RESUMO
BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has evolved as the standard for treating complicated acute type B aortic dissection (ATBAD). Acute kidney injury (AKI) is a common complication in critically ill patients and is commonly observed in patients with ATBAD. The purpose of the study was to characterize AKI after TEVAR. METHODS: All patients who underwent TEVAR for ATBAD from 2011 through 2021 were identified using the International Registry of Acute Aortic Dissection. The primary end point was AKI. A generalized linear model analysis was performed to identify a factor associated with postoperative AKI. RESULTS: A total of 630 patients presented with ATBAD and underwent TEVAR. The indication for TEVAR was complicated ATBAD in 64.3%, high-risk uncomplicated ATBAD in 27.6%, and uncomplicated ATBAD in 8.1%. Of 630 patients, 102 (16.2%) developed postoperative AKI (AKI group) and 528 patients (83.8%) did not (non-AKI group). The most common indication for TEVAR was malperfusion (37.5%). In-hospital mortality was significantly higher in the AKI group (18.6% vs 4%; P < .001). Postoperatively, cerebrovascular accident, spinal cord ischemia, limb ischemia, and prolonged ventilation were more commonly observed in the AKI group. The expected mortality was similar at 2 years between the two groups (P = .51). Overall, the preoperative AKI was observed in 95 (15.7%) in the entire cohort consisting of 60 (64.5%) in the AKI group and 35 (6.8%) in the non-AKI group. A history of CKD (odds ratio, 4.6; 95% confidence interval, 1.5-14.1; P = .01) and preoperative AKI (odds ratio, 24.1; 95% confidence interval, 10.6-55.0; P < .001) were independently associated with postoperative AKI. CONCLUSIONS: The incidence of postoperative AKI was 16.2% in patients undergoing TEVAR for ATBAD. Patients with postoperative AKI had a higher rate of in-hospital morbidities and mortality than those without. A history of CKD and preoperative AKI were independently associated with postoperative AKI.

OBJECTIVE: To describe the trends in management and outcomes of patients with acute type B aortic dissection in the International Registry of Acute Aortic Dissection. METHODS: From 1996 - 2022, 3 908 patients were divided into similar sized quartiles (T1, T2, T3, and T4). In hospital outcomes were analysed for each quartile. Survival rates following admission were compared using Kaplan-Meier analyses with Mantel-Cox Log rank tests. RESULTS: Endovascular treatment increased from 19.1% in T1 to 37.2% in T4 (ptrend < .001). Correspondingly, medical therapy decreased from 65.7% in T1 to 54.0% in T4 (ptrend < .001), and open surgery from 14.8% in T1 to 7.0% in T4 (ptrend < .001). In hospital mortality decreased in the overall cohort from 10.7% in T1 to 6.1% in T4 (ptrend < .001), as well as in medically, endovascularly and surgically treated patients (ptrend = .017, .033, and .011, respectively). Overall post-admission survival at three years increased (T1: 74.8% vs. T4: 77.3%; p = .006). CONCLUSION: Considerable changes in the management of acute type B aortic dissection were observed over time, with a significant increase in the use of endovascular treatment and a corresponding reduction in open surgery and medical management. These changes were associated with a decreased overall in hospital and three year post-admission mortality rate among quartiles.
RESUMO
Direct oral anticoagulant (DOAC) starter packs are designed for unique treatment dosing for acute venous thromboembolism (VTE). Inappropriate use of 30-day DOAC starter packs in patients with atrial fibrillation (AF) may increase the risk for bleeding events given higher dosing in the first 1-3 weeks of treatment. A retrospective analysis of medical and outpatient pharmacy claims data from 2015 to 2018 in Optum's De-identified Clinformatics® Data Mart was performed. Patients greater than 18 years of age with AF and a new prescription of apixaban or rivaroxaban were included. Patients with an acute VTE were excluded. The main outcome of interest was adverse events (emergency department [ED] visits, hospitalizations, and deaths within 90 days after prescription fill date) associated with inappropriate DOAC starter pack prescription. A total of 90,950 DOAC-treated patients with AF were identified. The mean age was 74.5 years (SD 10.0) and 42,717 (47.0%) were female. Inappropriate starter packs were used by 117 (0.1%) patients, who were younger than non-starter pack patients (71.3 years vs. 74.5 years). Patients who received an inappropriate DOAC prescription were more likely to identify as Black (12.0% vs. 8.8%). Rates of ED visits, hospitalizations, and deaths overall were numerically lower in patients with starter pack compared to non-starter pack DOAC prescriptions. In contrast, rates of ED visits and hospitalizations related to significant bleeding were numerically higher in patients with starter pack compared to non-starter pack DOAC prescriptions. Among patients with AF but no VTE, those who received an inappropriate DOAC starter pack had numerically higher rates of severe bleeding leading to ED visits and hospitalizations compared to those prescribed an appropriate non-starter pack DOAC anticoagulant.

