A political history of the Indian Health Service.

One of the few bright spots to emerge from the history of relations between American Indians and the federal government is the remarkable record of the Indian Health Service (IHS). The IHS has raised the health status of Indians to approximate that of most other Americans, a striking achievement in the light of the poverty and stark living conditions experienced by this population. The gains occurred in spite of chronically low funding and can be attributed to the combination of vision, stubbornness, and political savvy of the agency's physician directors and the support of a handful of tribal leaders and powerful allies in the Congress and the White House. Despite the agency's imperfections and the sizeable health problems that still exist among American Indians and Alaskan Natives, the IHS is an example of one federal program that has worked.

Injury hospitalizations among American Indian youth in Washington.

OBJECTIVE: To determine the rate and causes of hospitalizations for injury among American Indian and Alaska Native (AI/AN) youth in the state of Washington, and to compare this with the rate of hospitalizations for injury among youth of all races. METHODS: Subjects were aged 0-19 years and were admitted to civilian hospitals for care of an injury (International Classification of Diseases N codes 800-995) in Washington between 1990 and 1994. Deaths occurring in the prehospital setting and emergency department are not included. Using several fields of identifying information, the Washington state hospital discharge database was linked with the Indian Health Service (IHS) patient registration database to identify AI/AN youth. Denominator data included the total age specific IHS user population for American Indians and US Census derived population estimates. Incidence ratios (IRs) were calculated to compare rates of hospitalization between AI/AN youth and all youth in Washington. RESULTS: A total of 694 and 29,048 hospitalizations for injury were identified for AI/AN youth and all races, respectively. The rate of hospitalization for injuries among AI/AN youth was 507 discharges per 100,000 youth (IR = 1.30; 95% confidence interval (CI) 1.20 to 1.40. The leading mechanism of injury was motor vehicles (IR 1.73, CI 1.49 to 2.01), followed by falls (IR 0.95, CI 0.79 to 1.15), and poisoning (IR 1.20, CI 0.80 to 1.78). The disparity was greater for intentional injuries (IR 1.71, CI 1.44 to 2.04). The highest IR for all unintentional injuries was for injuries from fire (IR 2.35, CI 1.42 to 3.87). AI/AN children aged 15-19 had the greatest disparity for rates of injury hospitalization (IR 1.4, CI 1.25 to 1.56). CONCLUSION: AI/AN youth in Washington had a higher hospitalization rate for injury compared with all youth in the state. Disparities were greatest for injuries related to motor vehicles and assaults. When linked, hospital discharge data can be used for surveillance of AI/AN hospitalizations.

Handgun purchase trends, Washington state: differences by age of buyer.

STUDY OBJECTIVES: To examine trends in legal handgun purchases from federally licensed dealers and specifically to describe recent changes in age and gender of purchaser and caliber of handguns purchased. METHODS: A cohort study was performed of the adult population of Washington state from 1950 through 1992 using a state dealer record of handgun sales database. The purchase of handguns from licensed dealers was expressed as the number purchased per 100,000 population per year. RESULTS: The handgun purchase rate increased for the total population between 1950 and 1992, from 169 to 2,076 per 100,000 persons. Between 1983 and 1992, the purchase rate among men aged 21 to 24 years increased 184%; among women of this age group, the rate increased 127%. Among men aged 21 to 24 years, the rate of 9 mm handgun purchases increased 1,682% between 1983 and 1992, the greatest increase for any age-caliber category. CONCLUSION: The greatest increase in rate of legal handgun purchases in Washington state from 1983 through 1992 was among the youngest purchasers. Sales of 9 mm handguns increased most rapidly, especially among the youngest buyers.

State gun safe storage laws and child mortality due to firearms.

