Antibiotics prescriptions for pneumonia analyzed by claim information in Japan.

Objective: Japan is an aging society, and pneumonia is the leading cause of death, but the suitability of antibiotics for treating community-acquired pneumonia (CAP) in Japan is not clear. The purpose of this study was to investigate antibacterial drugs for treating CAP according to age.

Materials And Methods: Using the Japanese national database from 2011 to 2014, we analyzed the usage of antibiotics for CAP according to age.

Antibiotics for hospitalized children with community-acquired pneumonia in Japan: Analysis based on Japanese national database.

Introduction: Community-acquired pneumonia (CAP) is one of the most common causes of pediatric infection requiring hospitalization. Antimicrobial resistance due to the inappropriate use poses a threat worldwide. Our objective is to analyze and optimize the trends of antibiotics used for pediatric inpatients with CAP in a claims database provided by the Ministry of Health, Labour and Welfare.

A retrospective observational study of antibiotics treatment for sepsis using a nationwide claim database in Japan.

Survival Sepsis Campaign (SSC) guidelines have recommended broad-spectrum antibiotics prescriptions to cover the possible pathogenic microorganisms. However, mortality from sepsis is still high, as about one quarter of cases are thought to result in death. We analyzed nationwide health claims data of universal health insurance systems in Japan.

A retrospective observational study of antimicrobial treatment for non-tuberculous mycobacteria disease using a nationwide claims database in Japan.

The Macrolides (MLs), clarithromycin and azithromycin, are key drugs for non-tuberculous mycobacteria (NTM) diseases treatment. A three antibiotics regimen including MLs, rifampicin (RFP) and ethambutol (EB) has been recommended for the treatment of NTM diseases in ATS/IDSA guideline. However, anti-biotics are not necessarily prescribed in compliance with the guideline.

Epidemiology and treatment outcome of pneumonia: Analysis based on Japan national database.

Pneumonia is the third leading cause of death in Japan. Mortality increases at an accelerating rate in elderly patients aged ≥65 years. Elderly patients tend to have underlying conditions affecting pneumonia treatment.

Microorganisms isolated at admission and treatment outcome in sputum smear-positive pulmonary tuberculosis.

Cured or completed cases in newly diagnosed sputum smear-positive pulmonary tuberculosis (TB) is 47.7% in Japan in 2016. Aging of TB patients and their underlying conditions could affect treatment outcome.

The effects of pirfenidone in patients with an acute exacerbation of interstitial pneumonia.

Introduction: The prognosis of patients with an acute exacerbation of interstitial pneumonia (AE-IP) is poor. Pirfenidone (PFD) reduces the disease progression in idiopathic pulmonary fibrosis.

Objectives: The purpose of this study was evaluating whether the administration of PFD improved the outcomes of AE-IP.

Predictive factors for the effect of pirfenidone in idiopathic pulmonary fibrosis.

Pirfenidone is one of the anti-fibrotic drugs used for patients with idiopathic pulmonary fibrosis. Pirfenidone exerts anti-inflammatory effects by inhibiting the influx of inflammatory cells. The purpose of this study was to clarify the differences in the baseline parameters in responsive and unresponsive patients, and to assess the clinical and radiological changes after pirfenidone therapy.
