Health inspection rating: ★★★★☆4/5 · CMS overall rating: 5/5 · how star ratings work →
The health inspection star above is graded on a curve within each state — a set share of each state's facilities gets each star level — so a facility can have few citations and still rate 2–3 stars if others in its state did even better. The overall rating combines that inspection score with staffing and quality measures from resident assessments and claims.
Most serious findings (actual harm or immediate jeopardy)
▲ Immediate jeopardy, pattern · Feb 17, 2023 · F-0801
The facility did not employ enough qualified food and nutrition staff, including a qualified dietician, to properly run its food service.
▲ Immediate jeopardy, pattern · Feb 17, 2023 · F-0801
The facility did not employ enough qualified food and nutrition staff, including a qualified dietician, to properly run its food service.
Why it matters: Without qualified nutrition staff, residents' special diets and nutritional needs may be handled incorrectly, risking weight loss and health decline.
Severity (K): Immediate jeopardy to resident health or safety was cited. The scope was a pattern: more than a limited occurrence, without being widespread. Scope describes the extent of the deficiency, not whether it happened on previous inspections.

Hours are per resident per day for the most recent quarter of payroll data in this CMS release (2026-08-01) — the same quarter for every facility — case-mix adjusted by CMS so facilities caring for sicker residents can be compared fairly (same basis as the CMS staffing star). "Top X%" means better than most facilities: more staffing hours, or lower turnover. Raw (unadjusted) reported hours: total 4.22, RN 0.69, weekend 3.71.Comparing with Medicare Care Compare? Care Compare shows the raw figure (4.22 here, displayed there as hours and minutes), not the adjusted one above. Both are correct; they answer different questions. Staffing rating: 5/5.
Quality measures: assessments & claims
Note: CMS combines facility-reported resident assessments (MDS) with claims-based measures. These are different sources from on-site inspection findings. Read the measures alongside inspection and staffing records; a high QM rating does not establish that a home is safe.
Quality measures rating: 5/5 · long-stay residents: 5/5 · short-stay residents: —/5
Costs & payment
Price evidence · separate from quality
No verified facility-specific private-pay price is available in our data for St John Kronstadt Convalescent Center. CMS inspection and staffing records do not tell us what this home will charge you.
Calculate a stay from a quote you receive
Use a written private-pay quote. This worksheet adds only the amounts you enter; it does not calculate Medicare, Medicaid or insurance benefits.
Formula: (room rate + daily extras) × days + one-time charges. A 30-day scenario is not a calendar-month quote. Refundable deposits, rate changes and charges you omit are not automatically included. Entries are not saved or sent to our server.
Before you compare prices
- Request the room type, effective date and itemized daily rate in writing.
- Ask about therapy, medicines, supplies, care-level charges, deposits, refunds and annual increases.
- Confirm insurance or Medicaid eligibility and bed availability directly; certification alone does not guarantee either.

Questions to ask on your visit
Generated from this facility's actual citation record — bring them to a tour and ask the administrator directly.
- "Do you have a qualified dietician on staff, and how involved are they in each resident's nutrition plan?"
- "Does a pharmacist review every resident's medications and chart monthly, and how are their concerns acted on?"
- "Can you show me how medications are stored and secured on the units, including controlled drugs?"
- "What did your most recent kitchen inspection find, and can I see how food is stored and prepared?"
- "How do you identify and arrange specialized services for residents with mental health conditions or disabilities?"
- "Can you show me an example care plan, and how are families included when it's created and updated?"
- "Can you tell me what this citation involved and what steps you took to bring care back up to standard?"
- "How many aides are on each shift, and how do you make sure every resident gets timely help with bathing, dressing, and meals?"
Also worth asking anywhere
- "What is your current ratio of nursing staff to residents on day, evening, and weekend shifts?"
- "Can I see the plan of correction for the findings in your most recent state inspection?"
- "CMS reports 12% total nursing staff turnover here — who on the care team has been with you longest?"
- "The ownership record on file lists 16 owning or managing parties — who makes the decisions about staffing levels?"
- "Can I visit again unannounced, at a mealtime or on a weekend?"
