The use of handheld colposcopy in nurse-led cervical cancer screening programs could enhance screening quality and diagnostic accuracy, especially in high-burden regions like sub-Saharan Africa. This study assessed the feasibility of using the Pocket colposcope (Calla Health Foundation, Durham, NC) among healthcare providers in western Kenya. Feasibility was defined in terms of acceptability and image quality. A mixed-methods approach was employed, involving healthcare providers from three clinics offering cervical cancer screening. These providers used the Pocket colposcope more than once within 2 months of the survey. Semi-structured interviews were conducted to explore provider experiences and the device's acceptability, which was measured using Likert scale questions based on Sekhon's Theoretical Framework of Acceptability (TFA). This framework evaluates affective attitude, burden, ethicality, perceived effectiveness, intervention coherence, self-efficacy and opportunity cost. Additionally, expert gynecologists assessed the quality of cervical images from visual inspection with acetic acid and/or human papillomavirus-positive patients ( = 123), rating them on a scale of 1 to 3. Interobserver agreement was assessed using Cohen's kappa. Quantitative and qualitative data were analysed using STATA 18.0 and Dedoose 9.0.17, respectively. Among the eight providers interviewed, including five nurses, the average experience in cervical cancer screening was 4.2 years. The Pocket colposcope received a mean acceptability score of 4.18 (SD = 0.27) out of five based on the seven TFA constructs. Qualitative findings highlighted positive aspects, such as better cervix visualisation, improved post-treatment monitoring, easier external consultations and enhanced patient education. However, challenges incl‑uded camera and software issues and limited personnel for documentation. Image quality was rated 2.23 out of 3, with fair interobserver agreement (Cohen's kappa 0.36, < 0.001). The study concluded that the Pocket colposcope is acceptable in nurse-led cervical cancer screening programs but emphasised the need for improvements in image quality and technology reliability. Expanding training could further enhance its utilisation.
在护士主导的宫颈癌筛查项目中使用手持式阴道镜可以提高筛查质量和诊断准确性,尤其是在撒哈拉以南非洲等高负担地区。本研究评估了在肯尼亚西部的医疗服务提供者中使用口袋式阴道镜(Calla Health Foundation,北卡罗来纳州达勒姆)的可行性。可行性根据可接受性和图像质量来定义。采用了混合方法,涉及来自三家提供宫颈癌筛查诊所的医疗服务提供者。这些提供者在调查后的2个月内多次使用口袋式阴道镜。进行了半结构化访谈,以探索提供者的体验和该设备的可接受性,使用基于塞洪可接受性理论框架(TFA)的李克特量表问题进行测量。该框架评估情感态度、负担、伦理、感知有效性、干预一致性、自我效能和机会成本。此外,专家妇科医生对醋酸视觉检查和/或人乳头瘤病毒阳性患者(=123)的宫颈图像质量进行评分,评分范围为1至3。使用科恩kappa评估观察者间一致性。分别使用STATA 18.0和Dedoose 9.0.17分析定量和定性数据。在接受访谈的八名提供者中,包括五名护士,宫颈癌筛查的平均经验为4.2年。基于七个TFA结构,口袋式阴道镜的平均可接受性得分为4.18(标准差=0.27)(满分5分)。定性研究结果突出了积极方面,如宫颈可视化更好、治疗后监测改善、外部咨询更容易以及患者教育增强。然而,挑战包括相机和软件问题以及记录人员有限。图像质量评分为2.23(满分3分),观察者间一致性一般(科恩kappa为0.36,<0.001)。该研究得出结论,口袋式阴道镜在护士主导的宫颈癌筛查项目中是可接受的,但强调需要提高图像质量和技术可靠性。扩大培训可以进一步提高其利用率。
