    "description": "Most Americans significantly underestimate their lifetime probability of nursing home admission. Industry and academic surveys consistently find that people guess the probability at roughly 20-30%. The 1991 NEJM Kemper & Murtaugh figure of 43% was the long-standing benchmark; the 2017 RAND/PNAS study using more recent HRS data revised it upward to 56%. The perception gap is compounded by a common belief that Medicare covers long-term nursing home stays, which it does not beyond short skilled-nursing periods.\n",

    "assumptions": "Hurd, Michaud & Rohwedder (2017, PNAS) simulate lifetime nursing home use for a representative HRS sample aged 50-55, projecting outcomes to death. The result is that 56% of persons aged 57-61 will spend at least one night in a nursing home during their lifetimes. This is conditioned on having reached roughly age 57-61 (i.e., surviving to middle age). To convert to an unconditional US-adult lifetime probability, we apply the survival probability to the midpoint of the study cohort (age ~59): approximately 93% of US adults survive to age 59 (CDC life tables, both sexes combined). Unconditional estimate: 0.56 × 0.93 × (adjustment for adults who die before 57 having no nursing home exposure) ≈ 0.52, discounted further toward 0.46 accounting for survival from age 18. A simpler approach: The 2019 ASPE study found 28% of adults age 65+ receive ≥90 days of nursing home care. Adding shorter stays (which make up the bulk of the 56%) and applying the survival-to-65 rate: 0.56 × (0.82) ≈ 0.46. This is used as the normalized value. The true unconditional figure for current 18-year-olds is likely in the 0.40-0.52 range; 0.46 is a defensible central estimate.\n",

      "calculation_notes": "Hurd, Michaud & Rohwedder (2017) simulate lifetime nursing home admissions for a representative sample of 50-55 year olds from the Health and Retirement Study (HRS), projecting outcomes to death using microsimulation. Key figures: overall lifetime admission 56%; women 64.1%; men 50.6%. Conditional on having a stay, mean duration is 272 nights; the distribution is highly skewed — median is only 10 nights (many short post-surgical/rehabilitation stays) but 10% experience >1,000 nights. Only 31.6% of individuals paid any out-of-pocket costs; the remainder were fully covered by Medicare, Medicaid, or private insurance. Normalized estimate: 0.56 × 0.82 (survival to age 65, as proxy for adult lifetime) ≈ 0.46. This undershoots slightly because the HRS cohort is already 57-61 at baseline; true unconditional risk from age 18 is somewhat lower, making 0.46 a reasonable central estimate.\n",

  "caveats": "The 56% figure (Hurd et al. 2017) measures the probability of spending at least one night in a nursing home — a very broad threshold that includes short rehabilitation stays after surgery or a hospital episode. The 28% figure from ASPE (2019) measures receiving 90 or more days of nursing home care, which is a more conventional definition of \"long-term\" nursing home use. The normalized 0.46 estimate is based on the broader Hurd 56% figure adjusted for unconditional lifetime probability from age 18. Figures do not cover assisted living or home health care, which are the more common settings for LTSS. Medicare covers skilled nursing facility care for up to 100 days following a qualifying hospital stay; beyond that, costs fall on individuals or Medicaid. The 2024 Genworth/CareScout survey put the median annual cost of a private nursing home room at $127,750, making multi-year stays a major financial risk for middle-income households.\n",
