Abstract

BACKGROUND: Pregnancy is an opportunity for health providers to support women to stop smoking.
OBJECTIVES: Identify the pooled prevalence for health providers in providing components of smoking cessation care to women who smoke during pregnancy.
DESIGN: A systematic review synthesising original articles that reported on (1) prevalence of health providers' performing the 5As ('Ask', 'Advise', 'Assess', 'Assist', 'Arrange'), prescribing nicotine replacement therapy (NRT) and (2) factors associated with smoking cessation care.
DATA SOURCES: MEDLINE, EMBASE, CINAHL and PsycINFO databases searched using 'smoking', 'pregnancy' and 'health provider practices'.
ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Studies included any design except interventions (self-report, audit, observed consultations and women's reports), in English, with no date restriction, up to June 2017.
PARTICIPANTS: Health providers of any profession.
DATA EXTRACTION, APPRAISAL AND ANALYSIS: Data were extracted, then appraised with the Hawker tool. Meta-analyses pooled percentages for performing each of the 5As and prescribing NRT, using, for example, 'often/always' and 'always/all'. Meta-regressions were performed of 5As for 'often/always'.
RESULTS: Of 3933 papers, 54 were included (n=29 225 participants): 33 for meta-analysis. Health providers included general practitioners, obstetricians, midwives and others from 10 countries. Pooled percentages of studies reporting practices 'often/always' were: 'Ask' (n=9) 91.6% (95% CI 88.2% to 95%); 'Advise' (n=7) 90% (95% CI 72.5% to 99.3%), 'Assess' (n=3) 79.2% (95% CI 76.5% to 81.8%), 'Assist (cessation support)' (n=5) 59.1% (95% CI 56% to 62.2%), 'Arrange (referral)' (n=6) 33.3% (95% CI 20.4% to 46.2%) and 'prescribing NRT' (n=6) 25.4% (95% CI 12.8% to 38%). Heterogeneity (I) was 95.9%-99.1%. Meta-regressions for 'Arrange' were significant for year (p=0.013) and country (p=0.037).
CONCLUSIONS: Health providers 'Ask', 'Advise' and 'Assess' most pregnant women about smoking. 'Assist', 'Arrange' and 'prescribing NRT' are reported at lower rates: strategies to improve these should be considered.
