Incidence and predictors of surgical site infection in Ethiopia: prospective cohort

Development and validation of a predictive nomogram for surgical site infection among general surgery patients in Amhara region Ethiopia

Surgical site infections (SSIs) remain a significant cause of morbidity, prolonged hospital stays, and increased healthcare costs, particularly in low-resource settings such as Ethiopia. While SSIs are widely recognized as preventable, the burden of these infections remains high, especially in sub-Saharan Africa, where healthcare resources are limited, and surgical care may not consistently meet recommended standards. In Ethiopia, as in many similar settings, the lack of robust, context-specific predictive tools limits the ability of healthcare providers to proactively manage SSI risks. Current predictive models and nomograms for SSI risk are generally developed in high-resource settings and may not accurately capture the unique risk factors in Ethiopia. The aim of this study was Development and validation of nomogram for Surgical Site Infection Prediction Among General Surgery Patients in Amhara. A prospective follow-up study was conducted involving general surgery patients at referral hospitals in the Amhara region. Predictors of SSIs were identified through logistic regression analysis, and a nomogram was constructed based on these predictors. The model was internally validated using bootstrapping techniques to assess the accuracy and reliability of the risk estimates. Model performance was evaluated in terms of discrimination, measured by the area under the receiver operating characteristic (ROC) curve (AUC), and calibration, using calibration plots. The incidence of SSI was 39.6%. The key prognostic predictors of this model were: sex, age, diabetes mellitus (DM), wound classification, wound care, American Society of Anesthesiologists (ASA) score, residence, surgery duration, preoperative hospital stays, alcohol consumption, and prior surgical history. The model's discrimination power was 90.1% with 95% CI (87-93%) and its calibration is well fitted with 45 degrees. The bootstrapped model produced consistent β coefficients, supporting the stability and robustness of the model. The nomogram was developed with key predictors of SSI and demonstrated excellent discrimination ability, with an AUC of 0.87 (95% CI: 0.84-0.91). Calibration plots showed a strong agreement between predicted and observed probabilities, indicating the model is well-calibrated. The incidence of SSI was notably high. American Society of Anesthesiologists (ASA) score, sex, age, diabetes mellitus (DM), wound classification, wound care practices, patient residence, surgery duration, preoperative hospital stay, alcohol use, and history of previous surgeries were key prognostic predictors. The validated model had an excellent discrimination power with well fitted calibration. The developed nomogram accurately predicts the risk of SSIs among general surgery patients. It might serve as a practical tool for identifying high-risk patients, enabling healthcare providers to implement targeted preventive measures, improving patient outcomes and reducing the burden of SSIs in Ethiopian healthcare settings. Further external validation is recommended to confirm the model's applicability across different settings.

Impact of surgical site infection on short- and long-term outcomes of robot-assisted rectal cancer surgery: a two-center retrospective study

PURPOSE

Robot-assisted surgery has increasingly gained recognition in the treatment of rectal cancer. This study aimed to assess the incidence of surgical site infection (SSI) that underwent robot-assisted radical rectal cancer surgery and to evaluate their influence on patient outcomes.

METHODS

A retrospective analysis was conducted on 360 patients who underwent robot-assisted radical rectal cancer surgery between 2017 and 2024 at Fujian Medical University Union Hospital and Longyan First Affiliated Hospital of Fujian Medical University. The patients were categorized into surgical site infection and non-surgical site infection groups based on the presence of surgical site infection. Baseline clinicopathological characteristics, perioperative details, and follow-up data were analyzed. Univariate and multivariate logistic regression analyses were performed to identify independent predictors of surgical site infection, and Cox proportional hazards regression models were utilized to evaluate factors influencing overall survival.

RESULTS

The study found that 44 out of 360 patients (12.2%) developed surgical site infection. Multivariate analysis indicated that positive perineural invasion (OR 3.59, 95% CI 1.50-8.62, P = 0.004) is an independent risk factor for SSI. Low anterior resection (OR 0.26, 95% CI 0.09-0.73, P = 0.011), preservation of the left colonic artery (OR 0.20, 95% CI 0.09-0.44, P < 0.001), and neoadjuvant therapy (OR 0.45, 95% CI 0.23-0.89, P = 0.021) were associated with reduced risks of SSI. The presence of SSI was significantly associated with a reduction in overall survival (HR 3.43, 95% CI 1.30-9.04, P = 0.012). The risk of developing surgical site infection increases with the number of risk factors, and patients with two or more risk factors have a much higher risk of developing SSI.

CONCLUSIONS

This study identified perineural invasion as an independent risk factor for the development of SSI that underwent robot-assisted radical rectal cancer surgery. Low anterior resection, preservation of the left colonic artery, and neoadjuvant therapy emerged as protective factors. Moreover, the presence of surgical site infection was significantly correlated with poorer overall survival.

Bacterial surgical site infections: prevalence, antimicrobial susceptibility patterns, and associated risk factors among patients at Bule Hora University Teaching Hospital, Southern Ethiopia

Objectives

Surgical site infections occur within 30 days of an invasive surgical procedure in the parts of the body where the surgery is performed. Therefore, this study aimed to determine the prevalence, antimicrobial susceptibility patterns, and associated risk factors of surgical site infections at Bule Hora University Teaching Hospital, Southern Ethiopia.

Methods

An institution-based cross-sectional study was conducted with 183 consecutively enrolled participants between 1 January and 30 June 2023. Microbiological identification and antimicrobial susceptibility testing of the organisms isolated from clinical samples were performed aseptically. Data were collected using a questionnaire and analysed using SPSS version 26.

Results

The overall prevalence of surgical site infections was 15.8% (95% CI, 10.9-22). The predominant isolate was Staphylococcus aureus (n = 14; 34.1%). There were 18 (43.9%) multidrug-resistant isolates. Age group >54 (adjusted odds ratio [AOR] = 4.76, 95% CI, 1.10-20.560), hospital stay ≥10 days (AOR = 2.66, 95% CI, 1.06-6.66],), operation duration ≥2 hours (AOR = 2.64, 95% CI, 1.01-6.90), clean-contaminated wound (AOR = 3.17, 95% CI, 1.21-8.30), open surgical site (AOR = 2.64, 95% CI, 1.02-6.86), and malnutrition (AOR = 4.3, 95% CI, 1.42-12.97) were significantly associated with surgical site infections.

Conclusions

The prevalence of surgical site infections and multidrug-resistant isolates is higher compared with World Health Organisation reports or previous studies. This finding emphasises the need for routine screening and antimicrobial susceptibility testing to prevent and control site infections.

Surgical site infections following abdominal surgery: incidence, risk factors and outcomes

Background

Abdominal surgeries especially open surgeries are associated with high risk of surgical site infections. This invariably leads to increased morbidity, prolonged hospital stay with its attendant financial burden and mortality.

Objectives

To describe the incidence, risk factors and outcome in patient with surgical site infection following open abdominal surgery.

Methods

This was a prospective study involving consecutive 100 patients across surgical sub-specialties and gynaecology over 6 month period. Variables analyzed included; biodata, type of surgery, American Society of Anaesthesiologists (ASA) grade, hair removal at wound site, specialty, degree of intraoperative contamination, presence of surgical site infection (SSI) and mortality.

Results

Majority of the patients (64%) were women and the age range was 11 to 73 years, mean age was 36.41 ± 10.9 years. About 60% of the cases were emergency procedures, indication for surgery were benign in 89 (89%) patients, malignant in 7% and trauma in 4%. Majority (55%) had clean-contaminated wounds while 45% had contaminated and dirty wounds, 54% were solely general surgery patients, 66% of the patients had hair removal before theatre arrival. SSI was recorded in 20% of the patients and mortality rate was 7% at 30 days follow up.The risk of SSI was higher in emergency procedures, (p =0.041) with an odd ratio of 2. SSI risk increases with the ASA grade, general surgical procedures, hair removal at wound site before theatre arrival and also in contaminated and dirty wounds. Emergency procedures and SSI were found to increase the odds of mortality.

Conclusion

Emergency procedures, general surgery (bowel surgeries), and significant degrees of intraoperative contamination are associated with higher risk of SSI, which is an independent predictor of mortality. More efforts should be put in place to prevent SSI in these categories of patients.

Predictors of Post-Caesarean Surgical Site Infections at Mubende Regional Referral Hospital, Central Uganda: Prospective Cohort Study (July-September 2023)

Background

Post-caesarean surgical site infections (PCSSIs) significantly impact maternal morbidity, mortality, and healthcare costs in low- and middle-income countries, particularly in sub-Saharan Africa, where preventive measures are often inadequate. Despite this burden, data on PCSSIs in this context are limited. This study aimed to evaluate the incidence and factors associated with PCSSIs at Mubende Regional Referral Hospital.

Methods

This prospective cohort study included 204 women who underwent caesarean sections from July to September 2023. Data was collected and participants were monitored for up to 28 days post-delivery to identify occurrences of surgical site infections (SSIs). Statistical analysis was conducted using STATA, with significance defined as a p-value of < 0.05.

Results

Most participants (63.2%) were aged 18-35 years, with over 67% having a parity of ≤4. Preoperative antibiotics were administered to 77.5% of participants. Most surgeries (64.2%) lasted 1-2 hours, and the overall incidence of surgical site infections (SSIs) was 16.18%. Significant risk factors associated with more than a twofold increase in SSI risk included unstable referral status (aRR = 2.02), obstructed labor (aRR = 2.97), chorioamnionitis (aRR = 2.73), and prolonged premature rupture of membranes (PROM) (aRR = 2.05). Prolonged labor increased SSI risk by 1.37-fold (aRR = 1.37), while receipt of preoperative antibiotics was linked to a reduced SSI risk (aRR = 0.77).

Conclusion

The post-caesarean SSI rate at Mubende Regional Referral Hospital is notably high, with key risk factors including unstable referral status, obstructed labor, prolonged labor, chorioamnionitis, and prolonged premature rupture of membranes (PROM). Administering preoperative antibiotics 30 minutes to 1 hour prior to surgery is linked to a reduced risk of SSI.

Comparison of the Incidence of Surgical Site Infection in Abdominal Wound Closure: Antibiotic-Coated Polyglactin 910 Suture Versus Polyglactin Suture With Local Infiltration of Antibiotic Along the Incision Line

Aim and objectives The purpose of this study is to compare the incidence of surgical site infection (SSI) rates in abdominal wound closure utilizing antibacterial-coated (triclosan-coated) suture material versus conventional suture material with subcutaneous antibacterial infiltration along the incision line. Materials and method This prospective and comparative (randomized, non-blinded clinical trial) was conducted at the Postgraduate Department of Surgery, Swaroop Rani Nehru Hospital, associated with Motilal Nehru Medical College, Prayagraj, India. The sample size was calculated to be one hundred. The patients in Group A underwent laparotomy using polyglactin 910 coated with triclosan. The patients in Group B underwent normal suture closure and local infiltration of broad-spectrum antibiotics (1 gram of ceftriaxone in 10 ml distilled water, along with the incision). Results There was no discernible difference between the various groups on postoperative day (POD) 14, 21, and 30. In Group A, 100.0% of individuals had healed wound status (POD 30). Group B had healed wound status among the 96.0% of members (POD 30). Twenty percent of the people in Group A had SSI whereas 38.0% of the participants in Group B had SSI. There was no discernible difference between the two groups regarding the distribution of culture (χ² = 7.741, p = 0.127). Conclusion Triclosan-coated sutures are more effective than subcutaneous antibiotic infiltration along the incision line in lowering the frequency of SSI during primary laparotomy wound closure.

