How did living in temporary accommodation during the COVID-19 pandemic affect children younger than 5 years' access to health care and health outcomes? A qualitative study of key professionals in a socially and ethnically diverse and deprived area of London

BACKGROUND: Children younger than 5 years living in temporary accommodation due to homelessness (U5TA) are extremely vulnerable to the effects of the COVID-19 pandemic. Few qualitative studies have examined provider perspectives in family homelessness, but none focused on U5TA specifically. We aimed to qualitatively explore professionals' perspectives of pandemic-related challenges and barriers experienced by U5TA in accessing health care and optimising health outcomes, and their experiences of delivering U5TA services. METHODS: 16 semi-structured interviews were done online. Professionals working in the London Borough of Newham with U5TA families were purposively sampled and recruited from non-profit organisations, the health sector, and local authority. A thematic codebook approach was used to analyse the data combining inductive and deductive codes using an adapted socioecological model as a guiding theoretical framework. FINDINGS: Two non-profit organisation professionals, seven health visitors, one GP, therapist, dietician, nurse, public health consultant, and two social workers from the local authority's No Recourse to Public Funds team described adverse pandemic effects on U5TA health: delay and regression in developmental milestones and behaviours—eg, toileting, feeding skills, emotional regulation, and social-communication skills. Pre-existing systemic barriers were exacerbated during the pandemic when the reduction of in-person services with professionals necessitated remote delivery of health and social care services. Differential effects of digital poverty, language discordance, and inability to register and track U5TA rendered this population invisible to services. Professionals highly agreed that barriers to optimal health outcomes and service access included poor mental health, unsuitable housing, no social support, mistrust of mainstream services, immigration administration, financial insecurity, and loss of informal jobs among U5TA families. Professionals sometimes mitigated these barriers with good communication skills, developing trusting relations, and through community facilitators. INTERPRETATION: COVID-19 widened health inequalities and inequities, substantially affecting the lives of U5TA and ability of professionals to deliver quality care to U5TA. Innovative and tailored cross-sector strategies, including co-production of public health services, are required. Policies and services urgently need to focus on early development, mental health support, employment training, and opportunities for parents and carers, plus unambiguous definitions of what is deemed suitable accommodation and actionable planned steps to ensure enforcement. FUNDING: None.
