RESUMO
Importance: Little is known about incidence of, risk factors for, and harms associated with inappropriate diagnosis of community-acquired pneumonia (CAP). Objective: To characterize inappropriate diagnosis of CAP in hospitalized patients. Design, Setting, and Participants: This prospective cohort study, including medical record review and patient telephone calls, took place across 48 Michigan hospitals. Trained abstractors retrospectively assessed hospitalized patients treated for CAP between July 1, 2017, and March 31, 2020. Patients were eligible for inclusion if they were adults admitted to general care with a discharge diagnostic code of pneumonia who received antibiotics on day 1 or 2 of hospitalization. Data were analyzed from February to December 2023. Main Outcomes and Measures: Inappropriate diagnosis of CAP was defined using a National Quality Forum-endorsed metric as CAP-directed antibiotic therapy in patients with fewer than 2 signs or symptoms of CAP or negative chest imaging. Risk factors for inappropriate diagnosis were assessed and, for those inappropriately diagnosed, 30-day composite outcomes (mortality, readmission, emergency department visit, Clostridioides difficile infection, and antibiotic-associated adverse events) were documented and stratified by full course (>3 days) vs brief (≤3 days) antibiotic treatment using generalized estimating equation models adjusting for confounders and propensity for treatment. Results: Of the 17â¯290 hospitalized patients treated for CAP, 2079 (12.0%) met criteria for inappropriate diagnosis (median [IQR] age, 71.8 [60.1-82.8] years; 1045 [50.3%] female), of whom 1821 (87.6%) received full antibiotic courses. Compared with patients with CAP, patients inappropriately diagnosed were older (adjusted odds ratio [AOR], 1.08; 95% CI, 1.05-1.11 per decade) and more likely to have dementia (AOR, 1.79; 95% CI, 1.55-2.08) or altered mental status on presentation (AOR, 1.75; 95% CI, 1.39-2.19). Among those inappropriately diagnosed, 30-day composite outcomes for full vs brief treatment did not differ (25.8% vs 25.6%; AOR, 0.98; 95% CI, 0.79-1.23). Full vs brief duration of antibiotic treatment among patients was associated with antibiotic-associated adverse events (31 of 1821 [2.1%] vs 1 of 258 [0.4%]; P = .03). Conclusions and Relevance: In this cohort study, inappropriate diagnosis of CAP among hospitalized adults was common, particularly among older adults, those with dementia, and those presenting with altered mental status. Full-course antibiotic treatment of those inappropriately diagnosed with CAP may be harmful.

BACKGROUND: Smartphone applications and wearable devices are promising mobile health interventions for hypertension self-management. However, most mobile health interventions fail to use contextual data, potentially diminishing their impact. The myBPmyLife Study is a just-in-time adaptive intervention designed to promote personalized self-management for patients with hypertension. METHODS AND RESULTS: The study is a 6-month prospective, randomized-controlled, remotely administered trial. Participants were recruited from the University of Michigan Health in Ann Arbor, Michigan or the Hamilton Community Health Network, a federally qualified health center network in Flint, Michigan. Participants were randomized to a mobile application with a just-in-time adaptive intervention promoting physical activity and lower-sodium food choices as well as weekly goal setting or usual care. The mobile study application encourages goal attainment through a central visualization displaying participants' progress toward their goals for physical activity and lower-sodium food choices. Participants in both groups are followed for up for 6 months with a primary end point of change in systolic blood pressure. Exploratory analyses will examine the impact of notifications on step count and self-reported lower-sodium food choices. The study launched on December 9, 2021, with 484 participants enrolled as of March 31, 2023. Enrollment of participants was completed on July 3, 2023. After 6 months of follow-up, it is expected that results will be available in the spring of 2024. CONCLUSIONS: The myBPmyLife study is an innovative mobile health trial designed to evaluate the effects of a just-in-time adaptive intervention focused on improving physical activity and dietary sodium intake on blood pressure in diverse patients with hypertension.

