      &lt;p&gt;Patients with active inflammatory bowel disease (IBD) could be at far greater risk for potentially deadly blood clots than doctors previously thought, a new British study found.&lt;/p&gt;
&lt;p&gt;Nonhospitalized patients with active IBD are 16 times more likely to suffer venous thromboembolism than the general population, with an occurrence rate of 6.4 per 1,000 person-years (HR 15.8, 95% CI 9.8 to 25.5, &lt;em&gt;P&lt;/em&gt;&amp;lt;0.0001), according to an online report in the Feb. 9 issue of &lt;em&gt;The Lancet&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;The authors concluded that such patients could benefit from preventative treatment to prevent blood clotting.&lt;/p&gt;
&lt;p&gt;&quot;Despite the low absolute risks during nonhospitalised periods, these results suggest that active inflammatory bowel disease in ambulatory patients might be a far greater risk factor for venous thromboembolism than previously recognised,&quot; Matthew J. Grainge, MD, of the University of Nottingham, and colleagues wrote.&lt;/p&gt;
&lt;p&gt;Patients with venous thromboembolism in the leg have a short term-mortality rate of about 6%, increasing as high as 20% when the clot has circulated to the lung.&lt;/p&gt;
&lt;p&gt;Researchers believe that infection and inflammation, such as occur in IBD, predispose patients to this life-threatening condition, and those with inflammatory bowel disease seem to be at particular risk.&lt;/p&gt;
&lt;p&gt;Grainge and colleagues used records from the U.K. General Practice Research Database from November 1987 through July 2001, to match 13,756 patients with IBD against 71,672 controls without the disease.&lt;/p&gt;
&lt;p&gt;Of the subjects, 139 patients and 165 controls developed a blood clot during the study period.&lt;/p&gt;
&lt;p&gt;Their results agreed with previous studies indicating that patients hospitalized for IBD are at high risk for venous thromboembolism. However, the new study also found the danger extends to nonhospitalized IBD patients, particularly during a flare-up.&lt;/p&gt;
&lt;p&gt;Overall, the researchers reported, patients with IBD had three times as much risk of an embolism as controls (HR 3.4, 95% CI 2.7 to 4.3; &lt;em&gt;P&lt;/em&gt;&amp;lt;0.0001) with an occurrence rate of 2.6 per 1,000 per person-years.&lt;/p&gt;
&lt;p&gt;During a flare-up, IBD patients were at dramatically greater risk.&lt;/p&gt;
&lt;p&gt;The researchers cautioned that the study excluded patients likely to have received corticosteroids for chronic respiratory disease and rheumatoid arthritis, so the results may not reflect blood clotting rates in these populations.&lt;/p&gt;
&lt;p&gt;They also noted that they relied on anonymous patient records and were dependent on family doctors&apos; diagnoses of inflammatory bowel disease, flare-ups and venous thromboembolism.&lt;/p&gt;
&lt;p&gt;Despite the limitations of the study, they argued that research into ways to prevent embolism in IBD outpatients is warranted.&lt;/p&gt;
&lt;p&gt;&quot;We believe that the medical profession needs to recognise the increased risk in people with inflammatory bowel disease when assessing the likelihood of venous thromboembolism and to address the difficulty of reducing this risk in patients with a flare who are not admitted to hospital,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;They suggested that strategies used to prevent blood clots in hospitalized patients  --  courses of low molecular weight heparin or other newly available anticoagulants  --  might be also be used to prevent clots in nonhospitalized IBD patients experiencing a flare-up.&lt;/p&gt;
&lt;p&gt;In an accompanying editorial, Geoffrey C. Nguyen, MD, and Erik L. Yeo, MD, of the University of Toronto, noted that &quot;the use of steroid prescriptions as a surrogate indicator of acute disease flare restricts the applicability of Grainge and colleagues&apos; findings to flares that are moderate to severe. Whether patients with mild flares are also at increased risk is not clear.&quot;&lt;/p&gt;
&lt;p&gt;&quot;Recognition of venous thromboembolism might be increased during periods of frequent contact with doctors, such as during flares compared with during remission of inflammatory bowel disease, thus potentially introducing a bias in ascertainment of venous thromboembolism,&quot; they added.&lt;/p&gt;
