Wong TH, et al. - Researchers performed a retrospective cohort study using national administrative, billing, and death records of Singapore residents discharged alive from Singapore public hospitals from January 2012 to December 2015, with a primary discharge diagnosis of cancer to identify factors associated with patients becoming Emergency Department (ED) frequent attenders (FA) after a cancer-related hospitalization. They observed that primary malignancies related to FA included brain and spine, head and neck cancers, lung, upper gastrointestinal, hepato-pancreato-biliary, and certain hematological malignancies. In addition, brain, lung, liver, and bone metastases were correlated with FA. It was concluded that there were cancer-specific factors contributing to ED frequent attendance. The study findings suggested that additional resources should be allocated to support high-risk groups and prevent unnecessary ED use.
