The phlebitis threshold for surveillance & reporting
For audit and surveillance purposes, a VIP Score of 2 or above is classified as phlebitis. Score 1 is not counted as phlebitis but should trigger increased vigilance. Scores of 3, 4, and 5 indicate a level at which clinical practice standards should be carefully reviewed.
Clinical Rationale
Why a graded scale — not a simple yes/no — matters
Recording phlebitis as merely present or absent strips away the clinical information that drives decisions. The VIP Score's 0–5 structure is intentionally designed to preserve that nuance.
❌ Binary (Yes / No)
Phlebitis: Yes or No
- ✗No distinction between mild redness and advanced thrombophlebitis
- ✗Cannot detect early warning signs before intervention is needed
- ✗Audit data obscures clinical performance — a ward with score-2 phlebitis looks the same as one with score-5
- ✗Clinicians cannot demonstrate improvement over time
- ✗Provides no actionable threshold for decision-making
✔ Graded Scale (0–5)
VIP Score
- ✓Captures the full clinical spectrum from healthy site to advanced thrombophlebitis
- ✓Score 1 triggers early review before phlebitis is established
- ✓Score 2 is the validated, evidence-based intervention threshold
- ✓Enables trend tracking: was the site deteriorating or improving?
- ✓Supports meaningful audit, benchmarking, and quality improvement
Clinically actionable at every grade
Each score from 0 to 5 carries a defined clinical response. There is no ambiguity — score 2 means remove the cannula; score 5 means initiate urgent treatment. A binary result cannot deliver this level of decision support.
Enables meaningful audit
Phlebitis rates calculated using a graded scale reveal the true severity distribution across a ward or organisation. Benchmarking against national standards requires granular data — a yes/no approach collapses this into a single, uninformative figure.
Identifies deterioration early
Score 1 is not phlebitis — but it is a warning. The scale allows clinicians to act before the threshold of established phlebitis is reached, potentially avoiding the need for cannula removal altogether through timely investigation of the cause.
Supports documentation & legal clarity
A documented score provides objective, reproducible evidence of site status at each assessment. A numerical record is far more defensible in case of patient complaint or adverse event review than a narrative description.
International impact
The VIP Score has become a widely adopted tool for peripheral IV assessment across acute and community settings in many countries, featuring in local policies, national guidance and international education resources.
Drives quality improvement
Successful implementation should produce consistently low scores. Rising scores are an objective signal that practice, device choice, or standards warrant review — something a binary system can never reveal.
Step-by-step guide
How to use the VIP Score
The VIP Score is quick to apply at the bedside. Follow these steps at each assessment to ensure consistent, reliable scoring.
1
Prepare for assessment
Wash hands and don appropriate PPE before approaching the patient. Explain what you are doing and obtain consent. View the peripheral IV cannula site fully — remove any dressings that obscure the insertion point or surrounding skin.
2
Inspect the site visually
Examine the skin around the cannula insertion point in good light. Look for: redness (erythema), swelling (oedema), such as induration or hardening, a visible red streak along the vein, or any purulence at the insertion point.
💡 Compare with the contralateral limb to help identify subtle erythema, particularly in patients with darker skin tones or pre-existing skin conditions.
3
Palpate and question the patient
Gently palpate along the vein path proximal to the cannula tip. Ask the patient whether they have pain or tenderness at or near the site. Note whether palpation reveals a cord-like hardening (palpable venous cord) and whether pain is localised to the insertion point or extends along the vein.
4
Assign a score using the VIP table
Using the signs identified, select the score that most accurately matches the clinical picture. Start from score 0 and work upwards — assign the highest score supported by the signs present.
💡 Score 2 requires any two of: pain, erythema, or swelling. If in doubt, score higher rather than lower.
5
Take the action indicated by the score
Act on the score immediately. Scores 0–1: document and continue monitoring. Score 2 and above: remove the peripheral IV cannula, document the score, and arrange re-siting if ongoing IV access is required. Scores 3–5: consider treatment for established phlebitis or thrombophlebitis and escalate to a senior clinician.
6
Document accurately
Record the numerical VIP score — not a description — in the patient's documentation at every assessment, with date, time, and clinician name. If the cannula is removed, note the score at removal, cannula site, and action taken.
💡 Avoid documenting "site looks fine" without a numerical score. Numbers support audit, handover, and legal defensibility in a way that narrative descriptions cannot.
Recommended assessment frequency
Assessment frequency should match clinical need. The following is a general guide based on current evidence and best practice.
| Setting / circumstance | Minimum frequency |
|---|---|
| All patients with a peripheral IV cannula in situ | At each care contact / shift minimum |
| Continuous IV infusions running | Before, during, and after the infusion |
| Vesicant or irritant drugs (e.g. amiodarone, vancomycin, potassium) | Every 1–2 hours during infusion |
| Paediatric patients | Every hour, or per local policy |
| VIP Score 1 on previous assessment | Increase to hourly or as clinically indicated |
Evidence-based. Clinically validated.
The VIP Score was originally developed by Jackson (1998) and has been widely adopted in clinical guidelines and national standards across the UK and beyond. Its 0–5 structure improves consistency of assessment, supports surveillance data collection, and reduces preventable phlebitis rates.

Frequently asked questions
Common questions about the VIP Score
Answers to the questions most frequently raised by clinicians, educators, and ward teams implementing the VIP Score in practice.
VIP stands for Visual Infusion Phlebitis. The name reflects how the score is applied: through visual inspection and clinical assessment of the peripheral IV cannula site, in the context of intravenous infusion therapy.
A VIP Score of 2 or above indicates phlebitis and the peripheral IV cannula should be removed. Score 2 is the validated intervention threshold. At score 1, the cannula may remain in situ subject to clinical review, but increased vigilance and investigation of the cause is required.
No. For surveillance and audit purposes, a score of 1 is not counted as phlebitis. However, score 1 should never be dismissed — it is a clinically meaningful signal to increase assessment frequency and investigate potential causes before phlebitis becomes established.
All three represent established, progressive phlebitis requiring prompt action:
- Score 3: Pain along the vein path, erythema, and induration.
- Score 4: Score 3 signs plus a palpable venous cord. Signs are extensive.
- Score 5: Score 4 signs plus systemic pyrexia. Requires urgent treatment escalation.
At every care contact and at least every shift. When a continuous infusion is running, assess before, during, and after. For irritant or vesicant drugs, assess every 1–2 hours during infusion. If a previous assessment returned score 1, increase frequency accordingly.
Always document the numerical VIP Score. A number is unambiguous, reproducible, and supports audit data collection. Narrative descriptions are subjective and cannot be compared across clinicians, shifts, or time points.
- Document the score, site location, and time of removal.
- Apply gentle pressure and observe for bleeding.
- Re-site in a different location and limb if ongoing IV access is needed.
- For scores 3–5, consider whether treatment for phlebitis or thrombophlebitis is indicated and escalate to a prescriber if required.
- Review whether the drug, administration route, or dwell time contributed to phlebitis.
Phlebitis surveillance counts episodes where the VIP Score reached 2 or above as reportable phlebitis events, expressed as episodes per 1,000 IV catheter days. Scores of 3–5 are particularly important for quality review. Consistently low scores following a robust assessment programme indicate IV therapy standards are being met.