CONTEXT: Since 1989, several states have passed laws that make gun owners criminally liable if someone is injured because a child gains unsupervised access to a gun. These laws are controversial, and their effect on firearm-related injuries is unknown. OBJECTIVE: To determine if state laws that require safe storage of firearms are associated with a reduction in child mortality due to firearms. DESIGN: An ecological study of firearm mortality from 1979 through 1994. SETTING: All 50 states and the District of Columbia. PARTICIPANTS: All children younger than 15 years. MAIN OUTCOME MEASURES: Unintentional deaths, suicides, and homicides due to firearms. RESULTS: Laws that make gun owners responsible for storing firearms in a manner that makes them inaccessible to children were in effect for at least 1 year in 12 states from 1990 through 1994. Among children younger than 15 years, unintentional shooting deaths were reduced by 23% (95% confidence interval, 6%-37%) during the years covered by these laws. This estimate was based on within-state comparisons adjusted for national trends in unintentional firearm-related mortality. Gun-related homicide and suicide showed modest declines, but these were not statistically significant. CONCLUSIONS: State safe storage laws intended to make firearms less accessible to children appear to prevent unintentional shooting deaths among children younger than 15 years.

Effectiveness of a violence prevention curriculum among children in elementary school. A randomized controlled trial.

OBJECTIVE: To determine if a commonly used violence prevention curriculum, Second Step: A Violence Prevention Curriculum, leads to a reduction in aggressive behavior and an increase in prosocial behavior among elementary school students. DESIGN: Randomized controlled trial. SETTING: Urban and suburban elementary schools in the state of Washington. PARTICIPANTS: Six matched pairs of schools with 790 second-grade and third-grade students. The students were 53% male and 79% white. INTERVENTION: The curriculum uses 30 specific lessons to teach social skills related to anger management, impulse control, and empathy. MAIN OUTCOME MEASURES: Aggressive and prosocial behavior changes were measured 2 weeks and 6 months after participation in the curriculum by parent and teacher reports (Achenbach Child Behavior Checklist and Teacher Report Form, the School Social Behavior Scale, and the Parent-Child Rating Scale) and by observation of a random subsample of 588 students in the classroom and playground/cafeteria settings. RESULTS: After adjusting for sex, age, socioeconomic status, race, academic performance, household size, and class size, change scores did not differ significantly between the intervention and control schools for any of the parent-reported or teacher-reported behavior scales. However, the behavior observations did reveal an overall decrease 2 weeks after the curriculum in physical aggression (P=.03) and an increase in neutral/prosocial behavior (P=.04) in the intervention group compared with the control group. Most effects persisted 6 months later. CONCLUSIONS: The Second Step violence prevention curriculum appears to lead to a moderate observed decrease in physically aggressive behavior and an increase in neutral and prosocial behavior in school.

Motor-vehicle crash-injury risk factors among American Indians.

The rates of motor-vehicle crash mortality are highest among American Indians and Alaska Natives, compared to other ethnic groups. The aim of this study was to compare risk factors for motor-vehicle crashes and occupant injuries between rural and urban American-Indian (AI) drivers, and between rural AI and non-AI rural drivers. A statewide traffic-accident database was linked to the Indian Health Service patient-registration database to identify crashes that involved American-Indian drivers. Using a cross-sectional design, crashes occurring in a two-county region during 1989 and 1990 were studied. A total of 9329 motor-vehicle crashes involving 16,234 drivers and 6431 passengers were studied. Two percent of drivers were American Indian. Compared to American-Indian drivers in urban crashes, rural crashes involving American-Indian drivers were more likely to result in injury or death (38% vs 64% p < 0.001). The difference in risk for crashes between urban and rural non-AI drivers was not as high (42% vs 33%). Only 44 percent of rural American-Indian motor-vehicle occupants reported wearing seat belts, compared to 70 percent of urban American-Indian occupants (p < 0.05). Rates of driver alcohol impairment, as assessed by the police, were much higher among AI drivers and highest among rural AI drivers. We conclude that, compared to non-American-Indian drivers, AI drivers are less likely to be restrained and more likely to be alcohol-impaired at the time of the crash. These risks are higher among rural AI drivers than urban AI drivers.

Urban-rural differences in prehospital care of major trauma.

