Table 1. A Framework for Considering Treatment Goals for Glycemia, Blood Pressure, and Dyslipidemia in Older Adults with Diabetes.
Patient Characteristics/ Health Status |
Rationale | Reasonable A1C Goal (A lower goal may be set for an individual if achievable without recurrent or severe hypoglycemia or undue treatment burden) |
Fasting or Preprandial glucose (mg/dl) |
Bed- time glucose (mg/dl) |
Blood Pressure (mm Hg) |
Lipids |
---|---|---|---|---|---|---|
Healthy (Few co-existing chronic illnesses, intact cognitive and functional status) |
Longer remaining life expectancy | <7.5% | 90–130 | 90–150 | < 140/80 | Statin unless contraindicated or not tolerated |
Complex/Intermediate (Multiple co-existing chronic illnesses* or 2+ instrumental ADL impairments or mildmoderate cognitive impairment) |
Intermediate remaining life expectancy, high treatment burden, hypoglycemia vulnerability, fall risk | <8.0% | 90–150 | 100–180 | <140/80 | Statin unless contraindicated or not tolerated |
Very Complex/Poor Health (Long-term care or end-stage chronic illnesses** or moderate-severe cognitive impairment or 2+ ADL dependencies) |
Limited remaining life expectancy makes benefit uncertain. | <8.5%† | 100–180 | 110–200 | < 150/90 | Consider likelihood of benefit with statin (secondary prevention> primary) |
Co-existing chronic illnesses are conditions serious enough to require medications or lifestyle management and may include arthritis, cancer, congestive heart failure, depression, emphysema, falls, hypertension, incontinence, stage 3 or worse chronic kidney disease, myocardial infarction, and stroke. By multiple we mean at least 3, but many patients may have 5 or more (136).
The presence of a single end-stage chronic illness such as stage III–IV congestive heart failure or oxygen-dependent lung disease, chronic kidney disease requiring dialysis, or uncontrolled metastatic cancer may cause significant symptoms or impairment of functional status and significantly reduce life expectancy.
A1C of 8.5% equates to an estimated average glucose of ~200 mg/dl. Looser glycemic targets than this may expose patients to acute risks from glycosuria, dehydration, hyperglycemic hyperosmolar syndrome, and poor would healing.
