1. A method of controlling operation of a medical device that regulates delivery of a fluid medication to a user, the method comprising:
obtaining a current sensor-generated value that is indicative of a physiological characteristic of the user, the current sensor-generated value produced in response to operation of a continuous analyte sensor device;
calculating a sensor quality metric that indicates accuracy of the current sensor-generated value, wherein the sensor quality metric is calculated from information generated by or derived from the continuous analyte sensor device;
adjusting, in response to the calculated sensor quality metric, therapy actions of the medical device to configure a quality-specific operating mode of the medical device, wherein adjusting the therapy actions comprises separately regulating basal and bolus deliveries based on the calculated sensor quality metric;
managing generation of user alerts at the medical device in response to the calculated sensor quality metric; and
regulating delivery of the fluid medication from the medical device, in accordance with the current sensor-generated value and the quality-specific operating mode of the medical device.
