Project description:Objective/Background: We examined the rates, predictors, and outcomes [mortality risk (MR), length of stay (LOS), and total charges (TC)] of sleep disturbances in older hospitalized patients. Patients/Methods: Using the U.S. Nationwide Inpatient Sample database (2002-2012), older patients (?60 years) were selected and rates of insomnia, obstructive sleep apnea (OSA) and other sleep disturbances (OSD) were estimated using ICD-9CM. TC, adjusted for inflation, was of primary interest, while MR and LOS were secondary outcomes. Multivariable regression analyses were conducted. Results: Of 35,258,031 older adults, 263,865 (0.75%) had insomnia, 750,851 (2.13%) OSA and 21,814 (0.06%) OSD. Insomnia rates increased significantly (0.27% in 2002 to 1.29 in 2012, P-trend < 0.001), with a similar trend observed for OSA (1.47 in 2006 to 5.01 in 2012, P-trend < 0.001). TC (2012 $) for insomnia-related hospital admission increased over time from $22,250 in 2002 to $31,527 in 2012, and increased similarly for OSA and OSD; while LOS and MR both decreased. Women with any sleep disturbance had lower MR and TC than men, while Whites had consistently higher odds of insomnia, OSA, and OSD than older Blacks and Hispanics. Co-morbidities such as depression, cardiovascular risk factors, and neurological disorders steadily increased over time in patients with sleep disturbances. Conclusion: TC increased over time in patients with sleep disturbances while LOS and MR decreased. Further, research should focus on identifying the mechanisms that explain the association between increasing sleep disturbance rates and expenditures within hospital settings and the potential hospital expenditures of unrecognized sleep disturbances in the elderly.

Project description:In the inpatient setting, prevalence, predictors, and outcomes [mortality risk (MR), length of stay (LOS), and total charges (TC)] of Alzheimer's disease (AD) are largely unknown. We used data on older adults (60+ y) from the Nationwide Inpatient Sample (NIS) 2002-2012. AD prevalence was ∼3.12% in 2012 (total weighted discharges with AD ± standard error: 474, 410 ± 6,276). Co-morbidities prevailing more in AD inpatient admissions included depression (OR = 1.67, 95% CI: 1.63-1.71, p < 0.001), fluid/electrolyte disorders (OR = 1.25, 95% CI: 1.22-1.27, p < 0.001), weight loss (OR = 1.26, 95% CI: 1.22-1.30, p < 0.001), and psychosis (OR = 2.59, 95% CI: 2.47-2.71, p < 0.001), with mean total co-morbidities increasing over time. AD was linked to higher MR and longer LOS, but lower TC. TC rose in AD, while MR and LOS dropped markedly over time. In AD, co-morbidities predicting simultaneously higher MR, TC, and LOS (2012) included congestive heart failure, chronic pulmonary disease, coagulopathy, fluid/electrolyte disorders, metastatic cancer, paralysis, pulmonary circulatory disorders, and weight loss. In sum, co-morbidities and TC increased over time in AD, while MR and LOS dropped. Few co-morbidities predicted occurrence of AD or adverse outcomes in AD.

