A patient-support apparatus according the present disclosure has a head end and a foot end. The patient-support apparatus includes a source of pressurized air, a plurality of bladders, a manifold, a plurality of pressure sensors, and a controller. The controller includes a processor, a timer, and a memory device. The processor configured to execute instructions from the memory so that the processor retrieves a baseline patient-specific profile from the memory, calculates a first patient outcome corresponding to an amount of migration of a patient toward the foot end of the bed over time, updates the baseline patient-specific profile to include the first patient outcome, calculates a set of operating parameters based on the updated patient-specific profile, the set of operating parameters including a set of target pressures for the plurality of bladders, and adjusts the pressures in the bladders to the target pressures.
