Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10&nbsp;years; 78.2% included were male with a median age of 37&nbsp;years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Music therapy for postoperative pain management after mastectomy in Nigeria: An exploratory qualitative study

Abstract Purpose This study aimed to explore the cultural elements of music in relation to pain management among women who have undergone mastectomy. Method: An exploratory qualitative study with in-depth interviews. Using the purposive sampling technique, 20 participants were recruited for the study. The interviews were conducted face to face at the surgical out-patient clinic and female surgical ward. Data collection continued until data saturation was reached. The inductive approach was used to analyse the data, and the concepts were organized into themes. The consolidated criteria for reporting qualitative research guidelines (COREQ) were used to report this study. Results The participants were between 28 and 83 years old and mostly diagnosed with Stage III breast cancer. Three main themes emerged from the data analysis, including pain experienced after mastectomy, culture and music, and the perception of music for postoperative pain management after mastectomy. Conclusion Knowledge and the utilisation of music as a therapy for pain management remains inadequate, but the participants perceived that music could be useful for pain control after mastectomy when the language and religion of the patient and the meaningfulness of the music were considered when introducing and selecting the music. This study will help open and extend the conversation about the utilisation and cultural elements of music that can be used clinically for pain management after mastectomy.</jats:p

Chronic neck sinus secondary to retained polyglactin 910 suture following sub-total thyroidectomy: a case study

Objective: Reaction to sutures is a rare cause of non-healing in clean wounds. Cases of severe reaction to silk sutures have been reported, causing chronic infection and failure of thyroidectomy wound healing. We report a case of retained polyglactin 910 suture presenting with a chronically discharging sinus of the neck after sub-total thyroidectomy. Case: The patient, a 37-year old female, presented with a simple benign multinodular goitre. She had subtotal thyroidectomy and was discharged on day six postoperatively, after satisfactory primary wound healing. The patient observed swelling, pus/discharge and extrusion of the suture in the neck three weeks after surgery. Discharge did not stop after initial wound debridement under local anaesthesia. Computed tomography (CT) scan showed a small area of ring-enhancement soft tissue density, anterior to the right thyroid remnant. Subsequent wound exploration under general anaesthesia revealed a sinus tract extending to the thyroid bed with undegraded strands of thickened polyglactin 910 suture. Suture remnants were removed and the wound healed satisfactorily a week later. Conclusion: Non-healing post thyroidectomy wounds should raise suspicion of a retained suture. Early recognition and surgical intervention will shorten the period of morbidity. </jats:sec

Association of Chronic Pain with Motor Symptom Severity in Parkinson&rsquo;s Disease: An Exploratory Cross-Sectional Analysis

Background: Parkinson&rsquo;s disease (PD) is a neurodegenerative disorder characterized by motor symptoms like bradykinesia, tremor, rigidity, and postural instability. Additionally, PD severely impacts physical abilities and independence. Chronic pain, affecting 67.6% of PD patients, varies in form and presentation, and it is often underdiagnosed. Objectives: This study investigated the association between chronic pain and motor symptom severity in PD patients. Methods: This analysis used data from a cross-sectional study on 52 Parkinson&rsquo;s disease (PD) patients conducted at Jena University Hospital, Germany. The dataset, available on Dryad, included demographics; clinical reports; and assessments of coping strategies, quality of life, and pain. Descriptive statistics, a bivariate analysis, and an ordinal logistic regression model were executed to explore the association between pain and motor symptom severity (MSS). A direct acyclic graph was used to represent the relationship between variables and identify potential confounders, and an outcomes definition sensitivity analysis was used to assess the impact of using pain intensity as an outcome. The E-value was calculated to evaluate the strength of association needed by an unmeasured confounder to nullify the observed association. Results: A total of 50 Parkinson&rsquo;s disease (PD) patients were included, with 64% being male, with an average age of 76.1 years. The sample included 20 patients without pain and 30 with chronic pain. The bivariate analysis did not identify significant differences in disease duration, cognitive function, and non-motor symptoms between pain and no-pain groups. However, significant differences (p-value &lt; 0.05) emerged in motor symptom severity, coping strategies, and several SF-36 domains (Physical and Social Functioning, Role Functioning, Energy/Fatigue, Pain, General Health, and Health Change). The ordinal logistic regression showed a substantial association between chronic pain and MSS: patients with chronic pain had 3.52 times higher odds (95% CI: 1.40&ndash;8.84, effect size d &asymp; 0.70, p = 0.02) of low to medium MSS and 5.44 times higher odds (95% CI: 2.03&ndash;14.60, effect size d &asymp; 0.94, p = 0.01) of medium to severe MSS, indicating a dose&ndash;response relationship. Additionally, male patients had increased odds of higher MSS (OR 4.63, 95% CI: 1.15&ndash;18.58, effect size d &asymp; 0.85, p = 0.03). Conclusions: Chronic pain is strongly associated with MSS in PD patients, with a more pronounced effect as MSS progresses from medium to severe, supporting a dose&ndash;response relationship. Effect sizes suggest a robust association, emphasizing the need for pain assessment in managing motor symptoms in PD

Unique microbial biomarkers identified in Nigerian patients with colorectal cancer.

