Systematic review Palliative care utilisation globally by cancer patients: systematic review and meta-analysis

Abstract

Introduction The rising global prevalence of cancer reveals significant regional disparities in palliative care adoption. While some countries have incorporated palliative care into their systems, over half of the world lacks such services, and oncology-specific palliative care integration is sparse. This study evaluates the global prevalence of palliative care use among cancer patients. Methods A comprehensive search across multiple databases was conducted to identify relevant studies. Data extraction and organisation were managed using Microsoft Excel, and analysis was performed with STATA/MP 17.0. A weighted inverse variance random-effects model was applied, and heterogeneity was assessed with Cochrane I2 statistics. Subgroup analyses, sensitivity analyses and Egger’s test were used to explore heterogeneity, publication bias and influential studies. Results The global prevalence of palliative care among cancer patients was 34.43% (95% CI: 26.60 to 42.25). Africa had the highest utilisation rate at 55.72% (95% CI: 35.45 to 75.99), while the USA had the lowest at 30.34% (95% CI: 19.83 to 40.86). Studies with sample sizes under 1000 showed a higher utilisation rate of 47.51% (95% CI: 36.69 to 58.32). Approximately 55% (95% CI: 35.26 to 74.80) of patients had a positive attitude towards palliative care, and 57.54% (95% CI: 46.09 to 69.00) were satisfied with the services. Positive attitudes were significantly associated with higher palliative care utilisation. Conclusion Only about one-third of cancer patients globally receive palliative care, with the highest utilisation in Africa. Nearly half of patients have a favourable attitude towards palliative care, and a similar proportion are satisfied with the services.
