Mandate for creation of a national peripheral arterial disease public awareness program: an opportunity to improve cardiovascular health.

BACKGROUND: There has been increasing recognition of the detrimental effect of peripheral arterial disease (PAD) on the health of Americans, and yet there is no common national program of public PAD education designed to diminish this effect. FORMAT: To heighten awareness of this problem, a 2-day PAD Public Education Strategy Meeting was recently attended by representatives of 17 professional societies and public health associations whose missions support the prevention, diagnosis, treatment, and rehabilitation of vascular diseases. This Public Education Strategy Meeting was intended to provide the rationale and structure to create a national PAD public awareness campaign to diminish the health effect of PAD and to improve cardiovascular outcomes in the United States. This document (1). provides the rationale for creation of a national PAD public education program; (2). reviews the development and success of national hypertension, hypercholesterolemia, and Women's Heart Health public education programs as models of educational efficacy; (3). elucidates how the work of many vascular professionals has led to a national consensus for creation of a national PAD public educational program; (4). provides an overview of the National Heart, Lung, and Blood Institute PAD education meeting; and (5). outlines the "next steps" required to accomplish these goals. OUTCOME: This meeting achieved consensus that we share responsibility for developing accurate, unified messages to promote PAD awareness and improved care. Participants agreed that the creation of such messages should be linked to plans to disseminate them to all Americans at risk. A consensus was reached that such messages, when commonly created and offered to the public, are most likely to achieve the rewards in better health that all Americans deserve. The Vascular Disease Foundation, a not-for-profit foundation whose mission includes public education about the prevention, diagnosis, treatment, and rehabilitation of PAD, will devote its resources to guide a new coalition in this process and to create a national PAD awareness campaign. During 2003 and 2004, the coalition will create the organizational underpinnings and time line for what will undoubtedly be a multiyear effort. CONCLUSION: Participants of the Public Education Strategy Meeting agreed to create a broad coalition to develop a National PAD Public Awareness Program, with the objectives to develop and disseminate public education massages on PAD. A successful national PAD education program will contribute to creation of a broader mandate to improve global cardiovascular health in the United States.

Urinary tract infection in persons with spinal cord injury.

Persons with spinal cord injury (SCI) have an increased risk of developing urinary tract infections. Certain structural and physiological factors, such as bladder over-distention, vesicoureteral reflux, high-pressure voiding, large post-void residuals, stones in the urinary tract, and outlet obstruction increase the risk of infection. The method of bladder drainage also influences the risk of urinary tract infection, and most persons with SCI on indwelling or intermittent catheterization develop urinary tract infection. The association of behavioral and demographic factors with the risk of urinary tract infection are less well understood. The method of specimen collection must be considered when determining the significance of bacteria. A national consensus conference sponsored by the National Institute on Disability and Rehabilitation Research defined significant bacteriuria as: > or = 10(2) colony forming units (cfu) of uropathogens per milliliter of urine in catheter specimens from persons on intermittent catheterization; > or = 10(4)cfu/mL in clean-voided specimens from catheter-free males using condom catheters; and any detectable concentration of uropathogens in indwelling catheter or suprapubic aspirate specimens. Symptomatic urinary tract infection warrants therapy, but the diagnosis is complicated by the poor sensitivity and specificity of symptoms and signs. Pyuria is generally present in persons with symptomatic urinary tract infection, although it is a nonspecific test, and its absence generally indicates the absence of symptomatic urinary tract infection. Treatment of asymptomatic bacteriuria has not been shown to be beneficial and increases the risk of development of antimicrobial-resistant uropathogens. Antibiotic prophylaxis is generally not recommended because of its unproven benefit in several studies and its association with emergence of antimicrobial resistance.(ABSTRACT TRUNCATED AT 250 WORDS)

Antenatal corticosteroids revisited: repeat courses - National Institutes of Health Consensus Development Conference Statement, August 17-18, 2000.

