Venous thromboembolism (VTE) is a major US health problem. However, the total number of US inpatients who are at risk for VTE is unknown. Our objective was to estimate the number of US acute-care hospital inpatients who were at risk for VTE according to criteria established by the Seventh American College of Chest Physicians (ACCP) Consensus Conference on Antithrombotic and Thrombolytic Therapy guidelines for VTE prevention. Using the 2003 Nationwide Inpatient Sample from the Healthcare Cost and Utilization Project (HCUP), patient diagnoses and procedures were examined to identify major surgery patients (age 18 years, length of hospital stay 2 days) and medical patients (age 40 years, length of hospital stay 2 days). ACCP guidelines were used to estimate the number of surgical and medical patients at risk of developing VTE. Of an estimated 38,220,659 discharges in 2003, 7,786,390 (20%) were surgical inpatients; 44% of which were at low risk for VTE, while 15%, 24%, and 17% were at moderate, high, and very high risk for VTE, respectively. Of the remaining 15,161,586 medical patients, 7,742,419 (51%) met ACCP VTE risk criteria. Over 12 million patients, comprising 31% of US hospital discharges in 2003, were at risk of VTE. Given the existence of internationally-accepted evidence-based guidelines for prevention of VTE, research is required to establish if this patient population is receiving recommended VTE prophylaxis.

The cost-effectiveness ratios for standard CHD treatments varied by over 100-fold. Large amounts of NHS funding are being spent on relatively less cost-effective interventions, such as statins for primary prevention, angioplasty and CABG surgery. This merits debate.
Objective To assess the association between different types of organisation and the results from economic evaluations. Design Retrospective pairwise comparison of evidence submitted to the technology appraisal programme of the National Institute for Clinical Excellence (NICE) by manufacturers of the relevant healthcare technologies and by contracted university based assessment groups. Data sources Data from the first 62 appraisals. Main outcome measure Incremental cost effectiveness ratios. Results Data from 27 of the 62 appraisals could be compared. The analysis of 54 pairwise comparisons showed that manufacturers' estimates of incremental cost effectiveness ratios were lower (suggesting a more cost effective use of resources) than those produced by the assessment groups (25 were lower, 29 were the same, none were higher, P < 0.01). Restriction of this dataset to include only one pairwise comparison per appraisal (27 pairs) produced a similar result (21 were lower, two were the same, four were higher, P < 0.001). Conclusions The estimated incremental cost effectiveness ratios submitted by manufacturers were on average significantly lower than those submitted by the assessment groups. These results show that an important role of NICE's appraisal committee, and of decision makers in general, is to determine which economic evaluations, or parts of evaluations, should be given more credence.
Objectives. We estimated life-years gained from cardiological treatments and cardiovascular risk factor changes in England and Wales between 1981 and 2000.Methods. We used the IMPACT model to integrate data on the number of coronary heart disease patients, treatment uptake and effectiveness, risk factor trends, and median survival in coronary heart disease patients.Results. Compared with 1981, there were 68 230 fewer coronary deaths in 2000. Approximately 925 415 life-years were gained among people aged 25-84 years (range: 745 195-1 138 655). Cardiological treatments for patients accounted for approximately 194 145 life-years gained (range: 142 505-259 225), and population risk factor changes accounted for approximately 731 270 life-years gained (range; 602 695-879 430).Conclusions. Modest reductions in major risk factors led to gains in life-years 4 times higher than did cardiological treatments. Effective policies to promote healthy diets and physical activity might achieve even greater gains.

In patients with RA, rofecoxib demonstrates a greater degree of efficacy than placebo, while having a comparable safety profile. Rofecoxib demonstrates a similar degree of efficacy as naproxen, but with a significantly lower rate of ulceration and gastrointestinal bleeding. Rofecoxib was associated with a greater risk for MI, but the exact significance and pathophysiology of this possible relationship is unclear. Rofecoxib was voluntarily withdrawn from global markets in October 2004. It cannot therefore be prescribed and therefore there are no implications for practice concerning its use. None the less when considering which NSAID to use, it must be borne in mind that the toxicity of NSAIDs is variable amongst patients and drugs and it tends to be dose related and associated with variation in the mode of action, absorption, distribution and metabolism. There remains a number of questions over both the benefits and risks associated with Cox II selective agents and further work is ongoing. It is likely that this issue will not be resolved until research has enabled a fuller understanding of the complex mechanism by which the Cox system operates.
For an individual with RA the potential benefits of celecoxib need to be balanced against the uncertainty that the short-term reduced incidence of upper GI complications are maintained in the long-term and its increased cost in comparison to traditional NSAIDs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
