The addition of tick-boxes related to tobacco cessation improves smoking-related documentation in the anaesthesia chart.

The Australian and New Zealand College of Anaesthetists (ANZCA) 'Guidelines on Smoking as Related to the Perioperative Period (PS12)' recommends that anaesthetists should always ask about smoking, advise quitting and refer patients to their general practitioner (GP) or a telephone quit-line for quit support. In this study we evaluated the effect of adding tick-boxes for 'quit advice given' and 'referral to GP/Quitline' to anaesthesia charts of elective surgical patients to assess whether this intervention changed documentation of compliance with the ANZCA guideline. The anaesthesia charts of all smokers were reviewed for evidence of asking, advising and referring, over two three-month periods (n=999) separated by the intervention of placing a sticker to modify the preoperative charts of all elective patients which added tick-box prompts of advice and referral. No educational campaigns occurred to encourage tick-box use. No changes were made to non-elective charts. Evidence of advice to quit was 1.8% prior to, rising to 18.7% after, the intervention (P <0.001), while evidence of referral rose from 0.9% to 5.8%. There was negligible change in non-elective patients, who did not receive the intervention. The addition of tick-boxes improved the documentation of smoking cessation support, but as documented rates of quit support remained relatively low even after the intervention, tick-boxes alone cannot be relied upon to improve alignment of care with the ANZCA guidelines.

Effectiveness of a brief community outreach tobacco cessation intervention in India: a cluster-randomised controlled trial (the BABEX Trial)

BackgroundTobacco use kills half a million people every month, most in low–middle income countries (LMICs). There is an urgent need to identify potentially low-cost, scalable tobacco cessation interventions for these...

Protocol for a randomised pragmatic policy trial of nicotine products for quitting or long-term substitution in smokers.

BackgroundSmoking is Australia’s leading preventable cause of premature mortality and a major contributor to the national disease burden. If quit rates do not dramatically improve, then smoking will continue to be a major public health issue for decades to come. Harm-reduction approaches using novel nicotine products like e-cigarettes as long term replacements for smoking have the potential to improve quit rates. However, little research has assessed such approaches.Methods/DesignDesign: Three-arm parallel-group pragmatic randomised controlled trial.Participants: People living in Australia who are at least 18 years old, smoke five or more cigarettes per day and are willing to try a sample of nicotine products.Intervention: Participants are randomised to receive standard quit advice and medicinal nicotine (Condition A); quit or substitute advice and medicinal nicotine (Condition B); or quit or substitute advice and medicinal nicotine and e-cigarettes (Condition C). Participants choose which (if any) nicotine products to receive to try in a free sample pack followed by a two to three week free supply of their favourite product(s) and the option to purchase more at a discounted price. Follow-up surveys will assess nicotine product use and smoking.Primary outcome: Continuous abstinence for at least 6 months.Target sample size: 1600 people (Condition A: 340; Condition B: 630; Condition C: 630) provides at least 80 % power at p = 0.05 to detect a 5 % difference in abstinence rates between each condition.DiscussionThis trial will provide data on tobacco harm-reduction approaches and in particular the use of e-cigarettes as a replacement for smoking.Trial registrationAustralian and New Zealand Clinical Trials Registry: ACTRN12612001210864.

A systematic review of the quality of reporting in published smoking cessation trials for pregnant women: an explanation for the evidence-practice gap?

BackgroundTo facilitate translation of evidence into clinical practice, it is critical that clear, specific, and detailed information about interventions is provided in publications to promote replication, appropriate aggregation in meta-analysis, and implementation. This study examined whether twenty elements of interventions deemed essential for such translational application were reported in sufficient detail in smoking cessation trials with pregnant women.MethodsSearches of electronic databases using MeSH terms and keywords identified peer-reviewed English language studies published between 2001 and 2012. Eligible studies reported a smoking cessation intervention targeted at pregnant women and met Cochrane’s Effective Practice and Organization of Care group study design criteria. Each intervention arm of eligible studies was assessed against the developed twenty criteria.ResultsThirty relevant studies reported the findings of 45 intervention arms. The mode of delivery of the intervention was reported in 100% of intervention arms. Other well-reported criteria included reporting of the provider who delivered the intervention (96%), sample characteristics (80%), and the intervention setting (80%). Criteria not reported adequately included care provided to women who relapse (96% not reported), details about training given to providers (77% not reported), and the method of quit advice advised (76% not reported). No studies reported 100% of relevant criteria.ConclusionsCurrent standards of reporting of intervention content and implementation are suboptimal. The use of smoking cessation specific checklists for reporting of trials, standard reporting using behaviour change taxonomies, and the publication of protocols as supplements should be considered as ways of improving the specificity of reporting.Electronic supplementary materialThe online version of this article (doi:10.1186/s13012-014-0094-z) contains supplementary material, which is available to authorized users.

