   INTRODUCTION
          Antibiotics are essential treatments for serious infections. They are one of the most
   important and valuable discoveries of modern medicine. However administration of antibiotics
   can lead to the selection of antibiotic-resistant organisms. These organisms can give rise to
   healthcare-associated infections which are associated with increased morbidity and mortality.
          Therefore it is important to ensure that antibiotics are prescribed in a way which
   minimizes the risk of healthcare-associated infections. Hospital Antibiotic Guidelines have been
   designed to treat common infections effectively and with the minimum risk of healthcare-
   associated infections. The current antibiotic policy describes the procedures to encourage the use
   of the Antibiotic Guidelines and to ensure that antibiotics are not prescribed in a way which is
   likely to lead to healthcare-associated infections.
          This policy deals with the processes by which recommendations for specific antibiotic
   treatments are made and the procedures to support these recommendations. It does not provide
   specific advice on which antibiotics should be used in specific infections as this is covered in the
   Drug Formulary Antibiotic Guidelines. This policy also does not provide information on which
   antibiotics are regarded as having the highest risk of causing healthcare-associated infections nor
   on which antibiotics can only be used following advice from a microbiologist or infectious
   diseases physician. This is because this will vary between clinical areas depending on recent
   infection surveillance data.

                                                                                   22/02/2017
                                                 Document No :                  Date of Revision:
                                                  SH/AP /M/ 01                     08/02/2017
   Ideally, an antimicrobial agent for surgical prophylaxis should (1) prevent SSI, (2) prevent SSI-
   related morbidity and mortality, (3) reduce the duration and cost of health care (when the costs
   associated with the management of SSI are considered, the cost-effectiveness of prophylaxis
   becomes evident), (4) produce no adverse effects, and (5) have no adverse consequences for the
   microbial flora of the patient or the hospital.53
   To achieve these goals, an antimicrobial agent should be (1) active against the pathogens most
   likely to contaminate the surgical site, (2) given in an appropriate dosage and at a time that
   ensures adequate serum and tissue concentrations during the period of potential contamination,
   (3) safe, and (4) administered for the shortest effective period to minimize adverse effects, the
   development of resistance, and costs
   These Recommendations are provided for adult (age 19 years or older) and pediatric (age 1–
   18years) patients. These guidelines do not specifically address newborn(premature and full-term)
   infants.
   While the guidelines do not address all concerns for patients with renal or hepatic dysfunction,
   antimicrobial prophylaxis often does not need to be modified for these patients when given as a
   single preoperative dose before surgical incision.
   The recommendations herein may not be appropriate for use in all clinical situations. Decisions
   to follow these recommendations must be based on the judgment of the clinician and
   consideration of individual patient circumstances and available resources.
       a. Preoperative-dose timing:
   Successful prophylaxis requires the delivery of the antimicrobial to the operative site before
   contamination occurs. Thus, the antimicrobial agent should be administered at such a time to
   provide serum and tissue concentrations exceeding the minimum inhibitory concentration (MIC)
   for the probable organisms associated with the procedure, at the time of incision, and for the
   duration of the procedure.

                                                                                   22/02/2017

                                                 SH/AP /M/ 01                      08/02/2017
   Overall, administration of the first dose of antimicrobial beginning within 60 minutes before
   surgical incision is recommended.
   Administration of vancomycin and fluoroquinolones should begin within 120 minutes before
   surgical incision because of the prolonged infusion times required for these drugs. Because these
   drugs have long half-lives, this early administration should not compromise serum levels of these
   agents during most surgical procedures.
   Weight-based dosing: The dosing of most antimicrobials in pediatric patients is based on body
   weight, but the dosing of many antimicrobials in adults is not based on body weight, because it is
   safe, effective, and convenient to use standardized doses for most of the adult patient population.
   However, in obese patients, especially those who are morbidly obese, serum and tissue
   concentrations of some drugs may differ from those in normal-weight patients because of
   pharmacokinetic alterations that depend on the lipophilicity of the drug and other factors.
   Obesity has been recognized as a risk factor for SSI; therefore, optimal dosing of antimicrobial
   prophylaxis is needed in these patients.
      c. Redosing.
   Intraoperative redosing is needed to ensure adequate serum and tissue concentrations of the
   antimicrobial if the duration of the procedure exceeds two half-lives of the antimicrobial or there
   is excessive blood loss (i.e., >1500 mL)
                                               Page 4 of 24

