Perceived barriers to smoking cessation in selected vulnerable groups: a systematic review of the qualitative and quantitative literature

Objectives To identify barriers that are common and unique to six selected vulnerable groups: low socioeconomic status; Indigenous; mental illness and substance abuse; homeless; prisoners; and at-risk youth. Design A systematic review was carried out to identify the perceived barriers to smoking cessation within six vulnerable groups. Data sources MEDLINE, EMBASE, CINAHL and PsycInfo were searched using keywords and MeSH terms from each databases inception published prior to March 2014. Study selection Studies that provided either qualitative or quantitative (ie, longitudinal, cross-sectional or cohort surveys) descriptions of self-reported perceived barriers to quitting smoking in one of the six aforementioned vulnerable groups were included. Data extraction Two authors independently assessed studies for inclusion and extracted data. Results 65 eligible papers were identified: 24 with low socioeconomic groups, 16 with Indigenous groups, 18 involving people with a mental illness, 3 with homeless groups, 2 involving prisoners and 1 involving at-risk youth. One study identified was carried out with participants who were homeless and addicted to alcohol and/or other drugs. Barriers common to all vulnerable groups included: smoking for stress management, lack of support from health and other service providers, and the high prevalence and acceptability of smoking in vulnerable communities. Unique barriers were identified for people with a mental illness (eg, maintenance of mental health), Indigenous groups (eg, cultural and historical norms), prisoners (eg, living conditions), people who are homeless (eg, competing priorities) and at-risk youth (eg, high accessibility of tobacco). Conclusions Vulnerable groups experience common barriers to smoking cessation, in addition to barriers that are unique to specific vulnerable groups. Individual-level, community-level and social network-level interventions are priority areas for future smoking cessation interventions within vulnerable groups. Trial registration number: A protocol for this review has been registered with PROSPERO International Prospective Register of Systematic Reviews (Identifier: CRD42013005761).

The social context of smoking: A qualitative study comparing smokers of high versus low socioeconomic position

BackgroundThe reductions in smoking prevalence in a number of industrialised countries are accompanied by a strong social gap and associated health inequality. Groups such as the World Health Organisation emphasise the importance of exploring potential causal factors for smoking such as socio-economic context & position. There has been little effort to compare the social context of smoking for smokers of high versus lower socio-economic position (SEP) to consider how tobacco control efforts might reduce smoking-related health inequality.MethodPurposive sampling was used to recruit participants for eight focus groups. The groups were segregated by age, gender and SEP. Samples were selected from suburbs within the Sydney metropolitan area defined as either high or low SEP based on the Socio Economic Index for Areas. Emergent themes were analysed according to Polands six dimensions of the social context of smoking. Differences according to SEP, age group and gender were explored.ResultsWhile there was commonality in social experiences for smokers across groups, some important aspects of the social context of smoking varied. Smokers of high SEP appeared to be aware of particular social pressures not to smoke on five of the six social context dimensions (power, body, identity, consumption and place). Not only were some of those pressures absent for low SEP participants, there were additional influences within the social context which were pro-smoking.ConclusionsIn order to narrow the health inequality gap associated with smoking, it is important to take account of the more pro-smoking social context experienced by low SEP smokers. Suggestions are made regarding social marketing campaigns, support for quit assistance and approaches to the regulation of smoking which may assist in minimising smoking-related health inequality.

Improving medication adherence in chronic obstructive pulmonary disease: a systematic review

Adherence to medication among individuals with chronic obstructive pulmonary disease (COPD) is suboptimal and has negative impacts on survival and health care costs. No systematic review has examined the effectiveness of interventions designed to improve medication adherence. Electronic databases Medline and Cochrane were searched using a combination of MeSH and keywords. Eligible studies were interventions with a primary or secondary aim to improve medication adherence among individuals with COPD published in English. Included studies were assessed for methodological quality using the Effective Practice and Organisation of Care (EPOC) criteria. Of the 1,186 papers identified, seven studies met inclusion criteria. Methodological quality of the studies was variable. Five studies identified effective interventions. Strategies included: brief counselling; monitoring and feedback about inhaler use through electronic medication delivery devices; and multi-component interventions consisting of self-management and care co-ordination delivered by pharmacists and primary care teams. Further research is needed to establish the most effective and cost effective interventions. Special attention should be given to increasing patient sample size and using a common measure of adherence to overcome methodological limitations. Interventions that involve caregivers and target the healthcare provider as well as the patient should be further explored.

Smoking care provision in hospitals: a review of prevalence

Hospitals are key settings for the provision of smoking cessation care. Limited data are available that describe the prevalence and type of such care delivered routinely in this setting. We reviewed studies conducted in hospitals and published between 1994 and 2005 that reported levels of smoking care delivery. This review describes the proportion of patients receiving, and the proportion of health professionals providing, various smoking cessation care practices. We used both descriptive and meta-analytic methods. According to the meta-analysis, smoking status was assessed in 60% of patients, 42% were advised or counseled to quit, 14% were provided with or advised to use nicotine replacement therapy (NRT), and 12% received referrals or follow-up. Significantly fewer patients received follow-up or referrals than were assessed for smoking status or received advice or counseling to quit. Some 81% of health professionals reported they assessed smoking status, 70% advised or counseled patients to quit, 13% provided NRT or advised its use, and 39% provided referrals or follow-up. Significantly fewer health professionals advised or prescribed NRT than assessed smoking status or advised or counseled patients to quit. Statistical heterogeneity was indicated for all smoking care practices. Levels of smoking cessation care are less than optimal in hospitals, and the levels of some important care practices are particularly low. Future research should identify effective methods for increasing smoking care provision in this setting. In addition, standardized measures of smoking care should be developed. Hospital organizations should enhance and continue to monitor their delivery of smoking care.