Project description:ObjectiveThis study aimed to identify temporal time trends and risk factors associated with mortality for hospitalized older adults with status epilepticus (SE).DesignA retrospective study was performed.SettingHospitalized patients were identified utilizing an administrative database-The Nationwide Inpatient Sample database from 1998 through September 2015.PatientsPatients were older adults 65 years and older with SE.InterventionsNo interventions were undertaken.Measurements and main resultsDemographic, temporal trends, clinical characteristics, and outcome data were abstracted. The results indicated that hospitalized elderly Americans with SE increased over the 11-year study period. Univariate and multivariate analyses were performed to evaluate risk factors associated with mortality in the study cohort. From the weighted sample, 130,109 subjects were included. Overall mortality was 19%. For age subgroups, the mortality was highest for the >85 years age group (24.1%) compared to the 65-75 years (19%) and 75-85 years (23%) age groups. Among investigated etiologies, the three most common causes of SE were acute ischemic stroke (11.2% of total) followed by non-traumatic brain hemorrhage (5.4%) and malignant brain lesions (4.9%). The highest mortality by etiology was noted for acute traumatic brain injury (TBI) (31.5%), non-traumatic brain hemorrhage (31%), and acute ischemic stroke (AIS) (30.1%). Multivariate analysis indicated that non-survivors when compared to survivors were more like to have the following characteristics: older age group, acute TBI, brain neoplasms, non-traumatic brain hemorrhage, AIS and central nervous system (CNS) infections, and utilization of mechanical ventilation. Associated conditions significantly increasing risk of mortality were sodium imbalance, cardiac arrest, anoxic brain injury, pneumonia, and sepsis. Comorbidities associated with increased risk of mortality included valvular heart disease, renal failure, liver disease, and neoplasms.ConclusionsThe number of hospitalized elderly Americans with SE increased over the 11-year study period. Overall mortality was 19%, with even higher mortality among various patient subsets. Several demographic and co-morbid factors are associated with increased mortality in this age group.

Project description:To determine the difference in receipt of activity of daily living (ADL) assistance between obese and normal-weight older adults.Retrospective cohort study.National Health and Aging Trends Study, 2011-2015.U.S. adults aged 65 and older with ADL disability and a body mass index (BMI) of 18.5 kg/m2 or greater (N = 5,612) MEASUREMENTS: BMI was classified as normal weight (18.5-24.9 kg/m2 ), overweight (25.0-29.9 kg/m2 ), or obese (?30.0 kg/m2 ). Primary outcome was self-reported receipt of help with specific ADLs. Models were adjusted for demographic characteristics (age, sex, race), degree of need (self-reported general health, severity of disability), household resources (income, marriage, people in household, number of children), and cognitive status (dementia, proxy respondent).Obese with disabilities had lower rates of receiving assistance with walking inside (odds ratio (OR) = 0.63, 95% confidence interval (CI) = 0.50-0.81), walking outside (OR = 0.76, 95% CI = 0.59-0.97), toileting (OR = 0.68, 95% CI = 0.52-0.89), and getting in and out of bed (OR = 0.67, 95% CI = 0.50-0.87) than normal-weight older adults after adjustment for respondent demographic characteristics. Level of need and cognitive status partially explained the associations. In fully adjusted models, older adults with obesity still had significantly lower odds of receiving assistance in getting in and out of bed than normal weight adults (OR = 0.69, 95% CI = 0.49-0.98).Older adults with obesity are less likely to receive assistance for ADL disabilities than their normal-weight counterparts-an important concern because of ongoing demographic changes in the United States.

Project description:OBJECTIVES:To determine whether there may be a common mechanism resulting in global sensory impairment of the five classical senses (vision, smell, hearing, touch, and taste) in older adults. DESIGN:Representative, population-based study. SETTING:National Social Life, Health, and Aging Project. PARTICIPANTS:Community-dwelling U.S. adults aged 57 to 85. MEASUREMENTS:The frequency with which impairment co-occurred across the five senses was estimated as an integrated measure of sensory aging. It was hypothesized that multisensory deficits would be common and reflect global sensory impairment that would largely explain the effects of age, sex, and race on sensory dysfunction. RESULTS:Two-thirds of subjects had two or more sensory deficits, 27% had just one, and 6% had none. Seventy-four percent had impairment in taste, 70% in touch, 22% in smell, 20% in corrected vision, and 18% in corrected hearing. Older adults, men, African Americans, and Hispanics had greater multisensory impairment (all P < .01). Global sensory impairment largely accounted for the effects of age, sex, and race on the likelihood of impairment in each of the five senses. CONCLUSION:Multisensory impairment is prevalent in older U.S. adults. These data support the concept of a common process that underlies sensory aging across the five senses. Clinicians assessing individuals with a sensory deficit should consider further evaluation for additional co-occurring sensory deficits.

