Organisation Accountability
Combines PHSO annual complaint statistics (volume, remedy compliance) with published decisions portal data (uphold rate). Sorted by upheld rate for organisations with 5+ investigated decisions. Benchmark: 73% average upheld rate among fully investigated decisions. This differs from the headline 18% figure, which includes all 3,340 published decisions — most of which were closed before full investigation (upheld/not upheld only applies to fully investigated cases). Sparklines show complaint volumes received 2019–20 → 2024–25.
Received = complaints received in most recent year (PHSO annual data). Remedy compliance = % of PHSO-recommended remedies complied with across all available years. — = no data in that dataset for this organisation.
