Perioperative patient outcomes in the African Surgical Outcomes Study: a 7-day prospective observational cohort study

Family supplemented patient monitoring after surgery (SMARTER): a pilot stepped-wedge cluster-randomised trial

BACKGROUND

Mortality after surgery in Africa is twice that in high-income countries. Most deaths occur on wards after patients develop postoperative complications. Family members might contribute meaningfully and safely to early recognition of deteriorating patients.

METHODS

This was a stepped-wedge cluster-randomised trial of an intervention training family members to support nursing staff to take and record patient vital signs every 4 h after surgery. Adult inpatients across four surgical wards (clusters) in a Ugandan hospital were included. Clusters crossed once from routine care to the SMARTER intervention at monthly intervals. The primary outcome was frequency of vital sign measurements from arrival on the postoperative ward to the end of the third postoperative day (3 days).

RESULTS

We enrolled 1395 patients between April and October 2021. Mean age was 28.2 (range 5-89) yr; 85.7% were female. The most common surgical procedure was Caesarean delivery (74.8%). Median (interquartile range) number of sets of vital signs increased from 0 (0-1) in control wards to 3 (1-8) in intervention wards (incident rate ratio 12.4, 95% confidence interval [CI] 8.8-17.5, P<0.001). Mortality was 6/718 (0.84%) patients in the usual care group vs 12/677 (1.77%) in the intervention group (odds ratio 1.32, 95% CI 0.1-14.7, P=0.821). There was no difference in length of hospital stay between groups (usual care: 2 [2-3] days vs intervention: 2 [2-4] days; hazard ratio 1.11, 95% CI 0.84-1.47, P=0.44).

CONCLUSIONS

Family member supplemented vital signs monitoring substantially increased the frequency of vital signs after surgery. Care interventions involving family members have the potential to positively impact patient care.

Colombian surgical outcomes study insights on perioperative mortality rate, a main indicator of the lancet commission on global surgery - a prospective cohort study

Background

Surgical care holds significant importance in healthcare, especially in low and middle-income countries, as at least 50% of the 4.2 million deaths within the initial 30 days following surgery take place in these countries. The Lancet Commission on Global Surgery proposed six indicators to enhance surgical care. In Colombia, studies have been made using secondary data. However, strategies to reduce perioperative mortality have not been implemented. This study aims to describe the fourth indicator, perioperative mortality rate (POMR), with primary data in Colombia.

Methods

A multicentre prospective cohort study was conducted across 54 centres (hospitals) in Colombia. Each centre selected a 7-day recruitment period between 05/2022 and 01/2023. Inclusion criteria involved patients over 18 years of age undergoing surgical procedures in operating rooms. Data quality was ensured through a verification guideline and statistical analysis using mixed-effects multilevel modelling with a case mix analysis of mortality by procedure-related, patient-related, and hospital-related conditions.

Findings

3807 patients were included with a median age of 48 (IQR 32-64), 80.3% were classified as ASA I or II, and 27% of the procedures had a low-surgical complexity. Leading procedures were Orthopedics (19.2%) and Gynaecology/Obstetrics (17.7%). According to the Clavien-Dindo scale, postoperative complications were distributed in major complications (11.7%, 10.68-12.76) and any complication (31.6%, 30.09-33.07). POMR stood at 1.9% (1.48-2.37), with elective and emergency surgery mortalities at 0.7% (0.40-1.23) and 3% (2.3-3.89) respectively.

Interpretation

The POMR was higher than the ratio reported in previous national studies, even when patients had a low-risk profile and low-complexity procedures. The present research represents significant public health progress with valuable insights for national decision-makers to improve the quality of surgical care.

Surgical informed consent practices and influencing factors in sub-Saharan Africa: a scoping review of the literature

INTRODUCTION

Current international standards in consent to surgery practices are usually derived from health systems in Western countries, while little attention has been given to other contexts such as sub-Saharan Africa (SSA), despite this region facing the highest burdens of disease amenable to surgery globally. The aim of this study was to examine how the concept of informed consent for surgery is interpreted and applied in the context of SSA, and factors affecting current practices.

METHODS

A systematic search of Medline, Embase and African Journal OnLine databases as well as grey sources was executed in May 2023 to retrieve relevant literature published since 2010 in English language against a set of given criteria. The socioecological framework for health was used for organising and summarising the identified evidence.

RESULTS

A total of 27 papers were included in the review. Findings revealed that consent to surgery practices is generally substandard across SSA and the process is not adequate. Patients' understanding of informed consent is limited, likewise awareness of their rights to decision-making. A range of factors at the individual, interpersonal, institutional and system/societal levels affect the informed consent process.

CONCLUSION

There is a need to find more culturally acceptable and ethical ways to include the participation of patients in the decision-making process for surgical treatment in the SSA and define standards more closely aligned with the local context.

Microbiology testing capacity and antimicrobial drug resistance in surgical-site infections: a post-hoc, prospective, secondary analysis of the FALCON randomised trial in seven low-income and middle-income countries

BACKGROUND

Surgical-site infection (SSI) is one of the most common health-care-associated infections, substantially contributing to antibiotic use. Targeted antibiotic prophylaxis to prevent SSIs and effective treatment are crucial to controlling antimicrobial resistance (AMR). This study aimed to describe the testing capacity and multidrug resistance (MDR) of SSI microorganisms in low-income and middle-income countries (LMICs).

METHODS

This analysis included patients undergoing abdominal surgery in seven LMICs (Benin, Ghana, India, Mexico, Nigeria, Rwanda, and South Africa) as part of the FALCON randomised controlled trial. Wound swabs were collected from patients diagnosed with SSI, as per US Centers for Disease Control and Prevention (CDC) definition. Data on microorganism species and MDR, as per CDC and European Centre for Disease Prevention and Control definitions, were analysed alongside hospital-level data on local microbiological practices. An adjusted analysis was performed to identify perioperative factors associated with MDR. Testing capacity was assessed by the completion of swab testing in positively diagnosed SSIs.

FINDINGS

Between Dec 10, 2018, and Sept 7, 2020, 5788 patients were recruited to the FALCON trial. 1163 patients were diagnosed with an SSI, of whom 905 (77·8%) received prophylactic antibiotics before surgery. In patients with SSIs, 935 of 1163 (80·4%) did not have a wound swab; 195 were from hospitals not performing swabs (15 hospitals) and 740 were from hospitals with capacity but no swab performed (35 hospitals). Of 228 patients swabbed, 200 (88·5%) had microorganisms detected. Escherichia coli (89 of 200, 37·9%) was the most common microorganism and 116 of 200 (58·0%) patients were not covered by the perioperative prophylactic antibiotic. MDR was found in 102 of 147 (69·4%) patients for whom data were available to determine MDR status. Adjusted analysis found that appropriate prophylactic antibiotic coverage (adjusted odds ratio 0·43, 95% CI 0·19-0·96) and regular availability of infection control teams (0·32, 0·11-0·93) were associated with a significant reduction in MDR.

INTERPRETATION

Targeted perioperative antibiotic prophylaxis during contaminated abdominal surgery is insufficient in LMICs, with very few SSI organisms undergoing formal diagnosis. Expansion of testing capacity, development of local guidelines, and implementation of infection control teams could support the prevention of SSI through directed antibiotic prophylaxis, subsequently reducing the burden of MDR.

Mechanisms and causes of death after abdominal surgery in low-income and middle-income countries: a secondary analysis of the FALCON trial

BACKGROUND

Death after surgery is devasting for patients, families, and communities, but remains common in low-income and middle-income countries (LMICs). We aimed to use high-quality data from an existing global randomised trial to describe the causes and mechanisms of postoperative mortality in LMICs. To do so, we developed a novel framework, learning from both existing classification systems and emerging insights during data analysis.

METHODS

This study was a preplanned secondary analysis of the FALCON trial in 54 hospitals across seven LMICs (Benin, Ghana, India, Mexico, Nigeria, Rwanda, and South Africa). FALCON was a pragmatic, 2 × 2 factorial, randomised controlled trial that compared the effectiveness of two types of interventions for skin preparation (10% aqueous povidone-iodine vs 2% alcoholic chlorhexidine) and sutures (triclosan-coated vs uncoated). Patients who did not have surgery or were lost to follow-up were excluded (n=231). The primary outcomes of the present analysis were the mechanism and cause of death within 30-days of surgery, determined using a modified verbal autopsy strategy from serious adverse event reports. Factors associated with mortality were explored in a mixed-effects Cox proportional hazards model. The FALCON trial is registered with ClinicalTrials.gov, NCT03700749.