Project description:OBJECTIVES:To determine the prevalence and impact of common co-occurring symptoms among community-dwelling older adults in the United States. DESIGN:The National Health and Aging Trends Study is a nationally representative, prospective study with annual data collection between 2011 and 2017. SETTING:Community-based, in-person interviews (survey response rates, 71%-96%). PARTICIPANTS:A total of 7,609 community-dwelling Medicare beneficiaries, 65 years or older. MEASUREMENTS:Symptoms assessed at baseline include pain, fatigue, breathing difficulty, sleeping difficulty, depressed mood, and anxiety. Total symptom count ranged from zero to six. Several outcomes were examined, including grip strength, gait speed, and overall lower-extremity function as well as incidence of recurrent falls (two or more per year), hospitalization, disability, nursing home admission, and mortality. RESULTS:Prevalence of zero, one, two, three, and four or more symptoms was 25.0%, 26.6%, 20.7%, 14.0%, and 13.6%, respectively. Symptom count increased with advancing age and was higher in women than in men. Pain and fatigue were the most common co-occurring symptoms. Higher symptom count was associated with decreased physical capacity. For example, participants with one, two, three, and four or more symptoms had gait speeds that were 0.04, 0.06, 0.09, and 0.13 m/s slower, respectively, than those with no symptoms, adjusting for specific diseases, total number of diseases, and other potential confounders (P < .001). The risk of several adverse outcomes also increased with greater symptom count. For example, compared with those with no symptoms, the adjusted risk ratios for recurrent falls were 1.48 (95% confidence interval [CI] = 1.30-1.70), 1.54 (95% CI = 1.32-1.80), 1.90 (95% CI = 1.55-2.32), and 2.38 (95% CI = 2.00-2.83) for older adults with one, two, three, and four or more symptoms, respectively. CONCLUSIONS:Symptoms frequently co-occur among community-dwelling older adults and are strongly associated with increased risk of a range of adverse outcomes. Symptoms represent a potential treatment target for improving outcomes and should be systematically captured in health records. J Am Geriatr Soc 67:223-231, 2019.

Project description:BackgroundIn a nationally representative sample of United States Medicare beneficiaries, we examined the extent of chiropractic use, factors associated with seeing a chiropractor, and predictors of the volume of chiropractic use among those having seen one.MethodsWe performed secondary analyses of baseline interview data on 4,310 self-respondents who were 70 years old or older when they first participated in the Survey on Assets and Health Dynamics Among the Oldest Old (AHEAD). The interview data were then linked to their Medicare claims. Multiple logistic and negative binomial regressions were used.ResultsThe average annual rate of chiropractic use was 4.6%. During the four-year period (two years before and two years after each respondent's baseline interview), 10.3% had one or more visits to a chiropractor. African Americans and Hispanics, as well as those with multiple depressive symptoms and those who lived in counties with lower than average supplies of chiropractors were much less likely to use them. The use of chiropractors was much more likely among those who drank alcohol, had arthritis, reported pain, and were able to drive. Chiropractic services did not substitute for physician visits. Among those who had seen a chiropractor, the volume of chiropractic visits was lower for those who lived alone, had lower incomes, and poorer cognitive abilities, while it was greater for the overweight and those with lower body limitations.ConclusionChiropractic use among older adults is less prevalent than has been consistently reported for the United States as a whole, and is most common among Whites, those reporting pain, and those with geographic, financial, and transportation access.

