Alaska telemedicine: growth through collaboration.
The last thirty years have brought the introduction and expansion of telecommunications to rural and remote Alaska. The intellectual and financial investment of earlier projects, the more recent AFHCAN Project and the Universal Service Administrative Company Rural Health Care Division (RHCD) has sparked a new era in telemedicine and telecommunication across Alaska. This spark has been flamed by the dedication and collaboration of leaders at he highest levels of organizations such as: AFHCAN member organizations, AFHCAN Office, Alaska Clinical Engineering Services, Alaska Federal Health Care Partnership, Alaska Federal Health Care Partnership Office, Alaska Native health Board, Alaska Native Tribal health Consortium, Alaska Telehealth Advisory Council, AT&T Alascom, GCI Inc., Health care providers throughout the state of Alaska, Indian Health Service, U.S. Department of Health and Human Services, Office of U.S. Senator Ted Steens, State of Alaska, U.S. Department of Homeland Security--United States Coast Guard, United States Department of Agriculture, United States Department of Defense--Air Force and Army, United States Department of Veterans Affairs, University of Alaska, and University of Alaska Anchorage. Alaska now has one of the largest telemedicine programs in the world. As Alaska moves system now in place become self-sustaining, and 2) collaborating with all stakeholders in promoting the growth of an integrated, state-wide telemedicine network.

Childhood cancer among Alaska Natives.
OBJECTIVE: The primary purpose of this study was to examine the occurrence of cancer in Alaska Native (AN) children (under age 20). Although several studies have compared differences in cancer incidence between white and black children, few have examined cancer among Alaska Natives/American Indians. We know of no published article describing cancer incidence in AN children. We compared our findings with those of American Indian children of New Mexico and of Alaska white children. Data on mortality, survival, and prevalence are also included. Alaska Native is the term used collectively for the inhabitants whose ancestors occupied the area before European contact of what is now the state of Alaska. Alaska Natives include Eskimo, Indian, and Aleut groups. Although the 3 major groups differ in culture, language, and probably genetics, there are similarities in numerous social and economic indicators. The Northern Eskimo of Alaska (Inupiat) are related to Canadian and Greenland Inuit. Indians in Alaska include Athabaskan (in the interior of the state), who share commonalities with Canadian Athabaskan as well as with Navajo and Apache in the southwestern United States. Tlingit, Haida, and Tsimshian groups reside primarily in the southeast panhandle of the state. The panhandle Indian groups are similar to those of British Columbia. METHODS: Data on cancer incidence are from the Alaska Native Tumor Registry, 1969-1996. We studied children under age 20 to make our results comparable to national data as presented in the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) Pediatric Monograph. Population data for AN are based on census data and Indian Health Service intercensal estimates. Data for US whites and New Mexico Indians are from the National Cancer Institute's SEER program. Calculations were made using SEERStat software. Data for Alaska whites are for the years 1996-2000. (The Alaska Cancer Registry has collected data for all Alaskans only since 1996). Odds ratios (ORs) of rates with 95% confidence intervals (CIs) were calculated. RESULTS: The rate among all AN children (both sexes) for all cancers combined is similar to that of US whites (OR: 1.0; 95% CI: 0.8-1.1). Examination of childhood cancer rates by ethnicity, however, reveal that rates are significantly lower for Indian (OR: 0.6; 95% CI: 0.4-0.8) but not significantly different for Eskimo or Aleut children. For most International Classification of Childhood Cancers groups, incidence rates for AN children are also similar to those of US whites. However, AN children are at significantly higher risk for hepatic tumors (OR: 13.1; 95% CI: 7.9-20.5), particularly hepatocellular carcinoma (OR: 43.8; 95% CI:24.4-75.1) and retinoblastoma (OR: 2.8; 95% CI: 1.3-5.3). By ethnic group, rates for hepatocellular carcinoma are significantly high only for Eskimo. Rates for all AN children are lower for neuroblastoma (OR: 0.1; 95% CI: 0.1-0.6) and lymphoma (OR: 0.5; 95% CI: 0.3-0.9), particularly Hodgkin's disease (OR: 0.2; 95% CI: 0.0-0.5). On the basis of 5 years of data, rates for Alaska white children do not seem to differ from those of US white children. Because of our findings of differences between AN and US whites, we reviewed data of other relevant populations, specifically American Indian data from the New Mexico SEER registry. Using SEER data and SEER software, we calculated rates for New Mexican American Indians (NMAI) and compared them with US white rates. Rates for all cancers combined among NMAI are significantly lower than for US white (OR: 0.8). However, similar to AN children, the rate among NMAI for retinoblastoma is higher compared with US whites (OR: 2.5; 95% CI:1.4-4.5). Similar to AN, NMAI also seem to be at low risk for neuroblastoma (OR: 0.2; 95% CI: 0.1-0.7), lymphoma as a group (OR: 0.1; 95% CI: 0.0-0.3), and, specifically, Hodgkin's disease (OR: 0.1; 95% CI: 0.0-0.4). Rates among NMAI children are low for central nervous system tumors (OR: 0.5; 95% CI: 0.3-0.7). The average annual age-adjusted cancer mortality rate among AN children is lower but not significantly lower than that of US white children (28.6 vs 37.3 per million). CONCLUSIONS: Comparison of AN rates for all cancers combined are similar to those of US and Alaska white children but seem higher than those of NMAI. Differences between AN and US whites exist for select International Classification of Childhood Cancers groups. The most striking rate differences are found in hepatic tumors, largely because of elevated rates of hepatitis B-associated hepatocellular carcinoma. All children in our study with hepatocellular carcinoma were hepatitis B antigen positive. A statewide hepatitis B virus immunization program was begun in late 1982. Although 16 children who were born before 1983 developed hepatocellular carcinoma, no children who were born in the 20 years since hepatitis B immunization was instituted among infants have received a diagnosis of hepatocellular carcinoma, a significant difference. Comparing AN and US white childhood cancer rates after removing hepatocellular carcinoma cases from both populations results in an OR of 0.8 (95% CI: 0.7-1.0). Thus, if no increase in other childhood cancers occurs in the coming generations, then rates for childhood cancer may soon be significantly lower than those in US white children. Rates are low for all lymphomas, largely because of very low rates of Hodgkin's disease. Rates are also low for neuroblastoma. It is reassuring that rates for AN children are not in excess and do not seem to be increasing. There is concern among the population regarding environmental exposure, including ionizing radiation. Our data do not show excess childhood leukemia or thyroid cancers, malignancies for which radiation is known to increase risk.

