This paper draws attention to how using a simple and low-cost surveillance inquiry may help focus on the use of scarce inspection resources to improve compliance with the law in the hospitality sector. We conducted a cross-sectional assessment of second-hand smoke exposure in night entertainment venues in Santiago, Chile, by measuring particulate matter of less than 2.5μm (PM2.5). Smoking where prohibited by law was observed in 36% of the venues visited. Venues where smoking was spotted at the time of the observation had a median PM2.5 concentration 13 times higher than background concentration on the street. The study shows that a targeted approach for inspection to find pockets of venues with suboptimal compliance is feasible and affordable.3 p.application/pdfengcc by-nc-nd (c) Peruga, Armando et al, 2021http://creativecommons.org/licenses/by-nc-nd/3.0/es/Hàbit de fumarHospitalsSmokingHospitalsinfo:eu-repo/semantics/publishedVersion2021-08-05info:eu-repo/semantics/openAccess
