Racial Disparity in Oxygen Saturation Measurements by Pulse Oximetry: Evidence and Implications.

The pulse oximeter is a ubiquitous clinical tool used to estimate blood oxygen concentrations. However, decreased accuracy of pulse oximetry in patients with dark skin tones has been demonstrated since as early as 1985. Most commonly, pulse oximeters may overestimate the true oxygen saturation in individuals with dark skin tones, leading to higher rates of occult hypoxemia (i.e., clinically unrecognized low blood oxygen saturation). Overestimation of oxygen saturation in patients with dark skin tones has serious clinical implications, as these patients may receive insufficiently rigorous medical care when pulse oximeter measurements suggest that their oxygen saturation is higher than the true value. Recent studies have linked pulse oximeter inaccuracy to worse clinical outcomes, suggesting that pulse oximeter inaccuracy contributes to known racial health disparities. The magnitude of device inaccuracy varies by pulse oximeter manufacturer, sensor type, and arterial oxygen saturation. The underlying reasons for decreased pulse oximeter accuracy for individuals with dark skin tones may be related to failure to control for increased absorption of red light by melanin during device development and insufficient inclusion of individuals with dark skin tones during device calibration. Inadequate regulatory standards for device approval may also play a role in decreased accuracy. Awareness of potential pulse oximeter limitations is an important step for providers and may encourage the consideration of additional clinical information for management decisions. Ultimately, stricter regulatory requirements for oximeter approval and increased manufacturer transparency regarding device performance are required to mitigate this racial bias.

The Flint women's study: community perspectives on contraception and family planning, sexuality education and barriers to reproductive health.

Teenage pregnancy can have adverse social and health outcomes, and rates are high in Flint, Michigan as compared to the rest of the state and the USA. It is important to understand contributing factors to adolescent pregnancy to be able to better address this issue. This study examined qualitative data from interviews with 100 community members who participated in the Flint Women's Study, a study designed to better understand the hopes, dreams and needs of women in Flint, and their suggestions for how to address identified needs. Using a Community Based Participatory Approach, data were collected and analysed by a team of community members and academic researchers. The paper focuses on the theme of family planning among young women which included attitudes about contraception, sexuality education and bio-medical and structural barriers to accessing reproductive health. Community members emphasised the need for increased access to comprehensive contraception options, improved sexuality education in schools and from health care providers, and ultimately valuing young women.

Intersectionality, special populations, needs and suggestions: the Flint Women's study.

BACKGROUND: Equitable access to services that promote health and wellbeing is an important component of social justice. A community-engaged participatory qualitative study was conducted in Flint, Michigan, USA, to understand the needs of special populations (young women, perinatal women and new mothers, older women, women with disabilities, and LGBTQIA women) and elicit their ideas about solutions. METHODS: In-depth interviews (n = 100) were conducted. Participants were either women living in the Flint area, human service providers in the area, or both. A team of community and academic coders analyzed the data using an a priori framework. RESULTS: Participants identified needs of different groups of women and suggested ways to address them. Access to healthy food, reducing healthcare costs, and improving transportation, job opportunities and affordable quality housing were crosscutting themes across all groups of women. Mentoring support was said to protect vulnerable young women from the risk of human trafficking. Older women were said to gain a sense of purpose, build their social support and reduce their loneliness by engaging in mentoring younger women. Women with disabilities were reported to benefit from infrastructure accessibility and authentic inclusion in all areas of life. Providing help that considers their dignity, pride and self-worth were suggested. LGBTQIA women were reported to have housing needs due to discrimination; mostly turned down as renters and can be rejected from faith-based homeless shelters. LGBTQIA women would also benefit from increased sensitivity among healthcare providers. For all groups of women, streamlining access to social services and other resources, building social support networks and increasing awareness about existing resources were recommended. CONCLUSION: Efforts directed towards improving women's health and wellbeing should include perspectives and suggestions of diverse groups of women from the community. Acting on suggestions that emanate from the community's lived experiences may reduce inequalities in health and wellbeing.