Prevalence of tobacco use among Alaska Natives: a review.
BACKGROUND: Previous reports documented high rates of tobacco use among Alaska Natives (Eskimos, Indians, and Aleuts). In this population, tobacco use is the leading preventable cause of death. Lung cancer is the leading cause of cancer death among Alaska Natives and tobacco is responsible for over one-third of all cancer deaths in this population. Until recently there has been no systematic surveillance of the prevalence of tobacco use in this high-risk population. Data that did exist were not readily available to those primarily responsible for the health care of this population. This is the first time since 1990 that data on Alaska Natives have been collected in one analysis; this permits a more representative evaluation of tobacco use. METHODS: Data on tobacco use were obtained and analyzed from national and state surveys and selected research projects from 1988 to 1993. RESULTS: Alaska Natives have high prevalence of tobacco use, including both cigarettes and smokeless tobacco. Tobacco use prevalence among Alaska Natives exceeds that of Alaska non-Natives, U.S. whites, and American Indians/Alaska Natives in the United States outside of Alaska. Smoking prevalence among Alaska Native women is twice that of non-Native women in Alaska and nearly twice as high among pregnant Alaska Natives than pregnant non-Natives. Overall, prevalence of smokeless tobacco use was four times higher among Alaska Natives than comparative state and national populations. CONCLUSION: Because this population has such high rates of tobacco use, it is important to public health that monitoring and educational programs be in place and that data specific to Alaska Natives be made available.

Educating medical students for Alaska.
Because Alaska does not have its own medical school, it has become part of WAMI (Washington, Alaska, Montana, Idaho), an educational agreement with the University of Washington School of Medicine (UWSM). Each year, 10 Alaskans are accepted into the entering class of UWSM and spend their first year at the University of Alaska Anchorage (UAA). UWSM third- and fourth-year medical students can obtain some of their clinical experience in Alaska. To meet the needs of Alaska, students are chosen based on academic and personal records, as well as the likelihood of their returning to Alaska for practice. To this end, over the last seven years 30% of accepted students have come from rural communities and 10% are Alaska Natives. The curriculum for the first year includes several sessions dedicated to Alaska health problems, cross-cultural issues, and Alaska's unique rural health care delivery system. Students do two preceptorships--one with a private primary care physician and one with a physician at the Alaska Native Medical Center. Additionally, students have the option to spend a week at a rural site to learn about the community's health care system. An Alaska track is being developed whereby an Alaskan UWSM student can do most of the third year in state via clerkships in family medicine, obstetrics/gynecology, psychiatry, internal medicine, and pediatrics. All UWSM students at the end of their first year can elect to participate for one month in the R/UOP (Rural/Underserved Opportunities Program), which includes several Alaska sites. The overall goals of these approaches are to educate UWSM students, especially Alaskans, about the state's health needs and health care system and to encourage UWSM graduates to practice in the state.

