Methodological issues in the surveillance of poisoning, illicit drug overdose, and heroin overdose deaths in new Mexico.

New Mexico leads the nation in poisoning mortality, which has increased during the 1990s in New Mexico and the United States. Most of this increase has been due to unintentional deaths from illicit drug overdoses. Medical examiner and/or vital statistics data have been used to track poisoning deaths. In this study, the authors linked medical examiner and vital statistics records on underlying cause of death, coded using the International Classification of Diseases, Ninth Revision, to assess the extent to which these data sources agreed with respect to poisoning deaths. The authors used multiple-cause files, which are files with several causes listed for each death, to further assess poisoning deaths involving more than one drug. Using vital statistics or medical examiner records, 94.7% of poisoning deaths were captured by each source alone. For unintentional illicit drug and heroin overdose deaths, each data source alone captured smaller percentages of deaths. Deaths coded as E858.8 (unintentional poisoning due to other drugs) require linkage with medical examiner or multiple-cause records, because this code identifies a significant percentage of illicit drug overdose deaths but obscures the specific drug(s) involved. Surveillance of poisoning death should include the use of medical examiner records and underlying- and multiple-cause vital statistics records.

Eimerians in harvest mice, Reithrodontomys spp., from Mexico, California and New Mexico, and phenotypic plasticity in oocysts of Eimeria arizonensis.

Between May 1979 and August 1991, 48.7% (57/117) of the harvest mice (Reithrodontomys spp.) examined from 10 localities in Mexico, California and New Mexico had coccidian oocysts in their feces. A total of 46.7% (49/105) of the Reithrodontomys megalotis examined were positive for coccidian oocysts; this included samples from five states in Mexico (47.1%, 8/17), three counties in California (66.7%, 4/6) and two counties in New Mexico (45.1%, 37/82); 66.7% (8/12) of the Reithrodontomys montanus from one county in New Mexico also were infected. Only two coccidian species, Eimeria arizonensis and Eimeria langebarteli, were found in these hosts. Oocysts of E. langebarteli were found only in R. megalotis: in all three infected mice from Madera County, California, in the only mouse from San Bernardino County, California, and in 63% (5/8) of the infected mice from four states in Mexico. Oocysts of E. arizonensis were found in R. megalotis in Mexico, California, and New Mexico and in R. montanus from New Mexico. Sporulated oocysts of E. langebarteli differed slightly from those in previously published reports by having wider oocysts and larger sporocysts. Sporulated oocysts of E. arizonensis were variable in size, with those recovered from R. montanus significantly larger in length and width and sporocyst width than those from R. megalotis. The structure of the oocyst residuum was polymorphic, both within and between host species, and within the same mouse; it could appear as one large globule, two globules, several to many smaller globules, or as a compact mass of many small granules. Oocysts with a variable residuum were larger than those with one globule in all oocyst/sporocyst dimensions.(ABSTRACT TRUNCATED AT 250 WORDS)

Community-oriented medical education: comparison of tracks in Mexico and New Mexico.

Most major innovations in medical education have occurred in a small number of new schools. Attempts to create change in traditional schools are far more complex. Relevant models for such change are few and there is an urgent need for institutions pioneering such changes to learn from each other's experiences. Two conventional medical schools described in this paper have attempted to create community-oriented institutional change by establishing experimental undergraduate curricular tracks. One is in a developing country, Mexico, the other in a technically developed country, the United States. These new tracks in medical education evolved independently of one another, yet they have many similarities and have experienced common problems. A formal exchange between the two schools has led to new insights in medical education and improvements to both programmes. Exchange agreements like the one reported here would be valuable for other medical schools in both developing and technically developed countries.

A survey of the expectations of New Mexico emergency physicians regarding the services of the New Mexico Poison and Drug Information Center.

OBJECTIVE: Physicians have been surveyed concerning their satisfaction with poison center services but have never been questioned regarding their expectations. This study was conducted to clarify the expectations of emergency physicians in New Mexico regarding the service of their regional poison center, the New Mexico Poison and Drug Information Center. DESIGN: Five New Mexico emergency department physicians were interviewed about their expectations when calling the New Mexico Poison and Drug Information Center. Their responses were combined with unique, additional expectations identified by the New Mexico Poison and Drug Information Center staff in order to develop a 62-item physician expectation mail survey instrument. Respondents were asked to rank the importance of each service expectation on a 5-point Likert scale (1 = not important, 5 = extremely important). RESULTS: A usable return rate of 60% was achieved (104 surveys). Fifty-eight (94%) expectations had a mean importance rating of > or = 3 (important). Ninety-four percent of the expectations included on the survey were being provided by the New Mexico Poison and Drug Information Center. CONCLUSION: Currently, there is a good fit between New Mexico emergency physician expectations and New Mexico Poison and Drug Information Center services provided. The instrument identified several areas where service was expected but not provided (Internet access to poison center, provision of industrial/occupational toxicology services, provision of tele-medicine capability) and where service was provided but not expected (drug dosing information). Surveying can be a valuable tool for clarifying expectations for poison center services.