Identification of predictive factors for surgical site infections in gastrointestinal surgeries: A retrospective cross-sectional study in a resource-limited setting

Background

Surgical site infection (SSI), albeit infrequent, drastically impacts the quality of care. This article endeavors to investigate the predictive factors of SSIs following surgical interventions that involve the gastrointestinal (GI) tract within a single institution in a resource-limited setting.

Methods

Over seven years from June 2015 to June 2022, patients who underwent GI surgery and developed SSI were retrospectively matched with an unaffected case-control cohort of patients. Standardized techniques for wound culture, laboratory evaluation of bacterial isolates, and antibiotic susceptibility tests were employed. Logistic regression analysis was utilized to investigate the predictive factors associated with 30-day postoperative SSI occurrence.

Results

A total of 525 patients who underwent GI surgical procedures were included, among whom, 86 (16.4%) developed SSI and the majority of SSIs were superficial (74.4%). Escherichia coli was the most commonly isolated bacterium (54.4%), and a high percentage of multidrug-resistant organisms were observed (63.8%). In multivariate Cox regression analysis, illiteracy (Odds ratio [OR]:40.31; 95% confidence interval [CI]: 9.54-170.26), smoking (OR: 21.15; 95% CI: 4.63-96.67), diabetes (OR: 5.07; 95% CI: 2.27-11.35), leukocytosis (OR: 2.62; 95% CI: 1.24-5.53), hypoalbuminemia (OR: 3.70; 95% CI: 1.35-10.16), contaminated and dirty wounds (OR: 6.51; 95% CI:1.62-26.09), longer operation duration (OR: 1.02; 95% CI: 1.01-1.03), emergency operations (OR: 12.58; 95% CI: 2.91-54.30), and extending antibiotic prophylaxis duration (OR: 3.01; 95% CI: 1.28-7.10) were the independent risk factors for SSI (all p < 0.05).

Conclusions

This study highlights significant predictors of SSI, including illiteracy, smoking, diabetes, leukocytosis, hypoalbuminemia, contaminated and dirty wounds, longer operative time, emergency operations, and extending antibiotic prophylaxis duration. Identifying these risk factors can help surgeons adopt appropriate measures to reduce postoperative SSI and improve the quality of surgical care, especially in a resource-limited setting with no obvious and strict policy for reducing SSI.

Incidence and predictors of postoperative complications in Sub-Saharan Africa: a systematic review and meta-analysis

Background

Postoperative complications remain a significant challenge, especially in settings where healthcare access and infrastructure disparities exacerbate. This systematic review and meta-analysis aimed to determine the pooled incidence and risk factors of postoperative complications among patients undergoing essential surgery in Sub-Saharan Africa (SSA).

Method

PubMed/MEDLINE, EMBASE, CINAHL, Web of Science, and Google Scholar were searched from January 2010 to November 2022 for completed studies reporting the incidence and risk factors associated with postoperative complications among patients undergoing essential surgery in SSA. Severity of postoperative complications was ranked based on the Clavien-Dindo classification system, while risk factors were classified into three groups based on the Donabedian structure-process-outcome quality evaluation framework. Studies quality was appraised using the JBI Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI), and data were analyzed using Comprehensive Meta-Analysis (CMA) software. The study protocol adhered to the PRISMA guidelines and was registered in PROSPERO (CRD42023414342).

Results

The meta-analysis included 19 studies (10 cohort and 9 cross-sectional) comprising a total of 24,136 patients. The pooled incidence of postoperative complications in SSA was 20.2% (95% CI: 18.7%-21.8%), with a substantial heterogeneity of incidence observed. The incidence varied from 14.6% to 27.5% based on the Clavien-Dindo classification. The random-effects model indicated significant heterogeneity among the studies (Q = 54.202, I = 66.791%, p < 0.001). Contributing factors to postoperative complications were: structure-related factors, which included the availability and accessibility of resources, as well as the quality of both the surgical facility and the hospital.; process-related factors, which encompassed surgical skills, adherence to protocols, evidence-based practices, and the quality of postoperative care; and patient outcome-related factors such as age, comorbidities, alcohol use, and overall patient health status.

Conclusion

The meta-analysis reveals a high frequency of postoperative complications in SSA, with noticeable discrepancies among the studies. The analysis highlights a range of factors, encompassing structural, procedural, and patient outcome-related aspects, that contribute to these complications. The findings underscore the necessity for targeted interventions aimed at reducing complications and improving the overall quality of surgical care in the region.

Factors in postoperative length of hospital stay among surgical patients in a rural Ethiopian hospital: an observational study

Introduction

surgical site infection is associated with longer postoperative hospital stays. We explored factors associated with longer postoperative hospital stays among patients in the surgical ward of a primary rural hospital in Ethiopia, where laboratory facilities for microbiological confirmation of surgical site infections were not available.

Methods

an observational study was performed for patients ≥ 18 years of age who underwent elective or emergency surgery from 22nd June 2017 to 19th July 2018. Data were taken from paper-based medical records and patient interviews. The primary outcome was postoperative length of hospital stay. Data were analyzed by multivariable linear regression using Stata software, version 13.

Results

seventy-five patients were enrolled, sociodemographic data was obtained from 14 of these patients by interview, and 44 patients had complete outcome and covariate data and were included in regression analysis. Median length of preoperative hospital stay was 3.0 (interquartile range 2.0) days. Postoperative length of hospital stay was longer by 3.8 days (95% confidence interval (CI) 1.05-6.55; p=0.008), 4.7 days (95% CI 1.64-7.66; p=0.004), and 5.9 days (95% CI 2.70-9.02; p=0.001), for patients 35-54 years, 55-64 years and the 65+ years respectively, compared to patients who were 18-34 years of age. Patients who received preoperative antibiotics stayed 5.3 days longer (95% CI 1.67-8.87; p=0.005) compared to those who were not given preoperative antibiotics.

Conclusion

age and improper use of preoperative antibiotics compound the risk for postoperative length of stay. Infection prevention protocols, including staff training, and surveillance for surgical site infections are critical for improving hospital outcomes.

Posterior cranial vault distraction in children with syndromic craniosynostosis: the era of biodegradable materials-a comprehensive review of the literature and proposed novel global application

Distraction osteogenesis is utilized to increase intracranial volume in the treatment of restrictive pathologies, most commonly syndromic synostosis. Children too young for open calvarial vault expansion or other systemic or local contraindications to a direct reconstructive approach benefit greatly from distraction osteogenesis, typically addressing posterior vault expansion. Wound infection, cerebrospinal fluid (CSF) leak, device failure, need for a second surgery for removal, and cost, are issues that can limit the use of this approach. These challenges are more pronounced in low- and middle-income countries (LMICs) due to lack of access to the device, the financial burden of the need for a second surgery, and the severity of the implications of infection and CSF leak. Over the last five decades, there has been an increased acceptance of bioresorbable instrumentation in craniofacial surgery. Poly L-lactic acid, polyglycolic acid, and polydioxanone are the most commonly used polymers. New resorbable fixation tools such as ultrasound-activated pins and heat-activated pins are superior to conventional bioresorbable screws in allowing attachment to thinner bone plates. In this paper, we present a review of the literature on cranial vault distraction and the use of bioresorbable materials and propose a novel design of a fully absorbable cranial distractor system using external magnetic distraction control, eliminating the need for external activation ports and a second surgery to remove the hardware. The application of this technology in LMIC settings could advance access to care and treatment options for patients with syndromic synostosis.

Prevalence, risk factors, and antimicrobial resistance of endemic healthcare-associated infections in Africa: a systematic review and meta-analysis

BACKGROUND

Healthcare-associated infections (HCAI) place a significant burden on healthcare systems globally. This systematic review and meta-analysis aimed to investigate the prevalence, risk factors, and aetiologic agents of endemic HCAI in Africa.

METHODS

MEDLINE/PubMed, CINAHL, and Global Health databases (EBSCOhost interface) were searched for studies published in English and French describing HCAI in Africa from 2010 to 2022. We extracted data on prevalence of HCAI, risk factors, aetiologic agents, and associated antimicrobial resistance patterns. We used random-effects models to estimate parameter values with 95% confidence intervals for risk factors associated with HCAI. This study was registered in PROSPERO (CRD42022374559) and followed PRISMA 2020 guidelines.

RESULTS

Of 2541 records screened, 92 were included, comprising data from 81,968 patients. Prevalence of HCAI varied between 1.6 and 90.2% with a median of 15% across studies. Heterogeneity (I2) varied from 93 to 99%. Contaminated wound (OR: 1.75, 95% CI: 1.31-2.19), long hospital stay (OR: 1.39, 95% CI: 0.92-1.80), urinary catheter (OR: 1.57, 95% CI: 0.35-2.78), intubation and ventilation (OR: 1.53, 95% CI: 0.85-2.22), vascular catheters (OR: 1.49, 95% CI: 0.52-2.45) were among risk factors associated with HCAI. Bacteria reported from included studies comprised 6463 isolates, with E. coli (18.3%, n = 1182), S. aureus (17.3%, n = 1118), Klebsiella spp. (17.2%, n = 1115), Pseudomonas spp. (10.3%, n = 671), and Acinetobacter spp. (6.8%, n = 438) being most common. Resistance to multiple antibiotics was common; 70.3% (IQR: 50-100) of Enterobacterales were 3rd -generation cephalosporin resistant, 70.5% (IQR: 58.8-80.3) of S. aureus were methicillin resistant and 55% (IQR: 27.3-81.3) Pseudomonas spp. were resistant to all agents tested.

CONCLUSIONS

HCAI is a greater problem in Africa than other regions, however, there remains a paucity of data to guide local action. There is a clear need to develop and validate sustainable HCAI definitions in Africa to support the implementation of routine HCAI surveillance and inform implementation of context appropriate infection prevention and control strategies.

Antimicrobial approach of abdominal post-surgical infections

Abdominal surgical site infections (SSIs) are infections that occur after abdominal surgery. They can be superficial, involving the skin tissue only, or more profound, involving deeper skin tissues including organs and implanted materials. Currently, SSIs are large global health problem with an incidence that varies significantly depending on the United Nations' Human Development Index. The purpose of this review is to provide a practical update on the latest available literature on SSIs, focusing on causative pathogens and treatment with an overview of the ongoing studies of new therapeutic strategies.

