RESUMO
BACKGROUND AND AIMS: Informed consent should allow patients the appropriate time and conditions to make decisions about their care. However, consent is often obtained immediately prior to a colonoscopy. We conducted a quality improvement study to assess how a preprocedure consent video 2 days prior to an outpatient colonoscopy impacts patient satisfaction. METHODS: Patients undergoing outpatient colonoscopy at a large academic medical center opted in to a text messaging platform for procedural information. Our intervention was an informed consent video 2 days before the colonoscopy. Our primary outcome was a composite patient satisfaction score. Pre and postintervention scores were compared using ordinal or multinomial logistic models to calculate odds ratios (OR) or relative risk ratios and 95% confidence intervals (CI), adjusting for age and sex. RESULTS: 1109 and 1452 patients completed ≥1 survey question in the pre and postintervention phases, respectively. Overall patient satisfaction did not differ between groups [OR for a 1-point increment in satisfaction score between post- vs pre-intervention groups = 1.05; 95% CI: 0.90-1.22; P = .51]. Compared to preintervention, postintervention respondents were more likely to report higher satisfaction with time available to talk with their physician (OR of a 1-point increase in individual question response = 1.29; 95% CI: 1.09-1.54; P = .004). Compared to preintervention, more physicians in the postintervention phase rated satisfaction with consent process efficiency as "very satisfied" or "satisfied" (P < .001). CONCLUSION: An informed consent video prior to colonoscopy resulted in similar overall patient satisfaction. However, post-intervention, patients were more likely to report sufficient time to talk with their physician, and physicians reported higher satisfaction with consent efficiency.
RESUMO
Thousands of colonoscopies were canceled during the initial surge of the COVID-19 pandemic. As facilities resumed services, some patients were hesitant to reschedule. The purpose of this study was to determine whether a decision aid plus telephone coaching would increase colorectal cancer (CRC) screening and improve patient reports of shared decision making (SDM). A randomized controlled trial assigned adults aged 45-75 without prior history of CRC who had a colonoscopy canceled from March to May 2020 to intervention (n = 400) or usual care control (n = 400) arms. The intervention arm received three-page decision aid and call from decision coach from September 2020 through November 2020. Screening rates were collected at 6 months. A subset (n = 250) in each arm was surveyed 8 weeks after randomization to assess SDM (scores range 0-4, higher scores indicating more SDM), decisional conflict, and screening preference. The sample was on average, 60 years old, 53% female, 74% White, non-Hispanic, and 11% Spanish speaking. More intervention arm patients were screened within 6 months (35% intervention vs 23% control, p < 0.001). The intervention respondents reported higher SDM scores (mean difference 0.7 [0.4, 0.9], p < 0.001) and less decisional conflict than controls (-21% [-35%, -7%], p = 0.003). The majority in both arms preferred screening versus delaying (68% intervention vs. 65% control, p = 0.75). An SDM approach that offered alternatives and incorporated patients' preferences resulted in higher screening rates. Patients who are overdue for CRC screening may benefit from proactive outreach with SDM support.

Background. Early in the COVID-19 pandemic colonoscopies for colorectal cancer (CRC) screening were canceled. Patient perceptions of the benefits and risks of routine screening relative to health concerns associated with the COVID-19 pandemic were unknown. Purpose. Assess patient anxiety, worry, and interest in CRC screening during the COVID-19 pandemic. Methods. A random sample of 200 patients aged 45 to 75 y with colonoscopy cancellation due to COVID-19 in March to May 2020 were surveyed. Anxiety, COVID-19 and CRC risk perceptions, COVID-19 and CRC worry, likelihood of following through with colonoscopy in the next month, and interest in alternatives to colonoscopy were assessed. Subsequent screening was tracked for 12 mo. Results. Respondents (N = 127/200, 63.5%) were on average 60 y old, female (59%), college educated (62% college degree or more), and White (91%). A substantial portion of patients (46%) stated they may not follow through with a colonoscopy in the next month. There was greater interest in stool-based testing than in delaying screening (48% v. 26%). Women, older patients, and patients indicating tolerance of uncertainty due to complexity reported they were less likely to follow through with colonoscopy in the next month. Greater interest in stool-based testing was related to lower perceptions of CRC risk. Greater interest in delaying screening was related to less worry about CRC and less tolerance of risk. Over 12 mo, 60% of participants completed screening. Patients who stated they were more likely to screen in the next month were more likely to complete CRC screening (P = 0.01). Conclusions. Respondents who had a colonoscopy canceled during the COVID-19 pandemic varied in interest in rescheduling the procedure. A shared decision-making approach may help patients address varying concerns and select the best approach to screening for them. Highlights: In the wake of the first wave of the COVID-19 pandemic, almost half of patients stated they were not likely to follow through with a colonoscopy in the short term, about half were interested in screening with a stool-based test, and only one-quarter were interested in delaying screening until next year.Patients who perceived themselves at higher risk of colorectal cancer were less interested in stool-based testing, and patients who were more worried about colorectal cancer were less interested in delaying screening.A shared decision-making approach may be necessary to tailor screening discussions for patients during subsequent waves of the pandemic, other occasions where resources are limited and patient preferences vary, or where patients hold conflicting views of screening.
