to 5.7 events per 1000 person-years. Compared with residents of high-rate LHINs, those of low-rate health regions received physician services more often (e.g., 4.2 v. 3.5 mean annual family physician visits, p value for LHIN-level trend = 0.01) and were screened for risk factors more often. Low-rate LHINs were also more likely to achieve treatment targets for hypercholes-terolemia (51.8% v. 49.6% of patients, p = 0.03) and controlled hypertension (67.4% v. 53.3%, p = 0.04). Differences in patient and health system factors accounted for 74.5% of the variation in events between LHINs, of which 15.5% was attributable to health system factors alone. INTERPRETATION: Preventive ambulatory health care services were provided more frequently in health regions with lower cardiovascular event rates. Health system interventions to improve equitable access to preventive care might improve cardiovascular outcomes.

To examine the relationship between cardiac rehabilitation participation and health service expenditures in Ontario, Canada.A total of 6284 patients referred to cardiac rehabilitation between April 1, 2003, and December 31, 2010, were linked to 6284 matched cardiac rehabilitation eligible nonreferred controls and followed over a 3-year period across multiple linked administrative databases to identify health service utilization expenditures and mortality. All patients had previous cardiac hospitalizations within the preceding year. Four cardiac rehabilitation eligible groups of patients were balanced using propensity score weights: (1) no referral; (2) no participation; (3) low participation levels (ie, attending67% of prescheduled classes); and (4) high participation levels (ie, attending ≥67% prescheduled classes). Each group of patients was balanced in age, sex, geography, socioeconomic status, previous hospitalizations, ambulatory care conditions, cardiovascular risk factors, comorbidities, and previous health care expenditures. Generalized linear models were used to examine differences in health service expenditures (from all sources including hospitalizations, physician visits, diagnostic tests, and drugs for those older than 65 years) per "eligible day alive" over the 3-year period.Compared with the nonreferred population, health service expenditures followed a dose-response relationship and were lowest in patients who had the highest cardiac rehabilitation programmatic participation levels (P.001). Cost differences across groups separated early, remained divergent, and applied to all components of health care expenditures (P.001). Sensitivity analyses confirmed that the findings were not secondary to reverse causality.Participation in cardiac rehabilitation is associated with lower long-term health service utilization expenditures within a publicly funded health care system.

BACKGROUND Routine stress testing is commonly used after percutaneous coronary intervention (PCI) to detect in-stent restenosis or suboptimal procedure results; however, recent studies suggest that such testing is rarely indicated. Our main objectives were to assess temporal trends in utilization of stress testing and to determine factors associated with its use. METHODS We conducted an observational study involving all patients who had undergone PCI in Ontario, Canada, from Apr. 1, 2004, to Mar. 31, 2012. The main outcome was stress testing within 2 years after PCI. We constructed multivariable logistic regression models to determine factors associated with the use of stress tests. RESULTS Our cohort consisted of 128 380 patients who underwent PCI procedures. The 2-year rate of stress testing declined significantly, from 68.1% among patients who underwent PCI in 2004 to 60.4% in 2012 (p < 0.001). Similar reductions were observed regardless of patients' risk of restenosis and type of stent received. Patients who were older or had diabetes mellitus, prior myocardial infarction, heart failure or other comorbidities were significantly less likely to undergo stress testing. In contrast, patients with higher income and those whose PCI was performed in a nonteaching hospital were significantly more likely to undergo stress testing. INTERPRETATION We observed a decrease in the use of stress testing after PCI procedures over time. However, stress tests were not performed in accordance with patients' higher baseline risk of adverse outcomes or risk of restenosis. Instead, many nonclinical factors, such as patients' socioeconomic status and hospitals' teaching status, were associated with higher use of stress tests.

Comparative cardiovascular risk factor care across North America is unknown. We aimed to determine current performance in Canada and the United States (US).A systematic review was conducted of Medline and EMBASE (to June 1, 2014). Eligible studies reported on screening, awareness, treatment, or control rates for hypertension, dyslipidemia, diabetes, and smoking. Categorical performance 'ratings' on the basis of the most successful US health plans were used to classify rates as suboptimal (50%), below target (50%-70%), above target (70%-90%), or optimal (90%).A total of 127 studies reporting on 10,510,324 individuals across North America were included. Hypertension awareness (84.3%) and treatment (82.0%) rates in Canada and the US (82.7% and 75.6%, respectively) were above target, whereas control in both nations was below target (68.1% vs 51.8%, respectively). Canadian awareness, treatment, and control rates for dyslipidemia (42.7%, 40.9%, and 41.5%, respectively) were suboptimal, and American indicators were generally below target (61.5%, 43.0%, and 63.6%, respectively). Canada and the US showed diabetes awareness (88.2% vs 86.8%) and treatment rates (82.3% vs 82.5%) above target. However, glucose control was suboptimal in Canada (35.3%), and below target in the US (58.8%). There was a modest decline in absolute smoking prevalence rates in Canada from 1999 to 2013 (25.2% to 14.6%). Screening for tobacco use (72.2%) and counselling rates (73.8%) in the US were above target.Substantial variation exists in cardiovascular risk factor care across North America. Standardized reporting, dissemination of practice guidelines, and setting explicit goal-directed targets for performance might facilitate improvement.

