RESUMEN

BACKGROUND: Patients with oropharyngeal squamous cell carcinoma (OPSCC) treated with radiation-based therapy suffer from short- and long-term toxicities that affect quality of life (QOL). Transoral robotic surgery (TORS) has an established role in the management of early OPSCC but adjuvant treatment is often indicated postoperatively due to the high incidence of nodal metastasis associated with advanced human papillomavirus (HPV)-related OPSCC. To overcome the need for adjuvant radiation therapy (RT), neoadjuvant chemotherapy followed by TORS and neck dissection (ND) is proposed. This study aimed to assess if QOL in HPV-associated OPSCC receiving neoadjuvant chemotherapy followed by TORS and ND returns to baseline within 12 months of completing treatment. METHODS: A 12 month longitudinal study was carried out at McGill University Health Centre in Montreal, Canada, among a convenience sample of patients with American Joint Committee on Cancer Seventh Edition stage III and IVa HPV-related OPSCC who were treated with neoadjuvant chemotherapy followed by TORS and ND. QOL data were obtained pretreatment and at 1, 3, 6, and 12 months following treatment completion using the European Organisation for Research and Treatment of Cancer Core and Head and Neck extension modules. Paired t tests and mixed models for repeated measures analysis were used to assess changes in QOL from baseline to 12 months postoperatively and over time, respectively. RESULTS: Nineteen of 23 patients (median age 58 years) who received the study treatment fulfilled the eligibility criteria. OPSCC subsites were palatine tonsil (n = 12) and base of tongue (n = 7). All 19 patients were treated per protocol and none required adjuvant RT as per pathology review and protocol requirements at a postoperative multidisciplinary team tumor board discussion. No significant differences were found when comparing 12 month QOL follow-up scores to pretreatment scores in measures that would likely be affected by RT [eg, swallowing (P = .7), social eating (P = .8), xerostomia (P = .9)]. CONCLUSION: In HPV-related OPSCC, neoadjuvant chemotherapy followed by TORS and ND as definitive treatment is associated with excellent QOL outcomes. Postoperative QOL scores returned to baseline by 3 months and were maintained for all measures, indicating a return to normal function.

RESUMEN

OBJECTIVE: We conducted a multicenter study to assess treatments and outcomes in a national cohort of infants with congenital ovarian cysts. SUMMARY BACKGROUND DATA: Wide variability exists in the treatment of congenital ovarian cysts. The effects of various treatment strategies on outcomes, specifically ovarian preservation, are not known. METHODS: Female infants diagnosed with congenital intra-abdominal cysts between 2013 and 2017 at 10 Canadian pediatric surgical centers were retrospectively evaluated. Sonographic characteristics, median time to cyst resolution, incidence of ovarian preservation, and predictors of surgery were evaluated. Subgroup analyses were performed in patients with complex cysts and cysts ≥40 mm in diameter. RESULTS: The study population included 189 neonates. Median gestational age at diagnosis and median maximal prenatal cyst diameter were 33 weeks and 40 mm, respectively. Cysts resolved spontaneously in 117 patients (62%), 14 (7%) prenatally, and the remainder at a median age of 124 days. Intervention occurred in 61 patients (32%), including prenatal aspiration (2, 3%), ovary sparing resection (14, 23%), or oophorectomy (45, 74%). Surgery occurred at a median age of 7.4weeks. Independent predictors of surgery included postnatal cyst diameter ≥40 mm [odds ratio (OR) 6.19, 95% confidence interval (CI) 1.66-35.9] and sonographic complex cyst character (OR 63.6, 95% CI 10.9-1232). There was no significant difference in the odds of ovarian preservation (OR 3.06, 95% CI 0.86 -13.2) between patients who underwent early surgery (n = 22) and those initially observed for at least 3 months (n = 131). CONCLUSIONS: Most congenital ovarian cysts are asymptomatic and spontaneously resolve. Early surgical intervention does not increase ovarian preservation.

