The Impact of Quality Improvement Interventions in Improving Surgical Infections and Mortality in Low and Middle-Income Countries: A Systematic Review and Meta-Analysis

Jin J, Akau Ola S, Yip CH, Nthumba P, Ameh EA, de Jonge S, et al.

World J Surg, 2021 10;45(10):2993-3006.
PMID: 34218314 DOI: 10.1007/s00268-021-06208-y

BACKGROUND: Morbidity and mortality in surgical systems in low- and middle-income countries (LMICs) remain high compared to high-income countries. Quality improvement processes, interventions, and structure are essential in the effort to improve peri-operative outcomes.
METHODS: A systematic review and meta-analysis of interventional studies assessing quality improvement processes, interventions, and structure in developing country surgical systems was conducted according to the Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies were included if they were conducted in an LMIC, occurred in a surgical setting, and measured the effect of an implementation and its impact. The primary outcome was mortality, and secondary outcomes were rates of rates of hospital-acquired infection (HAI) and surgical site infections (SSI). Prospero Registration: CRD42020171542.
RESULT: Of 38,273 search results, 31 studies were included in a qualitative synthesis, and 28 articles were included in a meta-analysis. Implementation of multimodal bundled interventions reduced the incidence of HAI by a relative risk (RR) of 0.39 (95%CI 0.26 to 0.59), the effect of hand hygiene interventions on HAIs showed a non-significant effect of RR of 0.69 (0.46-1.05). The WHO Safe Surgery Checklist reduced mortality by RR 0.68 (0.49 to 0.95) and SSI by RR 0.50 (0.33 to 0.63) and antimicrobial stewardship interventions reduced SSI by RR 0.67 (0.48-0.93).
CONCLUSION: There is evidence that a number of quality improvement processes, interventions and structural changes can improve mortality, HAI and SSI outcomes in the peri-operative setting in LMICs.

Yeap JS, Lim JW, Vergis M, Au Yeung PS, Chiu CK, Singh H

Med J Malaysia, 2006 Jun;61(2):181-8.
PMID: 16898309

The national clinical practice guideline has recommended that prophylactic antibiotic be given in orthopaedic surgery involving joint replacements and internal fixation of fractures. The aim of this study is to assess the current antibiotics prophylaxis practice in a state level hospital. One hundred and three patients (68 males, 35 females; mean age 41.6 +/- 22.2 years) undergoing internal fixation for closed fractures and joint replacement surgery were included in this prospective study. The choice of pre and post-operative antibiotics, their dosages and duration of administration were recorded. The pre-operative antibiotics were only deemed to have been given if it was documented in the case notes and in the case of post-operative antibiotics if it was signed on the drug chart. Eighty eight percent were given pre-operative prophylactic antibiotics and 92% were given post-operative antibiotics. For patients undergoing internal fixation of fractures, the most commonly used antibiotic for both pre and post-op is intravenous cefuroxime. For joint replacement surgery, the most commonly used antibiotic is intravenous cefoperazone. The duration or number of doses of post-operative antibiotics was highly variable. It was not stated in 56% of the post-operative instructions. Post-operative antibiotic was ordered for 48 hours or longer in 10%. In conclusion, prophylactic antibiotics appear to be widely practised. The first line antibiotics as recommended by the present guideline were not given in any of the patients. Second generation followed by third generation cephalosporins are the most popular antibiotics, with a trend towards using third generation cephalosporins in arthroplasty patients. Single dose prophylaxis was rarely practised.

Abdullah J, Rushdan A, Hamzah M, Ariff AR, Rani A

Ann. Transplant., 1999;4(3-4):28-31.
PMID: 10853777

Four patients underwent reconstruction of anterior cranial fossa of skull defects between November 1997 and January 1998. All of them had traumatic anterior cranial fossa defect and were reconstructed with lyophilised bovine cortical bone graft. There was no cerebrospinal fluid leakage, meningitis, extradural abscess or other infections. This study demonstrates that the use of bovine bone graft in the reconstruction of anterior base defects is safe.

