      &lt;p&gt;Older stroke patients remain at higher risk for adverse outcomes than younger ones, but the gap has narrowed with wider implementation of evidence-based guidelines, researchers say.&lt;/p&gt;
&lt;p&gt;More than 10% of stroke patients over 80 died in the hospital, compared with 3% of those under age 50, Gregg C. Fonarow, MD, of the University of California Los Angeles, and colleagues reported online in &lt;em&gt;Circulation&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;But overall use of guideline-recommended therapies improved substantially in older patients from 2003 to 2009, particularly for patients over 90, they said.&lt;/p&gt;
&lt;p&gt;During that time, several hospitals and stroke centers have adopted &quot;Get with the Guidelines,&quot; an intervention to apply evidence-based guidelines to care. Adopters have seen &quot;substantial improvements ... in performance measures for ischemic stroke patients, including pharmacological and nonpharmacological management in each age group,&quot; the researchers wrote.&lt;/p&gt;
&lt;p&gt;Before launching the initiative in 2003, studies generally showed lower use of guideline-recommended therapy and worse outcomes in older stroke patients.&lt;/p&gt;
&lt;p&gt;To assess changes since initiative started, the researchers analyzed more than 502,036 ischemic stroke admissions to 1,256 hospitals participating in the guidelines program between 2003 and 2009. Mean patient age was 71, and 52.5% were women.&lt;/p&gt;
&lt;p&gt;They found that performance on most evidence-based measures was lower in older patients  --  those ages 80 and up  --  compared with younger patients.&lt;/p&gt;
&lt;p&gt;The largest differences were seen in the proportion of eligible patients who received intravenous tissue plasminogen activator (tPA) treatments (51.1% for older patients versus 61.6% for those under 50, &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;Providers were also less likely to treat older stroke patients with lipid-lowering therapies than younger patients (54.2% versus 71.7%, &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;The smallest differences involved antithrombotic therapy within 48 hours of admission and at discharge.&lt;/p&gt;
&lt;p&gt;In terms of outcomes, older patients had a significantly higher inhospital mortality rate (10.3% versus 3%), and they were less likely to be discharged home. Rather, they were more likely to be discharged to a skilled nursing facility (42.1% versus 5.3%, &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001) or hospice (12% versus 0.5%, &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;With each 10-year age increase, patients with ischemic stroke were 31% less likely to be discharged home and 27% more likely to die in the hospital.&lt;/p&gt;
&lt;p&gt;But the researchers said that, generally, the use of guideline-recommended therapies improved substantially in older patients from 2003 to 2009.&lt;/p&gt;
&lt;p&gt;In those ages 90 and older, use of intravenous tPA increased threefold, from 20.4% in 2003 to 62.4% in 2009. And use of lipid lowering therapy increased from 15.6% in 2003 to 71.7%.&lt;/p&gt;
&lt;p&gt;The researchers wrote that by 2009, &quot;many of the age-related differences in care had narrowed or were eliminated.&quot;&lt;/p&gt;
&lt;p&gt;They cautioned, however, that there could be residual confounding by unmeasured factors. For example, physicians may be uncertain about risks versus benefits in treating older patients who are under-represented in RCTs.&lt;/p&gt;
&lt;p&gt;The authors noted that their study was limited by its reliance on the accuracy and completeness of medical records.&lt;/p&gt;
&lt;p&gt;Also, they noted, the &quot;Get with the Guidelines&quot; program tends to attract larger teaching hospitals, which already have a &quot;strong interest in stroke care and quality improvement,&quot; and thus the findings may not be generalizable.&lt;/p&gt;

                     score="0.005"
                     href="http://www.medpagetoday.com/Cardiology/CHF/tb/18193?impressionId=1265787846064"
                     
      &lt;p&gt;Serial measurement of a natriuretic peptide predicted the risk of heart failure and cardiovascular death in older patients who were initially free of heart failure, data from a longitudinal cohort study showed.&lt;/p&gt;
&lt;p&gt;An increase of more than 25% in levels of N-terminal pro-B type natriuretic peptide (NT-proBNP) doubled the risk of heart failure and cardiovascular death. In contrast, a more than 25% decrease in NT-proBNP was associated with a greater than 40% reduction in the risk of both end points.&lt;/p&gt;
