21. A system comprising:
one or more medical devices configured to, for each of a plurality of collection periods and for each of a plurality of patient metrics, determine a respective value of the patient metric based on at least one of a sensed physiological condition of a patient or a therapy delivered to the patient, wherein the plurality of patient metrics comprises a fluid level metric, an atrial fibrillation metric, a ventricular heart rate during atrial fibrillation metric, and a night heart rate metric; and
processing circuitry configured to:
determine whether the patient is within a predetermined post-hospitalization period extending from a heart failure hospitalization period;
compare the determined values of each of the plurality of patient metrics to a first one or more criteria based on a determination that the patient is within the post-hospitalization period; and
compare the determined values of each of the plurality of patient metrics to a second one or more criteria, different from the first one or more criteria, based on a determination that the patient is not within the post-hospitalization period; and
determine a value indicating a likelihood that the patient will experience heart failure hospitalization based on the comparison of the values to the first one or more criteria or the second one or more criteria.
