Trusts considering an LP at CRP > 10mg/L carry out a significantly higher number of LPs compared with trusts that do not specifically mention this cut-off (median 1.07%, IQR 0.65 – 2.3%, of live births v 0.85%, IQR 0.34 – 1.31%, p=0.042), without a corresponding significant increase in meningitis cases (0.27/1,000 live births, IQR 0.00 – 0.87, v 0.20/1,000, IQR 0.04 – 0.64, p=0.54), as shown in Fig. 2. Here, CRP is linked to infectious meningitis.
