Characterisations of adverse events detected in a university hospital: a 4-year study using the Global Trigger Tool method

Abstract: ObjectivesTo describe the level, preventability and categories of adverse events (AEs) identified by medical record review using the Global Trigger Tool (GTT). To estimate when the AE occurred in the course of the hospital stay and to compare voluntary AE reporting with medical record reviewing.DesignTwo-stage retrospective record review.Setting650-bed university hospital.Participants20 randomly selected medical records were reviewed every month from 2009 to 2012.Primary and secondary outcome measuresAE/1000 p… Show more

“…Concerning the rate of AEs, the results found in our study are higher than those found in other studies: Landrigan et al (2010), Rutberg et al (2014), Rozenfeld, Giordani, and Coelho (2013) Classen et al (2011), the rate of 25.1 AEs per 100 admissions found by Landrigan et al (2010), and the rate of 14.5 AEs per 100 admissions found by Hwang et al (2014). Although the rate of AEs found in this study (31.1%) is slightly lower than that found by Classen et al (2011), 33.3%, it is higher than the rates reported by Landrigan et al (2010), 18.1%, Hwang et al (2014), 7%, and Rutberg et al (2014), 20.5%.…”

The significant differences found between the results from the various studies could have been influenced by several factors, such as the organizational structure, the hospital's safety culture, the type of inpatients, the context where the study was carried out, the review process, and the reviewers' training.…”

“…A study using the Global Trigger Tool developed by the Institute for Healthcare Improvement provided a best estimate of 16% as the baseline rate for CD. 7 A total of 2000 hospitalizations were planned to be included to have a power of at least 80% to detect a 25% reduction in the annual incidence of CD with a 2-tailed type I error rate of 0.05. Comparisons of dichotomous event rates were made using chi square tests at a 2-tailed level for significance of 0.05.…”

“…Tanto os erros como os eventos adversos podem implicar em aumento do tempo de internação, custos assistenciais e muitas vezes, encargos jurídicos (4) . Ao entender a relação da ocorrência dos eventos adversos com os resultados assistenciais, a Aliança Mundial para a Segurança do Paciente foi criada, no intuito de estabelecer metas e protocolos mundiais de atendimento voltados à segurança (3) .…”
