Challenges and opportunities in providing high-quality surgical care in Canada.

SummaryThe provision of surgical care in Canada requires substantial improvement. In this commentary, we use the US Institute of Medicine's framework for assessing the quality of health care to explore system-wide challenges that affect surgical outcomes in Canada. Challenges include surgical wait times, long travel times for surgery, human resource constraints, equitable access to surgery, limited collection of data about the surgical pathway, a lack of transparency in the reporting of surgical outcomes and a lack of incentives for hospital systems to achieve high-quality outcomes. We propose solutions supported by available literature to help overcome some of these challenges.

Transient neonatal pustular melanosis: An unusual and challenging eruption.

TNPM is a benign, transient, neonatal pustulosis requiring no active treatment. Diagnosis is clinical, characterized by a vesiculopustular eruption, healing with residual hyperpigmented macules. Before diagnosing TNPM, serious conditions including skin infections should be excluded. This case was unusual in that vesiculobullae predominated, with a notable absence of simple pustules.

Imported Malaria in Children: A Study Over an 11-Year Period in Brussels.

BACKGROUND: Malaria is a major global public health concern in endemic countries and imported childhood malaria is increasing in malaria non-endemic countries. METHODS: This was a retrospective case review of all laboratory-confirmed malaria cases in children 0-16 years admitted between 2009 and 2019 in 2 large university teaching Hospitals in Brussels. RESULTS: A total of 160 children with a median age of 6.8 years (range 5-191 months) were included. We identified 109 (68%) children living in Belgium who had acquired malaria during their visit to malaria-endemic countries to visiting friends and relatives (VFRs), 49 children (31%) visitors or newly installed migrants, and 2 Belgian tourists. Peak seasonal incidence occurred between August and September. Plasmodium falciparum was responsible for 89% of all malaria cases. Almost 80% of children living in Belgium visited a travel clinic for advice, but only one-third reported having taken the prophylaxis schedule according to the recommendations. Based on WHO criteria, 31 children (19.3%) developed severe malaria; most of the patients with severe malaria were VFR travelers and were significantly younger, had higher leukocytosis, had more thrombocytopenia, higher CRP, and lower natremia compared with patients with an uncomplicated course. All children recovered fully. CONCLUSIONS: Malaria is a significant cause of morbidity among returning travelers and newly arrived immigrants to Belgium. Most of the children had an uncomplicated disease course. Physicians should educate families about traveling to malaria-endemic areas to correct malaria preventive measures and prophylaxis.

An estimation of the endoscopist's musculoskeletal injury risk for right and left lateral decubitus positions during colonoscopy: a field-based ergonomic study.

BACKGROUND: Colonoscopy exposes endoscopists to awkward postures and prolonged forces, which increases their risk of musculoskeletal injury. Patient positioning has a significant impact on the ergonomics of colonoscopy. Recent trials have found the right lateral decubitus position is associated with quicker insertion, higher adenoma detection rates, and greater patient comfort compared to the left lateral decubitus position. However, this patient position is perceived as more strenuous by endoscopists. METHODS: Nineteen endoscopists were observed performing colonoscopies during a series of four-hour endoscopy clinics. Durations of each patient position (right lateral decubitus, left lateral decubitus, prone, and supine) were recorded for all observed procedures (n = 64). Endoscopist injury risk was estimated by a trained researcher for the first and last colonoscopies of the shifts (n = 34) using Rapid Upper Limb Assessment (RULA), an observational ergonomic tool that estimates risk of musculoskeletal injury by scoring postures of the upper body and factors such as muscle use, force, and load. The total RULA scores were compared with a Wilcoxon Signed-Rank test for patient position (right and left lateral decubitus) and time (first and last procedures) with significance taken at p < 0.05. Endoscopist preferences were also surveyed. RESULTS: The right lateral decubitus position was associated with significantly higher RULA scores than the left lateral decubitus position (median 5 vs. 3, p < 0.001). RULA scores were not significantly different between the first and last procedures of the shifts (median 5 vs. 5, p = 0.816). 89% of endoscopists preferred the left lateral decubitus position, primarily due to superior ergonomics and comfort. CONCLUSION: RULA scores indicate an increased risk of musculoskeletal injury in both patient positions, with greater risk in the right lateral decubitus position.

