Prevention of Central Line-Related Bloodstream Infections (CRBSI) on NNU Wales Neonatal Audit and Outcomes Day Cardiff, 07/10/2015 Sandar S, Ratcliffe C, Abelian A, Wrexham Maelor Hospital, BCUHB

Timeline Jan 2010 – Jan 2011 prospective Audit showed high rate of CRBSI; Jan 2013 – CRBSI prevention guideline introduced; Jun 2013 – June 2014 – prospective re-Audit; Aug 2014 – Aug 2015 – second prospective re-Audit.

CRBSI Prevention Guideline Based on the 2011 Centers for Disease Control (CDC; USA) recommendations:  Maximal barrier precautions;  Use of Hydrex ® pink (0.5% chlorhexidine in 70% alcohol);  Check and do list for clinicians;  Bundled supplies;  Staff education and nurse empowerment to stop non-urgent insertions if proper procedures weren’t followed.

Objectives Compare CRBSI rates pre- and post- Guideline; Compare CRBSI rates to those reported by CDC; Describe factors leading to CRBSI; Describe CRBSI-related morbidity.

Methods Prospective data collection; Definition of CRBSI: growth of the same organism in blood and tip cultures obtained within 48 hrs of each other (CDC 2011 criteria); Primary outcome measure: number of central line days per one CRBSI; Secondary outcome measure: length of central line stay before removal (days).

Data analysis (long lines only)

Conclusion Clear and sustained improvement in CRBSI rate since the implementation of the prevention measures; No additional costs; Rate of CRBSI comparable to that reported by CDC (4-10 per 1000 central line days).

Recommendations Continue to engage medical and nursing staff in ensuring adherence to the Guideline; Continue ongoing audit of CRBSI; Establish audit of CRBSI in other units across Wales - is there scope for an All- Wales guideline?

Morbidity and Mortality CRBSI-related deaths, n 310 CRBSI –related significant morbidity (recovery >48 hrs), n 311

Case 1 Case 2 29/40 Prolonged TPN LL in situ 15/7 BC + and LL tip + Staph Epidermidis Full recovery in 72 hours 28/40 UAC and UVC inserted day 1 UAC removed day 3 Respiratory distress day 5  UVC removed BC + and line tip + Staph Epidermidis Recovery within 48 hours Cases

Infection no weeker, passed away. Gestation 26 +4, birth weight 930g; UAC in-situ for 21 days removed due to occlusion; New UAC inserted into the same artery immediately; Passed away on day 25: blood cultures (x3) grown Staphylococcus epidermidis; Learning point: do not re-insert umbilical lines.

Infection no 2; full recovery after 7 days Gestation 32, birth weight 1670g; UVC in situ since birth; Became clinically unwell needing CPAP on day 4; CRP went from 2.6 on day 4 to 46 on day 5; Tretated with co-amoxiclav and gentamicin until day 6; Rapid improvement following introduction of teicoplanin on day 7 (when CRP rose to 76); Required increased respiratory support (CPAP) and increased nutritional support at 48 hours; Full recovery of symptoms after 7 days of treatment; Staph epidermis in blood culture and UVC tip cultures.; Learning point: use anti-Staph epi antibiotic early in an unwell baby with a central line in situ.

Infection no 3; full recovery in 48 hrs Gestation 34, birth weight 2055g; Day 5 of life; UVC inserted after multiple attempts to insert a long line; Day 7 of life clinically deteriorated, Staph epi growth in blood culture and from UVC tip; Treated with Teicoplanin with full recovery of symptoms by 48h; Learning point: prolonged procedure increases infection risk.
