The national coverage of cervical cancer screening in the US is falling, with about 1 in 4 women not up to date with screening1. Under-screened women bear the greatest burden of disease. Evidence shows 60-64% of American women diagnosed with cervical cancer were unscreened, highlighting the need to explore alternative methods to improve access2-4.
In the US, as with elsewhere, self-sampling for HPV primary cervical screening has the potential to increase access to screening in under screened groups. Evidence supports self-sampling as an acceptable, safe and reliable modality for specimen collection5. Self-collection of first-void urine (the first part of the urine stream, collected at any time of the day) has some advantages for HPV primary based screening, since it is non-invasive and easy to collect using a urine collection device. First-void urine contains higher concentrations of HPV DNA than subsequent void fractions and is therefore optimal for HPV screening6.
Healthcare professionals (HCPs) and providers who want to evaluate and promote the use of self-sampling for screening in their patient population can face barriers to introducing self-collection. To address this, we developed an implementation tool (a series of questions within key themes) to enable HCPs and providers to become active stakeholders in improving access to HPV primary screening by identifying opportunities for first-void-urine self-sampling. The tool was refined and validated with three US-based subject matter experts from different professions related to cervical cancer and HPV screening.
Whilst piloting the tool, the subject matter experts stated socioeconomic status and lack of insurance as two key characteristics associated with reduced screening. Other barriers include cultural differences, lack of education on available services and the importance of screening and medical distrust. Understanding the benefits of first-void was identified as a barrier among HCPs. Many HCPs are not aware of urine-based self-sampling and will not have the same understanding of the definition of “first-void”.
The tool provides a starting point to enable US HCPs working in women’s health to be active stakeholders in shaping how HPV primary cervical cancer screening programs are designed and implemented to optimise access, early detection and prevention. This framework can be further adapted for use by other stakeholders, geographies, and healthcare systems. More education is needed on the benefits of self-sampling to address unmet need in cervical cancer screening and a clear definition of “first-void-urine” will reduce confusion.