Smokers know little of their increased surgical risks and may quit on surgical advice

Smoking cessation before surgery improves perioperative outcomes and some smokers may quit if undergoing surgery. Quitting smoking in community settings is influenced by physician quit advice and knowledge of smoking hazards, but there are few data on whether this applies in perioperative settings. Survey on day of surgery of elective patients who reported being a smoker at the time of wait-list placement. Duration of smoking abstinence before surgery (if any) and length timing of failed quit attempts was determined. Sources of any quit advice before surgery, including from physicians, and patient knowledge on hazards of smoking and surgery were questioned. While on the waiting list, 44/177 smokers reported quitting (>24 h) before surgery and 42/177 others made an attempt. Quitting was usually brief. Fewer than 40% of smokers answered yes (correct answer) to questions on whether smoking increased wound infection rates, worsened wound healing, increased anaesthetic complications or increased post-operative pain. Incorrect answers (no) were less likely in quitters than those smoking until surgery (OR 0.41, 95% CI 0.25-0.68). Patients still smoking by admission recalled quit advice from a surgeon in 22.6% of cases, while wait-list quitters recalled surgical quit advice in 43.2% of cases (OR 2.6 95% CI 1.2-5.4 P = 0.01). Effects of general practitioner quit advice were significant (OR 3.2 95% CI 1.5-6.8 P = 0.004) while anaesthetists, nurse and hospital brochure advice were not. Improving patient knowledge of the perioperative risks of smoking and increased physician advice to quit may improve smoking abstinence at surgery.

Effectiveness of two intensive treatment methods for smoking cessation and relapse prevention in patients with coronary heart disease: study protocol and baseline description.

BackgroundThere is no more effective intervention for secondary prevention of coronary heart disease than smoking cessation. Yet, evidence about the (cost-)effectiveness of smoking cessation treatment methods for cardiac inpatients that also suit nursing practice is scarce. This protocol describes the design of a study on the (cost-)effectiveness of two intensive smoking cessation interventions for hospitalised cardiac patients as well as first results on the inclusion rates and the characteristics of the study population.Methods/designAn experimental study design is used in eight cardiac wards of hospitals throughout the Netherlands to assess the (cost-)effectiveness of two intensive smoking cessation counselling methods both combined with nicotine replacement therapy. Randomization is conducted at the ward level (cross-over). Baseline and follow-up measurements after six and 12 months are obtained. Upon admission to the cardiac ward, nurses assess patients’ smoking behaviour, ensure a quit advice and subsequently refer patients for either telephone counselling or face-to-face counselling. The counselling interventions have a comparable structure and content but differ in provider and delivery method, and in duration. Both counselling interventions are compared with a control group receiving no additional treatment beyond the usual care. Between December 2009 and June 2011, 245 cardiac patients who smoked prior to hospitalisation were included in the usual care group, 223 in the telephone counselling group and 157 in the face-to-face counselling group. Patients are predominantly male and have a mean age of 57 years. Acute coronary syndrome is the most frequently reported admission diagnosis. The ultimate goal of the study is to assess the effects of the interventions on smoking abstinence and their cost-effectiveness. Telephone counselling is expected to be more (cost-)effective in highly motivated patients and patients with high SES, whereas face-to-face counselling is expected to be more (cost-)effective in less motivated patients and patients with low SES.DiscussionThis study examines two intensive smoking cessation interventions for cardiac patients using a multi-centre trial with eight cardiac wards. Although not all eligible patients could be included and the distribution of patients is skewed in the different groups, the results will be able to provide valuable insight into effects and costs of counselling interventions varying in delivery mode and intensity, also concerning subgroups.Trial registrationDutch Trial Register NTR2144

A randomized, controlled trial of adding expired carbon monoxide feedback to brief stop smoking advice: Evaluation of cognitive and behavioral effects.

