Why Your Doctor Told You About the Surgery — But Not About Prehab

The gap nobody talks about

Your surgeon is one of the most highly trained professionals you will ever meet. Years of medical school, residency, fellowship, and specialisation — all of it focused on a single, extraordinarily complex skill: operating on the human body safely and effectively.

That focus is exactly why they don’t talk about prehab.

Surgical training is built around the procedure. The pre-operative consultation covers what the surgery involves, what the risks are, and what to expect in hospital. That is what surgeons are trained to address, and it is genuinely important. But the conversation ends more or less at the operating table. What happens to your body in the weeks before surgery, and the months that follow discharge, sits largely outside the surgical scope — not because it doesn’t matter, but because it belongs to a different discipline entirely.

This is not a criticism of surgeons. It is simply how the healthcare system is structured. Hospitals are organised around episodes of care — you come in, the procedure is performed, you are discharged. Rehabilitation exists in a different part of the system, in outpatient clinics and community settings, often with no direct communication channel back to the operating surgeon. The result is a structural gap, not a personal failing.

There are other factors too. Clinic time is short. The surgical consultation has a lot to cover. Prehab is not yet standard of care in Singapore the way it is becoming in parts of Europe and North America, so there is no protocol prompting the conversation. And frankly, most patients don’t ask — because they don’t know it exists.

The outcome of all this is predictable. Patients arrive for surgery in whatever physical condition they happen to be in. They are discharged with a hospital follow-up appointment and perhaps a generic exercise sheet. Rehabilitation — if it happens at all — begins weeks later, often only when recovery is already stalling.

This is the gap. And it is entirely possible to close it — if you know to look for it.

What is prehab, and why does it matter?

Prehab is structured therapy delivered in the weeks before a planned surgery. It is not aggressive exercise. It is not physiotherapy for a problem that doesn’t exist yet. It is deliberate preparation — getting your body, your home, and your support system ready for the stress of surgery and the recovery demands that follow.

Think of it this way. Two patients go in for the same knee replacement. One has spent the prior three weeks building strength, improving nutrition, and working with a therapist to adapt their home for post-operative mobility. The other has spent those weeks waiting. Both patients wake up from the same procedure in the same hospital. From that point, their recoveries diverge — not because of surgical skill, but because of starting points.

The evidence is consistent across surgery types: patients who do prehab experience shorter hospital stays, fewer complications, faster return to independence, and better long-term outcomes. A 2019 systematic review in the British Journal of Anaesthesia found that multimodal prehab programmes significantly reduced post-operative complications and length of hospital stay across a range of elective procedures.

Why a multidisciplinary team makes the difference

A single physiotherapist can do a great deal. But surgery does not affect only muscles and joints. It affects nutrition, swallowing, daily function, home safety, and emotional wellbeing. No single clinician covers all of that well.

A multidisciplinary team approaches the surgical patient as a whole person. Each discipline contributes something the others cannot.

Physiotherapy addresses the physical demands of surgery and recovery — strength, movement, breathing, swelling, scar tissue, and getting back to full activity. Before surgery, the physiotherapist builds the physical reserve the patient will draw on post-operatively. After surgery, they guide recovery at a pace that respects healing while preventing the rapid deconditioning that sets in with inactivity.

Occupational therapy addresses function in daily life. Not just whether a patient can move a limb, but whether they can dress, cook, bathe, and return to work. The OT closes the gap between what recovery demands and what the patient’s environment and support system can handle — through adaptation, equipment, and retraining. For patients with pre-existing conditions like stroke or cognitive impairment, this role becomes even more central.

Speech therapy is rarely associated with surgery, but its role is significant. Surgery involving the head, neck, chest, or brain frequently affects swallowing and communication. Post-operative patients — particularly the elderly — are at risk of aspiration pneumonia, one of the most serious and preventable post-surgical complications. Speech therapists assess and manage swallowing before and after surgery, protecting the airway and ensuring the patient can eat safely.

