Diabetic Care in Nursing Homes

Diabetes is one of the most common chronic conditions in U.S. nursing homes, and the medication regimens used to manage it are also among the most error-prone. Insulin is classified as a high-alert medication by the Agency for Healthcare Research and Quality (AHRQ), meaning small mistakes can cause serious harm. When a facility fails to monitor blood glucose, misses insulin doses, or lets foot wounds go unchecked, the consequences can include hypoglycemic falls, diabetic ketoacidosis, amputation, and sepsis. Diabetic care failures are a recognized form of nursing home neglect under federal long-term care regulations.

This article draws on the American Diabetes Association (ADA) Standards of Care in Diabetes, the ADA position statement on diabetes management in long-term care, peer-reviewed geriatrics literature, federal regulations at 42 CFR Part 483, and findings from the HHS Office of Inspector General (OIG). It explains how diabetes should be managed in a nursing home setting, the most common ways that care falls short, and what families can do when they suspect a problem.

How Common Diabetes Is Among Nursing Home Residents

Diabetes is disproportionately common in long-term care populations. According to the CDC/NCHS Data Brief No. 454 (December 2022), 17% of U.S. residential care community residents had diagnosed diabetes in 2020, based on the 2020 National Post-acute and Long-term Care Study.

Peer-reviewed estimates for skilled nursing facilities run higher. A 2022 review by Munshi and colleagues published in the Journal of the American Geriatrics Society (PMC9305812) places diabetes prevalence in U.S. nursing homes at 20% to 34%, roughly double the adult population rate. The CDC National Diabetes Statistics Report notes that 28.8% of U.S. adults age 65 and older have diabetes (diagnosed or undiagnosed), and another 52.1% have prediabetes. Long-term care residents skew older and sicker, which helps explain the elevated prevalence.

The NIDDK volume Diabetes in America (Chapter 16: Diabetes in Older Adults) documents that diabetes in this setting is associated with longer nursing home stays, higher comorbidity burden, and a greater incidence of geriatric syndromes including falls, cognitive impairment, and functional decline.

What Good Diabetic Care Looks Like in Long-Term Care

Federal law requires nursing homes to help each resident attain or maintain the "highest practicable physical, mental, and psychosocial well-being." The Nursing Home Reform Act codifies this standard at 42 CFR § 483.25 (Quality of care), which states that "the facility must ensure that residents receive treatment and care in accordance with professional standards of practice, the comprehensive person-centered care plan, and the resident's choices." CMS surveyors cite diabetes-care deficiencies under this regulation at F-tag F684 (Quality of Care) when no more specific tag applies.

Person-centered care planning under 42 CFR § 483.21

Under 42 CFR § 483.21, each resident must have a comprehensive, person-centered care plan developed by an interdisciplinary team within seven days of the required Minimum Data Set assessment. For a resident with diabetes, the plan must address glycemic goals, medication regimen, diet, blood glucose monitoring schedule, foot care, and the response protocol for hypoglycemia. A care plan that omits any of these elements for a resident on insulin is a care-planning deficiency in its own right.

Glycemic targets appropriate for older adults

Chapter 13 of the ADA Standards of Care in Diabetes — 2026 (Older Adults) recommends individualized glycemic targets based on a three-tier health-status framework, and it emphasizes that avoiding hypoglycemia is the primary priority for older adults with advanced comorbidity. Target ranges according to the ADA:

• Healthy older adults: A1c below 7.0%-7.5%
• Residents with complex or intermediate health: A1c below 8.0%
• Residents with very complex or poor health (including many long-stay nursing home residents): the ADA advises against relying on an A1c number and instead focusing on avoiding hypoglycemia and symptomatic hyperglycemia

The 2016 ADA position statement on Management of Diabetes in Long-term Care and Skilled Nursing Facilities (published in Diabetes Care, Munshi et al.) recommends basal insulin regimens and, where clinically appropriate, newer agents such as DPP-4 inhibitors, GLP-1 receptor agonists, and SGLT-2 inhibitors over regimens that frequently cause hypoglycemia.

High-Risk Medications and the Risk of Hypoglycemia

Insulin and sulfonylureas are the two drug classes most commonly implicated in severe hypoglycemia in older adults, according to the 2016 ADA position statement and the 2022 Munshi review. In one long-term care cohort summarized by Munshi and colleagues, insulin accounted for roughly 64% of hypoglycemic events and sulfonylureas for about 19%. Up to 42% of long-term care residents with diabetes in that review had a blood glucose reading below 70 mg/dL, and 7% had episodes below 54 mg/dL. For more on broader drug-administration failures, see our guide to nursing home medication errors.