RESUMO
INTRODUCTION: Continuous left ventricular assist devices (LVADs) offer hemodynamic support in advanced and decompensated heart failure but are often complicated by gastrointestinal bleeding (GIB) in medically fragile patients. METHODS: We performed a retrospective analysis of 475 consecutive patients who underwent LVAD implantation at the Massachusetts General Hospital and Tufts Medical Center from 2008 to 2019 and identified 128 patients with clinically significant GIB. Clinical characteristics of each bleeding event, including procedures and interventions, were recorded. We examined LVAD patients with overt and occult presentations to determine diagnostic endoscopic yield and analyzed predictors of recurrent GIB. RESULTS: We identified 128 unique patients with LVAD implantation complicated by GIB. No significant difference was observed based on study center, underlying cardiomyopathy, race/ethnicity, serum indices, and medications used. Overt bleeders presented more commonly during LVAD implantation admission ( P = 0.001) than occult bleeders. Occult bleed presentations had only 1 lower and no middle GI bleed source identified, despite similar workups to overt bleeds. Destination therapy (e.g., among nontransplant candidates) LVAD implantation (odds ratio 2.38, 95% confidence interval 1.05-5.58) and a history of GIB (odds ratio 3.85, 95% confidence interval 1.29-12.7) were independently associated with an increased risk of recurrent GIB-related hospitalization. DISCUSSION: Our findings confirm a high rate of GIB, especially in destination LVAD patients, and show a low diagnostic yield for colonoscopy and middle GI bleed assessments in LVAD patients with occult bleeds. Overt bleeding was more common and associated with vascular malformations. Although endoscopic interventions stopped active hemorrhage, GIB often recurred.

INTRODUCTION: Low colorectal cancer (CRC) screening rates among Hispanic and Latino patients result in advanced disease at the time of diagnosis and decreased survival chances. METHODS: We performed a prospective study at an academic endoscopy center in Boston, Massachusetts from May 1, 2019 to January 31, 2020. We identified 887 Spanishspeaking patients as controls and enrolled 412 (59%) Spanish-speaking patients in a short message service (SMS) program for pre-procedure instructions. RESULTS: Intervention and control group participants were similar in age, sex, and indications. Patients receiving SMS messages were less likely to no-show or cancel last minute (OR=1.66, 95%CI=0.44-0.83, p=.002) and had more adequate bowel preparations compared with the control arm (OR=1.55, 95%CI=0.45-0.92, p=.01). Overall, 93% (117/126) of patients stated they would "highly recommend" the program to others. CONCLUSIONS: Our automated SMS reminders for colonoscopy preparation increased appointment adherence, bowel preparation quality, and showed good patient satisfaction among Spanish speakers.

INTRODUCTION: Delays in inpatient colonoscopy are commonly caused by inadequate bowel preparation and result in increased hospital length of stay (LOS) and healthcare costs. Low-volume bowel preparation (LV-BP; sodium sulfate, potassium sulfate, and magnesium sulfate ) has been shown to improve outpatient bowel preparation quality compared with standard high-volume bowel preparations (HV-BP; polyethylene glycol ). However, its efficacy in hospitalized patients has not been well-studied. We assessed the impact of LV-BP on time to colonoscopy, hospital LOS, and bowel preparation quality among inpatients. METHODS: We performed a propensity score-matched analysis of adult inpatients undergoing colonoscopy who received either LV-BP or HV-BP before colonoscopy at a quaternary academic medical center. Multivariate regression models with feature selection were developed to assess the association between LV-BP and study outcomes. RESULTS: Among 1,807 inpatients included in this study, 293 and 1,514 patients received LV-BP and HV-BP, respectively. Among the propensity score-matched population, LV-BP was associated with a shorter time to colonoscopy (ß: -0.43 [95% confidence interval: -0.56 to -0.30]) while having similar odds of adequate preparation (odds ratio: 1.02 [95% confidence interval: 0.71-1.46]; P = 0.92). LV-BP was also significantly associated with decreased hospital LOS among older patients (age ≥ 75 years), patients with chronic kidney disease, and patients who were hospitalized with gastrointestinal bleeding. DISCUSSION: LV-BP is associated with decreased time to colonoscopy in hospitalized patients. Older inpatients, inpatients with chronic kidney disease, and inpatients with gastrointestinal bleeding may particularly benefit from LV-BP. Prospective studies are needed to further establish the role of LV-BP for inpatient colonoscopies.

