Description of intervention(s) / exposure
This study is an evaluation of the implementation of a bespoke lymphoedema clinical decision support system (CDSS) - www.lymbase.com into three health districts in NSW.
The CDSS (Lymbase) stores patient data relevant to lymphoedema assessment and treatment including clinician reported and patient reported outcomes. It automates calculations for circumference measures and provides a visual display of size change. Lymbase also provides an easy-to-use compression garment search function, accessible for trained lymphoedema therapists. During the trial period clinicians will use the CDSS for all consenting patients. In Stage 1 occurring over four months (intervention period) the pilot study in Sydney Local Health District, will evaluate implementation for patients and clinicians. Revisions based on these findings will be undertaken before rolling the CDSS out in a further three Health Districts (4 month intervention period) and re-evaluating. These revisions might be to the user experience or content of the platform; or they might be to supporting systems such as the website, contact form, explainer videos, etc.
The CPI will undertake a site visit for each site to provide participants with a tablet and access to the software for clinical use in order to provide feedback on the implementation and the CDSS. In addition to semi-structured interviews with clinicians and questionnaires with patients and clinicians an audit of utilisation, including feature utilisation will be undertaken.
A single site pre-post survey will explore the patient experience.

Outcomes
Primary outcome [1] 330933 0
Implementation, (including uptake, impact, barriers and facilitators) of the CDSS will be evaluated. Barriers, facilitators and impact will be explored during the semi-structured interviews and NOMAD-23 questionnaire at the end of each stage.
Timepoint [1] 330933 0
The questionnaire will be sent out on completion of the four month trial and the semi-structured interviews will be booked approximately 2 weeks after trial completion.
Secondary outcome [1] 408139 0
Patient activation Measured using a patient activation measure (PAMS-13) adapted for this population (LSM-PAMS-13). This will be provided to patients during Stage 1 pre-and post the introduction of Lymbase,
Timepoint [1] 408139 0
This will be provided to patients during Stage 1 only with 20 patients recruited in the month prior to the trial and following up these patients at any point that they return during the trial period.
Secondary outcome [2] 408607 0
Uptake will be evaluated over a two week period. This snapshot will compare the number of occasions of service on the eMR schedule against the number of sessions entered on Lymbase. During this period an audit will also be undertaken to evaluate feature utilisation within the platform to see which elements are the most relevant to clinicians. An audit tool based on the inputs for the system has been developed.
Timepoint [2] 408607 0
The single site patient evaluation is completed and presented at the Australasian Lymphology Association Conference. In response to feedback from patients an email/print option was added for the treatment plan.

Minimum age
18 Years
Maximum age
No limit
Sex

Statistical methods / analysis
Rudimentary analysis of frequencies planned (e.g. For the audit of feature utilisation, the items most frequently and least frequently used will be counted. These data will be discussed within the semi-structured interviews with the clinician participants.)
NB Unfortunately the developer costs to retrieve this data prevented the collection of this data. Instead it is a focus in the interviews.