&lt;p&gt;Nguyen and Yeo also argued that the clinical efficacy and cost-effectiveness of pharmacological prevention in patients with inflammatory bowel disease should be proven before it is routinely recommended during acute flares.&lt;/p&gt;
&lt;p&gt;However, they acknowledged that such evidence could be difficult to acquire, given the low numbers of nonhospitalized IBD patients who suffer venous thromboembolism.&lt;/p&gt;
&lt;p&gt;&quot;A pragmatic initial approach to reduction of the rates of morbidity and mortality resulting from venous thromboembolism in ambulatory patients with inflammatory bowel disease would be nonpharmacological thromboprophylaxis, including patients&apos; education and awareness of risk and signs and symptoms of venous thromboembolism, and use of support stockings,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;&quot;Physicians should clinically assess for signs and symptoms of this embolism during visits for acute flare of inflammatory bowel disease.&quot;&lt;/p&gt;

                     score="0.01"
                     href="http://www.medpagetoday.com/Cardiology/VenousThrombosis/tb/18257?impressionId=1265797265422"
                     
      &lt;p&gt;For patients with suspected deep vein thrombosis, the risk of symptomatic venous thromboembolism after a single, negative whole-leg compression ultrasound examination is low, a meta-analysis showed.&lt;/p&gt;
&lt;p&gt;Pooled results from seven studies showed the risk to be just 0.57% (95% CI 0.25% to 0.89%) through three months of follow-up in patients who were not given anticoagulants, Scott Stevens, MD, of Intermountain Medical Center in Murray, Utah, and colleagues reported in the Feb. 3 issue of the &lt;em&gt;Journal of the American Medical Association&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;The researchers suggested that a repeated compression ultrasound evaluation to detect distal thrombi moving upward  --  recommended in clinical practice guidelines five to seven days after a negative finding  --  may not be necessary.&lt;/p&gt;
&lt;p&gt;&quot;The efficiency and convenience of whole-leg compression ultrasound as a single study is superior to that of repeated ... evaluations,&quot; the researchers concluded.&lt;/p&gt;
&lt;p&gt;However, an accompanying editorial by Robert McNutt, MD, PhD, of Rush University Medical Center in Chicago, and Edward Livingston, MD, of the University of Texas Southwestern Medical Center in Dallas, cautioned against basing clinical decisions on a meta-analysis.&lt;/p&gt;
&lt;p&gt;They pointed to the variation in event rates among the seven included studies, ranging from 0.24% to 1.95%. The highest rate was found in hospitalized patients, although most of the studies included ambulatory patients.&lt;/p&gt;
&lt;p&gt;&quot;So using this average probability [0.57%] for clinical decision making in some clinical contexts may do more harm than good,&quot; they wrote. &quot;Greater detail about individual patient scenarios is necessary to facilitate better application of the study results to individual patients.&quot;&lt;/p&gt;
&lt;p&gt;Although whole-leg compression ultrasound reliably identifies the presence or absence of deep vein thrombosis above the knee, its accuracy for thrombi below the knee is less certain, according to Stevens and colleagues.&lt;/p&gt;
&lt;p&gt;So guidelines have recommended repeating the examination after a negative finding to rule out the upward propagation of a distal thrombus.&lt;/p&gt;
&lt;p&gt;But only 1% to 2% of those repeat exams actually detect thrombus propagation.&lt;/p&gt;
&lt;p&gt;Thus, a single whole-leg compression ultrasound may reliably exclude both proximal and distal deep vein thrombosis, the authors said.&lt;/p&gt;
&lt;p&gt;They reviewed the literature to assess the risk of venous thromboembolism in patients with suspected lower extremity deep vein thrombosis who had a single, negative whole-leg compression ultrasound and who had not received anticoagulation treatments for 90 days.&lt;/p&gt;
