Prioritization of professional issues by Idaho Dental Hygienists.
PURPOSE: The Idaho Dental Hygienists' Association (IDHA) and other constituents use surveys to establish the goals of the association and better represent members. This study was conducted to assess dental hygienists' opinions about professional issues related to dental hygiene practice and legislative activities in Idaho. METHODS: In 1998, a questionnaire was mailed to all active Idaho dental hygiene licensees (N = 652). The coded questionnaire contained two sections. Section I included items on demographic and employment characteristics, and Section II included items on legislative and professional issues. Respondents were asked to rank 14 professional issues by selecting the top five concerns about dental hygiene practice in Idaho. Research questions asked included: 1) Do entry-level baccalaureate degrees in dental hygiene affect the ranking of professional concerns of Idaho dental hygienists? 2) Does being a member of the American Dental Hygienists' Association (ADHA) affect Idaho dental hygienists' ranking of professional concerns? Data were analyzed using frequency distributions and nonparametric tests of association. RESULTS: A 74% (N = 431) response rate was obtained after two mailings. Three professional issues were ranked as important concerns by at least 50% of respondents. They were 1) the "national trend to reduce entry-level education for dental hygienists," 2) "dental assistants performing dental hygiene services," and 3) "legalizing self-regulation." CONCLUSIONS: It is incumbent upon constituent dental hygienists' associations to obtain and utilize information from members for strategic planning and legislative efforts. A statewide membership study clearly can provide direction. Idaho dental hygienists are concerned about maintaining quality education programs, reducing illegal practices, and regulating themselves. Also, the state association and regulatory agencies need to take an active role to assure that dentists, dental hygienists, and dental assistants are educated about state laws.

Total mercury levels in selected human tissues, Idaho-1973-74(1,2)
Total mercury levels were determined in human tissues taken at autopsy from six hospitals in the three basic geographical areas of Idaho. Of the 242 specimens analyzed, 76 percent contained detectable mercury. Levels were compared with respect to the age, sex, and geographic residence of autopsied individuals. Mean levels detected were 1.04 ppm in kidney tissue, 0.34 ppm in liver, and 0.08 ppm in brain. Mean mercury levels for the three geographical areas were: southeastern Idaho, 0.22 ppm; southwestern Idaho, 0.80 ppm; and northern Idaho, 0.43 ppm. The relatively high means in southwestern Idaho specimens may be related to the preponderance of natural cinnabar deposits in that portion of the State. Mercury levels were higher in women than men for all tissues in both the southwestern and northern areas, but the reverse was true in the southeast. Data were compared with findings of other investigators in an attempt to arrive at background levels of total mercury residues in human tissues.

Lead exposure and birth outcomes in five communities in Shoshone County, Idaho.
INTRODUCTION: This study examined birth outcomes in five towns in Shoshone County, Idaho, where residents were exposed to high levels of lead in air emissions during a 6-month period after a fire had damaged the main baghouse (pollution-control device) of a local lead smelter plant in September 1973. METHODS: We studied birth certificate data of 169,878 live singleton infants born to mothers who resided in Idaho at the time of delivery. The outcomes evaluated were preterm infants, small-for-gestational-age (SGA) infants, low birthweight among term infants (TLBW), and mean birthweight among term infants (TMBW). The study compared births in the five towns in Shoshone County (exposed group) to births in the rest of Idaho during three exposure periods: "pre-fire," January 1, 1970-August 31, 1973; "high exposure," September 1, 1973-December 31, 1974; and "post-fire," January 1, 1975-December 31, 1981. RESULTS: During the high-exposure period, the exposed group had an increased prevalence of TLBW (OR=2.4; 90% CI: 1.6-3.6) and SGA (OR=1.9; 90% CI: 1.3-2.8) compared with the rest of Idaho. During the pre- and post-fire periods, the ORs for TLBW were 0.8 and 1.3, respectively, and for SGA, 1.0, and 1.3, respectively. During the high-exposure period, TMBW for the exposed group was 71 g lower than in the comparison group. The TMBW in the exposed group was 8 g lower in the pre-fire period and 26 g lower in the post-fire period than in the comparison group. The study found no increased risk for preterm birth in the exposed group. CONCLUSIONS: Maternal exposures to airborne lead emissions appeared to be associated with increased risks for SGA, TLBW, and reduced TMBW.