FINDINGS

This preplanned secondary analysis of the FALCON trial included 5558 patients who underwent abdominal surgery, of whom 4248 (76·4%) patients underwent surgery in tertiary, referral centres and 1310 (23·6%) underwent surgery in primary referral (ie, district or rural) hospitals. 3704 (66·7%) of 5558 surgeries were emergent. 306 (5·5%) of 5558 patients died within 30 days of surgery. 226 (74%) of 306 deaths were due to circulatory system failure, which included 173 (57%) deaths from sepsis and 29 (9%) deaths from hypovolaemic shock including bleeding. 47 (15%) deaths were due to respiratory failure. 60 (20%) of 306 patients died without a clear cause of death: 45 (15%) patients died with sepsis of unknown origin and 15 (5%) patients died of an unknown cause. 46 (15%) of 306 patients died within 24 h, 111 (36%) between 24 h and 72 h, 57 (19%) between >72 h and 168 h, and 92 (30%) more than 1 week after surgery. 248 (81%) of 306 patients died in hospital and 58 (19%) patients died out of hospital. The adjusted Cox regression model identified age (hazard ratio 1·01, 95% CI 1·01-1·02; p<0·0001), ASA grade III-V (4·93, 3·45-7·03; p<0·0001), presence of diabetes (1·47, 1·04-2·41; p=0·033), being an ex-smoker (1·59, 1·10-2·30; p=0·013), emergency surgery (2·08, 1·45-2·98; p<0·0001), cancer (1·98, 1·42-2·76; p<0·0001), and major surgery (3·94, 2·30-6·75; p<0·0001) as risk factors for postoperative mortality INTERPRETATION: Circulatory failure leads to most deaths after abdominal surgery, with sepsis accounting for almost two-thirds. Variability in timing of death highlights opportunities to intervene throughout the perioperative pathway, including after hospital discharge. A high proportion of patients without a clear cause of death reflects the need to improve capacity to rescue and cure by strengthening perioperative systems.

Orthopedic postoperative infection profile and antibiotic sensitivity of 2038 patients across 24 countries - Call for region and institution specific surgical antimicrobial prophylaxis

Purpose

Improper utilization of surgical antimicrobial prophylaxis frequently leads to increased risks of morbidity and mortality.This study aims to understand the common causative organism of postoperative orthopedic infection and document the surgical antimicrobial prophylaxis protocol across various institutions in to order to strengthen surgical antimicrobial prophylaxis practice and provide higher-quality surgical care.

Methods

This multicentric multinational retrospective study, includes 24 countries from five different regions (Asia Pacific, South Eastern Africa, Western Africa, Latin America, and Middle East). Patients who developed orthopedic surgical site infection between January 2021 and December 2022 were included. Demographic details, bacterial profile of surgical site infection, and antibiotic sensitivity pattern were documented.

Results

2038 patients from 24 countries were included. Among them 69.7 % were male patients and 64.1 % were between 20 and 60 years. 70.3 % patients underwent trauma surgery and instrumentation was used in 93.5 %. Ceftriaxone was the most common preferred in 53.4 %. Early SSI was seen in 55.2 % and deep SSI in 59.7 %. Western Africa (76 %) and Asia-Pacific (52.8 %) reported a higher number of gram-negative infections whereas gram-positive organisms were predominant in other regions. Most common gram positive organism was Staphylococcus aureus (35 %) and gram-negative was Klebsiella (17.2 %). Majority of the organisms showed variable sensitivity to broad-spectrum antibiotics.

Conclusion

Our study strongly proves that every institution has to analyse their surgical site infection microbiological profile and antibiotic sensitivity of the organisms and plan their surgical antimicrobial prophylaxis accordingly. This will help to decrease the rate of surgical site infection, prevent the emergence of multidrug resistance and reduce the economic burden of treatment.

Length of hospital stay and associated factors among adult surgical patients admitted to surgical wards in Amhara Regional State Comprehensive Specialized Hospitals, Ethiopia

INTRODUCTION

Hospitals across the country are facing increases in hospital length of stay ranging from 2% to 14%. This results in patients who stay in hospital for long periods of time being three times more likely to die in hospital. Therefore, identifying factors that contribute to longer hospital stays enhances the ability to improve services and quality of patient care. However, there is limited documented evidence on factors associated with longer hospital stays among surgical inpatients in Ethiopia and the study area.

OBJECTIVE

This study aimed to assess the length of hospital stay and associated factors among adult surgical patients admitted to surgical wards in Amhara Regional State Comprehensive Specialized Hospitals, Ethiopia, 2023.

METHODS

An institutional-based cross-sectional study was conducted among 452 adult surgical patients from April 17 to May 22, 2023. Data were collected based on a pretested, structured, interviewer-administered questionnaire, medical record review, and direct measurement of BMI. Study participants were selected using a systematic random sampling technique. The collected data were cleaned, entered into EpiData version 4.6.0 and exported to STATA version 14 for analysis. Binary logistic regression analysis was used. Variables with a p value <0.05 in the multivariable logistic regression analysis were considered statistically significant.

RESULTS

In the current study, the prevalence of prolonged hospital stay was 26.5% (95% CI: 22.7, 30.8). Patients referred from another public health facility (AOR = 2.65; 95% CI: 1.14, 6.14), hospital-acquired pneumonia (AOR = 3.64; 95% CI: 1.43, 9.23), duration of surgery ≥110 minutes (AOR = 2.54; 95% CI: 1.25, 5.16), being underweight (AOR = 5.21; 95%CI: 2.63, 10.33) and preoperative anemia (AOR = 3.22; 95% CI: 1.77, 5.86) were factors associated with prolonged hospital stays.

CONCLUSION

This study found a significant proportion of prolonged hospital stays among patients admitted to surgical wards. Patients referred from another public health facility, preoperative anemia, underweight, duration of surgery ≥110 minutes, and hospital-acquired pneumonia were factors associated with prolonged hospital stay. Early screening and treatment of anemia and malnutrition before surgery can shorten the length of stay.

Perioperative antithrombotic medication: An approach for the primary care clinician

The primary care clinician faces many challenges and is often left to manage complex pathology because of resource constraints at higher levels of care. One of these complex conditions is the perioperative management of antithrombotic medication. This narrative review is focused on helping the clinician navigate the complex path and multiple guidelines related to the perioperative use of antithrombotic medication. Perioperative antithrombotic guidelines (American College of Chest Physicians, European Society of Regional Anaesthesia, and American Society of Regional Anesthesia) and relevant publications were identified by a PubMed search using the terms perioperative AND anticoagulants OR antithrombotics AND guideline. Issues relevant to clinical practice were identified, and attempts were made to explain any ambiguity that arose. Adhering to basic pharmacological principles and evidence-based guidelines allows for the safe usage of antithrombotics. Knowing when to stop, continue, bridge and restart antithrombotic medication prevents perioperative morbidity and mortality. Stopping antithrombotic medication too early can lead to thromboembolic complications associated with their primary disease process. Not stopping antithrombotic medication or stopping it too late can potentially cause life-threatening bleeding, haematomas and increased transfusion requirements.

Risk factors associated with surgical site infection following orthopaedic surgery in South Africa and Sub-Saharan Africa: a scoping review protocol

OBJECTIVE

The objective of the scoping review will be to understand and describe risk factors associated with surgical site infection (SSI) in an orthopaedic surgery population in Sub-Saharan Africa and South Africa. This paper describes the protocol that will be used for the scoping review.

METHOD

A comprehensive literature search will be conducted using MEDLINE (PubMed), CINAHL (EBSCO), Embase and Cochrane Libraries to identify articles meeting the inclusion criteria, including both published and grey literature, in order to provide a broad overview of the reported risk factors associated with patients who have undergone an orthopaedic surgery with an outcome of SSI within 90 days of a procedure. Additional studies will be sourced by exploring the reference list of included eligible studies. By using a combination of the Population, Exposure, Outcome framework, terms and synonyms related to each category, in different variations, along with Boolean operators (AND, OR, NOT) in the search strategy, identified comprehensive and relevant literature for the scoping review.

RESULTS

It is anticipated the results will provide a baseline of risk factors that will inform the development of a risk assessment tool for clinical use.

CONCLUSION

This protocol will inform the development of a scoping review to describe factors associated with SSIs following orthopaedic surgery in Sub-Saharan Africa and South Africa.

