Description
SINUSITYR identifies sample adults and, beginning in 2007, sample children whom a doctor or other health professional had diagnosed with sinusitis during the past 12 months.
The Field Representative's Manual for 2001 forward defines sinusitis as "an inflammation of a sinus." In the 2007 Manual the following definition was also provided: "Sinusitis is an inflammation of the sinuses usually caused by viral, bacterial, or fungal infection. This can interfere with normal sinus drainage and cause increased mucus production." These definitions were not routinely shared with respondents.