High level waste tank closure project: ALARA applications at the Idaho National Engineering and Environmental Laboratory.
Bechtel BWXT Idaho, Maintenance and Operating Contractor for the Department of Energy at the Idaho National Engineering and Environmental Laboratory, has emptied, cleaned, and sampled six of the eleven 1.135 x 10(6) L high level waste underground storage tanks at the Idaho Nuclear Technology and Engineering Center, well ahead of the State of Idaho Consent Order cleaning schedule. Cleaning of a seventh tank is expected to be complete by the end of calendar year 2004. The tanks, with associated vaults, valve boxes, and distribution systems, are being closed to meet Resource Conservation and Recovery Act regulations and Department of Energy orders. The use of remotely operated equipment placed in the tanks through existing tank riser access points, sampling methods and application of as-low-as-reasonably-achievable (ALARA) principles have proven effective in keeping personnel dose low during equipment removal, tank, vault, and valve box cleaning, and sampling activities, currently at 0.03 Sv.

Idaho judge rebuffs abortion funding rule.
In a 3-page ruling on July 11, Ada County District Court Judge Duff McKee chastised Idaho officials for issuing new Medicaid regulations limiting abortion coverage to the same extent as an earlier rule found unconstitutional by the court. Judge McKee opened his order by calling the new rule "a blatant and ill-concealed attempt to maintain the status quo." Invalidating the prohibition on Medicaid coverage for low-income women's abortions except when two physicians certify that continued pregnancy will result in "grave, long-lasting physical damage," Judge McKee reiterated his holding that such a measure violates the Idaho Constitution. On February 1, Judge McKee held that the state Constitution provides broader protection for the right of privacy than the federal Constitution. The court indicated that the initial Medicaid regulation conflicted with a constitutional guarantee of neutrality, which requires Idaho to be evenhanded when subsidizing the exercise of a constitutionally protected right. Plaintiffs in Roe v. Harris--represented by ACLU Reproductive Freedom Project's Louise Melling, Planned Parenthood Federation's Carole Chervin, and cooperating attorney Newal Squyres--challenged the new regulation in early July. The lawsuit was originally filed in August of 1993. An Idaho statute, which was challenged but upheld, provides Medicaid funding when two physicians certify that it is necessary to save the woman's life or health, or when a court determines the pregnancy resulted from rape or incest.

Development of macroinvertebrate-based index for bioassessment of Idaho rivers.
Theoretical constructs, such as the river continuum concept, predict that the composition of benthic fauna in rivers will be different from that of headwater streams. There exists a need to modify, for use on larger rivers, the bioassessment techniques commonly used on small streams. Using aquatic macroinvertebrates and the "reference condition" approach, we developed and tested a multimetric index for use on the rivers of Idaho. Reference sites were selected to represent the best current conditions (i.e., least impacted) among Idaho rivers. The index performed well in distinguishing reference sites from sites displaying some form of anthropogenic impairment. Individual metrics used in the index included: number of EPT taxa, total number of taxa, percent dominant taxon, percent Elmidae, and percent predators. The index we developed for Idaho rivers was essentially a modification of a framework designed for small streams, suggesting that techniques, including data analysis, currently used for streams can be adapted for use on larger rivers. Adapting these methods for use in rivers is primarily a matter of (1) selecting metrics relevant to the rivers of interest; (2) expanding the field sampling to encompass the greater habitat area and, potentially, heterogeneity of rivers; and (3) selecting an appropriate form of data analysis. The approach we describe here should be applicable to geographic regions other than Idaho.

