Magnitude and Determinant Factors of Surgical Site Infection in Suhul Hospital Tigrai, Northern Ethiopia: A Cross-Sectional Study

Qualitative drivers of postoperative prophylactic antibiotics use and resistance in Ethiopia

BACKGROUND

The World Health Organization (WHO) cautions against unnecessary prolongation of postoperative antibiotics to prevent surgical site infections (SSI), however this practice is still common in many countries. This study aims to describe drivers of prolonged postoperative antibiotic prescribing and clinicians' perspectives on antibiotics resistance and stewardship in Ethiopia.

METHODS

We conducted semi-structured interviews of 16 surgeons and nine surgical ward nurses at three academic referral hospitals in Addis Ababa. Audio recordings were transcribed verbatim and coded. Codes were inductively and iteratively derived between two researchers, tested for inter-rater reliability (IRR), and the codebook was consistently applied to all transcripts. Thematic analysis was performed to understand drivers of prolonged prophylactic antibiotic use in surgical patients.

RESULTS

Interviews revealed factors contributing to postoperative prophylactic antibiotics overprescribing, including inadequate infection prevention and control (IPC) practices, wide variability in local prescribing practices, and distrust in the applicability of WHO guidelines. Antimicrobial resistance was also identified as a major concern by staff. Barriers to improving stewardship included a lack of multidisciplinary teamwork to inform prescribing decisions, while solutions included constructing appropriate context-specific guidelines and improving evidence-based practices through input from local stakeholders, including surgeons, clinical pharmacists, and nurses.

CONCLUSIONS

Study participants perceived that existing evidence and guidelines did not apply in their settings due to high rates of surgical site infections and gaps in perioperative IPC practices (e.g., availability of water for handwashing, sterility breaches). These gaps were a key contributor to prophylactic antibiotic overprescribing, reinforcing the need to strengthen upstream and perioperative surgical antisepsis processes. The findings of this study underscore the importance of engaging multidisciplinary teams in strengthening antimicrobial stewardship efforts, aligning processes to achieve compliance with best practices, and the need for rigorous, contextually appropriate studies from these settings to inform policy.

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.

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.

Scalability and Sustainability of a Surgical Infection Prevention Program in Low-Income Environments

Importance

Surgical infections are a major cause of perioperative morbidity and mortality, particularly in low-resource settings. Clean Cut, a 6-month quality improvement program developed by the global nonprofit organization Lifebox, has demonstrated improvements in postoperative infectious complications. However, the pilot program required intense external programmatic and resource support.

Objective

To examine the improvement in adherence to infection prevention and control standards and rates of postoperative infections in hospitals in the Clean Cut program after implementation strategies were updated and program execution was refined.

Design, Setting, and Participants

This cohort study evaluated and refined the Clean Cut implementation strategy to enhance scalability based on a qualitative study of its pilot phase, including formalizing programmatic and educational materials, building an automated data entry and analysis platform, and reorganizing hospital-based team composition. Clean Cut was introduced from January 1, 2019, to February 28, 2022, in 7 Ethiopian hospitals that had not previously participated in the program. Prospective data initiated on arrival in the operating room were collected, and patients were followed up through hospital discharge and with 30-day follow-up telephone calls.

Exposure

Implementation of the refined Clean Cut program.

Main Outcomes and Measures

The primary outcome was surgical site infection (SSI); secondary outcomes were adherence to 6 infection prevention standards, mortality, hospital length of stay, and other infectious complications.

Results

A total of 3364 patients (mean [SD] age, 26.5 [38.0] years; 2196 [65.3%] female) from 7 Ethiopian hospitals were studied (1575 at baseline and 1789 after intervention). After controlling for confounders, the relative risk of SSIs was reduced by 34.0% after program implementation (relative risk, 0.66; 95% CI, 0.54-0.81; P < .001). Appropriate Surgical Safety Checklist use increased from 16.3% to 43.0% (P < .001), surgeon hand and patient skin antisepsis improved from 46.0% to 66.0% (P < .001), and timely antibiotic administration improved from 17.8% to 39.0% (P < .001). Surgical instrument (38.7% vs 10.2%), linen sterility (35.5% vs 12.8%), and gauze counting (89.2% vs 82.5%; P < .001 for all comparisons) also improved significantly.