OBJECTIVES: To compare differences in response times, scene times, and transport times by advanced life-support-trained paramedics to trauma incidents in urban and rural locations. METHODS: This report was a prospective cohort study of professional emergency medical services conducted in a five-county area in the state of Washington. Ninety-eight percent of trauma transports are provided by professional paramedics trained in advanced life support. Subjects were included in this study if they qualified as a major trauma victim and were transported or found dead at the scene by one of the region's advanced life support transport agencies between August 1, 1991, and January 31, 1992. The severity of injury was rated using the Prehospital Index. Incident locations were defined as "rural" if they occurred in a US Census division (a geographic area) in which more than 50% of the residents resided in a rural location. RESULTS: During the 6-month data collection period, advanced life support agencies responded to a total of 459 major trauma victims in the region. A geographic locations was determined for 452 of these subjects. Of these, 42% of subjects were injured in urban areas and the remainder in rural areas. The severity of injuries, as determined both by the triage classification (p = 0.17) and the distribution of Prehospital Index scores (p = 0.92), was similar for urban and rural major trauma patients. Twenty-six (5.7%) subjects died at the scene. About one quarter of both groups had a severe injury, as indicated by Prehospital Index score of more than 3. The mean response time for urban locations was 7.0 minutes (median = 6 minutes) compared with 13.6 minutes (median = 12 minutes) for rural locations (p < 0.0001). The mean scene time in rural areas was slightly longer than in urban areas (21.7 vs. 18.7 minutes, p = 0.015). Mean transport times from the scene to the hospital were also significantly longer for rural incidents (17.2 minutes vs. 8.2 minutes, p < 0.0001). Rural victims were over seven times more likely to die before arrival (relative risk = 7.4, 95% confidence interval 2.4-22.8) if the emergency medical services' response time was more than 30 minutes. CONCLUSIONS: Response and transport times among professional, advanced life-support-trained paramedics responding to major trauma incidents are longer in rural areas, compared with urban areas.

Hospital services for rural children in Washington State.

OBJECTIVE: To examine the current delivery of inpatient hospital services to a statewide population of rural children, define the types of pediatric conditions currently treated in rural hospitals or transferred to urban centers, and explore the role of rural pediatricians and family practitioners in the care of children in rural hospitals. DESIGN: Retrospective review of statewide hospital discharge data. SUBJECTS: All patients younger than 18 years of age with nonsurgical diagnoses discharged from both urban and rural civilian hospitals in Washington State during 1989 and 1990. RESULTS: Of 69690 pediatric hospital discharges during the study period, 16% were rural residents and 10% were from rural hospitals. Rural hospitals cared for 59% of hospitalized rural children. Marked differences were found between urban and rural hospitals in the diagnoses treated; more than two-thirds of all discharges for chemotherapy, psychiatric disorders, and neonates with multiple major problems were from urban hospitals; but the majority of the discharges for gastrointestinal diagnoses, respiratory conditions, or minor problems in the neonatal period were from rural hospitals. Rural hospitals with staff pediatricians had higher annual pediatric discharges, total charges, lengths of stay, and case mix with a higher proportion of neonates with complications, compared to hospitals without pediatricians. However, there was no evidence that these hospitals served as local referral centers for rural pediatric inpatients; the proportion of patients from outside the local hospital catchment areas was similar for rural hospitals with staff pediatricians and for those without. In rural hospitals, pediatricians and family practitioners were listed as the attending physician for 37% and 49% of discharges, respectively. The average rural pediatrician cared for five times as many inpatients as a rural family practitioner. Pediatricians cared for significantly more neonates with birth weights of less than 2500 grams, but otherwise had a similar case mix among inpatient discharges as rural family practitioners. CONCLUSIONS: Most rural children in Washington who require hospitalization for common problems receive their care in local rural hospitals staffed with pediatricians and family practitioners, although those with illnesses requiring a high level of specialty care are predominantly cared for in urban centers. Rural pediatricians make a substantial contribution to the care of rural children, especially in the area of neonatal care, although their presence in rural hospitals does not in itself create local referral centers. Inpatient volumes are higher for pediatricians, but their case mix is similar to that of rural family practitioners, except in the area of neonatology. These data support the recommendations that family practitioners contemplating rural practice receive training in general inpatient pediatrics (regardless of whether they are going to a site with pediatricians) and that pediatricians in rural practice be trained for a high volume of inpatient cases, including problems of low birth weight infants. Because systems of hospital care for rural children depend on regionalized programs, clinical and educational linkages between urban centers and rural providers should be developed and supported.

