Creation and testing of the Domiscore-a tool to characterize the impact of housing on health and well-being.

BACKGROUND: Despite evidence of the major impact housing carries on health, many individuals still live in unhealthy dwellings. In France, the Domiscore has been proposed as a tool to assess the quality of dwellings with regard to their health impact, to allow for a better detection of unsafe housing and to improve dwellings. The aim of this paper is to present the method used to construct the Domiscore and test its relevance and usability. METHODS: The Domiscore grid, inspired by the Nutriscore, consists of 46 variables-such as air quality, light or outdoor view. Each variable is scored on a four-point scale using in situ observation, mandatory diagnostics and open access data. The sum of each variable's score results in an overall risk score for the dwelling. The Domiscore was tested in two phases. During the first testing phase, 11 real estate professionals, health professionals and social workers used the Domiscore for on-site visits in different geographic areas of France. They then participated in a semi-structured qualitative interview. The second phase consisted in a public consultation with diverse stakeholders such as public authorities, housing activists and social workers, using an online survey to collect their opinions on the Domiscore's relevance, understandability and usability. RESULTS: The Domiscore was tested on 28 homes. Variables completion rates were high irrespective of tester profile for all home visits (91%, SD = 4.7%). The mean time needed to fill in the grid was 1.5 h. The public consultation returned 151 responses. The Domiscore was deemed easy to understand, relevant, and rather easy to fill out. Most participants found the Domiscore useful for information gathering, awareness raising, detecting at-risk situations and agreed that it could contribute to enhance housing conditions. Its length was noted, although the inclusion of additional variables was also suggested. CONCLUSIONS: The results of this study suggest that the Domiscore is accessible to housing specialists and other professionals for the evaluation of a dwelling's health impacts and the standardized detection of dangerous situations. The testing process allowed for improvements in the grid and training materials for future users.

Interaction between science advice and policymaking in time of COVID-19: a French perspective.

BACKGROUND: In the coronavirus disease 2019 (COVID-19) context, many governments relied on scientific consultative bodies to advise their policy, but their contribution remains poorly documented. This article aims to fill this gap by reviewing the role played by the French High Council for Public Health (HCSP) in the French government's response to COVID-19. METHODS: We studied the time distribution of the COVID-19 guidelines produced by the HCSP until November 2020, computed their delay of production and analyzed the thematic areas they cover. To assess their use by the authorities, we looked for references to these guidelines in the regulatory texts, protocols and press communicates issued by national and local authorities until January 2021. RESULTS: The HCSP was strongly demanded with 102 guidelines produced following 97 official requests and two self-referrals. Most of them (N = 43) concerned protective measures to constrain the infection, while health inequalities and mental health were poorly addressed. Timing was very constraint as half of the guidelines were requested within 4 days. In total, 73% of the guidelines were used by policymakers to implement new obligations or within communication toward the public at national and local levels. CONCLUSIONS: This article informs on the HCSP's contribution during the crisis and stresses the difficulties it encountered to provide quality recommendations in very short times. It prompts governments to enlarge the competencies of their advisory boards and to consider the multidimensional aspects of health in policy design.
