Decision Support and Behavioral Health for Reducing High-Dose Opioids in Comorbid Chronic Pain, Depression and Anxiety: Stepped-Wedge Cluster Randomized Trial.

BACKGROUND: High prevalence of depression or anxiety with opioid use for chronic pain complicates co-management and may influence prescribing behaviors. OBJECTIVE: Compare clinical effectiveness of electronic medical record clinical decision support (EMR-CDS) versus additional behavioral health (BH) care management for reducing rates of high-dose opioid prescriptions. DESIGN: Type 2 effectiveness-implementation hybrid stepped-wedge cluster randomized trial in 35 primary care clinics within a health system in LA, USA. PARTICIPANTS: Patients aged 18+ receiving chronic opioid therapy for non-cancer pain with depression or anxiety and matched controls. INTERVENTION: EMR-CDS included opioid risk mitigation procedures. BH care included cognitive behavioral therapy; depression or anxiety medication adjustments; and case management. MAIN MEASURES: Outcomes of interest included difference-in-difference (DID) estimate of changes in probability for prescribing high-dose morphine equivalent daily dose (MEDD ≥50 mg/day and MEDD ≥90), average MEDD, and rates of hospitalization, emergency department use, and opioid risk mitigation. KEY RESULTS: Most participants were female with 3+ pain syndromes. Data analysis included 632 patients. Absolute risk differences for MEDD≥50 and ≥90 decreased post-index compared to pre-index (DID of absolute risk difference [95%CI]: -0.036 [-0.089, 0.016] and -0.029 [-0.060, 0.002], respectively). However, these differences were not statistically significant. The average MEDD decreased at a higher rate for the BH group compared to EMR-CDS only (DID rate ratio [95%CI]: 0.85 [0.77, 0.93]). There were no changes in hospitalization and emergency department utilization. The BH group had higher probabilities of new specialty referrals and prescriptions for naloxone and antidepressants. CONCLUSIONS: Incorporation of a multidisciplinary behavioral health care team into primary care did not decrease high-dose prescribing; however, it improved adherence to clinical guideline recommendations for managing chronic opioid therapy for non-cancer pain.

Use of a New Standardized Unfractionated Heparin Protocol for Left-Sided Ablation Procedures Improves Time in the Therapeutic ACT Range.

OBJECTIVES: This study evaluated whether a novel standardized heparin dosing protocol used during atrial fibrillation catheter ablation resulted in a higher percentage of therapeutic activated clotting time (ACT) values compared to historic nonstandardized procedures. DESIGN: A retrospective cohort study SETTING: This study was conducted at Ochsner Medical Center, the largest tertiary-care teaching hospital in New Orleans, LA PARTICIPANTS: Patients undergoing catheter-based atrial fibrillation ablation INTERVENTIONS: The authors implemented a standardized heparin protocol, and enrolled 202 patients between November 2020 and March 2021. The historic controls consisted of 173 patients who underwent atrial fibrillation ablation between April 2020 and September 2020. Heparin administration in the control group was based on physician preference and was nonstandardized. MEASUREMENTS AND MAIN RESULTS: The primary endpoint was the percentage of intraprocedural ACTs in therapeutic range (≥300 to <450 s). Secondary endpoints included first measured ACT at ≥300 s and percent of measured ACTs in the supratherapeutic range (>450 s). Comparisons were performed using chi-squared tests or Fisher exact tests. Patients in the intervention group had a higher mean percentage of ACTs in the therapeutic range compared to the control group (84.9% vs. 75.8%, p<0.001). More patients in the intervention group reached therapeutic ACT on the first measurement compared to the control group (70.3% vs. 31.2%, p<0.001). CONCLUSION: During catheter-based cardiac ablation procedures, a novel standardized unfractionated heparin dosing protocol resulted in a higher percentage of ACTs in the target range, and a higher proportion of initial ACTs in the therapeutic range compared with baseline nonstandardized heparin dosing.

Hospitalization and Mortality among Black Patients and White Patients with Covid-19.

