Aims:
To identify incidental previously unrecognized diabetes (IPUD) among hospitalized patients and corresponding mortality risk in comparison with individuals with known diabetes (KDM).
Methods:
Out of 214,991 individuals discharged in year 2011 from all hospitals of Tuscany, Italy we retrospectively identified IPUD as individuals with no known diabetes and/or previous antidiabetic medication, receiving at least two prescriptions of glucose-lowering-drugs over the next 6months after discharge. Two-year (2012-2013) adjusted mortality risk was tested by a Cox-regression-analysis, comparing IPUD and KDM patients with at least one hospital admission in 2011.
Results:
974 patients with IPUD (375.6×100,000 hospitalized people) have been identified. IPUD risk was associated with aging, male gender and greater burden of co-morbidities, was higher in migrants of non-Italian ancestry and was reduced among patients of family physicians adhering to guidelines resulting in a proactive model of care delivery. In IPUD patients alive at 1st January 2012, (n=865) the adjusted risk of two-year mortality was similar to that of KDM subjects (HR=1.08; 95% CI: 0.92-1.26; p=NS).
Conclusions:
IPUD occurs more commonly in older male subjects, migrants of non-Italian ancestry, and among patients of physicians non-adhering to a shared diabetes care model. People with IPUD have similar two-year-mortality risk compared with KDM individuals.