Fulltext The role of prophylactic antibiotics in caesarean section--a randomised trial

Ng NK, Sivalingam N

Med J Malaysia, 1992 Dec;47(4):273-9.
PMID: 1303479

A prospective randomised controlled study was conducted over a 6 month period on the value of administering prophylactic antibiotics in patients undergoing emergency caesarean section at the Ipoh General Hospital. A total of 222 patients were randomised to receive 24 hours of ampicillin (500 mg per dose), cefoperazone (1 gm per dose) or no antibiotics. In all parameters of patient morbidity, the group receiving cefoperazone showed significantly better results as compared to the group not receiving antibiotics. The ampicillin group also had favourable results but generally not achieving statistical significance. Prophylactic antibiotics appear to be beneficial and consideration should be given to make it a routine in all emergency caesarean sections.

Fulltext The incidence of post-operative wound infection in orthopaedic surgery

Dhillon KS, Kok CS

Med J Malaysia, 1995 Sep;50(3):237-40.
PMID: 8926901

With the increase in the number of orthopaedic surgeons and the aggressive marketing by manufacturing companies, high technology orthopaedic surgery is being more frequently carried out in Malaysia. Post-operative sepsis complicating this type of surgery can have disastrous consequences. No data is available in this country on the incidence of post-operative infection in Orthopaedic Surgery. The aim of this study was to determine the incidence of post-operative infection. A retrospective survey of 703 patients undergoing elective Orthopaedic Surgery in the year 1991 was carried out. We found an overall post-operative infection rate of 6.8% and a deep infection rate of 3.3%. This figure of 3.3% is higher than the internationally accepted figure of less than 2%. A need for ongoing surveillance and concerned effort to reduce the infection rate is stressed.

Fulltext Povidone iodine in wound healing: A review of current concepts and practices

Bigliardi PL, Alsagoff SAL, El-Kafrawi HY, Pyon JK, Wa CTC, Villa MA

Int J Surg, 2017 Aug;44:260-268.
PMID: 28648795 DOI: 10.1016/j.ijsu.2017.06.073

BACKGROUND: Of the many antimicrobial agents available, iodophore-based formulations such as povidone iodine have remained popular after decades of use for antisepsis and wound healing applications due to their favorable efficacy and tolerability. Povidone iodine's broad spectrum of activity, ability to penetrate biofilms, lack of associated resistance, anti-inflammatory properties, low cytotoxicity and good tolerability have been cited as important factors, and no negative effect on wound healing has been observed in clinical practice. Over the past few decades, numerous reports on the use of povidone iodine have been published, however, many of these studies are of differing design, endpoints, and quality. More recent data clearly supports its use in wound healing.
METHODS: Based on data collected through PubMed using specified search criteria based on above topics and clinical experience of the authors, this article will review preclinical and clinical safety and efficacy data on the use of povidone iodine in wound healing and its implications for the control of infection and inflammation, together with the authors' advice for the successful treatment of acute and chronic wounds.
RESULTS AND CONCLUSION: Povidone iodine has many characteristics that position it extraordinarily well for wound healing, including its broad antimicrobial spectrum, lack of resistance, efficacy against biofilms, good tolerability and its effect on excessive inflammation. Due to its rapid, potent, broad-spectrum antimicrobial properties, and favorable risk/benefit profile, povidone iodine is expected to remain a highly effective treatment for acute and chronic wounds in the foreseeable future.

Does the use of amoxicillin/amoxicillin-clavulanic acid in third molar surgery reduce the risk of postoperative infection? A systematic review with meta-analysis

Menon RK, Gopinath D, Li KY, Leung YY, Botelho MG

Int J Oral Maxillofac Surg, 2019 Feb;48(2):263-273.
PMID: 30145064 DOI: 10.1016/j.ijom.2018.08.002

