Experiences and Outcomes of Indigenous Patients Undergoing Bariatric Surgery: a Mixed-Method Scoping Review.

Obesity and type 2 diabetes (T2D) are growing global health concerns. Evidence suggests that Indigenous peoples are at higher lifetime risk of obesity and its associated conditions. Obesity increases the risk of T2D, cardiovascular disease, and all-cause mortality. Bariatric surgery is the most sustained and effective intervention for treating obesity-associated medical problems. This review aims to explore the experiences and outcomes of Indigenous peoples undergoing bariatric surgery in Canada, the USA, Australia, and New Zealand (CANZUS). Analysis of quantitative data revealed that Indigenous patients had fewer bariatric procedures, poorer clinic attendance, similar weight loss outcomes and slightly higher post-operative complication rates. Qualitative data analysis revealed that Indigenous patients living with obesity have a desire to improve their health and quality of life.

Prescription drug usage as measure of comorbidity resolution after bariatric surgery: a population-based cohort study.

BACKGROUND: Obesity is a chronic and progressive disease associated with significant morbidity, mortality, and health-care costs. Bariatric surgery is the most effective intervention for sustainable weight loss and resolution of obesity-related comorbidities. Studies examining comorbidity resolution largely rely on individual self-reported outcomes and electronic record reviews. We present a population-based study looking at prescription medication utilization before and after bariatric surgery as a measure of comorbidity resolution. METHODS: All patients enrolled in the Center for Metabolic and Bariatric Surgery who underwent either gastric bypass or sleeve gastrectomy between 2013 and 2019 in Manitoba were included. Demographic information, follow up, and outpatient prescription dispensation data were obtained from the Manitoba Population Research Data Repository housed at the Manitoba Centre for Health Policy for 5 years pre- and post-surgery. RESULTS: A total of 1184 patients were included. Antidepressants and selective serotonin reuptake inhibitors were the most commonly prescribed classes, and along with thyroid medication, utilization remained stable after bariatric surgery. Proton pump inhibitors and opioid class drugs increased at 1 year after surgery then returned to baseline. Glucose and lipid-lowering medications, including statins, biguanides, sulfonylureas, and insulin, were decreased. Antihypertensives, including ACE inhibitors, calcium channel blockers, angiotensin receptors blockers, thiazides, and beta blockers, similarly decreased. CONCLUSION: This is the first Canadian study employing a provincial-wide prescription database to measure long-term comorbidity resolution after bariatric surgery. The use of administrative data eliminates potential biases and inaccuracies in follow up and self-reported outcomes. Consistent with the literature, prescriptions for the treatment of metabolic syndrome all decreased and were sustained at long-term follow up. Further studies are needed to delineate the effects of altered pharmaceutical utilization on patient quality of life and health-care expenditures.

Impact of a Preoperative Exercise Program on General Fitness in Patients Awaiting Bariatric Surgery: A Pilot Randomized Trial.

Background Evidence supports the association between exercise and outcomes following bariatric surgery. However, there is a lack of knowledge regarding the short-term benefits of preoperative exercise. Objectives The objective of this pilot study was to evaluate the feasibility and functional benefits of a 12-week preoperative exercise program in patients awaiting bariatric surgery. The primary aim was the six-minute walk test (6MWT). The secondary aim of this study included anthropometric measures, strength, and quality of life. Methods A total of 54 patients were enrolled in this pilot randomized controlled study. Of them, 29 patients received standard multidisciplinary preoperative care, while 25 patients participated in a 12-week supervised exercise program in addition to standard preoperative care consisting of strength and aerobic exercises three times per week in a fitness facility. The primary outcome was improvement in 6MWT. Secondary outcomes included other functional outcomes, quality of life, and anthropometric measures. Results Average attendance for the intervention group was 27.2 (75.6%) of 36 sessions. There was a mean improvement of 27 ± 10 meters in the intervention group compared with a reduction of 5 ± 10 meters in the control group (p = 0.003). Patients in the intervention group had significant improvement in all self-reported quality-of-life domains, particularly in the variables related to symptoms, hygiene, and emotions. Conclusions A 12-week preoperative exercise intervention was feasible and showed association with a statistically significant improvement in 6MWT and quality-of-life measures in patients awaiting bariatric surgery. The results of this study will inform sample size calculations and recruitment planning for a future study that will assess the longer-term benefits of a pre-surgical fitness intervention.

