Foot-related health care use in patients with rheumatoid arthritis in an outpatient secondary care center for rheumatology and rehabilitation in The Netherlands: A cohort study with a maximum of fifteen years of followup

A clinical practice guideline for the management of the foot and ankle in rheumatoid arthritis

Rheumatoid arthritis causes progressive joint destruction in the long term, causing a deterioration of the foot and ankle. A clinical practice guideline has been created with the main objective of providing recommendations in the field of podiatry for the conservative management of rheumatoid arthritis. Thus, healthcare professionals involved in foot care of adults with rheumatoid arthritis will be able to follow practical recommendations. A clinical practice guideline was created including a group of experts (podiatrists, rheumatologists, nurses, an orthopaedic surgeon, a physiotherapist, an occupational therapist and patient with rheumatoid arthritis). Methodological experts using GRADE were tasked with systematically reviewing the available scientific evidence and developing the information which serves as a basis for the expert group to make recommendations. Key findings include the efficacy of chiropody in alleviating hyperkeratotic lesions and improving short-term pain and functionality. Notably, custom and standardized foot orthoses demonstrated significant benefits in reducing foot pain, enhancing physical function, and improving life quality. Therapeutic footwear was identified as crucial for pain reduction and mobility improvement, emphasizing the necessity for custom-made options tailored to individual patient needs. Surgical interventions were recommended for cases which were non-responsive to conservative treatments, aimed at preserving foot functionality and reducing pain. Moreover, self-care strategies and education were underscored as essential components for promoting patient independence and health maintenance. A series of recommendations have been created which will help professionals and patients to manage podiatric pathologies derived from rheumatoid arthritis.

Short-term efficacy and limitations of foot care in patients with rheumatoid arthritis

OBJECTIVES

Foot and ankle impairments are major issues in patients with rheumatoid arthritis (RA). Foot deformities often lead to skin disorders, such as callosities, ingrown toenails, and interdigital tinea pedis. This study was aimed at investigating the efficacy and limitations of foot care by experts in patients with RA.

METHODS

Thirty-one patients with RA who began receiving foot care from nurses at our institution between September 2020 and February 2023 were included. Responses to a survey using the self-administered foot evaluation questionnaire (SAFE-Q) for patient-reported outcome measures were compared at baseline, the second visit (1.3 ± 0.5 months after baseline), and the third visit (3.6 ± 1.6 months after baseline).

RESULTS

Scores for 'Pain and pain-related' and 'General health and well-being' components of SAFE-Q markedly improved after foot care. On the other hand, there were no significant differences in the scores for 'Physical functioning and daily living', 'Social functioning', and 'Shoe-related' components during observation periods.

CONCLUSIONS

Foot care for rheumatoid feet is effective in providing pain relief and improving general health and well-being. However, physical and social functioning and footwear issues did not improve. Clinicians must understand the effects and limitations of foot care in patients with RA.

A qualitative study exploring the experiences and perceptions of patients with rheumatoid arthritis before and after wearing foot orthoses for 6 months

Foot pathology in people with rheumatoid arthritis (RA) can have a psychosocial impact, but interventions such as foot orthoses can reduce foot pain, improving physical activity and quality of life. A previous meta-analysis concluded that foot orthoses can relieve pain and disability and enhance patient's well-being. The aim of this study was to explore the experiences of people with RA, before and after wearing foot orthoses for 6 months. Data were collected through digital recordings of semi-structured interviews carried out before and after wearing foot orthoses for 6 months. A thematic analysis of the transcripts was used to identify themes. Six female participants with RA wore foot orthoses for 6 months in Spain. The mean disease duration was more than 10 years. The findings showed three key themes emerged from the data: (1) improvement in physical activity; (2) footwear… a tricky situation and (3) social implications of RA feet. It is concluded that patients reported that wearing foot orthoses can have a positive impact on physical activity and improve general wellness and quality of life. However, to achieve the potential positive benefits, people with RA also needed to wear suitable footwear (defined as footwear which accommodates both the foot and the insole while maintaining the fit and function of the shoe). Despite the positive impact of wearing orthoses, participants stated that complexities of finding suitable footwear acted as a blocker.

