Legislative smoking bans for reducing secondhand smoke exposure ...

Pell 2008 (Continued)
Outcomes Self-reported exposure to SHS as defined by the number of hrs per wk in the home, work, “bars, pubs or clubs”,
“cars, buses or trains”, other public places, other people’s homes and “all locations”.
Number of hospital admissions and relative risk reduction (95% CI) of acute coronary syndrome (ACS) by age,
gender and smoking status. Analysis of ACS in men 55 yrs, in women < 65 yrs and > 65 yrs and for
all patients with ACS. Acute coronary syndrome (ICD-10) defined by a detectable level of cardiac troponin after
emergency admission for chest pain.
Self-reported smoking status
Biochemical verification: Yes; smoking status and exposure to SHS as measured by geometric mean serum cotinine
ng/ml.
Notes Nonsmokers defined as those with 12ng/ml serum cotinine or less. Limit of detection 0.1ng/ml.
Pell 2009
Methods Country: Scotland
Setting: Scottish Acute Hospital Population
Design: Pre and post-ban tests. Prospective cohort study. Data was collected pre and post ban in Scotlandon consecutive
patients who were non smokers admitted with ACS to nine Scottish acute hospitals. Follow-up data were
obtained from routine hospital admissions and death databases. Chi 2 tests for trend and logistic regression, both
univariate and multivariate.
Participants Consecutive admissions who were non smokers admitted with ACS to nine Scottish acute hospitals from May 2005
to March 2007
Baseline:1261
Follow up: 30 days post admission
50 had died and 35 had a non fatal MI.
Interventions Smokefree legislation (Smoking, Health and Social Care (Scotland) Bill) implemented on 26 th March, 2006 prohibiting
smoking in indoor workplaces, including bars, restaurants and cafes.
Outcomes Cotinine levels. All cause death, cardiovascular death or readmission for a principal diagnosis of AMI.
Biochemical verification: Yes. Urinary cotinine measured exposure to SHS.
Notes
Sargent 2004
Methods Country: USA
Setting: Helena, Montana
Design: Observational study, cross-sectional surveys, pre and post-ban tests. Analysis: Analysis of admission admitted
for AMI for people living in and outside Helenausing Poisson analysis.
Participants Total sample: 304 admissions living in and outside Helena
During ban period: 42 admissions
Interventions Local law in place in Helena, Montana from June-Nov 2002 which banned smoking in workplaces and public places.