Importance: Hospitalized patients with asymptomatic bacteriuria (ASB) often receive unnecessary antibiotic treatment, which increases antibiotic resistance and adverse events. Objective: To determine whether diagnostic stewardship (avoiding unnecessary urine cultures) or antibiotic stewardship (reducing unnecessary antibiotic treatment after an unnecessary culture) is associated with better outcomes in reducing antibiotic use for ASB. Design, Setting, and Participants: This 3-year, prospective quality improvement study included hospitalized general care medicine patients with a positive urine culture among 46 hospitals participating in a collaborative quality initiative, the Michigan Hospital Medicine Safety Consortium. Data were collected from July 1, 2017, through March 31, 2020, and analyzed from February to October 2022. Exposure: Participation in the Michigan Hospital Medicine Safety Consortium with antibiotic and diagnostic stewardship strategies at hospital discretion. Main Outcomes and Measures: Overall improvement in ASB-related antibiotic use was estimated as change in percentage of patients treated with antibiotics who had ASB. Effect of diagnostic stewardship was estimated as change in percentage of patients with a positive urine culture who had ASB. Effect of antibiotic stewardship was estimated as change in percentage of patients with ASB who received antibiotics and antibiotic duration. Results: Of the 14â¯572 patients with a positive urine culture included in the study (median [IQR] age, 75.8 [64.2-85.1] years; 70.5% female); 28.4% (n = 4134) had ASB, of whom 76.8% (n = 3175) received antibiotics. Over the study period, the percentage of patients treated with antibiotics who had ASB (overall ASB-related antibiotic use) declined from 29.1% (95% CI, 26.2%-32.2%) to 17.1% (95% CI, 14.3%-20.2%) (adjusted odds ratio [aOR], 0.94 per quarter; 95% CI, 0.92-0.96). The percentage of patients with a positive urine culture who had ASB (diagnostic stewardship metric) declined from 34.1% (95% CI, 31.0%-37.3%) to 22.5% (95% CI, 19.7%-25.6%) (aOR, 0.95 per quarter; 95% CI, 0.93-0.97). The percentage of patients with ASB who received antibiotics (antibiotic stewardship metric) remained stable, from 82.0% (95% CI, 77.7%-85.6%) to 76.3% (95% CI, 68.5%-82.6%) (aOR, 0.97 per quarter; 95% CI, 0.94-1.01), as did adjusted mean antibiotic duration, from 6.38 (95% CI, 6.00-6.78) days to 5.93 (95% CI, 5.54-6.35) days (adjusted incidence rate ratio, 0.99 per quarter; 95% CI, 0.99-1.00). Conclusions and Relevance: This quality improvement study showed that over 3 years, ASB-related antibiotic use decreased and was associated with a decline in unnecessary urine cultures. Hospitals should prioritize reducing unnecessary urine cultures (ie, diagnostic stewardship) to reduce antibiotic treatment related to ASB.

