Synopsis
Integrate operative risk, frailty, functional reserve and patient priorities into surgical decisions, and turn risk assessment into specific optimisation, postoperative-care and communication plans.
- Risk depends on the person, the procedure and its urgency; age alone is not a sufficient decision rule.
- Use a validated surgical risk tool to supplement clinical assessment and explain its endpoint, population and uncertainty.
- Assess frailty from usual function and a validated approach, with collateral information where needed; acute illness can distort the bedside impression.
Reasoning priorities
Provide a structured estimate that supplements clinical judgement and supports planning.
Choose a tool validated for the procedure and setting, enter accurate current inputs and identify the outcome and time horizon it predicts. A mortality model does not directly predict loss of independence or quality of life. Do not extrapolate a model beyond its intended population or imply that an estimate is a personalised certainty.
Worked reasoning
An 81-year-old is considering elective major abdominal surgery. They live alone with help for shopping, have recently lost weight and say that remaining at home matters more to them than a small gain in life expectancy. The operation may relieve symptoms but could involve prolonged recovery.
- Establish baseline function, nutritional history, comorbidities and the meaning of the help they receive. Use an appropriate frailty assessment and a validated operative-risk tool, with senior interpretation of the procedure and expected recovery.
- Ask the person to explain their concerns and desired outcome. Discuss expected benefit, major complications, possible increased care needs and alternatives, including what non-operative care would involve and the risks of leaving the condition untreated.
- Arrange targeted optimisation and multidisciplinary input for the identified problems. If frailty assessment supports it, involve comprehensive geriatric assessment rather than treating a score as a yes-or-no permission for surgery.
- The decision is a shared, documented plan that may be to proceed with added support, reconsider timing, choose another treatment or decline surgery. The scenario does not provide enough information to choose one outcome on the patient’s behalf.
- Verify understanding by asking the patient to describe the options and likely recovery in their own words. Record their priorities, remaining questions, review arrangements and who will coordinate optimisation and the final decision.