&lt;p&gt;&quot;NT-proBNP levels frequently change over time, and these fluctuations reflect dynamic changes in cardiovascular risk,&quot; Christopher R. deFilippi, MD, of the University of Maryland in Baltimore, and co-authors concluded in an article in the Feb. 2 issue of the &lt;em&gt;Journal of the American College of Cardiology&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;&quot;This change in [NT-proBNP] level reflects a significant change in patient risk independent of cardiovascular risk factors, ejection fraction, or medication use,&quot; they added. &quot;Ultimately, NT-proBNP levels may guide further diagnostic testing or potential preventive measures to reduce the risk of developing heart failure or dying of cardiovascular disease.&quot;&lt;/p&gt;
&lt;p&gt;About 80% of cardiovascular deaths occur in older adults. Assessing cardiovascular risk in older patients is challenging because traditional cardiovascular risk factors are less predictive in older versus middle-age populations, the authors wrote.&lt;/p&gt;
&lt;p&gt;Subclinical cardiovascular disease is common among older adults and increases the risk of cardiovascular events, including heart failure. Repeated measures of traditional markers of cardiovascular disease in patients with subclinical disease are associated with increased risk compared with patients who remain free of identifiable disease, the authors continued.&lt;/p&gt;
&lt;p&gt;Levels of BNP and NT-proBNP are associated with long-term cardiovascular outcomes in the general population. However, the peptides&apos; ability to provide additional prognostic information beyond that of traditional risk factors remained controversial.&lt;/p&gt;
&lt;p&gt;To examine the prognostic value of NT-proBNP in an older population, deFilippi and colleagues analyzed data on 3,000 participants in the Cardiovascular Health Study. The authors hypothesized that NT-proBNP levels in an ambulatory population of older patients would independently predict new-onset heart failure and cardiovascular death.&lt;/p&gt;
&lt;p&gt;&quot;Furthermore, we anticipated that serial measurements of NT-proBNP, as a possible surrogate for change in subclinical disease status, identify a dynamic change in long-term risk of incident heart failure and cardiovascular mortality,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;Stored serum samples obtained at enrollment and two to three years later were used to measure NT-proBNP levels. Median follow-up for the cohort was 11.9 years.&lt;/p&gt;
&lt;p&gt;After separating the study group into quintiles of NT-proBNP levels, investigators found that patients with the highest baseline levels of the peptide (&amp;gt;267.7 pg/mL) had a threefold greater risk of new-onset heart failure (HR 3.05, 95% CI 2.46 to 3.78) and cardiovascular death (HR 3.02, 95% CI 2.36 to 3.86) compared with patients in the lowest NT-proBNP quintile (&amp;lt;47.5 pg/mL).&lt;/p&gt;
&lt;p&gt;The researchers identified 190 pg/mL as the NT-proBNP threshold for increased risk. Among study participants with baseline levels less than 190 pg/mL, an increase greater than 25% to a level above 190 pg/mL had a twofold increased risk of heart failure (HR 2.13, 95% CI 1.68 to 2.71) and cardiovascular death (HR 1.91, 95% CI 1.43 to 2.53) compared with participants whose NT-proBNP levels remained below 190 pg/mL.&lt;/p&gt;
&lt;p&gt;Among study participants with elevated baseline NT-proBNP levels, an increase greater than 25% also doubled the risk of heart failure (HR 2.06, 95% CI 1.56 to 2.72) and cardiovascular disease (HR 1.88, 95% CI 1.37 to 2.57).&lt;/p&gt;
&lt;p&gt;A decrease greater than 25% from baseline significantly reduced the risk of heart failure (HR 0.58, 95% CI 0.36 to 0.93) and cardiovascular death (HR 0.57, 95% CI 0.32 to 1.01) compared with participants whose baseline levels remained elevated.&lt;/p&gt;
&lt;p&gt;The investigators noted limitations of the study including the fact that a quarter of the participants did not have a follow-up blood sample and those who did were younger and had fewer cardiac risk factors.&lt;/p&gt;
&lt;p&gt;In addition, the length of follow-up could not account for differences in treatment over time, and the accuracy of NT-proBNP levels in samples as much as 20 years old cannot be assured.&lt;/p&gt;
&lt;p&gt;The study is noteworthy for highlighting the concept of dynamic risk assessment based on serial measurement of NT-proBNP, Richard W. Troughton, MB ChB, PhD, Matthew G. Daly, MB ChB, and Christopher M. Frampton, PhD, of the University of Otago in Christchurch, New Zealand, wrote in an editorial.&lt;/p&gt;
