Deintensification of Diabetes Medications among Veterans at the End of Life in VA Nursing Homes

OBJECTIVES Many older adults with limited life expectancy and/or advanced dementia (LLE/AD) are potentially overtreated for diabetes and may benefit from deintensification. Our aim was to examine the incidence and predictors of diabetes medication deintensification in older Veterans with LLE/AD who were potentially overtreated at admission to Veterans Affairs (VA) nursing homes (community living centers [CLCs]). DESIGN Retrospective cohort study using linked VA and Medicare clinical/administrative data and Minimum Data Set assessments. SETTING VA CLCs. PARTICIPANTS A total of 6960 Veterans with diabetes and LLE/AD admitted to VA CLCs in fiscal years 2009 to 2015 with hemoglobin (Hb)A1c measured within 90 days of admission. MEASUREMENTS We evaluated treatment deintensification (discontinuation or dose reduction for a consecutive 7‐day period) among residents who were potentially overtreated (HbA1c ≤7.5% and receiving hypoglycemic medications). Competing risk models assessed 90‐day cumulative incidence of deintensification. RESULTS More than 40% (n = 3056) of Veteran CLC residents with diabetes were potentially overtreated. The cumulative incidence of deintensification at 90 days was 45.5%. Higher baseline HbA1c values were associated with a lower likelihood of deintensification (e.g., HbA1c 7.0‐7.5% vs