The association between the purchase of a handgun and homicide or suicide.

OBJECTIVES: The purpose of this study was to determine whether purchase of a handgun from a licensed dealer is associated with the risk of homicide or suicide and whether any association varies in relation to time since purchase. METHODS: A case-control study was done among the members of a large health maintenance organization. Case subjects were the 353 suicide victims and 117 homicide victims among the members from 1980 through 1992. Five control subjects were matched to each case subject on age, sex, and zip code of residence. Handgun purchase information was obtained from the Department of Licensing. RESULTS: The adjusted relative risk of suicide was 1.9 (95% confidence interval [CI] = 1.4, 2.5) for persons with a history of family handgun purchase from a registered dealer. The adjusted relative risk for homicide, given a history of family handgun purchase, was 2.2 (95% CI = 1.3, 3.7). For both suicide and homicide, the elevated relative risks persisted for more than 5 years after the purchase. CONCLUSIONS: Legal purchase of a handgun appears to be associated with a long-lasting increased risk of violent death.

Safe storage of handguns. What do the police recommend?

OBJECTIVE: To ascertain the specific suggestions that local police departments in the United States give to parents who ask for advice about methods to safely store handguns. METHODS: A cross-sectional, semistructured telephone survey was administered to a sample of 102 police departments in the United States in cities with populations of 10,000 or more, selected within blocks of cities of similar population size. An investigator, posing as a parent of 3-year-old and 10-year-old children, called departments seeking specific advice on how to safely store a handgun acquired for protection. RESULTS: Usable responses were generated for 93 (91%) of the departments sampled. Only 3 departments (3.2%) refused to give advice over the telephone. The most commonly suggested storage methods were trigger locks (55 departments [59%]), portable lockboxes for handguns (48 [52%]), and the separation of guns from ammunition (30 [32%]). Seven percent of departments suggested removing the gun from the household. Over half of those suggesting trigger locks and lockboxes considered these devices safe (35 [64%] for trigger locks and 27 [56%] for lockboxes) and yet rapidly accessible to an adult (36 [65%] for trigger locks and 36 [75%] for lockboxes). Responding police officers most commonly reported using the following storage methods at home: no storage method (31 [38%]), portable lockboxes (23 [28%]), out-of-reach location (11 [13%]), separation of gun and ammunition (10 [12%]), and trigger locks (5 [6%]). CONCLUSIONS: Trigger locks are frequently recommended but infrequently used by police themselves at home. Portable lockboxes are frequently recommended as well as used by police.

Health care utilization as a marker for suicidal behavior on an American Indian Reservation.

