“…Some of them are the surveys of medical device accidents and user errors (Carol, 2003;Hijazi, 2011;Brennan, 1991;Sawyer, 1997;Sezdi, 2009a). Some of them are focused on only electrical safety (Barbosa et al, 2010;Osman et al, 1996;Chakrabartty et al, 2010;Bakes, 2007;Sezdi, 2009b), whereas the others examined both the sterilization and reusage of single use devices related to the patient safety (Yoleri, 2011;Rice et al, 2009;Quirk, 2002;Northrup, 2000;Day, 2004;Koh, 2005;Buchdid Amarante, 2008;Hailey et al, 2008). There are also studies that explain the classification of clean rooms by measuring particles (Sezdi, 2009c).…”
