Objective: To describe the research methods and baseline sample of the Talking About The Smokes (TATS) project. Design: The TATS project is a collaboration between research institutions and Aboriginal community‐controlled health services (ACCHSs) and their state and national representative bodies. It is one of the studies within the International Tobacco Control Policy Evaluation Project, enabling national and international comparisons. It includes a prospective longitudinal study of Aboriginal and Torres Strait Islander smokers and recent ex‐smokers; a survey of non‐smokers; repeated cross‐sectional surveys of ACCHS staff; and descriptions of the tobacco policies and practices at the ACCHSs. Community members completed face‐to‐face surveys; staff completed surveys on paper or online. We compared potential biases and the distribution of variables common to the main community baseline sample and unweighted and weighted results of the 2008 National Aboriginal and Torres Strait Islander Social Survey (NATSISS). The baseline survey (Wave 1) was conducted between April 2012 and October 2013. Setting and participants: 2522 Aboriginal and Torres Strait Islander people in 35 locations (the communities served by 34 ACCHSs and one community in the Torres Strait), and 645 staff in the ACCHSs. Main outcome measures: Sociodemographic and general health indicators, smoking status, number of cigarettes smoked per day and quit attempts. Results: The main community baseline sample closely matched the distribution of the Aboriginal and Torres Strait Islander population in the weighted NATSISS by age, sex, jurisdiction and remoteness. There were inconsistent differences in some sociodemographic factors between our sample and the NATSISS: our sample had higher proportions of unemployed people, but also higher proportions who had completed Year 12 and who lived in more advantaged areas. In both surveys, similar percentages of smokers reported having attempted to quit in the past year, and daily smokers reported similar numbers of cigarettes smoked per day. Conclusion: The TATS project provides a detailed and nationally representative description of Aboriginal and Torres Strait Islander smoking behaviour, attitudes, knowledge and exposure to tobacco control activities and policies, and their association with quitting.

Objective: To describe the Talking About The Smokes (TATS) project according to the World Health Organization guiding principles for conducting community‐based participatory research (PR) involving indigenous peoples, to assist others planning large‐scale PR projects. Design, setting and participants: The TATS project was initiated in Australia in 2010 as part of the International Tobacco Control Policy Evaluation Project, and surveyed a representative sample of 2522 Aboriginal and Torres Strait Islander adults to assess the impact of tobacco control policies. The PR process of the TATS project, which aimed to build partnerships to create equitable conditions for knowledge production, was mapped and summarised onto a framework adapted from the WHO principles. Main outcome measures: Processes describing consultation and approval, partnerships and research agreements, communication, funding, ethics and consent, data and benefits of the research. Results: The TATS project involved baseline and follow‐up surveys conducted in 34 Aboriginal community‐controlled health services and one Torres Strait community. Consistent with the WHO PR principles, the TATS project built on community priorities and strengths through strategic partnerships from project inception, and demonstrated the value of research agreements and trusting relationships to foster shared decision making, capacity building and a commitment to Indigenous data ownership. Conclusions: Community‐based PR methodology, by definition, needs adaptation to local settings and priorities. The TATS project demonstrates that large‐scale research can be participatory, with strong Indigenous community engagement and benefits.

