1. A method of operating a medical device system for assessing decongestive therapy delivered to a heart failure patient, comprising:

  • sensing a physiologic parameter indicative of the patient'"'"'s diuresis status via a sensing circuit of the medical device system;

    delivering the sensed physiologic parameter to a processing module of the medical device system;

    determining, by the processing module, when a target level of patient diuresis has been achieved based on either;

    (1) a change of the sensed physiologic parameter that matches a specified value of the physiologic parameter for a previous prior success of achieving the target level of patient diuresis;

    or(2) a rate of change of a difference between the sensed physiologic parameter and a target parameter threshold meeting a target rate of change; and

    producing an output in response to determining that the target level of patient diuresis has been achieved according to the processing module determination, wherein the output comprises one or more of adjusting system-regulated decongestive therapy and presenting a patient response to therapy notification via a user interface of the medical device system.
