This study aimed to validate a claims-based diagnostic algorithm for identifying hospitalized patients with acute major cardiovascular diseases in Japan. The algorithm showed acceptable validity in Japanese claims data, providing a foundation for future studies on cardiovascular diseases using nationwide administrative data.
Background: 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.Methods and Results: This retrospective multicenter validation study was conducted at 4 institutes, including Japanese Circulation Society-certified and uncertified hospitals in Japan. 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.Conclusions: The validity of the diagnostic algorithm for Japanese claims data was acceptable. Our results serve as a foundation for future studies on CVDs using nationwide administrative data.

Summary: This study aimed to investigate the variations in care quality for patients with acute coronary syndrome (ACS) and its association with mortality at both hospital and patient levels. The analysis of a nationwide database revealed substantial variations in ACS care. High adherence to quality indicators was associated with significant survival gains at both levels, indicating the effectiveness of a multi-level approach in improving survival for this population.

Summary: This study investigated the effects of outpatient cardiac rehabilitation in patients with heart failure using a nationwide database. The results showed that outpatient cardiac rehabilitation was associated with a reduction in mortality and rehospitalization for heart failure without increasing medical costs.

Summary: This retrospective cohort study examined the association of early use of SGLT2 inhibitors with outcomes in hospitalized patients with acute coronary syndrome. The results showed that SGLT2 inhibitors were associated with a lower risk of the primary outcome in patients with severe heart failure, but not in patients without severe heart failure.

Summary: This study used data from the National Database of Health Insurance Claims and Specific Health Check-ups to examine the change in outpatient visits in Japan during the COVID-19 pandemic. The results showed a 9.98% decrease in the number of outpatient visits per million people in 2020 compared to 2019. The decrease was observed in visits for infectious and chronic diseases. The analysis method using actual health insurance claim data can be applied globally.

Summary: The participation of Japanese patients in outpatient cardiac rehabilitation (CR) is still low. Age, multiple comorbidities, and low institutional capacity were identified as significant factors contributing to this lower participation rate. Understanding these associated factors can help cardiologists increase CR participation among patients.

Summary: This study modifies the data structure of the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) using the ID0 key, allowing for long-term cohorts without increasing data volume or runtime. The modified structure improves patient-matching efficiency and long-term tracing performance. The study showcases the application of this method in a six-year mortality cohort study of Japanese citizens, demonstrating its ability to accurately trace patient data in large-scale medical claims databases.

Summary: During the COVID-19 pandemic, EMS played a crucial role in transporting emergency patients. This study aimed to assess the diagnostic accuracy of a prehospital COVID-19 screening protocol for EMS. The findings showed that the current screening protocol had low sensitivity and positive predictive value for diagnosing COVID-19, but adding vital signs improved its diagnostic value.