Concentrations of metals in mink and other mammals from Washington and Idaho.
From 1981 to 1983, concentrations of metals were determined in mink Mustela vison, muskrats Ondatra zibethica, and small mammals at one contaminated site in Idaho and at two less contaminated sites in Idaho and Washington. The highest concentrations of Pb and Cd occurred in samples from the Coeur d'Alene River system near or downstream from an extensive mining-smelting complex in northern Idaho. Maximum concentrations of Pb in the liver of a mink (22 microg g(-1)) and in pooled liver samples of both voles (Microtus spp., 5.8 microg g(-1)) and deer mice (Peromyscus maniculatus, 10.5 microg g(-1)) were higher than those inducing serious problems, including mortality, in experimental mammals on Pb-contaminated diets. Concentrations of Cd, Cu, Hg, and Zn were generally low. Declines in certain mammal populations have probably occurred in northern Idaho as a result of direct toxicity of metals and associated secondary effects on cover and food supply.

Medical waste treatment and disposal methods used by hospitals in Oregon, Washington, and Idaho.
This study investigated medical waste practices used by hospitals in Oregon, Washington, and Idaho, which includes the majority of hospitals in the U.S. Environmental Protection Agency's (EPA) Region 10. During the fall of 1993, 225 hospitals were surveyed with a response rate of 72.5%. The results reported here focus on infectious waste segregation practices, medical waste treatment and disposal practices, and the operating status of hospital incinerators in these three states. Hospitals were provided a definition of medical waste in the survey, but were queried about how they define infectious waste. The results implied that there was no consensus about which agency or organization's definition of infectious waste should be used in their waste management programs. Confusion around the definition of infectious waste may also have contributed to the finding that almost half of the hospitals are not segregating infectious waste from other medical waste. The most frequently used practice of treating and disposing of medical waste was the use of private haulers that transport medical waste to treatment facilities (61.5%). The next most frequently reported techniques were pouring into municipal sewage (46.6%), depositing in landfills (41.6%), and autoclaving (32.3%). Other methods adopted by hospitals included Electro-Thermal-Deactivation (ETD), hydropulping, microwaving, and grinding before pouring into the municipal sewer. Hospitals were asked to identify all methods they used in the treatment and disposal of medical waste. Percentages, therefore, add up to greater than 100% because the majority chose more than one method. Hospitals in Oregon and Washington used microwaving and ETD methods to treat medical waste, while those in Idaho did not. No hospitals in any of the states reported using irradiation as a treatment technique. Most hospitals in Oregon and Washington no longer operate their incinerators due to more stringent regulations regarding air pollution emissions. Hospitals in Idaho, however, were still operating incinerators in the absence of state regulations specific to these types of facilities.

Iodine-129 in rabbit thyroids near a nuclear fuel reprocessing plant in Idaho.
Thyroids were collected from rabbits on and near the Idaho National Engineering Laboratory (INEL) Site in southeastern Idaho and analyzed for 129I and stable iodine, 127I. The 129I/127I atom ratios in rabbits collected on the INEL site were larger than ratios in rabbits from a control area. Maximum 129I/127I atom ratios (9.1 x 10(-4)) occurred near the Idaho Chemical Processing Plant (ICPP). Based on rabbit thyroid concentrations, the 129I appeared to be deposited primarily in the direction of the predominant winds from the ICPP, northeast and southwest. Dose rates from the 129I to thyroids of INEL rabbits varied from 0.1 to 260 muGy/y (0.01 to 26 mrad/y). Iodine-129 atmospheric releases from the ICPP appeared to have increased the 129I/127I atom ratios on and near the INEL site.

Acute stroke care at rural hospitals in Idaho: challenges in expediting stroke care.
CONTEXT: Thrombolytics are currently the most effective treatment for stroke. However, the National Institute for Neurological Disorders and Stroke criteria for initiation of thrombolytic therapy, most notably the 3-hour time limit from symptom onset, have proven challenging for many rural hospitals to achieve. PURPOSE: To provide a snapshot of stroke care at rural hospitals in Idaho and to investigate the experiences of these hospitals in expediting stroke care. METHODS: Using a standard questionnaire, a telephone survey of hospital staff at 21 rural hospitals in Idaho was performed. The survey focused on acute stroke care practices and strategies to expedite stroke care. FINDINGS: The median number of stroke patients treated per year was 23.3. Patient delays were reported by 77.8% of hospitals, transport delays by 66.7%, in-hospital delays by 61.1%, equipment delays by 22.2%, and ancillary services delays by 61.1%. Approximately 67% of hospitals had implemented a clinical pathway for stroke and 80.0% had provided staff with stroke-specific training. No hospitals surveyed had a designated stroke team, and only 33.3% reported engaging in quality improvement efforts to expedite stroke care. Thrombolytics (tPA) were available and indicated for stroke at 55.6% of the hospitals surveyed. CONCLUSIONS: Rural hospitals in Idaho face many difficult challenges as they endeavor to meet the 3-hour deadline for thrombolytic therapy, including limited resources and experience in acute stroke care, and many different types of prehospital and in-hospital delays.