BACKGROUND: Cannulation strategy in acute type A dissection (ATAD) varies widely without known gold standards. This study compared ATAD outcomes of axillary vs femoral artery cannulation in a large cohort from the International Registry of Acute Aortic Dissection (IRAD). METHODS: The study retrospectively reviewed 2145 patients from the IRAD Interventional Cohort (1996-2021) who underwent ATAD repair with axillary or femoral cannulation (axillary group: n = 1106 [52%]; femoral group: n = 1039 [48%]). End points included the following: early mortality; neurologic, respiratory, and renal complications; malperfusion; and tamponade. All outcomes are presented as axillary with respect to femoral. RESULTS: The proportion of patients younger than 70 years in both groups was similar (n = 1577 [74%]), as were bicuspid aortic valve, Marfan syndrome, and previous dissection. Patients with femoral cannulation had slightly more aortic insufficiency (408 [55%] vs 429 [60%]; P = .058) and coronary involvement (48 [8%] vs 70 [13%]; P = .022]. Patients with axillary cannulation underwent more total aortic arch (156 [15%] vs 106 [11%]; P = .02) and valve-sparing root replacements (220 [22%] vs 112 [12%]; P < .001). More patients with femoral cannulation underwent commissural resuspension (269 [30.9%] vs 324 [35.3%]; P = .05). Valve replacement rates were not different. The mean duration of cardiopulmonary bypass was longer in the femoral group (190 [149-237] minutes vs 196 [159-247] minutes; P = .037). In-hospital mortality was similar between the axillary (n = 165 [15%]) and femoral (n = 149 [14%]) groups (P = .7). Furthermore, there were no differences in stroke, visceral ischemia, tamponade, respiratory insufficiency, coma, or spinal cord ischemia. CONCLUSIONS: Axillary cannulation is associated with a more stable ATAD presentation, but it is a more extensive intervention compared with femoral cannulation. Both procedures have equivalent early mortality, stroke, tamponade, and malperfusion outcomes after statistical adjustment.

OBJECTIVES: Thoracic endovascular aortic repair is the method of choice in patients with complicated type B acute aortic dissection. However, thoracic endovascular aortic repair carries a risk of periprocedural neurological events including stroke and spinal cord ischemia. We aimed to look at procedure-related neurological complications within a large cohort of patients with type B acute aortic dissection treated by thoracic endovascular aortic repair. METHODS: Between 1996 and 2021, the International Registry of Acute Aortic Dissection collected data on 3783 patients with type B acute aortic dissection. For this analysis, 648 patients with type B acute aortic dissection treated by thoracic endovascular aortic repair were included (69.4% male, mean age 62.7 ± 13.4 years). Patients were excluded who presented with a preexisting neurologic deficit or received adjunctive procedures. Demographics, clinical symptoms, and outcomes were analyzed. The primary end point was the periprocedural incidence of neurological events (defined as stroke, spinal cord ischemia, transient neurological deficit, or coma). Predictors for perioperative neurological events and follow-up outcomes were considered as secondary end points. RESULTS: Periprocedure neurological events were noted in 72 patients (11.1%) and included strokes (n = 29, 4.6%), spinal cord ischemias (n = 21, 3.3%), transient neurological deficits (n = 16, 2.6%), or coma (n = 6, 1.0%). The group with neurological events had a significantly higher in-hospital mortality (20.8% vs 4.3%, P < .001). Patients with neurological events were more likely to be female (40.3% vs 29.3%, P = .077), and aortic rupture was more often cited as an indication for thoracic endovascular aortic repair (38.8% vs 16.5%, P < .001). In patients with neurological events, more stent grafts were used (2 vs 1 stent graft, P = .002). Multivariable logistic regression analysis showed that aortic rupture (odds ratio, 3.12, 95% confidence interval, 1.44-6.78, P = .004) and female sex (odds ratio, 1.984, 95% confidence interval, 1.031-3.817, P = .040) were significantly associated with perioperative neurological events. CONCLUSIONS: In this highly selected group from dedicated aortic centers, more than 1 in 10 patients with type B acute aortic dissection treated by thoracic endovascular aortic repair had neurological events, in particular women. Further research is needed to identify the causes and presentation of these events after thoracic endovascular aortic repair, especially among women.

