      "q": "What happened to nursing-home quality in Q1 2026?",
      "a": "Across 5,148 skilled nursing facilities, the composite quality score we track fell by an average of 0.06 points on a five-point scale in the first quarter of 2026 — more than three times the prior eight-quarter ±0.02 drift band. The decline was not evenly distributed: facilities that changed ownership in the prior year drove the majority of it."
    },
    {
      "q": "Why did facilities that changed ownership decline more?",
      "a": "The 721 facilities that changed hands in the prior year declined by 0.19 points, against 0.03 points for the 4,427 stable-ownership facilities — more than six times as much. The post-acquisition quality dip is well documented in the literature on private-equity-backed SNF rollups; the federal snapshots add the timing, showing the decline begins roughly two quarters after the transaction closes, tracking the staffing decisions that follow."
    },
    {
      "q": "Is this study claiming ownership change causes quality decline?",
      "a": "No. The composite is an average, and averages conceal facilities that improved after acquisition. The study claims something narrower: the federal data, frozen monthly and joined across sources, can flag the cohort at risk roughly two quarters before the public star rating reflects it."
    },
    {
      "q": "How is an ownership change identified?",
      "a": "From PECOS enrollment deltas cross-checked against CHOW (change-of-ownership) filings. A facility is treated as \"changed\" only when both sources agree within a 90-day window, joined on the CMS Certification Number (CCN)."
    },
    {
      "q": "Can I reproduce these figures?",
      "a": "Yes. Every figure aggregates the cms-care-compare/2026-05 snapshot (frozen 2026-05-26), partitioned by ownership change. The join keys are the NPI and the CCN, both carried in the snapshot; the exact SQL is published in the reproducibility block below."
