Abstract

OBJECTIVE: Older adults with diabetes and dementia are at increased risk for hypoglycemia and other adverse events associated with tight glycemic control and are unlikely to experience long-term benefits. We examined risk factors for tight glycemic control in this population and use of medications associated with a high risk of hypoglycemia in the subset with tight control. RESEARCH DESIGN AND METHODS: This retrospective cohort study of national Veterans Affairs (VA) administrative/clinical data and Medicare claims for fiscal years (FYs) 2008–2009 included 15,880 veterans aged ≥65 years with type 2 diabetes and dementia and prescribed antidiabetic medication. Multivariable regression analyses were used to identify sociodemographic and clinical predictors of hemoglobin A1c (HbA1c) control (tight, moderate, poor, or not monitored) and, in patients with tight control, subsequent use of medication associated with a high risk of hypoglycemia (sulfonylureas, insulin). RESULTS: Fifty-two percent of patients had tight glycemic control (HbA1c <7% [53 mmol/mol]). Specific comorbidities, older age, and recent weight loss were associated with greater odds of tight versus moderate control, whereas Hispanic ethnicity and obesity were associated with lower odds of tight control. Among tightly controlled patients, 75% used sulfonylureas and/or insulin, with higher odds in patients who were male, black, or aged ≥75 years; had a hospital or nursing home stay in FY2008; or had congestive heart failure, renal failure, or peripheral vascular disease. CONCLUSIONS: Many older veterans with diabetes and dementia are at high risk for hypoglycemia associated with intense diabetes treatment and may be candidates for deintensification or alteration of diabetes medications.

  • Intensive glycemic management with medication plans including insulin and sulfonylureas in older adults with complex medical conditions has been identified as overtreatment.

    “Intensive glycemic management with medication plans including insulin and sulfonylureas in older adults with complex medical conditions has been identified as overtreatment and found to be very common in clinical practice (100-104)”

    From 13. Older Adults: Standards of Care in Diabetes—2025 (2025) · cites this paper as [103]

    The Introduction says older adults with dementia should generally avoid tight glycemic control, and the Results report that 75% of tightly controlled patients used insulin and/or sulfonylureas. The Conclusions call for deintensification but also note that tighter targets or insulin may be appropriate for some patients. The study focuses on older veterans with dementia, so it does not establish that these regimens are invariably overtreatment across all older adults with complex medical conditions. Our copy provides no page numbers for these passages. (LLM, conf=0.84)

    The Results (Sample Characteristics; page not provided) report that 75% of tightly controlled patients used insulin and/or sulfonylureas, and the Conclusions describe a high rate of intense treatment in older patients with dementia. The evidence comes from a cohort of older veterans with diabetes and comorbid dementia, so it does not establish that this pattern is very common across all older adults with complex medical conditions. The paper also notes that tighter targets or insulin may be appropriate for some patients, rather than classifying every such regimen as overtreatment. (LLM, conf=0.86)

  • Intensive glycemic management in older adults with complex health status and medication plans that increase hypoglycemia risk through insulin and/or sulfonylureas has been identified as overtreatment and is common in clinical practice.

    “Intensive glycemic management in older adults, particularly those with complex health status, with medication plans that increase the risk of hypoglycemia through use of insulin and/or sulfonylureas has been identified as overtreatment, is common in clinical practice”

    From 13. Older Adults: Standards of Care in Diabetes—2026 (2026) · cites this paper as [112]

    The Results and Conclusions (page not available in our copy) show that tight glycemic control was common among older veterans with diabetes and dementia, and that 75% of tightly controlled patients used insulin and/or sulfonylureas. The paper describes this combination as a concern warranting possible deintensification, but its findings do not establish how common it is among older adults with complex health status generally. It also notes that tighter targets or insulin may be appropriate for some patients, so it does not classify every such regimen as overtreatment. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
