Community health agents can effectively instruct women in rural areas on self-collected cervical sampling for high-risk HPV (hrHPV) detection, improving cervical cancer screening access.

Area of Science:

  • Gynecology
  • Public Health
  • Infectious Disease

Background:

  • Cervical cancer screening is crucial for early detection and prevention.
  • Access to screening remains a challenge in poor rural settings.
  • Community Health Agents (CHAs) can play a vital role in healthcare delivery.

Purpose of the Study:

  • To assess the efficacy of CHAs in teaching self-collected cervical sampling.
  • To compare high-risk Human Papillomavirus (hrHPV) detection rates between self-collected and gynecologist-collected samples.

Main Methods:

  • CHAs received one-day training on instructing women in self-sampling techniques.
  • Women provided self-collected samples using a brush and collection medium.
  • Gynecologists collected samples from the same women one week later for comparison.

Main Results:

  • Self-collected samples showed a higher prevalence of hrHPV (33.9%) compared to gynecologist-collected samples (28.6%).
  • Significant discordance was observed between self-collected and provider-collected hrHPV results (P<0.01).
  • Both sampling methods missed one case of histologically confirmed high-grade squamous intraepithelial lesion.

Conclusions:

  • Self-collected vaginal sampling is a viable additional function for CHAs.
  • Integrating this method can enhance cervical cancer screening accessibility in underserved rural populations.
  • This approach holds potential for improving public health outcomes in resource-limited settings.