RESUMEN

PURPOSE: The origin of congenital abdominal cysts in the female fetus often dictates management. While most arise from the ovary and are often managed non-operatively, some are non-ovarian and are frequently removed. We analyzed a national sample of female infants with congenital abdominal cysts to elucidate prenatal and postnatal factors associated with the diagnosis of a non-ovarian cyst. METHODS: A retrospective cohort study of female infants who were prenatally diagnosed with abdominal cysts between 2013 and 2017 at 10 Canadian pediatric surgical centres was performed. Clinical characteristics, pre- and postnatal sonographic findings, and cyst trajectories were compared between patients with proven ovarian etiology and those with cysts arising from other organs. RESULTS: Of 185 infants with prenatally diagnosed abdominal cysts, 22 (12%) were non-ovarian, five of which had clear non-ovarian organ of origin on prenatal ultrasound. Comparison of the other 17 cysts with 163 congenital ovarian cysts showed the following factors to be associated with a non-ovarian origin: earlier gestational age at diagnosis (23.5 vs 33.5 weeks, p <0.001), smaller diameter on first prenatal ultrasound (15.8 vs. 39.7 mm, p <0.001), change in sonographic character from simple to complex (87% vs 22%, p <0.001), and postnatal sonographic characteristics of complex cyst (87% vs. 48%, p = 0.004). CONCLUSION: Clear organ of origin, diagnosis earlier in gestation, smaller initial prenatal cyst diameter, and sonographic cyst character change differentiate congenital non-ovarian cysts from their ovarian counterparts. These characteristics may be used to guide diagnosis and management.

RESUMEN

OBJECTIVES/HYPOTHESIS: To identify barriers in access to care for head and neck cancer (H&NC) patients in low- and middle-income countries (LMICs), specifically within Dakar, Senegal, using both quantitative and qualitative data. STUDY DESIGN: Descriptive observational study. METHODS: Patients with H&NC were selected from two independent university hospitals in Dakar, Senegal. A mixed-methods descriptive study was performed using a specifically tailored questionnaire and a focused ethnographic qualitative approach to identify factors that delay patient presentation, referral, and treatment. Quantitative data were analyzed using descriptive statistics and qualitative using a deductive approach based on a systematic review of the literature. RESULTS: Thirty-three patients with a mean age of 57.8 years were included. Presentation delay was 5.7 months, mainly attributed to cost of consultation (39%), waiting time at doctor's office (15%), and distance to healthcare facility (12%). Referral delay greater than 3 months was observed in 60% of participants, secondary to misdiagnosis and lack of appropriate referral. Treatment delay was associated with limited local treatment capacity and securing cost of treatment. Cost of transportation impacted all delays. CONCLUSIONS: This work used an evidence-based approach to identify barriers in access to care for H&NC patients in sub-Saharan Africa. It suggests the feasibility and transferability of this methodology which combined a quantitative approach based on the literature with a qualitative analysis. Insight provided by this study will be used to guide development of implementation strategies for early detection of H&NC in LMICs. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:1219-1223, 2022.

RESUMEN

BACKGROUND: Mobile health (mHealth) technologies are innovative solutions for delivering instructions to patients preparing for colonoscopy. OBJECTIVE: To systematically review the literature evaluating the effectiveness of mHealth technologies supporting colonoscopy preparation on patient and clinical outcomes. METHODS: MEDLINE, EMBASE, CINAHL and CENTRAL were searched for randomized controlled trials (RCTs) that evaluated the effectiveness of mHealth technologies for colonoscopy preparation on patient and clinical outcomes. Two reviewers independently assessed study eligibility, extracted data, and appraised methodological quality using the Cochrane Risk-of-Bias tool. Data were pooled using random effects models and when heterogeneity, assessed using I2, was statistically significant, a qualitative synthesis of the data was performed. Publication bias was assessed using a funnel plot. RESULTS: Ten RCTs (3,383 participants) met inclusion criteria. MHealth interventions included smartphone apps, SMS text messages, videos, camera apps, and a social media app. Outcomes were bowel cleanliness quality, user satisfaction, colonoscopy quality indicators (cecal intubation time, withdrawal time, adenoma detection rate), adherence to diet, and cancellation/no-show rates. MHealth interventions were associated with better bowel cleanliness scores on the Boston Bowel Preparation Scale [standardized mean difference (SMD) 0.57, 95%CI 0.37-0.77, I2 = 60%, p = 0.08] and the Ottawa Bowel Preparation Scale [SMD -0.39, 95%CI -0.59-0.19, I2 = 45%, p = 0.16], but they were not associated with rates of willingness to repeat the colonoscopy using the same regimen [odds ratio (OR) 1.88, 95%CI 0.85-4.15, I2 = 48%, p = 0.12] or cancellations/no-shows [OR 0.96, 95%CI 0.68-1.35, I2 = 0%]. Most studies showed that adequate bowel preparation, user satisfaction and adherence to diet were better in the intervention groups compared to the control groups, while inconsistent findings were observed for the colonoscopy quality indicators. All trials were at high risk of bias for lack of participant blinding. Visual inspection of a funnel plot revealed publication bias. CONCLUSIONS: MHealth technologies show promise as a way to improve bowel cleanliness, but trials to date were of low methodological quality. High-quality research is required to understand the effectiveness of mHealth technologies on colonoscopy outcomes.

