Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Delivery of proactive comprehensive geriatric assessment and management (CGA) of patients aged 65 years and over admitted under the vascular surgery service with an expected length of stay > 2 days. The geriatrician and senior vascular nurse will work as a team to undertake CGA at admission, make management recommendations, and follow-through till hospital discharge (i.e. the intervention is delivered from admission up until hospital discharge). The geriatrician will round twice weekly and will liaise with the vascular CNC on other weekdays to implement CGA. There will be no service provision on weekends. A multidisciplinary team meeting will occur weekly with attendance by the geriatrician that focuses on discharge planning. Provision of education and training in CGA and delirium for nursing staff as part of in-service education on the ward; this will be delivered by the geriatrician, vascular clinical nurse consultant, vascular clinical nurse educator, and falls and delirium clinical nurse consultant. Patient and carer education regarding delirium and falls, and strategies to prevent these with distribution of consumer information pamphlets which are available from the Agency for Clinical Innovation.
This is anticipated to be an ongoing service.
Patient recruitment in the post-implementation phase will conclude after 8 months.
Intervention fidelity will be assessed as the proportion of patients who received comprehensive geriatric assessment and management by the geriatrician and/or vascular CNC.

Outcomes
Primary outcome [1] 321192 0
Proportion of participants who experience at least one of the following geriatric syndromes during admission: delirium, functional decline at discharge, constipation, pressure injury or falls Delirium assessment based on face to face CAM and baseline cognitive screen. As well as based on notes and nursing staff observation. Functional decline will be assessed as an increase in ADL by 1 point or more between admission and discharge from the vascular surgery team as assessed using the KATZ ADL scale. Falls, constipation and pressure injury incidence will be sourced from patient medical records using predefined criteria developed by the study investigators based on a literature review and expert opinion. Delirium is the geriatric syndrome of most interest as has been associated with multiple adverse long-term consequences..

Summary
Brief summary
Older patients undergoing surgery are at an increased risk of post-operative complications including geriatric syndromes such as delirium, functional decline and falls.. The Aged Care Department at Concord Hospital will introduce a novel co-management model of care for older adults admitted under the vascular surgery service. As part of the new service proactive comprehensive geriatric assessment and management will be undertaken by the geriatrician who will work collaboratively with the vascular surgery nursing staff and team. Using a prospective before and after study design, this research will evaluate the impact of this innovative, interdisciplinary and patient-centred model of care on important health outcomes.
