An interdisciplinary model to enhance care of older patients undergoing vascular surgery

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Pre-intervention cohort receives care from vascular surgical team, including referral to allied health and medical services as required, according to usual practice.
Intervention is a complex system change which directly engages team members of the intervention ward in an evolving redesign of care processes to meet the following broad goals:
1. Proactive medical consultation: consistent medical registrar supervised by a general physician will review older patients pre-operatively where feasible and throughout the post-operative course in collaboration with the surgical team to optimise management of comorbidities, until the time of discharge
2. Enhanced multidisciplinary care team focus to support implementation of cognitive orientation/stimulation, feeding assistance and exercise/ambulation, achieved using holistic facilitation based on the PARIHS framework
3. Staff and patient education regarding delirium, functional decline and malnutrition and strategies designed to minimise them, using small group interactive staff teaching (initally 30 minutes per week for 5 weeks, repeated every 10-12 weeks based on staff rotations) and staff and patient brochures
Post-intervention cohort data will be collected after 6 months (August-December 2013) or when intervention is considered mature. Intervention will continue throughout the post-intervention data collection period.

Outcomes
Primary outcome [1] 288021 0
Functional decline, defined as increase in number of basic activites of daily living (based on Katz scale) for which the patient requires human assistance (patient report supplemented as necessary by nurse report)
Timepoint [1] 288021 0
Functional status measured at multiple time points (3 times per week) during hospitalisation will be compared to pre-admission functional status using trajectory modelling

Delirium (Confusion Assessment Method, CAM)
Timepoint [2] 288022 0
Delirium is assessed at multiple time points (3 times per week) during hospitalisation and will be converted to a binary variable
