The number of adults over 65 years of age with diabetes mellitus (DM) is increasing worldwide and is estimated to reach 26.7 million by 2050 [1]. Accordingly, hospital admissions for adults over 65 years with DM are also increasing. Admissions are three times more common among adults older than 65 years than those younger than 45 years [2]. Additionally, hospitalized individuals with DM tend to have more comorbidities than those without DM, which is associated with poor prognosis [3]. Some patients with DM may experience a sustained decline in many body organs that may lead to frailty syndrome [4].