To determine the effect of adding biomarker feedback (expired air carbon monoxide) to standard quit advice on cognitive antecedents of behavior change and smoking cessation and to identify potential effect moderators and mediators. Smokers (N = 160) were randomized to a control (quit advice plus leaflet) or an intervention condition (as control group plus carbon-monoxide level feedback). Cognitive measures were assessed immediately after the intervention and behavioral measures at 6 months' follow-up. Primary outcome measures were threat and efficacy appraisal, fear arousal, and intention to stop smoking. Secondary outcome measures were quit attempts within the last 6 months and 7-day point prevalence abstinence. Threat appraisal was significantly enhanced in the intervention compared with the control group, t(158) = 2.29, p = .023, as was intention to stop smoking in the next month, t(151) = 2.9, p = .004. However, this effect on intention to stop smoking was short-lived. Groups did not differ in terms of quit attempts or abstinence at follow-up, but the intervention increased the likelihood of cessation in smokers with higher self-efficacy, χ2(1) = 5.82, p = .016. Carbon-monoxide level feedback enhances the effect of brief quit advice on cognitive antecedents of behavior change and smoking cessation rates but further research is required to confirm the longevity of this effect and its applicability to smokers with low self-efficacy.

Evaluating NSW SmokeCheck: a culturally specific smoking cessation training program for health professionals working in Aboriginal health

This paper reports on the evaluation of a culturally specific smoking cessation training program (SmokeCheck) for health professionals working in Aboriginal health in NSW. Training aimed to increase professionals' knowledge, skills and confidence to offer an evidence-based quit smoking brief intervention to Aboriginal clients. Using a quasi-experimental pre-post with 165 matched intervention participants, surveys were completed immediately before (baseline) and 6-months post training. The control group were on a waiting list for 6 months before receiving the intervention, and completed surveys at baseline, immediately before training and 3-6 months following training. Surveys assessed knowledge, skills and confidence to deliver the intervention, availability of resources, and smoke-free status of homes. Post training, a higher proportion of intervention group participants were more confident talking about health effects (22%, p=0.001), offering quit advice (27%, p=0.001), assessing readiness to quit (31%, p=0.001) and initiating a conversation about smoking (24%, p=0.001). After training, more participants reported providing advice about NRT (15%, p=0.001), ETS (12%, p=0.006), and reducing tobacco use (10%, p=0.034), but no changes were reported in smoking or intention to quit. Conversely, the control group showed no significant changes. SmokeCheck training strengthened participants' knowledge, skills and confidence to deliver a smoking cessation intervention to Aboriginal clients.'

Emergency department-initiated tobacco dependence treatment.

To examine the feasibility of a fax referral program to increase enrollment in tobacco dependence treatment in emergency department (ED) patients. The control group received quit advice and printed information; the intervention group also received a faxed referral that generated telephone contacts. Treatment enrollment was higher in the intervention group (13.5% vs 2.7%). Only the faxed referral was associated with treatment enrollment. An ED intervention is feasible. Faxed referral resulted in a 5-fold increase in tobacco treatment enrollment. The ED may be an opportune setting to facilitate smoking-cessation behavior change among lower income, underserved patients.

Cigarette Smoking and Advice to Quit in a National Sample of Homeless Adults

Cigarette smoking is common among homeless people, but its characteristics in this vulnerable population have not been studied at a national level. Whether homeless smokers receive advice to quit from healthcare providers is also unknown. To determine the prevalence and predictors of current cigarette smoking, smoking cessation, and receipt of clinician advice to quit in a national sample of homeless adults. This study analyzed data from 966 adult respondents to the 2003 Health Care for the Homeless User Survey, representing more than 436,000 people nationally. Using multivariable logistic regression, the independent predictors of smoking, quitting, and receiving advice to quit were identified. Analyses were conducted in 2008-2009. The prevalence of current smoking was 73%. The lifetime quit rate among ever smokers was 9%. Among past-year smokers, 54% reported receiving clinician advice to quit. Factors independently associated with current smoking included out-of-home placement in childhood (AOR=2.79, 95% CI=1.03, 7.52); victimization while homeless (AOR=2.36, 95% CI=1.15, 4.83); past-year employment (AOR=2.52, 95% CI=1.13, 5.58); and prior illicit drug use (AOR=7.21, 95% CI=3.11, 16.7) or problem alcohol use (AOR=7.42, 95% CI=2.51, 21.9). Respondents with multiple homeless episodes had higher odds of receiving quit advice (AOR=2.51, 95% CI=1.30, 4.83) but lower odds of quitting (AOR=0.47, 95% CI=0.29, 0.78). Compared to the general population, homeless people are far more likely to smoke and much less likely to quit, even though more than half of smokers received quit advice in the past year. Interventions for homeless smokers should address the unique comorbidities and vulnerabilities of this population.

