RESUMO

Falls are common in Assisted Living Facilities (ALFs). We evaluated the feasibility, acceptability, and preliminary impact of student-led Fall Prevention Care Management (FPCM) on reducing fall risks in ALFs. Residents who were age ≥65, had a fall in the previous year Or considered high fall risk at the facility, and who had a MoCA cognition score>15 were enrolled. The FPCM interventions were semi-structured to facilitate students' learning while addressing participants' unique fall risks. Twenty-five older adults in the U.S. completed the study (recruitment rate: 55%; retention rate: 64%). Participants rated the study as 87.16 (100 = excellent), and likelihood to recommend the study to others was 80.85 (100 = most likely). Participants were 84% female, mean age 88.6 years old. Fall risks such as fear of falling decreased from 16.05 to 15.12 (p = .022), fall prevention behaviors increased from 2.94 to 3.07 (p = .048), and the level of confidence to prevent falls increased from 63.38 to 78.35 (p = .015). Students commonly provided education and coaching on fall prevention strategies, and addressed emotional and behavioral aspects of fall prevention. With improvement with recruitment and retention, student-led FPCM intervention is a promising approach for fall prevention in ALF.

RESUMO

BACKGROUND: Disability in activities of daily living (ADLs) is a dynamic process and transitions among different disability states are common. However, little is known about factors affecting recovery from disability. We examined the association between frailty and recovery from disability among nondisabled community-dwelling elders. METHODS: We studied 1,023 adults from the Cardiovascular Health Study (CHS) and 685 adults from the Health and Retirement Study (HRS), who were ≥65 years and had incident disability, defined as having difficulty in ≥1 ADL (dressing, eating, toileting, bathing, transferring, walking across a room). Disability recovery was defined as having no difficulty in any ADLs. Frailty was assessed by slowness, weakness, exhaustion, inactivity, and shrinking. Persons were classified as "nonfrail" (0 criteria), "prefrail" (1-2 criteria), or "frail" (3-5 criteria). RESULTS: In total, 539 (52.7%) CHS participants recovered from disability within 1 year. Almost two-thirds of nonfrail persons recovered, while less than two-fifths of the frail recovered. In the HRS, 234 (34.2%) participants recovered from disability within 2 years. Approximately half of the nonfrail recovered, while less than one-fifth of the frail recovered. After adjustment, prefrail and frail CHS participants were 16% and 36% less likely to recover than the nonfrail, respectively. In the HRS, frail persons had a 41% lower likelihood of recovery than the nonfrail. CONCLUSIONS: Frailty is an independent predictor of poor recovery from disability among nondisabled older adults. These findings validate frailty as a marker of decreased resilience and may offer opportunities for individualized interventions and geriatric care based on frailty assessment.

RESUMO

OBJECTIVES: To identify a quick clinical tool to assess the risk of delirium after elective surgery. DESIGN: Prospective observational study. SETTING: Preoperative assessment clinic at the Veterans Affairs Portland Health Care System. PARTICIPANTS: Community-living veterans aged 65 and older scheduled for elective surgery requiring general or major anesthesia. MEASUREMENTS: Confusion Assessment Method (CAM) or Family Confusion Assessment Method (FAM-CAM). Data on education, medications, substance use, Patient Health Questionnaire (PHQ-9), Study of Osteoporotic Fractures Frailty, Mini-Cog, and Charlson-Deyo score were collected preoperatively. RESULTS: Of 114 veterans who agreed to participate, 76 completed the final delirium assessment. Ten of the 76 (13%) developed delirium in the 72 hours after surgery as assessed using the CAM or FAM-CAM. In bivariate analysis, factors that increased the odds of delirium at least three times were low education; poor PHQ-9, clock draw, word recall, Mini-Cog, and poor preoperative orientation scores; alcohol use; and higher comorbidities as measured using Charlson-Deyo index. Scoring the Mini-Cog from 0 to 5 had a higher predictive power (area under the receiving operating characteristic curve = 0.77) than other approaches to scoring the Mini-Cog. Other models did not significantly improve prediction of postoperative delirium risk and would be complicated to use in a clinical setting. CONCLUSION: In this sample of veterans who had elective surgery with major anesthesia, Mini-Cog score predicted likelihood of postoperative delirium.

