Community based research network: opportunities for coordination of care, public health surveillance, and farmworker research.

INTRODUCTION: The lack of aggregated longitudinal health data on farmworkers has severely limited opportunities to conduct research to improve their health status. To correct this problem, we have created the infrastructure necessary to develop and maintain a national Research Data Repository of migrant and seasonal farmworker patients and other community members receiving medical care from Community and Migrant Health Centers (C/MHCs). Project specific research databases can be easily extracted from this repository. METHODS: The Community Based Research Network (CBRN) has securely imported and merged electronic health records (EHRs) data from five geographically dispersed C/MHCs. To demonstrate the effectiveness of our data aggregation methodologies, we also conducted a small pilot study using clinical, laboratory and demographic data from the CBRN Data Repository from two initial C/MHCs to evaluate HbA1c management. RESULTS: Overall, there were 67,878 total patients (2,858 farmworkers) that were seen by two C/MHCs from January to August 2013. A total of 94,189 encounters were captured and all could be linked to a unique patient. HbA1c values decreased as the number of tests or intensity of testing increased. CONCLUSION: This project will inform the foundation for an expanding collection of C/MHC data for use by clinicians for medical care coordination, by clinics to assess quality of care, by public health agencies for surveillance, and by researchers under Institutional Review Board (IRB) oversight to advance understanding of the needs and capacity of the migrant and seasonal farmworker population and the health centers that serve them. Approved researchers can request data that constitute a Limited Data Set from the CBRN Data Repository to establish a specific research database for their project.

Asthma prevalence and risk factor assessment of an underserved and primarily Latino child population in Colorado.

Asthma is a substantialpublic health burden among children. Disease and risk-factor discrepancies have been identified among racial, ethnic, and socioeconomic groups. At a rural health clinic (Salud Family Health Center) with primarily underserved and Latino patients in Colorado, the authors evaluated 250 medical records and administered 57 parental surveys to describe this population with respect to asthma diagnosis, asthma-like symptoms, and environmental/occupational risk factors among children. Wheeze and asthma were indicated in 9.7% and 8.9% of medical records, respectively. Twenty parents (35.7%) reported in a questionnaire that their child had experienced wheezing or whistling in the chest. Parents reported that children play in farming fields (21.8%) and feed livestock/animals (10.9%). Additionally, 13.2% and 9.4% of children have a household member who works around livestock or around grain, feed, or dust, respectively. Information from the Salud population can be used to develop larger-scale research and public health initiatives to eliminate health and risk factor disparities among underserved children.

Safety practices in relation to home ownership among urban Mexican immigrant families.

UNLABELLED: We examined home safety hazards, comparing renter- to owner-occupied housing among urban, immigrant Mexican families. METHODS: Interviews and home inspections were conducted among urban, Spanish-speaking immigrant families with children. We estimated weighted hazard prevalence and used logistic regression to compare owner- and renter-occupied homes. Of 313 eligible households, 250 (80%) enrolled. Respondents were predominantly Mexican-born (99%), low income (72.6%) and lower education (92.3%). Most homes had fire, burn, fall, poisoning, electrocution and fire escape hazards, including high tap water temperatures (76.4%; 95% CI: 69.0, 83.7%), no working smoke alarms (60.0%; 51.3, 68.8%), slippery bathtub/shower surfaces (58.7%; 49.9, 67.5%), blocked fire escape routes (55.9%; 47.2, 64.5%) and child-accessible medications (71.0%; 60.1, 81.3%). After adjustment for sociodemographics, fire escape (OR = 8.8; 95% CI: 2.8, 27.7), carbon monoxide poisoning (OR = 2.9; 1.4, 6.2) and drowning (OR = 3.5; 1.3, 9.4) hazards were more likely in owner- than renter-occupied homes. Housing age and type explained most differences. Many urban, immigrant Spanish-speaking families live in unsafe homes. For this population, housing safety programs should be targeted based on housing age and type rather than tenure.

Housing environments and child health conditions among recent Mexican immigrant families: a population-based study.

The influx of immigrants to urban areas throughout the United States has raised concerns about accessibility of safe, affordable housing and the health consequences of poor-quality housing, particularly among immigrant children. We conducted a population-based study of home environmental conditions among recently immigrated Mexican families (weighted n = 473), generally of low socioeconomic status, and the health conditions of their children, in an urban industrial area north of Denver, Colorado. The majority of recent immigrants had low socioeconomic status; virtually all had household incomes below the Colorado median ($50,841). Approximately one quarter of homes were overcrowded. Adverse environmental conditions were present across recent immigrant homes. These conditions include dampness or mold (44%), pests (28%), and minimal to no ventilation potential (26%), all of which are associated with asthma and atopic diseases. At least one of these three environmental hazards was found in 67% of homes; multiple hazards were present in 27% of homes. Children of recent immigrant families had active symptoms within the past 12 months suggestive of asthma (4%) and atopic disorders (10%); however, fewer than 2% had been diagnosed with these conditions. The prevalence of asthma and atopic symptoms among Mexican immigrant children, albeit lower than in other low income and minority communities, is partially explained by housing conditions. Many of the conditions identified (e.g., pest infestation, mold resulting from plumbing leaks, and lack of exhaust fans) are amenable to low cost interventions. Solutions to address unhealthy housing conditions among recent immigrants must be multi-faceted and include strategies that target household-level improvements and access to health care.