"Immunization mobile" brings protection to children in southeastern Idaho.
The problem that needs to be addressed is the 58 percent immunity level among 2-year-olds in southeastern Idaho, a level created by the indifference or fear of parents. Southeastern Idaho has the highest birth rate of any region in the State, and this situation has created a large group of children susceptible to vaccine-preventable diseases. The mobile unit, which consists of a specially equipped motor home, allows easy access to immunizations for groups of children and their parents. A search of the computerized record system installed in the mobile unit can provide data on past immunizations for each registered child. The target audience for the mobile unit's visits is church groups because of the particular cultural demographics of this region. In 1987, the District Seven Health Department, a State- and county-funded agency, expects to increase the number of doses of vaccine given by 3,000 over the 19,953 given in 1986. The "Shots for Tots" program is unique in the State of Idaho. Its expansion may be anticipated as the unit becomes better known in the region. The alternative to using aggressive, innovative techniques to motivate people to become immunized is disease.

Outbreak of trichinellosis associated with eating cougar jerky--Idaho, 1995.
On March 3, 1995, the Idaho Department of Health and Welfare received a report from the North Central District Health Department (NCDHD) of trichinellosis in a man residing in Idaho County, Idaho (1994 population: 14,938). This report summarizes the epidemiologic and laboratory investigations of this index case and the related outbreak by NCDHD, the U.S. Department of Agriculture (USDA), and CDC.

Future Land Use and Concerns About the Idaho National Engineering and Environmental Laboratory: A Survey of Urban Dwellers.
/ We examined environmental concerns and future land-use preferences of 487 people attending the Boise River Festival in Boise, Idaho, USA, about the Idaho National Engineering and Environmental Laboratory (INEEL), owned by the US Department of Energy (DOE). We were particularly interested in the perceptions of urban dwellers living at some distance from the facility, since attitudes and perceptions are usually examined for people living near such facilities. More than 50% of the people were most worried about contamination and about waste storage and transport, another 23% were concerned about human health and accidents and spills, and the rest listed other concerns such as jobs and the economy or education. When given a list of possible concerns, accidents and spills, storage of current nuclear materials, and storage of additional nuclear materials were rated the highest. Thus both open-ended and structured questions identified nuclear storage and accidents and spills as the most important concerns, even for people living far from a DOE site. The highest rated future land uses were: National Environmental Research Park, recreation (including hiking, camping, fishing and hunting), and returning the land to the Shoshone-Bannock tribes; the lowest rated future land uses were homes and increased nuclear waste storage. These relative rankings are similar to those obtained for other Idahoans living closer to the site and for people living near the Savannah River Site, another DOE facility in South Carolina. The concern expressed about accidents and spills and waste storage translated into a desire not to see additional waste brought to INEEL and a low rating for using INEEL for building homes.KEY WORDS: Future land use; Perceptions; Recreation; Hazardous waste; Department of Energy; Idaho National Engineering and Environmental Laboratory.http://link.springer-ny.com/link/service/journals/00267/bibs/24n4p532.html</HEA