Epidemiological manifestations and impact of healthcare-associated infections in Libyan national hospitals

BACKGROUND

Healthcare-associated infection is a serious global problem, particularly in developing countries. In North African countries, comprehensive research on the incidence and effects of such infections is rare. This study evaluated the epidemiology and determined the impact of healthcare-associated infections in Libyan national teaching hospitals.

METHODS

A prospective longitudinal study was carried out in Libya's four largest teaching and referral hospitals (Tripoli Medical Center, Tripoli-Central Hospital, Benghazi Medical Center, and Sabha Medical Center) from November 1, 2021, to October 31, 2022. The epidemiological events and the parameters incorporated in this study were based on the data published by the Libyan Centers for Disease Control. The surveillance was carried out on all patients admitted to the wards of medicine, surgery, intensive care, gynecology & obstetrics, and pediatrics in all four hospitals. Trained staff reviewed the medical records and compared the percentages of patients with healthcare-associated infections. Bio-statistical and multivariable logistic regression analyses were carried out to test the variables associated with healthcare-associated infections and the resulting deaths.

RESULTS

A total of 22,170 hospitalized patients in four hospitals were included in the study. Hospital-acquired infection was reported in 3037 patients (13.7%; 95% CI: 12.9-14.4%). The highest incidence was in Benghazi Medical Center (17.9%; 95% CI: 16.9-18.7%), followed by Sabha Medical Center (14.8%; 95% CI:14.9-16.51%). Surgical site infection was the most prevalent (31.3%), followed by ventilator-associated pneumonia (29.3%), urinary tract infection (26.8%), and bloodstream infection (12.6%). Patients with healthcare-associated infections experienced severe morbidity requiring intervention. New antimicrobial regimens were needed for 1836 patients (93%), and 752 patients (34%) required admission to intensive care. Surgical intervention, respiratory support, and inotropes were also needed as a consequence of HAI events.

CONCLUSIONS

The high incidence of healthcare-associated infections in Libyan hospitals should be considered a major problem and a serious burden. This should alert healthcare authorities at the national and hospital levels to the urgent need for preventive and control strategies to combat hospital-acquired infections.

The effect of high perioperative inspiratory oxygen fraction for abdominal surgery on surgical site infection: a systematic review and meta-analysis

Guidelines from the World Health Organization strongly recommend the use of a high fraction of inspired oxygen (FiO2) in adult patients undergoing general anesthesia to reduce surgical site infection (SSI). However, previous meta-analyses reported inconsistent results. We aimed to address this controversy by focusing specifically on abdominal surgery with relatively high risk of SSI. Medline, EMBASE, and Cochrane CENTRAL databases were searched. Randomized trials of abdominal surgery comparing high to low perioperative FiO2 were included, given that the incidence of SSI was reported as an outcome. Meta-analyses of risk ratios (RR) were performed using a fixed effects model. Subgroup analysis and meta-regression were employed to explore sources of heterogeneity. We included 27 trials involving 15977 patients. The use of high FiO2 significantly reduced the incidence of SSI (n = 27, risk ratio (RR): 0.87; 95% confidence interval (CI): 0.79, 0.95; I2 = 49%, Z = 3.05). Trial sequential analysis (TSA) revealed that z-curve crossed the trial sequential boundary and data are sufficient. This finding held true for the subgroup of emergency operations (n = 2, RR: 0.54; 95% CI: 0.35, 0.84; I2 = 0%, Z = 2.75), procedures using air as carrier gas (n = 9, RR: 0.79; 95% CI: 0.69, 0.91; I2 = 60%, Z = 3.26), and when a high level of FiO2 was maintained for a postoperative 6 h or more (n = 9, RR: 0.68; 95% CI: 0.56, 0.83; I2 = 46%, Z = 3.83). Meta-regression revealed no significant interaction between SSI with any covariates including age, sex, body-mass index, diabetes mellitus, duration of surgery, and smoking. Quality of evidence was assessed to be moderate to very low. Our pooled analysis revealed that the application of high FiO2 reduced the incidence of SSI after abdominal operations. Although TSA demonstrated sufficient data and cumulative analysis crossed the TSA boundary, our results should be interpreted cautiously given the low quality of evidence.Registration: https://www.crd.york.ac.uk/prospero (CRD42022369212) on October 2022.

Surgical site infection and antimicrobial prophylaxis prescribing profile, and its determinants among hospitalized patients in Northeast Ethiopia: a hospital based cross-sectional study

The inappropriate use of surgical antimicrobial prophylaxis is a common cause for increased risk of morbidity and mortality from surgical site infection in patients who underwent surgical procedures. The study aimed to evaluate surgical antimicrobial prophylaxis prescribing patterns, Surgical Site Infection (SSI), and its determinants in the surgical ward of Debre Berhan Comprehensive Specialized Hospital, northeast Ethiopia. A prospective cross-sectional study was conducted from October 1st 2022 to January 31st, 2023. Data collected from patient medical record cards and patient interviews were entered and analyzed using SPSS V26.0. The determinants of surgical site infection were determined from the multivariable logistic regression. P-value ≤ 0.05 was considered statistically significant. Ceftriaxone (70.5%) followed by a combination of ceftriaxone with metronidazole (21.90%) was the most frequently used prophylactic antibiotic. One hundred fifty-nine (78%) of patients were exposed to inappropriately used prophylactic antimicrobials and 62.2% of these were exposed to inappropriately selected antibiotics. One hundred twenty-six (61.9%) patients developed Surgical Site Infection (SSI). Duration of procedure longer than an hour and inappropriate use of antimicrobial prophylaxiswere the independent predictors for the occurrence of surgical site infections. Patients whose operation was lasted in longer than an hour were 3.39 times more likely to develop SSI compared to those whose operation was completed in less than an hour, AOR = 3.39 (95% CI: 1.24-9.30). Similarly, controlling the effect of other covariate variables, individuals who were given inappropriate antimicrobial prophylaxis were 6.67 times more likely to develop SSI compared to those given appropriate prophylaxis, AOR = 6.67 (95% CI: 1.05-42.49). The high rate of SSI requires due attention from clinicians as well as health policymakers. Duration of surgical procedure greater than an hour and inappropriate antimicrobial prophylaxis use was the independent predictor of surgical site infections.

Maternal complications and associated factors among mothers who underwent a cesarean section at Gebretsadik Shewa general hospital: an institution based cross-sectional study

Introduction

Cesarean sections have played a major role in lowering maternal morbidity and mortality rates, but are a major concern in developing countries. This study aims to assess the magnitude of maternal complication and its associated factors among women who underwent a cesarean section at Gebretsadik Shewa general hospital, Southwest Ethiopia.

Method

A hospital-based cross-sectional study was conducted in Gebretsadik Shewa general hospital. Data were extracted from 382 mothers' medical charts, retrieved from the labor and operations theatre log book registry using systematic random sampling technique. The extracted data was coded and entered into Epi Data version 3.0, and exported to Statistical Package for Social Sciences (SPSS) version 20 for analysis. Logistic regression analysis was conducted and significance and strength association was determined considering AOR with a 95% confidence level.

Result

A total of 382 mothers' charts were reviewed; however, 368 charts were eligible for data entry. The age of the participants ranges between 16 and 42 years with mean and standard deviation of 26.1 ± 4.8 years. Maternal complication rate was 30.4% [95% CI: 25.8- 35.1]. Surgical site infection (10.3%), anemia (6.5%) and intraoperative bleeding (4.6%) were the most common. Multivariable logistic regression analysis showed that no antenatal care follow up, medical illness during pregnancy, emergency cesarean section and not receiving a prophylactic antibiotic were statistically associated with maternal complications.

Conclusion

The incidence of maternal complication following cesarean delivery was unduly high. Community based education about antenatal care follow up and its importance should be further strengthened for favorable maternal and fetal outcomes.

Assessment of risk factors associated with surgical site infection following abdominal surgery: a systematic review

Objective

Surgical site infections (SSIs) are among the most common healthcare-associated infections occurring following 1%-3% of all surgical procedures. Their rates are the highest following abdominal surgery. They are still associated with increased morbidity and healthcare costs despite the advancement in the medical field. Many risk factors for SSIs following abdominal surgery have been identified. The aim of this study is to comprehensively assess these risk factors as published in peer-reviewed journals.

Design

A systematic review was conducted with accordance to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.

Setting

The databases for search were PubMed and Cochrane Library, in addition to reference lists. Studies were retrieved and assessed for their quality. Data were extracted in a designed form, and a stratified synthesis of data was conducted to report the significant risk factors.

Participants

Patients undergoing general abdominal surgery.

Intervention

The intervention of general abdominal surgery.

Main outcome measures

To identify and assess the risk factors for SSI following abdominal surgery.

Results

Literature search yielded 813 articles, and the final screening process identified 11 eligible studies. The total number of patients is 11 996. The rates of SSI ranged from 4.09% to 26.7%. Nine studies were assessed to be of high quality, the remaining two studies have moderate quality. Stratified synthesis of data was performed for risk factors using summary measures (OR/risk ratio, 95% CI, and p value). Male sex and increased body mass index (BMI) were identified as significant demographic risk factors, and long operative time was among the major significant procedure-related risk factors.

Conclusions

Male sex, increased BMI, diabetes, smoking, American Society of Anesthesiologists classification of >2, low albumin level, low haemoglobin level, preoperative hospital stay, long operative time, emergency procedure, open surgical approach, increased wound class, intraoperative blood loss, perioperative infection, perioperative blood transfusion, and use of drains are potential independent risk factors for SSI following abdominal surgery.

Time to development of surgical site infection and its predictors among general surgery patients admitted at specialized hospitals in Amhara region, northwest Ethiopia: a prospective follow-up study

BACKGROUND

Surgical site infection is an infection occurring within 30 days after surgery. It is recently reported that evidence-based information on the specific time when the majority of surgical site infections would develop is a key to early detect the infection as well as to preventing and early intervene against their pressing and fatal complications. Therefore, the current study aimed to determine the incidence, predictors, and time to development of surgical site infection among general surgery patients at specialized hospitals in the Amhara region.

METHOD

An institution-based prospective follow-up study was conducted. The two-stage cluster sampling procedure was used. A systematic sampling technique with a K interval of 2 was applied to prospectively recruit 454 surgical patients. Patients were followed up for 30 days. Data were collected using Epicollect5 v 3.0.5 software. Post-discharge follow-up and diagnosis were done by telephone call follow-up. Data were analyzed using STATA™ version 14.0. Kaplan-Meier curve was used to estimate survival time. Cox proportional regression model was used to determine significant predictors. Variables with a P-value less than 0.05 in the multiple Cox regression models were independent predictors.

