Overview • Options for evaluating smoke-free policies • Focus on five key outcomes • Public support • Compliance • Air quality • Employee health • Economic impact • Factors to consider in selecting among studies • Case studies
Measuring Public Support • These studies use surveys to assess the level of public support for a smoke-free law • Are you personally in favor, opposed to, or indifferent to the New York State law prohibiting smoking in all public and work places, including bars and restaurants? (NY ATS) • Useful before and after law passed • Before: Determine whether support is already high or if further public education is needed; document support • After: Document support; track changes in support over time
Observational Studies of Compliance • These studies involve visiting relevant venues (e.g., restaurants, bars, bowling alleys, casinos) to observe whether smoking is occurring • Observations of people smoking • Presence of smoke (seen or smelled) • Presence of “No Smoking” signs • Presence of ashtrays • Useful for measuring the extent of smoking before a law is put in place and for assessing compliance once a law takes effect
Air Quality Monitoring Studies • Assesses air quality in restaurants, bars, and other hospitality venues • Involves using a small, portable device to measure particulate matter suspended in air • Provides an objective measure of the presence of secondhand smoke (SHS) • Quantify air quality before and after a smoke-free law takes effect
Employee Health Studies • Assess SHS exposure and related health outcomes among nonsmoking employees of hospitality venues • Respiratory symptoms (e.g., coughing, wheezing) • Sensory symptoms (e.g., itchy eyes) • Other outcomes (e.g., lung function, NNAL levels) • Conducting baseline and follow-up studies can document changes in employee SHS exposure and related health outcomes • These findings have cost implications for employers
Economic Studies • Assess potential economic impact of smoke-free laws on restaurants, bars, and other hospitality venues • Draw on existing data on employment levels and taxable sales revenues from government sources • Track employment and sales before and after smoke-free law • Account for trends and seasonal patterns • Collect at least a year’s data after the law takes effect • If possible, compare trends to a control site • Long lag time before data become available
Selecting Among Studies—Factors to Consider • Assessing all five outcomes may not be necessary or feasible • Need to consider several factors • Stage of policy process (proposed, passed, implemented) • Key issues of interest to policymakers, the news media, the business community, and the public • Provisions of the smoke-free law (exemptions, phase-ins) • Resources for evaluation: funding, personnel, expertise, data
Stage: Policy Under Consideration • Three types of studies can be particularly helpful • Public support • Air quality in hospitality venues • Hospitality workers’ SHS exposure and related health outcomes • Taken together, these studies can make a compelling case for the need for SHS protection measures • They can also provide a baseline against which to measure progress
Stage: Policy Implemented • If baseline data collected • Collect follow-up data within 3 months and 12 months after the law takes effect • In absence of baseline data • Assess public support soon after the law takes effect to document support • Conduct observational or air quality studies to demonstrate compliance, identify problem areas, and/or illustrate the impact of gaps in law
Stakeholder Considerations • Is there public support for the law? • Will hospitality venues, other workplaces, and smokers comply with the law? • Will enforcement be expensive and time-consuming? • Will enforcement divert resources from more pressing needs? • Is the air quality in hospitality venues that allow smoking unhealthy? Did it improve after the law took effect? • Are nonsmoking hospitality employees exposed to SHS at work? Is this exposure affecting their health? • Is the law having a negative economic impact on hospitality venues?
Exemptions • Compromises that were made during the legislative process may have resulted in exemptions • Bar areas of restaurants, stand-alone bars, private clubs, casinos • Ventilation • Adults-only venues • Hardship exemptions • Long phase-ins
Exemptions • Evaluations can examine how such provisions impact a law’s effectiveness • Assess air quality and employee health in exempted or phased-in hospitality venues • Assess compliance
Resources • It is possible to carry out credible, useful studies with minimal resources, although with limitations • Refer to objective studies from other smoke-free jurisdictions • Use an existing survey that includes public support and compliance questions, or add questions to an existing survey • Assess compliance and air quality using volunteers
Case Studies • New York State • Laramie, Wyoming
