Data regarding risk factors for surgical procedure and usage of
antibiotics are essential to prevent and treat Surgical Site Infections
(SSI) [1]. Prophylactic use of antibiotics has been found helpful in
reduction of such morbidities. It is a well accepted intervention in
numerous surgical procedures as well. However, there are contra-
verses with the fact that the medical fraternity administers antibiotics
haphazardly. Evidence based guidelines, and boundaries between
prophylactic and therapeutic antibiotic administration are ofen
ignored or disregarded. Literature reveals inappropriate antibiotic
prophylaxis during early 1970s in majority of hospitalized patients
[2,3]. In this context, indication for prophylaxis, and selection and
duration of antibiotics were reported to be irrelevant. However, a
better understanding and selection of antibiotic prophylaxis gradually
developed. Researcher established general principles that addressed
adverse efects of prolonged chemoprophylaxis. Tese principles
lead surgeons with a notion that antibiotics are not a substitute for
suboptimal outcome [4].
Rate of inappropriate antibiotic administration in elective colorectal
surgery was reported to be 73% in nationwide Malaysian survey. Te
survey also identifed area of gap in published national guidelines
for antibiotic administration [5]. Although antibiotic prophylaxis
is considered important in surgical procedures [6], inappropriate
use of antibiotics is however being practiced in 25-50% of general
elective surgeries [7-9]. Meanwhile, beside the fact that appendectomy
does accompany 1-5% of SSI with it [1,10,11], efcacy of antibiotic
prophylaxis in patients undergoing appendectomy has been observed
in several randomized and observational studies [12-17]. Findings
from these studies suggest that appropriate use of antibiotics may
reduce the risk of SSI following appendectomy by 40-60%. Moreover,
prophylactic use of antibiotics shortens the hospital stay as well. It is
further elaborated that prevention of wound infection is associated
with faster return to normal activity afer discharge from hospital [18-
20].
Preoperative use of antibiotics and surgical technologies are highly
valuable aspects of care in major surgical procedures. However, it is
emphasized that preventive measures for SSI are more or less unrealistic.
Tis notion is because of certain unchangeable risk factors such as
comorbid diseases, prolong hospital stay and type of surgery [18-21].
Hence, a patient should be provided with abolition of all preventable
infections by adopting evidence based actions. Te Center for Disease
Control (CDC) recommends prophylactic use of antibiotic for either
surgical incision or wounds [18]. If the antibacterial regimen does
not sufciently cover all microorganisms, supplementary prophylaxis
regimen should be considered e.g. provided the risk of methicilin
resistant Staphylococoous aurus (MRSA) is highly susceptible and
the prescribed regimen does not cover MRSA, vancomycin may be
recommended.
Variation in the practice of surgical antibiotic prophylaxis is quite
evident in Malaysia. Lim and colleagues conducted a study in seven
hospitals of Malaysia and found that diferent antibiotic regimens
were used for among various surgical procedures. Majority (70%)
of antibiotics were prescribed to patients where such prophylaxis
was probably not necessary. Moreover, when prescribed, antibiotics
were given for durations that were longer than necessary. Lim and
colleagues emphasized implementation of guidelines so as to improve
the practices of health care professionals. Tey further highlighted
standardization of surgical prophylactic regimens in context of cost
reduction and emergence of antibiotic resistance [22]. Meanwhile,
a survey conducted among the Ministry of Health Oral Surgery
units showed a wide variation in the choice of antibiotics used for
surgical prophylaxis. Extensive use of metronidazole and broad
spectrum antibiotics (Ampicillin, Amoxycillin, 2
nd
and 3
rd
generation
Cephalosporins etc) was profoundly observed in it [23]. Another
survey carried among Dental Ofcers in Pahang and Malacca states of
Malaysia revealed that a signifcant number of Dental Ofcers did not
understand the meaning of antibiotic prophylaxis. Respondents of the
survey were further found to be unaware with the drug and regimen
usage [23]. Apart from abovementioned issues, Mazza reported
the economic burden of common antibiotics that were prescribed
prophylactically for infection in Malaysia. Analysis was made on the
basis of cost of selected antibiotic and their therapeutic group which
was further compared on surgical procedure [21,24]. Tey found that
long acting antibiotics afected the cost to therapy.
Te ideal duration of post-operative antibiotics is not clearly defned
although most studies report that there is no additional beneft when
antibiotic prophylaxis was continued beyond 24 hours [1,15,25-26]. In
context of hospital costs related with surgical complications, Dimick
and colleagues established that the increased cost was $1398 per patient
for infectious complications; $7789 per patient for cardiovascular
complications; $52,466 per patient for respiratory complications; and
$1810 per patient for thromboembolic complications [27]. However,
it seems inappropriate to evaluate antimicrobial use based on cost
alone. Inappropriate usage should also bear over- and under-usage
of an antibiotic, burden of mortality rate, the resources consumed
for development of new chemotherapeutic agents against resistant
microorganism [28]. Hence, the exact cost of prophylaxis therapy
should be viewed in consideration with above mentioned outcomes.
On the other hand additional length of stay and charges, and
increase in mortality rate due to patient safety events in the hospital can
be attributed to postoperative complications [29]. Recent analysis of
data from the Veterans Health Administration (VA) National Surgical
Quality Improvement Project (NSQIP) confrmed that occurrence of
any complication within 30 days of postoperative duration reduced
median patient survival by 69% [30]. Such immense reduction in survival
