Background
Little is known about perioperative mortality in sub-Saharan Africa. The perioperative mortality rate (POMR) and associated factors at a major referral hospital in Rwanda were measured.
Methods
The operative activity at University Teaching Hospital of Kigali was evaluated through an operative database. As a part of this larger study, patient characteristics and outcomes were measured to determine areas for improvement in patient care. Data were collected on patient demographics, surgeon, diagnosis, and operation over a 12-month period. The primary outcome was POMR. Secondary outcomes were timing and hospital location of death.
Results
The POMR was 6 %. POMR in patients under 5 years of age was 10 %, 3 % in patients 5–14 years and 6 % in patients age >14 years. For emergency and elective operations, POMR was 9 and 2 %, respectively. POMR was associated with emergency status, congenital anomalies, repeat operations, referral outside Kigali, and female gender. Orthopedic procedures and age 5–14 years were associated with decreased odds of mortality. Forty-nine percent of deaths occurred in the post-operative recovery room and 35 % of deaths occurred within the first post-operative day.
Conclusions
The POMR at a large referral hospital in Rwanda is <10 % demonstrating that surgery can save lives even in resource-limited settings. Emergency operations are associated with higher mortality, which could potentially be improved with faster identification and transfer from district hospitals. Nearly half of deaths occurred in the post-operative recovery room. Multidisciplinary audits of operative mortalities could help guide improvements in surgical care.

Resistance among bacterial infections is increasingly well-documented in high-income countries; however, relatively little is known about bacterial antimicrobial resistance in low-income countries, where the burden of infections is high.
We prospectively screened all adult inpatients at a referral hospital in Rwanda for suspected infection for seven months. Blood, urine, wound and sputum samples were cultured and tested for antibiotic susceptibility. We examined factors associated with resistance and compared hospital outcomes for participants with and without resistant isolates.
We screened 19,178 patient-days, and enrolled 647 unique participants with suspected infection. We obtained 942 culture specimens, of which 357 were culture-positive specimens. Of these positive specimens, 155 (43.4%) were wound, 83 (23.2%) urine, 64 (17.9%) blood, and 55 (15.4%) sputum. Gram-negative bacteria comprised 323 (88.7%) of all isolates. Of 241 Gram-negative isolates tested for ceftriaxone, 183 (75.9%) were resistant. Of 92 Gram-negative isolates tested for the extended spectrum beta-lactamase (ESBL) positive phenotype, 66 (71.7%) were ESBL positive phenotype. Transfer from another facility, recent surgery or antibiotic exposure, and hospital-acquired infection were each associated with resistance. Mortality was 19.6% for all enrolled participants.
This is the first published prospective hospital-wide antibiogram of multiple specimen types from East Africa with ESBL testing. Our study suggests that low-resource settings with limited and inconsistent access to the full range of antibiotic classes may bear the highest burden of resistant infections. Hospital-acquired infections and recent antibiotic exposure are associated with a high proportion of resistant infections. Efforts to slow the development of resistance and supply effective antibiotics are urgently needed.