RESULT

The incidence density was 17.59 per 1000 person-day-observation. The incidence of post-discharge Surgical site infection was 70.3%. The majority of surgical site infections were discovered after discharge between postoperative days 9 to 16. Being male (AHR: 1.98, 95% CI: 1.201 - 3.277, diabetes Mellitus (AHR: 1.819, 95% CI: 1.097 - 3.016), surgical history (AHR: 2.078, 95% CI: 1.345, 3.211), early antimicrobial prophylaxis (AHR: 2.60, 95% CI: 1.676, 4.039), American Society of Anesthesiologists score ≥ III AHR: 6.710, 95% CI: 4.108, 10.960), duration of the surgery (AHR: 1.035 95% CI: 1.001, 1.070), Age (AHR: 1.022 95% CI: 1.000, 1.043), and the number of professionals in the Operation Room (AHR: 1.085 95% CI: 1.037, 1.134) were found to be the predictors of time to development of Surgical site infection.

CONCLUSION

The incidence of surgical site infection was higher than the acceptable international range. The majority of infections were detected after hospital discharge between 9 to 16 postoperative days. The main predictors of Surgical site infection were Age, Sex, Diabetes Mellitus, previous surgical history, the timing of Antimicrobial prophylaxis, American Society of Anesthesiologists score, pre-operative hospital stay, duration of surgery, and the number of professionals in the operation room. Hence, hospitals should give great emphasis on pre-operative preparation, post-discharge surveillance, modifiable predictors, and high-risk patients, as they found in this study.

Incidence of surgical site infection, bacterial isolate, and their antimicrobial susceptibility pattern among patients who underwent surgery at Dessie Comprehensive Specialized Hospital, Northeast Ethiopia

Objective

Surgical site infection is the most common postoperative complication worldwide, representing a major burden for patients and health systems. The aim of the study is to determine the incidence and bacterial profile that cause surgical site infection among patients who underwent surgery in parts of Northeast Ethiopia.

Methods

A health facility-based cross-sectional study was conducted in Dessie Comprehensive Specialized Hospital from July 22 to October 25, 2016. A total of 338 patients from the obstetrics and gynecology and general surgical wards were included, through consecutive sampling technique. The specimens were collected aseptically on the first day when the patients had presented with clinical evidence of infection and then sent to the microbiology laboratory. The data were entered and analyzed by SPSS version 20, and the results were explained by frequency distribution in tables and figures.

Results

The majority of participants were female (74.3%) and more than half (61.2%) of the surgeries were performed in the gynecology and obstetrics ward. Clinically, 49 patients (14.5%) were diagnosed as developing surgical site infection, and wound swabs were taken for bacteriological study. About 41 (83.7%) swabs showed bacterial growth, indicating 12.13% overall prevalence of bacterial surgical site infection. Out of 48 bacterial isolates, more than half (56.25%) of them were Gram negative. The most frequent isolate was Staphylococcus aureus, 14 (66.67%), followed by Escherichia coli, 9 (33.33%). Out of the total bacterial isolates, 38 (79.2%) isolates were found to be multidrug resistant, and the rate of multidrug resistant was higher among Gram-negative isolates.

Conclusion

An average rate of surgical site infection was found to be reported and significant numbers of bacterial isolates were also detected. The highest rate of surgical site infection was reported in prostate surgery, followed by small bowel, vaginal hysterectomy, and exploratory laparotomy surgical procedures. Periodic surveillance on the incidence rate and bacterial profile along with the determination of their antibiotic susceptibility should be performed.

Surgical Site Infections at Shirati KMT Hospital in Northeastern Tanzania

Despite improved guidelines for surgical practices and better surgical methods and tools, surgical site infection (SSI) is still a common cause of morbidity and mortality with increased rates in resource-limited nations. In Tanzania, there is limited data on SSI and associated risk factors for developing an effective surveillance system for SSI. In this study, we aimed to establish for the first time the baseline SSI rate and its associated factors at the Shirati KMT Hospital in Northeastern Tanzania. We collected hospital records of 423 patients who had undergone major and minor surgeries between January 1 and June 9, 2019, at the hospital. After accounting for incomplete records and missing information, we analyzed a total of 128 patients and found an SSI rate of 10.9% and performed univariate and multivariate logistic regression analyses for elucidating the relationship between risk factors and SSI. All patients with SSI had undergone major operations. Moreover, we observed trends of increased association of SSI with patients who are 40 or younger, female, and had received antimicrobial prophylaxis or more than one type of antibiotics. In addition, patients who had received an American Society of Anesthesiologists (ASA) score of II or III, as one category, or undergone elective operations or operations lasting longer than 30 minutes were prone to develop SSI. Although these findings were not statistically significant, both univariate and multivariate logistic regression analyses showed a significant correlation between clean contaminated wound class and SSI, consistent with previous reports. The study is the first to elucidate the rate of SSI and its correlated risk factors at the Shirati KMT Hospital. We conclude that, based on the obtained data, clean contaminated wound class is a significant predictor of SSI at the hospital and that an effective surveillance system for SSI should begin with adequate record keeping of all patients' hospitalization and an efficient follow-up system. Moreover, a future study should aim to explore more widespread SSI predictors such as premorbid illness, HIV status, duration of hospitalization prior to operation, and type of surgery.

Magnitude of surgical site infection and determinant factors among postoperative patients, A cross sectional study

Background

Surgical site infections (SSIs) are infections that occur within 30 days of surgery or within 1 year in patients with implants at or around the surgical site. They are among the dangerous complications of surgical procedures that expose patients to higher costs and increase the risk of death because of severe morbidity and associated longer hospital stays. This study aimed to determine the extent and determinants of surgical site infections in surgically treated cases during the study period.

Methods

A hospital-based cross-sectional study was conducted among surgically treated patients at Dilla University Referral Hospital in the surgical department. The calculated sample size was 408, calculated using the single population proportion formula, and the required information was collected from the medical records of the study participants using checklists. Bivariate logistic regression was performed to identify candidate variables, and all candidate variables with a P-value < of 0.25 were included in multivariable logistic regression. Variables with a P-value < 0.05 were considered statically significant, and the strength of association was measured by odds ratio (OR) with 95% confidence intervals (CIs).

Result

As our finding showed magnitude of surgical site infections was 19.3%. The factors which had significant association with surgical wound infections were blood transfusion (AOR = 0.16 (0.04–0.73), hemoglobin level < 7 g/dl (AOR = 10.40 (3.39–32.49), shock (AOR = 19.09 (4.69–77.51), previous surgery (AOR = 11.53(3.73–35.61), hospitalization 7–14 days (AOR = 5.51(1.52–19.91) and hospitalization >14 days (AOR = 8.18(1.84–36.75).

Conclusion

The percentage of surgical site infections was high. Shock, low haemoglobin level, blood transfusion, previous surgery, and longer length of hospital stay were significantly related to surgical site infections.

•

Magnitude of Surgical site infection was high.

•

Low haemoglobin level has significant association with occurrence of surgical site infection.

•

Longer hospital stay has association with development of surgical site infection.

Assessment of Bacterial Profiles and Antimicrobial Susceptibility Pattern of Isolates Among Patients Diagnosed with Surgical Site Infections at Mizan-Tepi University Teaching Hospital, Southwest Ethiopia: A Prospective Observational Cohort Study

Background

Although emergency health-care services, particularly clinical and surgical care, are an important part of the provision of high quality health care in Ethiopia, infections related with surgical care are still the most well-known medical services-related diseases. This study aimed to assess the bacterial profiles and antimicrobial susceptibility pattern of isolates among patients diagnosed with surgical site infections at Mizan-Tepi university teaching hospital, southwest Ethiopia.

Methodology

A prospective observational cohort study was conducted from June to September 2021. Patient data were collected using a structured questionnaire. Follow-up of patients who had undergone a surgical procedure was conducted for at least 30 days. Wound swabs were collected from patients suspected to have surgical site infections (SSIs) and cultured onto appropriate culture media. The antimicrobial susceptibility testing was done using the disk diffusion technique. Data were analyzed using SPSS software version 25.0. Frequencies and cross-tabulation were used to summarize descriptive statistics.

Results

In this study, the postoperative SSIs rate was 12.6%. All patients with SSIs were culture positive, and a total of 41 bacterial isolates were detected. Of these, 73.2% were Gram-negative, 26.8% were Gram-positive and 24.2% were a mixture of two bacterial growths. Escherichia coli accounted for 29.3%, followed by Staphylococcus aureus (19.5%), Proteus species (14.6%) and Pseudomonas aeruginosa (12.2%). With the exceptions of amikacin and meropenem, which exhibited very high sensitivity, ranging from 33.3–100.0% isolates was resistant against all other tested antibiotics. The resistance rate to three or more classes of antibiotics was 100.0%.

Conclusion

In this study, the most isolated bacteria causing SSIs were Gram-negative and multidrug-resistant strains. This event highlights that surveillance of the bacterial profile and antibiotic susceptibility pattern coupled with the implementation of the strict protocol for antibiotic use and operative room regulations is important to minimize the burden of SSIs.

Length of preoperative hospital stay is the dominating risk factor for surgical site infection in neurosurgery: A cohort data-driven analysis

Background

The number of days of preoperative hospital stay (PHS) is a modifiable variable that has shown contradictory surgical site infection (SSI) risk factor results in neurosurgery. We sought to pinpoint the day of PHS length related with a marked increase of risk of SSI.

Methods

From a tertiary teaching hospital, January 2015-December 2017, prospectively collected nonpercutaneous neurosurgery procedures with standard antibiotic prophylaxis and 1-year follow-up were evaluated. SSI risk factors were assessed through multiple logistic regression models with different thresholds of PHS.

Results

A total of 1012 procedures were included in the study. Incidence of SSI was 4.4%. The median PHS was higher in those with SSI than in those without (1 day, interquartile range [IQR]: 7 vs. 0 days, IQR: 1, respectively, P = 0.002). By the amount of six days of PHS, this exposure risk past the threshold of significance for impact on wound infection (OR 2.8; CI 1.23-6.39, P = 0.014). Operative time past 4 h (OR 2.11; CI 1.12-3.98; P = 0.021), and in some models, previous surgery at same admission were also identified by multivariate analysis as increasing postoperative SSI risk.

Conclusion

The gradual increase of the SSI OR associated with longer PHS days was the highest risk factor of SSI in our cohort of patients. Studies directed to reduce this complication should consider the PHS.

Antimicrobial Prophylaxis Reduces the Rate of Surgical Site Infection in Upper Gastrointestinal Surgery: A Systematic Review

Surgical site infection occurs with high frequency in gastrointestinal surgery, contributing to the high incidence of morbidity and mortality. The accepted practice worldwide for the prevention of surgical site infection is providing single- or multiple-dose antimicrobial prophylaxis. However, most suitable antibiotic and optimal duration of prophylaxis are still debated. The aim of the systematic review is to assess the efficacy of antimicrobial prophylaxis in controlling surgical site infection rate following esophagogastric surgery. PubMed and Cochrane databases were systematically searched until 31 October 2021, for randomized controlled trials comparing different antimicrobial regimens in prevention surgical site infections. Risk of bias of studies was assessed with standard methods. Overall, eight studies concerning gastric surgery and one study about esophageal surgery met inclusion criteria. No significant differences were detected between single- and multiple-dose antibiotic prophylaxis. Most trials assessed the performance of cephalosporins or inhibitor of bacterial beta-lactamase. Antimicrobial prophylaxis (AMP) is effective in reducing the incidence of surgical site infection. Multiple-dose antimicrobial prophylaxis is not recommended for patients undergoing gastric surgery. Further randomized controlled trials are needed to determine the efficacy and safety of antimicrobial prophylaxis in esophageal cancer patients.

