OBJECTIVES To examine the relationship between management of diabetes mellitus and hypoglycemia in older adults with and without dementia and cognitive impairment. DESIGN Cross-sectional database analysis of veterans aged 65 years and older stratified according to dementia, cognitive impairment, age, antiglycemic medications, and glycosylated hemoglobin(More)
IMPORTANCE Although serious hypoglycemia is a common adverse drug event in ambulatory care, current performance measures do not assess potential overtreatment. OBJECTIVE To identify high-risk patients who had evidence of intensive glycemic management and thus were at risk for serious hypoglycemia. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional study(More)
OBJECTIVE To evaluate patient-level glycemic control and facility variation of a proposed out-of-range (OOR) measure (overtreatment [OT] [HbA1c <7% (53 mmol/mol)] or undertreatment [UT] [>9% (75 mmol/mol)]) compared with the standard measure (SM) (HbA1c <8% [64 mmol/mol]) in high-risk older adults. RESEARCH DESIGN AND METHODS Veterans Health(More)
BACKGROUND It is unknown whether variability of estimated Glomerular Filtration Rate (eGFR) is a risk factor for dialysis or death in patients with chronic kidney disease (CKD). This study aimed to evaluate variability of estimated Glomerular Filtration Rate (eGFR) as a risk factor for dialysis or death to facilitate optimum care among high risk patients.(More)
OBJECTIVES To evaluate the effect of including of clinical actions within 6 months of a glycosylated hemoglobin (HbA1c) level greater than 8% upon measure adherence (pass rates) and to assess the association between patient factors and the likelihood of not passing. SETTING Veterans Health Administration. DESIGN Retrospective cohort study for FY2002 to(More)
Considering snow cover as a very important ecological factor, we performed this work to call attention of researchers to such a remarkable property of snow as a nonlinear correlation between snow cover depth and soil surface temperature under the cover. Indeed, as the snow cover reaches a certain depth, its further increase has a very little effect on soil(More)
