SummaryObjective: To compare results from high probability matched sets versus imputed matched sets across differing levels of linkage information.Methods: A series of linkages with varying amounts of available information were performed on two simulated datasets derived from multiyear motor vehicle crash (MVC) and hospital databases, where true matches were known. Distributions of high probability and imputed matched sets were compared against the true match population for occupant age, MVC county, and MVC hour. Regression models were fit to simulated log hospital charges and hospitalization status.Results: High probability and imputed matched sets were not significantly different from occupant age, MVC county, and MVC hour in high information settings (p > 0.999). In low information settings, high probability matched sets were significantly different from occupant age and MVC county (p < 0.002), but imputed matched sets were not (p > 0.493). High information settings saw no significant differences in inference of simulated log hospital charges and hospitalization status between the two methods. High probability and imputed matched sets were significantly different from the outcomes in low information settings; however, imputed matched sets were more robust.Conclusions: The level of information available to a linkage is an important con -sideration. High probability matched sets are suitable for high to moderate information settings and for situations involving case- specific analysis. Conversely, imputed matched sets are preferable for low information settings when conducting population-based analyses.
Objective: To classify poisoning deaths of undetermined intent as either suicide or unintentional and to estimate the extent of underreported poisoning suicides. Methods: Based on 2002 statewide death certificate and medical examiner data in Utah, the authors randomly selected one half of undetermined and unintentional poisoning deaths for data abstraction and included all suicides. Bivariate analyses assessed differences in demographics, death characteristics, forensic toxicology results, mental health history, and other potentially contributing factors. Classification and regression tree (CART) analysis used information from unintentional and suicide poisoning deaths to create a classification tree that was applied to undetermined poisoning deaths. Results: The authors analyzed 41 unintentional, 87 suicide, and 84 undetermined poisonings. Undetermined and unintentional decedents were similar in the presence of opiates, physical health problems, and drug abuse. Although none of the undetermined decedents left a suicide note, previous attempt or intent to commit suicide was reported for 11 (13%) of these cases. CART analysis identified suicidal behavior, drug abuse, physical health problems, depressed mood, and age as discriminating between suicide and unintentional poisoning. It is estimated that suicide rates related to poisoning are underreported by approximately 30% and overall suicide rates by 10%. Unintentional poisoning death rates were underreported by 61%. Conclusions: This study suggests that manner of death determination relies on circumstance dependent variables that may not be consistently captured by medical examiners. Underreporting of suicide rates has important implications in policy development, research funding, and evaluation of prevention programs.
BACKGROUND:This study examines the potential for misclassifying injury-related deaths reported in Vital Statistics and assesses the rate of postdischarge death among injured patients released from hospital, emergency department (ED), and emergency medical services (EMS) care. METHODS:Statewide death certificate, inpatient, ED, and EMS databases for 1996 through 1997 were probabilistically linked and information in each database compared. RESULTS:One thousand two hundred ninety-four injured inpatients or ED patients were matched with a death certificate record that listed an injury (56.3%) or illness (43.7%) as the primary cause of death. Injured decedents with an illness-coded cause of death were older (p < 0.001), with causes of death indicative of chronic medical conditions. Few deaths occurred within 30 days of inpatient discharge (6%); however, 38% and 9% of deaths in ED and EMS databases occurred after discharge from health care, respectively. Many deaths among EMS and ED patients occur in subsequent phases of care. CONCLUSION:Estimates of injury mortality substantially increase when using multiple independent databases.
Objective: Measure changes in the prevalence of behavioral factors including police-reported fatigue and alcohol intoxication, as well as self-reported seatbelt use, and assess their effect on hospitalization or death after a motor vehicle crash. Methods: Probabilistic linkage was used to match drivers in motor vehicle crashes with hospital discharge records for the years 1992-1997. Frequencies of specific behavioral factors were evaluated using the Cochran-Armitage test for trend. Odds ratios and corresponding 95% confidence intervals were calculated using generalized estimating equations (GEEs) with crash and driver characteristics as independent variables and hospitalization or death as the dependent variable. Results: The analysis database consisted of 450,286 crash driver records, which linked to 4219 (0.9%) hospitalizations or deaths. There was an increasing trend for self-reported seatbelt use among crash-involved drivers from 80.5% in 1992 to 89.3% in 1997 (P < 0.001). Police-reported alcohol intoxication among crash-involved drivers showed a decreasing trend from 2.4% in 1992 to 1.5% in 1997 (P < 0.001). There was no trend for police-reported fatigue-related crashes. Odds ratios of hospitalization or death for seatbelt use, alcohol involvement, and fatigue were significant and did not fluctuate considerably between 1992 and 1997. Seatbelt use offered a protective effect from hospitalization or death, while alcohol intoxication and fatigue contributed to increased likelihood of hospitalization or death. Conclusions: These results suggest that while some improvement has been made in decreasing seatbelt non-use and driver alcohol intoxication among crash-involved drivers, no improvement has been made in reducing fatigue-related crashes.

