Index admission cholecystectomy for biliary acute pancreatitis or choledocholithiasis reduces 30-day readmission rates in children.

BACKGROUND: Adult patients with biliary acute pancreatitis (BAP) or choledocholithiasis who do not undergo cholecystectomy on index admission have worse outcomes. Given the paucity of data on the impact of cholecystectomy during index hospitalization in children, we examined readmission rates among pediatric patients with BAP or choledocholithiasis who underwent index cholecystectomy versus those who did not. METHODS: Retrospective study of children (< 18 years old) admitted with BAP, without infection or necrosis (ICD-10 K85.10), or choledocholithiasis (K80.3x-K80.7x) using the 2018 National Readmission Database (NRD). Exclusion criteria were necrotizing pancreatitis with or without infected necrosis and death during index admission. Multivariable logistic regression was performed to identify factors associated with 30-day readmission. RESULTS: In 2018, 1122 children were admitted for index BAP (n = 377, 33.6%) or choledocholithiasis (n = 745, 66.4%). Mean age at admission was 13 (SD 4.2) years; most patients were female (n = 792, 70.6%). Index cholecystectomy was performed in 663 (59.1%) of cases. Thirty-day readmission rate was 10.9% in patients who underwent cholecystectomy during that index admission and 48.8% in those who did not (p < 0.001). In multivariable analysis, patients who underwent index cholecystectomy had lower odds of 30-day readmission than those who did not (OR 0.16, 95% CI 0.11-0.24, p < 0.001). CONCLUSIONS: Index cholecystectomy was performed in only 59% of pediatric patients admitted with BAP or choledocholithiasis but was associated with 84% decreased odds of readmission within 30 days. Current guidelines should be updated to reflect these findings, and future studies should evaluate barriers to index cholecystectomy.

Index admission cholecystectomy for acute cholecystitis reduces 30-day readmission rates in pediatric patients.

BACKGROUND: Adult patients with cholecystitis who do not undergo cholecystectomy on index admission have worse outcomes, however, there is a paucity of data of the role of cholecystectomy during index hospitalization in the pediatric population. Our aim was to determine outcomes and readmission rates among pediatric patients with cholecystitis who underwent index cholecystectomy versus those who did not. METHODS: We performed a retrospective study of pediatric (< 18 years old) admitted with acute cholecystitis (AC) requiring hospitalization using the 2018 National Readmission Database (NRD). Exclusion criteria included age ≥ 18 years and death on index admission. Multivariable logistic regression was performed to identify factors associated with 30-day readmissions. RESULTS: We identified 550 unique index acute cholecystitis admissions. Mean age was 14.6 ± 3.0 years. Majority of patients were female (n = 372, 67.6%). Index cholecystectomy was performed in (n = 435, 79.1%) of cases. Thirty-day readmission rate was 2.8% in patients who underwent index cholecystectomy and 22.6% in those who did not (p < 0.001). On multivariable analysis, patients who did not undergo index cholecystectomy had higher odds of 30-day readmission than those who did not (OR 10.66, 95% CI 5.06-22.45, p < 0.001). Female patients also had higher odds of 30-day readmission compared to males (OR 3.37, 95% CI 1.31-8.69). CONCLUSIONS: Patients who did not undergo index cholecystectomy had over tenfold increase in odds of 30-day readmission. Further research is required to understand the barriers to index cholecystectomy despite society recommendations and clear clinical benefit.

Impact of Telemedicine on No-Show Rates in an Ambulatory Gastroenterology Practice.

Background: Studies suggest that telemedicine worsens health care disparities in certain groups, partly owing to a lack of access to appropriate technology or poor technological literacy. Our aim was to use clinic no-show data to determine the impact of telemedicine on patient access to care in the ambulatory gastroenterology setting. Methods: Single-center retrospective study of ambulatory in-person and telemedicine clinic appointments comparing the 15-month prepandemic (PP) with the first 15 months during the pandemic (DTP) using an administrative database. Statistical analysis was performed using univariate and multivariable logistic regression. Results: About 9,746 and 12,808 patient-encounters were scheduled PP and DTP respectively. The no-show rate decreased from 9.8% to 6.9% DTP (p < 0.001). The no-show rate decreased for Black (p = 0.02) and non-Hispanic White patients (p = 0.018). The no-show rate increased for LatinX (p < 0.001) and Asian (p = 0.007) patients. In multivariate analysis, older patients and patients identifying as Black, Asian, or LatinX all had higher odds of no-show DTP (p < 0.05 for all). Patients from high-income counties were 43% less likely to no-show than those in the lowest income counties. Conclusions: The transition to telemedicine improves health care access by decreasing the overall no-show rate. Some groups have been negatively affected, including the older, lower income, LatinX, and Asian populations. Future studies should aim to identify the risk factors within these populations that can be modified to increase health care participation, including targeted application of in-person visits, and improved technology to drive engagement.