Background Delayed discharge, captured as alternate-level-of-care days, represents inefficient use of high-demand acute care resources and results in potentially poorer patient outcomes. We performed a study to determine the extent of alternate-level-of-care days among patients who survived hypoxic-ischemic brain injury in inpatient hospital care in Ontario and to identify predictors of alternate-level-of-care use in this population. Methods A population-based cohort of acute care survivors of hypoxic-ischemic brain injury aged 20 years or more from 2002/03 through 2011/12 was identified. We used 2 case definitions, the more specific identifying patients with a most responsible diagnosis of "anoxic brain damage," and the more sensitive capturing additional likely causative conditions as the most responsible diagnosis. Multivariable zero-inflated negative binomial regression was used to estimate independent effects on the relative incidence of alternate-level-of-care days. Results We identified 491 patients using the specific case definition and 669 patients using the extended case definition. After deaths were excluded, 232 patients (47.2%) and 278 patients (41.6%), respectively, had at least 1 alternate-level-of-care day (median 20 and 19 d, respectively). In both cohorts, decreasing age, no special care unit hours and acute care episode earlier in the study period were predictive of increased alternate-level-of-care days relative to length of stay. Discharge disposition and psychiatric/behavioural comorbidity were most predictive of having any alternate-level-of-care days. Interpretation Patients with hypoxic-ischemic brain injury had a greater proportion of alternate-level-of-care days than has been reported for patients with other types of acquired brain injury. This finding suggests that substantial barriers to appropriate discharge exist for this population. Predictors of increased alternate-level-of-care days were also shown to be unique. Further study of care deficits among patients with hypoxic-ischemic brain injury is warranted.

Background The prognostic importance of high-density lipoprotein cholesterol (HDL-C) as a specific risk factor for cardiovascular (CV) disease has been challenged by recent clinical trials and genetic studies. Objectives This study sought to reappraise the association of HDL-C level with CV and non-CV mortality using a “big data” approach. Methods An observational cohort study was conducted using the CANHEART (Cardiovascular Health in Ambulatory Care Research Team) dataset, which was created by linking together 17 different individual-level data sources. People were included if they were between 40 and 105 years old on January 1, 2008, living in Ontario, Canada, without previous CV conditions or severe comorbidities, and had an outpatient fasting cholesterol measurement in the year prior to the inception date. The primary outcome was cause-specific mortality. Results A total of 631,762 individuals were included. The mean age of our cohort was 57.2 years, 55.4% were women, and mean HDL-C level was 55.2 mg/dl. There were 17,952 deaths during a mean follow-up of 4.9 ± 0.4 years. The overall all-cause mortality rate was 8.1 per 1,000 person-years for men and 6.6 per 1,000 person-years for women. Individuals with lower HDL-C levels were more likely to have low incomes, unhealthy lifestyle, higher triglycerides levels, other cardiac risk factors, and medical comorbidities. Individuals with lower HDL-C levels were independently associated with higher risk of CV, cancer, and other mortality compared with individuals in the reference ranges of HDL-C levels. In addition, individuals with higher HDL levels (>70 mg/dl in men, >90 mg/dl in women) had increased hazard of non-CV mortality. Conclusions Complex associations exist between HDL-C levels and sociodemographic, lifestyle, comorbidity factors, and mortality. HDL-C level is unlikely to represent a CV-specific risk factor given similarities in its associations with non-CV outcomes.

This article explores five interwoven principles about relationship that impact on attentional focus as it relates to the practice of clinical hypnosis. It first reviews how relationship is an irreducible feature of life that greatly predates the arrival of human beings. Second, it describes brain structures that, from an evolutionary perspective, appeared relatively recently, and the neuropsychological abilities those structures confer on human relationships. Third, it links those social brain structures to trance, an inborn response to novelty that is an important feature of our adaptive learning capacity. It further suggests that narrative is a multilevel concept that is deeply embodied and constitutes the sorbate from which hypnotic interactions can draw their rich impact. Finally, the article posits that hypnosis represents a skill set through which attuned clinicians engage in co-creative dances with clients, where the choreography of their interaction attends and responds to spontaneously arising and/or deliberately seeded opportunities for adaptive change. Reconstructed descriptions of interactions with clients are provided to illustrate the application of the principles presented.

