Descriptions des hospitalisations au cours de l’année 2019 des patients dialysés en France

Abstract

IntroductionThe possibility of indirect linkage between data from the French REIN registry and data from the National Health Data System makes it possible to enhance knowledge of the care pathway of patients with severe kidney disease. Taking an interest in hospitalizations makes it possible to understand the burden of this disease, both for patients, in terms of comorbidities, complications and quality of life but also for society in terms of care load, need for organization of the care offer and costs. MethodsPatients on dialysis in 2019 were identified from REIN. The information on hospital stays comes from an extraction of the National Health Data System linked with REIN. The hospitalization rate corresponds to the number of hospital stays over the period, relative to the number of people at risk on dialysis over the period. ResultsAfter excluding dialysis sessions, 36,962 patients had a hospital stay in 2019: 36,738 in medicine, surgery, obstetrics, 2863 in rehabilitation, 531 in home hospitalizations and 201 in psychiatry facilities. This represents a total of 146,743 stays, including 140,372 in medicine, surgery, obstetrics. The hospitalization rate in medicine, surgery, obstetrics is 259 stays for 100 person-years. The reasons vary according to age, type of hospitalization (with or without overnight stays) and mode of discharge (home, death or transfer). The median amounts for a stay vary from €7920 in rehabilitation to €719 in medicine, surgery, obstetrics without overnight stay. Due to the volumes, stays for cardiovascular pathology represent a high total amount over the year. Hospitalizations for infection have significant median costs. Discussion and conclusionThe results presented in this article confirm the important place of hospitalization in the trajectory of dialysis patients. Hospitalizations in medicine, surgery, obstetrics represent 96% of hospitalizations. For the first time, this study shows the very low place of hospitalizations in psychiatry and rehabilitation facilities.