OBJECTIVE: With an aging population and advancements in imaging, recurrence of thoracic aortic dissection is becoming more common. METHODS: All patients enrolled in the International Registry of Aortic Dissection from 1996 to 2023 with type A and type B acute aortic dissection were identified. Among them, initial dissection and recurrent dissection were discerned. The study period was categorized into 3 eras: historic era, 1996 to 2005; middle era, 2006 to 2015; most recent era, 2016 to 2023. Propensity score matching was applied between initial dissection and recurrent dissection. Outcome of interests included long-term survival and cumulative incidence of major aortic events defined by the composite of reintervention, aortic rupture, and new dissection. RESULTS: The proportion of recurrent dissection increased from 5.9% in the historic era to 8.0% in the most recent era in the entire dissection cohort. In patients with type A dissection, propensity score matching between initial dissection and recurrent dissection yielded 326 matched pairs. Kaplan-Meier curves showed similar long-term survival between the 2 groups. However, the cumulative incidence of major aortic events was significantly higher in the recurrent dissection group (40.3% ± 6.2% vs 17.8% ± 5.1% at 4 years in the initial dissection group, P = .02). For type B dissection, 316 matched pairs were observed after propensity score matching. Long-term survival and the incidence of major aortic events were equivalent between the 2 groups. CONCLUSIONS: The case volume of recurrent dissection or the ability to detect recurrent dissection has increased over time. Acute type A recurrent dissection was associated with a higher risk of major aortic events than initial dissection. Further judicious follow-up may be crucial after type A recurrent dissection.
RESUMO
BACKGROUND: Over the past 25 years, diagnosis and therapy for acute aortic dissection (AAD) have evolved. We aimed to study the effects of these iterative changes in care. METHODS: Patients with nontraumatic AAD enrolled in the International Registry of Acute Aortic Dissection (61 centers; 15 countries) were divided into time-based tertiles (groups) from 1996 to 2022. The impact of changes in diagnostics, therapeutic care, and in-hospital and 3-year mortality was assessed. Cochran-Armitage trend and Jonckheere-Terpstra tests were conducted to test for any temporal trend. RESULTS: Each group consisted of 3785 patients (mean age, ≈62 years old; ≈65.5% males); nearly two-thirds had type A AAD. Over time, the rates of hypertension increased from 77.8% to 80.4% (P=0.002), while smoking (34.1% to 30.6%, P=0.033) and atherosclerosis decreased (25.6%-16.6%; P<0.001). Across groups, the percentage of surgical repair of type A AAD increased from 89.1% to 92.5% (P<0.001) and was associated with decreased hospital mortality (from 24.1% in group 1 to 16.7% in group 3; P<0.001). There was no difference in 3-year survival (P=0.296). For type B AAD, stent graft therapy (thoracic endovascular aortic repair) was used more frequently (22.3%-35.9%; P<0.001), with a corresponding decrease in open surgery. Endovascular in-hospital mortality decreased from 9.9% to 6.2% (P=0.003). As seen with the type A AAD cohort, overall 3-year mortality for patients with type B AAD was consistent over time (P=0.084). CONCLUSIONS: Over 25 years, substantial improvements in-hospital survival were associated with a more aggressive surgical approach for patients with type A AAD. Open surgery has been partially supplanted by thoracic endovascular aortic repair for complicated type B AAD, and in-hospital mortality has decreased over the time period studied. Postdischarge survival for up to 3 years was similar over time.
RESUMO
We explored whether patient educational attainment impacted changes in cardiovascular risk factors during cardiac rehabilitation (CR). An observational study was conducted using participant data who completed phase 2 of CR from January 2011 to February 2020 at an academic medical center. The patient cohort was referred to CR after a major cardiac event or to outpatients with stable angina. Patients were excluded if they had no recorded food frequency assessment (FFA) score at CR orientation and graduation. The eligible sample of 1,307 patients were further divided: (1) low educational attainment group (<16 years formal education: high school, high school/general educational development, trade school, and associate's degree) and (2) high educational attainment group (>16 years formal education: bachelor's degree, some postgraduate, master's degree, PhD, and MD). The outcomes included measurements of the FFA, body composition, biophysical health, and psychologic distress. Most patients were male (71.2%), non-Hispanic White (82.2%), and married (73.0%). There were more patients with a high educational attainment (56.8%) than patients with a low educational attainment (43.2%). All measured cardiovascular markers improved after CR for both education level groups. The change in mean FFA score (0.163, p = 0.11) and Brief Symptom Inventory-53 global severity index score (0.422, p = 0.34) did not differ significantly. We observed an improvement in cardiovascular risk measures upon CR participation. These improvements were not limited to high educational attainment patients because we found few differences in the change of risk between the 2 groups. Future studies should continue investigating the impact of education on cardiovascular outcomes as an important social determinant of health.

