To determine whether self-assessment of purified protein derivative of tuberculin (PPD) skin test reactions, done using a simple two-choice approach, is an effective screening method for tuberculosis.
Double-blind comparison between self-assessments and trained professional readings of PPD skin test reactions, done 72 hours after test administration.
The New York City Fire Department's Bureau of Health Services Participants : 2011 New York City firefighters and fire officers were given PPD skin tests during a mandatory retraining course.
Thirty-seven persons were excluded because of a history of a positive PPD skin test result or a bacille Calmette-Guérin vaccination.
All others agreed to participate in testing and self-assessment done using simple written instructions.
Self-assessment results were submitted just before trained professional readings were done.
Self-assessments and trained professional readings of PPD skin test reactions.
1833 participants (91%) interpreted their test reactions as flat.
Of these interpretations, 1824 (99.5%) matched the professional reading and 9 (0.5%) did not.
One hundred seventy-eight participants (9%) interpreted their test reactions as not flat ; 136 of these interpretations (76.4%) matched the professional reading and 42 (23.6%) did not (K=0.828 ; lower 95% confidence limit=0.790).
The predictive value of a negative self-assessment reading was 99. (...)
