Abstract
BACKGROUND: As the acute response to the COVID-19 pandemic shifts to long-term management, the lasting effects of infection are becoming increasingly evident. Long COVID continues to challenge healthcare systems, with many healthcare professionals reporting uncertainty about assessment and referral pathways. This updated review examines recent international guidelines alongside Australian services to identify gaps between guidelines and practice. METHODS: Between April and October 2025, we searched for guidelines on Long COVID published in English and assessed their quality by applying the AGREE II appraisal tool. We also conducted a grey literature search to profile active Australian services providing Long COVID care. RESULTS: Three new or updated guidelines were published in the United States, Canada, and New South Wales, Australia. Together with the World Health Organisation, United Kingdom and New Zealand guidelines identified in the previous review, all emphasise integrated, primary care-led approaches. Notably, Australian service delivery remains fragmented, with a growing number of primary health practitioner-led private services operating largely under a fee-for-service model, leading to variations in access and affordability. Many hospital-based outpatient clinics have been absorbed into existing chronic-disease services. The most fundamental challenge is statistical invisibility: without an activated diagnostic code, services cannot reliably identify or follow people living with Long COVID. This invisibility limits both surveillance and service planning. DISCUSSION AND CONCLUSIONS: Australia is currently developing national clinical best-practice guidelines for ME/CFS, which may also benefit Long COVID; however, Australia remains behind comparable nations such as Canada, the United Kingdom, and the United States in developing and implementing the integrated, multidisciplinary care models recommended internationally. This has significant implications, namely that the rapid transition from hospital-based Long COVID clinics to primary care-led services has resulted in fragmented and uncoordinated care. Strengthening Australia’s response will require national leadership and investment in workforce training, sustainable funding for care coordination, improved public and professional awareness, the establishment of primary care-led multidisciplinary pathways, and the activation of a dedicated diagnostic code. Also importantly, shifting to a patient-centred approach and patient-practitioner collaborative model of care is essential to prepare the health system for managing Long COVID and future complex, multi-system conditions.
