Time-to-Treatment for Myocardial Infarction: Barriers and Facilitators Perceived by American Indians in Three Regions.

Early recognition of acute myocardial infarction (MI), followed by prompt emergency care, improves patient outcomes. Among rural American Indian (AI) populations there are disparities in access to care for MI and processes of care, resulting in poor MI-related health outcomes compared to the general population. We sought to gain an understanding of barriers related to MI time-to-treatment delays using a qualitative approach. We conducted semi-structured interviews and focus groups with AI key informants and community members in three Indian Health Service regions. Major barriers to care included long travel distance to care and lack of supporting infrastructure; distrust of the health care system; low overall literacy and basic health literacy; priority of family care-giving; and lack of specialized medical facilities and specialists. Findings suggest that improved time-to-treatment facilitators include educating the local community about the causes and consequences of MI and culturally-sensitive health communication, as well as addressing the quality of local systems of care and the community's perception of these systems. Pursuing these strategies may improve quality of care and reduce MI-related morbidity and mortality in rural AI populations.

Historical trends and regional differences in all-cause and amenable mortality among American Indians and Alaska Natives since 1950.

American Indian and Alaska Native (AI/AN) death rates declined over most of the 20th century, even before the Public Health Service became responsible for health care in 1956. Since then, rates have declined further, although they have stagnated since the 1980s. These overall patterns obscure substantial regional differences. Most significant, rates in the Northern and Southern Plains have declined far less since 1949 to 1953 than those in the East, Southwest, or Pacific Coast. Data for Alaska are not available for the earlier period, so its trajectory of mortality cannot be ascertained. Socioeconomic measures do not adequately explain the differences and rates of change, but migration, changes in self-identification as an AI/AN person, interracial marriage, and variations in health care effectiveness all appear to be implicated.

Trends and disparities in stroke mortality by region for American Indians and Alaska Natives.

OBJECTIVES: We evaluated trends and disparities in stroke death rates for American Indians and Alaska Natives (AI/ANs) and White people by Indian Health Service region. METHODS: We identified stroke deaths among AI/AN persons and Whites (adults aged 35 years or older) using National Vital Statistics System data for 1990 to 2009. We used linkages with Indian Health Service patient registration data to adjust for misclassification of race for AI/AN persons. Analyses excluded Hispanics and focused on Contract Health Service Delivery Area (CHSDA) counties. RESULTS: Stroke death rates among AI/AN individuals were higher than among Whites for both men and women in CHSDA counties and were highest in the youngest age groups. Rates and AI/AN:White rate ratios varied by region, with the highest in Alaska and the lowest in the Southwest. Stroke death rates among AI/AN persons decreased in all regions beginning in 2001. CONCLUSIONS: Although stroke death rates among AI/AN populations have decreased over time, rates are still higher for AI/AN persons than for Whites. Interventions that address reducing stroke risk factors, increasing awareness of stroke symptoms, and increasing access to specialty care for stroke may be more successful at reducing disparities in stroke death rates.

Trends and disparities in heart disease mortality among American Indians/Alaska Natives, 1990-2009.

OBJECTIVES: We evaluated heart disease death rates among American Indians and Alaska Natives (AI/ANs) and Whites after improving identification of AI/AN populations. METHODS: Indian Health Service (IHS) registration data were linked to the National Death Index for 1990 to 2009 to identify deaths among AI/AN persons aged 35 years and older with heart disease listed as the underlying cause of death (UCOD) or 1 of multiple causes of death (MCOD). We restricted analyses to IHS Contract Health Service Delivery Areas and to non-Hispanic populations. RESULTS: Heart disease death rates were higher among AI/AN persons than Whites from 1999 to 2009 (1.21 times for UCOD, 1.30 times for MCOD). Disparities were highest in younger age groups and in the Northern Plains, but lowest in the East and Southwest. In AI/AN persons, MCOD rates were 84% higher than UCOD rates. From 1990 to 2009, UCOD rates declined among Whites, but only declined significantly among AI/AN persons after 2003. CONCLUSIONS: Analysis with improved race identification indicated that AI/AN populations experienced higher heart disease death rates than Whites. Better prevention and more effective care of heart disease is needed for AI/AN populations.

Heart disease mortality among Alaska Native people, 1981-2007.

