Abstract Background. Rheumatoid arthritis (RA) as a chronic systemic disease, commonly affects the feet, impacting negatively on patients' quality of life. Specialist podiatrists have a prime role to play in the assessment and management of foot and ankle problems within this patient group. However, it has been identified that in many areas there is no specialist podiatry service, with many patients being managed by non‐specialist podiatrists. Therefore, the North West Clinical Effectiveness Group for the Foot in Rheumatic Diseases (NWCEG) identified the need to develop ‘practitioner facing’ guidelines for the management of specific foot health problems associated with RA. Methods. Members of a guideline development group from the NWCEG each reviewed the evidence for specific aspects of the assessment and management of foot problems. Where evidence was lacking, ‘expert opinion’ was obtained from the members of the NWCEG and added as a consensus on current and best practice. An iterative approach was employed, with the results being reviewed and revised by all members of the group and external reviewers before the final guideline document was produced. Results. The management of specific foot problems (callus, nail pathology, ulceration) and the use of specific interventions (foot orthoses, footwear, patient education, steroid injection therapy) are detailed and standards in relation to each are provided. A diagrammatic screening pathway is presented, with the aim of guiding non‐ specialist podiatrists through the complexity of assessing and managing those patients with problems requiring input from a specialist podiatrist and other members of the rheumatology multidisciplinary team. Conclusion. This pragmatic approach ensured that the guidelines were relevant and applicable to current practice as ‘best practice’, based on the available evidence from the literature and consensus expert opinion. These guidelines provide both specialist and non‐specialist podiatrists with the essential and ‘gold standard’ aspects of managing people with RA‐related foot problems.

Introduction trained to carry out specific care or treatment, or who can refer them to other specialist care if needed. Rheumatoid arthritis (RA) is a chronic systemic disease Foot health service providers should be aware of that commonly affects the feet (Grondal et al., 2008), indications for urgent referrals, surgical referrals and as Shi et al. (2000) identified, virtually 100% of and disease red flags.’ (Standard 22, page 22) patients report foot problems within 10 years of disease onset. The structural and functional changes in the feet often affect gait and mobility (Turner et al., 2006; Despite evidence for the need of podiatry services Woodburn et al., 2002a; Turner et al., 2006), impacting (Williams and Bowden, 2004) and efforts to ensure that negatively on the patient's quality of life (Otter et al., the recommendations made by NICE (2009) and the fi 2010; Wickman et al., 2004) and speci cally restricting PRCA Standards of Care are met, there are identified the choice of footwear (Goodacre and Candy, 2010; problems with access to podiatry services. The problems Williams et al., 2007, 2010). For some people with RA, identified in both the National Audit Office report the structural changes are a factor in foot ulcer (2009) and the Rheumatology Futures Group report development (Firth et al., 2008), with the risk of (2009) was that podiatry was an underused and under‐ infection, particularly if the patient's medical manage- resourced service and that in many areas there was no ment includes the use of immunosuppressive drugs specialist podiatry service.

An earlier review of the function and prevent ulceration and infection, thereby provision of foot health services in rheumatology contributing positively to the patient's quality of life departments in the UK (Redmond et al., 2006) found (Woodburn and Helliwell, 1997). These goals can be that only 50% reported adequate basic foot care services achieved with the use of foot health interventions such and less than one in 10 had formal care pathways or as care of the skin and nails, foot orthoses and specialist mechanisms for referral. Interestingly, a fair proportion ‘ ’ therapeutic footwear. The use of foot orthoses and of RA patients access foot care through non‐specialist therapeutic footwear are supported by national guide- routes. Williams and Bowden (2004) identified that lines (Arthritis and Musculoskeletal Alliance [ARMA], 19% of the 139 patients surveyed accessed foot care 2004; National Institute for Clinical Excellence [NICE], through the private sector and 21% were receiving foot 2009), which also recommend that people with RA care at local NHS by non‐specialist podiatrists. should have access to foot health assessment and In support of specialist foot care, the PRCA Standards management early in the disease process. Foot health of Care are ‘patient facing’ in respect of the service that providers, such as podiatrists, have a prime role to play patients with foot problems can expect. However, due to in the assessment and management of foot and ankle the lack of specialist podiatry provision for RA patients, problems within this patient group (NICE, 2009). This there is a need for ‘practitioner facing’ management view is supported by the Podiatry Rheumatic Care guidelines, to provide non‐specialist podiatrists and Association (PRCA) Standards of Care, ARMA (2004) other foot health providers with specific guidance for and the British Society for Rheumatology (BSR) the management of people with RA‐related foot health (Luqmani et al., 2006). They all strongly advocate the problems. Our aims, therefore, were to develop need for a dedicated and specialist podiatry service for ‘practitioner facing’ guidelines on the management of the diagnosis, assessment and management of foot specific foot health problems associated with RA using problems associated with RA, along with periodic review, an evidence‐based approach and consensus of specialist particularly for those patients with high levels of disease podiatrist practitioners. activity.
