NICHE MODELS
Geriatric Resource Nurse (GRN) Model
The GRN model has been implemented in many specialty areas, including critical care, oncology and emergency departments. This requires "fine tuning" clinical knowledge to provide GRNs witht focused educational preparation and training, as well as practice tools to provide expert care in these specialty areas. Involvement in specialty organizations provides GRNs the opportunity to shape conference and journal content to reflect the needs fo older adult patients. The Hartford Institute's Geriatric Competence of Speciality Nurses initiative supports specialty nurses associations as vehicles for assuring the geriatric competence of specialty nurses. See ConsultGeriRN.org for further information.
An Acute Care of the Elderly Medical-Surgical Unit (ACE Unit)
The ACE model was formally developed at University Hospitals of Cleveland in conjunction with the Frances Payne Bolton School of Nursing at Case Western Reserve University. A 29-bed medical- surgical specialty unit was renovated and dedicated as an Acute Care of the Elderly (ACE) unit to prevent functional decline in this targeted group of patients.Consistent with the original concept, the NICHE ACE model designates a specific unit or a section of a unit in order to deliver interventions known to improve the clinical outcomes of older adult patients. Key elements of an ACE unit include environmental adaptations for older patients (e.g., flooring to decrease visual glare and noise, enhanced lighting, clocks and calendars in patient rooms, communal area for activities and meals), staff with special expertise in geriatrics, and an interdisciplinary team focused on preventing geriatric syndromes.
The ACE model promotes collaborative team building and nurse-initiated clinical protocols of care. The geriatric medical director and geriatric advanced practice nurse provide clinical leadership. The ACE model also fosters hospital-wide improvement of nurses’ geriatric knowledge by serving as a resource center for care of older adult patients.
The NICHE approach to the ACE Model focuses on the role of nursing in improving care for hospitalized elders. Specifically, we highlight the role of the geriatric advanced practice nurse and the Geriatric Resource Nurse (GRN). We believe all nurses working on an ACE unit should receive GRN-level education.
Whether or not you decide to implement the ACE model in your hospital, there are some ACE concepts that can be disseminated throughout the hospital to make the environment more elder friendly. These include: geriatric training of nurses and all other direct care providers, a physical environment that addresses age-related changes, and interprofessional teams.