Project description:Studies of dialysis initiation timing have not accounted for predialysis clinical factors that could impact postdialysis outcomes. We examined the association of predialysis health with timing of dialysis initiation in older adult patients in the United States and contrasted morbidity and mortality outcomes among patients with early [estimated GFR (eGFR)?10 ml/min per 1.73 m(2)] versus later (eGFR<10 ml/min per 1.73 m(2)) initiation. We included all patients from the US Renal Data System who initiated dialysis between 2006 and 2008, were ?67 years old, and had ?2 years of prior Medicare coverage (n=84,654). We calculated patients' propensity to initiate dialysis early and matched patients by propensity scores. Cox models were used to compare risks of mortality and hospitalization among initiation groups. The majority (58%) of patients initiated dialysis early. Early initiators were more likely to have had AKI, multiple congestive heart failure admissions, and other hospitalizations preceding initiation. Among propensity-matched patients (n=61,930), early initiation associated with greater all-cause (hazard ratio [HR], 1.11; 95% confidence interval [95% CI], 1.08 to 1.14), cardiovascular (CV; HR, 1.13; 95% CI, 1.09 to 1.17), and infectious (HR, 1.13; 95% CI, 1.06 to 1.22) mortality and greater all-cause (HR, 1.03; 95% CI, 1.01 to 1.05) and infectious (HR, 1.10; 95% CI, 1.07 to 1.13) hospitalizations. There was no difference in CV hospitalizations. Among these older adults, early dialysis initiation associates with greater mortality and hospitalizations, even after accounting for predialysis clinical factors. These findings do not support the common practice of early dialysis initiation in the United States.

Project description:ObjectivesEmergency preparedness becomes more important with increased age, as older adults are at heightened risk for harm from disasters. In this study, predictors of preparedness actions and confidence in preparedness among older adults in the United States were assessed.MethodsThis nationally representative survey polled community-dwelling older adults ages 50-80 y (n = 2256) about emergency preparedness and confidence in addressing different types of emergencies. Logistic regression was used to identify predictors of reported emergency preparedness actions and confidence in addressing emergencies.ResultsParticipants' mean age was 62.4 y (SD = 8); 52% were female, and 71% were non-Hispanic white. Living alone was associated with lower odds of having a 7-d supply of food and water (adjusted odds ratio [aOR] = 0.74; 95% confidence interval [CI]: 0.56-0.96), a stocked emergency kit (aOR = 0.64; 95% CI: 0.47-0.86), and having had conversations with family or friends about evacuation plans (aOR = 0.59; 95% CI: 0.44-0.78). Use of equipment requiring electricity was associated with less confidence in addressing a power outage lasting more than 24 h (aOR = 0.66; 95% CI: 0.47-0.94), as was use of mobility aids (OR = 0.65; 95% CI: 0.45-0.93).ConclusionsThese results point to the need for tailored interventions to support emergency preparedness for older adults, particularly among those who live alone and use medical equipment requiring electricity.

Project description:BackgroundPrevious studies have suggested that hearing loss, which is highly prevalent but undertreated in older adults, may be associated with gait and physical functioning. Determining if hearing loss is independently associated with gait speed is critical toward understanding whether hearing rehabilitative interventions could help mitigate declines in physical functioning in older adults.MethodsWe analyzed cross-sectional data from the 1999 to 2002 cycles of the National Health and Nutritional Examination Survey during which participants 50-69 years (n=1180) underwent hearing and gait speed assessments. Hearing was defined by a pure tone average of hearing thresholds at 0.5-4kHz tones in the better-hearing ear. Gait speed was obtained in a timed 20-ft (6.1m) walk. Linear and logistic regression models were used to examine the association between hearing loss and gait speed while adjusting for demographic and cardiovascular risk factors. Analyses incorporated sampling weights to yield results generalizable to the U.S. population.ResultsIn a model adjusted for demographic and cardiovascular risk factors, a hearing loss was associated with slower gait speed (-0.05m/s per 25dB of hearing loss [95% CI: -0.09 to -0.02]) and an increased odds of having a gait speed <1.0m/s (OR=2.0 per 25dB of hearing loss, 95% CI: 1.2-3.3). The reduction in gait speed associated with a 25dB hearing loss was equivalent to that associated with an age difference of approximately 12 years.ConclusionsGreater hearing loss is independently associated with slower gait speed. Further studies investigating the mechanistic basis of this association and whether hearing rehabilitative interventions could affect gait and physical functioning are needed.