Rationale: Little is known about the safety of infusing vasopressors through a midline catheter. Objectives: To evaluate safety outcomes after vasopressor administration through a midline. Methods: We conducted a cohort study of adults admitted to 39 hospitals in Michigan (December 2017-March 2022) who received vasopressors while either a midline or peripherally inserted central catheter (PICC) was in place. Patients receiving vasopressors through a midline were compared with those receiving vasopressors through a PICC and, separately, to those with midlines in place but who received vasopressors through a different catheter. We used descriptive statistics to characterize and compare cohort characteristics. Multivariable mixed effects logistic regression models were fit to determine the association between vasopressor administration through a midline with outcomes, primarily catheter-related complications (bloodstream infection, superficial thrombophlebitis, exit site infection, or catheter occlusion). Results: Our cohort included 287 patients with midlines through which vasopressors were administered, 1,660 with PICCs through which vasopressors were administered, and 884 patients with midlines who received vasopressors through a separate catheter. Age (median [interquartile range]: 68.7 [58.6-75.7], 66.6 [57.1-75.0], and 67.6 [58.7-75.8] yr) and gender (percentage female: 50.5%, 47.3%, and 43.8%) were similar in all groups. The frequency of catheter-related complications was lower in patients with midlines used for vasopressors than PICCs used for vasopressors (5.2% vs. 13.4%; P < 0.001) but similar to midlines with vasopressor administration through a different device (5.2% vs. 6.3%; P = 0.49). After adjustment, administration of vasopressors through a midline was not associated with catheter-related complications compared with PICCs with vasopressors (adjusted odds ratios [aOR], 0.65 [95% confidence interval, 0.31-1.33]; P = 0.23) or midlines with vasopressors elsewhere (aOR, 0.85 [0.46-1.58]; P = 0.59). Midlines used for vasopressors were associated with greater risk of systemic thromboembolism (vs. PICCs with vasopressors: aOR, 2.69 [1.31-5.49]; P = 0.008; vs. midlines with vasopressors elsewhere: aOR, 2.42 [1.29-4.54]; P = 0.008) but not thromboses restricted to the ipsilateral upper extremity (vs. PICCs with vasopressors: aOR, 2.35 [0.83-6.63]; P = 0.10; model did not converge for vs. midlines with vasopressors elsewhere). Conclusions: We found no significant association of vasopressor administration through a midline with catheter-related complications. However, we identified increased odds of systemic (but not ipsilateral upper extremity) venous thromboembolism warranting further evaluation.

Background: Trends in temporary mechanical circulatory support (tMCS) use with associated outcomes and cost in cardiogenic shock secondary to decompensated chronic heart failure (HF-CS) remains poorly understood. We describe trends in tMCS use, associated outcomes, and cost in HF-CS. Methods: We included adults enrolled in a national insurance claims dataset with HF-CS who received intra-aortic balloon pump (IABP), Impella, or extracorporeal membrane oxygenation (ECMO) without acute coronary syndrome, or postcardiotomy shock. We identified predictors of device use, associated outcomes, and inflation-adjusted costs. Results: We studied 2722 HF-CS patients receiving tMCS: 1799 (66%) male, 1771 (65%) White, and 1836 (67%) with ischemic cardiomyopathy. Rate of tMCS use increased from 2010-2019. Impella use showed the largest increase (Δ+344%), followed by ECMO (Δ+112%). Patients receiving ECMO had a higher comorbidity burden, and patients receiving IABP were more likely to have valvular heart disease. Compared with IABP, 30-day mortality rate was no different for Impella (adjusted odds ratio, 1.24; 95% CI, 0.93-1.66) but was higher with ECMO (adjusted odds ratio, 3.08; 95% CI, 2.22-4.27). Adjusted hospitalization cost was highest for ECMO (median, $191,079 [IQR, $165,760-$239,373]), followed by Impella (median, $142,518 [IQR, $126,845-$179,938]), and IABP (median, $132,060 [IQR, $113,794-$160,244]). We observed a linear association between price standardized cost-quartile and complications, but not for 30-day mortality. Conclusions: The use of Impella and ECMO is increasing with an associated cost increase. The use of ECMO coincided with higher 30-day mortality compared with IABP in HF-CS. These findings likely reflect increasing disease severity and evolving practice patterns rather than causation.
RESUMO
Background Current guidelines recommend use of sacubitril-valsartan in patients with heart failure with reduced ejection fraction (HFrEF). Early data suggested low uptake of sacubitril-valsartan, but contemporary data on real-world use and their associated cost are limited. Methods and Results This was a retrospective study of individuals enrolled in Optum Clinformatics, a national insurance claims data set from 2016 to 2018. We included all adult patients with HFrEF with 2 outpatient encounters or 1 inpatient encounter with an International Classification of Diseases, Tenth Revision (ICD-10), diagnosis of HFrEF and 6 months of continuous enrollment, also receiving ß-blockers and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers within 6 months of HFrEF diagnosis. We included 70 245 patients with HFrEF, and 5217 patients (7.4%) received sacubitril-valsartan prescriptions. Patients receiving care through a cardiologist compared with a primary care physician alone were more likely to receive sacubitril-valsartan (odds ratio, 1.61 [95% CI, 1.52-1.71]). Monthly out-of-pocket (OOP) cost for sacubitril-valsartan, compared with angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, was higher for both commercially insured patients (mean, $69 versus $6.74) and Medicare Advantage (mean, $62 versus $2.52). For patients with commercial insurance, OOP cost was lower in 2016 than in 2018. For patients with Medicare Advantage, there was a significant geographic variation in the OOP costs across the country, ranging from $31 to $68 per month across different regions, holding all other patient-related factors constant. Conclusions Sacubitril-valsartan use was infrequent among patients with HFrEF. Patients receiving care with a cardiologist were more likely to receive sacubitril-valsartan. OOP costs remain high, potentially limiting use. Significant geographic variation in OOP costs, unexplained by patient factors, was noted.

