Incidence and risk factors for surgical site infections in obstetric and gynecological surgeries from a teaching hospital in rural India

Algerian postcaesarean surgical site infections: A cross-sectional investigation of the epidemiology, bacteriology, and antibiotic resistance profile

BACKGROUND

Surgical site infections (SSIs) are one of the most common health care-associated infections in low and middle-income countries. The aims of this cross-sectional descriptive study were to estimate the frequency of postcaesarean infection with associated clinical characteristics and the antibiotic resistance profile of bacterial isolates.

METHODS

Patients who underwent a cesarean section at the obstetrics and gynecology department of the hospital in Annaba, Algeria were included. Each woman was followed postoperatively for 30 days and sociodemographic data were collected. Culture-based microbiological methods were used to identify the causative bacteria and determine their antibiotic resistance phenotype and molecular characterization.

RESULTS

Among 1,810 patients, we recorded 36 (1.9%) SSIs. Most patients had undergone an emergency delivery (75%) and low educational level (72.2%). The most frequent maternal pathologies were Body Mass Index ≥ 30 (63.9%), scarred uteri (58.3%), anemia (55.6%), and an American Society of Anaesthesiologists score between II and III (33.3%). Of the 43 bacteria isolated, Enterobacteriaceae were the most frequent (62.8%), predominated by Escherichia coli strains (43.5%), a majority of which were extended-spectrum β-lactamases carriers (62.9%). Although gram-positive cocci were less frequent (37.2%), a majority of Enterococcus faecalis (56.2%) were observed and 2 strains of vancomycin-resistant Enterococcus faecium harboring the vanA gene were identified.

CONCLUSIONS

Extensive surveillance of at-risk populations should be integrated to prevent the occurrence of SSIs.

Risk factors for surgical site infection in patients undergoing obstetrics and gynecology surgeries: A meta-analysis of observational studies

OBJECTIVE

The aim of this study was to identify the risk factors for surgical site infection (SSI) in patients undergoing obstetrics and gynecology surgeries through meta-analysis.

METHODS

Relevant original studies published from January 1945 to May 2023 were searched the CBM, PubMed, Embase, WOS, CNKI, Wanfang, vip, and Cochrane Library databases. Studies eligible were evaluated by two investigators following Newcastle-Ottawa Scale(NOS) criteria. Review Manager 5.3 software was used to analyse the combined effect sizes and test for heterogeneity, and Stata 14.0 software's Begg's Test and Egger's Test were used to test for bias.

RESULTS

13 case-control articles, including 860 cases in the case group and 13574 cases in the control group, met the inclusion criteria. Eventually, Our meta-analysis showed that SSI in patients undergoing obstetrics and gynecology surgeries was correlated with body mass index (BMI)≥24 (OR = 2.66; P < 0.0001), malignant lesions (OR = 4.65; P < 0.0001), operating time≥60min (OR = 2.58; P < 0.0001), intraoperative bleeding≥300ml (OR = 2.54; P < 0.0001), retained urinary catheter (OR = 4.45; P < 0.0001), and vaginal digital examination≥3times (OR = 2.52; P < 0.0001).

CONCLUSION

In this study, BMI≥24, intraoperative bleeding≥300ml, malignant lesions, operating time≥60min, retained urinary catheter, and vaginal digital examination≥3times were considered as independent risk factors for SSI in obstetrics and gynecology surgery. It is recommended that scholars be rigorous in designing the experimental process when conducting case-control or experimental studies in order to improve the quality of the study. Controlling patients' weight before obstetrical and gynecological surgery, shortening the operation time intraoperatively, and strictly controlling the indications of vaginal digital examination and retained urinary catheter can effectively reduce the incidence of SSI.

Effectiveness of Gentamicin Wound Irrigation in Preventing Surgical Site Infection During Lumbar Spine Surgery: A Retrospective Study at a Rural Teaching Hospital in India

BACKGROUND

Surgical site infections (SSIs) are an opposing result of surgery and account for the majority of healthcare-related infections worldwide. It is one of the most common complications associated with open-spine surgery and is associated with high rates of mortality and high demand for healthcare resources. Surgical site infections are the result of a variety of reasons, which is why a range of prevention strategies have been proposed. Intraoperative wound irrigation (IOWI) is a simple procedure that involves moving a solution through an open wound to help hydrate the tissue. It is a type of prophylactic wound irrigation. It removes and dilutes bodily fluids, bacteria, and cellular debris. It may also act as a bactericidal agent when used with antibiotics and antiseptics.

