Background/Objectives: An increasing proportion of patients with Type 2 diabetes mellitus (T2DM) are classified as high risk, often presenting with multimorbidity, functional vulnerability, and complex treatments. This study compared the sociodemographic, functional, clinical, therapeutic, and healthcare utilization profiles of high-risk chronic patients with and without T2DM in primary health care. Methods: A cross-sectional study included adults classified as high-risk chronic patients in primary health care electronic health records in the Madrid Region (30 April 2021). Sociodemographic, functional, clinical, lifestyle, pharmacological variables, and primary health care services utilization were analyzed. Multivariate logistic regression identified factors independently associated with T2DM. Results: Among 163,188 high-risk chronic patients, 41.5% had T2DM. Patients with T2DM were older, more often male, and had a comparable deprivation index values to non-diabetic patients. They showed higher functional dependency and greater need for informal caregiving. Clinically, patients with T2DM had a higher burden of chronic conditions and a predominance of cardiometabolic, hematological and renal comorbidities, whereas non-diabetic patients exhibited more neuropsychiatric, chronic infectious, oncological and respiratory profiles. Polypharmacy was more frequent in T2DM patients, who also showed lower medication adherence. In the explanatory model, older age (OR 1.02/year), cardiometabolic comorbidities (ORs ~1.2–1.6), highest quartile of morbidity complexity (OR 1.27), polypharmacy (OR 1.34), and concern about medications (OR 1.08) were associated with T2DM, while female sex (OR 0.660), depression (OR 0.888), COPD (0.704), neoplasms (0.688), and higher medication adherence (OR 0.53) were associated with not having T2DM. Conclusions: High-risk chronic patients with T2DM exhibit distinct sociodemographic, functional, and clinical profiles compared with those without T2DM, characterized by greater complexity, cardiometabolic burden, therapeutic intensity and use of healthcare services, supporting the need for tailored, integrated primary health care strategies.