BACKGROUND: Each year there are 800,000 myocardial infarctions in the United States. There is an increased risk of hospitalization for acute myocardial infarction (AMI) for those with periodontal disease. Yet, there is a paucity of knowledge about downstream care of AMI and how this varies with periodontal care status. The authors' aim was to examine the association between periodontal care and AMI hospitalization and 30 days after acute care. METHODS: Using the MarketScan database, the authors conducted a retrospective cohort study among patients with both dental insurance and medical insurance in 2016 through 2018 who were hospitalized for AMI in 2017. RESULTS: There were 2,370 patients who had dental and medical coverage for 2016 through 2018 and received oral health care in 2016 through 2017 and had an AMI hospitalization in 2017. Forty-seven percent received regular or other oral health care, 7% received active periodontal care, and 10% received controlled periodontal care. More than one-third of patients (36%) did not have oral health care before the AMI hospitalization. After adjusting for patient characteristics, we found that patients in the controlled periodontal care group were significantly more likely to have visits during the 30 days after AMI hospitalization (adjusted odds ratio, 1.63; 95% CI, 1.07 to 2.47; P = .02). CONCLUSIONS: We found that periodontal care was associated with more after AMI visits. This suggests that there is a benefit to incorporating oral health care and medical care to improve AMI outcomes. PRACTICAL IMPLICATIONS: Needing periodontal care is associated with more favorable outcomes related to AMI hospitalization. Early intervention to ensure stable periodontal health in patients with risk factors for AMI could reduce downstream hospital resource use.

Urinary tract infection (UTI) and community-acquired pneumonia (CAP) are the most common infections treated in hospitals. UTI and CAP are also commonly overdiagnosed, resulting in unnecessary antibiotic use and diagnostic delays. While much is known individually about overdiagnosis of UTI and CAP, it is not known whether hospitals with higher overdiagnosis of one also have higher overdiagnosis of the other. Correlation of overdiagnosis of these two conditions may indicate underlying hospital-level contributors, which in turn may represent targets for intervention. To evaluate the association of overdiagnosis of UTI and CAP, we first determined the proportion of hospitalised patients treated for CAP or UTI at 46 hospitals in Michigan who were overdiagnosed according to national guideline definitions. Then, we used Pearson's correlation coefficient to compare hospital proportions of overdiagnosis of CAP and UTI. Finally, we assessed for 'diagnostic momentum' (ie, accepting a previous diagnosis without sufficient scepticism) by determining how often overdiagnosed patients remained on antibiotics on day 3 of hospitalisation. We included 14 085 patients treated for CAP (11.4% were overdiagnosed) and 10 398 patients treated for UTI (27.8% were overdiagnosed) across 46 hospitals. Within hospitals, the proportion of patients overdiagnosed with UTI was moderately correlated with the proportion of patients overdiagnosed with CAP (r=0.53, p<0.001). Over 80% (81.8% (n=952/1164) of UTI; 89.9% (n=796/885) of CAP) of overdiagnosed patients started on antibiotics by an emergency medicine clinician remained on antibiotics on day 3 of hospitalisation. In conclusion, we found overdiagnosis of UTI and CAP to be correlated at the hospital level. Reducing overdiagnosis of these two common infections may benefit from systematic interventions.