                                                                                      22/02/2017
                                                 Document No :                     Date of Revision:
                                                  SH/AP /M/ 01                        08/02/2017
   The redosing interval should be measured from the time of administration of the preoperative
   dose, not from the beginning of the procedure.
   Redosing may also be warranted if there are factors that shorten the half-life of the antimicrobial
   agent (e.g., extensive burns)
   Redosing may not be warranted in patients in whom the half-life of the antimicrobial agent is
   prolonged (e.g., patients with renal insufficiency or renal failure)
      d. Duration.:
   The duration of antimicrobial prophylaxis should be less than 24 hours for most procedures.
   A cardiothoracic procedure for which prophylaxis duration of up to 48 hours has been accepted
   without evidence to support the practice is an area that remains controversial.
   Moreover, prolonged prophylaxis was associated with an increased risk of acquired antimicrobial
   resistance compared with short-term prophylaxis
   There are no data to support the continuation of antimicrobial prophylaxis until all indwelling
   drains and intravascular catheters are removed
      e. Drug administration
   The preferred route of administration varies with the type of procedure, but for a majority of
   procedures, i.v. administration is ideal because it produces rapid, reliable, and predictable serum
   and tissue concentrations.

      g. Drug of choice:
   For most procedures, cefazolin is the drug of choice for prophylaxis because it is the most widely
   studied antimicrobial agent, with proven efficacy. It has a desirable duration of action, spectrum
   of activity against organisms commonly encountered in surgery, reasonable safety, and low cost.
   Routine use of vancomycin prophylaxis is not recommended for any procedure.8 Vancomycin
   may be included in the regimen of choice when a cluster of
   MRSA cases (e.g., mediastinitis after cardiac procedures) or methicillinresistant coagulase-
   negative staphylococci SSIs have been detected at an institution. Vancomycin prophylaxis
   should be considered for patients with known MRSA colonization or at high risk for MRSA
   colonization in the absence of surveillance data (e.g., patients with recent hospitalization,
   nursing-home residents, hemodialysis patients).
   In institutions with SSIs attributable to communityassociated MRSA, antimicrobial agents with
   known in vitro activity against this pathogen may be considered as an alternative to vancomycin.
   The use of vancomycin for MRSA prophylaxis does not supplant the need for routine surgical
   prophylaxis appropriate for the type of procedure.
   When vancomycin is used, it can almost always be used as a single dose due to its long half-life.
   Patients receiving therapeutic antimicrobials for a remote infection before surgery should also be
   given antimicrobial prophylaxis before surgery to ensure adequate serum and tissue levels of
   antimicrobials with activity against likely pathogens for the duration of the operation.
   If the agents used therapeutically are appropriate for surgical prophylaxis, administering an extra
   dose within 60 minutes before surgical incision is sufficient. Otherwise, the antimicrobial
   prophylaxis recommended for the planned procedure should be used.
   For patients with indwelling tubes or drains, consideration may be given to using prophylactic
   agents active against pathogens found in these devices before the procedure, even though
   therapeutic treatment for pathogens in drains is not indicated at other times.
   For patients with chronic renal failure receiving vancomycin, a preoperative dose of cefazolin
   should be considered instead of an extra dose of vancomycin, particularly if the probable

   pathogens associated with the procedure are gram-negative. In most circumstances, elective
   surgery should be postponed when the patient has an infection at a remote site.
      h. Allergy to b-lactam antimicrobials.
   Allergy to b-lactam antimicrobials may be a consideration in the selection of surgical
   prophylaxis. The b-lactam antimicrobials, including cephalosporins, are the mainstay of surgical
   antimicrobial prophylaxis and are also the most commonly implicated drugs when allergic
   reactions occur. Because the predominant organisms in SSIs after clean procedures are gram-
   positive, the inclusion of vancomycin may be appropriate for a patient with a life-threatening
   allergy to b-lactam antimicrobials.
   Although true Type 1 (immunoglobulin E [IgE]-mediated) crossallergic reactions between
   penicillins, cephalosporins, and carbapenems are uncommon, cephalosporins and carbapenems
   should not be used for surgical prophylaxis in patients with documented or presumed
   IgEmediated penicillin allergy.

   Antibiotic timing              Infusion of the first antimicrobial dose should begin within 60 min
                                  before the surgical incision except for vancomycin and quinolones.
                                  When fluroquinolones or vancomycins are indicated, infusions of
                                  the 1st antimicrobial dose should begin within 120 min before the
                                  incision.
   Duration of prophylaxis        Prophylactic antimicrobials should be discontinued within 24 h
                                  after the end of surgery. Patients who have documented infection
                                  at the time of surgery or within 24 hrs of surgery are excluded
                                  from 24 hrs rule. Additionally post CT surgery patient allowed
                                  upto 48 hrs of treatment.
   Screening    for    b-lactam For those operations for which cephalosporins represent the most
   allergy                      appropriate antimicrobials for prophylaxis, the medical history
                                should be adequate to determine whether the patient has a history
                                of allergy or serious adverse antibiotic reaction. Alternative testing
                                strategies (e.g., skin testing) may be useful for patients with
                                reported allergy.
