Development of a national survey on foot involvement among people with psoriatic arthritis in Australia using a best practice approach: a survey development protocol.

BACKGROUND: Limited research to date has defined the nature and extent of foot involvement in a psoriatic arthritis-specific population in Australia and the scale of the problem remains unclear. Survey research provides the ideal opportunity to sample a large population over a wide geographical area. Although quality criteria for survey research have been developed, research shows that adherence is low and that survey studies are poorly reported in peer-reviewed survey articles, which limits the ability to inform future survey design. The objective of this paper was to develop a national survey about foot involvement in people with psoriatic arthritis using a best practice approach. This is a methods paper for the development of survey research. METHODS: A systematic, multi-stage process of survey development was undertaken, which comprised 3 phases: 1) the generation of the conceptual framework and survey content; 2) the development of the survey and pre-testing and 3) development of the survey dissemination strategy. A survey best practice approach was adopted using iterative pre-testing techniques, which included; cognitive debriefing, cultural sensitivity review, survey design expert validation, subject expert validation and pilot testing. Targeted postal and online survey dissemination strategies were developed a priori to optimise the response rates anticipated. RESULTS: A 59-item survey with 8 sections was developed. Findings demonstrated a high survey response (n = 649), high data completeness (83% of respondents reached the end of the survey) and low rates of missing data (below 5% for 95% of respondents). Extensive survey pre-testing among the target population, health professionals and experts improved the overall quality, content validity, functioning and representativeness of the survey instrument, which optimised potential response rates. Clear audit trails that mapped the analytical process at each stage substantiated the rigour of the survey development methods. Robust strategies for sampling, survey dissemination and community engagement were deemed to have made a powerful contribution to response rates and the scale of information collected. CONCLUSIONS: Robust patient-centred methods in survey design were used to create a novel, high-quality survey to comprehensively evaluate psoriatic arthritis-related foot involvement. Transparent and precise description of the survey design and dissemination methods provides useful information to other researchers embarking on survey design in healthcare.

Health professional views on the assessment and management of foot problems in people with psoriatic arthritis in Australia and New Zealand: a qualitative investigation.

BACKGROUND: Active foot disease persists in a high proportion of people with psoriatic arthritis despite the availability of pharmacological and non-pharmacological interventions to modify the course of the disease. Limited information exists on the provision of health care for foot disease in psoriatic arthritis. The objective of this study was to explore the views of health professionals on the assessment and management of people with psoriatic arthritis-related foot involvement. METHODS: Convenience sampling was used to recruit health professionals working in rheumatology outpatient clinics in Sydney, Australia and Auckland, New Zealand. Three focus groups were undertaken to explore the views and experiences of health professionals on the assessment and management of foot problems in people with psoriatic arthritis. All interviews were audio-recorded and transcribed verbatim. Qualitative data was analysed using a constant comparative analytic approach to identify themes. RESULTS: A total of seventeen health professionals participated including rheumatologists, podiatrists and a physiotherapist. Key themes derived from the focus groups suggest that health professionals perceived that people with psoriatic arthritis-related foot problems experience suboptimal management from symptom onset, to diagnosis and treatment. Frustration was expressed throughout discussions relating to lack of appropriate training and expertise required for the specialised management of foot problems typically encountered with psoriatic arthritis and poor access for patients to specialist podiatry services. CONCLUSIONS: This study provides new insight into the perspectives of health professionals on the management of foot problems related to psoriatic arthritis. Deficiencies in the diagnosis, assessment and treatment of foot problems were revealed. To meet the foot health needs of people with psoriatic arthritis, reducing diagnostic delay, improving knowledge and awareness about the disease among people with psoriatic arthritis and health professionals, and increasing specialist podiatry service provision may be required.

Perspectives of patients and health professionals on the experience of living with psoriatic arthritis-related foot problems: a qualitative investigation.

OBJECTIVE: The aim of the study was to explore how foot problems impact on the lives of people with psoriatic arthritis by interviewing patients and health professionals. METHOD: Participants were recruited from outpatient rheumatology clinics in Sydney, Australia, and in Auckland, New Zealand, using a convenience sampling strategy. People with psoriatic arthritis were asked questions in semi-structured interviews about their foot problems and the impact they have on daily living until qualitative data saturation. Focus groups were undertaken with health professionals to explore their understanding of the patient experience of psoriatic arthritis-related foot problems. All interviews were audio-recorded and transcribed verbatim. Constant comparative analysis was used to identify emerging themes from the data. RESULTS: Twenty-one people with psoriatic arthritis-related foot problems and 17 health professionals participated. Three overarching key themes were derived from patients and health professionals: (1) structural and functional foot manifestations, (2) impact on daily life leading to social withdrawal and reduced work productivity and (3) mediating factors influencing the severity of impact from foot problems on their lives such as social support, self-management strategies and experiences of health care. CONCLUSION: Foot problems caused functional disability and altered self-concept, which lead to a cascade of social, economic and psychological consequences. People with foot problems contend with profound disruption to their functioning and life roles. Whilst health professionals recognised the functional and visual impact that foot problems have on daily life, the emotional burden may be under-appreciated. Future work to determine the scale and types of foot problems in psoriatic arthritis is required.