RESUMO

OBJECTIVES: To characterize the pharmacy density in rural and urban communities with hospitals and to examine its association with readmission rates. DESIGN: Ecologic study. SETTING: Forty-eight rural and urban primary care service areas (PCSAs) in the state of Oregon. PARTICIPANTS: All hospitals in the state of Oregon. INTERVENTION: Pharmacy data were obtained from the Oregon Board of Pharmacy based on active licensure. Pharmacy density was calculated by determining the cumulative number of outpatient pharmacy hours in a PCSA. MAIN OUTCOME MEASURES: Oregon hospital 30-day all-cause readmission rates were obtained from the Centers for Medicare and Medicaid Services and were determined with the use of claims data of patients 65 years of age or older who were readmitted to the hospital within 30 days from July 2012 to June 2013. RESULTS: Readmission rates for Oregon hospitals ranged from 13.5% to 16.5%. The cumulative number of pharmacy hours in PCSAs containing a hospital ranged from 54 to 3821 hours. As pharmacy density increased, the readmission rates decreased, asymptotically approaching a predicted 14.7% readmission rate for areas with high pharmacy density. CONCLUSION: Urban hospitals were in communities likely to have more pharmacy access compared with rural hospitals. Future research should determine if increasing pharmacy access affects readmission rates, especially in rural communities.

RESUMO

BACKGROUND: HMG-CoA reductase inhibitors (statins) are among the most commonly prescribed classes of medications. Although their cardiovascular benefits and myalgia risks are well documented, their effects on older adults initiating an exercise training program are less understood. METHODS: 1,635 sedentary men and women aged 70-89 years with Short Physical Performance Battery (SPPB) score of 9 or below and were able to walk 400 m were randomized to a structured, moderate-intensity physical activity (PA) program consisting of both center-based (twice/wk) and home-based (3-4 times/wk) aerobic, resistance, and flexibility training or to a health education (HE) program combined with upper extremity stretching. RESULTS: Overall, the PA intervention was associated with lower risk of major mobility disability (hazard ratio [HR] = 0.82; 95% confidence interval [CI] = 0.69-0.98). The effect was similar (p value for interaction = .62) in both statin users (PA n = 415, HE n = 412; HR = 0.86, 95% CI = 0.67-1.1) and nonusers (PA n = 402, HE n = 404; HR = 0.78, 95% CI = 0.61-1.01). Attendance was similar for statin users (65%) and nonusers (63%). SPPB at 12 months was slightly greater for PA (8.35±0.10) than for HE (7.94±0.10) in statin users but not in nonusers (PA 8.25±0.10, HE 8.16±0.10), though the interaction effect was not statistically significant. Self-reported PA levels were not different between statin users and nonusers. CONCLUSIONS: Although statins have been associated with adverse effects on muscle, data from the LIFE Study show that statin users and nonusers both benefit from PA interventions. Older adults who require statin medications to manage chronic medical conditions and are sedentary will be able to benefit from interventions to increase PA.

RESUMO

PURPOSE: To characterize disease burden and medication usage in rural and urban adults aged ≥85 years. METHODS: This is a secondary analysis of 5 years of longitudinal data starting in the year 2000 from 3 brain-aging studies. Cohorts consisted of community-dwelling adults: 1 rural cohort, the Klamath Exceptional Aging Project (KEAP), was compared to 2 urban cohorts, the Oregon Brain Aging Study (OBAS) and the Dementia Prevention study (DPS). In this analysis, 121 participants were included from OBAS/DPS and 175 participants were included from KEAP. Eligibility was determined based on age ≥85 years and having at least 2 follow-up visits after the year 2000. Disease burden was measured by the Modified Cumulative Illness Rating Scale (MCIRS), with higher values representing more disease. Medication usage was measured by the estimated mean number of medications used by each cohort. FINDINGS: Rural participants had significantly higher disease burden as measured by MCIRS, 23.0 (95% CI: 22.3-23.6), than urban participants, 21.0 (95% CI: 20.2-21.7), at baseline. The rate of disease accumulation was a 0.2 increase in MCIRS per year (95% CI: 0.05-0.34) in the rural population. Rural participants used a higher mean number of medications, 5.5 (95% CI: 4.8-6.1), than urban participants, 3.7 (95% CI: 3.1-4.2), at baseline (P < .0001). CONCLUSIONS: These data suggest that rural and urban Oregonians aged ≥85 years may differ by disease burden and medication usage. Future research should identify opportunities to improve health care for older adults.