Development of consensus-derived quality indicators for laparoscopic sleeve gastrectomy operative reports.

BACKGROUND: Synoptic operative reporting has been used as a solution to the poor quality of narrative reports. The aim of this study was to develop operative report quality indicators for the laparoscopic sleeve gastrectomy and to generate parameters by which these reports can be evaluated and improved. METHODS: A Delphi protocol was used to determine quality indicators for LSG. Bariatric surgeons across Canada were recruited along with key physician stakeholders to participate via a secure web-based platform. Transferrable consensus items for LSG from previously developed Roux-en-Y gastric bypass operative indictors were put forward for consideration. Participants also initially submitted potential QIs. These were grouped by theme. Items were rated on 5-point Likert scales in subsequent rounds. Scores of 70% or higher were used for inclusion and 30% or less denoted exclusion. Elements scoring 30% to 70% agreement were recirculated by runoff in subsequent rounds to generate the final list of quality indicators. RESULTS: Seven bariatric surgeons, representing all regions preforming LSG in Canada, were invited to participate in the Delphi group. Multidisciplinary invitees included one academic minimally invasive/acute care surgeon, one tertiary abdominal radiologist, and one academic gastroenterologist with bariatric expertise. Two rounds were required to achieve consensus. Both rounds achieved a 100% response (10/10). In round 1, forty items reached consensus. In Round 2, an additional 28 items reached consensus, with three items excluded, bringing the total number of quality indicators to 65. CONCLUSION: This study establishes consensus-derived multidisciplinary quality indicators for LSG operative reports. Application of these findings aims to advance the quality and completeness of operative reporting in LSG in order to improve communication of important surgical details and quality measures to the multidisciplinary team involved in bariatric surgery care.

Long-Term Outcomes of Elderly Patients Managed Without Early Cholecystectomy After Endoscopic Retrograde Cholangiopancreatography and Sphincterotomy for Choledocholithiasis.

Background Prophylactic cholecystectomy following endoscopic retrograde cholangiopancreatography with sphincterotomy (ERCP-S) remains the gold standard management of choledocholithiasis. Some clinicians propose ERCP-S alone as the definitive management in the elderly, given perioperative complication risks. This retrospective cohort study aimed to assess the long-term efficacy and safety of non-operative management of choledocholithiasis in adults aged ≥70. Methodology A total of 252 patients aged ≥70 underwent ERCP from 2004 to 2014 at a single institution. The rates of cholecystectomy, ERCP, complications, and mortality were gathered. Data were linked to a provincial health database to capture follow-up visits to alternate hospitals. Predictors of operation, recurrence, and mortality were analyzed using multivariable regression. Results Following ERCP, of the 252 patients, 33 (13.1%) underwent prophylactic cholecystectomy within three months, while 219 (86.9%) were initially managed conservatively. Of the 219 patients, 147 (67.1%) experienced no further choledocholithiasis after conservative management, while 23 (10.5%) patients underwent cholecystectomy. The mean follow-up was 2.9 years. Delayed operative patients were younger (mean age: 77.56 vs. 82.90; p < 0.001) and had lower Charlson Comorbidity Index (CCI) (1.04 vs. 1.84; p = 0.030). When adjusted for age, CCI score, and sex, cholecystectomy was associated with increased survival, with an odds ratio of 0.48 (95% confidence interval = 0.26-0.90; p = 0.021). Perioperative complications occurred in 7/56 (12.5%) patients. Conclusions Recurrent choledocholithiasis is common in elderly patients. Despite recurrent symptoms, these patients are unlikely to undergo cholecystectomy. Surgeons operate on patients with greater life expectancy and fewer comorbidities with high success despite advanced patient age. Future prospective studies should examine objective criteria for prophylactic cholecystectomy in this population, given purported safety and benefits.

Decolonising qualitative research to explore the experiences of Manitoba's urban Indigenous population living with type 2 diabetes mellitus, obesity and bariatric surgery.

