Observational Study
Development of risk models for major adverse chronic renal outcomes among patients with type 2 diabetes mellitus using insurance claims: a retrospective observational study.
Objective: To develop and validate models allowing the prediction of major adverse chronic renal outcomes (MACRO) in patients with type 2 diabetes mellitus (T2DM) using insurance claims data. Methods: The Optum Integrated Real World Evidence Electronic Health Records and Claims de-identified database (10/01/2006-09/30/2016) was used to identify T2DM patients ≥50 years old. Risk factors were assessed over a 12-month baseline period, and MACRO were subsequently assessed until the end of data availability, continuous enrollment, or death. ⋯ A substantial proportion (e.g. 88.7% for moderate-to-severe DKD) of patients predicted to be at high-risk of MACRO did not have diabetic nephropathy, proteinuria, or CKD at baseline. Conclusions: The models developed using insurance claims data could reliably predict the risk of MACRO in patients with T2DM and enabled patients at higher-risk of DKD to be identified in the absence of baseline diabetic nephropathy, CKD, or proteinuria. These models could help establish strategies to reduce the risk of MACRO in T2DM patients.

Objective: To investigate the evolution of opioid-related mortality and potential years of life lost in Spanish general population from 2008 to 2017. To evaluate the differences between Spain and the US. Methods: A descriptive study using retrospective annual data from 2008 to 2017 in Spanish and US general population. ⋯ The standardized rates per 105 inhabitants across the years were between 1.19 and 1.62 in Spain and between 11.17 and 20.68 in the US population. Conclusions: An opioid overuse crisis does not seem a likely scenario in Spain. However, it is a social problem that requires special health surveillance, particularly in middle-aged men and women over 65.

Objectives: To assess characteristics and healthcare costs associated with pharmacologically treated episodes of treatment-resistant depression (TRD) in patients with major depressive disorder (MDD). Methods: Patients aged ≥18 years with continuous health plan enrollment for ≥12 months before and after a newly observed MDD diagnosis (observed between 1 January 2010 and 31 December 2015) were included in this retrospective claims-based analysis. A pharmacologically treated episode was defined as beginning at the date of the first MDD diagnosis and ending when a gap of 180 days occurred between MDD diagnoses, or when a gap of 180 days occurred following the end of the antidepressant (AD)/antipsychotic (AP) drug supply. ⋯ Conclusions: Results show TRD episodes are longer and costlier than non-TRD MDD episodes, and that higher costs are driven by episode duration. Longer episodes imply protracted suffering for patients with TRD and increased burden on caregivers. Effective intervention to shorten TRD episodes may lessen disease burden and reduce costs.

Objective: To evaluate the validity of diagnosis codes for identifying obesity and morbid obesity among newly treated nonvalvular atrial fibrillation (NVAF) patients. Methods: An integrated electronic medical record (EMR) and claims database (1 January 2013-31 March 2018) was used. Adult patients with ≥1 claim for an oral anticoagulant (OAC) from 1 January 2014-30 September 2017 were identified (index date). ⋯ Conclusion: Among newly treated NVAF patients, obesity diagnosis codes had high PPV, high specificity and modest sensitivity. Morbid obesity diagnosis codes also had high specificity, but modest PPV and sensitivity. These findings have implications for case selection and control for obesity as a confounder in studies using a claims database.

Objective: The purpose of this study was to examine surgical and survival outcomes in the elderly (65-79 years of age) and the very elderly (≥80 years of age) who received surgery for gastric cancer. Methods: This study retrospectively reviewed the records of patients ≥65 years old who received a gastrectomy for gastric adenocarcinoma. Demographic, clinical, and pathological data were extracted from the medical records. ⋯ Patients ≥80 years had a higher incidence of pulmonary complications (24% vs 4.7%, p = .03), but there was no significant difference in in-hospital mortality. The ≥80 years group had a higher overall survival, but the difference between the groups was not statistically significant (42.9% and 34.9%, p = .224). Conclusions: Curative intent resection, gastrectomy with D1+/D2 lymph node dissection is a viable option for elders ≥80 years old with gastric carcinoma.