RESUMO

The nano-sized ß-tricalcium phosphate granules for the practical application of bone graft substitutes could be prepared from the wet chemically precipitated ß-TCP powders by the liquid-solid mixture route and by controlling the pH of mixture solution to 7.5 within a shorter processing time. The phase purity of prepared ß-TCP granules was higher above 99% and their particle sizes ranged from 200 to 650 nm. Also, their average compressive strength was higher at 2.22 MPa. It is considered that the phase purity, particle refinement, and mechanical compressive strength of ß-TCP granules could be significantly improved through the ß-TCP powders synthesized through the liquid-solid mixture precipitation at pH of 7.5. Meanwhile both the porosity and the specific surface area positively associated with the osteoconductivity for bone regeneration were higher at 75% and 2.50 m(2)/g respectively due to the nano-sized particles of porous ß-TCP granules. Furthermore, the histological analysis in beagle mandibular defect showed that ß-TCP granules demonstrated remarkable bone regeneration effect compared with that of the non-treatment group, indicating the increased new formation of bone (except for callus) (48.42 ± 6.57%) and rapid resorption (69.49 ± 2.40%) without toxicologically significant changes at 12 weeks after implantation.

RESUMO

BACKGROUND: Older adults frequently have several chronic health conditions which require multiple medications. We illustrated trends in prescription medication use over 20 years in the United States, and described characteristics of older adults using multiple medications in 2009-2010. METHODS: Participants included 13,869 adults aged 65 years and older in the National Health & Nutrition Examination Survey (1988-2010). Prescription medication use was verified by medication containers. Potentially inappropriate medications were defined by the 2003 Beers Criteria. RESULTS: Between 1988 and 2010 the median number of prescription medications used among adults aged 65 and older doubled from 2 to 4, and the proportion taking ≥5 medications tripled from 12.8% (95% confidence interval: 11.1, 14.8) to 39.0% (35.8, 42.3).These increases were driven, in part, by rising use of cardioprotective and antidepressant medications. Use of potentially inappropriate medications decreased from 28.2% (25.5, 31.0) to 15.1% (13.2, 17.3) between 1988 and 2010. Higher medication use was associated with higher prevalence of functional limitation, activities of daily living limitation, and confusion/memory problems in 2009-2010, although these associations did not remain after adjustment for covariates. In multivariable models, older age, number of chronic conditions, and annual health care visits were associated with increased odds of using both 1-4 and ≥5 medications. Additionally, body mass index, higher income-poverty ratio, former smoking, and non-black non-white race were associated with use of ≥5 medications. CONCLUSIONS: Prescription medication use increased dramatically among older adults between 1988 and 2010. Contemporary older adults on multiple medications have worse health status compared with those on less medications, and appear to be a vulnerable population.

RESUMO

BACKGROUND: Hypertension increases with increasing age. Optimal treatment of hypertension is important to reduce cardiovascular disease. Recent guidelines for hypertension have made recommendations for older adults but are supported by evidence that includes younger individuals. This systematic review evaluates the benefits and harms of antihypertensive agents in adults aged ≥65 years. METHODS: We searched MEDLINE and ClinicalTrials.gov for studies from 1996 to 2014. Eligible studies included participants aged ≥65 years with hypertension. Eligible studies had clearly defined treatment assignments, blood pressure (BP) targets, and evaluated endpoints of cardiovascular morbidity, mortality, and/or harms of antihypertensive medications. We abstracted study characteristics, cardiovascular benefits, and harms. RESULTS: Thirty-one articles met the inclusion criteria. Most studies compared different antihypertensive agents and/or placebo groups. These studies consistently demonstrated reduced cardiovascular morbidity and mortality compared with no treatment. Seven studies examined optimal BP targets. Strict control [systolic BP (SBP)<140 mmHg] was not consistently better than mild control (SBP<150 mmHg) for adults aged ≥65 years. Mild SBP control benefitted subjects in all age ranges over 65 years. Few studies assessed and explicitly reported harms. CONCLUSIONS: In this review, older adults with hypertension had decreased cardiovascular morbidity and mortality with antihypertensives compared with no treatment. Strict control was not consistently better than mild control in older adults. There was enormous heterogeneity in these studies, and reporting of harms stratified by age is lacking. The current evidence is insufficient to determine the safest, most beneficial hypertension regimen in older adults.