BACKGROUND: Venous thromboembolism is a leading cause of death in patients with cancer. Inferior vena cava filters are utilized to mitigate the risk of pulmonary embolism for patients who have contraindication to, or failure of, anticoagulation. METHODS: We reviewed an insurance claims database to identify adults receiving cancer-directed therapy and had a new diagnosis of venous thromboembolism. We then evaluated clinical and sociodemographic characteristics in patients with and without filter placement and retrieval. RESULTS: There were 25,788 patients (mean [SD] age: 68.3 [12.7] years) who met the study inclusion criteria, with 2111 individuals (8.2%) undergoing filter placement. Filter placement was associated with the type of thrombosis, malignancy, recent surgery, comorbidities, and income. A total of 137 patients (6.5%) newly started anticoagulation within 3 days of filter placement, and 612 (29%) patients received anticoagulation within 30 days after filter placement. Despite this, only 159 (7.5%) patients had their filters retrieved during the study period. Patients with income of $75-99K (odds ratio 2.13, P = .012) or above $100K (odds ratio 1.8, P = .038) were more likely to have filter retrieval compared with those with income <$50K. Filter retrieval was also more likely in younger patients and those with fewer comorbidities or without central nervous system or lung malignancies. CONCLUSIONS: Inferior vena cava filter placement and retrieval are associated with several sociodemographic factors. Filter retrieval rates are low despite re-initiation of anticoagulation in many patients. Efforts are needed to address disparities in filter use and improve retrieval rates.

PURPOSE: Persons with disabilities often experience uncoordinated health care, with repeated out-of-pocket copays. One purpose of the Patient Protection and Affordable Care Act (ACA) was to create zero copays for preventive health care including an annual wellness visit (AWV). The purpose of this study was to document the use of AWVs by persons with physical disabilities during the ACA rollout. METHODS: An administrative claims database, including both Medicare Advantage (MA) and commercial (COM) payers from 2008 to 2016, was used to identify unique wellness visits for adults with physical disabilities. We used interrupted time series analysis to compare AWV use by insurance type, sex, disability type, and race over time. RESULTS: The proportion of zero copays provided a timeline of ACA implementation categorized as pre-ACA, ACA-implementation, and post-ACA periods. By 2016, AWV use maximized at 47.6% (95% CI, 44.7%-50.8%) among COM-insured White women with congenital disabilities. By 2016, the lowest AWV use reached one-half the maximum, at 21.6% (95% CI, 18.4%-25.2%) among COM-insured Hispanic men with acquired disabilities. MA-insured Black and Hispanic men with acquired disabilities reached similarly low levels of AWV use. CONCLUSION: The ACA mandated zero copays, thereby allowing persons with physical disabilities the option for preventive health care without cost. Insurance type and sex significantly influenced AWV use, followed by disability type and race. Gaps in AWV use were exposed by insurance type, sex, disability, and race for persons with disabilities. Gaps in AWV use were also exposed between the general population and persons with disabilities.Annals "Online First" article.