Telecytology versus in-room cytopathologist for EUS-guided FNA or fine-needle biopsy sampling of solid pancreatic lesions.

BACKGROUND AND AIMS: Rapid on-site-evaluation (ROSE) with an in-room cytopathologist (ROSE-P) has been shown to improve the diagnostic yield of specimens obtained from patients undergoing EUS-guided FNA or fine-needle biopsy sampling (EUS-FNAB) of pancreatic lesions. Recently, there has been an increased interest and use of ROSE using telecytology (ROSE-T) to optimize clinical workflows and to address social distancing mandates created during the coronavirus disease 2019 pandemic. The purpose of this study was to compare diagnostic outcomes of ROSE-P and ROSE-T. METHODS: A single-center cohort study of patients who underwent EUS-FNAB of solid pancreatic lesions with ROSE was conducted. The primary outcome was overall diagnostic yield of cancer. All patients who underwent EUS-FNAB were entered into a prospectively maintained database. Statistical analyses were performed using descriptive statistics and univariate analysis. RESULTS: There were 165 patients in each arm. There was no difference in diagnostic yield between ROSE-P and ROSE-T (96.4% vs 94.5%, P = .428). ROSE-T was associated with an increased use of 22-gauge needles (P = .006) and more needle passes (P < .001). No significant differences were found in age, gender, lesion size, needle type, procedure times, or adverse events between the 2 groups (P < .05 for all). More pancreatic tail lesions were sampled in the ROSE-P group (P < .001). CONCLUSIONS: ROSE-T was not associated with any difference in final histologic diagnosis for EUS-FNAB of solid pancreatic masses. This has important implications for optimizing clinical workflows.

Over-the-Scope Clips Versus Standard Endoscopic Treatment for First Line Therapy of Non-variceal Upper Gastrointestinal Bleeding: Systematic Review and Meta-Analysis.

BACKGROUND AND AIMS: Over-The-Scope Clips (OTSC) use have shown promising results for first line treatment of non-variceal upper gastrointestinal bleeding (NVUGIB). We conducted this meta-analysis to compare outcomes in patients treated with OTSC versus standard endoscopic intervention for first line endoscopic treatment of NVUGIB. METHODS: We reviewed several databases from inception to December 9, 2022 to identify studies comparing OTSC and standard treatments as the first line treatment for NVUGIB. The outcomes assessed included re-bleeding, initial hemostasis, need for vascular embolization, mortality, need for repeat endoscopy, 30 day readmission rate, and need for surgery. Pooled risk ratios (RR) with 95% confidence intervals (CI) were calculated using random effect model. Heterogeneity was assessed by I2 statistic. RESULTS: We included 11 studies with 1608 patients (494 patients in OTSC group and 1114 patients in control group). OTSC use was associated with significantly lower risk of re-bleeding (RR, 0.58; 95% CI 0.41-0.82). We found no significant difference in rates of initial hemostasis (RR, 1.05; 95% CI 0.99- 1.11), vascular embolization rates (RR, 0.93; 95% CI 0.40- 2.13), need for repeat endoscopy (RR, 0.78; 95% CI 0.40-1.49), 30 day readmission rate (RR, 0.59; 95% CI 0.17-2.01), need for surgery (RR, 0.81; 95% CI 0.29-2.28) and morality (RR, 0.69; 95% CI 0.38-1.23). CONCLUSIONS: OTSC are associated with significantly lower risk of re-bleeding compared to standard endoscopic treatments when used as first line endoscopic therapy for NVUGIB.

Practice patterns of post-ERCP pancreatitis prophylaxis techniques in the United States: a survey of advanced endoscopists.