Introduction: Although a recent joint society scientific statement (the American Association of Cardiovascular Pulmonary Rehabilitation, the American Heart Association, and the American College of Cardiology) suggests home-based cardiac rehab (CR) is appropriate for low- and moderate-risk patients, there are no paradigms to define such individuals with coronary heart disease. Methods: We reviewed a decade of data from all patients with coronary heart disease enrolled in a single CR center (University of Michigan) to identify the prevalence of low-risk factors, which may inform on consideration for participation in alternative models of CR. Low-risk factors included not having any of the following: metabolic syndrome, presence of implantable cardioverter defibrillator or permanent pacemaker, active smoking, prior stroke, congestive heart failure, obesity, advanced renal disease, poor exercise capacity, peripheral arterial disease, angina, or clinical depression (MI'S SCOREPAD). We report on the proportion of participants with these risk factors and the proportion with all of these low-risk factors. Results: The mean age of CR participants (n = 1984) was 63 years; 25% were women, and 82% were non-Hispanic White. The mean number of low-risk factors was 8.5, which was similar in the 2011-2012 and 2018-2019 cohorts (8.5 vs. 8.3, respectively, P = 0.08). Additionally, 9.3% of the 2011-2012 cohort and 7.6% of the 2018-2019 cohort had all 11 of the low-risk factors. Conclusion: In this observational study, we provide a first paradigm of identifying factors among coronary heart disease patients that may be considered low-risk and likely high-gain for participation in alternative models of CR. Further work is needed to track clinical outcomes in patients with these factors to determine thresholds for enrolling participants in alternative forms of CR.

OBJECTIVE: Childhood obesity remains a major public health issue. This study assessed the association between school-sourced lunches and cardiometabolic risk factors in middle-school students. METHODS: Data from health behavior surveys and physiologic screenings in a Michigan middle-school wellness program between 2005 and 2019 were used to analyze the association of school lunch consumption with cardiometabolic risk factors (overweight/obesity, non-fasting lipids/glucose, blood pressure) and dietary behaviors (fruit/vegetable consumption, intake of sugar-sweetened beverages/foods). Students were divided into three groups based on their responses to the survey item if they 1) always, 2) sometimes, or 3) never consumed school-sourced lunches. Groups were compared using descriptive statistics and chi-squared tests. RESULTS: Students consuming school-sourced lunches were more likely to have overweight or obesity, without significant differences in total, HDL, or LDL cholesterol. There was no difference in non-fasting glucose levels, blood pressure, or resting heart rate. Students consuming school sourced lunch were more likely to have increased sugary and fatty food or beverage consumption. Students consuming school sourced lunch were more likely to attend school in a low or middle socioeconomic status region. CONCLUSIONS: In this large cohort of middle-school children, consuming school-sourced lunches was associated with a greater prevalence of overweight and obesity and consumption of fatty foods and sugary beverages. School-based interventions should target methods to reduce consumption of sugary beverages and unhealthy snacks and promote consumption of fruits and vegetables, particularly among high-risk individuals.

BACKGROUND: Acute kidney injury (AKI) after repair of type A acute aortic dissection (TAAAD) has been shown to affect both short- and long-term outcomes. This study aimed to validate the impact of postoperative AKI on in-hospital and long-term outcomes in a large population of dissection patients presenting to multinational aortic centers. Additionally, we assessed risk factors for AKI including surgical details. METHODS: Patients undergoing surgical repair for TAAAD enrolled in the International Registry of Acute Aortic Dissection database were evaluated to determine the incidence and risk factors for the development of AKI. RESULTS: A total of 3307 patients were identified. There were 761 (23%) patients with postoperative AKI (AKI group) vs 2546 patients without (77%, non-AKI group). The AKI group had a higher rate of in-hospital mortality (n = 193, 25.4% vs n = 122, 4.8% in the non-AKI group, P < .001). Additional postoperative complications were also more common in the AKI group including postoperative cerebrovascular accident, reexploration for bleeding, and prolonged ventilation. Independent baseline characteristics associated with AKI included a history of hypertension, diabetes, chronic kidney disease, evidence of malperfusion on presentation, distal extent of dissection to abdominal aorta, and longer cardiopulmonary bypass time. Kaplan-Meier survival curves revealed decreased 5-year survival among the AKI group (P < .001). CONCLUSIONS: AKI occurs commonly after TAAAD repair and is associated with a significantly increased risk of operative and long-term mortality. In this large study using the International Registry of Acute Aortic Dissection database, several factors were elucidated that may affect risk of AKI.

