Description of intervention(s) / exposure

This is an observational study that will examine current practice for the management of knee OA. Nine metropolitan-based, community physiotherapy practices and 30 patients with knee OA will be recruited. Patients will be included if they have activity-related joint pain, morning stiffness lasting <30 minutes and are aged over 45 years. All patients who who consent will have their physiotherapy notes audited using a proforma and participate in an interview with the researcher at 6 weeks taking approximately 30 minutes. Patients will also complete three patient reported outcome measures at baseline and 12 weeks taking up to 1 hr. All physiotherapists who consent will be interviewed by the researcher at 6 weeks after the final patient is recruited, each taking approximately 20 minutes.

Statistical methods / analysis

We are aiming for an opportunistic sample size of 30 participants, ideally achieving 3-4 patients per practice. Whilst 12 people typically provide sufficient information for theme saturation in qualitative studies, we aim to enrol participants from each clinic in order to get a mix of socioeconomic backgrounds. Further, the relatively large sample will provide evidence of a trend in efficacy (if there is one), that will inform sample size calculations for future studies.
We are aiming to recruit a minimum of 25 physiotherapists across nine community physiotherapy practices in the Sydney area.

Analysis
Audit of Treatment Notes
Data collected through the auditing of treatment notes will be recorded in Microsoft excel spreadsheets and analysed using descriptive statistics (mean, standard deviation, and proportion) as follows: The percent of patients who received each of the core guideline treatments and the percent of patients who were referred to another healthcare professional for each of the core guideline treatments.
Audited treatment notes will be compared against care that is recommended in guidelines for the conservative management of knee OA. However, descriptive statistics of the patient will determine if all core guideline treatments need to be address. For example, if the patient is obese, weight-management should be discussed, and a referral to a dietician made. But, if they had a BMI < 25, this treatment would be made null.

Primary outcomes of the study include identifying the proportion of patients who are recorded as receiving care according to guidelines, and proportion of patients who have patient-reported outcomes incorporated into their assessment and management plan.
Secondary outcomes of the study include changes in knee pain, knee stiffness, knee function, and polysymptomatic distress at 12 weeks compared to baseline as assessed by Patient Reported outcome Measures (PROMs).

Demographic and clinical characteristics will be collected through the use of PROMs at initial recruitment and 12 weeks. The baseline characteristics of the two cohorts will be presented to demonstrate comparability. The change in PROMS across time for each cohort will also be presented.
Patients experience and perspectives of how their knee OA was managed will be gathered using a semi-structured face to face interview at 6 weeks post recruitment.
Physiotherapists experience and perspectives of how they manage knee OA will be gathered using a semi -structured face to face interview 6 weeks after recruitment is completed.
Semi-structured interviews will be conducted, audio-recorded and transcribed. Data collected from interviews will be recorded in nVivo were it will be categorised and classified. This will reflect both the patients and physiotherapists experiences and perceptions.

Summary

Brief summary

Historically, the management of knee OA has been variable, and often limited to pharmaceutical management and total joint replacement. Recently, evidence-based recommendations for the management of knee OA have been developed by scientific societies and health organisations. Best-practice guidelines for the treatment of knee OA focus on conservative (non-operative) multidisciplinary management that encompasses education, exercise, lifestyle modification and weight-loss where relevant, while promoting self-management. This body of evidence demonstrates that multidisciplinary conservative management of knee OA is efficacious. This observational study aims to discover how knee osteoarthritis patients are currently been managed by community physiotherapists, and if this aligns with recommended guidelines.
