A system comprising: an input/output device; and one or more processors configured to: receive a current data transmission from a remote device; acquire patient metrics from the current received data transmission; determine a daily heart failure risk status for each day occurring during a time period from a previous received data transmission to the current received data transmission based on the acquired patient metrics, wherein determining each heart failure risk status comprises selecting one of a plurality of heart failure statuses; determine a maximum daily heart failure risk status of the determined daily heart failure risk statuses during a lookback window prior to receipt of the current received data transmission; determine a transmission heart failure risk status for the current received data transmission based on the determined maximum daily heart failure risk status; and determine a heart failure risk status differentiation for the current received data transmission based on a temporal proximity of the determined maximum daily heart failure risk status and receipt of the current received data transmission; and wherein the one or more processors are further configured to: determine that the transmission heart failure risk status is ongoing in response to at least determining that a transmission heart failure risk status of a previous data transmission received within the lookback window is the same as the transmission heart failure risk status of the current received data transmission and a most recent daily heart failure risk status in a previous data transmission that is the same as the transmission heart failure risk status of the current received data transmission is within the lookback window; and determine that the transmission heart failure risk status is new in response to determining that no transmission heart failure risk status of any previous data transmission received within the lookback window is the same as the transmission heart failure risk status of the current received data transmission or that the most recent daily heart failure risk status in a previous data transmission that is the same as the transmission heart failure risk status of the current received data transmission is not within the lookback window. an input/output device;