The objective of this study was to determine the annual incidence of fatal motor vehicle crashes involving street racing and to describe the characteristics of these crashes compared to other fatal crashes in the United States. The National Highway Traffic Safety Administration Fatality Analysis Reporting System data for 1998–2001 were used for the analyses. There were 149 568 fatal crashes and 315 (0.21%) involved street racing and 399 fatalities occurred in these crashes. In contrast to other fatal crashes, street racing fatal crashes were more likely to occur on urban roadways and were nearly six times more likely to occur at travel speeds ≥65 mph. Compared with other drivers involved in fatal crashes, street racers were more likely to be teenagers, male, and have previous crashes and driving violations. Street racing involves risky driving behaviors and warrants further attention.
OBJECTIVE:To assess the effect of maternal involvement in motor vehicle crashes on the likelihood of adverse pregnancy outcomes and to estimate the effect of seatbelt use in reducing the occurrence of those outcomes.METHODS:Statewide motor vehicle crash, birth, and fetal death records from 1992 to 1999 were probabilistically linked. Logistic regression was used to compare the likelihood of adverse birth and fetal outcomes including low birth weight, prematurity, placental abruption, fetal distress, excessive bleeding, fetal death, and other complications among pregnant women in crashes and those not in crashes.RESULTS:Of 322,704 single live resident births, 8938 mothers (2.8%) experienced a crash during pregnancy. Pregnant women using seatbelts were not significantly more at risk for adverse fetal outcomes than pregnant women not in crashes. However, pregnant women who did not wear seatbelts during a crash were 1.3 times more likely to have a low birth weight infant than pregnant women not in a crash (95% confidence interval [CI] 1.0, 1.6) and twice as likely to experience excessive maternal bleeding than belted pregnant women in a crash (95% CI 1.0, 4.2). Forty-five of 2645 fetal deaths were linked to a motor vehicle crash, with unbelted pregnant women 2.8 times more likely to experience a fetal death than belted pregnant women in crashes (95% CI 1.4, 5.6).CONCLUSION:Pregnant women should be counseled to wear seatbelts throughout pregnancy and reduce crash risk.
This study investigates relationships between file sizes, amounts of information contained in commonly used record linkage variables, and the amount of information needed for a successful probabilistic linkage project. We present an equation predicting the amount of information needed for a successful linkage project. Match weights for variables commonly used in record linkage are measured using artificially created databases. Linkage algorithms were successful when the sum of minimum weights for variables used in a linkage exceeded the predicted cutoff. Linkage results were acceptable when this sum was near the predicted cutoff. This technique enables researchers to determine if enough information exists to perform a successful probabilistic linkage.
This article explores the methods by which practitioners have traditionally approached international conflicts. Approaches focusing on the resources or the interests of the parties can be appropriate methods of resolution in conflicts where resources and interests are the only issues at stake. However, conflicts raging today often contain issues of identity. These identity-based, ethnopolitical conflicts are often resistant to traditional resource- and interest-based resolution methods. This article suggests a different approach, one that emphasizes needs, and in particular identities, of conflicting parties. We suggest that such a focus is essential in working towards resolution in many of the deeply rooted conflicts in today's world. We explore the ARIA model of conflict engagement as a mechanism for a systematic approach to interactive conflict resolution that specifically deals with the complex issues of identity. We also offer a preliminary evaluation of interactive conflict resolution as a general approach in varied international conflict situations. The question of interactive conflict resolution effectiveness is explored using Licklider's data for civil war termination and Bercovitch's data for international conflict mediation.