Association between Participation in Outpatient Cardiac Rehabilitation and Self-Reported Receipt of Lifestyle Advice from a Healthcare Provider: Results of a Population-Based Cross-Sectional Survey.

We test the hypothesis that the odds of self-reported receipt of lifestyle advice from a health care provider will be lower among outpatient cardiac rehabilitation (OCR) nonattendees and nonreferred patients compared to OCR attendees. Logistic regression was used to analyse cross-sectional data provided by 65% (4971/7678) of patients aged 20 to 84 years discharged from public hospitals with a diagnosis indicating eligibility for OCR between 2002 and 2007. Among respondents, 71% (3518) and 55% (2724) recalled advice regarding physical activity and diet, respectively, while 88% (592/674) of smokers recalled quit advice. OCR attendance was low: 36% (1764) of respondents reported attending OCR, 11% (552) did not attend following referral, and 45% (2217) did not recall being invited. The odds of recalling advice regarding physical activity and diet were significantly lower among OCR nonattendees compared to attendees (OR 0.34, 95% CI 0.21, 0.56 and OR 0.33, 95% CI 0.25, 0.44, resp.) and among nonreferred respondents compared to OCR attendees (OR 0.10, 95% CI 0.07, 0.15 and OR 0.17, 95% CI 0.14, 0.22, resp.). Patients hospitalised for coronary heart disease should be referred to OCR or a suitable alternative to improve recall of lifestyle advice that will reduce the risk of further coronary events.

Secondary prevention for acute coronary syndrome in rural South Australia: Are drugs best? What about the rest?

Acute coronary syndrome (ACS) is a major cause of morbidity and mortality worldwide. Current Australian clinical guidelines recommend all patients with ACS receive comprehensive secondary prevention services to address this burden. Optimal patient outcomes rely on the timely and effective implementation of proven therapies and for secondary prevention to be successful, pharmacological interventions must be combined with cardiovascular disease (CVD) risk factor identification and management. The ability to implement clinical guidelines is also reliant on available resources, yet many rural populations in Australia do not have access to structured secondary prevention services, and the level of support available to them in the form of unstructured services is unclear. Our aim was to examine the scope of secondary prevention in a 'significantly restricted' rural region of South Australia that does not have access to structured secondary prevention services. A retrospective analysis of medical records was undertaken to identify documented evidence of assessment and intervention for medical, lifestyle and behavioural CVD risk factors in hospital and at follow up in general practice (GP) clinics. Eligible participants were patients admitted to hospital in the Riverland Region of South Australia with myocardial infarction over a 12 month period. Of 77 eligible participants, permission was received to access the medical records of 55 patients in the hospital setting, and 34 of these 55 patients in GP clinic follow up. Most patients received baseline assessment for previous AMI (98%), history of hypertension (82%), history of diabetes (78%), and smoking status (76%). Most poorly documented was history of dyslipidaemia (53%) and obesity/ overweight (2%). Prescribing rates for recommended ACS medications at the time of hospital discharge were aspirin (90%), beta blockers (55%), ACE inhibitors (42%), lipid lowering medication (66%) and clopidogrel (64%). Overall prescribing rates in the 12 month study period rose to 80% or higher for all recommended medications. There was no evidence of interventions for smoking and obesity/ overweight in the hospital setting and 45% of smokers in the GP clinic setting received quit advice. Measurement of biomedical risk factors (blood lipid analysis and blood glucose levels) was suboptimal, and there was no evidence of a written action plan for chest pain for any participants. Unstructured services provided some of the recommended elements of secondary prevention. However, deficits in care exist that have the potential to negatively impact patient outcomes in this already disadvantaged population. Future research needs to focus on the extent to which this and other rural and remote health care services are working within current clinical guidelines for the management of ACS, and subsequent patient outcomes. Urgent consideration must also be given to the introduction and evaluation of a more structured and consistent approach in this and other rural and remote regions of Australia. The development of rehabilitation and prevention services that build on existing strengths and resources have the potential to widen access, enhance current services and ensure care is based on best practice guidelines. This in turn may reduce the burden of CVD and improve the overall health and quality of life for patients in rural and remote Australia.

