Survey of nationally registered emergency medical services providers: pediatric education.

STUDY OBJECTIVE: To survey emergency medical services (EMS) providers on a national level to determine and describe their perspective regarding their initial and continuing education (CE) needs in pediatrics. METHODS: A 10-question survey was developed, pilot-tested, and sent to EMS providers as a part of their National Registry of Emergency Medical Technicians reregistration materials. RESULTS: Surveys were completed by 18,218 EMS providers, a response rate of 67%. During a typical month, 60% of emergency medical technician-paramedics (EMT-Ps), 84% of EMT-intermediates (EMT-Is), and 87% of basic EMTs (EMT-Bs) care for 0 to 3 pediatric patients. CE was identified by all provider levels as the main source of their pediatric knowledge and skills. A state or national mandate for required CE in pediatrics was supported by 76% of surveyed providers. More than 70% of all providers responded they were comfortable to some degree with their own ability and their EMS system's ability when confronted with a critical pediatric call. Cost, availability, and travel distance were identified by all levels as the primary barriers to obtaining pediatric CE. All levels identified infants as the age of greatest concern if the provider was called to manage a critical case. CONCLUSION: Surveyed practicing nationally registered EMS providers have infrequent contact with pediatric patients and have acquired most of their pediatric knowledge and skills from CE. In general, these providers are comfortable with their personal and their system's ability to care for children, but clearly support the need for required pediatric CE and identify the birth to 3-year age range as the priority for an educational focus. Cost, travel distance, and availability of pediatric CE are barriers that should be considered if pediatric CE is to be required of EMS providers.

Twenty-four-hour access to emergency care for children in managed care.

Children's medical emergencies occur around the clock. In years past, the emergency department, open 24 hours a day, was a familiar site for treating these emergencies. However, in today's health care environment, the scenario can be more confusing. As many families move from a fee-for-service system into a managed care organization (MCO), they may be unclear about what they should do in an emergency involving their child. MCOs want to provide appropriate care, and at the same time, operate within a system designed to contain costs through the establishment of effective health care delivery systems. Providers of emergency services, including specialists in pediatric medicine and emergency medical services responders, also must contend with a different set of problems, including administrative entanglements and concerns about reimbursement for their services. This article continues the white paper series by the Emergency Medical Services for Children Managed Care Task Force.

Spontaneous and stimulated growth hormone release in adolescents with type I diabetes mellitus: effects of metabolic control.

Abnormalities in GH release have been found in adults with poorly controlled type I diabetes mellitus. During puberty, circulating GH concentrations transiently increase. To investigate in pubertal diabetic adolescents, the physiological relationship between metabolic control and GH release, we compared spontaneous and GH-releasing hormone (GHRH)-stimulated GH release in six pubertal subjects during poor (study A) and improved (study B) metabolic control. The subjects included two females and four males (mean age +/- SE, 15.5 +/- 1 yr; duration of diabetes, 8.6 +/- 0.9 yr; Tanner stages II-V). Serum samples for glucose and GH determinations were obtained at 20-min intervals over a 24-h period. Significant pulses of GH release were identified using a pulse detection algorithm (Cluster). Fourier expansion time series was used to document the occurrence of significant periodicities in the GH concentration-time data series. All subjects received 1.0 microgram/kg GHRH-44, iv, at 0800 h on the day after the 24-h monitoring for GH. After GHRH administration, samples were taken for glucose and GH determinations over 90 min. The overall mean glucose level (+/- SE) during the 24-h monitoring was 11.5 +/- 0.2 mmol/L during study A and 7.2 +/- 0.2 during study B (P = 0.0001). During the 4 weeks of improved control, glycated hemoglobin fell from 13.9 +/- 1.4% to 11.7 +/- 0.8% (mean +/- SE; P < 0.025). All subjects had significant pulses of GH release during poor or improved metabolic control. Relative to that at night, the daytime pulse frequency was higher in study A (P < 0.025). The overnight pulse frequency increased during study B (P < 0.01). Other pulse parameters, including maximal and incremental pulse amplitudes, pulse width, and interpulse valley mean, did not change during improved control. The mean +/- SE 24-h GH concentration was 4.1 +/- 0.7 micrograms/L during study A and 4.3 +/- 0.8 during study B. The amplitude of the circadian GH rhythm was not different by Fourier analysis. The overall mean glucose +/- SE after GHRH administration was 15.3 +/- 0.2 mmol/L in study A and 6.8 +/- 0.1 in study B. In spite of the marked hyperglycemia during study A, the GH responses were similar during studies A and B. Maximal GH levels were obtained at 15-30 min (mean +/- SE) and were 36.0 +/- 16.9 micrograms/L in study A and 38.7 +/- 18.9 in study B.(ABSTRACT TRUNCATED AT 400 WORDS)

Policy alternatives for reducing tobacco sales to minors: results from a national survey of retail chain and franchise stores.

Minors' access to tobacco has become an important public health issue. Little is known, however, about the knowledge, attitudes, beliefs, and behavior toward access among executives from businesses that sell tobacco. This study examined access from the perspective of corporate and regional headquarters of retail chains and franchises that sell tobacco. A total of 148 U.S. companies with the largest overall retail sales volume that sold tobacco were asked to participate; 91 agreed. The sample included grocery stores, convenience stores, gas station mini-marts, liquor stores, and drug stores. Data revealed at least moderate support for policies limiting youth tobacco access. Although most companies reported having in place policies to prevent minors from purchasing tobacco, these policies did not seem intensive. In addition, executives underestimated the extent of youth access. We conclude that the time is right for passage of bold policies to protect young people from tobacco.

Obstacles to and future goals of ten comprehensive community health promotion projects.

Over 100 project staff, community coalition members, and other representatives from 10 comprehensive community health promotion projects in the western United States were surveyed two years into a three year funding cycle about: (1) the problems or obstacles they judged as preventing successful completion of their current goals and objectives, and (2) future goals and objectives they envisioned for their projects. The key issues confronting respondents were diverse, although issues around the process of implementing community health promotion programs were cited more frequently than issues related to the content of health promotion. When respondents were asked to prioritize Future Goals in the second survey, consensus across communities was obtained despite broad differences in the type of community surveyed and the health problem targeted. This study identifies the common organizational and community development problems faced by newly emerging community health promotion programs and has implications for other communities involved in designing, implementing, and evaluating community-wide health promotion programs.

An innovative strategy for institutionalizing a community-based tobacco program.

When Proposition 99 tobacco control program funding to state health departments was reduced in 1993, Contra Costa County developed a strategy to institutionalize its tobacco control programs in other organizations. This effort identified seven funding priorities and three stable, experienced community organizations "adopted" these priorities.
