Health Disparities

The Institute for Health Research conducts studies to identify health disparities and interventions to reduce them for Kaiser Permanente members and the broader community in several areas of prevention and chronic disease treatment. The Centers for Disease Control and Prevention (CDC) defines health disparities as “preventable differences in the burden of disease, injury, violence, or opportunities to achieve optimal health that are experienced by socially disadvantaged populations”.

Ongoing studies include:

  • Multiple studies to improve the identification of disparities in basic resource needs such as housing, food, and transportation among Kaiser Permanente members and develop strategies to help members address those needs
  • An NIH-funded study to examine the social determinants of drug use risk behavior and overdose
  • A systematic review of research on disparities in opioid use disorder treatment access, retention, and outcomes
  • A study examining the risk of opioid overdose among people with a felony conviction

The Office of Health Equity’s (OHE) Health Disparities Community Grant Program (HDCGP) is providing support to organizations across Colorado to address upstream determinants of health (e.g., housing, education) with the goal of improving downstream health outcomes (e.g., access to care, decreased chronic disease rates). The goal of this project is to conduct a comprehensive cross-site evaluation of these funded organizations implementing system or policy changes that reduce health disparities (e.g., housing insecurity, food insecurity, unemployment). The evaluation is assessing the role of community engagement, community capacity building, and multisectoral partnerships in advancing the community’s collective action to solve problems and how that informed policy, environmental, and system changes designed to improve access to social and economic resources. Innovative methods have been developed to measure authentic community engagement and the role of partners and community members in making decisions. Additionally, an in-depth evaluation is being conducted to assess how the partnership network and community engagement helped drive the prioritization and adoption of PSE changes.

The goal of this project was to improve care for patients with hypertension at the First Nations Community HealthSource, an Urban Indian Health Organization in Albuquerque New Mexico. The study supported a randomized, controlled trial of interactive voice-response outreach to patients with hypertension, with the goal of improving blood pressure control through reducing missed clinic appointments and improving medication adherence.

The diversity supplement to the parent Naloxone trial aims to: 1) augment the parent trial database of EHR and survey data with social and environmental determinants of health 2) determine the predictive validity of risk behavior survey measures by examining associations between survey responses and measures of risk behavior from the EHR and 3) identify predictors of opioid risk behavior in trial eligible patients. It also supports post-doctoral training and career development of a research fellow.