Outcomes and potential mechanism of a protocol to optimize foot orthoses in patients with rheumatoid arthritis

Background

Foot problems are highly prevalent in patients with rheumatoid arthritis. Treatment of foot problems related to rheumatoid arthritis often consists of custom made foot orthoses. One of the assumed working mechanisms of foot orthoses is redistribution of plantar pressure by creating a larger weight bearing area. Overall, the reported treatment effect of foot orthoses on foot pain in rheumatoid arthritis is small to medium. Therefore, we developed a foot orthoses optimization protocol for evaluation and adaptation of foot orthoses by using the feedback of in-shoe plantar pressure measurements. The objectives of the present study were: 1) to evaluate the 3-months outcomes of foot orthoses developed according to the protocol on pain, physical functioning and forefoot plantar pressure in patients with foot problems related to rheumatoid arthritis, and 2) to determine the relationship between change in forefoot plantar pressure and change in pain and physical functioning.

Methods

Forty-five patients with foot problems related to rheumatoid arthritis were included and received foot orthoses developed according to the protocol. Outcome measures were assessed at baseline and after three months of wearing foot orthoses in 38 patients. Change scores and effect sizes (ES) were calculated for pain, physical functioning and plantar pressure. In a subgroup of patients with combined forefoot pain and high plantar pressure, the relationship between change in plantar pressure and change in pain and physical functioning was analyzed.

Results

In the total group of 38 patients, statistically significant changes in pain (ES 0.69), physical functioning (ES 0.82) and forefoot plantar pressure (ES 0.35) were found. In the subgroup (n = 23) no statistically significant relationships were found between change in plantar pressure and change in pain or physical functioning.

Conclusion

Foot orthoses developed according to a protocol for improving the plantar pressure redistribution properties lead to medium to large improvements in pain and physical functioning. The hypothesis that more pressure reduction would lead to better clinical outcomes could not be proven.

Systematic review on the comparative effectiveness of foot orthoses in patients with rheumatoid arthritis

Background

Foot orthoses (FOs) are prescribed as an important conservative treatment option in patients with foot problems related to rheumatoid arthritis. However, a broad variation in FOs is used, both in clinical practice and in research. To date, there is no overview on the outcomes of the treatment with different kinds of FOs in patients with rheumatoid arthritis and a specific foot problem. The objectives of the present study were to summarize the comparative effectiveness of FOs in the treatment of various foot problems in patients with rheumatoid arthritis, on the primary outcomes foot function and foot pain, and the secondary outcomes physical functioning, health related quality of life, compliance, adverse events, the costs of FOs and patient satisfaction.

Methods

Studies comparing different kinds of FOs, with a presumed therapeutic effect, in the treatment of foot problems related to rheumatoid arthritis were included. A literature search was conducted in The Cochrane Central Registry for Controlled Trials (CENTRAL), PubMed, EMBASE and PEDro up to May 18th, 2018. Data was meta-analyzed, when this was not possible qualitative data analysis was performed.

Results

Ten studies were identified, with a total number of 235 patients. These studies made a comparison between different materials used (soft versus semi-rigid), types of FOs (custom-made versus ready-made; total-contact versus non-total contact), or modifications applied (metatarsal bars versus domes). Also, different techniques to construct custom-made FOs were compared (standard custom-molding techniques versus more sophisticated techniques). A medium effect for (immediate) reduction of forefoot plantar pressure was found in favor of treatment with soft FOs compared to semi-rigid FOs (SMD 0.60, 95% CI 0.07-1.14; P = 0.03; 28 participants). Other comparisons between FOs resulted in non-significant effects or inconclusive evidence for one kind of FOs over the other.

Conclusions

Foot orthoses made of soft materials may lead to more (immediate) forefoot plantar pressure reduction compared to foot orthoses constructed of semi-rigid materials. Definitive high quality RCTs, with adequate sample sizes and long-term follow-up, are needed to investigate the comparative (cost-) effectiveness of different kinds of foot orthoses for the treatment of foot problems related to rheumatoid arthritis.