&lt;p&gt;Seven studies were included  --  one randomized controlled trial and six prospective cohort studies  --  comprising 4,731 patients, mostly from the ambulatory setting.&lt;/p&gt;
&lt;p&gt;Through three months of follow-up, 0.7% of patients had either confirmed venous thromboembolism or suspected venous thromboembolism-related death. All nine who died were either acutely ill, hospitalized patients, or patients with advanced cancer.&lt;/p&gt;
&lt;p&gt;The risk of having an event during follow-up increased with greater pretest probability of having deep vein thrombosis  --  0.29% for low risk, 0.82% for moderate risk, and 2.49% for high risk.&lt;/p&gt;
&lt;p&gt;However, because of low patient numbers, the researchers wrote, &quot;using a single negative whole-leg compression ultrasound result as the sole diagnostic modality in patients with high pretest probability of deep vein thrombosis requires further study.&quot;&lt;/p&gt;
&lt;p&gt;The authors listed several limitations of the analysis: &lt;ul&gt; &lt;li&gt;The variability in ultrasound techniques between the included studies may limit the validity and generalizability of the findings.&lt;/li&gt; &lt;li&gt;The pretest probability of deep vein thrombosis was not assessed using a standardized clinical prediction rule by most studies.&lt;/li&gt; &lt;li&gt;The findings might have limited generalizability to pregnant women, patients with cancer, and inpatients, who were underrepresented in the studies.&lt;/li&gt; &lt;li&gt;Longer-term outcomes were not assessed.&lt;/li&gt; &lt;li&gt;The findings might have been affected by verification bias, because only patients with symptoms were evaluated for venous thromboembolism during follow-up.&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;

                     score="0.009"

      Herbal medicines are not always the harmless nostrums that many patients and even some physicians think, but may actually contribute to cardiovascular morbidity and mortality, researchers warned in a review covering 44 years of research into the subject.&lt;br&gt;
&lt;br&gt;Many such products, including aloe vera, ginkgo biloba, ginseng, and green tea, can interact with conventional cardiovascular drugs and lead to serious adverse reactions, according to Arshad Jahangir, MD, of the Mayo Clinic in Scottsdale, Ariz., and two other Mayo physicians.&lt;br&gt;
&lt;br&gt;&quot;There is a clear need for better public and physician understanding of herbal products through health education, early detection and management of herbal toxicities, scientific scrutiny of their use, and research on their safety and effectiveness,&quot; they wrote in the Feb. 9 &lt;em&gt;Journal of the American College of Cardiology&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Jahangir and colleagues also called for increased regulation of such products, at least requiring manufacturers of herbal medicines to register with the FDA and provide evidence of good manufacturing practices.&lt;/p&gt;
&lt;p&gt;&quot;Some of these adverse drug reactions are preventable,&quot; Jahangir told &lt;em&gt;MedPage Today&lt;/em&gt; in a telephone interview. &quot;Simple things like taking a good history or giving that history and discussing these issues, probably we can avoid [such reactions].&quot;&lt;/p&gt;
&lt;p&gt;Other physicians contacted by &lt;em&gt;MedPage Today&lt;/em&gt; and ABC News agreed that the growth in popularity of herbal medicines poses problems for physicians and patients.&lt;/p&gt;
&lt;p&gt;&quot;Because these remedies are &apos;natural,&apos; their potential dangers are not considered the same way they would be if they were medication,&quot; commented Suzanne Steinbaum, MD, a cardiologist at Lenox Hill Hospital in New York City, in an e-mail.&lt;/p&gt;
&lt;p&gt;&quot;For many reasons, patients tend not to disclose to their doctors if they are taking herbal remedies, including fear that their doctors won&apos;t approve or they will be told to stop them,&quot; Steinbaum added. &quot;This lack of knowledge and full-disclosure, for some, might be a fatal omission.&quot;&lt;/p&gt;
&lt;p&gt;Jahangir and colleagues reviewed nearly 90 publications that have addressed herbal or complementary therapies and cardiovascular effects since 1966.&lt;/p&gt;
