RESUMEN
OBJECTIVES: This study aimed to examine changes in the proportion of smokers who were advised to quit smoking by health professionals as part of routine consultations or interactions with their patients between 2008 and 2019. STUDY DESIGN: Serial cross-sectional study. METHODS: Data from two nationally representative cross-sectional surveys were used to examine changes over time in the proportions of smokers who were seen by a doctor or other healthcare provider for any health concern and were advised to quit smoking ('Advice_HP'). An additional dichotomous variable ('AdviceAccess_HP') was created and included smokers who were not seen by a doctor or other healthcare provider in the past 12 months in the 'no advice' received category. Crude and adjusted absolute differences in prevalence rates of smokers who were advised to quit smoking by health professionals as part of routine consultations or interactions with their patients between 2008 and 2019 were evaluated using a generalised linear model. RESULTS: The proportion of smokers who were seen by a health professional for any health concern increased from 58.8% in 2008 to 88.7% in 2019. The proportion of 'AdviceAccess_HP' increased from 33.6% in 2008 to 45.2% in 2019; however, the proportion of 'Advice_HP' decreased from 57.1% in 2008 to 51.0% in 2019. After adjustment for sociodemographic and smoking behaviour characteristics, differences remained virtually unchanged. In 2019, health professionals missed the opportunity to provide around 10 million smokers with brief advice to stop smoking. CONCLUSIONS: Monitoring the actions needed to encourage smoking cessation is critical for achieving the United Nations sustainable development goals. Primary healthcare workers should serve as role models for patients and provide brief advice that increases the likelihood of successfully quitting tobacco use, particularly in low- and middle-income countries.
