To investigate whether primary care patients who claim to smoke tobacco gain greater benefit of a patient information leaflet (PIL) on oral cancer than nonsmokers.
Two studies were conducted. Study 1 examined the research question initially, and Study 2 acted as a replication and inclusion of additional secondary outcome measures. The leaflet was designed and tested in an earlier study. Knowledge of oral cancer was assessed by a previously validated 36-dichotomous-item scale. A single-item question ascertained self-reported smoking status (kappa = 0.94). Study 1 participants were drawn from 14 practices (6 medical, 8 dental). A randomised control group design was adopted. The experimental group received the leaflet on attendance to the practice and then completed the questionnaire. The control group received the questionnaire only. Complete data were collected from 739 respondents. The design of Study 2 was identical; 786 new respondents from 16 practices (7 medical, 9 dental) were collected.
Both studies confirmed that smokers knew less about oral cancer than nonsmokers (P < 0.05) when access to the leaflet had been denied. On receipt of the leaflet, there was no distinction in oral cancer knowledge between the smoking status categories of respondents. Evidence of reassurance about screening from leaflet exposure was supported by the second study.
This programmed research has demonstrated an effect of a brief PIL to offset the decrement in oral cancer knowledge observed in primary care patients who use tobacco in comparison to their nonsmoking counterparts. The leaflet reduced anxiety about oral health screening in smokers.
调查声称吸烟的初级保健患者是否比不吸烟者从口腔癌患者信息手册（PIL）中获得更大益处。
进行了两项研究。研究1最初检验了该研究问题，研究2作为重复研究并纳入了额外的次要结局指标。该手册在早期研究中进行了设计和测试。通过先前验证的36项二分制量表评估口腔癌知识。一个单项问题确定自我报告的吸烟状况（kappa = 0.94）。研究1的参与者来自14个医疗机构（6个医疗，8个牙科）。采用随机对照组设计。实验组在就诊时收到手册，然后完成问卷。对照组仅收到问卷。从739名受访者收集了完整数据。研究2的设计相同；从16个医疗机构（7个医疗，9个牙科）收集了786名新受访者。
两项研究均证实，在未获得手册时，吸烟者对口腔癌的了解比不吸烟者少（P < 0.05）。收到手册后，受访者的吸烟状况类别在口腔癌知识方面没有差异。第二项研究支持了因接触手册而对筛查感到安心的证据。
这项程序化研究表明，一份简短的患者信息手册可抵消与不吸烟的初级保健患者相比，吸烟患者在口腔癌知识方面的减少。该手册减轻了吸烟者对口腔健康筛查的焦虑。