&lt;p&gt;Their &lt;em&gt;JACC&lt;/em&gt; article listed 15 common herbal medicines known to interact adversely with conventional cardiovascular drugs.&lt;/p&gt;
&lt;p&gt;In many cases, the herbal products compete with the regular medicines for the same drug-metabolizing cytochrome P450 enzymes, potentiating the latter&apos;s effects. In other cases, the herbal products have their own cardiovascular effects.&lt;/p&gt;
&lt;p&gt;Many physicians already know that grapefruit juice occupies the CYP3A4 enzyme, leading to slower-than-expected metabolism and, therefore, higher blood levels of a host of pharmaceuticals.&lt;/p&gt;
&lt;p&gt;These include the statins, calcium channel antagonists, several common anti-arrhythmic drugs, and the angiotensin receptor blocker irbesartan (Avapro), Jahangir and colleagues noted.&lt;/p&gt;
&lt;p&gt;Garlic is one of several common herbal remedies with specific cardiovascular effects in its own right (others include ginkgo biloba, ginseng, and saw palmetto). Garlic inhibits platelet aggregation and thus can lead to increased bleeding risks when combined with aspirin, clopidogrel (Plavix), or warfarin (Coumadin), the researchers noted.&lt;/p&gt;
&lt;p&gt;The Mayo group identified 10 herbal products that increase bleeding risks with anticoagulant and antiplatelet drugs, as well as 14 that can induce arrhythmias.&lt;/p&gt;
&lt;p&gt;In all, Jahangir and colleagues listed 27 herbal products that patients with cardiovascular diseases would do well to avoid. These include such common and harmless-seeming products as green tea, capsicum pepper, licorice, and kelp, as well as grapefruit juice and garlic.&lt;/p&gt;
&lt;p&gt;&quot;We need to check with our patients what type of products they are using, to identify these potential interactions,&quot; Jahangir told &lt;em&gt;MedPage Today&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;He cited the previously reported figure of 100,000 deaths annually from drug interactions, adding, &quot;We don&apos;t even know how many of these are due to use of compounds that we are not aware that our patients are taking.&quot;&lt;/p&gt;
&lt;p&gt;Jahangir said he was surprised, in preparing the review, at the scale of hebal medicine use in the U.S.&lt;/p&gt;
&lt;p&gt;He and his colleagues found data from the 1990s suggesting that more patients consult complementary and alternative medicine providers than regular physicians.&lt;/p&gt;
&lt;p&gt;The total annual out-of-pocket expenditure on complementary and alternative medicine services and products also was greater than for conventional physician services.&lt;/p&gt;
&lt;p&gt;&quot;The surprise for me was . . . how much people are willing to spend on a type of therapy which has not shown, in any scientific way, to be effective or safe,&quot; Jahangir said.&lt;/p&gt;
&lt;p&gt;He added that the trend may reflect shortcomings of the conventional medical system.&lt;/p&gt;
&lt;p&gt;&quot;What is the reason people are going there? Is it because there is some unmet type of need that we are not recognizing as practitioners of conventional medicine?&quot;&lt;/p&gt;
&lt;p&gt;Jahangir said it may be that physicians aren&apos;t spending enough time with patients to understand their true needs. He said it appears that, &quot;despite the advancement in our technology and new medicines, there is a demand for alternative therapies that is increasing.&quot;&lt;/p&gt;
&lt;p&gt;He recommended that, in addition to asking patients in detail about herbal and other alternative therapies they may be using, physicians should educate themselves on what these therapies purport to do and what is known about their real biological effects.&lt;/p&gt;
&lt;p&gt;The &lt;a href=&quot;http://nccam.nih.gov&quot; mce_href=&quot;http://nccam.nih.gov&quot; target=&quot;_blank&quot;&gt;National Center for Complementary and Alternative Medicine&lt;/a&gt; at the National Institutes of Health is a good starting point for such information, both for physicians and for patients, Jahangir said.&lt;/p&gt;
&lt;p&gt;Lenox Hill&apos;s Steinbaum said it was important that conventional physicians &quot;become more open-minded and accepting&quot; of alternative medicine, if only because so many of their patients are already practicing it.&lt;/p&gt;