The objectives of this systematic review were to investigate the efficacy of amoxicillin/amoxicillin-clavulanic acid for reducing the risk of postoperative infection after third molar surgery and to evaluate the adverse outcomes in these patients, as well as in healthy volunteers. A systematic search of four databases was performed on May 26, 2017. Eleven studies qualified for the qualitative analysis and eight were found suitable for meta-analysis. The results suggest that both amoxicillin-clavulanic acid and amoxicillin significantly reduce the risk of infection after third molar extraction (overall relative risk (RR) 0.25, P<0.001). However, with the exclusion of randomized controlled trials with a split-mouth design (due to an inadequate crossover period after antibiotic treatment), only amoxicillin-clavulanic acid was found to be effective (RR 0.21, P<0.001). The risk of adverse effects was significantly higher in the amoxicillin-clavulanic acid group (RR=4.12, P=0.023) than in the amoxicillin group (RR 1.57, P=0.405). In conclusion, amoxicillin-clavulanic acid and amoxicillin may significantly reduce the risk of infection after third molar extraction. However, their use in third molar surgery should be viewed with caution, as recent clinical trials on healthy volunteers have shown evidence of the negative impact of amoxicillin use on bacterial diversity and antibiotic resistance.

Initiatives to reduce postoperative surgical site infections of the head and neck cancer surgery with a special emphasis on developing countries

Haque M, McKimm J, Godman B, Abu Bakar M, Sartelli M

Expert Rev Anticancer Ther, 2019 01;19(1):81-92.
PMID: 30394844 DOI: 10.1080/14737140.2019.1544497

Introduction: Surgery in patients with head and neck cancers is frequently complicated by multiple stages of procedure that includes significant surgical removal of all or part of an organ with cancer, tissue reconstruction, and extensive neck dissection. Postoperative wound infections, termed 'surgical site infections' (SSIs) are a significant impediment to head-and-neck cancer surgery and recovery, and need to be addressed. Areas covered: Approximately 10-45% of patients undergoing head-and-neck cancers surgery develop SSIs. SSIs can lead to delayed wound healing, increased morbidity and mortality as well as costs. Consequently, SSIs need to be avoided where possible, as even the surgery itself impacts on patients' subsequent activities and their quality of life, which is exacerbated by SSIs. Several risk factors for SSIs need to be considered to reduce future rates, and care is also needed in the selection and duration of antibiotic prophylaxis. Expert commentary: Head and neck surgeons should give personalized care especially to patients at high risk of SSIs. Such patients include those who have had chemoradiotherapy and need reconstructive surgery, and patients from lower and middle-income countries and from poorer communities in high income countries, who often have high levels of co-morbidity because of resource constraints.

Fulltext APSIC guidelines for the prevention of surgical site infections

Ling ML, Apisarnthanarak A, Abbas A, Morikane K, Lee KY, Warrier A, et al.

Antimicrob Resist Infect Control, 2019;8:174.
PMID: 31749962 DOI: 10.1186/s13756-019-0638-8

Background: The Asia Pacific Society of Infection Control (APSIC) launched the APSIC Guidelines for the Prevention of Surgical Site Infections in 2018. This document describes the guidelines and recommendations for the setting prevention of surgical site infections (SSIs). It aims to highlight practical recommendations in a concise format designed to assist healthcare facilities at Asia Pacific region in achieving high standards in preoperative, perioperative and postoperative practices.
Method: The guidelines were developed by an appointed workgroup comprising experts in the Asia Pacific region, following reviews of previously published guidelines and recommendations relevant to each section.
Results: It recommends that healthcare facilities review specific risk factors and develop effective prevention strategies, which would be cost effective at local levels. Gaps identified are best closed using a quality improvement process. Surveillance of SSIs is recommended using accepted international methodology. The timely feedback of the data analysed would help in the monitoring of effective implementation of interventions.
Conclusions: Healthcare facilities should aim for excellence in safe surgery practices. The implementation of evidence-based practices using a quality improvement process helps towards achieving effective and sustainable results.