AIMS AND OBJECTIVES

To evaluate the incidence of SSI in lumbar spine surgeries by comparing IOWI with normal saline containing gentamicin (NS-G) and normal saline (NS) alone.

MATERIALS AND METHOD

A hospital-based retrospective study was conducted among 40 patients who underwent elective lumbar spine surgery at the Department of Orthopaedics, RL Jalappa Hospital Centre, Kolar, Karnataka, India.

RESULT

Out of the total participants enrolled, 60% were males and 40% were females. There was no statistically significant difference found between mean age, mean BMI, mean hemoglobin level, mean WBC counts, and mean fasting blood sugar (FBS) levels among both groups. The overall prevalence of SSI among patients was 25%. In Group A (NS-G), the prevalence of SSI was 15%, and in Group B (NS), it was 35%. In total, 17.5% of study participants had superficial SSI, while 7.5% had deep SSI.

CONCLUSION

Gentamicin, an aminoglycoside antibiotic, is bactericidal and efficient against gram-positive organisms like Staphylococcus, the most frequent pathogen causing SSI in spine surgery. During lumbar spine surgery, IOWI with saline and gentamicin before closure is more effective in preventing SSI than simple saline irrigation.

Exploring the perioperative infection control practices & incidence of surgical site infections in rural India

BACKGROUND

Surgical site infections (SSIs) affect around a third of patients undergoing surgeries worldwide, annually. It is heterogeneously distributed with a higher burden in low and middle-income countries. Although rural and semi-urban hospitals cater to 60-70% of the Indian population, scarce data regarding SSI rates are available from such hospitals. The study aimed to determine the prevalent SSI prevention practices and existing SSI rates in the smaller rural and semi-urban hospitals in India.

METHODS

This is a prospective study performed in two phases involving surgeons and their hospitals from Indian rural and semi-urban regions. In the first phase, a questionnaire was administered to surgeons enquiring into the perioperative SSI prevention practices and five interested hospitals were recruited for phase two which documented the rate of SSIs and factors affecting them.

RESULTS

There was full compliance towards appropriate perioperative sterilisation practices and postoperative mop count practice at the represented hospitals. But prophylactic antimicrobials were continued in the postoperative period in more than 80% of the hospitals. The second phase of our study documented an overall SSI rate of 7.0%. The SSI rates were influenced by the surgical wound class with dirty wounds recording six times higher rate of infection than clean cases.

CONCLUSIONS

SSI prevention practices and protocols were in place in all the less-resourced hospitals surveyed. The SSI rates are comparable or lower than other LMIC settings. However, this is accompanied by poor implementation of the antimicrobial stewardship guidelines.

Risk factors for surgical site infection after abdominal hysterectomy, New York State, 2015-2018

OBJECTIVE

To identify risk factors for surgical site infections (SSIs) after abdominal hysterectomy (HYST) procedures using National Healthcare Safety Network (NHSN) data augmented with diagnosis codes available using administrative data.

METHODS

We analyzed 66,001 HYST procedures in 166 New York State hospitals between January 2015 and December 2018, reported in NHSN, and matched to billing data. Risks factors for SSI after abdominal hysterectomy were identified using logistic regression models.

RESULTS

A total of 66,001 HYST procedures were analyzed. SSI was reported following 1,093 procedures, resulting in an infection rate of 1.66%. Risk factors associated with SSIs were open approach (not laparoscopic) with an adjusted odds ratio (AOR) of 2.72 and 95% confidence interval (CI) of 2.37-3.12, contaminated or dirty wound class (AOR 2.28, 95% CI 1.61-3.24), body mass index ≥30 (AOR 1.78, 95% CI 1.56-2.02), procedures lasting 186 minutes or more (AOR 1.78, 95% CI 1.56-2.02), American Society of Anesthesia (ASA) score ≥3 (AOR 1.74, 95% CI 1.52-1.99), gynecological cancer (AOR 1.54, 95% CI 1.32-1.80), and diabetes mellitus (AOR 1.46, 95% CI 1.24-1.70).

