Although the acute disease burden of coronavirus disease 2019 (COVID‐19) in Australia has reduced, the longer term impacts are becoming increasingly apparent.1 The constellation of persistent symptoms is termed “post‐acute COVID‐19 condition”, also known as “long COVID”, and includes dyspnoea, fatigue, cognitive impairments, headaches, and psychiatric symptoms.2,3 The health impact at a population level is significant, with between 10% and 20% of people having persistent symptoms after a COVID‐19 infection.4,5

Impact of long COVID

Patient testimonies describe the devastating impact of symptoms left untreated by health services.6,7 The functional sequalae of long COVID include reduced quality of life8,9 and difficulty engaging in normal life roles, including family, work and caring responsibilities.10 COVID‐19 has also disproportionately affected disadvantaged communities who have less access to health care services and less resources to allow for absences from work.11

As the world has returned to normal, many people living with long COVID continue to report feeling left behind and isolated by persistent symptoms.12 Alongside this, many people report feeling ignored or not believed by health care providers, who often struggle to pinpoint physiological impairment and associated treatments.13 This can lead to a marked discordance between the lived experience of ongoing debilitation and the expectations of the community and health care sector of what recovery from COVID‐19 looks like.

Models of care

Initially, Australia's response to long COVID followed a specialist clinic model of care, including individual referrals to respiratory and cardiac specialists. With the emergence of milder acute illness, the model of care for long COVID in Australia has now moved to primary care, with general practitioners seen as the coordinators of ongoing services and interventions.14

Allied health multidisciplinary care

The heterogeneous nature of long COVID symptoms, coupled with no diagnostic tool or single treatment, means the functional burden of long COVID may best be addressed by symptom management approaches.15,16 In this regard, Australian and international guidelines recommend multidisciplinary and coordinated allied health care as a practice standard for people with long COVID,17,18 and there is emerging evidence of corresponding functional improvement.19,20 In line with these recommendations, the National Health Service in the United Kingdom encourages a three‐tiered approach to care, with multidisciplinary interventions offered to people with the most severe symptoms requiring input from two or more professionals, stepping down to community therapy teams, and then self‐management pathways for individuals with milder symptoms.21 In Australia, access to publicly funded allied health intervention for long COVID remains challenging with no system‐level coordinated care or funding.

The ReCOVery service at Austin Health

In early 2022, Austin Health in Melbourne commenced ReCOVery: an allied health‐led rehabilitation service aimed at providing multidisciplinary management for long COVID symptoms based on international evidence and guidelines translated into the Australian context.17,18 The key principles in the design of the service were (i) a stepped care model, with access to a multidisciplinary team for individuals with the most severe symptoms, and a self‐management pathway for those with less severe symptoms; (ii) symptom management, improved function and participation via coordinated goal‐driven allied health care, mainly offered via telehealth; (iii) care designed to complement rather than replace existing care pathways, such as pulmonary rehabilitation; and (iv) patients as partners in their care through shared rehabilitation goals. The team consisted of exercise physiology, clinical neuropsychology, occupational therapy, clinical psychology, nutrition and dietetics, speech pathology and rehabilitation medicine, who onward referred to other medical specialists as required. The Austin Health Human Research Ethics Committee (HREC 88943/Austin‐2022) provided approval for the service improvement audit presented.

Triage and assessment

ReCOVery opened during the third peak of COVID‐19 in early 2022. Initially, all previous COVID‐19‐positive Austin Health inpatients were contacted via SMS to offer intervention (Box 1). Along with this, referrals internally from specialist clinics and self‐referrals for any Austin Health staff affected by long COVID were accepted. Our system was designed to ensure timely access to care for individuals with the most severe symptoms. This involved:

  • completion of an online custom‐designed symptom severity assessment to establish symptom impact using a “mild”, “moderate” and “severe” grading (Supporting Information);
  • triaging of participants to access either independent education and resources for milder symptoms or an individual and group therapy program for participants experiencing moderate to severe symptoms; and
  • completion of an intake and goal‐setting appointment for rehabilitation plans for participants requiring multidisciplinary team assessment.

The service opened to referrals from general practitioners mid‐2022 and received on average one referral each day.

