Management of Diabetes During Acute Stroke and Inpatient Stroke Rehabilitation

Depression and Diabetes Mellitus Multimorbidity Is Associated With Loss of Independence and Dementia Poststroke

Background and Purpose:

Many patients with ischemic stroke present with multiple comorbidities that threaten survival and recovery. This study sought to determine the risks of adverse long-term stroke outcomes associated with multimorbid diabetes mellitus and depression.

Methods:

Retrospective analysis of prospectively collected data on consecutive patients without premorbid dementia admitted from the community for a first-ever acute ischemic stroke to comprehensive stroke centers across Ontario, Canada (2003–2013). Premorbid histories of diabetes mellitus and depression were ascertained within 5 years before stroke admission. Adjusted hazard ratios (aHR [95% CI]) of admission to long-term care, incident dementia, readmission for stroke or transient ischemic attack and all-cause mortality, over time among those discharged back into the community poststroke.

Results:

Among 23 579 stroke admissions, n=20 201 were discharged back into the community. Diabetes mellitus and depression were associated with synergistic hazards of admission to long-term care (X 2 =5.4; P =0.02) over a median follow-up of 5.6 years. This interaction was observed among women specifically; depression multimorbidity showed particularly high hazards of admission to long-term care (aHR Depression =1.57 [1.24–1.98]) and incident dementia (aHR Depression =1.85 [1.40–2.44]) among women with diabetes mellitus. In the whole cohort, diabetes mellitus and depression were associated individually with long-term care admission (aHR Diabetes =1.20 [1.12–1.29]; aHR Depression =1.19 [1.04–1.37]), incident dementia (aHR Diabetes =1.14 [1.06–1.23]; aHR Depression =1.27 [1.08–1.49]), stroke/transient ischemic attack readmission (aHR Diabetes =1.18 [1.10–1.26]; aHR Depression =1.24 [1.07–1.42]), and all-cause mortality (aHR Diabetes =1.29 [1.23–1.36]; aHR Depression =1.16 [1.05–1.29]).

Conclusions:

The risks of dementia and needing long-term care in the years after surviving a stroke were particularly elevated among women when premorbid diabetes mellitus and depression occurred together. Long-term stroke recovery strategies might target high-risk patients with mood and metabolic multimorbidity.

Implementation of a Multidisciplinary Diabetes Self-Management Training Class in Acute Rehabilitation

As a chronic medical condition, diabetes mellitus affects 29.1 million individuals in the United States. Since diabetes education reduces cost, there is a need for inpatient rehabilitation facilities to have education classes to address preexisting medical conditions, like diabetes. The purpose of this quality improvement project was to develop a class, determine feasibility, and explore the potential effectiveness. The intervention was Diabetes Self-Management Training Class with feasibility was quantified through (1) practicality (extent to which the intervention can be delivered), (2) acceptability (both of the participants and those participating in implementing the class), and (3) integration (how the class fit into the existing hospital infrastructure). With 42 participants, the class was practical, acceptable, as well as easily integrated into existing framework of the inpatient rehabilitation facility. While exploratory analysis using paired samples t-test revealed a significant average difference (p < .001) and a large effect size (d = 5.94), further research is required to determine effectiveness.

Inpatient Glycemic Management of Non-cardiac CVD: Focus on Stroke and PVD

PURPOSE OF REVIEW

Hyperglycemia occurs frequently in hospitalized patients with stroke and peripheral vascular disease (PVD). Guidelines for inpatient glycemic management are not well established for this patient population. We will review the clinical impact of hyperglycemia in this acute setting and review the evidence for glycemic control.

RECENT FINDINGS

Hyperglycemia in acute stroke is associated with poor short and long-term outcomes, and perioperative hyperglycemia in those undergoing revascularization for PVD is linked to increased post-surgical complications. Studies evaluating tight glucose control do not demonstrate improvement in clinical outcomes, although the risk for hypoglycemia increases substantially. Additional studies are needed to evaluate tight glucose goals relative to our current standard of care and the role of permissive hyperglycemia. Given the limited data to guide glycemic management in these patient populations, it is recommended that general guidelines for inpatient glycemic control be followed. Special considerations should be made to address factors that may impact glucose management, including neurological deficits and clinical changes that occur in the postoperative state.

Aging, the metabolic syndrome, and ischemic stroke: redefining the approach for studying the blood-brain barrier in a complex neurological disease

The blood-brain barrier (BBB) has many important functions in maintaining the brain's immune-privileged status. Endothelial cells, astrocytes, and pericytes have important roles in preserving vasculature integrity. As we age, cell senescence can contribute to BBB compromise. The compromised BBB allows an influx of inflammatory cytokines to enter the brain. These cytokines lead to neuronal and glial damage. Ultimately, the functional changes within the brain can cause age-related disease. One of the most prominent age-related diseases is ischemic stroke. Stroke is the largest cause of disability and is third largest cause of mortality in the United States. The biggest risk factors for stroke, besides age, are results of the metabolic syndrome. The metabolic syndrome, if unchecked, quickly advances to outcomes that include diabetes, hypertension, cardiovascular disease, and obesity. The contribution from these comorbidities to BBB compromise is great. Some of the common molecular pathways activated include: endoplasmic reticulum stress, reactive oxygen species formation, and glutamate excitotoxicity. In this chapter, we examine how age-related changes to cells within the central nervous system interact with comorbidities. We then look at how comorbidities lead to increased risk for stroke through BBB disruption. Finally, we discuss key molecular pathways of interest with a focus on therapeutic targets that warrant further investigation.

Diabetes prevalence and influence on resource use in Washington state inpatient rehabilitation facilities, 2001 to 2007

OBJECTIVE

To determine the prevalence of diabetes in inpatient rehabilitation facilities in Washington State from 2001 to 2007, and to determine the impact of diabetes on length of stay (LOS) and charges per day.

DESIGN

Longitudinal retrospective cohort analysis of inpatient rehabilitation discharge data from the Washington State Department of Health Comprehensive Hospital Abstract Reporting System.

SETTING

Inpatient rehabilitation.

PARTICIPANTS

Adults (N=56,382) who were discharged from inpatient rehabilitation in Washington State between 2001 and 2007.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Evidence of an established diagnosis of diabetes from International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnosis codes; comorbid conditions reported in ICD-9-CM codes; LOS; and charges per stay.

RESULTS

For all discharges from 2001 to 2007, diabetes prevalence was 17.8%; prevalence within specific impairment groups was 21.3% for the stroke subgroup, 14.2% for the orthopedic disorders subgroup, and 25% for the medically complex conditions subgroup. For all discharges, and within each impairment subgroup, prevalence did not change significantly from year to year. When adjusted for burden of nondiabetes comorbidities, LOS was significantly shorter for all discharges with diabetes younger than 65 years. The association between a diabetes codiagnosis and LOS in specific impairment groups was complex, ranging from a significantly shorter LOS for discharges with diabetes in the stroke subgroup to a finding of no significant difference in LOS among discharges with or without diabetes in the orthopedic impairments subgroup. Across all discharges, charges per day from 2003 to 2007 were significantly greater in discharges with diabetes. Within each specific impairment subgroup, charges per day across the entire study period were significantly greater for discharges with diabetes.

CONCLUSIONS

The high prevalence of diabetes, coupled with its impact on resource use, suggests that substantial pressures may be placed on the inpatient rehabilitation care system to respond to the needs of those with diabetes.