Alaska Natives assessing the health of their environment.
The changes in Alaska's ecosystems caused by pollution, contaminants and global climate change are negatively impacting Alaska Natives and rural residents who rely on natural resources for food, culture and community identity. While Alaska commerce has contributed little to these global changes and impacts, Alaska and its resources are nonetheless affected by the changes. While Alaska Natives have historically relied on Alaska's land, water and animals for survival and cultural identity, today their faith in the safety and quality of these resources has decreased. Alaska Natives no longer believe that these wild resources are the best and many are turning to alternative store-bought foods. Such a change in diet and activity may be contributing to a decline in traditional activities and a decline in general health. Contaminants are showing up in the animals, fish and waters that Alaska Natives use. Efforts need to be expanded to empower Alaska Native Tribes to collect and analyze local wild foods for various contaminants. In addition existing information on contaminants and pollution should be made readily available to Alaska residents. Armed with this type of information Alaska Native residents will be better prepared to make informed decisions on using wild foods and materials.

Severity and frequency of sequelae of bacterial meningitis in Alaska Native infants. Correlation with a scoring system for severity of sequelae.
OBJECTIVES: To (1) determine the frequency and severity of sequelae of Haemophilus influenzae type b and Streptococcus pneumoniae meningitis in Alaska Native children, (2) compare morbidity and mortality of H influenzae b and S pneumoniae meningitis, and (3) evaluate the applicability of the Herson-Todd prognostic score (HTPS) to both H influenzae b and S pneumoniae meningitis in this population. DESIGN: A retrospective study of all cases of H influenzae b and S pneumoniae meningitis in Alaska Native children younger than age 5 years. Data on meningitis sequelae, obtained from medical charts and records of the Infant Learning Program, were collected, and incidence of sequelae tabulated. Data obtained on admission to the hospital were used to calculate HTPS. SETTING: Indian Health Service facility for the Yukon-Kuskokwin Delta region of southwest Alaska. STUDY SUBJECTS: 51 of 63 Alaska Native children with H influenzae b meningitis and 13 of the same 63 Alaska Native children with S pneumoniae meningitis occurring between 1980 and 1988. One child was infected with both organisms, producing a total of 64 cases for study. SELECTION PROCEDURES: Cases were identified by surveillance for these diseases between January 1, 1980, and December 31, 1988, maintained by the Arctic Investigations Program, Centers for Disease Control. MEASUREMENTS AND RESULTS: Sequelae of bacterial meningitis caused by H influenzae b were equal to or exceeded rates of sequelae described in other children in the United States. After H influenzae b meningitis, motor abnormalities (29%) and hydrocephalus (7%) occurred two to four times more often in Alaska Native children than in children in other parts of the United States. Differences in severity of H influenzae b sequelae could not be accounted for by microbiologic markers of the H influenzae b strain, including ampicillin sensitivity, biotype, outer membrane protein type, or electropherotype. Numbers of cases of S pneumoniae meningitis were too small for statistically valid comparison, but sequelae of S pneumoniae meningitis occurred in roughly equal proportion as sequelae of H influenzae b meningitis. The HTPS was applied to Alaska Native children with H influenzae b meningitis and was found to be very accurate in predicting children with major sequelae. Analysis of the prognostic factors used in deriving the HTPS revealed a unique set of predictors for sequelae in Alaska Native children: seizures at admission, glucose levels in cerebrospinal fluid of less than 1.1 mmol/L; and male gender, with a significant predictive interaction between male gender and age less than 6 months at admission. CONCLUSIONS: Alaska Native children suffer greater neurologic morbidity as a result of H influenzae b meningitis than do their non-Native counterparts. The HTPS was a good predictor of major sequelae in Alaska Native children with H influenzae b or S pneumoniae meningitis and could be useful in determining which patients need referral to a tertiary care center.