Background: Lifestyle behaviors (LB), defined by diet and physical activity, are associated with cardiometabolic health among adults. The association of LB with cardiometabolic health among middle-school children is uncertain. Methods: An abbreviated version of the School Physical Activity and Nutrition survey was used to examine LB among students participating in a wellness program between 2004 and 2018. Students were incorporated into three groups determined by self-reported healthy LB (≥6, 4-5, ≤3 behaviors), including; ≤1 serving/day sugary foods/beverages; ≤1 serving/day fried/fatty foods; ≥1 serving/day fruits and vegetables; ≤2 hours of screen time/day; ≥1 day/week of physical education; ≥1 team sport/year; and ≥1 session/week of moderate to vigorous activity. Baseline cardiometabolic parameters [BMI, lipids, glucose, and blood pressure (BP)], resting heart rate (HR), and HR recovery were examined in association with LB groups. Results: Of 2538 children, 488 (19.2%) reported ≥6, 1219 (48.0%) reported 4-5, and 831 (32.7%) reported ≤3 LB. White or Asian race and higher socioeconomic status were associated with ≥6 LB (p < 0.001). Students performing ≤3 LB exhibited higher BMI (p < 0.001), BP (p = 0.001), resting HR (p < 0.001), and HR recovery (p < 0.001). Students performing ≥6 LB were less likely to be overweight (p < 0.001), obese (p < 0.001), or have low high-density lipoprotein (p = 0.05); however, more likely to have elevated triglycerides (p < 0.01). Conclusions: Among middle-school students, baseline BMI, BP, resting, and recovery HR were higher among children reporting fewer healthy LB. Students performing more healthy LB were less likely to be overweight or obese. Efforts to improve LB among middle-school children may be important for primordial cardiovascular prevention efforts.

OBJECTIVE: Approximately one-quarter of patients with acute type A aortic dissection (TAAD) present with concomitant malperfusion of coronary arteries, mesenteric circulation, lower extremities, kidneys, brain, and/or coma. It is generally accepted that TAAD patients who present with malperfusion experience higher mortality rates than patients without, although how specific malperfusion syndromes, alone or in combination, affect mortality is not well described. METHODS: The International Registry of Acute Aortic Dissection database was queried for patients who underwent surgical repair of TAAD. Patients were stratified according to the presence/absence of malperfusion at presentation. Multivariable logistic regression was used to evaluate in-hospital mortality according to malperfusion type. Kaplan-Meier estimates were used to estimate 30-day postoperative survival. RESULTS: Six thousand four hundred thirty-seven patients underwent surgical repair of acute TAAD, of whom 2642 (41%) had 1 or more preoperative malperfusion syndromes. Mesenteric malperfusion (adjusted odds ratio [AOR], 4.84; P < .001) was associated with the highest odds of in-hospital mortality, followed by coma (AOR, 1.88; P = .007), limb ischemia (AOR, 1.73; P = .008), and coronary malperfusion (AOR, 1.51; P = .02). Renal malperfusion (AOR, 1.37; P = .24) and neurologic deficit (AOR, 1.35; P = .28) were not associated with increased in-hospital mortality. In patients who survived to discharge, there was no difference in 1-year postdischarge survival in the malperfusion and no malperfusion cohorts (P = .36). CONCLUSIONS: Survival during the index admission after TAAD repair varies according to the presence and type of malperfusion syndromes, with mesenteric malperfusion being associated with the highest odds of in-hospital death. Not only the presence of malperfusion but rather specific malperfusion syndromes should be considered when assessing a patient's risk of undergoing TAAD repair.