A systematic review and network meta-analysis (NMA) of randomized controlled trials (RCTs) evaluating the core components of cardiac rehabilitation (CR), nutritional counseling (NC), risk factor modification (RFM), psychosocial management (PM), patient education (PE), and exercise training (ET)) was undertaken. Published RCTs were identified from database inception dates to April 2017, and risk of bias assessed using Cochrane’s tool. Endpoints included mortality (all-cause and cardiovascular (CV)) and morbidity (fatal and non-fatal myocardial infarction (MI), coronary artery bypass surgery (CABG), percutaneous coronary intervention (PCI), and hospitalization (all-cause and CV)). Meta-regression models decomposed treatment effects into the main effects of core components, and two-way or all-way interactions between them. Ultimately, 148 RCTs (50,965 participants) were included. Main effects models were best fitting for mortality (e.g., for all-cause, specifically PM (hazard ratio HR = 0.68, 95% credible interval CrI = 0.54⁻0.85) and ET (HR = 0.75, 95% CrI = 0.60⁻0.92) components effective), MI (e.g., for all-cause, specifically PM (hazard ratio HR = 0.76, 95% credible interval CrI = 0.57⁻0.99), ET (HR = 0.75, 95% CrI = 0.56⁻0.99) and PE (HR = 0.68, 95% CrI = 0.47⁻0.99) components effective) and hospitalization (e.g., all-cause, PM (HR = 0.76, 95% CrI = 0.58⁻0.96) effective). For revascularization (including CABG and PCI individually), the full interaction model was best-fitting. Given that each component, individual or in combination, was associated with mortality and/or morbidity, recommendations for comprehensive CR are warranted.

Objective The aim of this study was to determine the mechanisms by which Rhythmic Auditory Music Stimulation (RAMS) improves exercise among patients participating in cardiac rehabilitation. Methods 168 English speaking patients over the age of 18 years, were recruited from the Cardiac Rehabilitation and Prevention Program. Participants were randomly assigned to one of three groups (n = 56 each) as part of a 12-week intervention: (1) RAMS (2) preference-based audiobooks, or (3) white noise or silence audio-controls. All participants received an iPod with the audio intervention to maintain blinding. Study outcomes included pace-deviation between actual vs. prescribed exercise, self-reported arousal, perceived exertion, task-attentiveness during exercise and perceptual experiences associated with the audio-content itself. Trial registry Clinicaltrials. gov NCT02946060 . Results An individual's actual exercise pace was highly correlated with their prescribed exercise pace, with no significant differences in pace deviation across interventions (P = 0.61). Patients randomized to RAMS or audiobooks reported significantly lower arousal scores during exercise (P = 0.01), lower exercise-attentiveness (P Conclusions RAMS playlists and audiobooks induced a mood-enhancing task-distraction effect during exercise. Such findings may underscore the potential benefits of preference-based audio-content during exercise.

Cardiac rehabilitation (CR) is a proven model of secondary prevention. Indicated cardiac conditions for CR are well established, and participation of these patients results in significantly lower mortality and morbidity when compared with usual care. There are approximately 170 CR programs in Canada, which varies widely by province. There is a grossly insufficient capacity to treat all patients with cardiac indications in Canada and beyond. The density of CR services is about half that in the United States, at 1 program per 208,823 inhabitants or 1 program per 7779 patients with cardiac disease. Despite the Canadian Cardiovascular Society's target of 85% referral for CR for cardiac inpatients with the appropriate indications, significantly fewer patients are referred for CR. Moreover, certain patient groups—such as women, ethnocultural minorities, and those of low socioeconomic status—are less likely to access CR, despite greater need because of poorer outcomes. CR appears to be reaching a healthier population that is perhaps more adherent to secondary prevention recommendations and hence in less need of the limited CR spots available. The reasons for CR underuse are well established and include factors at patient, referring provider, CR program, and health system levels. A Cochrane review has established some effective interventions to increase CR use, and these must be implemented more broadly. We must advocate for CR reimbursement. Finally, we must reallocate our CR resources to patients with the greatest need. This may involve risk stratification, with subsequent allocation of lower-risk patients to a more widely available, lower-cost, and effective alternative model of CR.