Dietetics is perhaps the most underestimated discipline in surgical rehab. The body’s ability to heal is fundamentally a nutritional event. Wound healing, muscle rebuilding, and immune function all depend on adequate protein, micronutrients, and calories. Patients who are nutritionally depleted at the time of surgery heal more slowly, are more susceptible to infection, and lose muscle mass faster post-operatively. A dietician working with the patient before and after the procedure optimises the biological conditions for recovery.

At Lifeweavers, our clinicians have managed these cases in acute hospital settings and have built years of experience practising in the community. That combination matters. Understanding the hospital context means our team can receive a post-discharge patient intelligently, continue care without a gap, and anticipate complications before they become crises.

Five surgery types — what this looks like in practice

1. Wound and skin graft surgery

Wound surgery — debridements, flap reconstructions, skin grafts — is a rehabilitation context most people don’t associate with structured rehab at all. It should be.

Illustrative case: A 68-year-old woman with a stroke history and established contractures in her left arm is scheduled for wound debridement and skin grafting on her forearm.

Her situation involves more than a wound. The spasticity from her stroke is pulling on the surgical site, affecting wound tension and healing. Her contractures mean the limb cannot be positioned neutrally without careful splinting post-operatively. Her stroke history increases her risk of post-anaesthetic cognitive dip and functional decline.

Before surgery, a physiotherapist maintains her range of motion and prepares her respiratory function. An occupational therapist plans positioning strategies and prepares a splint that will protect the graft site while managing spasticity. A dietician reviews her nutritional status — wound healing is protein-intensive, and many elderly patients present with subclinical malnutrition.

After surgery, the same team continues: supporting healing, preventing further contracture formation, and restoring daily function. Without this continuity, the surgical outcome — a healed wound — can coexist with functional decline that leaves the patient worse off overall than before the procedure.

2. Stroke and neurological surgery

Neurological surgery — craniotomies, tumour resection, aneurysm repair — carries unique rehabilitation demands because the organ being operated on is the same one that controls movement, speech, swallowing, and cognition.

Illustrative case: A 55-year-old man undergoes craniotomy for a meningioma. He has mild left-sided weakness and some word-finding difficulty pre-operatively.

The rehabilitation team has a different question from the surgeon: what is this man’s functional baseline today, and how do we protect and restore it around the surgery?

Prehab documents the neurological baseline in detail — strength, balance, speech, swallowing, cognition — so that post-operative changes can be identified early and addressed specifically. The physiotherapist works on balance and strength. The speech therapist assesses swallowing safety pre-operatively and is ready to reassess immediately post-extubation. The OT evaluates home safety and plans for adaptive strategies during the recovery window.

Post-operatively, neuroplasticity — the brain’s ability to reorganise and compensate — is time-sensitive. The rehabilitation team works to maximise this window rather than waiting for a routine referral weeks after discharge.

3. Orthopaedic surgery — joint replacement and fracture

Orthopaedic surgery has the most established prehab evidence base of any surgical category. And yet many Singapore patients arrive for hip or knee replacement with no prior rehabilitation contact at all.

Illustrative case: A 72-year-old woman is scheduled for total knee replacement. She has moderate obesity, poorly controlled diabetes, and lives alone in a HDB flat with no lift access on her floor.

Her diabetes affects wound healing. Her weight increases the physical demand of post-operative mobility. Her living situation means that being unable to manage stairs is not an inconvenience — it is a discharge blocker.

Prehab here is directly practical. The physiotherapist builds leg strength before the surgery date — the stronger the muscles going in, the faster the recovery. The OT conducts a home assessment and arranges adaptive equipment before discharge. The dietician works on glycaemic optimisation and nutritional status. By the time this patient reaches the operating table, her team has already solved many of the problems that would otherwise delay her recovery.

4. Cardiac and thoracic surgery

Cardiac and thoracic procedures — bypass grafting, valve replacement, lung resection — are among the most physically demanding surgeries a patient can undergo. The rehabilitation implications begin before the incision.

Illustrative case: A 63-year-old man with chronic obstructive pulmonary disease is scheduled for a lobectomy for early-stage lung cancer. His baseline respiratory function is already compromised.