RESUMEN

OBJECTIVE: Melanoma is the most lethal of skin cancers; however, survival rates are excellent if the tumor is detected early. Clinical practice guidelines for melanoma follow-up care recommend regular skin self-examination (SSE) for individuals at high risk for melanoma. The current analyses tested whether self-efficacy for SSE and intention to perform SSE mediate the relationship between physician support for SSE and SSE behavior among a sample of melanoma patients. METHODS: We ran a serial mediation model on a cross-sectional sample of melanoma patients (n = 154) drawn from an observational study with longitudinal follow-up. RESULTS: Self-efficacy and intention to perform SSE sequentially mediated the relationship between physician support and SSE behaviors (ß = .31, t(152) = 3.61, p < .001 without mediators versus ß = .11, t(150) = 1.50, p = .14 with mediators), as supported by a significant total indirect effect (ß = .21, [95 % CI = .08-.35]). CONCLUSION: Self-efficacy for SSE and intention to perform SSE together explain the link between perceived physician support for SSE and the practice of SSE. PRACTICE IMPLICATIONS: Physician communication about the importance of SSE plays an important role in encouraging patient adherence to SSE recommendations and, thus, supporting early detection efforts.

RESUMEN

OBJECTIVE: To determine the effect of current smoking status on 30-day postoperative adverse events in patients undergoing otologic surgery. STUDY DESIGN: Retrospective cohort study. SETTING: Database of the American College of Surgeons National Surgical Quality Improvement Program from 2006 to 2016. SUBJECTS AND METHODS: Adult patients undergoing middle ear and mastoid surgery were included. Preoperative smoking status was determined, and adverse events within 30 days of surgery were recorded. Descriptive statistics were used to characterize the study sample. Multivariable logistic regression was performed to identify the association between sociodemographic and clinical variables and postoperative adverse events. Population-attributable fractions were then calculated. RESULTS: A total of 10,684 patients who underwent otologic surgery were included, of whom 2036 (19.1%) were smokers. The most commonly performed surgery was tympanoplasty with and without ossicular chain reconstruction, followed by canal wall up tympanomastoidectomy. Adverse events occurred in 221 (2.1%) patients; the most common was superficial wound infections (n = 99, 0.9%). In smokers, the odds ratio for any adverse event was 1.97 (95% CI, 1.42-2.71). The odds ratios (95% CIs) for superficial wound infections, wound dehiscence, and 30-day readmission among smokers were 1.89 (1.32-2.86), 3.92 (1.26-11.60), and 1.84 (1.15-2.87), respectively. The population-attributable fraction for any adverse event in smokers was 15.5%. CONCLUSIONS: In patients undergoing otologic surgery, smokers are more likely than nonsmokers to have postoperative adverse events-in particular, wound infections, wound dehiscence, and readmission to hospital.

