Hello everyone!
I'm currently writing a systematic review and I just can't figure out the study design of one of the included studies. The study is from Davis et al. (2002) with the title "Swallowing with a tracheostomy tube in place: does cuff inflation matter?". The aim of the study was to assess the frequency of aspiration with an inflated versus a deflated cuff and to see if the texture swallowed made any difference.
The authors included 12 patients and evaluated swallowing of four viscosities (e.g. thin liquid, pureed food) with the cuff inflated and with the cuff deflated (so eight evaluations in total). The assessor who evaluated aspirations was blinded to cuff inflation status. The order of testing is not described in the text. They used logistic regression analysis and the McNemar test for analysis of the two groups with (p<0,05).
I think it should be a cohort study with the patients being their own controls. Is that possible?
In the study there's only written that's it's a prospective, blinded analysis.
I'm very thankful for any help!
