Anaemia | Variation in Hb thresholds for diagnosing anaemia was observed. Lower limits ranged from 105 to 115g/L and upper limits ranged from 115 to 129g/L. Not all Trusts used sex-dependant thresholds | 397–2805 | 20.4–100% | 16.4–98.1 | 0–25 | 11–100% | MSSA: 0–0.7% Anyc: 0–1.1% | 0–11.6% |
Infection | 6 Trusts screened and only decolonised MSSA-positive patients. MSSA-positive rate ranged from 21.9 to 31.2% 10 Trusts decolonised all patients without screening | 457–2786 | 22.6–100% | 0–94.1% | 0–75 | 9–100% | MSSA: 0–0.7% Anyc: 0–2.1% | 0–7.7% |