AIM: To validate the Whitney Comorbidity Index (WCI), which was recently developed to monitor disease status for adults with cerebral palsy (CP), and to identify WCI scores associated with an increased mortality risk using a representative sample of adults with CP. METHOD: Data from 2016 to 2018 were used from a random 20% sample from the fee-for-service Medicare database for this retrospective cohort study. The WCI was examined as unweighted (WCIunw ) and weighted (WCIw ) among adults at least 18 years old with CP. Cox regression models were developed with mortality as the outcome after adjusting for demographics. A concordance statistic (C-statistic) of at least 0.70 was considered as showing sufficient validity. The hazard ratio of mortality for each WCI score was estimated. Secondary analyses were performed for subgroups with co-occurring epilepsy and/or intellectual disabilities. RESULTS: For the entire group (n=16 728) and subgroups, the WCI showed sufficient validity (C-statistic 0.73-0.81). For the entire group, the mortality rate was elevated for a score of 1 compared with 0 from the WCIunw (hazard ratio 3.06; 95% confidence interval [CI] 1.52-6.17) and WCIw (hazard ratio 4.08; 95% CI 1.69-9.85), and became larger with each WCI score. Results were similar for the subgroups. INTERPRETATION: The WCI is a valid marker for health/disease status for adults with CP. Several WCI score thresholds were identified to assist in clinical decision making for preventive medicine and intervention implementation. What this paper adds The Whitney Comorbidity Index (WCI) is valid among 16 728 adults with CP. The WCI is valid for those with co-occurring epilepsy and/or intellectual disabilities. Thresholds of the WCI score were identified to assist clinical decision making.

Cancer associated thrombosis (CAT) is a leading cause of death among patients with cancer. It is not clear if non-clinical factors are associated with anticoagulation receipt. We conducted a retrospective cohort study of Optum's de-identified Clinformatics® Database of adults with cancer diagnosed between 2009 and 2016 who developed CAT, treated with an outpatient anticoagulant (warfarin, low molecular weight heparin (LMWH), or a direct oral anticoagulant (DOAC)). Of 12,622 patients, three months after an episode of CAT, 1,485 (12%) were on LMWH, 1,546 (12%) on DOACs, and 9,591 (76%) were on warfarin. When controlling for other factors, anticoagulant use was significantly associated with socioeconomic factors, region, co-morbidities, type of thrombosis, and cancer subtype. Patients with a bachelor's degree or greater level of education were less likely to receive warfarin (OR: 0.77; 95% CI: [0.59, 0.99]; p < 0.046) or DOACs (OR: 0.67; 95% CI: [0.55, 0.82]; p < 0.001) compared to LMWH. Patients with higher income levels were more likely to receive LMWH or DOACs compared to warfarin, while patients across all income levels were equally likely to receive LMWH or DOACs. Non-clinical factors including income, education, and region, are associated with anticoagulation receipt three months after an episode of CAT. Sociodemographic factors may result in some patients receiving suboptimal care and contribute to non-guideline concordant care for CAT.

Essentials It is not clear if patients are less adherent to low molecular weight heparin (LMWH) compared to direct oral anticoagulants (DOACs) for cancer-associated thrombosis (CAT). We evaluated medication adherence among two propensity-matched groups of patients with CAT by comparing the proportion of days covered (PDC). Median treatment persistence on DOACs was more than 80 days longer than LMWH. Medication adherence was high (~95%) and was similar with LMWH compared to DOACs. ABSTRACT: Background Low molecular weight heparin (LMWH) and direct oral anticoagulants (DOACs) are used to treat cancer-associated thrombosis (CAT). It is not clear if patients are less adherent to LMWH compared to DOACs. Objectives To compare medication persistence and adherence between LMWH and DOACs. Patients/Methods We analyzed Optum's de-identified Clinformatics® Data Mart Database of privately insured adults with cancer diagnosed between January 2009 and October 2015 who were undergoing chemotherapy, immunotherapy, targeted or hormonal therapies; developed CAT; and were treated with an outpatient anticoagulant. The proportion of days covered (PDC) was calculated from the date of anticoagulant prescription until the anticoagulant was switched, stopped, or the study end. Medication adherence was defined as PDC ≥ 80%, ≥95%, and by comparing the mean PDC. Results Two propensity-matched groups of 1128 patients were identified. Patient persistence was higher with DOACs compared to LMWH (median 116 days versus 34 days). With adherence defined as PDC ≥ 80%, we found no significant difference (95.6% versus 94.6% adherence with DOACs versus LMWH, P = .33). The mean difference of PDC between the two groups was also similar. With medication adherence defined as PDC ≥ 95%, adherence was evident in 73% of DOAC users and 81% of patients on LMWH (P < .001). Prescription copayments were higher on average for LMWH compared to DOACs (mean $153.61 versus 40.67; standard deviation $306.74 versus $33.11). Conclusion Patients remain on DOACs longer than LMWH, but medication adherence is similar with LMWH.

