Routine chest X-rays for tuberculosis screening in new students at the University of the West Indies are not effective. The study found no active tuberculosis cases, suggesting the screening program should be discontinued.

Area of Science:

  • Public Health
  • Medical Imaging
  • Infectious Disease Control

Background:

  • Mass radiographic screening for tuberculosis (TB) is declining globally.
  • The University of the West Indies (UWI) continues this practice for prospective students.
  • The cost-effectiveness and yield of this screening program at UWI are not well-established.

Purpose of the Study:

  • To evaluate the yield and cost of mass radiographic screening for tuberculosis among prospective students at UWI.
  • To determine if continued screening is warranted in this specific setting.

Main Methods:

  • A cross-sectional retrospective study design was employed.
  • Analysis of 12,662 chest X-ray reports from 1989 to 1997.
  • Assessment of tuberculosis detection rates and reported abnormalities.

Main Results:

  • No active cases of tuberculosis were detected among the screened students.
  • Three students reported a prior history of TB; 10 had a family history.
  • 399 clinically insignificant abnormalities were identified (e.g., mild scoliosis, calcified foci).

Conclusions:

  • Routine chest X-ray screening for tuberculosis at UWI yields minimal benefits.
  • The program exposes students to unnecessary radiation risks.
  • Discontinuation of this screening practice is recommended.
