Prostate-specific antigen (PSA) screening is common in elderly men over 75, despite recommendations against it. More education is needed on PSA screening risks and benefits for this age group.

Area of Science:

  • Urology
  • Geriatric Medicine
  • Public Health

Background:

  • Prostate-specific antigen (PSA) screening for prostate cancer remains controversial due to unestablished efficacy.
  • General consensus advises against PSA screening for men aged 75 and older.
  • Despite guidelines, PSA screening is prevalent in the elderly population.

Purpose of the Study:

  • To determine the rate of PSA screening among men aged 75 years or older.
  • To compare PSA screening rates in elderly men with other cancer screening methods.
  • To assess the extent of risk-benefit discussions before PSA screening in elderly men.

Main Methods:

  • Analysis of a nationally representative sample of 7889 men from the 2000 National Health Interview Survey.
  • Calculation of screening rates and confidence intervals for PSA, fecal occult blood, and Pap smear screenings.

Related Experiment Videos

  • Survey questions on physician recommendation and discussion of risks/benefits prior to screening.

    • Main Results:

    • PSA screening was utilized by 32.5% of men aged 75 or older.
    • PSA screening rates in this demographic exceeded fecal occult blood screening (22.8%) and were similar to Pap smear screening in women (29.0%).
    • Physician recommendation initiated screening in 88.4% of cases, with risk/benefit discussions reported by 66.5%.

    Conclusions:

    • A significant proportion of elderly men (≥75 years) undergo PSA screening, contrary to established recommendations.
    • Physician recommendation is a primary driver for PSA screening in this age group.
    • Enhanced strategies are required to improve understanding of PSA screening's risks and benefits among elderly men.
