Impact of tobacco control policies in hospitals: Evaluation of a national smoke-free campus ban in Spain

Abstract

Introduction

On January 2, 2011, the Spanish government passed a new smoking law that banned smoking in hospital campuses. The objective of this study was to evaluate the implementation of smoke-free campuses in the hospitals of Catalonia based on both airborne particulate matter and observational data.

Methods

This cross-sectional study included the hospitals registered in the Catalan Network of Smoke-free Hospitals. We measured the concentration of particulate matter < 2.5 µm in μg/m ³ at different locations, both indoors and outdoors before (2009) and after (2011) the implementation of the tobacco law. During 2011, we also assessed smoke-free zone signage and indications of smoking in the outdoor areas of hospital campuses.

Results

The overall median particulate matter < 2.5 µm concentration fell from 12.22 μg/m ³ (7.80–19.76 μg/m ³) in 2009 to 7.80 μg/m ³ (4.68–11.96 μg/m ³) in 2011. The smoke-free zone signage within the campus was moderately implemented after the legislation in most hospitals, and 55% of hospitals exhibited no indications of tobacco consumption around the grounds.

Conclusions

After the law, particulate matter < 2.5 µm concentrations were much below the values obtained before the law and below the annual guideline value recommended by the World Health Organization for outdoor settings (10 μg/m ³). Our data showed the feasibility of implementing a smoke-free campus ban and its positive effects.

Highlights

• •

  We evaluate the implementation of smoke-free campuses before and after new smoke-free legislation.

• •

  We measured PM _2.5 concentrations and registered smoke-free zone signage and indications of smoking in the outdoor areas.

• •

  Median PM _2.5 concentration significantly fell from 12.22 μg/m ³ before the law to 7.80 μg/m ³ after the law.

• •

  Smoke-free campuses were highly implemented in most of the hospitals.
