Geriatric assessment by default for every patient over 70 starting cancer treatment

A short structured check of memory, mobility, nutrition and medicines before treatment cuts serious side effects in older patients without reducing benefit. It should be automatic, not optional.

Randomised trials (GAP70+, GAIN, and others) showed that geriatric assessment with management recommendations reduces grade 3 or higher toxicity in older patients receiving chemotherapy, and ASCO guidelines recommend it. Uptake remains low because it is seen as extra work. Embedding a validated screening tool (such as G8) in intake, with automatic full assessment and management recommendations for positive screens, delivered by nurses, would make it the default.

Hypothesis
Default geriatric assessment will reduce grade 3 or higher treatment toxicity in patients over 70 by at least 20% and reduce unplanned admissions, without reducing treatment completion for curative-intent therapy.
Rationale
Level 1 evidence of benefit exists; the failure is implementation, which defaults address.
What would test it
A stepped-wedge implementation across 20 centres with toxicity, admissions, treatment completion, and functional decline at six months as endpoints.
Maturity
being tested at scale
Who has to act
clinic
Cost to try
Small (under $1M)