RESUMO
BACKGROUND: The 30-day direct oral anticoagulant starter pack has simplified the treatment of acute venous thromboembolisms, but it is not appropriate for use in patients with other indications for anticoagulation. METHODS: A retrospective analysis of national outpatient pharmacy claims data between January 1, 2015 and December 31, 2018, was performed. Adult patients (ages >18 years) with continuous insurance enrollment at least 12 months prior to and 1 month following a direct oral anticoagulant starter pack prescription during the study period were included. The primary study outcome was the rate of inappropriate prescription of direct oral anticoagulant starter packs, defined as a prescription without a venous thromboembolism diagnosis within the prior 45 days or a prescription with a prior starter pack fill within the past 45 days. RESULTS: A total of 3711 direct oral anticoagulant starter pack prescription fills were identified, representing 3634 unique patients. The mean patient age was 62.8 years (standard deviation [SD] 15.1) and 1871 (50.4%) were females. There were 770 (20.7%) direct oral anticoagulant starter pack fills identified as potentially inappropriate. Patients prescribed inappropriate fills were likely to be older than patients with appropriate fills (64.7 years vs 62.4 years, P < 0.001). There was no significant difference in the race or geographic location between patients with inappropriate and appropriate prescriptions. CONCLUSIONS: A significant proportion of patients using direct oral anticoagulant starter packs did not have a diagnosis of acute venous thromboembolism, raising concerns about inappropriate prescribing and potential bleeding complications. Future studies are needed to identify factors associated with inappropriate direct oral anticoagulant starter pack prescription and evaluate efforts to reduce this practice.

OBJECTIVES: The diagnostic process is a vital component of safe and effective emergency department (ED) care. There are no standardized methods for identifying or reliably monitoring diagnostic errors in the ED, impeding efforts to enhance diagnostic safety. We sought to identify trigger concepts to screen ED records for diagnostic errors and describe how they can be used as a measurement strategy to identify and reduce preventable diagnostic harm. METHODS: We conducted a literature review and surveyed ED directors to compile a list of potential electronic health record (EHR) trigger (e-triggers) and non-EHR based concepts. We convened a multidisciplinary expert panel to build consensus on trigger concepts to identify and reduce preventable diagnostic harm in the ED. RESULTS: Six e-trigger and five non-EHR based concepts were selected by the expert panel. E-trigger concepts included: unscheduled ED return to ED resulting in hospital admission, death following ED visit, care escalation, high-risk conditions based on symptom-disease dyads, return visits with new diagnostic/therapeutic interventions, and change of treating service after admission. Non-EHR based signals included: cases from mortality/morbidity conferences, risk management/safety office referrals, ED medical director case referrals, patient complaints, and radiology/laboratory misreads and callbacks. The panel suggested further refinements to aid future research in defining diagnostic error epidemiology in ED settings. CONCLUSIONS: We identified a set of e-trigger concepts and non-EHR based signals that could be developed further to screen ED visits for diagnostic safety events. With additional evaluation, trigger-based methods can be used as tools to monitor and improve ED diagnostic performance.

Importance: Appendicitis may be missed during initial emergency department (ED) presentation. Objective: To compare patients with a potentially missed diagnosis of appendicitis (ie, patients with symptoms associated with appendicitis, including abdominal pain, constipation, nausea and/or vomiting, fever, and diarrhea diagnosed within 1-30 days after initial ED presentation) with patients diagnosed with appendicitis on the same day of ED presentation to identify factors associated with potentially missed appendicitis. Design, Setting, and Participants: In this cohort study, a retrospective analysis of commercially insured claims data was conducted from January 1 to December 15, 2019. Patients who presented to the ED with undifferentiated symptoms associated with appendicitis between January 1, 2010, and December 31, 2017, were identified using the Clinformatics Data Mart administrative database (Optum Insights). The study sample comprised eligible adults (aged ≥18 years) and children (aged <18 years) who had previous ED visits within 30 days of an appendicitis diagnosis. Main Outcomes and Measures: Potentially missed diagnosis of