RESUMO

IMPORTANCE: Muscle pain, fatigue, and weakness are common adverse effects of statin medications and may decrease physical activity in older men. OBJECTIVE: To determine whether statin use is associated with physical activity, longitudinally and cross-sectionally. DESIGN, SETTING, AND PARTICIPANTS: Men participating in the Osteoporotic Fractures in Men Study (N = 5994), a multicenter prospective cohort study of community-living men 65 years and older, enrolled between March 2000 and April 2002. Follow-up was conducted through 2009. EXPOSURES: Statin use as determined by an inventory of medications (taken within the last 30 days). In cross-sectional analyses (n = 4137), statin use categories were users and nonusers. In longitudinal analyses (n = 3039), categories were prevalent users (baseline use and throughout the study), new users (initiated use during the study), and nonusers (never used). MAIN OUTCOMES AND MEASURES: Self-reported physical activity at baseline and 2 follow-up visits using the Physical Activity Scale for the Elderly (PASE). At the third visit, an accelerometer measured metabolic equivalents (METs [kilocalories per kilogram per hour]) and minutes of moderate activity (METs ≥3.0), vigorous activity (METs ≥6.0), and sedentary behavior (METs ≤1.5). RESULTS: At baseline, 989 men (24%) were users and 3148 (76%) were nonusers. The adjusted difference in baseline PASE between users and nonusers was -5.8 points (95% CI, -10.9 to -0.7 points). A total of 3039 men met the inclusion criteria for longitudinal analysis: 727 (24%) prevalent users, 845 (28%) new users, and 1467 (48%) nonusers. PASE score declined by a mean (95% CI) of 2.5 (2.0 to 3.0) points per year for nonusers and 2.8 (2.1 to 3.5) points per year for prevalent users, a nonstatistical difference (0.3 [-0.5 to 1.0] points). For new users, annual PASE score declined at a faster rate than nonusers (difference of 0.9 [95% CI, 0.1 to 1.7] points). A total of 3071 men had adequate accelerometry data, 1542 (50%) were statin users. Statin users expended less METs (0.03 [95% CI, 0.02-0.04] METs less) and engaged in less moderate physical activity (5.4 [95% CI, 1.9-8.8] fewer minutes per day), less vigorous activity (0.6 [95% CI, 0.1-1.1] fewer minutes per day), and more sedentary behavior (7.6 [95% CI, 2.6-12.4] greater minutes per day). CONCLUSIONS AND RELEVANCE: Statin use was associated with modestly lower physical activity among community-living men, even after accounting for medical history and other potentially confounding factors. The clinical significance of these findings deserves further investigation.