Background
The purpose of this observational study is to characterize the use of social media content pertaining to global surgery.
Methods
A search for public posts on social media related to global surgery was performed over a 3-month window, from January 1st, 2019, to March 31st, 2019. Two public domains were included in the search: Instagram and Twitter. Posts were selected by filtering for one hashtag: #GlobalSurgery. A binary scoring system was used for media format, perspective of the poster, timing of the post, tone, and post content. Data were analyzed using Chi-squared tests with significance set to
p
< 0.05.
Results
Overall, 2633 posts with the hashtag #GlobalSurgery were publicly shared on these two social media platforms over the 3-month period. Of these, 2272 (86.3%) referenced content related to global surgery and were original posts. Physicians and other health professionals authored a majority (60.5%, 1083/1788) of posts on Twitter, whereas organizations comprised a majority of the posts on Instagram (59.9%, 290/484). Posts either had a positive (50.2%, 1140/2272) or neutral (49.6%, 1126/2272) tone, with only 0.3% or 6/2272 of posts being explicitly negative. The content of the posts varied, but most frequently (43.4%, 986/2272) focused on promoting communication and engagement within the community, followed by educational content (21.3%, 486/2272), advertisements (18.8%, 427/2272), and published research (13.2%, 299/2272). The majority of global surgery posts originated from the USA, UK, or Canada (67.6%, 1537/2272), followed by international organizations (11.5%, 261/2272). Chi-squared analysis comparing Instagram with Twitter performed examining media content, tone, perspective, and content, finding statistically significant differences (
p
< 0.001) the two platforms for each of the categories.
Conclusion
The online social media community with respect to global surgery engagement is predominantly composed of surgeons and health care professionals, focused primarily on promoting dialogue within the online community. Social media platforms may provide a scalable tool that can augment engagement between global surgeons, with remaining opportunity to foster global collaboration, community engagement, education and awareness.

Pediatric intestinal obstruction: analysis of etiologies and factors influencing short-term outcomes in Rwanda
2022
BackgroundIntestinal obstruction is a common presentation in pediatric surgical emergencies and presents with different etiologies depending on country or region. Its morbidity and mortality are high in low-income and middle-income countries, with variable influencing factors. The aims of this study were to determine the etiologies, morbidity and mortality of pediatric intestinal obstruction and to assess the factors associated with the outcomes of these conditions in Rwanda.MethodsThis was a cross-sectional study conducted on pediatric patients with intestinal obstruction in two Rwandan university teaching hospitals. The patients were followed from admission until discharge, and we documented their basic characteristics, diagnosis, operative details and postoperative outcomes. Data were collected using data collection form and were electronically captured and analysed using SPSS software.ResultsA total of 65 patients were enrolled in this study. They were predominantly male (n=49, 75.4%), and the majority of patients (86.2%) were below age 6 years. Intussusception was the most common etiology (n=22, 33.8%). Other common etiologies were Hirschsprung’s disease (n=13, 20%), incarcerated inguinal and umbilical hernias (n=6, 9.2%), intestinal worms’ impaction (n=5, 7.7%) and adhesions (n=5, 7.7%). Mortality and morbidity were 9.2% and 39.7%, respectively. The most common complications were surgical site infection (n=6, 9.5%) and sepsis (n=6, 9.5%). Preoperative anemia (p=0.001), finding of gangrenous bowels (p=0.003) and bowel resection at the time of laparotomy (p=0.039) were factors associated with postoperative complications.ConclusionsThe etiologies of intestinal obstruction are variable and common in children below 6 years in Rwanda. The associated morbidly is high and is influenced by the preoperative anemia, finding of gangrenous bowels and bowel resection.

RationaleMortality prediction scores are increasingly being evaluated in low and middle income countries (LMICs) for research comparisons, quality improvement and clinical decision-making. The modified early warning score (MEWS), quick Sequential (Sepsis-Related) Organ Failure Assessment (qSOFA), and Universal Vital Assessment (UVA) score use variables that are feasible to obtain, and have demonstrated potential to predict mortality in LMIC cohorts.ObjectiveTo determine the predictive capacity of adapted MEWS, qSOFA and UVA in a Rwandan hospital.Design, setting, participants and outcome measuresWe prospectively collected data on all adult patients admitted to a tertiary hospital in Rwanda with suspected infection over 7 months. We calculated an adapted MEWS, qSOFA and UVA score for each participant. The predictive capacity of each score was assessed including sensitivity, specificity, positive and negative predictive value, OR, area under the receiver operating curve (AUROC) and performance by underlying risk quartile.ResultsWe screened 19 178 patient days, and enrolled 647 unique patients. Median age was 35 years, and in-hospital mortality was 18.1%. The proportion of data missing for each variable ranged from 0% to 11.7%. The sensitivities and specificities of the scores were: adapted MEWS >4, 50.4% and 74.9%, respectively; qSOFA >2, 24.8% and 90.4%, respectively; and UVA >4, 28.2% and 91.1%, respectively. The scores as continuous variables demonstrated the following AUROCs: adapted MEWS 0.69 (95% CI 0.64 to 0.74), qSOFA 0.65 (95% CI 0.60 to 0.70), and UVA 0.71 (95% CI 0.66 to 0.76); there was no statistically significant difference between the discriminative capacities of the scores.ConclusionThree scores demonstrated a modest ability to predict mortality in a prospective study of inpatients with suspected infection at a Rwandan tertiary hospital. Careful consideration must be given to their adequacy before using them in research comparisons, quality improvement or clinical decision-making.