CONCLUSION

Obesity, prolonged procedure duration, diabetes mellitus, wound contamination, open approach, ASA score ≥3, and gynecological cancer were significant independent risk factors associated with SSI after hysterectomy.

Rational use of antibiotics for major elective gynaecological and obstetrical surgical procedures: quality improvement journey from a tertiary care public facility

BACKGROUND

Antibiotic resistance is a global problem. Irrational use of antibiotics is rampant. Guidelines recommend administration of single dose of antibiotic for surgical antimicrobial prophylaxis (SSAP) for elective obstetrical and gynaecological surgeries. However, it is not usually adhered to in practice. Majority of women undergoing elective major gynaecological surgeries and caesarean sections in the department of obstetrics and gynaecology of our tertiary level heavy case load public health facility were receiving therapeutic antibiotics (for 7-10 days) instead of recommended SSAP. Our aim was to increase the SSAP in our setting from a baseline 2.1% to more than 60% within 6 months.

METHODS

After root cause analysis, we formulated the departmental antimicrobial policy, spread awareness and sensitised doctors and nursing officers regarding antimicrobial resistance and asepsis through lectures, group discussions and workshops. We initiated SSAP policy for elective major surgeries and formed an antimicrobial stewardship team to ensure adherence to policy and follow processes and outcomes. The point of care quality improvement (QI) methodology was used. Percentage of patients receiving SSAP out of all low-risk women undergoing elective surgery was the process indicator and percentage of patients developing surgical site infection (SSI) of all patients receiving SSAP was the outcome indicator. The impact of various interventions on these indicators was followed over time with run charts.

RESULTS

SSAP increased from a baseline 2.1%-67.7% within 6 months of initiation of this QI initiative and has since been sustained at 80%-90% for more than 2 years without any increase in SSI rate.

CONCLUSION

QI methods can rapidly improve the acceptance and adherence to evidence-based guidelines in a busy public healthcare setting to prevent injudicious use of antibiotics.

Skin and mucous membranes colonisation with Staphylococcus aureus or MRSA as a risk factor for surgical site infections in elective Caesarean Section

The purpose of this study was to determine if skin and mucous membrane colonisation with Staphylococcus aureus (S. aureus) and methicillin-resistant Staphylococcus aureus (MRSA) increases the incidence of surgical site infection (SSI) post-elective Caesarean Sections. A prospective study was conducted at a major centre in Jordan, involving 127 patients who underwent elective Caesarean Section surgeries during 2019. Participants were screened for skin and mucous membranes colonisation for S. aureus preoperatively and were followed for 90 days for any signs of SSI. The screening sites were on three parts of the patients' bodies; nose, throat, and groyne. The total SSI incidence was 18.9%. Among participants with SSI; 66.7% had a superficial infection and 33.3% had deep tissue infection. Skin and mucous membrane colonisation was positive in 42 participants (33.1%) in one of the three screening sites. Participants with positive skin and mucous membrane colonisation were found to have SSI incidence 2.43 times more than the non-colonised participants (Fisher's Exact test = 3.832, p = .05, CI: 0.098-6.02). Participants with S. aureus skin and mucous membranes colonisation were significantly 2.94 times with more SSI incidence than those who were not colonised (Fisher's Exact test = 5.485, p = .02, CI: 1.164-7.439). Skin and mucous membrane colonisation was found to increase the incidence of SSI. More attention should be performed to screen for skin and mucous membranes colonisation and subsequent selective skin decolonisation to decrease SSI incidence.IMPACT STATEMENTWhat is already known on this subject? Surgical site infection (SSI) is a challenge that increases the costs of health care. Surgical site infection is associated with high costs mainly due to the increase in the length of hospital stay. Skin screening for S. aureus or MRSA colonisation was found to be important for selective skin decolonisation using appropriate antiseptic preparation and preoperative antibiotic prophylaxis.What do the results of this study add? The incidence of SSI in the colonised group was found to be 2.43 times higher than in the non-colonised group.What are the implications of these findings for clinical practice and/or further research? Screening for colonisation and subsequent selective skin decolonisation should be a part of SSI prevention policies.