Strategies to prevent blood loss and reduce transfusion in emergency general surgery, WSES-AAST consensus paper

Emergency general surgeons often provide care to severely ill patients requiring surgical interventions and intensive support. One of the primary drivers of morbidity and mortality is perioperative bleeding. In general, when addressing life threatening haemorrhage, blood transfusion can become an essential part of overall resuscitation. However, under all circumstances, indications for blood transfusion must be accurately evaluated. When patients decline blood transfusions, regardless of the reason, surgeons should aim to provide optimal care and respect and accommodate each patient's values and target the best outcome possible given the patient's desires and his/her clinical condition. The aim of this position paper was to perform a review of the existing literature and to provide comprehensive recommendations on organizational, surgical, anaesthetic, and haemostatic strategies that can be used to provide optimal peri-operative blood management, reduce, or avoid blood transfusions and ultimately improve patient outcomes.

Perioperative capacity and contextual challenges in teaching hospitals of southern Ethiopia: explanatory sequential mixed-methods research

BACKGROUND

Previous Ethiopian literature on surgical capacity and challenges has focused on quantitative investigations, lacking contextual understanding. This explanatory sequential mixed-methods research (MMR) aimed to assess perioperative capacity and contextual challenges at three teaching hospitals in southern Ethiopia.

METHODS

A quantitative survey assessed workforce, infrastructure, service delivery, financing, and information systems. The survey findings were explained by qualitative semi-structured interviews of twenty perioperative providers. Descriptive statistics were integrated with qualitative thematic analysis findings using the narrative waving approach. Key findings from both datasets were linked using a joint display table.

RESULTS

The survey revealed shortages in the specialist workforce (with a ratio of 0.58 per 100,000 population), surgical volume (at 115 surgeries per 100,000 population), equipment, supplies, financing, and perioperative data tracking. Hospitals' radiology services and blood products were only available 25-50% of the time, while anesthetic agents and essential laboratory services were often available 51-75% of the time. Perioperative management protocols were used rarely (1-25% of the time). Over 90% of patients lack health insurance coverage. Qualitative data also revealed scarcity of perioperative resources and equipment; unaffordable perioperative costs, lack of health insurance coverage, and unforeseen expenses; poor patient safety culture and communication barriers across the perioperative continuum of care; workforce shortages, job dissatisfaction, and concerns of competence; and weak national governance, and sociopolitical turmoil, and global market volatility exacerbating local challenges. These challenges are linked to risks in quality of care and patient safety, according to clinicians.

CONCLUSION

The study identifies deficiencies in the health system and sociopolitical landscape affecting safe surgery conduct. It highlights the need for comprehensive health system strengthening to expand workforce, upgrade facilities, improve safety culture, resilience, and leadership to ensure timely access to essential surgery. Exploring external factors, such as the impact of national governance and sociopolitical stability on reform efforts is also essential.

Gender-Affirming Surgery in Low- and Middle-Income Countries: A Systematic Review

Objectives: Fewer than one-fifth of all studies on gender-affirming care originate from low- and middle-income countries (LMICs). This is the first systematic review to examine surgical demographics and outcomes following gender-affirming surgery (GAS) in LMICs. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, five databases were systematically searched for original studies and case series on GAS within LMIC settings. Excluded reports included animal studies, non-English language studies, secondary studies including reviews, individual case reports and conference abstracts. Results: This review includes 34 studies involving n = 5064 TGNB individuals. Most studies (22, 64.7%) were from upper-middle-income countries, followed by lower-middle-income countries (12, 35.3%). A total of 31 studies (91.2%) reported on post-operative outcomes. Of n = 5013 patients who underwent GAS, 71.5% (n = 3584) underwent masculinizing and 29.5% (n = 1480) underwent feminizing procedures. The predominant procedures were metoidioplasty (n = 2270/3584, 63.3%) and vaginoplasty (n = 1103/1480, 74.5%). Mean follow-up was 47.7 months. In patients who underwent metoidioplasty, 6.8% (n = 155) of patients experienced a complication and 6.3% (n = 144) underwent revision surgery. In patients who underwent vaginoplasty, 11.5% (n = 127) of patients experienced a complication and 8.5% (n = 94) underwent revision surgery. Of the studies (25/34, 73.5%) that reported on quality of life and post-operative satisfaction, the majority showed marked improvements in psychosocial and functional outcomes. Notably, no post-surgical regret was reported among the surveyed patients. Conclusions: Existing literature on GAS in LMICs remains scarce and is concentrated in select institutions that drive specific procedures. Our review highlights the low reported volumes of GAS, variability in surgical outcomes and quality of life.

Method of Anesthesia and Perioperative Risk Factors, Maternal Anesthesia Complications, and Neonatal Mortality Following Cesarean Delivery in Africa: A Substudy of a 7-Day Prospective Observational Cohort Study

BACKGROUND

The African Surgical Outcomes Study (ASOS) found that maternal mortality following cesarean delivery in Africa is 50 times higher than in high-income countries, and associated with obstetric hemorrhage and anesthesia complications. Mothers who died were more likely to receive general anesthesia (GA). The associations between GA versus spinal anesthesia (SA) and preoperative risk factors, maternal anesthesia complications, and neonatal outcomes following cesarean delivery in Africa are unknown.

METHODS

This is a secondary explanatory analysis of 3792 patients undergoing cesarean delivery in ASOS, a prospective observational cohort study, across 22 African countries. The primary aim was to estimate the association between preoperative risk factors and the outcome of the method of anesthesia delivered. Secondary aims were to estimate the association between the method of anesthesia and the outcomes (1) maternal intraoperative hypotension, (2) severe maternal anesthesia complications, and (3) neonatal mortality. Generalized linear mixed models adjusting for obstetric gravidity and gestation, American Society of Anesthesiologists (ASA) category, urgency of surgery, maternal comorbidities, fetal distress, and level of anesthesia provider were used.

RESULTS

Of 3709 patients, SA was performed in 2968 (80%) and GA in 741 (20%). Preoperative factors independently associated with GA for cesarean delivery were gestational age (adjusted odds ratio [aOR], 1.093; 95% confidence interval [CI], 1.052-1.135), ASA categories III (aOR, 11.84; 95% CI, 2.93-46.31) and IV (aOR, 11.48; 95% CI, 2.93-44.93), eclampsia (aOR, 3.92; 95% CI, 2.18-7.06), placental abruption (aOR, 6.23; 95% CI, 3.36-11.54), and ruptured uterus (aOR, 3.61; 95% CI, 1.36-9.63). SA was administered to 48 of 94 (51.1%) patients with eclampsia, 12 of 28 (42.9%) with cardiac disease, 14 of 19 (73.7%) with preoperative sepsis, 48 of 76 (63.2%) with antepartum hemorrhage, 30 of 55 (54.5%) with placenta previa, 33 of 78 (42.3%) with placental abruption, and 12 of 29 (41.4%) with a ruptured uterus. The composite maternal outcome "all anesthesia complications" was more frequent in GA than SA (9/741 [1.2%] vs 3/2968 [0.1%], P < .001). The unadjusted neonatal mortality was higher with GA than SA (65/662 [9.8%] vs 73/2669 [2.7%], P < .001). The adjusted analyses demonstrated no association between method of anesthesia and (1) intraoperative maternal hypotension and (2) neonatal mortality.

CONCLUSIONS

Analysis of patients undergoing anesthesia for cesarean delivery in Africa indicated patients more likely to receive GA. Anesthesia complications and neonatal mortality were more frequent following GA. SA was often administered to high-risk patients, including those with eclampsia or obstetric hemorrhage. Training in the principles of selection of method of anesthesia, and the skills of safe GA and neonatal resuscitation, is recommended.

Updates in global oncology: Advancements and future directions

Globally, cancer is the second leading cause of death, and low- and middle-income countries bear most of the disease burden. While cancer is increasingly recognized as a major global health issue, more work remains. Understanding the status of global cancer care will shape the next steps in ensuring equitable global access to cancer care. This article highlights ongoing initiatives in global oncology and the next steps in advancing the field.

Gastrointestinal Surgical Outcomes Study (GISOS): a 30-day monocentric prospective cohort study in Ethiopia

OBJECTIVE

The impact of perioperative mortality and morbidity extends globally, playing substantial roles in mortality rates, levels of disability and economic consequences. This study was primarily designed to provide insights into the surgical outcomes of gastrointestinal surgeries carried out in a high-volume centre in Ethiopia in the year 2023.

DESIGN

A 30-day prospective cohort observational study employed.

SETTING

High volume surgical specialised hospital in Ethiopia.

PARTICIPANTS

All adult patients who had abdominal surgery.

OUTCOME MEASURES

30th-day postoperative mortality and complications.

