Physicians specialties among

Not only does the absolute total number of prescriptions differ among physician specialities, but also the likelihood that one will receive a prescription from a given specialty varies, once the patient is seen in the provider s office. From the 1996 NAMCS database, Hoagwood et al. (2000) found that prescription prevalence rates vary among different providers 94.9% of visits by children with ADHD to family practitioners entailed the prescription of stimulants, while only 74.2% of such visits to psychiatrists and 75.4% of visits to pediatricians resulted in a stimulant prescription. Furthermore, while 14.8% of the visits to psychiatrists resulted in a nonstimulant prescription, only 1.9% of visits to family practitioners involved nonstimulant medication prescriptions. When considering the likelihood of any medication being prescribed (stimulants or nonstimulants) for a child with presumed ADHD, 11% of psychiatrist visits resulted in no prescription at... 

Thus, at the national level, the most is known about the stimulants, particularly methylphenidate, rather than other classes of medications. The various data sets, whether based on NAMCS, pharmacteutical industry sources (NDTl), or the several state-level Medicaid databases, indicate that most of the stimulant medications are currently prescribed by primary care providers. Zarin et al. (1998b), drawing on the NAMCS 1995 data, noted that among primary care, psychiatry, and other specialties (such as neurology), 12.4% of all ADHD medication-related visits in the sample were to a psychiatrist, 75.4% to primary care physicians, and 12.2% to other specialties. 

For decades orthopedics was a physical specialty. The physician provided therapy to manipulate bones and joints to restore alignment, and then applied casts or braces to maintain the structure until it healed. Fractures of the hip, among other injuries, were considered un-... 

Medical devices rely on knowledge from different sciences, from materials to electronics, mechanics or health among others. This wide scope forces the teaming up of different specialties from physicians to engineers (Santos and Tavares, 2013). As designs are driven by a current medical need, there may be a lack of information regarding requirements and specifications (Santos et al., 2012).
