Treating depression before surgery helped older patients, almost entirely in the cancer group
Depression and anxiety are common before major surgery in later life and rarely addressed. Randomizing 306 patients over 60 found a benefit that was not spread evenly across operations.
- Depression and anxiety scores fell further in the treated group at three months.
- Cancer surgery patients accounted for most of the effect.
- Patients having joint or bone surgery showed no benefit at all.
- The intervention combined psychological support with medication review.
- 306 patients aged 60 and over, randomized evenly to treatment or enhanced usual care.
Surgery in later life comes with a mental health problem that nobody is responsible for. The surgeon is managing the operation, the anesthetist the risk, and the low mood or dread a patient carries in with them belongs to neither.
That matters beyond comfort. Depression and anxiety are common among older adults undergoing surgery and are associated with worse recovery afterwards.
What the perioperative mental health package involved
Writing in JAMA Network Open, researchers randomized 306 adults aged 60 and over, all scheduled for cardiac, cancer or orthopedic surgery, and all already scoring at a level that would concern a clinician.
Half received a combined intervention: psychological support alongside a proper review of any psychiatric medication, delivered around the operation. Half received enhanced usual care, meaning self-management materials rather than nothing. Previously effective tailored perioperative mental health interventions were lacking, which is the gap the trial addresses.
How far depression and anxiety scores fell
At three months, the treated group scored lower on the combined depression and anxiety measure, by a little over two points against a starting score of about eighteen and a half.
That is a real difference and a modest one. On its own it would be a quiet result.
Why cancer surgery patients drove the benefit
The average conceals three very different operations.
Among patients having cancer surgery, the difference was close to five points, which is the range clinicians treat as something a patient would actually notice.
Among cardiac surgery patients it was about two and a half points, in the same direction but not distinguishable from chance at this size.
Among orthopedic patients it was slightly negative. No benefit at all.
How much weight the surgery subgroups can carry
The temptation is to conclude the treatment works for cancer patients and not for joint replacements, and the trial does not support a conclusion that firm. Each subgroup holds about a hundred people, subgroup analyses are exploratory, and a contrast this clean can appear by chance.
What can be said is that the overall effect was not spread evenly, and the pattern has a plausible shape. Distress before cancer surgery is tied to the diagnosis, the uncertainty and the prognosis, none of which the operation resolves. Distress before a knee replacement is often about pain and immobility, which the operation does resolve.
If that account is right, psychological support helps most where the surgery itself does not treat the cause of the distress. That is testable, and untested here.
What a single-blind surgery trial can show
Single-blind, so patients knew which group they were in, and a self-reported mood questionnaire is exactly the outcome most vulnerable to that. The comparison was against enhanced usual care rather than nothing, which makes the test harder and the result more credible.
Three months is enough to see a mood change and not enough to see whether it translates into the outcomes that motivated the question: complications, length of stay, whether people get back to their lives.
What this changes before surgery in later life
Depression is more than a feeling of being sad or irritable for a few days, and it is treatable in a population where a great deal else is not.
The practical value here is smaller than the trial’s framing and still real. Before major surgery in later life, mood is worth asking about, and the asking appears to be worth most in the patients whose distress the operation will not fix.

What did the trial find?
Among 306 adults (mean age 68.5 years; 68.3% female; 153 per group), baseline PHQ-ADS score was 18.5. At three months there was a significant decrease in the intervention group compared with enhanced usual care (mean difference 2.20; 95% CI, 0.16-4.24; P = .03). Effects varied by surgery: oncologic 4.93 (1.51-8.36; P = .005), cardiac 2.68 (-0.98 to 6.35; P = .15), orthopedic -1.11 (-4.62 to 2.40; P = .54).
What was the intervention?
A combination of psychological management and review of psychiatric medication around the time of surgery. The comparison group received enhanced usual care, meaning materials for managing symptoms themselves rather than nothing at all.
What is the PHQ-ADS?
A questionnaire combining depression and anxiety items into one score. It is used because the two conditions overlap heavily and treating them as separate targets before surgery is often artificial.
Is a 2.2 point difference meaningful?
It is modest on a scale where the group started at 18.5. The more informative figure is the cancer surgery subgroup, where the difference was closer to five points, which is the size clinicians generally regard as noticeable to a patient.
Why would cancer surgery patients benefit most?
The trial does not establish why. One plausible reading is that distress before cancer surgery is driven by the diagnosis and its uncertainty, which is exactly what psychological support addresses, while distress before a planned joint replacement may be driven by pain and disability that surgery itself resolves.
Should the subgroup results be trusted?
With caution. Subgroup findings are exploratory by nature and each contains roughly a hundred patients, so the contrast between them could reflect chance. It is a lead for a larger trial rather than a basis for restricting the treatment.
What should an older patient facing surgery do?
Raising low mood or anxiety with the surgical team before the operation is reasonable and rarely offered unprompted. Treatment decisions belong with clinicians who know the case. This is general information rather than medical advice.