Effectiveness of intraoperative peritoneal lavage with saline in patient with intra-abdominal infections: a systematic review and meta-analysis
2023
Background
Intraoperative peritoneal lavage (IOPL) with saline has been widely used in surgical practice. However, the effectiveness of IOPL with saline in patients with intra-abdominal infections (IAIs) remains controversial. This study aims to systematically review randomized controlled trials (RCTs) evaluating the effectiveness of IOPL in patients with IAIs.
Methods
The databases of PubMed, Embase, Web of Science, Cochrane library, CNKI, WanFang, and CBM databases were searched from inception to December 31, 2022. Random-effects models were used to calculate the risk ratio (RR), mean difference, and standardized mean difference. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) was used to rate the quality of the evidence.
Results
Ten RCTs with 1318 participants were included, of which eight studies on appendicitis and two studies on peritonitis. Moderate-quality evidence showed that the use of IOPL with saline was not associated with a reduced risk of mortality (0% vs. 1.1%; RR, 0.31 [95% CI, 0.02–6.39]), intra-abdominal abscess (12.3% vs. 11.8%; RR, 1.02 [95% CI, 0.70–1.48];

I

I

= 0%) in patients with peritonitis when compared to non-IOPL.
Conclusion
IOPL with saline use in patients with appendicitis was not associated with significantly decreased risk of mortality, intra-abdominal abscess, incisional surgical site infection, postoperative complication, reoperation, and readmission compared with non-IOPL. These findings do not support the routine use of IOPL with saline in patients with appendicitis. The benefits of IOPL for IAI caused by other types of abdominal infections need to be investigated.

ObjectivesTo analyse the past 30-year trends in mortality and morbidity of interpersonal violence against children, its demographic distribution and correlation with specific risk factors.DesignEcological study at the country and regional level.Setting46 countries and 4 subregions of sub-Saharan Africa (SSA): Central, Eastern, Southern and Western.ParticipantsChildren aged 0–19 years old.Primary and secondary outcome measuresTrends in mortality rates and disability-adjusted life-years (DALYs) attributed to interpersonal violence injuries in children; correlation between socio-demographic index (SDI)/alcohol consumption per capita and child interpersonal violence.ResultsDeaths and DALYs per 100 000 population from child violence-related injuries in SSA declined from 4.0 (95% uncertainty interval (UI): 3.3–4.9) to 3.1 (95% UI: 2.3 to 3.9) and 334.9 (95% UI: 276.4 to 407.7) to 260.3 (95% UI: 197.9 to 321.9) respectively from 1990 to 2019 (reductions of 22.5% and 22.3%). Southern SSA had the highest deaths/DALYs rates for each type of physical violence (sharp object/firearm/other) and Central SSA for sexual violence. Alcohol consumption correlated significantly with deaths and DALYs, but SDI showed a non-significant correlation.ConclusionsRates of child interpersonal violence deaths and DALYs decreased from 2009 to 2019 in SSA, driven by remarkable decreases in the Southern subregion. Understanding the determinants of these downward trends and implementation of policies targeting known risk factors like alcohol consumption may pave the way for enhanced child safety protection. Further curbing the disparities between countries and subregions necessitates long-term commitment to evidence-based action plans.

