Introduction

South East Acute Hospitals Surgical Prophylaxis Guidelines

Document Reference Number: ASG003 (Full document available on HCI Knowledge Portal)

Revision No : 7

Document Developed/Revised By : SE Acute Hospitals Antimicrobial Stewardship Group (ASG)

Approval Date: March 2024

Next Revision Date: March 2027

Introduction

Surgical site infections represent one of the most common hospital acquired infections. In a May 2017 prevalence survey, surgical site infections constituted 18.1% of all healthcare acquired infection with a prevalence of 1.2% of inpatients. 1

Antibiotic prophylaxis in surgery refers to the planned administration of antibiotics to a patient, who does not have confirmed or suspected infection, for the purpose of reducing the risk that the patient develops infection at the surgical site post-operatively. 2 In order to achieve this, appropriate antibiotics must be given at the correct time and for the appropriate duration.

Increasing the recommended duration of antimicrobial prophylaxis does not lead to an additional reduction in surgical site infection but it is associated with higher odds of acute kidney injury and C. difficile infection. 3 Furthermore, inappropriate use of antibiotics increases both the cost and the selective pressure that favours the emergence of resistant bacteria.

This guideline is adapted from Scottish Intercollegiate Guidelines Network (SIGN) Antibiotic Prophylaxis in Surgery 4 and the joint position statement on surgical antibiotic prophylaxis duration 2021 by HSE Antimicrobial Resistance and Infection Control Team (AMRIC), the HSE Antimicrobial Stewardship Advisory Group & the National Clinical Programme for Surgery (NCPS). 2

This guidance is based on the best available evidence but its application must be modified by professional judgment. The final risk assessment for administration of antibiotic prophylaxis must be undertaken by the patients’ doctor.

Principles of Surgical Antibiotic Prophylaxis


Download / Print Section as PDF

Indication for Prophylaxis

Indication for prophylaxis 5

Do not use antibiotic prophylaxis routinely for clean surgery that does not involve a prosthesis.

Give antibiotic prophylaxis to patients before:

  • Clean surgery involving the placement of a prosthesis or implant
  • Clean-contaminated
  • Contaminated
  • Dirty of infected surgical procedures (antibiotic treatment course in addition to prophylaxis)

Class

Definition

Clean

An incision in which no inflammation is encountered in a surgical procedure, without a break in sterile technique, and during which the respiratory, alimentary or genitourinary tracts are not entered.

Clean-contaminated

An incision through which the respiratory, alimentary, or genitourinary tract is entered under controlled conditions but with no contamination encountered.

Contaminated

An incision undertaken during an operation in which there is a major break in sterile technique or gross spillage from the gastrointestinal tract, or an incision in which acute, non-purulent inflammation is encountered. Open traumatic wounds that are more than 12 to 24 hours old also fall into this category.

Dirty or infected

An incision undertaken during an operation in which the viscera are perforated or when acute inflammation with pus is encountered (for example, emergency surgery for faecal peritonitis), and for traumatic wounds if treatment is delayed, there is faecal contamination, or devitalised tissue is present

Choice of Prophylactic Agent

Choice of Prophylactic Agent

Choice of antimicrobial agent is governed by the procedure and likely implicated pathogens at that site. Also, history must be carefully reviewed for both drug allergy (see Appendix 3) and colonisation with MRSA or multi-drug resistant organisms (MDRO).

  • A glycopeptide (e.g. Vancomycin) should be considered for antibiotic prophylaxis in patients undergoing high risk surgery who are colonised with MRSA.
  • For patients colonised with MDRO or CPE, consult local microbiologist for advice on prophylaxis.

How to Document Surgical Prophylaxis

How to Document Surgical Prophylaxis

Prescribe in the patients’ medication chart in the Surgical Antimicrobial Prophylaxis section or “ONCE ONLY PRESCRIPTIONS” section. The antibiotic used, dose and time of administration may also be recorded on the anaesthetic record sheet.


Download / Print Section as PDF

Timing of Prophylaxis

Timing of Prophylaxis

  • The antimicrobial agent should be administered within 60 minutes before surgical incision. 2,4,6
  • Some agents such as ciprofloxacin and vancomycin require longer administration time and should begin within 120 minutes before surgical incision. 6
  • The aim of prophylaxis is to have maximum tissue antibiotic levels at the time of first incision. A single preoperative dose of antibiotic is as effective for majority of procedures. 2,5,6
  • Additional intra-operative dose may be required for:
    • a procedure longer than 4 hours or
    • Intra-operative major blood loss > 1.5 litres (Re-dose following fluid replacement).
  • Patients who have suspected or documented infection at the time of surgery or within 48 hours post-operatively requires treatment course and not prophylaxis.