RESULTS

During this prospective observational study, data from 259 patients were collected. This prospective observational study found that 30-day complication rate was 30.5%. Surgical site infection is the leading complications (15.8%) followed by postop acute kidney injury (9.3%). Malignant pathology (adjusted OR (AOR)=1.43 (1.01 to 3.06); p=0.035, ASA III (AOR=4.00 (1.01 to 16.5); p=0.049), ECOG III (AOR=2.8 (1.55 to 7.30); p=0.025) and comorbidity (AOR=2.02 (1.02 to 3.18); p=0.008) had statistically significant association with 30-day complication rates. We also found that a 30-day mortality rate was 14.3%. Emergency surgery (AOR=5.53 (1.4 to 21.6); p=0.014), Eastern Cooperative Oncology Group III (AOR=8.6 (1.01 to 74.1); p=0.0499), American Society of Anesthesiology III (AOR=12.7 (1.9 to 85.5); p=0.009) and comorbidity (AOR=7.5 (1.4 to 39.1); p=0.017) had statistical significance association with a 30-day mortality rate after gastrointestinal surgery.

CONCLUSION

The findings of this study indicated that postoperative mortality and complications were alarmingly high, which highlights the need for innovative solutions to lower postoperative mortality and complications.

Perioperative Anesthesia-Related Complications and Risk Factors in Children: A Cross-Sectional Observation Study in Rwanda

BACKGROUND

Despite an increasing awareness of the unmet burden of surgical conditions, information on perioperative complications in children remains limited especially in low-income countries such as Rwanda. The objective of this study was to estimate the prevalence of perioperative anesthesia-related adverse events and to explore potential risk factors associated with them among pediatric surgical patients in public referral hospitals in Rwanda.

METHODS

Data were collected for all patients under 5 years of age undergoing surgery in 3 public referral hospitals in Rwanda from June to December 2015. Patient and family history, type of surgery, comorbidities, anesthesia technique, intraoperative adverse events and postoperative events in the postanesthesia care unit (PACU) were recorded. The incidence of perioperative adverse events was assessed and associated risk factors analyzed with univariate logistic regression.

RESULTS

Of 354 patients enrolled in this study 11 children had a cardiac arrest. Six (1.7%) suffered an intraoperative cardiac arrest, 2 of whom (0.6%) died intraoperatively. In the PACU, 6 (1.8%) suffered a postoperative cardiac arrest, 5 of whom (1.5%) died in the PACU. One child had both an intraoperative cardiac arrest and then a cardiac arrest in PACU but survived. Eighty-nine children (25.1%) had an intraoperative adverse event, whereas 67 (20.6%) had an adverse event in PACU. A review of the cases where cardiac arrest or death occurred indicated that there were significant lapses in the expected standard of care. Age <1 week was associated with cardiac arrest or death.

CONCLUSIONS

The rate of perioperative complications, including death, for children undergoing surgery in tertiary care hospitals in Rwanda was high. Quality improvement measures are needed to decrease this rate among surgical pediatric patients in this low resource setting.

Perioperative mortality rate and its predictors after emergency laparatomy at Debre Markos comprehensive specialized hospital, Northwest Ethiopia: 2023: retrospective follow-up study

BACKGROUND

Emergency laparatomy is abdominal surgery associated with a high rate of mortality. There are few reports on rates and predictors of postoperative mortality, whereas disease related or time specific studies are limited. Understanding the rate and predictors of mortality in the first 30 days (perioperative period) is important for evidence based decision and counseling of patients. This study aimed to estimate the perioperative mortality rate and its predictors after emergency laparatomy at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia, 2023.

METHODS

This was a Hospital-based retrospective follow-up study conducted at Debre Markos Comprehensive Specialized Hospital in Ethiopia among patients who had undergone emergency laparatomy between January 1, 2019 and December 31, 2022. Sample of 418 emergency laparatomy patients selected with simple random sampling technique were studied. The data were extracted from March 15, 2023 to April 1, 2023 using a data extraction tool, cleaned, and entered into Epi-Data software version 3.1 before being exported to STATA software version 14.1 for analysis. Predictor variables with P value < 0.05 in multivariable Cox regression were reported.

RESULTS

Data of 386 study participants (92.3% complete charts) were analyzed. The median survival time was 18 days [IQR: (14, 29)]. The overall perioperative mortality rate in the cohort during the 2978 person-days of observations was 25.5 per 1000 person-days of follow-up [95% CI: (20.4, 30.9))]. Preoperative need for vasopressor [AHR: 1.8 (95% CI: (1.11, 2.98))], admission to intensive care unit [AHR: 2.0 (95% CI: (1.23, 3.49))], longer than three days of symptoms [AHR: 2.2 (95% CI: (1.15, 4.02))] and preoperative sepsis [AHR: 1.8 (95% CI: (1.05, 3.17))] were identified statistically significant predictors of perioperative mortality after emergency laparatomy.

CONCLUSIONS

The perioperative mortality rate is high. Preoperative need for vasopressors, admission to intensive care unit, longer than three days of symptoms and preoperative sepsis were predictors of increased perioperative mortality rate.

Outcomes after surgery for children in Africa (ASOS-Paeds): a 14-day prospective observational cohort study

BACKGROUND

Safe anaesthesia and surgery are a public health imperative. There are few data describing outcomes for children undergoing anaesthesia and surgery in Africa. We aimed to get robust epidemiological data to describe patient care and outcomes for children undergoing anaesthesia and surgery in hospitals in Africa.

METHODS

This study was a 14-day, international, prospective, observational cohort study of children (aged <18 years) undergoing surgery in Africa. We recruited as many hospitals as possible across all levels of care (first, second, and third) providing surgical treatment. Each hospital recruited all eligible children for a 14-day period commencing on the date chosen by each participating hospital within the study recruitment period from Jan 15 to Dec 23, 2022. Data were collected prospectively for consecutive patients on paper case record forms. The primary outcome was in-hospital postoperative complications within 30 days of surgery and the secondary outcome was in-hospital mortality within 30 days after surgery. We also collected hospital-level data describing equipment, facilities, and protocols available. This study is registered with ClinicalTrials.gov, NCT05061407.

FINDINGS

We recruited 8625 children from 249 hospitals in 31 African countries. The mean age was 6·1 (SD 4·9) years, with 5675 (66·0%) of 8600 children being male. Most children (6110 [71·2%] of 8579 patients) were from category 1 of the American Society of Anesthesiologists Physical Status score undergoing elective surgery (5325 [61·9%] of 8604 patients). Postoperative complications occurred in 1532 (18·0%) of 8515 children, predominated by infections (971 [11·4%] of 8538 children). Deaths occurred in 199 (2·3%) of 8596 patients, 169 (84·9%) of 199 patients following emergency surgeries. Deaths following postoperative complications occurred in 166 (10·8%) of 1530 complications. Operating rooms were reported as safe for anaesthesia and surgery for neonates (121 [54·3%] of 223 hospitals), infants (147 [65·9%] of 223 hospitals), and children younger than 6 years (188 [84·3%] of 223 hospitals).

INTERPRETATION

Outcomes following anaesthesia and surgery for children in Africa are poor, with complication rates up to four-fold higher (18% vs 4·4-14%) and mortality rates 11-fold higher than high-income countries in a crude, unadjusted comparison (23·15 deaths vs 2·18 deaths per 1000 children). To improve surgical outcomes for children in Africa, we need health system strengthening, provision of safe environments for anaesthesia and surgery, and strategies to address the high rate of failure to rescue.

Counseling, informed consent, and debriefing for cesarean section in sub-Saharan Africa: A scoping review

BACKGROUND

Counseling as part of the informed consent process is a prerequisite for cesarean section (CS). Postnatal debriefing allows women to explore their CS with their healthcare providers (HCPs).

OBJECTIVES

To describe the practices and experiences of counseling and debriefing, the barriers and facilitators to informed consent for CS; and to document the effectiveness of the interventions used to improve informed consent found in the peer-reviewed literature.

SEARCH STRATEGY

The databases searched were PubMed, EMBASE, PsycINFO, Africa-wide information, African Index Medicus, IMSEAR and LILACS.

SELECTION CRITERIA

English-language papers focusing on consent for CS, published between 2011 and 2022, and assessed to be of medium to high quality were included.

DATA COLLECTION AND ANALYSIS

A narrative synthesis was conducted using Beauchamp and Childress's elements of informed consent as a framework.

MAIN RESULTS

Among the 21 included studies reporting on consent for CS, 12 papers reported on counseling for CS, while only one reported on debriefing. Barriers were identified at the service, woman, provider, and societal levels. Facilitators all operated at the provider level and interventions operated at the service or provider levels.

