Reports Outline Acute Coronary Syndrome Study Findings from Nara Medical University (Validity of Diagnostic Algorithms for Cardiovascular Diseases In Japanese Health Insurance Claims): Heart Disorders and Diseases – Acute Coronary Syndrome

2023 MAY 10 (NewsRx) -- By a News Reporter-Staff News Editor at Insurance Daily News -- Researchers detail new data in Heart Disorders and Diseases - Acute Coronary Syndrome. According to news reporting out of Kashihara, Japan, by NewsRx editors, research stated, “We aimed to validate a claims-based diagnostic algorithm to identify hospitalized patients with acute major cardio-vascular diseases (CVDs) from health insurance claims in Japan. This retrospective multicenter validation study was conducted at 4 institutes, including Japanese Circulation Society-certified and uncertified hospitals in Japan.”

Funders for this research include Ministry of Health, Labour and Welfare, Japan, Cardiovascular diseases of National Cerebral and Cardiovascular Center.

Our news journalists obtained a quote from the research from Nara Medical University, “Data on patients with CVDs in departmental lists or with International Classification of Diseases, 10th Revision (ICD-10) codes for CVDs hospitalized between April 2018 and March 2019 were extracted. We examined the sensitivity and positive predictive value of a diagnostic algorithm using ICD-10 codes, medical examinations, and treatments for acute coronary syndrome (ACS), acute heart failure (HF), and acute aortic disease (AAD). We identified 409 patients with ACS (mean age 70.6 years; 24.7% female), 615 patients with acute HF (mean age 77.3 years; 46.2% female), and 122 patients with AAD (mean age 73.4 years; 36.1% female). The respective sensitivity and positive predictive value for the algorithm were 0.86 (95% confidence interval [CI] 0.82-0.89) and 0.95 (95% CI 0.92-0.97) for ACS; 0.74 (95% CI 0.70-0.77) and 0.79 (95% CI 0.76-0.83) for acute HF; and 0.86 (95% CI 0.79-0.92) and 0.83 (95% CI 0.76-0.89) for AAD. The validity of the diagnostic algorithm for Japanese claims data was acceptable.”

According to the news editors, the research concluded: “Our results serve as a foundation for future studies on CVDs using nationwide administrative data.”

This research has been peer-reviewed.
