Prevalence, Perceptions, and Patterns of Cannabis Use Among Cardiac Inpatients at a Tertiary-Care Hospital: A Cross-Sectional Survey.

Background: Cannabis use may adversely affect cardiovascular health. Patterns of use by cardiac patients are unknown. We evaluated the prevalence, perceptions, and patterns of cannabis use among cardiac inpatients. Methods: A consecutive cross-section of cardiac inpatients, hospitalized between November 2019 and May 2020, were surveyed in-person or via telephone. Descriptive statistics and logistic regression were used to examine the characteristics of cannabis use. Results: The prevalence of past-12-month cannabis use was 13.8% (95% confidence interval [CI]: 11.8%-16.0%). Characteristics independently associated with cannabis use were as follows: age < 64 years (< 44 years, odds ratio [OR] = 3.96 [95% CI: 1.65-9.53]; age 45-64 years, OR = 2.72 [95% CI: 1.65-4.47]); tobacco use in the previous 6 months (OR = 1.91 [95% CI: 1.18-3.07]); having a cannabis smoker in one's primary social group (OR = 4.17 [95% CI: 2.73-6.38]); and a history of a mental health diagnosis (OR = 1.82 [95% CI: 1.19-2.79]). Among those using cannabis, 70.5% reported smoking or vaping it; 47.2% reported daily use. Most did not know the tetrahydrocannabinol (THC; 71.6%) or cannabidiol (CBD; 83.3%) content of their cannabis, or the dose of cannabis in their edibles (66.7%). As defined by Canada's Lower Risk Cannabis Use Guidelines, 96.7% of cannabis users reported ≥ 1 higher-risk use behaviour (mean = 2.3, standard deviation = 1.2). Over 60% of patients expressed no intention to quit or reduce cannabis use in the next 6 months. Conclusions: Cannabis use appears prevalent among cardiac patients. Most users demonstrated higher-risk use behaviours and low intentions to quit. Further work is needed to understand the impacts of cannabis use on the cardiovascular system and to develop guidelines and educational tools relating to lower-risk use, for cardiac patients and providers.

Contexte: L'utilisation du cannabis peut nuire à la santé cardiovasculaire, mais les habitudes d'utilisation des patients atteints de troubles cardiaques ne sont pas connues. Nous avons évalué la prévalence, les perceptions et les habitudes d'utilisation du cannabis chez des patients hospitalisés présentant des troubles cardiaques. Méthodologie: Une analyse transversale a été réalisée en interrogeant en personne ou au téléphone des patients hospitalisés consécutivement entre novembre 2019 et mai 2020 et présentant des troubles cardiaques. Des statistiques descriptives et une régression logistique ont été utilisées pour examiner les caractéristiques liées à l'utilisation du cannabis. Résultats: La prévalence de l'utilisation du cannabis au cours des 12 mois précédents était de 13,8 % (intervalle de confiance [IC] à 95 % : 11,8 % à 16,0 %). Les caractéristiques indépendamment associées à l'utilisation du cannabis étaient les suivantes : âge < 64 ans (< 44 ans, rapport de cotes [RC] = 3,96 [IC à 95 % : 1,65 à 9,53]; âge de 45 à 64 ans, RC = 2,72 [IC à 95 % : 1,65 à 4,47]); tabagisme dans les six mois précédents (RC = 1,91 [IC à 95 % : 1,18 à 3,07]); présence d'un consommateur de cannabis au sein du cercle social principal (RC = 4,17 [IC à 95 % : 2,73 à 6,38]); et diagnostic antérieur lié à la santé mentale (RC = 1,82 [IC à 95 % : 1,19 à 2,79]). Parmi les utilisateurs de cannabis, 70,5 % d'entre eux ont rapporté qu'ils fumaient ou vapotaient et 47,2 % ont déclaré en consommer quotidiennement. La plupart ne connaissaient pas le contenu en tétrahydrocannabinol (THC; 71,6 %) ou en cannabidiol (CBD; 83,3 %) du cannabis consommé, ou la dose contenue dans les aliments à base de cannabis consommés (66,7 %). Au total, 96,7 % des utilisateurs de cannabis ont rapporté ≥ 1 comportement(s) à risque élevé (moyenne = 2,3, écart-type = 1,2) selon les Recommandations canadiennes pour l'usage du cannabis à moindre risque. Par ailleurs, plus de 60 % des patients n'ont exprimé aucune intention d'interrompre ou de diminuer leur consommation de cannabis au cours des six prochains mois. Conclusions: L'utilisation du cannabis semble courante chez les patients qui présentent des troubles cardiaques. La plupart des utilisateurs ont démontré des comportements à risque élevé, et une faible intention de mettre fin à leur consommation. D'autres études sont requises pour caractériser les répercussions de l'utilisation du cannabis sur l'appareil cardiovasculaire et élaborer des lignes directrices et des outils éducatifs à l'intention des patients atteints de troubles cardiaques et des professionnels de la santé en vue de favoriser un usage à moindre risque.