Introduction
Peptic ulcer disease is a significant cause of morbidity and mortality worldwide, with a significant burden in low- and middle-income countries. However, there is limited information regarding management of peptic ulcer disease in these countries. This study describes surgical interventions for peptic ulcer disease in sub-Saharan Africa.
Materials and Methods
A systematic review was performed using PubMed, EMBASE, and African Index Medicus for studies describing surgical management of peptic ulcer disease in sub-Saharan Africa.
Results
From 55 published reports, 6594 patients underwent surgery for peptic ulcer disease. Most ulcers (86 %) were duodenal with the remainder gastric (14 %). Thirty-five percent of operations were performed for perforation, 7 % for bleeding, 30 % for obstruction, and 28 % for chronic disease. Common operations included vagotomy (60 %) and primary repair (31 %). The overall case fatality rate for peptic ulcer disease was 5.7 % and varied with indication for operation: 13.6 % for perforation, 11.5 % for bleeding, 0.5 % for obstruction, and 0.3 % for chronic disease.
Conclusion
Peptic ulcer disease remains a significant indication for surgery in sub-Saharan Africa. Recognizing the continued role of surgery for peptic ulcer disease in sub-Saharan Africa is important for strengthening surgical training programs and optimizing allocation of resources.

Surgical site infections (SSIs) are the most common adverse event occurring in surgical patients. Optimal prevention of SSIs requires the bundled integration of a variety of measures before, during, and after surgery. Surgical antibiotic prophylaxis (SAP) is an effective measure for preventing SSIs. It aims to counteract the inevitable introduction of bacteria that colonize skin or mucosa into the surgical site during the intervention. This document aims to guide surgeons in appropriate administration of SAP by addressing six key questions. The expert panel identifies a list of principles in response to these questions that every surgeon around the world should always respect in administering SAP.

In the multimodal strategy context, to implement healthcare-associated infection prevention, bundles are one of the most commonly used methods to adapt guidelines in the local context and transfer best practices into routine clinical care. One of the most important measures to prevent surgical site infections is surgical antibiotic prophylaxis (SAP). This narrative review aims to present a bundle for the correct SAP administration and evaluate the evidence supporting it. Surgical site infection (SSI) prevention guidelines published by the WHO, CDC, NICE, and SHEA/IDSA/APIC/AHA, and the clinical practice guidelines for SAP by ASHP/IDSA/SIS/SHEA, were reviewed. Subsequently, comprehensive searches were also conducted using the PubMed®/MEDLINE and Google Scholar databases, in order to identify further supporting evidence-based documentation. The bundle includes five different measures that may affect proper SAP administration. The measures included may be easily implemented in all hospitals worldwide and are based on minimal drug pharmacokinetics and pharmacodynamics knowledge, which all surgeons should know. Antibiotics for SAP should be prescribed for surgical procedures at high risk for SSIs, such as clean–contaminated and contaminated surgical procedures or for clean surgical procedures where SSIs, even if unlikely, may have devastating consequences, such as in procedures with prosthetic implants. SAP should generally be administered within 60 min before the surgical incision for most antibiotics (including cefazolin). SAP redosing is indicated for surgical procedures exceeding two antibiotic half-lives or for procedures significantly associated with blood loss. In principle, SAP should be discontinued after the surgical procedure. Hospital-based antimicrobial stewardship programmes can optimise the treatment of infections and reduce adverse events associated with antibiotics. In the context of a collaborative and interdisciplinary approach, it is essential to encourage an institutional safety culture in which surgeons are persuaded, rather than compelled, to respect antibiotic prescribing practices. In that context, the proposed bundle contains a set of evidence-based interventions for SAP administration. It is easy to apply, promotes collaboration, and includes measures that can be adequately followed and evaluated in all hospitals worldwide.