Ambulatory surgery centres: a potential solution to a chronic problem.

SummaryLong wait times for elective surgery in Canada have been a persistent problem for many years and the recent pandemic has made the situation substantially worse. Current evidence suggests that ambulatory surgery centres are more cost-effective and efficient in the delivery of ambulatory surgical services than larger institutions. We explore the merits of a network of publicly funded ambulatory surgery centres.

Ursodeoxycholic acid for prevention of gallstone disease after laparoscopic sleeve gastrectomy: an Atlantic Canada perspective.

BACKGROUND: Prophylactic ursodeoxycholic acid (UDCA) may be beneficial in reducing gallstone disease after bariatric surgery. The American Society for Metabolic and Bariatric Surgery (ASMBS) 2019 guidelines recommend a 6-month course of UDCA for patients undergoing laparoscopic sleeve gastrectomy (LSG). This has not been adopted broadly. This study intends to assess the effect of routine UDCA administration following LSG on symptomatic gallstone disease. METHODS: We performed a retrospective chart review of patients who underwent LSG, between 2009 and 2019, at two tertiary care centers in Atlantic Canada. At one center, UDCA 250 mg oral twice daily was routinely prescribed following LSG for 6 months to patients with an intact gallbladder. At the other center, UDCA was not prescribed. Primary and secondary outcomes were cholecystectomy and endoscopic retrograde cholangiopancreatography (ERCP) rates. Compliance with and side effects of UDCA therapy were analyzed. RESULTS: A total of 751 patients were included in the study. Patients who had prior cholecystectomy or were lost to follow up were excluded. After exclusion criteria were applied, 461 patients were included for analysis: 303 in the UDCA group and 158 in the group who did not receive UDCA. Cholecystectomy rate was not significantly associated with UDCA administration, however there was a trend towards less cholecystectomy in patients who received UDCA (8.3% vs. 13.9%, p = 0.056). ERCP rate was significantly lower in patients who received UDCA (0.3% vs 2.5%, p = 0.031). Rate of gallstone disease requiring intervention, either cholecystectomy or ERCP, was significantly decreased in patients who received UDCA (8.9% vs 15.8%, p = 0.022). The most common barriers to compliance with UDCA were cost (45.4%) and nausea (18.1%). CONCLUSION: This is the first study to demonstrate lower rates of ERCP in patients receiving routine UDCA following LSG. Our findings support the ASMBS 2019 guidelines for administering UDCA after LSG for preventing gallstone disease.

Characteristics of Interval Colorectal Cancer: A Canadian Retrospective Population-Level Analysis from Newfoundland and Labrador.

Interval colorectal cancers (I-CRCs) arise during the interval time period between scheduled colonoscopies. Predicting which patients are at risk of I-CRCs remains an elusive undertaking, but evidence would suggest that most I-CRCs arise from lesions missed on index endoscopy. The procedural factors that lead to missed lesions are numerous and lack consensus in the literature. In Canada, the province of Newfoundland and Labrador has the highest incidence of CRCs. In this study our aim was to examine I-CRCs (3-60 months after last colonoscopy) in NL through a population-level analysis covering 67% of the province from 2001-2018. We estimated the I-CRC rate to be up to 9.3%. Median age of I-CRC diagnosis was 67.1 years with an interval time of 2.9 years. About 57% of these tumors occurred proximal to the splenic flexure, with 53% presenting as local disease. No temporal differences were observed in interval time or tumor distribution. On univariate and multivariable logistical regression, risk of right-sided I-CRC did not correlate to the index colonoscopy indication, bowel preparation quality, size of largest polyp removed, colonoscopy completion rate, or stage at presentation. Improvements in synoptic reporting utilization and national registries are needed to identity risk factors and reduce I-CRC frequency.

Research and surgical residency: moving beyond one-and-done projects and motivating for scholarly excellence.