&lt;p&gt;David Meyerson, MD, JD, a Johns Hopkins University cardiologist, told &lt;em&gt;MedPage Today&lt;/em&gt; and ABC News in an e-mail that he advises patients to limit their use of &quot;unstudied and unproven and FDA-unregulated herbal medications.&quot;&lt;/p&gt;
&lt;p&gt;&quot;It&apos;s unfortunately very big business, and potential drug interactions and potential harmful effects abound,&quot; he wrote.&lt;/p&gt;
&lt;p&gt;But another physician criticized the Mayo physicians&apos; emphasis on adverse effects in their review.&lt;/p&gt;
&lt;p&gt;&quot;For many of products listed, evidence for side effects seems to be minimal,&quot; Scott Grundy, MD, of the University of Texas Southwestern Medical Center in Dallas, argued in an e-mail.&lt;/p&gt;
&lt;p&gt;He agreed that the efficacy and safety of such drugs remains largely unproven, but added, &quot;It is mainly for these reasons that they cannot be recommended for use.&quot;&lt;/p&gt;
&lt;p&gt;Creating alarm about side effects &quot;may not be the appropriate way to discourage their use,&quot; Grundy said.&lt;/p&gt;

                     score="0.008"

      &lt;p&gt;No evidence of a platelet aggregation rebound occurs with abrupt discontinuation of clopidogrel (Plavix) in patients undergoing percutaneous coronary intervention (PCI), investigators in a randomized clinical trial concluded.&lt;/p&gt;
&lt;p&gt;Values for adenosine diphosphate (ADP)-induced platelet aggregation did not differ significantly between patients whose clopidogrel therapy was withdrawn abruptly and those in whom clopidogrel was tapered before discontinuation, they wrote in an article in the Feb. 9 issue of the &lt;em&gt;Journal of the American College of Cardiology&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;The findings also showed that tapering of clopidogrel does not lead to lower platelet aggregation values after clopidogrel withdrawal, according to Dirk Sibbing, MD, of Technical University Munich in Germany, and colleagues&lt;em&gt;&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;&quot;The time course of platelet aggregation values  --  regardless of the device, the agonist, or the agonist concentration used  --  after clopidogrel cessation provides no evidence for the existence of a rebound phenomenon of platelets after discontinuing clopidogrel,&quot; they wrote in conclusion.&lt;/p&gt;
&lt;p&gt;For patients undergoing PCI, dual antiplatelet therapy with aspirin and clopidogrel has become the mainstay for prevention of thrombotic events. Lifelong aspirin therapy is recommended for patients after PCI, but clinical guidelines recommend discontinuation of clopidogrel after six or 12 months. The standard practice is to withdraw clopidogrel abruptly, the authors noted.&lt;/p&gt;
&lt;p&gt;Recent studies have shown a clustering of thrombotic events in the first few weeks after discontinuation of long-term clopidogrel therapy. The observations have led to the hypothesis of a rebound phenomenon of platelet aggregation. However, the hypothesis had not been examined specifically within the context of clopidogrel withdrawal.&lt;/p&gt;
&lt;p&gt;&quot;Because different studies have demonstrated that insufficient suppression of platelet reactivity to ADP is associated with an increased risk of thrombotic events after coronary stent placement, the observed clustering of adverse events reported in clinical studies might be related to an intermittent status of platelet hyperreactivity or so-called platelet rebound with very high ADP-induced platelet aggregation levels,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;&quot;A tapering of clopidogrel treatment over a certain period of time before stopping the intake of the drug completely might provide a beneficial treatment strategy to attenuate this supposed rebound phenomenon of platelets.&quot;&lt;/p&gt;
&lt;p&gt;Sibbing and colleagues designed a randomized clinical trial to determine whether a rebound phenomenon exists after discontinuation of clopidogrel and whether the rebound can be attenuated by a clopidogrel-tapering regimen.&lt;/p&gt;
&lt;p&gt;The investigators enrolled 69 patients receiving clopidogrel in association with PCI procedures. In all cases, discontinuation of clopidogrel was planned.&lt;/p&gt;
