Management of demand for services in public hospitals is a key challenge for the health care system. The situation will intensify with the ageing of Australia’s population and increases in the prevalence of chronic disease and disability. Strategies to date have focused on the acute care sector,1,2 reducing hospital attendances, post-acute support, and management of chronic disease in the community. The rehabilitation sector is generally seen as separate from the acute care system,3,4 and there is relatively little focus on patient flow into and through rehabilitation, or on the secondary and tertiary prevention strategies that optimal rehabilitation intervention can offer. We feel that the lack of focus on rehabilitation is detrimental to our health care system.

Twenty per cent of Australians have a disability, and more than 6% of the population has a profound or severe core-activity limitation.5 With an increasing proportion of older people living alone,6 the ability to keep living in the community is often more dependent on functional independence than on medical factors, suggesting a role for rehabilitation.

Rehabilitation has been defined as “a health strategy . . . that aims to enable people with . . . disability to achieve and maintain optimal functioning in interaction with the environment”.7 In the context of this article, rehabilitation refers to the provision of multidisciplinary, medically directed services that aim to improve the functioning of an individual after illness or injury and that are evidenced by comprehensive assessment of function and realistic and negotiated goals.8

Here, we provide an overview of public rehabilitation services in the two most populous Australian states, New South Wales and Victoria, but many of the issues raised are likely to apply to the rest of the country. We highlight preventable systems factors that contribute to access block “upstream” in the acute care sector and exit block “downstream” in rehabilitation, and present possible solutions. The issues identified relate to people of all ages with disabilities.

Current rehabilitation services in NSW and Victoria

Data on over 53 000 inpatient rehabilitation episodes in Australia for 2006 were recently reported.9 Most of these (39 168 [77.5%]) were in NSW and Victoria (Frances Simmonds, Manager, Austra-lasian Rehabilitation Outcomes Centre, personal communication). Patients were mostly aged over 70 years, but about a fifth were aged under 65 years. More episodes from private hospitals were reported, but patients treated in the public sector tended to be more disabled. Most patients returned to living in the community after discharge. Rehabilitation has been described as the “glue” between the acute care and community sectors.10

Victoria and NSW are generally well served in the availability of public rehabilitation beds and rehabilitation physicians (1 per 62 000 and 1 per 46 000 people, respectively, at June 2008 [Rebecca Forbes, Senior Executive Officer, Australasian Faculty of Rehabilitation Medicine, personal communication] and calculated using Australian Bureau of Statistics estimates). In Victoria, most public rehabilitation beds are in stand-alone facilities, while in NSW, co-location with acute care facilities occurs more frequently. The trend over recent decades has been to re-allocate the role of small hospitals to that of subacute care, including rehabilitation, in an effort to satisfy the political imperative of keeping these hospitals open, while acknowledging that the provision of acute care in small facilities is no longer appropriate.

Ambulatory rehabilitation is generally more widely available in Victoria than in NSW, with the former offering comprehensive outpatient public rehabilitation programs and the availability of home-based rehabilitation, typically for 2–6 weeks.

Problems with the current organisation and delivery of rehabilitation services

System issues, funding and workforce constraints, and conflict between federal and state responsibilities11,12 all contribute to reducing the positive potential of rehabilitation in the acute care hospital and community sectors. Critical factors are outlined below.

Provision of hospital-based care

Functional decline in patients secondary to inactivity is ubiquitous in acute care hospitals, resulting in prolonged recovery times. Systems are generally not in place to minimise this. Preventable complications, such as pressure ulcers,13 falls, malnutrition14 and contractures also affect outcomes and increase length of stay.

In acute care hospitals, rehabilitation services are often not engaged early enough to help prevent functional decline and complications. Delays in obtaining rehabilitation assessments in acute care are common, due to delays in referral or in availability or responsiveness of the rehabilitation team.15 Under-resourcing of allied health staff in some acute care hospitals results in patients receiving minimal therapy and discharge planning once they have been identified for rehabilitation or other subacute care. This contributes to functional decline and increases subsequent length of stay in subacute care.

As private rehabilitation capacity has expanded to target patients with predominantly single-system impairments (eg, elective orthopaedic conditions and milder strokes), the nature of public hospital rehabilitation has moved towards the management of older patients with multiple morbidities and general debility, often requiring ongoing interaction with the acute care system.

We question the appropriateness of providing inpatient rehabilitation services that are isolated from the back-up of an acute care facility — for efficiency, safety and workforce reasons. Acute care patients in need of rehabilitation must wait till they are medically stable before they can be transferred to a stand-alone rehabilitation facility, creating a hiatus in their care (both acute care and rehabilitation). When acute care and rehabilitation hospitals are not collocated, the elective transfer of patients from acute care to rehabilitation often takes place later in the day — effectively wasting a day by the time the admission process is completed. Interruptions to rehabilitation then occur if patients are transferred back to acute facilities for medical review or investigations. In stand-alone facilities, on-site after-hours medical rostering in an environment of workforce shortage is problematic and costly.

