[Effectiveness and efficiency of acute geriatric units: A classic topic revisited]

Previous meta-analyses have shown that the hospital admission of older patients in acute geriatric units (AGU) compared to admission to other conventional units, significantly reduced the risk of functional deterioration during hospitalization, increasing the possibility of returning home, with an added reduction in cost of hospitalization. A new meta-analysis on the subject has recently been published in Age and Aging, which adds six new studies to the five clinical trials analyzed in previous meta-analyses. This article analyzes the results of this new meta-analysis, delving into the characteristics of the new studies included and making some considerations on the implications for care in the future development of AGU.