INTRODUCTION: Obesity and type 2 diabetes mellitus (T2DM) are growing global health concerns associated with significant morbidity, mortality and healthcare expenditures. Due to histories of colonisation and contemporary marginalisation, Canada's Indigenous populations are disproportionately burdened by obesity, T2DM and many other chronic illnesses. Culturally appropriate research on experiences and outcomes of Indigenous patients undergoing bariatric surgery in Canada is scarce. This qualitative study protocol will use a decolonising approach guided by an Indigenous Elder to explore the perspectives and experiences of urban Indigenous Manitobans with respect to T2DM, obesity and bariatric surgery. This knowledge will guide the development and implementation of culturally sensitive bariatric care. METHODS AND ANALYSIS: Sequential sharing circles (SSCs) and semistructured conversational interviews that have been purposefully designed to be culturally relevant with the guidance of an Indigenous Elder and advisory group (IAG) will be carried out in Winnipeg, Manitoba, Canada. Indigenous adults who are obese (body mass index >35 kg/m2), have T2DM and live in an urban centre will be recruited. Three groups will be investigated: (1) those who have had bariatric surgery; (2) those on the wait list for bariatric surgery and (3) those not associated with a bariatric surgery programme. Each group of 10-12 participants will be guided through a semistructured script led by an Indigenous Elder. Elder-facilitated conversational interviews will also be completed following the SSCs. All content will be audio recorded and transcribed. Thematic analysis will be used to identify emerging patterns using a constructive grounded theory approach. ETHICS AND DISSEMINATION: This study has received ethical approval from the University of Manitoba Health Research Ethics Board. Findings will inform the development and implementation of culturally sensitive programmes at Manitoba's Centre for Metabolic and Bariatric Surgery. Results will be disseminated in peer-reviewed scientific journals, at obesity and Indigenous health conferences, and knowledge sharing ceremonies.

Iron deficiency in bariatric surgery patients: a single-centre experience over 5 years.

Background: As the prevalence of obesity has increased, so too has the demand for bariatric surgery. This study aimed to determine the incidence of postoperative iron deficiency and anemia and the impact of an increased preoperative ferritin target on postoperative outcomes. Methods: Patients undergoing bariatric surgery in Winnipeg from 2010 to 2014 were included in the analysis. Data capture included age, sex and date of surgery and iron, ferritin and hemoglobin levels before surgery and 12 months postoperatively. Before 2014, there was no protocol for preoperative iron supplementation at our centre; in 2014, a more aggressive preoperative iron supplementation program was introduced to target a minimum preoperative ferritin level of 50 mg/L. Data were analyzed using unpaired t tests, paired t tests and χ2 tests. Results: A total of 399 patients were considered; 288 were included in the analysis. The incidence of iron and ferritin deficiency and anemia at 12 months postoperatively was 14.6%, 9.3% and 15.0%, respectively. In patients who underwent surgery before 2014, the 12-month postoperative levels of iron and ferritin were 12.9 mmol/L and 64.0 mg/L, respectively; patients who underwent surgery in 2014 had levels of 18.3 mmol/L and 124.0 mg/L, respectively (all p = 0.001). The 12-month postoperative hemoglobin levels did not significantly differ between the 2 groups. Conclusion: Bariatric surgery performed with more aggressive preoperative iron supplementation is associated with increased iron and ferritin levels at 1 year postoperatively. As this improves overall clinical outcomes by avoiding iron deficiency and anemia, a minimum preoperative ferritin target should be implemented in metabolic and bariatric surgery programs.