The Canadian Women's Heart Health Alliance Atlas on the Epidemiology, Diagnosis, and Management of Cardiovascular Disease in Women - Chapter 4: Sex- and Gender-Unique Disparities: CVD Across the Lifespan of a Woman.

Women have unique sex- and gender-related risk factors for cardiovascular disease (CVD) that can present or evolve over their lifespan. Pregnancy-associated conditions, polycystic ovarian syndrome, and menopause can increase a woman's risk of CVD. Women are at greater risk for autoimmune rheumatic disorders, which play a role in the predisposition and pathogenesis of CVD. The influence of traditional CVD risk factors (eg, smoking, hypertension, diabetes, obesity, physical inactivity, depression, anxiety, and family history) is greater in women than men. Finally, there are sex differences in the response to treatments for CVD risk and comorbid disease processes. In this Atlas chapter we review sex- and gender-unique CVD risk factors that can occur across a woman's lifespan, with the aim to reduce knowledge gaps and guide the development of optimal strategies for awareness and treatment.

Les femmes présentent des facteurs de risque de maladies cardiovasculaires (MCV) uniques, liés au sexe et au genre, qui peuvent se manifester ou évoluer tout au long de leur vie. Les troubles médicaux associés à la grossesse, le syndrome des ovaires polykystiques et la ménopause peuvent augmenter le risque de MCV chez une femme. Les femmes sont plus exposées aux troubles rhumatologiques auto-immuns, qui jouent un rôle dans la prédisposition et dans la pathogenèse des MCV. L'influence des facteurs de risque traditionnels pour les MCV (par exemple, le tabagisme, l'hypertension, le diabète, l'obésité, la sédentarité, la dépression, l'anxiété et les antécédents familiaux) est plus importante chez les femmes que chez les hommes. Enfin, il existe des différences entre les sexes dans la réponse aux traitements du risque de MCV et des processus pathologiques comorbides. Dans ce chapitre de l'Atlas, nous passons en revue les facteurs de risque de MCV propres au sexe et au genre qui peuvent survenir tout au long de la vie d'une femme, dans le but de réduire les lacunes dans les connaissances et d'orienter l'élaboration de stratégies optimales de sensibilisation et de traitement.

Implementation of a systematic tobacco treatment protocol in a surgical outpatient setting: a feasibility study.

