Background: In conflict-affected settings, access to health care for displaced populations is constrained by barriers including geographical, cultural, communication, logistical, financial and insecurity. A six year humanitarian crises in the North West and South West regions of Cameroon has caused 27% of health facilities to be non-functional. The eleven year crisis in North-East Nigeria, has caused the closure of 26% of health facilities. These closure of health facilities and population displacement led to health care delivery using humanitarian funding by multiple different agencies. However, there is a paucity of evidence on the selection and design of the primary health care delivery models used in humanitarian settings. To ensure efficient use of resources and quality of services, model of care selection should be evidence based and informed by the specific humanitarian context. This research protocol aims to explore how primary health care models are selected by humanitarian organizations., Methods: We will conduct a cross sectional quantitative survey to map the range of primary health care delivery models used by humanitarian organisations in Cameroon and Nigeria. Using in-depth interviews and focus group discussions with staff from humanitarian organizations and internally displaced persons, we will explore the factors influencing the selection of primary health care models in these settings and determine the coverage and gaps in services across the different primary health care models. Quantitative data will be analysed in a descriptive manner and qualitative data will be analysed thematically., Discussion: Different models of care have been reported to be used by humanitarian organisations in conflict-affected settings, yet evidence on how different models are selected is lacking. A detailed understanding of the rationale for selection, the design and quality considerations of the strategies used to deliver health care will be obtained using a survey, in-depth interviews and focus group discussions., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Omam et al.

Self-collected specimens can expand access to SARS-CoV-2 testing. At a large inner-city hospital 1,082 participants self-collected saliva and anterior nasal swab (ANS) samples before healthcare workers collected nasopharyngeal swab (NPS) samples on the same day. To characterize patient preferences for self-collection, this investigation explored ability, comfort, and ease of ANS and saliva self-collection for SARS-CoV-2 testing along with associated patient characteristics, including medical history and symptoms of COVID-19. With nearly all participants successfully submitting a specimen, favorable ratings from most participants (at least >79% in ease and comfort), and equivocal preference between saliva and ANS, self-collection is a viable SARS-CoV-2 testing option., Competing Interests: The authors have declared that no competing interests exist.
