Similar findings also were observed in a case-control
study of adults aged 65 years or older at a rural community
hospital in Ohio (USA) during 2004 and 2006. The authors
of this study explored the risk for pneumonia as cause of
hospitalization with the use of atypical antipsychotics and
other non-neuropsychiatric drug classes that were suspected
to be possible risk factors for CAP [11]. As compared to
patients unexposed to study drugs, users of atypical
antipsychotics were associated with a significant increase
in the risk for CAP