OBJECTIVE:To describe the epidemiology of snowmobile injuries in Utah.METHODS:Analysis of probabilistically linked statewide emergency department (ED), hospital admission, and death certificate data for 1996 and 1997.RESULTS:There were 625 cases of snowmobile-related injuries. The majority (83%) were evaluated in the ED only. Median ED patient age was 29 years (range 3-74 years), and 66% were male. The leading diagnoses were open wounds to the head (7.8%), back strains (5.4%), and contusions of the trunk and lower extremities (5.2% and 5.0%, respectively). An Injury Severity Score (ISS) of > or = 4 (range 1-75) was found in 37% of the ED patients. The median charge was $373 per patient, with two-year cumulative charges of $266,283. One hundred seven patients required inpatient hospital care. Median inpatient age was 32 years (range 4-92 years), and 60% were male. Leading inpatient diagnoses were fracture of the vertebral column (9.3%), lower extremity fracture (9.3%), upper extremity fracture (6.5%), and pelvis fracture (3.7%). An ISS of > or = 4 (range 1-38) was found in 70% of the hospitalized patients. Average length of stay was 3 days, with a range of 1 to 68 days. Median inpatient charge was $6,003 per patient, with two-year cumulative charges of $1,333,218. Ten inpatients required transfer for rehabilitation or skilled nursing care. There were a total of six fatalities, three of which occurred in the ED, one in the inpatient population, and two identified from the death certificate database.CONCLUSIONS:By combining ED, inpatient, and death certificate data sets, probabilistic linkage provides a comprehensive description of snowmobile-related injuries and a baseline evaluation of morbidity, mortality, and financial burden.
The purpose of our study was to evaluate the impact of shoulder belt use on motor vehicle crash ejection, morbidity and mortality. We analyzed motor vehicle crash records linked to hospital inpatient data for front seat occupants of passenger cars in Utah between 1994 and 1996 (n = 103,035). Stochastic simulations were used to adjust for possible seatbelt misclassification. There were 276 (0.3%) occupants coded as using only a shoulder belt. The adjusted odds of ejection for shoulder only belted occupants was higher compared to lap-shoulder belted (odds ratio (OR) = 18.9; 95% confidence interval (CI) = 15.1, 25.1) and lap only belted occupants (OR = 4.3; 95% Cl = 2.9, 7.7). There was no difference in the odds of ejection for an occupant using a shoulder belt only and an occupant using no seatbelt (OR = 1.1; 95% CI = 1.0, 1.3). Occupants using a shoulder belt only were more likely to sustain a fatal or hospitalizing injury than lap-shoulder belted (OR = 2.3; 95% Cl = 1.9, 3.0), and lap only belted occupants (OR = 1.8; 95% CI = 1.3, 2.7), while controlling for other covariates. Occupants using only a shoulder belt had the same odds of a fatal or hospitalizing injury as unbelted occupants (OR = 1.1; 95% Cl = 0.9, 1.4). Average hospital inpatient length of stay, charges and injury severity scores were similar for all restraint types. These results stress the need for the use of a lap belt in conjunction with the shoulder belt.
To assess the efficacy of occupant protection systems, the authors measured the mortality reduction associated with air bag deployment and seat belt use for drivers involved in head-on passenger car collisions in the United States. They used a matched case-control design of all head-on collisions involving two passenger cars reported to the Fatality Analysis Reporting System in 1992-1997, and driver mortality differences between the paired crash vehicles for air bag deployment and seat belt use were measured with matched-pair odds ratios. Conditional logistic regression was used to adjust for multiple effects. There were 9,859 head-on collisions involving 19,718 passenger cars and drivers. Air bag deployment reduced mortality 63% (crude odds ratio (OR) = 0.37, 95% confidence interval (CI): 0.32, 0.42), while lap-shoulder belt use reduced mortality 72% (OR = 0.28, 95% CI: 0.25, 0.31). In a conditional logistic model that adjusted for vehicle (rollover, weight, age) and driver (age, sex) factors, air bags (OR = 0.71, 95% CI: 0.58, 0.87) and any combination of seat belts (OR = 0.25, 95% CI: 0.22, 0.29) were both associated with reduced mortality. Combined air bag and seat belt use reduced mortality by more than 80% (OR = 0.18, 95% CI: 0.13, 0.25). Thus, this study confirms the independent effect of air bags and seat belts in reducing mortality.