BACKGROUND: Many reports on coronavirus disease 2019 (Covid-19) have highlighted age- and sex-related differences in health outcomes. More information is needed about racial and ethnic differences in outcomes from Covid-19. METHODS: In this retrospective cohort study, we analyzed data from patients seen within an integrated-delivery health system (Ochsner Health) in Louisiana between March 1 and April 11, 2020, who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, the virus that causes Covid-19) on qualitative polymerase-chain-reaction assay. The Ochsner Health population is 31% black non-Hispanic and 65% white non-Hispanic. The primary outcomes were hospitalization and in-hospital death. RESULTS: A total of 3626 patients tested positive, of whom 145 were excluded (84 had missing data on race or ethnic group, 9 were Hispanic, and 52 were Asian or of another race or ethnic group). Of the 3481 Covid-19-positive patients included in our analyses, 60.0% were female, 70.4% were black non-Hispanic, and 29.6% were white non-Hispanic. Black patients had higher prevalences of obesity, diabetes, hypertension, and chronic kidney disease than white patients. A total of 39.7% of Covid-19-positive patients (1382 patients) were hospitalized, 76.9% of whom were black. In multivariable analyses, black race, increasing age, a higher score on the Charlson Comorbidity Index (indicating a greater burden of illness), public insurance (Medicare or Medicaid), residence in a low-income area, and obesity were associated with increased odds of hospital admission. Among the 326 patients who died from Covid-19, 70.6% were black. In adjusted time-to-event analyses, variables that were associated with higher in-hospital mortality were increasing age and presentation with an elevated respiratory rate; elevated levels of venous lactate, creatinine, or procalcitonin; or low platelet or lymphocyte counts. However, black race was not independently associated with higher mortality (hazard ratio for death vs. white race, 0.89; 95% confidence interval, 0.68 to 1.17). CONCLUSIONS: In a large cohort in Louisiana, 76.9% of the patients who were hospitalized with Covid-19 and 70.6% of those who died were black, whereas blacks comprise only 31% of the Ochsner Health population. Black race was not associated with higher in-hospital mortality than white race, after adjustment for differences in sociodemographic and clinical characteristics on admission.

Impact of presenting stroke severity and thrombolysis on outcomes following urgent carotid interventions.

BACKGROUND: Carotid interventions are increasingly performed in select patients following acute stroke. We aimed to determine the effects of presenting stroke severity (National Institutes of Health Stroke Scale [NIHSS]) and use of systemic thrombolysis (tissue plasminogen activator [tPA]) on discharge neurological outcomes (modified Rankin scale [mRS]) after urgent carotid endarterectomy (uCEA) and urgent carotid artery stenting (uCAS). METHODS: Patients undergoing uCEA/uCAS at a tertiary Comprehensive Stroke Center (January 2015 to May 2022) were divided into two cohorts: (1) no thrombolysis (uCEA/uCAS only) and (2) use of thrombolysis before the carotid intervention (tPA + uCEA/uCAS). Outcomes were discharge mRS and 30-day complications. Regression models were used to determine an association between tPA use and presenting stroke severity (NIHSS) and discharge neurological outcomes (mRS). RESULTS: Two hundred thirty-eight patients underwent uCEA/uCAS (uCEA/uCAS only, n = 186; tPA + uCEA/uCAS, n = 52) over 7 years. In the thrombolysis cohort compared with the uCEA/uCAS only cohort, the mean presenting stroke severity was higher (NIHSS = 7.6 vs 3.8; P = .001), and more patients presented with moderate to severe strokes (57.7% vs 30.2% with NIHSS >4). The 30-day stroke, death, and myocardial infarction rates in the uCEA/uCAS only vs tPA + uCEA/uCAS were 8.1% vs 11.5% (P = .416), 0% vs 9.6% (P < .001), and 0.5% vs 1.9% (P = .39), respectively. The 30-day stroke/hemorrhagic conversion and myocardial infarction rates did not differ with tPA use; however, the difference in deaths was significantly higher in the tPA + uCEA/uCAS cohort (P < .001). There was no difference in neurological functional outcome with or without thrombolysis use (mean mRS, 2.1 vs 1.7; P = .061). For both minor strokes (NIHSS ≤4 vs NIHSS >4: relative risk, 1.58 vs 1.58, tPA vs no tPA, respectively, P = .997) and moderate strokes (NIHSS ≤10 vs NIHSS >10: relative risk, 1.94 vs 2.08, tPA vs no tPA, respectively; P = .891), the likelihood of discharge functional independence (mRS score of ≤2) was not influenced by tPA. CONCLUSIONS: Patients with a higher presenting stroke severity (NIHSS) had worse neurological functional outcomes (mRS). Patients presenting with minor and moderate strokes were more likely to have discharge neurological functional independence (mRS of ≤2), regardless of whether they received tPA or not. Overall, presenting NIHSS is predictive of discharge neurological functional autonomy and is not influenced by the use of thrombolysis.

Neurologic outcomes of carotid and other emergent interventions for ischemic stroke over 6 years with dataset enhanced by machine learning.