CONCLUSIONS

There is a paucity of research on informed consent, counseling, and debriefing for CS in sub-Saharan Africa.

Barriers and Facilitators to Collecting Surgical Outcome Data in Low- and Middle-Income Countries: An International Survey

Background

Perioperative data are essential to improve the safety of surgical care. However, surgical outcome research (SOR) from low- and middle-income countries (LMICs) is disproportionately sparse. We aimed to assess practices, barriers, facilitators, and perceptions influencing the collection and use of surgical outcome data (SOD) in LMICs.

Methods

An internet-based survey was developed and disseminated to stakeholders involved in the care of surgical patients in LMICs. The Performance of Routine Information Systems Management framework was used to explore the frequency and relative importance of organizational, technical, and behavioral barriers. Associations were determined using χ 2 and ANOVA analyses.

Results

Final analysis included 229 surgeons, anesthesia providers, nurses, and administrators from 36 separate LMICs. A total of 58.1% of individuals reported that their institution had experience with collection of SOD and 73% of these reported a positive impact on patient care. Mentorship and research training was available in <50% of respondent's institutions; however, those who had these were more likely to publish SOD (P = 0.02). Sixteen barriers met the threshold for significance of which the top 3 were the burden of clinical responsibility, research costs, and accuracy of medical documentation. The most frequently proposed solutions were the availability of an electronic data collection platform (95.3%), dedicated research personnel (93.2%), and access to research training (93.2%).

Conclusions

There are several barriers and facilitators to collection of SOD that are common across LMICs. Most of these can be addressed through targeted interventions and are highlighted in this study. We provide a path towards advancing SOR in LMICs.

Undergraduate Anesthesia Skills for a Global Surgery Agenda: Students' Self-Reported Competence

BACKGROUND

Safe anesthesia is imperative for the Global Surgery agenda and Sustainable Development Goal 3. Due to a shortage of specialists in South Africa (SA), anesthetic services are often provided by nonspecialist doctors, often newly qualified and frequently without immediate supervision. The burden of disease in the developing world demands fit-for-purpose, day-one medical graduates. Although undergraduate anesthesia training is mandatory for medical students in SA, no outcomes are specified, and these are decided autonomously at each medical school. This study describes the current self-perceived anesthetic competence of medical students in SA as a needs assessment directed at achieving the goals of Global Surgery in SA and other developing countries.

METHODS

In this cross-sectional observational study, 1689 students (89% participation rate), representing all medical schools in SA, rated their self-perceived competence at graduation in 54 anesthetic-related Likert scale items in 5 themes: patient evaluation, patient preparation for anesthesia, practical skills performance, administration of anesthesia, and the management of intraoperative complications. Medical schools were divided into clusters A (≥25 days of anesthetic training) and B (<25 days). Descriptive statistics, Fisher exact test, and a mixed-effects regression model were used in the statistical analysis.

RESULTS

Students felt more prepared for history-taking and patient examination than for managing emergencies and complications. The self-perceived competence of students at cluster A schools was higher across all 54 items and all 5 themes. The same was observed for general medical skills and skills relating to maternal mortality in SA.

CONCLUSIONS

Time-on-task, capacity for repetition, and student maturity might have impacted self-efficacy and should be considered in curriculum development. Students felt less prepared for emergencies. Focused training and assessment aimed at emergency management should be considered. Students did not feel competent in general medical areas, in which anesthetists are experts, including resuscitation, fluid management, and analgesia. Anesthetists should take ownership of this training at the undergraduate level. Cesarean delivery is the most performed surgical procedure in sub-Saharan Africa. The Essential Steps in Managing Obstetric Emergencies (ESMOE) program was designed for internship training but can be introduced at undergraduate level. This study suggests that curriculum reform is required. The achievement of an agreed-upon set of standardized national undergraduate anesthetic competencies may ensure fit-for-purpose practitioners. Undergraduate and internship training should align to form part of a continuum of basic anesthetics training in SA. The findings of this study might benefit curriculum development in other regions with similar contexts.

Gender Disparities in Complications, Costs, and Mortality After Emergency Gastrointestinal Surgery in Kenya

INTRODUCTION

Little is known about the impact of gender on emergency surgery within Kenya. Therefore, we aimed to investigate the association of gender on outcomes of postoperative complications, health care costs, and mortality.

METHODS

We evaluated an established cohort of patients undergoing emergency gastrointestinal surgery in rural Kenya between January 1st, 2016 and June 30th, 2019. Utilizing logistic regression, we examined the association between self-reported patient gender and the outcomes of postoperative complications and mortality. A generalized linear model was created for total hospital costs, inflation-adjusted in international dollars purchasing power parity, to examine the impact of gender. Confounding factors were controlled by Africa Surgical Outcomes Study Surgical Risk Score.

RESULTS

Among 484 patients reviewed, 149 (30.8%) were women. 165 (34.1%) patients developed complications, with women experiencing more than men (40.9% versus 31.0%; P = 0.03) and longer hospital stays (median 6 days (4-9) versus 5 (4-7); P = 0.02). After controlling for Africa Surgical Outcomes Study Surgical Risk Score, odds of developing complications for women were 1.67 (95% confidence interval: 1.09-2.55; P = 0.019) times higher than men, and the odds of death were 2.38 (95% confidence interval: 1.12-5.09; P = 0.025) times greater for women than men, despite similar failure-to-rescue rates and intensive care unit utilization. Total hospital costs were increased for women by 531 international dollars purchasing power parity (117-946; P = 0.012) when compared to men, attributed to longer lengths of stay.

CONCLUSIONS

These findings demonstrate that a discrepancy exists between men and women undergoing emergency gastrointestinal surgery in our setting. Further exploration of the underlying causes of this inequity is necessary for quality improvement for women in rural Kenya.

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.

Prevalence and mortality rate of abdominal surgical emergencies in Sub-Saharan Africa: a systematic review and meta-analysis

INTRODUCTION

Abdominal surgical emergencies remain prevalent in various healthcare settings, particularly in regions with limited access to basic surgical care, such as Africa. The aim of this literature review is to systematically assess publications on abdominal surgical emergencies in adults in sub-Saharan Africa to estimate their prevalence and mortality rate.

METHODOLOGY

A systematic review was conducted. The latest search was performed on October 31, 2022. We estimated the pooled prevalence with a 95% confidence interval (CI) for each abdominal surgical emergency, as well as overall postoperative mortality and morbidity rates.

RESULTS

A total of 78 studies were included, and 55.1% were single-center retrospective and monocentric studies. The mean age of the patients was 32.5 years, with a sex ratio of 1.94. The prevalence of each abdominal surgical emergency among all of them was as follows: appendicitis: 30.0% (95% CI: 26.1-33.9); bowel obstruction: 28.6% (95% CI: 25.3-31.8); peritonitis: 26.6% (95% CI: 22.2-30.9); strangulated hernias: 13,4% (95% CI: 10,3-16,5) and abdominal trauma: 9.4% (95% CI: 7.5-11.3). The prevalence of complications was as follows: mortality rate: 7.4% (95% CI: 6.0-8.8); overall postoperative morbidity: 24.2% (95% CI: 19.4-29.0); and surgical site infection 14.4% (95% CI: 10.86-18.06).

CONCLUSION

Our study revealed a high prevalence of postoperative complications associated with abdominal surgical emergencies in sub-Saharan Africa. More research and efforts should be made to improve access and quality of patient care.

Inequities in global cancer surgery: Challenges and solutions

The disparity in access to and quality of surgical cancer care between high and low resource settings impacts immediate and long-term oncological outcomes. With cancer incidence and mortality set to increase rapidly in the next few decades, we examine the factors leading to inequities in global cancer surgery, and look at potential solutions to overcome these challenges.

Outcomes of Short-Term Surgical Trips in Otolaryngology-Head and Neck Surgery: A Scoping Review

OBJECTIVE

This scoping review aims to explore the current body of literature to characterize how short-term surgical trips (STSTs) in Otolaryngology-Head and Neck Surgery (OtoHNS) contribute to surgical, educational, and sustainability-based outcomes in low- and middle-income countries (LMICs). We aim to use these data to synthesize aspects of STSTs that are successful with the hopes of shaping future global efforts.

DATA SOURCES

Data sources included Ovid MEDLINE, Ovid Embase, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus.

REVIEW METHODS

A comprehensive search was conducted on several databases from inception to October 14, 2021. We included primary studies exploring any surgical or educational outcomes of global short-term surgical endeavors within LMICs. Data were then extracted to evaluate the heterogenous body of literature that exists, characterizing the surgical, educational, and sustainability-based outcomes.