Foot Barriers in Patients With Early Rheumatoid Arthritis: An Interview Study Among Swedish Women and Men

OBJECTIVE

Foot impairments are related to reduced mobility and participation restrictions in daily activities in patients with established rheumatoid arthritis (RA). The new biologic medications are effective and reduce disease activity, but not disability to the same extent. Foot impairments are assumed to be related to participation restrictions also in patients with early RA, diagnosed after the introduction of biologic medications. Knowledge of foot impairments needs to be explored further after the introduction of biologic disease-modifying antirheumatic drugs (bDMARDs). The aim of this study was to explore the patients' perspective of foot impairments related to early RA.

METHODS

The sample included 59 patients (ages 20-63 years) who were interviewed about participation dilemmas in daily life using the critical incident technique. The interviews were audio-recorded and transcribed. Data related to foot impairments were extracted and analyzed thematically. A research partner validated the analysis.

RESULTS

Patients with early RA described a variety of participation restrictions related to foot impairments: foot hindrances in domestic life, foot impairments influencing work, leisure activities restricted by one's feet, struggling to be mobile, and foot impairments as an early sign of rheumatic disease.

CONCLUSION

There is a need to focus on foot impairments related to early RA, and for health care professionals to understand these signs. A suggestion for future research is to conduct a longitudinal followup of foot impairment related to medication, disease activity, and disability in patients diagnosed after the introduction of bDMARDs.

Multidisciplinary recommendations for diagnosis and treatment of foot problems in people with rheumatoid arthritis

BACKGROUND

Foot problems in people with rheumatoid arthritis (RA) are highly prevalent and have a substantial impact on quality of life. Healthcare professionals from various professions can be involved in the management of these foot problems. There is currently no consensus on optimal management. Therefore, the aim of the present study was to develop multidisciplinary recommendations for the management of foot problems in people with RA in the Netherlands.

METHODS

The recommendations were based on research evidence and consensus among experts, following published strategies for the development of practice recommendations. The expert group was composed of 2 patients and 22 experienced professionals (rheumatologists, rehabilitation physicians, orthopaedic surgeons, specialized nurses, podiatrists, orthopaedic shoe technicians, pedicurists, and researchers) in the Netherlands. For each developed recommendation i) the level of evidence was determined, and ii) the level of agreement (among the expert group) was set by an anonymous voting procedure using a numeric rating scale. The mean and range of the level of agreement for each recommendation was calculated. A recommendation was approved when ≥70% of the expert group voted an NRS-agreement ≥7.

RESULTS

In total, 41 recommendations were developed. Two recommendations concerned a framework for diagnosis and treatment. Thirty-nine recommendations on foot care were developed: seven on diagnosis (including check-ups of feet and shoes and diagnostic imaging), 27 on treatment (including corticosteroid injections, foot surgery, therapeutic shoes, foot orthoses, exercise therapy, toe-orthoses and toenail-braces, treatment of toenails and skin), four on communication, and one on organisation of RA-related footcare. All recommendations were approved by the expert group. The percentage score of NRS-agreement ≥7 ranged from 80 to 100%.

CONCLUSIONS

These are the first published multidisciplinary recommendations specific to the management of foot problems in people with RA. Multidisciplinary recommendations can provide guidance in timely referrals and access to adequate footcare. More research is needed to strengthen the evidence on diagnosis and treatment of RA-related foot problems. These national recommendations may be a first step towards developing international multidisciplinary recommendations for the management of foot problems in RA.

The effectiveness of therapeutic shoes in patients with rheumatoid arthritis: a systematic review and meta-analysis

The study summarizes the evidence on the effectiveness of therapeutic shoes on foot function, foot pain, physical functioning, health-related quality of life, adherence, adverse events and patient satisfaction in patients with rheumatoid arthritis (RA). Studies investigating the effect of (ready- or custom-made) therapeutic shoes were included. For between-group designs, studies comparing therapeutic shoes versus non-therapeutic shoes were included. A literature search was conducted in The Cochrane Central Registry for Controlled Trials (CENTRAL), PubMed, EMBASE and PEDro up to January 19, 2017. Quantitative data analysis was conducted; when this was not possible qualitative data analysis was performed. Eleven studies were identified. For custom-made shoes, no studies reporting between-group differences were available. Qualitative data-syntheses of the within-group differences resulted in weak evidence for the reduction of foot pain and improvement of physical functioning. For ready-made shoes, one study reported between-group differences, resulting in inconclusive evidence for improvement of foot function. Quantitative data-analyses of within-group differences resulted in a medium to large effect for the reduction of foot pain (SMD 0.60, 95% CI 0.28-0.92; P ≤ 0.001; 184 participants) and a small to medium effect for the improvement of physical functioning (SMD 0.30, 95% CI 0.04-0.56; P = 0.02; 150 participants). Qualitative data-synthesis of within-group differences resulted in weak evidence for improvement of foot function. Within-group results indicate that therapeutic shoes are likely to be effective in patients with RA. Definitive high-quality RCTs are necessary to investigate the between-group effectiveness of therapeutic shoes in patients with RA.