BACKGROUND: The current mainstays of ischemic stroke treatment include the use of thrombolysis (tissue plasminogen activator [tPA]), urgent carotid endarterectomy (uCEA) or urgent carotid artery stenting (uCAS), and mechanical endovascular reperfusion/thrombectomy (MER). Scarce data describe the presenting stroke severity and neurologic outcomes for these acute ischemic stroke interventions, alone or in combination. The authors hypothesize that patients undergoing carotid interventions experience better functional neurologic outcomes than other stroke interventions. METHODS: A comprehensive stroke center dataset was combined with data for stroke-related procedures, comorbidities, complications, and physician documentation collected from electronic medical record data. A total of 10,975 patient encounter records from January 1, 2015, through July 31, 2021, were retrieved. The presenting stroke severity was determined by vascular/stroke neurologists using the National Institutes of Health Stroke Scale (NIHSS). Functional neurologic outcomes were reported using the modified Rankin scale (mRS) score, which quantifies the degree of neurologic disability. Because mRS values were only available for 3627 encounters in the original dataset, the authors developed a machine learning algorithm to analyze physician documentation and assign an mRS value. After the exclusion and machine learning analysis, a total of 5170 patient encounters were included for statistical analysis. Statistical analyses included the χ2 test, one-way analysis of variance and logistic regression on 30-day complications, stroke severity, and neurologic outcomes. RESULTS: Patients were divided into five cohorts: (1) uCEA or uCAS (n = 189), (2) tPA alone (n = 1053), (3) MER alone (n = 418), (4) tPA + MER (n = 199), and (5) no intervention (n = 3311). Patients undergoing uCEA/uCAS were significantly more likely to be male, smokers, and have a history of peripheral arterial disease compared with other stroke cohorts. The length of stay was shortest for patients who only received tPA or no intervention (6 days), followed by uCEA/uCAS (7.2 days), MER (10.2 days), and tPA + MER (8.8 days) cohorts (P < .001). The 30-day mortality was highest in the MER cohort (12.2%) and lowest in the uCEA/uCAS cohort (2.6%). The uCEA/uCAS cohort compared with other cohorts had the lowest presenting stroke severity (NIHSS 4.9 vs NIHSS 6.9-16.0), and best neurologic outcomes (mRS 1.7 vs mRS 1.8-2.6). CONCLUSIONS: After an ischemic stroke, patients undergoing urgent carotid interventions had the lowest presenting stroke severity (NIHSS) and highest rate of independent neurologic outcomes (mRS) compared with other stroke interventions. Incoming stroke severity correlates with functional neurologic outcomes, and patients who present with an NIHSS of 10 or less who undergo uCEA/uCAS have a high likelihood of independent neurologic functional outcome (mRS of ≤2).

Correlation of Gastrointestinal Symptoms at Initial Presentation with Clinical Outcomes in Hospitalized COVID-19 Patients: Results from a Large Health System in the Southern USA.

BACKGROUND: We aimed to understand the association of gastrointestinal (GI) symptoms at initial presentation with clinical outcomes during COVID-19 hospitalization. METHODS: This retrospective, multicenter cohort study included consecutive hospitalized COVID-19 patients from a single, large health system. The presence of GI symptoms was assessed at initial presentation and included one or more of the following: nausea, vomiting, diarrhea and abdominal pain. Patients were divided into three cohorts: Only GI symptoms, GI and non-GI symptoms and only non-GI symptoms. The primary outcome was association of GI symptoms with mortality. Secondary outcomes included prevalence of GI symptoms and survival analysis. RESULTS: A total of 1672 COVID-19 patients were hospitalized (mean age: 63 ± 15.8 years, females: 50.4%) in our system during the study period. 40.7% patients had at least one GI symptom (diarrhea in 28.3%, nausea/vomiting in 23%, and abdominal pain in 8.8% patients), and 2.6% patients had only GI symptoms at initial presentation. Patients presenting with GI symptoms (with or without non-GI symptoms) had a lower mortality rate compared to patients presenting with only non-GI symptoms (20% vs. 26%; p < 0.05). The time from hospitalization to being discharged was less for patients presenting with only GI symptoms (7.4 days vs. > 9 days, p < 0.0014). After adjusting for other factors, the presence of GI symptoms was not associated with mortality (p > 0.05). CONCLUSION: Among a hospitalized COVID-19 positive Southern US population, 41% patients presented with either diarrhea, nausea, vomiting or abdominal pain initially. The presence of GI symptoms has no association with in-hospital all-cause mortality.

Racial and Workplace Disparities in Seroprevalence of SARS-CoV-2, Baton Rouge, Louisiana, USA.

By using paired molecular and antibody testing for severe acute respiratory syndrome coronavirus 2 infection, we determined point prevalence and seroprevalence in Louisiana, USA, during the second phase of reopening. Infections were highly variable by race and ethnicity, work environment, and ZIP code. Census-weighted seroprevalence was 3.6%, and point prevalence was 3.0%.

Multivariate mortality analyses in COVID-19: Comparing patients with cancer and patients without cancer in Louisiana.

