Attitudes of College Football Officials Regarding NCAA Mouthguard Regulations and Player Compliance 总被引:1,自引:0,他引:1
Dennis N. Ranalli DDS MDS Diana M. Lancaster PhD 《Journal of public health dentistry》1993,53(2):96-100
The National Collegiate Athletic Association (NCAA) mandates the use of brightly colored, intraoral mouth- guards by football players to reduce the frequency and severity of craniofacial and intraoral morbidity and mortality, and to enhance the ability of officials to observe player compliance. The purpose of this 12-question mail survey was to determine the attitudes of on-Held game officials regarding current NCAA mouthguard regulations and patterns of utilization by college football players. The sample consisted of all 50 Big East Football Conference officials; a response rate of 100 percent was achieved. Only 42 percent of the officials reported observing all players in compliance, and quarterbacks were identified by others as the least compliant group (52%). The majority (88%) indicated that the 1990 rule for brightly colored mouthguards had been beneficial to them in determining player compliance, and 52 percent reported that this rule had resulted in more frequent use by these athletes. Nearly all officials (96%) indicated that they would issue a warning for noncompliance to the player or coach, rather than charging a timeout for a violation as prescribed by NCAA regulations. The majority (70%) believe current enforcement is appropriate, but expressed the opinion that coaches should be held more accountable for player compliance. 相似文献

Problems related to inappropriate prescribing practices of physicians in general are well recognized. Dietary fluoride supplements have been implicated as one of the contributing factors in an increase in dental fluorosis. Inappropriate prescribing practices of providers have been cited as a major factor in this implication. Numerous studies of physicians and dentists have documented a lack of knowledge and inappropriate prescribing practices regarding fluoride supplements. The purpose of this paper is to identify barriers to changing fluoride-prescribing practices of health care providers and to suggest strategies for implementing change. To increase optimal and appropriate use of fluoride supplements, educational interventions are necessary for all user groups--detail men and women, physicians, dentists, pharmacists, nurse practitioners, dental hygienists, and the public. In addition, environmental supports for the educational activities in the form of policy, regulation, standards of care, and guidelines are recommended for consideration. 相似文献

AbstractThe paper provides an introduction to the regulatory landscape affecting a particular category of medical technology, namely standalone software—sometimes referred to as ‘software as a medical device’. To aid the reader’s comprehension of an often complex area, six case studies are outlined and discussed before the paper continues to provide detail of how software with a medical purpose in its own right can potentially be classified as a medical device. The reader is provided an appreciation of how to go about classifying such software and references to support the developer new to the field in locating detailed regulatory support documents and contact points for advice. 相似文献

Face shields are personal protective equipment devices that are used by many workers (e.g., medical, dental, veterinary) for protection of the facial area and associated mucous membranes (eyes, nose, mouth) from splashes, sprays, and spatter of body fluids. Face shields are generally not used alone, but in conjunction with other protective equipment and are therefore classified as adjunctive personal protective equipment. Although there are millions of potential users of face shields, guidelines for their use vary between governmental agencies and professional societies and little research is available regarding their efficacy. 相似文献

Yellow fever (YF) is regarded as the original hemorrhagic fever and has been a major public health problem for at least 250 years. A very effective live attenuated vaccine, strain 17D, was developed in the 1930s and this has proved critical in the control of the disease. There is little doubt that without the vaccine, YF virus would be considered a biosafety level 4 pathogen. Significantly, YF is currently the only disease where an international vaccination certificate is required under the International Health Regulations. Despite having a very successful vaccine, there are occasional issues of supply and demand, such as that which occurred in Angola and Democratic Republic of Congo in 2016 when there was insufficient vaccine available. For the first time fractional dosing of the vaccine was approved on an emergency basis. Thus, continued vigilance and improvements in supply and demand are needed in the future. 相似文献

The goal of public health is to promote the best possible health for the whole population. Public health issues are numerous and can be unbelievably complex in form, scope, and possible consequence. Most public health decisions involve assessing several different options, weighing the respective benefits and risks of those options, and making difficult decisions that hopefully provide the greatest benefit to the affected populations. Many risk management decisions involve a variety of societal factors which modify risk assessment choices. The purpose of this paper is to point out difficulties in making decisions that impact public health. The intent of such decisions is to improve public health, but as illustrated in the paper, there can be unintended adverse consequences. Such unplanned issues require continued attention and efforts for responsible officials in the protection of environmental public health. This article presents examples of such events, when in the past, it was necessary to assess and regulate a number of potentially hazardous chemicals commonly used as insecticides, gasoline additives, and wood preservatives. 相似文献
