Causes and factors associated with unplanned hospital readmissions in adult cancer patients: a retrospective cohort study in Singapore

Background:Hospital readmissions are costly, increasingly common and potentially preventable events. This numbers will continue to rise in the advent of ageing population with anticipation of increasing demand for healthcare resources. A more in-depth analysis of literatures revealed that some of these unplanned hospital readmissions were potentially avoidable and limited information were available to address the causes and factors associated with unplanned hospital readmission in adult cancer patients. Objective:i) To establish the causes and risk factors associated with unplanned hospital readmissions (potentially avoidable and unavoidable) for adult cancer patients. ii) To explore the modifiable risk factors for potentially avoidable unplanned readmissions for adult cancer patients. Methods:A cohort study involving an audit of retrospective data from medical records to identify factors associated with unplanned hospital readmission for adult cancer patients. Logistic regression will be utilized for data analysis. Results:Risk factors associated with unplanned hospital readmission for cancer patients will be reported and presented at the conference. Discussion:Risk factors identified will be utilized to develop a risk model to stratify the group of cancer patients who are at risk of unplanned readmissions and frequent emergency department visits. Conclusion:With this model, cancer patients who are at risk are identified early and targeted interventions would be initiated address modifiable factors. The outcome measures would include improved utilization of hospital beds, emergency department services and enhanced quality of care.