Background: Smoking cessation programs started as late as 4 weeks before surgery reduce perioperative morbidity and death, yet outpatient clinic interventions are rarely provided. Our aim was to evaluate the feasibility of implementing a tobacco treatment protocol designed for an outpatient surgical setting. Methods: We completed a pre-post feasibility study of the implementation of a systematic, evidence-based tobacco treatment protocol in an outpatient colorectal surgery clinic. Outcomes included smoking prevalence, pre- and postimplementation smoker identification and intervention rates, recruitment, retention, smoking cessation and provider satisfaction. Results: Preimplementation, 15.5% of 116 surveyed patients were smokers. Fewer than 10% of surveyed patients reported being asked about smoking, and none were offered any cessation intervention. Over a 16-month postimplementation period, 1198 patients were seen on 2103 visits. Of these, 950 (79.3%) patients were asked smoking status on first visit and 1030 (86.0%) were asked on at least 1 visit. Of 169 identified smokers, 99 (58.6%) were referred to follow-up support using an opt-out approach. At 1-, 3- and 6-month follow-up, intention-to-quit rates among 78 enrolled patients were 24.4%, 22.9% and 19.2%, respectively. Postimplementation staff surveys reported that the protocol was easy to use, that staff would use it again and that it had positive patient responses. Conclusion: Implementation of our smoking cessation protocol in an outpatient surgical clinic was found to be feasible and used minimal clinic resources. This protocol could lead to increases in identification and documentation of smoking status, delivery of smoking cessation interventions and rates of smoking reduction and cessation.

Contexte: Les programmes d'abandon du tabagisme entamés jusqu'à 4 semaines avant une opération réduisent la morbidité et la mortalité périopératoires, mais les cliniques externes n'en proposent que rarement. L'étude visait à évaluer s'il est faisable d'appliquer un protocole de traitement du tabagisme pensé pour les milieux de soins chirurgicaux extrahospitaliers. Méthodes: Nous avons réalisé une étude de faisabilité pré- et postexpérimentale sur l'application d'un protocole de traitement systématique fondé sur des données probantes à une clinique externe de chirurgie colorectale. Les résultats à l'étude étaient les suivants : prévalence du tabagisme, identification des fumeurs et taux d'intervention avant et après la mise en place du protocole, recrutement, rétention, abandon du tabagisme et satisfaction des fournisseurs. Résultats: Au départ, 15,5 % des 116 patients sondés fumaient. Moins de 10 % des répondants avaient été questionnés sur leur statut tabagique, et aucun ne s'était vu proposer un programme d'abandon. Au cours des 16 mois suivant la mise en place du protocole, 1198 patients ont été rencontrés dans le cadre de 2103 consultations. Parmi eux, 950 (79,3 %) ont été interrogés sur leur statut tabagique à la première rencontre, et 1030 (86 %) l'ont été au moins 1 fois. Des 169 fumeurs identifiés, 99 (58,6 %) ont été orientés vers un programme de soutien selon une approche de consentement présumé. Après 1 mois, 24,4 % des 78 patients participants étaient déterminés à arrêter de fumer; 22,9 % l'étaient toujours après 3 mois, et 19,2 % après 6 mois. Les sondages menés a posteriori auprès du personnel indiquent que le protocole est facile à utiliser, que les employés s'en serviraient de nouveau, et que les patients l'ont accueilli favorablement. Conclusion: Il a été possible de mettre en place notre protocole d'abandon du tabagisme à une clinique externe de chirurgie, et ce en employant un minimum de ressources cliniques. Le protocole pourrait permettre de connaître et de consigner davantage de statuts tabagiques, d'orienter un plus grand nombre de fumeurs vers les programmes d'abandon et d'accroître les taux de réduction et d'abandon du tabagisme.

Smoking behaviour among nurses in Ontario: cross-sectional results from the Champlain Nurses' Study.

