Child and adolescent suicide deaths in New Mexico, 1990-1994.
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.

Male discomfort during the digital rectal examination: does examiner gender make a difference?
To determine if examiner gender affects men's perceived pain and embarrassment during an emergency department (ED) digital rectal examination, we prospectively studied male ED patients undergoing rectal examination. Each subject's perceived pain and embarrassment was gauged using 100 mm visual analog scales. Age, complaint, and examiner gender and training level were recorded. Two-tailed Mann-Whitney or Kruskal-Wallis tests examined significant differences among group mean pain and embarrassment scores. Of 126 subjects, 60 had female and 66 had male examiners. Mean pain scores were similar for patients of female (36.5 mm) and male (37.4 mm) examiners (95% CI -9.8 to 11.5, P = .73). Mean embarrassment scores were similar for female (36.6 mm) and for male (32.9 mm) examiners (95% CI -7.9 to 15.3, P = .67). Younger male patients experienced more pain and embarrassment (P < .027). Examiner training level and prostatic examination did not affect the score.

Disturbing trends: the epidemiology of pediatric emergency medical services use.
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.

Time series forecasts of ambulance run volume.
To test the hypothesis that time series analysis can provide accurate predictions of future ambulance service run volume, a prospective stochastic time series modeling study was conducted at a community-based regional ambulance service. For all requests for ambulance transport during two sequential years, the time and date, total run time, and acuity code of the run were recorded in a computer database. Time series variables were formed for ambulance service runs per hour, total run time, and acuity. Prediction models were developed from one complete year's data (1994) and included four model types: raw observations, moving average, means with moving average smoothing, and autoregressive integrated moving average. Forecasts from each model were tested against observations from the first 24 weeks of the subsequent year (1995). Each model's adequacy was tested on residuals by autocorrelation functions, integrated periodograms, linear regression, and differences among the variances. A total of 68,433 patients were seen in 1994 and 32,783 in the first 24 weeks of 1995. Large periodic variations in run volume with time of day were found (P < .001). A model based on arithmetic means of each hour of the week with 3-point moving average smoothing yielded the most accurate forecasts and explained 54.3% of the variation observed in the 1995 test series (P < .001). Time series analysis can provide powerful, accurate short-range forecasts of future ambulance service run volume. Simpler, less expensive models performed best in this study.

Farm-related injury mortality in New Mexico, 1980-91.
To compare the epidemiology of farm with non-farm occupational injury deaths, we reviewed state medical examiner data for all occupational injury deaths in New Mexico from 1980 to 1991. We identified 53 farm-related injury deaths for a rate of 21.3 per 100,000 worker-years. Farm workers were four times more likely than non-farm workers to die from occupational injury. American Indians had the highest farm injury death rate. Farm decedents were older than non-farm decedents (t498 = 6.29, p < 0.0001). Half of the farm decedents were 50 years of age or older; one-third were 60 years of age or older. Crush injuries accounted for half of all farm injury deaths including 18 of 23 motor vehicle deaths, half of these involving a tractor rollover. One in six farm injury deaths were from electrocution: one in five involved alcohol. Our study indicates that New Mexico has high farm-related injury mortality related to tractor use, alcohol intoxication, farm animals, and exposure to electricity. American Indians and older males are especially susceptible to these factors.

Does a physician visual assessment change triage?
A prospective comparative trial was conducted to determine the effect of a physician's visual assessment of emergency patients on triage categorization and ability at triage to predict admission. The setting was a university, county, referral center and residency training site. Participants were a consecutive sample of emergency department patients presenting between the times of 0700 and 2300 hours for 5 weeks. All patients were assigned a triage category by an emergency nurse (RN) who saw the patient and by an emergency physician (EP) who had the option of performing a visual assessment. Triage categorization was compared for interobserver agreement (Kappa [kappa] statistic) and by ability to predict admission (MacNemar's test). A total of 3,949 patients was entered. The patients that physicians visually assessed were triaged by nurses as more ill (P < .001). For triage categories visualized by the EP compared with RN categorization, interobserver agreement was 59.8%, kappa = .21. For triage categories not visualized by EP compared with RN categorization, interobserver agreement was 67.9%, kappa = .45 (P < .001). Sensitivity of EPs to predict admission is as follows: all RN triage, 41.3; not seen by EP, 54.9; seen by EP, 69.3. Specificity is as follows: all RN triage, 93.7; not seen by EP, 88.5, seen by EP, 83.9. When physician visual assessment was done, agreement between physicians and nurses decreased by more than half. Physicians who included visual assessment in patient triage were less likely to agree with RN categorization. A visual assessment by the physician improved the sensitivity for predicting admission with an only small cost in specificity.