RESUMO

IMPORTANCE: Randomized trials of anti-hypertensive treatment demonstrating reduced risk of cardiovascular events in older adults included participants with less comorbidity than clinical populations. Whether these results generalize to all older adults, most of whom have multiple chronic conditions, is uncertain. OBJECTIVE: To determine the association between anti-hypertensive medications and CV events and mortality in a nationally representative population of older adults. DESIGN: Competing risk analysis with propensity score adjustment and matching in the Medicare Current Beneficiary Survey cohort over three-year follow-up through 2010. PARTICIPANTS AND SETTING: 4,961 community-living participants with hypertension. EXPOSURE: Anti-hypertensive medication intensity, based on standardized daily dose for each anti-hypertensive medication class participants used. MAIN OUTCOMES AND MEASURES: Cardiovascular events (myocardial infarction, unstable angina, cardiac revascularization, stroke, and hospitalizations for heart failure) and mortality. RESULTS: Of 4,961 participants, 14.1% received no anti-hypertensives; 54.6% received moderate, and 31.3% received high, anti-hypertensive intensity. During follow-up, 1,247 participants (25.1%) experienced cardiovascular events; 837 participants (16.9%) died. Of deaths, 430 (51.4%) occurred in participants who experienced cardiovascular events during follow-up. In the propensity score adjusted cohort, after adjusting for propensity score and other covariates, neither moderate (adjusted hazard ratio, 1.08 [95% CI, 0.89-1.32]) nor high (1.16 [0.94-1.43]) anti-hypertensive intensity was associated with experiencing cardiovascular events. The hazard ratio for death among all participants was 0.79 [0.65-0.97] in the moderate, and 0.72 [0.58-0.91] in the high intensity groups compared with those receiving no anti-hypertensives. Among participants who experienced cardiovascular events, the hazard ratio for death was 0.65 [0.48-0.87] and 0.58 [0.42-0.80] in the moderate and high intensity groups, respectively. Results were similar in the propensity score-matched subcohort. CONCLUSIONS AND RELEVANCE: In this nationally representative cohort of older adults, anti-hypertensive treatment was associated with reduced mortality but not cardiovascular events. Whether RCT results generalize to older adults with multiple chronic conditions remains uncertain.

RESUMO

OBJECTIVE: The 75% of older adults with multiple chronic conditions are at risk of therapeutic competition (i.e. treatment for one condition may adversely affect a coexisting condition). The objective was to determine the prevalence of potential therapeutic competition in community-living older adults. METHODS: Cross-sectional descriptive study of a representative sample of 5,815 community-living adults 65 and older in the U.S, enrolled 2007-2009. The 14 most common chronic conditions treated with at least one medication were ascertained from Medicare claims. Medication classes recommended in national disease guidelines for these conditions and used by ≥ 2% of participants were identified from in-person interviews conducted 2008-2010. Criteria for potential therapeutic competition included: 1), well-acknowledged adverse medication effect; 2) mention in disease guidelines; or 3) report in a systematic review or two studies published since 2000. Outcomes included prevalence of situations of potential therapeutic competition and frequency of use of the medication in individuals with and without the competing condition. RESULTS: Of 27 medication classes, 15 (55.5%) recommended for one study condition may adversely affect other study conditions. Among 91 possible pairs of study chronic conditions, 25 (27.5%) have at least one potential therapeutic competition. Among participants, 1,313 (22.6%) received at least one medication that may worsen a coexisting condition; 753 (13%) had multiple pairs of such competing conditions. For example, among 846 participants with hypertension and COPD, 16.2% used a nonselective beta-blocker. In only 6 of 37 cases (16.2%) of potential therapeutic competition were those with the competing condition less likely to receive the medication than those without the competing condition. CONCLUSIONS: One fifth of older Americans receive medications that may adversely affect coexisting conditions. Determining clinical outcomes in these situations is a research and clinical priority. Effects on coexisting conditions should be considered when prescribing medications.

RESUMO

IMPORTANCE The effect of serious injuries, such as hip fracture and head injury, on mortality and function is comparable to that of cardiovascular events. Concerns have been raised about the risk of fall injuries in older adults taking antihypertensive medications. The low risk of fall injuries reported in clinical trials of healthy older adults may not reflect the risk in older adults with multiple chronic conditions. OBJECTIVE To determine whether antihypertensive medication use was associated with experiencing a serious fall injury in a nationally representative sample of older adults. DESIGN, PARTICIPANTS, AND SETTING Competing risk analysis as performed with propensity score adjustment and matching in the nationally representative Medicare Current Beneficiary Survey cohort during a 3-year follow-up through 2009. Participants included 4961 community-living adults older than 70 years with hypertension. EXPOSURES Antihypertensive medication intensity based on the standardized daily dose for each antihypertensive medication class that participants used. MAIN OUTCOMES AND MEASURES Serious fall injuries, including hip and other major fractures, traumatic brain injuries, and joint dislocations, ascertained through Centers for Medicare & Medicaid Services claims. RESULTS Of the 4961 participants, 14.1% received no antihypertensive medications; 54.6% were in the moderate-intensity and 31.3% in the high-intensity antihypertensive groups. During follow-up, 446 participants (9.0%) experienced serious fall injuries, and 837 (16.9%) died. The adjusted hazard ratios for serious fall injury were 1.40 (95% CI, 1.03-1.90) in the moderate-intensity and 1.28 (95% CI, 0.91-1.80) in the high-intensity antihypertensive groups compared with nonusers. Although the difference in adjusted hazard ratios across the groups did not reach statistical significance, results were similar in the propensity score-matched subcohort. Among 503 participants with a previous fall injury, the adjusted hazard ratios were 2.17 (95% CI, 0.98-4.80) for the moderate-intensity and 2.31 (95% CI, 1.01-5.29) for the high-intensity antihypertensive groups. CONCLUSIONS AND RELEVANCE Antihypertensive medications were associated with an increased risk of serious fall injuries, particularly among those with previous fall injuries. The potential harms vs benefits of antihypertensive medications should be weighed in deciding to continue treatment with antihypertensive medications in older adults with multiple chronic conditions.

