This is a large pragmatic, randomized controlled trial to test the real-world effectiveness of inpatient palliative care consultative services in improving a number of patient- and family-centered processes and outcomes of care among seriously ill hospitalized patients. The investigators hypothesize that improved patient-centered outcomes can be achieved without higher costs by simply changing the default option for inpatient palliative care consultation for eligible patients from an opt-in to an opt-out system. To test this hypothesis the investigators will conduct a clinical trial at 11 hospitals using the same electronic health record within Ascension Health, the largest non-profit health system in the U.S.