RESUMEN

BACKGROUND: The preparation for colonoscopy is elaborate and complex. In the context of colorectal cancer screening, up to 11% of patients do not keep their colonoscopy appointments and up to 33% of those attending their appointments have inadequately cleansed bowels that can delay cancer diagnosis and treatment. A smartphone app may be an acceptable and wide-reaching tool to improve patient adherence to colonoscopy. OBJECTIVE: The aim of this qualitative study was to employ a user-centered approach to design the content and features of a smartphone app called colonAPPscopy to support individuals preparing for their colonoscopy appointments. METHODS: We conducted 2 focus group discussions (FGDs) with gastroenterology patients treated at the McGill University Health Centre in Montreal, Canada. Patients were aged 50 to 75 years, were English- or French-speaking, and had undergone outpatient colonoscopy in the previous 3 months; they did not have inflammatory bowel disease or colorectal cancer. FGDs were 75 to 90 min, conducted by a trained facilitator, and audiotaped. Participants discussed the electronic health support tools they might use to help them prepare for the colonoscopy, the content needed for colonoscopy preparation, and the features that would make the smartphone app useful. Recordings of FGDs were transcribed and analyzed using thematic analysis to identify key user-defined content and features to inform the design of colonAPPscopy. RESULTS: A total of 9 patients (7 male and 2 female) participated in one of 2 FGDs. Main content areas focused on bowel preparation instructions, medication restrictions, appointment logistics, communication, and postcolonoscopy expectations. Design features to make the app useful and engaging included minimization of data input, reminders and alerts for up to 7 days precolonoscopy, and visual aids. Participants wanted a smartphone app that comes from a trusted source, sends timely and tailored messages, provides reassurance, provides clear instructions, and is simple to use. CONCLUSIONS: Participants identified the need for postcolonoscopy information as well as reminders and alerts in the week before colonoscopy, novel content, and features that had not been included in previous smartphone-based strategies for colonoscopy preparation. The ability to tailor instructions made the smartphone app preferable to other modes of delivery. Study findings recognize the importance of including potential users in the development phase of building a smartphone app.

RESUMEN

BACKGROUND: Randomized controlled trials are the gold standard in medical and surgical research to assess the efficacy of therapeutic interventions. The reporting of these trials should be of high quality to allow readers' appropriate interpretation and application. METHODS: The objectives of our study were to assess the extent to which the recent Otolaryngology - Head and Neck Surgery (ORL-HNS) randomized control trials in the top nine journals and in the top Canadian journal comply with the Consolidated Standards of Reporting Trials (CONSORT) statement, and to identify the CONSORT items most in need of improvement. Based on the impact factor and circulation number of 2014, the top nine Otolaryngology journals and the top Canadian Otolaryngology journal were selected and were searched to identify RCTs published in English and between 2010 and 2014. Two authors independently reviewed and extracted data using a standardized data extraction form constructed with the help of a medical librarian. Our outcome was to assess the adherence of articles reporting to the CONSORT items. Descriptive statistics were used. RESULTS: One hundred and eighty-two Otolaryngologic RCTs were identified in the top nine international journals and in the top Canadian journal. The inter-rater reliability between two raters was 0.32. The extent of adherence to CONSORT Statement ranged from 25 to 93.5% with a mean of 59.0% and a median of 59.4%. Only 6.5% of RCTs described the individual responsible for enrolling and assigning subjects and method of randomization; 32.4% reported the estimated effect size and precision; 40.6% reported a sample size calculation and 32.4% mentioned external validity or implications of the findings. CONCLUSION: Findings revealed that the reporting of RCTs in the top nine ORL-HNS journals and in the top Canadian ORL-HNS journal is suboptimal. The quality of reporting can be improved by addressing the three CONSORT items found most deficient in this study namely, sample size calculations, estimated effect size and precision, and external validity.