Wound Infection Incidence and Obesity in Elective Cesarean Sections in Jordan

Background:

Wound infection is a challenge that face healthcare facilities.

Objective:

The aim of the study was to assess the effect of obesity on wound infection incidence.

Methods:

A prospective study involved 127 patients underwent elective Cesarean section surgeries in the first ten months of 2018 with a follow up period of 90 days.

Results:

The wound infection incidence was 37.8%; the suture infection was 15.7% and SSI was 22%, which divided into: the superficial SSI among 23 (82.1%) patients, and deep tissue SSI among five (17.9%) patients. Obese patients with BMI of 30 kg/m2 or more were significantly at higher risk for wound infections than those whose BMI less than 30 kg/m2 (p= 0.02, relative risk= 2.363).

Conclusion:

Obese patients who underwent Cesarean sections were found to have higher risk to develop wound infections. A larger scale study is needed to determine other associated risk factors.

Intraoperative and Postoperative Complications in Gynaecological Surgery: A Retrospective Analysis

Background and objective Surgical complications can arise either intraoperatively or postoperatively. The factors that lead to complications in gynaecological surgeries could be both patient-related or surgeon-related. In this study, we aimed to identify the frequency of intraoperative and postoperative complications in gynaecological surgeries conducted at our institution and to evaluate various risk factors that may predispose patients to these complications. Materials and methods  This was a retrospective analysis of women undergoing gynaecological surgeries in the Department of Obstetrics and Gynaecology at a tertiary centre in Uttarakhand, India from February 2016 to December 2019. Demographic characteristics, comorbidities, and perioperative complications of these women were recorded. Results A total of 389 women undergoing gynaecological surgeries were included in the study cohort. Of note, 94 of these had perioperative complications, accounting for 24.16% of the total cases. The most common route of surgery associated with complications was open abdominal surgery (34.66%). The operating time in most surgeries ranged from two to three hours (48.93%), and the average duration of hospital stay after surgery was 10.79 + 7.91 days. Intraoperative and postoperative complication rates were 5.91% and 19.28% respectively. Of these, surgical site infections (SSIs) (10.28%) and fever (5.39%) were the most common complications observed. Independent parameters like age, parity, route of surgery, operative time, preoperative duration of hospital stay, and preoperative blood transfusion were significantly associated with perioperative complications. Conclusions Surgical complications were more frequently seen in abdominal cases compared to other routes. Knowledge of centre-specific surgical outcome data can help in providing patients with better preoperative counselling.

Magnitude and factors associated with surgical site infection among mothers underwent cesarean delivery in Nekemte town public hospitals, western Ethiopia

Background

Surgical site infection (SSI) is a serious public health problem due to its impacts on maternal morbidity and mortality and it can have a significant effect on quality of life for the patient. However, little has been studied regarding the magnitude and factors associated with SSI among women underwent cesarean delivery (CD) in study area. Therefore, the aim of this study was to assess the magnitude and factors associated with SSI among women underwent cesarean delivery in Nekemte Town Public Hospitals 2020.

Methods

An institution based cross-sectional study was conducted from January 1/2018 to January 1/2020. A simple random sampling technique was employed to select 401 patient cards from all records women underwent CD from January 1/2018 to January 1/2020. Epidata version 3.2 was used for data entry, and STATA version 14 was used for analysis. A logistic regression model was used to determine the association of independent variables with the outcome variable and adjusted odds ratios (AOR) with 95% confidence interval was used to estimate the strength of the association.