&lt;p&gt;The patients were randomized to two strategies of discontinuation: tapering of the clopidogrel dose over four weeks, followed by discontinuation; or treatment for four weeks, as planned, followed by abrupt discontinuation.&lt;/p&gt;
&lt;p&gt;Investigators assessed platelet aggregation at enrollment and during weeks two through eight after randomization. Aggregation was assessed simultaneously by light transmission aggregometry (LTA) and multiple electrode aggregometry (MEA).&lt;/p&gt;
&lt;p&gt;The primary endpoint was the highest rate of ADP-induced platelet aggregation by LTA in weeks five through eight after clopidogrel withdrawal.&lt;/p&gt;
&lt;p&gt;Platelet aggregation by LTA peaked at 73% in the group that had clopidogrel abruptly withdrawn and at 69.3% in the tapering group, resulting in a nonsignificant difference (&lt;em&gt;P&lt;/em&gt;=0.21). The between-group values did not differ across the range of ADP concentrations used (1.25 to 20 &amp;#181;mol/L).&lt;/p&gt;
&lt;p&gt;Results by MEA were similar: The peak aggregation value associated with abrupt withdrawal was 925 AU x min compared with 890 AU x min with clopidogrel tapering (&lt;em&gt;P&lt;/em&gt;=0.55).&lt;/p&gt;
&lt;p&gt;Studies with different agonists of platelet aggregation also yielded similar results in the two patient groups.&lt;/p&gt;
&lt;p&gt;Despite finding no difference between the two strategies for clopidogrel withdrawal, the authors did not rule out the possibility of a beneficial effect of tapering clopidogrel.&lt;/p&gt;
&lt;p&gt;&quot;It could be hypothesized that, apart from the maximal values of platelet aggregation observed, a more gradual increase of platelet aggregation values achieved by a clopidogrel-tapering regimen is beneficial for the reduction of thrombotic events,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;&quot;In fact, we observed a relatively rapid increase of platelet aggregation values in the [abrupt withdrawal] group of patients in our study. Whether this rapid increase might be disadvantageous in case of stopping clopidogrel treatment remains uncertain.&quot;&lt;/p&gt;

                     score="-0.006"
                     href="http://www.medpagetoday.com/CriticalCare/CHF/tb/16412?impressionId=1265797265422"
                     
      When comparing hospitals&apos; quality of care for heart failure, it&apos;s important to include data on all patients, not just those who died, researchers have concluded.&lt;br&gt;
&lt;br&gt;Previous studies have found wide variation in the resources expended at hospitals for the treatment of chronic diseases, including heart failure.&lt;br&gt;
&lt;br&gt;These findings have led some to conclude that lower-spending hospitals should be seen as benchmarks for care, according to an article in the November issue of &lt;em&gt;Circulation: Cardiovascular Quality and Outcomes&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;But, authors Michael Ong, MD, PhD, of UCLA, and colleagues argued that previous studies included analyses of resources used for deceased patients only, the so-called &quot;Looking Back&quot; method, which precluded comparisons of health outcomes such as survival.&lt;br&gt;
&lt;br&gt;In an analysis of all patients with heart failure treated at six California centers  --  including those who survived (the so-called &quot;Looking Forward&quot; method)  --  Ong&apos;s group found that centers that used the most resources had the lowest mortality rates, suggesting that the high spenders were not necessarily less efficient than the low spenders.&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&quot;Focusing only on expired individuals may overlook mortality variation as well as associations between greater resource use and lower mortality,&quot; the researchers said.&lt;/p&gt;
&lt;p&gt;&quot;We believe that future studies should use the &apos;Looking Forward&apos; approach to ensure that important outcomes are not missed.&quot;&lt;/p&gt;
&lt;p&gt;Clyde Yancy, MD, medical director of the Baylor Heart and Vascular Institute in Dallas and president of the American Heart Association, said the findings could help inform the current debate on healthcare reform.&lt;/p&gt;