RESUMEN

We sought to determine, among outpatients at one university hospital endoscopy center, rates of self-reported minor adverse events (MAEs) at 2, 14, and 30 days postcolonoscopy and to identify predictors of MAEs at Day 2 postcolonoscopy. A single-center longitudinal cohort study with follow-ups at Days 2, 14, and 30 postcolonoscopy was conducted in Montreal, Canada. Baseline self-report data included patient age, gender, gastrointestinal discomforts and other discomforts in the preceding month, and comorbidity. Intracolonoscopy procedures and the method of insufflation were obtained from endoscopy reports. Minor adverse event data were obtained by either phone or Internet survey. Multivariate logistic regression was used to identify predictors of MAEs at Day 2. Of 705 individuals approached, 420 (mean age = 58.7 years; SD = 8.4, 45.7% female) were eligible and consented to study participation, and 378 (90%) participated in at least one follow-up. At Days 2, 14, and 30, 86 (25.1%), 46 (13.7%), and 13 (3.1%) patients, respectively, experienced at least one MAE. At the Day 30 follow-up, 2 (0.53%) patients reported having experienced a serious adverse event. The multivariable analysis results showed that screening compared with nonscreening colonoscopy was protective for MAEs at 2 days (OR = 0.5, 95% CI [0.3, 0.9]). We found that 25% of patients experienced at least one MAE at 2 days postcolonoscopy, and screening compared with nonscreening colonoscopy patients were half as likely to experience these early MAEs. Nurses may use these findings to educate and reassure patients about colonoscopy risks. Large, longitudinal multicenter studies are needed to corroborate our findings.

RESUMEN

BACKGROUND AND AIM: Diagnostic and management guidelines for vitamin B12 (cobalamin, Cbl) deficiency in inflammatory bowel disease (IBD) are lacking. True deficiency is defined as Cbl concentrations below reference range combined with elevated methylmalonic acid (MMA) concentrations. Studies analyzing Cbl status in IBD use only Cbl concentrations without confirmatory MMA. This study aims to determine the proportion of IBD patients with Cbl concentrations below reference range and their predisposing clinical and genetic characteristics. We then compared this to the proportion with true deficiency. PATIENTS AND METHODS: In a prospective observational pilot study of adult IBD outpatients, Cbl concentrations, MMA levels, and fucosyltransferase 2 mutations were measured at clinic visits. RESULTS: A total of 66 Crohn's disease (CD) and 30 ulcerative colitis (UC) patients were recruited. Mean Cbl concentrations (pmol/l) in CD (253.7) were not significantly lower than UC (320.5, P=0.24). Serum Cbl below reference range (<148) was observed in 7.6 and 10% of CD and UC patients, respectively (P=0.70). True deficiency in CD and UC was 3 and 3.3%, respectively (P=1.0). Patients with ileal resections more than 30 cm had lower mean Cbl concentrations (177, P=0.02) and a trend toward higher proportions with Cbl levels below reference range (40%, P=0.06), but not increased deficiency rates (0%, P=1.0). Disease location, severity, and fucosyltransferase 2 mutations were not associated with altered Cbl status. CONCLUSION: True Cbl deficiency was rare in IBD patients in this study. A disparity in Cbl status exists when confirmatory MMA levels are used compared with Cbl concentrations alone. Asymptomatic IBD patients with low serum Cbl require confirmatory tests to guide management and avoid unnecessary treatment.