RESULTS

Forty-Seven studies were included in the final analysis. Most publications were focused on surgical interventions (39 of 47; 82.9%); 13 (27.7%) studies included education as the primary aim and 12 (25.5%) considered sustainability a significant aim. Of the 94 first and last authors, there were zero first authors and only one last author with an LMIC affiliation. Twenty-six studies (55%) mentioned that any patients were seen in follow-up, ranging from one day to five years.

CONCLUSION

Our scoping review demonstrates that most STSTs have focused primarily on surgical procedures with a lack of appropriate long-term follow-up. However, the available outcome-based information presented helps identify factors that characterize a strong short-term global surgical program.

Capnography access and use in Kenya and Ethiopia

PURPOSE

Lack of access to safe and affordable anesthesia and monitoring equipment may contribute to higher rates of morbidity and mortality in low- and middle-income countries (LMICs). While capnography is standard in high-income countries, use in LMICs is not well studied. We evaluated the association of capnography use with patient and procedure-related characteristics, as well as the association of capnography use and mortality in a cohort of patients from Kenya and Ethiopia.

METHODS

For this retrospective observational study, we used historical cohort data from Kenya and Ethiopia from 2014 to 2020. Logistic regression was used to study the association of capnography use (primary outcome) with patient/procedure factors, and the adjusted association of intraoperative, 24-hr, and seven-day mortality (secondary outcomes) with capnography use.

RESULTS

A total of 61,792 anesthetic cases were included in this study. Tertiary or secondary hospital type (compared with primary) was strongly associated with use of capnography (odds ratio [OR], 6.27; 95% confidence interval [CI], 5.67 to 6.93 and OR, 6.88; 95% CI, 6.40 to 7.40, respectively), as was general (vs regional) anesthesia (OR, 4.83; 95% CI, 4.41 to 5.28). Capnography use was significantly associated with lower odds of intraoperative mortality in patients who underwent general anesthesia (OR, 0.31; 95% CI, 0.17 to 0.48). Nevertheless, fully-adjusted models for 24-hr and seven-day mortality showed no evidence of association with capnography.

CONCLUSION

Capnography use in LMICs is substantially lower compared with other standard anesthesia monitors. Capnography was used at higher rates in tertiary centres and with patients undergoing general anesthesia. While this study revealed decreased odds of intraoperative mortality with capnography use, further studies need to confirm these findings.

Patient Satisfaction With, and Outcomes of, Ultrasound-Guided Regional Anesthesia at a Referral Hospital in Tanzania: A Cross-Sectional Study

BACKGROUND

Regional anesthesia techniques are increasingly used in high-income countries (HICs) for both surgical anesthesia and postoperative analgesia. However, regional anesthesia has not been utilized to the same degree in low- to middle-income countries (LMICs) due to a lack of resources and trained personnel. This study evaluates patient satisfaction with, and outcomes of, ultrasound-guided regional anesthesia for extremity surgery at Kilimanjaro Christian Medical Center (KCMC) in the Northeastern zone of Tanzania.

METHODS

Study patients were ≥18 years of age; American Society of Anesthesiologists (ASA) physical status I, II, or III; and underwent extremity surgery under peripheral nerve block with ultrasound guidance at KCMC. After placement, blocks were assessed for effectiveness intraoperatively, as demonstrated by the need for supplemental analgesic or sedative medication or conversion to a general anesthetic. Postoperatively, patients were assessed for satisfaction with their nerve block and pain at 12 and 24 hours. Adverse events related to regional anesthesia were assessed immediately, 45 minutes after block placement, and at 12 and 24 hours postoperatively. The primary outcome was patient satisfaction at 12 hours. Secondary outcomes were block success rate and analgesia at 12 and 24 hours postoperatively.

RESULTS

A convenience sample of 170 patients was included in the study, of whom 156 (95% confidence interval [CI], 87-95) were either satisfied or very satisfied with their block. Block placement was highly successful with only 8 of 170 participants (95% CI, 2.4-8.3), requiring conversion to a general anesthetic. Analgesia continued in the postoperative period, with 164 of 170 (95% CI, 93-98) patients and 145 of 170 (95% CI, 80-90) patients reporting acceptable analgesia at 12 and 24 hours, respectively. No major adverse events, such as local anesthetic toxicity, infection, bleeding, nerve injury, or pneumothorax, were observed.

CONCLUSIONS

Our study found that ultrasound-guided regional anesthesia in a resource-constrained setting was effective for extremity surgery and resulted in high patient satisfaction. No complications occurred. The use of ultrasound-guided regional anesthesia shows promise for the safe and effective care of patients undergoing extremity surgery in LMICs.

Perioperative medicine: challenges and solutions for global health

The emerging field of perioperative medicine has the potential to make significant contributions to global health. Perioperative medicine aims to help reduce unmet surgical need, decrease variation in quality and systematically improve patient outcomes. These aims are also applicable to key challenges in global health, such as limited access to surgical care, variable quality and workforce shortages. This article describes the areas in which perioperative medicine can contribute to global health using case studies of successful care pathways, risk prediction tools, strategies for effective grassroots research and novel workforce approaches aimed at effectively using limited resources.

Global Cancer Surgery: pragmatic solutions to improve cancer surgery outcomes worldwide

The first Lancet Oncology Commission on Global Cancer Surgery was published in 2015 and serves as a landmark paper in the field of cancer surgery. The Commission highlighted the burden of cancer and the importance of cancer surgery, while documenting the many inadequacies in the ability to deliver safe, timely, and affordable cancer surgical care. This Commission builds on the first Commission by focusing on solutions and actions to improve access to cancer surgery globally, developed by drawing upon the expertise from cancer surgery leaders across the world. We present solution frameworks in nine domains that can improve access to cancer surgery. These nine domains were refined to identify solutions specific to the six WHO regions. On the basis of these solutions, we developed eight actions to propel essential improvements in the global capacity for cancer surgery. Our initiatives are broad in scope, pragmatic, affordable, and contextually applicable, and aimed at cancer surgeons as well as leaders, administrators, elected officials, and health policy advocates. We envision that the solutions and actions contained within the Commission will address inequities and promote safe, timely, and affordable cancer surgery for every patient, regardless of their socioeconomic status or geographic location.

Outcomes of elective liver surgery worldwide: a global, prospective, multicenter, cross-sectional study

BACKGROUND

The outcomes of liver surgery worldwide remain unknown. The true population-based outcomes are likely different to those vastly reported that reflect the activity of highly specialized academic centers. The aim of this study was to measure the true worldwide practice of liver surgery and associated outcomes by recruiting from centers across the globe. The geographic distribution of liver surgery activity and complexity was also evaluated to further understand variations in outcomes.

METHODS

LiverGroup.org was an international, prospective, multicenter, cross-sectional study following the Global Surgery Collaborative Snapshot Research approach with a 3-month prospective, consecutive patient enrollment within January-December 2019. Each patient was followed up for 90 days postoperatively. All patients undergoing liver surgery at their respective centers were eligible for study inclusion. Basic demographics, patient and operation characteristics were collected. Morbidity was recorded according to the Clavien-Dindo Classification of Surgical Complications. Country-based and hospital-based data were collected, including the Human Development Index (HDI). (NCT03768141).

RESULTS

A total of 2159 patients were included from six continents. Surgery was performed for cancer in 1785 (83%) patients. Of all patients, 912 (42%) experienced a postoperative complication of any severity, while the major complication rate was 16% (341/2159). The overall 90-day mortality rate after liver surgery was 3.8% (82/2,159). The overall failure to rescue rate was 11% (82/ 722) ranging from 5 to 35% among the higher and lower HDI groups, respectively.

CONCLUSIONS

This is the first to our knowledge global surgery study specifically designed and conducted for specialized liver surgery. The authors identified failure to rescue as a significant potentially modifiable factor for mortality after liver surgery, mostly related to lower Human Development Index countries. Members of the LiverGroup.org network could now work together to develop quality improvement collaboratives.

A prediction model for cesarean delivery based on the glycemia in the second trimester: a nested case control study from two centers

OBJECTIVE

Maternal glycemia is associated with the risk of cesarean delivery (CD); therefore, our study aims to developed a prediction model based on glucose indicators in the second trimester to earlier identify the risk of CD.