Conversational hypnosis has been promoted as both more congruent with mechanisms of psychobiological change and more feasibly integrated into clinical care than the more dominant, ritualistic, hierarchical, induction-based Standards of Training in Clinical Hypnosis. Further, it has been argued that, in teaching the legacy standard, clinical hypnosis training lacks pedagogical integrity. This article builds on these premises by piloting a mixed-methods approach to studying the pedagogy and participant evaluations of two professional education events that focused on conversational hypnosis. Results indicate that this is an effective methodology for studying the impact of teaching hypnosis hypnotically and fostering wider integration of hypnosis into health and care.

Background The clinical effectiveness of cardiac rehabilitation (CR) on health-related quality of life (HRQOL) is an area that has not been consistently explored. The objective of this systematic review was to evaluate the effectiveness of providing any core component of CR on HRQOL domains. Methods We performed a meta-analysis and meta-regression of randomized controlled trials (RCTs) on the core components of CR. RCTs included adult patients with diagnosed coronary artery disease via angiography, myocardial infarction, angina, or who had undergone coronary revascularization. The Cochrane Library, MEDLINE, EMBASE, CINAHL, SCI-EXPANDED, Psych INFO, and Web of Science were searched from inception to April 27, 2017. Outcomes included overall, physical, emotional, and social HRQOL. Outcomes were reported as standardized mean change (SMC) with 95% confidence intervals (CIs). Effect size changes of 0.2, 0.5, and 0.8 SD units reflect a small, moderate, and large effect, respectively. Results Forty-nine reports of 41 RCTs with 11,747 patients were included. Summary effect sizes were: overall HRQOL SMC, 0.28 (95% CI, 0.05-0.50), physical HRQOL SMC, 0.47 (95% CI, 0.13-0.81), emotional HRQOL SMC, 0.37 (95% CI, −0.02 to 0.77), and social HRQOL SMC, 0.13 (95% CI, −0.06 to 0.32). Meta-regression revealed type of CR intervention and year of publication as positive statistically significant treatment effect modifiers. Conclusions Receiving CR was shown to improve HRQOL, with exercise-, nonexercise-, and psychological-based interventions playing a vital role. Although these improvements in HRQOL were modest they still reflect an incremental benefit compared with receiving usual care.

Background— Immigrants from ethnic minority groups represent an increasing proportion of the population in many high-income countries, but little is known about the causes and amount of variation between various immigrant groups in the incidence of major cardiovascular events. Methods and Results— We conducted the Cardiovascular Health in Ambulatory Care Research Team (CANHEART) Immigrant Study, a big data initiative, linking information from Citizenship and Immigration Canada’s Permanent Resident database to 9 population-based health databases. A cohort of 824 662 first-generation immigrants aged 30 to 74 as of January 2002 from 8 major ethnic groups and 201 countries of birth who immigrated to Ontario, Canada between 1985 and 2000 were compared with a reference group of 5.2 million long-term residents. The overall 10-year age-standardized incidence of major cardiovascular events was 30% lower among immigrants than among long-term residents. East Asian immigrants (predominantly ethnic Chinese) had the lowest incidence overall (2.4 in males, 1.1 in females per 1000 person-years), but this increased with greater duration of stay in Canada. South Asian immigrants, including those born in Guyana, had the highest event rates (8.9 in males, 3.6 in females per 1000 person-years), along with immigrants born in Iraq and Afghanistan. Adjustment for traditional risk factors reduced but did not eliminate the differences in cardiovascular risk between various ethnic groups and long-term residents. Conclusions— Striking differences in the incidence of cardiovascular events exist among immigrants to Canada from different ethnic backgrounds. Traditional risk factors explain a part but not all of these differences.

BACKGROUND The objective of this study was to determine the effect of care in the home (CHM) compared with usual care (UC) in patients with chronic heart failure (CHF) on clinical outcomes and healthcare use including a cost-effectiveness analysis. METHODS A systematic literature search on MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, as well as Centre for Reviews and Dissemination was conducted to identify randomized controlled trials comparing CHM with UC in CHF. The randomized controlled trials meeting inclusion criteria were meta-analyzed by outcome, and the quality of evidence for each outcome was evaluated using Grading of Recommendations Assessment, Development, and Evaluation system. A cost-effectiveness model was developed to estimate costs and quality-adjusted life years. RESULTS Six randomized controlled trials were identified from 1277 citations. Care in the home was predominately provided by a single health professional consisting of nurse-led education of varying duration and frequency. One study included pharmacist-led CHM. Care in the home showed a decreased risk for all-cause mortality and hospitalizations combined (risk ratio, 0.88; 95% confidence interval [CI], 0.80-0.97), but not all-cause mortality alone (risk ratio, 0.92; 95% CI, 0.81-1.04). Care in the home resulted in fewer hospitalizations (mean difference, -1.03; 95% CI, -1.53 to -0.53) and fewer emergency department visits (mean difference, -1.32; 95% CI, -1.87 to -0.77). Quality of life also improved with CHM delivered by nurses. Critical appraisal of the quality of evidence suggests uncertainty in the estimates for a number of outcomes. Care in the home resulted in a savings of $10,665 and a gain of 0.11 quality-adjusted life years compared with UC. CONCLUSIONS In conclusion, the beneficial effect of CHM in CHF is by reducing mortality and hospitalizations combined. Care in the home in CHF seems to be more effective and less costly compared with UC.