Identifying Risk Factors for Surgical Site Infection After Stoma Closure in Infants for Targeted Implementation of Surgical Site Infection Reduction Bundle

Nwachukwu I, Visa A, Holbrook C, Tan YW

Surg Infect (Larchmt), 2024 Apr;25(3):185-191.
PMID: 38394295 DOI: 10.1089/sur.2023.248

Background: To determine risk factors for surgical site infection (SSI) in infants after stoma closure, to identify at-risk patients, plan timing of surgery, and implement SSI-reduction strategies. Patients and Methods: A single center retrospective comparison study of all children less than one year of age who underwent enterostomy closure (2018-2020) with SSI diagnosed through a prospective surveillance program, using criteria from Public Health England (PHE). Demographics and risk factors, types of SSI, systemic sepsis, mortality and length of stay were compared between SSI and non-SSI. Significant factors associated with SSI were analyzed in a multivariate binomial logistic regression model. Results: Eighty-nine stoma closures were performed, most commonly for necrotizing enterocolitis (NEC) and anorectal malformation. Fourteen had SSI (16%): 12 superficial and two deep; three developed systemic sepsis, but no 30-day mortality. Surgical site infection was associated with NEC (12/14 vs. 32/75; p = 0.003), younger age (median 76 vs. 89 days; p = 0.014), lower corrected gestation (cutoff: 39 weeks gestation; 11/14 vs. 27/75; p = 0.004) and lower weight (cutoff: 2.2 kg; 7/14 vs. 16/75; p = 0.032), compared with non-SSI. After correcting for age, gestation, and weight, logistic regression showed NEC was an independent predictor for SSI (odds ratio [OR], 12; 95% confidence interval [CI],1.2-125). The at-risk cohort (n = 56; 63%) had seven-fold increased risk of SSI and four-fold longer hospital stay, which may be the target for SSI-reduction strategies. Conclusions: Necrotizing enterocolitis-related stoma closure is at increased risk for SSI. Considerations for delaying stoma closure until achieving 39 weeks gestation or 2.2 kg in weight may further reduce SSI. Targeting SSI-reduction strategies using these criteria may improve resource-rationalization.

Oh AL, Goh LM, Nik Azim NA, Tee CS, Shehab Phung CW

J Infect Dev Ctries, 2014 Feb;8(2):193-201.
PMID: 24518629 DOI: 10.3855/jidc.3076

INTRODUCTION: The widespread and inappropriate use of broad-spectrum antibiotics in surgical prophylaxis has led to reduced treatment efficacy, increased healthcare costs, and antibiotic resistance. This study aimed to explore the adherence of antibiotic usage in surgical prophylaxis to the national antibiotic guideline and the incidences of surgical site infection (SSI).
METHODOLOGY: A three-month prospective observational study has been conducted in the surgical wards of Sarawak General Hospital (SGH) using a standardized surveillance form. Each patient was reviewed for up to 30 days post-operatively to determine the occurrence of SSI.
RESULTS: A total of 87 patients were included within the study period. The majority of the cases were clean-contaminated wounds (60.9%). Most were hepatobiliary cases (37.9%), followed by colorectal cases (19.5%). The most preferred antibiotic used was cefoperazone (63.2%). The choices of antibiotics in 78.2% of the cases were consistent with the guideline. Around 80% of prophylactic antibiotics were given within one hour before operation and 27.6% were omitted from intraoperative re-dosing. Prophylactic antibiotics were discontinued within 24 hours post-operatively in 77% of the cases. Of those continued for > 24 hours, the majority (60%) were administered for unknown reasons. SSI was documented in 13.8% of the total cases studied. However, there was no significant association between choices of antibiotics and timing of surgical prophylaxis with SSI (p = 0.299 and p = 0.258 respectively).
CONCLUSION: Overall guideline adherence rate was more than 70%. Areas of non-concordance to the guideline require further investigation.

ALEXIS O-Ring wound retractor vs conventional wound protection for the prevention of surgical site infections in colorectal resections(1)

Cheng KP, Roslani AC, Sehha N, Kueh JH, Law CW, Chong HY, et al.