The burden of surgical site infections and related antibiotic resistance in two geographic regions of Sierra Leone: a prospective study

Despite the prolongation of hospitalization, increase in morbidity, mortality and cost of care associated with both surgical site infections (SSIs) and antibiotic resistance, there are limited data on SSIs and antibiotic resistance to guide prevention strategies in Sierra Leone. This study assessed the burden of SSIs and related antibiotic resistance in the 34 Military Hospital (MH) and Makeni Government Hospital (MGH) located in two geographic regions of Sierra Leone using a prospective study design to collect data from adults aged 18 years or older. Of the 417 patients, 233 (55.9%) were enrolled in MGH. Most were women 294 (70.5%). The incidence rate of SSI was 5.5 per 1000 patient-days, and the cumulative incidence of SSI was 8.2%. Common bacteria isolated in MH were Escherichia coli (6,33.3%) and Pseudomonas aeruginosa (3,16.7%) and in MGH were P. aeruginosa (3,42.9%) and Proteus mirabilis (2,28.9%). Of the gram-negative bacteria, 40% were Extended-spectrum beta-lactamase-producing Enterobacteriaceae, 33% were Carbapenem-resistant P. aeruginosa and 10% were carbapenem-resistant Enterobacteriaceae. Although the incidence of SSIs in our study is lower than previously reported, the rate of antibiotic resistance reported in this study is high. Urgent action is needed to invest in the microbiology infrastructure to support SSI surveillance and prevention strategies.

OUP accepted manuscript

Background

Surgical site infection (SSI) is a common complication after abdominal surgery. The effectiveness of wound edge protectors in reducing infection of the surgical sites is still unclear. The purpose of this study was to determine the clinical effectiveness of a wound edge protector (WEP) in reducing SSI rates after abdominal surgery.

Methods

PubMed, Embase, Web of Science, and the Cochrane Library were systematically searched to obtain relevant articles published up to September 2021. Publications were retrieved if they contain primary data on the use of WEPs in reducing SSI compared with standard care in patients undergoing abdominal surgery. Subgroup analyses were performed for different WEP types, surgical sites, and levels of contamination. The outcome of interest was a clinically defined SSI. Qualitative variables were pooled using risk ratios (RRs).

Results

Twenty-two eligible randomized clinical trials involving 4492 patients were included in this meta-analysis. WEP was associated with the reduced incidence of overall SSI (RR = 0.66; 95 per cent c.i. 0.53 to 0.83; P = 0.0003), and superficial SSI (RR = 0.59; 95 per cent c.i. 0.38 to 0.91; P = 0.02). In addition, WEP also successfully reduced the risk of SSI in clean-contaminated wounds (RR = 0.61; 95 per cent c.i. 0.40 to 0.93; P = 0.02) as well as in contaminated wounds (RR = 0.47; 95 per cent c.i. 0.33 to 0.67; P < 0.0001); however, WEP did not reduce SSI incidence in colorectal surgery (RR = 0.68; 95 per cent c.i. 0.46 to 1.01; P = 0.05).

Conclusion

This study suggests that WEP was efficient in reducing superficial SSI. Both double-ringed and single-ringed devices were efficient in reducing SSI. WEP was effective in reducing SSI incidence in clean-contaminated and contaminated surgery; however, its use does not reduce the SSI rate in colorectal surgery.

Risk Stratification for Organ/Space Surgical Site Infection in Advanced Digestive System Cancer

Background

Organ/space surgical site infection (organ/space SSI) is a serious postoperative complication, closely related to a poor prognosis. Few studies have attempted to stratify the risk of organ/space SSI for patients with advanced digestive system cancer. This study aimed to identify a simple risk stratification for these patients based on perioperative factors.

Methods

The study was based on two randomized controlled trials (RCT) (NCT02715076, ChiCTR-IPR-17011099), including 839 patients undergoing elective radical resection of advanced digestive system cancer. The primary outcome was organ/space SSI within 30 days after surgery. Multivariable logistic regression model was used to identify risk factors. The risk of organ/space SSI stratified over those risk factors was compared using chi-square tests and the relative risk (RR) was estimated.

Results

Among the 839 patients, 51 developed organ/space SSI (6.1%) within 30 days after surgery. According to the multivariable logistic regression model, 3 procedure types, including gastrectomy (OR=8.22, 95% CI: 2.71-24.87, P<0.001), colorectal resection (OR=8.65, 95% CI: 3.13-23.85, P<0.001) and pancreatoduodenectomy (OR=7.72, 95% CI: 2.95-20.21, P<0.001), as well as anaesthesia time > 4 h (OR=2.38, 95% CI: 1.08-5.27, P=0.032) and prolonged ICU stay (OR=4.10, 95% CI: 1.67-10.10, P=0.002), were risk factors for postoperative organ/space SSI. The number of risk factors was significantly associated with an increased risk of organ/space SSI (P<0.001), which was 2.8% in patients with 0-1 risk factor (RR=0.20, 95% CI: 0.11-0.35), 13.0% in patients with 2 risk factors (RR=3.64, 95% CI: 2.14-6.20) and 35.7% in patients with 3 risk factors (RR=6.41, 95% CI: 3.01-13.65).

Conclusion

This study is a preliminary exploratory and provides a simple risk stratification to identify the risk of postoperative organ/space SSI for patients with advanced digestive system cancer. Further research is needed to validate and generalize the results in a wider population.

Is Single-Dose Antimicrobial Prophylaxis Sufficient to Control Infections in Gastrointestinal Oncological Surgeries?

Surgical site infections (SSIs) represent one of the most important complications occurring postoperatively following surgical procedures. The SSI incidence is higher following gastrointestinal (GI) surgeries compared to any other surgery. It contributes to the majority of morbidity and mortality in patients undergoing GI surgeries. The accepted practice worldwide for the prevention and control of SSIs is providing antimicrobial prophylaxis. The appropriate antimicrobial and dose are chosen depending on the microbial flora, complications, and patient risk factors. The objective of this review was to determine the sufficient number of prophylactic antimicrobial doses that would be efficacious and safe in controlling the SSIs following GI oncological surgeries. Single-dose antimicrobial prophylaxis has shown the same efficacy as the multiple-dose antimicrobial regimen in controlling SSIs in esophageal, gastric, and colorectal surgeries. The advantages of a single-dose regimen include less chance of emergence of resistance, less chance for allergies or toxicity, and less cost. The addition of metronidazole with single-dose antimicrobial prophylaxis in colorectal surgery should be considered due to its beneficial effect in further reducing infections. Further randomized controlled trials are needed for the literature to determine the efficacy and safety of single-dose antimicrobial prophylaxis in patients undergoing esophageal and colorectal surgeries. In addition, studies are required to determine the individual effectiveness of metronidazole in controlling SSIs in colorectal surgeries.

Evaluation of Wound Healing Activity of Methanolic Crude Extract and Solvent Fractions of the Leaves of Vernonia auriculifera Hiern (Asteraceae) in Mice

Background

Medicinal plants play an important role in treating various diseases. Vernonia auriculifera Hiern is one of the medicinal plants used traditionally for the management of wounds. However, there were no scientific reports documented so far on the wound healing activities to substantiate the claim. Thus, the present study provides a scientific evaluation for the wound healing potential of the crude extract as well as solvent fractions of the leaves of Vernonia auriculifera Hiern.

Methods

Extraction was carried out by maceration using 80% methanol and part of the crude extract fractionated with chloroform, ethyl acetate, and aqueous solvents. Simple ointment bases were prepared using hard paraffin, cetostearyl alcohol, white soft paraffin and wool fat according to British Pharmacopoeia. Then, two types of ointment formulations were prepared from the extract, ie, 5% w/w and 10% w/w. Mice and rats were employed for wound healing study and dermal toxicity test, respectively. Wound healing effects were evaluated by percent of wound contraction, period of epithelialization, tensile strength, and histological analysis as parameters in excision, incision, and burn wound models. Finally, the data were expressed as mean ± SEM, and the results were analyzed using one-way ANOVA followed by post hoc Tukey-test.

Results

In the excision wound model, the 10% w/w crude extract ointment showed significant wound contraction (P < 0.001) from day 4 to day 18 as compared to the negative control. Both the 5% w/w (P < 0.001) and 10% w/w (P < 0.05) crude extract ointments have showed statistically significant difference in epithelialization period as compared to the negative control. Groups treated with the ethyl acetate and aqueous fractions ointments in incision wound model showed a statistically significant (P < 0.001) increase in tensile. The 10% w/w and 5% w/w ointments of the crude extract showed a significant (P < 0.001) increase in breaking strength compared to simple ointment and the untreated control groups. In burn wound model, significant reduction in epithelialization period was observed in 5% w/w (P < 0.05) and 10% w/w (P < 0.001), and the percentage of wound contraction was significantly increased in most of post wounding days by 10% w/w (P < 0.001) and 5% w/w (P < 0.05) crude extract ointments and compared to the negative control.

Conclusion

The crude, aqueous, and ethyl acetate fraction of Vernonia auriculifera leaves possess wound healing activities. This finding justifies the use of the leaves of this plant for wound healing as claimed in the traditional medicine literature.

Adverse maternal outcomes associated with Cesarean deliveries and their determinants: hospital based cross sectional, mixed- methods study

Purpose

The purpose of this study was to examine adverse outcomes associated with cesarean deliveries and to assess potential confounding factors.

Design/methodology/approach

A hospital-based cross-sectional study was conducted from September 1−30, 2019 using mixed methods of data collection. Multistage sampling was used to draw the eligible study participants. The sample size was calculated using the single population proportion formula. A systematic random sampling technique was used to draw the sample size. 180 original medical records were excluded because of having missed information, leaving 1,618 women as the study population. We used the questionnaire adapted from the Ethiopian Demographic and Health Survey to collect quantitative data and analyzed using SPSS version 22, while thematic analysis for qualitative measures was used to generate themes regarding associated perspectives of participants from a community.

Findings

More than 383 women delivered by cesarean section. 20% of the mothers with the mean age at birth of 26.1 ± 4.8 experienced adverse outcomes. Adjusted odds ratio (AOR) was used to measure the association of determinants and was 2.95 (95% CI 1.19–7.29) for nonuse of antenatal care, 3.18 (95% CI 1.43–6.94) for nonuse of prophylaxis, 4.28 (95% CI 1.58−11.61) for history of medical illness and 7.09 (95% CI 1.19−45.59) for use of substandard operation set up compared with their counterparts.