Among surgical residents, research is often perceived as a check-mark exercise. Focus then turns to studying for exams and honing skills for independent practice. While some residents are passionate about research and enroll in other formalized training, pragmatists argue that not every surgeon should engage in research at this level. However, no resident should view research as a one-and-done activity. Rather, research should be viewed as an exercise to improve practice, share gaps in knowledge, collaborate, and empower others to formally study and implement change. The skills acquired during research experiences, at minimum, have value in improving the trainee's literature literacy, which in turn serves as a foundational element of continuing medical education. A culture supportive of scientific discovery, facilitated by both faculty and peer-to-peer mentorship, will result in better collaborative efforts and lead to improved knowledge generation and resident research satisfaction.

A framework for role allocation in education, research and leadership services in Canadian academic divisions of general surgery: a modified Delphi consensus.

BACKGROUND: Moving toward a funding standard similar to that for clinical services for roles essential to the functioning of education, research and leadership services within divisions of general surgery is necessary to strengthen divisional resilience. We aimed to identify roles and underlying tasks in these services central to sustainable functioning of Canadian academic divisions of general surgery. METHODS: Between June 2018 and October 2020, we used a 4-step modified Delphi method (online survey, face-to-face nominal group technique [n = 12], semistructured telephone interview [n = 8] and nominal group technique [n = 12]) to achieve national consensus from an expert panel of all 17 heads of academic divisions of general surgery in Canada on the roles and accompanying tasks essential to education, research and leadership services within an academic division of general surgery. We used 70% agreement to determine consensus. RESULTS: The expert panel agreed that a framework for role allocation in education, research and leadership services was relevant and necessary. Consensus was reached for 7 roles within the educational service, 3 roles within the research service and 5 roles within the leadership service. CONCLUSION: Our framework represents a national consensus that defines role standards for education, research and leadership services in Canadian academic divisions of general surgery. The framework can help divisions build resiliency, and enable sustained and deliberate advances in these services.

Optimizing cecal views during colonoscopy using patient position change.

BACKGROUND: Patient positioning has been found to be a simple technique to improve luminal distention and visualization during colonoscopy. This study examined which position provided the cleanest image of the cecum using the Boston Bowel Prep Scale (BBPS) and the best view of the cecum overall as ranked by blinded assessors. METHODS: A sample of 90 sets of cecal images were obtained from patients undergoing a non-urgent colonoscopy. Each set included cecal images of patients while lying in three positions-right lateral decubitus, left lateral decubitus, and supine. Two authors reviewed these sets of images and excluded those that were unclear. A third author, blinded to the position, selected the final 33 sets of images. Two experienced endoscopists completed a blinded survey of each image set. They used the BBPS to assess and score each image as the primary outcome measure. The endoscopists also ranked each image set in terms of the best overall view of the cecum. Data were collected using Qualtrics software. Nonparametric tests were used to analyze the data using SPSS software (v.25). A p-value of ≤ 0.05 was considered significant. RESULTS: The BBPS showed a significant difference between patient positions when tested by Kruskal-Wallis. Subsequent Mann Whitney U tests indicated that the right lateral decubitus position was ranked higher than left lateral decubitus or supine positions. There was no significant difference in the left and supine positions. Cohen's Kappa suggested moderate agreement between raters. The raters also favored the right lateral position over the other positions when assessing overall image preference displaying the cecum. CONCLUSION: These results indicate that positioning patients in the right lateral decubitus position provides the best view of the cecum during colonoscopy.

Management of the colonic polyps referred for surgery: an opportunity for improvement.