Asthma prevalence among Alaska Native and nonnative residents younger than 20 years enrolled in Medicaid.
BACKGROUND: No study of childhood asthma prevalence in Alaska or among Alaska Natives has been conducted. OBJECTIVE: To determine asthma prevalence among Alaska Medicaid enrollees younger than 20 years, with an emphasis on Alaska Natives, the state's largest minority and predominant rural citizens. METHODS: A master database was obtained that included all children enrolled in Medicaid during July 1998 through June 1999. Physician, pharmacy, and hospital claims files for International Classification of Diseases codes 493.0x to 493.9x were linked to this master database. Asthma was defined as any asthma-related care or medication claim. RESULTS: Asthma prevalence among the study population was 6.9%. Alaska Natives had a lower asthma prevalence than nonnatives (risk ratio [RR], 0.70; 95% confidence interval [CI], 0.66-0.75), but among the subgroup of children residing in the state's major urban center, Alaska Natives had a higher prevalence. Overall, 0.22% of the study population experienced an asthma-related hospitalization, with Alaska Natives having a higher risk of hospitalization than nonnatives (RR, 1.6; 95% CI, 1.2-2.3). Among hospitalized children, Alaska Natives were less likely to have received a long-term control medication (RR, 0.54; 95% CI, 0.33-0.88). CONCLUSIONS: Compared with nonnatives, Alaska Natives have a lower risk of asthma but only among nonurban residents. The increased risk of hospitalization among Alaska Natives may be related to underuse of long-term control medications.

Colorectal cancer incidence and survival among Alaska Natives, 1969-1993.
BACKGROUND: Although colorectal cancer rates are low among most groups of Native Americans in North America, rates for Alaska Natives have been substantially elevated compared with US rates for all races combined. METHODS: To better describe the epidemiology of colorectal cancer incidence and survival among Alaska Natives, stratified by gender and tribal/ethnic affiliation, we examined data collected by the Alaska Native Cancer Registry 1969-1993. We calculated age-adjusted and age-specific incidence as well as actuarial survival rates, and examined histological type, site, stage at diagnosis, and treatment. We compared these data to colorectal cancer data from whites living in western Washington. RESULTS: In all, 587 colorectal cancer cases were identified among Alaska Natives over the 25-year period, for an age-adjusted annual incidence rate of 71.4/100000 in women, and 69.3/100000 in men. Compared to Alaska Indians, colon cancer rates were significantly higher in Aleuts (relative risk [RR] = 1.6, 95% CI: 1.2-2.2) and in Eskimos (RR = 1.5, 95% CI: 1.2-1.8), while rectal cancer rates did not differ by race/ethnicity. Alaska Natives experienced a 50% higher incidence rate of colorectal cancer overall compared to western Washington whites (RR = 1.5, 95% CI: 1.3-1.6), although rectal cancer rates were similar in the two populations. The highest RR were seen among Alaska Native women; Aleuts and Eskimos had colon cancer rates more than twice that of western Washington white women. No unusual qualitative features were found in the cancers occurring in Alaska Natives. Actuarial colorectal cancer survival rates for Alaska Natives overall were 74% at one year and 42% at 5 years; these rates were very similar to those observed for the western Washington population. Both one and 5-year survival rates showed a significant trend towards improvement over time. CONCLUSIONS: Alaska Natives had substantially higher colorectal cancer incidence rates compared to western Washington whites. Rates were particularly high for Aleut and Eskimo women. These data suggest a need for intensified secondary prevention strategies for this high-risk population, while further research is needed to identify modifiable risk factors.

Health care delivery for Alaska Natives: a brief overview.
OBJECTIVES: Describe the Alaska Native Health Care delivery system and some of the historical elements that shaped it. STUDY DESIGN: Retrospective program review. METHODS: Retrospective review of existing administrative and clinical programs. RESULTS: Over the last 10,000-15,000 years the Alaska Native Health System developed from at traditional tribal based self-care system to a complex system that is interdependent on local, state, federal, and private insurance payers. The Alaska Tribal Health System takes an intentional approach to planning. While the system may face an uncertain future, it is poised to continue it remarkable success. The regional health corporations are the backbone of the system and it is the regional health corporations that own the Alaska Tribal Health System. In addition, it is the Alaska Tribal Health System that is responsive to the needs and priorities of the regional health corporations and their Native constituents. The spirit of the Alaska Native has inspired their health care providers at all levels to develop innovative "work arounds" to provide state of the art care through regionalization and telemedicine. Despite the many challenges ahead, the Alaska Tribal Health System will continue to strive to increase the health of Alaska Native people to the highest status possible. CONCLUSION: The Alaska Native health care system is a dynamic system administered by and for Alaska Native peoples. This system has risen to many challenges in the past and has made great strides through both ingenuity and necessity.