METHODS

This was a nested case-control study, and data were collected from the 5th Central Hospital of Tianjin (training set) and Changzhou Second People's Hospital (testing set) from 2020 to 2021. Variables with significant difference in training set were incorporated to develop the random forest model. Model performance was assessed by calculating the area under the curve (AUC) and Komogorov-Smirnoff (KS), as well as accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV).

RESULTS

A total of 504 eligible women were enrolled; of these, 169 underwent CD. Pre-pregnancy body mass index (BMI), first pregnancy, history of full-term birth, history of livebirth, 1 h plasma glucose (1hPG), glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), and 2 h plasma glucose (2hPG) were used to develop the model. The model showed a good performance, with an AUC of 0.852 [95% confidence interval (CI): 0.809-0.895]. The pre-pregnancy BMI, 1hPG, 2hPG, HbA1c, and FPG were identifies as the more significant predictors. External validation confirmed the good performance of our model, with an AUC of 0.734 (95%CI: 0.664-0.804).

CONCLUSIONS

Our model based on glucose indicators in the second trimester performed well to predict the risk of CD, which may reach the earlier identification of CD risk and may be beneficial to make interventions in time to decrease the risk of CD.

Delivery of Safe Pediatric Anesthesia Care in the First 8000 days: Realities, Challenges, and Solutions in Low- and Middle-Income Countries

BACKGROUND

Worldwide, perioperative mortality has declined over the past 50 years, but the reduction is skewed toward high-income countries (HICs). Currently, pediatric perioperative mortality is much higher in low- and middle-income countries (LMICs) compared to HICs, despite studied cohorts being predominantly low-risk. These disparities must be studied and addressed.

METHODS

A narrative review of the literature was undertaken to identify contributing factors and potential knowledge gaps. Interventions aimed at alleviating the outcomes disparities are discussed, and recommendations are made for future directions.

RESULTS AND CONCLUSIONS

There is a lack of adequately trained pediatric anesthesia providers in LMICs, and the number must be bolstered by making such training available. Essential anesthesia medications and equipment, in pediatric-appropriate sizes, are often not available; neither are essential infrastructure items. Perioperative staff are underprepared for emergent situations that may arise and simulation training may help to ameliorate this. The global anesthesia community has implemented several solutions to address these issues. The World Federation of Societies of Anaesthesiologists (WFSA) and Global Initiative for Children's Surgery have published standards that outline essential items for the provision of safe perioperative pediatric care. Several short educational courses have been developed and introduced in LMICs that either specifically address pediatric patients, or contain a pediatric component. The WFSA also maintains a collection of discrete tutorials for educational purposes. Finally, in Africa, large-scale, prospective data collection is underway to examine pediatric perioperative outcomes. More work needs to be done, though, to improve perioperative outcomes for pediatric patients in LMICs.

Determinants of Access to Essential Surgery in the Democratic Republic of Congo

INTRODUCTION

In the Democratic Republic of Congo (DRC), the determinants and barriers of essential surgical care are not well described, hindering efforts to improve national surgical programs and access.

METHODS

A cross-sectional study evaluated access to essential surgery in the Butembo and Katwa health zones in the North Kivu province of DRC. A double-clustered random sample of community members was surveyed using questions derived from the Surgeons OverSeas Surgical Needs Assessment Survey, a validated tool to determine the reasons for not seeking, reaching, or receiving a Bellwether surgery (i.e., caesarean delivery, laparotomy, and external fixation of a fracture) when needed.

RESULTS

Overall, 887 households comprising 5944 community members were surveyed from April to August 2022. Six percent (n = 363/5944) of the study population involving 35% (n = 309/887) households needed a Bellwether surgery in the previous year, 30% (n = 108/363) of whom died. Of those who needed surgery, 25% (n = 78) did not go to the hospital to seek care and were more likely to find transportation unaffordable (P = 0.042). The most common reasons for not seeking care were lack of funds for hospitalization, prior poor hospital experience, and fear of hospital care.

CONCLUSIONS

Access and delivery of essential surgery are drastically limited in the North Kivu province of the DRC, such that a quarter of households needing surgery fails to seek surgical care. Poor access was predominantly driven by households' inability to pay for surgery and community distrust of the hospital system.

Capnography-An Essential Monitor, Everywhere: A Narrative Review

Capnography is now recognized as an indispensable patient safety monitor. Evidence suggests that its use improves outcomes in operating rooms, intensive care units, and emergency departments, as well as in sedation suites, in postanesthesia recovery units, and on general postsurgical wards. Capnography can accurately and rapidly detect respiratory, circulatory, and metabolic derangements. In addition to being useful for diagnosing and managing esophageal intubation, capnography provides crucial information when used for monitoring airway patency and hypoventilation in patients without instrumented airways. Despite its ubiquitous use in high-income-country operating rooms, deaths from esophageal intubations continue to occur in these contexts due to incorrect use or interpretation of capnography. National and international society guidelines on airway management mandate capnography's use during intubations across all hospital areas, and recommend it when ventilation may be impaired, such as during procedural sedation. Nevertheless, capnography's use across high-income-country intensive care units, emergency departments, and postanesthesia recovery units remains inconsistent. While capnography is universally used in high-income-country operating rooms, it remains largely unavailable to anesthesia providers in low- and middle-income countries. This lack of access to capnography likely contributes to more frequent and serious airway events and higher rates of perioperative mortality in low- and middle-income countries. New capnography equipment, which overcomes cost and context barriers, has recently been developed. Increasing access to capnography in low- and middle-income countries must occur to improve patient outcomes and expand universal health care. It is time to extend capnography's safety benefits to all patients, everywhere.

Hospital care for critical illness in low-resource settings: lessons learned during the COVID-19 pandemic

Care for the critically ill patients is often considered synonymous with a hospital having an intensive care unit. However, a focus on Essential Emergency and Critical Care (EECC) may obviate the need for much intensive care. Severe COVID-19 presented a specific critical care challenge while also being an exemplar of critical illness in general. Our multidisciplinary team conducted research in Kenya and Tanzania on hospitals' ability to provide EECC as the COVID-19 pandemic unfolded. Important basic inputs were often lacking, especially sufficient numbers of skilled health workers. However, we learnt that higher scores on resource readiness scales were often misleading, as resources were often insufficient or not functional in all the clinical areas they are needed. By following patient journeys, through interviews and group discussions, we revealed gaps in timeliness, continuity and delivery of care. Generic challenges in transitions between departments were identified in the receipt of critically ill patients, the ability to sustain monitoring and treatment and preparation for any subsequent transition. While the global response to COVID-19 focused initially on providing technologies and training, first ventilators and later oxygen, organisational and procedural challenges seemed largely ignored. Yet, they may even be exacerbated by new technologies. Efforts to improve care for the critically ill patients, which is a complex process, must include a whole system and whole facility view spanning all areas of patients' care and their transitions and not be focused on a single location providing 'critical care'. We propose a five-part strategy to support the system changes needed.

Troponin elevation as a marker of short deterioration and one-year death in a high-risk surgical patient cohort in a low and middle income country setting: a postoperative approach to increase surveillance

PURPOSE

Myocardial injury after noncardiac surgery is common and mostly asymptomatic. The ideal target population that will benefit from routine troponin measurements in low and middle income countries (LMICs) is unclear. This study aims to evaluate the clinical outcomes of a cohort of high-risk surgical patients according to high-sensitivity troponin T (hsTnT) in an LMIC setting.

METHODS

We conducted a prospective cohort study of 442 high-risk patients undergoing noncardiac surgery at a Brazilian hospital between February 2019 and March 2020. High-sensitivity troponin T levels were measured preoperatively, 24 hr, and 48 hr after surgery and stratified into three groups: normal (< 20 ng·L-1); minor elevation (20-65 ng·L-1); and major elevation (> 65 ng·L-1). We performed survival analysis to determine the association between myocardial injury and one-year mortality. We described medical interventions and evaluated unplanned intensive care unit (ICU) admission and complications using multivariable models.

RESULTS

Postoperative myocardial injury occurred in 45% of patients. Overall, 30-day mortality was 8%. Thirty-day and one-year mortality were higher in patients with hsTnT ≥ 20 ng·L-1. One-year mortality was 18% in the unaltered troponin group vs 31% and 41% for minor and major elevation groups, respectively. Multivariable analysis of one-year survival showed a hazard ratio (HR) of 1.94 (95% confidence interval [CI], 1.22 to 3.09) for the minor elevation group and a HR of 2.73 (95% CI, 1.67 to 4.45) for the troponin > 65 ng·L-1 group. Patients with altered troponin had more unplanned ICU admissions (13% vs 5%) and more complications (78% vs 48%).

