Health worker and patient views on implementation of smoking cessation in routine tuberculosis care

Böckmann M, Warsi S, Noor M, et al. Health worker and patient views on implementation of smoking cessation in routine tuberculosis care. NPJ primary care respiratory medicine. 2019;29(1): 34.Smoking worsens tuberculosis (TB) outcomes. Persons with TB who smoke can benefit from smoking cessation. We report findings of a multi-country qualitative process evaluation assessing barriers and facilitators to implementation of smoking cessation behaviour support in TB clinics in Bangladesh and Pakistan. We conducted semi-structured qualitative interviews at five case study clinics with 35 patients and 8 health workers over a period of 11 months (2017-2018) at different time points during the intervention implementation phase. Interviews were conducted by trained researchers in the native languages, audio-recorded, transcribed into English and analysed using a combined deductive-inductive approach guided by the Consolidated Framework for Implementation Research and Theoretical Domains Framework. All patients report willingness to quit smoking and recent quit attempts. Individuals' main motivations to quit are their health and the need to financially provide for a family. Behavioural regulation such as avoiding exposure to cigarettes and social influences from friends, family and colleagues are main themes of the interviews. Most male patients do not feel shy admitting to smoking, for the sole female patient interviewee stigma was an issue. Health workers report structural characteristics such as high workload and limited time per patient as primary barriers to offering behavioural support. Self-efficacy to discuss tobacco use with women varies by health worker. Systemic barriers to implementation such as staff workload and socio-cultural barriers to cessation like gender relations, stigma or social influences should be dealt with creatively to optimize the behaviour support for sustainability and scale-up

A Study into the Supply, Demand, Economic, Social and Institutional Aspects of Optimising Water Supply to Metropolitan Adelaide - Preliminary Research Findings: Summary Report from Project U2.2

In November 2012, the Goyder Institute for Water Research funded a research programme as a contribution to the building of a strong information base to inform debate on how best to underpin an efficient and sustainable water supply for metropolitan Adelaide, now and into the future, due to the likely impacts of a drying climate and population growth. Metropolitan Adelaide has multiple sources of water – surface water, groundwater, desalinated water, stormwater, roof or rain water, recycled water and the River Murray – that can be utilised and managed for supplying the city’s water needs. Using those sources in combination requires consideration of an appropriate balance across objectives such as supply security, economic cost, social preferences and environmental impacts

Cost-utility of cytisine for smoking cessation over and above behavioural support in people with newly diagnosed pulmonary tuberculosis:an economic evaluation of a multicentre randomised controlled trial

OBJECTIVES: To assess the cost-effectiveness of cytisine over and above brief behavioural support (BS) for smoking cessation among patients who are newly diagnosed with pulmonary tuberculosis (TB) in low-income and middle-income countries. DESIGN: An incremental cost-utility analysis was undertaken alongside a 12-month, double-blind, two-arm, individually randomised controlled trial from a public/voluntary healthcare sector perspective with the primary endpoint at 6 months post randomisation. SETTING: Seventeen subdistrict hospitals in Bangladesh and 15 secondary care hospitals in Pakistan. PARTICIPANTS: Adults (aged ≥18 years in Bangladesh and ≥15 years in Pakistan) with pulmonary TB diagnosed within the last 4 weeks who smoked tobacco daily (n=2472). INTERVENTIONS: Two brief BS sessions with a trained TB health worker were offered to all participants. Participants in the intervention arm (n=1239) were given cytisine (25-day course) while those in the control arm (n=1233) were given placebo. No significant difference was found between arms in 6-month abstinence. PRIMARY AND SECONDARY OUTCOME MEASURES: Costs of cytisine and BS sessions were estimated based on research team records. TB treatment costs were estimated based on TB registry records. Additional smoking cessation and healthcare costs and EQ-5D-5L data were collected at baseline, 6-month and 12-month follow-ups. Costs were presented in purchasing power parity (PPP) adjusted US dollars (US$). Quality-adjusted life years (QALYs) were derived from the EQ-5D-5L. Incremental total costs and incremental QALYs were estimated using regressions adjusting for respective baseline values and other baseline covariates. Uncertainty was assessed using bootstrapping. RESULTS: Mean total costs were PPP US$57.74 (95% CI 49.40 to 83.36) higher in the cytisine arm than in the placebo arm while the mean QALYs were -0.001 (95% CI -0.004 to 0.002) lower over 6 months. The cytisine arm was dominated by the placebo arm. CONCLUSIONS: Cytisine plus BS for smoking cessation among patients with TB was not cost-effective compared with placebo plus BS.
