A medical care support device (11) includes an operation history acquisition unit (63), a prediction execution unit (64), and a display screen generation unit (62). The operation history acquisition unit (63) acquires an operation history in a case where a terminal device is operated. The prediction execution unit (64) predicts a next operation candidate in a case where the terminal device is input and operated by using a trained model generated by an external server learning the acquired operation history, the external server being installed outside the medical facility. The display screen generation unit (62) makes a proposal to the terminal device from the next operation candidate predicted by the prediction execution unit (64).