PURPOSE: To examine local practice for non-malignant polyps and to calculate morbidity and mortality associated with bowel resection for this indication. METHODS: This retrospective cohort study was conducted by reviewing our local gastrointestinal pathology database over a five-year period to identify colonic resections performed for benign polyps. Using search terms "polyp" and "adenoma," 272 cases were identified. Exclusion criteria included: cancer diagnosis, emergency surgeries, multiple resections, and subtotal colectomies for polyposis. 106 patients were included in the study. Primary outcome was perioperative mortality. Secondary outcomes included patient morbidity, characteristics of polyps requiring surgery, and the number of patients referred for a second endoscopic opinion prior to proceeding with surgery. RESULTS: 64 male and 42 female patients with a mean age of 65.3 years (± 8.6 years) underwent colon resection for benign polyps. The mean polyp size was 32.7 mm (± 19.5 mm). 30 patients (28.6%) had polyps equal to or less than 2 cm. Most of the polyps described were sessile (n = 55, 51.9%) and located in the right colon (n = 84, 79.3%). Endoscopic resection was attempted in 31 patients (29.2%), and five cases (4.7%) were referred for a second endoscopic opinion prior to proceeding with surgery. Endoscopists incorrectly felt that polyps were malignant in 62 cases (58.5%). Using Clavien-Dindo classification, most patients had no complications n = 36 (34.0%) or minor complications n = 41 (38.7%). Twelve patients (11.3%) had complications that required antibiotics, blood transfusions, or total parental nutrition. Nine patients (8.5%) required surgical or endoscopic management. Six patients (5.7%) required ICU admission. Mortality rate was 1.9% (n = 2). CONCLUSION: Surgery for benign colonic polyps is associated with significant morbidity and mortality. These findings reveal a gap in endoscopic management of benign colonic polyps.

Paediatric enteric fever in Brussels: a case series over 16 years.

Enteric fever (EF) is a major public health problem and a witness of the global health disparities. It is caused by Salmonella enterica serovar Typhi (Salmonella ser. Typhi) and Salmonella enterica serovar Paratyphi A, B, C (Salmonella ser. Paratyphi) and is estimated to infect 12-26 million persons yearly. Paediatric data on enteric fever in Europe are scarce. A case series of EF was analysed to describe the clinical presentation, laboratory characteristics and diagnostic challenges identified in a paediatric population in Brussels. We performed a retrospective study of all lab-confirmed cases of enteric fever in children aged 0-15 years at two Brussels teaching hospitals, between January 2005 and December 2020. We reviewed age, gender, travel history, consultations before diagnosis, hospitalisation duration, clinical symptoms and laboratory findings. There were 34 positive isolates of S. typhi and S. paratyphi: 31 patients had positive blood culture, 1 patient had positive bone aspirate and 2 patients had positive stool culture (one was excluded for missing data). There were 20 girls (60%). Median age was 3.5 years (range 5 months to 14 years). Travel to EF endemic areas was present in 55% of patients. Diagnosis was delayed in 80% of children. Eosinopenia was present in 93% of the cohort. The patients had not received any preventive travel education or vaccination.  Conlusion: Enteric fever poses diagnostic challenges to clinicians. Eosinopenia in a febrile patient coming from the tropics should raise suspicion of EF. Travellers to endemic areas should be better educated about EF risks, and typhoid fever vaccination must be promoted. What is Known: • Enteric fever is a global public health problem and includes typhoid and paratyphoid fever. • Typhoid fever is vaccine preventable disease. Paratyphoid fever is not vaccine preventable. What is New: • Enteric fever diagnosis is very challenging in non-endemic settings, and a large proportion of patients may develop serious complications if they receive delayed management. Occurrence of small family clusters is possible and mandates education and monitoring of the families of enteric fever affected children. • We report that the widest majority of our enteric fever affected patients (69%) had aneosinophilia (zero eosinophil count), and almost all patients (93%) had eosinopaenia (less than 50 eosinophil count) during their bacteriaemic phase.

Mesangiocapillary glomerulonephritis complicating pulmonary tuberculosis.