Effect on cessation counseling of documenting smoking status as a routine vital sign: an ACORN study.

Guidelines encourage primary care clinicians to document smoking status when obtaining patients' blood pressure, temperature, and pulse rate (vital signs), but whether this practice promotes cessation counseling is unclear. We examined whether the vital sign intervention influences patient-reported frequency and intensity of tobacco cessation counseling. This study was a cluster-randomized, controlled trial conducted in the Virginia Ambulatory Care Outcomes Research Network (ACORN). At intervention practices, nurses and medical assistants were instructed to assess the tobacco use status of every adult patient and record it with the traditional vital signs. Control practices did not use any systematic tobacco screening or identification system. Outcomes were the proportion of smokers reporting clinician counseling of any kind and the frequency of 2 counseling subcomponents: simple quit advice and more intensive discussion. A total of 6,729 adult patients (1,149 smokers) at 18 primary care practices completed exit questionnaires during a 6-month comparison period. Among 561 smokers at intervention practices, 61.9% reported receiving any counseling, compared with 53.4% of the 588 smokers at control practices, for a difference of 8.6% (P = .04). The effect was largely restricted to simple advice, which was reported by 59.9% of intervention patients and 51.5% of control patients (P=.04). There was no significant increase in more extensive discussion, with 32.5% and 29.3% of patients at intervention and control practices, respectively, reporting this type of counseling (P=.18). The vital sign intervention promotes tobacco counseling at primary care practices through a modest increase in simple advice to quit. When implemented as a stand-alone intervention, it does not appear to increase intensive counseling.

Views of Ontarians about health professionals' smoking cessation advice.

Health professionals have important roles in helping smokers quit. However, it is not known how the public, especially smokers, view smoking cessation advice from different health professionals. We added questions regarding opinions and experiences with health professionals' smoking cessation advice to the 2002 CAMH Monitor, an annual random-digit-dialled survey of adult Ontarians. We report on how good a source of advice physicians, pharmacists, and dentists are perceived to be, how likely smokers are to consult each of these professionals, who smokers would ask for advice on the use of NRT, and advice received by smokers in the past year. About two thirds of respondents viewed physicians as a very good source of advice on quitting, compared to just over one third and about one quarter who thought this of pharmacists and dentists, respectively. Over half of current smokers would be very likely to ask a physician for quit advice, compared to about 20% and only 3% for a pharmacist or a dentist, respectively. Among smokers, over 40% would first ask a physician for advice on NRT; about 20% would first ask a pharmacist. About 42% and 8% of current smokers reported that they received advice in the past year from a physician and pharmacist, respectively. Smokers are receptive to quit advice from physicians, but less likely to ask other health professionals. Few smokers received advice from pharmacists and dentists. Increasing the reach of quit advice requires both increased professional intervention and education of the public.

Factors Associated With Smoking Cessation Counseling at Clinical Encounters: The Behavioral Risk Factor Surveillance System (BRFSS) 2000

Characterize factors associated with smoking-cessation counseling in clinical encounters. Cross-sectional analysis of Behavioral Risk Factor Surveillance System (BRFSS) 2000 data. U.S. households. 10,582 smokers (aged > or = 18 years) reporting one or more clinical encounters during the prior year. Multivariate-adjusted odds ratios (OR) and 95% confidence intervals (CI) for quit advice associated with respondent and encounter variables. Almost 55% of respondents were advised to quit smoking. Young men were advised to quit least often. Increasing age (18-24, 25-39, 40-64, > or = 65 years) was associated with increasing odds of receiving quit advice (OR = 1.33, CI 1.10-1.61) for men. Other positive associations with quit advice included patient education, BMI, diagnosis of asthma, and private health insurance. Patients seeing physicians had greater odds of being advised to quit smoking (OR = 3.29, CI 2.13-5.06) than those seeing dentists. There was a 4% to 23% chance of receiving quit advice at any given nondental clinical encounter; the odds of such counseling did not rise significantly with the number of visits. Smoking cessation counseling may be provided preferentially on the basis of patient demographics, and often is not provided at all. In a given year, just over half of smoking patients are advised to quit, and such counseling is provided at less than a quarter of clinical encounters.

