A Response to: Quality Improvement in Delirium Health Literacy in Older Adult Patients and Their Caregivers Attending a Geriatric Clinic [Response to Letter]

Dear editor

I have read with interest the paper by Azar et al, about the improvement in delirium health literacy they achieved in older adult patients and their caregivers, while attending a geriatric clinic.¹

The improvement in delirium literacy close to complete competence is valuable indeed, and it is worthily warranted, as its need is apparent.

Yet I am just concerned about the statistical tool Authors adopted in their analysis. I suggest to verify if their results still persist using a different test. As far as I know, in case of pre-post comparisons, instead of Chi-square test [which requires independence of observations], McNemar test should be employed, as it fits for contingency tables whose observations are serially linked.²

Anyway, I share Authors’ intentions: having worked longtime leading a geriatric rehabilitation ward, in a skilled multi-purpose teaching nursing home, I do agree on the educational role of such kind of units.