appendicitis. Adjusted odds ratios (AORs) for abdominal pain and its combinations with other symptoms associated with appendicitis were compared between patients with a same-day diagnosis of appendicitis and patients with a potentially missed diagnosis of appendicitis. Results: Of 187â¯461 patients with a diagnosis of appendicitis, a total of 123â¯711 (66%; 101â¯375 adults [81.9%] and 22â¯336 children [18.1%]) were eligible for analysis. Among adults, 51â¯923 (51.2%) were women, with a mean (SD) age of 44.3 (18.2) years; among children, 9631 (43.1%) were girls, with a mean (SD) age of 12.2 (18.2) years. The frequency of potentially missed appendicitis was 6060 of 101â¯375 adults (6.0%) and 973 of 22â¯336 children (4.4%). Patients with isolated abdominal pain (adults, AOR, 0.65; 95% CI, 0.62-0.69; P < .001; children, AOR, 0.79; 95% CI, 0.69-0.90; P < .001) or with abdominal pain and nausea and/or vomiting (adults, AOR, 0.90; 95% CI, 0.84-0.97; P = .003; children, AOR, 0.84; 95% CI, 0.71-0.98; P = .03) were less likely to have missed appendicitis. Patients with abdominal pain and constipation (adults, AOR, 1.51; 95% CI, 1.31-1.75; P < .001; children, AOR, 2.43; 95% CI, 1.86-3.17; P < .001) were more likely to have missed appendicitis. Stratified by the presence of undifferentiated symptoms, women (abdominal pain, AOR, 1.68; 95% CI, 1.58-1.78; nausea and/or vomiting, AOR, 1.68; 95% CI, 1.52-1.85; fever, AOR, 1.32; 95% CI, 1.10-1.59; diarrhea, AOR, 1.19; 95% CI, 1.01-1.40; and constipation, AOR, 1.50; 95% CI, 1.24-1.82) and girls (abdominal pain, AOR, 1.64; 95% CI, 1.43-1.88; nausea and/or vomiting, AOR, 1.74; 95% CI, 1.42-2.13; fever, AOR, 1.55; 95% CI, 1.14-2.11; diarrhea, AOR, 1.80; 95% CI, 1.19-2.74; and constipation, AOR, 1.25; 95% CI, 0.88-1.78) as well as patients with a comorbidity index of 2 or greater (adults, abdominal pain, AOR, 3.33; 95% CI, 3.09-3.60; nausea and/or vomiting, AOR, 3.66; 95% CI, 3.23-4.14; fever, AOR, 5.00; 95% CI, 3.79-6.60; diarrhea, AOR, 4.27; 95% CI, 3.39-5.38; and constipation, AOR, 4.17; 95% CI, 3.08-5.65; children, abdominal pain, AOR, 2.42; 95% CI, 1.93-3.05; nausea and/or vomiting, AOR, 2.55; 95% CI, 1.89-3.45; fever, AOR, 4.12; 95% CI, 2.71-6.25; diarrhea, AOR, 2.17; 95% CI, 1.18-3.97; and constipation, AOR, 2.19; 95% CI, 1.30-3.70) were more likely to have missed appendicitis. Adult patients who received computed tomographic scans at the initial ED visit (abdominal pain, AOR, 0.58; 95% CI, 0.52-0.65; nausea and/or vomiting, AOR, 0.63; 95% CI, 0.52-0.75; fever, AOR, 0.41; 95% CI, 0.29-0.58; diarrhea, AOR, 0.83; 95% CI, 0.58-1.20; and constipation, AOR, 0.60; 95% CI, 0.39-0.94) were less likely to have missed appendicitis. Conclusions and Relevance: Regardless of age, a missed diagnosis of appendicitis was more likely to occur in women, patients with comorbidities, and patients who experienced abdominal pain accompanied by constipation. Population-based estimates of the rates of potentially missed appendicitis reveal opportunities for improvement and identify factors that may mitigate the risk of a missed diagnosis.

PURPOSE: Assess the association of taking incidental sickness absence with health risks and health status. DESIGN: Observational. SETTING: One Midwest health care system. SUBJECTS: Individuals who were employed for 2 years (2006-2007) and had completed at least one health risk appraisal (HRA) in 2007 (N = 3790). MEASURES: Outcomes were any incidental sickness absence and absence duration in 2007 measured by an absence tracking system. Health risks and health status were estimated by HRAs. Program participation was captured using 7-year HRA data and 5-year wellness data. ANALYSIS: Multivariate, binary logistic regression for the probability of taking any absence day among the overall population as well as four demographic subgroups; proportional odds model for the probability of taking more absence days. RESULTS: Different patterns were observed in association with taking incidental sickness absence among age and gender subgroups. Among the overall population, three health risks (smoking overweight, and use of medication for relaxation) were positively associated with taking absence (at least p < .05 for all three health risks). Participation in a wellness program for more years was also associated with a less likelihood of taking absence (odds ratio, .72; p = .002). Results from the proportional odds model were consistent with results from the binary logistic regression. CONCLUSION: Sickness absence is an important productivity concern of employers. Employers may implement early interventions to focus on preventable causes. Special interventions may target absence-causing risks such as smoking behavior and excess body weight. Study limitation includes a lack of measures for psychosocial work environment.