Racial differences in birthweight-specific neonatal mortality in Alaska: 1987-1996.
OBJECTIVES: This study compared the neonatal mortality in the Alaska Native and non-native (primarily white) population in Alaska for a 10-year period (1987-1996). METHODS: Natality, mortality, and cause of death data were obtained from the State of Alaska's Bureau of Vital Statistics (BVS). Birthweight-specific and preventable birthweight-specific mortality were analyzed for babies < 1500 grams, 1500-2499 grams, and > or = 2500 grams birthweight. RESULTS: The low birthweight (LBW) and very low birthweight (VLBW) rates were similar for the Alaska Native and non-native populations. The neonatal mortality rate for the Alaska Native population was higher than for the non-native population (6.4 per 1,000 live births for Alaska Native vs. 4.1 for non-native for 1987-1991; 5.5 for Alaska Native vs. 3.5 for non-native for 1992-1996). Birthweight-specific mortality was higher in the Alaska Native population for all birthweight groups. The exclusion of non-preventable conditions accentuated the differences in mortality rates between the Alaska Native and non-native population for infants < 2500 grams birthweight. CONCLUSION: The higher neonatal mortality in the Alaska Native population is associated with a higher overall and preventable birthweight-specific neonatal mortality. The differences are therefore likely to reflect differences in access to and quality of perinatal care.

Infant mortality in Alaska: evidence of high postneonatal mortality rate.
Improvements in infant mortality (death less than 1 year of age) have been experienced by the United States and Alaska over the past decade. The decline in the Alaska neonatal mortality (death less than 28 days of age) rate has been the major factor in our improved infant mortality rate. Alaska's neonatal mortality rate is one of the lowest in the U.S. However, postneonatal mortality (28 days to 1 year of age) rate has not declined and is one of the highest in the U.S. In this study we used vital statistics records to examine socio-demographic and inter-regional factors that may help to explain Alaska's apparently high postneonatal mortality rate. The study population consisted of all live born infants in Alaska for 1975 to 1985, who died in infancy. The Alaska neonatal mortality rate has been lower, but postneonatal mortality rate has been higher than the U.S. average for the period under consideration (p less than .05). Comparison of alaska postneonatal mortality rate from 1975 to 1985 with the U.S. found Alaska Non-natives have higher postneonatal mortality rates than U.S. White, and Alaska Native have higher postneonatal mortality rates than other U.S. minorities. The rural areas of Alaska have a higher postneonatal mortality rate than urban areas, a phenomenon also observed for the U.S. as a whole.

Establishing a culturally sensitive palliative care program in rural Alaska Native American communities.
End-of-life programs that provide an option for patients to die at home are available in most U.S. communities. However, Alaska Natives living in remote Alaska villages often die alone in hospitals and nursing homes hundreds of miles away from home. The Bristol Bay Area Health Corporation (BBAHC), a tribal organization, is the sole provider of comprehensive primary care services to 34 Alaska Native villages located within a 46,000 square mile area in southwest Alaska. The closest tertiary care hospital is 329 air miles away in Anchorage. Because of the high cost of, and difficulties encountered in trying to deliver end-of-life care services to remote communities, a village-focused, culturally sensitive, volunteer and primary care program combined with a regionally based physician and home health nurse to deliver multi-disciplinary palliative care was developed. The Helping Hands Program blends cultural practices with contemporary palliative care medicine to allow Alaska Natives and others living in remote communities to be cared for at home through the end of life. Since the program was implemented in 1999, the percentage of home deaths for selected causes has changed from 33% in 1997 to 77% in 2001. The Anchorage-based Alaska Native Tribal Health Consortium (ANTHC) and the Alaska Native Medical Center (ANMC) have recognized the importance and success of the BBAHC program and are investigating expanding the program to other parts of Alaska. Centralizing the program in Anchorage will allow staff trained in palliative care to travel to regional Alaska Native hospitals to help train health care professionals.