OBJECTIVE: Nurses comprise the largest professional group within the Canadian health care workforce. We aimed to assess the prevalence and correlates of smoking among nurses. METHODS: The Champlain Nurses' Study was a multi-centre, observational study that evaluated the physical activity levels and health of hospital-based nurses. Participants completed a series of self-report questionnaires addressing a variety of health indicators including smoking status and smoking history. Multi-level modelling was used to examine variability in smoking status across hospital sites and to identify correlates of current smoking. RESULTS: A total of 406 nurses, from 14 urban and rural hospitals, were included in this analysis. On average, the nurses were 42.9 (standard deviation (SD), 11.9) years old, had a waist circumference of 78.7 (95% confidence interval (CI): 77.5, 80.2) cm and body mass index of 25.9 (95% CI: 25.3, 26.5) kg/m2, worked in urban hospitals (81.3%), and had either a university bachelor's (46.9%) or college (39.6%) education. Most participants (92.0%) reported that they are not current smokers, 4.0% reported that they currently smoke occasionally, and 4.0% reported that they are current daily smokers. Smokers were more likely to be working in rural hospitals than urban hospitals (34.4% versus 17.4% respectively, p = 0.018), associated with having a higher waist circumference (mean difference = 4.5 (SD, 2.1), p = 0.035), a college but not university education (71.9% versus 36.9%, respectively, p < 0.001), lower scores for the Barriers Specific Self-Efficacy Scale (mean difference = - 9.7 (SD, 4.6), p = 0.038), and higher scores for the Profile of Mood States scale (mean difference = 2.0 (SD, 3.3), p = 0.007). The only correlate that remained statistically significant in the final, multivariate model was marital status; however, this analysis may be underpowered. CONCLUSIONS: The prevalence of nurse smokers in our population is lower than previous estimates, and consistent with global declines in cigarette smoking. However, smoking was still prominent and associated with several other risk factors. Given the important relationship between smoking and health, and the critical role that nurses play in health care delivery, they should be an important focus for smoking cessation initiatives and other health education initiatives.

Automated Telephone Follow-up for Smoking Cessation in Smokers With Coronary Heart Disease: A Randomized Controlled Trial.

INTRODUCTION: Smokers with coronary heart disease (CHD) benefit from in-hospital cessation treatment, but relapse is common without ongoing support postdischarge. The purpose of this study was to determine if smoking abstinence would be higher after hospital discharge in smokers who received automated telephone follow-up (ATF) and nurse-counseling, compared with a standard care (SC) control group. METHODS: A total of 440 smokers hospitalized with CHD were randomly assigned to the ATF group (n = 216) or to the SC group (n = 224). Participants in the ATF group received automated phone calls 3, 14, 30, 60, 90, 120, 150, and 180 days after hospital discharge. The ATF system posed questions concerning smoking status, confidence in staying smoke-free, and need for assistance. If flagged by the ATF system, a nurse-counselor provided additional counseling by phone. Self-reported continuous smoking abstinence was assessed 26 and 52 weeks postdischarge using intention-to-treat analysis. The main outcome measure was continuous abstinence for weeks 1-26 postdischarge. RESULTS: Participants in the ATF group achieved higher abstinence rates for weeks 1-26 than those in the SC group (odds ratio [OR] = 1.53, 95% confidence interval [CI] = 1.01 to 2.33). There was no significant difference between groups in abstinence rates for weeks 27-52 (OR = 1.37; 95% CI = 0.89 to 2.09). CONCLUSIONS: ATF-mediated follow-up helped smokers with CHD achieve abstinence during the intervention period. There was a trend toward clinically important improvements for weeks 27-52; but between-group differences for this time point did not achieve statistical significance. CLINICAL TRIAL NUMBER: NCT00449852. IMPLICATIONS: Automated telephone follow-up exerts its effect by reinforcing participants' efforts to be smoke-free and by proactively linking people requiring assistance to individualized support (eg, telephone counseling). This study shows that automated telephone follow-up can assist smokers with CHD in remaining smoke-free; however, the success of automated telephone follow-up is limited to the treatment period and abstinence rates after the treatment period were not statistically different from among those receiving standard care. Extended treatment via automated telephone follow-up may provide a solution to extend cessation assistance beyond hospital discharge.

From Good to Great: The Role of Performance Coaching in Enhancing Tobacco-Dependence Treatment Rates.

