Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A pragmatic randomised controlled trial (RCT) design will be used, with a cross-over waiting-list group. Participants will be allocated with either Group (1): immediate access to the podiatry-triage clinic, or Group (2): 6-month waiting-list allocation prior to accessing the podiatry-triage clinic.

A podiatry-led triage clinic will be provided to participants. This is a pragmatic intervention, where the podiatrist will undertake assessments (clinical and radiographic) provide non-surgical treatments (e.g. physical therapy, footwear modification, orthoses, injections) aimed at managing a specific complaint, rather than a standardised treatment. The intervention will be recorded, and may include no treatment. The podiatrist’s responsibilities will be to evaluate the participant, provide a diagnosis and provide non-surgical treatments where indicated. Participants will be discharged from the orthopaedic waiting-list, with their consent if; (i) their symptoms resolve with non-surgical treatment, (ii) their condition is not amenable to surgical intervention, or (iii) they do not want surgery. Participants will be referred for an orthopaedic consultation if; (i) there is no indication for non-surgical treatment, (ii) they fail non-surgical treatment, or (iii) they request an appointment with a surgeon following their triage appointment(s).

The frequency of the assessment and intervention will be determined by the condition being managed during the 6-month period. Each appointment will be scheduled for 30 minutes.

ii) Categorised as non-urgent following paper triage by orthopaedic surgeon
iii) Aged >= 18 years
iv) Report foot pain of >= 3/10 on a 0-10 rating scale on most days for >=3 months.

Can healthy volunteers participate?
No
Key exclusion criteria
i) History of cognitive impairment,
ii) An inability to understand English or an inability to provide consent.

In relation to participants having “adequate English”, this will be determined during the initial screening process. In accordance with contemporary research, two Single-Item Literacy Screening (SILS) questions will be asked during the screening interviews:

1. How often do you need to have someone help you when you read instructions, pamphlets, or other written material from your doctor or pharmacy? (Never, Rarely, Sometimes, Often, Always)

2. How confident are you filling out medical forms by yourself? (Not at all, A little bit, Somewhat, Quite a bit, Extremely)

Patients who answer “Sometimes”, “Often”, “Always” to the first question and “Somewhat”, “A little bit”, “Not at all” to the second question will be excluded from this study.

Efficacy
Statistical methods / analysis
Aim 1 – foot pain
Comparisons will be made between the change in foot pain, between baseline and 6-month follow-up for the two groups (immediate clinical triage or delayed clinical triage). Measures at 6-months will be analysed using a linear mixed model, with group, participants and baseline measures as fixed factors, a random effect and covariate, respectively. Consistent with the Consolidated Standards of Reporting Trials (CONSORT) guidelines, an intention-to-treat approach will be taken.

Additionally, descriptive statistics will be used to summarise the characteristics of the participants. All data distributions will be explored for normality (visualization and Shapiro-Wilk normality test) to determine the suitability of parametric or nonparametric statistical tests. Between groups differences will be analysed using the independent samples t-test, or the Mann-Whitney U test depending on normality. Gender counts will be compared using the chi-squared test.

Furthermore, differences in age and IRSD between the participants and those that declined to participate will be analysed using the independent samples t-test, or the Mann-Whitney U test depending on normality. Gender counts will be compared using the chi-squared test.

Aim 2 – cost-effectiveness
The cost effectiveness analysis will be conducted using within-trial analysis. The incremental cost-effectiveness ratio (ICER) for the triage clinic compared with no triage clinic will be calculated based on cost/QALY. The cost of the podiatry clinic will be measured from a health system perspective and will be based on clinician wages (podiatrist) and administrative wages in addition to participant specific use of medical imaging and consumables. The podiatrist will be employed 0.2 FTE and appointment times will be standardised. All costs will be measured in 2022 Australian dollars. The health-related utility values from the ED-5D-5L will be used to calculate the QALYs. The model that will be used to assess cost-effectiveness will be a decision tree with a time horizon of 12-months. Uncertainty analysis will be assessed using probabilistic uncertainty analysis as one-way and multi-way uncertainty analysis. The ICER will be assessed as cost-effective based on willingness to pay of $64,000/QALY. The number of appointments for each patient and the discharge rate will be counted and reported descriptively.

In all analyses, a p-value (two-sided) less than 0.05 will be deemed to be statistically significant. All data will be analysed with SPSS v26.0 or Stata 15.

Aim 3 – chronic musculoskeletal pain domains
The within-group change in pain, physical function, psychological health and sleep, will be analysed using paired t-tests or Wilcoxon signed-rank test, depending on normality.

Sample size calculation
The PASS sample size software was used to determine an a priori power analysis for this study. Using a one tail-test of independent groups at a significance level of p < 0.05 and a power of 80%, 59 participants per group are required to detect a clinically significant reduction in foot pain (13 points), assuming a standard deviation of 25.1. Accounting for up to a 20% attrition rate, a total sample size of 148 participants (74 in each group) has been calculated.