BACKGROUND: This is the largest and only multivariate study evaluating the difference in mortality from coronavirus disease 2019 (COVID-19) between patients with cancer and patients without cancer in the United States. The objective was to assess COVID-19 mortality rates in patients with cancer versus patients without cancer and uncover possible statistically significant characteristics contributing to mortality. METHODS: This retrospective study analyzed patients with cancer and patients without cancer who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from March 1 through April 30, 2020. This was a multicenter study in the state of Louisiana throughout the Ochsner Health System in both tertiary and nontertiary centers. Patients older than 18 years were eligible. Three hundred twelve patients with cancer were compared with 4833 patients without cancer. RESULTS: Mortality was found to be higher in the cancer group. Patients of advanced age with cancer had a significant increase in mortality (odds ratio [OR], 5.96; P < .001). Other significant risk factors for increased mortality were male sex (OR, 2.15), a history of chronic kidney disease (OR, 3.84), and obesity (OR, 1.30). In hospitalized patients with cancer, adverse vital signs on admission, decreased absolute lymphocyte counts, thrombocytopenia, elevated creatinine, lactic acidosis, and elevated procalcitonin all seemed to increase the risk of death. Among patients with cancer, active or progressive disease (P < .001) and recent therapy (OR, 2.34; 95% confidence interval, 1.08-5.08) were shown to increase mortality. CONCLUSIONS: Patients with cancer have increased mortality in the setting of infection with SARS-CoV-2 in comparison with patients without cancer. Patients with cancer who are 65 years of age or older and those with certain comorbidities have the greatest risk of death. Recent cancer-directed therapy and disease status also seem to play roles in mortality. LAY SUMMARY: This is the largest study of patients with cancer versus patients without cancer to date and is the first multivariate analysis study comparing these 2 patient populations. This study confirms the hypothesis that patients with cancer are at increased risk for mortality and that there are multiple characteristics posing the potential to risk-stratify these patients in the setting of a future outbreak.

A pediatric surgeon's dilemma: does cholecystectomy improve symptoms of biliary dyskinesia?

BACKGROUND: Biliary dyskinesia (BD) is a well-established gallbladder pathology in adult patients and rates of cholecystectomy for BD continue to rise in the United States. Many pediatric patients with vague abdominal pain of variable duration are evaluated for biliary dyskinesia. It remains unknown which cohort of pediatric patients diagnosed with BD are most likely to have sustained improvement in symptoms following laparoscopic cholecystectomy. We aimed to determine whether cholecystectomy resulted in symptom relief and led to a reduction in the number of medical visits related to gastrointestinal (GI) symptoms after surgery. METHODS: We performed a multi-institution retrospective review of all children < 18 years of age who underwent laparoscopic cholecystectomy for BD between January 2013 and April 2018 in our hospital system. GI symptoms and clinical visits related to a GI complaint were assessed preoperatively. Patients were followed for 2 years after surgery. At 6 months and 2 years postoperatively, symptoms and the rate of medical visits related to a GI complaint were quantified and compared to the preoperative values. RESULTS: In total, 45 patients met our inclusion criteria. Of these, 82% of patients were female. The average age was 14 years old (± 2.6) and 56% of patients met the criteria for being overweight or obese. The mean gallbladder ejection fraction was 13% (± 10.8). All patients had abdominal pain, 82% (37/45) presented with nausea, and 51% (23/45) presented with post-prandial pain. Six months postoperatively, 58% of patients experienced resolution of their abdominal pain which decreased to 38% of patients after 2 years. Similarly, 59% had resolution of their nausea at 6 months compared to 43% at 2 years, and 100% had resolution of their post-prandial pain at 6 months compared to 91% at 2 years. The total number of clinical visits related to a GI complaint decreased from 2.6 (± 2.4) preoperatively to 1.0 (± 1.3) within 6 months postoperatively. When followed to 2 years postoperatively, the 6-month rate of clinical visits related to a GI complaint decreased from a mean of 2.6 preoperatively to 0.71 following surgery. CONCLUSIONS: Following cholecystectomy, we observed a high percentage of durable symptom resolution in those patients with BD who presented with post-prandial pain. Patients with non-food-related abdominal pain, with or without nausea and vomiting, had a lower rate of symptom resolution after surgery and the rate declined with time. For patients without post-prandial pain, evaluation and treatment of alternative sources of pain should be considered prior to surgery. Regardless of their presenting symptoms, patients who underwent surgery for BD had fewer clinical GI-related visits after surgery. However, no specific gallbladder ejection fraction or symptom alone was predictive of a lower rate of clinical visits postoperatively.

Clinical Effectiveness of Decision Support for Prescribing Opioids for Chronic Noncancer Pain: A Prospective Cohort Study.

