An exemplary method involves operating an infusion device to deliver fluid to a user in accordance with a first operating mode of a plurality of operating modes, obtaining operational information pertaining to the first operating mode, and obtaining clinical information pertaining to the user. A destination operating mode of the plurality of operating modes is determined based at least in part on the operational information and the clinical information, and the infusion device is operated to deliver the fluid in accordance with the destination operating mode in a manner that is influenced by at least a portion of the operational information pertaining to the first operating mode. ## Claims ### Claim at position 1 1-20. (canceled) ### Claim 21 A processor-implemented method comprising: obtaining operational information of a fluid delivery device operating in accordance with a first automated operating mode of a plurality of automated operating modes, the operational information including a timer value of the first operating mode, the timer value corresponding to one of a group including a suspension timer and a refractory timer; obtaining clinical information pertaining to a user of the fluid delivery device; identifying, from the plurality of automated operating modes and based on the operational information and the clinical information, a second automated operating mode that is different than the first automated operating mode; and causing operation of the fluid delivery device to transition from the first automated operating mode to the second automated operating mode based on setting a timer value of the second automated operating mode equal to the timer value of the first automated operating mode, the timer value of the second automated operating mode corresponding to one of a group including a suspension timer and a refractory timer. ### Claim 22 (depends on 21) The method of claim 21, wherein the operational information comprises an exit reason for the first automated operating mode, and wherein the exit reason is used to determine whether to cause suspension or resumption of fluid delivery. ### Claim 23 (depends on 21) The method of claim 21, wherein identifying the second automated operating mode comprises excluding, based on the clinical information, an automated operating mode of the plurality of automated operating modes that will violate a rule. ### Claim 24 (depends on 23) The method of claim 23, wherein the clinical information comprises an amount of fluid delivered that indicates the automated operating mode will violate a fluid delivery limit. ### Claim 25 (depends on 23) The method of claim 23, wherein the clinical information comprises a glucose measurement value that indicates the automated operating mode will generate a user notification. ### Claim 26 (depends on 23) The method of claim 23, wherein the clinical information indicates the automated operating mode will automatically terminate. ### Claim 27 (depends on 21) The method of claim 21, wherein identifying the second automated operating mode comprises identifying a highest-ranked automated operating mode of the plurality of automated operating modes. ### Claim 28 A system comprising: one or more processors; and one or more processor-readable storage media storing instructions which, when executed by the one or more processors, cause performance of: obtaining operational information of a fluid delivery device operating in accordance with a first automated operating mode of a plurality of automated operating modes, the operational information including a timer value of the first operating mode, the timer value corresponding to one of a group including a suspension timer and a refractory timer; obtaining clinical information pertaining to a user of the fluid delivery device; identifying, from the plurality of automated operating modes and based on the operational information and the clinical information, a second automated operating mode that is different than the first automated operating mode; and causing operation of the fluid delivery device to transition from the first automated operating mode to the second automated operating mode based on setting a timer value of the second automated operating mode equal to the timer value of the first automated operating mode, the timer value of the second automated operating mode corresponding to one of a group including a suspension timer and a refractory timer. ### Claim 29 (depends on 28) The system of claim 28, wherein the operational information comprises an exit reason for the first automated operating mode, and wherein the exit reason is used to determine whether to cause suspension or resumption of fluid delivery. ### Claim 30 (depends on 28) The system of claim 28, wherein identifying the second automated operating mode comprises excluding, based on the clinical information, an automated operating mode of the plurality of automated operating modes that will violate a rule. ### Claim 31 (depends on 30) The system of claim 30, wherein the clinical information comprises an amount of fluid delivered that indicates the automated operating mode will violate a fluid delivery limit. ### Claim 32 (depends on 30) The system of claim 30, wherein the clinical information comprises a glucose measurement value that indicates the automated operating mode will generate a user notification. ### Claim 33 (depends on 30) The system of claim 30, wherein the clinical information indicates the automated operating mode will automatically terminate. ### Claim 34 (depends on 30) The system of claim 30, wherein identifying the second automated operating mode comprises identifying a highest-ranked automated operating mode of the plurality of automated operating modes. ### Claim 35 One or more non-transitory processor-readable storage media storing instructions which, when executed by one or more processors, cause performance of: obtaining operational information of a fluid delivery device operating in accordance with a first automated operating mode of a plurality of automated operating modes, the operational information including a timer value of the first operating mode, the timer value corresponding to one of a group including a suspension timer and a refractory timer; obtaining clinical information pertaining to a user of the fluid delivery device; identifying, from the plurality of automated operating modes and based on the operational information and the clinical information, a second automated operating mode that is different than the first automated operating mode; and causing operation of the fluid delivery device to transition from the first automated operating mode to the second automated operating mode based on setting a timer value of the second automated operating mode equal to the timer value of the first automated operating mode, the timer value of the second automated operating mode corresponding to one of a group including a suspension timer and a refractory timer. ### Claim 36 (depends on 35) The one or more non-transitory processor-readable storage media of claim 35, wherein the operational information comprises an exit reason for the first automated operating mode, and wherein the exit reason is used to determine whether to cause suspension or resumption of fluid delivery. ### Claim 37 (depends on 35) The one or more non-transitory processor-readable storage media of claim 35, wherein identifying the second automated operating mode comprises excluding, based on the clinical information, an automated operating mode of the plurality of automated operating modes that will violate a rule. ### Claim 38 (depends on 37) The one or more non-transitory processor-readable storage media of claim 37, wherein the clinical information comprises an amount of fluid delivered that indicates the automated operating mode will violate a fluid delivery limit. ### Claim 39 (depends on 37) The one or more non-transitory processor-readable storage media of claim 37, wherein the clinical information comprises a glucose measurement value that indicates the automated operating mode will generate a user notification. ### Claim 40 (depends on 37) The one or more non-transitory processor-readable storage media of claim 37, wherein the clinical information indicates the automated operating mode will automatically terminate.
