To the Editor: We would like to comment on some important inaccuracies in Vickery and Thompson's article on general practitioner management of patients after an acute coronary syndrome.1
The authors state that unassisted cessation of smoking (quitting without professional support or pharmacotherapy) is the most effective method. In fact, it is the least successful method and produces quit rates of only 3%–5% at 6–12 months.2 In comparison, the quit rate from combined counselling and pharmacotherapy ranges from 22% to 32%, depending on the intensity of counselling provided.3
Although many smokers ultimately quit without help, it is usually after numerous failed attempts. Each year that smokers delay quitting after the age of 35 results in a 3-month reduction in life expectancy.4 It is therefore vital that smokers stop at the earliest possible opportunity and that every quit attempt has the best possible chance of success.
We advise doctors to follow the Australian5 and United States.3 smoking cessation guidelines, which recommend the use of pharmacotherapy and counselling for all nicotine-dependent smokers.
The authors have also misinterpreted the Cochrane review data for the efficacy of nicotine replacement therapy (NRT). They state that 50%–70% of people achieve abstinence with NRT. However, the absolute long-term quit rate is only 6%–12% more than for placebo.6 The confusion may have arisen because NRT increases the rate of quitting by about 50%–70% compared with placebo.