&lt;p&gt;&quot;The findings confirm a modest improvement in risk stratification by including a single measurement of NT-proBNP levels,&quot; they wrote &quot;The investigators take this a step further by showing that serial NT-proBNP measurement at a later time provides a further modest improvement in risk stratification.&quot;&lt;/p&gt;
&lt;p&gt;&quot;Whether the improvement in risk stratification achieved by performing serial NT-proBNP testing crosses a threshold of definite clinical value needs further evaluation, with particular consideration of the cost-effectiveness of such a strategy,&quot; they added.&lt;/p&gt;

                     score="0.005"
                     href="http://www.medpagetoday.com/Geriatrics/GeneralGeriatrics/tb/18183?impressionId=1265787846064"
                     
      &lt;p&gt;A little excess weight after age 70 could do the body some good, according to results of a study involving 9,000 older patients.&lt;/p&gt;
&lt;p&gt;Overweight participants in the cohort study had the lowest 10-year mortality. Normal-weight and obese participants ages 70 to 75 had a similar and slightly higher risk of death, Leon Flicker, PhD, of the Western Australian Center for Health and Aging in Perth, and colleagues found.&lt;/p&gt;
&lt;p&gt;The findings add to evidence suggesting that being overweight in older age is not such a bad thing and might even be beneficial.&lt;/p&gt;
&lt;p&gt;&quot;These results lend further credence to claims that the body mass index [BMI] thresholds for overweight and obese are overly restrictive for older people,&quot; the researchers concluded in an article in the &lt;em&gt;Journal of the American Geriatrics Society&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;The authors also found that a sedentary lifestyle doubled the mortality risk for older women but did not affect survival of older men.&lt;/p&gt;
&lt;p&gt;The World Health Organization has established four BMI thresholds to characterize body weight: &lt;ul&gt; &lt;li&gt;&amp;lt;18.5 kg/m&lt;sup&gt;2&lt;/sup&gt;, underweight&lt;/li&gt; &lt;li&gt;18.5 to 24.9 kg/m&lt;sup&gt;2&lt;/sup&gt;, normal weight&lt;/li&gt; &lt;li&gt;25 to 29.9 kg/m&lt;sup&gt;2&lt;/sup&gt;, overweight&lt;/li&gt; &lt;li&gt;&amp;#8805;30 kg/m&lt;sup&gt;2&lt;/sup&gt;, obese&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;The authors noted that the thresholds were derived primarily from studies of younger and middle-age adults. Whether the cut points for overweight and obese are appropriate for older individuals has remained unclear.&lt;/p&gt;
&lt;p&gt;Two systematic reviews and a meta-analysis showed no increased mortality risk associated with a BMI in the overweight range for older people (&lt;em&gt;Arch Intern Med&lt;/em&gt; 2001; 161: 1194-1203, &lt;em&gt;Obesity Rev&lt;/em&gt; 2007; 8: 41-59). However, methodologic differences complicated the comparison of different studies, Flicker and colleagues wrote.&lt;/p&gt;
&lt;p&gt;So they sought to address some of the uncertainty by analyzing data from two large Australian cohort studies involving more than 9,000 individuals ages 70 to 75 (4,677 men, 4,563 women).&lt;/p&gt;
&lt;p&gt;The principal objectives were to determine the BMI threshold associated with the lowest mortality in older people and to determine whether the relationship between BMI and mortality differed between men and women.&lt;/p&gt;
&lt;p&gt;Data for the analysis came from self-reported measures of height and weight, which the authors used to calculate BMI for the study participants. Participants also provided demographic, lifestyle, and health information.&lt;/p&gt;
&lt;p&gt;Using the WHO criteria for BMI, the authors found that 1.3% of men and 3.1% of women were underweight; 43.5% of men and 50.3% of women were normal weight; 44.3% of men and 33.5% of women were overweight; and 11% of men and 13.1% of women were obese.&lt;/p&gt;
&lt;p&gt;During 10 years of follow-up, overweight study participants had a 13% lower risk of death compared with normal-weight participants (HR 0.87, 95% CI 0.78 to 0.94). Obese participants had a mortality risk similar to that of normal-weight participants (HR 0.98, 95% CI 0.85 to 1.11).&lt;/p&gt;
&lt;p&gt;Self-reported sedentary lifestyle doubled the mortality risk for women across all BMI categories (HR 2.08, 95% CI 1.79 to 2.41). In contrast, sedentary lifestyle increased the mortality risk for men by 28% (HR 1.28, 95% CI 1.14 to 1.44).&lt;/p&gt;
