Background: older people undergoing elective surgery have significant post-operative problems prolonging hospitalisation.
Objective: to design, embed, and evaluate an evidence-based comprehensive geriatric assessment (CGA) service for at-risk older patients undergoing elective surgery.
Setting: urban teaching hospital.
Subjects: elective surgical patients aged 65+.
Intervention: multidisciplinary preoperative CGA service with post-operative follow-through (proactive care of older people undergoing surgery [‘POPS’]).
Methods: observational cohort study and multilevel surveys (development and modelling phase). Prospective ‘before and after’ comparison (exploratory evaluation).
Results: findings from the development phase showed high levels of preoperative co-morbidity, no multidisciplinary preoperative input, and multiple potentially preventable post-operative problems delaying discharge in older elective surgery patients. Comparison of 2 cohorts of elective orthopaedic patients (pre-POPS vs POPS, N = 54) showed the POPS group had fewer post-operative medical complications including pneumonia (20% vs 4% [p = 0.008]) and delirium (19% vs 6% [p = 0.036]), and significant improvements in areas reflecting multidisciplinary practice including pressure sores (19% vs 4% [p = 0.028]), poor pain control (30% vs 2% [p<0.001]), delayed mobilisation (28% vs 9% [p = 0.012]) and inappropriate catheter use (20% vs 7% [p = 0.046]). Length of stay was reduced by 4.5 days. There were fewer delayed discharges relating to medical complications (37% vs 13%) or waits for OT assessment or equipment (20% vs 4%).
Conclusion: a proactive evidence-based CGA service for at-risk older elective surgical patients was developed according to MRC framework for complex interventions. Pre/post comparison in elective orthopaedic patients showed improved (within methodological limitations) post-operative outcomes indicative of better clinical effectiveness and efficiency, and contributed to the service obtaining mainstream funding. Informed by the present study, a randomised controlled trial is ongoing.
