Frailty risk is only half the story; the other half is whether the local acute system has any slack to absorb it. This map joins district frailty to four NHS open data sources on system pressure, and offers a second lens that recolours the map by the hospital trust actually serving each area.
A high-frailty district served by a resilient hospital is a different commissioning problem from an identical district served by a trust already in corridor care. Demand-side intelligence (who is getting frail) is only actionable alongside supply-side intelligence (whether the system can cope). Joining them shows commissioners where unmet need and system strain converge — the points of greatest leverage and greatest danger.
District pressure shades each district by its frailty signal, preserving the granular FEP detail that is Assistiv's distinctive contribution. Hospital systems recolours the map by acute trust catchment, scoring each trust on corridor-care intensity, SHMI mortality banding and 65+ emergency admissions per 1,000 registered 75-and-overs — a demand-adjusted rate that is fair between large and small trusts. Catchments are aligned to predominant acute patient flows; the tool states openly that boundary areas overlap in practice.
Unknown inputs score the moderate midpoint rather than penalising a trust for data it has not yet published — a deliberate choice to avoid manufacturing false reassurance from missing data.
Catchments are approximations. Real patient flows cross every boundary; the hospital lens is a planning aid, not a statement of where any individual will be treated.
Mixed vintages. Corridor care, SHMI and admissions publish monthly or annually while FEP updates daily, so the composite blends data of different ages.
Corridor care is experimental. The corridor-care definition was introduced in March 2026 and remains an experimental statistic; early data should be read as indicative.