RESUMEN

BACKGROUND & AIMS: Hepatic steatosis (HS) seems common in patients infected with human immunodeficiency virus (HIV). However, the relative effect of HIV, as well as hepatitis C virus (HCV) in those co-infected, and the influence of HS on liver fibrosis progression are unclear. METHODS: The LIVEr disease in HIV (LIVEHIV) is a Canadian prospective cohort study using transient elastography and associated controlled attenuation parameter (CAP) to screen for HS and liver fibrosis, in unselected HIV-infected adults. HS progression was defined as development of any grade HS (CAP ⩾248dB/m), or transition to severe HS (CAP >292dB/m), for those with any grade HS at baseline. Fibrosis progression was defined as development of significant liver fibrosis (liver stiffness measurement [LSM] >7.1kPa), or transition to cirrhosis (LSM >12.5kPa) for those with significant liver fibrosis at baseline. Cox regression analysis was used to assess predictors of HS and fibrosis progression. RESULTS: A prospective cohort study was conducted, which included 726 HIV-infected patients (22.7% HCV co-infected). Prevalence of any grade HS did not differ between HIV mono-infected and HIV/HCV co-infected patients (36.1% vs. 38.6%, respectively). 313 patients were followed for a median of 15.4 (interquartile range 8.5-23.0) months. The rate of HS progression was 37.8 (95% confidence interval [CI] 29.2-49.0) and 21.9 (95% CI 15.6-30.7) per 100 person-years in HIV mono-infection and HIV/HCV co-infection, respectively. HCV co-infection was an independent negative predictor of HS progression (adjusted hazard ratio [aHR] 0.50, 95% CI 0.28-0.89). HS predicted liver fibrosis progression in HIV mono-infection (aHR 4.18, 95% CI 1.21-14.5), but not in HIV/HCV co-infection. CONCLUSION: HS progresses faster and is associated with liver fibrosis progression in HIV mono-infection but not in HIV/HCV co-infection. Lay summary: Fatty liver is the most frequent liver disease in Western countries. People living with HIV seem at high risk of fatty liver due to frequent metabolic disorders and the long-term effects of antiretroviral therapy. However, due to the invasiveness of liver biopsy, the traditional method of diagnosing fatty liver, there are few data regarding its frequency in people living with HIV. In this study, we used a non-invasive diagnostic tool to analyze the epidemiology of fatty liver in 726 HIV+ patients. We found that fatty liver affects over one-third of people living with HIV. When followed over time, we found that HIV+ patients without HCV co-infection develop fatty liver more frequently than those co-infected with HCV.

RESUMEN

Patient autonomy is a central value in medicine and critical component of adherence to medical advice. This article reports on a validation of the 6-item version of the Health Care Climate Questionnaire (HCCQ), a measure of autonomy support in health care settings, in a sample of 242 melanoma patients. The HCCQ showed excellent internal consistency (α = .91), structural validity (Tucker-Lewis index = .99; comparative fit index = .99; root mean square error of approximation = .06, 90 per cent confidence interval (.00, .11); standardized root mean square residual = .02; χ2 (8, N = 235) = 13.99, p = .08) and construct validity (92.31% of hypothesized correlations with other measures confirmed). Acceptable 3-month test-retest reliability was observed (r = .55, p < .001; intraclass correlation coefficient (A, 1) = .54, p < .001). The French version was found equivalent to the English version.

RESUMEN

Background. The United Kingdom Global Rating Scale (GRS-UK) measures unit-level quality metrics processes in digestive endoscopy. We evaluated the psychometric properties of its Canadian version (GRS-C), endorsed by the Canadian Association of Gastroenterology (CAG). Methods. Prospective data collection at three Canadian endoscopy units assessed GRS-C validity, reliability, and responsiveness to change according to responses provided by physicians, endoscopy nurses, and administrative personnel. These responses were compared to national CAG endoscopic quality guidelines and GRS-UK statements. Results. Most respondents identified the overarching theme each GRS-C item targeted, confirming face validity. Content validity was suggested as 18 out of 23 key CAG endoscopic quality indicators (78%, 95% CI: 56-93%) were addressed in the GRS-C; statements not included pertained to educational programs and competency monitoring. Concordance ranged 75-100% comparing GRS-C and GRS-UK ratings. Test-retest reliability Kappa scores ranged 0.60-0.83, while responsiveness to change scores at 6 months after intervention implementations were greater (P < 0.001) in two out of three units. Conclusion. The GRS-C exhibits satisfactory metrics, supporting its use in a national quality initiative aimed at improving processes in endoscopy units. Data collection from more units and linking to actual patient outcomes are required to ensure that GRS-C implementation facilitates improved patient care.