Determinants of career choices among women and men medical students and interns

Summary. Women continue to be poorly represented in medical specialties other than general practice. A cross‐sectional design was used to explore the development of career plans as medical training progressed; men and women students were compared in their first (n= 316), final (n= 295) and intern (n= 292) years. Women at each stage of training were significantly more likely to choose general practice as the field in which they were most likely to practise. There was little evidence that these differences were influenced by experience during training: women were as likely to choose general practice in first year as in the intern year. The most important determinant of career choice appeared to be the flexibility of training and of practice of medicine: variables such as the opportunity for part‐time training, flexible working hours and part‐time practice were important determinants of career choice and were of more importance to women than to men. The study also found high rates of discrimination or harassment reported by women medical students and interns. The results indicate the need for continued debate about these issues within medicine and the development of more flexible styles of medical training and practice.

Proactive Telephone Counseling for Smoking Cessation: Meta-analyses by Recruitment Channel and Methodological Quality

BACKGROUND Systematic reviews demonstrated that proactive telephone counseling increases smoking cessation rates. However, these reviews did not differentiate studies by recruitment channel, did not adequately assess methodological quality, and combined different measures of abstinence. METHODS Twenty-four randomized controlled trials published before December 31, 2008, included seven of active recruitment, 16 of passive recruitment, and one of mixed recruitment. We rated methodological quality on selection bias, study design, confounders, blinding, data collection methods, withdrawals, and dropouts, according to the Quality Assessment Tool for Quantitative Studies. We conducted random effects meta-analysis to pool the results according to abstinence type and follow-up time for studies overall and segregated by recruitment channel, and methodological quality. The level of statistical heterogeneity was quantified by I(2). All statistical tests were two-sided. RESULTS Methodological quality ratings indicated two strong, 10 moderate, and 12 weak studies. Overall, compared with self-help materials or no intervention control groups, proactive telephone counseling had a statistically significantly greater effect on point prevalence abstinence (nonsmoking at follow-up or abstinent for at least 24 hours, 7 days before follow-up) at 6-9 months (relative risk [RR] = 1.26, 95% confidence interval [CI] = 1.11 to 1.43, P < .001, I(2) = 21.4%) but not at 12-15 months after recruitment. This pattern also emerged when studies were segregated by recruitment channel (active, passive) or methodological quality (strong/moderate, weak). Overall, the positive effect on prolonged/continuous abstinence (abstinent for 3 months or longer before follow-up) was also statistically significantly greater at 6-9 months (RR = 1.58, CI = 1.26 to 1.98, P < .001, I(2) = 49.1%) and 12-18 months after recruitment (RR = 1.40, CI = 1.23 to 1.60, P < .001, I(2) = 18.5%). CONCLUSIONS With the exception of point prevalence abstinence in the long term, these data support previous results showing that proactive telephone counseling has a positive impact on smoking cessation. Proactive telephone counseling increased prolonged/continuous abstinence long term for both actively and passively recruited smokers.

Increasing smoking cessation care provision in hospitals: A meta-analysis of intervention effect

INTRODUCTION Levels of hospital smoking cessation care are less than optimal. This study aimed to synthesize the evidence regarding the effectiveness of interventions in increasing smoking cessation care provision in hospitals. METHODS A review identified relevant studies published between 1994 and 2006. A description of studies, including methodological quality, was undertaken. Intervention effectiveness in increasing smoking cessation care practices was examined for controlled studies using meta-analysis. Care practices examined were assessment of smoking status; advice to quit; counseling or assistance to quit; advising, offering, or providing nicotine replacement therapy (NRT); and follow-up or referral. RESULTS Of the 25 identified studies, 18 were U.S. based and in inpatient settings. Of the 10 controlled trials, 4 addressed cardiac patients, 5 measured one smoking cessation care practice, and 9 implemented multistrategic interventions (e.g., combining educational meetings with reminders and written resources). The methodology described in these studies was generally of poor quality. Meta-analysis of controlled trials demonstrated a significant intervention effect for provision of assistance and counseling to quit (pooled risk difference = 16.6, CI = 4.9-28.3) but not for assessment of smoking status, advice to quit, or the provision or discussion of NRT. Statistical heterogeneity was indicated for all smoking cessation care practices. An insufficient number of studies precluded the use of meta-analysis for follow-up or referral for further assistance. DISCUSSION Interventions can be effective in increasing the routine provision of hospital smoking cessation care. Future research should use more rigorous study design, examine a broader range of smoking cessation care practices, and focus on hospital-wide intervention implementation.

Has the investment in public cancer education delivered observable changes in knowledge over the past 10 years

During the 1990s, Western countries, such as Australia, directed substantial funds toward public cancer education. An important indicator of whether this investment has been worthwhile is a shift over time in the proportion of the population who have accurate knowledge regarding cancer.

Evaluation of systems-oriented public health interventions: alternative research designs.

The need to provide sound evidence of the costs and benefits of real-world public health interventions has driven advances in the development and analysis of designs other than the controlled trial in which individuals are randomized to an experimental condition. Attention to methodological quality is of critical importance to ensure that any evaluation can accurately answer three fundamental questions: (a) Has a change occurred, (b) did the change occur as a result of the intervention, and (c) is the degree of change significant? A range of alternatives to the individual randomized controlled trial (RCT) can be used for evaluating such interventions, including the cluster RCT, stepped wedge design, interrupted time series, multiple baseline, and controlled prepost designs. The key features and complexities associated with each of these designs are explored.
