Figuring out when a home nurse is necessary is one of the toughest decisions family caregivers face. This guide gives clear clinical and functional triggers for hiring a home nurse, explains what licensed nurses do that personal support workers cannot, and provides step-by-step advice for vetting providers and preparing the home. You will also get practical guidance on costs and funding options, including how Passport funding can help eligible families in Ontario.
1. Clinical and functional signs that indicate you need a home nurse now
Immediate indicator: when clinical needs exceed basic hands-on help, you need a home nurse now. This is not about convenience; it is about preventing complications that lead to emergency visits or readmission. Focus on objective, changeable problems that require assessment, clinical judgment, or technical procedures.
Acute medical transitions and instability
Watch for new or changing acuity: recent hospital discharge with a new IV antibiotic, new oxygen requirement, post-operative bleeding or new cardiac symptoms, recurrent ED visits, or unresolved abnormal vital signs. These require nursing assessment, monitoring, and rapid communication with prescribers.
Wounds, lines, and medical devices
Device and wound complexity: complex wound management (multiple-layer dressings, negative pressure wound therapy), central or peripheral lines, urine diversion devices, or new ostomies. These tasks need sterile technique, ongoing assessment, and documentation that lay caregivers or PSWs are not trained to provide safely.
Medication and therapy complexity
High-risk medications and titration: insulin adjustments, injectable biologics, home IV therapy, or anticoagulation requiring coordinated monitoring. If there are more than five daily medications with interactions or frequent dose changes, a nurse is needed to reconcile, educate, and reduce medication errors.
Functional danger signs: repeated falls, unsafe transfers, new incontinence with skin breakdown, rapid decline in mobility, or caregiver exhaustion preventing safe care. A nurse assesses for equipment needs, documents falls risk, and recommends immediate interventions such as a Hoyer lift or change in care plan.
Trade-off to consider: hiring an RN for short, intensive visits to stabilise clinical issues and teach family caregivers often costs less than prolonged daily RN care. In practice, front-loading nursing visits for the first 72 hours after discharge or a change in condition prevents escalation and lets lower-cost PSWs manage routine ADLs once stable.
Concrete Example: An 82-year-old returning from hospital after a hip repair has increasing wound drainage and needs new oral anticoagulation. A home nurse provides wound assessment and dressing changes, rechecks bleeding parameters with the surgeon, and reconciles medications with the pharmacy. After 5 days of clinical stability and clear teaching, care steps down to a PSW for bathing and meal support.
When in doubt, prioritise a nursing assessment — early nursing intervention prevents complications and clarifies whether ongoing skilled care is required.
If you see any of these triggers, arrange a nursing assessment and have the discharge summary and medication list ready. For Ontario-specific pathways see Home and Community Care Services or contact a local provider for rapid visit options.

Frequently Asked Questions
Straight answer first: the single most useful step is a nursing assessment — not guessing whether a PSW can handle it. A licensed home nurse determines clinical need, documents risk, and gives a clear plan you can act on.
Who do I call first: a nurse or a personal support worker?
Start with the highest clinical skill required. If the issue includes new devices, changing vitals, complex medication routines, or wound care, call for a home nurse. If the need is strictly bathing, feeding, or transport after clinical stability is confirmed, a PSW is usually appropriate.
How quickly should a nurse visit after hospital discharge?
Aim for assessment within 24 to 48 hours when there are new clinical orders. Faster is better for IVs, new anticoagulation, or any sign of instability. For routine post-op follow-up without complications, 72 hours is acceptable but slower responses increase risk of missed deterioration. For Ontario pathways see Home and Community Care Services.
Can a nurse change medications or give injections at home?
Nurses act on clinical orders, standing orders, or delegated authority — they do not change prescriptions on their own. Expect nurses to reconcile medications, suggest adjustments to prescribers, and execute orders such as insulin injections or subcutaneous opioids. Practical trade-off: getting a clear written order up front avoids delays and informal workarounds that compromise safety.
How do I verify a nurse and what are practical red flags?
Verification is straightforward and non-negotiable. Ask for a licence number, current liability coverage, and recent immunization status. Confirm identity with a photo ID at first visit and require a written care plan within 48 hours.
- Red flag: provider cannot show licence verification or avoids giving a written care plan
- Red flag: no documented escalation protocol for changes in condition
- Check: whether the nurse is an employee (more reliable backup) or an independent contractor (may offer flexibility but riskier continuity)
Concrete example: A 67-year-old discharged on a 10-day home antibiotic via a PICC received daily RN visits for infusion checks and dressing changes. The nurse documented progress and taught the spouse to spot signs of line infection; after seven days the clinical risk fell and care transitioned to twice-weekly PSW visits for ADLs, reducing cost while preserving safety.
Practical next steps you can do right now: Assemble the discharge summary and current medication list, request a nursing assessment within 48 hours, and insist on a short trial period with a documented care plan and escalation phone number. These three actions convert uncertainty into a safe, testable plan.
