Objective::
To analyze whether an increase in patient severity and nursing workload are correlated to a greater incidence of adverse events (AEs) in critical patients.
Method::
A prospective single cohort study was performed on a sample of 138 patients hospitalized in an intensive care unit (ICU).
Results::
A total of 166 AEs, occurred, affecting 50.7% of the patients. Increased patient severity presented a direct relationship to the probability of AEs occurring. However, nursing workload did not present a statistically significant relationship with the occurrence of AEs.
Conclusion::
The results cast light on the importance of using evaluation tools by the nursing personnel in order to optimize their daily activities and focus on patient safety.
Objetivo::
Analisar se o aumento da gravidade do paciente e a carga de trabalho de enfermagem está relacionado à maior incidência de Eventos Adversos (EAs) em pacientes críticos.
MéTodo::
Estudo de coorte única, prospectivo, com amostra de 138 pacientes internados em uma Unidade de Terapia Intensiva (UTI).
Resultados::
Ao todo, foram evidenciados 166 EAs, que acometeram 50,7% dos pacientes. O aumento da gravidade do paciente apresentou relação direta com a chance de ocorrência de EAs. Entretanto, a carga de trabalho de enfermagem não apresentou relação estatisticamente significativa, na ocorrência de EAs.
ConclusãO::
Os resultados permitem refletir acerca da importância da equipe de enfermagem, em utilizar instrumentos de avaliação, com o objetivo de melhorar e planejar suas ações diárias, com foco na segurança do paciente.