PURPOSE: The purpose of this study was to examine the incremental effect of performance coaching, delivered as part of a multicomponent intervention (Ottawa Model for Smoking Cessation [OMSC]), in increasing rates of tobacco-dependence treatment by primary care clinicians. METHODS: In a cluster-randomized controlled trial, 15 primary care practices were randomly assigned to 1 of the following active-treatment conditions: OMSC or OMSC plus performance coaching (OMSC+). All practices received support to implement the OMSC. In addition, clinicians in the OMSC+ group participated in a 1.5-hour skills-based coaching session and received an individualized performance report. All clinicians and a cross-sectional sample of their patients were surveyed before and 4 months after introduction of the interventions. The primary outcome measure was rates of tobacco-dependence treatment strategy (Ask, Advise, Assist, Arrange) delivery. Secondary outcomes were patient quit attempts and smoking abstinence measured at 6 months' follow-up. RESULTS: Primary care clinicians (166) and patients (1,990) were enrolled in the trial. Clinicians in the OMSC+ group had statistically greater rates of delivery for Ask (adjusted odds ratio [AOR] = 1.69; 95% CI, 1.05-2.72), Assist (AOR = 1.64; 95% CI, 1.08-2.49), and Arrange (AOR = 2.01; 95% CI, 1.22-3.31). Sensitivity analysis found that the rate of delivery for Advise was greater only among those clinicians who attended the coaching session (AOR = 1.65; 95% CI, 1.10-2.49; P = .02). No differences were documented between groups for cessation outcomes. CONCLUSIONS: Performance coaching significantly increased rates of tobacco-dependence treatment by primary care clinicians when delivered as part of a multicomponent intervention.

Prospective, Cluster-Randomized Trial to Implement the Ottawa Model for Smoking Cessation in Diabetes Education Programs in Ontario, Canada.

OBJECTIVE: To test whether a practice-level intervention to promote the systematic identification, treatment, and follow-up of smokers (the Ottawa Model for Smoking Cessation [OMSC]) would improve long-term abstinence rates among smoker-patients with type 2 diabetes or prediabetes receiving care from diabetes education programs in Ontario, Canada. RESEARCH DESIGN AND METHODS: The Tobacco Intervention in Diabetes Education study was a matched-pair, cluster-randomized clinical trial. Within each pair, sites were randomly allocated to either an OMSC intervention (n = 7) or a wait-list control (WLC) condition (n = 7). Diabetes education programs in the OMSC group introduced standardized processes to identify smokers and routinely provided smoking cessation interventions and follow-up. Smokers in the OMSC group received counseling, a discount card to partially cover the cost of smoking cessation medication, and follow-up telephone calls over a 6-month period. Diabetes education programs in the WLC condition were offered the OMSC intervention after a 1-year waiting period. Smokers in the WLC group received usual care for smoking cessation from their diabetes educator. The primary end point was carbon monoxide (CO)-confirmed 7-day point prevalence abstinence from smoking at 6-month follow-up. RESULTS: A total of 313 smokers (OMSC group n = 199, WLC group n = 114) with diabetes or prediabetes were enrolled. The CO-confirmed abstinence rate at 6 months was 11.1% in the OMSC group versus 2.6% in the WLC group (odds ratio 3.73 [95% CI 1.20, 11.58]; P = 0.02). CONCLUSIONS: Implementation of the OMSC in diabetes education programs resulted in clinically and statistically significant improvements in long-term abstinence among smokers with diabetes or prediabetes.

Increasing Rates of Tobacco Treatment Delivery in Primary Care Practice: Evaluation of the Ottawa Model for Smoking Cessation.

PURPOSE: We report on the effectiveness of the Ottawa Model for Smoking Cessation (OMSC), a multicomponent knowledge translation intervention, in increasing the rate at which primary care providers delivered smoking cessation interventions using the 3 A's model-Ask, Advise, and Act, and examine clinic-, provider-and patient-level determinants of 3 A's delivery. METHODS: We examined the effect of the knowledge translation intervention in 32 primary care practices in Ontario, Canada, by assessing a cross-sectional sample of patients before the implementation of the OMSC and a second cross-sectional sample following implementation. We used 3-level modeling (clinic, clinician, patient) to examine the main effects and predictors of 3 A's delivery. RESULTS: Four hundred eighty-one primary care clinicians and more than 3,500 tobacco users contributed data to the evaluation. Rates of delivery of the 3 A's increased significantly following program implementation (Ask: 55.3% vs 71.3%, P <.001; Advise: 45.5% vs 63.6%, P <.001; Act: 35.4% vs 54.4%, P <.001). The adjusted odds ratios (AOR) for the delivery of 3 A's between the pre- and post-assessments were AOR = 1.94; (95% CI, 1.61-2.34) for Ask, AOR = 1.92; (95% CI, 1.60-2.29) for Advise, and AOR = 2.03; (95% CI, 1.71-2.42) for Act. The quality of program implementation and the reason for clinic visit were associated with increased rates of 3 A's delivery. CONCLUSIONS: Implementation of the OMSC was associated with increased rates of smoking cessation treatment delivery. High quality implementation of the OMSC program was associated with increased rates of 3 A's delivery.

