While T2DM is recognised to be associated with multimorbidity and early mortality, people with NDH are frequently thought to be devoid of such complications, potentially exposing individuals with NDH to suboptimal care. We therefore used the Discover London Secure Data Environment (SDE) dataset to appreciate the relationship of NDH/T2DM with multimorbidity, healthcare usage, and clinical outcomes.<h4>Research design and methods</h4>The dataset was retrospectively analysed between January 1, 2015 and December 31, 2020 to understand the relationship between NDH/T2DM and multimorbidity primary/secondary healthcare usage and clinical outcomes. This was compared with a cohoBMJ open diabetes research & careReal-world study of the multimorbidity and health service utilisation among individuals with non-diabetic hyperglycemia and type 2 diabetes mellitus in North West London.PMC11409243N/AShah MFrankel AHLucas AUl-Haq ZKamalati TGriffiths TPierce BWillis TBaruwa ABickford-Smith LChilcott JTam FWKDattani RfalseReal-world study of the multimorbidity and health service utilisation among individuals with non-diabetic hyperglycemia and type 2 diabetes mellitus in North West London.<h4>Introduction</h4>The prevalence of non-diabetic hyperglycemia (NDH) and type 2 diabetes mellitus (T2DM) is increasing.