The purpose of this study was to develop a questionnaire to facilitate the design of acceptable financial health incentive programs. A multiphase psychometric questionnaire development method was used. Theoretical and literature reviews and three focus groups generated a pool of content areas and items. New items were developed to ensure adequate content coverage. Field testing was conducted with a convenience sample of cardiac rehabilitation (CR) patients (n = 59) to establish face and construct validity (p = 0.021) and reliability (intraclass coefficients = 0.42-0.87). The final questionnaire is comprised of 23 items. This questionnaire builds on previous attempts to explore acceptability by sampling a wider range of instrumental and affective attitudes and by measuring the effect of program features on the likelihood of incentive program participation. Future research is now needed to examine whether tailoring incentives to preferences assessed by the questionnaire improves uptake and effectiveness.

Timely access, adherence, and efficacy of cardiac rehabilitation programs (CRP) are important given the potential to mitigate or reverse the side effects of immunosuppressive medications, weight gain, and cardiovascular deconditioning that place heart transplant (HT) recipients at increased cardiovascular risk. However, there is a dearth of information on use and efficacy of CRPs. Therefore, we examined process indicators (time to referral and correlates, program adherence) and clinical outcome indicators (functional capacity (VO(2peak)), anthropometrics) of CR post-HT compared to post-coronary artery bypass graft (CABG).Baseline, 6-month exercise stress test results, and anthropometrics were examined retrospectively among consecutively enrolled post-HT and age-matched and sex-matched CABG patients. Time to referral and program entry, attendance, and completion rates were also measured.Heart transplant (n=43) and CABG patients were referred 24.9 ± 48.9 and 2.1 ± 3.6 months, respectively, after surgery (P=0.003). Once referred, there was no difference in elapsed-time to program entry (P=0.2). There was a positive relationship between time to referral and baseline waist circumference (r=0.5, P=0.001), body mass index (r=0.5, P=0.002), hip circumference (r=0.4, P=0.008), and body fat percentage (r=0.4, P=0.03) in HT. Heart transplant and CABG patients had similar rates of CRP dropout (27.9% vs. 37.2% respectively, P=0.4). There was improvement in VO(2peak) for HT (2.4 ± 4.2 mL/kg/min; P=0.02) and CABG (5.5 ± 5.4 mL/kg/min, P0.001), but was greater for CABG (P=0.04). Anthropometric measures remained stable for both cohorts (P0.05).There is a lengthy delay in time from HT to CRP referral, though once referred, gain significant benefit in functional capacity. The appropriateness of this wait needs to be elucidated; however, it appears that longer wait times are associated with adverse effects on body composition.

Background: The magnitude, consistency, and manner of association between sedentary time and outcomes independent of physical activity remain unclear. Purpose: To quantify the association between sedentary time and hospitalizations, all-cause mortality, cardiovascular disease, diabetes, and cancer in adults independent of physical activity. Data sources: English-language studies in MEDLINE, PubMed, EMBASE, CINAHL, Cochrane Library, Web of Knowledge, and Google Scholar databases were searched through August 2014 with hand-searching of in-text citations and no publication date limitations. Study selection: Studies assessing sedentary behavior in adults, adjusted for physical activity and correlated to at least 1 outcome. Data extraction: Two independent reviewers performed data abstraction and quality assessment, and a third reviewer resolved inconsistencies. Data synthesis: Forty-seven articles met our eligibility criteria. Meta-analyses were performed on outcomes for cardiovascular disease and diabetes (14 studies), cancer (14 studies), and all-cause mortality (13 studies). Prospective cohort designs were used in all but 3 studies; sedentary times were quantified using self-report in all but 1 study. Significant hazard ratio (HR) associations were found with all-cause mortality (HR, 1.240 [95% CI, 1.090 to 1.410]), cardiovascular disease mortality (HR, 1.179 [CI, 1.106 to 1.257]), cardiovascular disease incidence (HR, 1.143 [CI, 1.002 to 1.729]), cancer mortality (HR, 1.173 [CI, 1.108 to 1.242]), cancer incidence (HR, 1.130 [CI, 1.053 to 1.213]), and type 2 diabetes incidence (HR, 1.910 [CI, 1.642 to 2.222]). Hazard ratios associated with sedentary time and outcomes were generally more pronounced at lower levels of physical activity than at higher levels. Limitation: There was marked heterogeneity in research designs and the assessment of sedentary time and physical activity. Conclusion: Prolonged sedentary time was independently associated with deleterious health outcomes regardless of physical activity. Primary funding source: None.