Contexte: L'augmentation de la prévalence de l'obésité s'est accompagnée d'un accroissement de la demande de chirurgie bariatrique. La présente étude visait à déterminer l'incidence de la carence en fer et de l'anémie postopératoires ainsi que les conséquences de la hausse du taux cible de ferritine avant l'intervention sur les issues postopératoires. Méthodes: L'analyse a porté sur des patients ayant subi une chirurgie bariatrique à Winnipeg entre 2010 et 2014. Les données recueillies faisaient état de l'âge, du sexe et de la date d'opération des patients, ainsi que de leurs taux de fer, de ferritine et d'hémoglobine avant la chirurgie et 12 mois après celle-ci. Avant 2014, notre centre n'avait pas de protocole de supplémentation préopératoire en fer; en 2014, il a instauré un programme de supplémentation rigoureux visant un taux préopératoire de ferritine d'au moins 50 mg/L. L'analyse des données a été faite au moyen de tests t non appariés, de tests t appariés et de tests χ2. Résultats: Au total, les cas de 399 patients ont été envisagés pour l'analyse, et 288 ont été retenus. L'incidence de la carence en fer, celle de la carence en ferritine et celle de l'anémie 12 mois après la chirurgie étaient de 14,6 %, de 9,3 % et de 15,0 %, respectivement. Chez les patients ayant été opérés avant 2014, les taux de fer et de ferritine à 12 mois étaient de 12,9 mmol/L et de 64,0 mg/L, respectivement, et chez ceux ayant été opérés en 2014, ils étaient de 18,3 mmol/L et de 124,0 mg/L, respectivement (p = 0,001 pour toutes les valeurs). En ce qui concerne le taux d'hémoglobine à 12 mois, aucune différence significative n'a été observée entre les 2 groupes. Conclusion: Les chirurgies bariatriques effectuées après une supplémentation rigoureuse en fer sont associées à des taux accrus de fer et de ferritine 1 an après l'intervention. Sachant que la prévention de la carence en fer et de l'anémie améliore les issues cliniques en général, les programmes de chirurgie métabolique et bariatrique devraient se fixer une cible quant au taux préopératoire minimal de ferritine.

A survey of primary care physician referral to bariatric surgery in Manitoba: access, perceptions and barriers.

BACKGROUND: There is an important disconnect between surgical programs and primary care physicians (PCP) in the delivery of bariatric care. The objective of this study is to assess PCP knowledge and perception of a provincial bariatric surgery program. METHODS: A 32-question, IRB approved, survey was developed by bariatric surgery experts and vetted by local PCPs. A single round of paper surveys was administered to 1,000 PCPs between July and September 2015. Continuous variables were assessed by t-test and categorical variables by Chi-square test. RESULTS: There were 131 survey responses (13.1%). Half (54.2%) of respondents did not feel equipped to counsel their patients on operative management strategies. PCPs counselled on average 11.6%±17.0% of their obese patients on bariatric surgery. Many respondents (58.3%) thought excess weight loss from gastric bypass was less than 40% and most believed there was less than 50% resolution of diabetes (62.4%), hypertension (72.3%), dyslipidemia (77.8%) and obstructive sleep apnea (60.6%). PCPs who referred patients to the bariatric program (71.8%) were more comfortable counselling their patients on bariatric surgery options (56.8% vs. 17.1%, P<0.001) and were more comfortable with post-operative care (67.4% vs. 38.2%, P=0.004). Additionally, these PCPs estimated higher rates of diabetes and hypertension resolution post-bariatric surgery. The predominant perceived barrier to accessing bariatric surgery was wait times (33.3%). CONCLUSIONS: PCPs appear to underestimate the efficacy of bariatric surgery in the treatment of obesity and feel ill-equipped to counsel patients. Further education related to bariatric surgery may improve PCP comfort in counselling and long-term follow-up.

An Alternative Treatment of Pseudogynecomastia in Male Patients After Massive Weight Loss.

BACKGROUND: There has been an increase in body contouring procedures following massive weight loss (MWL), including male breast reduction procedures. Treating male chest deformity after MWL using standard mastopexy techniques often leads to suboptimal results. OBJECTIVES: The authors describe a technique to treat pseudogynecomastia using a modified elliptical excision and nipple-areola complex (NAC) transposition on a thinned inferior dermal pedicle as an alternative to conventional techniques. METHODS: A retrospective chart review from January 2011 to January 2019 identified a total of 14 male patients who underwent excision of pseudogynecomastia using the described technique. RESULTS: Patients were characterized by age, method of weight loss, pre-weight loss body mass index (BMI), post-weight loss BMI, total weight loss, grade of pseudogynecomastia, and concurrent procedures performed. Patients were followed for a period ranging from 3 months to 1.5 years (average, 8.1 months). Pre-weight loss BMI and post-weight loss BMI averaged 52.0 kg/m2 and 29.6 kg/m2, respectively. The average weight lost was 79.72 kg and the average total amount of tissue removed was 2615 g. All patients had concurrent procedures with an average operative time of 274 minutes. Four out of 14 patients (28.6%) experienced minor complications, which included asymmetry, delayed wound healing, seroma, and hyperpigmentation. There were no wound infections, hematomas, flap necrosis, or dysesthesia. CONCLUSIONS: Due to several cosmetic advantages and low complication profile, our technique using a modified elliptical excision and NAC transfer on an inferior dermal pedicle is an attractive option for treating male chest deformity after MWL.

