Not only is your husband passing though dasha and bhukthi of 12th lord which is for hospitalization. He is also in the period of Shani sade satti. Ketu presently in the 3rd house till March 2019 and thereafter in the 2nd house of finance after Match 2019 is not good. Possibility of a job change is likely during this period.
He should do remedies of Saturn every Saturdays for benefits.