INTRODUCTION: We evaluated factors that can predict the adequacy of bowel preparation in patients with chronic constipation undergoing colonoscopy. MATERIALS AND METHODS: We identified patients with chronic constipation who underwent anorectal manometry and at least 1 colonoscopy at 2 tertiary referral centers from 2003 to 2019. We also identified a subgroup of patients who underwent colonic transit testing through radiopaque marker testing. We determined demographic, medical, and constipation-related factors associated with poor bowel preparation and their effect on standardized quality metrics using univariate and multivariate analyses. RESULTS: We identified 274 patients with chronic constipation who underwent anorectal manometry testing. Both outlet dysfunction (prolonged balloon expulsion) and slow-transit constipation were associated with suboptimal bowel preparation. Outlet dysfunction was also associated with decreased cecal intubation rates, adenoma detection rates, and sessile serrated polyp detection rates. In multivariable analyses controlling for demographics and known factors associated with poor bowel preparation, outlet dysfunction was associated with an almost 3-fold odds of suboptimal bowel preparation [odds ratio (OR): 2.9; 95% confidence interval (CI): 1.6-5.1] and a 3-fold reduction in cecal intubation rates (OR: 0.3; 95% CI: 0.1-0.8). Among those with radiopaque marker colonic transit testing available, slow-transit constipation was associated with a >2-fold odds of suboptimal bowel preparation (OR: 2.2; 95% CI: 1.1-4.4). CONCLUSIONS: Among a cohort of patients with chronic constipation undergoing colonoscopy, outlet dysfunction was associated with suboptimal bowel preparation and other quality metrics. Constipated patients with a rectal evacuation disorder may represent a subgroup of patients that could benefit from individualized strategies for better bowel preparation.

BACKGROUND: Patients with cirrhosis and ascites experience frequent hospital admissions, leading to poor quality of life and high healthcare costs. Monitoring weight is a component of ascites care and telemonitoring may improve outcomes and costs. Goals We aimed to evaluate the cost and outcomes of current care compared to a telemonitoring system for ascites. Study We developed a decision-analytic model that examined 100 simulated patients over a 6-month horizon. We compared usual care to a new telemonitoring program, which we estimate costs $50,000/6 months. RESULTS: The cost of standard of care for 100 patients with cirrhotic ascites over a 6-month period is $167,500 more expensive than telemonitoring. By varying parameter probabilities by ± 10% and outcome costs by ± 20%, we found that standard of care remains more expensive than care with a telemonitoring intervention by $9400 to $340,200 per 6-month period. Standard of care leads to 9 more admissions (range 4 to 12) than a telemonitoring intervention, while telemonitoring leads to 9 more outpatient visits (range 6 to 9) and 28 additional outpatient large volume paracenteses (LVPs) (range 17 to 28). With more and less expensive telemonitoring interventions, standard of care remained more expensive. With 50% adherence to the intervention, standard of care was $89,848 more expensive. CONCLUSIONS: In almost all probability and cost scenarios, a telemonitoring intervention is cost-saving for the management of cirrhotic ascites. Using hospital admissions as a surrogate for quality of care, patient outcomes are improved primarily though more proactive medical intervention and more LVPs.

BACKGROUND AND AIMS: Performing colonoscopy can be technically challenging in female patients. Female patients may prefer having a female endoscopist. This preference, coupled with the fact that there are fewer female endoscopists, may result in gender differences in colonoscopy practice. We hypothesized that the duration of female colonoscopy is longer and that female endoscopists perform a higher proportion of female colonoscopy than male colleagues. We explored the potential revenue implications of gender differences in screening colonoscopy. METHODS: We analyzed procedure time and gender differences in 16,573 screening colonoscopies performed by 27 male and 7 female endoscopists over a three-year period in one large academic practice. We modeled the potential revenue impacts of differences in procedure duration, proportion of female colonoscopy and the frequency of detected adenomas. RESULTS: We found that screening colonoscopy takes 8.8% more time to complete in female patients compared to male patients for all endoscopists (p < 0.001), and that female endoscopists perform an average of 71.2% female exams compared to male endoscopists, who perform an average of 50.8% female exams (p < 0.001). Female patients had a lower detection adenoma rate (ADR), reducing the frequency of polypectomy and reimbursement in an RVU model. The observed gender differences could account for an estimated 9.6% revenue loss per 8-h session for a female gastroenterologist performing screening colonoscopy compared to a male counterpart. CONCLUSION: Longer colonoscopy duration in females, increased proportion of female colonoscopies for female endoscopists and lower ADR in females may contribute to the gender gap in physician pay in gastroenterology.