OBJECTIVES: This prospective cohort study examines the clinical effectiveness of electronic medical record clinical decision support (EMR CDS) for opioid prescribing. METHODS: Data analysis included primary care patients with chronic opioid therapy for noncancer pain seen within an integrated health delivery system in Louisiana between January 2017 and October 2018. EMR CDS incorporated an opioid health maintenance tool to display the status of risk mitigation, and the medication order embedded the morphine equivalent daily dose (MEDD) calculator and a hyperlink to the Louisiana pharmacy drug monitoring program. Outcome measures included change in the average MEDD and rates of opioid risk mitigation, hospitalization, and emergency department use. RESULTS: Among 14 221 patients, 9% had prescriptions with an average MEDD ≥90 mg. There were no significant changes in MEDD after EMR CDS implementation. Increasing age, Charlson Comorbidity Index score, female sex, black non-Hispanic race, non-opioid pain medication co-prescriptions, and specialty referrals were associated with a lower odds of MEDD ≥90 (high-dose threshold). Medicare or self-pay, substance abuse history, and pain agreements were associated with increased odds of prescribing above this high-dose threshold. After incorporation of EMR CDS, patients had higher rates of urine drug screens (17% vs 7%) and naloxone prescriptions (3% vs 1%, all P < .001). In addition, specialty referrals to physical or occupational therapy, orthopedics, neurology, and psychiatry or psychology increased in the postintervention period. Although emergency department use decreased (rate ratio 0.92; 95% confidence interval 0.89-0.95), hospitalization rates did not change. CONCLUSIONS: EMR CDS improved adherence to opioid risk mitigation strategies. Further research examining which practice redesign interventions effectively reduce high-dose opioid prescribing is needed.

Acute thrombotic thrombocytopenic purpura in Louisiana: Seasonal distribution and evaluation of an ADAMTS13 order screening protocol.

BACKGROUND: Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disorder caused by inactivation of ADAMTS13. It is characterized by thrombocytopenia and microangiopathic hemolytic anemia. Previous studies have produced conflicting data regarding seasonal association of TTP diagnoses. This study evaluated the seasonal distribution of acute TTP in southern Louisiana. Additionally, this study timeline overlapped with the initiation of a new screening protocol for ADAMTS13 testing. STUDY DESIGN AND METHODS: A retrospective analysis of patients receiving ADAMTS13 testing at Ochsner Medical Center from January 2010 to December 2017 was performed. TTP patient episodes were defined by ADAMTS13 activity <10%. Episodes were plotted according to season of presentation and a chi-square analysis was performed. Data of identified TTP patients was analyzed to evaluate for confounding variables. ADAMTS13 order volumes and results before and after screening protocol implementation were compared. RESULTS: Two hundred and fifty-two ADAMTS13 tests were ordered on 245 unique patients. Twenty-five patients had ADAMTS13 activity <10%. No significant differences in seasonal TTP case distribution were identified. Patients with confirmed TTP were younger and more likely to be Black or African American. A screening protocol did not decrease the number of annual ADAMTS13 test orders in our time frame, but was associated with a nonsignificant increase in the percentage of positive results. CONCLUSION: No significant seasonal distribution of TTP was identified in our population. This analysis provides previously unexamined regional information regarding this diagnosis. The number of tests ordered after the implementation of the screening protocol increased, corresponding with our facility's expanding reach.

Mood and quality of life changes in pregnancy and postpartum and the effect of a behavioral intervention targeting excess gestational weight gain in women with overweight and obesity: a parallel-arm randomized controlled pilot trial.

BACKGROUND: Intensive lifestyle interventions in pregnancy have shown success in limiting gestational weight gain, but the effects on mood and quality of life in pregnancy and postpartum are less known. The purpose was to quantify changes in mental and physical quality of life and depressive symptoms across pregnancy and the postpartum period, to determine the association between gestational weight gain and change in mood and quality of life, and to assess the effect of a behavioral intervention targeting excess gestational weight gain on these outcomes. METHODS: A three group parallel-arm randomized controlled pilot trial of 54 pregnant women who were overweight or obese was conducted to test whether the SmartMoms® intervention decreased the proportion of women with excess gestational weight gain. Individuals randomized to Usual Care (n = 17) did not receive any weight management services from interventionists. Individuals randomized to the SmartMoms® intervention (n = 37) were provided with behavioral weight management counseling by interventionists either in clinic (In-Person, n = 18) or remotely through a smartphone application (Phone, n = 19). In a subset of 43 women, mood and mental and physical quality of life were assessed with the Beck Depression Inventory-II and the Rand 12-Item short form, respectively, in early pregnancy, late pregnancy, 1-2 months postpartum, and 12 months postpartum. RESULTS: The SmartMoms® intervention and Usual Care groups had higher depressive symptoms (p < 0.03 for SmartMoms® intervention, p < 0.01 for Usual Care) and decreased physical health (p < 0.01) from early to late pregnancy. Both groups returned to early pregnancy mood and physical quality of life postpartum. Mental health did not change from early to late pregnancy (p = 0.8), from early pregnancy to 1-2 months (p = 0.5), or from early pregnancy to 12 months postpartum (p = 0.9), respectively. There were no significant intervention effects. Higher gestational weight gain was associated with worsened mood and lower physical quality of life across pregnancy. CONCLUSION: High depressive symptoms and poor quality of life may be interrelated with the incidence of excess gestational weight gain. The behavioral gestational weight gain intervention did not significantly impact these outcomes, but mood and quality of life should be considered within future interventions and clinical practice to effectively limit excess gestational weight gain.