The incidence of iron deficiency anemia post-Roux-en-Y gastric bypass and sleeve gastrectomy: a systematic review.

SETTING: The physiological and anatomical changes that occur as a consequence of bariatric surgery result in macro- and micro-nutritional deficiencies, especially iron deficiency. The reported incidence of iron deficiency and associated anemia after bariatric surgery varies widely across studies. OBJECTIVES: The aim of this systematic review is to quantify the impact of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) on the incidence of iron deficiency. METHODS: Databases including Ovid Medline, Ovid Embase, Helthstar, Scopus, Cochrane (CDSR), LILACS, and ClinicalKey were searched for original articles with additional snowballing search. Search terms included Obesity, nutrient deficiency, iron deficiency, iron deficiency anemia, bariatric surgery, Roux-en-Y gastric bypass, and sleeve gastrectomy. Original articles reporting the incidence of iron deficiency and anemia pre- and post-RYGB and SG from January 2000 to January 2015 with minimum 1-year follow-up were selected. Data extraction from selected studies was based on protocol-defined criteria. RESULTS: There were 1133 articles screened and 20 studies were included in the final analysis. The overall incidence of iron deficiency was 15.2% pre-operatively and 16.6% post-operatively. When analyzed by procedure, the incidence of iron deficiency was 12.9% pre-RYGB versus 24.5% post-RYGB and 36.6% pre-SG versus 12.4% post-SG. The incidence of iron deficiency-related anemia was 16.7% post-RYGB and 1.6% post-SG. Risk factors for iron deficiency were premenopausal females, duration of follow-up, and pre-operative iron deficiency. Prophylactic iron supplementation was reported in 16 studies and 2 studies provided therapeutic iron supplementation only for iron-deficient patients. Iron dosage varied from 7 to 80 mg daily across studies. CONCLUSION: Iron deficiency is frequent in people with obesity and may be exacerbated by bariatric surgery, especially RYGB. Further investigation is warranted to determine appropriate iron supplementation dosages following bariatric surgery. Careful nutritional surveillance is important, especially for premenopausal females and those with pre-existing iron deficiency.

The Impact of an Acute Care Surgical Service on the Quality and Efficiency of Care Outcome Indicators for Patients with General Surgical Emergencies.

Background Acute care surgery (ACS) models address high volumes of emergency general surgery and emergency room (ER) overcrowding. The impact of ACS service model implementation on the quality and efficiency of care (EOC) outcomes in acute appendicitis (AA) and acute cholecystitis (AC) cohorts was evaluated. Methods A retrospective chart review (N=1,229) of adult AA and AC patients admitted prior to (pre-ACS; n=507; three hospitals; 2007) and after regionalization (R-ACS; n=722; one hospital; 2011). Results R-ACS time to ER physician assessment was significantly longer for AA (3.4 ± 2.3 versus 2.4 ± 2.6 hr; p ≤ 0.001). Surgical response times (1.3 ± 1.2 vs 2.6 ± 4.3 hr for AA; 1.8 ± 1.5 vs 4.1 ± 5.0 hr for AC; p ≤ 0.0001) and acquisition of imaging (4.1 ± 4.1 vs 6.9 ± 9.9 hr for AA, p ≤ 0.0001; 7.8 ± 1.9 vs 13.2 ± 18.5 hr for AC, p ≤ 0.008) occurred significantly faster with R-ACS. R-ACS resulted in a significant increase in night-time appendectomies (21.7% vs 11.1%; p ≤ 0.002), perforated appendices (29.1 % vs 18.9 %; p ≤ 0.006), 30-day readmissions (4.56% vs 0.82%; p ≤ 0.01), and lower rate of intraoperative complications for AC patients (2.78% vs 7.69%; p ≤ 0.02). Conclusions Despite the increased volume of patients seen with the implementation of R-ACS, surgical assessments and diagnostic imaging were significantly more prompt. EOC measures were maintained. Worse AA outcomes highlight areas for improvement in delivering R-ACS.