Presently, there is no agreed upon data-driven approach for identifying the geographic boundaries of migration networks that international migration systems are ultimately manifested in. Drawing from research on community detection methods, we introduce and apply the Information Theoretic Community Detection Algorithm for identifying and studying the geographic boundaries of migration networks. Using a new set of estimates of country-to-country migration flows every 5 years from 1990 to 1995 to 2010-2015, we trace the form and evolution of international migration networks over the past 25 years. Consistent with the concept of dynamic stability, we show that the number, size and internal country compositions of international migration networks have been remarkably stable over time; however, we also document many short-term fluctuations. We conclude by reflecting on the spirit of our work in this paper, which is to promote consensus around tools and best practices for identifying and studying international migration networks.
RESUMO
BACKGROUND: Ascites is a common, painful, and serious complication of cirrhosis. Body weight is a reliable proxy for ascites volume; therefore, daily weight monitoring is recommended to optimize ascites management. OBJECTIVE: This study aims to evaluate the feasibility of a smartphone app in facilitating outpatient ascites management. METHODS: In this feasibility study, patients with cirrhotic ascites requiring active management were identified in both inpatient and outpatient settings. Patients were provided with a Bluetooth-connected scale, which transmitted weight data to a smartphone app and then via the internet to an electronic medical record (EMR). Weights were monitored every weekday. In the event of a weight change of ≥5 lbs in 1 week, patients were called and administered a short symptom questionnaire, and providers received an email alert. The primary outcomes of this study were the percentage of enrolled days during which weight data were successfully transmitted to an EMR and the percentage of weight alerts that prompted responses by the provider. RESULTS: In this study, 25 patients were enrolled: 12 (48%) were male, and the mean age was 58 (SD 13; range 35-81) years. A total of 18 (72%) inpatients were enrolled. Weight data were successfully transmitted to an EMR during 71.2% (697/979) of the study enrollment days, with technology issues reported on 16.5% (162/979) of the days. Of a total of 79 weight change alerts fired, 41 (52%) were triggered by weight loss and 38 (48%) were by weight gain. Providers responded in some fashion to 66 (84%) of the weight alerts and intervened in response to 45 (57%) of the alerts, for example, by contacting the patient, scheduling clinic or paracentesis appointments, modifying the diuretic dose, or requesting a laboratory workup. Providers responded equally to weight increase and decrease alerts (P=.87). The staff called patients a mean of 3.7 (SD 3.5) times per patient, and the number of phone calls correlated with technology issues (r=0.60; P=.002). A total of 60% (15/25) of the patients chose to extend their participation beyond 30 days. A total of 17 patient readmissions occurred during the study period, with only 4 (24%) related to ascites. CONCLUSIONS: We demonstrated the feasibility of a smartphone app to facilitate the management of ascites and reported excellent rates of patient and provider engagement. This innovation could enable early therapeutic intervention, thereby decreasing the burden of morbidity and mortality among patients with cirrhosis.
RESUMO
Prior research on the "Great American Migration Slowdown," or the declining rate of U.S. internal migration in recent decades, is dominated by two research foci. The first is concerned with the determinants of the migration slowdown. The second is concerned with spatial heterogeneity in the migration slowdown in and across places. With respect to the aim of this paper, many studies of spatial heterogeneity in the migration slowdown have implicitly raised questions about whether and to what extent places are connected to one another by migration flows, or the spatial interconnectivity of migration. The spatial interconnectivity of migration is a concrete manifestation of underlying spatial interdependence among places, and, as such, deserves to be explicitly unpacked to further our understanding of the migration slowdown. Using county-to-county migration flow data from the Internal Revenue Service and a novel application of Das Gupta's demographic standardization and decomposition procedures, we document changes in the spatial interconnectivity of migration during the migration slowdown between 1990 and 2010. We show that counties became more connected to one another by migration over time, and that the increasing spatial interconnectivity of migration helped to keep the migration slowdown from slowing further. We also document changes in the spatial interconnectivity of migration for four types of migration flows: metro-to-metro, nonmetro-to-metro, metro-to-nonmetro, and nonmetro-to-nonmetro. Our work further elucidates the characteristics of the migration slowdown by describing changes in the spatial interconnectivity of migration. It also raises new questions for future research about the determinants and consequences of these changes.