Results

Three hundred eight two (382) cards of women were selected for analysis making a response rate of 95.2%. The mean (±SD) age of the mothers was 25.9 (±4.8) years. The prevalence of SSIs was 8.9% (95% CI: 6.03, 11.76). Age > 35 years (AOR = 5.03, 95% CI:1.69, 14.95), pregnancy-induced hypertension (AOR = 5.63, 95%CI:1.88, 16.79), prolonged labor (AOR = 4.12, 95% CI:1.01, 32.19), receiving general anesthesia (AOR = 3.96 95% CI:1.02, 15.29), and post-operative hemoglobin less than 11 g/dl (AOR = 4.51 95% CI:1.84, 11.07) were significantly associated with the occurrence of SSI after cesarean delivery.

Conclusions and recommendations

The magnitude of post CD SSI in this study was comparable with the sphere standards of CDC guidelines for SSI after CD. Concerned bodies should give due attention the proper utilization of partograph to prevent prolonged labor, and provision of iron folate to increase the hemoglobin level of pregnant mothers in all health institution. In addition, we would recommend the use of spinal anesthesia over general anesthesia.

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.

Predominance of multidrug-resistant Gram-negative organisms as cause of surgical site infections at a private tertiary care hospital in Mumbai, India

Background

This study aims to study the incidence, microbial aetiology and antimicrobial susceptibility of surgical site infections (SSIs) at a private tertiary care hospital in Mumbai, India, and compare it with previously published data from the same institute as well as literature.

Methods

This is a prospective observational study done over 6 years (January 2013-December 2018) at a 750-bed private multi-specialty hospital in Mumbai, India, among all patients undergoing clean and clean-contaminated surgeries. Standard guidelines for preventing, diagnosing and classifying SSIs were followed. The incidence rates of SSI (overall and specialty specific), microbial aetiology and antibiotic susceptibility of SSI were calculated and expressed as percentages.

Results

A total of 55,553 patients underwent clean and clean-contaminated surgeries during the study period. The overall SSI rate was 1.0% (555 cases). The SSI rate in clean surgeries was 0.97% and in clean-contaminated surgeries was 1.03%. Sixty-five per cent of SSIs were due to Gram-negative bacilli, 30% were due to Gram-positive cocci and 4% were due to Candida. Klebsiella pneumoniae (19%), Escherichia coli (17%), Pseudomonas aeruginosa (13%), Staphylococcus aureus(12%) and Enterococcus (10%) were the top five organisms. The overall susceptibility rate of the Gram-negative isolates to beta-lactam-beta-lactamase inhibitor combinations was 60% and carbapenems was 73%. The prevalence of methicillin resistance in S. aureus was 44% and coagulase-negative Staphylococcus was 84%. The crude mortality rate was 1%.

Conclusions

Although the SSI rate is comparable to established international benchmarks, the predominance of multidrug-resistant Gram-negative organisms is a matter of serious concern.

Prevalence and root causes of surgical site infection among women undergoing caesarean section in Ethiopia: a systematic review and meta-analysis

Background

Surgical site infection is a common complication in women undergoing Caesarean section and the second most common cause of maternal mortality in obstetrics. In Ethiopia, prevalence and root causes of surgical site infection post-Caesarean section are highly variable. This systematic review and meta-analysis estimate the overall prevalence of surgical site infection and its root causes among women undergoing Caesarean section in Ethiopia.

Method

Systematic review and meta-analysis were conducted to assess the prevalence and root causes of surgical site infection in Ethiopia. The articles were searched from the databases such as Medline, Google Scholar and Science Direct. A total of 13 studies from different regions of Ethiopia reporting the prevalence and root causes of surgical site infection among women undergoing Caesarean section were included. A random effect meta-analysis model was computed to estimate the overall prevalence. In addition, the association between risk factor variables and surgical site infection related to Caesarean section were examined.

Results

Thirteen studies in Ethiopia showed that the overall prevalence of surgical site infection among women undergoing Caesarean section was 8.81% (95% CI: 6.34–11.28). Prolonged labor, prolonged rupture of membrane, presence of anemia, presence of chorioamnionitis, presence of meconium, vertical skin incision, greater than 2 cm thickness of subcutaneous tissue, and general anesthesia were significantly associated with surgical site infection post-Caesarean section.

Conclusion

Prevalence of surgical site infection among women undergoing Caesarean section was relatively higher in Ethiopians compared with the report of center of disease control guideline. Prolonged labor, prolonged rupture of membrane, presence of anemia, chorioamnionitis, presence of meconium, vertical skin incision, greater than 2 cm thickness of subcutaneous tissue and/or general anesthesia were significantly associated with surgical site infection post-Caesarean section.