Objectives: To describe past attempts to quit smoking in a national sample of Aboriginal and Torres Strait Islander people, and to compare their quitting activity with that in the general Australian population. Design, setting and participants: The Talking About The Smokes (TATS) project used a quota sampling design to recruit participants from communities served by 34 Aboriginal community‐controlled health services and one community in the Torres Strait. We surveyed 1643 smokers and 78 recent quitters between April 2012 and October 2013. Baseline results for daily smokers (n = 1392) are compared with results for daily smokers (n = 1655) from Waves 5 to 8.5 (2006–2012) of the Australian International Tobacco Control Policy Evaluation Project (ITC Project). Main outcome measures: Ever having tried to quit, tried to quit in the past year, sustained a quit attempt for 1 month or more. Results: Compared with the general population, a smaller proportion of Aboriginal and Torres Strait Islander daily smokers had ever tried to quit (TATS, 69% v ITC, 81.4%), but attempts to quit within the past year were similar (TATS, 48% v ITC, 45.7%). More Aboriginal and Torres Strait Islander daily smokers than those in the general population reported sustaining past quit attempts for short periods only. Aboriginal and Torres Strait Islander smokers whose local health services had tobacco control resources were more likely to have tried to quit, whereas men and people who perceived they had experienced racism in the past year were less likely. Younger smokers, those who had gone without essentials due to money spent on smoking, and those who were often unable to afford cigarettes were more likely to have tried to quit in the past year, but less likely to have ever sustained an attempt for 1 month or more. Smokers who were unemployed, those who had not completed Year 12 and those from remote areas were also less likely to sustain a quit attempt. Conclusions: Existing comprehensive tobacco control programs appear to be motivating Aboriginal and Torres Strait Islander smokers to quit but do not appear to overcome challenges in sustaining quit attempts, especially for more disadvantaged smokers and those from remote areas.

BackgroundRe-contouring of structures on consecutive planning computed tomography (CT) images for patients that exhibit anatomical changes is elaborate and may negatively impact the turn-around time if this is required for many patients. This study was therefore initiated to validate the accuracy and usefulness of automatic contour propagation for head and neck cancer patients using SmartAdapt® which is the deformable image registration (DIR) application in Varian’s Eclipse™ treatment planning system.MethodsCT images of eight head and neck cancer patients with multiple planning CTs were registered using SmartAdapt®. The contoured structures of target volumes and OARs of the primary planning CT were deformed accordingly and subsequently compared with a reference structure set being either: 1) a structure set independently contoured by the treating Radiation Oncologist (RO), or 2) the DIR-generated structure set after being reviewed and modified by the RO.ResultsApplication of DIR offered a considerable time saving for ROs in delineation of structures on CTs that were acquired mid-treatment. Quantitative analysis showed that 84% of the volume of the DIR-generated structures overlapped with the independently re-contoured structures, while 94% of the volume overlapped with the DIR-generated structures after review by the RO. This apparent intra-observer variation was further investigated resulting in the identification of several causes. Qualitative analysis showed that 92% of the DIR-generated structures either need no or only minor modification during RO reviews.ConclusionsSmartAdapt is a powerful tool with sufficient accuracy that saves considerable time in re-contouring structures on re-CTs. However, careful review of the DIR-generated structures is mandatory, in particular in areas where tumour regression plays a role.

Objective: To describe factors that predict wanting to quit smoking in a national sample of Aboriginal and Torres Strait Islander people. Design, setting and participants: The Talking About The Smokes (TATS) project used a quota sampling design to recruit participants from communities served by 34 Aboriginal community‐controlled health services and one community in the Torres Strait. Baseline survey data were collected from 1643 current smokers between April 2012 and October 2013. Main outcome measure: Wanting to quit smoking. Results: More than two‐thirds of smokers (70%) said they want to quit. Many factors were associated with wanting to quit, including past quitting activity. Interest in quitting was lower among men and smokers from economically disadvantaged areas, but there was no difference by age, remoteness or other measures of economic disadvantage. Attitudes and beliefs negatively associated with wanting to quit included enjoying smoking and believing quitting to be very difficult, and those positively associated included regretting ever starting to smoke, perceiving that local Aboriginal and Torres Strait Islander community leaders disapprove of smoking, believing non‐smokers set a good example to children, worrying about future smoking‐related health effects and believing quitting to be beneficial. Reporting support from family and friends was predictive of wanting to quit, but factors related to smoking in the social network were not. Associations with health and wellbeing were mixed. While most tobacco control policy exposure variables were positively associated with wanting to quit, two — receiving advice to quit from a health professional, and recall of targeted anti‐tobacco advertising — appeared to have an effect that extended beyond influencing relevant attitudes and beliefs. Conclusion: Interest in quitting among Aboriginal and Torres Strait Islander smokers appears to be influenced by a broad range of factors, highlighting the importance of taking a comprehensive approach to tobacco control. Advice from health professionals and targeted advertising appear to be important intervention strategies.