OBJECTIVE: Overall suicide mortality rates are higher among American Indians than in the general population and are particularly high among Indians residing in the upper Midwest. The identification, during encounters with health care providers, of individuals at high risk of suicide is a potential intervention strategy. The purpose of this study was to examine whether increased health care utilization and symptom patterns were associated with suicide and suicide attempts among American Indian patients in an Indian Health Service facility. DESIGN: A case-control study design was used. SETTING/PATIENTS: Cases of completed suicides over a 6-year period and cases of suicide attempts over a 15-month period were identified on a Plains Indian Reservation. The pattern of utilization of health services by these subjects prior to their suicide or attempt was compared with that of control subjects matched for age and gender. MAIN RESULTS: Only 24% of subjects who died of suicide used the reservation clinic or hospital for services in the 6 months prior to their suicide, compared with 54% of controls (odds ratio [OR] 0.28; 95% confidence interval [CI], 0.09, 0.87). The patterns of symptom complaints and diagnoses for these visits did not differ significantly between case and control subjects. Case subjects who attempted suicide were more likely to be seen during the 6 months prior to their attempt than control subjects (57% vs 40%, OR 1.72; 95% CI 0.75, 3.93). Persons who attempted suicide were more likely to have documentation of psychological and interpersonal problems than were control subjects. Only 14% of subjects completing suicide had a previous history of suicide attempts. CONCLUSIONS: In this region, American Indians who committed suicide were less likely to use clinical services provided by the Indian Health Service prior to their death. However, there was a relatively strong association between suicide attempts and the prior use of health services, particularly the use of mental health services. In this American Indian population, clinic-based methods for early detection and intervention to prevent imminent suicide would reach fewer than one fourth of suicide victims. Further research is needed to identify the usefulness of community outreach efforts to identify and intervene among individuals at high risk of death by suicide.

The validity of police assessment of driver intoxication in motor vehicle crashes leading to hospitalization.

We evaluated the accuracy of the field sobriety assessment of police officers following a motor vehicle crash. Using linked data from a statewide traffic crash database and the trauma center registry, the results of a field sobriety evaluation for each driver were compared with a blood alcohol concentration (BAC) drawn in the emergency department. BAC values served as the "gold standard" in which drivers with values over 0.1 mg/dl were classified as intoxicated. The subjects were drivers over age 15 years who were admitted or died at Level I trauma center as a results of motor vehicle crash injuries during 1986-1993. A total of 1336 subjects had both a recorded BAC and a police sobriety assessment. Seventy percent of subjects were male and 79% under the age of 35 years. Overall, 40% of all subjects were judged by police to have been impaired, based on the scene sobriety assessment. Among all drivers, the field assessment had a sensitivity of 91%, a specificity of 90% and a predictive value positive of 85%. After excluding the 419 drivers which had breath testing as part of their assessment, the field assessment had a sensitivity of 74% and a specificity of 97%. The sensitivity of the field assessment did not vary appreciably by gender but was lower among older drivers, and higher among severely injured drivers and those involved in weekend and nighttime crashes. Police officers in this sample appear to recognize drunk driving with a high degree of accuracy when investigating crashes in which the driver is transported to a trauma center.

Physician experience with pediatric inpatient care in Washington State.

OBJECTIVE: To determine the frequency with which pediatricians and family physicians in Washington State serve as attending physicians for pediatric inpatients. DESIGN: Retrospective review of statewide hospital discharge data. SUBJECTS: Attending physicians for all patients younger than 18 years of age with nonsurgical diagnoses discharged from civilian hospitals in Washington State during 1989 and 1990. RESULTS: Using medical rosters, the self-identified specialty of the attending physician was determined for 93% (n = 181,581) of discharges. Pediatricians and family physicians were listed as attending for 61% and 28%, respectively, of all eligible patients. Statewide, 97% (n = 555) of all pediatricians and 86% (n = 939) of all family physicians served as attending physicians for at least one inpatient, including healthy newborns, during the 2-year study period. The median annual number of discharges per physician was 78 for pediatricians and 14.5 for family physicians. Excluding healthy newborns, the median annual number of discharges was 25 for pediatricians and 3 for family physicians. Five percent of the physician attending group provided inpatient care for 50% of all children hospitalized with diagnoses other than healthy newborn; 50% of attending physicians cared for 95% of the patients. In rural hospitals, where family physicians served as attending physicians for 44% of pediatric inpatients, children were 3.3 times more likely to receive their care from family physicians than those hospitalized in urban centers. CONCLUSIONS: Most pediatricians and family physicians serve as inpatient attending physicians for hospitalized children only infrequently. These findings question whether the emphasis on inpatient care in many pediatric and family medicine training programs remains an appropriate goal.

