Values and averages are published by CMS (July 2026 release); "—" means CMS publishes no average for that measure. Where CMS assigns a risk-adjusted category ("Better than", "As" or "Worse than Expected"), that category is shown — we never rank those measures ourselves. For the other measures, "Better than X%" is computed by DialysisCompare: the share of Connecticut facilities with at least 25 patients in the measure that this center does better than; centers with fewer patients are not ranked. One measure never tells the whole story — how every figure is sourced and computed.
Questions to ask this center
Prompts for a conversation with the center or your kidney care team, generated only where CMS rates a measure "Worse than Expected", where this center is in the bottom quarter of Connecticut facilities on a measure with at least 25 patients, or where it carries a Medicare payment reduction. They are not medical advice and not a verdict on the center.
- Hemodialysis adequacy (Kt/V ≥ 1.2): CMS reports 57% here (40 patients), vs 97% across Connecticut — better than only 0% of Connecticut facilities with at least 25 patients. You could ask how the center checks that each treatment removes enough waste.
- High blood calcium: CMS reports 31% here (40 patients), vs 1% across Connecticut — better than only 0% of Connecticut facilities with at least 25 patients. You could ask how often the center checks calcium levels and how results are followed up.