Effectiveness of performance coaching for enhancing rates of smoking cessation treatment delivery by primary care providers: Study protocol for a cluster randomized controlled trial.

UNLABELLED: Smoking cessation is one of the most powerful preventive interventions available to primary care providers. Rates of tobacco treatment delivery in primary care settings, however, remain sub-optimal. This paper reports on rationale, design, and protocol for a matched-paired, cluster-randomized controlled trial to compare the incremental effectiveness of performance coaching on physician delivery of smoking cessation assistance when delivered as part of a practice-level intervention for smoking cessation (the Ottawa Model for Smoking Cessation; OMSC). Outcome measures included frequency of provider smoking cessation treatment delivery, patient quit attempts, and 7-day point prevalence abstinence measured at 6 months, and changes in provider attitudes and beliefs related to smoking cessation treatment delivery. Primary care clinics were randomly assigned, using a matched paired design, to one of two treatment conditions: OMSC Group or OMSC+Performance Coaching Group. All practices were supported with implementing the OMSC. Half of the practices also received a 1.5 hour, skills-based, coaching session to address barriers encountered in the delivery of smoking cessation treatments and individualized performance feedback reports. All providers, and a cross sectional sample of patients from their practices, were surveyed before and after the implementation of the intervention. Multi-level modeling was used to compare intervention groups. If shown to be effective, the study will lead to an improved understanding of how to best assist clinicians to enhance the delivery of smoking cessation practice and will provide evidence to guide the design of smoking cessation interventions in primary care.

A pilot randomized controlled trial of smoking cessation in an outpatient respirology clinic.

OBJECTIVE: To assess the feasibility and potential effectiveness of a modified version of the Ottawa Model for Smoking Cessation in an outpatient respirology clinic. METHODS: Adult tobacco smokers attending the respirology clinic and willing to choose a quit date within one month of enrollment were randomly assigned to receive standard care or the intervention. Standard care participants received smoking cessation advice, a brochure and a prescription for smoking cessation medication if requested. Intervention participants received a $110 voucher to purchase smoking cessation pharmacotherapy and were registered to an automated calling system. Answers to automated calls determined which participants required nurse telephone counselling. Feasibility indicators included recruitment and retention rates, and intervention adherence. The effectiveness indicator was self-reported smoking status at 26 to 52 weeks. RESULTS: Forty-nine (54.4%) of 90 eligible smokers were randomly assigned to the intervention (n=23) or control (n=26) group. Self-reported smoking status at 26 to 52 weeks was available for 32 (65.3%) participants. The quit rate for intervention participants was 18.2% compared with 7.7% for controls (OR2.36 [95% CI 0.39 to 14.15]). CONCLUSION: It would be feasible to evaluate this intervention in a larger trial. Alternatives to face-to-face follow-up at the clinic are recommended.

Economic evaluation of a hospital-initiated intervention for smokers with chronic disease, in Ontario, Canada.