BACKGROUND: Patients who have intellectual/developmental disabilities (IDDs) develop atherosclerotic cardiovascular disease (ASCVD) or heart failure (HF) at rates similar to or higher than the general population. They also face disparities accessing and using health care services. OBJECTIVE: To determine if disparities exist in the use of guideline-based pharmacotherapy (GBP) for ASCVD or HF for adults with IDD. METHODS: Using the 2014 Clinformatics Data Mart Database, adults with ASCVD or HF were divided into IDD or non-IDD groups. Patients with contraindications for GBP medications were excluded. Use of GBP between IDD and non-IDD groups was examined. Subgroup analysis included comparisons between IDD groups. RESULTS: For HF, 1011 patients with IDD and 236,638 non-IDD patients were identified. For ASCVD, 2190 IDD and 790,343 non-IDD patients were identified. We found that 47.9%, 35.8%, and 13.1% of IDD and 58.7%, 48.4%, and 18.9% of non-IDD patients had pharmacy claims for statins (P < 0.001), ß-blockers (P < 0.001), or antiplatelet therapy (P < 0.001), respectively. For HF, 46.8% and 50.3% of IDD and 59.8% and 55.4% of non-IDD patients had pharmacy claims for ß-blockers (P < 0.001) and angiotensin-converting enzyme (ACE) inhibitors or angiotensin-receptor blockers (ARBs; P = 0.003), respectively. In all but one multivariate regression models patients with IDD were less likely to use GBP than patients in the non-IDD group. Subgroup analysis revealed that patients who had Down syndrome had lower GBP use in 4 of the 5 measures. CONCLUSION AND RELEVANCE: Disparities exist in the use of GBP for patients with IDD with ASCVD or HF. Patients who have an IDD should be examined by clinicians to ensure appropriate access to and use of GBP.

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.

OBJECTIVE: To examine the association between hearing aids (HAs) and time to diagnosis of Alzheimer disease (AD) or dementia, anxiety or depression, and injurious falls among adults, aged 66 years and older, within 3 years of hearing loss (HL) diagnosis. DESIGN: Retrospective cohort study. SETTING: We used 2008 to 2016 national longitudinal claims data (based on office visit, inpatient, or outpatient healthcare encounters) from a large private payer. We used Kaplan-Meier curves to examine unadjusted disease-free survival and crude and adjusted Cox regression models to examine associations between HAs and time to diagnosis of three age-related/HL-associated conditions within 3 years of HL diagnosis. All models were adjusted for age, sex, race/ethnicity, census divisions, and prior diagnosis of cardiovascular conditions, hypertension, hypercholesterolemia, obesity, and diabetes. PARTICIPANTS: The participants included 114 862 adults, aged 66 years and older, diagnosed with HL. MEASUREMENT: Diagnosis of (1) AD or dementia; (2) depression or anxiety; and (3) injurious falls. INTERVENTION: Use of HAs. RESULTS: Large sex and racial/ethnic differences exist in HA use. Approximately 11.3% of women vs 13.3% of men used HAs (95% confidence interval [CI] difference = -0.024 to -0.016). Approximately 13.6% of whites (95% CI = 0.13-0.14) vs 9.8% of blacks (95% CI = 0.09-0.11) and 6.5% of Hispanics (95% CI = 0.06-0.07) used HAs. The risk-adjusted hazard ratios of being diagnosed with AD/dementia, anxiety/depression, and injurious falls within 3 years after HL diagnosis, for those who used HAs vs those who did not, were 0.82 (95% CI = 0.76-0.89), 0.89 (95% CI = 0.86-0.93), and 0.87 (95% CI = 0.80-0.95), respectively. CONCLUSIONS: Use of HAs is associated with delayed diagnosis of AD, dementia, depression, anxiety, and injurious falls among older adults with HL. Although we have shown an association between use of HAs and reduced risk of physical and mental decline, randomized trials are needed to determine whether, and to what extent, the relationship is causal.