Colorectal Dis, 2012 Jun;14(6):e346-51.
PMID: 22568647 DOI: 10.1111/j.1463-1318.2012.02943.x

Surgical site infection (SSI) remains a common postoperative morbidity, particularly in colorectal resections, and poses a significant financial burden to the healthcare system. The omission of mechanical bowel preparation, as is performed in enhanced recovery after surgery programmes, appears to further increase the incidence. Various wound protection methods have been devised to reduce the incidence of SSIs. However, there are few randomized controlled trials assessing their efficacy. The aim of this study is to investigate whether ALEXIS wound retractors with reinforced O-rings are superior to conventional wound protection methods in preventing SSIs in colorectal resections.

PMID: 19321405 DOI: 10.1016/S1015-9584(09)60011-7

Antibiotic prophylaxis for inguinal hernioplasty is still practiced in many hospitals to prevent consequences of infected mesh, mesh removal and hernia recurrence. The common route of administration is intravenous. However this method can be associated with systemic side effects. Alternatively, locally applied antibiotics have been used and proven to significantly reduce the infection rate after inguinal hernioplasty.

Gul YA, Lian LH, Jabar FM, Moissinac K

ANZ J Surg, 2002 Apr;72(4):275-8.
PMID: 11982514

Antibiotics are often administered in elective colorectal surgery to prevent wound infection. The tendency for surgeons to prolong the administration of prophylactic antibiotic therapy in the postoperative period is a well-known fact. The aim of this study was to elucidate the pattern of prophylactic antibiotic utilization in elective colorectal surgery and to determine if evidence-based medicine is employed in relation to this practice.

Fulltext The use of surgical antibiotic prophylaxis in seven Malaysian hospitals

Lim VK, Cheong YM, Suleiman AB

Southeast Asian J. Trop. Med. Public Health, 1994 Dec;25(4):698-701.
PMID: 7667716

A survey on the use of antibiotics in surgical prophylaxis was carried out in seven Malaysian hospitals. Details of antibiotic prescriptions were obtained through questionnaires completed by the prescriber. A total of 430 such prescriptions was analysed. A large number of different antibiotic regimens were used for a variety of surgical procedures. The majority of prescriptions (70%) were issued for procedures where such prophylaxis was probably not necessary. Antibiotics were also often prescribed for durations that were longer than necessary. There is an urgent need to educate surgeons and standardize surgical prophylactic regimens in order to reduce cost and combat the emergence of antibiotic resistance.

Utilization of surgical antibiotic prophylaxis for obstetrics and gynaecology surgeries in Northern Nigeria

Abubakar U, Syed Sulaiman SA, Adesiyun AG

Int J Clin Pharm, 2018 Oct;40(5):1037-1043.
PMID: 30054786 DOI: 10.1007/s11096-018-0702-0

Background Audit of antibiotic prophylaxis is an important strategy used to identify areas where stewardship interventions are required. Objectives To evaluate compliance with surgical antibiotic prophylaxis in obstetrics and gynaecology surgeries and determine the Defined Daily Dose (DDD) of antibiotic. Settings Three public tertiary hospitals located in Northern Nigeria. Methods This prospective study included women who had obstetrics and gynaecology surgeries with no infection at the time of incision. Appropriateness of antibiotic prophylaxis was determined by a clinical pharmacist. DDD of antibiotics was determined using ATC/DDD index 2017 from the World Health Organization Collaborating Centre for Drugs Statistics Methodology. Main outcome measure Compliance with antibiotic prophylaxis and DDD of antibiotic per procedure. Results A total of 248 procedures were included (mean age: 31.7 ± 7.9 years). Nitroimidazole in combination with either beta-lactam/beta-lactamase inhibitor or third generation cephalosporin were the most prescribed antibiotics. Redundant anaerobic antibiotic combination was detected in 71.4% of the procedures. Timing of antibiotic prophylaxis was optimal in 16.5% while duration of prophylaxis was prolonged in all the procedures (mean duration was 8.7 ± 1.0 days). The DDD of antibiotics prophylaxis was 16.75 DDD/procedure. Antibiotic utilisation was higher in caesarean section and myomectomy (17.9 DDD/procedure) than hysterectomy (14.5 DDD/procedure); P

Comparative evaluation of bioburden and sterility of indigenously prepared bone allograft with and without gentamicin

Makker K, Lamba AK, Faraz F, Tandon S, Sheikh Ab Hamid S, Aggarwal K, et al.

