Project main description

Rapid identification of hospitalized patients at high risk of extended length of stay, readmission or death has the potential to improve quality of care and reduce avoidable harm and costs. Early and accurate identification of patients at high risk of death can be used to call emergency medical teams to prevent death or alternatively to initiate counseling about end-of-life care. An accurate estimate of length of stay together with risk of readmission and death can help clinicians with important discharge planning strategies for their patients; these strategies are likely to improve continuity of care, and prevent readmissions and post-discharge deaths.

We are developing non disease-specific predictive models that simultaneously estimate the future daily probability of being in hospital, at home or dead for a hospitalised patient over a period of time following a temporal event (e.g. new pathology test result). This provides a more comprehensive, finer-grained forecast of patient status. In addition, these predictions are continuously updated as new information becomes available. These properties make these models suitable to aid in decision making at the point-of-care.