OBJECTIVES: Historically, Alaska Native (AN) people have exhibited low overall rates of heart disease mortality compared with the U.S. white (USW) population. We compared AN and USW heart disease mortality rates during the 27-year period from 1981 through 2007. METHODS: We compared AN and USW heart disease mortality rates overall and by gender, age, and disease subtype. We calculated age-adjusted rates for AN people for three nine-year periods from 1981 through 2007 and compared them with the rates for USW people. RESULTS: AN people > or = 35 years of age had a significantly lower rate of heart disease mortality compared with their USW counterparts (rate ratio [RR] = 0.80). The lower overall RR was due primarily to a lower ischemic heart disease mortality RR (RR = 0.63). Overall heart disease mortality decreased during the 27-year study period for both the AN (33.1%) and USW (35.0%) populations. However, hypertensive heart disease mortality increased 155.2% for AN people and 13.7% for USW people. Age-specific heart disease mortality was about 30.0% lower for AN people > or = 75 years of age compared with their USW counterparts, while it was virtually identical for the two racial/ethnic groups among people 35-74 years of age. CONCLUSIONS: The age-adjusted AN heart disease mortality rate was consistently about 20.0% lower than the USW rate from 1981 through 2007, with similar RRs for men and women. However, combining all ages and all heart disease subgroups into a single, age-adjusted statistic obscures many important differences across ages and disease subtypes.

The use of sentinel injury deaths to evaluate the quality of multiple source reporting for occupational injuries.

PURPOSE: This study sought to develop an efficient method for evaluating the validity and completeness of routinely available sources of occupational injury fatality data. METHODS: Deaths due to falls from elevations, machinery, and electrocutions were selected as sentinel injuries likely to have occurred at work. Deaths from these injuries were identified from Maryland vital statistics over 7 years. The work-relatedness of these injuries and sensitivity of reporting were determined from death certificates, medical examiner reports, the National Traumatic Occupational Fatality System (NTOF), the Maryland Occupational Safety and Health Administration (MOSH), and Workers' Compensation (WC) data. RESULTS: A total of 527 deaths were identified for ages 16 and above, of which, 45% were work-related. Identification of work-related deaths varied by source: medical examiner (100%), death certificates (89%), NTOF (68%), MOSH (59%), and WC (44%). Reporting differed by age, cause of injury, year, occupation, and industry. CONCLUSIONS: Examination of work-relatedness for deaths from certain causes is an efficient means of evaluating the quality of occupational injury reporting source data. These sentinel injuries uncovered significant underreporting in sources used by national surveillance systems, resulted in improved NTOF reporting, and suggest the need to make more use of medical examiner data when available.

Building community capacity around chronic disease services through a collaborative interorganizational network.

This article presents the findings of a study examining the evolution of a network of health and human service organizations operating in a rural community on the Southwest border. The aim of the network was to build the capacity of the community to provide chronic disease education, prevention, and treatment services by developing collaborative relationships among a broad range of organizations. The impetus for the effort was based on receipt of a Turning Point grant. The findings, based on two waves of data collected 1 year apart, demonstrate how network structure and attitudes toward collaboration evolve as a community attempts to build capacity to address its health needs.

Network analysis as a tool for assessing and building community capacity for provision of chronic disease services.

A network analysis was conducted in spring 2000 by the Southwest Center for Health Promotion in the U.S.-Mexico border community of Douglas, Arizona. The purpose of the analysis was to assess the level of collaboration among the 23 public and not-for-profit agencies that provided health and human services for a broad range of chronic disease prevention, screening, and treatment services. Data were also collected on levels of trust and anticipated outcomes (benefits and draw-backs) of collaboration. The article presents the findings of the network analysis, focusing on its usefulness as a tool for evaluating efforts at building community capacity through enhanced interagency collaboration.

Adaptation of the OODA Loop to reduce postoperative nausea and vomiting in a high-risk outpatient oncology population.

Postoperative nausea and vomiting (PONV) remains a ubiquitous concern for surgical outpatients with published rates ranging from 14% to 80%. An evidence-based approach was used to reduce PONV in a high-risk adult outpatient oncology population. The Observe, Orient, Decide, and Act (OODA) Loop, a rapid cycle management strategy, was adapted for use in an outpatient surgery center with six ORs. A PONV prophylaxis protocol was developed and adapted until a stable PONV rate was achieved. A combination of dexamethasone, promethazine, and ondansetron was used in patients with one to three PONV risk factors. Patients with four major risk factors received an additional intervention. The PONV rate for the final protocol stabilized below 4% by 46 weeks and remained stable through 79 weeks. The OODA paradigm provides an effective technique for interfacing health care research with clinical practice. In this case, an effective PONV prophylaxis plan was developed from within a collaborative nursing and medical setting.
