The Surveyor's Approach: Evidence-Based Evaluation
CMS surveyors use an evidence-based approach to evaluate facility compliance. They don't just check boxes — they gather evidence through three primary methods: observation, interview, and record review. Each method provides different types of evidence, and surveyors look for consistency across all three.
Observation: Surveyors walk through the facility observing resident conditions, staff interactions, environmental conditions, meal service, medication administration, and activities. What they see often drives their investigation.
Interview: Surveyors interview residents, families, and staff. Resident interviews focus on satisfaction and quality of life. Staff interviews assess knowledge and practices. Family interviews may reveal concerns not apparent through other methods.
Record Review: Medical records, policies, procedures, training documentation, incident reports, quality meeting minutes, and staffing records are all subject to review.
Key Areas of Evaluation
Surveyors evaluate compliance across all requirements of participation, but certain areas receive particular focus:
Quality of Care: Are residents receiving appropriate treatment? Are care plans followed? Are changes in condition identified and addressed promptly?
Resident Rights: Are residents treated with dignity and respect? Do they have freedom of choice? Are grievance procedures in place and effective?
Infection Prevention: Does the facility have an effective infection prevention program? Is hand hygiene practiced? Are outbreaks identified and managed?
Medication Management: Are medications administered correctly? Are unnecessary medications identified and addressed? Is the pharmacy review process effective?
Nutrition and Hydration: Are meals appetizing and nutritious? Do residents receive assistance with eating when needed? Are weight changes addressed?
Environment: Is the facility clean, safe, and homelike? Are temperatures comfortable? Is equipment in good repair?
How Surveyors Select Resident Samples
Understanding the sample selection process helps facilities prepare for what surveyors will focus on. The sample is not random — it's designed to identify potential problems.
Surveyors select residents based on:
- Quality measure data (high-risk scores for falls, pressure ulcers, etc.)
- Facility-reported incidents (falls, injuries, complaints)
- Observations during the initial facility tour
- Specific care needs (residents receiving psychotropic medications, tube feeding, wound care)
- Prior survey history (areas where the facility has been cited before)
For each sampled resident, the surveyor follows a structured investigation process using Critical Element Pathways (CEPs). These pathways guide the surveyor through a series of questions designed to systematically evaluate whether the facility is meeting regulatory requirements for that resident's specific care needs.