Fellow and Attending Surgeon Operative Notes are Deficient in Reporting Established Quality Indicators for Roux-en-Y Gastric Bypass: A Preliminary Retrospective Analysis of Operative Dictation.

Introduction Surgeons must dictate the important components of any invasive procedure in a comprehensive, yet concise, operative report. This documentation is vital for communicating operative events and has implications for providing additional healthcare and planning future operations. The quality of surgical care may be impaired in the absence of such communication. Evidence suggests that the quality of reports dictated by trainees and surgeons is poor despite its importance. This investigation analyzed and compared the quality of fellow and staff surgeon Roux-en-Y Gastric Bypass (RYGB) narrative dictations against validated and reliable quality indicators (QIs) for this procedure. Methods A total of 40 bariatric fellow reports and 40 attending RYGB narrative reports were retrospectively analyzed. Results Fellows had a mean completion of 66.4% +/- 3.1% as compared to 61.5% +/- 7.6% for attendings (p<0.0001). Fellows statistically outperformed attendings on all subsections except patient, closure, and postoperative details. Attendings statistically outperformed fellows on closure details only (63.8 +/- 7.5 vs 50.5 +/- 12.0, p=0.002). Conclusions Bariatric surgery trainees outperform attending surgeons in RYGB operative dictation. The clinical significance of this difference is unknown. However, both groups are deficient in reporting at least one-third of items deemed essential to RYGB operative reporting. This indicates a need for further education in RYGB dictation for practicing surgeons and trainees. It also lends interest in exploring alternative forms of operative communication such as synoptic operative reporting in bariatric surgery.

Effect of Roux-en-Y gastric bypass on pharmacologic dependence in obese patients with type 2 diabetes

Background: More than half the diabetes-related health care costs in Canada relate to drug costs. We aimed to determine the effect of Roux-en-Y gastric bypass (RYGB) on the use of insulin and orally administered hypoglycemic medications in patients with diabetes. We also looked to determine overall cost savings with the procedure. Methods: We reviewed the bariatric clinic records of all patients with a confirmed diagnosis of type 2 diabetes mellitus who underwent RYGB between 2010/11 and 2014/15. Percentage estimated weight loss was recorded at 1 year, along with reductions in glycated hemoglobin (HbA1c) level and use of oral hypoglycemic therapy and insulin. We estimated medication costs using Manitoba-specific pricing data. Results: Fifty-two patients with at least 12 months of complete follow-up data were identified. The mean percentage estimated weight loss was 50.2%. The mean HbA1c level decreased from 7.6% to 6.0%, the mean number of orally administered hypoglycemics declined from 1.6 to 0.2, and the number of patients receiving insulin decreased from 18 (35%) to 3 (6%) (all p < 0.001). The rate of resolution of type 2 diabetes was 71%. Estimated mean annual per-patient medication costs decreased from $508.56 to $79.17 (p < 0.001). Potential overall health care savings could total $3769 per patient in the first year, decreasing to $1734 at 10 years. Conclusion: Roux-en-Y gastric bypass resulted in significant improvement in diabetic control, with a reduction in hypoglycemic medication use and associated costs in the early postoperative period. Potentially, large indirect and direct cost savings can be realized in the longer term.

