Salvador-Bahia, 2018 Variable Pre-accreditation* (n = 186) Post-accreditation* (n = 186) p value Death General (%) 14 (7.5) 12 (6.4%) 0.684 a STEACS (%) 3 (1.6) 7 (3.8%) 0.738 b Non-STEACS (%) 11 (5.9) 5 (2.7%) 0.237 a Reinfarction General (%) 5 (2.7) 11 (5.9%) 0.125 a STEACS (%) 1 (0.5) 5 (2.7%) 0.399 b Non-STEACS (%) 4 (2.1) 6 (3.2%) 0.519 b Cardiogenic shock General (%) 8 (4.3) 6 (3.2%) 0.586 a STEACS (%) 2 (1.1) 4 (2.1%) 1 b Non-STEACS (%) 6 (3.2) 2 (1.1%) 0.298 b CRA (death or not) General (%) 14 (7.5) 15 (8.1%) 0.847 a STEACS (%) 3 (1.6) 9 (4.8%) 0.357 b Non-STEACS (%) 11 (5.9) 6 (3.2%) 0.382 a Combined unfavorable outcomes 20 (10.7) 24 (12.9%) 0.521 a (*) Absolute frequencies.

Leite et al. Accreditation in outcomes of patients with ACS Int J Cardiovasc Sci. 2019;32(6):607-614 Original Article each patient. The plan guides the therapeutic project of each area (nursing, physiotherapy, clinical practice, psychology, etc.), whose goals are always based on the pursuit of improvements of clinical results based on humanized practice. From the ONA 3 accreditation process, all prescriptions for the patients of the ACS line of care were then analyzed by the clinical pharmacist, who interacts directlywith themedical team, by signaling nonconformities, risks and suggestions.  In this study, regarding thedemographic characteristics of the sample, a higher mean age was found, with a difference of about 10 years, compared with the studies of Eagle et al. 15 and Chen et al. 23 which analyzed the impact of the evaluation of hospital services based on the standardization of these services. Moreover, this study has found a lower incidence of ACS in women and a higher prevalence of SAH compared to the results of the two studies mentioned above. 15,22 There was also a higher prevalence of diabetes mellitus and previous angioplasty; approximately the same prevalence of previous acute myocardial infarction; and a lower prevalence of patients with heart failure compared to patients from the study of Chen et al. 22 It can be assumed that, because the population sample of Salvador has more comorbidities than the population analyzed by Eagle et al. 15 and Chen et al. al. 22 , the patients in the sample may be associated with earlier infarction, since a considerable difference was observed between the mean ages of the patients in this study and those of the other authors cited. The hospitalization times at the Coronary Care Unit and at the hospital were analyzed and a tendency of reducedmedians has been found. As for the total sample and that of patients with non-ST-segment elevation ACS, there was a significant reduction in the length of
