Calculating Social Work Safe Staffing Caseloads in Children’s and Older People Services in Northern Ireland: A policy development approach

Safe staffing is critical to effective social work practice, workforce sustainability, and staff well-being. Unlike other health and social care professions, social work lacks mandated staffing levels or caseload benchmarks, contributing to workload strain, burnout, and inconsistent service delivery. Using a qualitative narrative approach, expert steering groups from all five Health and Social Care Trusts in Northern Ireland analysed time allocations for minor, moderate, and complex cases. Weighted analysis (70% complex, 20% moderate, 10% minor) reflected real-world caseload compositions and informed workload modelling across children’s and older people’s services. Indicative safe caseload ranges were identified as 13-15 for Family Intervention Teams, 8-12 for Gateway Teams, 12-18 for Looked After Children Teams, and 30-39 for Older People’s Community Services. Thematic analysis highlighted increasing case complexity, administrative burden, and the importance of supportive communication and supervision. Findings provide an evidence base for emerging Department of Health (NI) policy on safe staffing. Embedding caseload standards, improving data consistency, and reducing bureaucratic pressures are essential to workforce reform. This study advances operationalisation of safe staffing levels in social work, strengthening policy, legislation, and sustainable practice.