OBJECTIVE: To provide health care providers, patients, and the general public with a responsible assessment of currently available data regarding the benefits and risks of repeat courses of antenatal corticosteroids. PARTICIPANTS: A non-Federal, non-advocate, 16-member panel representing the fields of obstetrics and gynecology, pediatrics, maternal and fetal medicine, neonatology, medical ethics, community health, pharmacology, psychology, and reproductive biology. In addition, 13 experts in these same fields presented data to the panel and to a conference audience of approximately 200. EVIDENCE: The literature was searched using MEDLINE and an extensive bibliography of references was provided to the panel. Experts prepared abstracts of their conference presentations with relevant citations from the literature. Scientific evidence was given precedence over clinical anecdotal experience. CONSENSUS PROCESS: The panel, answering predefined questions, developed their conclusions based on the scientific evidence presented in open forum and the scientific literature. The panel composed a draft statement that was read in its entirety and circulated to the experts and the audience for comment. Thereafter, the panel resolved conflicting recommendations and released a revised statement at the end of the conference. The panel finalized the revisions within a few weeks after the conference. The draft statement was made available on the World Wide Web immediately following its release at the conference and was updated with the panel's final revisions. CONCLUSIONS: The collective international data continue to support unequivocally the use and efficacy of a single course of antenatal corticosteroids using the dosage and interval of administration specified in the 1994 Consensus Development Conference report. The current benefit and risk data are insufficient to support routine use of repeat or rescue courses of antenatal corticosteroids in clinical practice. Clinical trials are in progress to assess potential benefits and risks of various regimens of repeat courses. Until data establish a favorable benefit-to-risk ratio, repeat courses of antenatal corticosteroids, including rescue therapy, should be reserved for patients enrolled in clinical trials.

Toward the ethical evaluation and use of maternal-fetal surgery.

BACKGROUND: Important clinical, social, and ethical questions are associated with the evaluation and use of surgical approaches aimed at correcting fetal anatomic abnormalities. In particular, the expansion of maternal-fetal surgery to ameliorate nonlethal fetal conditions has intensified the need to address issues about the adequacy of technology assessment and the safety of those who undergo these novel procedures. APPROACH: After discussions at a multidisciplinary conference, we reviewed the development and current practices of maternal-fetal surgery and analyzed the relevant ethical issues concerning the use of maternal-fetal surgery for nonlethal conditions, focusing on the correction of myelomeningocele. FINDINGS: Characterizing nonvalidated maternal-fetal surgery procedures as "innovative therapy" blurs the boundaries between research and therapy and creates uncertainty about the obligations of clinicians and researchers. Further, maternal-fetal surgery raises ethical issues related to maternal risks and benefits, informed consent, distinguishing lethal from nonlethal conditions, withholding unproven treatments, entrepreneurship, and prioritization. RECOMMENDATIONS: To help ensure that maternal-fetal surgery will be studied and eventually applied in a scientifically and ethically sound manner, we offer several recommendations. First, innovation in maternal-fetal surgery should be conducted and evaluated as research. Second, women must be considered research subjects in these trials. Third, the informed consent process must ensure adequate comprehension and genuine voluntariness in those considering participation. Fourth, discriminatory and fearful attitudes toward individuals with disabilities should be addressed explicitly prior to making a decision to proceed with maternal-fetal surgery in an attempt to correct such disabilities. Fifth, maternal-fetal surgery should not be performed for cosmetic indications unless and until there is reliable evidence that maternal-fetal surgery can be performed safely and that long-term side effects on women and their offspring are minimal. Sixth, centers of excellence should be established for conducting research and providing maternal-fetal surgery. Seventh, funding for research on maternal-fetal surgery should be considered in the context of societal needs.

Antenatal corticosteroids in pregnancies complicated by preterm premature rupture of membranes.