INTRODUCTION: Cigarette smoking causes many chronic diseases that are costly and result in frequent hospitalisation. Hospital-initiated smoking cessation interventions increase the likelihood that patients will become smoke-free. We modelled the cost-effectiveness of the Ottawa Model for Smoking Cessation (OMSC), an intervention that includes in-hospital counselling, pharmacotherapy and posthospital follow-up, compared to usual care among smokers hospitalised with acute myocardial infarction (AMI), unstable angina (UA), heart failure (HF), and chronic obstructive pulmonary disease (COPD). METHODS: We completed a cost-effectiveness analysis based on a decision-analytic model to assess smokers hospitalised in Ontario, Canada for AMI, UA, HF, and COPD, their risk of continuing to smoke and the effects of quitting on re-hospitalisation and mortality over a 1-year period. We calculated short-term and long-term cost-effectiveness ratios. Our primary outcome was 1-year cost per quality-adjusted life year (QALY) gained. RESULTS: From the hospital payer's perspective, delivery of the OMSC can be considered cost effective with 1-year cost per QALY gained of $C1386, and lifetime cost per QALY gained of $C68. In the first year, we calculated that provision of the OMSC to 15 326 smokers would generate 4689 quitters, and would prevent 116 rehospitalisations, 923 hospital days, and 119 deaths. Results were robust within numerous sensitivity analyses. DISCUSSION: The OMSC appears to be cost-effective from the hospital payer perspective. Important consideration is the relatively low intervention cost compared to the reduction in costs related to readmissions for illnesses associated with continued smoking.

Workplace physical activity interventions and moderate-to-vigorous intensity physical activity levels among working-age women: a systematic review protocol.

BACKGROUND: The rapid pace of modern life requires working-age women to juggle occupational, family and social demands. This modern lifestyle has been shown to have a detrimental effect on health, often associated with increased smoking and alcohol consumption, depression and cardiovascular disease risk factors. Despite the proven benefits of regular moderate-to-vigorous intensity physical activity (MVPA), few are meeting the current physical activity (PA) recommendations of 150 min of MVPA/week. It is important that appropriate and effective behavioural interventions targeting PA are developed and identified to improve the MVPA levels of working-age women. As these women spend a substantial proportion of their waking hours at work, workplaces may be an opportune, efficient and relatively controlled setting to implement programmes and strategies to target PA in an effort to improve MVPA levels and impact cardiometabolic health. The purposes of this systematic review are to compare the effectiveness of individual-level workplace interventions for increasing MVPA levels in working-age women in high-income/developed countries and examine the effectiveness of these interventions for improving the known beneficial health sequelae of MVPA. METHODS/DESIGN: Eight electronic databases will be searched to identify all prospective cohort and experimental studies that examine the impact of individual-level workplace interventions for increasing MVPA levels among working-age (mean age 18-65 years) women from high-income/developed countries. Grey literature including theses, dissertations and government reports will also be included. Study quality will be assessed using a modified Downs and Black checklist, and risk of bias will be assessed within and across all included studies using the Cochrane's risk of bias tool and Grades of Recommendation, Assessment, Development and Evaluation approach. Meta-analyses will be conducted where possible among studies with sufficient homogeneity. DISCUSSION: This review will determine the effectiveness of individual-level workplace interventions for increasing MVPA levels in working-age women in high-income/developed countries, and form a current, rigorous and reliable research base for policy makers and stakeholders to support the development and implementation of effective workplace interventions that increase MVPA levels in this population.

Examining sustainability in a hospital setting: case of smoking cessation.

BACKGROUND: The Ottawa Model of Smoking Cessation (OMSC) is a hospital-based smoking cessation program that is expanding across Canada. While the short-term effectiveness of hospital cessation programs has been documented, less is known about long-term sustainability. The purpose of this exploratory study was to understand how hospitals using the OMSC were addressing sustainability and determine if there were critical factors or issues that should be addressed as the program expanded. METHODS: Six hospitals that differed on OMSC program activities (identify and document smokers, advise quitting, provide medication, and offer follow-up) were intentionally selected, and two key informants per hospital were interviewed using a semi-structured interview guide. Key informants were asked to reflect on the initial decision to implement the OMSC, the current implementation process, and perceived sustainability of the program. Qualitative analysis of the interview transcripts was conducted and themes related to problem definition, stakeholder influence, and program features emerged. RESULTS: Sustainability was operationalized as higher performance of OMSC activities than at baseline. Factors identified in the literature as important for sustainability, such as program design, differences in implementation, organizational characteristics, and the community environment did not explain differences in program sustainability. Instead, key informants identified factors that reflected the interaction between how the health problem was defined by stakeholders, how priorities and concerns were addressed, features of the program itself, and fit within the hospital context and resources as being influential to the sustainability of the program. CONCLUSIONS: Applying a sustainability model to a hospital smoking cessation program allowed for an examination of how decisions made during implementation may impact sustainability. Examining these factors during implementation may provide insight into issues affecting program sustainability, and foster development of a sustainability plan. Based on this study, we suggest that sustainability plans should focus on enhancing interactions between the health problem, program features, and stakeholder influence.

