Mean Implementation Scores, Spending per Smoker, and Treatment Reach Distributions for Tobacco Quitlines: United States and Canada, 2009

Variable	Mean	Median	Minimum	Maximum	SD
Mean implementation score for A-level efficacy practices	3.65	4.0	0	6	1.35
Mean implementation score for B-level efficacy practices	4.28	4.5	2.0	6	0.88
Mean implementation score for C-level efficacy practices	3.37	3.36	1.0	6	0.94
Mean implementation score for D-level efficacy practices	3.77	3.83	1.33	6	1.35
Mean implementation score for B-level reach practices	3.74	3.81	1.38	5.75	0.99
Mean implementation score for D-level reach practices	3.77	3.87	1.13	5.53	0.78
Spending per smoker on counseling and medications, $	3.11	1.63	0	19.89	4.09
Treatment reach, %	1.55	0.60	0.05	7.21	1.83

Note. A = practices that are effective, as indicated by findings of 1 or more meta-analyses or multiple high-quality single studies; B = practices with only 1 high-quality, or several inferior-quality (smaller sample size, single site, or small effect size), peer-reviewed journal articles and no meta-analyses documenting their effectiveness; C = practices that have been recommended by a reputable organization such as the Centers for Disease Control and Prevention but have no peer-reviewed journal articles documenting their effectiveness; D = practices that were not supported by any scientific evidence or recommendations from reputable organizations. Each quitline reported a level of implementation for each practice (ranging from 0 to 6). For each evidence level grouping, we calculated the mean implementation score for each quitline. We obtained reach and spending data from the 2009 North American Quitline Consortium Annual Survey of Quitlines.²⁰ We calculated treatment reach by dividing the number of tobacco users receiving counseling or medications from the quitline by the number of adult smokers in the state or province as estimated by the 2009 Behavioral Risk Factor Surveillance System or Canadian Tobacco Use Measurement Survey. We calculated spending by taking the total budget for quitline counseling services and medications and dividing it by the number of adult smokers in the state or province.