Conclusions and Relevance

A modified implementation strategy for the Clean Cut program focusing on reduced external resource and programmatic input from Lifebox, structured education and training materials, and wider hospital engagement resulted in outcomes that matched our pilot study, with improved adherence to recognized infection prevention standards resulting in a reduction in SSIs. The demonstration of scalability reinforces the value of this SSI prevention program.

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.

Infection prevention knowledge, practice, and its associated factors among healthcare providers in primary healthcare unit of Wogdie District, Northeast Ethiopia, 2019: a cross-sectional study

BACKGROUND

Adequate knowledge and safe practice of infection prevention among healthcare providers are vital to prevent nosocomial infections. Thus, this study aimed to assess the level of knowledge and practices of healthcare providers towards infection prevention and its associated factors in the health facilities of Wogdie District, Northern Ethiopia.

METHODS

Institution based cross-sectional study was conducted among 171 healthcare providers who were selected by a simple random sampling technique. Data were collected using interviewer-administered questionnaire. Multivariable logistic regression was performed to identify factors associated with knowledge and practice of infection prevention.

RESULT

About 70.8 and 55.0% of healthcare providers had adequate knowledge and safe practice of infection prevention respectively. Having infection prevention guideline (AOR = 3.65, 95% CI; 1.26, 10.54), taking infection prevention training (AOR = 2.2, 95% CI; 1.01, 4.75), having five years or more work experience (AOR = 1.52:95%CI; 1.13, 4.51), and working in maternity unit (AOR = 1.67:95%CI; 1.38-5.23) were positively associated with adequate knowledge of infection prevention. The odds of safe practice were higher in participants who received infection prevention training (AOR: 2.4; 95% CI; 1.01, 4.75) but lower among healthcare providers who are working in the facility which has no continuous water supply (AOR = 0.48:95% CI; 0.21, 0.83).

CONCLUSION

A significant proportion of healthcare providers had inadequate knowledge and unsafe practice of infection prevention. To improve healthcare worker's knowledge of infection prevention, adequate pre-service as well as on job training should be given.

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.

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.

Are Invasive Procedures and a Longer Hospital Stay Increasing the Risk of Healthcare-Associated Infections among the Admitted Patients at Hiwot Fana Specialized University Hospital, Eastern Ethiopia?

Background

Healthcare-associated infection is a major public health problem, in terms of mortality, morbidity, and costs. Majorities of the cause of these infections were preventable. Understanding the potential risk factors is important to reduce the impact of these avoidable infections. The study was aimed to identify factors associated with healthcare-associated infections among patients admitted at Hiwot Fana Specialized University Hospital, Harar, Eastern Ethiopia.

Methods

A cross-sectional study was carried out among 433 patients over a period of five months at Hiwot Fana Specialized University Hospital. Sociodemographic and clinical data were obtained from a patient admitted for 48 hours and above in the four wards (surgical, medical, obstetrics/gynecology, and pediatrics) using a structured questionnaire. A multivariate logistic regression model was applied to identify predictors of healthcare-associated infections. A p value <0.05 was considered statistically significant.

Results

Fifty-four (13.7%) patients had a history of a previous admission. The median length of hospital stay was 6.1 days. Forty-six (11.7%) participants reported comorbid conditions. Ninety-six (24.4%) participants underwent surgical procedures. The overall prevalence of healthcare-associated infection was 29 (7.4%, 95% CI: 5.2–10.6). Cigarette smoking (AOR: 5.18, 95% CI: 2.15–20.47), staying in the hospital for more than 4 days (AOR: 4.29, 95% CI: 2.31–6.15), and undergoing invasive procedures (AOR: 3.58, 95% CI: 1.11–7.52) increase the odds of acquiring healthcare-associated infections.

Conclusion

The cumulative prevalence of healthcare-associated infections in this study was comparable with similar studies conducted in developing countries. Cigarette smoking, staying in the hospital for more than 4 days, and undergoing invasive procedures increase the odds of healthcare-associated infections. These factors should be considered in the infection prevention and control program of the hospital.

