Plain English Summary
Background and study aims
Secondhand smoke exposure (SHSe), occurs when tobacco products are burned and then inhaled by those in the vicinity. There is no safe level of exposure and globally 1.2 million deaths are attributed to SHSe annually. Childhood SHSe has been causally linked with a number of childhood illnesses including respiratory tract infections and meningitis as well as associated with some childhood cancers. 39% of children in England whose parents smoke are regularly exposed to SHS in the home. Children who grow up with smokers are over twice as likely to become smokers themselves and regular smokers double their risk of premature death. The most effective way to reduce children’s SHSe is to support their parents to quit smoking. However, for parents who cannot or are unable to quit, there is a need to support families to change their smoking behaviours (such as to support them to make their homes smoke-free) to reduce the harm to children living in their household. Paediatric healthcare visits, such as an admission to hospital, may provide an ideal teachable moment (events or circumstances which can lead individuals to positive behaviour change) to initiate and/or deliver a SHS intervention to support families to reduce their children’s exposure to SHS. At the moment, little is known about the views of parents or healthcare professionals (HCPs) about the potential of using hospital presentation as an opportunity to initiate and/or deliver an intervention to reduce children’s SHSe.
The determinants of behaviour (capability, opportunity and motivation) will be explored from the perspective of the parents to gain an understanding of how the teachable moment can be capitalised on to instigate sustained behaviour change, as well as, from the perspective of the HCPs and how they can use the hospital setting to initiate and/or deliver SHS harm reduction messages to parents. The acceptability of approaches, content, and the delivery of interventions around SHS harm reduction will be explored from the perspective of all stakeholders. The study results will be used to guide the development of a future intervention to reduce SHS-related harms in childhood
Who can participate?
1. Parents/carers (aged >18 years) who have smoked in the home within the last 5 years and have presented with their child at Birmingham Children’s Hospital (BCH)
2. HCPs who have worked with parents and their children within the last 5 years at BCH
What does the study involve?
In order to understand the views of stakeholders on a secondary care initiated and/or delivered intervention to reduce children’s exposure to SHS a programme of research will be carried out including:
Discussions with up to 20 parents/carers who have smoked in the home within the last 5 years and present at BCH with their child to understand their views on using the hospital visit as an opportunity to support parents to change their home smoking behaviours.
Discussions with up to 25 HCPs who have worked with parents and children who are exposed to SHS at BCH within the last 5 years to understand their views on using the hospital visit as an opportunity to support parents to change their home smoking behaviours
What are the possible benefits and risks of participating?
This research may not directly benefit participants, but what they tell us may help us to better understand the perspectives of parents/carers who smoke (or have previously smoked) at home. We hope that we will be able use what we learn to explore ways the hospital might support families to change their home smoking behaviours.
There are no physical risks to taking part in this study. We do not anticipate that the interview/ discussion group will cause distress.

A qualitative study to explore stakeholder views on children’s secondhand smoke interventions within hospitals
To explore key stakeholder views and behaviour change opportunities for a hospital-based intervention around supporting parents to change their home smoking behaviours to reduce children’s exposure to SHS, informed by the COM-B model. This overarching aim will be addressed in two work packages (WP).
Work package 1a aims to use the COM-B model to explore parent/carer knowledge, attitudes, perceptions and acceptability of a hospital-based intervention to change their home smoking behaviours
a. To explore parental knowledge of SHS and experience of hospital contact around smoking behaviour.
b. To identify parental attitudes and perceptions towards receiving a hospital-based intervention to support them to change their home smoking behaviours.
c. To explore the perceived acceptability among parents of receiving a hospital-based intervention to support them to change their home smoking behaviours.
Work package 1b aims to use the COM-B model to explore healthcare professionals’ knowledge, attitudes, perceptions and acceptability of a hospital-based intervention to support parents to change their home smoking behaviours.
a. To explore HCPs knowledge of intervening around parent home smoking behaviours.
b. To identify HCP attitudes and perceptions towards a parent hospital-based intervention to change their home smoking behaviours.
c. To explore the perceived acceptability among HCPs for a parent hospital-based intervention to change their home smoking behaviours.

Patient information sheet
Not available in web format, please use contact details to request a copy of the different participant information leaflets used in this study
Work package 1a
Informed by the COM-B model, we will undertake qualitative semi-structured interviews and/or discussion groups with parents/carers who have attended BCH with their child and have smoked in the home in the last 5 years.
Whilst semi-structured and informed by WP discussion guides, interviews/discussion groups will be conducted in a participant-focused manner allowing experiences and views important to participants to emerge naturally. The overall aim of the discussions is to explore knowledge, attitudes and perceptions towards receiving a hospital-based intervention to support them to change their home smoking behaviours, as well as, whether they perceive this to be an acceptable time and setting for such an intervention.
Interviews/discussion groups will be digitally audio recorded, transcribed and then anonymised and checked for accuracy. Participants will be identified via advertising at the hospital site, social media such as Twitter and Facebook, the Trust website and via word of mouth (self-selected). Brief participant information leaflets will be available at reception desks and sent with appointment letters. Potential participants will always be approached by a member of their child’s usual care team in the first instance.
Work package 1b
Informed by the COM-B model, we will undertake qualitative semi-structured interviews and/or discussion groups with HCPs who work at BCH (or previously within the last 5 years).
Whilst semi-structured and informed by WP discussion guides, interviews/discussion groups will be conducted in a participant-focused manner allowing experiences and views important to participants to emerge naturally. The overall aim of the discussions is to explore their knowledge, attitudes and perceptions towards initiating and/or delivering an intervention to reduce parents’ home smoking behaviours as well as whether they perceive this to be an acceptable time and setting for an intervention.
Interviews/discussion groups will be digitally audio recorded, transcribed and then anonymised and checked for accuracy. HCPs at BCH will be contacted directly about the study through personal and professional networks of the research team members. This study will be advertised via posters in the hospital (i.e. staff rooms), on social media for example via Facebook and Twitter, the Trust intranet, and in email newsletters
Primary outcome measure
An understanding of stakeholder attitudes, beliefs and perceptions of a secondary care initiated and/or delivered intervention to reduce children’s exposure to secondhand smoke. Data (with the exception of a non-validated demographic questionnaire that will allow us to describe the sample of participants) will be qualitative in nature including field notes, audio files and transcripts. Participants will take part in a one off interview or discussion group lasting between 60 and 90 minutes.