We evaluated whether rotavirus vaccination is associated with the incidence of type 1 diabetes among children. We designed a cohort study of 1,474,535 infants in the United States from 2001-2017, using data from a nationwide health insurer. There was a 33% reduction in the risk of type 1 diabetes with completion of the rotavirus vaccine series compared to the unvaccinated (95% CI: 17%, 46%). Completion of the pentavalent vaccine series was associated with 37% lower risk of type 1 diabetes (95% CI: 22%, 50%). Partial vaccination (incompletion of the series) was not associated with the incidence of type 1 diabetes. There was a 31% reduction in hospitalizations in the 60-day period after vaccination (95% CI: 27%, 35%) compared to unvaccinated children. Overall, there was a 3.4% decrease in incidence annually in children ages 0-4 in the United States from 2006-2017 which coincides with the vaccine introduction in 2006. We conclude that rotavirus vaccination is associated with a reduced incidence of type 1 diabetes. Rotavirus vaccination may be the first practical measure that could play a role in the prevention of this disease.

OBJECTIVE: There have been few studies regarding the duration of insulin prescriptions and patient outcomes. This study evaluated whether A1C varied with the duration of insulin prescription in patients with type 1 diabetes. METHODS: We conducted a longitudinal investigation (from 2001 to 2015) within a nationwide private health insurer. A cohort study was first used to compare A1C after 30-day only, 90-day only, and a combination (30-day and 90-day) of insulin prescriptions. Second, a self-controlled case series was used to compare A1C levels after 30-day versus 90-day prescriptions for the same person. RESULTS: In the cohort study, there were 16,725 eligible patients. Mean A1C was 8.33% for patients with 30-day prescriptions compared to 7.69% for those with 90-day prescriptions and 8.05% for those who had a combination of 30- and 90-day prescriptions (P <0.001). Results were similar when stratified by age and sex. Mean A1C was 7.58% when all prescriptions were mailed versus 8.21% when they were not. In the self-controlled case series, there were 1,712 patients who switched between 30- and 90-day prescriptions. Mean A1C was 7.87% after 30-day prescriptions and 7.69% after 90-day prescriptions (P <0.001). Results were similar when stratified by sex. For this within-person comparison, the results remained significant for those ≥20 years of age (n = 1,536, P <0.001), but not for youth (n = 176, P = 0.972). CONCLUSION: There was a statistically significant but clinically modest decrease in A1C with 90-day versus 30-day insulin prescriptions in adults. A mailed 90-day insulin prescription may be a reasonable choice for adults with type 1 diabetes.
RESUMO
OBJECTIVE: To determine the influence of delivery hospital on the rate of vaginal birth after cesarean (VBAC). STUDY DESIGN: This retrospective cohort study used claims data from Blue Cross and Blue Shield of Michigan. Women with a prior cesarean and a singleton livebirth between 2012 and 2016 were included. We calculated the hospital-specific risk-standardized VBAC rates and median odds ratio as a measure of variation. RESULT: Hospital-level adjusted rates varied nearly tenfold (3.7%-35.5%). Compared to the lowest volume hospitals (1st quartile), the likelihood of VBAC increased for those in the 2nd (adjusted OR 2.75 [95% CI 1.23-6.17]), 3rd (adjusted OR 3.73 [95% CI 1.59-8.75]), and 4th quartiles (adjusted OR 2.9 [95% CI 1.11-7.72]). The median OR suggested significant variation by hospital after adjustment. CONCLUSION: The delivery hospital itself explains a large amount of the variation in rates of VBAC after adjustment for patient and hospital characteristics.
