Timeline March 2016: DH Expert Advisory Group APRHAI recommend to
DH that healthcare-associated GN-BSI should be halved
Sept 2016: Included in CCG Quality Premium 2017/19
Dec 2016: Ruth May, Director of Nursing, NHSI, SRO for IPC
Feb 2016: UK AMR HLSG – consensus across the UK
March 2017: PHE update mandatory database to NHSI requirements
May 2016: Ambition By 2020, we will half HCA-GN-BSI

• “E. coli BSI rates risen due to rising rates resistant organisms” • Increase not just observed in hospital populations • No difference in outcome observed (yet)

Outcome: frequency of UC use and incidence of CAUTIs FINDINGS: Decreased UC rate 27.8% vs 16.9%; relative risk (RR): 0.61;
95% confidence interval (CI): 0.57-0.65 Resulted in reduction in CAUTI risk: 18.3 vs 9.8%; RR: 0.53;
95% CI: 0.30-0.93 Reduction in the CAUTI rate per 1000 patient-days: 5.5 vs 2.8;
incidence ratio (IR): 0.52; 95% CI: 0.28-0.94 Non-significant decrease in the CAUTI rate per 1000 catheter-

Summary
• Gram-negative BSI increasing by ~ 10%/year • High 30 day all cause mortality • Increased MDR infections in hospital onset • Consistent underlying causes of BSI – UTI, CAUTI, SSI • Need to focus on prevention of underlying cause
• improve treatment of UTIs in the community • prevention of nosocomial cases
• High costs to the NHS • Incentives for CCGs • Need to change our behaviour and beliefs