Purpose Characterize factors associated with smoking-cessation counseling in clinical encounters. Design Cross-sectional analysis of Behavioral Risk Factor Surveillance System (BRFSS) 2000 data. Setting U.S. households. Subjects 10,582 smokers (aged ≥ 18 years) reporting one or more clinical encounters during the prior year. Measures Multivariate-adjusted odds ratios (OR) and 95 % confidence intervals (CI) for quit advice associated with respondent and encounter variables. Results Almost 55 % of respondents were advised to quit smoking. Young men were advised to quit least often. Increasing age (18–24, 25–39, 40–64, ≥65 years) was associated with increasing odds of receiving quit advice (OR = 1.33, CI 1.10–1.61) for men. Other positive associations with quit advice included patient education, BMI, diagnosis of asthma, and private health insurance. Patients seeing physicians had greater odds of being advised to quit smoking (OR = 3.29, CI 2.13–5.06) than those seeing dentists. There was a 4% to 23% chance of receiving quit advice at any given nondental clinical encounter; the odds of such counseling did not rise significantly with the number of visits. Conclusion Smoking cessation counseling may be provided preferentially on the basis of patient demographics, and often is not provided at all. In a given year, just over half of smoking patients are advised to quit, and such counseling is provided at less than a quarter of clinical encounters.

Does methodology affect the ability to monitor tobacco control activities? implications for HEDIS and other performance measures

Background It is unclear whether methodological differences in sample size, survey methods, and analysis approach significantly affect the ability to accurately monitor tobacco control activities and to make rate comparisons. Methods Questionnaires were sent to 64,764 members of nine health plans in diverse settings soon after their visit to a primary care clinician. Of these 41,677 completed responses were received. We compared responses received by mail and by telephone follow-up for the percentage of smokers, characteristics of smokers, and their rates of reporting physician cessation counseling. Results Overall, 10.2% were current cigarette smokers, but the proportion was 8.6% for mail responders and 17.2% for phone follow-up responders. Smokers identified by phone follow-up were different from mail responders in most demographic and smoking characteristics and their reports of clinical smoking cessation activities differed for six of nine clinician smoking cessation actions. Calculating advice rates as a proportion of visits produced lower rates with more dispersion among plan rates than doing so without accounting for visit variation. Conclusions Smoking surveys using only mailed questionnaires dramatically undersample smokers, especially in some demographic groups. Comparisons of tobacco counseling among health plans can be improved by ensuring an adequate sample size and response rate and by analyzing by frequency of quit advice.

Do patients listen when we tell them to stop smoking?

Objective To investigate patients' views regarding dentists' smoking cessation advice. Design Survey questionnaire. Setting One hundred and thirty five dental practices in Sydney, Australia. Subjects Two thousand, four hundred and fifty one dental patients. Results One thousand, one hundred and sixty pre-consultation questionnaires were obtained (RR=80%), 302 (26%) were self-reported smokers. From these, 623 post-consultation questionnaires were returned (RR = 54%). Most patients expected dentists to be interested in their smoking status (n = 847/1160, 73%, 95% CI: 70% to 76%) and to discuss smoking with them (n = 713/1160, 61%, 95% CI: 59% to 64%), however, smokers were significantly less likely to respond as such compared with non-smokers (p < 0.001). Smokers and non-smokers equally would not change dentist even if asked about their smoking status opportunistically (59% versus 62%) (OR = 0.91, 95% CI: 0.67 to 1.22). Less than one third of all smokers would try to quit if their dentist suggested they do so (n = 90/302, 30%, 95% CI: 25% to 35%). Smokers' recall of quit advice from their recent consultation was low (n = 22/124, 18%). Conclusions Smoking cessation advice by dentists is not self-evidently effective. These findings behove interventional research to ascertain efficacy of smoking cessation advice delivered by dentists before admonishing changes in routine clinical practice.
