Brief summary
Smoking throughout pregnancy causes irreversible harm to both the mother and fetus. Although smoking rates have declined considerably, rates of smoking during pregnancy remain steady among socioeconomically disadvantaged populations. The Northern Area Local Health Network (NALHN) serves a substantially disadvantaged population with approximately 1 in 4 women smoking during pregnancy. Standard practice at NALHN is to refer women to the Quitline, yet it is widely acknowledged by women and health professionals that women rarely engage with the service (Fletcher et al. 2021, unpublished). Studies exploring the use of carbon monoxide (CO) monitoring in antenatal care to encourage smoking cessation have shown promising results. This project will explore the feasibility and acceptability of using CO monitoring in antenatal care at the NALHN antenatal services.
Interventions
This study will explore the feasibility and acceptability of using CO monitoring during pregnancy to encourage smoking cessation.
CO monitoring
Women who smoke in pregnancy will be asked to breathe into a calibrated CO monitor (PiCO Baby Smokerlyzer). CO breath analysis involves the person taking a breath and holding it for 15 seconds, then blowing into a disposable mouthpiece attached to the CO monitor to empty their lungs. CO readings are then displayed on the monitor for both the mother and
This study will explore the feasibility and acceptability of using CO monitoring during pregnancy to encourage smoking cessation. CO monitoring Women who smoke in pregnancy will be asked to breathe into a calibrated CO monitor (PiCO Baby Smokerlyzer). CO breath analysis involves the person taking a breath and holding it for 15 seconds, then blowing into a disposable mouthpiece attached to the CO monitor to empty their lungs. CO readings are then displayed on the monitor for both the mother and the fetus. The CO level will be explained to the participant with a poster (visual aid) provided by the manufacturer, which shows maternal and fetal CO content of blood. CO readings will be documented and researchers will then qualitatively discuss use of the monitor using a semi-structured interview schedule. The mode of delivery will be 30 mins face-to-face with a midwifery-trained researcher in the hospital setting where antenatal care is provided. The researcher will then discuss with participants and provide information on supports available to women. This will take two forms. The first refers to mental health services available to women at the hospital and in the community. The second refers to smoking cessation strategies and supports available to pregnant women. Both will be provided to all participants. Smoking cessation strategies for use in pregnancy include nicotine replacement therapy (NRT), smartphone applications, 'cold turkey' and counselling supports. Four weeks later researchers will meet with participants at a follow up appointment. This follow up will allow women time to reflect on the CO monitoring previously conducted and to ask whether they had changed their smoking behaviour. At this appointment participants will be asked to use the CO monitor for a second time and answer follow up qualitative questions, again using a semi-structured interview schedule. The mode of delivery will again be 30 minutes of face-to-face contact with a trained researcher in the hospital where antenatal care is provided, a community centre or the participants home. Thus, there are 2 points of intervention.