A clinical surveillance study by Pandya and colleagues (PMC4778416) measured drug-associated hypoglycemia at 9.5 events per 1,000 resident-days in nursing home residents, with insulin orders linked to 98.7% of surveillance alerts. AHRQ's PSNet primer on medication errors and adverse drug events identifies insulin as one of a small group of high-alert medications responsible for a disproportionate share of serious adverse drug events across care settings.

The problem with sliding-scale insulin

Sliding-scale insulin (SSI) is a regimen in which short-acting insulin is administered in reaction to elevated glucose readings, without a scheduled basal insulin component. The 2016 ADA position statement on long-term care diabetes management concluded that the sole use of sliding-scale insulin should be avoided in this setting. The American Geriatrics Society's Choosing Wisely list includes a similar recommendation: do not use sliding-scale insulin for long-term diabetes management in nursing home residents.

A 21-day randomized controlled trial by Dharmarajan and colleagues, published in JAMDA in 2016 and conducted across 14 U.S. long-term care facilities, found that basal-bolus insulin produced better glycemic control than sliding-scale insulin in older nursing home residents.

Consultant pharmacist review under 42 CFR § 483.45

Under 42 CFR § 483.45 (Pharmacy services), each resident's drug regimen must be free from unnecessary drugs and must be reviewed at least once a month by a licensed pharmacist. Diabetes medications flagged by the consultant pharmacist must be communicated to the attending physician. CMS enforces this requirement at F-tag F757 (Drug Regimen Free from Unnecessary Drugs).

Common Forms of Diabetic Neglect

The HHS Office of Inspector General's 2014 report Adverse Events in Skilled Nursing Facilities (OEI-06-11-00370) found that 22% of Medicare SNF beneficiaries experienced an adverse event during a covered stay, with another 11% experiencing temporary-harm events. Physicians reviewing the files judged 59% of those events to be clearly or likely preventable. Medication-related events, including insulin-related hypoglycemia, were among the most common categories. The following are recurring patterns in diabetic-care failures.

Missed or incorrect insulin doses

Missed fingersticks, delayed insulin administration relative to meals, and dosing errors are documented drivers of hypoglycemic and hyperglycemic crises in long-term care. AHRQ's PSNet case study "Challenges of Diabetes Management and Medication Reconciliation" documents how reconciliation errors at care transitions in older adults with diabetes commonly lead to hypoglycemic readmissions.

Inadequate blood glucose monitoring

The ADA Standards of Care 2026 recommend capillary point-of-care glucose testing before meals and at bedtime for residents on insulin, with continuous glucose monitoring (CGM) as an emerging option for residents at elevated hypoglycemia risk. A blood glucose flow sheet with missing entries, or values outside ordered parameters without a documented nursing response, is a red flag for inadequate monitoring.

Failure to recognize hypo- or hyperglycemia

Older adults often present atypically. The NIH National Institute on Aging notes that low blood sugar in older adults can manifest as new confusion, falls, slurred speech, or behavior change rather than classic sweating and tremor. Cognitive impairment can mask a resident's ability to report symptoms at all, which places the burden of recognition on direct-care staff.

Poor diet and inconsistent meal timing

Federal rules at 42 CFR § 483.60 require that each resident receive a nourishing, palatable, well-balanced diet that meets daily nutritional and special dietary needs. Mismatched meal timing relative to insulin administration, inadequate snacks between meals, or unaddressed food refusal are recognized drivers of hypoglycemia according to the 2016 ADA position statement.

Consequences of Untreated Diabetic Neglect

Diabetic care failures do not stay on the medication administration record. They show up as acute events and long-term complications that drive hospitalizations, functional decline, and death.

Hypoglycemic events and falls

Severe hypoglycemia in older adults is associated with falls, fractures, cardiovascular events, accelerated cognitive decline, and increased mortality, according to the ADA Standards of Care 2026 and NIDDK guidance on managing older adults with diabetes.

Diabetic ketoacidosis and hyperosmolar hyperglycemic syndrome

Both conditions are medical emergencies. NIH/NCBI StatPearls reports DKA mortality rising from roughly 8% at ages 60-69 to about 27% at ages 70-79 and around 33% at age 80 and older. Hyperosmolar Hyperglycemic Syndrome (HHS) carries a mortality rate as high as 20%, roughly ten times that of DKA, and is classically described in institutionalized elderly patients with diminished thirst perception or limited ability to access fluids.

