After hospitalization,the patient faces a brief fragile period of susceptibility to disease and a high incidence of adverse events(re-admission or death,etc.),which is described by cardiologist Harlan M.Krumholz as post-hospital syndrome(PHS).PHS is characterized by the risk of early re-hospitalization towing to physiologic stressors from the initial admission,including disruption in sleep-wake cycles,inadequate pain control,deconditioning,and changes in nutritional status.Almost 1 in 6 patients hospitalized for acute myocardial infarction and 1 in 5 of those admitted for heart failure are readmitted within 30 days of discharge.Notably,only 10% and 35% are readmitted for the same diagnosis as that of the original hospitalization,respectively.Through a systematic review,this paper discusses the related concepts,hazards and influencing factors of PHS,and summarizes the counter measures based on the domestic status,in order to provide reference for domestic clinical medical personnel to formulate relevant measures to reduce the incidence of PHS.
