Original InvestigationPathogenesis and Treatment of Kidney DiseaseDetection and Awareness of Moderate to Advanced CKD by Primary Care Practitioners: A Cross-sectional Study From Italy
Section snippets
Data Source
Primary care–based data were obtained by the Health Search/Thales Database (HSD), set up by the Italian College of General Practitioners in 1998. It includes a large and representative sample of the Italian population and has the primary aim of carrying out observational studies of the incidence and prevalence of chronic diseases. GPs are recruited to include a number of patients proportional to the size of the population of their respective geographic locations. At the time of this study, the
Patient Characteristics
Practices of the 320 selected GPs covered a total of 541,351 Italian adults in 2003. We excluded 89,803 individuals with inadequate (<12 months) follow-up in primary care offices. Clinical characteristics of the 451,548 study participants of the entire practice population are listed in Table 1. The entire practice population was representative of the Italian population, exemplified by the age distribution of the HSD, which was similar to that of study participants included in the Italian Census
Discussion
This study evaluates the prevalence of decreased kidney function (CKD stages 3 to 5) in a large and representative sample of the Italian population followed up in primary care. We found that the age-standardized prevalence of eGFR less than 60 mL/min/1.73 m2 (<1.00 mL/s/1.73 m2) is 9.3% (11.9% in women, 6.5% in men), with the greatest rates detected in the elderly (27.8%). These data cannot be compared with prevalence estimates in the general population. Our aim is to explore the diagnostic

Kidney Function, Kidney Replacement Therapy, and Mortality in Men and Women
2022, Kidney International ReportsCitation Excerpt :Finally, because of the design of observational study, there is always a risk of unmeasured confounding. Nevertheless, in view of at least 3 previous sex-specific analyses of mortality and KRT initiation from CKD cohorts of the United States,16 Sweden,29 and Italy,35 it was an important opportunity to fill the knowledge gap on the general population. In summary, we found evidence that men were more likely to initiate KRT than women, which could not be explained by age, kidney function decline, and a wide range of comorbidities.
Mild to moderate chronic kidney disease and functional disability in community-dwelling older adults. The Cardiovascular risk profile in Renal patients of the Italian Health Examination Survey (CARHES) study
2019, Archives of Gerontology and GeriatricsCitation Excerpt :Overall CKD prevalence linearly increased with age, varying from 10.29% at age 65–69 to 21.44% at age ≥ 75 years. Of note, only 11.5% of individuals identified as having CKD were aware of the condition and/or had a documented diagnosis of CKD, strengthening the idea that CKD awareness remains disturbingly low in the general population and in the medical community as well (Jha et al., 2013; Minutolo et al., 2008). Maintaining functional independence is a fundamental aspect of healthy aging (Gopinath et al., 2013; Nordberg et al., 2007; Thai et al., 2013).