For some patients (eg, those who are non-weight-bearing for prolonged periods after lower-limb fractures or those awaiting home modifications), there is a lack of alternative care settings. This results in inappropriate admissions to rehabilitation or longer stays there.

Inpatient rehabilitation exit block for younger people

Little has been done to provide sufficient high-level care for younger people with severe, persistent, acquired disabilities (eg, acquired brain injury or spinal cord injury or damage) who no longer require rehabilitation and are not covered by compensation. There is a lack of options under state programs to accommodate these people, and the restrictions imposed by the federal government on younger people accessing residential aged care compound the problem. Therefore, these patients often wait in rehabilitation for many months until a suitable community solution can be brokered, or for placement — often, in spite of the government restrictions, in a residential aged care facility, after all other options have been exhausted. In NSW, the new Lifetime Care and Support Scheme (http://www.lifetimecare.nsw.gov.au) is seen as a positive step, but this is only available for people with catastrophic injury as a result of a motor vehicle accident.

The lack of funding for paid carers and the bureaucratic processes that restrict and delay the provision of home-based care result in patients being generally limited to 5–7 hours per week of personal care assistance at home. This results in stress to the family providing care and significant out-of-pocket expense. Once determined appropriate, the wait for packages that can provide a greater number of hours of care can take months. In Victoria, the Disability Support Register provides younger patients with access to a package of services to avoid admission to residential aged care via the “my future my choice” program (http://www.dhs.vic.gov.au/disability/improving_supports/my_future_my_choice). However, access to such services can take 4 to 8 months to implement.

Interface with aged care services

Improvements in aged care service provision have focused on care and support rather than on the minimisation and reversal of disability. The federal government’s recently established Transition Care Program offers 8–12 weeks of support with limited therapy to improve the functioning of patients at risk of residential aged care facility admission.16 However, this program is available only to patients aged over 65 years. It is also more akin to restorative care, with the expectation of slow gains over time with good supportive care and minimal therapy, than to intensive specialist rehabilitation. A recent article in the Journal highlighted concerns about the cost-effectiveness of this program compared with alternatives, including rehabilitation.17

Proposals to improve the organisation and delivery of rehabilitation services

There are a number of strategies that can improve service delivery, potentially improving patient flow and outcomes in both acute care and rehabilitation. Implementing these improvements will require cooperation between state and federal governments and greater flexibility by health departments and hospitals as to how rehabilitation services are organised.

Furthermore, a national rehabilitation strategy should be established, as recently proposed by the Australasian Faculty of Rehabilitation Medicine (http://afrm.racp.edu.au/index.cfm?objectid=0F7AE593-9D8B-CDD1-A2096977C34069AA). This would, among other things, improve national rehabilitation policy, planning, service provision, research and workforce development.

In addition to the changes suggested here, there are likely to be other ways in which the acute–subacute–community interface can be improved. The clinical redesign principles described in a recent supplement to the Journal provide a useful framework for progressing this process.18 It is also important to have cooperation and collaboration between rehabilitation and aged care services, to avoid duplication of similar services and to limit delays caused by parallel assessment processes, while at the same time preserving the important differences that each of these fields of expertise offers.

Minimise preventable disability and complications

Rehabilitation can play a major role in minimising preventable disability and complications in hospitalised patients. There is a need for programs to increase activity levels to prevent unnecessary functional decline in patients in both acute and subacute care,19,20 along with early referral to rehabilitation services for patients with significant disability who are likely to require multidisciplinary care. Commencing a multidisciplinary rehabilitation program at an early stage, even while still in acute care, can improve outcomes21-23 and patient flow by reducing length of stay in rehabilitation or avoiding a rehabilitation admission entirely if adequate ambulatory care programs are available.

Use should be made of systems for the early identification15 and referral of patients appropriate for rehabilitation.24

Support younger people with severe disability

A range of suitable and accessible care options for younger27 adults requiring high-level care is needed. Options include smaller group residential homes, adequate funding for home-based carers, and programs similar to the existing Transition Care Program, but with a greater intensity of allied health intervention, if required.

Conclusion

To make the best use of the current wave of hospital and community health system reforms, a focus on the rehabilitation sector is essential. Recent government initiatives, while addressing some of the issues raised, have concentrated on the aged care domain and not on rehabilitation.28,29 Addressing the issues outlined in this article will require a whole-of-government approach, as well as involvement of regional health authorities and local personnel. We feel that the effectiveness of the health care system would be considerably enhanced by these changes, which would help to increase access to inpatient beds (in both the acute and subacute sectors), improve patient outcomes and reduce costs.