Magnitude of surgical site infection and its associated factors among patients who underwent a surgical procedure at Wolaita Sodo University Teaching and Referral Hospital, South Ethiopia

Introduction

Surgical site infections are infections that take place within 30 days of an operative procedure. Worldwide, 23% of patients develop surgical site infections among all surgeries annually with the worst complications causing prolonged hospital stays, increased resistance of microorganisms to antimicrobials, higher health system costs, emotional stress for patients and their families, and substantial economic burdens on hospitals. Therefore, this study was created to assess the magnitude and associated factors of surgical site infection at Wolaita Sodo University Teaching and Referral Hospital.

Method

We conducted a hospital-based cross-sectional study on patients who underwent a surgical procedure in 2018 at Wolaita Sodo University Teaching and Referral Hospital. We applied a systematic random sampling technique to obtain 261 patient records from all records of surgical patients from January 1, 2018, to December 30, 2018. We collected data using a pretested checklist. We used bivariate and multivariate logistic regression analysis to identify factors associated with surgical site infection. We considered a P-value < 0.05 as statistically significant. Summary measures, texts, tables, and figures present the results of the analysis.

Result

Among the 261 patients, 34 or 13% (95% CI = 9.2%, 17.2%) developed surgical site infection. Patients younger than 40 years old [AOR 6.45; 95% CI (1.56, 26.67)], illiterate [AOR 4.25; 95% CI (1.52, 11.84)], with a history of previous hospitalization [AOR 4.50; 95% CI (1.44, 14.08)], with a prolonged preoperative hospital stay (≥ 7 days) [AOR 3.88; 95% CI (1.46, 10.29)], and admitted to the public wing of the ward [AOR 0.24; 95% CI (0.07, 0.79)] possessed factors associated with surgical site infection.

Conclusion

The magnitude of surgical site infection in this study was high. Shortening preoperative hospital stays, delivering intravenous antimicrobial prophylaxis before surgery, and giving wound care as ordered would significantly reduce the incidence of surgical site infection.

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.

The prevalence and root causes of surgical site infections in public versus private hospitals in Ethiopia: a retrospective observational cohort study

Background

Healthcare-associated illnesses, of which surgical site infection is the most common are significant causes of morbidity and mortality. Therefore, this study aimed to determine the prevalence and root causes of surgical site infections in public versus private hospitals in Ethiopia.

Methods

An institution based retrospective observational cohort study was conducted among patients who underwent surgical procedures at public and private health facilities from March 15 to April 15, 2018. Samples were selected by the simple random sampling technique, and data extracted from the patient’s medical chart, operation, and anesthesia notes. Data were entered using Epi info version 7 and analyzed using STATA 14. Binary logistic regression was fitted to identify factors associated with surgical site infections in private and public hospitals. Crude and adjusted odds ratios (OR) with a 95% confidence interval (CI) were computed to assess the strength of associations. Variables with a p-value less than 0.05 in the multivariable logistic regression model considered as significant predictors of surgical site infections.

Result

The overall prevalence of surgical site infections was 9.9% (95%CI: 7.8, 12.5). The prevalence of the infections was higher in procedures performed in public hospitals (13.4%) compared to private hospitals (6.5%). Rural residence (AOR = 0.13, 95%CI: 0.034 0.55), clean-contaminated and dirty wound (AOR = 12.81, 95%CI: 4.42 37.08) were significant predictors of the infections in private hospitals. Similarly, clean-contaminated and dirty wounds (AOR = 4.37, 95%CI: 1.88 10.14), length of hospital stay≥6 days (AOR = 2.86, 95%CI: 1.11 7.33), and surgical operation time of over 1 h (AOR = 15.24, 95%CI: 4.48 51.83) were such factors in public hospitals.

Conclusion

The prevalence of surgical site infections was high, and significant differences were also observed between public and private hospitals. Clean-contaminated and dirty wounds, prolonged operation, and length of hospital stay were predictors of surgical site infections among patients in public hospitals, whereas clean-contaminated wound and rural dwellings were predicted the infections among patients operated in the private hospital.