In 1994, the National Institutes of Health Consensus Development Conference on Antenatal Steroids recommended corticosteroids between 24 and 30-32 weeks' gestation in pregnancies complicated by preterm premature rupture of membranes (PROM). Since the Consensus Conference, the use of antenatal corticosteroids has increased to approximately 60% of potential treatment candidates. Some of the remaining 40% of pregnant candidates may go untreated because of concern that corticosteroids could increase the risk of neonatal infection. Using decision-analysis techniques, we compared the potential benefit of antenatal corticosteroids in reducing the incidence of severe intraventricular hemorrhage with the potential risk of increasing the rate of neonatal sepsis. Our analysis indicates that the benefit of a small decrease in severe intraventricular hemorrhage outweighs the potential harm of a large increase in the rate of neonatal sepsis. Therefore, we support the Consensus Conference panel's recommendation that antenatal corticosteroids be used in pregnancies complicated by preterm PROM.

Antenatal corticosteroids for fetal maturation in women at risk for preterm delivery.

The available data unambiguously support the beneficial, short-term fetal effects of antenatal corticosteroids in women at risk for preterm delivery. There are still several incompletely addressed questions, including the use of corticosteroids in women with preterm premature rupture of membranes, the optimal corticosteroid preparation to be used, and the impact of repeated dosing. These issues are discussed in this review from the perspective of recent scientific evidence on the mechanisms responsible for positive short-term effects on survival and possible harmful long-term effects.

The case for intensive dissemination: adoption of practice guidelines in the coronary care unit.

Medical practice guidelines are being embraced enthusiastically by subspecialty and government organizations, but although hundreds have been developed at great public and private expense, there are few examples of how they have improved the quality of care or reduced health care costs. This article reports documented experience in changing physician behavior after implementing medical practice guidelines in the coronary care unit without altering physician incentives or imposing the threat of sanctions. Guideline adoption did require significant attention to the implementation process, including endorsement of guidelines by local "opinion leaders," validation by local data, and an intensive and concurrent implementation strategy.

Management of hepatitis C: current and future perspectives.

Chronic hepatitis C is now a major cause of chronic liver disease, cirrhosis and hepatocellular carcinoma. In March 1997, the National Institutes of Health sponsored a Consensus Development Conference entitled "Management of Hepatitis C". The final statement from the Consensus Panel set forth clear, evidence-based guidelines and recommendations regarding the diagnosis, evaluation, prevention and therapy of hepatitis C. The conclusions of the Consensus Panel have been widely accepted and have brought some degree of uniformity to the management of hepatitis C. An important issue is how to keep such recommendations current in such a rapidly evolving area of medicine. In the 2 years since the Consensus Conference there have been important advances in the management of chronic hepatitis C. Two recommendations of the Consensus Panel deserve modification: first, on the clinical usefulness of genotyping of hepatitis C virus and second, on the optimal therapeutic regimen. Two large multicenter, prospective controlled trials have shown that the combination of alpha interferon with ribavirin provides higher sustained virologic responses than interferon alone and that optimal therapy is a 24-week course for patients with genotypes 2 and 3 and a 48-week course for patients with genotype 1. Furthermore, therapy can be stopped at 24 weeks if HCV RNA is still present. Many clinical challenges remain. Major current needs are for accurate means of assessing the grade and stage of disease, for the likelihood of disease progression and of response to therapy as well as for viral eradication by treatment. Also important are new therapies for hepatitis C that might be used alone or in combination with interferon and ribavirin; therapies that could be applied to a wide variety of patients, with different stages of disease and with other comorbitities.

Universal newborn screening for hearing loss: ideal vs. reality and the role of otolaryngologists.

In 1993 the National Institutes of Health Consensus Statement, Early Identification of Hearing Impairment in Infants and Young Children, recommended "universal screening for hearing impairment prior to three months of age." However, the decision to invoke screening programs that include all newborns remains highly controversial, even though such programs now exist in at least 60 hospitals in 18 states. Unfortunately, otolaryngologists in the United States have not been actively involved in this ongoing debate, despite the role of those in our specialty as "gatekeepers" of hearing loss in patients of all ages. In relation to identification of hearing loss in the neonatal period, we have abrogated our responsibility to other health care professionals. Otolaryngologists, this is your "wake up call."