*HSE Antimicrobial Resistance and Infection Control Team (AMRIC), the HSE Antimicrobial Stewardship Advisory Group & the National Clinical Programme for Surgery (NCPS) . A joint position statement on surgical antibiotic prophylaxis duration 2021

  • Antibiotic prophylaxis should not be continued beyond the time frames identified above on the basis that drains remain in-situ.
  • Surgical prophylaxis should be distinguished from pre-emptive use of antibiotics to treat early infection e.g. perforated appendix. If infection is suspected or confirmed, the model of antibiotic prophylaxis is no longer applicable.
  • An agent appropriate for surgical prophylaxis may not be optimal therapy for an established infection. Therefore, continuation of an agent as treatment may represent sub-optimal therapy. Treatment agent & duration should be as per antimicrobial prescribing guidelines or infection specialist advice.

Appendix 1: South East Regional Orthopaedic Service Antibiotic Prophylaxis For Open Fractures

Appendix 1: South East Regional Orthopaedic Service Antibiotic Prophylaxis For Open Fractures

PHASE 1 : Within 1 hour of injury and continue until wound excision

Antibiotic Regimen should be administered as soon as possible after the injury:

  • Cefuroxime 1.5 g IV TDS plus Metronidazole 500 mg IV TDS until time of first debridement.
  • In case of IgE-mediated /severe penicillin allergy/anaphylaxis: Use Clindamycin 600mg-1.2g QDS IV plus Gentamicin 3mg/kg once daily IV. Patients with non-severe penicillin allergy (mild / rash only and no history of severe reaction / anaphylaxis / angioedema), a cephalosporin such as Cefuroxime is considered safe and is the agent of choice.
  • In the case of open fractures of the distal phalanx of the finger use Cefuroxime 1.5g TDS IV only – (in case of severe penicillin allergy/anaphylaxis use Clindamycin 600mg-1.2g QDS IV).
  • If history or high risk of MRSA colonisation / infection add Vancomycin 15mg/kg (max 2g) to the antibiotic regimens.
  • In the case of heavily contaminated wounds, e.g. farmyard injuries or injuries with vascular insufficiency or Gustilo Grade III fractures, add Gentamicin 3 mg/kg IV once daily to antibiotic regimen on initial presentation.At the time of first debridement and stabilisation, ensure prophylaxis of Cefuroxime 1.5 g IV and Metronidazole 500 mg IV is given; in addition give Gentamicin 3 mg/kg IV stat pre-operatively (unless Gentamicin has been given in the past 16 hours).
  • Antibiotics after wound excision should continue for 24 hours .

PHASE 2:

  • At the time of definitive skeletal stabilisation and definitive soft tissue coverage the patient should receive a single intravenous dose at induction of Vancomycin 15mg/kg (max 2g) (if it has been more than 12 hour since the last dose) plus Gentamicin 3 mg/ kg (if it has been more than 16 hours since the last dose).

Appendix 2: Post-Splenectomy Prophylaxis in Adults

Appendix 2: Post-Splenectomy Prophylaxis in Adults

Note: These guidelines are intended for use in adult patients only. For immunisation schedule for children with splenectomy or hyposplenism seek expert advice and refer to National Immunisation Guidelines.

  • Individuals with an absent or dysfunctional spleen are at increased of fulminant infection especially from encapsulated bacteria such as Streptococcus pneumoniae, Neisseria meningitidis and Haemophilus influenzae.
  • Patients should be encouraged to wear an alert bracelet or equivalent and carry a card with information about their condition. Patients should be educated about the risks of animal exposure including bites and potential risks of tick and mosquito-borne diseases when travelling.
  • It is essential to educate patients regarding the risk of infection, the importance of vaccines and antimicrobial prophylaxis, and prompt recognition and treatment of any infections that develop.

Vaccination

  • For those requiring splenectomy, vaccination should be completed at least 2 weeks and preferably 4 weeks or more before surgery.
  • In the case of emergency splenectomy, or if immunisation was not completed pre-operatively, vaccination can be commenced 2 weeks post operatively.
  • Advise general practitioner in discharge letter of requirement for these vaccines.
  • In immunocompromised patients, seek expert advice regarding timing of vaccination.

Additional vaccines for those with asplenia or hyposplenia

Neisseria meningitidis

MenACWY

2 doses 2 months apart; booster every 5 years

MenB

If unvaccinated, 2 doses 1 month apart

Streptococcus* pneumoniae

PCV13*

1 dose ≥ 2 months after previous dose.

If unvaccinated, 2 doses 2 months apart

PPV23*

1 - 3 doses

1st dose at least 2 months after PCV13

2nd dose 5 years later

Final dose at >65 years

Haemophilus influenzae type b

Hib

1 dose ≥ 2 months after previous dose.

Influenza

Inactivated influenza

Annually

Adapted from National Immunisation Guidelines. Chapter 3 immunisation of Immunocompromised

* Please refer to National Immunisation Guidelines Chapter 16 Pneumococcal Infection . PCV13 should be given first, followed by PPV23 at least 2 months later.

Antimicrobial Prophylaxis

The increased risk of infection is life-long but is highest early after splenectomy. The risk is greatest in children up to the age of 16 years and in adults over 50 years.