Foot ulcers, infection, and amputation

A 2023 Diabetes Care review by Armstrong and colleagues reports that approximately 1.6 million Americans develop a diabetic foot ulcer each year; lifetime foot-ulcer risk among people with diabetes is 19% to 34%. Roughly 50% to 60% of diabetic foot ulcers become infected, and about 20% of moderate-to-severe diabetic foot infections progress to lower-extremity amputation. Preventable amputation is a well-documented endpoint of foot-care neglect in long-term care.

Infections and sepsis

Hyperglycemia impairs neutrophil function and wound healing. The 2022 Munshi review notes that diabetes is a documented risk factor for urinary tract infection, pneumonia, skin and soft tissue infection, and sepsis in long-term care populations.

Foot Care and Preventing Amputation

Foot care in long-term care is a nursing responsibility, not just a podiatrist's job. The ADA Standards of Care 2026 recommend an annual comprehensive foot examination for all adults with diabetes and a visual foot inspection at every routine visit for residents at elevated risk (those with neuropathy, prior ulceration, foot deformity, or peripheral arterial disease). The 2016 ADA position statement and the Armstrong 2023 review describe daily foot inspection by trained staff as a standard expectation for residents with known neuropathy or prior ulceration.

Other core elements include:

• Protective footwear and therapeutic shoe programs (covered under Medicare Part B for qualifying beneficiaries with diabetes, per NIDDK Diabetes in America, Chapter 16)
• Podiatry consultation for residents with high-risk feet; delays in podiatry or wound-care referral are a recognized driver of preventable amputation (Armstrong et al., 2023)
• Documentation of skin checks on the care plan and in the medical record, so that changes can be tracked over time

Warning Signs Families Can Recognize

Families are often the first to notice a change. Signs that may point to diabetic care problems, drawn from NIA, NIDDK, and StatPearls clinical references, include:

• Sudden confusion, sweating, tremor, slurred speech, or new weakness (classic and atypical signs of hypoglycemia in older adults, per NIA Diabetes in Older People)
• New or non-healing wounds on the feet, redness, drainage, or foul odor (Armstrong et al., 2023)
• Unexplained hospitalizations, especially for hypoglycemia, DKA, HHS, or infection
• Excessive thirst, frequent urination, altered mental status, or rapid weight loss (NIDDK overview of diabetes complications in older adults)
• Documentation gaps on the medication administration record (MAR) or blood glucose flow sheet: missed fingersticks, missing insulin doses, or glucose values outside ordered parameters without a nursing response

Federal Care Standards That Apply

Four provisions of 42 CFR Part 483 apply most directly to diabetic care in a nursing home:

• 42 CFR § 483.25 (Quality of care). The general quality-of-care requirement, cited at F-tag F684 when diabetes care falls below professional standards.
• 42 CFR § 483.21 (Comprehensive person-centered care planning). Governs the diabetes care plan itself, including glycemic goals, medication regimen, monitoring, diet, and hypoglycemia response.
• 42 CFR § 483.45 (Pharmacy services). Requires that each resident's drug regimen be free from unnecessary drugs and reviewed at least monthly by a licensed pharmacist. Diabetes-related pharmacy deficiencies are cited at F-tags F755, F756, F757, F758, F759, and F760.
• 42 CFR § 483.60 (Food and nutrition services). Requires nourishing, palatable, well-balanced meals that meet each resident's daily nutritional and special dietary needs — the federal basis for diabetic-diet coordination.

What Families Should Do If They Suspect Diabetic Neglect

Residents and their legal representatives have broad rights of access to records and grievance processes under 42 CFR § 483.10 (Resident rights). If you suspect diabetic care failures, the following steps are supported by the federal framework and by AHRQ PSNet guidance on adverse drug events:

• Request the medication administration record (MAR), blood glucose flow sheet, care plan, and any incident reports in writing.
• Escalate concerns in writing to the director of nursing and medical director, documenting dates, values, and witnessed events.
• File a complaint with the state survey agency (CMS-certified nursing homes are surveyed by state health departments under contract with CMS) and with the state Long-Term Care Ombudsman program.
• Call 911 for acute hypoglycemia unresponsive to food, altered mental status, suspected DKA, or suspected HHS. NIH/NCBI StatPearls documents the high mortality of these conditions in older adults.

State survey agency and ombudsman contact information varies by state. See our guides for Texas, Florida, and Georgia. If a resident has been seriously harmed, you can also speak to a lawyer about your options. Diabetic care failures can overlap with patterns covered in our broader guides to nursing home abuse and nursing home injuries.
