Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Nicotine replacement therapy (patch 21mg) replaced daily, until discharge from hospital. Medication adherence will be monitored using hospital medication chart.
+ Brief Intervention - A formal brief counselling intervention consisting of a one-off session discussing smoking cessation strategies following the GP QUIT advice program. Session will be one-off 15-30 minute session at time of readiness for ICU discharge. Intervention administered by a member of the research team.
Smoking cessation strategies follow the Ask, Advice, Help model, and how patients can refer themselves to QUIT, and how nicotine replacment therapy can assist with withdrawal symptoms.

Efficacy
Statistical methods / analysis
Based on estimates that 30% of smokers discharged from ICU will use QUIT services, and expectation that intervention will increase this to 60%, with an alpha 0.05, beta 0.2 and power 0.8, gives a sample size of 84. To allow for loss to follow-up – 100 patients. Primary outcome of interest is self referral to QUIT.

Prospective subgroups for analysis: Post cardiothoracic surgery admission, exacerbation of obstructive airways disease as admitting diagnosis (COPD/asthma), and mental illness.


Descriptive analysis of baseline characteristics, comparison of groups using chi2 or parametric testing where appropriate.

Summary
Brief summary
Despite a dramatic decline in tobacco smoking prevalence, current smoking rates have plateaued and smoking remains the leading cause of preventable diseases and death in Australia. Smoking rates in ICU patients are higher than the general population, offering an opportunity for intervention, especially as there is good evidence that many smokers do consider cessation following an ICU admission. Thus surviving an ICU admission potentially provides a unique opportunity to promote long-term smoking cessation.

Whilst smoking cessation interventions have been evaluated in hospital settings, the optimal intervention remains unclear and no studies looking at combination nicotine replacement therapy (NRT) and counselling have been performed specifically in ICU survivors. Our goal is to conduct a randomized controlled trial comparing standard care (ad hoc advice to patients and NRT) to a formal brief counselling intervention in addition to protocolized NRT. The aim is to improve smoking cessation rates in ICU survivors and thus improve their morbidity and mortality.