Research limitations/implications

Strengths of the study include the finding of the study are reliably reported in mixed study methods examining hospital-based institutional and personal risk factors and exploring the whole community's perspectives. However, the important limitations of the study indicate that the study poses a number of challenges related to studying design, therefore there was not sufficient evidence of causality to draw conclusions from the findings. In addition, the study was conducted at a single hospital so that it is not convenient to generalize the findings of the study for setting different in social and economic status.

Originality/value

Based on the findings, attention has been drawn to healthcare personnel to provide training and consultation services for pregnant women and for health care administration to ensure standard set up for operation.

Risk factors for surgical site infection after major oral oncological surgery: the experience of a tertiary referral hospital in China

Objective

To identify risk factors associated with surgical site infection (SSI) after major oral oncological surgery.

Methods

This retrospective study reviewed data from patients that underwent major surgery for oral cancer at a tertiary referral hospital in China between January 2005 and July 2016. SSI was diagnosed within 30 days. Demographic, cancer-related, preoperative, perioperative and postoperative data were analysed using descriptive statistics and univariate and multivariate analyses of the risk factors for SSI.

Results

A total of 786 patients were enrolled, of whom 125 had SSI (15.9%), which were all incisional. Independent risk factors for SSI, identified by multivariate analysis, were diabetes mellitus (odds ratio [OR] 2.147, 95% confidence interval [CI] 1.240, 3.642), prior radiotherapy (OR 4.595, 95% CI 1.293, 17.317) and oral–neck communication (OR 2.838, 95% CI 1.263, 7.604); and factors reflecting large extent resections were tracheostomy (OR 2.235, 95% CI 1.435, 3.525), anterolateral thigh flap (OR 1.971, 95% CI 1.103, 3.448) and latissimus dorsi flap (OR 4.178, 95% CI 1.325, 13.189).

Conclusions

Multiple risk factors were associated with SSI after major oral oncological surgery. To minimize SSI risk, surgeons managing oral cancer patients should have a better understanding of the risk factors, including diabetes mellitus, prior radiotherapy, tracheostomy, oral–neck communication and flap reconstruction.

Bacterial profile and antimicrobial susceptibility patterns of isolates among patients diagnosed with surgical site infection at a tertiary teaching hospital in Ethiopia: a prospective cohort study

BACKGROUND

Globally, surgical site infections are the most reported healthcare-associated infection and common surgical complication. In developing countries such as Ethiopia, there is a paucity of published reports on the microbiologic profile and resistance patterns of an isolates.

OBJECTIVE

This study aimed at assessing the bacterial profile and antimicrobial susceptibility patterns of isolates among patients diagnosed with surgical site infection at Jimma Medical Center in Ethiopia.

METHODS

A prospective cohort study was employed among adult patients who underwent either elective or emergency surgical procedures. All the eligible patients were followed for 30 days for the occurrence of surgical site infection (SSI). From those who developed SSI, infected wound specimens were collected and studied bacteriologically.

RESULTS

Of 251 study participants, 126 (50.2%) of them were females. The mean ± SD age of the patients was 38 ± 16.30 years. The overall postoperative surgical site infection rate was 21.1% and of these 71.7% (38/53) were culture positive. On gram stain analysis, 78% of them were Gram-negative, 11.5% were Gram-positive and 10.5% were a mixture of two microbial growths. Escherichia coli accounted for (21.43%), followed by Pseudomonas aeruginosa (19.05%), Proteus species (spp.) 14.29%), Staphylococcus aureus (11.90%), Klebsiella species (11.90%), Citrobacter spp. (9.5%), streptococcal spp. (7.14%), Coagulase-negative S. aureus (CoNS) (2.38%) CONCLUSION: Gram-negative bacteria were the most dominant isolates from surgical sites in the study area. Among the Gram-negative bacilli, Escherichia coli were the most common bacteria causing surgical site infection. As there is high antibiotic resistance observed in the current study, it is necessary for routine microbial analysis of samples and their antibiogram.

Incidence, risk factors and outcomes of surgical site infections among patients admitted to Jimma Medical Center, South West Ethiopia: Prospective cohort study

Background

Surgical site infections are one of the leading health care–associated infections in developing countries. Despite improvements in surgical technique and the use of best infection prevention strategies, surgical site infections remained the major cause of hospital acquired infections. Therefore, this study aimed to determine incidence, risk factors, and outcomes of surgical site infections among patients admitted to Jimma Medical Center, South West Ethiopia.

Methods

A hospital based prospective cohort study design was employed to follow adult patients admitted to general surgery ward, orthopaedic ward and gynaecologic/obstetrics ward of Jimma Medical Centre, from April 20 to August 20, 2019. All patients were followed daily before, during and after operation for 30 days to determine the incidence of surgical site infection and other outcomes. Data was entered using EpiData version 4.2 and analyzed using statistical software package for social science version 20.0. To identify the independent predictors of outcome, multiple stepwise backward cox regression analysis was done. Statistical significance was considered at p-value <0.05.

Results

Of total of 251 participants included to the study, about 126 (50.2%) of them were females. The mean ± SD age of patients was 38 ± 16.30 years. Considerable number of patients 53(21.1%) developed surgical site infections. American Society of Anaesthesiologists score ≥3 [ Adjusted Hazard Ratio (AHR) = 2.26; 95%CI = (1.03–4.93)], postoperative antibiotic prescription [AHR = 3.2; 95%CI = (1.71–6.01)], contaminated-wound [AHR = 7.9; 95%CI = (4.3–14.60)], emergency surgery [AHR = 2.8; 95% CI = (1.16–6.80)], duration of operation ≥ 2 h [AHR = 4; 95% CI = (2.17–7.50)] and comorbidity [AHR = 2.52; 95%CI = (1.28–4.94)] were independent predictors for surgical site infections. Twenty nine (11.6%) patients returned to operation room. The result of the multivariate cox regression analysis showed that SSI [AHR (95% CI) = 7(3.16–15.72)], and incision site [AHR (95% CI) = 2.5(1.14–5.42)] had statistically significant association with re-operation

Conclusion

The incidence of surgical site infection was high in the study setting. There were significant numbers of contributing factors for the occurrence of surgical site infections. Although no mortality observed during the study period, significant number of patients re-operated. Large multicenter study is urgently needed to confirm the outcome of this study.

•

Surgical site infections are one of the leading health care–associated infections in developing countries.

•

Considerable number of risk factors are associated with the occurrence of surgical site infection.

•

Surgical site infection is associated with increased length of hospital stay and number of patients re-operated.

A retrospective analysis of factors affecting surgical site infection in orthopaedic patients

Objective

To investigate the factors affecting surgical site infections (SSI) in patients undergoing orthopaedic surgery.

Methods

The electronic medical records of patients undergoing orthopaedic surgery between September 2010 and July 2018 were retrospectively retrieved and reviewed. Logistic regression analyses were used to analyse the correlation between surgery-related variables and SSI. The odds ratio (OR) and 95% confidence interval (CI) were estimated for the risk factors.

Results

Clinical data from 25 954 patients were reviewed and 804 (3.1%) were found to have become infected at the surgical site. Older age (≥60 years) was a risk factor (OR 2.218) and younger age (<18 years) was a protective factor (OR 0.258). Diabetes mellitus (OR 6.560) and hypertension (OR 3.991) were independent risk factors. Compared with type II incisions, type I incisions had a lower risk for SSI (OR 0.031), while type III incisions had a greater risk of SSI (OR 2.599). Compared with upper limbs and hands, the feet had a lower risk of infection, while surgery performed at the spine and joints did not increase the risk as compared with foot surgery.

Conclusion

Older age, hypertension, diabetes mellitus and type III incisions were risk factors for SSI following orthopaedic surgery.

Malnutrition in the Outcome of Wound Healing at Public Hospitals in Bahir Dar City, Northwest Ethiopia: A Prospective Cohort Study

Background

Poor nutritional status affects the normal process of the wound healing stage. There is limited evidence regarding the association between malnutrition and wound healing in Ethiopia.

Objective

To assess the association between nutritional status and wound healing progress among adult individuals who had undergone abdominal surgery at Public Hospitals, Ethiopia.

Methods

A prospective cohort study was conducted on 310 adult patients who had undergone abdominal surgery from August to December 2019. Data were collected using a standardized, structured, and pretested questionnaire. Anthropometric and serum albumin measurements were used to measure nutritional status. A multivariable Cox-regression analyses model was fitted to show the association between malnutrition and wound healing and p value < 0.05 was used to declare statistical significance value.

Results

The cumulative incidence rate of good wound healing was 65.5% (95% CI: 60.0–71.0). Patients who had normal preoperative body mass index (adjusted hazard ratio (AHR) = 2.22 (95% CI: 1.55–3.19)) and normal range of serum albumin level (≥3.5) (AHR = 1.56 (95% CI: 1.05–2.29)) were significantly associated with better wound healing outcomes.

Conclusion

Nutritional status had a strong association with good wound healing outcomes. Therefore, nutritional status screening should be done for all adult patients before undergoing abdominal surgery to improve wound healing outcomes and reduce hospital stays.

Surgical site infection and its association with rupture of membrane following cesarean section in Africa: a systematic review and meta-analysis of published studies

Introduction

Surgical site infection occurs within 30 days after a surgical procedure and involves the skin, subcutaneous tissue, and soft tissue. Surgical site infection following cesarean section is a common postoperative complication and is associated with maternal morbidity and mortality in resource-limited settings. Even though the proportion of surgical site infection and some risk factors were reported by kinds of literature, varying results were stated across studies. There is also limited knowledge on the association between postpartum surgical site infection and the rupture of membrane. Hence, this systematic review and meta-analysis was designed to estimate the pooled proportion of surgical site infection and its association with rupture of membrane following cesarean section in Africa.

Methods

Studies published from January 01, 2000 to January 30, 2020 were searched from MEDLINE via PubMed, Scopus, Medscape, Web-science and CINAHL databases to search relevant published articles. We also performed a manual search of reference lists of key articles to retrieve additional relevant articles. Initially, 559 records were identified and 15 studies included in the analysis. The statistical analysis was performed using STATA 11. Heterogeneity between-study was explored by forest plot and inconsistency index (I²). The publication bias was checked by a funnel plot and Egger’s test. Pooled estimates of proportion and odds ratio were calculated by a random-effects model with a 95% confidence interval (CI).

Results

The overall pooled proportion of surgical site infection following cesarean section was 10.21% (I² = 86.8, p < 0.000; 95% CI = 8.36, 12.06). The odds of developing surgical site infection among women who had the rupture of membrane before delivery were nearly 6 times higher than those who had not a rupture of the membrane (AOR = 5.65, 95% CI: 3.95–8.07).

Conclusions

The proportion of surgical site infections following the cesarean section is relatively high. Women who had rupture of the membrane before delivery were more likely to develop surgical site infections following the cesarean section. Due attention should be given to the provision of prophylactic antibiotics that can reduce surgical site infection after cesarean delivery.

