People aged over 65 years currently make up 12.5% of the overall U.S. population;7 however they comprise a far greater percentage of hospital inpatients.8 The proportion of the U.S. population aged 65 and older is expected to rise over time.7 By 2030, nearly 1 in 5 residents will be aged 65 or older; by 2050, the geriatric age group is expected to double its population from 2008 (from 38.7 to 88.5 million people).6 The percentage of older adults who are admitted to the hospital is greater than their proportion of the general U.S. population.8 According to the National Center for Health Statistic's National Hospital Discharge Survey, patients aged 65 years and older made up 38% of all hospital discharges and used 46% of all inpatient days in 2001.8 Given the large and growing prevalence of the older adult inpatient, it is undoubtedly beneficial for models to be used in hospital care that tailor care to the geriatric patient.
