The purpose of the study was to explore the relationship between the capability of the managing the activity of daily living (ADL) of elderly patients and the decision of the disposition of these patients to a sanatorium following discharge from the hospital. A case-controlled study was used and 50 patients who were planning for discharge were selected. A structured survey was used and the data collected were also from the patients’ medical records, interviews and observation. The results show that the issues, which impact the decision for the disposition after hospital discharge were: the length of stay in the hospital, stayed in sanatorium prior to their admission, the accompaniment of surgical items such as drainage tubes and the level of dependence on the ADLs of the patients. The most significant findings were that patients who stayed in sanatorium prior to their admission and those with long periods of hospitalization were likely to be discharged to a sanatorium. The results provide information for the medical department in taking into consideration the need to develop a long-term care resource center. Moreover, it is also necessary to educate and train caregivers of patients who have been hospitalized for a long time.
