Management of foot health in people with inflammatory arthritis: British Society for Rheumatology guideline scope

Management of foot health in people with inflammatory arthritis: British Society for Rheumatology guideline scope

The guideline will be developed using the methods and processes outlined in Creating Clinical Guidelines: Our Protocol [1]. This development process to produce guidance, advice and recommendations for practice has National Institute for Health and Care Excellence (NICE) accreditation.

1 Why the guideline is needed

Foot problems are highly prevalent in adults, children and young people with inflammatory arthritis (IA), but their burden is often underestimated by health professionals. People with IA are often frustrated that concerns relating to their feet are ignored [2–4]. There are existing guidelines for foot health that may be applicable to IA. A regional podiatry group has developed management guidelines to support non-specialist podiatrists in the management of people with RA and related foot problems [5]. However, these guidelines are now nine years old and, while they are practitioner-facing, they relate only to RA instead of the wider spectrum of IA, do not include children and young people, and are not sensitive to the foot health needs of people from different cultural and religious backgrounds (e.g. footwear and orthotic device appearance and preferences for different materials). There are also standards embedded in the NICE guideline for RA highlighting the need to treat foot pathology [6]. These standards have an underpinning philosophy that encourages empowered self-care, patient involvement in service design, tailoring of services to patients’ needs, promotion of informed choice, and timely and appropriate access to services where needed. However, they do not make recommendations about specific aspects of clinical management, such as particular foot problems and different rheumatic diseases. Furthermore, there is limited guidance as to when foot health experts should be consulted and there are no recommendations on which assessments or interventions should be performed. Finally, the Arthritis and Musculoskeletal Alliance (ARMA) have previously produced generic patient-facing Standards of Care for people with musculoskeletal foot health problems [7] and children and young people with JIA [8]. These outlined what patients should expect from services at that time, and the latter recognize the need for specialist podiatry reviews for people with JIA. Despite this, neither provide clinicians with guidance for treatment and both standards are now over a decade old. A survey of non-specialist podiatrists in the UK found that over 95% were unaware of existing guidelines [9]. There is a clear need for a national evidence-based clinical guideline for foot health that is aimed at clinicians and focused on IA more widely.

This new BSR guideline will address the assessment and management of foot health in adults, children and young people with IA and will focus specifically on the healthcare setting in the UK. Clear, culturally sensitive guidance regarding evidence-based strategies for the management of foot problems in people with IA will help all clinicians to provide high-quality care for their patients, service providers, and commissioners, to ensure that adequately resourced foot health services are available to meet the needs of patients. The guideline will provide advice to enable a range of clinicians to provide first-line therapy for foot conditions where access to podiatry is limited, and advise when specialist opinions should be sought.

Key facts and figures

IA is an umbrella term encompassing a range of chronic, autoimmune conditions characterised by joint inflammation. These include RA, JIA and spondyloarthropathy (SpA) – which encompasses PsA, AS, reactive arthritis, enteropathic arthritis and undifferentiated SpA.

Despite the introduction of aggressive pharmacological therapies, foot problems frequently occur in IA. Around 90% of people with RA experience foot problems during the course of the disease, including rearfoot and forefoot deformity, tibialis posterior dysfunction, peripheral arthritis, and subluxation and dislocation of the MTP joints, leading to pain and reduced walking ability [10]. The foot is also particularly susceptible to damage in JIA. Foot-related impairment and disability has been shown to persist in over 90% of children and young people with the condition, despite intensive pharmacological therapy [11], and foot problems are also common in adults with JIA. In SpA, foot problems also include peripheral arthritis, dactylitis and enthesitis, particularly at the Achilles tendon, plantar fascia and tibialis posterior tendon insertions but also at many other sites. In PsA specifically, forefoot deformity affects over 90% of people with the condition, while almost two-thirds experience foot pain [12].

Other extra-articular features of IA can manifest in the foot, including peripheral neuropathy and entrapment neuropathies. The risk of peripheral arterial disease is also increased in IA, particularly amongst individuals with a history of steroid use [13]. Long-term steroid use can also contribute to poor tissue viability in the foot, and when combined with joint deformity and poor vascular supply, the risk of tissue breakdown is significantly increased. Foot ulcers are common in IA [14, 15], and in immunosuppressed patients these carry an increased risk of potentially serious infection.

Despite significant advances in the pharmacological management of IA with the advent of whole new classes of medication and a new treatment paradigm, foot problems persist. The impact of foot damage in IA is often underestimated [16] and trivialized, yet people with foot problems consistently report marked reduction in their quality of life, indicating that the impact of foot disorders extends well beyond localized pain and discomfort [17].

Current practice

A person with IA might present to primary or secondary care with foot problems. In some cases, foot problems precede the diagnosis of IA; 31% of cases are known to have had their first IA symptoms in their feet [18]. After diagnosis, foot problems may be monitored as part of the assessment of overall prognosis and disease activity, potentially with follow-up imaging. Some units run multidisciplinary clinics, but more commonly people with foot problems are seen separately by rheumatology and podiatry, sometimes with additional input from physiotherapy, orthotics, occupational therapy or orthopaedic surgery. The presentation of foot problems in IA is diverse, with some people experiencing problems with general nail and skin care, whereas others have pain and change in foot shape and posture (deformity), making it difficult to walk and find suitable footwear. Such problems can have specific challenges for children and young people as their musculoskeletal system is growing and developing. Others may present with neurological or vascular disease affecting the feet, or with foot ulcers. Treatments for foot pain and deformity can include general nail care, callus debridement, foot orthoses, footwear advice and provision, stretching and strengthening exercises, lifestyle advice and surgery. People with persistent active inflammation in the foot may benefit from corticosteroid injections or a change in systemic treatment.

Variation in practice is widespread and the inadequacies of foot care in the UK are well documented. Although National Early Inflammatory Arthritis Audit (NEIAA) data indicated that 76% of rheumatology departments had podiatry access in 2020 [19], a 2021 BSR rheumatology workforce report highlighted that 80% of departments do not have a podiatrist embedded in their multidisciplinary team [20]. Additionally, a recent clinical audit into the adherence of foot health management standards of RA across six National Health Service (NHS) Trusts found that only one podiatry department had the facility to see people with RA within six weeks of their initial diagnosis [21], while cross-sectional and longitudinal cohort studies in secondary care frequently report that only 30% to 40% of people with RA access any form of professional foot care or surgery [22–24].

It has been suggested that better integration of foot health services into rheumatology would be beneficial for people with IA [25]. Referral pathways are often unclear, and the lack of podiatrists within specialist teams means many patients seek foot care from the independent sector or non-specialist podiatrists who may not have the specific knowledge to manage their problems. Poor compliance with current foot health standards amongst podiatry departments is prevalent [21].