Pre-operative physiotherapy focuses on respiratory conditioning — breathing exercises, airway clearance, and inspiratory muscle training to maximise the lung capacity he brings into surgery. Even modest improvements in pre-operative respiratory function translate to meaningfully fewer post-operative pulmonary complications.

After surgery, early mobilisation guided by physiotherapy is the single most important intervention for preventing deep vein thrombosis, pneumonia, and rapid deconditioning. The dietician manages the significant nutritional demands of cardiac healing. The OT prepares the patient for life at home: what activities are safe, how to pace energy, and what to watch for.

For cardiac patients, the gap between hospital discharge and full functional independence is not weeks — it is months. A structured community rehabilitation team bridges that gap.

5. Cancer surgery

Oncological surgery — mastectomy, bowel resection, head and neck procedures, gynaecological cancer surgery — presents the most complex rehabilitation picture. The patient is managing surgical recovery, often concurrent chemotherapy or radiation, and the psychological weight of a cancer diagnosis simultaneously.

Illustrative case: A 48-year-old woman undergoes mastectomy with axillary lymph node dissection for breast cancer. She will begin chemotherapy six weeks post-operatively.

Lymphoedema — chronic swelling of the arm due to lymph node removal — is one of the most functionally limiting long-term complications of breast cancer surgery. It is also largely preventable with early intervention.

A therapist trained in lymphatic drainage can establish a baseline before surgery and educate the patient on early warning signs. Post-operatively, lymphoedema management begins before symptoms become entrenched. The OT addresses shoulder range of motion — axillary dissection restricts the shoulder — and restores functional arm use for daily activities. The dietician supports nutrition through chemotherapy, where appetite suppression and nausea create genuine malnutrition risk. The speech therapist becomes relevant if head and neck cancer or treatment affects swallowing.

The rehabilitation team does not treat the cancer. It treats the person carrying the cancer through surgery and into the rest of their life.

The insurance question: what does your Integrated Shield Plan actually cover?

Here is something most policyholders do not know: if you are hospitalised for surgery and your doctor prescribes physiotherapy, occupational therapy, or speech therapy as part of your post-hospitalisation recovery — linked to the same condition, for restorative rather than maintenance purposes — that outpatient rehabilitation is reimbursable under most Integrated Shield Plans.

This is post-hospitalisation outpatient reimbursement. You pay first, then claim. The standard reimbursement window is 180 days from discharge, extending to 365 days under specific conditions — if treatment is received at a restructured hospital or prescribed by your admitting panel specialist and provided by a panel provider.

In plain terms: a patient recovering from knee replacement, cardiac surgery, cancer surgery, or wound debridement who holds an Integrated Shield Plan should not be making rehabilitation decisions based purely on out-of-pocket cost. The coverage is there. Most people simply don’t know to ask for it.

At Lifeweavers, our care coordinators handle the reimbursement logistics — paperwork, documentation, scheduling, and liaison — so that patients and families can focus on recovery rather than administration.

If you are planning a surgery and hold an Integrated Shield Plan, the right time to ask about rehabilitation coverage is before your admission — not after. Starting the conversation early means the rehabilitation plan can be designed alongside the surgical plan, not as an afterthought.

When should you start?

As soon as you know surgery is coming.

For elective procedures — planned joint replacements, scheduled cancer surgery, known wound procedures — there is typically a window of two to six weeks between surgical confirmation and the operation date. That window is prehab time. It does not need to be intensive. It needs to be intentional.

For urgent or semi-urgent procedures where prehab time is limited, the focus shifts to assessment, baseline documentation, education, and ensuring the post-operative rehabilitation team is positioned before discharge — so that continuity of care begins immediately, not weeks later.

The one scenario that consistently produces the worst outcomes is the one that is still most common in Singapore: surgery happens, the patient goes home, weeks pass, function plateaus or declines, and rehabilitation is eventually sought as a last resort rather than a planned part of recovery.

Surgery fixes the structure. Rehabilitation determines what you do with it.
