Diabetes diagnosis from administrative claims and estimation of the true prevalence of diabetes among 4.2 million individuals of the Veneto region (North East Italy)

Background and aimsDiabetes can often remain undiagnosed or unregistered in administrative databases long after its onset, even when laboratory test results meet diagnostic criteria. In the present work, we analyse healthcare data of the Veneto Region, North East Italy, with the aims of: (i) developing an algorithm for the identification of diabetes from administrative claims (4,236,007 citizens), (ii) assessing its reliability by comparing its performance with the gold standard clinical diagnosis from a clinical database (7525 patients), (iii) combining the algorithm and the laboratory data of the regional Health Information Exchange (rHIE) system (543,520 subjects) to identify undiagnosed diabetes, and (iv) providing a credible estimate of the true prevalence of diabetes in Veneto.Methods and resultsThe proposed algorithm for the identification of diabetes was fed by administrative data related to drug dispensations, outpatient visits, and hospitalisations. Evaluated against a clinical database, the algorithm achieved 95.7% sensitivity, 87.9% specificity, and 97.6% precision. To identify possible cases of undiagnosed diabetes, we applied standard diagnostic criteria to the laboratory test results of the subjects who, according to the algorithm, had no diabetes-related claims. Using a simplified probabilistic model, we corrected our claims-based estimate of known diabetes (6.17% prevalence; 261,303 cases) to account for undiagnosed cases, yielding an estimated total prevalence of 7.50%.ConclusionWe herein validated an algorithm for the diagnosis of diabetes using administrative claims against the clinical diagnosis. Together with rHIE laboratory data, this allowed to identify possibly undiagnosed diabetes and estimate the true prevalence of diabetes in Veneto.     

24-h urinary sodium excretion and the risk of adverse outcomes

Abstract

Aims

The objective was to evaluate whether sodium intake, assessed with the gold standard 24-h urinary collections, was related to long-term incidence of death, cardiovascular disease (CVD) and diabetes mellitus (DM).     

“血尿”“三问十二字”临床教学思路探讨

血尿是肾病科常见的临床表现,对于血尿的病因诊断分析在临床中不容易掌握,有漏诊的风险,因此需要系统而全面的诊断思路。我科在临床教学中总结了"三问十二字"的教学思路,收到较好的效果。三问包括第一问尿液呈现红色是否为血尿?第二问为符合血尿是否为病理状态?第三问为血尿一定是否只有肾脏疾病?通过三问来明确血尿的定义,并逐渐剖析临床非血尿、真性血尿、假性血尿、内科性血尿以及外科性血尿的意义。再通过内科性血尿的特点高度概括出"十二个字",以帮助学生区分内科性血尿及外科性血尿。通过"三问十二字"的深入浅出学习,可以将血尿复杂的诊断思路由繁入简掌握,并实践于临床。

Preservation of Renal Function after Major Bleeding Events due to Ultrasound-Guided Parenchymal Renal Biopsy

The clinical outcomes of major bleeding events following ultrasound-guided native and allograft parenchymal renal biopsy were evaluated. Forty-eight bleeding complications after biopsy (Society of Interventional Radiology adverse event grade ≥ 2) from 2002 to 2018 were identified. The primary outcome assessed was renal function. The clinical outcomes and interventions performed, including blood transfusion, angiography with or without embolization, nephrostomy tube placement, surgery, nephrectomy, hospitalization, intensive care unit admission, dialysis, and survival, were noted. Renal function may be moderately diminished in the short-term periprocedural setting. None of the patients studied died or required nephrectomy or the initiation of dialysis as a result of a major bleeding complication after the renal biopsy.