OBJECTIVE:To describe the epidemiology of school injuries resulting in emergency department (ED) visits, hospital admission, or death.METHODS:Utah statewide school injuries from 1992 to 1996 were probabilistically linked to statewide ED records (1996 only), inpatient hospital records (1992-1996), and death certificate records (1992-1996).RESULTS:There were 43,881 school injuries for the years 1992 through 1996. In 1996, 1,534 of 6,354 total school injuries (17.5%) resulted in ED evaluation. Between 1992 and 1996, 354 school injuries (0.8%) necessitated hospital admission. The overall rates of school injuries (per 1,000 students) of primary (kindergarten-grade 6) and secondary (grades 7-12) school students requiring ED evaluation were 3.29 and 3.28, respectively; for hospital admission, 0.165 and 0.139. Abbreviated Injury Scale-1990 (AIS-90) regions identified in ED patients were the upper extremity (39.2%), face (20.8%), and lower extremity (17.1%), while AIS regions among inpatients were lower extremity (29.1%), upper extremity (26.6%), and head (22.6%). There were a total of 1,123 hospital days, and total charges of $2.16 million. The ED charges totaled $545,000. Median length of hospital stay was 1 day, and median hospital charge was $3,080. There were four fatalities.CONCLUSIONS:This study emphasizes the significance of school injuries and the need for interventions to prevent these injuries
Objective. Injuries in the school environment are a serious public health problem. Injuries occurring within the school shop class are a part of this problem that has received little to no attention. The purpose of our study was to describe the epidemiology of shop class injuries in Utah public schools for the years 1992-1996.Methods. Utah statewide grades 7 through 12 school injury data for 1992-1996 were used. The data were generated from a standardized Student Injury Report form completed by school personnel immediately after the occurrence of an injury on school premises that: 1) caused loss of at least one half of a day of school; and/or 2) warranted medical attention and treatment. Shop injuries were defined as injuries that occurred in industrial art classes, vocational educational classes, or automotive classes. To determine the medical outcome and hospital charges associated with shop class injuries, we linked the Student Injury Report database to Utah statewide emergency department (ED) records (available for 1996 only), and to Utah statewide hospital inpatient discharge records (1992-1996).Results. During 1992-1996, 14 133 students in grades 7 through 12 were injured at school, of which 1008 (7.1%) were injured during a shop class. The majority (88.4%) of shop injuries involved equipment use. Equipment was misused in 37.9% and malfunctioned in 3.5% of the incidents. The leading injuries reported for shop equipment were lacerations (70.9%), burns (6.0%), and abrasions (4.6%), whereas the leading for nonequipment injuries were lacerations (45.4%), fractures (9.2%), and pain/tenderness (6.7%).In 1996, 167 students were injured in a shop class and 45 (26.9%) visited an ED as a result of the shop injury. Equipment was a factor in 88.9% of the shop injuries admitted to the ED. Table saws (15.0%), other saws (15.0%), and band saws (12.5%) were involved in nearly one half of the equipment injuries. Equipment was misused in 44.7% and malfunctioned in 10.5% of the incidents resulting in an ED visit. The majority (64.4%) of students sustained an open wound injury. The total ED charges were $16 571.For 1992-1996, 1008 students were injured in a shop class, 7 (.7%) required inpatient hospital care. Six of the students were injured using a table saw and 1 sustained injuries attributable to automotive cleaning fluid. Equipment was used improperly in 4 of the table saw injuries. Six of the students sustained hand injuries, with 3 suffering a traumatic amputation of a finger or thumb. The total inpatient charges were $26 747.Conclusion. School shop injuries have a great impact on students, their families, and schools because of the loss of productivity for the student and the financial impact. Many of the injuries are preventable. These findings stress the need for school administrators, teachers, and students to develop and improve safety policies and practices in school shop classes. In addition, the findings may provide useful information to pediatricians and enable them to better inform patients of risks in school shop classes.
Study objective: We sought to compare the characteristics and medical outcomes of motor vehicle crashes for drivers 70 years and older with those of drivers between the ages of 30 and 39 years.Methods: We probabilistically linked statewide motor vehicle crash and hospital discharge data between the years of 1992 and 1995 for the state of Utah. We calculated the odds of older drivers exhibiting certain motor vehicle crash characteristics compared with younger drivers. Adjusting for nighttime crash, high-speed crash, and seatbelt use, we calculated the odds of an older driver being killed or hospitalized compared with those of a younger driver.Results: During the study years, there were 14,466 drivers older than 69 years and 68.706 drivers between the ages of 30 and 39 years involved in motor vehicle crashes in Utah. Older drivers were less likely to have crashes involving drug or alcohol use (odds ratio [OR] 0.1; 95% confidence interval [CI] 0.1 to 0.2) and less likely to have crashes at high speed (OR 0.6; 95% Cl 0.6 to 0.7). Although older drivers were no more likely to have a crash involving a right-hand turn (OR 1.0; 95% Cl 0.9 to 1.1) than younger drivers, they were over twice as likely to have a crash involving a left-hand turn (OR 2.3; 95% Cl 2.2 to 2.5). Also, older drivers were more likely to be killed or hospitalized than younger drivers (OR, 3.5; P<.001). Among belted drivers, an older driver was nearly 7 times more likely to be killed or hospitalized than a younger driver (OR 6.9; 95% Cl 5.4 to 8.9).Conclusion: Older drivers do have distinctive motor vehicle crash patterns. Interventions must be taken to reduce the number of left-hand turn crashes involving older drivers. In addition, further research is needed to design, implement, and evaluate countermeasures that may enable older drivers to continue driving while keeping public safety in the forefront.