BACKGROUND AND AIMS: The American Society for Gastrointestinal Endoscopy recommends prophylactic pancreatic duct stent placement (PPS) and rectal nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce the incidence and severity of post-ERCP pancreatitis (PEP) in high-risk individuals and suggests that rectal indomethacin may decrease the risk and severity of PEP in average-risk individuals. The European Society for Gastrointestinal Endoscopy recommends rectal indomethacin for all patients undergoing ERCP. Previous surveys of European endoscopists revealed low adoption of PPS or rectal NSAIDs to prevent PEP. We sought to capture current practice in the prevention of PEP among endoscopists in the United States involved in advanced endoscopy fellowship programs. METHODS: An anonymous online 16-item survey was e-mailed to 233 advanced endoscopists involved in advanced endoscopy fellowship programs. RESULTS: Of the 233 endoscopists who were invited to participate, 62 responded (26.7%). Most respondents reported working in tertiary referral centers (57; 95.0%) and performing ERCP for greater than 5 years (44; 74.6%). All respondents (60; 100.0%) reported working with fellows. Most PPS users (41; 72.0%) reported use of PPS in high-risk patients only and using PPS for PEP in ≤25% of ERCPs (38; 64.4%). Most respondents reported using rectal NSAIDs for high-risk patients only (34; 59.7%) compared with respondents (23; 40.1%) who reported using rectal NSAIDs for prevention of PEP in average-risk patients undergoing ERCP. Most respondents (49; 83.0%) also reported using rapid intravenous fluids to prevent PEP. CONCLUSIONS: Among endoscopists involved in advanced endoscopy fellowships in the United States, rectal NSAIDs are used more frequently than PPS in the prevention of PEP. Despite mounting evidence supporting the use of rectal NSAIDs to prevent PEP in average-risk patients, less than half of the respondents in this survey reported such practice.

Safety of Flexible Sigmoidoscopy in Pregnant Patients with Known or Suspected Inflammatory Bowel Disease.

BACKGROUND AND AIMS: Lower gastrointestinal endoscopy is crucial in the diagnosis and staging of inflammatory bowel disease (IBD). However, there are limited safety data in pregnant populations, resulting in conservative society guidelines and practice patterns favoring diagnostic delay. We studied whether performance of flexible sigmoidoscopy is associated with adverse events in pregnant patients with known or suspected IBD. METHODS: A retrospective cohort study was conducted at the University of California San Francisco (UCSF) between April 2008 and April 2019. Female patients aged between 18 and 48 years who were pregnant at the time of endoscopy were identified. All patient records were reviewed to determine disease, pregnancy outcomes, and lifestyle factors. Two independent reviewers performed the data abstraction. Adverse events were assessed for temporal relation with endoscopy. RESULTS: We report the outcomes of 48 pregnant patients across all trimesters who underwent lower endoscopy for suspected or established IBD. There were no hospitalizations or adverse obstetric events temporally associated with sigmoidoscopy. 78% (38/50) of lower endoscopies performed in the patients resulted in a change in treatment following sigmoidoscopy. 12% (5/43) of the lower endoscopies performed in patients with known IBD showed no endoscopic evidence of disease activity despite symptoms. CONCLUSIONS: Lower endoscopy in the pregnant patient with known or suspected IBD is low risk and affects therapeutic decision making. It should not be delayed in patients with appropriate indications.

Population health interventions to improve colorectal cancer screening by fecal immunochemical tests: A systematic review.

Despite clear evidence that colorectal cancer (CRC) screening reduces mortality, screening, including fecal immunochemical tests (FIT), is underutilized. We conducted a systematic review to determine the evidence of efficacy of interventions to improve FIT completion that could be scaled and utilized in population health management. We systematically searched publication databases for studies evaluating provider- or system-level interventions to improve CRC screening by FIT between 1 January 1996 and 13 December 2017 without language restrictions. Twenty articles describing 25 studies were included, 23 were randomized controlled trials with 1 quasi-experimental and 1 observational study. Ten studies discussed mailed FIT outreach, 4 pre-FIT patient reminders, 3 tailored patient messages, 2 post-FIT reminders, 2 paired FIT with influenza vaccinations, 2 provider alerts and 1 study each described the use of high-quality small media and patient financial incentives. Mailed FIT outreach was consistently effective with median improvement in CRC screening of 21.5% (interquartile range (IQR) 13.6%-29.0%). FIT paired with vaccinations led to a median 15.9% (IQR 15.6%-16.3%) improvement, while pre-FIT and post-FIT reminders demonstrated modest efficacy with median 4.1% (IQR 3.6%-6.7%) and 3.1% (IQR 2.9%-3.3%) improvement in CRC screening, respectively. More than half the studies were at high or unclear risk of bias; heterogeneous study designs and characteristics precluded meta-analysis. FIT-based CRC screening programs utilizing multilevel interventions (e.g. mailed FIT outreach, FIT paired with other preventative services, and provider alerts) have the potential to significantly increase screening participation. However, such programs must also follow-up patients with abnormal FIT results.