Epidural hemorrhage: is it abuse?

OBJECTIVE: To determine whether children presenting with epidural hemorrhage (EDH) are as likely to have been abused as are children presenting with subdural hemorrhage (SDH). DESIGN: Retrospective chart review. SETTING: Level I regional trauma center and a regional children's hospital. PATIENTS: All children at both institutions 3 years old or younger with a diagnosis of EDH or SDH identified by a search of the computerized trauma registry and hospital medical records from 1985 through 1991. MEASUREMENT AND RESULTS: Complete records were found for 93 of 94 eligible subjects. The diagnosis of accidental or inflicted injury was ascertained from the patient's hospital medical record or the records of Child Protective Services. Of all subjects (n = 93), 52% (48/93) were male and the median age was 15 months. Abuse was diagnosed in 47% (28/59) of children with SDH and 6% (2/34) of those with EDH. Other significant injuries were found in 47% of children with SDH and 18% of children with EDH. There was no statistically significant difference between the two groups with respect to the likelihood of identifying a skull fracture, the need for surgical evacuation of the hemorrhage, or mortality. CONCLUSIONS: Our data are consistent with current biomechanical concepts of intracranial injury. EDHs results from brief linear contact forces that commonly occur in unintentional falls. SDHs are caused by global high-energy rotational acceleration/deceleration forces that are commonly generated in episodes of abuse. Compared with SDH, EDH rarely results from abuse.

Prevention of traumatic deaths to children in the United States: how far have we come and where do we need to go?

OBJECTIVE: To describe the changes in injury mortality from 1978 to 1991 and determine the number of preventable deaths with currently available intervention strategies. METHODS: Comparison of injury mortality data for children and adolescents 0 to 19 years in 1978 and 1991. Review of the literature to determine the effectiveness of currently available prevention strategies and application of these to deaths in 1991. RESULTS: The injury death rate declined by 26% over the 14-year period. Death rates of unintentional injuries decreased by 39%, with declines in all categories of unintentional injuries. Homicides increased by 67% and suicides by 17%; nearly all of this increase was in deaths from firearms. If currently available prevention strategies were fully used, 6640 deaths could have been prevented, a further 31% decrease. CONCLUSIONS: Although great studies have been made in preventing deaths from trauma, the application of currently available prevention strategies could save a large number of additional lives. However, the increasing problem of intentional injury will partly counterbalance the success in unintentional injury control.

Prevalence of corporal punishment among students in Washington State schools.

OBJECTIVES: To determine the prevalence of corporal punishment in Washington State and the factors associated with its use in Washington elementary and secondary schools. DESIGN: Cross-sectional mail survey performed during the summer of 1992. SETTING: All elementary and secondary schools in the state of Washington. RESULTS: One thousand eighteen schools (47%) responded to the survey, of which 80% were publicly funded and 63% were located in urban areas. The study sample closely resembled the profile of all schools in the state. Almost 11% of participating schools permitted corporal punishment at the time of the survey and 3.2% reported its actual use during the 1991-1992 school year, resulting in an estimated prevalence of 7.2 incidents per 1000 students per year. Sixteen percent of corporal punishment actions occurred in schools not permitting its use. Ninety percent of public schools relied on district policy regarding corporal punishment. School characteristics associated with the use of corporal punishment included rural location (crude odds ratio, 2.2; 95% confidence interval, 1.5 to 3.4), enrollment of less than 500 students (crude odds ratio, 1.7; 95% confidence interval, 1.1 to 2.7), and kindergarten to eighth-grade or kindergarten to 12th-grade enrollment (crude odds ratio, 2.5; 95% confidence interval, 1.6 to 3.9). CONCLUSIONS: The lack of a statewide ban on school corporal punishment at the time of this survey was associated with the continued use of corporal punishment against children in districts that continued to permit it. School policies against corporal punishment were associated with much lower prevalence. Continued efforts are needed to enact and enforce laws in the remaining states that have not yet banned corporal punishment.