History of midwifery in New Mexico: partnership between curandera-parteras and the New Mexico Department of Health.

Curandera-parteras (traditional Hispanic midwives) have been in northern New Mexico since before its statehood. In the 1930s, the New Mexico Department of Health began a valuable relationship with the curandera-parteras through the Midwife Consultant Program. This article describes the relationship between the curandera-parteras and the New Mexico Department of Health originating in the 1920s. The amenable and effective working relationship achieved between curandera-parteras and public health during this time period helped create the positive support for midwifery that is apparent in New Mexico today.

The New Mexico Mammography Project. Screening mammography performance in Albuquerque, New Mexico, 1991 to 1993.

BACKGROUND: This project was designed to collect and link population-based mammography and breast carcinoma data to assess the performance of community mammography screening. METHODS: Computerized data were collected from all radiology practices in Albuquerque, New Mexico. The data were linked by computer match to breast carcinomas in a statewide cancer registry. Analysis is based on 126,466 screening mammogram studies performed on 87,443 female residents of New Mexico between the ages of 35 and 84 by 5 radiology groups. Sensitivity, specificity, positive predictive value, and call back rates were calculated as indicators of the discriminative performance of mammography. Carcinoma size and stage distribution were analyzed as outcome measurements. RESULTS: The computer match linked 634 breast carcinomas to the 126,466 screening mammogram series. The community-wide sensitivity was 79.9%, and specificity was 90.5%. The predictive value of an abnormal screen was 4.3%, and that of a biopsy recommendation result was 16.9%. The call back rate was 11.4%. The median invasive breast carcinoma size was 15 mm, 20.3% of carcinomas were in situ, 18.3% were lymph node positive, and 68.1% were Stage 0 or Stage 1. CONCLUSIONS: Mass screening mammography as practiced in Albuquerque, New Mexico, is able to detect breast carcinomas at early, treatable stages. The stage distribution of carcinomas is similar to that seen in successful clinical trials. However, measures of mammography performance show lower sensitivity, more additional studies, and more biopsy recommendations in this community setting than have been reported by expert mammographers.

Assessing or predicting adoption of telehealth using the diffusion of innovations theory: a practical example from a rural program in New Mexico.

In New Mexico, a large rural state, it was anticipated that telehealth would bring significant value to health care delivery, improve local capacity for patient care, decrease the need for patient travel, diminish professional isolation, provide an avenue for enhanced professional education and information sharing, increase access to care, and ultimately improve health status. During the course of an evaluation of the University of New Mexico Center for Telehealth's rural telemedicine program, we used a grounded theory approach to assess barriers to the adoption of telemedicine and components of successful adoption. We then turned to the diffusion of innovations theory to better understand the dynamic interactions between the characteristics of telehealth and the social system in which it is applied. In doing so, we learned that the type of innovation decision involved in the adoption of telehealth appears to be particularly important in determining adoption. In this article we demonstrate that diffusion theory can be a useful framework for evaluating telehealth programs. We also suggest that the development of a predictive tool for prospective assessment would be useful, and could be applied when new telehealth programs are being planned.

Risk factors for victimization during the 1980 riot at the Penitentiary of New Mexico.

The New Mexico Penitentiary riot of February 2, 1980, resulted in death for 33 inmates at the hands of their fellow prisoners, and the hospitalization of 62 inmates for treatment of drug overdose or trauma. A case-control study of dead and hospitalized inmates was conducted to determine risk factors for victimization. Twelve (12.5%) of the 96 inmates housed in the protective custody unit were killed, compared with an overall penitentiary death rate of 2.9% (p = 0.0003). These 12 individuals were similar to the general inmate population with respect to age, race, years of education, crimes, time served, and prison rule infractions committed. In contrast, the 21 homicide victims housed in other areas were younger and had committed significantly greater numbers of rule infractions during incarceration. Prisoners hospitalized for drug overdose, but not those hospitalized for traumatic injuries, could be differentiated from the remaining prison population by increased convictions for homicide and higher prison infraction rates. Inmates in protective custody were targeted selectively for death; other subgroups of victims of violence appear to share characteristics often associated with perpetrators of violence.

Unintentional deaths from drug poisoning by urbanization of area--New Mexico, 1994-2003.

New Mexico experienced an increase in poisoning deaths during the 1990s and in 2002 was the state with the highest death rate (14.1 per 100,000 population) from unintentional poisoning, more than twice the national rate (6.1). The majority of these unintentional poisoning deaths were caused by ingestion of drugs, including illicit, prescription, and over-the-counter drugs. New Mexico is geographically diverse, with communities ranging from urban centers to sparsely populated counties. To examine the relationship between the types of drugs causing poisoning deaths and the levels of urbanization where the decedents resided, the New Mexico Department of Health analyzed data provided by the New Mexico Office of the Medical Investigator (OMI) for 1994-2003. All counties in New Mexico were classified as metropolitan or micropolitan statistical areas, or as nonstatistical areas, by using 2001-2002 population estimates in accordance with 2003 Office of Management and Budget (OMB) classifications. This report summarizes the results of that analysis, which indicated that deaths from illicit-drug poisoning were twice as likely to occur in metropolitan areas as nonmetropolitan areas (i.e., micropolitan and nonstatistical areas combined). However, deaths from prescription-drug poisoning were most likely to occur in micropolitan and nonstatistical areas. Investigation of drug-poisoning deaths by level of urbanization can be useful to public health programs to prevent unintentional drug-poisoning deaths.

