Case 1 28 year old lady previously well, flu symptoms for 4 days Travelled by coach home to family arrived 8pm Family unhappy about her condition called 999 ambulance at 11pm, diagnosed with flu 2 further 999 calls to ambulance service overnight called GP following morning - telephone advice Next day called GP brought into surgery admitted to hospital Cardiac arrest shortly after arrival in hospital

Case 2 43 year old lady previous splenectomy for spherocytosis Went to work at 7am Found unwell in toilet at 10am vomiting + headache declined ambulance Taken home by colleague arrived home at 11am Husband dialled 999 arrived in hospital at 12 mid-day Unrecordable BP, purpura fulminans Survived with antibiotics and supportive care in ITU Bilateral below knee amputations and amputation right hand

Sepsis: Lessons to be learnt Sepsis can affect young previously fit people Can be rapidly progressive Observations often unremarkable until impending death Very difficult to recognise in early stages Non-specific flu-like symptoms GI disturbance Toxic rash (like sunburn rash)

Definition of sepsis

Old definition of sepsis

New definition of sepsis Sepsis is life-threatening organ dysfunction caused by a dysregulated host response to infection Septic shock is a subset of sepsis in which profound circulatory, cellular and metabolic abnormalities are associated with a greater risk of mortality than with sepsis alone

Sepsis mortality (BMJ 2013)

Sepsis 100,000 admissions and 37,000 deaths/year, (10,000 avoidable) More than doubled in last 10 years Overall mortality 35% 5x higher than MI or stroke Every hour of treatment delay increases mortality by 8% Use of sepsis 6 care bundle improves outcome Number needed to treat to save 1 life = 4.6 Poorly recognised and managed in 2013 only 32% of patients treated within 1 hour Could save NHS 196m per year

RCP

University Hospitals of Leicester UHL has made Sepsis the new 5th Critical Safety Action. Dr John Parker Consultant Intensivist will be leading on this. He will be working in partnership with key clinicians from all specialties in UHL to improve sepsis recognition and treatment and to reduce the deaths and disabilities caused by sepsis.

Sepsis: screening and initial management

Sepsis screening The Adult Screening & ImmediateAction Tool must be applied to all adult patients with: a suspected new infection EWS of three (3) or more where staff or relatives have expressed concerns

Antibiotic resistance

Antimicrobial resistance MRSA VRE PRP VISA/GISA VRSA/GRSA MDRTB/XDRTB Falciparum Malaria Multi-resistant Gram -ves Acinetobacter Stenotrophomonas Pseudomonas Salmonella Gonococcus ESBL producers Carbapenamaseresistant organisms (CRO s, CRE s) NDM-1, OXA, KPC

Factors contributing to antibiotic resistance Genetic exchange Overuse of antibiotics Veterinary use Travel Asymptomatic carriage Inadequate infection control Poor Drug pipeline

Factors contributing to antibiotic resistance

Background Antibiotic resistance is a major public health problem. Devt of multidrug-resistant organisms limits choice of therapy Infections with multidrug-resistant bacteria result in higher morbidity and mortality prolonged hospital stay Emergence of C. difficile

Over use of antibiotics Goossens et al Lancet 2005; 365:579.

Antibiotic awareness

The problem

The Solution

RCP guidance All physicians who prescribe antibiotics have a responsibility to prescribe optimally. Clear structures with direct responsibility at Board level for monitoring and agreeing antimicrobial prescribing in hospitals Establishment of a multidisciplinary antimicrobial management team lead doctor, antibiotic pharmacist, infection specialist and senior manager. Agreed antimicrobial formulary should be implemented and performance audited.

RCP guidance

Antimicrobial Stewardship Effective antibiotic prescribing Systems to identify patterns of antibiotic usage. A rolling audit of patient outcome, antimicrobial resistance, and antimicrobial prescribing Antibiotic education strategy that involves all staff involved in antibiotic administration Liaison with appropriate community prescribers to harmonise antibiotic prescribing guidelines Specialist antibiotic ward rounds

Interventions to limit antibiotic prescribing Intervention Effect Collect and feedback data on antibiotic use +/- Educational meetings +/- Antibiotic policies + Information on prescriptions + Antibiotic rounds ++ Restrictive policies ++++ Antibiotic gatekeepers?

Importance of early appropriate therapy Weinsten et al Clin Infect Dis 1997; 24:564 Ibrahim et al Chest 2000; 198:146 Luna et al Chest 1997;111:676

Paradox of antimicrobial therapy Time to initiation of effective antimicrobial therapy is a strong predictor of mortality. Inappropriate or inadequate initial therapy is associated with increased mortality, morbidity, and length of hospital stay. Therapy with broad spectrum antibiotics must be initiated before the causative pathogen is identified.

Summary and conclusions Awareness of sepsis as a major health issue Recognition and immediate management of severe sepsis red flag sepsis Increasing problems of antimicrobial resistance and healthcare associated infections Antibiotic stewardship Antibiotic policies and infection teams CQUINS for sepsis management and antimicrobial use

Outstanding issues for discussion Sepsis difficult to diagnose early Current policy leading to Over-diagnosis of sepsis Escalation of workload Over-use of broad spectrum antibiotics (Meropenem) May exacerbate problems with antimicrobial resistance Tension between antimicrobial stewardship and sepsis management Source control may be neglected