Current practices and evaluation of barriers and facilitators to surgical site infection prevention measures in Jimma, Ethiopia

Objective:

Surgical site infections (SSIs) greatly burden healthcare systems around the world, particularly in low- and middle-income countries. We sought to employ the Systems Engineering Initiative for Patient Safety (SEIPS) model to better characterize SSI prevention practices and factors affecting adherence to prevention guidelines at Jimma University Medical Center (JUMC).

Design:

Our cross-sectional study consisted of semistructured interviews designed to elicit perceptions of and barriers and facilitators to SSI prevention among surgical staff and observations of current preoperative, perioperative, and postoperative SSI prevention practices in surgical cases. Interviews were recorded, manually transcribed, and thematically coded within the SEIPS framework. Trained observers recorded compliance with the World Health Organization’s SSI prevention recommendations.

Setting:

A tertiary-care hospital in Jimma, Ethiopia.

Participants:

Surgical nurses, surgeons, and anesthetists at JUMC.

Results:

Within 16 individual and group interviews, participants cited multiple barriers to SSI prevention including shortages of water and antiseptic materials, lack of clear SSI guidelines and training, minimal Infection Prevention Control (IPC) interaction with surgical staff, and poor SSI tracking. Observations from nineteen surgical cases revealed high compliance with antibiotic prophylaxis (94.7%), hand scrubbing (100%), sterile gloves and instrument use (100%), incision site sterilization (100%), and use of surgical safety checklist (94.7%) but lower compliance with preoperative bathing (26.3%), MRSA screening (0%), and pre- and postoperative glucose (0%, 10.5%) and temperature (57.9%, 47.3%) monitoring.

Conclusions:

Utilizing the SEIPS model helped identify institution-specific barriers and facilitators that can inform targeted interventions to increase compliance with currently underperformed SSI prevention practices at JUMC.

Objetivo: Verificar a associação entre os fatores de risco e a presença de Infecção de Sítio Cirúrgico em cirurgias traumato-ortopédicas. Materiais e métodos: Estudo prospectivo descritivo, quantitativo, realizado entre agosto a outubro de 2017 com 84 pacientes. Os dados referentes ao paciente, ao procedimento e os sinais de Infecções de Sítio Cirúrgico, encontrados no terceiro e décimo dia de pós-operatório, foram coletados por meio de um formulário. Resultados: Das variáveis estudadas, comportaram-se como fatores de risco de Infecção de Sítio Cirúrgico: tabagismo, diabetes e idade acima de 50 anos. A idade foi o principal fator de risco relacionado ao paciente, presente em 31, 36,9% dos casos. Dor, edema e hiperemia foram os sinais de infecção mais prevalentes. Discussão e conclusões: Os fatores de risco relacionados ao paciente possuem maior relevância na associação com infecção do sítio cirúrgico em comparação com os relacionados ao procedimento.

Evaluation of Surgical Antimicrobial Prophylaxis and Incidence of Surgical Site Infection at Borumeda Hospital, Northeast Ethiopia: Retrospective Cross-Sectional Study

BACKGROUND

Surgical site infections are global healthcare problems. Although surgical site infections are preventable, they still cause significant morbidity, high death rates, and financial stress on national budgets and individual patients. Inappropriate uses of surgical antimicrobial prophylaxis are increasing and worsening patients' quality of life. This study determined the incidence and risk factors of surgical site infections.

METHODS

Institution-based retrospective cross-sectional study was conducted using a structured data abstraction format on patients who were attending at the surgical ward of Borumeda hospital from April 1, 2017, to March 31, 2019. The data were collected during July 15-30, 2019. A systematic random sampling technique was employed to select 227 surgical cases. Multivariate logistic regression was computed using the statistical package for social sciences version 23.

RESULTS

The incidence of surgical site infections was 46.7%. Prophylaxis was administered to 188 (82.8%) surgical cases. Prophylaxis was recommended for 151 (66.5%). Out of these, only 143 (94.7%) received prophylaxis. One hundred seventy-four (78.4%) of the procedures had appropriate indication. The compliance of surgical antimicrobial prophylaxis use was 13.7%. The predictors of surgical site infections were receiving prophylaxis more than 24 h after surgery (AOR=3.53, 95% CI: 1.22-10.17), clean-contaminated wounds (AOR=4.54, 95% CI: 1.33-15.53), surgical procedure of thyroidectomy (AOR=5.2, 95% CI: 0.9-21.4), appendectomy (AOR = 29, 95% CI: 6.2-141.7), cholecystectomy (AOR = 21, 95% CI: 3.5 -126.7), hernia (AOR= 8.8, 95% CI: 1.2-62.2), skin and deep tissue (AOR = 125, 95% CI: 7.8-196.7), and orthopedic (AOR=57, 95% CI: 1.6-209.5).

CONCLUSION

There was high inconsistency between surgical antimicrobial prophylaxis practice and international surgical site infections prevention guideline. Wrong selection of antimicrobial agents was the most noncompliant to the guidelines. The incidence of surgical antimicrobial prophylaxis was high and requires due attention. The duration of postoperative prophylaxis should be kept to less than 24 h.

Surgical Site Infections and Prophylaxis Antibiotic Use in the Surgical Ward of Public Hospital in Western Ethiopia: A Hospital-Based Retrospective Cross-Sectional Study

Objective

Surgical site infection (SSI) is one of the leading causes of hospital-acquired infection among hospitalized patients. It causes significant health problems and results in an extended length of hospital stay, increased cost, and increased patient morbidity and mortality. To prevent the development of SSI, surgical antibiotic prophylaxis (SAP) administration before surgery is an evidence-based practice. Therefore, this study aimed to assess the prevalence of SSIs and surgical antibiotic prophylaxis practice, and identifying the gap in practicing prophylactic surgical antibiotic use.

Methods

A retrospective cross-sectional study design was conducted on randomly selected 281 participants who fulfilled the inclusion criteria. Appropriateness of surgical antibiotic prophylaxis was assessed by clinical pharmacists based on the standard treatment guideline. Descriptive and multivariate logistic regression analyses were performed in SPSS version 25. Statistical significance was set at p <0.05.

Results

The overall prevalence of SSI was 19.6% (95% CI: 19-20.2). Majority of surgical patients (88.6%) got surgical antibiotic prophylaxis. Ceftriaxone and metronidazole (45.4%), and ceftriaxone (33.3%) were the most frequently used prophylactic antibiotics. Presence of comorbidity (AOR=9.18, 95% CI: 5.17-17.9, p<0.001), contaminated (AOR=6.01, 95% CI: 1.77-16.8, p=0.019) and dirty (AOR=7.20, 95% CI: 1.23-12.1, p=0.029) wound classes, devoid of prophylactic antibiotics (AOR=6.63, 95% CI: 0.89-19.3, p=0.006), the timing of prophylactic antibiotic administration between 1 hour and 2 hours before incision (AOR=8.2, 95% CI: 4.34-18.1, p=0.001), and 48 hours duration of surgical antimicrobial prophylaxis (AOR=7.20, 95% CI: 1.23-28.17, p=0.027) were significantly associated with the development of SSIs.

Conclusion

The prevalence of SSI was relatively high despite most surgical patients were given prophylactic antibiotics. The presence of comorbidity, contaminated and dirty wound classes, devoid of prophylactic antibiotics, administering prophylactic antibiotics between 1 hour and 2 hours before incision, and 48 hours duration of surgical antibiotic prophylaxis were significantly associated with SSIs.

The Association Between Incorrect Use of Antibiotic Prophylaxis and in-Hospital Surgical Site Infections - A Prospective Observational Study

Background

Surgical site infection (SSI) is the most prevalent in developing countries where 61–90% of cases develop in-hospital. The study aimed to assess the correctness of antibiotic prophylaxis (AP) use, the incidence of in-hospital SSI, and its determinants.

Patients and Methods

A 3-month hospital-based prospective observational study design was used on general surgery patients. The criteria for identification of SSI were performed based on the Center for Disease Control and Prevention’s (CDC’s) definition of SSI. The correctness of AP was performed based on the American Society of Health System Pharmacist 2013 guideline (ASHP). Multiple stepwise backward logistic regression analysis was used at p-value <0.05 to predict SSI.

Results

Of 269 adult patients, the type of admission was almost equal between emergency and elective surgery. The mean (± SD) age of the study participants was 41.95±17.764. Only 19.7% of the study participants used AP correctly. The incidence rate of in-hospital SSI was 16.7% (45/269), which corresponds to 45/4736 or 9.5/1000 person-days. Independent predictors for SSI were American Society of Anesthesiology (ASA) class III–IV (p-value <0.0001), patients with age-adjusted Charlson co-morbidity index (CCI) of ≥1 score (p value=0.008), and incorrect use of AP (p-value =0.025).

Conclusion

Incorrect antibiotic prophylaxis use contributed to an increased risk of SSI, which needs urgent attention in the present study area.

Supporting global antimicrobial stewardship: antibiotic prophylaxis for the prevention of surgical site infection in low- and middle-income countries (LMICs): a scoping review and meta-analysis

BACKGROUND

The Scottish Antimicrobial Prescribing Group is supporting two hospitals in Ghana to develop antimicrobial stewardship. Early intelligence gathering suggested that surgical prophylaxis was suboptimal. We reviewed the evidence for use of surgical prophylaxis to prevent surgical site infections (SSIs) in low- and middle-income countries (LMICs) to inform this work.

METHODS

MEDLINE, Embase, Cochrane, CINAHL and Google Scholar were searched from inception to 17 February 2020 for trials, audits, guidelines and systematic reviews in English. Grey literature, websites and reference lists of included studies were searched. Randomized clinical trials reporting incidence of SSI following Caesarean section were included in two meta-analyses. Narrative analysis of studies that explored behaviours and attitudes was conducted.

RESULTS

This review included 51 studies related to SSI and timing of antibiotic prophylaxis in LMICs. Incidence of SSI is higher in LMICs, infection surveillance data are poor and there is a lack of local guidelines for antibiotic prophylaxis. Education to improve appropriate antibiotic prophylaxis is associated with reduction of SSI in LMICs. The random-effects pooled mean risk ratio of SSI in Caesarean section was 0.77 (95% CI: 0.51-1.17) for pre-incision versus post-incision prophylaxis and 0.89 (95% CI: 0.55-1.14) for short versus long duration. Reduction in cost and nurse time was reported in shorter-duration surgical antibiotic prophylaxis.

CONCLUSIONS

There is scope for improvement, but interventions must include local context and address strongly held beliefs. Establishment of local multidisciplinary teams will promote ownership and sustainability of change.

Two years study of prevalence and antibiotic resistance pattern of Gram-negative bacteria isolated from surgical site infections in the North of Iran

Objective

The present study aimed to investigate the frequency and antibiotic susceptibility pattern of Gram-negative bacteria (GNB) isolated from surgical site infections (SSIs) in the North of Iran.

