In the article entitled “Stroke Unit Care in a Real-Life Setting: Can Results From Randomized Controlled Trials Be Translated Into Every-Day Clinical Practice? An Observational Study of Hospital Data in a Large Australian Population” by Gattellari et al,1 several references are incorrect. On page 16, paragraph 3, the sentences “Generally, comorbidities are under-numerated in administrative data-sets,23 although these are accurate when recorded.”12,18 and “Coding standards specify noting all conditions affecting care during a patient’s hospital stay.”12 should be replaced with “Generally, comorbidities are under-numerated in administrative data-sets, although these are accurate when recorded.”23,24 and “Coding standards specify noting all conditions affecting care during a patient’s hospital stay.”9 The authors have added a reference 24 (cited as Powell H, Lim LL, Heller RF. Accuracy of administrative data to assess comorbidity in patients with heart disease: an Australian perspective. J Clin Epidemiol. 2001; 54:687–693). Furthermore, the authors would like to note that although references 18 and 20, and 19 and 21 are identical, these references are appropriately cited in the text. The authors regret these errors.
