Embedded geriatric surgical liaison is associated with reduced inpatient length of stay in older patients admitted for gastrointestinal surgery.

The older surgical patient is well known to be at high risk of increased mortality and medical complications in the perioperative period. These occur due to a variety of patient and service related factors. The need for physician support is recognised and liaison models of care can reduce complications and length of stay (LOS) in some surgical specialties. Limited evidence exists evaluating their role in emergency and planned gastrointestinal surgery. We aimed to establish and evaluate a geriatric surgical liaison service for emergency and elective gastrointestinal surgery. We found that embedded geriatrician liaison and process change throughout the surgical pathway was associated with a mean LOS reduction of 3.1 days for all surgical patients aged >60 years (p=0.007). Mean LOS reduction for emergency surgical admissions aged >60 was 4.4 days (p=0.005). Embedded geriatric surgical liaison models of care can be successfully adapted for emergency general and gastrointestinal surgery. In times of financial constraint, reductions in LOS may make modest investment in similar services economically viable.