Efficacy of a school-based obesity prevention intervention at reducing added sugar and sodium in children's school lunches: the LA Health randomized controlled trial.

BACKGROUND: Decreasing selection and consumption of sodium and added sugars in the school cafeteria setting is important to provide optimal nutrition to children. OBJECTIVE: The ofjective of this study is to determine whether Louisiana (LA) Health, a school-based obesity prevention intervention, could successfully reduce children's selection and consumption of sodium and added sugars during school lunches vs. the control group. DESIGN: Food selection, consumption, and plate waste from student lunches (3 consecutive days) in 33 public schools in rural Louisiana were collected and analyzed using the digital photography of foods method at baseline and after a 28-month obesity prevention intervention (LA Health) beginning in 4th-6th grade (87% of children received free or reduced cost lunch). Selection and consumption of energy, added sugar, and sodium was objectively measured using digital photography of foods. Mixed models, including Race and BMI, were used to determine whether change in selection and consumption differed by group. RESULTS: Sodium decreased for selection (- 233.1 ± 89.4 mg/lunch, p = 0.04) and consumption (- 206.3 ± 65.9, mg/lunch) in the intervention (vs. control) by month 18, and in consumption by month 28 (- 153.5 ± 66.9 mg/lunch, p = 0.03). Change in added sugar consumption decreased in the intervention (vs. control) at month 18 (- 3.7 ± 1.6, p = 0.05) and at month 28 (- 3.5 ± 1.6 tsp/lunch, p = 0.05). CONCLUSIONS: LA Health decreased the amount of added sugar and sodium selected and consumed, but not plate waste, by month 28. Results highlight the importance of long-term interventions and policies targeting provision and selection to improve dietary patterns in children, with less focus on plate waste.

Outpatient Complex Case Management: Health System-Tailored Risk Stratification Taxonomy to Identify High-Cost, High-Need Patients.

BACKGROUND: U.S. health systems, incentivized by financial penalties, are designing programs such as case management to reduce service utilization among high-cost, high-need populations. The major challenge is identifying patients for whom targeted programs are most effective for achieving desired outcomes. OBJECTIVE: To evaluate a health system's outpatient complex case management (OPCM) for Medicare beneficiaries for patients overall and for high-risk patients using system-tailored taxonomy, and examine whether OPCM lowers service utilization and healthcare costs. DESIGN: Retrospective case-control study using Medicare data collected between 2012 and 2016 for Ochsner Health System. PARTICIPANTS: Super-utilizers defined as Medicare patients with at least two hospital/ED encounters within 180 days of the index date including the index event. INTERVENTION: Outpatient complex case management. MAIN MEASURES: Propensity score-adjusted multivariable logistic regression analysis was conducted for primary outcomes (90-day hospital readmission; 90-day ED re-visit). A difference-in-difference analysis was conducted to examine changes in per membership per month (PMPM) costs based on OPCM exposure. KEY RESULTS: Among 18,882 patients, 1197 (6.3%) were identified as "high-risk" and 470 (2.5%) were OPCM participants with median enrollment of 49 days. High-risk OPCM cases compared to high-risk controls had lower odds of 90-day hospital readmissions (0.81 [0.40-1.61], non-significant) and lower odds of 90-day ED re-visits (0.50 [0.32-0.79]). Non-high-risk OPCM cases compared to non-high-risk controls had lower odds of 90-day hospital readmissions (0.20 [0.11-0.36]) and 90-day ED re-visits (0.66 [0.47-0.94]). Among OPCM cases, high-risk patients compared to non-high-risk patients had greater odds of 90-day hospital readmissions (4.44 [1.87-10.54]); however, there was no difference in 90-day ED re-visits (0.99 [0.58-1.68]). Overall, OPCM cases had lower total cost of care compared to controls (PMPM mean [SD]: - $1037.71 [188.18]). CONCLUSIONS: Use of risk stratification taxonomy for super-utilizers can identify patients most likely to benefit from case management. Future studies must further examine which OPCM components drive improvements in select outcome for specific populations.

Food Photography Is Not an Accurate Measure of Energy Intake in Obese, Pregnant Women.

