Background:  It is unclear whether smoking increases the risk of COVID-19 hospitalisation. We first examined the association of smoking status with hospitalisation for COVID-19 compared with hospitalisation for other respiratory viral infections a year previous. Second, we examined the concordance between smoking status recorded on the electronic health record (EHR) and the contemporaneous medical notes.    Methods:  This case-control study enrolled adult patients (446 cases and 211 controls) at a single National Health Service trust in London, UK. The outcome variable was type of hospitalisation (COVID-19 vs. another respiratory virus a year previous). The exposure variable was smoking status (never/former/current smoker). Logistic regression analyses adjusted for age, sex, socioeconomic position and comorbidities were performed. The study protocol and analyses were pre-registered in April 2020 on the  Open Science Framework .    Results:  Current smokers had lower odds of being hospitalised with COVID-19 compared with other respiratory viruses a year previous (OR adj =0.55, 95% CI=0.31-0.96,  p =.04). There was no significant association among former smokers (OR adj =1.08, 95% CI=0.72-1.65,  p =.70). Smoking status recorded on the EHR (compared with the contemporaneous medical notes) was incorrectly recorded for 168 (79.6%) controls (χ 2 (3)=256.5,  p =&lt;0.001) and 60 cases (13.5%) (χ 2 (3)=34.2,  p =&lt;0.001).    Conclusions:  In a single UK hospital trust, current smokers had reduced odds of being hospitalised with COVID-19 compared with other respiratory viruses a year previous, although it is unclear whether this association is causal. Targeted post-discharge recording of smoking status may account for the greater EHR-medical notes concordance observed in cases compared with controls.