Women's perception of pain and distress during intravenous catheterization and urethral mini-catheterization.
A study was done to prospectively compare the pain and distress of urethral mini-catheterization (MC) with the pain and distress of intravenous (IV) catheterization in women. Ten-centimeter visual analog scales were used on which the left end represented "no pain" or "no distress" and the right "the worst pain imaginable" or "extreme distress." Distress was defined to include embarrassment, anxiety, or fear. A convenience sample of 40 adult women who presented to a university emergency department and were undergoing both procedures as part of their management appraised pain and distress after IV placement and urethral MC. The mean IV pain score was 4.2 cm, whereas the mean MC score was only 2.6 cm (P = .02). The IV and MC distress score means were similar (2.3 v 2.6 cm, P = .55). These results suggest that patients perceive urethral MC as less painful than IV placement. The distress scores of these two procedures did not differ and were low in both instances.

Triage: limitations in predicting need for emergent care and hospital admission.
STUDY OBJECTIVE: Little is known about the accuracy and reliability of current triage methods. We examined agreement among observers with regard to the need for ED care and the ability to predict at triage the need for admission to the hospital and compared these findings with admission rates after medical evaluation and management. METHODS: We used a crossover design in which each subject was subjected to nurse or computer-guided triage first, the other type of triage second, and physician triage last. Our null hypothesis: Triage methods will yield the same results. Our patients were a consecutive sample of patients at the ED of a university-affiliated county referral center. Critically ill patients were excluded. Triage categorization was examined for interobserver agreement (kappa-statistic) and prediction of admission (sensitivity, specificity, and predictive values). RESULTS: Of the 5,106 patients enrolled in the study, 289 (6.2%) were admitted. With regard to the agreement of triage categorizations, we found kappa-values of .452 and .185, respectively, for physician triage compared with nurse (SE +/- .012) and computer triage (SE +/- .012)(P = .001 for the difference between the kappa values). Sensitivity and specificity in predicting admission were 41.3 and 93.8, respectively, for nurses, 61.6 and 87.1, respectively, for physicians; and 68.2 and 73.6, respectively, for computer-aided triage. CONCLUSION: We found great variability among physicians, nurses, and a computer program with regard to triage decisions. Comparison of the three groups' triage decisions with actual data after medical evaluation and management showed that none of the three performed well in predicting which patients required admission. Until triage methods are standardized and validated, triage decisions should not be used to determine the timeliness of access to emergency care.

Research directions in emergency medicine.
The goal of emergency medicine is to improve health while preventing and treating disease and illness in patients seeking emergency medical care. Improvements in emergency medical care and the delivery of this care can be achieved through credible and meaningful research efforts. Improved delivery of emergency medical care through research requires careful planning and the wise use of limited resources. To achieve this goal, emergency medicine must provide appropriate training of young investigators and attract support for their work. Promotion of multidisciplinary research teams will help the specialty fulfill its goals. The result will be the improvement of emergency medical care which will benefit not only the patients emergency physicians serve but also, ultimately, the nation's health.

The relationship between National Resident Match Program rank and perceived performance in an emergency medicine residency.
A nonconcurrent prospective cohort study was conducted to evaluate if National Resident Matching Program (NRMP) rank developed using multivariate regression followed by consensus group activity is associated with perceived general performance during emergency medicine residency. All residents graduating from a university hospital-based residency program between 1990 to 1993 were ranked by university faculty, private attendings, charge nurses, and a clerk. Each evaluator was asked to order (from the strongest to the weakest) a deck of cards that contained only each graduate's name and picture. NRMP ranks were scaled to adjust for differences in each year's match list length. Evaluators were unaware of the graduates NRMP ranks. Agreement among raters was analyzed using Kendall's coefficient of concordance. Perceived ranks were compared with actual NRMP ranks using the Spearman correlation procedure. Twenty graduates were evaluated by eight different individuals, yielding 160 pairs of ranks. There was moderately strong agreement among evaluators about the relative strength of the 20 residents (W = 0.67, P < .001). The association of perceived rank with NRMP rank was much greater than that expected by chance (r(s) = .35, P < .0001). Applicants with better NRMP ranks were perceived as stronger residents, which supports the strategy of using formal statistical modelling followed by consensus group activity as a method of generating NRMP rank lists.
