Gout nursing care: what to assess and what to do first

Recognising it at the bedside

The patient presents with sudden, severe pain in a single joint, most often the first metatarsophalangeal joint of the big toe. The joint is hot, swollen, dusky red, and exquisitely tender, often to the point that a bedsheet touching it is unbearable. Onset is typically overnight, waking the patient from sleep.

Fever and an elevated white cell count can accompany an acute flare, which is where the picture gets confused with septic arthritis. Ask about triggers: alcohol, purine-rich food, dehydration, recent surgery, or starting a diuretic. A history of previous identical episodes in the same or other joints strongly supports gout over a first-time infection.

Why the classic presentation misleads

A hot, swollen, febrile joint looks like septic arthritis, and that possibility has to be ruled out before gout is assumed, because a missed joint infection can destroy cartilage within days. The two are distinguished by joint aspiration and synovial fluid analysis, not by appearance alone.

Serum uric acid is also unreliable during the attack itself. Many patients have a normal or even low uric acid level in the middle of an acute flare, because the acute inflammatory response shifts urate handling. A normal level at the bedside does not rule gout out, and a nurse who anchors on that single value risks delaying appropriate pain treatment while chasing the wrong diagnosis.

Priority nursing actions

Elevate and rest the affected joint, keep it uncovered or under a bed cradle so nothing touches it, and apply ice as ordered. Administer prescribed colchicine or an NSAID such as indomethacin promptly, since these are first-line for acute treatment and work best started early in the attack.

Do not give or start allopurinol during an acute flare. Allopurinol lowers uric acid over time, and the sudden shift in serum urate it causes can mobilise crystals and worsen the current attack or trigger a new one. If the patient is already established on allopurinol, the general teaching is to continue it rather than stop it, since stopping mid-course causes its own urate swings, but new initiation waits until the attack has settled.

Assess renal function before NSAIDs are given, since acute kidney injury or CKD changes the risk-benefit picture, and corticosteroids become the safer alternative when NSAIDs are contraindicated.

Labs and diagnostics to expect

Joint aspiration with synovial fluid analysis under polarised light microscopy is the definitive test. Gout shows negatively birefringent, needle-shaped monosodium urate crystals; this also confirms the joint is not septic by sending fluid for culture and cell count.

Serum uric acid is drawn but interpreted with caution during a flare for the reasons above; it is more useful once the attack resolves, to guide long-term urate-lowering therapy. Renal function tests (creatinine, eGFR) matter both because impaired clearance predisposes to gout and because they determine which acute and prophylactic drugs are safe. Imaging is not routinely needed for a first typical attack but may be used if the diagnosis is unclear.

Complications and their early signs

Untreated or poorly controlled gout leads to tophi, chalky deposits of urate crystals in soft tissue and around joints, which can ulcerate through skin and become infected. Watch for firm, whitish nodules near the elbows, ears, or finger joints in patients with a long history of flares.

Recurrent attacks cause chronic joint damage and deformity if urate levels are never brought under control. Gout also correlates strongly with uric acid kidney stones and, over time, chronic kidney disease, so flank pain or haematuria in a gout patient warrants prompt follow-up. Sudden worsening with high fever, chills, and joint effusion should always prompt reassessment for superimposed septic arthritis rather than assuming it is simply another gout flare.

Teaching that changes outcomes

Teach the patient to avoid high-purine foods such as organ meats, shellfish, and red meat, and to limit alcohol, particularly beer, which raises urate levels independently of its calories. Adequate hydration helps urate excretion and reduces stone risk.

The most important teaching point is the sequencing of drugs: colchicine and NSAIDs treat the attack, allopurinol prevents future ones, and starting or adjusting allopurinol during an active flare can make things worse. Patients on long-term allopurinol should understand not to stop it just because they feel fine, and to report any rash immediately, since allopurinol hypersensitivity syndrome is rare but serious. Reinforce that missed doses of prophylactic therapy, not the drug itself, are the usual reason flares recur.