The pharmaceutical market accounts for over (US) $1 trillion dollars in revenue per year worldwide, over one third of which is generated from sales of generic drugs.1 Available evidence suggests that on average, 48% of the total volume of this market among Organization for Economic Cooperation and Development nations comprised generic medications.2 Specifically in the United States, generic drugs comprise 84% of the total volume and 28% of the total value of the pharmaceutical market. However, significant variations in the uptake and costs of generic prescriptions are observed, which are partially attributable to differences in formulary management (pharmacy benefit managers), as well as variations in regulatory, substitution, and pricing policies between countries. Although manufactures must prove that generic analogues are bioequivalent to their brand-name comparators, the validity of generic drug substitution policies and their investment returns rest on the assumption that such drugs are clinically interchangeable. The extent to which such assumptions have been tested and proven remains unclear. See Article by Leclerc et al It is with this context that we read with interest the article by Leclerc et al3 in this month’s issue of Circulation: Cardiovascular Quality and Outcomes . This study used the Quebec Integrated Chronic Disease Surveillance System to examine the monthly rates of adverse events among 136 177 losartan, valsartan, and candesartan users aged 66 years and beyond, during the 24 months before and 12 months after the commercialization of these generic agents. The authors tracked each patient over time and identified the date at which the patient switched from the brand-name to the generic drug (ie, defined as the commercialization date). Using interrupted time-series analyses, the authors compared monthly adverse event rates (as defined by emergency room visits and hospitalizations) between generics and brands, before and after the commercialization date. The authors …

To understand the awareness of sedentary behavior, as well as the perceived facilitators and barriers to reducing sedentary behaviors from the perspectives of patients undertaking an exercise-based cardiac rehabilitation program, and from staff involved in supporting patient self-management.A qualitative study was conducted at a large cardiac rehabilitation program in a metropolitan city in Canada. Guided by an ecological framework, semi-structured interviews were conducted individually with 15 patients, and in two focus groups with six staff. Transcribed interviews were analyzed by thematic analysis.Patients placed little importance on reducing sedentary behavior as they were unconvinced of the health benefits, did not perceive themselves to be sedentary, or associated such behaviors with enjoyment and relaxation. While staff were aware of the risks, they saw them as less critical than other health behaviors. Intrapersonal factors (physical and psychosocial health) and environment factors (the information environment, socio-cultural factors) within leisure time, the home, and work, influenced sedentary behavior.While these findings require further testing, future interventions may be effective if aimed at increasing awareness of the health benefits of reducing sedentary behavior, utilizing existing behavior change strategies, and using a participatory approach to tailor strategies to patients. Implications for rehabilitation Cardiac rehabilitation programs effectively use exercise promotion to improve the health of people with established cardiovascular disease. As sedentary lifestyles become more prevalent, recommendations to reduce the health risks of prolonged sedentary behavior that are specific to the characteristics and prognostic profiles of cardiac rehabilitation patients are needed. Cardiac rehabilitation programs must consider extending existing behavior change strategies utilized for exercise promotion towards addressing sedentary behaviors in order to be effective at reducing the sedentary time of patients. A participatory approach involving both patients and health professionals can support patients in reducing their sedentary behavior by providing a supportive environment for behavior change, increasing awareness and understanding of risks, discussing the feasibility of potential strategies, and setting achievable and actionable goals.

On-site attendance to prescheduled cardiac rehabilitation visits has been shown to be associated with improved outcomes following cardiac rehabilitation. The extent to which on-site programmatic attendance represents a healthy-adherer effect remains unknown.This retrospective cohort study consisted of 17,000 consecutively referred patients to a cardiac rehabilitation program in Ontario, Canada. On-site attendance at prescheduled visits was our primary exposure variable. The primary outcome was all-cause death or hospitalization at two years following the expected program completion date, irrespective of drop-out. Secondary outcomes included adherence to statins, health-seeking preventative health visits, and changes in clinical risk-profiles. Cox proportional hazards adjusted for baseline sociodemographic, clinical and comorbid characteristics.Among the 12,440 patients who attended at least one prescheduled on-site visit, on-site attendance was inversely correlated with baseline smoking rates and body mass index at program entry. After adjustment for baseline factors, the risk of death or hospitalization progressively fell with incremental increases in on-site attendance (adjusted hazard ratio for each 10% increase in on-site attendance: 0.96; 95% confidence interval: 0.93-0.99, p = 0.007). Such associations were driven predominantly by differences in non-cardiovascular hospitalizations. Incremental increases in on-site attendance were associated with improvements in cardiopulmonary fitness and body mass index (both p 0.001), better attendance of preventative care physician visits (p 0.001) and higher medication adherence to statins (p = 0.007).Associations between on-site attendance at cardiac rehabilitation and outcomes may represent a healthy-adherer effect. Future research must evaluate the clinical utility of on-site attendance as a behavioral health-adherence metric for cardiac rehabilitation monitoring and surveillance.

