Alterations to calling criteria for Between the Flags (an early warning system)

Abstract

Early warning systems aim to detect clinical deterioration of patients at an early stage. Between the Flags was introduced in New South Wales Health for this purpose. When patients are transferred from the emergency department to the ward, there are circumstances when the calling criteria need to be altered to take into account the clinical context. It is recognised that confusion exists among junior medical staff about the process of making alterations to the Between the Flags calling criteria.A quality improvement project was implemented by undertaking a baseline survey of junior medical staff, providing education and training (to junior medical staff on the existing guidelines for making alteration to the calling criteria), and conducting a post-implementation survey.A baseline survey demonstrated that 74% of junior medical staff had received no education on making alterations and only 5% knew how long their alterations would last once the patient was transferred to the ward. This has potentially serious consequences for patient safety following transfer.After implementation of training, we found that 63% of junior medical staff were aware of the guidelines on making alterations and 50% knew how long their alterations would last once the patient was transferred to the ward. We conclude that educating junior medical staff improved knowledge on the guidelines for making alterations to calling criteria.
