Four post-hoc analyses of prior trials found smokers using nicotine patch following a lapse were less likely to progress to relapse compared to those using a placebo patch following a lapse. We attempted a conceptual replication test of these results via a randomized trial of instructions to continue vs. stop nicotine patch after a lapse.
Smokers trying to quit (n=701) received nicotine patch (21/14/7mg) and brief phone counseling (six 15-min sessions). We randomized smokers to receive instructions for and rationale for stopping vs. continuing patch after a lapse. The messages were repeated before and after cessation and following lapses via counseling, phone and written instructions.
Among those who lapsed, those told to Continue Patch did not have a greater incidence of 7-day abstinence at 4months (primary outcome) than those told to Discontinue Patch (51% vs. 46%). Most (81%) participants in the Discontinue condition stopped patch for only 1-2days and then resumed abstinence and patch use. Analyses based on all participants randomized were similar. Adverse events were as expected and did not differ between conditions.
Instructions to continue nicotine patch after a lapse did not increase return to abstinence. These negative results may have occurred because actual use of patch after a lapse was similar in the two conditions. Also, allowing patch use while smoking may have reduced motivation to stay abstinent.
四项先前试验的事后分析发现,与使用安慰剂贴片相比,在出现戒断后使用尼古丁贴片的吸烟者再次复吸的可能性较小。我们通过一项随机试验,对这些结果进行了概念复制测试,即在出现戒断后,参与者被随机分配继续或停止使用尼古丁贴片。
试图戒烟的吸烟者(n=701)接受尼古丁贴片(21/14/7mg)和简短的电话咨询(六次 15 分钟的疗程)。我们随机分配吸烟者接受停止或继续使用贴片的指示和理由。在戒烟前、戒烟后和出现戒断后,通过咨询、电话和书面指示重复这些信息。
在出现戒断的人群中,那些被指示继续使用贴片的人在 4 个月时(主要结果)的 7 天戒烟率并没有比那些被指示停止使用贴片的人更高(51%比 46%)。在停止贴片的参与者中,大多数(81%)只停止了 1-2 天,然后恢复了戒烟和贴片的使用。基于所有随机分组的参与者的分析结果相似。不良事件与预期相符,且在两种情况下没有差异。
在出现戒断后指示继续使用尼古丁贴片并没有增加恢复戒烟的比例。这些负面结果可能是因为在两种情况下,实际使用贴片在出现戒断后都很相似。此外,允许在吸烟时使用贴片可能会降低保持戒烟的动机。