The experience of foot problems and decisions to access foot care in patients with rheumatoid arthritis: a qualitative study

Background

Although foot problems are common in rheumatoid arthritis (RA), the consequences of foot problems from the patient perspective have not been fully explored. The aims of this study were to explore the experience of foot problems and decisions to access foot care services or not in patients with RA.

Methods

Semi structured, one-to-one interviews with patients recruited from 2 UK rheumatology units, purposively sampled for self-reported foot problems and a range of personal/disease characteristics. Inductive thematic analysis was used, with rigour provided by multiple independent analysers. Emerging themes were discussed and agreed by all authors.

Results

Twelve patients participated: 7 female; mean age 56 years (29–72); mean disease duration 12 years (2–27), 5 had accessed foot care services. The ‘Impact’ of foot problems was substantial and formed the underpinning theme, comprising three organising themes: ‘Foot symptoms’; ‘Consequences’; and ‘Cost’. Foot symptoms such as pain and numbness required self-management, and affected daily life (walking, working) leading to social and emotional costs. The global theme, ‘Decision to access foot care or not’, also comprised three organising themes: ‘Access perceived unnecessary’ (no problem, can cope); ‘Access hindered by patients’ perception’; and ‘Access supported by patient and clinician’. Decisions to access foot care or not were complex and influenced by patient beliefs regarding possible treatments and how to access these, and hindered by patient perceptions that their feet were ignored by rheumatology clinicians. Positive experience of foot care encouraged continued utilisation but negative experiences contributed to patients’ decisions to discontinue foot care services.

Conclusions

Foot problems are important issues for patients and impact on many aspects of their physical, social and emotional lives. Patients who had accessed foot care services prioritised their foot problems as an important health care need. However, for others who would like foot care services, personal knowledge and values, and perceived barriers in clinical practice, appear to interact to inhibit foot care access. The extent which these interactions affect overall access to foot care in RA patients in general now needs to be quantified to help to inform and improve the effectiveness of the organisation and delivery of foot care.

Provision of foot health services for people with rheumatoid arthritis in New South Wales: a web-based survey of local podiatrists

Background

It is unclear if podiatric foot care for people with rheumatoid arthritis (RA) in New South Wales (NSW) meets current clinical recommendations. The objective of this study was to survey podiatrists’ perceptions of the nature of podiatric foot care provision for people who have RA in NSW.

Methods

An anonymous, cross-sectional survey with a web-based questionnaire was conducted. The survey questionnaire was developed according to clinical experience and current foot care recommendations. State registered podiatrists practising in the state of NSW were invited to participate. The survey link was distributed initially via email to members of the Australian Podiatry Association (NSW), and distributed further through snowballing techniques using professional networks. Data was analysed to assess significant associations between adherence to clinical practice guidelines, and private/public podiatry practices.

Results

86 podiatrists participated in the survey (78% from private practice, 22% from public practice). Respondents largely did not adhere to formal guidelines to manage their patients (88%). Only one respondent offered a dedicated service for patients with RA. Respondents indicated that the primary mode of accessing podiatry was by self-referral (68%). Significant variation was observed regarding access to disease and foot specific assessments and treatment strategies. Assessment methods such as administration of patient reported outcome measures, vascular and neurological assessments were not conducted by all respondents. Similarly, routine foot care strategies such as prescription of foot orthoses, foot health advice and footwear were not employed by all respondents.

Conclusions

The results identified issues in foot care provision which should be explored through further research. Foot care provision in NSW does not appear to meet the current recommended standards for the management of foot problems in people who have RA. Improvements to foot care could be undertaken in terms of providing better access to examination techniques and treatment strategies that are recommended by evidence based treatment paradigms.
