Co-developing a tailored vaccination intervention with Congolese migrants: a participatory study

Abstract Background Disparities in vaccination uptake among migrant populations are well documented. WHO and ECDC have sought renewed focus on participatory research that engages migrants in co-producing tailored initiatives to address vaccination inequities and increase coverage. Methods This community-based participatory research study aims to engage Congolese migrants in co-developing a tailored approach to increase vaccine uptake. Phase 1 used poster walls and in-depth interviews with Congolese migrants (n = 32) to explore COVID-19 vaccination beliefs, experiences, and preferred information sources and communication methods, analysed iteratively and thematically in NVivo. Preliminary results Institutional distrust has shaped this population’s interpretation of the pandemic response and enabled vaccine misinformation and conspiracy theories to take hold. We found complex information networks and preference for Francophone, African and social media. Limited English proficiency and preference for the oral tradition restricted engagement with official public health messaging. Suspicion of government motives, low knowledge, and culturally specific perceptions about vaccination contributed to belief that breakthrough infections and need for COVID-19 boosters imply the vaccine is not effective. The population felt coerced by vaccination reminders and mandates, and were resultantly more hesitant to accept COVID-19 vaccination. Conclusions The population’s specific characteristics suggest that existing and trusted interpersonal networks and oral communication in first languages should be harnessed to spread credible information and encourage vaccine uptake, and mandate policies are unlikely to be effective. Training local role models to facilitate vaccination dialogues and myth-bust may be effective at changing behaviour. The next phases will gather more information from key stakeholders and engage migrants in workshops to co-design insight-driven, tailored interventions. Key messages • Global policy-setting organisations have called urgently for participatory research that engages migrants in the co-production of tailored initiatives to address vaccination inequalities. • Populations with strong interpersonal networks and low trust in public institutions may be receptive to tailored, community-centred dialogue approaches using local messengers and role models.


Background:
The impact of racism on health and the quality of health care services for racialized patients have been the object of prior research. The experiences of racialized medical students and physicians, who operate in a field of tension between natural sciences and practical application and between a 'medical habitus' and exclusionary discrimination, have hardly been examined to date. The education of (future) physicians is an especially fruitful research area in the context of the study of institutional racism in the health care system, as informal everyday experiences come together with formal knowledge and normative learning. Methods: Based on expert consultations and preliminary interviews with civic stakeholders, teaching and learning materials in German medical studies were randomly sampled and used as a starting point for qualitative guided interviews with physicians and medical students in Germany who are themselves affected by racism. The first steps of the thematic analysis of these interviews are reflected upon and further developed in focus group discussions with the interviewees.

Results:
The study is particularly concerned with the question of how certain dimensions of racism in the health care sector are related, and how racist normativity appears in this context. This is concretized in the relationship between formal and informal medical curricula as well as in the interweaving of everyday experiences and teaching materials.

Conclusions:
There are different dimensions of relation between a hegemonic normativity in the medical curriculum and the everyday experiences of racialized medical students and physicians in Germany. Politics, faculties, publishers, and civic society may be the target of several recommendations for action regarding those diverse dimensions, e.g. the line between omission and stereotyping of several patient groups. Key messages: Hegemonic normativity in German medical education is an important and challenging issue. There are several institutional levels of medical knowledge reproducing racism in the health care sector. Both racialized physicians and racialized patients are affected by symbolic and material forms of racism in the German health care system, which are interweaving and crucial on diverse levels.

Objective:
To construct an individual socioeconomic status index (ISESI) with information available in the Population Information System of the Region of Valencia, Spain, and use it to analyse inequalities in a colorectal cancer screening programme (CRCSP).

Methods:
Cross-sectional study. The study population was composed of men and women aged between 50 and 69 who were invited to participate in the most recently completed round of the Region of Valencia CRCSP in 2020, n = 1,150,684. A multiple correspondence analysis was performed to aggregate information in the Segmented, Integrated and Geographical Population Analysis Code from the Population Information System of the Region of Valencia into an ISESI. Data from the 2016 Region of Valencia Health Survey was used for validation. The relationship between CRCSP participation and the ISESI was analysed by logistic regression models.

Results:
The variables included in the index were nationality, employment status, disability, healthcare coverage, risk of vulnerability and family size. The most important categories for determining the highest socioeconomic status were being employed and not being at risk of social vulnerability, and being unemployed and at risk of social vulnerability for determining the lowest socioeconomic status. Index validation demonstrated internal and external coherence for measuring socioeconomic status. The relationship between CRCSP participation and the ISESI categorised by quartile (Q) showed that Q4 (the lowest socioeconomic status) was less likely to participate OR = 0.769 (0.757-0.782) than Q1 (the highest socioeconomic status), and the opposite was found for

Background:
Many countries agree with the horizontal equity that medical resources should be allocated according to medical needs, regardless of income. Although the short-term equity index calculated through cross-sectional data doesn't reflect the dynamics of individual income and medical use, it can be supplemented by the long-term equity index using panel data. Koreans tend to choose expensive but highly specialized services without considering their medical needs because they are free to choose service providers. This study aims to empirically examine how the patterns of outpatient medical use that are not based on medical needs differ in terms of short-and long-term equity for each type of medical institution.

Methods:
Using Korea Health Panel Survey(2014-2018), the equity of outpatient medical use(number of visits, medical expenses) of 10,244 people was measured by type of medical institution (tertiary general hospital, general hospital, hospital, clinic, and dentist). Wagstaff&van Doorslaer (2000)'s tool and Jones & Lopez-Nicolas(2004)'s tool were used to calculate the short and long-term horizontal equity index(HI), and mobility index(MI) to compare short and long-term inequity.

Results:
In tertiary general hospitals and dentists, there were short and long-term pro-rich inequalities(HI > 0, p < 0.05). As a result of comparison, long-term inequality was greater in the number of visits (MI < 0), while inequality was easing in the long-term in medical expenses(MI > 0) in tertiary general hospitals. In dentists, long-term inequality was less than short-term inequality in both the number of visits and medical expenses (MI > 0).

Conclusions:
The short-term equity index is likely to underestimate or overestimate inequity in our society, so a long-term perspective is needed. Inequality patterns for each type of medical institution should be considered in healthcare reforms for fair distribution of medical resources. Key messages: Short-term equity index differs from the long-term equity index in outpatient medical use. The pattern of short and long-term equity indices may differ by type of medical institutions.
