Sample item

A district health manager needs a quick, standardised population survey of people aged 50 years and above to estimate the prevalence and causes of blindness and the coverage of cataract surgery. Which method is designed for this purpose?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Rapid Assessment of Avoidable Blindness

RAAB is a rapid, population-based survey with cluster sampling of people aged 50 years and above. It estimates the prevalence and causes of blindness and visual impairment and the cataract surgical coverage so that services can be planned.

Option by option

  • A. Rapid Assessment of Avoidable Blindness (correct)

    Correct. RAAB is the standard rapid survey method.

  • B. Verbal autopsy

    Verbal autopsy is used to establish causes of death, not blindness.

  • C. Hospital-based record review

    A hospital record review reflects only those attending and not the community.

  • D. Sentinel surveillance at eye camps

    Sentinel surveillance at eye camps misses those who do not attend and is not population-based.