Background— Higher-risk patients may not receive evidence-based therapy because of limited life expectancy, which is a composite measure that encompasses many patient factors, including age, frailty, and comorbidities. In this study, we evaluated the extent to which treatment care gaps can be explained by a difference in projected life expectancy. Methods and Results— An observational cohort study was conducted on acute myocardial infarction patients hospitalized in Ontario, Canada. Projected life expectancy was estimated using actual survival data with extrapolation using proportional hazard models adjusting for important covariates. The relationship between projected life expectancy with statins and reperfusion therapy was examined using generalized linear models. Among the 7001 acute myocardial infarction patients, 84.3% were prescribed statins and 72.9% were treated with reperfusion therapy. When projected life expectancy was P Conclusions— Life expectancy of a patient strongly influences evidence-based treatment in acute myocardial infarction. It was seen not only among patients with limited life expectancies but also among those with many years to live. Treatment care gaps may reflect clinicians’ synthesis about frailty and life-expectancy gains.

Financial health incentives, such as paying people to exercise, remain controversial despite widespread implementation. This focus group study explored the acceptability of incentives among a sample of Canadian cardiac rehabilitation (CR) patients (n = 15). Focus groups were conducted between March and April 2013 until further sampling ceased to produce new analytical concepts. A thematic analysis approach was adopted in analysing the data. Three broad themes emerged from the focus groups. First, ethical concerns were prominent. Half of participants disagreed with the incentive approach believing that it was unfair, unnecessary or a waste of limited resources. Second, ethical concerns were mitigated in considering a range of incentive features including type, size and source. Specifically, privately sponsored (not government funded) health-promoting voucher-based incentives (e.g., grocery or gym vouchers) were perceived to be highly acceptable. Third, if designed like this, then financial incentives were considered potentially effective in motivating behaviour change and in reducing economic barriers to exercise participation. Overall, the majority of participants welcomed incentives if ethical concerns were addressed through thoughtful incentive programme design. The results of this focus group study will inform the design of a financial health incentive feasibility RCT to promote post-CR programme exercise compliance in this population.

The legacy model of professional clinical hypnosis training presents a restrictive frame increasingly incompatible with our evolving understanding of psychobiology, health, and care. Emerging science recognizes human experience not as disease and diagnosis, but as manifestations of individual, uniquely-endowed, adaptively self-regulating systems. Hypnosis is a particularly well-suited discipline for effecting beneficial change in this paradigm. Training in clinical hypnosis must progress from the current linearly-structured, diagnosis-based, reductionist model toward a more responsive, naturalistic, and client-centered curriculum in order to remain relevant and accessible to clinicians beginning to integrate it into their practices. To that end, this article extends Hope and Sugarman's (2015) thesis of hypnosis as a skill set for systemic perturbation and reorientation to consider what those skills may be, the principles on which they are based, and how they may be taught. Parsing a clinical vignette reveals how incorporation of novelty and uncertainty results in less restrictive and more naturalistic hypnotic encounters that, in response to client-generated cues, elicit psychophysiological plasticity. This disruptive hypnosis education and training framework extends the utility and benefit of applied clinical hypnosis.

Context Less than 5% of U.S. adults accumulate the required dose of exercise to maintain health. Behavioral economics has stimulated renewed interest in economic-based, population-level health interventions to address this issue. Despite widespread implementation of financial incentive-based public health and workplace wellness policies, the effects of financial incentives on exercise initiation and maintenance in adults remain unclear. Evidence acquisition A systematic search of 15 electronic databases for RCTs reporting the impact of financial incentives on exercise-related behaviors and outcomes was conducted in June 2012. A meta-analysis of exercise session attendance among included studies was conducted in April 2013. A qualitative analysis was conducted in February 2013 and structured along eight features of financial incentive design. Evidence synthesis Eleven studies were included (N=1453; ages 18–85 years and 50% female). Pooled results favored the incentive condition ( z =3.81, p 1 year), and two studies found exercise adherence persisted after the incentive was withdrawn. Promising incentive design feature attributes were noted. Assured, or "sure thing," incentives and objective behavioral assessment in particular appear to moderate incentive effectiveness. Previously sedentary adults responded favorably to incentives 100% of the time ( n =4). Conclusions The effect estimate from the meta-analysis suggests that financial incentives increase exercise session attendance for interventions up to 6 months in duration. Similarly, a simple count of positive ( n =8) and null ( n =3) effect studies suggests that financial incentives can increase exercise adherence in adults in the short term (

