Breath Counter: a new device for household diagnosis of childhood pneumonia.

ABSTRACT

Illiterate Traditional Birth Attendants (TBAs) were trained to diagnose pneumonia in children using their visual judgement of tachypnoea. This method resulted in 41% wrong diagnosis in the cases with borderline respiratory rate. A simple device, named 'Breath Counter' was designed and TBAs were trained to diagnose pneumonia in children using this instrument. The agreement of TBAs' diagnosis, with diagnosis using WHO criteria of respiratory rate improved from unaided 60% (30/50) to 82% (41/50) by the use of Breath Counter (p less than 0.05). Breath Counter is simple, cheap, effective and can be used even by illiterate persons to diagnose pneumonia in children. It has the potential of becoming a household diagnostic aid.
