Patient experience (Friends & Family Test)
Trust-wide (Chelsea And Westminster Hospital NHS Foundation Trust) · Latest month: June 2026· a voluntary, monthly feedback survey — the figure is the share of respondents who rated their experience 'good' or 'very good'. Response rates are often low and respondents are self-selected, not a representative sample, so read this alongside the clinical measures above, not on its own.
2025 · the views of staff who work at this trust — a measure of workforce culture, morale and confidence, not a direct measure of clinical outcomes. There is no official NHS target for these figures, so they are shown as context, never a pass or fail.

The NHS Staff Survey records the views of staff who chose to respond — a measure of workforce culture, morale and staff confidence, not a direct measure of clinical outcomes or safety. Response rates vary between trusts. England only; Scotland, Wales and Northern Ireland run separate staff surveys on a different basis, so these figures are never compared across nations.

Bed occupancy, ambulance handovers & delayed discharges (UEC Daily SitRep)
Trust-wide (Chelsea And Westminster Hospital NHS Foundation Trust) · Snapshot at 8am, 29 March 2026. This is unvalidated management information— NHS England's own label — and can be revised for up to 14 days after first publication. It is collected only during the winter Daily SitRep window, so this is the latest date the collection has published, not necessarily today. It measures operational pressure (how full the hospital is), NOT care quality — high occupancy is normal for NHS hospitals, especially in winter, and is not a safety or performance score. The ambulance-handover figures below cover winter 2025-26 as a period total(not a snapshot): the time from an ambulance arriving to the patient being handed over to A&E staff. The delayed-discharge figures cover the most recent 7 daysof the collection (not a snapshot, and not the whole winter): a patient who "no longer meets the criteria to reside" is medically ready to leave hospital, but how quickly they actually do mostly reflects social-care and community capacity to receive them — NOT the hospital's own clinical quality. A higher handover or delayed-discharge figure means more operational pressure — like the rest of this section, none of it is a measure of care quality, and it carries no colour grading, badge or ranking.