Results

This cross-sectional study conducted over a two-year period during 2018–2020 on all cases of SSIs who had a positive culture for a GNB. Standard microbiological tests were followed for the bacterial isolation and identification. Antimicrobial susceptibility profiles were determined using disk diffusion method. During the study period, a total of 78 nonduplicated GNB isolated from SSIs. The most prevalent surgical procedures were fracture fixation (37.2%), and tissue debridement (23.1%). Klebsiella isolates showed the highest isolation rate (29.5%) followed by Enterobacter (28.2%), and Acinetobacter (16.7%). Antibiotic susceptibility results showed that Acinetobacter isolates were almost resistant to all of the tested antibiotics, except gentamicin, co-trimoxazole, and meropenem. Enterobacteriaceae isolates showed the lowest resistance against amikacin, co-trimoxazole, and imipenem. Overall, 49 (62.8%) of isolates were multiple drug-resistant (MDR). In summary, a remarkable rate of MDR isolates which showed an increasing trend during recent years is a serious alarm for the management of SSIs caused by GNB. Moreover, the results of regional assessments, provide good epidemiological background for comparing our situation with other regions.

Prevalence of surgical site infection and its associated factors after cesarean section in Ethiopia: systematic review and meta-analysis

BACKGROUND

Surgical site infection (SSI) affects nearly one third of patients who have undergone a surgical procedure. It is a significant and substantial cause of surgical patient morbidity and mortality later with human and financial costs threat. There are fragmented and pocket studies which reported the prevalence of SSI among mothers who experienced for cesarean section and its risk factors. However, there is no any solid evidence established at the national level; which was also the interest of the authors to fill this gap. Therefore, this systematic review and meta-analysis aimed to estimate the pooled prevalence of SSI after cesarean section and its associated factors at national level.

METHODS

Original articles were searched in PubMed, MEDLINE, EMBASE, CINAHL, Google Scholar, HINARI portal, and Cochrane Library. All observational studies defined outcome of variable "SSI as infection related to an operation procedure that occur at or near surgical incision within 30 days of operation or after one year if an implant is placed" were considered. Data were extracted using standard data extraction excel spread sheet checklists developed according to 2014 Joanna Briggs Institute Reviewers' Manual after the quality was assessed through Newcastle-Ottawa quality assessment scale. The I² statistic was used to quantify heterogeneity across studies. Funnel plot asymmetry and Egger's tests were used to check for publication bias. A fixed effect model was used to estimate the pooled prevalence of SSI. Odds Ratio (OR) with 95% Confidence Interval (CI) was also considered to determine the association of identified variables with SSI. Statistical analysis was conducted using STATA version 14 software.

RESULT

From initial 179 identified articles, 11 were eligible for inclusion in the final systematic review and meta-analysis. Studies with a score of 6 and above were included for final analysis. All included studies were institutional based cross sectional. The pooled estimate of SSI after cesarean section in Ethiopia was 9.72% (95%CI: 8.38, 11.05). Premature rapture of membrane (PROM) > 12 h (OR = 5.32, 95%CI: 3.61, 7.83), duration of labor> 24 h (OR = 3.67, 95%CI: 2.45, 5.48), chorioamnionitis (OR = 9.11, 95%CI: 5.21, 15.93), anemia (OR = 4.56, 95%CI: 2.88, 7.22) and having vertical skin incision (OR = 4.17, 95%CI: 2.90, 6.02) had increased odds of developing SSI after cesarean section.

CONCLUSION

The prevalence of SSI after cesarean section in Ethiopia was high compared with the sphere standards of communicable disease control (CDC) guidelines for SSI after cesarean section. Therefore, Ministry of Health with its stake holders should give special emphasis on community and institution based programs in manner to prevent prolonged labor, PROM, chorioamnionitis and anemia which will also have synergistic impact on SSI after cesarean section. Moreover, there is also a call to health professionals not to use vertical incision as primary option of cesarean section to reduce the risk of developing surgical site infection among mothers.

Surgical site infection and its associated factors in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Despite being a preventable complication of surgical procedures, surgical site infections (SSIs) continue to threaten public health with significant impacts on the patients and the health-care human and financial resources. With millions affected globally, there is significant variation in the primary studies on the prevalence of SSIs in Ethiopia. Therefore, this study aimed to estimate the pooled prevalence of SSI and its associated factors among postoperative patients in Ethiopia.

METHODS

PubMed, Scopus, Psyinfo, African Journals Online, and Google Scholar were searched for studies that looked at SSI in postoperative patients. A funnel plot and Egger's regression test were used to determine publication bias. The I2 statistic was used to check heterogeneity between the studies. DerSimonian and Laird random-effects model was applied to estimate the pooled effect size, odds ratios (ORs), and 95% confidence interval (CIs) across studies. The subgroup analysis was conducted by region, sample size, and year of publication. Sensitivity analysis was deployed to determine the effect of a single study on the overall estimation. Analysis was done using STATA™ Version 14 software.

RESULT

A total of 24 studies with 13,136 study participants were included in this study. The estimated pooled prevalence of SSI in Ethiopia was 12.3% (95% CI: 10.19, 14.42). Duration of surgery > 1 h (AOR = 1.78; 95% CI: 1.08-2.94), diabetes mellitus (AOR = 3.25; 95% CI: 1.51-6.99), American Society of Anaesthesiologists score > 1 (AOR = 2.51; 95% CI: 1.07-5.91), previous surgery (AOR = 2.5; 95% CI: 1.77-3.53), clean-contaminated wound (AOR = 2.15; 95% CI: 1.52-3.04), and preoperative hospital stay > 7 day (AOR = 5.76; 95% CI: 1.15-28.86), were significantly associated with SSI.

CONCLUSION

The prevalence of SSI among postoperative patients in Ethiopia remains high with a pooled prevalence of 12.3% in 24 extracted studies. Therefore, situation based interventions and region context-specific preventive strategies should be developed to reduce the prevalence of SSI among postoperative patients.

Management of hospital-acquired infections among patients hospitalized at Zewditu memorial hospital, Addis Ababa, Ethiopia: A prospective cross-sectional study

BACKGROUND

Hospital-Acquired Infections (HAIs) are acquired when the patient is hospitalized for more than 48 hours. In Ethiopia data are scarce in management appropriateness of HAIs. Hence, this study was aimed to assess the prevalence and management of HAIs among patients admitted at Zewditu Memorial Hospital.

METHOD

A facility based prospective cross sectional study was conducted from March 1, 2017 to August 30, 2017. The sample was proportionally allocated among (medical, pediatrics, gynecology and obstetrics and surgical) wards, based on patient flow. Data were collected using data abstraction format and supplemented by key informant interview. Interview was made on eight physicians and four microbiologists who have been working in the wards during study period. Management appropriateness was assessed using Infectious Disease Society of America guideline and experts opinion (Infectious disease specialist). A multivariate logistic regression was used to identify factors associated with HAIs.

RESULT

The prevalence of HAIs was 19.8%. Surgical Site Infection (SSI) and pneumonia accounted for 20 (24.7%) of the infections. Culture and sensitivity was done for 24 (29.6%) patients. Of the 81 patients who developed HAIs, 54 (66.67%) of them were treated inappropriately. Physicians' response for this variation was information gap, forgetfulness, affordability and availability issue of first line medications. Younger age (AOR (Adjusted odds ratio) = 8.53, 95% CI: 2.67-27.30); male gender (AOR = 2.06, 95% CI: 1.01-4.22); longer hospital stay (AOR = 0.17, 95% CI: 0.06-0.51); and previous hospital admission (AOR = 3.22, 95% CI: 1.76-5.89); were independent predictors of HAIs.

CONCLUSION

Prevalence of HAIs and inappropriate management were substantially high in this study. Pneumonia and SSI were the common types of HAIs. Locally conformable guidelines could help to correct such problems.

Practice of and associated factors regarding prevention of surgical site infection among nurses working in the surgical units of public hospitals in Addis Ababa city, Ethiopia: A cross-sectional study

Background

Surgical site infections are one of the commonest types of healthcare-associated infections. Up to 60% of these infections are estimated to be preventable by using evidence-based guidelines. As a front line caregiver, nurses are responsible for the majority of preventive activities. Hence, the enhanced practical skill of nurses is an essential component in preventive actions.

Objective

The aim of this study was to assess the practice of nurses and identify factors associated with it regarding prevention of surgical site infections in Addis Ababa city public hospitals.

Methods

An institution-based cross-sectional study was carried out from March 01–30, 2018. An adapted and pretested, self-administered questionnaire was utilized as a data collection tool. A stratified random sampling technique was employed by considering the level of hospitals as a stratum. Data were entered into a computer using Epi-data 3.1 statistical package. Then, it was exported to SPSS Version 23 for further analysis. Descriptive statistics were computed for the study variables. Bivariate regression analysis was also run to assess the association between independent variables and the level of nurse’s practice. To see the relative effect of independent variables on the nurse’s practice, a multivariable regression analysis was carried out.

Result

A total of 409 nurses returned the questionnaire with a response rate of 98%. Majority (60.4%) of the participants were females and 84.1% were BSc holders. Less than half, (48.9%) of the participants were found to have good practice regarding prevention of surgical site infection. Being male, having more work experience, higher educational level and using available infection prevention guidelines were significantly associated with practice at p <0.05.

Conclusion

More than half of the participants have inadequate practice regarding prevention of surgical site infection. Training nurses, making surgical site infection prevention guidelines easily accessible and ensuring possessed knowledge by nurses is potent enough and can be translated into desirable actions are recommended.

Value and Feasibility of Telephone Follow-Up in Ethiopian Surgical Patients

Background: Surgical site infections (SSIs) represent a major cause of morbidity and mortality in Ethiopia. Lack of post-discharge follow-up, including identification of SSIs, is a barrier to continued patient care, often because of financial and travel constraints. As part of a surgical quality improvement initiative, we aimed to assess patient outcomes at 30 days post-operative with a telephone call. Patients and Methods: We conducted mobile telephone follow-up as part of Lifebox's ongoing Clean Cut program, which aims to improve compliance with intra-operative infection prevention standards. One urban tertiary referral hospital and one rural district general hospital in Ethiopia were included in this phase of the study; hospital nursing staff called patients at 30 days post-operative inquiring about signs of SSIs, health-care-seeking behavior, and treatments provided if patients had any healthcare encounters since discharge. Results: A total of 701 patients were included; overall 77% of patients were reached by telephone call after discharge. The rural study site reached 362 patients (87%) by telephone; the urban site reached 176 patients (62%) (p < 0.001). Of the 39 SSIs identified, 19 (49%) were captured as outpatient during the telephone follow-up (p < 0.001); 22 (34%) of all complications were captured following discharge (p < 0.001). Telephone follow-up improved from 65%-78% in the first half of project implementation to 77%-89% in the second half of project implementation. Conclusion: Telephone follow-up after surgery in Ethiopia is feasible and valuable, and identified nearly half of all SSIs and one-third of total complications in our cohort. Follow-up improved over the course of the program, likely indicating a learning curve that, once overcome, is a more accurate marker of its practicability. Given the increasing use of mobile telephones in Ethiopia and ease of implementation, this model could be practical in other low-resource surgical settings.