RESUMO
Introduction:Many patients struggle with colonoscopy preparation, which is complex and can be an uncomfortable as well as a time-consuming process. The confusion and anxiety from the preprocedure process may lead patients to delay their colonoscopy or skip it altogether. Digital health technology that focuses on patient engagement can play an important role in promoting colorectal cancer screening.Methods:A digital preprocedure instruction program was implemented for outpatient colonoscopy by sending critical reminders and instructions to patients through a series of short message service messages and/or emails. Eligible patients included English speakers on GoLYTELY®/NuLYTELY® or MiraLAX® preparation regimens with a valid cellphone or email address in the electronic health record. We examined the impact of digital instructions on bowel preparation quality, no-show and same-day cancellations over a 3-month period between an intervention group of 756 patients and a control group of 2,103 patients. Patients who enrolled in the digital instructions also received a patient satisfaction survey.Results:Our controlled study demonstrated the effectiveness of digital instructions to reduce no-show and same-day cancellation rates for outpatient colonoscopy from 10.40% to 6.08% (p < 0.001). Bowel preparation quality was not significantly different between the two groups (p = 0.23). However, 90% of patients who enrolled in the program rated their satisfaction with the digital reminders very highly.Discussion:A digital preprocedure instruction program can have a positive impact on operational efficiency, quality of care, and patient satisfaction. This study shows how digital health tools can effectively engage patients scheduled for a colonoscopy, increase appointment adherence, and, therefore, lead to better cancer screening.

While important and timely, the recent effort to 'relaunch' migration systems as emergent entities is premised on a mischaracterization and subsequent dismissal of decades of research showing that systems are ultimately expressed in geographic structures in the form of migration networks comprised of a set of places that are connected to one another by migration flows. In this paper, we reconcile this relaunch with past research on migration systems by considering whether and how changes in some of the actors and dynamics that create and sustain migration systems are expressed in corresponding changes in the geographic structure of migration flows. By elucidating these linkages, our work helps to strengthen the aforementioned relaunch of migration systems by ensuring greater continuity with prior research and, going forward, the continued utility of a migration systems perspective for diverse audiences and issues.
RESUMO
Adverse climatic conditions may differentially drive human migration patterns between rural and urban areas, with implications for changes in population composition and density, access to infrastructure and resources, and the delivery of essential goods and services. However, there is little empirical evidence to support this notion. In this study, we investigate the relationship between climate shocks and migration between rural and urban areas within Mexico. We combine individual records from the 2000 and 2010 Mexican censuses (n=683,518) with high-resolution climate data from Terra Populus that are linked to census data at the municipality level (n=2,321). We measure climate shocks as monthly deviation from a 30-year (1961-1990) long-term climate normal period, and uncover important nonlinearities using quadratic and cubic specifications. Satellite-based measures of urban extents allow us to classify migrant-sending and migrant-receiving municipalities as rural or urban to examine four internal migration patterns: rural-urban, rural-rural, urban-urban, and urban-rural. Among our key findings, results from multilevel models reveal that each additional drought month increases the odds of rural-urban migration by 3.6%. In contrast, the relationship between heat months and rural-urban migration is nonlinear. After a threshold of ~34 heat months is surpassed, the relationship between heat months and rural-urban migration becomes positive and progressively increases in strength. Policy and programmatic interventions may therefore reduce climate induced rural-urban migration in Mexico through rural climate change adaptation initiatives, while also assisting rural migrants in finding employment and housing in urban areas to offset population impacts.
RESUMO
European Union (EU) enlargements in 2004 and 2007 were accompanied by increased migration from new-accession to established-member (EU-15) countries. The impacts of these flows depend, in part, on the amount of time that persons from the former countries live in the latter over the life course. In this paper, we develop period estimates of duration expectancy in EU-15 countries among persons from new-accession countries. Using a newly developed set of harmonised Bayesian estimates of migration flows each year from 2002 to 2008 from the Integrated Modelling of European Migration (IMEM) Project, we exploit period age patterns of country-to-country migration and mortality to summarize the average number of years that persons from new-accession countries could be expected to live in EU-15 countries over the life course. In general, the results show that the amount of time that persons from new-accession countries could be expected to live in the EU-15 nearly doubled after 2004.