Background: To improve weight management in pregnant women, there is a need to deliver specific, data-based recommendations on energy intake. Objective: This cross-sectional study evaluated the accuracy of an electronic reporting method to measure daily energy intake in pregnant women compared with total daily energy expenditure (TDEE). Methods: Twenty-three obese [mean ± SEM body mass index (kg/m2): 36.9 ± 1.3] pregnant women (aged 28.3 ±1.1 y) used a smartphone application to capture images of their food selection and plate waste in free-living conditions for ≥6 d in early (13-16 wk) and late (35-37 wk) pregnancy. Energy intake was evaluated by the smartphone application SmartIntake and compared with simultaneous assessment of TDEE obtained by doubly labeled water. Accuracy was defined as reported energy intake compared with TDEE (percentage of TDEE). Ecological momentary assessment prompts were used to enhance data reporting. Two-one-sided t tests for the 2 methods were used to assess equivalency, which was considered significant when accuracy was >80%. Results: Energy intake reported by the SmartIntake application was 63.4% ± 2.3% of TDEE measured by doubly labeled water (P = 1.00). Energy intake reported as snacks accounted for 17% ± 2% of reported energy intake. Participants who used their own phones compared with participants who used borrowed phones captured more images (P = 0.04) and had higher accuracy (73% ± 3% compared with 60% ± 3% of TDEE; P = 0.01). Reported energy intake as snacks was significantly associated with the accuracy of SmartIntake (P = 0.03). To improve data quality, excluding erroneous days of likely underreporting (<60% TDEE) improved the accuracy of SmartIntake, yet this was not equivalent to TDEE (-22% ± 1% of TDEE; P = 1.00). Conclusions: Energy intake in obese, pregnant women obtained with the use of an electronic reporting method (SmartIntake) does not accurately estimate energy intake compared with doubly labeled water. However, accuracy improves by applying criteria to eliminate erroneous data. Further evaluation of electronic reporting in this population is needed to improve compliance, specifically for reporting frequent intake of small meals. This trial was registered at www.clinicaltrials.gov as NCT01954342.

Pomegranate juice and extract extended lifespan and reduced intestinal fat deposition in Caenorhabditis elegans.

Pomegranate juice with a high content of polyphenols, pomegranate extract, ellagic acid, and urolithin A, have anti-oxidant and anti-obesity effects in humans. Pomegranate juice extends lifespan of Drosophila melanogaster. Caenorhabditis elegans (C. elegans) (n = 6) compared to the control group in each treatment, lifespan was increased by pomegranate juice in wild type (N2, 56 %, P < 0.001) and daf-16 mutant (daf-16(mgDf50)I) (18 %, P = 0.00012), by pomegranate extract in N2 (28 %, P = 0.00004) and in daf-16(mgDf50)I (10 %, P < 0.05), or by ellagic acid (11 %, P < 0.05). Pomegranate juice reduced intestinal fat deposition (IFD) in C. elegans (n = 10) N2 (-68 %, P = 0.0003) or in the daf-16(mgDf50)I (-33 %, P = 0.0034). The intestinal fat deposition was increased by pomegranate extract in N2 (137 %, P < 0.0138) and in daf-16(mgDf50)I (26 %, P = 0.0225), by ellagic acid in N2 (66 %, P < 0.0001) and in daf-16(mgDf50)I (74 %, P < 0.0001), or by urolithin A in N2 (57 %, P = 0.0039) and in daf-16(mgDf50)I (43 %, P = 0.0001). These effects were partially mediated by the daf-16 pathway. The data may offer insights to human aging and obesity due to homology with C. elegans.

Racial Differences in Strength of Associations Between Colorectal Cancer Screening, Area Deprivation, Demographics, and Clinical Characteristics.

Background: In Louisiana, colorectal cancer (CRC) incidence and mortality exceed national rates. Census tract, sex, and racial disparities across the state are well documented. This study examined whether there were subpopulation differences in associations between CRC screening, area deprivation index (ADI), and patient characteristics. Methods: This retrospective observational study included patients aged 50 to 75 years who received care within Ochsner Health in Louisiana between July 1, 2012, and December 31, 2020. Logistic regression models were used to generate adjusted odds ratios (95% CI). Results: A total of 75,344 patients met eligibility criteria for inclusion in the data analysis (60% female, 36% Black, 56% with spouse/partner, 42% Medicare/Medicaid,17% living in high deprivation areas, 41% with 2+ chronic conditions, 56% never smoked, 51% obese). Living in areas with less deprivation (state decile 1-3 vs 8-10: 1.19 [1.14-1.24]), number of comorbidities (3+ conditions: 1.15 [1.12-1.17]), and prior outpatient visits (1.63 [1.58-1.67]) increased odds of CRC screening. Male sex (0.82 [0.79-0.84]), age group 55 to 59 years (0.97 [0.95-0.99]), and Medicaid insurance (0.89 [0.86-0.92]) decreased odds of screening. ADI was collinear with sex, race, marital status, body mass index, and smoking status. In subgroup analyses, between-group differences in strength of associations of CRC screening with ADI and patient characteristics varied most prominently by race. Conclusion: There may be an unmeasured social context explaining persistent racial differences among factors associated with CRC screening. A combination of census tract and individual-level social determinants may guide population health management for at-risk subpopulations.

An Analysis of the Timing for Closure of a Diverting Loop Ileostomy.