Lifelong prophylactic antibiotics should be offered to patients considered at continued high risk of pneumococcal infection:

  • age less than 16 years or greater than 50 years
  • inadequate serological response to pneumococcal vaccination
  • a history of previous invasive pneumococcal disease
  • splenectomy for underlying haematological malignancy particularly in the context of on-going immunosuppression

Antibiotic prophylaxis is recommended for a minimum of 1 to 2 years in low risk patients but these patients should be counselled regarding the risks and benefits of lifelong antibiotics and may choose to continue or discontinue prophylaxis.

Oral penicillin is the drug of choice

  • Penicllin V (Calvepen TM ) 666mg po q12h OR amoxicillin 250-500mg q12h po
  • In patients with confirmed penicillin allergy, clarithromycin 250 mg bd po is an alternative option.

Consider interactions with other drugs and consult with hospital pharmacist if necessary.

Note: Patients developing symptoms and/or signs of infection, despite the above measures, must be given systemic antibiotics and admitted urgently to hospital.

Appendix 3: Penicillin Allergy

Appendix 3: Penicillin Allergy

** It is important to document exactly what symptoms occurred before deciding if a patient is truly penicillin allergic. Check with Patient / Relatives / GP / Community Pharmacist to clarify the nature of allergic reaction.**

  • Many patients are misdiagnosed as being penicillin allergic.
  • An incorrect diagnosis of penicillin allergy leads to unnecessary avoidance of this relatively non-toxic class of drugs, exposes the patient to potentially more toxic drugs, increases health care costs and contributes to the development of antibiotic resistance.
  • Patients are often labelled as having a hypersensitivity reaction when in fact a patient may be experiencing a side effect of penicillin, such as gastrointestinal upset (e.g. nausea, diarrhea) or headache.
  • Other concomitant medicines can also be responsible for triggering a hypersensitivity reaction. Therefore, it is important to consider the timeframe over which the hypersensitivity reaction has developed relative to the initiation of different medications.
  • Patients who have previously presented with a less severe penicillin allergy (e.g mild-moderate rash not on the EM/SJS/TEN spectrum of rash and not requiring hospitalisation ) may be considered to be prescribed cephalosporins/carbapenems if the benefits outweigh the risks of cross reactivity. This is a clinical risk assessment. The potential for an allergic reaction should be monitored and resuscitation equipment available if required.
  • However, patients who are documented as having experienced a severe reaction (e.g. anaphylaxis) from a penicillin should not be prescribed cephalosporins, carbapenems and other beta-lactam containing antibiotics where acceptable alternatives available. A risk-benefit assessment may be needed in certain circumstances. Discuss individual case with senior clinician and clinical microbiology team if needed.

Appendix 4: Prophylaxis Pre-TRUS Guided Prostate Biopsy

Appendix 4: Prophylaxis Pre-TRUS Guided Prostate Biopsy

Antimicrobial prophylaxis is recommended for ALL patients undergoing TRUS-guided prostate biopsy

The figures below outline the recommended approach.

Patients with a history of colonisation/infection or with risk factors for CRE/CPE (Carbapenem Resistant Enterobacterales/ Carbapenemase Producing Enterobacterales) should be screened in advance with a rectal swab for CRE/CPE carriage and not listed for TRUS-guided prostate biopsy pending CRE/CPE screening results.

Risk factors may include but are not limited to:

  • History of fluoroquinolone use in the previous six months
  • Patient is a healthcare worker
  • Previous sepsis/infection following TRUS-guided prostate biopsy
  • History of antimicrobial resistant Enterobacterales colonisation/infection (e.g., ESBL, fluoroquinolone and/or aminoglycoside resistance)
  • Other risk factors as per local policy

If the results of CRE/CPE screening are positive, it is recommended that the multi-disciplinary team (MDT) discuss the optimal strategy for performing the prostate biopsy safely in this patient.

Thereafter there are two recommended options (2a and 2b in Figure 1):

Oral ciprofloxacin 750mg as a one drug antimicrobial prophylaxis regimen for patients without risk factors for colonisation with resistant Enterobacterales .

Patients with risk factors for antimicrobial resistant Enterobacterales (other than CRE/CPE) should be given a two drug antimicrobial prophylaxis regimen.

A combination of ciprofloxacin and an aminoglycoside is recommended (unless the patient has a history of previous microbiology results indicating resistance to fluoroquinolones and/or aminoglycosides, in which case the prophylaxis choice should be discussed with the local Clinical Microbiologist

Before prescribing antimicrobial prophylaxis, it is important to document if the patient has an antimicrobial allergy and calculate the Creatinine Clearance (CrCl) for adjustment of dosing/therapy in renal impairment.

Please note important safety information, cautions and contraindications if prescribing a quinolone including risk of tendon damage, seizures & prolonged QT interval. Please see European Medicines Agency review for further details
