Informed Consent in Vascular Access: Why It Matters More Than a Signature

When placing a PICC line, midline catheter, or any vascular access device, informed consent is not just paperwork—it is a critical patient-safety process grounded in ethics, education, and trust.

At Optimus Vascular, we follow the Infusion Nurses Society (INS) Standards of Practice, which define informed consent as an ongoing, collaborative communication process, not a one-time form.

This article explains:

• What informed consent really means in vascular access

• Common real-life scenarios clinicians face

• How proper consent protects patients, nurses, and facilities

• How Optimus Vascular supports compliant, patient-centered consent

What Is Informed Consent in Vascular Access?

According to INS Standards, informed consent involves ensuring that the patient (or surrogate decision-maker):

• Understands why the device is recommended

• Knows the benefits, risks, and alternatives

• Has the opportunity to ask questions

• Makes a voluntary, informed decision without pressure

Consent may be:

• Written, verbal, or documented per facility policy

• Obtained directly from the patient or a legally authorized surrogate

• Reconfirmed for ongoing or repeat therapies

📌 Key point: Consent is a process, not just a signature.

Real-Life Scenario #1: “The Patient Who Didn’t Know Why a PICC Was Ordered”

A vascular nurse arrives to place a PICC line.

The patient says:

“They told me you were coming, but I don’t know why I need this.”

🚩 Red flag.

Even with a valid provider order, INS Standards require that:

• The patient understands the purpose of the device

• Risks and alternatives are explained in plain language

Best Practice

The clinician pauses, explains:

• Expected duration of therapy

• Why peripheral IVs may no longer be appropriate

• Risks such as infection or thrombosis

• Alternatives like a midline or ultrasound-guided peripheral IV

Only after the patient understands and agrees does the procedure proceed.

Outcome: Patient feels respected, informed, and safe.

Real-Life Scenario #2: Language Barriers and Consent

A patient nods “yes” to every question but speaks limited English.

INS Standards are clear:

• Interpreter services must be used when language barriers exist

• Family members should not replace professional interpreters unless policy allows

Best Practice

• A certified interpreter is used

• Consent is explained using culturally appropriate language

• Understanding is confirmed before proceeding

Outcome: Ethical care, reduced legal risk, improved patient trust.

Real-Life Scenario #3: Surrogate Decision-Makers

A patient with altered mental status requires urgent vascular access.

INS guidance states:

• Capacity must be assessed

• If lacking, consent must come from a legal surrogate

• Emergencies may allow exceptions, but documentation is critical

Best Practice

• Identify the surrogate decision-maker

• Document the discussion, rationale, and consent method

• Reconfirm consent if therapy continues

Outcome: Regulatory compliance and defensible documentation.

Why Informed Consent Protects Everyone

Proper informed consent:

• 🛡️ Protects patients from unwanted or misunderstood procedures

• 🛡️ Protects nurses and clinicians from legal exposure

• 🛡️ Protects facilities during audits, surveys, and litigation

It also builds confidence, transparency, and trust—especially in mobile and consult-based vascular access services.
