Although the aging population will affect all areas of health care, the ED is likely to be disproportionately affected. In 2002, approximately 58% of 75-year-olds had at least one visit to an ED, as compared to 39% of those of all ages, and ED use increased with increasing age.3 Once in the ED, older patients are more likely to have an emergent or urgent condition, be hospitalized, and be admitted to a critical care unit.4 In addition, older patients are also more likely to receive a greater number of diagnostic tests, spend longer times in the ED, and have higher charges for their ED services than younger patients.5
The Disconnect Between Emergency and Elder Care
The ED is a unique environment where highly specialized care is delivered to the acutely ill and injured and safety net care is provided to disenfranchised and vulnerable populations. Although studies have begun to demonstrate disparities in care for older adults, most have focused on specific diseases or conditions6 and have not looked specifically at how ED care and environmental factors may be associated with patient outcomes. Nonetheless, there are indications that the current model of ED care may not be meeting the needs of older adults. After an ED visit, older adults are at greater risk for medical complications, functional decline, and poorer health-related quality of life than they were before.7,8 Up to 27% of older adults discharged home from the ED experience revisit, hospitalization, or death within 3 months after discharge.9 In addition, a survey of older patients discharged from an inner-city ED revealed that most believed that ED staff were not attentive to their questions or needs.10
The special care needs of older adults unfortunately are not aligned with the priorities of how ED physical space is designed and how ED care is rendered. Space is planned with the intent of quick patient evaluation and turnover; the physical layout of a traditional ED is focused on maximal use of resources. Privacy is forsaken at the expense of improving throughput so that curtains rather than walls serve as barriers between beds in an open-spaced ED, allowing for greater staff maneuverability and placement of multiple patients in shared bays during periods of crowding. Given high hospital occupancy rates, patients may lay on narrow, thinly mattressed stretchers for hours, even days, while awaiting diagnostic tests or unavailable hospital beds, thus increasing the risk for pressure ulcers during their hospitalization. Floors in the ED typically consist of slippery linoleum or hard vinyl components designed for easy cleanup of spills and body fluids, creating fall hazards for geriatric patients with gait impairments. Because EDs are often located on ground floors of hospitals, they are usually windowless to preserve patient privacy, with lighting limited to glaring overhead fluorescent lamps, which may promote disorientation in cognitively impaired older adults not exposed to diurnal changes. Finally, EDs are rarely quiet. Noise, resulting from continuous clanging of monitor alarms, the chatter of clinical staff, and the clamor of other patients in the same physical space, is constant—contributing to communication difficulties for patients who may be hearing impaired and possibly increasing the risk of developing or worsening delirium.
There is also a mismatch between how ED care is currently rendered and how care could optimally be delivered to older adults. Rapid triage and diagnosis may be impossible in older patients with multiple comorbidities, polypharmacy, and functional and cognitive impairments who often present with subtle clinical symptoms and signs of acute illness. The time pressure to make a fast diagnosis can increase the risk of incorrect or missed diagnoses. Unaccompanied patients, who may not be able to advocate for themselves because of delirium, dementia, or sensory impairments, compete with younger more vocal adults —often unsuccessfully—for the attention of busy clinical staff. Finally, to reduce the risk of falls from patients ambulating to restrooms and because of limited staff time to change diapers or bedpans, bladder catheters are often inserted, increasing risks for developing delirium and infection.11,12 As eloquently and bluntly stated in a commentary calling for a new model of emergency care for geriatric patients, our current system of ED care is “not designed for older people.”13
Geriatric Emergency Department Interventions
In response to the needs of the growing number of older adults seen in EDs, Geriatric Emergency Department Interventions (GEDIs) that would include better clinical staff education in geriatric emergency medicine and nursing care, evidence-based protocols for common geriatric syndromes, and ideally, appropriate structural modifications are proposed. Protocols, trained staff, and physical modifications targeted at the geriatric patient in inpatient settings have already been shown to successfully reduce the risk of delirium, iatrogenic complications, cost, hospital length of stay, and transfer to long-term care facilities, while increasing patient and provider satisfaction and preserving patient function.14–17 It has recently been shown that these programs are replicable in community hospitals, demonstrating the widespread applicability and effectiveness of geriatric-focused interventions for inpatient geriatric care. The proposed GEDIs would initially be targeted toward patients aged 65 and older and could potentially be implemented (incrementally, depending on fiscal, physical, and demographic constraints of hospital systems) in all types of EDs.
