Colorectal cancer screening rates are low among disadvantaged patients; few studies have explored barriers to screening in community health centers. The purpose of this study was to describe barriers to/facilitators of colorectal cancer screening among diverse patients served by community health centers.
We identified twenty-three outpatients who were eligible for colorectal cancer screening and their 10 primary care physicians. Using in-depth semi-structured interviews, we asked patients to describe factors influencing their screening decisions. For each unscreened patient, we asked his or her physician to describe barriers to screening. We conducted patient interviews in English (n = 8), Spanish (n = 2), Portuguese (n = 5), Portuguese Creole (n = 1), and Haitian Creole (n = 7). We audiotaped and transcribed the interviews, and then identified major themes in the interviews.
Four themes emerged: 1) Unscreened patients cited lack of trust in doctors as a barrier to screening whereas few physicians identified this barrier; 2) Unscreened patients identified lack of symptoms as the reason they had not been screened; 3) A doctor's recommendation, or lack thereof, significantly influenced patients' decisions to be screened; 4) Patients, but not their physicians, cited fatalistic views about cancer as a barrier. Conversely, physicians identified competing priorities, such as psychosocial stressors or comorbid medical illness, as barriers to screening. In this culturally diverse group of patients seen at community health centers, similar barriers to screening were reported by patients of different backgrounds, but physicians perceived other factors as more important.
Further study of these barriers is warranted.
弱势患者的结直肠癌筛查率较低;很少有研究探讨社区卫生中心筛查的障碍。本研究的目的是描述社区卫生中心服务的不同患者中结直肠癌筛查的障碍/促进因素。
我们确定了23名符合结直肠癌筛查条件的门诊患者及其10名初级保健医生。通过深入的半结构化访谈,我们要求患者描述影响其筛查决策的因素。对于每一位未接受筛查的患者,我们要求其医生描述筛查的障碍。我们用英语(n = 8)、西班牙语(n = 2)、葡萄牙语(n = 5)、葡萄牙克里奥尔语(n = 1)和海地克里奥尔语(n = 7)对患者进行访谈。我们对访谈进行录音和转录,然后确定访谈中的主要主题。
出现了四个主题:1)未接受筛查的患者认为对医生缺乏信任是筛查的障碍,而很少有医生认识到这一障碍;2)未接受筛查的患者认为没有症状是他们未接受筛查的原因;3)医生的建议或缺乏建议,对患者的筛查决策有显著影响;4)患者(而非其医生)将对癌症的宿命论观点视为障碍。相反,医生认为相互竞争的优先事项,如心理社会压力源或合并症,是筛查的障碍。在社区卫生中心就诊的这群文化背景多样的患者中,不同背景的患者报告了类似的筛查障碍,但医生认为其他因素更重要。
有必要对这些障碍进行进一步研究。