Impact of Insurance Status and Race on Outcomes in Nonvariceal Upper Gastrointestinal Hemorrhage: A Nationwide Analysis.

BACKGROUND AND GOALS: We examined the interaction between race, insurance, and important outcomes in nonvariceal upper gastrointestinal hemorrhage (NVUGIH). STUDY: Adults with NVUGIH were selected from the National Inpatient Sample. PRIMARY OUTCOME: in-hospital mortality. SECONDARY OUTCOMES: treatment modalities [esophagogastroduodenoscopy (EGD), early EGD, and endoscopic or radiologic therapy], and resource utilization (length of hospital stay and total hospitalization charges). RESULTS: Mortality was similar for Medicare and private insurance [adjusted odds ratios (aOR): 1.15 95% confidence interval (CI) 0.90 to 1.47), P=0.24], but higher for under/uninsured patients [aOR: 1.84 (CI: 1.42 to 2.40), P<0.01]. Compared with Medicare, patients with private insurance had more EGDs [aOR: 1.35 (CI: 1.23 to 1.48), P<0.01], early EGDs [aOR: 1.29 (CI: 1.21 to 1.38), P<0.01], and endoscopic [aOR: 1.19 (CI: 1.11 to 1.27), P<0.01], or radiologic therapy [aOR:1.35 (CI: 1.06 to 1.71), P=0.01]. Patients who were under/uninsured had less EGDs [aOR: 0.84 (CI: 0.76 to 0.91), P<0.01] or endoscopic therapy [aOR: 0.74 (CI: 0.68 to 0.81), P<0.01], but similar odds of early EGD [aOR: 0.95 (CI: 0.88 to 1.02), P=0.13] or radiologic therapy [aOR: 1.01 (CI: 0.75 to 1.37), P=0.75]. Compared with whites, blacks had lower [aOR: 0.73 (CI: 0.58 to 0.93), P=0.01] and Native Americans higher mortality [aOR: 2.60 (CI: 1.57 to 4.13), P<0.01]. Blacks were less likely [aOR: 0.86 (CI: 0.79 to 0.94), P<0.01] and Asians more likely [aOR: 1.24 (CI: 1.05 to 1.47), P=0.01] to have EGDs. Both blacks and Hispanics had lower, whereas Asians had higher early EGD rates. Patients with private insurance had lower total charges [adjusted mean difference: -$2761 (CI: -$4617 to -$906), P<0.01]. CONCLUSIONS: Insurance and race have independent effects on NVUGIH mortality, therapeutic modalities used, and resource utilization. Black and under/uninsured patients have the worst outcomes.

Current state of biliary cannulation techniques during endoscopic retrograde cholangiopancreatography (ERCP): International survey study.

Background and study aims Endoscopist techniques affect biliary cannulation success and the risk of adverse events during endoscopic retrograde cholangiopancreatography (ERCP). This survey study aims to understand the current practice of biliary cannulation techniques among endoscopists. Methods Practicing endoscopists were sent an anonymous 28-question electronic survey on biliary cannulation techniques and intraprocedural pancreatitis prophylactic strategies. Results The survey was completed by 692 endoscopists (6.2% females). A wire-guided cannulation technique (WGT) was the preferred initial biliary cannulation approach (95%). The preferred secondary approaches were a double-wire (DWT) (65.8%), precut needle-knife technique (NKT) (25.7%), transpancreatic sphincterotomy (5.9%) or other (2.6%). Overall, 18.1% of respondents were not comfortable with NKTs. In the setting of pancreatic duct (PD) access, 81.9% and 97% reported a threshold of three or more wire passes or contrast injections into the PD, respectively, before changing strategy, 34% reported placement of a prophylactic PD stent <50% of the time and 12.1% reported removal of the PD stent at the end of the procedure. Advanced endoscopy fellowship (AEF) training and high volume (>200 ERCPs per year) were associated with comfort with precut NKTs and likelihood of prophylactic PD stent ( P <0.001 for both). Conclusions A WGT technique followed by the DWT and NKT were the preferred biliary cannulation techniques; however, almost one-fifth of respondents were not comfortable with the NKT. There was considerable variability in secondary cannulation approaches, time spent attempting biliary cannulation and prophylactic PD stent placement, factors known to be associated with cannulation success and adverse outcomes.

United States aid policy and induced abortion in sub-Saharan Africa.

