Systematic Review of 81,167 Caregivers Confirms Low Uptake of Psychological Support Despite High Need

The University of Sydney and Queensland analysis aggregated data from Europe, North America and Australia spanning 2005-2025. Caregivers were mostly female partners of cancer patients; they reported needs for help with grief, role changes and sexual-relationship strain. Only 9 percent accessed social-work support despite 18 percent expressing interest, and government services reached just 10 percent of the 40 percent who wanted them. Professional referral markedly increased uptake, yet such offers remained rare under patient-centric models.

Related observational cohorts in JAMA Oncology and The Lancet Public Health show similar patterns: younger, educated women are likeliest to engage services, while financial and identity barriers suppress demand. These studies also document elevated caregiver mortality risk when support is absent, extending the Sydney findings beyond self-report.

Health-system reliance on unpaid care without reciprocal infrastructure creates predictable downstream costs in readmissions and lost productivity. Routine screening at oncology or cardiology visits plus automatic referral pathways could close the gap; pilot programs in Canada have raised access rates above 25 percent within 18 months.

Next steps require cluster-randomized trials that test whether mandated caregiver assessment alters service use and caregiver health outcomes at two-year follow-up.
