Objective

Although nursing home (NH) residents make up a large and growing proportion of Americans with diabetes mellitus, little is known about how glucose-lowering medications are used in this population. We sought to examine glucose-lowering medication use in Veterans Affairs (VA) NH residents with diabetes between 2005 and 2011.

Research design and methods

Retrospective cohort study, using linked laboratory, pharmacy, administrative, and NH Minimum Dataset (MDS) 2.0 databases in 123 VA NHs. A total of 9431 long-stay (>90 days) VA NH residents older than 65 followed for 52,313 person-quarters. We identified receipt of glucose-lowering medications, including insulin, metformin, sulfonylureas, thiazolidinediones, and others (alpha-glucosidase inhibitors, meglitinides, glucagonlike peptide-1 analogs, dipeptidyl peptidase-4 inhibitors and amylin analogs) per quarter.

Results

The rates of sulfonylurea use in long-stay NH residents dropped dramatically from 24% in 2005 to 12% in 2011 (P < .001), driven in large part by the dramatic decrease in glyburide use (10% to 2%, P < .001). There was sharp drop in thiazolidinedione use in 2007 (4% to <1%, P < .001). Metformin use was stable, ranging between 7% and 9% (P = .24). Insulin use increased slightly from 30% to 32% (P < .001). Use of other classes of glucose-lowering medications was stable (P = .22) and low, remaining below 1.3%.

Conclusions and relevance

Between 2005 and 2011, there were dramatic declines in use of sulfonylureas and thiazolidinediones in VA NH residents, suggesting that prescribing practices can be quickly changed in this setting.

Little is known about the quality of life (QoL) for informal caregivers of disabled older adults aged 65+ with diverse backgrounds. Forty-two caregivers were interviewed in English and Cantonese about their caregiving experiences, their recollections of QoL over time, and the factors influencing their appraisals. Overall, 52% of caregivers experienced a decline in QoL. Factors associated with decreased QoL were less time for self, competing financial demands, and the physical and emotional impact of the patient's illness. Factors associated with no change in QoL were minimal caregiving responsibilities, a sense of filial duty, and QoL being consistently poor over time. Factors associated with improved QoL were perceived rewards in caregiving, receiving institutional help, and increased experience. Chinese caregivers were more likely to cite filial duty as their motivator for continued caregiving than were Caucasian caregivers. In conclusion, informal caregivers take on a huge burden in enabling older adults to age in the community. These caregivers need more support in maintaining their QoL.