Contexte: Plus de la moitié des coûts des soins de santé liés au diabète au Canada sont générés par les médicaments. Nous avons voulu déterminer l'effet de la dérivation gastrique de Roux-en-Y sur l'utilisation des agents hypoglycémiants oraux et de l'insuline chez les patients diabétiques. Nous avons aussi cherché à déterminer l'ensemble des économies associées à cette intervention. Méthodes: Nous avons passé en revue les dossiers cliniques bariatriques de tous les patients ayant un diagnostic confirmé de diabète de type 2 qui ont subi une dérivation gastrique de Roux-en-Y entre 2010­2011 et 2014­2015. La perte de poids ­ estimée en pourcentage ­ a été notée après un an, ainsi que les réductions des taux d'hémoglobine glyquée (HbA1c) et du recours aux hypoglycémiants oraux et à l'insuline. Nous avons estimé les coûts des médicaments à partir des données de tarification du Manitoba. Résultats: Cinquante-deux patients pour lesquels on disposait d'au moins 12 mois de données de suivi complètes ont été retenus. La perte de poids moyenne estimée en pourcentage était de 50,2 %. Le taux moyen d'HbA1c a diminué de 7,6 % à 6,0 %, le nombre moyen de comprimés d'hypoglycémiants oraux est passé de 1,6 à 0,2, et le nombre de patients sous insuline a diminué de 18 (35 %) à 3 (6 %) (tous p < 0,001). Le taux de résolution du diabète de type 2 était de 71 %. Le coût annuel moyen estimé des médicaments par patient est passé de 508,56 $ à 79,17 $ (p < 0,001). Les économies potentielles globales pour le système de santé pourraient totaliser 3769 $ par patient au cours de la première année, puis passer graduellement à 1734 $ au cours des 10 années suivantes. Conclusion: La dérivation gastrique de Roux-en-Y a permis d'améliorer significativement le contrôle du diabète, ainsi que de réduire le recours aux hypoglycémiants et les coûts associés au début de la période postopératoire. À plus long terme, d'importantes économies sur le plan des coûts indirects et directs pourraient potentiellement être réalisées.

Impact of acute care surgery on timeliness of care and patient outcomes: a systematic review of the literature

Background: Dedicated emergency general surgery (EGS) service models were developed to improve efficiency of care and patient outcomes. The degree to which the EGS model delivers these benefits is debated. We performed a systematic review of the literature to identify whether the EGS service model is associated with greater efficiency and improved outcomes compared to the traditional model. Methods: We searched MEDLINE, Embase, Scopus and Web of Science (Core Collection) databases from their earliest date of coverage through March 2017. Primary outcomes for efficiency of care were surgical response time, time to operation and total length of stay in hospital. The primary outcome for evaluating patient outcomes was total complication rate. Results: The EGS service model generally improved efficiency of care and patient outcomes, but the outcome variables reported in the literature varied. Conclusion: Development of standardized metrics and comprehensive EGS databases would support quality control and performance improvement in EGS systems.

Contexte: Des modèles dédiés de services de chirurgie générale d'urgence (CGU) ont été développés pour améliorer l'efficience des soins et les résultats chez les patients. On ne s'entend toutefois pas sur l'ampleur des bénéfices conférés par le modèle CGU. Nous avons procédé à une revue systématique de la littérature afin de vérifier si le modèle CGU est associé à une plus grande efficience et à de meilleurs résultats comparativement au modèle classique. Méthodes: Nous avons interrogé les bases de données MEDLINE, Embase, Scopus et Web of Science (collection centrale) depuis la plus ancienne couverture du sujet et jusqu'à mars 2017. Les paramètres principaux pour l'efficience des soins étaient le temps de réponse, le délai avant l'intervention et la durée totale du séjour hospitalier. Le paramètre principal pour l'évaluation des résultats chez les patients était le taux de complications total. Résultats: Le modèle de service CGU améliore généralement l'efficience des soins et les résultats chez les patients, mais dans la littérature, les paramètres mesurés varient. Conclusion: Le développement de paramètres standardisés et de bases de données globales sur la CGU appuierait le contrôle de la qualité et l'amélioration du rendement des systèmes CGU.

Advancement in the quality of operative documentation: A systematic review and meta-analysis of synoptic versus narrative operative reporting.

BACKGROUND: The operative report is vital for patients and central to surgical quality assessment. Narrative operative reports are often poor quality. Synoptic reporting can improve documentation. The objective was to identify and appraise studies comparing synoptic and narrative operative reporting. DATA SOURCES: A systematic review of the literature was performed. The primary outcome was completion of critical elements for an operative report. Additional secondary outcomes were measured. Meta-analysis was performed where possible. Quality analysis was performed using Newcastle-Ottawa Scale (NOS). RESULTS: 1471 citations were identified; 16 studies included. Mean NOS was 7.09 out of 9 (+/-- SD 1.73). Meta-analysis demonstrated that synoptic reporting was significantly more complete (SMD 1.70, 95% CI 1.13 to 2.26; I2 98%). Completion time was shorter with synoptic reporting (mean difference -0.86, 95% CI -1.17 to -0.55). Secondary outcomes favoured synoptic reporting. CONCLUSIONS: Synoptic reporting platforms outperform narrative reporting and should be incorporated into surgical practice.