OBJECTIVE: To determine whether the Mexico City Policy, a United States government policy that prohibits funding to nongovernmental organizations performing or promoting abortion, was associated with the induced abortion rate in sub-Saharan Africa. METHODS: Women in 20 African countries who had induced abortions between 1994 and 2008 were identified in Demographic and Health Surveys. A country's exposure to the Mexico City Policy was considered high (or low) if its per capita assistance from the United States for family planning and reproductive health was above (or below) the median among study countries before the policy's reinstatement in 2001. Using logistic regression and a difference-in-difference design, the authors estimated the differential change in the odds of having an induced abortion among women in high exposure countries relative to low exposure countries when the policy was reinstated. FINDINGS: The study included 261,116 women aged 15 to 44 years. A comparison of 1994-2000 with 2001-2008 revealed an adjusted odds ratio for induced abortion of 2.55 for high-exposure countries versus low-exposure countries under the policy (95% confidence interval, CI: 1.76-3.71). There was a relative decline in the use of modern contraceptives in the high-exposure countries over the same time period. CONCLUSION: The induced abortion rate in sub-Saharan Africa rose in high-exposure countries relative to low-exposure countries when the Mexico City Policy was reintroduced. Reduced financial support for family planning may have led women to substitute abortion for contraception. Regardless of one's views about abortion, the findings may have important implications for public policies governing abortion.

Accuracy of medical billing data against the electronic health record in the measurement of colorectal cancer screening rates.

OBJECTIVE: Medical billing data are an attractive source of secondary analysis because of their ease of use and potential to answer population-health questions with statistical power. Although these datasets have known susceptibilities to biases, the degree to which they can distort the assessment of quality measures such as colorectal cancer screening rates are not widely appreciated, nor are their causes and possible solutions. METHODS: Using a billing code database derived from our institution's electronic health records, we estimated the colorectal cancer screening rate of average-risk patients aged 50-74 years seen in primary care or gastroenterology clinic in 2016-2017. 200 records (150 unscreened, 50 screened) were sampled to quantify the accuracy against manual review. RESULTS: Out of 4611 patients, an analysis of billing data suggested a 61% screening rate, an estimate that matches the estimate by the Centers for Disease Control. Manual review revealed a positive predictive value of 96% (86%-100%), negative predictive value of 21% (15%-29%) and a corrected screening rate of 85% (81%-90%). Most false negatives occurred due to examinations performed outside the scope of the database-both within and outside of our institution-but 21% of false negatives fell within the database's scope. False positives occurred due to incomplete examinations and inadequate bowel preparation. Reasons for screening failure include ordered but incomplete examinations (48%), lack of or incorrect documentation by primary care (29%) including incorrect screening intervals (13%) and patients declining screening (13%). CONCLUSIONS: Billing databases are prone to substantial bias that may go undetected even in the presence of confirmatory external estimates. Caution is recommended when performing population-level inference from these data. We propose several solutions to improve the use of these data for the assessment of healthcare quality.

Soft tissue thermodynamics before, during, and after cold pack therapy.

BACKGROUND: Cold packs are commonly used by clinicians, trainers, and others, often as an interim treatment for many acute conditions, but the extent of temperature change associated with this form of treatment remains poorly understood. METHODS: In 16 healthy male and female volunteers aged 25.4 +/- 3.6 yr, we monitored skin temperature, and recorded the temperature of the quadriceps muscle at 1, 2, and 3 cm depths below the skin, before, during, and after 20 min of cold pack treatment. RESULTS: The results revealed a slight rise in temperature at all four levels during the 5 min pretreatment period, but significant temperature falls at the skin and 1 cm levels beginning from 8 min of treatment (P < 0.001). There was no significant change in tissue temperature at the 2.0 cm or 3.0 cm depths throughout treatment. However, after treatment, cutaneous temperature and the temperature at 1.0 cm depth rose rapidly, returning to baseline levels at variable intersubject times. As these superficial temperatures rose, there were concurrent falls in the temperatures at the 2.0 cm and 3.0 cm levels. Thus, the deeper tissues lost heat (cooled) simultaneously as the superficial tissues rewarmed; to the extent that 40 min after treatment, the deeper levels were cooler than the cutaneous and 1.0 cm levels. CONCLUSION: 1) Cold pack therapy produces significant temperature falls in cutaneous and subcutaneous superficial tissues without directly changing the temperature of tissues at or more than 2.0 cm below the skin; and 2) the temperature gradients of both layers of tissue reverses after treatment, indicating that the deep tissue beneath is at least one of the sources of heat used to rewarm the cooled superficial tissue. The latter finding underscores the importance of the hemodynamic interchange between superficial and deep tissues, and offers an explanation for the reduction of pain, muscle spasm, and edema observed with cold therapy in several clinical situations.