The purpose of this study was to examine utilization and growth in echocardiography among the general population of Ontario between 2001 and 2009. The age- and sex-adjusted rates of echocardiography grew from 39.1 per 1,000 persons in 2001 to 59.9 per 1,000 persons in 2009, for an annual rate of increase of 5.5%. Repeat echocardiograms increased at a rate of 10.6% per year and accounted for 25.3% of all procedures in 2009 as compared to 18.5% in 2002. While significant increases in echocardiography utilization were observed, opportunities may exist to improve the clinical utility of the echocardiograms performed in Ontario.

Background: The safety of exercise therapy (ET) in patients with an implantable cardioverter defibrillator (ICD) remains unclear. We sought to explore the current state of evidence and conduct a systematic review on the safety of ICDs during ET. Methods: A systematic review was performed using CINAHL, Cochrane Library, EMBASE, Google Scholar, MEDLINE, PubMed (excluding Medline records), and Web of Science databases searched through April 2015. Studies that quantitively assessed adverse events during ET and after ET in ICD patients compared to one of two control groups (non-ICD ET or non-ET ICD patients) were included. The primary outcome was adverse events during ET. Secondary outcomes were events during ET and follow-up. Results: Meta-analyses were performed on ten eligible studies. During ET, ICD patients experienced an increased risk of adverse events [relative risk (RR)=2.63, 95% confidence interval (CI) (1.71-4.05), P=0.01] compared to non-ICD controls. There was no significant increase risk of adverse events compared to non-ET ICD controls [RR=0.99, 95% CI (0.11-8.95), P=0.99]. ET-ICD patients had fewer adverse events during follow-up compared to non-ET ICD populations [RR=0.90, 95% CI (0.82- 0.99), P=0.02]. A sensitivity analysis including only randomized trials showed similar findings showed no difference in the primary outcome. Conclusions: Our analysis showed increased adverse event during exercise in ICD patients as compared with non-ICD patients. Comparative adverse event rates between exercising and sedentary ICD patients were similar during ET and lower after ET, suggesting that exercise can be safe and potentially protective among ICD patients. More rigorous data from larger randomized trials is needed to further quantify the incremental risk of exercise in high-risk ICD populations.

Marzolini S, Oh PI, Alter D, Stewart DE, Grace SL; on behalf of the Cardiac Rehab: Care Continuity through Automatic Referral Evaluation Investigators. Musculoskeletal comorbidities in cardiac patients: prevalence, predictors, and health services utilization. Objectives To describe the prevalence of musculoskeletal conditions (MSKC) in patients with coronary artery disease (CAD); to examine the sociodemographic, clinical, and psychosocial predictors of these comorbidities; and to describe health care utilization by musculoskeletal comorbidity status. Design This was a cross-sectional, observational study in which patients were administered a questionnaire in the hospital and 1 year later. Setting Eleven hospitals in Ontario, Canada. Participants CAD patients (N=1803). Interventions Not applicable. Main Outcome Measures Sociodemographic, MSKC, clinical, and psychosocial factors were ascertained via questionnaire and in-hospital chart extraction. A health care utilization questionnaire was mailed 1 year later. Results Over half (56%) of the patients with CAD had MSKCs, with arthritis/joint pain accounting for 64.4% of these MSKCs. Patients who were older (odds ratio [OR]=1.03), women (OR=1.87), white (OR=1.80), with higher body mass index (OR=1.05), depressive symptoms (OR=1.92), and lower family income (OR=1.46) were more likely to present with MSKCs. One year posthospitalization, a greater proportion of those with MSKCs reported ≥1 cardiac-related emergency department visit (33.2% vs 28.3%, P=.03), hospital admission (30.7% vs 22%, P=.006), more primary care physician visits (6.6±5.6 vs 5.7±4.6, P Conclusions Over half of the patients hospitalized for CAD have MSKCs. Those with MSKCs have a physical and psychosocial profile that places them at greater cardiovascular risk than those with CAD only, explaining, in part, their greater health care utilization. Despite a greater need for comprehensive risk factor management in patients with MSKCs, fewer were referred to cardiac rehabilitation.
