Effect of corticosteroids for fetal maturation on perinatal outcomes. NIH Consensus Development Panel on the Effect of Corticosteroids for Fetal Maturation on Perinatal Outcomes.

OBJECTIVE: To develop a consensus on the use of antenatal corticosteroids for fetal maturation in preterm infants. PARTICIPANTS: A nonfederal, nonadvocate, 16-member consensus panel including representatives from neonatology, obstetrics, family medicine, behavioral medicine, psychology, biostatistics, and the public; 19 experts in neonatology, obstetrics, and pharmacology presented data to the consensus panel and a conference audience of approximately 500. EVIDENCE: An extensive bibliography of references was produced for the consensus panel and the conference audience using a variety of on-line databases including MEDLINE. The consensus panel met several times prior to the conference to review the literature. It also commissioned an updated meta-analysis, a neonatal registry review, and an economic analysis that were presented at the conference. The experts prepared abstracts for distribution at the conference, presented data, and answered questions from the panel and audience. The panel evaluated the strength of the scientific evidence using the grading system developed by the Canadian Task Force on the Periodic Health Examination and adapted by the US Preventive Services Task Force. CONSENSUS: The consensus panel, answering predefined consensus questions, developed their conclusions based on the scientific evidence presented in open forum and the scientific literature. CONSENSUS STATEMENT: The consensus panel composed a draft statement that was read in its entirety at the conference for comment. The panel released a revised statement at the end of the conference and finalized the revisions a few weeks after the conference. CONCLUSIONS: Antenatal corticosteroid therapy is indicated for women at risk of premature delivery with few exceptions and will result in a substantial decrease in neonatal morbidity and mortality, as well as substantial savings in health care costs. The use of antenatal corticosteroids for fetal maturation is a rare example of a technology that yields substantial cost savings in addition to improving health.

[Patient-centered evaluation of illness outcome in musculoskeletal diseases: selection and testing of outcome instruments].

Effectiveness research, economic evaluation, epidemiologic studies of disease consequences and clinical quality management all rely on standardized assessment of disease consequences with psychometrically sound questionnaires. For scientific, ethical and economical reasons, careful selection and evaluation of instruments is critical. Selection of instruments includes searches of medical databases (e.g. MEDLINE), testing of face-validity (does the instrument measure what we intend to measure?), and compatibility (is the instrument used internationally?). Evaluation of instruments includes the assessment of reliability, internal consistency and sensitivity. Most important is careful consideration of the practical usefulness (Interpretation of scores and scales, acceptance in the study population). Contact with instrument developers is advisable (Copyright issues, scoring, current version).

The cholesteryl ester transfer protein (CETP) TaqIB polymorphism in the cholesterol and recurrent events study: no interaction with the response to pravastatin therapy and no effects on cardiovascular outcome: a prospective analysis of the CETP TaqIB polymorphism on cardiovascular outcome and interaction with cholesterol-lowering therapy.

OBJECTIVES: On the basis of quantitative coronary angiography data, the cholesteryl ester transfer protein (CETP) TaqIB gene polymorphism has been postulated to predict the progression of coronary atherosclerosis and response to cholesterol-lowering therapy. BACKGROUND: Cholesteryl ester transfer protein mediates the exchange of lipids between anti-atherogenic high-density lipoprotein (HDL) and atherogenic apolipoprotein B containing lipoproteins and therefore plays a key role in human lipid metabolism. Hence, CETP gene polymorphisms may alter susceptibility to atherosclerosis. METHODS: To investigate the significance of the CETP TaqIB gene polymorphism with respect to clinical end points, we used the Cholesterol And Recurrent Events (CARE) cohort. The CARE study was designed to investigate the effect of five years of pravastatin therapy on coronary events. RESULTS: We found that the odds ratios for the primary end point were not significantly different from unity for the three genetic subgroups after five years of placebo treatment. Furthermore, pravastatin induced similar changes in total cholesterol, low-density lipoprotein cholesterol, and HDL cholesterol among TaqIB genotypes, and both nonfatal myocardial infarction and deaths from coronary heart disease were reduced to the same extent in all three genotypes. CONCLUSIONS: In the CARE cohort, the CETP TaqIB polymorphism does not predict cardiovascular events or discriminate between those who will or will not benefit from pravastatin treatment.

Functional outcome after hip fracture. A 1-year prospective outcome study of 275 patients.

Two hundred and seventy-five consecutive patients over the age of 50 years admitted with a hip fracture were prospectively studied in detail, to assess the impact of a hip fracture on their functional ability and their need for social support. One hundred and eighty-three (66.9%) patients survived to 1 year. Mortality was highest amongst those least able to perform the recorded activities. One hundred and fifty-eight (86%) of the survivors were resident in the same level of accommodation after 1 year. There was a reduction in mobility and related functions of 20-25% and a reduction of 5% in tasks not related to hip function. It is therefore estimated that in the year after a hip fracture there will be decline in functionally abilities of about 5% unrelated to the hip fracture and about 15-20% directly related to the hip fracture. There was an increase in the requirement for social support amongst survivors individually, but overall the total economic burden on social services and institutional care was not significantly changed by hip fracture.

