Que mesure l'étude ?
Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
To assess the feasibility of a full clinical trial comparing trained Eye Care Professionals with ophthalmologists in performing laser treatment in line with the established protocols
Délai: from enrollment to the 6 month follow up visit
|
Feasibility will be assessed using pre-specified progression criteria relating to: ECP participation and training completion, participant recruitment, follow-up completion, intervention compliance and retention of clinical equipoise. We will use Red, Amber, Green criteria to determine whether a larger scale trial can be done |
from enrollment to the 6 month follow up visit
|
Mesures de résultats secondaires
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
estimate participant recruitment and retention rates.
Délai: from baseline to 6 month visit
|
to provide an estimate of the consent rates and retention rates by counting the number of patients screened and approached and how many consented. Of those, we will determine how many remained for the full 6 months and if patients withdrew or were lost to follow up we will determine when this occured and, where possible, why |
from baseline to 6 month visit
|
|
assess completeness and quality of outcome data collection.
Délai: from baseline to 6 month visit
|
to assess how well data is collected and how accurate it is by conducting a data cleasning exercise in the database to identify which data are missing and any outliers suggesting data is inaccurate |
from baseline to 6 month visit
|
|
evaluate the feasibility of intervention delivery by trained ECPs
Délai: from baseline to 6 month visit
|
to evalaute whether it is feasible for trained ECPs to deliver the treatment and whether patients accept them. this will include assessing (usign RAG criteria) whether ECPs agree to take part |
from baseline to 6 month visit
|
|
assess the acceptability of the intervention and trial processes to participants and stakeholders.
Délai: from baseline to 6 month visit
|
to assess whether patients consent and remain in the trial and whether stakeholders can adhere to the protocol |
from baseline to 6 month visit
|
|
describe clinical outcome distributions to inform the design of a future definitive trial
Délai: from baseline to 6 month visit
|
we will determine how will various clinical data items are collected in terms of availability and accuracy to determine whether they are suitable for a larger scale study which may use one as the basis for a sample size calculation. Data include number of laser sessions, visual acuity, central retinal thickness, sight loss/retention and various patient questionnaires |
from baseline to 6 month visit
|
|
assess the feasibility of collecting patient-reported outcome and resource-use measures
Délai: from baseline to 6 month visit
|
to determine whether participants complete the questionnaires provided and which questions are missed out / incorrecty completed. We will run missing data reports on the questionnaires to track patterns relating to problematic questions and identify outliers which may be incorrect data |
from baseline to 6 month visit
|
|
explore the resource use and cost drivers associated with ECP-delivered and ophthalmologist-delivered care pathways.
Délai: from baseline to 6 month visit
|
to collect data related to recourse use and other cost drivers associated with the novel treatment pathway using ECPs to determine whether there are cost savings to be made in using ECPs to deliver laser treatment |
from baseline to 6 month visit
