Home Health Star Rating Improvement Case Study
How we helped a 900-patient home health agency climb from 2.5 to 4.5 quality stars in 12 months—driving a 35% increase in referral volume from hospital and SNF partners.

The Challenge
A 900-patient home health agency in a competitive urban market had watched their referral relationships erode as their Home Health Compare star rating dropped from 3.5 to 2.5 over three years. Hospital discharge planners and SNF social workers had begun diverting referrals to higher-rated competitors—a trend the agency's leadership could see in their admission data but had struggled to reverse.
The agency provided genuinely good care. Patient outcomes were strong by internal measures. But their publicly reported star rating told a different story, and the agency couldn't reconcile the gap. A clinical quality consultant had suggested the problem might be documentation-related, but the agency lacked the data infrastructure to test that hypothesis or identify which specific OASIS items were most responsible for their below-average performance.
The financial stakes were significant. The referral decline had reduced admission volume by approximately 140 patients per year—a revenue impact of $2.1 million annually at their average revenue per patient. The HHVBP payment adjustment added another layer of financial pressure, with the 2.5 star rating translating directly to a downward payment adjustment.
Our Approach
OASIS Outcome Measure Analysis and Benchmarking
We analyzed the agency's performance on each of the nine quality outcome measures driving their star rating, benchmarked against state and national averages, and identified the four measures with the largest performance gaps. Improvement in bathing, improvement in ambulation, acute care hospitalization rate, and discharge to community were each performing at the 25th percentile or below—the primary drivers of the 2.5 star rating.
OASIS Accuracy Remediation Focused on Quality Measures
Analysis of paired SOC and DC OASIS assessments revealed systematic undercoding at start-of-care—functional status was being documented as better than it actually was, which suppressed apparent improvement at discharge. We implemented inter-rater reliability training focused specifically on the functional OASIS items that drive the quality measures, using video scenarios and monthly accuracy testing to drive consistent improvement in SOC scoring.
Clinical Pathway Development for High-Volume Diagnoses
The agency's top five admission diagnoses accounted for 63% of their patient volume. We developed evidence-based clinical pathways for each diagnosis, specifying the interventions, frequency, and documentation elements most likely to produce measurable functional improvement by discharge. Clinicians following these pathways achieved 34% higher improvement rates on quality measures compared to those following their prior unstructured approach.
HHCAHPS Improvement Program
Patient experience scores were equally below average and accounted for 25% of the star rating. We implemented a structured communication protocol for every visit, proactive care coordination check-ins between visits, and a patient education framework covering medications and self-management. Survey response rate improved from 21% to 44%, and the higher volume of responses reduced statistical volatility while the improved care experience drove higher scores.
