Symptom Control Therapy

Symptom Control Therapy is a palliative care treatment that focuses on relieving the discomfort caused by a serious illness, rather than trying to cure the illness itself.

When a disease such as advanced cancer, heart failure, or severe lung disease causes pain, breathlessness, nausea, fatigue, or other distressing symptoms, the body is under constant stress. Symptom Control Therapy uses a combination of medicines, physical techniques, and emotional support to reduce that burden. The goal is to help the person feel as comfortable and functional as possible, day to day.

Symptom Control Therapy is used when a serious or life-limiting illness produces symptoms that are difficult to manage on their own. It can be given alongside curative treatment, or as the main focus of care when curative options are no longer suitable.

• Advanced cancer causing pain, nausea, or loss of appetite
• End-stage heart failure causing breathlessness and swelling
• Chronic obstructive pulmonary disease (COPD — a long-term lung condition that makes breathing difficult) in its severe stages
• Advanced kidney failure causing fatigue, itching, and fluid build-up
• Neurological (brain and nerve) diseases such as advanced motor neurone disease or Parkinson's disease
• HIV/AIDS at a late stage causing multiple distressing symptoms
• Any serious illness where pain or other symptoms are not well controlled by standard treatment

There are situations where this specific therapy approach may need to be adjusted or where certain symptom-control methods may not be appropriate.

• Some medicines used to control symptoms may not be safe for patients with severe liver or kidney problems — the care team will assess this carefully
• Patients who are still pursuing aggressive curative treatment may need a modified approach that does not interfere with that treatment
• Certain physical techniques, such as nerve blocks (injections that switch off pain signals from a specific area), may not be suitable if there is infection or bleeding risk at the injection site

Symptom Control Therapy is generally considered a low-risk approach, because each element of the plan is chosen carefully for the individual patient; however, some medicines and procedures used within it carry their own side effects.

• Drowsiness or sedation from pain-relieving medicines, especially opioids (strong pain medicines)
• Constipation (difficulty passing stools), a very common side effect of opioid medicines
• Nausea or vomiting from certain medicines used to relieve pain or anxiety
• Dry mouth, dizziness, or confusion, particularly in older or frail patients
• Risk of infection at the site of any injection used for nerve blocks or other local procedures
• Accidental over-sedation if medicine doses need adjustment — the team monitors for this closely
• Psychological distress if symptom control is incomplete or if emotional support needs are not fully met
• In rare cases, certain procedures such as nerve blocks may cause temporary weakness or numbness in the affected area

Preparation for Symptom Control Therapy is different from preparation for surgery. There is usually no fasting required and no single procedure to prepare for. Instead, preparation centres on giving the care team a complete picture of the patient's symptoms, current medicines, and personal wishes.

Before the plan begins, the team will typically ask the patient to do or consider the following:

• Bring a full list of all current medicines, including herbal supplements and vitamins, to the first appointment
• Be honest and detailed when describing all symptoms — their location, severity, what makes them better or worse, and how they affect daily life
• Share personal and cultural preferences about care, including any wishes about where to receive treatment (home, hospice, or hospital)
• Avoid starting or stopping any medicine without guidance from the care team, as some combinations can interact
• If alcohol is consumed regularly, tell the team, as this can affect how certain medicines work
• Smokers may be advised by the team about whether smoking affects their specific symptom management

The team will usually carry out several assessments before finalising the plan. These may include:

• A detailed symptom assessment using a standardised scoring tool to measure pain, fatigue, breathlessness, and mood
• Blood tests to check liver and kidney function, which affects which medicines are safe to use
• A review of any recent imaging (CT, MRI, or X-ray) related to the underlying illness
• A psychological assessment to understand emotional distress, depression (persistent low mood), or anxiety
• A social and family assessment to understand the support available at home

Once assessments are complete, the care team creates an individualised symptom control plan. The typical steps at the first session are:

• 1. A palliative care specialist meets with the patient and, if the patient agrees, with family members
• 2. The team reviews all assessment results together with the patient
• 3. Treatment goals are agreed — for example, reducing pain to a level where the patient can sleep, or managing breathlessness enough to allow short walks
• 4. Medicines, doses, and schedules are prescribed and clearly explained
• 5. Non-medicine approaches — such as positioning aids, breathing exercises, or relaxation techniques — are introduced if relevant
• 6. A contact plan is given so the patient or carer knows who to call if symptoms worsen suddenly

Aftercare for Symptom Control Therapy is ongoing rather than a single recovery period — the plan is reviewed and adjusted regularly as the patient's condition changes. The care team, which may include palliative care doctors, nurses, social workers, and psychologists, stays involved over time.

• Follow-up appointments are scheduled regularly, usually more frequently at first, then adjusted based on how well symptoms are controlled
• Patients and carers are encouraged to keep a simple symptom diary to help the team spot patterns and adjust the plan
• If medicines cause troublesome side effects, the team will usually adjust the type or dose rather than stopping treatment suddenly
• Wound or injection site care instructions will be given if any procedure such as a nerve block has been performed — signs of infection to watch for will be explained
• Emotional and psychological support, including counselling (talking therapy) or spiritual care, is considered part of aftercare and should be requested if needed
• Family members and informal carers (people who help at home) may be offered guidance and support, as caring for someone with serious illness can be exhausting
• If care is being provided at home, a community palliative care nurse or home-visit doctor may be arranged to monitor the patient between appointments
• Patients are advised to avoid making sudden changes to their medicine routine without consulting the care team, as this can cause symptoms to flare
• Lifestyle adjustments — such as diet changes to help with nausea, gentle activity as tolerated, and sleep hygiene (habits that promote restful sleep) — are discussed based on the individual's situation
• An emergency contact or out-of-hours care line is usually provided so that sudden changes in symptoms can be addressed promptly