222 Background: The microbiome is an important biomarker associated with the pathogenesis and progression of disease in colorectal cancer (CRC). Genetic, dietary and environmental factors have been implicated in CRC microbial dysbiosis, however geographical distinctions in the microbiome of CRC are largely unknown. In this study, we characterize distinctions in the microbial diversity and microbial enrichment of CRC specimen obtained from a Nigerian and U.S. population. Methods: A validated microbiome bioinformatics pipeline that is generalizable across multiple next generation sequencing platforms was utilized. Microbial profiles for alpha diversity and enrichment were generated for two large, geographically distinct cohorts: (1) U.S. (n=498) and (2) Nigerian (n=65) cohorts. CRC specimen from Nigeria were compared to CRC specimen from the U.S. using the same microbial bioinformatics pipeline and methodology for analysis. Microbial differences stratified based on CRC microsatellite-instability (MSI) status were identified. Results: 9 unique microbial species were significantly enriched in the CRC specimen from the Nigerian cohort when compared to the US cohort. Subset analysis based on MSI status revealed enrichment of Faecalibacterium and Veillonella in the Nigerian cohort for both MSI and microsatellite stable (MSS) CRC (Table). Prevotella was significantly enriched in MSS CRC in the Nigerian cohort (OR=53.35, CI=10.34,275.37, p&lt;0.001). There were no significant differences in alpha diversity between the Nigerian and U.S. cohorts (p&gt;0.05). Conclusions: Several unique species with taxonomic diversity are enriched in Nigerian CRC and can be independently validated based on stratification by MSI status. Given the varied accessibility of diagnostic and therapeutic tools for CRC in these distinct geographical settings, understanding unique microbial biomarkers will provide the landscape to explore key microbial targets for therapy specific to this population.[Table: see text] </jats:p

Surgical site infection after gastrointestinal surgery in children : an international, multicentre, prospective cohort study

Introduction Surgical site infection (SSI) is one of the most common healthcare-associated infections (HAIs). However, there is a lack of data available about SSI in children worldwide, especially from low-income and middle-income countries. This study aimed to estimate the incidence of SSI in children and associations between SSI and morbidity across human development settings. Methods A multicentre, international, prospective, validated cohort study of children aged under 16 years undergoing clean-contaminated, contaminated or dirty gastrointestinal surgery. Any hospital in the world providing paediatric surgery was eligible to contribute data between January and July 2016. The primary outcome was the incidence of SSI by 30 days. Relationships between explanatory variables and SSI were examined using multilevel logistic regression. Countries were stratified into high development, middle development and low development groups using the United Nations Human Development Index (HDI). Results Of 1159 children across 181 hospitals in 51 countries, 523 (45 center dot 1%) children were from high HDI, 397 (34 center dot 2%) from middle HDI and 239 (20 center dot 6%) from low HDI countries. The 30-day SSI rate was 6.3% (33/523) in high HDI, 12 center dot 8% (51/397) in middle HDI and 24 center dot 7% (59/239) in low HDI countries. SSI was associated with higher incidence of 30-day mortality, intervention, organ-space infection and other HAIs, with the highest rates seen in low HDI countries. Median length of stay in patients who had an SSI was longer (7.0 days), compared with 3.0 days in patients who did not have an SSI. Use of laparoscopy was associated with significantly lower SSI rates, even after accounting for HDI. Conclusion The odds of SSI in children is nearly four times greater in low HDI compared with high HDI countries. Policies to reduce SSI should be prioritised as part of the wider global agenda.Peer reviewe

Management and Outcomes Following Surgery for Gastrointestinal Typhoid: An International, Prospective, Multicentre Cohort Study

Background: Gastrointestinal perforation is the most serious complication of typhoid fever, with a high disease burden in low-income countries. Reliable, prospective, contemporary surgical outcome data are scarce in these settings. This study aimed to investigate surgical outcomes following surgery for intestinal typhoid. Methods: Two multicentre, international prospective cohort studies of consecutive patients undergoing surgery for gastrointestinal typhoid perforation were conducted. Outcomes were measured at 30 days and included mortality, surgical site infection, organ space infection and reintervention rate. Multilevel logistic regression models were used to adjust for clinically plausible explanatory variables. Effect estimates are expressed as odds ratios (ORs) alongside their corresponding 95% confidence intervals. Results: A total of 88 patients across the GlobalSurg 1 and GlobalSurg 2 studies were included, from 11 countries. Children comprised 38.6% (34/88) of included patients. Most patients (87/88) had intestinal perforation. The 30-day mortality rate was 9.1% (8/88), which was higher in children (14.7 vs. 5.6%). Surgical site infection was common, at 67.0% (59/88). Organ site infection was common, with 10.2% of patients affected. An ASA grade of III and above was a strong predictor of 30-day post-operative mortality, at the univariable level and following adjustment for explanatory variables (OR 15.82, 95% CI 1.53–163.57, p = 0.021). Conclusions: With high mortality and complication rates, outcomes from surgery for intestinal typhoid remain poor. Future studies in this area should focus on sustainable interventions which can reduce perioperative morbidity. At a policy level, improving these outcomes will require both surgical and public health system advances