An assessment of strapping techniques commonly used for pronated foot deformities.

BACKGROUND: This study investigated the effects of two low-Dye and two high-Dye strapping techniques that are commonly used to treat pronatory sequelae. METHODS: Plantar pressure distribution in normal adults with a pronated foot type was assessed with a commercially available pressure platform system. Twenty study participants first walked across the platform barefoot and then with each of the four strapping conditions applied. The footprints were averaged and divided into seven areas for analysis. RESULTS: Paired t tests found significant differences between the barefoot and strapping conditions. Overall, there was a general lateralization of pressures indicating an antipronation effect from all strapping conditions. Low-Dye strap 2, used to limit the degree of calcaneal eversion, produced the most significant changes at the foot pressure areas analyzed. CONCLUSIONS: The data reported in this study suggest that the four strapping techniques offer different levels of control, and this should be considered during the decision-making process and clinical management of pronatory conditions. It was the contention of this study that low-Dye strap 2 was the most effective strapping technique to control foot mechanics associated with a pronated foot type.

Adverse family social circumstances and outcome in pediatric cardiac transplant recipients at a UK center.

BACKGROUND: Socioeconomic disadvantage is known to prejudice certain health-related outcomes. METHODS: Our objective was to establish whether adverse social circumstances are linked to rejection events after pediatric cardiac transplant in a UK context. A retrospective observational cohort study was conducted including 78 of 85 children who underwent cardiac transplantation between 2001 and 2005. RESULTS: Family social circumstances included: 36 (46%) unemployed/manual occupation; 29 (37%) non-home owners; 16 (21%) single parents; income support in 31 (40%); and 2 or more further children in 34 (44%). Adverse social risk factors were evenly distributed throughout the cohort in terms of other demographic variables. The rate for a first rejection event was 0.10 (95% confidence interval [CI] 0.07 to 0.15) episode per patient per year, and for late rejection was 0.04 (95% CI 0.02 to 0.07) episode per patient per year. There was some evidence that children from non-home-owning families (hazard ratio [HR] 0.31, 95% CI 0.11 to 0.82, p = 0.02) and those on income support (HR 0.43, 95% CI 0.18 to 1.04, p = 0.06) had reduced risk of early/all first-time rejection episodes. Other social risk factors were unrelated to early rejection. No relationship was found between any social factor and late rejection episodes or low immunosuppression levels at clinic visits 3, 6 or 12 months post-transplant. CONCLUSIONS: Children from more adverse circumstances were not predisposed to rejection episodes. To date, there is no evidence to support a policy of declining children for transplantation on psychosocial grounds in the UK.

Cost-effective faster wound healing with a sustained silver-releasing foam dressing in delayed healing leg ulcers--a health-economic analysis.

The aim of this analysis was to examine the cost-effectiveness of Contreet Foam (A) in comparison with three other commonly used venous leg ulcer treatment protocols: Aquacel Ag (B), Actisorb Silver (C) and Iodoflex (D). A health-economic analysis reflecting the UK treatment practice and cost structure was performed. The analysis was set up to assess the cost of relative wound area reduction over a 4-week treatment period. The model was validated by a UK expert panel consisting of four wound care specialists. To assure that the 4-week model had a realistic link to cost-effectiveness of complete wound healing, a Markov analysis was also performed. Sensitivity analyses were carried out to ensure validity. Protocol A and C proved to be the most effective treatments. The mean relative reduction in wound area after 4 weeks of treatment was 50.2% (protocol A), 23.9% (protocol B), 44.6% (protocol C) and 36.0% (protocol D). Cost-effectiveness ratios showed that protocol A proved to be the most cost-effective treatment, and protocol B the least. The cost per percentage reduction in wound area was 9.50 UK pounds for protocol A, compared to 16.50-17.60 UK pounds for the other treatment options. The cost-effectiveness of complete healing (Markov analysis) and sensitivity analyses confirmed these results. Using Contreet Foam instead of the other dressing alternatives may imply savings of 2.2-4.4 million UK pounds per year to the National Health Service.
