Clearing the air: improving smoke-free policy compliance at the national oncology hospital in Armenia

Effects of Electronic Cigarettes on Indoor Air Quality and Health

With the rapid increase in electronic cigarette (e-cig) users worldwide, secondhand exposure to e-cig aerosols has become a serious public health concern. We summarize the evidence on the effects of e-cigs on indoor air quality, chemical compositions of mainstream and secondhand e-cig aerosols, and associated respiratory and cardiovascular effects. The use of e-cigs in indoor environments leads to high levels of fine and ultrafine particles similar to tobacco cigarettes (t-cigs). Concentrations of chemical compounds in e-cig aerosols are generally lower than those in t-cig smoke, but a substantial amount of vaporized propylene glycol, vegetable glycerin, nicotine, and toxic substances, such as aldehydes and heavy metals, has been reported. Exposures to mainstream e-cig aerosols have biologic effects but only limited evidence shows adverse respiratory and cardiovascular effects in humans. Long-term studies are needed to better understand the dosimetry and health effects of exposures to secondhand e-cig aerosols.

What Are the Perceptions, Experiences, and Behaviors of Health Care Providers After Implementation of a Comprehensive Smoke-Free Hospital Policy?

The aim of this study was to explore the perceptions, experiences, and behaviors of health care providers (HCPs) after the implementation of a comprehensive smoke-free policy. This qualitative descriptive study, using semi-structured interviews, was conducted with 28 HCPs working in a Canadian hospital. Four overarching themes emerged from the analysis including (a) greater support for tobacco reduction, (b) enhanced patient care and interactions, (c) improved staff morale, and (d) some barriers still exist. The main findings suggest a comprehensive smoke-free hospital environment can strengthen the tobacco-free workplace culture within a hospital setting among HCPs where support for tobacco reduction is amplified, patient care and interactions regarding tobacco dependence are improved, and staff morale is enhanced. While there are still some challenging barriers as well as opportunities for improvements, the implementation of a comprehensive smoke-free policy heightened the call-to-action among HCPs to take a more active role in tobacco reduction.