National outcomes of cataract extraction. Increased risk of retinal complications associated with Nd:YAG laser capsulotomy. The Cataract Patient Outcomes Research Team.

PURPOSE: The authors studied 57,103 randomly selected Medicare beneficiaries who underwent extracapsular cataract extraction in 1986 or 1987 to determine the possible association between performance of neodymium (Nd):YAG laser capsulotomy and the risk of subsequent retinal break or detachment. METHODS: Cases of cataract surgery were identified from Medicare claims submitted in 1986 and 1987 and were followed through the end of 1988. Episodes of cataract surgery, posterior capsulotomy, and retinal complications were ascertained based on procedure and diagnosis codes listed in physician bills and hospital discharge records. Lifetable and Cox's proportional hazards models were used to analyze the risk of retinal detachment or break in patients undergoing and not undergoing capsulotomy during the period of observation. RESULTS: Of the 57,103 persons identified as having undergone extracapsular cataract extraction in 1986 or 1987, 13,709 subsequently underwent Nd:YAG laser capsulotomy between 1986 and 1988. A total of 337 persons had aphakic or pseudophakic retinal detachments between 1986 and 1988 and an additional 194 underwent repair of a retinal break. Proportional hazards modeling shows a 3.9-fold increase in the risk of retinal break or detachment among those who underwent capsulotomy (95% confidence interval: 2.89 to 5.25). Younger patient age, male sex, and white race also were associated with increased risk of retinal complications after extracapsular cataract extraction. CONCLUSION: The authors conclude that there is a statistically significant increase in the risk of retinal detachment or break in those patients who undergo capsulotomy after cataract extraction. Therefore, capsulotomy should be deferred until the patient's impairment caused by capsular opacification warrants the increased risk of retinal complications associated with performance of capsulotomy.

Outcome-related health targets--political strategies for better health outcomes: a conceptual and comparative study (part 2).

Based on an analytical model which defines political co-ordinates on two axes (technocratic-participative and top-bottom), the policy documents of national and regional health target programmes in countries of the European Union, Australia, Canada, New Zealand and the USA are analysed in regard to the rationale for and interest in health targets, the involvement of actors in the policy-cycle, the setting of priorities, the distribution of responsibilities and accountability as well as incentives and sanctions used. Most, if not all, target programmes are conceptualised in a 'top-down' manner by the government and its administration with little involvement of the general public or the parliament. Usually, neither necessary alliances at the grass roots level nor appropriate incentives for local or professional actors are discussed in the documents. Many target programmes are, therefore, bound to fail and finding a balance between the right balance between technocratic and participative as well as between top and bottom remains a challenge for setting successful health targets.

Percutaneous coronary intervention versus coronary bypass graft surgery for diabetic patients with unstable angina and risk factors for adverse outcomes with bypass: outcome of diabetic patients in the AWESOME randomized trial and registry.

OBJECTIVES: This study compared survival after percutaneous coronary intervention (PCI) with survival after coronary artery bypass graft surgery (CABG) among diabetics in the Veterans Affairs AWESOME (Angina With Extremely Serious Operative Mortality Evaluation) study randomized trial and registry of high-risk patients. BACKGROUND: Previous studies indicate that CABG may be superior to PCI for diabetics, but no comparisons have been made for diabetics at high risk for surgery. METHODS: Over five years (1995 to 2000), 2,431 patients with medically refractory myocardial ischemia and at least one of five risk factors (prior CABG, myocardial infarction within seven days, left ventricular ejection fraction <0.35, age >70 years, or an intra-aortic balloon being required to stabilize) were identified. A total of 781 were acceptable for CABG and PCI, and 454 consented to be randomized. The 1,650 patients not acceptable for both CABG and PCI constitute the physician-directed registry, and the 327 who were acceptable but refused to be randomized constitute the patient-choice registry. Diabetes prevalence was 32% (144) among randomized patients, 27% (89) in the patient-choice registry, and 32% (525) in the physician-directed registry. The CABG and PCI survival rates were compared using Kaplan-Meier curves and log-rank tests. RESULTS: The respective CABG and PCI 36-month survival rates for diabetic patients were 72% and 81% for randomized patients, 85% and 89% for patient-choice registry patients, and 73% and 71% for the physician-directed registry patients. None of the differences was statistically significant. CONCLUSIONS: We conclude that PCI is a relatively safe alternative to CABG for diabetic patients with medically refractory unstable angina who are at high risk for CABG.
