A comparison of administrative claims-based risk predictors for pediatric asthma.
This retrospective cohort study used 2013-2014 MarketScan Medicaid data to compare administrative claims-based risk predictors of emergency department (ED) visits for pediatric asthma. The cohort included were children aged 2 to 17 years. Seven risk predictors were compared for 3-month subsequent ED visits/hospitalizations: 3-month rolling asthma medication ratio (AMR), Healthcare Effectiveness Data and Information Set (HEDIS) criteria, revised HEDIS criteria, quarterly short-acting β-agonist (SABA) claims, prior ED visit, prior hospitalization, and prior ED visit or hospitalization. Sensitivity, specificity, positive and negative predictive value (PPV and NPV), and percentage of population identified as high risk were compared for each risk predictor utilization the McNemar test. Cohort total population was 214,452 children with a mean age of 7.8 years. HEDIS and revised HEDIS identified prohibitively large cohorts as high-risk (67% and 48%). For the remaining measures, the NPV range was 97% to 99%, indicating high performance at identifying patients who would not benefit from intervention using AMR and SABA count. Superior sensitivities were found for ED visit and ED/hospitalization measures compared with pharmacy claims-based measures.

Perioperative risks of sleeve gastrectomy versus roux-en-Y gastric bypass among patients with chronic kidney disease: a review of the MBSAQIP database.
The purpose of this study was to determine whether patients with chronic kidney disease experienced higher rates of perioperative complications after roux-en-Y gastric bypass (RYGB) compared to sleeve gastrectomy. The investigators concluded that among well-matched cohorts of RYGB and sleeve gastrectomy patients, incidence of primary outcomes were similar. Among secondary outcomes, only acute kidney injury was statistically-significantly higher among RYGB patients; however, the E-value for this difference was small and relatively weak confounder(s) could abrogate the statistical difference.

Oral glucocorticoids and incident treatment of diabetes mellitus, hypertension, and venous thromboembolism in children.
The purpose of this study was to quantify rates of incident treatment for diabetes mellitus, hypertension, and venous thromboembolism (VTE) associated with oral glucocorticoid exposure in children aged 1-18 years. Participants were identified using US Medicaid claims data and included more than 930,000 children diagnosed with autoimmune diseases or a nonimmune comparator condition. Findings showed strong dose-dependent relationships between current glucocorticoid exposure and all outcomes, suggesting strong relative risks, but low absolute risks, of newly-treated VTE, diabetes, and especially hypertension in children taking high-dose oral glucocorticoids.

Risk of kidney failure, death, and cardiovascular events after lower limb complications in patients with CKD.
Investigators sought to determine how interim lower limb complications modify the subsequent risk of progression to kidney failure, all-cause mortality before kidney failure, and cardiovascular events in a cohort of patients with chronic kidney disease (CKD) stages G3 to G5. Patient-level data obtained from several administrative databases from Manitoba, Canada, were analyzed. They found that interim lower limb complications were associated with an increased risk of kidney failure, all-cause mortality before kidney failure, and cardiovascular-related hospitalization. They stated that clinical trials of screening and treatment strategies for patients with CKD at risk for lower limb complications may help determine optimal strategies to manage this risk.

Metformin and risk of mortality in patients hospitalised with COVID-19: a retrospective cohort analysis.
This study examined whether metformin use by patients with diagnosed with type 2 diabetes had reduced mortality when hospitalized for COVID-19. Pharmacy claims data from UnitedHealth Group’s Clinical Discovery Claims Database was used. Patient data were included if they were aged 18 years or older; had type 2 diabetes or obesity (defined based on claims); at least 6 months of continuous enrolment in 2019; and admission to hospital for COVID-19 confirmed by PCR; manual chart review by UHG; or reported from the hospital to UHG. Metformin was not associated with significant reduction in mortality among men, but there was an association with decreased mortality in women.

Chronic physical illness burden and suicidal ideation among Dominicans in New York City.
This study used data from a community survey of 2753 Dominican adults in New York City to investigate the association between chronic illness and suicidal ideation. The investigators concluded that the association of interest did not differ significantly between younger and older adults. They suggest that screening for SI in health care practice, particularly among Dominican men with multiple chronic health conditions, may be warranted.

Diabetes mellitus is associated with higher risk of developing decompensated cirrhosis in chronic hepatitis C patients.
This study investigated the association of diabetes with risk of decompensated cirrhosis in patients with chronic hepatitis C (CHC). In a privately insured US population with CHC, the rates of decompensated cirrhosis per 1000 person-years were: 185.5 for persons with baseline cirrhosis and diabetes, 119.8 for persons with cirrhosis and no diabetes, 35.3 for persons with no cirrhosis and diabetes, and 17.1 for persons with no cirrhosis and no diabetes.

Visit-to-visit systolic blood pressure variability and microvascular complications among patients with diabetes.
This study examined the relationship between systolic blood pressure (SBP) variability and the risk of microvascular complications in a non-elderly diabetic population. Compared to individuals with the least SBP variability (Quartile 1), those with most variability (Quartile 4) had 81 percent and 19 percent higher incidence of nephropathy, retinopathy, neuropathy, and any complication, respectively, after adjusting for mean SBP, demographic and clinical factors.

Association between diagnosed diabetes and trouble seeing, National Health Interview Survey, 2011-13.
This study used nationally representative 2011–2013 data from the United States to estimate the association between diagnosed diabetes and trouble seeing. Diagnosed diabetes was associated with approximately double the odds of self-reported trouble seeing. Older age, less education, and a history of comorbid conditions were positively correlated, while male sex, being married, and having health insurance were negatively correlated with trouble seeing.

The impact of untreated obstructive sleep apnea on cardiopulmonary complications in general and vascular surgery: a cohort study.
The purpose of this study was to determine whether preoperatively untreated obstructive sleep apnea (OSA) affects postoperative outcomes. It found that compared with treated OSA, untreated OSA was independently associated with more cardiopulmonary complications (risk-adjusted rates 6.7 percent versus 4.0 percent; particularly unplanned reintubations and myocardial infarction.

Chronic hypertension in pregnancy and the risk of congenital malformations: a cohort study.
The researchers sought to examine the effect of chronic hypertension on the risk of congenital malformations in a large cohort of pregnancies in Medicaid beneficiaries. In a cohort of 878,126 pregnancies, they found that both treated and untreated maternal chronic hypertension were associated with a similar 20-30 percent increase in the risk of congenital malformations in the infant after adjusting for confounding factors as compared with normotensive controls.

Falls in people with MS--an individual data meta-analysis from studies from Australia, Sweden, United Kingdom and the United States.
The objectives of this paper are to compile fall rates across a broad range of ages and disease severity and to definitively assess the extent to which multiple sclerosis (MS)-associated and demographic factors influence fall rates. It found that persons with MS are at high risk of falls and there are important associations between falls and MS-associated disability, gender and age.