&lt;p&gt;Separate analyses involving common causes of death, such as cardiovascular disease and cancer, showed similar relationships between BMI and mortality risk.&lt;/p&gt;
&lt;p&gt;&quot;Even after removing the effects of early mortality, those who were overweight were still at lowest risk, a finding consistent with the observation that weight loss in older age groups is associated with greater mortality,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;&quot;Overweight older people are not at greater mortality risk, and there is little evidence that dieting in this age group confers any benefit,&quot; they added.&lt;/p&gt;

                     score="0.004"
                     href="http://www.medpagetoday.com/Geriatrics/GeneralGeriatrics/tb/18173?impressionId=1265787846064"
                     
      &lt;p&gt;Raising seniors&apos; copayments for ambulatory care to offset increasing healthcare costs may backfire on insurers, researchers asserted.&lt;/p&gt;
&lt;p&gt;Seniors enrolled in Medicare plans that increased copayments had significantly fewer outpatient visits but spent more time in the hospital than patients in plans that left copayments untouched, according to Amal Trivedi, MD, MPH, of Brown University in Providence, R.I., and colleagues.&lt;/p&gt;
&lt;p&gt;Assuming an average reimbursement of $60 for an outpatient visit, seven annual visits per enrollee, and an average copay increase of $8.50 per visit, a plan should save $7,150 for every 100 enrollees, they noted in the Jan. 28 &lt;em&gt;New England Journal of Medicine&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;But, assuming an average cost of $11,065 per hospitalization of a person 65 to 84, the researchers estimated that the costs for inpatient care would actually increase by $24,000 for every 100 enrollees in the year after copays are increased.&lt;/p&gt;
&lt;p&gt;Even using more conservative criteria, the increased costs for inpatient care would nearly double any savings from increasing copays, they argued.&lt;/p&gt;
&lt;p&gt;&quot;Cost-sharing has generally been thought to reduce total healthcare spending without harming health for the average person,&quot; the researchers wrote, but these results suggest increasing copays in Medicare beneficiaries &quot;may be a particularly ill-advised cost-containment strategy.&quot;&lt;/p&gt;
&lt;p&gt;Increasing copayments may be particularly harmful to older patients, they said, because they have lower incomes and are more likely to have poor health and greater out-of-pocket healthcare expenses than younger patients.&lt;/p&gt;
&lt;p&gt;To explore the issue in a Medicare population, Trivedi and colleagues compared the use of outpatient and inpatient care between enrollees in 18 plans that increased copays for ambulatory care and 18 that did not. The study included 899,060 patients.&lt;/p&gt;
&lt;p&gt;According to data from the Medicare Healthcare Effectiveness Data and Information Set from the Centers for Medicare and Medicaid Services, mean copays increased during the study period for both primary care ($7.38 to $14.38) and specialty care ($12.66 to $22.05) in the case plans.&lt;/p&gt;
&lt;p&gt;Mean copays remained stable at $8.33 and $11.38 for primary and specialty care, respectively, in the control plans.&lt;/p&gt;
&lt;p&gt;In both groups, there were increases in the number of ambulatory visits over time, but the increase was smaller in the plans that raised copays.&lt;/p&gt;
&lt;p&gt;There was also a rise in the number of hospitalizations, the proportion of patients who were hospitalized, and the length of time spent in the hospital in both groups, but there were larger increases in the plans that increased copays.&lt;/p&gt;
&lt;p&gt;Compared with the control plans, in the year after the increase in copays, case plans had: &lt;ul&gt; &lt;li&gt;19.8 fewer annual outpatient visits per 100 enrollees (95% CI 16.6 to 23.1)&lt;/li&gt; &lt;li&gt;2.2 additional annual hospital admissions per 100 enrollees (95% CI 1.8 to 2.6)&lt;/li&gt; &lt;li&gt;13.4 more annual inpatient days per 100 enrollees (95% CI 10.2 to 16.6)&lt;/li&gt; &lt;li&gt;A 0.7% increase in the proportion of enrollees who were hospitalized (95% CI 0.51% to 0.95%)&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;The findings were amplified among enrollees living in areas of lower income and education, black patients, and those who had hypertension, diabetes, or a history of myocardial infarction.&lt;/p&gt;
&lt;p&gt;Trivedi and colleagues noted some limitations of the analysis: it was not randomized, and unmeasured differences could have influenced the results.&lt;/p&gt;