BACKGROUND: It is estimated that 9.3% of the population in the United States have diabetes mellitus (DM), 28% of which are undiagnosed. The high prevalence of DM makes it a common comorbid condition in hospitalized patients. In recent years, government agencies and healthcare systems have increasingly focused on 30-day readmission rates to determine the complexity of their patient populations and to improve quality. Thirty-day readmission rates for hospitalized patients with DM are reported to be between 14.4 and 22.7%, much higher than the rate for all hospitalized patients (8.5-13.5%). The objectives of this study were to (1) determine the incidence and causes of 30-day readmission rates for patients with diabetes listed as either the primary reason for the index admission or with diabetes listed as a secondary diagnosis compared to those without DM and (2) evaluate the impact on readmission of two specialized inpatient DM services: the Hyperglycemic Intensive Insulin Program (HIIP) and Endocrine Consults (ENDO). METHODS: For this study, DM was defined as any ICD-9 discharge diagnosis (principal or secondary) of 250.xx. Readmissions were defined as any unscheduled inpatient admission, emergency department (ED) visit, or observation unit stay. We analyzed two separate sets of patient data. The first pilot study was a retrospective chart review of all patients with a principle or secondary admission diagnosis of diabetes admitted to any adult service within the University of Michigan Health System (UMHS) between October 1, 2013 and December 31, 2013. We then did further uncontrolled analysis of the patients with a principal admitting diagnosis of diabetes. The second larger retrospective study included all adults discharged from UMHS between October 1, 2013 and September 30, 2014 with principal or secondary discharge diagnosis of DM (ICD-9-CM: 250.xx). RESULTS: In the pilot study of 7763 admissions, the readmission rate was 26% for patients with DM and 22% for patients without DM. In patients with a primary diagnosis of DM on index admission, the most common cause for readmission was DM-related. In the larger study were 37,702 adult inpatient discharges between October 1, 2013 and September 30, 2014. Of these, 20.9% had DM listed as an encounter diagnosis. Rates for all encounters (inpatient, ED and Observation care) were 24.3% in patients with DM compared to 17.7% in those without DM (p < 0.001). The most common cause for readmission in patients with DM as a secondary diagnosis to the index admission was infection-related. During the index hospital stay, only a small proportion of patients with DM (approximately 12%) received any DM service consult. Those who received a DM consult had a higher case mix index compared to those who did not. Despite the higher acuity, there was a lower rate of ED /observation readmission in patients followed by the DM services (6.6% HIIP or ENDO vs. 9.6% no HIIP or ENDO, p = 0.0012), though no difference in the inpatient readmission rates (17.6% HIIP or ENDO vs. 17.4% no HIIP or ENDO, p = 0.89) was noted. CONCLUSIONS: Patients with both a primary or secondary diagnosis of DM have higher readmission rates. The reasons for readmission vary; patients with a principal diagnosis of DM have more DM related readmissions and those with secondary diagnosis having more infection-related readmissions. DM services were used in a small proportion of patients and may have contributed to lower DM related ED revisits. Further prospective studies evaluating the role of these services in terms of glucose management, patient education and outpatient follow up on readmission are needed to identify interventions important to reducing readmission rates.
RESUMO
PURPOSE: Academic medical centers (AMCs) have traditionally cared for the most severely ill patients. AMCs' effort to meet the challenges of managed care contracts may be nullified by adverse selection unless payment mechanisms adequately consider the health risk of the AMC's managed care population. The authors compared the disease burden between the University of Michigan Health System (UMHS) and its community competitors and assessed the effect of adding local primary care partners through strategic outsourcing on these differences in disease burden. METHOD: This is a population-based study from one managed care plan in Michigan. The study population was commercial members (n = 127, 892) enrolled in the plan for the entire 12 months of 2001. The authors derived several morbidity measures from age and sex, Adjusted Clinical Groups, and Aggregated Diagnosis Groups using administrative data. RESULTS: Compared to community groups, the UMHS consistently had a higher disease burden, while the nonacademic groups as a whole had more young members with acute conditions. After the UMHS partnered with two local primary care practice groups in their area, this AMC-local partner group had an equal or lower disease burden than the remainder of the community groups that experienced a slightly higher proportion of members with multiple medical conditions. CONCLUSIONS: The higher disease burden borne by AMCs is a complex phenomenon. Without local partners, the UMHS did experience higher disease burden, although the degree depends on the measurement of morbidity. Partnering with carefully selected local primary care groups may ameliorate the AMC's disproportionate disease burden.

The clinical impetus to develop cancer centers has been the recognition that many cancer patients require a comprehensive treatment plan coordinated across multiple specialties. Developing an effective organizational and financial structure among the multiple entities that comprise an academic cancer center has, however, been a challenge. The authors describe an effort to realize a sustainable clinical operation at the University of Michigan Comprehensive Cancer Center (UMCCC) by developing an appropriate management structure and financial model. The modified organizational structure established a clear line of administrative authority and held faculty members accountable for their effort in the UMCCC. A unified budget aligned financial incentive among all stakeholders to increase efficiency, revenue, and margin. The authors report preliminary financial evidence of the success of the new managerial structure.