Glomerulonephritis in tuberculosis may be a direct manifestation of renal infection or a result of immune-complex deposition complicating extra-renal infection, such as in pulmonary tuberculosis. A 17-year-old adolescent boy from Somalia was found to have pulmonary tuberculosis during routine health screening performed on entering Malta, with computed tomography of the chest showing scarring and calcification of the left upper lobe, left lower lobe consolidation, and a small left-sided pleural effusion. Five days after starting anti-tuberculous therapy, he developed lower limb and sacral oedema: urinary albumin: creatinine ratio was > 400 µg albumin/mg creatinine, and 24-h urinary protein showed nephrotic-range proteinuria of 4.963 g/day. In view of worsening lower limb, sacral and periorbital oedema and ascites, he was started on oral prednisolone, omeprazole and penicillin V prophylaxis. As heavy proteinuria persisted, a renal biopsy was performed after 8 days of prednisolone treatment, which confirmed the presence of mesangiocapillary glomerulonephritis (MCGN), with electron microscopy showing effacement of the podocytes, with hypercellularity and subendothelial immune deposits, confirming an immune-mediated pathophysiology. Ziehl-Neelsen staining did not reveal acid-fast organisms. The patient received a total of 3 weeks of oral prednisolone with subsequent tailing doses, 2 months of pyrazinamide and ethambutol and 6 months of rifampicin and isoniazid with complete resolution of his clinical and radiological signs, though heavy proteinuria persisted, so he was commenced on oral enalapril. This case highlights the potential association of MCGN with tuberculosis in adolescence. Timely recognition and treatment can prevent progression to chronic kidney disease.

The impact of COVID-19 on surgical education: perspectives from Canadian general surgery residents.

Most institutions have mitigated the impact of the COVID-19 pandemic on residency education by transitioning to web-based educational platforms and using innovative solutions, such as surgical video libraries, telehealth clinics, online question banks via social media platforms, and procedural simulations. Here, we assess the perceived impact of COVID-19 on Canadian surgical residency education and discuss the unique challenges in adapting to a virtual format and how novel training methods implemented during the pandemic may be useful in the future of surgical education.

Is ethnicity an appropriate measure of health care marginalization? A systematic review and meta-analysis of the outcomes of diabetic foot ulceration in Aboriginal populations.

BACKGROUND: Aboriginal people have higher prevalence rates of diabetes than non-Aboriginal people in the same geographic locations, and diabetic foot ulcer (DFU) complication rates are also presumed to be higher. The aim of this systematic review and meta-analysis was to compare DFU outcomes in Aboriginal and non-Aboriginal populations. METHODS: We searched PubMed, Embase, CINAHL and the Cochrane Library from inception to October 2018. Inclusion criteria were all types of studies comparing the outcomes of Aboriginal and non-Aboriginal patients with DFU, and studies from Canada, the United States, Australia and New Zealand. Exclusion criteria were patient age younger than 18 years, and studies in any language other than English. The primary outcome was the major amputation rate. We assessed the risk of bias using the ROBINS-I (Risk Of Bias In Non-randomized Studies - of Interventions) tool. Effect measures were reported as odds ratio (OR) with 95% confidence interval (CI). RESULTS: Six cohort studies with a total of 244 792 patients (2609 Aboriginal, 242 183 non-Aboriginal) with DFUs were included. The Aboriginal population was found to have a higher rate of major amputation than the non-Aboriginal population (OR 1.85, 95% CI 1.04-3.31). Four studies were deemed to have moderate risk of bias, and 2 were deemed to have serious risk of bias. CONCLUSION: Our analysis of the available studies supports the conclusion that DFU outcomes, particularly the major amputation rate, are worse in Aboriginal populations than in non-Aboriginal populations in the same geographic locations. Rurality was not uniformly accounted for in all included studies, which may affect how these outcome differences are interpreted. The effect of rurality may be closely intertwined with ethnicity, resulting in worse outcomes.

Meropenem-induced thrombocytopenia: a paediatric case.

Meropenem is a broad-spectrum carbapenem widely used to treat both Gram-positive and negative bacterial infections, including extended-spectrum beta-lactamase-producing microbes. We describe the occurrence of thrombocytopenia and hypersensitivity in a boy receiving intravenous meropenem for intra-abdominal sepsis secondary to perforated appendicitis. The patient developed a pruritic maculopapular rash with occasional petechiae, associated with severe thrombocytopenia, after 7 days of meropenem administration. Investigations for other causes of thrombocytopenia, including possible line sepsis, were unfruitful, and the thrombocytopenia did not resolve until cessation of meropenem. Drug-induced reactions should be considered in children receiving meropenem who present with a rash and thrombocytopenia.