OBJECTIVE:To compare pediatric ambulance patients transported for chief complaints of suicide, assault, alcohol, and drug intoxication (SAAD) with pediatric patients transported for all other chief complaints.METHODS:An out-of-hospital database for the primary transporting service in an urban area was analyzed for patients 0-20 years of age from 1992 to 1995. Chief complaints by age, gender, and billing status were analyzed.RESULTS:There were 17,722 transports. The SAAD group comprised 14.9% of all transports (suicide attempt 1.6%, assault 5.9%, alcohol intoxication 3.2%, and drug abuse 4.2%). The proportion of transports due to SAAD increased with age: 0-11-year-olds (4.2%); 11-16-year-olds (17.5%); and 17-20-year-olds (20.3%) (p = 0.0001). Genders were equally represented in the overall group, while males comprised 52.6% of the SAAD transports (p = 0.032). In the SAAD group, the majority of transports for assaults (55.9%) and alcohol (58.8%) involved males, while females were the majority in transports for suicide (52.3%) and drug abuse (66%) (p = 0.0001). Reimbursement sources differed, with those in the SAAD group less likely to be reimbursed by private or public (Medicaid, government) insurance (p < 0.0001) compared with the overall group.CONCLUSIONS:A substantial proportion of pediatric emergency medical services transports are for high-risk conditions. This patient population differs from the overall group by age distribution and reimbursement source.

The suicide death rate in New Mexico is consistently higher than the national rate. Among adolescents, suicide is the third leading cause of death nationally, but in New Mexico it is the second leading cause of death. This study describes the pattern of adolescent suicide deaths in New Mexico. We conducted a retrospective review of all medical examiner autopsies for adolescent suicides (ages 20 years and younger) in New Mexico from 1990-1994. Records were reviewed for demographics and possible contributing factors such as depression, previous attempts, and alcohol and drug use. We identified 184 suicide deaths among children and adolescents ages 9-20 years for an overall rate of 12.9 per 100,000. Our rates for ages 5-9 years (0.2), 10-14 years (3.8), and 15-19 years (22.3) are over twice the U. S. rates. Suicide deaths resulted primarily from firearms (67%), hanging (16%), poisoning (6%), inhalation (4%), and other methods (7%). Method varied by ethnicity (p = .01) and gender (p = .03); males and non-Hispanic Whites were overrepresented among firearm deaths. Firearm ownership was known in 60 (48%) of the firearm deaths. Of these, 53% of the firearms belonged to a family member, 25% to the decedent, and 22% to a friend. Over one-third of decedents (41%) experienced mental disorders, primarily depressed mood and clinical depression. Previous suicide attempts were noted for 15% of the decedents. Some 50% of the decedents had alcohol or drugs present at the time of death; among American Indians/Alaska Natives, 74% had drugs or alcohol present (p = .003). Targeted interventions are needed to reduce adolescent suicide in New Mexico. We suggest raising awareness about acute and chronic contributing factors to suicide; training physicians to look for behavioral manifestations of depression; and involving physicians, teachers, and youth activity leaders in efforts to limit firearm accessibility, such as advising parents to remove firearms from their households.
OBJECTIVETo compare the initial emergency medical services (EMS) prehospital assessment of medical and traumatic cardiopulmonary arrest in the pediatric patient with that of the Office of the Medical Investigator (OMI) and assess differences and implications for EMS training and prevention.DESIGNRetrospective review of ambulance run forms with the OMI autopsy confirmations.SETTINGAn urban EMS system and the state Office of the Medical Investigator.PARTICIPANTSPatients 15 years of age or less who were treated by prehospital personnel from November 1, 1990, to October 31, 1991, for a medical or traumatic arrest.INTERVENTIONNone.MEASUREMENTS AND MAIN RESULTSAmbulance runs were reported for 2,586 pediatric patients. Of these, 42 (1.6%) had suffered arrests, with 32 (76%) medical arrests and ten (24%) traumatic arrests. Children 1 year of age or less accounted for 75% of the medical arrests, while children more than 1 year of age accounted for 80% of the traumatic arrests (p = 0.003). Overall mortality was 81%. When EMS prehospital assessments of medical and traumatic arrests were compared with autopsy reports, there was good agreement for sudden infant death syndrome (SIDS) (kappa = 0.70), but poor agreement for child abuse (kappa = 0.37).CONCLUSIONThe authors found good agreement between EMS prehospital assessments and autopsy diagnoses for identifying pediatric SIDS, but child abuse was not well identified prior to autopsy.