Canadian general surgery residents' need formal curricula and objective performance assessments in gastrointestinal endoscopy training: a program director census.

INTRODUCTION: Methods of developing and determining General Surgery (GS) residents' competency in gastrointestinal endoscopy in Canada are not currently standardized. This study aimed to assess the status of gastrointestinal endoscopy training in Royal College of Physicians and Surgeons of Canada (RCPSC) GS residency programs. METHODS: A 35-question survey was developed using GS gastrointestinal endoscopy curricula guidelines. All 17 RCPSC GS program directors were contacted to complete the questionnaire via the web-based SurveyMonkey.ca® platform. RESULTS: All 17 program directors completed the survey (100% response rate). Program demographics Sixteen programs reported having dedicated endoscopy rotations with a mean duration of 2.8 months (range 0-4, SD 1.1). Upon completion of dedicated endoscopy rotations, four programs (25%) reported having formal skills assessments and three (18.8%) reported formal knowledge examinations. All programs required endoscopy procedures be logged throughout residency, but only three (21.4%) included quality indicators. Only one program required residents to obtain Fundamentals of Endoscopic Surgery certification. Program outcomes The reported estimated mean number of procedures during residents' endoscopy rotations was 82 (range 10-150, standard deviation 33.6) gastroscopies and 156 (40-350, 76.3) colonoscopies. The mean number of procedures during residents' entire residencies was 150 (20-400, 98.6) gastroscopies and 241 (50-500, 76.3) colonoscopies. The number of months of dedicated endoscopy training significantly correlated with the total estimated number of endoscopic procedures performed (ρ = 0.67, p = 0.02). Eleven program directors (73.3%) believed residents were prepared for independent endoscopy practice, while four disagreed (26.7%). Program directors' perceptions of residents' preparedness were significantly correlated with the number of endoscopic procedures performed by residents (p < 0.01) but not the robustness of the endoscopy curriculum (p = 0.72). CONCLUSION: Endoscopy training in RCPSC GS residency programs is highly variable. Program directors' perceptions of residents' competency appear to be significantly correlated with procedure numbers and few have adopted formal curricula and performance assessments.

Synoptic operative reporting: assessing the completeness, accuracy, reliability, and efficiency of synoptic reporting for Roux-en-Y gastric bypass.

OBJECTIVE: Synoptic reporting (SR) is one solution to improve the quality of operative reports. However, SR has not been investigated in bariatric surgery despite an identified need by bariatric surgeons. SR for RYGB was developed using quality indicators (QIs) established by a national Delphi process. The objective of this study is to assess the completeness, accuracy, reliability, and efficiency of synoptic versus narrative operative reports (NR) in Roux-en-Y gastric bypass (RYGB). METHODS: A NR and SR were completed on 104 consecutive RYGBs. Two evaluators independently compared the reports to QIs. Completeness and accuracy measures were determined. Reliability was calculated using Bland-Altman plots and 95% limits of agreement (LOA). Time to complete SR and NR was also compared. RESULTS: The mean completion rate of SR was 99.8% (±SD 0.98%) compared to 64.0% (±SD 6.15%) for NR (t = 57.9, p < 0.001). All subsections of SR were >99% complete. This was significantly higher than for NR (p < 0.001) except for small bowel division details (p = 0.530). Accuracy was significantly higher for SR than NR (94.2% ± SD 4.31% vs. 53.6% ± SD 9.82%, respectively, p < 0.001). Rater agreement was excellent for both SR (0.11, 95% LOA -0.53 to 0.75) and NR (-0.26, 95% LOA -4.85 to 4.33) (p = 0.242), where 0 denotes perfect agreement. SR completion times were significantly shorter than NR (3:55 min ± SD 1:26 min and 4:50 min ± SD 0:50 min, respectively, p = 0.007). CONCLUSION: The RYGB SR is superior to NR for completeness and accuracy. This platform is also both reliable and efficient. This SR should be incorporated into clinical practice.