RESUMEN

Background and Aims. A colonoscopy triage sheet (CTS) integrating 6 hierarchical scheduling priorities based on indications for screening, surveillance, or symptoms was designed for colonoscopy referral. We compared CTS priority ratings by referring physicians and endoscopists, assessing yields. Methods. Retrospective study of consecutive patients. Data were collected on demographics, CTS and endoscopist priority ratings, and endoscopic findings. Weighted kappa values measured interrater agreement on priority assignment. Predictors of agreement and lesions were identified using multivariable analysis. Results. Among 1230 patients (60.3 years, 52.5% female), clinically significant lesions included tumors (1.1%), polyps per patient ≥ 10 mm (7.6%), and ileocolitis (4.6%). Moderate agreement was found between referring physician and endoscopist on all 6 priorities (weighted kappa 0.55 (0.51; 0.59)). P4 and P5 ratings predicted increased agreement (range of OR for P4: 2.47-4.57; P5: 1.58-2.93). Predictors of clinically significant findings were male gender (OR 1.44, 1.03-2.03) and P1/P2 priorities that were significantly superior to P3 (OR = 2.14; 1.04-4.43), P4 (OR = 2.90; 1.35-6.23), and P5 (OR = 4.30; 2.08-8.88). Conclusion. Priority-assignment agreement is moderate and highest for less urgent ratings. Predictors of clinically significant findings validate the hierarchal priority scheme. Broader validation and physician education are needed.

RESUMEN

BACKGROUND: Mortality rates greater than in the general population have been reported in the population with Crohn's disease (CD), but reports for ulcerative colitis (UC) are conflicting. Trends with time were rarely described. We aimed to assess whether CD and UC mortality in Québec differs from that in the general population and to describe the trends over a 10-year observation period. METHODS: This is a population-based cohort study using the Québec administrative health databases and death certificates registry. All-cause and cause-specific standardized mortality ratios (SMRs) were computed for 1999 to 2008. A time trend analysis was used to assess changes in the SMR with the calendar year. RESULTS: All-cause mortality was significantly increased in CD and UC compared to the general population: SMR: CD 1.45 (95% confidence interval: 1.34-1.58), UC 1.21 (95% confidence interval: 1.12-1.32). In CD, mortality from digestive conditions, all neoplasms, digestive neoplasms, and colorectal, lymphatic, and lung cancer was significantly higher than in the general population. In UC, mortality from digestive, respiratory, and infectious conditions was also significantly increased. In both CD and UC, there was a decrease with time in all-cause SMRs and in digestive conditions, digestive neoplasms, colorectal cancer, and infectious diseases. SMRs for lung cancer and respiratory conditions increased over time in CD. CONCLUSIONS: All-cause mortality was significantly higher in CD and UC populations than in the general population. However, a decreasing trend with time was observed in all-cause and some cause-specific SMRs. In CD, SMRs for lung cancer and respiratory conditions increased during the observation period.

RESUMEN

BACKGROUND: Operator fatigue may negatively influence adenoma detection (AD) during screening colonoscopy. OBJECTIVE: To better characterize factors affecting AD, including the number of hours worked, and the number and type of procedures performed before an index screening colonoscopy. METHODS: A retrospective cohort study was conducted involving individuals undergoing a screening colonoscopy at a major tertiary care hospital in Montreal, Quebec. Individuals were identified using an endoscopic reporting database; AD was identified by an electronic chart review. A hierarchical logistic regression analysis was performed to determine the association between patient- and endoscopist-related variables and AD. RESULTS: A total of 430 consecutive colonoscopies performed by 10 gastroenterologists and two surgeons were included. Patient mean (± SD) age was 63.4±10.9 years, 56.3% were males, 27.7% had undergone a previous colonoscopy and the cecal intubation rate was 95.7%. The overall AD rate was 25.7%. Age was associated with AD (OR 1.06 [95% CI 1.03 to 1.08]), while female sex (OR 0.44 [95% CI 0.25 to 0.75]), an indication for average-risk screening (OR 0.47 [95% CI 0.27 to 0.80]) and an increase in the number of hours during which endoscopies were performed before the index colonoscopy (OR 0.87 [95% CI 0.76 to 0.99]) were associated with lower AD rates. On exploratory univariable analysis, a threshold of 3 h of endoscopy time performed before the index colonoscopy was associated with decreased AD. CONCLUSION: The number of hours devoted to endoscopies before the index colonoscopy was inversely associated with AD rate, with decreased performance possibly as early as within 3 h. This metric should be confirmed in future studies and considered when optimizing scheduling practices.
