Learn how home health RNs conduct comprehensive assessments and functional testing during the Start of Care (SOC). Discover why these steps matter for compliance, safety, and patient outcomes.
Introduction: Why Assessment Is Everything
In home health, the Comprehensive Assessment is more than a form—it’s the blueprint of care. It tells the agency, the practitioner, and the payer (hello, Medicare) exactly why skilled services are needed. Alongside functional testing, it also captures the patient’s abilities, limitations, and safety risks. Done right, this assessment not only checks compliance boxes—it helps patients thrive at home.
What Is a Comprehensive Assessment?
The Comprehensive Assessment is a full evaluation performed at the Start of Care (SOC), recertification, resumption of care, and discharge. For RNs, the SOC is the big one. It includes:
- OASIS data set (required for Medicare/Medicaid patients).
- Medication reconciliation (see my post on Medication Reconciliation That Sticks).
- Review of systems (head-to-toe health status).
- Safety/environmental assessment (see my post on Arrival, Safety, Identity & Consent).
- Caregiver support assessment (who helps, how often, and with what).
This creates the foundation for the plan of care and documents the skilled need that justifies home health services.
Functional Testing: Measuring What Matters
Functional testing tells the story of how well a patient can manage daily life. It helps determine goals, therapy needs, and progress over time. Common functional assessments include:
- Timed Up and Go (TUG): Measures mobility and fall risk.
- ADLs (Activities of Daily Living): Bathing, dressing, toileting, eating.
- IADLs (Instrumental ADLs): Cooking, shopping, managing finances, using transportation.
- Balance testing (like Berg Balance Scale).
- Strength and endurance measures (like gait speed or sit-to-stand tests).

Why These Assessments Matter
- For Patients: Identifies risks (like fall hazards) and strengths (like independence with ADLs).
- For Families: Provides a clear picture of support needs and safety concerns.
- For Agencies: Supports Medicare compliance and billing accuracy.
- For Practitioners: Creates measurable goals to guide ongoing care.
In short: assessment + functional testing = the roadmap for safe, effective care.
Common Pitfalls (and How to Avoid Them)
- Rushing the assessment → leads to missed details and rework later.
- Not including caregiver input → families often know what happens between visits.
- Forgetting to tie functional testing to skilled need → can lead to denials.
- Poor documentation of education → always note teaching and patient/caregiver understanding.

Final Thoughts: The RN as Architect of Care
The comprehensive assessment and functional testing aren’t just paperwork—they’re the architecture of care. As the RN, you’re designing a plan that’s safe, patient-centered, and Medicare-compliant. Done well, it guides every visit that follows, keeps patients out of the hospital, and builds trust with families.
