#1346 Inpatient and outpatient service review of a Greek reference centre for glomerular diseases

Abstract

Abstract Background and Aims The glomerulonephritis (GN) is a rare and complicated disease with high demand of hospital resources while the chronic kidney disease and end-stage renal disease present increased prevalence in these patients. Method We retrospectively assessed the inpatient and outpatient service of a Greek reference centre for glomerular diseases during the pre-Covid-19 period 2018-2020. Results 267 patients (38% female, median age 65 ± 23 years) included. All patients underwent a kidney biopsy by the nephrologist without complications. ANCA associated GN (18%), Focal Segmental Glomerulosclerosis/Minimal Change Disease (17.5%), IgA nephropathy (17%), Membranous Nephropathy (12.6%), Lupus Nephritis (5%), Membranoproliferative GN (3%), Fibrillary GN (3%), Monoclonal Gammopathy of Renal Significance (3.3%) and IgG4-related disease (2%.) are encompassed. We reported median 75 new patients per year. Regarding the inpatient service, we observed an increasing trend to the hospitalizations during this period (274, 452, 461 hospitalizations in 2018, 2019, 2020 respectively). The AAGN was the most common disease of hospitalizations through this period (53% in 2018, 33% in 2019, 39% in 2020), whereas the second most common was the FSGS/MCD (28% in 2018, 13% in 2019, 23.8% in 2020). The outpatient's service review also revealed an increasing number of visits per person per year (279, 456 and 464 total visits in 2018, 2019 and 2020 respectively). The disease with the highest number of visits per person was reported the AAV (median 3.25 visits per patient per year). All the patients were managed in adherence to the latest guidelines for GN in collaboration with a multidisciplinary team, consisting of nephrologist, rheumatologist, cardiologist, and pathologist. Finally, we reported complete response at 76% of the patients and in terms of renal improvement, 46% presented eGFR≥60 ml/min/1.73 m2, 45% eGFR<60 ml/min/1.73 m2 and only 9% progressed to ESRD after the first year of treatment. Conclusion Patients with GN present an increased need for hospitalization and regular outpatient visits. Addressing these diseases necessitates the expertise of a multidisciplinary team to provide comprehensive care that maximizes the potential for sustained positive long-term outcomes.