&lt;p&gt;&quot;Before we accept a system that says the only thing that matters is being the low-cost provider, we need to be somewhat circumspect about that approach and recognize that quality absolutely must factor into the equation,&quot; he said.&lt;/p&gt;
&lt;p&gt;&quot;Outcomes must be considered. Quality of life must be considered,&quot; he said.&lt;/p&gt;
&lt;p&gt;In certain cases, he said, centers that use more resources can achieve better health outcomes than those that use fewer.&lt;/p&gt;
&lt;p&gt;&quot;I think the important message here is that we do derive a premium when we invest in those centers that are focused on quality and are able to generate better metrics of care, like survival,&quot; he said.&lt;/p&gt;
&lt;p&gt;&quot;That comes at a cost, and sometimes when we look at the cost equation we must acknowledge that we are getting return on that investment. Not to say that it happens consistently, but it does happen.&quot;&lt;/p&gt;
&lt;p&gt;Ong and colleagues collected data on 3,999 Medicare beneficiaries (mean age 80) hospitalized for heart failure at six California teaching hospitals: University of California medical centers in Davis, Irvine, Los Angeles, San Diego, and San Francisco, as well as Cedars-Sinai Medical Center in Los Angeles.&lt;/p&gt;
&lt;p&gt;They assessed total days spent in the hospital, total hospital direct costs, and death within 180 days after initial admission. This was the &quot;Looking Forward&quot; method.&lt;/p&gt;
&lt;p&gt;This analysis identified a wide variation in 180-day mortality rates (from 17% to 26%), in resource use measured by total hospital days (7.8 to 14.9), and in an index for total direct costs (0.66 to 1.30).&lt;/p&gt;
&lt;p&gt;In general, the hospitals that used the most resources had lower mortality rates. The center with the highest resource use on both measures (the centers remained anonymous) had the lowest mortality&lt;strong&gt; &lt;/strong&gt;rate.&lt;/p&gt;
&lt;p&gt;&quot;Although we do not intend to suggest that this correlation implies a causal relationship between more resources and better outcomes,&quot; the researchers said, &quot;it does suggest a need for further work to explore how care processes and resource use during an initial hospitalization and subsequent visits influence health outcomes.&quot;&lt;/p&gt;
&lt;p&gt;Ong and his colleagues also performed a &quot;Looking Back&quot; analysis on the subset of 1,639 patients who died during the study period, assessing total days in the hospital and total hospital direct costs in the 180 days before death.&lt;/p&gt;
&lt;p&gt;The risk-adjusted means ranged from 9.1 to 21.7 days for total time spent in the hospital and 0.91 to 1.79 for total indexed direct costs.&lt;/p&gt;
&lt;p&gt;The values obtained in the &quot;Looking Forward&quot; analysis showed variation in resource use that was 27% less for direct hospital costs and 44% less for total time spent in the hospital compared with the values obtained in the &quot;Looking Back&quot; analysis.&lt;/p&gt;
&lt;p&gt;Yancy said the findings &quot;remind us ... to be careful utilizing low-cost metrics as the preeminent statement of quality because quality has to be more globally considered than just cost.&quot;&lt;/p&gt;
&lt;p&gt;The researchers acknowledged that the study was limited by the exclusion of patients with missing cost data, the inability to identify patients&apos; admissions to other hospitals and to account for outpatient resource use, and the inclusion of resource use for all hospitalizations following the initial admission for heart failure, even those not related to the condition.&lt;/p&gt;
&lt;p&gt;In addition, they said, the findings might not be generalizable to non-teaching hospitals and smaller centers.&lt;/p&gt;

One of Ong&apos;s co-authors received support from the Resource Centers for Minority Aging Research/Center for Health Improvement of Minority Elderly funded by the National Institute on Aging (NIA) and from the UCLA Older Americans Independence Center funded by NIA.&lt;/p&gt;&lt;p&gt;The authors did not report any conflicts of interest.&lt;/p&gt;&lt;/div&gt;&lt;div style=&quot;clear:both;&quot;&gt;&lt;/div&gt;