Analysis of Texas & New Mexico Hospice Organization's new Code of Ethics.

Unique among professional codes of ethics is the Texas & New Mexico Hospice Organization's Code of Ethics. Where other codes concentrate only on principles-based ethics, this new code identifies five models of bioethics currently used in resolving ethical dilemmas. This report's primary purpose analyzes the code's four precepts in the context of (1) principles-based ethics, (2) casuistic-based ethics, (3) covenant-based ethics, (4) evidence-based ethics and narrative-based ethics. The second purpose is to present the practicality of these often esoteric concepts in the day-to-day work of palliative care providers. Indications are that this code of ethics, because of its broad scope, is more useful than other principles-based-only codes.

Child restraint law effects on motor vehicle accident fatalities and injuries: the New Mexico experience.

The New Mexico State Legislature passed a child restraint law applicable to children less than 5 years of age that became effective in June 1983. To evaluate the effectiveness of this law, we analyzed traffic accident data for New Mexico from January 1981 through September 1984. During this period, there were 20,972 children younger than 5 years of age in motor vehicle accidents. Restraint usage increased for this age group from a low of about 10% in 1981 to more than 40% in 1984 (P less than 10(-6)). Unrestrained children younger than 5 years of age were five times more likely to be killed and two times more likely to be injured than restrained children. Analysis of motor vehicle accident fatality and injury rates pre- and post-law revealed a 33% reduction in motor vehicle accident fatality rates and a 12.6% reduction in nonfatal injury rates for children younger than 5 years. We conclude that child restraint devices are effective in reducing motor vehicle accident fatalities and injuries in young children and the child restraint law has been effective in increasing child restraint usage and in reducing childhood death and injury in New Mexico.

Grassroots efforts pursue alcohol policy reform: refocusing upstream in New Mexico.

ORGANIZATION SETTING. The New Mexico Alcohol Issues Consortium (NMAIC) originated in January 1989 as a grassroots effort to focus on the reduction of driving-while-intoxicated (DWI) in New Mexico. It was the brainchild of three state health department officials and grew to include in its membership representatives from education, medicine, law enforcement, neighborhood associations, business, and local and state government. RATIONALE. New Mexico ranks at or near the top in several alcohol-related statistics, including motor vehicle fatalities, cirrhosis, and alcoholism. Furthermore, the 'alcohol environment' in New Mexico included the allowance for the purchase of alcoholic beverages at drive-up windows, lax enforcement of DWI laws, and even state legislators with DWI records. Theoretical bases upon which NMAIC goals and strategies were based include the public health model, the public health/dynamic systems, model of alcohol and other drug use, and 'refocusing upstream,' all of which give attention to the environment as a determinant of health status. IMPLEMENTATION. While the NMAIC's activities addressed a variety of alcohol-related problems in New Mexico, the bulk of the organization's efforts for four years were directed toward increasing the excise tax on alcohol, either as a statewide measure or via county-level local option referenda. Strategies which were enacted to support this legislative activity included collaboration with other programs and organizations with similar DWI-prevention goals, and staged media events to solicit public support. IMPACT. In four years, the NMAIC had established itself as a credible organization which was successful in publicly and systematically challenging existing alcohol policies in New Mexico. The NMAIC was also instrumental in empowering individuals and communities to speak and act against the alcohol problems in their own communities. Finally, during the 1993 New Mexico Legislative Session, a bill was passed which mandated a statewide excise tax increase on alcohol. For its efforts, the NMAIC has won one national level award and one state level award for its contribution to the public health of New Mexico. DISCUSSION. The NMAIC is now pursuing passage of the local option version of the excise tax increase bill, because it could generate up to three times as much revenue as the new statewide increase. Additionally, Consortium members have escalated discussions regarding nonprofit status for the NMAIC, and developing a more formal mechanism for determining leadership. Members continue their participation in trainings on community organizing, media advocacy, and alcohol policy reform.

The University of New Mexico Visiting Physicians Program: helping older New Mexicans stay at home.

New Mexico is a rural state with unique barriers to health service delivery to homebound elderly. The University of New Mexico's Visiting Physicians Program allows these patients to stay in their homes by bringing physicians to them. The physicians use community agencies to provide nursing, lab, X-ray, and physical therapy services. The University of New Mexico has also integrated home visits into the medical students, residents and geriatric fellows' educational programs. By involving medical students, residents and fellows in home care, future physicians who practice in New Mexico will incorporate this valuable service into care for the homebound elderly in their practice communities.