For EDs that are being newly constructed or renovated, physical space would be designed with the intent of optimal care delivery to the complex geriatric patient. Ideally, sky or ceiling windows would be installed to provide access to natural lighting, and hospital recess lamps would be dimmed during the evening to follow diurnal patterns18 and potentially diminish the risk of patients becoming disoriented to time. The use of sound-proof curtains between open bays throughout the ED might help to preserve privacy19,20 and provide a more acoustic-friendly environment. Optimally, patients would rest on stretchers with pressure-reducing mattresses or, if able to sit, in reclining chairs during their ED evaluation.21,22 To assist in navigating the ED for those who are ambulatory, walls and hallways would have support rails, and floors would have “aisle” lighting.23 Additionally, floors would be tiled with nonskid, level surfaces to aid in mobility and decrease the risk of injuries for patients at risk of falls within the ED.23 Improvements would be made in signage, including boards with hospital and clinical staff names visible in large print, large-faced clocks, and calendars that would be plentiful and visible from all patient bays. Visual aids (e.g., glasses or magnifying lenses), adaptive equipment (e.g., telephones with large, illuminated keypads; fluorescent tape on call bell), and hearing devices (e.g., portable amplifying devices24 and special communication techniques) would be available to all patients.14 Finally, ambient temperatures would be adjusted for a more-comfortable environment to all patients seen in the ED.
For EDs with limited budgets and space, less-expensive changes could be made incorporating some of the above modifications. Upon arrival, older adults would receive a “GEDI package” at triage consisting of some or all of pressure-reducing egg-crate padding, a hearing device, and a magnifying lens. Removable rubber mats would be placed near the patient's stretcher along with a commode to minimize the risk of falls. Less-expensive structural changes suggested above, such as the soundproof curtains, better signage, and minimizing excess noise (using cell phones rather than overhead announcements, providing ear phones to patients watching televisions) could be implemented throughout the ED at relatively little cost.
With the GEDIs, practice patterns in ED patient care would be modified for the screening and assessment of conditions specific to the geriatric patient population. At triage, older adults would be evaluated for signs of cognitive impairment,25 risk of hospitalization, or having a return ED visit using short validated instruments such as the Identification of Seniors At Risk.26 Given the high prevalence of delirium in hospitalized older adults, all patients would be formally tested for this condition during their clinical assessment. Family members would be allowed to accompany patients to provide physical assistance for those with functional impairments or additional background and history to the clinical staff for those who are cognitively impaired. Protocols for pain management and other diagnostic algorithms would be modified for older patients with conditions such as hip fracture, abdominal pain, pressure ulcers, urinary retention, and syncope. Physical restraints would not be used,11 and any devices or equipment that serve to reduce mobility or tether patients to beds (e.g., bladder catheters, telemetry leads, pulse oximeters) would be minimized and used only if medically indicated. For patients being discharged, functional impairment screening and abbreviated comprehensive geriatric assessments would be implemented to assist in determining whether the patient was appropriate for discharge, to improve functional outcomes, and to decrease return visits and hospitalizations. Interdisciplinary teams of social workers and an ED-based nursing discharge coordinator would coordinate such transitions of care from the ED to the home or nursing home for follow-up by primary care physicians or to community services.27,28 For a summary of proposed GEDIs and their goals, see Table 1.