Strategies to increase the delivery of smoking cessation treatments in primary care settings: a systematic review and meta-analysis.

OBJECTIVES: A systematic review and meta-analysis was conducted to evaluate evidence-based strategies for increasing the delivery of smoking cessation treatments in primary care clinics. METHODS: The review included studies published before January 1, 2009. The pooled odds-ratio (OR) was calculated for intervention group versus control group for practitioner performance for "5As" (Ask, Advise, Assess, Assist and Arrange) delivery and smoking abstinence. Multi-component interventions were defined as interventions which combined two or more intervention strategies. RESULTS: Thirty-seven trials met eligibility criteria. Evidence from multiple large-scale trials was found to support the efficacy of multi-component interventions in increasing "5As" delivery. The pooled OR for multi-component interventions compared to control was 1.79 [95% CI 1.6-2.1] for "ask", 1.6 [95% CI 1.4-1.8] for "advice", 9.3 [95% CI 6.8-12.8] for "assist" (quit date) and 3.5 [95% CI 2.8-4.2] for "assist" (prescribe medications). Evidence was also found to support the value of practice-level interventions in increasing 5As delivery. Adjunct counseling [OR 1.7; 95% CI 1.5-2.0] and multi-component interventions [OR 2.2; 95% CI 1.7-2.8] were found to significantly increase smoking abstinence. CONCLUSION: Multi-component interventions improve smoking outcomes in primary care settings. Future trials should attempt to isolate which components of multi-component interventions are required to optimize cost-effectiveness.

Smoking cessation for hospitalized smokers: an evaluation of the "Ottawa Model".

INTRODUCTION: Interventions for hospitalized smokers can increase long-term smoking cessation rates. The Ottawa Model for Smoking Cessation (the "Ottawa Model") is an application of the "5 A's" approach to cessation, customized to the hospital setting. This study evaluated the impact of implementing the Ottawa Model in 9 hospitals in eastern Ontario. METHODS: The RE-AIM (Reach, Efficacy, Adoption, Implementation, and Maintenance) framework was used to evaluate the intervention. Trained outreach facilitators assisted 9 hospitals to implement the Ottawa Model; program delivery was then monitored over a 1-year period using administrative data and data from a follow-up database. A before-and-after study was conducted to gauge the effect of the Ottawa Model program on cessation rates 6 months after hospitalization. Self-reports of smoking cessation were biochemically confirmed in a random sample of patients, and all cessation rates were corrected for potential misreporting. RESULTS: Sixty-nine percent of the expected number of smokers received the Ottawa Model intervention. Controlling for hospital, the confirmed 6-month continuous abstinence rate was higher after, than before, introduction of the Ottawa Model (29.4% vs. 18.3%; odds ratio = 1.71, 95% CI = 1.11-2.64; Z = 2.43; I(2) = 0%; p = .02). The intervention was more likely to accomplish counseling for smokers than delivery of medications or postdischarge follow-up. Attitudinal, managerial, and environmental challenges to program implementation were identified. DISCUSSION: Trained outreach facilitators successfully implemented the Ottawa Model in 9 hospitals leading to significantly higher long-term cessation rates. The public health implications of systematic cessation programs for hospitalized smokers are profound.
