Who Am I ?
• I am– A Medical Oncologist (MCCN)– Site specialist and general remit– Awareness of FN issues across Centre/Unit– Awareness of FN issues at National level (as failed CI
for ORANGE Trial!)– Keen interest in reducing unnecessary hospital stays– Enthusiast for AO
• I am NOT:– Sepsis Expert – or reader of ITU weekly chronicle

Aims
• Overview & Background
• General Principles of management
• Risk Stratification
• Low risk strategies
• FN management in the real world
![Page 4: Neutropenic Sepsis Acute General Management and SupportDGH: Case I •Cancer Centre Triage call 16.30 •Advised to attend local A&E 18.30 •Low risk : •CCO informed and advice](https://reader033.fdocuments.in/reader033/viewer/2022052013/6029bbed08f7174c4e29203f/html5/thumbnails/4.jpg)
Why is FN important ?
• Remains a life threatening complication (5% in high risk but 1% in low risk)
• Compromise survival with dose delays, reductions
• FN is not going away– Significant increase in chemo use
– Remains an issue with new therapies
• Well recognised but poorly managed (NCEPOD)
• Increasing burden on DGHs
• Poor patient experience
• Limited high quality research
![Page 5: Neutropenic Sepsis Acute General Management and SupportDGH: Case I •Cancer Centre Triage call 16.30 •Advised to attend local A&E 18.30 •Low risk : •CCO informed and advice](https://reader033.fdocuments.in/reader033/viewer/2022052013/6029bbed08f7174c4e29203f/html5/thumbnails/5.jpg)
How Big a Problem?
• We don’t know• Limited data on incidence, mortality, LOS...• No recognised code: current hospital coding uses:
– A41.9 (sepsis)– D70.X (neutropenia)– Y43.3 (‘chemo-related)
• Predominantly Breast/Lung Cancer• Cancer Centre
– CCO audits : 100 over 6mths (4/week)– SWLCN 71 episodes over 3months (6/week)
• DGH data– SH&K FN and AOT Audit: 1-2 per week
![Page 6: Neutropenic Sepsis Acute General Management and SupportDGH: Case I •Cancer Centre Triage call 16.30 •Advised to attend local A&E 18.30 •Low risk : •CCO informed and advice](https://reader033.fdocuments.in/reader033/viewer/2022052013/6029bbed08f7174c4e29203f/html5/thumbnails/6.jpg)
Prevention strategies
• Prophylactic Antibiotics
• CSFs: FN risk > 20% in curative cancer where no other regimen available
• Decision to Treat– PT SELECTION
– CHEMO Protocol
NCEPOD:
86% palliative intent
‘20% of cases, decision to treat was assessed as inappropriate’

Background
• Fever ≥ 380C on 2 occasions AND neutrophilcount ≤ 0.5 x 109/l
• Duration in solid tumour 3-5days ( Acute Leukaemia:23-27days)
• 50% of febrile pts have clinically documented infection
![Page 8: Neutropenic Sepsis Acute General Management and SupportDGH: Case I •Cancer Centre Triage call 16.30 •Advised to attend local A&E 18.30 •Low risk : •CCO informed and advice](https://reader033.fdocuments.in/reader033/viewer/2022052013/6029bbed08f7174c4e29203f/html5/thumbnails/8.jpg)
Presentation
• Awareness
• Fever, non-specific symptoms
• Usually 7-14days post chemotherapy
• Mucosal damage, catheter-related
• May present with no fever, confusion, (steroids, overwhelming infection)

Low Risk Strategies
Inpatient Care• Low dose Monotherapy• ‘Step down’ policies
– POCs
• Inpatient oral combination• Inpatient oral monotherapy
– EORTC 46001 moxifloxacin vs co-amoxyclav/Cipro
• Early discharge policiesOutpatient Care• Outpatient parenteral antibiotics• Outpatient oral antibiotics

Inpatient Oral Antibiotics
• 2 International randomised trials*
• Systematic review & metaanalysis (15)
• Low risk inpatients
• Oral co-amoxyclav & ciprofloxacin vs iv standard
• RR, duration of antibiotics and smc rate: equivalence

UK Audit of managementInnes et al BJC 2005
• 128 Clinicians from 50 Cancer Departments
• 22% use oral antibiotics from outset
• 38% stratify but variable risk indices
• 51 % of stratifiers use oral antibiotics vs 4% not (p< 0.0001)
• Phillips et al 2007: UK Childrens Cancer Study Group survey: Wide variation in all aspects of care

CCO Experience
• Single Centre oral versus iv trial & sequential audits (1997-)
• Findings (Innes et al 2003, 2008)– Routine clerking proforma incorporating MASCC index
– Majority are low risk patients
– Oral antibiotics safe and effective
– Median duration of stay: Reduced to 2days
– 50% cost savings and reduced nursing time (GRASP)

The ORANGE Trial
A Randomised phase III trial evaluating early hospital discharge in low risk patients receiving oral antibiotics
Trial Closed Early April 2007:27 patients registeredNo SMCs, No readmissions, LOS 2 days.
34 sites declined entry due to:Complex admission pathwaysMajority of patients not managed within treating centreInability to carry out MASCCTrial management & out of hours careConflicting local antibiotic policyConflict with C Difficile policies

Patient PathwaysAll familiar with Standards
– Patient information– 24 hour specialist triage– Speedy access to specialist care and antibiotics– FN guidelines
– Compliant with standards BUT does it work in practice?
– NCEPOD• 94% have policies in place BUT• ? Suboptimal patient information• Dislocation of care with many admitted to units under
general physicians

St Helens & Knowsley NHS TrustAudit (2007)
• Snap shot analysis revealed:
– Lack of awareness of care pathways in A&E
– Conflicting triage pathways (FN & Manchester)
– Negative impact of 4hr targets
– No iv antibiotics in A&E
– Delays in first antibiotics up to 12hours
– Delayed antibiotics on Day unit and inpatient Facility due to lack of medical staff and beds.

New pathway • Talk to A&E! (joint working Group)
• Patient alert card introduced• Electronic alert system• Integrated Triage with A&E
pathway• Antibiotics before pt transferred• AO review 24hrs• Re audit 2008:
– 22 patients (9 months) – All received abs < 4hrs– Improved awareness and
communication– High risk LOS 6 days, low risk LOS
4 days

‘Winning principles’www.improvement.nhs.uk/winning_principles
Transforming Inpatient Cancer Care
• I: Assess before admission: – Improve triage, A&E risk stratification, alerts
• II: Patients should be on a defined inpatient pathway– A&E, AOT review
• III : Daily review– AOT
• IV : Pt information and self management
![Page 31: Neutropenic Sepsis Acute General Management and SupportDGH: Case I •Cancer Centre Triage call 16.30 •Advised to attend local A&E 18.30 •Low risk : •CCO informed and advice](https://reader033.fdocuments.in/reader033/viewer/2022052013/6029bbed08f7174c4e29203f/html5/thumbnails/31.jpg)
Summary
• FN is a potentially lethal complication BUT in a minority• We need to improve pathways for all FN patients• Progress requires integrated approach with triage,
Centres, A&E and AOT• Need to improve Pt selection and introduce risk
stratification• AO offers significant opportunities to reduce mortality,
improve pt experience and reduce hospitalisation• AO offers new opportunities to develop real world R&D
and link with NCRN• Forthcoming NICE guidance