Risk concerns, land use, stewardship, and the Idaho National Engineering and Environmental Laboratory: attitudes of the Shoshone-Bannock and other American Indians.
This paper examines the attitudes and perceptions of 277 American Indians about hunting and fishing, risk, and future land use of the Idaho National Engineering and Environmental Laboratory (INEEL) in southeastern Idaho. Nearly half of our sample were Shoshone-Bannock tribal members living on the nearby Fort Hall Reservation, and half were American Indians from elsewhere in the western United States. We also interviewed an additional 44 White people. We examine the hypothesis that there are differences in environmental concerns and attitudes toward future land use at IN-EEL as a function of tribal affiliation (ethnicity), educational level, gender, and age. Such perceptions are important because of the existence of tribal treaties that govern the legal and cultural rights of the Shoshone-Bannock. Returning INEEL to the Shoshone-Bannock Tribes, hunting, fishing, camping, hiking, and a National Environmental Research Park ranked as the highest preferred future land uses, whereas continuing nuclear materials reprocessing and increasing the storage of nuclear wastes ranked as the lowest. There were tribal differences in land use preferences, with those of the Fort Hall Indians being more similar to those of the local Whites than to other American Indians. All groups ranked storage of nuclear material, storage of additional nuclear material, and spills and accidents as the most serious of a list of concerns provided about the site. Fort Hall Indians answered an open-ended question with concerns for population levels and migration routes of game animals and other wildlife, more than hunting and human health. The Shoshone-Bannock from Fort Hall showed an environmental sensitivity for the well-being of wildlife and the health of the ecosystem and were interested in long-term stewardship, in addition to 29 concern for human health.

Lead toxicosis in tundra swans near a mining and smelting complex in northern Idaho.
Die-offs of waterfowl have occurred in the Coeur d'Alene River system in northern Idaho since at least the early 1900's. We investigated causes of mortality and lead and cadmium contamination of 46 tundra swans (Cygnus columbianus) from 1987 to 1989; an additional 22 swans found dead in 1990 were not examined. We necropsied 43 of the 46 birds found from 1987 to 1989; 38 of these were from the Coeur d'Alene River system, which has been contaminated with mining and smelting wastes for a century, and the other 5 were from a nearby, relatively uncontaminated area. Of the 36 livers of swans from the contaminated area that were analyzed, 32 contained lethal levels of lead (6 to 40 micrograms/g, wet weight) and all birds exhibited several symptoms of lead poisoning, notably enlarged gall bladders containing viscous, dark-green bile. Only 13% of the lead-poisoned birds (10% when data were included from other studies of swans in the area) contained shot, compared to 95% of lead-poisoning swans in studies outside northern Idaho. Lead concentrations in blood samples from 16 apparently healthy swans (0.5 to 2.3 micrograms/g, and 4 lead-poisoned birds found moribund (1.3 to 9.6 micrograms/g) indicating that tundra swans accumulated high levels of lead from ingestion of sediment that contained up to 8,700 micrograms/g of lead and plants that contained up to 400 micrograms/g. The swans spend only a few weeks in the area staging during the spring migration. The five tundra swans from the uncontaminated area had low levels of lead and essentially no symptoms of lead poisoning.(ABSTRACT TRUNCATED AT 250 WORDS)

Seasonal variations of lead concentration and loading rates in residential house dust in northern Idaho.
Although lead hazards to humans have been known since ancient times and many regulatory actions and lead risk reductions have been achieved over the past century, lead contamination and exposure remain significant problems worldwide. The focus of this study was to investigate whether residential house dust lead concentrations and lead and dust loading rates in non-contaminated or "background" communities in northern Idaho are significantly affected by seasonal variations. House dust samples were obtained from 34 houses in five towns of northern Idaho from March to November 1999. There was evidence of significant seasonality of lead concentration in house dust in some towns, but no evidence in other towns. Because of the high variability between the towns and small sample sizes, it was difficult to make firm conclusions about seasonal patterns observed in house dust lead levels. A linear relationship between precipitation rates and dust loading rates was detected.

Factors affecting retirement migration to Idaho: an adaptation of the amenity retirement migration model.
The purpose of this study was to determine factors affecting retirement migration of older persons, using Haas and Serow's (1993) model as the framework. Data were based on 462 persons aged 50 and older who had migrated to Idaho and surrendered their out-of-state drivers' licenses during 1992 and 1993. Most moved from another state in the west and were motivated to move to Idaho by such factors as outdoor recreation and quality and pace of life. They had visited their new community at least five times before moving and developed social ties quickly upon arriving. Businesses and community planners can more effectively anticipate changes necessary to accommodate older migrants to their community.
