Estimating early cervical rescreening is challenging due to incomplete data. This study suggests approximately 15.3% of Pap tests are early, with potential to reduce this by targeting service providers.

Area of Science:

  • Gynecologic Oncology
  • Public Health
  • Health Services Research

Background:

  • Determining the extent of early cervical rescreening is difficult due to incomplete patient testing histories, particularly with new screening registers.
  • Early cervical rescreening, or testing before the recommended interval, poses challenges for accurate measurement.

Purpose of the Study:

  • To estimate the rate of early cervical rescreening within the New South Wales Pap Test Register (PTR).
  • To identify systemic factors contributing to early rescreening and propose targets for intervention.

Main Methods:

  • Analysis of a one-month cohort of women with negative initial Pap test results from the New South Wales PTR (February 1997).
  • Exclusion of women with unrecorded positive test histories, with different approaches for high-grade (CIN2+) and low-grade (CIN1) results.

Related Experiment Videos

  • Estimation of early rescreening rates and potential reductions through service provider interventions.

    • Main Results:

    • Characteristic rescreening peaks observed at 6, 12, 18, 24, and 27 months post-initial negative test.
    • An estimated 15.3% of Pap tests represented early rescreening, affecting approximately 156,000 women in 1997-8.
    • A feasible target for reducing early rescreening is 7.4%, potentially freeing up nearly 200,000 screens for underscreened or unscreened women over two years.

    Conclusions:

    • Reasonable estimates of early cervical rescreening are achievable, though assumptions regarding positive test history are necessary, especially for new programs.
    • Systemic factors, likely driven by service providers, contribute significantly to early rescreening, indicated by characteristic peaks in rescreening patterns.
    • Interventions targeting service providers could reduce early rescreening rates, optimizing resource allocation for cervical cancer screening.
