The pre-adaptation of a stroke-specific self-management program among older adults.
To understand the management of multimorbidity in aging stroke survivors and to examine the complex relationships between comorbidities, researchers used visual analytics to identify patient subgroup. Five significant subgroups of comorbidities such as obesity and cancer were identified. An interdisciplinary team constructed six vignettes that highlighted multimorbidity to customize a self-management program that fitted the needs of older adult stroke survivors.

Initiation of oral anticoagulation in US older adults newly diagnosed with atrial fibrillation during hospitalization.
This study investigated prevalence of oral anticoagulant initiation for newly diagnosed US older adults with atrial fibrillation within 7 days of hospital discharge. The authors used a 20% national sample of Medicare fee-for-service beneficiaries, identifying patients aged 65 years or older newly diagnosed with atrial fibrillation while hospitalized in 2016. Among 38,379 older adults newly diagnosed with atrial fibrillation while hospitalized (mean age 78.2; 51.8% female; 83.3% white), 36,633 (95.4%) had an indication for anticoagulation and 24.6% (9011) of those initiated an oral anticoagulant following discharge. Higher CHA(2) DS(2) -VASc score was associated with a small increase in oral anticoagulant initiation (predicted probability 20.5% for scores <2 and 24.9% for ≥4). Elevated HAS-BLED score was associated with a small decrease in probability of anticoagulant initiation (25.4% for score <2 and 23.1% for ≥3). Frailty was associated with decreased likelihood of oral anticoagulant initiation (24.7% for non-frail and 18.1% for moderately-severely frail). Anticoagulant initiation varied by primary reason for hospitalization, with predicted probability highest among patients with a primary diagnosis of atrial fibrillation (46.1%) and lowest among those with non-cardiovascular conditions (13.8%) and bleeds (3.6%).

Post-acute care use patterns among hospital service areas by older adults in the United States: a cross-sectional study.
This study examined post-stroke acute care patterns across Hospital Service Areas among a national stroke cohort of Medicare beneficiaries to determine drivers of variation in post-acute care service utilization. Data was extracted from 2013 to 2014 (174,498 total records across 3232 Hospital Service Areas). Patients’ residence ZIP codes were linked to the facility ZIP code where care was received. Patients were considered a “traveler” if they did not live in the Hospital Service Area where they received care. Only 23.5% of all patients received care in skilled nursing-only Hospital Service Areas although 73.4% of all Hospital Service Areas were skilled nursing-only. Thirty-five percent of all patients traveled to a different Hospital Service Area from their residence. Patients living in skilled nursing-only Hospital Service Areas had more than 5 times the odds of traveling compared to those living in Hospital Service Areas with skilled nursing, inpatient rehabilitation, and long-term care hospital services.

The impact of one's sex and social living situation on rehabilitation outcomes after a stroke.
The goal of this retrospective observational study was to investigate sex differences and the impact of social living situation on individual functional independence measure outcomes after stroke rehabilitation. Subjects were Medicare fee-for-service beneficiaries discharged from inpatient rehabilitation facilities after a stroke. Results showed that when sociodemographic and clinical factors were controlled, females were more likely to discharge from inpatient rehabilitation at a supervision level or better for most functional independence measure items. Individuals who lived alone before their stroke had higher odds of discharging at a supervision level or better.

Role of diabetes and insulin use in the risk of stroke and acute myocardial infarction in patients with atrial fibrillation: a Medicare analysis.
This study examined the role of diabetes and insulin use in the risk of stroke and acute myocardial infarction (AMI) in patients with atrial fibrillation (AF). A cohort of Medicare beneficiaries newly diagnoses with AF from 2011 to 2013 were identified. The cohort was divided into those with diabetes requiring insulin (6.7%), those with diabetes not requiring insulin (31.3%) and non-diabetics (62%). Diabetics requiring insulin were at the greatest risk of stroke and AMI, and diabetics not requiring insulin were at slightly lower risk, but non-diabetics had the lowest risk.

Men lacking a caregiver have greater risk of long-term nursing home placement after stroke.
The purpose of this study was to understand how the availability of a caregiver can affect nursing home placement after ischemic stroke and how this affects different subgroups differently. The investigators found that in men aged 65 and older who have survived an ischemic stroke, the lack of an available caregiver is associated with triple the risk of NHP within 5 years.

Effect of race on outcomes (stroke and death) in patients >65 years with atrial fibrillation.
The researchers sought to determine whether there are any racial differences in the outcomes of death and stroke in patients with newly diagnosed AF in patients >65 years. They found that the risks of death and stroke are higher in blacks and Hispanics compared with whites. The increased risk was eliminated or significantly reduced after adjusting for preexisting co-morbidities.