RESUMO

CONTEXT: In older adults with multiple conditions, medications may not impart the same benefits seen in patients who are younger or without multimorbidity. Furthermore, medications given for one condition may adversely affect other outcomes. ß-Blocker use with coexisting cardiovascular disease (CVD) and chronic obstructive pulmonary disease (COPD) is such a situation. OBJECTIVE: To determine the effect of ß-blocker use on cardiac and pulmonary outcomes and mortality in older adults with coexisting COPD and CVD. DESIGN, SETTING, PARTICIPANTS: The study included 1062 participants who were members of the 2004-2007 Medicare Current Beneficiary Survey cohorts, a nationally representative sample of Medicare beneficiaries. Study criteria included age over 65 years plus coexisting CVD and COPD/asthma. Follow-up occurred through 2009. We determined the association between ß-blocker use and the outcomes with propensity score-adjusted and covariate-adjusted Cox proportional hazards. MAIN OUTCOME MEASURES: The 3 outcomes were major cardiac events, pulmonary events, and all-cause mortality. RESULTS: Half of the participants used ß-blockers. During follow-up, 179 participants experienced a major cardiac event; 389 participants experienced a major pulmonary event; and 255 participants died. Each participant could have experienced any ≥1 of these events. The hazard ratio for ß-blocker use was 1.18 [95% confidence interval (CI), 0.85-1.62] for cardiac events, 0.91 (95% CI, 0.73-1.12) for pulmonary events, and 0.87 (95% CI, 0.67-1.13) for death. CONCLUSION: In this population of older adults, ß-blockers did not seem to affect occurrence of cardiac or pulmonary events or death in those with CVD and COPD.

RESUMO

BACKGROUND: Patients with dementia constitute an increasing proportion of hospice enrollees, yet little is known about the quality of hospice care for this population. The aim of this study was to quantify differences in quality of care measures between hospice patients with and without dementia. DESIGN: Cross-sectional analysis of data. SETTING: 2007 National Home and Hospice Care Survey. PARTICIPANTS: Four thousand seven hundred eleven discharges from hospice care. MEASUREMENTS: A primary diagnosis of dementia at discharge was defined according to International Classification of Diseases, Ninth Revision, codes (290.0-290.4x, 294.0, 294.1, 294.8, 331.0-331.2, 331.7, and 331.8). Quality-of-care measures included enrollment in hospice in the last 3 days of life, receiving tube feeding, depression, receiving antibiotics, lack of advanced directive or do not resuscitate order, Stage II or greater pressure ulcers, emergency care, lack of continuity of residence, and a report of pain at last assessment. RESULTS: Four hundred fifty (9.5%) individuals were discharged with a primary diagnosis of dementia. In multivariable analysis, individuals with dementia were more likely to receive tube feeding (odds ratio (OR) = 2.6, 95% confidence interval (CI) = 1.4-4.5) and to have greater continuity of residence (OR = 1.8, 95% CI = 1.1-3.0) than other individuals in hospice and less likely to have a report of pain at last assessment (OR = 0.6, 95% CI = 0.3-0.9). CONCLUSIONS: The majority of quality-of-care measures examined did not differ between individuals in hospice with and without dementia. Use of tube feeding in hospice care and methods of pain assessment and treatment in individuals with dementia should be considered as potential quality-of-care measures.