Participant profile

SMS messages were sent to 4480 former patients of Austin Health who had been treated for COVID‐19. About 40% of these patients (1708) responded, with 254 (15%) indicating they had ongoing symptoms. We additionally received 147 referrals (Box 2). Overall, we triaged and assessed 285 people, with 163 going on to receive individual therapy in the eight months the service operated.

Individuals accessing the service were more likely to be women (72%) and were of working age (average age 49 years) (Box 3). Participants reported that the impact of long COVID on their lives was profound. Self‐reported measurement of health‐related quality of life and physical and mental health on a 0–100 scale found a significant reduction across all measures since their COVID‐19 diagnosis (P < 0.001 for all).

Symptoms and service utilisation

The most common symptoms reported at a moderate to severe level were fatigue, brain fog and psychological impacts (Box 3). Most participants accessing the service were seen by more than one multidisciplinary team member (63%). Exercise physiology was the most in‐demand discipline, followed by clinical psychology and occupational therapy (Box 4). We had a low “fail to attend” rate at 7%. Individual discipline therapy was complemented by online self‐management resources22 and a bespoke virtual group program that was attended by 72 people. Groups consisted of single sessions on living with long COVID, olfactory impairment, brain fog, and managing fatigue.

Interventions

The evidence base for long COVID interventions is emerging, and interventions were based on clinical guidelines, such as the National Institute for Health Care and Excellence guidelines,17 that are mainly at the expert consensus or low level of evidence currently. As per these guidelines, the clinic interventions included (i) a one‐stop, coordinated approach to care; (ii) management of fatigue, brain fog, olfactory impairment, sleep and voice changes; (iii) clinical psychological support and intervention, including for adjustment to persistent symptoms, ongoing COVID‐19 and health anxiety, general psychological difficulties and exacerbation of pre‐morbid mental health concerns; (iv) investigation, diagnosis and management of postural orthostatic tachycardia syndrome in conjunction with hypertension specialist medical services; and (v) occupational therapy supporting functional improvement to allow people to return to important activities and life roles, such as work and caring responsibilities.

Recommendations

There are still relatively few Australian public health services to provide the recommended multidisciplinary care to people living with long COVID. Most people are unable to access rehabilitation services that could provide relief from symptoms, improve quality of life and support return to valued life roles. The ReCOVery model of care was developed using international guidelines and provided impactful care to participants. People accessing our service would otherwise most likely have fallen between the cracks of our health system, unable to access traditional post‐injury or acute rehabilitation services or aged care services. The ReCOVery model provides a viable blueprint for a stepped care approach to support patients, and provides initial evidence for allied health discipline requirements through our utilisation data. Despite this, funding for services has largely ceased across multiple public long COVID clinics in Victoria. This has compounded inequity in who can access care, with private allied health options being simply unaffordable to most people. Care plans for access to allied health services can be completed by a general practitioner but only provide five sessions, with gap fees being common.

Enablers and barriers

We were able to effectively run the ReCOVery service almost exclusively via telehealth. Centrally located telehealth hubs for long COVID would be a viable model to provide therapy to people who need it most. This telehealth model supports care by specialist disciplines that are difficult for most Australians to access, such as clinical neuropsychology. We acknowledge that people from culturally and linguistically diverse backgrounds and from disadvantaged communities may not have ready access to telehealth infrastructure, with centre‐based options needed for some. A tiered (stepped) approach to care is the most efficient and cost‐effective solution to management of long COVID and has been successfully implemented elsewhere.21 However, our triaging process was time consuming and lengthy for patients. Streamlining through general practice assessment and referrals may mitigate this barrier to access.

Conclusions

General practitioners are now seen as the central specialty in the diagnosis and management of long COVID.16 Although they are well equipped to be the primary medical contact for patients, they still require education on, and referral options for, therapeutic interventions via allied health. Multidisciplinary rehabilitation is the most effective solution to improve quality of life for patients with severe ongoing symptoms and reduce the burden on general practitioners. Unfortunately, in Australia, unless we shore up access via our public health services or Medicare rebates, this opportunity will be limited to people with significant financial means.