A diverting loop ileostomy (DLI) is used to protect a distal gastrointestinal anastomosis at risk of leakage. While patients typically prefer early DLI closure, surgeons vary in opinion regarding optimal timing. This study evaluated whether the timing of DLI closure impacts outcomes.A retrospective review was performed on patients who underwent DLI creation within one health care system between 2012 and 2020. Patient characteristics and postoperative outcomes were compared across ileostomies closed in ≤2 months, 2-4 months, and >4 months. Outcomes examined included anastomotic leak, other complications, reintervention, and death within 30 days.A total of 500 DLIs were analyzed for the study, 455 of which were closed. The three closure groups were similar in patient characteristics and comorbidities. None of the outcome variables analyzed in this study demonstrated a statistically significant difference between groups, suggesting that in patients otherwise fit for surgery, DLI closure can be safely performed within 2 months of creation.

Racial Differences and Social Determinants of Health in Achieving Hypertension Control.

OBJECTIVE: To investigate whether specific social determinants of health could be a "health barrier" toward achieving blood pressure (BP) control and to further evaluate any differences between Black patients and White patients. PATIENTS AND METHODS: We conducted a retrospective cohort study of 3305 patients with elevated BP who were enrolled in a hypertension digital medicine program for at least 60 days and followed up for up to 1 year. Patients were managed virtually by a dedicated hypertension team who provided guideline-based medication management and lifestyle support to achieve goal BP. RESULTS: Compared with individuals without any health barriers, the addition of 1 barrier was associated with lower probability of control at 1 year from 0.73 to 0.60 and to 0.55 in those with 2 or more barriers. Health barriers were more prevalent in Black patients than in those who were White (44.6% [482 of 1081] vs 31.3% [674 of 2150]; P<.001). There was no difference at all in BP control between Black individuals and those who were White if 2 or more barriers were present. CONCLUSION: Patient-related health barriers are associated with BP control. Black patients with poorly controlled hypertension have a higher prevalence of health barriers than their White counterparts. When 2 or more health barriers were present, there was no differences in BP control between White and Black individuals.

Evaluation of Spending Differences Between Beneficiaries in Medicare Advantage and the Medicare Shared Savings Program.

Importance: The 2 primary efforts of Medicare to advance value-based care are Medicare Advantage (MA) and the fee-for-service-based Medicare Shared Savings Program (MSSP). It is unknown how spending differs between the 2 programs after accounting for differences in patient clinical risk. Objective: To examine how spending and utilization differ between MA and MSSP beneficiaries after accounting for differences in clinical risk using data from administrative claims and electronic health records. Design, Setting, and Participants: This retrospective economic evaluation used data from 15 763 propensity score-matched beneficiaries who were continuously enrolled in MA or MSSP from January 1, 2014, to December 31, 2018, with diabetes, congestive heart failure (CHF), chronic kidney disease (CKD), or hypertension. Participants received care at a large nonprofit academic health system in the southern United States that bears risk for Medicare beneficiaries through both the MA and MSSP programs. Differences in beneficiary risk were mitigated by propensity score matching using validated clinical criteria based on data from administrative claims and electronic health records. Data were analyzed from January 2019 to May 2022. Exposures: Enrollment in MA or attribution to an accountable care organization in the MSSP program. Main Outcomes and Measures: Per-beneficiary annual total spending and subcomponents, including inpatient hospital, outpatient hospital, skilled nursing facility, emergency department, primary care, and specialist spending. Results: The sample of 15 763 participants included 12 720 (81%) MA and 3043 (19%) MSSP beneficiaries. MA beneficiaries, compared with MSSP beneficiaries, were more likely to be older (median [IQR] age, 75.0 [69.9-81.8] years vs 73.1 [68.3-79.8] years), male (5515 [43%] vs 1119 [37%]), and White (9644 [76%] vs 2046 [69%]) and less likely to live in low-income zip codes (2338 [19%] vs 750 [25%]). The mean unadjusted per-member per-year spending difference between MSSP and MA disease-specific subcohorts was $2159 in diabetes, $4074 in CHF, $2560 in CKD, and $2330 in hypertension. After matching on clinical risk and demographic factors, MSSP spending was higher for patients with diabetes (mean per-member per-year spending difference in 2015: $2454; 95% CI, $1431-$3574), CHF ($3699; 95% CI, $1235-$6523), CKD ($2478; 95% CI, $1172-$3920), and hypertension ($2258; 95% CI, $1616-2,939). Higher MSSP spending among matched beneficiaries was consistent over time. In the matched cohort in 2018, MSSP total spending ranged from 23% (CHF) to 30% (CKD) higher than MA. Adjusting for differential trends in coding intensity did not affect these results. Higher outpatient hospital spending among MSSP beneficiaries contributed most to spending differences between MSSP and MA, representing 49% to 62% of spending differences across disease cohorts. Conclusions and Relevance: In this study, utilization and spending were consistently higher for MSSP than MA beneficiaries within the same health system even after adjusting for granular metrics of clinical risk. Nonclinical factors likely contribute to the large differences in MA vs MSSP spending, which may create challenges for health systems participating in MSSP relative to their participation in MA.