Incidence, root causes, and outcomes of surgical site infections in a tertiary care hospital in Rwanda: a prospective observational cohort study

Background

Surgical Site Infections (SSI) are the most reported health acquired infection and common surgical complication in both developed and developing countries. In developing countries such as Rwanda, there is a paucity of published reports on the pattern of SSI, therefore this study aimed at assessing the incidence, risk factors and the antibiotic profile of pathogens responsible of SSI.

Methods

This prospective study included 294 patients admitted between October 10, 2017 and February 12, 2018 to the surgical department of the University Teaching Hospital of Kigali. Patients data were collected using a structured and pretested questionnaire in English version. Regular follow-up was maintained until at least 30 days postoperatively. Samples were collected from suspected wounds and identified using different bacteria culture media. Data were analyzed using Statistical Package for the Social Sciences (SPSS) software word version 20.0. P-value < 0.05 was considered statistically significant.

Results

The overall incidence of SSI was 10.9%. The associated risk factors were found to be an increased age, ASA class, wound classification, skills and experience of the surgeon, longer duration of surgery (> 2 h), prolonged duration of hospital stay, blood transfusion and emergency surgery. The most common pathogens isolated were Klebsiella ssp (55%), followed by Escherichia coli (15%) and Proteus ssp (12%), Acinectobacter (9%), Staphylococcus aureus (6%) and coagulase-negative staphylococci (3%).The pathogens revealed different levels of antibiotic resistance; amoxy-clavilinic acid (98.8%), gentamicin (92.6%), ciprofloxacin (78.1%) and ceftriaxone (53.3%). On the other hand, Amikacin and imipinem were the only two most effective antibiotics for all isolated pathogens with 100% sensitivity.

Conclusion

SSI incidence rate was revealed to be within acceptable international ranges. However, multi drug resistance was seen in half of the isolates leaving clinicians with few choices of drugs for the treatment of patients with SSI. Periodic surveillance of bacteria and antibiotic susceptibility coupled with the implementation of strict protocol for antibiotic administration and operative room regulations are important to minimize the burden of SSI with resistant bacteria pathogens.

Occurrence of Surgical Site Infections at a Tertiary Healthcare Facility in Abuja, Nigeria: A Prospective Observational Study

Surgical site infection (SSI) is one of the most frequent complications of surgical interventions. Several factors have been identified as major determinants of occurrence of SSIs. The present study determined the occurrence and possible risk factors associated with SSIs at a tertiary healthcare facility in Abuja, Nigeria. All patients scheduled for operation in the hospital during the study period and who consented to participate willingly in the study were observed prospectively for the occurrence of SSI based on criteria stipulated by the United States Centre for Disease Control and Prevention (CDC). Data on sociodemographic characteristics, lifestyle, surgical procedure and co-morbidity were collected into a pre-tested data collection tool and analysed using IBM SPSS Statistics software v.24. Predictors of SSIs were identified using multivariate logistic regression model and p-value less than 0.05 was considered statistically significant. Of the 127 surgical patients that met the inclusion criteria comprising 65 (51.2%) females and 62 (48.8%) males between 1 and 83 years with mean age of 25.64 ± 1.66 years, 35 (27.56%; 95% Confidence Interval (CI): 0.205⁻0.360) developed SSIs. Prolonged post-operative hospital stays (p < 0.05), class of wound (p < 0.0001) and some comorbid conditions were found to be significantly associated with higher SSI rate. The SSI rate was highest among patients that had Kirschner-wire insertion (75.0%), followed by an unexpectedly high infection rate among patients that had mastectomy (42.9%), while lower percentages (33.3%) were recorded among patients that had exploratory laparotomy and appendicectomy. The overall magnitude of SSIs in this facility is high (27.6%; 95% CI: 0.205⁻0.360). Several factors were found to be independent predictors of occurrence of SSI. The findings thus highlight the need for improved surveillance of SSIs and review of infection control policies of the hospital.