CONCLUSION

This study supports evidence that hsTnT is an important prognostic marker and a strong predictor of all-cause mortality after surgery. Troponin measurement in high-risk surgical patients could potentially be used as tool to scale-up care in LMIC settings.

Barriers to Surgical Outcomes Research in Low- and Middle-Income Countries: A Scoping Review

INTRODUCTION

Systematic collection and analysis of surgical outcomes data is a cornerstone of surgical quality improvement. Unfortunately, there remains a dearth of surgical outcomes data from low- and middle-income countries (LMICs). To improve surgical outcomes in LMICs, it is essential to have the ability to collect, analyze, and report risk-adjusted postoperative morbidity and mortality data. This study aimed to review the barriers and challenges to developing perioperative registries in LMIC settings.

METHODS

We conducted a scoping review of all published literature on barriers to conducting surgical outcomes research in LMICs using PubMed, Embase, Scopus, and GoogleScholar. Keywords included 'surgery', 'outcomes research', 'registries', 'barriers', and synonymous Medical Subject Headings derivatives. Articles found were subsequently reference-mined. All relevant original research and reviews published between 2000 and 2021 were included. The performance of routine information system management framework was used to organize identified barriers into technical, organizational, or behavioral factors.

RESULTS

Twelve articles were identified in our search. Ten articles focused specifically on the creation, success, and obstacles faced during the implementation of trauma registries. Technical factors reported by 50% of the articles included limited access to a digital platform for data entry, lack of standardization of forms, and complexity of said forms. 91.7% articles mentioned organizational factors, including the availability of resources, financial constraints, human resources, and lack of consistent electricity. Behavioral factors highlighted by 66.6% of the studies included lack of team commitment, job constraints, and clinical burden, which contributed to poor compliance and dwindling data collection over time.

CONCLUSIONS

There is a paucity of published literature on barriers to developing and maintaining perioperative registries in LMICs. There is an immediate need to study and understand barriers and facilitators to the continuous collection of surgical outcomes in LMICs.

Perioperative mortality of emergency and elective surgical patients in a low-income country: a single institution experience

BACKGROUND

The perioperative mortality rate is an indicator of access to safe anesthesia and surgery. Studies showed higher perioperative mortality rates among low- and middle-income countries. But the specific causes and factors contributing to perioperative death have not been adequately studied in the Ethiopian context.

METHODS

This is a retrospective institutional study of the largest academic medical center in Ethiopia. Data of all patients who were admitted to surgical wards or intensive care and underwent surgical interventions were evaluated for perioperative mortality rate determination. All mortality cases were then evaluated in depth.

RESULTS

Of the 3295 patients evaluated, a total of 148 patients (4.5%) died within 30 days of surgery. By the 7th postoperative day, 69.5% of the perioperative mortality had already occurred. Septic shock contributed to 54.2% of deaths. Emergency surgery patients had more than a twofold higher mortality rate than elective surgery patients (p value < 0.001) and had a 2.6-fold higher rate of dying within 7 days of surgery (p value of 0.02). Patients with ASA performance status of 3 or more had a 1.7-fold higher rate of death within 72 h of surgery (p value of 0.015).

CONCLUSION

More than two thirds of patients died within 7 postoperative days. More emergency patients died than elective counterparts, and emergency cases had a higher rate of dying within 7 days of surgery. Poor ASA performance score was associated with earlier postoperative death. Further prospective multi-institutional studies are warranted to elucidate the factors that contribute to higher postoperative mortality in low-income country patients.

Exploring the cost-effectiveness of high versus low perioperative fraction of inspired oxygen in the prevention of surgical site infections among abdominal surgery patients in three low- and middle-income countries

Background

This study assessed the potential cost-effectiveness of high (80-100%) vs low (21-35%) fraction of inspired oxygen (FiO2) at preventing surgical site infections (SSIs) after abdominal surgery in Nigeria, India, and South Africa.

Methods

Decision-analytic models were constructed using best available evidence sourced from unbundled data of an ongoing pilot trial assessing the effectiveness of high FiO2, published literature, and a cost survey in Nigeria, India, and South Africa. Effectiveness was measured as percentage of SSIs at 30 days after surgery, a healthcare perspective was adopted, and costs were reported in US dollars ($).

Results

High FiO2 may be cost-effective (cheaper and effective). In Nigeria, the average cost for high FiO2 was $216 compared with $222 for low FiO2 leading to a -$6 (95% confidence interval [CI]: -$13 to -$1) difference in costs. In India, the average cost for high FiO2 was $184 compared with $195 for low FiO2 leading to a -$11 (95% CI: -$15 to -$6) difference in costs. In South Africa, the average cost for high FiO2 was $1164 compared with $1257 for low FiO2 leading to a -$93 (95% CI: -$132 to -$65) difference in costs. The high FiO2 arm had few SSIs, 7.33% compared with 8.38% for low FiO2, leading to a -1.05 (95% CI: -1.14 to -0.90) percentage point reduction in SSIs.

Conclusion

High FiO2 could be cost-effective at preventing SSIs in the three countries but further data from large clinical trials are required to confirm this.

Trainee autonomy and surgical outcomes after emergency gastrointestinal surgery

BACKGROUND

Operative meaningful trainee autonomy is an essential component of surgical training. Reduced trainee autonomy is frequently attributed to patient safety concerns, but this has not been examined within Kenya. We aimed to assess whether meaningful trainee autonomy was associated with a change in patient outcomes.

METHODS

We investigated whether meaningful trainee autonomy was associated with a change in severe postoperative complications and all-cause in-hospital mortality in a previously described cohort undergoing emergency gastrointestinal operations. Each operation was reviewed to determine the presence of meaningful autonomy, defined as "supervision only" from faculty. Comparisons were made between faculty-led cases and cases with meaningful trainee autonomy. Multilevel logistic regression models were created for the outcomes of mortality and complications with the exposure of meaningful trainee autonomy, accounting for fixed effects of the Africa Surgical Outcomes Study Risk Score and random effects of discharge diagnoses.

RESULTS

After excluding laparoscopy (N = 28) and missing data (N = 3), 451 operations were studied, and 343 (76.1%) had meaningful trainee autonomy. Faculty were more involved in operations with older age, cancer, prior complications, and higher risk scores. On unadjusted analysis, meaningful trainee autonomy was associated with mortality odds of 0.32 (95% confidence interval: 0.17-0.58) compared with faculty-led operations. Similarly, the odds of developing complications were 0.52 (95% confidence interval: 0.32-0.84) with meaningful trainee autonomy compared with faculty-led operations. When adjusting for Africa Surgical Outcomes Study Score and clustering discharge diagnoses, the odds of mortality (odds ratio 0.58; 95% confidence interval: 0.27-1.2) and complication (odds ratio 0.83; 95% confidence interval: 0.47-1.5) were not significant.

CONCLUSION

Our findings support that increasing trainee autonomy does not change patient outcomes in selected emergency gastrointestinal operations. Further, trainees and faculty appropriately discern patients at higher risk of complications and mortality, and the selective granting of trainee autonomy does not affect patient safety.

Mentoring approaches in a safe surgery program in Tanzania: Lessons learned during COVID-19 and recommendations for the future

Background

COVID-19 has dramatically affected the delivery of health care and technical assistance. This is true in Tanzania, where maternal mortality and surgical infection rates are significantly higher than in high-income countries. This paper describes lessons learned about the optimal application of in-person and virtual mentorship in the Safe Surgery 2020 program to improve the quality of surgical services in Tanzania before and after the COVID-19 pandemic.

Methods

From January 2018 through December 2020, Safe Surgery 2020 supported 40 health facilities in Tanzania's Lake Zone to improve the quality of surgical care. A blended surgical mentorship model, employing both onsite and virtual mentorship, was central to the program's capacity development approach. With COVID-19, the program pivoted to full virtual mentorship. Through continuous learning and adaptation processes, including a human-centered design workshop, surveys assessing mentors' confidence with different competencies, and focus group discussions with mentors, mentees and safe surgery program staff, the program distilled the optimal use of mentorship models.

Results

Developing complex surgical skills, addressing contextual considerations, problem-solving, and building trusting relationships were best suited to in-person mentorship, whereas virtual mentorship was most effective in supporting mentees' quality improvement projects, data use, case discussions, and reinforcing clinical practices. Leading successful virtual learning required enhanced facilitation skills and active engagement of health facility leadership.

Conclusions

In-person and virtual mentorship offer distinct benefits and complement each other when combined. Investing more in-person mentorship at the beginning of programs allows for the establishment of trust that is foundational to effective mentorship.
