Adolygiad Sylfaenol NICE
Mae'r awduron yn datgan:
"This review contains assessments of the available evidence on the impact of quitlines on smoking cessation. A comprehensive literature search was conducted and a total of 984 titles and abstracts were screened, with 32 studies identified as direct evidence."
Mae'r awduron yn datgan:
"The quality of evidence on the impact of quitlines on smoking cessation is reasonably high, and a number of controlled studies exist exploring the effectiveness of telephone counselling on smoking cessation amongst the general population and specific population subgroups. Two 1+ American studies found that reactive quitlines improved abstinence rates over the distribution of self-help materials alone. Supplementary evidence from three 2+ studies also supports the effectiveness of reactive telephone quitlines, as all studies report 12-month abstinence rates of between 8.2% to 15.6%. There is also a consistent body of evidence from a 1++ Cochrane Review and two 1+ meta-analyses that proactive telephone counselling has a modest effect on smoking cessation – whether this counselling occurs in the context of a quitline or not."