Cell Tissue Bank, 2019 Jun;20(2):243-253.
PMID: 30903410 DOI: 10.1007/s10561-019-09763-w

During bone allograft processing, despite stringent donor screening and use of aseptic techniques, microbial invasion may occur due to the porous nature of the graft and cause potentially fatal infections. The aim of the present study was to prepare bone allograft with and without gentamicin and to compare bioburden and sterility in the obtained grafts to evaluate the role of antibiotic in enhancing graft safety. Fifty samples of demineralized freeze-dried bone allograft were prepared from suitable donors according to international standards. Randomly selected 25 samples were placed in 8 mg gentamicin/gram bone solution for 1 h. Packaging and sealing was done to ensure no microbial ingress during transportation. 40 samples were selected for bioburden testing. Remaining 10 were subjected to 25 kGy gamma radiation and tested for sterility. Microbiological evaluation revealed no evidence of colony forming units in all the samples of both the groups (Bioburden = 0). Post-radiation sterility testing also revealed no bacterial colony in the tested samples from both the groups. Favorable results validate the processing protocol while comparable results in both groups indicate no additive benefit of gentamicin addition. Nil bioburden may be used in further studies to determine a lower radiation dose to achieve adequate sterility and minimize the disadvantages of radiation like collagen cross-linking and decreased osteoinductive capacity.

Fulltext Impact of pharmacist-led antibiotic stewardship interventions on compliance with surgical antibiotic prophylaxis in obstetric and gynecologic surgeries in Nigeria

Abubakar U, Syed Sulaiman SA, Adesiyun AG

PLoS One, 2019;14(3):e0213395.
PMID: 30845240 DOI: 10.1371/journal.pone.0213395

BACKGROUND: Inappropriate and excessive use of surgical antibiotic prophylaxis are associated with the emergence of antibiotic resistance. Antibiotic prophylaxis malpractices are common in obstetrics and gynecology settings and antibiotic stewardship is used to correct such malpractice.
OBJECTIVE: To evaluate the impact of antibiotic stewardship interventions on compliance with surgical antibiotic prophylaxis practice in obstetrics and gynecology surgeries.
METHOD: A prospective pre- and post-intervention study was conducted in two tertiary hospitals between May and December 2016. The duration of the each period was 3 months. Antibiotic stewardship interventions including development of a protocol, educational meeting and audit and feedback were implemented. Data were collected using the patient records and analyzed with SPSS version 23.
RESULTS: A total of 226 and 238 surgical procedures were included in the pre- and post-intervention periods respectively. Age, length of stay and estimated blood loss were similar between the two groups. However, specialty and surgical procedures varied significantly. There was a significant increase in compliance with timing (from 14.2% to 43.3%) and duration (from 0% to 21.8%) of surgical antibiotic prophylaxis after the interventions. The interventions significantly reduced the prescription of third generation cephalosporin (-8.6%), redundant antibiotic (-19.1%), antibiotic utilization (-3.8 DDD/procedure) and cost of antibiotic prophylaxis (-$4.2/procedure). There was no significant difference in the rate of surgical site infection between the two periods. Post-intervention group (OR: 5.60; 95% CI: 3.31-9.47), elective surgery (OR: 4.62; 95% CI: 2.51-8.47) and hospital attended (OR: 9.89; 95% CI: 5.66-17.26) were significant predictors of compliance with timing while elective surgery (OR: 12.49; 95% CI: 2.85-54.71) and compliance with timing (OR: 58.55; 95% CI: 12.66-270.75) were significantly associated with compliance to duration of surgical antibiotic prophylaxis.
CONCLUSION: The interventions improve compliance with surgical antibiotic prophylaxis and reduce antibiotic utilization and cost. However, there is opportunity for further improvement, particularly in non-elective surgical procedures.