&lt;p&gt;Also, the case and control plans could not be matched in a geographic area smaller than census region because of the small number of Medicare plans, and data were lacking on diagnoses, procedures, and costs associated with hospital admissions and outpatient visits.&lt;/p&gt;

                     score="0.004"
                     href="http://www.medpagetoday.com/HematologyOncology/ColonCancer/tb/18164?impressionId=1265787846064"
                     
      Patients 65 and older are as suitable as younger individuals for CT colonography, said researchers conducting a large retrospective study.&lt;br&gt;
&lt;br&gt;Advanced neoplasias were detected with CT colonography  --  often called &quot;virtual colonoscopy&quot;  --  in older patients at more than double the rate in the general screening population, reported David H. Kim, MD, of the University of Wisconsin in Madison, Wis., and colleagues in the February issue of &lt;em&gt;Radiology&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;They found that 7.6% of older patients had advanced neoplasias, compared with 3.2% of all patients screened in the university&apos;s clinic (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;On the basis of this and other findings in 577 individuals 65 and older versus the entire group of 3,120 patients undergoing the procedure, Kim and colleagues concluded that &quot;CT colonography performance is maintained in an older cohort.&quot;&lt;/p&gt;
&lt;p&gt;&quot;Overall, the observations from this clinical experience confirm that CT colonography may be a valuable screening modality in the older population,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;On the other hand, the study did not address several objections raised by the Centers for Medicare and Medicaid Services (CMS) in its decision last year to deny Medicare coverage for the procedure. (See &lt;a href=&quot;http://www.medpagetoday.com/PublicHealthPolicy/Medicare/14186&quot; mce_href=&quot;http://www.medpagetoday.com/PublicHealthPolicy/Medicare/14186&quot; target=&quot;_blank&quot;&gt;Medicare Finalizes Denial of Virtual Colonoscopy Coverage&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;CMS had pointed to relatively low sensitivity of CT colonography compared with optical colonoscopy in prospective trials, especially for small lesions.&lt;/p&gt;
&lt;p&gt;The agency also determined that CT colonography increased the costs of positive findings, since abnormalities in the CT scans must be confirmed with optical colonoscopy. In addition, CMS said there was no evidence to support claims that the less invasive imaging procedure would be more acceptable to patients and therefore would raise screening rates.&lt;/p&gt;
&lt;p&gt;The data analyzed by Kim and colleagues did not allow for calculations of false-negative rates or predictive values of positive or negative findings. Nor did the researchers report cost information.&lt;/p&gt;
&lt;p&gt;Mean age of their older cohort was 69.2 (SD 3.8). The oldest was 79.&lt;/p&gt;
&lt;p&gt;The researchers reported that 15.3% of the older patients were referred for optical colonoscopy on the basis of the CT results, compared with 7.9% of the overall screening group.&lt;/p&gt;
&lt;p&gt;Less than 4% of positive findings were determined to be false with the optical procedure (3.6% for polyps 6 to 10 mm in diameter, 2.1% for larger lesions).&lt;/p&gt;
&lt;p&gt;Of the 59 advanced neoplasias identified in the older patients, all but three were at least 10 mm in size.&lt;/p&gt;
&lt;p&gt;The scans also suggested abnormalities outside the colon in 89 (15.4%) patients. Of these, 45 received a full workup, which revealed substantial and previously unsuspected diagnoses in 21 cases  -- 18 were vascular aneurysms. The other three included one lung tumor, a femoral hernia, and a malrotation.&lt;/p&gt;
&lt;p&gt;Kim and colleagues reported that no &quot;substantial complications&quot; such as perforations or major hemorrhage occurred in the older patients, either with the CT scan or follow-up colonoscopy.&lt;/p&gt;
&lt;p&gt;They also indicated that the ratio of large to small neoplasias was similar in the older patients compared with their CT screening group as a whole. Histologic and morphologic findings were similar as well.&lt;/p&gt;
&lt;p&gt;The researchers cited the observational nature of the study, in which negative findings were not corroborated with optical colonoscopy, and its restriction to a single center as its main limitations.&lt;/p&gt;
