Identification of Patient Profiles with High Risk of Hospital Re-Admissions for Acute COPD Exacerbations (AECOPD) in France Using a Machine Learning Model.

Purpose: To characterise patients with chronic obstructive pulmonary disease (COPD) who are rehospitalised for an acute exacerbation, to estimate the cost of these hospitalisations, to characterise high risk patient sub groups and to identify factors potentially associated with the risk of rehospitalisation.

Patients And Methods: This was a retrospective study using the French National Hospital Discharge Database. All patients aged ≥40 years hospitalised for an acute exacerbation of COPD between 2015 and 2016 were identified and followed for six months.

Prospective randomized study comparing the medicoeconomic benefits of Hylan GF-20 vs. conventional treatment in knee osteoarthritis.

Objectives: In a previous study, we determined the costs over 6 months to the French public health insurance system of Hylan GF-20 (Synvisc) in 66 patients with knee osteoarthritis. Here, we compared the medicoeconomic benefits over 9 months in 506 patients given Hylan GF-20 or conventional treatment for knee osteoarthritis.

Patients And Methods: This prospective randomized study was conducted from October 1998 to February 2000.
